TURN-TABLE FOR AUTOMATIC STACKERS SPECIFICATION forming part of Letters Patent No. 617,286, dated January 3, 189 9..

Application filed August 15, 1898.

To all whom it may concern:

Be it known that I, JosEPH GALLAND, of Mansfield, in the county of Richland and State of Ohio, have invented a new and useful Improvement in Turn-Tables for Automatic Stackers, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming part of this specification, in which- Figure 1 is a top plan view of my improved turn-table applied to a separator-frame. Fig. 2 is a front elevation of the same. Fig. 3 is a transverse vertical section. Fig. 4 is a side elevation partly broken away, and Fig. 5 is a partial longitudinal section.

My invention relates to the turntables employed in connection with automatic swinging or oscillating stackers, and is designed to cheapen and simplify their construction, to

26 lessen their weight, and to largely do away with the several screw or worm gears heretofore employed in such devices and which rapidly wore away in service.

My invention is especially applicable to 2 5 stackers which are attached to the thresher, though it may be used upon separate stackers.

In the drawings, 2 2 represent the rearwardly projecting beam of the thresherframe, to which the main frame 3 of the turn- 0 table is secured. Upon this frame is centrally mounted the lower grooved circle-plate, or rim 4, within which are mounted a series of balls 5, which are held in suitable relation to each other by separating-blocks 6, prefer- 3 5 ably of wood. Upon the balls rests the upper circle-plate 7, having a suitable lower groove to receive the balls and an inner depending flange 8, which fits neatly within the lower circle-plate. The upper plate is provided o with a series of teeth 9, which are engaged by a screw or worm 10, mounted in bearings 11, this screw-gear giving the oscillatory motion to the turn-table.

Upon the upper circle or ring is mounted a frame 12, having a central bracket 18, the

hub 14 of which fits over an 'upwardly projecting sleeve upon a lower central bracket 15 upon the main frame, thus giving a central pivot-bearin g for the turntable. Through these hubs extends a short vertical shaft 16, having at each end bevel gear-wheels 17 and Serial No. 688,585. (No model.)

18, which intermesh, respectively, with bevel gear-wheels 19 and 20 upon the transverse shafts 21 and 22. The shaft 22 extends centrally within bearings in the main frame of the 5 5 turn-table and is driven by belt connections to a pulley 23 thereon. Splined upon this shaft 22 is a jaw-clutch 24, which engages a loose sleeve carrying a pinion 25, intermeshing with a toothed wheel 26, mounted in a bearing 27 upon an arm of the center bracket 15. Secured to or integral with the toothed wheel 26 is a pinion 28, intermeshing with a toothed wheel 29, carried upon a long sleeve 30, which is loose upon the shaft 22. At the end of the sleeve 30 is provided a bevel-pinion 31, intermeshing with a bevel gear-wheel 32', carried at the lower end of an inclined shaft mounted in bearings 33. The upper end of this shaft is provided with a bevel gearwheel 34, which intermeshes with a pair of bevel gearwheels 35, loosely mounted upon a transverse shaft 36. Between these bevel gear-wheels 35 is a clutch 37, arranged to alternately engage them and actuated by a lever 38, connected by a pivoted link 39 with an actuating-lever 40. The end of this lever 40 is arranged to be contacted with by pins 41, secured to a supplemental arc-shaped plate 41, and to lock or hold the lever and 8c clutch in either of their adjusted positions I provide a sliding spring-latch 42 upon the lever 40, having an arrow-head end 43 arranged to contact with a stationary pin 44. It is evident that when the lever 40 and clutch 37 are moved in either direction this springlatch will snap past the pins and hold them in their adjusted position. The shaft 36 is provided with a universal joint45, and the bearings 11 for the screw-gearmounted upon this shaft are carried upon the plate 46, which may be swung away from the upper ring, so as to disengage the worm from its teeth, the plate being secured in its adjusted positions by a bolt 47 passing through a slot therein. 5 When the screw-gear is thus disconnected, the turn-table may be oscillated by hand.

Shaft 21 is provided near one end with a sprocket-wheel 48, which is connected by a chain 49 to a similar sprocketwheel 50, which drives the endless belt or web 51, which forms the bottom of the hopper 52,

table may be stopped or started by a lever 59, secured to the clutch 24 and actuated by the sliding hand-rod 60, which is held in its adjusted position by a pin thereon, which projects downwardly into holes in the plate 61, a leaf-spring 62 being employed to hold the pin in any of these holes.

The operation of the device is apparent. The straw and chaff dropping into the hopper are fed by the endless web forming its bottom onto the carrier, which carries them up the stack. During this operation the turn-table oscillates back and forth with a slow movement by reason of the alternate connection of the clutch 37 with the bevelgears 35, the straw thus being delivered as desired. By adjusting the pins 41 in difierent parts of their supporting-plate the table may be turned at any desired angle to the thresher and still receive its automatic oscillatory motion.

The advantages of my invention result from the simplifying and lessening of weight consequent upon my improved construction; from the fact that only one screw-gear is employed, to which is imparted a slow motion, so that it will not wear out rapidly; from the use of the counter-shaft upon the upper frame of the table, which drives both the web of the hopper and the carrier, and generally from the improved system of actuating connections between the driving-shaft and the driven part, including the moving Webs and the oscillating mechanism.

Many changes maybe made in the form and arrangement of the parts without departing from my invention, since I claim 1. A stacker turn-table having a driven shaft extending beneath the same, a countershaft upon and turning with the table, actuating connections between these shafts, a shaft at one side of the table, and having a worm intermeshing with an arc-shaped rack upon the table,an inclined shaft having bevelgear connections with the driven shaft and the Worm-shaft, and means for alternately re versing the rotation of the worm-shaft; substantially as described.

2. A stacker turn-table having a driven shaft extending beneath the same, a countershaft mounted upon and turning with the table, a short vertical shaft at the axis of the table, and having bevel-gear connections with the counter-shaft and driven shaft, a Worm at one side of the table intermeshing with an arc-shaped rack upon the table, an inclined shaft having bevel-gear connections with the driven shaft and the worm-shaft, and mechanism actuated by the table for alternately reversing the rotation of the Worm-shaft substantially as described.

3. A stacker turn-table having a driven shaft extending beneath the same, a countershaft mounted upon and turning with the table, a short vertical shaft at the axis of the table, and having bevel-gear connections with the counter-shaft and driven shaft, a worm at one side of the table, intermeshing with an arc-shaped rack upon the table, the worm shaft having bevel gear-wheels loosely mounted thereon, with a clutch between them, a lever connected to the clutch and actuated in the opposite directions by projections upon the table, and an inclined shaft having bevelgear connections with the driven shaft, and having a bevel wheel arranged to engage either of the loose bevel-Wheels upon the worm-shaft; substantially as described.

4. A stacker turn-table having a worm-gear connection arranged to oscillate the same, an adjustable base upon which the worm is mounted, and a jointed connection for the worm-shaft, to allow its disengagement from the table actuatingteethg substantially as described.

5. A stacker turn-table having a toothed frame, a Worm engagin g the same, a universal joint in the Worm-shaft, means for alternately reversing the rotation of this shaft and an adjustable mounting for the worm to permit its disengagement from the teeth; substan tially as described.

6. A stacker turn-table, having gear connections arranged to rotate the same, a lever arranged to alternately reverse the rotation of the connections, pins or projections upon the table arranged to actuate the lever, and

a latch carried upon the lever and arranged to hold the same in its adjusted position; substantially as described.

7. A stacker turn-table, having a driven shaft, slow-motion gearing connecting the same to a bevel-gear shaft, a pair of bevelwheels upon a common shaft engaging the bevel-wheel upon the connection-shaft, a worm upon the shaft carrying the two bevelwheels, said Worm engaging an arc-shaped rack upon the table, a clutch arranged to connect either of the bevel-wheels with their shaft, a lever connected to the clutch, and projections upon the table arranged to contact with and actuate said levers; substantially as described.

8. In a stacker, a hopper having an endlesswelo bottom, a carrier having an endless apron to which the Web leads, and a shaft having thereon sprocket-wheels one connected to and actuating each of the endless aprons or webs; substantially as described.

9. A stacker turn-table, having an upper oscillatory frame, a hopper thereon with an frame havin g at its front end a shaft provided with pulleys over which the carrier extends, a hopper upon the frame having an endless- Web bottom, and a counter-shaft upon the oscillatory frame having a sprocket-Wheel connected to and actuating the Web bottom, and another sprocket-wheel at its opposite end connected to and actuating the carrier; substantially as described.

In testimony whereof I have hereunto set my hand.

JOSEPH GALLAND.
