shown in the drawings, described and claimed,

it being understood that changes in the precise embodiment of the invention may be made within the scope of what is claimed without departing from the spirit 0 In the drawings:

Figure 15 is a side elevation of the lower end of one of the control. levers and its holding means.

Referring to the drawings, thenumeral 1 designates the horizontal frame which is preferably U-shaped as shown in Figure 11, and is adapted to receive therein a tractor in a v position where its rear axle housing 2 will be received within the U-shaped brackets 3 for attaching the frame to the tractor. The rear axle housing 2 is provided with the usual differential casing 4, which has therein a conventional diflerential which also drives the rearwardly extending shaft 5. Mounted on a platform 6 is a conventional. form of hoisting mechanism having drums 10, 11, 12 and 13. The hoisting mechanism is provided a with abevelled gear 14.. which is driven by the bevelled drive gear 15 carried by the rearwardly extending shaft 5. Therefore it will be seen that power for driving the hoisting device is obtained from the tractor drive 1 mechanism, which may beof any construction or. if so desired, any kind of a hoisting device may be used, even a stationary type, and applicant doesnot limit himself in this particular, or to the specific construction of the hoisting device. The hoisting drums 10, 11, 12 and 13 are controlled by conventional clutch members 16, 17 18 and 19 of the cam type shown in Figure 11, whereby any of the drums may be selectively locked to rotate 35;;with the shaft 20 of the hoisting device.

Extending upwardly from the forward end of the frame 1 is a mast 21 which is braced by the rearwardly diverging bars 22, and has its lower end provided with a turn-table 23,

by any pulls on the cables incident to the rotation of the mast. Pivotally connected at 26 to the turntable are forwardly diverging arms 27, to the ends of which are connected rearwardly extending cables 28. .The arms 27 are slidably mounted on the arcuate rod 29 as clearly shown in figure 3 and interposed between the arms 27 and lugs 30, carried by the turn-table 23, are coiled springs 31, which springs yield at the ends of the movement of the turntable for relieving the strain on the cables 28. The cables 28 extend rearwardly and terminate in pulleys 32, through which extend the cables 33, one of the ends of which cables is anchored at 34 to the frame 1, and the other ends extend rearwardly and The around. the drums 10 and 13, therefore it will be seen that the operator, while manipulating the levers 35 for controlling the clutches 16 and 19, may rotate the turn-table to any position desired.

Pivoted to the frame 1, adjacent the turntable 23 is a brake lever 36 which cooperates with the periphery of the turn-table 23 and is controlled by a rearwardly extending cable 37, which is connected to a conventional form of lever 38 adjacent the rear end of the frame,

therefore it will be seen that the operator may immediately stop the rotation of the turn-table and still allow a slight movement of the cables 28 incident to the springs 31. The drum clutches 17 and 18 are controlled by levers 39 and 40 within easy reach of the operator on the tractor seat 41.

Pivoted at 42 to the turn-table 23 is an upwardly and forwardly extending boom 43,

the upper end of which'is in turn pivoted at 44 to the fork frame 45. Connected to the fork frame 45 below the pivotal point 44 spaced blocks 46, through which a cable 47 extends, and which cable also'extends over the pulley 48 carried by the pivoted mast head 49. One end of the cable 47 is anchored at 49a to the mast head while the lead end 50 of the cable extends rearwardly and over pulley 51 and into the mast 21. Connected to the upper end of the fork frame, above the pivotal point 44 is a conventional form of block 52, over which the cable 53 extends, and

ext/ends downwardly through the mast 21,

and thence over the pulley 55 carried by the supporting spider of the turn-table 23, and thence outwardly and rearwardly over the pulley 56 and around the drum 12. Therefore it will be seen that by manipulating the drum 12, the upper end of the pivoted frame 45 may be moved.

The lead end 50 of the cable 47 which extends downwardly through the 21 extends over the pulley 57, similarly mounted to the pulley 55, and thence outwardly and rearwardly over the pulley 58 to the drum 11, therefore it will be seen that by manipulating the drums 11 and 14, the forked frame 45 may be moved to various angle positions in a vertical longitudinal plane for the shovelling and discharging operations. It will also be noted that the cables 53 and 47 have'their lead ends 50 and 5% extending downwardly through the mast adjacent its axis, thereby obviating imparting pulls on the cables upon rotation of the turn table 23. v

The fork frame 45 is substantially U- shaped and has pivotally mounted in bearings of its spaced arms 60, the pintles 61 of the fork shaft 62. The shaft 62 adjacent the pintles 61 is provided with pulleys 68, over which extend in opposite directions cables 64, and which cables extend rearwardly through pulleys 65 at the pivotal point of the frame 45, and thence downwardly and inwardly over pulleys 66 carried by the-boom, and thence through pulleys 66a and 66?) carried by the turntable, and have their ends anchored at 67 to the pivoted arms 27 carried by the turn-table, therefore it will be seen that by manipulating the cables 28 with the brake 36 holding the-turn table, the fork may be manipulated for adjusting the same to various angles during the shovelling operation.

Referring to- Figure 7 the fork tines 69 is shown in position for piercing a stack of material, therefore in adjusting the device, the parts are placed in position as shown in said figure with the latch 68 engaging the end of the latch bar 690 as shown in Figure 10 for causing a pivotal movement of the fork upon rocking the frame 45 for the shovelling operation, and the latch bar is released and allowed to move longitudinally during a discharging operation as shown when the parts are in the position of Figure5. The latching bar 690 is slidably mounted in a pivotally mounted bearing sleeve 70, reference being had to Figures 8 to 10, and which sleeve is carried by a pivoted bar 71 carried by the boom frame 43. Pivoted to opposite sides of the latch sleeve is a U-shaped member 70a which arches the rear headed end 69a ofa latch bar 690, and holds the latch bar against longitudinal movement. The

U-shaped member 70a is normally held in arched relation to the headed end 69a by means of a coiled spring 7 OZ), 'The forward end of the U-shapedmember 70a is provided with an arm 700, to which is connected a downwardly extending cable 7 2. The cable 7 2 extends downwardly over the pulley 7 3, and thence over pulleys'74 and pulley 66?) which is a double pulley to the lever 27 for,

releasing the latch for discharge operation.

It willbe noted that when the latch bar69c is released by'the latch, the fork may be con ,trolled at will-through the'manipulation of the cables 64-and the device relatched by manipulating the cable 7 2 which controls the latch. Afterthe fork: swings downwardly for the discharge operation, frame 45, as well as the fork as a whole, through the control cables 64, are manipulated for returning the fork to shovelling position and for latching purposes. I

To push the material from the fork when the fork reaches the discharge position as shown in Figure 5, a vertically disposed plate 77 is provided, the ends of which are pro-- vided with downwardly and upwardly extending arms 78, which arch the under sides of the end tines 69 and connected to the arms 7 8 are rearwardly extending arms 79, the rear ends of which are pivoted at 80 to links '81, which links are in turn pivoted at 82 to the arms 60 of the frame 45. When the fork is moved to a discharge position, the links 81 approach positions in alinement with the arms 7 9, thereby forcing the plate 77 outwardly for pushing the material from the fork. When-the fork approaches the loading position as shown in Figure 7, the arms 7 9 are folded towards registering positions in relation to the links 81 incident to the latch holding the latch bar 690, which cause an upwardmovement of the out end of the will be seen that the'p'ivotal movement of'the.

fork will be limited in its movement in either direction. It isv obvious that the shock incident to the fork assuming the position shown in Figure 5 would be relatively great, and to overcome and takeup this shock, the pivoted arms 86 are formed from stationary inner sections 88 having slidably. mounted thereon the outer slotted sections 89, to opposite sides of which are anchored plates 90 and spacing strips or U-shaped members 91, the transverse portions of which cooperate with the strips 92 carried by the members 89 for limiting the outward movement thereof.

Anchored to one of the plates 90 at 93 are coiled springs 94, the other ends of which are anchored at 95 to the pivoted sections 88 of the arms, therefore it will be seen that when the members 84 carried by the fork arms83 engage the ends of the slots 85, the springs 90 will be stretched, thereby absorbing the shock, and when the fork is returned to shovelling position, the shoulders 96 of the arm members 88 will limit the inward movement thereof.

Although the device is described inconnection with a fork, it is obvious that the same mechanism may be utilized for manipulating a shovel for shovelling or excavating purposes, therefore applicant does not I limit himself in this particular.

controlof the operator at all times.

From the above it will be seen that a loading device is provided which is simple in "construction, the parts reduced to a minimum, and one-wherein the position of the fork and the movement of the fork is under the It will also be seen that an automatic fork cleaner is provided, which, when the fork is moved to loading position, will be automatically moved inwardly, and whenmoved todischarge position, will be automatically moved outwardly for discharging the material from the fork, for instance into a vehicle.
