HAY-STACKER.

SPECIFICATION forming part of Letters Patent No. 314,85'3, dated March 31, 1885.

Application filed November 28, 18H4.

My invention relates to an improvement in Y hay-stackers; and it consists in the combination of a suitable frame-work provided with guiding grooves and pulleys for the elevatingropes to pass over, with the elevator, the hoisting-ropes which are connected thereto. and eX- tending guiding-rails which serve to direct the elevator farther out` upon the frame before it is tilted, as will be more -fully described hereinafter. This invention is an improvement upon that for which I obtained Letters Patent of the United States, No. 304,270, dated August 26, 1884.

The object of my invention is to provide an apparatus whereby the hay can be raked directly upon the elevator, and thus the hay raised by suitable power to the top of the frame, where it is guided by guide-rails,which are located beneath the grooves, over the top of the stack before it is tilted, whereby the hay will be discharged upon the top of the stack and not fall upon the side thereof, thereby remedying a defect which exists in my former invention above referred to.

In the accompanying drawings, Figure l is the side elevation of the hay-stacker embodying my invention. Fig. 2 is avertical section of the same, showing the rake in a tilted position at the top of the frame.

A represents an inclined frame-work of any suitable description, and which will be of a height proportionate to the stack which is to be built. The rear side of this frame, where the stack is to be formed, is made vertical, While the front side, up which the elevator moves, is made inclined, as shown.

In the inner side of each of the side timbers, B, are made suitable grooves,G, in which 5o the guides of the elevator travel, and which grooves are'made curved at their upper ends,

as shown. Upon the outer side of these side timbers at their upper ends are placed the grooved pulleys D, over which the elevatingropes E pass. portion ofthe frame are placed two other pulleys, F, around which the elevating-ropes also pass. To the outer free ends ot' thse ropes the elevating-power is applied. Secured to the frame inside of the side timbers, B, are the inclined guiding-ways G, upon which the .elevator rests as it is moving back and forth.

Where the curve in the groove C begins near the upper ends of the guide-Ways G, I provide metallic guide-extension rails L, which are secured to the side timbers, B, beneath the curved ends of the grooves, and which conform in shape thereto. The extensionrails L project upwardly and rearwardly a little below the outer ends of the grooves and form bearingsfor the elevator to rest upon as it is being guided in the curved ends of the grooves when near the upward limit of its movement. The elevator consists of the cross-bar H, from which project at right angles to each other the two sets of prongs or teeth I. One of the elevating -ropes is attached to the outer set of teeth or prongs, so that when the elevating-power is applied the rst movement of the elevator is to tilt over toward the frame luntil the inner set of teeth or prongs rest'against the inclined guideways.

This elevator is always kept in position by4 means of the two guiding-pins or projections, which project outward from opposite ends of the cross-bar and catch in the guiding-grooves in the inner sides of the timbers B. Vheu this elevator is at the bottom ofthe frame,the outer set of teeth or prongs rest upon the ground, so that the hay-rake can force all of the hay which has been raked up directly upon it, 'and thus prevent any necessity of having to handle it.

Any form of rake that may be preferred may be used; but a windrow-rake having the teeth or prongs projecting in the front of it is prefel-red, for then the rake can be drawn up, so that the prongs or teeth will run in between the prongs or teeth of the elevator. After the hay has been loaded either by a rake or any other suitable means upon the elevator, the elevating-power lis applied to the elevating- Lowerdown upon the vertical IOO ropes, when the elevator tilts backward until its rear set of prongs or ngers strike against the guides. In this position the hay is held, so that it cannot slip off while the elevator is being raised. When the elevator reaches the curved portionof the slot, instead of beginning to tilt over, as was the casein my former invention, and thus partially discharging the hay, the elevator is retained by means of the extension guide-rails L in the position to retain the hay until the eXtreme outer limit of the curvel portions of the slot is reached,

VWhen the elevator is tilted suddenly and all of the hay is emptied over the back of the frame directly upon the top of the stack. This construction prevents the hay from being emptied gradually, and thus being discharged partly upon the side of the stack instead of being discharged entirely upon the top thereof.
