vention willbe apparent from the following description; reference being had to the accompany- -ingdrawing wherein a preferred embodiment" of the present invention isillustrated.

' In the drawings:

from a high level to a IOW'JQVGl'gOIif-IOIB low level to-a high level. vThe. lift. 3.lz.is:tguided by track -means-in .the formof-a lower.-;section 32 andan. uppersection 33. The upper-section 33 .is-carried by a turntable -35 .which preferably can .be turned 90. degrees in either direction from a 45,.

position. shown in Fig.1.; Thus rthe loadto be moved froma highenol" lower level, .canalso be moved in .ahorizontal.direction. The upper section 33 is in. the form of a boom, it being .pivotally mounted as. at 36 on frame work..3-,1 :carried by .the turntable 35.

Referring more indetail to. the drawings, the

lift 3| is in. the form of a shovel;. th'eback of which, when in the.lowermostpositionis engaged I by. the front of the. lowertracksectionfl.

In the preferred embodiment, .the, lower. track section 32 includes horizontally spaced tracks,3/9 and .40. which are formed of heavymetal andare secureditoithe front end'ofthe framejor'ichassis 2| andreinforced by strips 41. When fthefvehicle is -moved'forwardly',"the frontend' of theitiacks 39 3 and 40 will engage the rear of the shovel 3| and force the same forwardly to dig into the material to be removed.

The

track sections

39 and 40 are each C-shaped in cross section, forming channels 43, the open ends of the channels confronting one another. These channels receive the

rollers

45 and 46 of the carriage 48. The carriage 48 includes two side plates 49 which are triangular in shape. Plates 49 each carry a stub shaft and a stub shaft 52 for the

rollers

45 and 46, respectively. Two brackets 53 are carried on the rear side 54 of the bucket type shovel 3| which is hinged by these brackets and pivots 55 to the carriage plates 49. A shaft 56 is fixed to the plates 49 and extends between the same. This shaft 56 carries pulleys 51 and 58, about which are placed cables 59 of the elevating mechanism. The rear side 54 of the shovel 3| carries brackets 6| to which is fastened the ends of the cables 59.

The

tracks

39 and 48, at the bottom are inclined inwardly and downwardly whereby, when the carriage is in the lowermost position, the pivot points 55 are brought relatively close to the ground. It will be seen, particularly from Fig. 1,

that when the vehicle 28 is moved forwardly, the front end of the track frames 39 and 48 will engage the shovel near the bottom thereof and the depth to which the nose of the shovel is permitted to dig into the ground can be governed by the adjustment of the cables 59. The shovel being pivotally attached to the carriage, follows the vehicle rearwardly when the latter is moved rearwardly. When the section of the cable 59, to the left of the pulley 51, is pulled upwardly, the upper part of rear side 54 of the shovel will be pulled rearwardly to lift the front end of the shovel,

and then upon further raising of the cable, the

carriage 48 will be lifted, the

rollers

45 and 46 following the channels 43 to the

track sections

39 and 48.

The boom or upper track section 33 also comprises

tracks

63 and 64 formin channels 65.

, These tracks are formed of the same type of material as

tracks

39 and 40. During the loading operation, that is when the shovel is being filled, tracks 63 and 64 should align vertically, respectively, with

tracks

39 and 48 so that, as the cable 59 is pulled upwardly, the carriage 48 will move from the lower track section to the upper track section. The upper end of

tracks

63 and 64 are closed as at 66 to provide stops for the top rollers 45. When th rollers 45 are in their uppermost position, rollers 46 are opposite rearwardly extending sockets 68 projecting rearwardly from the rearmost side wall of the

tracks

63 and 64. Due to the load of the shovel and its contents, the

lower rolls 46 will move into the rearwardly extending sockets 68. Then when the cables 59 are released slightly, the forward end of the shovel will tip downwardly to unload the contents of the shovel. After the shovel has been emptied, the cables 59 are again pulled upwardly to such an extent that the brackets 18, secured on the rear side 54 of the shovel, will engage the stub shafts 5| whereby the carriage 48 will pivot about the axis of the pulleys 5'! in a counter-clockwise direction pulling the rollers 46 out of the sockets 68. Then when the cables are released, the carriage will drop downwardly in the

tracks

63 and 64.

The top of the boom 33 carries brackets I2 which are spanned by a shaft 13. Pulleys 14 are rotatably mounted on shaft 13 for receiving the cables 59. A frame 16 is carried on the rear side of the turntable 35, as viewed in Fig. 1. The side walls of this frame carry a shaft 11 which supports reels 18, one for each of the cables 59. The shaft 11 is driven preferably by a hydraulic motor through suitable reducing gearing contained within the housing 8|. The driving mechanism for the shaft 11 is also carried by the frame I6. The hydraulic motor is connected by flexible tubing so that it can be operated in any of the posi tions of the turntable 35.

The turntable is actuated preferably hydraulically and to this end there is provided two hydraulic motors in the form of cylinders and rams. A gear 84 is carried on the underside of the turntable which receives a chain 85. One end of the chain is fastened to one of the rams 86 while the other end of the chain is fastened to the other ram 81. By controlling the flow of fluid to the

cylinders

89 and 90, one of the rams moves inwardly while the other moves outwardly and, when so doing, rotates the turntable. It will of course be understood that the motors for the turntable are secured to the chassis 2| and are associated with the turntable only through the chain 85 and gear 84. By manipulating conventional valves, the turntable 35 can be moved 90 degrees in either direction from the position shown in Fig. 1.

As previously stated, the upper track section 33 also functions as a. boom since the

track sections

63 and 64 are pivotally mounted to the bracket frames 31 as at 36. The boom is moved about a horizontal pivot by rams 92 which are associated with hydraulic cylinders 93. The lower end of the cylinders 93 are each carried by a pivot 94 extending upwardly from the turntable 35. The upper ends of the rams 92 are connected by pivots 95 to the rear side of

tracks

63 and 64. The cylinders are connected with a pair of flexible tubes for forcing the rams inwardly and outwardly for raising and lowering the boom.

Preferably the turntable and the track section carried thereby are in a position shown in Fig. 1 during the diggin or collecting operation by the shovel 3|. That is, the carriage 48 is riding within the

tracks

39 and 48 and the

upper tracks

63 and 64 are aligned respectively with

tracks

39 and 40. After the shovel is loaded, the hydraulic motor is actuated to wind the reels 18, causing an upward tipping movement to be imparted to the nose of shovel 3| and thereafter the raising of the carriage 48 and the shovel 3| upwardly, first along

tracks

39 and 40 and then tracks 63 and 64. tracks 63 and 64, the hydraulic rams 86 and 81 can be actuated to turn the boom 33 to the left or right, as desired, and simultaneously, the rams 92 can be actuated to tilt the boom 33. When the carriage reaches its uppermost position and the shovel is over the place where its contents should be dumped, as for example over the truck body which is to convey the material, the hydraulic motor is actuated to slightly release the cables 59 whereby the contents of the shovel 3| will be emptied. The shovel is then again lowered in 5

track sections

63 and 64 as previously explained while if desirable, simultaneously, the boom can 1 be raised to its vertical position and the turntable 35 turns to the position shown in Fig. 1 whereby when the carriage reaches the lower end of the

track sections

63 and 64, said track sections will be aligned with

track sections

39 and 40.

If desirable, the rear wall 54 of the shovel 3| may carry a roller 91 arranged to roll on the forward side of

tracks

39, 40, 63 and 64 while the shovel is being raised and lowered.

After the carriage is being guided by i By reason of the turntable, the tracks and the other mechanism herein described, the vehicle 29 need be moved, only, in the direction necessary to move the shovel forwardly, that is, in the digging direction. In other words, it is not necessary to manipulate the vehicle to a position in which it can load onto a truck since the turntable and boom can be manipulated so that the shovel 3| is brought over the body of the receiving truck.

While the form of mechanism herein shown and described constitutes a preferred form it is to be understood that other forms may be adopted all falling within the scope of the claims which follow.
