ARTHUR, J. HARTLEY, OF DECATUR, ILLINOIS, ASSIGNOR TO C. J. HARTLEY 00., OF DECATUR, ILLINOIS.

SUPPORTING AND DRIVING DEVICE FOR CONVEYERS AND THE LIKE.

T0 alt whom it may concern:

Be it known that I, ARTHUR J. HARTLEY, a citizen of the United States, residing at Decatur, in the county of Macon and State of Illinois, have invented certain new and useful Improvements in Supporting and Driving Devices for Conveyers and the Like, of which the following is a specifica tion.

This invention relates to certain improve ments in supporting and driving devices for conveyers and the like; and the objects and nature of the invention will be readily understood by those skilled in the art in the light of the following explanation of the accompanying drawings illustrating what I now consider to be the preferred embodiment of my invention.

An object of the invention is to provide a mounting and drive for lateral swingable conveyers to permit vertical as well as lateral swing of the conveyer without throwing the gearing or driving mechanism out of gear or operative relation.

The invention consists in certain novel features of construction and in combinations and arrangements as more fully and pan ticularly set forth hereinafter.

Referring to the accompanying drawings:Figure 1, is a side elevation of the mounting and drive showing the receiving end of a coneveyer carried thereby. Fig. 2, is a rear or end elevation. Fig. 3, is a top plan view with the conveyer removed. Fig. 4:, is a vertical section in the plane of the line ltr, Fig. 3. Fig. 5, is a detail vertical sectional view, on an enlarged scale, taken in the same plane as Fig. 4:, and showing the positions of the parts when the free end of the conveyer is elevated from normal horizontal position, dotted lines indicating the transverse axis on which the conveyer swings.

In the drawings 1, are supporting bars fixed to and projecting from an elevator or other element not shown in the drawings.

2, is a yoke-like supporting bracket having horizontal side sockets receiving the supports 1, said supports being suitably bolted or otherwise fixed to the bracket. This bracket is provided with horizontal separated alined journal boxes 20, receiving the horizontal shaft 3. At one end this shaft Specification of Letters Patent.

is provided with driving gear 30, to which the power is applied for actuating the conveyer hereinafter described. At its intermediate portion between the boxes 20, the main shaft 8, is provided with a bevel gear 31.

The supporting bracket 2, is formed with a central vertical hollow hub or bearing box 21, in which is rotatably mounted a turn table 4, having a hollow upper end or head 40, above the box21, and resting and turnable thereon.

5, is a vertical shaft passing concentrically through and rotatable in the turntable and at its lower end having bevel gear 50, meshing wit-h and driven by bevel gear 31, and at its upper end provided with a bevel gear 51, arranged in the hollow upper end or head 40 of the turn table. The turn table is rotatable about a vertical axis coincident with the axis of rotation of the shaft 5.

The head or hollow upper end 40, of the turn table is provided with a pair of alined opposite horizontal trunnions 41, arranged in a vertical plane to one side of the vertical plane including the axis about which the turn table is rotatable.

6, is a vertically swingable frame, yoke or bracket having a pair of depending ends extending down at the opposite sides of the turn table head and formed withbearings 60, receiving and rotatable on the trunnions 41, which form the axis on which the frame 6, is vertically swingable. This frame 6, is formed with a central transverse horizontal journal box 61, in which the horizontal shaft 7, is rotatable. At its inner end the shaft 7, is provided with a bevel gear 70, located over and in mesh with and driven by the bevel gear 51. At its outer end the shaft 7, is provided with a sprocket or other power transmitting gear 71.

A horizontally disposed conveyer is fixed to the swingable bracket 6. I show the hopper or receiving end of the trough or casing of a conveyer containing a rotary conveyer screw or the like, not shown, and having a conveyer shaft 80, provided with driving sprocket 81, or other suitable gear arranged in operative relation with respect to the sprocket 71, and driven thereby through the medium of a sprocket chain 82, indicated by dotted lines. I show the receiving end of the conveyer 8 having a bracket or base 83, fixed. thereto and depending therefrom and bolted or otherwise fixed to the swing able bracket 6, and arranged thereon so that the bracket 6, and the conveyer 8, can swing vertically and horizontally together or as one member.

The trunnions a1, forming the axial line on which the frame 6, and conveyer are swingable vertically are so arranged with respect to the gears 51 and as to permit vertical swing of the conveyor without throwing said gears out of mesh, that is, out of operative power transmitting relation. The horizontal alined trunnions 4:1, are spaced a distance apart so that the engaging teeth of the gears 51,'70, are arranged between the two trunnions, and the axial line of the trunnions is tangentially arranged with respect to the circular paths of movement of said gears and intersects approximately the outer end portions of the engaging teeth of said gears.

By the arrangement of elements described, the conveyer 8 can swing horizontally on the vertical axis of the turntable as a center without disturbing the operative power transmitting relation of the various gears described. When thus swinging horizontally the parts turn on the box 21, of the main supporting bracket 2.

In swinging the conveyer horizontally about the vertical axis of the turn table, particularly when the conveyor is swung over the deck of a thrashing machine, obstructions are often encountered rendering it necessary to raise the out board or free end of the conveyor in order to clear the obstruction. By the arrangement of elements described this vertical movement is permitted without throwing the gearing from operative relation inasmuch as the gears 51., 70, intermesh loosely and the common longitudinal axis of the trunnions 41 (the axis on which the conveyer is swingable vertically) transversely intersects approximately the outer end portions of the engaging teeth of the gears 51, 70. These gears so loosely intermesh that when the delivery end of the spout or conveyor is lifted over an obstruction gears 51, 70, will be separated to the extent that they will. intermesh only at the lower (outer) portions of their teeth. As these gears intermesh loosely and are held in the just mentioned abnormal relation only while the conveyer is being lifted over the obstruction, the wear on the gears due to such abnormal relations is of no consequence. The normal running or operating position of said gears vis illustrated by Fig. 1.

It is evident that various changes and modifications might be resorted to in the forms, constructions and arrangements of the parts described without departing from the spirit and scope of my invention, and hence I do not wish to limit myself to the exact disclosure hereof.

A conveyer supporting and driving mechanism comprising a main supporting bracket, a horizontal drive shaft mounted therein, a turn table mounted therein to rotate on a vertical axis, a vertical shaft mounted in the turn table to rotate on an axis concentric with the axis of rotation of the turn table, bevel gears operatively con necting the horizontal and vertical shafts, a vertically swingable bracket mounted on the turn table and provided with a horizontal shaft rotatable therein, bevel gears operatively connecting said last mentioned shaft and the upper end of the vertical shaft, a conveyor fixed on said swingable bracket and adapted to be operatively connected with and driven by said last mentioned horizontal shaft, said vertically swingable bracket swinging on a horizontal axis approximately intersecting the engaging teeth of the bevel gears between the vertical shaft and the horizontal shaft carried by said swingable frame.
