Patented Dec. 141, 1915.
Application filed. May 6, 1914. Serial No. 836,723.
To all whom it may concern:
Be it known that I, \VILLIAM E. ZICK, a citizen of the United States, residing at Lakeview, in the county of Montcalm and State of Michigan, have invented new and useful Improvements in Silo-Elevators, of which the following is a specification.
This invention relates to elevators and more particularly to silo elevators.
The principal object of the invention is to provide a weight actuated or elevated elevator of simple and durable construction which shall be inexpensive to manufacture and readily operated and controlled.
Further objects of the invention will appear as the following description is read in connection with the accompanying drawing, which forms a part of this application, and in which Figure l is a side elevation showing the elevator attached to a silo with parts of the chute broken away and the elevator in partly raised position. Fig. 2 is a horizontal section taken on the line 22 of Fig. 1. Fig. 3 is a vertical sectional View taken on the line 3-3 of Fig. 1.
Referring more particularly to the drawing, 1 represents a silo having a plurality of door openings 2 throughout itsheight closed by the doors 3 which are secured in position in any suitable manner. Extending the full length of the silo and covering all of the door openings is a chute -l having vertical cage guiding strips 5 attached to the sides of the chute on the inside thereof. The top of the chute has bridged thereacross suitable supporting bars 6 in which are journaled the cable pulleys 7 over which pass the cables 8. These cables are attached at one end to weights 9 which operate over guiding strips 10 secured to the sides of the chute on the outside thereof. The opposite ends of the cables are connected to a central shaft 11 extending across the spaced cross pieces 12 of the cable. Secured between these cross pieces and depending therefrom are the uprights 13 of the cage whose lower ends are connected between the lower cross pieces 14, as shown. Both of the cross pieces 14: extend beyond the vertical pieces 13 so as to engage upon opposite sides of the guiding strips 5, as shown in Fig. 2, while only one of the cross pieces 12 extends beyond the uprights so as to engage on the forward side of the guiding strips 5, the rear cross piece 12 being cut away. Hinged to this rear cross piece is a brake bar 15 having secured thereto a yoke-shaped operating member 16 which extends downwardly and forwardly for a purpose to be hereinafter described. The ends of the brake bar 15 are provided with friction shoes 17 and the guide engaging ends of the cross piece 12 are also provided with friction shoes 17. The brake bar is normally drawn into engagement with the guiding strips by rela tively heavy spiral springs connected between the brake bar and the uprights 13 so that the relative movement between the brake bar and the cross piece 12 causes both these parts to bind upon opposite sides of the guiding strips and thereby hold the elevator in adjusted position.
Mounted upon the cross pieces 14 and held in position thereon by set screws 18 or other similar devices is a trough or tray 19 having an inclined front edge 20 constituting a shoveling board.
The weights 9 are made sutliciently heavy to lift the cage, its associated trough 20 and the operator when the brake is released. The operator standing in the trough with the brake applied has both hands free to open or close the doors of the silo without having to hang on to ladder rungs, as is customary where ladders are used.
Upon releasing the brake the cage will ascend to the required point where the trough or tray may be filled with ensilage and the door closed. The combined weight of the ensilage, operator and cage are sufficient to overcome the weights and permit the cage to be lowered when the brake is re leased. The yoke-shaped operating member for the brake not only forms a handle for manipulating the same but also produces a guard which prevents the operator from falling out of the cage.
\Vhat is claimed is:-
1. In an elevator, a cage, means for moving the cage, a brake controlling the operation of and arranged transversely of the upper portion of said cage, and means depending from said brake for operating the same, said means constituting a safety In testimony whereof I have affixed my guard. slgnature 1n presence of two Witnesses.
2. In an elevator a brake forcontrolling the movement of the elevator, a U-shaped WVILLIAM ERNEST ZICK' operating member depending from said Witnesses:
brake and havlng a horlzontal portlon ary S. F. I{ENNED Y, ranged transversely of said cage. BLANCHE B. KENNEDY.
Copies of this patent may be obtained for five cents each, by addressing the Commissioner of Patents. Washington, D. G.
