It is also to be understood that the specific devices and processes illustrated in the attached drawings, and described in the following specification, are simply exemplary embodiments of the inventive concepts defined herein. Hence, specific dimensions and other physical characteristics relating to the embodiments disclosed herein are not to be considered as limiting, unless expressly stated otherwise.
- The reference number 10 (
FIG. 1 ) generally designates a vehicle embodying the present invention. In the illustrated example, thevehicle 10 includes afront vehicle portion 12 and arear vehicle portion 14. A joint 16 articulates between thefront vehicle portion 12 and therear vehicle portion 14. Thejoint 16 can be a powered joint or a passive joint. While anyjoint 16 could be used, an example of a powered joint that could be used is disclosed in U.S. Patent Application No. 61/625,962, entitled ARTICULATION AND OSCILLATION JOINT FOR VEHICLE, the entire contents of which are hereby incorporated herein by reference. While thevehicle 10 is illustrated as having a pivotedfront vehicle portion 12 and arear vehicle portion 14, it is contemplated that thevehicle 10 could be formed of a single fixed body. - The illustrated
front vehicle portion 12 propels thevehicle 10. Thefront vehicle portion 12 includes an engine for driving thevehicle 10 and at least one pair of drivenwheels 17 for propelling the vehicle 10 (e.g., four wheel drive with two pairs of driven wheels 17). The pair of drivenwheels 17 can be connected by a solid axle or cradle axle. Cradle axles are well known to those skilled in the art and any cradle axle can be used. For example, thefront vehicle portion 12 can have the cradle axle discussed in U.S. Pat. No. 4,082,377 entitled AXLE CRADLE MOUNTING HAVING ELASTOMERIC SPHERICAL BUSHINGS, the entire contents of which are hereby incorporated herein by reference. Therear vehicle portion 14 can comprise a trailer or any other structure and can include at least one axle (solid or cradle) having a pair ofwheels 19 connected to ends thereof. - In the illustrated example, the
front vehicle portion 12 includes aboom 20 that can rotate about ahorizontal axis 25 relative to thefront vehicle portion 12 by a horizontalaxis pivot assembly 30 having apivot actuator 26. Theboom 20 can be used for carrying anything on an end thereof. In the illustrated example, theboom 20 includes an articulatingnozzle 22 on an end thereof. The articulatingnozzle 22 can be used in any application including for spraying a fluid therethrough for use in mining as is well known to those skilled in the art. The fluid is supplied to thenozzle 22 from the vehicle throughtubing 36 connected to theboom 20. - The illustrated
boom 20 includes afirst arm 24 connected to the horizontalaxis pivot assembly 30, asecond arm 28, athird arm 32 and afourth telescoping arm 34 having the articulatingnozzle 22 on a distal end thereof. Thefirst arm 24, thesecond arm 28, thethird arm 32 and thefourth telescoping arm 34 are pivotable relative to each other to allow theboom 20 to move from a folded position as illustrated inFIG. 1 to an unfolded position as illustrated inFIG. 3 . Furthermore, thefourth telescoping arm 34 can be extended from a retracted position as illustrated inFIG. 1 to an expanded position as illustrated inFIG. 4 . Certain terminology will be used in the following description for convenience in reference only, and will not be limiting. For example, the words “distal” and “distally” will refer to the direction toward the end of theboom 20 as illustrated in the unfolded position inFIG. 3 , which includes thenozzle 22, and the words “proximal” and “proximally” will refer to the direction toward the end of theboom 20 which is connected to thefront vehicle portion 12 and that is furthest from thenozzle 22. InFIGS. 3-5 and 7-9, the distal side is a right side of the drawing and a proximal side is a left side of the drawing. Said terminology will include the words specifically mentioned, derivatives thereof, and words of similar import. - In the illustrated example, the horizontal axis pivot assembly 30 (
FIGS. 1-5 ) allows theboom 20 to rotate about thehorizontal axis 25 with thepivot actuator 26. Thepivot actuator 26 includes anexternal cylinder 38 and an internal cylinder 40 (or similar structure) that rotates relative to the external cylinder 38 (seeFIG. 6 ). Thepivot actuator 26 also includes aproximal cap 42 connected to a proximal side of theinternal cylinder 40 and adistal cap 44 connected to a distal side of theinternal cylinder 40. Theproximal cap 42 and thedistal cap 44 have substantially the same diameter as theexternal cylinder 38 to cover ends of the same (with a seal between thecaps external cylinder 38 to allow thecaps internal cylinder 40 relative to the external cylinder 38). Thepivot actuator 26 can be powered to actively rotate theboom 20 relative to thevehicle 10 about thehorizontal axis 25 extending through a center of thepivot actuator 26. Thepivot actuator 26 can be the actuator disclosed in U.S. Pat. No. 5,447,095 entitled ACTUATOR WITH RING GEAR AND METHOD OF MANUFACTURING SAME, the entire contents of which are hereby incorporated herein by reference. Thepivot actuator 26 can also be an L30 helical, hydraulic actuator as sold by Helac Corporation® of Enumclaw, Washington. Thepivot actuator 26 can be powered hydraulically or by other means. As illustrated inFIG. 1 , theexternal cylinder 38 hashydraulic lines 46 connected thereto for supplying thepivot actuator 26 with hydraulic fluid under pressure (from a source of pressurized fluid on the vehicle 10) to power thepivot actuator 26. - The illustrated
external cylinder 38 of thepivot actuator 26 of the horizontalaxis pivot assembly 30 is fixedly connected to thevehicle 10 to allow theinternal cylinder 40 to rotate about thehorizontal axis 25. Thefront vehicle portion 12 of thevehicle 10 includes aproximal connection collar 48 and adistal connection collar 50. Theproximal connection collar 48 includes a substantially block-shapedbase plate 52 and aring collar portion 54 extending from thebase plate 52. Thebase plate 52 of theproximal connection collar 48 is fixed to thefront vehicle portion 12 and thering collar portion 54 surrounds an exterior periphery of a proximal side circumferential surface of theexternal cylinder 38 of thepivot actuator 26. Thering collar portion 54 of theproximal connection collar 48 is fixed to theexternal cylinder 38 of thepivot actuator 26 by any means (e.g., fasteners). Similarly, thedistal connection collar 50 includes a substantially block-shapedbase plate 56 and aring collar portion 58 extending from thebase plate 56. Thebase plate 56 of thedistal connection collar 50 is fixed to the front vehicle portion 12 (by, e.g., fasteners) and thering collar portion 58 surrounds an exterior periphery of a distal side circumferential surface of theexternal cylinder 38 of thepivot actuator 26. Thering collar portion 58 of the distalside connection collar 50 is fixed to theexternal cylinder 38 of thepivot actuator 26 by any means (e.g., fasteners). It is contemplated that theproximal connection collar 48 and thedistal connection collar 50 could be fixed to a plate or similar structure rotatably connected to thevehicle 10 to allow theboom 20 to be rotatable about a vertical axis to provide even greater range of motion for theboom 20. - In the illustrated example, the horizontal
axis pivot assembly 30 further includes apivot connection 60 fixed to theproximal cap 42 and thedistal cap 44 and connected to thefirst arm 24 of theboom 20 for transferring rotary motion of thepivot actuator 26 to thefirst arm 24 of theboom 20. Thepivot connection 60 includes atop plate 62 fixed to top edges of theproximal cap 42 and thedistal cap 44. Thetop plate 62 is substantially I-shaped when viewed from above and includes aproximal side end 64, adistal side end 66 and athin extension 68 extending between theproximal side end 64 and thedistal side end 66. A top of theproximal cap 42 is fixed to the proximal side end 64 (by, e.g., fasteners) and a top of thedistal cap 44 is fixed to the distal side end 66 (by, e.g., fasteners). A plurality ofangled struts 67 can extend between the proximal surface of theproximal cap 42 and a bottom surface of theproximal side end 64 of thetop plate 62 to reinforce the connection between theproximal cap 42 and thetop plate 62. Thetop plate 62 rotates with theinternal cylinder 40 of thepivot actuator 26, thedistal cap 44 and theproximal cap 42. Thedistal cap 44 and the distal side end 66 of thetop plate 62 are fixed to thefirst arm 24. - The illustrated
first arm 24 of theboom 20 is fixed to the horizontalaxis pivot assembly 30 to allow the horizontalaxis pivot assembly 30 to rotate thefirst arm 24 and theboom 20 about thehorizontal axis 25. Thefirst arm 24 includes a pair of parallelplanar side walls 70, an angledmiddle wall 72 and anend wall 74. The pair of parallelplanar side walls 70 have a proximal side edge connected to thedistal cap 44 of the horizontalaxis pivot assembly 30. A pair ofco-planar tabs 76 extend from a distal edge of thetop plate 62 of the horizontalaxis pivot assembly 30 and are connected to proximal side top edges of the pair of parallelplanar side walls 70 of thefirst arm 24. The angledmiddle wall 72 of thefirst arm 24 extends between the pair of parallelplanar side walls 70 and is connected thereto. The angledmiddle wall 72 has a higher proximal side connected to a bottom of the distal side end 66 of thetop plate 62 of the horizontalaxis pivot assembly 30. A lower distal side of the angledmiddle wall 72 terminates at a bottom distal side of thefirst arm 24. Theend wall 74 extends between the pair of parallelplanar side walls 70 in a substantially vertical orientation. A lower edge of theend wall 74 is spaced from the lower distal side of the angledmiddle wall 72 to create a secondarm receiving space 78 therebetween. Thesecond arm 28 is pivotally connected to thefirst arm 24. - In the illustrated example, the second arm 28 (
FIG. 7 ) is connected to thefirst arm 24 of theboom 20 and is configured to be forcibly pivoted relative to thefirst arm 24. Thesecond arm 28 includes a pair of substantially parallelside wall assemblies 80, apivot block 82 and an angled steppedplate 84. Each of the substantially parallelside wall assemblies 80 includes aninside plate 86, anoutside plate 88 and a substantially oval spanningplate 90. The substantially oval spanningplate 90 extends between and is connected to peripheries of theinside plate 86 and theoutside plate 88. Thepivot block 82 is connected to and extends between the pair of substantially parallelside wall assemblies 80 at the end of thesecond arm 28 connected to the first arm 24 (i.e., the proximal end of thesecond arm 28 is connected to the distal end of the first arm 24). The angled steppedplate 84 also is connected to and extends between the pair of substantially parallelside wall assemblies 80. The angled steppedplate 84 includes, moving from a proximal side to a distal side thereof, abottom step 91 and atop step 92, with a middleangled plate 94 extending between thebottom step 91 and thetop step 92. The angled steppedplate 84 also includes an upperangled plate 96 at a distal end of thetop step 92. Thebottom step 91 is located adjacent a firstlongitudinal edge 98 of the pair of substantially parallelside wall assemblies 80, with the upperangled plate 96 facing away from thefirst arm 24. The pair of substantially parallelside wall assemblies 80 and an area below the middleangled plate 94, thetop step 92 and the upperangled plate 96 define a thirdarm receiving space 100. - The illustrated
second arm 28 is pivotally connected to thefirst arm 24 and a first articulatingassembly 102 connected therebetween forces rotation of thesecond arm 28 relative to thefirst arm 24. As illustrated inFIG. 4 , thesecond arm 28 is connected to thefirst arm 24 by inserting the proximal end of thesecond arm 28 having thepivot block 82 into the secondarm receiving space 78 of thefirst arm 24. Apivot pin 101 extends through the pair of parallelplanar side walls 70 of thefirst arm 24, the pair of substantially parallelside wall assemblies 80 of thesecond arm 28 and thepivot block 82 of thesecond arm 28 to allow thesecond arm 28 to pivot relative to thefirst arm 24. - In the illustrated example, the first articulating
assembly 102 includes a firstexpandable cylinder 104 having a proximal end pivotally connected to thefirst arm 24 by afirst pin 106 and a distal end pivotally connected to thesecond arm 28. The distal end of the firstexpandable cylinder 104 is connected to thesecond arm 28 at a location adjacent a center area of thesecond arm 28, but closer to thethird arm 32 than the first arm 24 (at a location adjacent an end of thebottom step 91 of the angled stepped plate 84). Thefirst pin 106 extends between the pair of parallelplanar side walls 70 above theend wall 74 of thefirst arm 24. The firstexpandable cylinder 104 includes a ring surrounding thefirst pin 106 in acenter area 107 thereof. A pair ofsleeves 108 surround thecenter area 107 of thefirst pin 106 to maintain a position of the firstexpandable cylinder 104 on thefirst arm 24. The firstexpandable cylinder 104 can comprise a pair of telescoping tubes, with the interior tube being driven hydraulically or pneumatically into and out of the exterior tube. When the firstexpandable cylinder 104 is in a contracted position, the distal end of thesecond arm 28 connected to thethird arm 32 rotates away from thefirst arm 24 as illustrated inFIG. 3 (although thefirst arm 24 and thesecond arm 28 could be further extended until thefirst arm 24 and thesecond arm 28 are substantially linear). When the firstexpandable cylinder 104 is in an expanded position, the distal end of thesecond arm 28 connected to thethird arm 32 rotates toward thefirst arm 24 as illustrated inFIG. 2 . A driver of thevehicle 10 and/or a person outside of thevehicle 10 can control expansion or contraction of the firstexpandable cylinder 104 using control levers and/or button (or similar controls). - The illustrated third arm 32 (
FIG. 8 ) is pivotally connected to thesecond arm 28. Thethird arm 32 includes a U-shapedproximal end member 110, arectangular center tube 112, a fourtharm support member 114 and a U-shapeddistal end member 116. The U-shapedproximal end member 110 includes a pivot blockcylindrical base 118 and a pair of parallelplanar arms 120. The pair of parallelplanar arms 120 of the U-shapedproximal end member 110 abut opposite side faces 122 of therectangular center tube 112 to connect the U-shapedproximal end member 110 to therectangular center tube 112. The fourtharm support member 114 extends from atop face 124 of therectangular center tube 112. The fourtharm support member 114 has an inverted U-shape and includes a pair ofparallel support legs 126 and an angledtop plate 128. As discussed in more detail below, thefourth telescoping arm 34 rests on the angledtop plate 128 of the fourtharm support member 114 when theboom 20 is in the folded position. The U-shapeddistal end member 116 includes aproximal block 130 connected to a distal end of therectangular center tube 112 and a pair ofparallel side plates 132 connected to sides of theproximal block 130. - The illustrated
third arm 32 is pivotally connected to a distal end of thesecond arm 28 and a second articulatingassembly 134 connected therebetween forces rotation of thethird arm 32 relative to thesecond arm 28. As illustrated inFIG. 2-4 , thethird arm 32 is connected to thesecond arm 28 by inserting the proximal end of thethird arm 32 with the U-shapedproximal end member 110 having the pivot blockcylindrical base 118 into the thirdarm receiving space 100 of thesecond arm 28. Apivot pin 111 extends through the pair of substantially parallelside wall assemblies 80 of thesecond arm 28 surrounding the thirdarm receiving space 100 and the pivot blockcylindrical base 118 of the U-shapedproximal end member 110 of thethird arm 32 to allow thethird arm 32 to pivot relative to thesecond arm 28. - In the illustrated example, the second articulating
assembly 134 includes a secondexpandable tube 136 having a first end pivotally connected to thesecond arm 28 by a secondarm connection assembly 138 and to thethird arm 32 by a thirdarm connection assembly 140. The secondexpandable tube 136 can comprise a pair of telescoping tubes, with a smallerinterior tube 142 being driven hydraulically or pneumatically into and out of a larger exterior cylinder 144 (seeFIG. 3 ). - The illustrated larger
exterior cylinder 144 is connected to the secondarm connection assembly 138 of thesecond arm 28 and is able to pivot relative thereto. The second arm connection assembly 138 (FIG. 7 ) comprises apivot pin 146 extending substantially perpendicularly from one of the substantially parallelside wall assemblies 80 of thesecond arm 28 and a W-shapedreceiver 148 having thepivot pin 146 extending through threeparallel arms 150 of the W-shapedreceiver 148. It is contemplated that thepivot pin 146 and the W-shapedreceiver 148 could be rotatable relative to or fixed in position on thesecond arm 28. Thelarger exterior cylinder 144 of the secondexpandable tube 136 has a U-shaped fork extending therefrom on an end opposite to the smallerinterior tube 142. Tines of the U-shaped fork are inserted into receiving spaces between pairs of the threeparallel arms 150 of the W-shapedreceiver 148 and thepivot pin 146 extends through the tines of the U-shaped fork to allow thelarger exterior cylinder 144 to pivot about thepivot pin 146. - In the illustrated example, the smaller
interior tube 142 is connected to the thirdarm connection assembly 140 and is able to pivot relative thereto. The thirdarm connection assembly 140 comprises atube 154 extending perpendicularly from aside face 156 of one of the parallelplanar arms 120 of the U-shapedproximal end member 110 of thethird arm 32. Thetube 154 includes a pair ofparallel slots 158 in a lower face thereof, with a pair oflobes 160 extending from the lower face of thetube 154 on opposite sides of the pair ofparallel slots 158. Anend support plate 162 is connected to a terminal end of thetube 154. Apivot pin 164 extends through theend support plate 162, thelobes 160 and into theside face 156 of the one of the parallelplanar arms 120 of the U-shapedproximal end member 110 of thethird arm 32. The smallerinterior tube 142 of the secondexpandable tube 136 has a U-shaped fork extending therefrom on an end opposite to thelarger exterior cylinder 144. Tines of the U-shaped fork are inserted into theparallel slots 158 in thetube 154, with thepivot pin 164 extending through the tines of the U-shaped fork to allow the smallerinterior tube 142 to pivot about thepivot pin 164. - When the second
expandable tube 136 is in a contracted position, the distal end of thethird arm 32 connected to thefourth telescoping arm 34 rotates away from thesecond arm 28 as illustrated inFIG. 3 (although thesecond arm 28 and thethird arm 32 could be further extended until thesecond arm 28 and thethird arm 32 are substantially linear). When the secondexpandable tube 136 is in an expanded position, the distal end of thethird arm 32 connected to thefourth telescoping arm 34 rotates toward thesecond arm 28 as illustrated inFIG. 2 . A driver of thevehicle 10 and/or a person outside of thevehicle 10 can control expansion or contraction of the secondexpandable tube 136 using control levers and/or button (or similar controls). - The illustrated fourth telescoping arm 34 (
FIG. 5 ) is pivotally connected to the distal end of thethird arm 32.

Each of theconnection panels 176 includes a substantially alignedtop opening 180 and a bottom opening 181 (illustrated as being vertically aligned inFIG. 9 ). Each of theconnection panels 176 also includes aconnection portion 182 distally located from the substantially alignedtop opening 180 andbottom opening 181. Theconnection portion 182 of theconnection panels 176 are connected to the proximal end of thetube 174. Apivot pin tube 184 extends between thetop openings 180 in theconnection panels 176. A pivot pin extends through thepivot pin tube 184 to pivotally connect a proximal end of thefourth telescoping arm 34 to the distal end of thethird arm 32. A distal end of the proximalinner telescoping tube 168 slides into a proximal end of themiddle telescoping tube 170. The proximal end of themiddle telescoping tube 170 includes astop member 186 configured to abut theconnection panels 176 for preventing the proximalinner telescoping tube 168 from fully sliding into the proximal end of themiddle telescoping tube 170. The proximalinner telescoping tube 168 and themiddle telescoping tube 170 have mating structure therein for telescoping the proximalinner telescoping tube 168 into and out of the proximal end of themiddle telescoping tube 170 as is well known to those skilled in the art (e.g., a hydraulic extendable tube connected to each of the proximalinner telescoping tube 168 and the middle telescoping tube 170). - A proximal end of the illustrated distal
outer telescoping tube 172 is configured to receive a distal end of themiddle telescoping tube 170 therein. The proximal end of the distalouter telescoping tube 172 includes astop member 187 configured to abut thestop member 186 on themiddle telescoping tube 170 for preventing themiddle telescoping tube 170 from fully sliding into the proximal end of distalouter telescoping tube 172. The distalouter telescoping tube 172 and themiddle telescoping tube 170 have mating structure therein for telescoping themiddle telescoping tube 170 into and out of the proximal end of the distalouter telescoping tube 172 as is well known to those skilled in the art (e.g., a hydraulic extendable tube connected to each of the distalouter telescoping tube 172 and the middle telescoping tube 170). The distalouter telescoping tube 172 includes atube 188 having anozzle holding assembly 190 on a distal end thereof. - In the illustrated example, the nozzle holding assembly 190 (see
FIGS. 2 , 3 and 9) holds the articulatingnozzle 22. Thenozzle holding assembly 190 includes a proximalU-shaped plate 192, a holdingtube 196, aU-shaped pivot connector 198 and aX-shaped pivot connector 200. The proximalU-shaped plate 192 is spaced from the distal end of the distalouter telescoping tube 172 and extends upwardly from atop surface 202 of thetube 188. The proximalU-shaped plate 192 includes a spanningwall 204 and a pair orparallel connection walls 206. Theconnection walls 206 are parallel to opposite side surfaces 208 of thetube 188 and includeextension portions 210 connected to the side surfaces 208 of thetube 188. The holdingtube 196 extends from a distal face of the spanningwall 204 beyond the distal end of thetube 188. TheU-shaped pivot connector 198 includes amiddle panel 212 connected to a distal end of the holdingtube 196 and a pair ofparallel arms 214 extending in a distal direction from themiddle panel 212. The Y-shapedpivot connector 200 includes abase block 216 located between thearms 214 of theU-shaped pivot connector 198 and configured to pivot relative thereto. The Y-shapedpivot connector 200 also includes a pair of holdingsupports 218 having the articulatingnozzle 22 extending throughthrough. The Y-shapedpivot connector 200 is configured to pivot relative to theU-shaped pivot connector 198 to pivot the articulatingnozzle 22 about the distal end of thefourth telescoping arm 34. The Y-shapedpivot connector 200 can be forced to pivot relative to theU-shaped pivot connector 198 in any manner well known to those skilled in the art (e.g., a rotary actuator connected located within the holdingtube 196 and connected to the Y-shapedpivot connector 200 for rotating the Y-shapedpivot connector 200 relative to theU-shaped pivot connector 198 under control of an operator). - The illustrated proximal end of the
fourth telescoping arm 34 is pivotally connected to the distal end of thethird arm 32. As illustrated inFIGS. 2-4 , thefourth telescoping arm 34 is connected to thethird arm 32 by inserting theconnection panels 176 at the proximal end of thefourth telescoping arm 34 into a fourtharm receiving space 185 located between the pair ofparallel side plates 132 of thethird arm 32. Apivot pin 183 extends through a pair of co-lineardistal openings 228 in the pair ofparallel side plates 132 and through thebottom openings 181 in theconnection panels 176 to pivotally connect thefourth telescoping arm 34 to thethird arm 32. - In the illustrated example, a third articulating
assembly 220 connected between thefourth telescoping arm 34 relative to thethird arm 32 forces rotation of thefourth telescoping arm 34 relative to thethird arm 32. The third articulatingassembly 220 includes a thirdexpandable cylinder 234, which can comprise a pair of telescoping tubes, with a smallerinterior tube 240 being driven hydraulically or pneumatically into and out of a largerexterior tube 238 having a first end pivotally connected to thethird arm 32. The largerexterior tube 238 of the thirdexpandable cylinder 234 is connected to a thirdarm tube support 236 of thethird arm 32. As illustrated inFIGS. 2 , 3 and 8, the thirdarm tube support 236 comprises a pair ofplates 235 having alignedopenings 237. Apin 239 extends through the alignedopenings 237 and into a proximal end of the largerexterior tube 238 of the thirdexpandable cylinder 234, thereby allowing the thirdexpandable cylinder 234 to pivot relative to thethird arm 32. A distal end of the thirdexpandable cylinder 234 is connected to aknuckle assembly 241 connected to both the distal end of thethird arm 32 and thefourth telescoping arm 34. - The illustrated
knuckle assembly 241 allows thefourth telescoping arm 34 to rotate about the distal end of thethird arm 32. Theknuckle assembly 241 includes a pair of outsidecurved knuckles 224 and a pair of insidecurved knuckles 222. The pair of outsidecurved knuckles 224 each have a proximal end pivotally connected to the pair ofparallel side plates 132 of thethird arm 32 by a pin or pins 225 extending throughproximal openings 230 in the pair ofparallel side plates 132 and the proximal ends of the outsidecurved knuckles 224. A distal end of the outsidecurved knuckles 224 is pivotally connected to apin 232 extending through a distal end of the smallerinterior tube 240 of the thirdexpandable cylinder 234. Thepin 232 connected to the distal end of the outsidecurved knuckles 224 and the distal end of the smallerinterior tube 240 is also pivotally connected to a proximal end of the pair of insidecurved knuckles 222. A distal end of the pair of insidecurved knuckles 222 is pivotally connected to apivot pin 245 that extends through thepivot pin tube 184 and thetop opening 180 of theconnection panels 176 of thefourth telescoping arm 34. - When the third
expandable cylinder 234 is in a contracted position, the distal end of thefourth telescoping arm 34 having thenozzle 22 thereon rotates toward thethird arm 32 as illustrated inFIG. 2 . When the thirdexpandable cylinder 234 is in the contracted position, the distalouter telescoping tube 172 will rest on the angledtop plate 128 of the fourtharm support member 114 of thethird arm 32. When the thirdexpandable cylinder 234 moves to an expanded position, the smallerinterior tube 240 of the thirdexpandable cylinder 234 pushes thepin 232, thereby causing the pair of outsidecurved knuckles 224 to rotate about thepin 225 in theproximal openings 230 in the pair ofparallel side plates 132 of thethird arm 32. Furthermore, the smallerinterior tube 240 of the thirdexpandable cylinder 234 also pushes thepin 232 to thereby cause the pair of insidecurved knuckles 222 to rotate about thepivot pin 245 extending through thepivot pin tube 184 and thetop opening 180 of theconnection panels 176 of thefourth telescoping arm 34. Moving the thirdexpandable cylinder 234 to the expanded position causes the distal end of thefourth telescoping arm 34 having thenozzle 22 thereon to rotate away from the angledtop plate 128 of the fourtharm support member 114 of thethird arm 32 as illustrated inFIGS. 3 and 4 . A driver of thevehicle 10 and/or a person outside of thevehicle 10 can control expansion or contraction of the thirdexpandable cylinder 234 using control levers and/or button (or similar controls). - In use, the illustrated
boom 20 moves the articulatingnozzle 22 on an end thereof for spraying a fluid therethrough for use in mining as is well known to those skilled in the art. Thevehicle 10 with theboom 20 could also be used in other industries for spraying any fluid. The fluid is supplied to thenozzle 22 from the vehicle throughtubing 36 connected to theboom 20. As illustrated inFIG. 3 , holdinglinks 250 extending from thefourth telescoping arm 34 can be used to hold portions of thetubing 36 adjacent to thefourth telescoping arm 34. Likewise,rod 252 havingtubing sections 254 on ends thereof can extend from thesecond arm 28 and thethird arm 32, with thetubing 36 extending through thetubing sections 254 or with thetubing sections 254 forming a portion of thetubing 36 to support thetubing 36 along the length of theboom 22. - It is to be understood that variations and modifications can be made on the aforementioned structure without departing from the concepts of the present invention.
