SPECIFICATION forming part of Letters Patent No. 518,637', dated April 24, 1894.

Application filed September 25| 1893. Serial lilo. 486,490. (No model.)

To @ZZ whom t may concern,.-

Be it known that I, ARTHUR VANHOUWEL- ING, a citizen of the United States of America, residing at Olivet, in the county of Mahaska, State of Iowa, have invented an Improvement in Straw-Stackers, of which the followingisa specification.

My object is to produce asimple and durable staokerthat maybe raised or elevated relative to the thrasher in the ordinary manner and be automatically oscillated as required to distribute .the straw in a semi-circle.

To this end my invention consists first, in plvotally mounting a carrier of the ordinary kind upon a frame extended from a thrashlng machine, and in the arrangement and combination upon said frameof means for moving the carrier in the segment of the circle andfor automatically reversing the said movement when it has reached the limit of its stroke in both directions.

My invention consists further in certain o ther details of construction, arrangement and combination of the parts as hereinafter set forth, pointed out in my claims and illustrated in the accompanying drawings, in which- Figure l is a top or plan view of a portion of the thrashing machine, and also a portion of a stacker with parts broken away to show the mechanism for operating the stacker. Fig. 2 is a side elevation of the same showing the carrier in position ready for transportation, in dotted lines. Fig. 3 is a vertical transverse sectional View through the line X X of Fig. 2. Fig. /ls an enlarged detail View showing the device for reversing the motion of the stacker, and Fig. 5 is a detail view showing a modified form of mechanism for performing the same functions.

Referring to the accompanying drawings the reference letter A is used to designate a thrashing machine which is of the ordinary construction.

A2 designates a carrier having endless belts A3 provided with cross pieces A4, arranged to travel ,thereupon and carry straw from the bottom of the stacker to its top. A shaft A5 at the bottom ofthe stacker is provided with belt wheels A3 over which the belts A3 are passed, so that when said shaft is rotated the cross pieces A4 will be moved in the carrier.

that it may be capable of a movement in a` vertical plane relative to said frame.

O designates a frame extended rearwardly from the thrashing machine and having at its outer end a plate C2.

O3 designates a segmental sprocket wheel having a plate C4 formed on its lower end to engage the plate O2 to provide for the rotation of the sprocket wheel relative to the frame O.

G5 is a rod fixed to the sprocket wheel O3 and passed downwardly therefrom and having a sprocket wheel fixed to its lower end for u purposes hereinafter explained. The aforesaid frame B is firmly fixed to the double flange wheel O3 by means of bolts B2 so that the carrier and the sprocket wheel O3 will also be rotated synchronously.

D designates a vertical shaft, mounted in suitable bearings in approximately the central portion of the frame O and having fixed thereto a gear wheel B2 and a sprocket wheel D3, D4 being a chain gearing the sprocket wheels C3 and D3 together. This shaft D is arranged to be driven by a worm gear F fixed to a shaft F2 that is extended horizontally and is provided with a beveled gear wheel F3 at its rear end.

H designates a shaft rotatably mounted in the rear portion of the frame O and adapted to be driven by means of a belt H2 connected With the thrashing machine mechanism.

H3 and H4 are beveled gear wheels loosely mounted upon the shaft H and both normally in engagement with the bevel gear'wheel F3.

J designates a clutch device slidingly but non-rotatably mounted upon the shaft H between the wheels H3 and H4. 'lhis clutch is connected with the lever J2 that is pivoted to IOO K designates downwardly projecting pins fixed to the sprocket wheel C2 at opposite sides thereof to engage the forward end of the lever J2 when the carrier is at either extreme of its movements as required to throw the clutch device J in and out of engagement with the N and N2 and bevel gears N6 and N7 for imparting motion to the shaft A5 of the carrier.

In practical operation it will be seen that when the machine is started the shaft H will be rotated by the belt H2. This motion will be transmitted to the sprocket wheel C2 in such a manner as' to move the carrier in the segment of a circle in the manner hereinbefore indicated. Then when one of the pins K contact with the forward end of the lever J2 it will be obvious that the friction clutch J will be throwninto engagement with the opposite one of the wheels H2 and H4 whereby the motio`n is reversed and the carrier again started to move in the opposite direction. This oscillating movement of the carrier is of course continualduringthe operation of the machine.

I have provided the following means for carrying the carrier when the machine is being transported7 as follows: O designates a truck connected with the frame C by means of a tongue O2and P is a cross piece secured to a frame P2 that is fixed to the aforesaid truck and tongue and the carrier is adapted to rest upon a cross piece P, its forward end being connected with the shaft A5 hereinbefore stated.

In the modified form of gearing shown in Fig. 5 the lever J2 is connected with the shaft H so that when the lever is moved laterally, the shaft H will be moved longitudinally. R designates a bevel gear wheel fixed to the shaft F2, and R2 and R2 are bevel gear wheels fixed to the shaft H and adapted to be brought into engagement with the gear wheel R when the shaft H is moved longitudinally. In this instance the mechanism for reversing the le- Ver is, of course, the same as before shown.

Having thus described my invention, what I claim as new therein, and desire to secure by Letters Patent of the United States therefor, 1s-

l. An improved automatically oscillating straw stacker comprising the following elements to wit; a suitable frame adapted to be attached to athrashing machine, a segmental sprocket wheel rotatably mounted in the outer end of said frame, a frame mounted upon said sprocket, a carrier connected with said frame and capable of a movement in a vertical plane relative thereto, means for voperating said carrier by power derived from the thrashing machine, a vertical shaft also mounted in said frame a sprocket wheel thereon, a chain gearing the said sprocket with the aforesaid segmental shaft, a worm gear in mesh therewith and xed to a suitable shaft, mechanism adapted to rotate said shaft in either direction, two pins projecting from the said segmental sprocket, a lever fulcrumed to a suitable support and adapted to be-engaged by said pins and means whereby a reversal of said lever operates the mechanism for reversing the aforesaid worm gear, and means for operating the device from the thrashing machine,substantially as, and for the purposes, stated.

2. In combination with a thrashing machine, a carrier composed of the parts A2, A3, A4, A5 and A5, frame B having the shaft A5 mounted therein, a frame C fixed to the thrashing machine, a plate C2 mounted in the outer end of the frame C, a segmental gear Wheel C2 having a plate C4 at its under side to mate with the plate C2, means for fixing tli'e frame B to the top of said segmental sprocket C2, a shaft D rotatably mounted in the approximate central portion of the frame C, a gearwheel D2 fixed to said shaft, a sprocket wheel D2 also fixed to said shaft, a chain D4 connecting the wheels C3 and D5, a worm F, a shaft F2 connected therewith, a

beveled gear F3 on the end of said shaft, al

shaft H adapted to be driven by power from the thrashing machine, the gear wheels H2 and H4 rotatably mounted on said shaft H, a clutch J arranged to be placed in engagement with either of the wheels H2 and H4, a lever J2 pivoted in a suitable support, a fork J3 at the rear end of said lever J2, springs J4 interposed upon the shaft I-I between the ends of the fork J2 and bar H5 connecting the said clutch J with the springs J2 for the purposes stated, pins K downwardly projecting from the segmental sprocket wheel C2 to engage the lever J2, as set forth, a shaft C5 extended vertically through the forward end of the frame C, -sprocket wheels N, N, iixed to the opposite ends thereof, a chain N4 for connecting the lower sprocket wheel with the thrashing machine and the gearing devices N5, N6 and N7' for driving the mechanism-of the carrier, all arranged and combined, substantially in the manner set forth, and for the purposes stated.
