STRAW-STACKER.

SPECIFICATION forming part of Letters Patent No. 299,933, dated June 3, 1884.

Application filed November :'20, 1F83. (No model.)

Reference is to be had to the accompanyingv drawings, forming part of this specification, in which the same let-ters of reference indicate the same or corresponding parts in all the figures.

Figure l is a side elevation of our improved straw-stacker with some of the parts in section. Fig. 2 is a transverse section onthe line x2 .r2 of Fig. l. Fig. 3 is a longitudinal sectional elevation, and Fig. 4 is a plan View with same parts broken out. Fig. 5 is a transverse section of the turn-table on line z z of Fig. 4:, looking toward the left; and Fig. 6 represents the connection between the lower end of the long carrier and the turn-table.

We arrange an extension-frame, c, back of the separator b of the thrashiiig-machine by suitably connecting said frame with the axle c of the thrashingmachine truck and suspending it from the sills d of the same with yoke-bolts e, or other approved means, and on the rear portion of this frame we arrange a turn-table, f, on a circular supporting-bed, g, permanently attached to the frame a, the turn-table being tted with a guard-rim, h, projecting downward from, its periphery below the face of the bed to guide it around the bed and keep the turntable in its position thereon. The turntablef also has an annular rabbet, i, in the inner periphery, in which rabbet the guard-rollersj, iitted on brackets k, attached to the cross-beam. Z bear, to further assist in keeping the turn-table in its position. The turn-table f has a toothed rim, m, a tached to guard-rim h., and extending about half the circumference of the turn-table, and a wormwheel, n, on the shaft o gears with 5o this toothed rim for turning the turntable forward and backward suitably for swinging the straw-carrier p as required for delivering the straw on the stack. The shaft o has a bearing at one end in the sliding box q, with which a shifting-lever, s, is connected suitably for :disconnecting the worm from the turn-table when it may be desired to have the straw-carrier p stand and discharge in one position. The shaft o is geared by a wheel, t, with a worm, a, on a short shaft, o, which has a bevelwheel, w, which gears with the driving-shaft as by the bevel-wheels y or z, according as the clutch a' is shifted to connect them for turning the carrier p to the right or left.

For automatically shifting the clutch a' to enable the carrier to be reversed satisfactori ly, we have a clutclrshifting lever, b', carrying a heavy weight, c', at its upper end, and arsuitable proximity to the turn-table, to be shifted by the arms d', attached to it, said arms raising the lever from the inclined position to which it falls past the vertical position, so that said lever falls the other side and reverses the clutch, and said lever b being arranged in a to acquire momentum by its fall after passing when the lever is arrested at the ends f' of the slotted fulcrum, which will positively shift the clutch. y

The driving-shaft x is to be turned by a belt from any suitable driver working on the pulley g.

The straw is to be discharged out of the rear end of the separator b of the thrashing-machine and over the turn-table, on the top of which we have arranged a short endless carrier, h', over a table, i', and under the sidesj' of a low hopper, said carrier working on the rollers k' and Z', which are mounted in the ends of the supportingbars fm', respectively. The roller Z', at the upper end of the carrier h', has a sprocket-wheel, a', by which it is driven to work the carrier with a chain-belt from the sprocket-wheel o' on a shaft, p', that is mounted in suitable bearings on the top of the turntable f, and extending across the top of the same, and gearing with the large bevel-driver q' on a vertical shaft, s', arranged in the axis ranged to extend upward from the clutch in slotted fulcruin-plate, e', along which it swings the vertical line,.to cause a thrust on the clutch I ool `mounted in opposite bearings, p2, thereon,

whereby the shaft partakes ot' the circular turning` movements of theY table, and its p inion q2 travels around on the bevel drive-wheel q on the vertical drive-shaft sf, when the table is adjusted around. The construction of parts for supporting the turn-table and oper- I ating the carrier 7i and elevator simpliiies the structure, and is an advantage over those stackers in which the turn-table rotates on a central vertical pivot-pin, as in such structures two separate counter-shafts are essential on the stationary bed-frame of the turn-table.

The side bars m' of the supporting-frame of the carrier 7L are pivoted at t to standards w', suitably mounted on the turn-tablef, and near the upper ends said side bars have legs x, resting on the top ofthe turn-table, so that said carrier 7L and its supporting-frame may be turned up and supported against the end of the separators for being transported.

The carrier 71, discharges the straw from its upper end upon the long endless carrier p, by which the straw is to be elevated to the stack. rlhis carrier runs on the rollers y', attached to the shaft z', which has its bearings on the top of the turn-tablef, and is provided with the sprocket-wheel a, to be turned by the same driving-chain that turns the roller Z of the carrier h.

The side bars b2v of the frame of the carrier p have slotted plates ci, that hook onto the shaft c, for supporting the lower end of said carrier-frame on said shaft, and the said shaft has similar slotted bearing-supports d2 on the top ofthe turn-table, into which the shaft may be readily placed when the carrier p is to be set up for use, and from which the shaft may be readily removed with the carrier around it when the machine is to be packed in the condition for being transported. The drivingchain will then be detached from the wheel a2.

The frame of the carrier p has joints at e2 to enable it to be folded up, and said frame has a wire or rope suspending-yoke, f2, by which it is hooked tothe rope g2 of a derrick, h2, pivoted at i2 on the top of the separator-frame and. supported by the guy jz. The derrickrope g2 winds around the shaft 7s? of a windlass employed to raise and lower the carrier, and having a ratchet, Z, and pawl m2 for holding it in position.

By providing a shiftable clutch, a, in connection with reversing-wheels on the drivingshaft x, and devices for automatically adjusting the clutch to reverse the motion' of the turn-table, the elevator and intermediate-carrier are moved back and forth in a horizontal circular plane, and therefore the straw is continuously and uniformly delivered around on all parts of the straw-stack, which is very desirable in this class of machines.

As the shaft ois adjustable at one end by suitable means, such as the sliding box q and pivoted lever s, it will be obvious that the worm or gear a on the shaft can be moved into or out of engagement with the toothed rim of the turn-table,whereby, if the said worm or gear be adjusted by its carrying-shaft o out of engagement with the turn-table, the latter, together with the intermediate carrier and elevator, can stand in a stationary posit-ion or be freely and rapidly adjusted around in a horizontal plane to any desired position. If the shiftable clutch a be adjusted to such position between the reversing-wheels y/ and z as not to engage the clutch on either wheel, and the shifting-lever b be brought to a perpendicular position and held in that position by suitable means-such as acatch or stop-1t will be obvious that both reversing-wheels stand loose on the driving-shaft x, and therefore the shaft o will not be revolved. Vhen the parts are in this position and the worm or gear a is engaged with the toothed rim m, the turn-table will be locked in a stationary position, together with the elevator. where small straw-stacks are to be made, and it is not necessary for the elevator to move back and forth in a horizont-al plane to uniformly distribute the straw. The elevator can also be quickly adjusted around and locked in any required position by moving the sha-ft 0 to disengage the worm or gear a from the toothed rim m, and then properly adjusting the turn-table, after which the worm or gear is again engaged with the toothed rim to lock the turn-table.

The novel mechanism provided by us places the structure under control of the attendant, renders it convenient to manipulate, and so adapts the machine that the straw can be deposited in any one place orinacircular range, while the automatic circular sweep of the elevator can be changed to a longer or shorter arc by properly iixing the clutch shifting arms d d farther apart or closer together on the turn-table, or into sockets o2 thereon provided.

Ve do not broadly claim the combination, with a thrashing-machine, of a pivoted laterally-swinging straw-elevator and a pivoted conveyer intermediate of the machine and swinging elevator to follow the lateral swing of the elevator and transfer the straw thereto; but
