T0 all whom it may concern,.-

Be it known that we, EDWARD HUBER and JACOB W'. MILLER, citizens of the United States, residing at Marion, in the county of Marion and State of Ohio, have invented certain new and usefulImprovements in Swinging Straw-Stackers, of which the following is a specification, reference being had therein to the accompanying drawings.

The invention has reference generally to apparatus for stacking straw. More particularly, however, it relates to the novel construction of the mechanism employed4 for automatically swinging from side to side the stacker proper, whereby an even distribution of the straw is obtained.

In building straw-stackers heretofore it has been the custom to arrange a turn-table upon a wheeled frame of any desired construction or upon the rear of the thresher-frame and to mount upon said turn-table the stacker, employing such means for actuating the turntable as would cause the stacker to automatically move' from side to side a limited distance. This general construction we have embodied in the invention hereinafter described; but the particular construction and combination of parts which make up the stacker is 'a departure from the present state of the art. This is especially true with respect to the shifting mechanism; and our invention consists inthe novel construction of the actuating mechanism for the turn-table, which will be more fully hereinafter described and shown in the drawings, in which- Figure 1 is a side elevation of our improved stacker. Fig. 2 is a rear elevation thereof. illustrating the driving and shifting mechanism. Fig. 3 is a plan view, partially broken away, further illustrating the shifting devices. Fig. 4 is a detached view of the bevelgears in section; and Fig. 5 is a section onl line Fig. 4, looking in the direction of the arrows, illustrating the arrangement of the clutch mechanism.l

The invention will be shown anddescribed as used in connection with the type of strawdischarging apparatus known as pneumatic straw-stackers. We do not limit ourselves to this type, however, as it is obvious that any discharging apparatus may be mounted upon the turn-table, which is actuated by the mechanism hereinafter described.

- The reference-letter A represents any suitable supporting-frame upon which the stacker and its parts are adapted to rest, and B a delivery-pipe secured within said frame, adapted to communicate with the thresher proper. A turn-table D of any desired construction is mounted upon the framework and has bearings upon the same,`so as to admit of rotation, said turn-table being providedwith a plurality of gear-teeth upon its periphery and held in its proper position upon the framesupport by means of the retaining-plates E.

4These plates are securely bolted tol the supporting-frame and carry at their ends proj ections a, which extend over a portion of the circular iiangehon the interior of the turn-table. Rigidly attached to the table by means of braces F andG is the stacker proper, I-I, one end of which communicates with the delivery-pipe B.

The actuating mechanism for the turn-table is of the following construction: A drivingshaft I is mounted in suitable bearings I, secured to the frame-support, and carries at one end and iixedly secured thereto a drivingpulley J.' Upon its free end the shaft is adapted to carry two bevel-gears K and L, loosely'sleeved thereon, and between said gear-wheels a double clutch M, rigidly attached thereto. Upon a shaft N, journaled in bearings in the frame A and at right angles to the driving-shaft I, is a bevel-gear O,

adapted to mesh with the gears K and L. On

the free end of the shaft Nisarranged a wormgear I), adapted to mesh with the gear-wheel Q, having bearingsl in the main frame andl having rigidly attached upon the same a gearpinion R. Mounted upon the framein a manner similar to the gear Q is aNgear-wheel S, which meshes with the gear-pinion R and has iiXedly secured upon the same a gear-pinion T, the latter pinion being adapted to mesh with the gear-teeth upon the periphery of the turn-table. The driving-shaft I, beingloosely j ournaled in the bearin gs or boxes l,is capable of a limited lateral movement derivedfrom the shifting device hereinafter described, which permits the clutch M to engage alternately with the gears K and L.

IOO

The clutch consists of an apertured block adapted to be sleeved upon the shaft and provided with a wedge-shaped lug CZ, said lug being adapted to receive a set-screw or bolt e, which rigidly secures the clutch to the shaft. Upon the bevel-gears K and L, as plainly shown in Fig. 5, are arranged blocks f, eX- tending a slight vdistance above the faces of the gear-wheels, which form a bearing against which the lug CZ of the clutch proper abuts when the shaft is shifted through the gearwheels. These blocks f are shown in section in Fig. et.

are of the following construction:

A shifter U is mounted in the projecting arms of one of the retaining-plates E, located upon the supporting-frame at a point above the driving-shaft I. The arms of the plate form a bearing for the shifter, upon which the the latter is enabled to be moved in the are of a circle. The shifter consists of a curved metallic bar g, provided with extensions projecting from either side of the center, the inward projection having a horizontal slot h and the outwardly-projecting portion carrying an upright lug t', the lug being arranged in the path of pinsj and j', which are inserted in apertures ,j2 in the rim of the turn-table. Secured to the frame A beneath the shifter is a downwardly-extending supporting-bar 7a. At the lower end of this bar and pivotally attached thereto is a shifting lever Z, which lever projects upwardly, the free end of which is adapted to extend through the slot 71, in the shifter, as plainly shown in Figs. 2 and 3. Adj ustably secured to the driving-shaft I are the collars m and a, and interposed between the collars is a shifting block 0. The block is adapted to slide upon the shaft and is provided with an apertured lug p, through which aperture a pin q on the shifting leverrextends. The shifting lever Z is pivoted to a spring-lever r by means of the link s, the latterlever being pivoted in turn to the frame A at t. w is a bracket apertured at the center, through which aperture a headed rod t is adapted to pass, one end of which rod is attached to the free end of the spring-lever r. Between the bracket and the headed end of the rod is interposed a spiral spring m.

The parts having thus been described and shown, their operation is as follows: Motion e beingcommunicated to the drive-pulley J, the

It will be seen by this construction that our clutch is exceedingly simple and is further movement of the table the pin will carry the shifter along until the shifting lever Z comes in contact with the same. The lever will then be driven to one side, carrying with it the shifting block o. This movement of the shifting lever causes the spring-lever r, through the link connection, to rise, thereby compressing the spring The stops or collars m and a are arranged at `such distances from each other that the lever-arm will pass the center in either direction at the time the shifting block strikesl the same. Upon further movement-of the table the shifting block will be forced against the stop a until the clutch M is withdrawn from its engagement with the bevel-gear K. At this moment the shifting lever being but slightly over the center the spring will cause the lever fr to throw the clutch immediately into engagement with the bevel-gear L, thereby reversingthe movement of the table. The collars 'm anda, bcing adjustably secured to the `driving-shaft, can be set at any desired distance from each other, so that the proper throw will be obtained for the shifting arm.

Having thus described our invention, what we claim, and desire to secure by Letters Patl. In a straw-stacker, the combination with a main supporting-frame and a turn-table mounted thereon, of a driving-shaft, a double clutch secured thereon, a plurality of gearwheels loosely sleeved on said shaft, a gear connection between the gear-wheels and the turn table, and actuating mechanism for shifting the shaft through said gear-wheels, whereby said double clutch engages with a different gear and whereby the direction of rotation of said turn-table is reversed.

2. In a straw-stacker, the combination with the main supporting-frame and a turn-table mounted thereon, of a driving-shaft, adouble clutch fiXedly secured thereto, a plurality of gear-wheels loosely sleeved onsaid shaft, said gear-wheels being arranged upon opposite sides of the clutch, and a gear connection between the gear-wheels and the turn-table, and
