' LOGKLIN N. CLARK, OF BRIGHTON, MICHIGAN, ASSIGNOR OF ONE-HALF OF HIS RIGHT TO B. HOWARD LAWSON, OF SAME PLACE.

STRAW-STACKER.

SPECIFICATION forming part of Letters Patent No. 225,344, dated March 9, 1880.

Application filed November 4,1879.

To all whom it may concern Be it known that I, LOOKLIN N. CLARK, of Brighton, Livingston county, State of Michigan, have invented an Improvement in Straw- Stackers, of which the following is a specification.

The nature of this invention relates to certain neyv and useful improvements in the construction of devices for conducting straw from a thrashing-machine; and the invention consists in the peculiar construction and arrangement of parts whereby a sliding frame is provided which can be readily loaded upon the machine for transportation, all as more fully V r 5 hereinafter set. forth.

In the drawings, Figure l is a perspective View, showing the carrier loaded upon the machine and extended for. use in dotted outline. Fig. 2 is a longitudinal vertical section. Fig.

3 is a detail, showing the construction of the sliding joint, and Fig. 4 shows its manner of operation.

In the accompanying drawm s, which form a part of this specification, A represents the body of an ordinary thrashingmachine. To the rear end of this machine, and at the lower corners thereof, is journaled a shaft, B, carrying a driving-pulley, a, upon one end, and a roller, b, between its bearings. One

0 end of a short carrierframe, O, which is provided with a close bottom, as shown, is pivoted to the shaft B, and has journaled near its free end a roller, D,the frame beingleft open from that point to the outer end. Upon the 3 5 ends of the side bars are secured the inwardlyprojecting lugs c, and to the inner faces of the side bars, at the inner ends thereof, are se-' cured the cleats d.

E is a second section of the carrier-frame, 4o constructed substantially like the frame 0, but of such width that it will easily slide between the free ends thereof. The side bars at the rear end of this frame are extended beyond the close bottom thereof a sufficient distance, 5 so as to reach to and abut against the ends of the cleats d, and rest upon the bottom of the first frame, thus forming, when extended, a continuous carrier or way of the same width from end to end, the two sections being held together by means of the lugs 0 and a button, e. To the outer or rear end of this second frame is pivoted a roller, F, over which and the roller 1) passes an endless carrier, G, of

any desired construction.

At or near the rear upper corners of the machine are secured the inclined standards H, in which is journaled a Windlass, I, carrying upon one end suitable means for rotating it, and with a ratchet-wheel and dog. Passing from the Windlass is a suitable rope, J, which is secured to or passes the outer end of the frame E, and by means of this rope and Windlass the frames, when extended, can be elevated to any desired degree of inclination.

We will suppose the device to be loaded upon the machine, as seen in Fig. 1, and it is desired to extend it for the purpose of conducting straw away from the machine. The dog which secures the Windlass is released. The frame resting upon the Windlass is caused to move backward off from the machine by r0 tating the Windlass, or it may be pulled off by hand until .it assumes the position shown in Fig. 4. The shorter sect-ion, being folded up against the rear end of the machine and held in such position by a hook and staple, is then released, when a farther rearward movement causes the shorter frame to assume a horizontal position. a The adjacent ends of the frames falling into position are secured in such position by means of the button 0, thus forming a continuous way or carrier of the same width between its side bars from end to end.

By means of the Windlass and rope the outer end of the frame may be elevated as may be desired, and when it is desired to load the device the sections are released from their engagement, when, by rotating the Windlass, the rope is wound thereon, drawing both frames into their relative places, as shown in Fig. 1. 0

I do notdesire to confine myself to two sections only, as it is evident that it can be extended to three or more sections without departing from the spirit of my invention.

By this manner of construction I produce a carrier or stacker of two or more sections, which are secured together in their extended positions without the use of hinges, while at the same time it is not liable to get out of order, the joint is more rigid, and the device is more easily handled than those now in use.

What I claim as my invention isl. A straw-stacker composed oftwo sections, 0 E, the one section forming a sliding extension to the other, and held in position, when in use, by the lugs 0 and cleats 01, substantially as and for the purposes described.

2. A straw-stacker having, in combination, the frame 0, provided with the roller D, and pivotally secured to the shaft B, and the frame E, slidingly extensible upon the frame 0, both frames being held together by the lugs c, and
