CONVEYER ATTACHMENT FOR THRASHlNG-MACHINESf SPECIFICATION forming part of Letters Patent N 0. 434,338, dated August 12,1890. Application filed January 19, 1888. Renewed March 11, 1889. Serial No. 302,939. (No model.)

To all whom it may concern.-

Be it known that 1, CHARLES J. HARTLEY, of the city of Decatur, county of Macon, and State of Illinois, have invented certain new and useful Improvementsin Attachments for Thrashing-Machines, of which the following is a specification.

It is the object of my invention to provide a thrashing-machine with elevating and conveying mechanism that may be compactly disposed in a manner to preserve equilibrium when the machine is on the road, and that will enable the grain to be discharged in various directions.

In the drawings accompanying and forma part of this specification, Figure 1 is a side view of the elevator and an end view of the conveyer, showing both in working condition. Fig. 2 is a diminished side view of the elevator and conveyer, the actuating mechanism shown in Fig. 1 being omitted. Fig 3 is a side view of the elevator in position for transportation, its operative position being shown by dotted lines. Figs. 4, 5, 9, 10, 11, 12, and 13 represent details of construction to be hereinafter specified. Fig. 6 shows the hopper of the conveyer with the casing broken to expose the interior thereof. Fig. 7 is a transverse vertical section of the hopper. Fig. 8 is a plan of the conveyerand the mechanism most nearly related thereto.

The elevator 1 has buckets, of the customary or any suitable construction, and also has spout 2. Conveyer 7 has hopper 6. Horizontal bar 8 connects with the conveyer under the center of the hopper and extends obliquely across the top of the thrasher to a pivotal connection near the center thereof. Concentrio with the pivot of bar Sis arc-formed bearing 9, clearly shown in Fig. 8. Bracket 95 is pivotally connected with shaft 26, as shown in Fig. 8, and bar 8 is firmly secured to the bracket. The bar 32 is also connected with the bracket, and it is slotted vertically at its outer end. A bolt with a clamp-jaw 33 and a nut with an adj Listing-handle 34 provide means for securing the conveyer to bar 32. (See Fig. 12, where the bar is shown in said stud and over the conjoining lower end of rod 12 is sleeve 14. (See Fig. 5,where the sleeve is represented in section.) Frame 15 embraces the elevator and is provided with upper bearings for shaft 17 and lower bearings for the trunnions of frame 21. Shaft 4 in frame 21 carries bevel pinion 75 and sprocket-wheel 30. Shaft 19 carries bevelpinion 20 and sprocket-wheel 29. Shaft 3 carries bevel-pinion 27 and sprocket-

wheels

28 and 74. (See Fig. 9, where the frame with its mechanism is illustrated in detail.) Tubular shaft 26 traverses the top of the thrashingmachine and is adapted to receive at either end an end of shaft 3. Bearings 31 hold shaft 26 and are themselves held by diverging braces 22 23, suitably secured to the sides of the machine.

In hopper G is cone 36, mounted on tubular shaft 45. On the shaft under the cone is sprocket-wheel 38. The chain 39 on wheel 38 has vertical scrapers 40. Plate 41 under the conveyer furnishes an extended bearing for shaft 45. Plate 43, having stepped surfaces, as shown in Fig. 7, is secured to plate 41 by bolts 44-, and band 42 is held in the intervening space in a manner permitting free rotation. Slotted lugs 51 extend from opposite sides of band 42 and register with lugs on frame 25. Bolt 48 extends through frame and provides a journal for sprocket-wheel 47, which is provided with an upwardly-projecting rim 46, that forms a square socket that receives the square block 85 on the lower end of shaft 45. The shaft is closed at its lower end, has lateral openings, as shown, and is provided with removable plug 37 in its upper end.

The elevator is sustained by shaft 17, which is adjustably secured to shaft 26 by clips 35. (See Fig. 13, where the shafts are shown in section and a clip in side elevation.)

The conveyer has longitudinal partition 56, and the hopper has partial covering 55. (See Fig. 8.) Vhile the device is in operation the outer end of the conveyer is sustained from the upper end of the elevator through pivoted arm 54, rod 53, and bail 52, and the frame 25 is held in connection with band 42 by bolts 50, which have oblong heads. hen it is desired to arrange the parts preparatory to going on the road, the conveyer is swung into the position shown in solid lines in Fig. 8, the rod is detached from the bail, and the conveyer is clamped to bar 32. Bolts 50 are turned to pass through their slots, the sleeve 14 is raised clear of the junction of the stud with the rod, and the rod is disconnected from the stud and lowered until the bolts are clear of the band. The conveyer is then swung to the position shown by broken lines in Fig. 8, the rod 12 is reconnected with the stud, the clips 35 are loosened, and the elevator is swung to the position shown by solid lines in Fig. 3. It only remains to secure the elevator and the conveyer in their new positions, which maybe done in any desirable manner, and the machine is in complete equipoise and ready for the road. In effecting this adjustment there has been no disarrangement of drivechains, and consequently there will be no necessity for rearrangement when the machine is again put in operation.

The shaft 19 is the center from which all motion is distributed. The chain 72 (shown in Fig. 1) connects wheel 28 (see Fig. 11) with a wheel of the thrashing-machine. The direction of the rotation of wheel 28 is immaterial, as if in one direction connection may be made from wheel 74 with a drive-wheel on one side of the elevator, and if in the contrary direction connection may be made from the reversely-rotating wheel 29 with a drive-wheel on the opposite side of the elevator, the chain 73 acting as the power-transmitter in :either case. The rotation of wheel 30, through which the conveyer-chain is driven, maybe reversed to suit circumstances by placing pinion in mesh with the upper surfaces of pinions 20 and 27, instead of with the lower surfaces, as shown in Fig. 9. This indifference to the direction of the rotation of the main shaft enables connection to be made with the most accessible shaft of the thrasher.

When the conveyer is in operation it may be turned in any direction.

The partial covering of the hopper obviates the necessity of carrying any considerable quantity of grain around the sprocket-wheel, and the cone acts as an agitator of the grain and a protector of the sprocket-wheel.

The shaft 45 is to be oiled internally through the opening, usually closed by removable plug 37.

The device as a whole is well adapted to be used with an automatic scale and register, which may be easily secured to the spout of the elevator. I

I claim as new and desire to secure by Letters Patent- 1.
