To all whom it may concern:

Be it known that I, MARTIN Hnnrnxn, a

citizen of the United States, residing at Springfield, in the county of Sangamon and State of Illinois, have invented certain new and useful Improvements in St-raw-Stackers, "of which the following is a specification.

V Inthe development of the art of stacking E ing. and similar machines, many varieties of ,fltackers have been produced. It is desirable that the delivery ends of such stackers of the mechanical-carrier ty tain as close an approximation as possible to a perpendicular line, in order that the delivery of the material to the stack shall be kept as close to the middle thereof, at all points, as the stack grows in height, as is possible. Stackers which are pivoted at or near the material receiving point, so that the outer or straw delivering ends in being raised and lowered swing on such pivots, cause such delivery ends to depart rapidly from a perpendicular line, and thus occasion 15 considerable manual labor in the building of a properly shaped stack. A leading ob'ect of my invention 1s to. .produce a sta er in which the pivotal ,32,, points shall be so disposed as that the outer J 30,91- straw delivering end shall die art but moderately from a er endicu ar line dropped from said end w en the stacker ,is in its. aver e position. pm ;-;A further 0 ject of said invention is tov T5 provide in such a stacker a continuous ra or carrier running throughthe sevm1 sections from the receiving point to the I delivery point, thus avoiding the mechanical l 1* complexity incident to theuse of several in- Wfl defiendent raddles or carrier belts,

further object is to provide in such a I stacker, and in combination with such a carrier as stated, a second outer carrier f I, in the upwardly-extending carrierand 006 ating with the first-named e or carrier-belt to compact the straw after itis received by the stacker and,

it up to the outer pivoted .andmems for driying the same. I firther feature consists in making the m continuous without interfering the foldingover of the pivoted outmrdlycxtending carrier-section.

vention, as well as a detailed description 56 of the structures and mechanisms by which the various objects are attained, will appear hei'pirfiafter.

e erring to the accompan in drawin which are made a part hereoff an d on whi cl i similar reference characters indicate similar parts, Figure 1 is a side elevation of one variety of straw stacker embodying my invention, as the same appears when attached to or mounted upon the rear end of a threshing machine or'separator; Fig. 2 a central vertical sectional view lengthwise of the stacker illustrating the straw-carrying mechanism; Fig. 3 a top or plan view of the principal part of the stacker; Fig. 4 a detail sectional view illustrating the means em-- ployed to make the stacker floor continuous during the time the stacker is in use, while permitting one sect-ion to be folded back onto the other section; Fig. 5 a detail plan view of the swinging flap forming part of said means; and Fig. 6 a detail in perspective of means employed to transmit motion from y the main raddle-belt to the second cooperating carrier of the lower carrier section.

The stacker-frame is composed of two sections 4 and 5, one of which in the arrangement shown is mounted upon a turn-table under the delivery end of the thresher and held at its upper end against vertical swing, 85 while the other is pivoted to swing verticall on and over the upper end of the 11011- zontally-swinging section. The verticallyswinging sectlon has arms, as 51, extending beyond the pivot 6, on which it swings, and lines 7 extend from the arms downward to drums 9 on a shaft 8, which is mounted in bearings carried by the horizontally-moving section. The shaft 8 has a crank-handle 10, by which it is turned, and the handle is preferably geared to the shaft, so as to increase the leverage of the handle, and a detent should be provided in the customary V manner to hold the shaft against back mot-ion. The arms 51 are so extended with relation to the dpivot of the vertically-swinging section an the location of the drums 9 that when the vertically-swinging section is upright, or approximately so, the connections of the lines with the arms will be between the pivot and the drums. This ermits the discharge end of the vertica lya, objects and features of said inswinging section to be raised and lowered to deliver the straw at difi'erent heights, and it also enables the sect-ion to be swung over onto the deck of the thresher. To effect the result last named, the drums are turned in a direction to raise the vertically-swinging section, and when it is nearly vertical its motion is accelerated until suflicient momentum is developed to carry it over the pivot. It is then permitted to descend to the deck of the thresher, controlled in its descent by the crank, the drums, and the lines, and when it is desired to put it into use again the operation of raising and lowering is reversed. In this case the drum is placed at the proper position to swing the upper section of the stacker past a vertical line rising from its pivot; but it is obvious that if a pulley were placed where the drum is the drum might be located at almost any point on the lower section or elsewhere. It is essential that the line he guided in the direction the arm points when the upper section is ap roximately vertical; but it is not essential that the drum act as the guide.

In Fig. 1 one of the operative positions of the vertically-swinging section is shown in solid lines, the vertical position is shown in dotted lines, and the position on the deck of the thresher is shown in broken lines.

The form of the raddle preferably employed in the stacker necessitates the use of a floor in each of the sections, and it is a part of my invention to make the floors. continuous without interfering with extreme backward swing of the vertically swinging section. To accomplish this result, I provide a circular bearing 17 at the upper end of the floor 55 of the horizontally-swinging section, concentric with the pivot of the vertically-swinging section, and place the floor of the vertically swinging section tangential to the circular bearing, but out of contact therewith. In the narrow space between the circular bearing-surface and the floor of the vertically-swinging section I place a swinging flap 36. The flap has pivot-pins 46 on its ends in line with one of its edges, and such pins are pivoted adjacent to the end of the floor of the vertically-swinging section in such manner that the swinging edge of the flap extends nearly to the circular bearing and completes the continuity of the floor. The swinging edge of the flap points normally toward the center of the circle of the bearing-surface, or approximately so, and it is'narrow enough to swing past such surface when occasion demands. On the outer end of one of the pivot-pins of the flap is fixed an arm 37, which is held against a stop 39 by a spring 38, as shown in Fig. 1, and under these conditions the flap maintains the relative position shown in Fig. 2 and in solid lines in Fig. 4. As the vertically-swinging section is swung over onto the deck of the thresher passes the adjacent edge of the flap encounters the floor of the horizontally-swinging section, which is also tangential to the circular bearing-surface, and swings backward against the stress of'spring 38 to the position shown in broken lines in Fig. 4. In swinging the vertically-swinging section back to an operative position the flap is carried back to its normal space-bridging position by spring 38, and the stop 39 prevents motion to a farther extent.

The carrier portion of the horizontallyswinging section extends obliquely upward, to a point above the deck of the thresher, so that the long pivoted carrier-section can freely fold over into its position of rest, and its lower end diverges horizontally. A hopper 11 is formed in the upper surface of the horizontal extension to receive straw from the thresher. A material guide or de- Hector 2 is built onto the discharge end of the thresher 1, and the stacker is supported on a turn-table carried by extensions 3 of the sills of the thresher. A cross-bar 30 is pivoted at 31 to the upper surface of the thresher in a line coincident with the axis of the turn-table, and rods 29 extend from the crossbar to a bar 28 in the upper end of section 4 and hold such section against vertical swing, while permitting free horizontal motion.

The raddle or drag is composed of belts, as 21, having cross-slats, as 22, the ends of which are thinned at their connections with the belt to enable both surfaces of the belt to run around pulleys. A preferred form is shown in detail in my Patent No. 661,607. The raddle runs around pulleys 13 on the drive-shaft 12, crosses the hopper portion.

of the stacker and runs under guide pulleys 15 and upward above floor 55 to the circular bearing 17. From there it runs over flap 36 and floor 35, turns around pulleys on shaft 18 at the end of the vertically-swinging section, runs backward under floor 35, over pulleys 19 near the pivot of the sections, and runs downward and under pulleys 20 to the drive-shaft. The raddle is driven from-the thresher by any of the well-known gearings that permit horizontal swing, and the pulleys 15 inside the hopper have housings 16 to protect them from the straw. v

To aid in starting the straw up the somewhat steep incline of the horizontallyswinging section and to compress it, so that it will carry easier and without scattering, I place a secondary raddle or underdraft drag above the main raddle, as shown in Fig. 2. This drag is preferably composed of belts 26 and cross-slats 27. It runs around rollers 24 and 25, and it is driven in this instance from the guide-pulleys 15 in a manner shown in detail in Fig. 6. The pulleys 15 have short shafts 6O journaled 82 are fixed onto the 82 with pulleys 33 on in the side walls of the stacker. short shafts, and belts Pulle s rotruding ends of t e 34 connect. ulleys the ends of s aft 23 a discharge guide for the threshed straw, of a stacker com swingable frame pivotally connected with the thresher by widely pivots having an unobstructed space berising a horizontally separated vertical of alloys 24.
