WlND-STACKER.

EPEGIFICATION forming part of Letters Patent No. 692,246, dated February 4, 1902.

Application filed March 11, 1901. Serial No. 50,748. (No model.)

To aZZ whom it may concern.-

Be it known that I, EDWARD A. DARST, a citizen of the United States, residing at Eureka, in the county of Woodford and State of Illinois, have invented certain new anduseful Improvements in Wind-Stackers; and I do hereby declare that the following is a full, clear, and exact description of theinvcntion, which will enable others skilled in the art to which it appertains to make and use the same.

This invention pertains toimprovements in straw-stackers as applied to threshing machinery and belongs to that class known as wind-stackers.

The object of my invention is to providea wind-stacker that will build a stack of any reasonable size as perfectly as by the machine known as the web-stacker.

The prevailing difficultywith wind-stackers is that the stacks formed are finished with too large a base and are not of sufficient height. The result of this is that in a few weeks after the stack is built the straw has been reduced to a fiat pile that stock of all kinds can run over and spoil. The fanltlies in the fact that in building the stack the hood on the end of the chute must be placed at such an angle in order to deliver properly that the strawis caused to shoot over the outside edge of the stack upon the ground, thus increasing the base size of the stack and not its height. The trouble arises from an inability to sufficiently extend the chute to allow the delivery-hood to be turned down so as to throw the straw directly down upon the stack at whatever height it may be at work. A further trouble is that the blast through the chute is so strong that thehood must be kept well above the stack in order to prevent the blast making a hole and blowing the straw in all directions. If the Wind is blowing at any time during'the stacking, the straw will be blown away from the hood as it leaves it, thus making it impossible to stack properly. I obviate these difficulties by providing a greater telescoping length for the chute, as will be hereinafter described, and also by the use of a deflector against which the straw may be blown.

In the accompanying drawings, Figure 1 is a side elevation of athreshing-machine, showing my improved device mounted thereon. Fig. 2 is a plan view of a revoluble table which supports the chute. Fig. 3 is a perspective View of a bracket at the top of a brace. Fig. 4 is a face view of the brace mentioned above. Fig. 5isaperspective view of the lower end of said brace, showing connections therefor. Fig. 6 is a top view of a bifurcated pipe attached to the brace described. Fig. 7 is a sectional end view of a supporting-pipe and eyes secured thereto. Fig. 8 is a rear view of a telescoping chute and braced truss therefor. Fig. 9 is a face view of a deflector located in front of the chute. Fig. 10 is aperspective view of a portion of the telescoping chute above referred to.

In the drawings, A indicates a revoluble table mounted in a suitable manner upon one end of a threshing-machine. The usual way of mounting this table is to carry it in rollers a a, as shown in Fig. 2, and the means for turning it consists of a worm b, which meshes with the teeth thereof, saidworm being driven by a shaft 0, having a hand-wheel d or other good means. Usually the table is swung back and forth by a reversing-gear, which moves the chute in an arc ofa circle, as will be understood. By this arrangement the table will support a great weight and may be turned in any direction. The chute B is adapted to rise and fall by means of an elbow, which slips over a similar portion secured to said table. The means for carrying the chute consists of a mast comprising two bars E E, pivoted at their lower ends to projecting supports F, mounted on the table A in the usual manner. A bracket G is secured between the rods and supports the chute, while the said rods E are bent around above said chute and ascend somewhat above it, the ends being bolted together, as shown in Fig. 8. A double truss is arranged on the apparatus thus constructed and consists of two rods H H, bolted at their lower ends to the rods E. Their upper ends are secured to two braces I I, attached to lugs J on the rods E. Rods H are also attached to the arms H at one end and to the arms E at the other, thus forming a complete truss, which serves to brace the said rods E, so that they will withstand a great strain. In Fig. 1 a wheel K is shown between the lugs J, which is connected by a sprocket-chain or other suitable means to a winding mechanism located on the table A, by which to draw the said rods E down toward it on the pivots at e in order to elevate the chute, as will be understood. I have not made an attempt to show the said winding arrangement fully nor describe it at any length, since it is common to all of the machines ofthis character.

A pipe L is attached at one end to the rods E in any good manner and extends at right angles therefrom for some distance and forms a support for the chute B as well as a track for the telescoping portion B thereof. At about the middle of its length the pipe is provided with an upright brace M, which straddles said pipe, as shown in Fig. 4:. The upper end of the brace carries a tie N, one end of which carries the end of a rod 0. The opposite end of the latter is carried in the top of the upper extension of the rods E. Near the outer end of the pipe or track L is a lug P, to which one end of the rod Q is attached, the opposite end thereof being held by the said tie N. A rod R is attached to the upper end of the rods E, and its lower end is connected to the brace M by means of a saddle M, to which said rod is attached, and the same bolt that secures the said brace M.to the pipe L secures said saddle in place. Attached also to the rods E in a suitable manner is a pipe or red S, parallel with L, and Whose opposite end is bifurcated, as shown in Fig. 6, and connected to the lower end of the brace M beneath the pipe L. Though not shown in Fig. 4, said rod S lies between a wheel T and the extremities of M, the said wheel being provided for carrying the chain T or like flexible means, which also runs over a wheel U, journaled in the'region of the rods E. Owing to the enforced reduced scale of Fig. 1, I have indicated the chain T by dotted lines in order to more readily distinguish it from the other lines, but have shown a portion of it in Fig. 10. The chain is used to telescope the chute portion B upon B. As shown in Fig. 1,the said portion B passes over B and its end carries a ring B",to which the chain is attached. The

,outer end of the portion 13 is supported on the pipe L by a roller V on a bail W, secured to the chute in any desired manner or as shown in Fig. 10. Now by turning the wheel U by a crank or other means the portion B will be telescoped upon B,and any desired extension within the limit of the device may be had. It will be noted that the truss composedof the rods L,M,Q,O,and R make a substantial support for the chute no matter what length is used, and said chute by the means described may be swung in any direction or raised or lowered as desired.

The extreme end of the pipe or rod L pivotally supports a deflecting-plate 1 by means of a framework 2, to which said plate is secured. The upper end of the said frame has a cross-arm 3,upon which a T-fitting 4 is carried in a loose manner. The said pipe L is screwed into said fitting,and the said plate is thus permitted to swing at the will of the 0perator. At two opposite sides of the pipe L is an eye 5,and at 6 and 7 are eyes to each of which the end of a wire is attached, as indicated at 8 and 9. Said wires run to the rear of the machine and take a turn around and are attached to wheels 10 and 11. When it is desired to swing the plate on its pivotal support, the crank 12 is turned in a direction to swing the plate into the desired position, as will be understood.

In building a stack the chute is automatically oscillated in the arc of a circle, as previously mentioned. As the stack increases in height the chute must be raised by swinging the truss E II HI J on its pivots e, as before described. The hood is also given a direct downward inclination, so as to land the straw directly upon the top of the stack, said hood being usually operated by means of cables from the operators end of the thresher. However, since I provide the deflector 1 the exact position of the mouth of the hood is not important, since the straw is stopped at the edge of the stack and must remain on top. As the chute swings the deflector swings around the outer edge of the stack and receives the straw. By means of the wires 8 and 9 the said deflector maybe easily manipulated and the stack shaped as desired. The increasing height of the stack necessitates the deflector being drawn closer to the chute, so as to gradually taper the stack toward the top, all of which will be readily understood.

As stated in the objects of my invention,my stacker will build a stack better than the webstacker. It must be understood that when using the latter machine several men are necessary upon the stack, while with the windstacker as I construct it no men are necessary to shape the stack as the straw is delivered upon it. The telescoping portion B of the chute ordinarily can only be drawn out a short distance and hangs and is supported by the portion B. The usual distance the one overlaps the other is about three feet; but with my supporting-track the portions need overlap but two or three inches, or just enough to prevent separation, and I am thereby able to gain a greater extension than ordinarily.

The deflector besides answering the purposes already described also serves as a guide for the operator, who can determine by its ranged to swing in all directions, a support for suspending such chute consisting of a frame or mast pivoted to the support which carries the said chute at its rear end, a truss attached to the top of the said mast and extending forward to support the chute at its forward end, a track supported by said truss, a bail W on the forward extremity of the eX- tensible chute portion, the same beingsupported by the track and adapted to shift thereon, a deflecting-plate pivoted to the forward end of the track as shown, and the wires 8 and 9 attached to the deflector, one above and one below its pivotal point, such wires being carried rearwardly and means for altering the length of the wires for shifting said deflector on its support as set forth.
