Application filed November 5, 1909. Serial No. 528,421.

To all whom "it may concern:

Be it known that I, JOHN Mantis, a citi- Zen of the United States,residing at Danvers, in the county of McLean and State of Illinois, have invented certain new and useful Improvements in Driving Devices for Drags, &c., and do hereby declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same.

This invention has reference to a new and improved driving device, which is more especially applicable to drags employed in connection with corn-shellers and similar machines, and may be applied to different styles of conveyors used in connection with different types of dumping and elevating machinery.

One of the objects of the present invention is in the provision of an interchangeable driving device which is capable of having power applied thereto to drive from one side, or changing the power connections from the side to the front, so as to drive from the front. Such an application of power, has its particular advantage in connection with drags when used with cornshellers, because at times it is impracticable to drive from the side of the drag, and likewise, at times it is impracticable to drive from the front; but with an interchangeable drive, power may be applied in the most convenient manner.

For a further and full description of the invention herein and the merits thereof, and also to acquire a knowledge of the details of construction of the means of effecting the result, reference is had to the following description and drawings hereto attached.

lVhile the essential and characteristic features of the invention are susceptible of modification, still the preferred embodiment of the invention is illustrated in the accompanying drawings, in which':

Figure 1 is a side elevation of the head of a drag or conveyer, showing the manner in which it is supported on a. receiving hopper and also showing the drive capable of being driven from the side; Fig. 2 is a plan view of what is shown in Fig. 1 with the addition of a tumbling-rod connection with the drag or conveyer drive; Fig. 3 is a side elevation of the head end of a drag or conveyer body; showing the drive which is used when power is applied from the front. The view further illustrates how the drive is placed in position; Fig. t is a view similar to Fig. 3, with the exception that the drive is in proper working position and has attached thereto a tumbling-rod driving from the front; Fig. 5 is a view similar to Fig. 4, except that a shield that is used to cover the gearing of the drive is in working position; Fig. (3 is a cross section as the same would appear if taken on the line 6-6 of Fig. 5; Fig. 7 is a perspective view of the supporting bracket and gear which is employed, as shown in Figs. 3 to 6 both inclusive, when driving from the front; Fig. 8 is a perspective view of the shield used to cover the gears, as shown in Figs. 5 and 6; Fig. 9 is a rear view of a supporting plate attached to the sides of the head end of the drag or conveyer, with certain parts cooperating therewith, broken away, and Fig. 10 is a view of a modified form of the bracket shown in Figs. 3, 4 and 7.

Like numerals of reference indicate corresponding parts throughout the figures.

In the drawings, 1 denotes duplicate plates, which, when used on drags or elevating bodies, are arranged upon opposite sides of the head thereof, substantially as shown in Fig. 2. The plate 1 has a central hub portion 2 forming a bearing for a shaft 3, extending transversely through the body of the drag, and on said shaft is carried a sprocket wheel 4:, or several such sprocket wheels, if desired, for operating a conveying mechanism movable through said drag or conveyer body. The conveyer mechanism forming no part of this invention, has been omitted. The shaft 3 extends beyond the opposite sides of the drag, for a suitable distance and is squared as at 5 so as to provide for attachment thereto of a tumblingrod 6, see Fig. 2, designed to be driven from some suitable source of power, preferably a horse power, and the tumbling-rod includes a knuckle-joint 7, which may be of any well known or approved construction for adjusting the rod 6 to the power. Thus it will be seen, that with the application of power, such as I have described, to the shaft 3, said shaft may be driven from either side of the drag.

On the opposite ends of the shaft 3 are carried bevel gear wheels 8, and it is through these gears, in a manner which I shall now describe, that I am enabled to change from a side drive to a front drive.

The plate 1 is provided with an arcshaped slot 9, of suitable length and width and preferably arranged concentric to the axis of the shaft 3. This slot for a portion of its length is contracted, as at 10, through the provision of inwardly carried flanges 11 which are offset, as at 12, see Fig. 6, to form a groove 13, between the flanges and the side wall of the drag, for the insertion and travel of a locking plate, to be further described, for securing a bracket in adjustable positions on plate 1. One end of the slot 9 is left its full width, as at 14, for the insertion of the locking plate previously mentioned.

The bracket to which reference has just been made, is composed of the two parts 15 and 16, and is best seen in Figs. 6 and T. The part 15 has the bearing portion 17 and the transverse bearing portion 18, also the head 19 by means of which the part 15 may be bolted, by bolts 20, to a head 21 of the part 16. Said part 16 has a bearing portion 22 and a base-plate 23. hen the parts of the bracket are assembled, substantially as shown in Fig. 7, a short shaft 2 1 is journaled in the bearings 17 and 22 of the parts 15 and 16 respectively, and said shaft has the squared end 245, to provide for connecting thereto a tumbling-rod 6 similar to the rod 6. In fact, when not driving the shaft 3 by the rod 6, the rod 6 is connected in manner seen in Fig. i, to the short shaft 2 1. Said tumbling-rod 6 includes a knuckle-joint 7 to provide for adjusting the tumbling rod 6" to its power.

Before joining or attaching the parts 15 and 16 of the bracket, in manner described, the short shaft 24 is passed through the bearing 22; a bevel. gear wheel 25 similar to the wheels 8, is then placed on the shaft, when the bracket parts may be secured. Constructing the bracket in two parts simplifies the insertion of the gear wheel 25 and provides for constructing the bracket in a compact form. The bracket could be in one piece but it would be cumbersome and impracticable.

To the base-plate 23 of the part 16, of the bracket, is attached, in an adjustable manner, a locking plate 26, which is shaped to conform to the walls of the slot 9 of plate 1, into which it is intended to insert the same, and the said plate is attached to the'baseplate 23 by bolts 27.

Vhen it is desired to apply power to the drag or conveyor body from the front. the bearing 18 of the two part bracket, above described, is passed over one or the other of the ends of the shaft 3, with the base-plate 23 of the bracket and locking plate 26 disposed in the position shown in Fig. 3, in which position, the locking plate 26 may be inserted through the arc-shaped slot 9, at 141, and the operator swinging or moving the bracket downwardly, as shown in Fig. 1, causes the locking plate 26 to move down in the groove 13, between the flanges 11, and the side wall of the drag. lVhen the parts are in a desired position, the operator tightens the bolts 27, which will bring the plate 26 up against the flanges 11, from the rear, and force the base-plate against the flanges from the front, thereby locking the bracket in working position, being that position shown in'Fig. 1. The shaft 3 forms the pivot on which the bracket, through the bearing 18 may be oscillated. It will be observed that the bracket with the gear 25 has a considerable range of adjustment, whereby the shaft 24: may be brought into proper alinement with. its driving connection, the tumbling-rod 6 for imparting power to the gears 25 and 8.

For the purpose of relieving the strain on the gears 25 and 8 during their initial starting movement, I provide the base-plate 23' with the lug 28, projecting from the under side thereof, see Fig. 9, which said lug is intended to be inserted in the reduced slot 10, between the flanges 11 of plate 1, and engage with the walls of said slot in the event of the gears starting to separate, and hold the gears in meshing relation.

An examination of the bracket in Figs. ,6 and 7 will disclose that the connecting arms of the two parts 15 and 16 project at right angles from the body of the drag when the said bracket is in working position, which provides a connection of the two parts only on one side of the shaft 24. If advisable this connection of the parts 15 and 16 may be modified as shown in Fig. 10, where the part 15 is shown provided with superimposed arms 29 and 30 disposed parallel with the side wall of the drag, when in working position. and these arms are adapted to be fastened to upwardly and down wardly projecting lugs 31 from the bearing of said part 16.

In Figs. 5, 6 and 8 a shield 38 is shown,

which is designed to cover the gears S and 25, in the manner best seen in Figs. 5 and 6, which will protect the gears against any foreign substance entering between the teeth, which might have a tendency to break the same, and will also protect the operator when working-around the mechanism.

In Fig. 1 the body ofthe drag is shown disposed at an incline with the head end thereof resting on a receiving hopper A. As a means of adjusting the head of the drag on the hopper and also to prevent its accidental dislodgment therefrom, due to vibration or other causes, an arm 32 is pivoted at 33 to the side of the drag or plate 1; its forward end is formed with an offset 34: to engage the wall of the hopper A, and also provided with an extension 85, slotted as at 36, through which a bolt 37 operates, to provide for adjusting and locking the forward end of the arm 32 in different positions.
