Specification forming part of Letters Patent- No. 115,810, dated June 13, 1871.

aim e of the Invention.

This invention consists in the construction of the way or track in the form of acrane, and making it adjustableto either an, upwardor downward incline, to adapt the same to the position in which the hay is to be deposited.

General Description. 4

In the drawing, Figure l is an elevation, showing the downward incline of the way or track; Fig. 2, a similar view, showing the upward incline Fig. 3, a perspective View of the fork.

A represents the upright or crane portion, and B the track portion of the elevator. The former has journals a a at the ends, so as to turn .easily in its bearings. The standard is located at any desired position in the timbers of the barn over the mow, and is changeableat pleasure. The track B is hung to the lower end of standard A by a pivot, I), which allows it to turn up or down at any desired angle. A set of holes, 0 c,allows the pivot to be changed so that the track will project more or less, as

circumstances may require. The upper endof the standard and outer end of the track are connected by a chain or rope, G, which is looped through the attachment at one end and hitched up, as shown at d, or otherwise arranged so as to change the angle of the track by taking up q the purpose of receiving the cord or chain that elevates the fork, as will prescntlybe described.

The pulley h rests in a crotch or opening of the car-frame, for the reception of the shank of the fork. The fork consists oftwo claws, E E, which close together, each made up of tines m m, as shown. Each tine is preferably made in a single piece, and th e shanks simply bolted together, as shown at a a. The shank of the lower claw has blanks or washers p p between the tinebars for filling the extra space. The shanks of both claws are pivoted to a bar, G, at some 1 distance apart, the upper end of which is curved as shown ats, and has thehoisting rope or chain H attached thereto. A pawl, I, acted upon by spring K, catches the lower end of the bar G when theclaws are closed, and holds the latter in place. A cord, L, attached to the outer end of the pawl, and passing thence over pulley c" of the upper claw to the hands of the operator, serves to open the fork and discharge the hay.

When thetrack B rests at a downward an gle, as in Fig.1, the hoisting-rope H passes up over the pulley h,- thence up over the pulley g,- thence back over pulley k, and through rollers Z l to the power. In this case, when the load is elevated and suspended to the car, the hoistingrope is slackcd up or'rela'xed, and the car runs down the incline of its own gravity. But when the track rests at an upward incline, as in Fig. 2, the hoisting-rope, after having passed over the pulleys of the car, extends tbrward around pulleyi before passing pulley 7a. In this case, when the power is applied, it first elevates the load to the car, and then draws the car up over the inclined way. The relaxation of the power in this case only allows the empty car to run back to the place of starting again.

I am aware that it is common to run a car on a track for unloading hay; but in all the devices with which I am acquainted the track is fixed and stationary. The great objection to such devices is that the bay has to be dumped in the line of the track, and cannot be distributed.

One principal feature of novelty in my case is the arranging of the track in the form of a crane, which allows the car to be turned in any position to dump its load, by which the dis rrrcn. v

tribution is equal; also, in arranging the track so that it may be turned to an'upward or downward incline, by which the hay may be moved into corners and angles, and above or below timbers or other obstructions. This is of much importance in making the apparatus effective in use.

Claims.

What I claim, and desire to secure by Letters Patent, is 1. The combination of the standard A, track B, and adjusting chain or rope O, the said track being provided with ways ff for the reception of car D, the whole arranged as described, and operating in the manner and for the purpose specified.

2. The standard A, track B, adjusting-chain O, and the crook or'bend s of any hay-fork, the
