SEEQIFECATION forming part of -Letters. Patent No. 676,482, dated J une 18, 1901.

Application filed July 3, 1899. Serial No. 722,736. [No modeh) T0 @ZZ whom, it may concern:

Be it known that I, EDGAR A. vWRIGHT', a citizen of the United States, residing at Canton,in the county of Stark and State of Ohio, have invented certain new and useful Improvements in Straw-Stackers, of which the following is a specification, reference being had therein to the accompanying drawings.

Figure 1 is a side elevation of a portion of a grain threshing and separating mechanism and of a straw-stacker embodying my improvements. Fig. 2 is a side elevation of the same, showing the parts folded up for storage or transportation. Fig. 3 is a side View of the lower parts of the stacker on a larger scale. Fig. ft is a plan view of the gearing and clutch at the center of the rotary frame. Fig. 5 is a rear view of parts of the apron or carrier driving mechanism. Fig. 6 is a plan View showing the main frame and some of the movable parts above it. Figs. 7 to 1l show details. Fig. 12 is a front view of the ieXible curtains at the side of the horizontal carrier. Figs. 13 and 14 illustrate a modification in the supporting devices for the carrier.

In the drawings I have shown the rear part of a thresher and separator of one of the sorts adapted to have my improvements applied thereto.

From the bottom part of the main frame of the machine there extends backward a lower rigid frame formed of the sills 2 2, rigidly secured to the main frame, together with crossgirths of suitable number and material, as shown at 1S 18. Upon this main bottom frame are supported the movable frames and the operative parts.

31 indicates a bracket or frame casting secured to the main bottom frame at the place where the central parts of the horizontallymovable frames are to be put. It comprises vertical legs or plates, which are secu red to the bottom frame, an upward-rising tubular bearin g 31,and downward-extendin g bracketarms 31b for supporting some of the movable parts. Themainhorizontally-swingingframe is composed of the longitudinal bars 19, connected together by cross-bars 20 20, together' with bars 20h, which serve as inclined braces and also provide at their front ends bearings for the rear stacker elevator section. There is a ring or circular track 3 of relatively large radius secu red to the bottom stationary frame. Upon this track or ring rest supporting-roll- 'ers 26, which are mounted in suitable supports on the underside of the rotary frame 19 2O` At the center of the rotary `frame is the relatively large toothed ring or wheel/1, the boss or hub of which rests upon the aforesaid frame-bracket 31 on the stationary frame. It is rigidly secured to the bars 20, lying above it.

Upon the rotary frame are mounted the two sections A and B ot' the straw carrier and stacker. The inner section is normally horizontal when at work, it being formed with the sides 12 and the rear end Wall 12, within which is arranged the endless carrier 12b. The latter is supported upon and rotates With the rollers 13ai and 14C. The shaft or spindles of the roller 13a rest in bearings which are mounted upon the supporting-standards 25, which rise from the inner end of the rotary frame. At the front end the carrier A is supported by means of legs 2l, which rest upon the outermost cross-bar 2O of the rotary frame. The outer longer inclined carrier-section B may be made in the usual way, having the side bars suitably joined and with the rollers at the top and bottom and the endless carrier supported thereon. At its lower end it is supported on the rotary frame by bearingpieces at the axis of the lower roller resting in the supports provided by the aforesaid bars. The endless belts on the sections A and B of the stacker are driven by the chains 9 and 9, the chain 9 extending from the sprocket-wheel 13a on the hinge-axis of the carrier-section A down to the sprocket-wheel 7 on the shaft Sa, mounted transversely of the rotary frame, and the chain 9iL extending from the sprocket-wheel 7 on the last said shaft to the wheel 15 on the hinge-axis of the outer carrier-section. Power is transmitted to the said chains 9 and 9a as follows:

28 is the main drive-shaft, mounted so as to extend or lie transversely of the machine on the lower stationary frame. At its inner end near the vertical axis of rotation of the upper frame it carries a bevelwheel 30.

ICO

This engages with the bevel-wheel 30, the shaft of which passes upward through the hub or tubular bearing 3l on the stationary frame. At the other end ot' this shaft there is a sprocket-wheel 33, which is connected by the chain 16 with a sprocket-wheel 23 on shaft 23a. This shaft carries a bevelwheel 34, which engages with the wheel 35 on the ato resaid shaft 8a.

Through the train of devices just described power is transmitted from the belt-wheel l to the sprockets and chains which engage withand actuate the rollers of the stacker'- sections A and B. Provision is also made for oscillating the frame lf) and 2O simultaneously with the movements of the straw-carrying Vbelts as follows:

536 is a shaftmounted on the main stationary frame, it having two loose bevel-wheels 30 30C. main driving-bevel 30 and are continuously rotated thereby in opposite directions.

37 indicates a clutch adapted to engage with either of the wheels 301 or 30C. 0n the shaft 36 there is a worm 29, which meshes with the worm-wheel 6 on the vertical shaft Gf, that at its upper end carries a pinion 5, which engages with the above-described toothed ring i 4. When the clutch 37 is in engagement with i the wheel 30, the worm and worin-wheel will y turn the oscillating parts in one direction;-l but when it engages with the wheel 30" the frames will be turned in the opposite direc- The clutch is automatically moved from -one beveled wheel to the other as foly tion.

lows:

38 is the shipping-lever, engaging with the clutch. It is secured to a vertical shaft 39, which is mounted in a bearing 40, supported by the base-plate 4l. Atl the upper end the shaft 39 is secured to a crank 42, having a cross head or bar 43.

44 44 are dogs pivoted to the crank-arm or its cross-head, each ot' these being formed with a hook at 45, a cam-surface at 46, and an upward-extending lug 47. The dogs are arranged oppositely to each other. At 4S there are cam-lugs on the bracket-plate, having their surfaces 49 situated in the path of the cams. The hook parts of the dogs are normally held in their outmost positions by means of springs 50. To release the dogs from the locking-lugs 49, use is made of trippins 5l, inserted in the toothed ring or wheel 4. These trip-pins can engage directly with the dogs to release the clutch-lever 3S and with the crank-arm 42 to throwthe clutch; but I have provided a mechanism for attaining superior results in this connection, as follows:

52 indicates frames or bars lying in lhe'path of the trip pins 5l. Preferably they are formed integrally as the legs of a loop or stirrup, as shown, bent from elastic metal. They are confined in position by lugs 53 at the ends of the cross-bar 43 and are held by the pivot- Thesewheels both engage with the' g crease rod 54.` When one of the trip-pins 51 is moved toward its dog 44, it rst impinges upon one of these` elastic bars 52 and must bend it, and therebT store up force in the loop before it (the pin) reaches the dog 44, and it continues to press against the elastic bar until it has moved the lug 47 far enough to release the dog from the catch-lug 4S. The instant that the dog is released the force stored in the spring-bar exerts itself and the crank 42 and its attached parts, including the shipping-lever, are quickly and powerfully Vthrust into their opposite positions, bringing the clutch into engagement with the opposite bevel-wheel 30b or 30C, whereupon the rotary motion of the revolving frame is stopped and its motion in the opposite direction is commenced, causing the pin 51, just referred to, to reverse its direction. As the crank 42 and the cross-bar 43 move in the way last described under the pressure of the trip-pins and the expansion of lthe spring the cam-face 46 on the other dog impi-nges on the cam-face 49 of the other stop-lug 4S, and these move the hook end of the dog inward until it passes the point of the lug 48, and thereupon the spring 50 immediately throws the hook ot' the dog outward to engage with the lug and lock the crank andthe shippinglever from movement. This locked condition is maintained until the opposing trippin (which has now started in its movement toward the cl utch-th rowing devices) impinges upon the other elastic arm 52, after which a series of steps will occ-ur similar to those above described, resulting in the reversing again of the clutch.

To supplement the elastic action of the parts at 52, I prefer to place between their ends a coiledsprng 55, it being around the rod 54.

Devices of this character for throwing the clutch are positive and reliable, avoiding the uncertainty which has been incident to other mechanisms and insuring that the clutch shall be completely thrown the entire distance necessary to effect the reversing.

I am aware that 'in stackers with reversible driving mechanisms for the stacker-frame use has been made oi" a clutch, a clutchthrowing lever, and a spring adapted t-o exert draft or pressure upon the clutch-lever on both sides of the central position of the lever and that the spring has been so arranged that the stacker-frame would energize the spring as the central or half-way point was reached and that the increased energy would be exerted upon the lever after the central position was reached and throw the lever to the other end of its throw; but I believe myself to be the iirst to have provided a clutchthrowing mechanism for such machine in which use was made ot' a lever and spring, with suitable adjuncts, so related that the spring shall transmit to the lever all of the torce which throws it and yet be held by a IOO IIO

positively-actinglock which must be released before the spring can exert force. upon it. Such a mechanism enables me to secure the desired movements of the clutch very quickly and with great force and in such way as to guard against any accidental throwing of the lever at a wrong instant, as sometimes results from the slack in the gearing or the lost motion in the parts. The positive lock and the devices for releasing it are so placed and related to the others that the lever will not be thrown until the desired instant and when thrownwill move with the full force of the spring, both ends being under compression. With the carriers above described I combine a peculiarly-arranged curtain or flexible shield for preventing the wind from carrying the straw out of line as it descends from the straw-tables in the separator. This curtain or shield is indicated, as a whole, by 60. It is made in two parts Gl 6l, one at one side and the other at the other side of the machine. They are supported upon a rod or bar 62 by means of rings 63 or equivalent carriers. The rod or bar 62 has a curved part bent on a line substantially concentric with the axis of rotation of the stacker and having its legs adjustably secured to the separator-frame, as at 64. The Vcurtain-sections 61 6l are made quite full.7 Their upper vedges are free to move along the curved rod 62, except that the parts which are adjacent to the separator-frame are preferably fastened stationarily. The curtains at their outer edges are left separate somewhat, so as to permit the straw to be readily carried by the horizontal carrier and delivered to the vertical carrier. 65 is a cord or rope connected to the curtain-sections near their upper edges and also connected to the horizontallyswinging frame. l/Vhen the frame moves in one direction around its axis, the draft exerted by the cord G5 causes the curtain to slip around on the rod 62 in the direction of the motion of the frame, one curtain-section becoming relatively taut and the other relatively full. Then when the stacker-frames are reversed the cord exerts draft upon the curtains in the opposite direction and the rings and curtains slip around toward the otherside of the machine guided by the rod 62. If desired, two cords can be employed, one extending from the left-hand curtain-section toward the right-hand side of the frame below and the other extending from the righthand curtain to the left side of the frame.

Vhen the machine is to have its parts packed together or folded up for transportation, the curtains and curtain-rods can be detached or swung downward and inward, as shown in Fig. 2, as the supporting devices for the rod G-l may include a hinge, as indicated in the drawings; but in this respect there can be modification, for, as shown in Figs. 13 and la, the supporting and guiding rod for the curtains is permanently stationary, and in this case the dimensions of the carrierframe are such as to permit the folding of the parts without interference with or from the curtain-support.
