MARTIN IIEINEKE, OF SPRINGFIELD ILLINOIS.

STRAW-STACKER.

SPECIFICATION forming part of Letters Patent No. 618,092, dated January 24, 1899. Applicatiofifiled October 12, 1898. Serial No.693.303. (No model.)

To all whom it may concern.-

Be it known that I, MARTIN HEINEKE, of Springfield, in the county of Sangamon and State of Illinois, have invented certain new and useful Improvements in Straw-Stackers, of which the following is a specification.

This invention is designed to provide a raddle or drag stacker that may be built onto a thresher.

It relates to various features in the construction of the stacker.

It is exemplified in the structure hereinafter described, and it is defined in the appended claims.

In the drawings forming part of this specification, Figure 1 is a side elevation of my improved stacker, illustrating the means employed to raise and lower the discharge end of the stacker while stacking and to fold the swinging section back onto the thresher preparatory to going on the road. Fig. 2 is a vertical section lengthwise of the stacker, illustrating the straw-carrying machanism. Fig. 8 is a detail of the means employed to make the stacker-floor continuous while the stacker is in use, while permitting one section to be folded back onto the other section. Fig. 4: is a plan of the principal part of the stacker. Fig. 5 is a detail of the swinging flap that forms a part of the stacker-floor. Fig. 6 is a detail in perspective of means used to transmit motion from the main raddle-belt to a secondary underdraft drag that coacts with the raddle to give the straw a preliminary lift, while compressing it in a manner to make its subsequent conveyance more easy and certain.

The stacker-frame is composed of two sections 4. and 5, one of which is mounted on a turn-table under the delivery end of the thresher and held at its upper end against vertical swing while the other is pivoted to swing vertically on and over the upper end of the horizontally-swinging section. The vertically-swinging section has arms, as 5, 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 traverses the horizontally-moving section. The shaft 8 has a crankhandle 10,by which it is turned, and the handle is preferably geared to the shaft, so as to increase the leverage of will be between the pivot and the drums.

This permits the discharge end of the vertically-swinging section to be raised and lowered to deliver the straw at different heights, and it also enables the section 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 sufiicient 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 Fig. 1 one of the operative positions of the vertically-swinging section is shownin 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 apart 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 35 of the horizontally-swinging section, concentrio with the pivot of the vertically-swinging section, and place the floor of the verticallyswinging 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 verticallyswinging section I place a swinging flap 36.

The flap has pivot-pins 36 on its ends in 7 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 fiap 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 pivotpins 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-fin Fig. 3. As the vertically swinging section is swung over onto the deck of the thresher the nose of the flap encounters the floor of the horizontallyswinging 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. 3. 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, 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 straw-diverter 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 cross-bar 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 belts to run around pulleys. The raddle runs around pulleys 13 on the drive-shaft 12, crosses the hopper portion of the stacker at a slight up ward incline, and runs under side pulleys 15 and upward above floor 35 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, passes over pulleys 19 near the pivot of the sections, and

I 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.

To aid in starting the straw up the somewhat steep incline of the horizontally-swinging section and to compress it, so that it will carry easier and without scattering, I place an under-draft drag above the 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 idler-pulleys 15 in a manner shown in detail in Fig. 6. The pulleys 15 have short shafts journaled in the side walls of the stacker. Pulleys 32 are fixed onto the protruding ends of the short shafts, and belts 3& connect pulleys 32 with pulleys 33 on the ends of shaft 23 of pulleys 24.

The idlers 15 are driven forward by the backward motion of the raddle-belts, and the direction of motion thus attained is just what is needed to give the under run of the drag the required backward motion. 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 be guided in the direction the arm points when the upper section is approximately Vertical; but it is not essential that the drum act as the guide.

What I claim is 1. In a stacker, the combination of a lower section swingable horizontally, an upper section pivoted on the lower section to swing vertically upward and downward to distribute the straw and backward to fold into portable position, an extension of the upper section beyond the pivot thereof and a line connected with the extension and extended around a line-guide located approximately on a right line drawn through the pivot and through the connection of the line with the extension when the vertically-swinging section is in a vertical position, substantially asset forth.

In a stacker, the combination of a lower section swingable horizontally,- an upper section pivoted on the lower section to swing vertically upward and downward to distribute the straw and backward to fold into portable position,- an arm on the upper section extended beyond the pivot thereof, a line connected with the arm, and a winding-drum for the line pulling in the direction the arm points whenthe vertically swinging section is approximately vertical, substantially as set forth.

3. In a stacker, the combination of a hori-' zontally-swingable section held against verti cal swing and having a straw-receiving hop= per in its lower end, a vertically-swingable section pivoted to the upper end of the lower section, means for swinging the upper section on its pivot, and araddle running through the sections and across the hopper, substantially as set forth.
