diagrammatic in character, showing the mechanism for coping both ends of the beam. and showing beam numbering cutting and punching mechanisms and the. beam Referring to the accompanying drawings illustrating by wayof example one embodiment of the invention, means are provided for traveling a beam or shape 00 to the cut ting mechanism, and positioning it both longitudinally and transversely preparatory to being notched, coped or otherwise cut, and means are also provided for traveling or transporting the beam away. after the completion of the. operation.

An embodiment of the mechanism will be first described for coping one end of the beam, and at a later point mechanism will be described for coping or otherwise cutting both ends of the beam'in connection with mechanism for traveling and registeringor positioning the beam with respect to the mechanisms for coping or otherwise cutting both ends with a minimum amount of mechanism and a minimum handling. of the beams.

In Fig. 1 of the drawings, means are pro-';

'75 Fig. 17 is a general lay out, somewhat thereof comprising a series of rolls 1, preferably horizontally arranged in a series for feeding the beam 01 longitudinally or endwise. The rollers 1 are mounted in bearings 2 carried upon the frame 3. The shafts of the rollers 1 are provided at one end with beveled gears 1, said gears meshing with beveled gears 5 fixed upon a driven shaft 6, said shaft 6 may be driven continuously or intermittently and also in both directions, as may be foundnecessary in operating the machine. A similar mechanism and arrangement of rollers and driving mechanism are provided on the oppositeside of the coping device for feeding away the beam where it is desired to discharge it by running it forward, or where it is desired to travel and position it with respect to a coping device for operating upon the other end of the beam.

Referring now more particularly to the coping mechanism proper, means are provided for cutting off the flanges and for beveling the web at both sides of the beam from one positioning of the beam. I11 accordance with one feature of the invention also, means are provided for successively -making the various cuts, rapidlyone after the other, while the beam is so positioned.

Means are also provided by the invention for varyingthe relative position or distance between the groups of cutters for beams of different sizes, and in the embodied form,

this is effected by moving or positioning the group or groups of cutters for the flange and web on one side of the beam toward or away from and with respect to those on the other side of the beam. I

'Referring to the illustrated embodiment, a head 11 is mounted in the frame 10 and is held from movement therein by suitable means, such as the pins 12. So far as con-,

"cerns many features of the invention, it could be'utilized for cutting only one side of the beam, but in accordance with other features of the invention, as already indicated, means are provided for cutting both sides of the beam and thus completing the operation, and the mechanism will be so described. The head 11 is conveniently divided horizontally into two parts 13 and 1 1, there being thus provided an opening therebetween through which the web of the beam as passes.

, beam.

' There is a head 15 arranged'contiguously to the head 11, and having likewise two parts 16 and 17 with an opening therebetween through which the web of the beam 00 passes, the construction being like that of the head 11. The head 11 carries a group or groups of cutters for cutting the flanges and web at one side of the beam, and the head 15 carries a group or groups of cutters for cutting the flanges and web on the other side of the Means are provided for moving the head 15 toward and from the head 11 to take beams of different sizes. In the embodied form of such means, the upper part 13 of the head 11 is provided with an internally screw threaded aperture, within which aperture is a sleeve 20, said sleeve having an external screw thread engaging the internal screw thread of the aperture. The upper portion 16 of the head 15 is likewise provided with an internally screw threaded aperture, and the sleeve 20 passes within said aperture and has an external screw thread engaging said internal screw thread of the aperture, but the screw thread on the sleeve 20 engaging with the part 13 is left handed and that engaging with the part 16 is right handed, or vice versa. Thus, when the sleeve 20 is rotated, and the head 11 is held against rotation, the head 15 will be moved toward or from the head 11 to eifect the desired positioning of the two heads for the particular size beam upon which the machine is to operate, and thereby the machine. is adapted to operate upon .beamsof all sizes.

A similar construction is provided at the opposite ends of the heads 11 and 15, the part 14 having a similar screw threaded en gagement with a sleeve 21, the sleeve 21 also being in screw threaded engagement with the part1? of the head 15, shown in Figs. 2, 6 and 8. The screw threads on the sleeve are also reversely cut the same as on the sleeve 20 as already described. the upper and lower halves of the heads .11 and 15,

respectively, are thus kept together.

In accordance with certain features of the invention, as already indicated, the cuts in both the flange and web are made in succession, and preferably not only are the various cuts on one side of the beam so made successively, but the various cuts in. the flanges and web on both sides of the beam are made successively, thus economizing the power required to operate the machine and greatlyreducing the strain placed thereon.

In the embodied form of cutting mechanism,

the part 13 of the head 11 is provided with a stationary cutter 25, having a vertical cutting edge 26 for cutting the flange on the 1 upper side of the web, (referred to Fig. 10).

On the opposite or bottom side of the web, (Figs. 10 and. 11) is a cutter 27 having a cutting edge 28 for cutting the beam flange on the lower side of the web (referred to Fig. 10).

Mounted in the upper part 13 of the head 11 is a reciprocable cutter carrying member 30 provided with a cutter 31. The cutter carrier 30 is reciprocably mounted with its upper edges working beneath the guides 10 and its bottom surface moving upon or with another cutter carrier 35, to be described later (see especially Figs. 2 and 5 The cutter 31 has a cutting edge 32 adapted to cooperate with the cutting edge 26 on cutter 25 to cutthe upper portion of the beam flange, and a cutting edgev 29, adapted to cut the flange immediately above the juncturethereof with the web. Said cutter 31 is also provided with a horizontal cutting edge 33 for cutting the beam web at a bevel from the cut in the flange to the end of the beam (as shown in Figs. 11 and 13). The cutter 31 is preferably given a rake or slant as shown, in Fig. 9 whereby a shearing cut zontal cutting edge 32 in cutting the flanges along the web.

A cutter carrier 35 is reciprocably mounted on the lower part 14 of the head 11, its lower edges sliding on top the guides 1O (Figs. 2 and 5 Said cutter carrier 35 is provided with a cutter 35. Said cutter 35 has a cutting edge 36 adapted to cooperate with the cutting edge 28 of cutter 27 to cut the beam flange below (Figs. 10 and 12). Said cutter 35 has also a horizontally disposed cutting edge 37 adapted to cut the flange away from the web. similarly to the cutting edge 32 of cutter 31 but also adapted to cooperate with the cutting edge 33 of cutter 31 to cut the web of the beam at a bevel from the cut end of the flange to the end of the beam. The same kind of rake or slant is preferably given to cutter 35 as was given to cutter 31 to secure a shearing action, and

the cutter 31 is in advance of the cutter in the direction of their cutting movement, whereby the cuts made along the juncture of the flange and web by cutting edge 29, and across the beam flange by the cutting edges 26 and 32 are made prior to the cuts made along the juncture of the flange and the opposite side of the web by cutting edge 37, and across the flange by the cutting edges 28 and 36. By this means also the cuttingedge 33 is brought into position to cooperate with the cutting edge 37 in the subsequent cutting or trimming of the web.

For the purpose of effecting the cutting movement between the cutting edges 33 and 37, in cutting or trimming the web, the cut ter 35 is mounted for vertical reciprocation in the carrier 35, the actuating mechanism therefor being later described. The head 15 is provided with a similar group of cutters, which need not be described in detail and which are designated by reference numerals to 37*, as required. Thus, means are provided whereby at a single operation the flange is cut off at either side of the web and the web is cut or trimmed, andnot only is this effected for one side of the beam, but both sides thereof atthe one-operation and at one positioning and stopping of the beam.

.Also, these operations are performed in succession and wit-h great rapidity and with but a single stoppage the beam is ready for the neXt operation from the punching or other machine.

In accordance with one feature of the invention, the same means are utilized for both regulating the distance between the heads .11 and 15, and for actuating the cutters during the cutting operation, although so .far as concerns other features of the ,invention, different means may be employed for these purposes. As embodied, a cross head 40 is reciprocably mounted in the frame ofthe machine, said cross head being mounted between guides 10 above and guides 10 below. Shafts 41 and 412 are rotatably .carried bythe cross head 10, but are restrained from longi tudinal move-ment relatively .to, the cross head by suitable means, such as collars43 and nuts 44. The shafts @411 and 12 pass through the sleeves 20 and 2l, splines 45 causing, saidsleeves 21 and 20 to rotate/with the shafts 4:1 and 42, but. permitting the, longitudinal reciprocatory movement of the shafts within the sleeves.

The cross head l0 is connected to thereciprocating cutter carrier 30 and also to the other reciprocating cutter carrier 35", whereby. the cutter carriers 30 and 35 reciprocate upon their bearings in the head 11 to cause the cutters 31 and 35 tocut out the pieces of the flange on either side of the web incoop eration with the cutters 25 and 27 In accordance. with one feature of the invention, means are also provided for-rendering either one-or both the cutters for either side of the flange operative or inoperative, as may be desired, and such meansare preferably embodied in the reciprocatory connections, and are settable either'one way or the other at the option of the operator of the machine. In the embodied form of such means, a wedge or gag 16 is slidably mount ed in the cross head 40 and in, the cutter carrier- 30. i The wedge 416 is provided with a T-shaped head it? working -in. a similar groove in the cross head 4E0. andwith a T- shaped headtS, fitting into a groove or T slot in the cutter carrier 30. Fixed'to the wedge or gag 16 is a rod 50, screw threaded into nut. journaled in a bracket 51-carried upon the machine frame, and provided with a convenient hand. wheel. Thus the gag or wedge 46 1nay he slid backward and forward, thereby, retracting the cutters from the cutting position or moving them forward into cutting position as desired. A

similar controlling device is provided for the other cutter, and the. parts thereof are designated by similar reference numerals and need not be described in detail.

Means are provided for increasing or decreasing the distance between the groups of 62 and 63 upon the shafts 41 and 42.

cutters for both sides of the beam to accom- As embodied the shafts '41 and 42, at the other end thereof are provided with screw threaded portions 62 and 63 respectively. Upon said screw threaded portions is mounted a cross head 64, having apertures therein through which'the shafts 41 and 42 pass, said apertures being internally threaded to engage respectively with thescre'w threads The 1 cross head 64 is connected by a wedge 46 with a cutter carrier and is also connected by awedge 46 with a cutter carrier The head 15 is mountedto slide on guides 10 and 10", the cross head 64 is slidably mounted between the guides 10 above and guides 10 below. The cutter carrier 35 is slidably mounted above guides 10 and cutter carrier 30 is mounted upon cutter carrier 35 and beneath guides 10-, and is adapted to slide with or upon cutter carrier "35". Means are provided for rotating the shafts 41 and 42 together, to regulate the distance betweengthe heads 11 and 15, and

beam are provided, and in the embodied form thereof the reciprocable cross head 40 is pivotally connected to a pitman 70, said pitman being also pivotally connected to a double crank 71 formed in shaft 72, which shaft is mounted upon the machine frame. Means are provided for intermittently operating the mechanism as desired, and in the embodied form' thereof a gear 73 is fixed tothe shaft 72. Meshing with the gear 73 is a pinion 74 upon a shaft 7 5. Fixed to rotate to the shaft 75 is a clutch member 76, said clutch member rotating with but being free to slide upon'the shaft 75. Mounted loosely upon shaft 75 is a gear 77,

meshing with a pinion 86 upon the shaft of a motor 78. Fixed on gear wheel 77 is a "clutch member 79, coiiperating with the movable clutch member 76.

Clutch member 76 is urged into engagement with clutch member 79 by a spring 80, which spring is coiled about shaft 7 between the clutch member 76 and a bearing 81. Formed in the clutch member 76 is a cam groove 82 and ooiiperating therewith is'a pin 83 which is projected into and withdrawn from the cam groove'to control the driving action of engagement and clutch members is effected and controlled by the motor 78 upon the shaft 75. The pin 83 is pressed into the slot by spring 84 and retracted therefrom'by a solenoid 85. In

the present embodiment, the pinion'74' and gear wheel 73 are in the ratio of four to one, although thls is immaterial so far as regards many features of the inventlon.

In the embodied form of 'means for in the head 11, the cutter 35 resting upon the upper end of the bar. The lower end of the bar 90 rests upon a cam 91, which cam is rotatable with but slidable along a shaft 92. The bar 90 and cam 91 are kept together by suitable means, such as a tongue 93 on the bottom of the bar projecting into a groove 94 formed in the face of the cam 91. A similar construction of reciprocable cutter and actuating means-therefor is provided for the other side ofthe machine for making the cut in the other side of the web, and the corresponding parts are indicated by reference numerals .90 to 94, and need not be described in detail. Fixed to the shaft 92 is an arm 99 carryinga weight 100.

Fixed on shaft 92 is a gear 101-, meshing with a pinion 102 on a shaft 103. The ratio of pinion 102 and gear 101 is preferably four to one, as in the case of the pinion 74 and gear 73. Rotatable with but slidable along the shaft'103 is a clutch member 104. Carried loosely upon shaft 102 is a gear 105 driven from a pinion 106 on the shaft of a motor 107. Fixed to the gear 105 is a clutch member 108 adapted to coiiperate with the clutch member 104. The clutch member 104 is urged into engagement with clutch member 108 by spring 109, and the disengagement of the the cam groove 110 in the clutch member 104 and the pin 111 which coiiperates with said groove. The pin 111 is acted on by spring 112 and solenoid 113 in substantially the manner already describedin connection with the clutch mechanism 7 67 9.

, Referring to Fig. 1 of the drawings there is shown at the right a diagrammatic arrangement of circuits whereby the solenoids for the clutch mechanisms are operated from a distance record sheet or other controller sheet 170. The various contacts for the clutch controlling circuits are indicatedby 171 and 172 and a suitable source of power as 173. clutch mechanism may be manually or otherwise operated if desired.

Means are provided for positioning and gaging thebeam or shape both longitudi- It will be understood that the l l l l nally and transversely with reference. to the notching and coping mechanism, and as embodied a guide rail 115 serves to-position the beam transversely. The beam is positioned longitudinally by means of a movable stop, which is movable into and out of the path of travel of the beam, whereby it may position the beam to be operated upon, and then may be moved out of position to permit the beam to be carried away. Said stop is also adjustable to variously position beams of different sizes for notching and coping. As embodied a lever 116 is pivoted at 117 upon the machine frame. The end 118 of lever 116 is enlarged and internally screw threaded to take a screw threaded rod 119, the end of the rod 119 contacting with the end of the beam 07 (Fig. 1), and acting as a stop therefor. A hand wheel 12.0 serves to rotate screw rod 119' to regulate the position of the beam w.

The manner of operation of the mechanism which has already beendescribed in large part, may be summarized as follows:

A beam at is fed into the machine, its transverse position being determined by the guide rail 115, and its longitudinal position being determined by the rod 119. The operation of the cutting devices is determined and controlled in the illustrated and de scribed mechanism by the pins 83 and 111, and these may be controlled manually or automatically as desired or arranged. If the solenoids 85 and 113 are placed in a hand controlled circuit, push buttons could be utilized to operate each asdesired, or the solenoids could be controlled from a perforated distance record sheet or other suitable automatic controlling device. When pin 83 is retracted,clutch member 76 engages clutch member 79, and shafts 75 and 7 2 are started into rotation. The pin 83 being returned into groove 82 cams out the clutch after one rotation of shaft 75.

As the shaft 72 rotates, the connecting rod will travel or reciprocate the groups of cutters which are on either side of the beam 00. Let it be assumed that the cutters in Fig. 2 have taken up the clearance to the right of the beam m and are ready to begin cutting the beam. Cutters 31 and 35 will pass from the position shown in Figs. 2, '9 and 10 to the'positions shown in Figs. 6, 11 and 12. In so doing, one of the cutting edges of the cutter 31 cuts off the flange along the web from the end of the beam, and another cutting edge of cutter 31 has cooperated with the cutter 25 to cut the side of the flange transversely from thecut along the web to outside of the flange. Upon the other side of the web (the lower side in Figs. 10 and 12), a cutting edge-37 of cutter 35 has likewise cut off the flange along the web from the end of the beam, and cutting edge 36 of cutter 35 has cooperated with cutter 27 to make a like transverse cut in the flange from the cut along the web to the outside edge of the flange. This side of the beam is thus cut as shown in Figs. 11 and 12. It will also be understood thatby reason of the cutting edges of the cutter 31 being in advance of the cutting edges of the cutter 35, the cuts are made successively, and the entire power of the machine is thus available for each cut. By reason of the four to one ratio of shafts and 72, the clutch 7 67 9 is thrown out and the reciprocat'ory movement of the cutter is stopped with the cutters in position to cut or trim the web. a r

If it is desired to make the web cut at this time, the pin 111 is actuated to release clutch 104108 for a revolution of shaft 103 thus imparting a quarter revolution to shaft 92. This partial revolution of shaft 92 moves cutter 35 vertically from the position shown in Fig. 12. By such vertical movement of the cutter 35, imparted throughcam 91 and bar90, the cutting edge 37 of cutter 35 and the cutting edge 33 of cutter 31 are moved to the position shown inFigs. 13,14 and 15, thus making a beveled cut in the web of the beam from the cut in the flange to the end of the beam. When the finger 111 again throws out the clutch 104' 108, after a single revolution of the shaft 103, and a quarter revolution of the shaft 92,the weight 100 rotates the shaft 92 back- Wardly and the cutter 35 returns to the position shown in Fig. 12 and is clear of the web of the beam m. Another quarter revolution of shaft 7 2 withdraws the'right hand cutters and brings the left hand cutters forward toward the work. During the first described reciprocatory movement of the groups ofcutters, the movable cutters at the left, (refer to Fig. 2), were moved away from their corresponding stationary cutters and no cutting was effected in that side of the machine.

When clutch 7 67 9 is again released, the rotation of shaft 72 will cause the groups of cutters on the other side-of the beam '(left hand in Fig. 2) to cut the beam, and

the flange of the beam on the opposite side is cut off in like manner to that already described by the cutters on theright hand side of Fig. 2. being again released the corresponding web cut on the left hand side of the beam is also made. If it is desired to throw out any particular cutter, this can be done by the gags or wedges 46, etc.

The adjustments to accommodate beams of different sizes. have already been described and it will be understood that by rotating the shafts 41 and 42 together. the sleeves 20 and 21 will be correspondingly rotated, and said sleeves will consequently pass into or out of the head 11, The head Upon the clutch 104*108.

15 will likewise be traveled along the sleeves 20'and 21, and the cross head 64 will maintain themovable cutters and cutter carriers in proper position with the head 15.

When the cutting of the beam is completed, it can be run backwardly by reversing the rolls 1, or it may be run in a foryvlard direction by swinging up the stop rod In accordance with certain features of the invention, means are provided for simultaneously operating upon both ends of the beam, said means being constructed to accommodate beams of different lengths as well as beams of diiferent sizes. In the embodied form of such means, one beam cuttlng or coping device 130, which may be of like construction and operation as the mechanism already shown and described is provided, same being in operative relation with a series of rollers 131, along which the beams or shapes are adapted to be traveled.

A second beam cutting or coping device 132,

which may likewise be of similar construction and operation as the mechanism herein shown and described is provided. Means are provided for varying the distance between the mechanisms 130 and 132 for beams of different lengths, and as embodied the mechanism or device, 132 is movable along tracks 133 and 134, thereby to be brought into operative relation with one end of beams of varying lengths when the other end of any such beam is in operative relation with the other mechanism or device 130. A driving motor 135 is provided connecting by gearing136 with a shaft 137. The device 132 travels along the shaft 137 in being adjusted in various positions, but the mechanism is driven by the rotation of the shaft in all its positions. At 138 and 139 are indicated means for supplying beams to, and for removingthem from, .the pathway of progressing means 131.

In Fig. 17 of the drawings is shown cooperating mechanism for supplying beams, cutting them into desired lengths, placing identifying marks upon the beams, and for forwarding the beam to coping devicesorpunching devices or to both and for-maintaining a reserve supply of beams when de-' beam maybe cut as desired. The beam is then forwarded along the pathway 145 and may be sent direct to the punching mechanisms 146, 147 and 148, to receive therivet holes for fabrication, or the beams may be sent to thecoping devices and have one or both ends coped and then be forwarded to the punching devices. .A transferring means 150 for transferring the beams from pathway 145 to pathway 151 are provided. In conjunction with pathway 151, a coping device 152 is shown adaptedto cope one end ofithe beam, said device having a longitudinal stop or adjustment 153. After one end of the beam has been coped by this mechanism, the stop 153 may be withdrawn and-the beam run along the pathway 156 past the other coping device or mechanism 154, and the beam may then be brought into operative relation with the stop 155 preparatory to the coping of the beam by the mechanism 154. Upon completion of this operation, the beam may be transferred by the'm'echanism 157 to the pathway 145 and thence to the punching devices 146, etc. In conjunction with the foregoing there is provided transferring and storing devices 158 whereby the output from the mill may be stored preparatory to being either coped or punched for riveting and thus all the mechanisms may be run at full capacity, or any one may be stopped for adjustment or repair without affecting the operation and output of the others.

7 Means are provided by one feature of the invention, for raising and lowering the rolls 1 for beams of different sizes. As embodied said rolls are carried together with their driving shafts and gears 160, upon frame 3 (F ig. 19). Said frame 3 is mounted on suitable raising and lowering devices, such as screw threaded rods 161, passing into internally screw threaded pillars 162. Screw rods 161 are rotated in either direction by bevel-gears 163 meshing with bevel gear 164 on a shaft 165. Thus the rolls are raised and lowered as desired and'the web of the beam centered with respect to the horizontal opening thereforbetween the cutters.
