invention, such as will enable. others skilled in the art to which it appertains to-make and use the same.

My invention has for its object to provide a simple and inexpensive, yet efficient and durable device for hoisting ensilage from pit silos and carrying it to remote points for feeding stock; and with this general object in view the invention resides in the novel features of construction and unique combinations of parts to be hereinafter fully described and claimed, the descriptive matter being supplemented by the accompanying drawings which form a part of this specification and in which:

Figure l is a vertical section of a pit silo showing my invention in connection therewith;

Fig. 2 is a perspective View of the device with the hoisting box in readiness to pass onto the elevated tracks; and

Fig. 3 is a perspective View showing the manner in which the box is tilted to discharge its load.

In the drawings above briefly described the numeral 1 designates a pit silo whose top 2 is formed with a preferably rectangular opening 3, said silo extending several feet above the ground. One edge of the opening 3 is flush with one side of the silo as shown.

A derrick frame 4: is provided above the silo, said frame including a pair of standards 5 which incline from the ground to a point above the opening 3 at which point they are connected by a crown bar 6, the intermediate portions of said standards bearing against the silo as seen at 7 to assist in bracing them. Additional bracing of the standards 5 is accomplished by brace bars 8 inclining downwardly therefrom to the top 2. The crown bar 6 carries a block 9 through which a cable 10 passes, one end of said cable being secured to said block at 11 while its other end wound on a Windlass 12 suitably supported by the brace bars 8.

Cable 10 is looped below block 9 and passes through a second block 13 having a Application filed January 10, 1918. Serial 211,205;

sides of the box 17 are provided with out- Wardly projecting rollers 18 located on the vertical. center-lines of said sides and slightly above the centers thereof. These rollers support the box 17 upona pair of elevated rails 19 which lead from the standards 5 of the frame 4, said rollers being guided onto said rails when the box is raised, by means yet to be described.

The rails 19 are located along the upper edges of a pair of parallel openwork fence structures 20 which form the sides of a. feed hunk of any suitable length. The loaded box is pushed along the rails 19 and tilted at intervals to discharge the ensilage into the bunk from which the stock may feed, and in order to assist in the tilting operations, a rope 21 is by preference secured to the box and passed over its top as shown.

In order to guide the rollers 18 onto the tracks 19, a pair of auxiliary tracks 22 are provided, said auxiliary tracks inclining upwardly from the standards 5 to the inner ends of said tracks 19, which ends project beyond said standards and are located above the openings 3, being preferably inclined slightly as shown. The tracks 22 are located in the upward path of the rollers 18 With the result that said rollers will engage their lower sides when the loaded box is I raised as shown in Fig. 2, whereupon con tinued raising of the box will swing the latter rearwardly until it is free of the tracks 22. When this occurs, the box swings in the other direction and is then in position to be pushed along the tracks 19 when hook 14 is released. Turning of the box as it is being raised is prevented by contact with the side of the silo as seen in Fig. 1.

The loaded box having once been supported on the rails 19, is pushed along the latter and tilted when required to scatter its load along the feed bunk (see Fig. 3). The unloaded box is then returned to the silo and by engaging link 15 with hook 14 and operating the Windlass reversely it may be lowered for another amount of ensilage.

The entire device is simple and inexpensive, yet is highly efficient and durable and a great labor saver. Since probably the best results are obtained from the construction shown such construction is preferably used,

1. Thecombinati'on of a vertical shaft a. hoisting; bucket movable: vertically. therein,

a cable for raising said bucket a'pair of main parallel tracks leading laterally from the upper end of said shaft, a lateral roller on each ofi'twoopposite sides ofsaid 'bucket 7 adapted "to roll along said tracks, and a pair of auxiliary tracks inclining downwardly andoutwardly. from the niner ends otsald main tracks, saidcauxiliary tr acksbeing located in the upward: path of said rollers whenthebucketisbelng raised, whereby to swingsaid bucket laterally, whereupon disengagement of, the rollers. from said auxiliary tracks will cause said bucket to swing in the other direction onto said main tracks.

, 2. A structure as specified in claim 1, the

inner; ends of said. main tracks being inclined to cause initial travel of the bucket rollers" onto the same by gravity.

In testimony whereof I have hereunto set my hand in the presence of two subscribing witnesses. I w crimsn REBMAN.
