SPECIFICATION forming part or Letters Patent a... 685,600, dated October 1, 1901. Application filed February 1, 1901- Serial No. 45,602. (No model.)

1'0 all whont it may concern:

Be it known that I, HENRY GREEN, a citizen of the United States, residing at Pekin, in the county of Tazewell and State of Illinois,

5 have invented certain new and useful Improvements in Hay-Stackers; and I 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 apo pertains to make and use the same.

This invention relates to improvements in hay rickers or stackers. One of its objects is to provide a construction that will require a minimum of power to operate it.

ficing rigidity or eificiency.

In the accompanying drawings, Figure l is a side view of my improved stacker in its normal position. Fig. 2 is also a side view of my improved stacker, showing its hay-carrier raised to the position for stacking. Fig. 3 is a plan view. Fig. 4: is a front view in part section. Fig. 5 is a perspective view of a 5 shifting support; and Fig. 6 is a perspective view of two separate portions of a supporting means, showing their relative positions.

In the several figures, A indicates the usual runners, which support two standards 0 O 0 near their forward ends by means of a crossbeam 13. A horizontal rod D is carried in the said standards and supports at its ends an A- shaped frame E, which I shall term a lever in the accompanying claims, but refer to it in 5 this specification-as a frame. Between the upper ends of the said frame E are held two uprights G, whose lower ends are held by the said rod D, which passes therethrough. Between the upper extremities of said uprights is carried a pulley F, as shown in Fig. 4. An

arm H is pivotally attached to the said uprights G by suitable straps H, and the opposite end' thereof is pivotally attached to the beam I, as shown in Fig. 1. The latter passes 5 backward between the uprights G, and carries a roller 1 at its lower end, adapted to rest upon the track J, secured to the framework of the stacker, as clearly shown in Fig. 5. The extreme lower ends of the A-frame proj ect below the rod D, upon which they are carried, and by means of arms K are connected A further object is to simplify the construe-- tion of this class of machines without sacri-.

to the lower end of the said beam I, as showii in Figs. 1 and 2. A bail L is pivotally hung from the juncture of the bar H and beam I and pivotally attached at its lower ends to the hay-carrier M. The latter is adjustable for length by the means ordinarily employed and the rear ends thereof are pivoted to supports N, erected on the frame, as shown. Suitable sheaves O are supported on a beam P, located between the supports N, and a rope or cable A-frame E in such manner as to draw the said pulley F toward the sheaves 0 when the rope is pulled. The said carrier is provided with the usual teeth,as shown,and suitably braced, so that it will not become racked or twisted.

solutely necessary in the machine, but are employed as guides for the beam I, so that the great Weight which it is called upon to carry cannot bend or spring it out of shape, all of which will be readily understood.

The operation is as follows: In drawing on the rope the A-frame E is drawn toward the sheave-wheels O, as before intimated and as shown in dotted lines in Fig. 1 and in full lines in Fig. 2. This pulls the arm H, and with it the beam I. This raises the carrier M by means of the bail L, the thrust being that since the A-frame moves on the rod D its lower projecting extremities will be moved in the opposite direction or toward the front of the machine, and since these extremities are connected directly with the beam I the lower end of the latter Will also be moved and will, by means of its roller I, descend this track movement is to apparently lessen the length of the beam I with reference to the fixed length of the A-frame as said beam reaches the vertical position. The idea is to keep the upper ends of the said A-frame' and the beam I in as direct line as possible, so that by depressing the beam as described the above result will be as nearly realized as possible. It will be seen by referring to Fig. 1 that if the said beam remained in the position indicated on the track in full lines its height would be considerably above that shown, and in consequence farther from the upon the track J described. The effect of Q passes over them and the pulley F of the The uprights G, before described, are not abput upon the said beam I. It will be observed direct pull of the A-frame; but by lowering said beam on its track better results are obtained. In full lines in said Fig.1 the beam is of course made to overhang the load asfar as possible, so as to lift it in a direct line. Then after being raised to about the dotted-line position shown it is apparently shortened in the manner and for the purposes described. In Fig. 2 the extreme position has been reached for dumping the hay upon the stack. In this position the carrier M is vertical or slightly beyond the vertical position, being carried there by the downward pull of the A-frame and arm H and bail L, as will be readily seen. The usual weight for returning the carrier to its normal position is indicated in the drawings, one end of its supporting-rope being attached to the carrier and the other to the frame of the stacker. It will be seen that the leverage between the pivotal support of the A-frame and the upper end of said frame is many times greater than between said pivotal support and the ends carrying the arms K. Consequently no loss of power is sufiered, and this is especially evident when considering that the movement of the beam I is downward upon the track J when. raising the load. When the load is delivered and the stacker is assuming its downward position or position of rest, the upward movement of the beam upon its track is of no consequence, as the weight of the haycarrier in moving the A-frame upon its pivot will easily move said beam by means of the said arms K to its upward position upon the track. By this construction of the apparatus and the application of power thereto an advantage is attained without loss of efficiency at other positions. I may vary the construction somewhat and-change the relative positions of .the parts and may incline the track J at other angles than that shown without departing from the spirit of my invention.
