ISTRAW-STAQKER.

SPECIFICATION forming part of LettersPatent No. 601 ,66 '7, dated April 5, 1898.. Application filed September 2, 1897. Serial No. 650,365. (No model.)

To all whom it may concern: I

Be it known that I, ROBERT MOY, a citizen of the United States, residing at Modena, in the county of Bufialo and State of Wisconsin, have invented a new and useful Straw- Stacker, of which the following is a specification.

My invention relates to improvements in straw stackers of that class wherein the stacker may be swung automatically from side to side of the threshing-machine; and the primary object of the invention is to provide an improved stacker mechanism which is applied permanently to the threshing-machine to form an integral part of the same.

A further object'of the invention is to provide a novel supporting and actuating mech: anism for the swinging stacker in which the v parts are sustained in a peculiar manner to obviate the weight of the stacker mechanism binding or cramping the driving devices of,

the stacker.

A further object of the invention is to construct the swinging part of the stacker mechanism in a manner to enable the same to be 7 folded over and upon the threshing-machine without allowing any of the elements of the stacker mechanism to rest upon the ground.

With these ends in view and with such others as will appear from the annexed detailed description my invention consists in the novel combination of elements and in the construction and arrangement of parts, which will be hereinafter fully described and claimed.

To enable others to understand my inven tion, I have illustrated the preferred embodiQ ment thereof in the accompanying drawings, forming a part of this specification, and in which a Figure 1 is a plan view of my improved straw-stacker applied to a part of a threshing-' maehine,-a part only of the thresher being shown for the purpose of illustrating the ap- Fig. 2 is a vertical longitudinal sectional elevation on the plane indicated by the dotted 1ine2 2 of Fig. 1. Fig. 3 is a horizontal sectional view on'the plane indicated by the dotted line 3 3 of Fig. 2,-showing the driving and reversing gearing.

tional view on the plane indicated by the dotted line 4 4 of Fig.- 3 to show the mechanism Fig. 4 is a'vertical transverse sec-' for turning the swinging stacker-frame. Fig. 5 is a detail transverse sectional view to show the reversing mechanism for the stacker-adjusting shaft to impart the swinging motion to the swinging frame and the stacker carried thereby. Fig. 6 is a detail sectional view on the plane indicated by the dotted line 6 6 of Fig. 3.

Like numerals of reference denote corresponding and like parts in each of the severa figures of the drawings.

A part of the main frame or casing of an ordinary threshing-machine of any suitable or preferred construction is indicated by the numeral 1 in the drawings.

No novelty is claimed herein for the threshin g-machine, because myinvention is restricted to the stacker mechanism.

I contemplate the provision of a stacker which shall be applied permanently to a thresher-machine and form an integral part of the same,- and as a means for attaching the stacker to the threshing-machine I provide the main supporting-frame 2, which has its side sills 3 extended into the machine casing or frame '1 to be bolted or otherwise united solidly to the casing or frame 1. This supporting-frame extends rearwardl y beyond the main frame for a suitable distance, and the side sills of said frame 2 are braced by the transverse bars 4 and the diagonal bars 5, all of said parts being bolted solidly t0- gether. Above this main supporting-frame 2 is arranged the swinging stacker-carrying frame 6, which occupies a parallel relation to the main supporting-frame 2. This swinging frame 6 and the supporting-frame, 2 are coupled or united together by a vertical kingbolt or arbor 7, which passes through the diagonal bars 6 of the swinging frame and the diagonal bars 5 of the main frame2. On the lower face or side of this swinging frame 6 is applied and bolted a circular metallic track 8, and on the upper side of the supportingframe 2 is secured the brackets 9 of a series of antifriction supporting-rollers 10, upon which ride the circular track 8 of the swinging stacker-frame 6, whereby the swinging frame is adapted to turn freely in a horizontal plane on the king-bolt or arbor and the supporting-rollers. ing frame and the stacker is borne practi- The weight of the swingcally by the antifriction-rollers on the main supporting-frame, and by this construction the weight of the stacker is prevented from binding or cramping the gearing of the driving mechanism, thereby permitting the driving mechanism to turn freely with minimum friction and wear on the parts. This swinging frame is provided on its upper side with the cross-rails 11, which are suitably bolted to the frame and are spaced apart a suitable distance from each other. These cross-rails carry the brackets 12, which are bolted to the ends of said rails, and in the brackets is j 0ur naled a shaft 13, which forms the pivot-shaft for the foldable stacker and as a drivingshaft for the endless conveyer-belt of said stacker. From the brackets 12 of the swinging frame extend the arms 14, and from the rear cross-rail 11 on said frame extends another pair of arms 15. These two pair of arms 14 15 sustain an inclined board 16, the transverse shaft 17, and the idler-rollers 18, and around this board the rollers 19 on the shaft 17 and the idler-rolls 18 passes a traveling auxiliary conveyer 20, which is arranged below an upper inclined conveyer 21, so as to catch any straw which may escape from the conveyer 21 and to serve as a means for depositing the escaping straw upon the stacker-conveyer. The shaft 18 of the auxiliary conveyer 20 is provided with a chainwheel 22, around which passes a sprocketchain 23, which also passes around a sprocketwheel 24 on one end of the shaft 13, thus gearing the shafts 13 18 together for driving the conveyer 20.

The conveyer 21 iscarried by a frame 25,

which is pivotally or loosely attached to a shaft 26, which is journaled in suitable bearings 27, attached to the threshing-machine adjacent to the sieves or riddles thereof. This shaft 26 is provided atits end with a driving Wheel or sprocket 28, and on the shaft is mounted the conveyer-pulleys 29, around which pass the conveyer-belt 21, the other part of the belt or apron 21 passing. around idler-rollers 29*, suitably j ournaled at the free end of theadjustable frame 25. This conveyer 21 and its adjustable frame are arranged to occupy an inclined position between the sieves or riddles of the threshing-machine and the stacker-conveyer, and the free rear end of said conveyer 21 is designed to overhang the stackenconveyer in order that the and the inclined conveyer-frame are arranged the suspending and adjusting ropes 32, each rope being attached to the conveyer-frame 25 and wound upon the shaft 31, whereby the bers into alinement with each other and to enable the outer member 33 to fold upward with relation to the lower member 32 in order that the outer member may fold over and upon the threshing-machine 1. The inner or lower member 32 of the stacker-frame is loosely or pivotally mounted on the shaft 13,

' and this pivotal connection of the lower member 32 of the'stacker-frame is effected, preferably, by providing the said member 32 with forked arms or plates 35, which are rigidly fastened to the member 32 and which loosely embrace the shaft 13. The sectional stackerframe thus has its lower member pivoted on the shaft 13, which is carried by the swinging frame 6, and the two members of the stacker-frame are also pivoted togetherto enable one member to be turned upward with relation to the other member. The stackerframe thus has its members mounted for adjustment in a vertical direction, as well as to fold upon the thresher, and at the same time the stacker-frame is mounted on the swinging frame 6 to swing therewith in a horizontal plane, thus giving to the stacker-frame the desired lateral motion with respect to the threshing-machine. This stacker-frame carries at its outer end the idler-rollers 36, and around the rollers 37 on the shaft 13 and the idler-rollers 36 passes the endless conveyer 38 of the stacker, which conveyer is thus carried by the stacker-frame in a position to receive from the conveyer 21 and to deliver the straw out over the free end of the inclined stacker. The stacker is sustained in its proper position by means of the cables 39, which are attached to the outer member 33 of the stackerframe, and these cables 39 are carried through an eye 40 on the guide-bail41,which is mounted pivotally upon the top of the threshingmachine, the ends of the cables being coiled or wrapped on an adjusting-shaft 42, which is journaled on the machine 1 and provided with a hand-crank 43 and with a pawl-andratchet locking device 44.

The guide-bail 41 is erected above the machine 1 to give clearance of the stacker-suspending cables, and the weight of the stacker and the strain of its suspending-cables tends guide-bail in its raised position, I provide the holding-cable 45, whichis fastened at one end to the guide-bail and which has its other end coiled on the shaft 46, suitably journaled on the top of the machine 1, and said shaft is provided with a hand-crank 47 and with a pawl-and-ratch'et locking device 48. The described construction of the cables and shafts provides for the proper raising or lowering of the sectional stacker to sustain the same in its operativeposition and to enable the same to be folded, and said devices alsohold the guide-bail in position and enable the same to the stacker-section 32 and provided with a suitable crank and a locking device.

On the vertical king-bolt or arbor is mounted a double master-gear '55, which is arranged between the main supporting-frame 2 and the swinging frame 6, and this master-gear is provided with teeth on both its upper and lower 7 7 0, respectively, on an intermediate shaft 71,

surfaces,

In the main supporting-frame 2 is journaled a driving-shaft 56, one end of which has a pulley or chain-wheel 57, around which passes a belt or sprocket-chain to drive the shaft 56, and the inner end of this shaft carries a bevel gear-pinion 58, which meshes with a series of bevel gear-teeth on the lower face of the master-gear 55 for the purpose of driving the latter. On the swinging frame 6 is journaled a counter-shaft 59, the inner end of which has a gear-pinion 60, that meshes with the gearteeth on the upper face of the master-gear 55, and the outer end of this counter-shaft 59 has a sprocket-wheel 61, around which passes a sprocket chain 62, that passes around a sprocket-wheel 63 on one end of the shaft 13, that drives the conveyer belt or apron of the stacker. The described construction and arrangement of shafting and gearing provide for the transmission of power from a suitable shaft to the stacker-conveyer without in any way interfering with the horizontal turning movement of the frame 6 to swing the stacker in laterally-inclined relation to either side of the main machine 1. The driving-shaft 56 also carries a double pulley 64 65, around which pass the straight and crossed belts or chains 67 68, and these straight and crossed chains pass around other sprocket-wheels 69 one sprocket-wheel and its chain serving to drive the intermediate shaft 71 in one direction,while the other sprocket-wheel and chain serve to drive the shaft 71 in the other direction. The sprocket-wheels 69 70 are mounted loosely on the shaft 71, and said wheels are designed to be made fast alternately therewith by a shiftable clutch 72, which is keyed and slidably mounted on the shaft 71 to rotate therewith and to play back and forth between the wheels 69 70. I

To the clutch 72 is connected a fork 73 on the shipper bar or rod 74, which is slidably confined in suitable keepers attached to the front cross-bar of the main supporting-frame 2, and a trip arm or lever 75 is slidabl-$ con nected to this shipper arm or lever. This trip-lever is fulcrumed on the main supporting-frame 2, and it is held normally in positi on by means of a spring 76. Thistrip-lever 75 lies in the path of the detents 77, which are attached to the front side of the swinging frame 6, near the ends thereof, and as the frame 6 swings back and forth to move the stacker-frame and its conveyer laterally these detents strike the trip-lever alternately to shift the clutch back and forth on the shaft 71 into engagement with the pulleys or sprocketwheels 69 7 0 alternately. The swinging frame is turned on the king-bolt or arbor to give the laterally-swinging motion to the stacker bymeans of the cable or cables 78 79, which are attached to the respective sides or ends of the swinging frame 6 and which are coiled in reverse directions on the actuating-shaft 80,,one cable beingarranged to wind on the shaft'SO as the other cable is unwound therefrom. This shaft 80 is journaled in the frame 2 at a suitable distance from the shaft 71, and the two shafts 71 80 are geared together through the short shaft 81, journaled in suitable bearings on the frame 2 and having bevel-gears which intermesh with similar bevel-gears on the shafts 71 80, as clearly shown by the drawin s.

its the shaft 80 is driven in one direction by one of the pulleys 69 or 70, the shaft 71, andrthe short shaft 81 it winds one cable thereon and slackens the other cable to swing I the frame 6 and the stacker in one direction; When the frame 6 has reached the limit of its movement in one direction, a detent strikes the trip-lever to shift the shipper-rod and move the clutch in engagement with the other pulley or wheel, thus driving the shaft 71 in the opposite direction, and this reverse motion of the shaft 71 is communicated through the short shaft 81 to the shaft 80, which is thus reversed to wind the other cable thereon to pull the frame 6 in the reverse direction and give an opposite motion to the stacker until the other detent on the frame 6 strikes the trip-lever, whereupon the motion of the frame 6 is again reversed. At the same time the master-gear transmits the motion from the shaft 59 to the shaft 13 and the latter drives the stacker-conveyer and theauxiliary conveyer 20.

a suitable belt or chain which passes around a pulley or spocket-wheel on the shaft 26.

It is thought that the operation of my in- The conveyer 21 is driven by vention will be readily understood from the foregoing description, taken in connection with the drawings. I
