in the drawings, the wheels 15* have. their flangesturned outwardlyso as to. rotate. adjacent the:-
spaced upstandin members l3.
A boom designated generally I'll comprising a pair of spacediparalle'll channels l:8, held in; spaced.
parallel rela-tion by crossibraces I?! so that the.
a will be, more fully hereinafter explained.
Extendingupwardly from the-boom H near its outer? endzis a: pairv of longitudinally spaced earsw supporting; a pivot pin 31" which extends par-- allel; to the longitudinal axis of the boom and. pivotally support's a yoke 32- in which a bucket,
retracting pulley:- 33- is rotatably supported. As.
illustrated in Figured this pulley is adapted tovbel rotated upwardly through anarc-of one hundred? eighty degrees so as-to: be operable from either sideofzthevboomi Mounted attheextremeouter endof'. the boom;
H for rotation about, an axis: extending; trans versely of thelongitudinah axis of; the boom ista: pulley34' over which; a carriage" advancing cable; 3.5isltrained; One end of this cabl is attached tot the; eye; 26; of' the. carriage. 2i while. its opposite end is trained over' an idler pulley 3%- carried by the boom near its opposite end. This cable then extends downwardly and is: adapted to be which the fianged wheel-sli rotata As=illustrated 5 5 wound upon a winding drum 31 mounted for nected. This trench jack 39 is preferably firmly secured adjacent the back wall of the bin or car to be unloaded, and trained over the pulley 4| and the bucket retracting pulley 32 is a cable 42, one end of which is attached to the rear side of a drag bucket 43, while the opposite end of said cable is trained over an idler pulley 44 and thence downwardly to be wound upon a winding drum 45.
The drum 45 is mounted to rotate in a suitable bracket 46 carried by the base l and it will be seen that when the cable 42 is wound thereon, pull will be exerted on the bucket 43 to move it toward the back of the bin or car in which the device is being used.
A bucket advancing cable 41 is attached to the bail 48 of the drag bucket 43 and is trained over the pulley 21 from whence it passes longitudinally along the underside of the boom to an idler pulley 49 mounted between the standards I I at the forward end of the base Ill. The cable 41 then passes downwardly to a winding drum 50 mounted for rotation in a pair of spaced brackets carried by the base l0. It will thus be seen that when the cable 41 is wound upon the drum 50 the drag bucket 43 will be moved toward the boom and away from the back wall of the bin or car.
A prime mover 52 is mounted on the base In and has driving connection with a gear train 53 through the medium of a drive belt 54. The gear train is connected through a series of clutches to the drive shafts of the drums 31, 45 and 50 controlled respectively by clutch levers 55, 56 and 51 that it extends transversely across the open front side of the bin in which the material to be unloaded is confined. The lever 55 is then manipulated to set the drum 31 in operation to wind the cable thereon and hence mov the carriage 2| to the desired position in front of the bin. Having thus positioned the carriage and the bucket advancing and sustaining roller 21 to its proper place in front of the bin, the hand lever 56 is manipulated to cause the drum to be driven so as to wind the cable 42 thereon. The taking up of the cable 42 causes the bucket 43 to be moved toward the rear wall of the bin over the material contained therein, and when the bucket has been moved to a point near the rear wall of the bin or car, rotation of the drum 45 is stopped and the lever 51 is then manipulated to set the drum into motion to wind the cable 41 thereon and cause the bucket 43 to scrape the contents of the bin toward the front thereof, simultaneously fill-.
of the boom I! and toward the standards When the bucket has achieved the desired position its contents may be discharged and the operation repeated until the entire contents of the bin has been removed.
While in'the foregoing there has been shown and described the preferred embodiment of this invention it is to be understood that minor changes in the details of construction, combination and arrangement of parts may be resorted to without departing from the spirit and scope of the invention as claimed.
