HAY-STACKE'R.

SPECIFICATION forming part of Letters Patent No. 304,437, dated September 2, 1884.

Application filed June 23, 1884. (No model.) I

To aZZ whom it may concern:

Be it known that we, WILLIAM H. M OLAIN and DAVID J. ADKINS, both of Farmersville, in the county of Livingston and State of Missouri, have invented certain new and useful Improvements in Hay Stackers; and we do hereby declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, which form a part of this specification, and in which Figure 1 is a perspective view of our improved hay-stacker. Fig. 2 is a perspective detail view of the upper portion of the same, and Fig. 3 is a perspective detail view of one of the cross-pieces upon the elevator-belt.

Similar letters of reference indicate corresponding parts in all the figures.

Our invention has relation to that class of hay-stackers in which the hay is carried upon an endless elevator-belt into the stack or mow; and it consists in the improved construction and combination of parts of the same, as hereinafter more fully described and claimed.

111 the accompanying drawings, the letter A indicates the base-frame or skid-frame, which may, if desired, be mounted upon wheels or rollers for easier transportation, and which has two uprights, B B, at its rear end, provided with sheaves Oat their upper ends, forming transverse bearings D near its lower ends, and provided with notches E in their inner edges, having divergently-beveled ends.

F is an inclined board, having transverse bearings G and H at its upper and lower ends, and having a longitudim l groove, I, in its middle, in which groove an endless belt, J, travels, passing over pulleys K upon shafts L and M, journaled in the bearings at the ends of the inclined board. Shaft M in the lower bearings extends outward at its ends, and turns in bearingsN in the forward end of the base-frame, and is provided at one end with a pulley or similar means for connecting it with a motive power for rotating it, the lower end of the inclined board being pivoted upon the shaft at that end. The upper shaft upon the inclined board is provided with a pulley, 0, upon one end, over which passes a short endless belt, P, which" passes over a pulley, Q, upon the end of a board S is secured to the upper end of the inelined board by means of hooks WV, pivoted upon side pieces, X, upon the edges of the in- .clined board, engaging staples Y upon side pieces, Z, upon the short board, the said boards having their meeting ends cut off obliquely,

placing them at an obtuse angle to each other. The endless belts are provided with crosspieces A, of metal, secured at intervals upon them, and the said cross-pieces are bent at their middles to form a groove or recess, B, fitting over the belt, their under side traveling upon the surface of the inclined board, and the ends 0 of the cross-pieces are bent upward, so as to engage with the hay thrown upon the foot of the inclined board and carry it up upon the board, when the belt is revolved. The cross-pieces 13 upon thebelt of the upper short boardare shorter than the cross-pieces upon the belt ofthe inclined board, adapting them to pass within the upturned ends of the latter cross-pieces at the meeting ends of the said boards, where the ends of the said boards are cut away to form a notch or slot, E, but are otherwise of the same shape and construction as the longer cross-pieces.

Two ropes or chains, F, are secured to the up per ends of the side pieces of the inclined board, pass over the sheaves upon the ends of the uprights, and are secured at their lower ends to a windlass, G, journaled in the bearings at the lower ends of the uprights, winding upon the same, serving for the purpose of raising or lowering the elevator-boards; and for the purpose of supporting the said boards in their dilferent positions, a cross piece or bar, H, having beveled edges, may be inserted in a pair of the notches in the inner edges of the uprights.

It will be seen that byconnecting the shaft at the lower end of the elevator-board to a suitable power, causing the elevator-belt to revolve upward upon the upper surface of the said board, the hay which is pitched upon the lower end of the elevator-board will be carried by the pronged cross-pieces upon the belt to the top of the board, and be carried by the extension-board at that end toward the middle of the stack or mow.

The extensioaboard and its belt may be removed when it is desired to bring the hay nearer toward the edge of the stack, and the elevator-board may be raised as the stack increases in height by means of the Windlass, and be supported by the eross-piece adjusted at a suitable height in a pair of the notches in the edges of the uprights.

Having thus described our invention, we claim and desire to secure by Letters Patent of the United States- 1. In a hay-loader having endless elevatorbelts, the pronged eross-pieces having acentral bulge adapted to fit the elevator-belt, and having the ends bent upward to form prongs, as and for the purpose shown and set forth.

2. In a hay-staeker, the combination of the inclined elevator-belt, having cross-pieces having their ends bent upward, fastened upon the elevator-belt, with the carrier-belt, having cross-pieces secured upon it having their ends bent to form prongs, the prongs upon the elevator-belt being wider apart than the carrierprongs, as and for the purpose shown and set forth 3. The combination, in allay-stacker, of the base-frame, the uprights forming bearings near their lower ends, and having notches having inclined ends in their inner edges, the pulleys journaled at the upper ends of the uprights, the Windlass journaled in the bearings in the uprights, the inclined elevator-board forming hearings in its ends, the shafts at the ends of the board, the elevator-belt passing over the said shafts and provided with pronged crosspieces, the extension-board secured removably to the upper" end of the inclined board and formed with bearings at its ends, the shafts journalcd in said bearings, the means for connecting the upper elevator-shaft and the inner carrier-shaft, the carrier-belt passing over the shafts in the extension-board, provided with pronged cross-pieces, and the hoisting-ropes secured to the upper end of the elevator'board and to the Windlass, as and for the purpose shown and set forth.

In testimony that we claim the foregoing as our own we have hereunto afiixed our signatures in presence of two witnesses.
