STRAW-STA CKER.

SPECIFICATION forming part of Letters Patent No. 484,427, dated October 18, 1892.

Application filed October 8, 1891;

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 relates to mechanism for giving the carrier-frame horizontal oscillation and depositing the straw in an arc of a circle.

It consists in the details of construction and combinations of parts hereinafter set forth and claimed.

In the drawings accompanying and forming a part of this specification, Figure 1 is a side elevation of a stacker embodying my invenplan of certain details of the oscillating mech- I anism.

Frame 1 is mounted on Wheels for convenient transportation, and is provided with circular track or Way 3. Frame 2 is mounted on track 3 and has the partly-toothed wheel 4, concentric with such track. A standard 5 is supported from each rear corner of frame 2 and is provided each with a pulley 6 at its upper end. Ways 7 are secured to the front edges of the standards, and blocks 8, carrying rollers 9, are adapted to move vertically on the ways. Cables 10 connect with the blocks, run over pulleys 6, and are secured to shaft 11. A worm-wheel 12 is fixed on an end of the shaft. A worm 13 meshes with the wormwheel, and crank 14 provides means for rotating the worm and so raising or lowering the blocks 8. Frame 15 is connected pivotally with the front end of frame 2 and with the front or lower end of the straw-carrier frame 16. The carrier-frame is trussed from below by means of bars 16 and 16, together with king post or brace 16 and the bars, in addition to strengthening the frame, are of utility in the operation of raising and lowering the same. A pair of draw-bars 17 are placed on opposite sides of the carrier-frame $erial No, 408,090. (No model.)

and are connected pivotally with such frame and with frame 2. The connection with frame 2 is at the base of standards 5, and the connection with the carrier-frame is somewhat to the rear of the pivotal conjunction of the carrier-frame with'frame 15. As a result of this arrangement the carrier-frame cannot swing upward with frame 15 for a pivot without raising the swinging ends of the drawbars and so compelling the forward end of the carrier to move rearwardly over the center of the supporting-platform and compensate for the change of weight on the rear end, which is caused by raising the carrier. In other words, the carrier as a whole is balanced with reasonable accuracy on the turn-table; but when the rear end of the carrier-frame is raised it of course swings toward the turn-table and disturbs the eqnipoise. This disturbance is compensated for or neutralized by the .action of the draw-bars, which force the forward end of the carrier rearwardly as the rear end is raised. So, also, when the carrier-frame is lowered, as seen in Fig. 1, as soon as the descent of the rear end of the carrier is arrested the forward end is held against further descent by the draw-bars acting in conjunction with the relatively-oblique frame 15. In operating this part of the device the crank 14: is turned, thus elevating the blocks 8. The rollers 9 bear against bars 16 and force the rear end of the carrier upward, with the result as to self-adjusting equipoise heretofore explained.

Referring to the oscillating mechanism, 18 is the main shaft, and 19 a drive-pulley therefor.

20 is a double or two-end clutch splined on the main shaft.

21 and 22 are pinions mounted loosely on the shaft on opposite sides of the clutch and having each a clutch member opposed to and adapted to mesh with the clutch aforesaid.

23 is a gear-wheel meshing with both pin- 1ons.

24: is a worm on the same shaft as the gearwheel.

25 is a Worm-wheel driven by the Worm.

27 is the shaft of the worm-wheel, and 26 is a pinion on such shaft, meshing with wheel 4 of frame 2.

The mechanism just specified enables the motion of the main" shaft to be applied to the wheel of the oscillating frame',,-the direction of the motion depending on which pinion 21 or 22the clutch engages. This is determined by mechanism automatically operated, which will now be explained and which comprises this feature ofmy inventioni Toothed wheel 28 is provided with a tripfinger 29, which extends inwardly beyond theperiphery of wheel 4. A spring 36 tends to hold the finger in the position shown in Fig. 3, while permitting it to-move in either direction. Pins 31 and 32 on wheel 28 are adapted to be alternately acted on by the finger, thus imparting the motion of the finger to the WheeL- Pins, as 39; ex-t'end through lugs suitabl y placed on wheel 4 and atpropee inter valstrip the fihger'29L Wheel 34 is fixed on shaft: 38' and provided witlil te'eth which mesh Witli tlie" teeth on wheel 28!
