No. 204,534 6 Claims. (Cl. 198120.5)

My invention relates to new and useful improvements in motor mount assemblies for grain augers.

Grain augers, particularly relatively long grain augers are usually provided with hoist means adapted to raise and lower the discharge end and this means that the motor mount assembly normally associated with such grain augers has to be adjusted in position in order to maintain it substantially level irrespective of the angle of inclination of the auger tube.

Furthermore it is conventional to provide a clutch for the drive between the source of power carried on said motor mount and the drive for the auger, in order that the motor may be started in a disconnected condition from the auger tube and to enable the auger tube to cease discharging without having to stop the motor.

By providing a motor mount assembly with a strut extending between the base thereof and the auger tube, I am able to maintain the motor mount assembly, together with the source of power thereon, relatively horizontal irrespective of the position of the auger tube. Furthermore, by providing an eccentric mounting for the motor mount assembly to the grain auger, I eliminate the necessity for a clutch as it is easy to loosen and tighten the belt merely by a flip of a lever in order to disconnect the motor from the drive of the auger.

The principal object and essence of my invention is therefore to provide a device of the character herewithin described in which the motor mount assembly is maintained in a substantially horizontal position at all times.

Another object of my invention is to provide a device of the character herewithin described which eliminates the necessity for a built in clutch due to the provision of an eccentric mounting for the motor mount assembly.

A yet further object of my invention is to provide a device of the character herewithin described which includes means to lock the motor mount assembly in the belt loosened or belt tightened position, by providing an over center movement for the eccentrics which rotate through at least 180 degrees.

A still further object of my invention is to provide a device of the character herewithin described which is simple in construction, economical in manufacture, and otherwise well suited to the purpose for which it is designed.

With the foregoing objects in view, and such other objects and advantages as will become apparent to those skilled in the art to which this invention relates as this specification proceeds, my invention consists essentially in the arrangement and construction of parts all as hereinafter more particularly described, reference being had to the accompanying drawings in which:

FIGURE 1 is a view, partly in side elevation and partly in vertical section, showing a conventional grain auger embodying the motor mount of the invention, the auger being illustrated in a lowered position;

FIGURE 2 is a fragmentary view, similar to that shown in FIGURE 1 but illustrating the anger in a raised position;

FIGURE 3 is a fragmentary elevational view on an enlarged scale of the motor mount;

FIGURE 4 is a transverse sectional view, taken substantially in the plane of the line 4-4 in FIGURE 3;

FIGURE 5 is a fragmentary top plan View of the motor mount; and

FIGURE 6 is a vertical sectional'view of the motor mount in the belt loosened position.

3,181,687 Patented May 4, 1965 In the drawings like characters of reference indicate corresponding parts in the different figures.

Proceeding therefore to describe my invention in detail, reference should first be made to FIGURE 1 in which I have illustrated a conventional grain auger tube 10 within which is provided an auger flight 10'. A gear box '11 is secured to the tube and drives shaft 12 which extends to gears 13 thus providing drive to the auger flight.

The auger tube 10 is normally mounted upon a front A frame 14 and a rear A frame 15, both converging to a common locus 16 which is normally the wheel axle upon which ground engaging wheels 17 are provided.

The rear A frame 15 is normally pivoted to the auger tube as at 18 whereas the front A frame 14 is slidably attached to the underside of the auger tube and slides along due to the action of a conventional hoist mechanism (not illustrated) so that the auger tube can take up a lowered position shown in FIGURE 1 or, alternatively, a raised position shown in FIGURE 2.

Under these conditions, of course, it is desirable that the source of power 19 situated upon motor mount assembly 20, is maintained substantially horizontal. The motor mount assembly 20, shown in detail in FIG. 2, consists of the upper plate 21 upon which the source of power may be attached by bolts through apertures '22. Depending side flanges 23 are provided, each side flange having a tubular bearing 24 as clearly shown.

Secured to the underside of upper plate 21 is a pair of depending pivot lugs 25 comprised of a pair of spaced and parallel plates 26 maintained in this relationship by means of spacer 27. The upper ends of these plates are outturned as at 28 and secured to the underside of the plate 21 by welding or similar means.

-A further pivot lug 29 is secured to the underside of the auger tube adjacent the point 1 8 and a strut 30 extends between pivot lugs 25 and 29. The attachment at both ends is similar but only the lower end is detailed. This consists of a screw threaded T-bolt 31, the cross bar 32 of which engages apertures within the lower ends of the plates 26 and the shank is screw threadably engaged within the end of the strut 39. This permits initial adjustment to be made in order to level the plate 21.

Referring back to the bearings 24 within the side flanges 23 of the motor mount, I have provided a mounting axle 33 extending therethrough and this mounting axle has secured thereto a pair of eccentrics 34 which are rotatable within the bearings 24. The axle 33 projects from the motor mount and is supported by frame members 37 of the rear A frame 15.

From the foregoing it will be appreciated that a linkage connection is provided between the rear A frame 15, the strut 30 and the pivot lugs 25 and 25, so that irrespective of the position of the auger tube 10, the motor mount plate is maintained substantially horizontal.

A belt 38 extends from the source of power 19, to a drive pulley 39 on the gear box 11 of the auger tube assembly and instead of providing a ciutch to connect and disconnect the source of power to the drive, attention is directed to the aforementioned eccentrics 34 secured to axle 33.

It will be observed that a crank arm 40 is formed on one end of the axle 33 and if the crank arm is in the position shown in FIGURE 6, then the motor mount assembly is tilted to the right (with respect to the drawings) thus slackening belt 38 and permitting the motor to operate without driving the auger tube flight.

However, if the lever 40 is rotated through more than degrees in the direction of arrow 41, to take up the position shown in FIGURE 3, the rotation of the eccentrics forces the motor mount assembly to its horizontal position shown in FIGURE 3 thus tightening the r a i g 3,181,687

3 belt and acting'a's a' clutch 'to connect the source of power to the auger'flight, I a V V I Due to the fact that the crank arm 40 passes'through at least v180 degrees, an over center action of the eccentricsis provided. However, it .is necessary to limit the rotation of this crank arm and in this connection I provide a pin 42 extending radially from the axle 33 at a position in between the plates 26 and it Will be observed that this pin engages the underside of plate 21 when t the crank arm 40 is in either the belt tightened or belt loosened position. a I
