METHOD OF AND APPARATUS FOR S TACKING STRAW- Specification of Letters Patent.

Patented Jan. 23, 1906.

Application filed November 30, 190d. Serial No. 234,862,

1'0 ctl whom it may concern:

Be it known that we, JOHN A. GUNN, residing at Des Moines, in the county of Polk, and JOSEPH J. MCBRIDE, residing at Laporte, in the county of Blackhawk, State of Iowa, citi- Zens of the United States, have invented a certain new and useful Method of and Apparatus for Stacking Straw, of which the following is a specification.

The object of our invention is to provide an improved method of stacking straw whereby an ordinary wind-stacker may be used for stacking straw and a stack built thereby of uniform size and shape and adapted to shed water without the necessity of having men on the stack itself while the stack is being made; and our object is, further, to provide an apparatus of simple, durable, and inexpensive construction composed of portable screen-sections that may be readily, quickly, and easily folded into compact form for convenience in transportation. I

Our invention consists in the method of forming a straw-stack and in the construction of the apparatus for carrying out the method, as hereinafter more fully set forth,

' pointed out in our claims, and illustrated in the accompanying drawings, in which Figure 1 shows a perspective view of one side and end of the stack-former set up as required for use. Fig. 2 shows a vertical central sectional view of the stack-former set up as required for use with a partially-formed stack therein and a wind-stacker in position for depositing straw upon the stack. Fig. 3 shows a central longitudinal sectional view of one of the staclcforming sections in its folded position. Fig. 4 shows an edge view of same. Fig. 5 shows an edge view of a complete section in position ready for use. Fig. 6 shows a detail perspective view of a portion of one of the stack-forming sections to illustrate the means for locking the upper section member in its extended position. Fig. 7 shows a vertical sectional view of a screen and a straw-stack adjacent thereto, and Fig. 8 shows a view of a stack with the screen removed.

Referring to the accompanying drawings, it is noted that the stack-former is composed of a number of stack-forming sections, each independently supported in its own base upon the surface upon which the stack is to be formed. Each section comprises a base composed of alight frame 10, preferably braced by a cross-piece 11 and bracerods 12. To one end of the base we have pivoted an upright section member 13, provided with bracerods 1.4 and covered by screen 15 of wire-netting. Pivoted to the upper end of the section member 13 is a top or folding section member 16, provided with brace-rods 17 and covered by a wire-netting 18. Te have provided means for supporting the section member 18 in an upright position by means of the braces 19, pivoted at one end to the base 10 and at the other end to the section member 13 and provided with elbow-joints at their central portions. These braces 19 firmly support the section member 13 in their upright position, and yet when the elbow-joints 20 are broken the sec tion member 13 may fold downwardly on top of and parallel with the base 10. Te have also provided means whereby the upper section member 16 may be moved from its folded position to the position indicated in Fig. 1, as follows: 21 indicates a lever fulcrumed to one of the uprights of the section member 13. Pivoted to one end of the lever 2 1 is a rod 22,which is also pivoted to the upper section member 16 on one side of its pivotal center. On the other side of the fulcrumpoint of the lever 21 is a rod 23, pivoted to the lever 21 and to the upper section member 16 on the side of its pivotal point opposite from the point where the' rod 22 is pivoted. The end of the lever 21 beyond the point where the rod 23 is pivoted is formed into a handle 24. Obviously by manipulating this handle the upper section member 16 may be moved from a position parallel with the lower section member 13 to the position shown in Fig. 1. The means for raising and lowering the upper section member is connected with one side only of said upper section member, and in order to secure the upper section member firmly in pivotal point of the lever 27, and when the handle portion is at its lower limit of movement the loop 26 will be locked in position close to the pivotal point of the lever 27, thus firmly supporting the side of the upper section member opposite from the side to which the lever 21 is pivoted. We have also provided means for locking the lever 21 as follows: Pivoted to the lever 21 is a rod 29, and on the adjacent portion of thelower section member 13 is a number of loops 30, designed to receive the end of the rod 29. When the section is folded for transportation, as shown in Fig. 4, the parts may be firmly locked together by means of ahook 31, pivoted to one end of base 10 and inserted in an eye 32, fixed to the adjacent portion of the upper section member 16. The upper section members, which are designed for use at the corner of a stack, are made substantially of triangular form, as clearly shown in Fig. 1, so that the two adjacent sections may stand with their adjoining edges close together.

By constructing a stack-former of a number of independent sections, each of which is self-supported, we avoid the necessity of using stakes or other means for fastening each section to the ground. Furthermore, by using more or less sections the size and shape of the stack may be varied at will. In use we prefer to erect the stack-former of sections arranged at the sides and one end only of the space upon which the stack is to be formed, and through the open end of the stackformer the wind-stacker is introduced. In erecting the stack-former two men can easily and conveniently carry each section to position. Then the base is unfolded and placed upon the ground and the upper and lower section members are placed in an upright position. Then by manipulating the lever 21 the upper section maybe elevated to position. The weight of the base portion 10 is suflicient to counterbalance the weight of the upper section member, so that the device will not tilt inwardly. After the stack is completed the sections may be quickly and easily removed by first folding the lower section member over the base and then lowering the upper section member to position on top of the lower one, or each section may be jointly withdrawn from position adjacent to the stack, so that the upper section member may be lowered first, and then the lower section member, together with the upper section member, may be folded over the base. The various sections comprising the stack-former may be easily and quickly loaded upon a wagon or suitable vehicle and transported from place to place with a threshing apparatus.

In practicing our improved method of stacking with the use of our improved apparatus we first erect the stack-former about the spot upon which the stack is to be formed.

' An ordinary wind-stacker is then introduced through the open end of the stack-former and a quantity of straw is first piled at or near the center of the place upon which the stack is to be formed. Then the trunk of the wind-stacker is placed relatively close to the quantity of straw at the center of the stack and arranged to discharge air and straw in a nearly horizontal direction toward the screen. In this connection it is to be understood that blades of straw usually arrange themselves longitudinally of the wind-stacker, and hence by discharging the blast of air laden with straw from the wind-stacker in a nearly horizontal direction the straw is deposited upon the stack in the same way in which it is dischargedthat is, with the straws in nearly a horizontal position. After a quantity of straw is first piled at or near the center of the stack the operator moves the wind-stacker around within the stack-former to build up the stack layer by layer, at all times keeping the center of the stack slightly higher than the edges. The straws that are discharged against the screen will lie with some of the ends thereof projecting through the screen and as the stack is built up in this manner the straws at the bottom of the central portion of the stack will settle materially more than the straws adjacent to the screen, for the reason that the straws that project through the screen will prevent settling, and hence when the stack is completed and the top rounded off the center of the stack will be packed or settled more tightly than the outer edges. Then the operator removes the screen, and when this is done the ends of the straw at the edges of the stack will be relieved of the support of the screen and will settle in such manner that the outer ends of the outer straws of the stack will all incline downwardly and away from the stack to shed rain.

Having thus described our invention, what we claim, and desire to secure by Letters Patent of the United States therefor, is

1. The method of stacking straw which consists in first erecting a screen-barrier around the place upon which the stack is to be formed with the upper end portion of the barrier inclined toward the center of the place upon which the stack is to be formed, then depositing a quantity of straw within the barrier spaced apart from the barrier and finally discharging a blast of air ladened with straw downwardly and toward the barrier, said barrier retaining the straw and permitting the air to pass through and laying the straws adjacent to the barrier with their outer ends lower than their inner'ends.

2. The method of stacking straw which consists in first erecting a screen-barrier then depositing a quantity of straw spaced apart from the barrier, then discharging a blast of air ladened with straw downwardly and to- IIO ward the barrier and then directing the airblast ladened with straw to different parts of the stack being formed to cause the straw to lie upon the stack with the outer ends of the straws lower than their inner ends.

3. The method of stacking straw which consists in first erecting a screen barrier around the place upon which the stack is to be erected, said barrier having its upper portion inclined inwardly toward the center of the place upon which the stack is to be formed, then discharging a blast of air ladened with straw into the barrier in a direction tending to lay the straws within the barrier with their outer ends slightly lower than their inner ends, then directing the air-blast and straw to different parts of the stack to build up the stack with a greater quantity of straw upon its center than upon its edges.

4. The method of stacking straw which consists in discharging a blast of air ladened with straw in a nearly horizontal direction against a screen-barrier which will permit parts of the straw to project through it and then removing the screen-barrier to permit the outer ends of the straws adjacent to the barrier to settle.

5. The method of stacking straw which consists in first erecting a screen-barrier with its upper end inclined inwardly, then discharging a blast of air ladened with straw against the barrier in a direction to lay the outer ends of the straws in a plane slightly lower than the inner ends and discharging the straw against the barrier in a manner to project portions of the straw through the barrier, and then removing the barrier, to form a stack with inclined sides and to permit the outer ends of the straws that were adjacent to the barrier to settle more than the inner ends, and to incline the straws on the exterior of the stack downwardly and outwardly for the purpose of shedding rain.

6. The method of stacking straw which consists in first erecting a screen-barrier and then discharging a blast of air ladened with straw toward the barrier, said barrier tending to retain the straw and permit the air to pass through it.

7. The method of stacking straw, which consists in first erecting a barrier, then dischargmg a blast of air ladened with straw toward the barrier, said barrier retammg the straw and permitting the blast of air to pass through and then removing the barrier.

8. The method of stacking straw which consists in first erecting a barrier, then arranging a chute adjacent to the barrier, then forcing a blast of air ladened with straw through the chute toward the barrier, said barrier retaining the straw and permitting the blast of air to pass through it and finally removing the barrier.
