HIGH LIFT SIDE-DELIVERY LOADER Filed June 27, 1946 *2Sh6'a'ts-Sheet 2 INVENTOR. Hwy/E4 6f #40 1 67? Patented Apr. 26, i949 UNITED STATES PATENT OFFICE HIGH LIFT SIDE-DELIVERY LOADER Daniel S. Hoover, Mansfield, Ohio Application J une 27, 1946, Serial No. 679,739
3 Claims. 214-132) This invention relates to a high lift side-delivery loader, and has for one of its objects the Production of a simple and eflicient loader for scooping, lifting and dumping a load at a desired location.
A further object of this invention is the production of a simple and efllcient means for bodily shifting the loading scoop and its support vertically of the supporting frame therefor.
Other objects and advantages of this invention will appear throughout the following specification and claims.
In the drawing:
Figure 1 is a side elevational view of the loader;
Figure 2 is a front elevational view certain parts being broken away and certain parts being shown in section;
Figure 3 is a detail perspective view of the scoop arms supporting shaft;
Figure 4 is a top plan view of the loader;
Figure 5 is a bottom plan view of the loader, certain parts being broken away;
Figure 6 is a sectional view taken on line 6-6 of Figure 5.
By referring to the drawing. it will be seen that ill designates a support which is carried by a tractor ll shown in dotted lines. A pair of forwardly extending arms l2 are carried by the yoke and secured at their rear ends. as at i3. Vertical braces H and it are secured at their lower ends I3 and i3", and engage a pivoted inverted ward ends of the arms l2 and a vertical guide frame it is carried near the forward edge of the turn-table i1. This frame It comprises a pair of parallel angle members l3 having side flanges 26. These side flanges 20 are provided with aligned vertical side slots 2 I. The upper end of the frame i8 is braced by the rearwardly extending braces 22 which are anchored at their rear ends to the upper end of the U-shaped member II.
A scoop or excavation tool 23 is supported by a yoke 24 pivoted at 26 and this yoke "26 is rigidly secured to the lower ends of the suspending arms 26. These arms 26 are journaled on the transverse shaft 21 for outward swinging movement. The shaft 21 carries elongated shoes 26 at its ends which slide in the aligned vertical slots 2| of the vertical frame IS. A forwardly extending bracket 26 is carried centrally of the shaft 21 and a hydraulic cylinder 36 is suspended therefrom. The plunger rod ll of the cylinder 36 is secured to the brace rib 32 of the scoop 23, as shown in Figures 1 and 2.
A hydraulic cylinder or jack 33 is secured at one end to the turn-table ll near the rear edge thereof, and at the opposite end to the transverse brace 34 which ties the arms 26 together below the journal thereof. As the cylinder or jack 33 is extended, the shoes 28 slide upwardly in the slots 2i to raise the scoop 23 to the dotted line position indicated as A in Figure 1. As the cylinder or Jack 30 is extended, the shoes 28 will abut against the upper ends of the slots 2i and the arms 26 will be swung further upwardly to raise. the scoop 23 to the position indicated at B in Figure l. The hydraulic cylinder 30 is actuated at that time under the control of the operator from the control station 35 to extend the plunger rod 3! and swing the bucket to a dumping position.
It should be understood that the hydraulic cylinders 30 and 33 are of the conventional type and may be selectively controlled from the control station 35, which control station may be located at any suitable location on the tractor. Furthermore, any suitable lifting means may be substituted for the hydraulic cylinders if desired, without departing from the spirit of the invention.
The frame I0 carries a depending bracket 36 which supports a hydraulic jack' or cylinder 31. The plunger 33 of the jack or cylinder 31 is secured to the links l2 and the jack or cylinder is controlled from the control station 35 for raising and lowering the links I2 which carry the tum-table i1 and the frame is to the desired position.
A hydraulic motor 39 is hung from the turntable I1 and carries a gear 40 which meshes with a gear 4!.
the turn-tablein a selected direction as the motor 33 is operated. The motor 39 is operated from the control station 35. Any suitable motor or operating means may be substituted for the motor 39 if desired.
By rotating the motor 39 the scoop or tool 23 may be faced in the desired direction, since the scoop 23 which is hung on the vertical frame I8 is carried by the turn-table ii. The scoop may be lowered to the desired depth by swinging the links l2 downwardly by operating the jack 31. The scoop is lifted and dumped to the positions A and B as above described.
It should be understood that certain detail changes in the mechanical structure may be employed without departing from the spirit of the invention. so long as such changes fall within the scope of the appended claims.
This gear 40 is keyed to the shaft 62 of the turn-table l1 and is adapted to rotate 3 Having described the invention, what is claimed 1. A loader of the class described comprising a support, a vertical frame, a turn-table rotatably mounted upon said support for turning the vertical frame in a selected direction, a tool-carrying means, said tool-carrying means comprising a hanger slidably pivoted at the upper end of said vertical frame, elevating means, forelevating the hanger to a selected elevated position and then swinging the hanger outwardly to a selected position, said vertical frame having vertical guiding trackways at its upper-end, a transverse shaft carried by said hanger, shoes carrie at the ends of said shaft and traveling in said'trackways, abutments at one end of said trackways against which said shoes abut for limitingthe upward movement of said hanger, and said elevating means constituting means for swinging the hanger outwardly when said shoes abut the ends of said trackways.
2. A loader of the class described comprising a support, a vertical frame, a turn-table rotatably mounted upon said support for turning the vertical frame in a selected direction, a tool-carrying means, said tool-carrying means comprising a hanger slidably pivoted at the upper end of said vertical frame, elevating means for elevating the hanger to a selected elevated position and then swinging the hanger outwardly to a selected position, and means for raising and lowering said 4 tum-table and vertical frame which is carried by the tum-table to regulate the dig ing dep h of said tool.
3. A loader of the class described comprising a support, a vertical frame, a tum-table rotatably mounted upon said support for turning the vertical frame in a selected direction, a tool-carrying means. said tool-carrying means comprising a hanger slidably pivoted at the upper end of said vertical frame, elevating means for elevating the hanger to a selected elevated position and then swinging the hanger outwardly to a selected position, trackways for said hanger, abutment means limiting the upward movement of said hanger, and said elevating means constituting means for swinging the hanger outwardly when said hanger abuts said abutment means.
