STRAW-STACKER.

SPECIFIGATION forming part of Letters Patent No. 676,481, dated J' une 18, 1901. Application filed July 3, 1899. Serial No. 722,705. (No model.)

To @ZZ whom t may concern,.- I Be it known that I, EDGAR A. WRIGHT, a citizen of the United States, residing at Oanton, in the county of Stark and State of Ohio, have invented certain new and useful Improvements in Straw-Smokers, of which the following is a specification, reference being had therein to the accompanying drawings.

Figure l is a side elevation of part of a thresher and separator mechanism and of a straw-stacker embodying my improvement. Fig. 2 is a plan View of the frame and mechanism by which the stacker is supported and rotated horizontally and showing a part of the main stacker-carrier. Fig. 3 is a side elevation of the stacker-frame and mechanisms, showing the two carrier-sections in the positions occupied when at work.. Fig. 4E is a central vertical longitudinal section. Fig. 5 is a central Vertical transverse section. Fig. 6 is an elevation from the inner or frontend. Fig. 7 is a vertical transverse section of the clutch forfreeingor disconnectingthestackerframes from the rotating mechanism. Fig. S is a bottom plan View of the parts in Fig. 7. Fig. 9 is a side elevation of the same. Fig. l0 shows detached some of the details in Figs. 7 to 9. Fig. 1l shows the spring device for throwing the clutch.

In the drawings I have shown a portion of a threshing and separating mechanism to which those devices are adapted to .be connected which particularly` embody the present invention; but. it will be understood that s'o far as the thresher and separator are concerned they can be of any preferred sort;

The main frame, which supports the stacking mechanism, is rigidly secured to and extends backward from the rear end and the lower part of the frame of the thresher. This stacker-frame is shown as having the longitudinal sills l l, extending backward from the bottom sills of the thresher. These longitudinal sills are connected by cross-grts 2 2 and 3 3, the latter being preferably metallic bars extending from one sill l to the other and secured to the under side thereof. The cross-girts 2 2 may be lighter and made of wood and have their upper surfaces in higher planes, being preferably about level with the tops of the sills l. At the center, transversely of this main bottom frame and at a point suitably near the' rear end thereof, there is placed a strong bracket 3l, which is bolted to two of the cross-girts 2. Preferably it is a strong casting and is formedwith an upwardly-extending tubular bearing or post 31a. Around it turn the movable parts of the stacking mechanisms and their frame, which are constructed and arranged as follows:

33 indicates a ring concentric with the axis `of the aforesaid bearing at 31f. It has a horizontal base-plate part 33a and a vertical flange 33h.

` 33c indicates clips or retainingvears bolted to the girts 2 2 of the frame and engaging with the horizontal part 33a.

34 34 are cross-bars rigidly secured to the" ring 33 and extending transversely of the main bottom frame.

35 35 are bars fastened to those aforesaid at 34 and to the ring 33 and extending longitudinally. At their rear or outer ends they are secured to a cross-bar 36, and from the outer end of the latter there extend forward and inward inclined braces 37 37',v which are also irmly fastened to the ring or adjacent framework. These bars 37 are at their rear ends extended beyond the cross-bar 3G and are shaped to have or are connected to bearings, as at 37a, for the supporting of the longer rear part of the stacker-conveyer. The longitudinal bars 35 are preferably made of angle-irons; but to increase the strength of such material I generally supplement them with reinforcing-bars, as shown at 4:9.

At 32 there is a bracket rigidly secured to the upper frame, being preferably fastened to the aforesaid bars 34. It is placed so as to coincide withthe bearing-bracket 3l on the lower stationary frame, it having a pivotal connection with the latter, preferably by means of the tubular extension 31a.

From what has been above described it will be seen that the 'upper frame is rotatable upon the lower stationary one, the centering thereof being eifected by the bracket-castings 3l 32, and it is around their vertical axis that the rotation occurs.

Upon the top rotary frame are mounted the two parts of the carrier and elevator. The

IOO

first of these is indicated as a whole by A and the second by B. The part A is composed of side boards 45 and the inner end board 50 and suitable cross-framing pieces. In this frame and casing is mounted the endless straw-carrier 51, its belts or chains passingover the rollers 41 41a. Power is transmitted to the inner or rear roller by means of/ ward from and are secured to the inner part 4 'of the rotary frame. The outer or rear end of the carrier-frame is supported by the legs 42, which extend downward a suitable dis-l tance and can rest upon the cross-bar 36.

The othervlonger rear inclined part B of the i straw-carrier is at its inner end hinged to the outer end of the rotary frame, there being laterally-projecting hinge arms or bars 52 at the axis of its lower roller. the straw-carrier may be of any of the usual constructions as concerns its framing and its carrier-belt. The carrier is driven from the inner roller,and the latter receives power from the chain 47, which engages with the sprocketwheel 3S and is driven by the sprocketwheel 53. The two aforesaid sprocket- wheels 53 and 46 are secured to a transverse shaft 28, mounted in the upper revolving frame. This shaft is driven by bevel-gearing, comprising the wheels 54 at the inner end of the shaft 23, the horizontal bevel-gear 55 on the vertical shaft 56, mounted at the axis of the mechanism in the said brackets 31 and 32, a second horizontal bevel-wheel 57 at the lower end of the shaft 56, and the bevel-wheel 5S. The bevel-wheel 5S is secured to the shaft 27, which is mounted in the lower stationary frame. It extends to the side of said frame and has a sprocket-wheel 2G, which is driven by the chain 25, engaging with a sprocket 24 on the prime power-shaft 59, the latter receiving motion through a belt from the thresher engaging with its belt-wheel G0.

From the train of devices above described the motions are transmitted to the carriersections in the two parts A and B simultaneously. At the same time the upper rotary frame, together with the carrier-sections, is oscillated horizontally as follows: 9 indicates achain which extends more or less around the ring 33, it engaging with a vertical iiange 33b thereof. lts ends may be fastened to the ring at suitablepoi-nts, or the ring can be provided with teeth to engage an endless chain. The central part of this chain engages with a sprocket-wheel 6 on the vertical shaft 6, this shaft extending upward from the bracketplate 61, fastened to the cross-bars 3 The sprocket-wheel 6 is secured to the shaft and can be engaged with any suitable rotary driving device. As shown, the driving de- This part B of.v

on the shaft 63.

vice consists of the worm -wheel 5, loosely mounted on the shaft 61 and adapted to be engaged with the sprocket-wheel 6 by movable clutch-pins 7. These pins can be slid into and out from the apertures 62 in the sprocket-wheel, they sliding through corresponding apertures in the worm-wheel. 3 is a clutch-lever by which the pins can be thrown into or out of engagement with the sprocketwheel. This can be accomplished in any suitable way. As shown, it is effected as follows: The pins 7 are secured rigidly to a plate 75. The lever 8 is formed in two separable halves 76 76, each half at its inner end carrying a half-ring 77. On the inner side of the ring halves there are grooves 78, which coincide and provide a seat for the edge of the plate 75. 0n the outer face of the ring there are spiral or cam-like ribs 79, which are fitted in ways at SO in the lugs S1, that extend upward from the frame-plate 61. When these several parts are properly assembled, it will be seen that the plate 75 and the pins 7 can be raised or lowered by merely moving the lever 8 to the right or to the left, this causing the ring part to be elevated or lowered by reason of the action of the spirals or cams 79 in their guideways. By these devices the wheels 5 and 6 can be quickly disconnectedor connected, as desired.

The worm-wheel 5 is driven by the worm 4 This shaft can be driven in either direction, it having two wheels 19 and 2O secured to it at a suitable distance apart.

64 is a shaft for driving the wheels 19 and 20, it receiving power from the aforesaid shaft 59 through the pinion 23 and the wheel 22. This shaft 64 has two loose piuions 13 and 21, respectively meshing with the aforesaid wheels 19 and 20. Between these loose wheels is the sliding clutch 15, splined to the shaft 64 and adapted to engage with said wheels 1S and 21 alternately. The clutch is moved by the lever 14, pivoted at 65 to a suitable frame-bar 13, this lever being cona nected to the clutch by shipping pins or jaws of any preferred sort. When the clutch en-A gages with the wheel21, the worm-shaft 63 is driven directly by the wheels 2O and 21 in one direction, and when the clutch engages with the pinion 18 the worm-shaft 63 is driven in the opposite direction, there being an idlerwheel 17 interposed between the wheels 18 and 19 for reversing the motion.

When the shaft 63 is rotating in one direction, the ring 33 and the top rotary frame are, together with the stacker-sections, moved to the right. Vhen the clutch is reversed and the shaft 63 is driven in the opposite direction, the aforsesaid parts are moved to the left.

The clutch is provided with partsby which it can be reversed by hand and others by which it can be reversed automatically. To move it automatically, the following devices are used: 29 is a trip-rod whose operative part is concentric with the axis of rotation IOO IIO

of the stacker, the ends of the rod being fastened to the rotary frame. It is provided at suitable intervals with adjustable collars 66, held by set-screws 30, and which can be placed as desired. The aforesaid lever 14 has an arm 67 lying in the path of the trip-collars, and the latter alternately strike it and operate the reverse lever and clutch. The other arm of the lever 14 is pivoted to the sliding rod 68, which has the handle 69, whereby the operator can throw the clutch whenever he desires.

To insure that the clutch shall promptly and quickly travel to the end of its path and engage with the wheel 18 or 21, toward which it has been started by the above devices, I combine with the lever 14 a spring S6, which is compressed while the lever is swinging to its central position and then expands and acts to carry the lever to the end of its path after crossing the center line. Such a spring can be arranged in any of several ways, as shown it being arranged to bear against a lug at 87, which guides the spring-sustaining rod 86, the latter being pivoted at S8 to a suitable support secured to the frame.

The entire train of devices for oscillating the stacker can be thrown out of action or into action by means of the clutch 89 on the main driving shaft 59, this clutch being splined to the shaft and the pinion 23. being loose thereon. The clutch can be moved in any suitable way, as by a lever 90 and ahandrod 91.

Vhen devices similar to those above described a-re employed, it will be seen that I can accomplish several important ends. It is very desirable on many occasions to temporarily disengage the stacker from the mechanism which operates it and leave it free to vibrate, although disconnected from the I power-driven parts, (which latter can continue in their normal movement,) so that the operative who may be on the stack can easily by hand move the elevator around the axis at 3l 32 from point to point or even hold it stationary at any point for a time, as he may deem fit, in order to shape the stack properly. To attain this, it is only necessary to move the lever 8 in the proper direction to withdraw the pins 7 from the wheel 6, for after this is done, while the power parts continue in their normal movement, the stacker-frames are free to be turned by hand, as desired. Again, it is frequently necessary to stop the stacker-frame at some point and hold it there a longer or shorter time; but the action of the wind-even a light wind-will prevent this if the stacker is free and disengaged in the manner last described, and therefore it becomes necessary at such times to have a lock. To thus permit the stacker to be stopped at any point, and at the same time to hold it there locked, it is only necessary to move the clutch S9 to its inactive position, for thereafter the entire train of oscillation-causing mechanism will be stopped, and the worm 4 and worm-wheel 5 act as a rigid lock to prevent the stacker-frames from turning, the pins 7 in such case being in their upper position and engaging with the wheel 6. With respect to the arrangement of these parts for causing the oscillation of the stacker-frames it Will be noticed that there is considerable difference when compared with the arrangementin other constructions. One of my purposes is to vertically shorten the mechanism or place conipactly the frames andthe horizontal carrier, and to accomplish this I have removed a great part of the gearing and shafting which has heretofore been placed at the principal center of vertical oscillation and have placed them at points remote from that center, and particularly have placed them where their weight can be more advantageously provided for. The arrangement which I have devised is of great importance in stackers whose baseframes are rigidly and permanently attached to the rear of the separator-casing. I bring the gearing and the heavy metallic parts forward and inward and place them where their weight is carried easily by the rear axle of the main machine and prevent them from exerting a powerful leverage behind said axle,and,again, by arranging them in this wayI am enabled to bring the topmost part ofthe stacker devices to a low horizontal plane and insure that not only shall all of the straw from the upper part of the separator be caught, but also that the section A shall be low enough to properly receive the cha and material that is thrown out by the winnower.

To prevent the straw from being carried laterally away from the lines of rthe stacker by the wind or otherwise, I employ a curtain or flexible chute 92, which is secured to the rear end of the separator and is of such shape and dimensions as to allow the straw to freely descend and at the same time furnish at the sides guards against their being deflected. The curtain is indicated by 92, and with it is combined a supporting rod or hoop 93, which when the curtain is'down lies in about the central horizontal-plane of the separator and holds the curtain in proper position,but which can be turned upon its pivot-axis at 94 when the parts of the machine are to be folded, the positions occupied when folded being illustrated in Fig. 1. This ligure shows that the several parts which I have above described can be arranged compactly when out of use. The outer roller of the section A when the machine is at work is in or close to the vertical planes of the roller of the outer section, so that the straw can be delivered immediately from the section A to the section B; but the overhanging part of the inner section does not interfere with the throwing back of the outer section close to the separator when the parts are to be packed.
