GEORGE A. KENNEDY, OF OLENA, OHIO.

HAY-STACKER.

SPECIFICATION forming part of Letters Patent No. 494,336, dated March 28, 1893.

Application filed December 31, 1892. Serial No. 456,880. No modeL) To all whom it may concern:

Be it known that I, GEORGE A. KENNEDY, a citizen of the United States, residing at Olena, in the county of Huron and State of Ohio, have invented certain new and useful Improvements in Hay or Grain Stackers; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying d rawings, and to the letters of reference marked thereon, which form a part of this specification.

My invention relates to that class of hay and straw stackers which employ elevators mounted on a rotary turn-table or platform which is slowly revolved as the stacking progresses, to gradually change the place of deposit in a horizontal direction. It is frequently desirable to stop this motion of the elevator and to discharge in one place only, and this is efiected by throwing the revolving mechanism out of gear. Heretofore the stopping has been done by a man upon the ground acting under the direction of another upon the top of the stack. This, as is at once 0bvious, is very disadvantageous, as it necessi tates the attention of two men, and is objectionable for other reasons.

It is the object of my invention to provide means to enable the horizontal movement of the elevator to be controlled entirely by the man upon the stack, and thus save the time and attention of the man operating the machine upon the ground, besides being more satisfactory, in that the stoppage and starting can be effected immediately, when in the judgment of the man on the stack it is necessary, with out the trouble and delay inci= dent to calling upon another person.

To this end my invention consists in the mechanism having the construction and combination of parts hereinafter specified, and illustrated in the accompanying drawings, in which,

Figure 1, is a side elevation of one construction of stacker to which my invention is applicable. Fig. 2, is an under side view of a portion thereof. Fig. 3, is a section on the line or, a: of Fig. 2.

With the structure of the stacker proper my invention has nothing to do, and the same gether to enable such frame to be compactly folded together when not in use. Said frame 0 is hinged to the turn-table to enable its discharge end to be raised and lowered. The mechanism for rotating the turn-table, briefly set forth, is as follows: Extending cross-wise of the frame A and suitably journaled thereby is a shaft D having a bevel gear d receiving motion from a bevel-gear e driven by suitable connection with the elevator moving mechanism, or any other source of power. Also on said shaft D, is a worm f adapted to drive a worm-wheel g mounted on a shaft G extending at right angles to the shaft D and carrying on its front end a bevel-gear) that meshes with two like gears h, h loosely mounted on a transverse shaft H, to which either is adapted to be clutched to run the shaft in one direction or theother. This shaft H is connected by suitable gearing with the turn-table B and is thus adapted to rotate it slowly and in either direction.

The end of the shaft G near the worm-wheel is journaled in a movable block '5 pivoted to a standard I that depends from one of the cross-bars of the frame A, and to such block is connected one arm of a bell-crank lever J, by a short link j, said bell-crank lever being pivoted to a standard I. To the other arm of said lever is pivotally connected a horizontal, rearwardly extending bar K whose rear end passes through and is guided by a loop k attached to one of the cross-bars of the frame A. Heretofore when it was desired to stop Pivoted to a lateral projection on the bar K, are two bars or links Z which extend toward the standard I and have pivotally connected to their free ends, between them, a link Z, one normally kept in a straight line so as to project the bar K outward and thus keep the worm and worm-wheel in mesh by a spiral springMhaving one end attached to the frame Aand its other end to pins mprojecting from the bar Z. Said pins m are arranged to engage the bars Z on the side away from the spring and operate to prevent the bars being pulled by the spring beyond a point when they are in line, although permitting them to be moved readilyin the opposite direction, to carry the bar K-inward to disengage the Worm- Wheel. Such movement inthe opposite direction is effected by a cord N, likewise connected to pins m, that extend thence 'to a pulley n on the frame A directly in line with the spring M, thence to and through openings at the center of the turn-table, thence to the lower end of the elevator frame, and then along side of the latter to the outer end thereof where it is provided with a ring n to en- I gage any one of the several pins con said frame. Sui-tableg-uide-pulleys or eyes are of course provided for the cord, and in arrangworm and wheel out of gear, the ring n is; simply slippedover one of the pins-c, and to cause them to again mesh it is only requisite to release the cord N by disengaging the ring from the pin.

It will be seen that the rotation of the elevator is wholly under the control of the man upon the stack.

Having thus described my invention, what I claim to be new, and desire to secure by Letters Patent, is-

1. In a stacker having an elevator adapted to be rotated horizontally, the gearing for rotating the same, comprising in part a worm and worm-wheel, the means for moving these into and out of mesh comprising a jointed bar a sliding-bar to which one end of the jointed bar is pivoted a spring to move the latter in one direction and a cord extending to a distant part ofthe machine to move itin'the opposite direction, substantially as described.

2. In a stack-er'having an elevator adapted to be rotated horizontally, in combination with the rotary mechanism, the means to "throw the latter inand out of .gear, comprising a bell crank lever a sliding bar, connect- "ed with the bell crank lever a hinged or jointed bar-connected to the latter, a spring connected with the hinged bar to move it in one direction and :a cord connected to the same to move it in the oppositeidirection, said cord running to theouterend-of theelevator,

substantially as and'for the purpose-described. Intesti-mon'y whereof Ia'ffixmy signature in presence of two witnesses.
