This invention relates to a loading device which is particularly designed to provide a device which installed on a truck or other vehicle will permit the operator thereof to load his truck without the use of additional equipment.
The use of such a load cuts loading and digging costs since it eliminates the need of extra equipment. It will have time since trucks so equipped will not have to stand in line to be filled.
An object of the invention is to provide a loader that is durable in use operated by hydraulic action having a minimum of moving parts which will perform its tasks in an expeditious and efib cient manner and can be installed on any type of conventional truck or other vehicle in use at the present time.
With the above and other objects and advantages in view the invention consists of the novel details of construction, arrangement and combination of parts more fully hereinafter described, claimed and illustrated in the accompanying drawings in which:
Figure 1 is an elevational view of an embodiment of the invention installed on a dump truck;
Figure 2 is a front view of the loader per se;
Figure 3 is a top plan view thereof;
Figure 4 is a sectional view on the line H of Figure 1;

Figure 10 is a sectional view on the line [IL-Ill of Figure 9;.
Figure 11 is a sectional view on the line lI-l l of Figure 9;
Figure 12 is a sectional view on the line l2-i2 of Figure 9;
Figures 13 to 17 inclusive are diagrammatical views of the loader in operation; and
Figure 18 is a diagrammatical view of the hydraulic control system.
Referring more in detail to the drawing the reference numeral 20 designates a dump or similar truck to which the loader embodying the invention is attached.
The means for mounting the loader on the truck comprises a rear saddle 22 as best shown in Figure 4 which comprises the top bar 24 hav-. ing the straight portion 26 and inclined portions 8 Claims. (Cl. 214-78) 28 which are bent downward at 30 to form the aligned vertical portions 32.
i The straight portion 25 is secured at 34 to the upper longitudinal edge of the truck frame channel members 36 and angular members 38 are secured by welding or the like at 40 to the straight portion 26, at 42 to the vertical sides of the members 35, and at 44 to the lower end of the portions 32.
Secured to the members 38 at their point of angularity 46 by fasteners 48 is the tubular tie rod 50 and the saddle 22 is positioned or mounted on the truck directly below the rearmost transverse edge of the cab 52 of the truck 20.
Mounted forwardly of the saddle 22 at the rear edge of the front fenders 54 of the truck 20 is the under frame 56 which is best seen in Figure 5 and this frame comprises the horizontally disposed beam 58 having the vertical members Bil se cured at 62 to the beam 58 and at 64 to the truck frame 36. A plate underlies the frame 36 and secured thereto at 68 to the member Gil and at 10 to the frame 36 and a short vertical memberspaced "from in parallel relation with the members is secured by welding or the like at 12 to the beam 58 and at H by welding or the like to the plate 56.
Secured to the outer opposite ends of the beam 58 and to the portions 32 at 16 and i8 respectively are the inverted T-bars which form the side frames and supports for the loader.
Secured by welding to the bars 80 adjacent the ends of the beam 58 are the arcuate arms 82 which are secured by welding or the like at 84 to the vertical bar 86 which is secured at 88 to the bars 80. Secured in contact with the bars 80 by the same securing means for the bars are the arms 90 and spacers 92 are positioned intermediate the arms 90 and the bars 80 to compensate for the base of the bars and to align the arms 90. At the forward end of the arms 90 a shaft 94 journaled in the arms and in the bars 80 pivotally mount the A frame 95 thereon and a triangular brace 98 secured to the forward end of the bars 80 act as stops for the lifting arms Hill for the A frame 96 as well as stops llll secured by welding to the members 82.
Pivoted on the arms 90 at I02 are the hydraulic units comprising cylinders llll having the pistons I06 therein which are connected at I08 to the plate H0 welded to the arms illll adjacent the pivot 94 and the cylinders Hi4 cause the actuation of the arms through the proper manipulation of controls mounted in the cab- 50 at a convenient l cation to the driver thereof.
aaico 3 Secured to the arms I adjacent the plate III are the brackets 2 to which are connected at III the hydraulic units or rams II which are connected at III to the triangular plates I20 secured to the second arms I22 which are pivoted at I24 to the lifting arms Ill and a bearing plate I26 is mounted on the pivot I24 intermediate of the arms I00 and I22. A semicircular flange I28 connected to the lifting arm I00 is spaced from and follows the contour of the plate I20. A bearing I" is secured by welding in the arm I00 and retained therein by circular rings or braces I32 secured interiorly of the arms I00 and sectional nuts I are secured on the pivot I24 by bolts I26. The pivot 04 is provided with a lubrication fitting Ill in the arms I00 and a bucket, I40 is secured to the free ends of the second arms I22 by fasteners I42 and tubular spacing members 4 A-frame, saddles on'said truck frame, side frames connected to the opposite ends of said saddles Ill are secured to the free ends of the arms I00.
Secured to the rear of the cab 50 on the dump body of the truck are T-shaped supports I46 on which the second arms I22 rest when the loader is in position for movement of the truck.
The loader operates by hydraulic pressure using oil and the arrangement for the operation of the loader is shown in Figure 18 wherein there is shown the reservoir tank I48 connected to the pump I50 which in turn is connected to control valves I52 and I5, valve I52 being for the operation of rams IIS and valve I54 for the operation of cylinders I00.
Thus when in operation the loader is driven into a pile of dirt or other material to be moved and the bucket is pushed into the dirt to be filled and then elevated to dump the contents thereof into the truck. a
Thus the driver can load his truck and after the loading thereof position the loader in carrying position and move the truck to further dump the contents thereof at any desired locatiom It is believed that the operation and construction of the invention will be apparent to those skilled in the art and it is to be understood that changes in the details of construction, operation and arrangement of parts may be resorted to provided they fall within the spirit of the invention and the scope of the appended claims.
