HAY-STACKER.

SPECIFICATION forming part of Letters Patent No. 492,059, dated February 21, 189S. Application tied November 8,1892. sain no. 451,331. (No man.)

will enable others skilled in the artto which ity appertains to make and use the same.

This invention relates to hay stackers; and it consists in the novel construction and combination of the parts hereinafter fully described and claimed.

In the drawings: Figure l is a side View of the hay-stacker. Fig. 2 is an end view of the same. Fig. 3 is a detail view of the retaining teeth looking at the opposite side of the machine from the view shown in Fig. 1.

A are the side frames of the conveyer, and A is the distance piece secured horizontally between the two frames.

B B are the rollers of the conveyor, and a are the endless belts or chains which pass around the said rollers and are provided with cross slats c for moving the hay over the surface of the distance piece A. The roller B has a driving pulley b secured on its projecting end outside the frame.

C are the sides of the elevator, the lower ends of which are pivoted to the sides of the conveyer, and C is the distance piece secured between the two sides C.

D D are the rollers of the elevator, and cl are the endless belts or chains which pass around the said rollers and are provided with cross slats d for engaging with the hay and causing it to move up the elevator. The shaft d of the roller D passes through the trunnions which pivot the elevator to the conveyer frames, and E is a toothed pinion secured on the end of the said shaft. A pulley b is also secured on the end of the shaft d, and d2 is'a belt which connects the pulleys b and b', so that the conveyer and elevator are operated simultaneously.

Any equivalent driving devices may be used instead of a belt, such as a drive chain or toothed wheels, for instance.

E is a toothed wheel gearing into the toothed pinion E, and secured upon the shaft e which is journaled in the frame of the conveyer and in the bracket e secured to the said frame. The end of the shaft e is square so that it may be connected to a horse-power or other motor.

F are uprights secured to the ends of the conveyer frames on each side of the elevator, and f are cords or chains which pass through holes in the tops of these uprights. These cords are wound upon the shaft F', which is journaled in the conveyer side frames under the elevator. The free ends of the cords are connected to the elevator sides so that the elevator may be raised or lowered about the shaft d-as a center by turning the shaft F. The ends of the shaft F are square so that handles may be slipped on to turn it, andf is a ratchet wheel secured on the said shaft. A pawl g is pivoted to the bracket e and engages with the ratchet wheel, so that the elevator maybe held in any desired position.

G is an inclined platform leading up to the top of one of the side frames A.

H is a horizontal bar journaled in the bearings h, secured to the side frameA at the top of the platform G, and h are teeth projecting from the said bar. I is a flexible band secured to the said bar, and i is a spring connecting the said band with the frame below the platform, and operating to hold the teeth -in a substantially vertical position.

J is a board hinged to the opposite side d frame A, at the top, by the hingesj, and J is a spring secured to the side frame and holding the said board in a substantially vertical position. The hay-rake with the hay is pushed up the inclined platform and the hay turns the teeth h and the board J to the positions indicated by the dotted lines in Fig. 2. The teeth permit the rake to be moved back down the platform and retain the hay on the conveyer, and the board J re-assumes its vertical position and insures the hay being evenly distributed over the elevator. The motion of the driving devices carries the hay along the conveyer and up the elevator, and forms it into a stack.

1. In a hay-stacker, the combination, with a conveyer, and an inclined platform leading up to it, of a bar journaled at the top of the said platform and provided with teeth, and a IOO 3. In zt hay-stacker, the combination, with l a. oonveyer, of a, bar journeled at the top of l one of the side frames and provided with teeth and t springopereting to hold the said teeth in their raised position, and zt board hinged to the opposite side frame and provided with a, spring operating to hold it in its raised position, whereby the hay is retained on the eonveyer and distributed evenly over its surface, substantially es set forth.

In testimony whereof I afix my signature in presence of two witnesses.
