SELECTIVELY ENGAGEABLE AND DISENGAGEABLE DRIVE FOR WHEELED
DEVICES SUCH AS GRAIN AUGERS OR THE LIKE
BACKGROUND OF T~E INVENTION
This invention relates to new and useful improve-ments in devices for selectively driving a device and al-though it is primarily for use with a grain auger assembly, nevertheless it can readily be adapted for use on other farm implements and the like in which there is a require-ment to move such implements relatively short distances ln~tead of having to hi~ch them to a tractor or other source of motive power.
For example, with the relatively large grain auger assemblies in common use on grain farms and the like, it is often de~irable to manipulate or move the grain auger assembly from one location to another in order that the load~ng or unloading of ~rain to or from grain storage bins, may be undertaken. Such relatively large grain auger as-~emblies are difficult to manoeuver manually and many at-tempts have been made to incorporate additional drive wheels which can be engaged with the ground in order to facilitate this manipulation in relatively confined areas.
Such devices suffer from several disadvantages, the principal one of which is the fact that the selectively en-. ~
1~52435 engageable drive wheel has to be mounted in a frame suspend-ed from the undercarriage of the grain auger assembly, it has to be provided with means to raise and lower the wheel out of and into contact with the ground, it has to be pro-vided with a castoring or steering assembly so that the operator may direct the movement of the grain auger assem-bly acros~ the ground, and it has to be provided with a source of power, the control of which is by the operator who is attempting to steer the device as well as to control the speed a~d final positioning of the assembly.
SUMMARY OF THE INVENTIO~
The present invention overcomes these disadvantages by providing a hydraulic motor which is mounted upon a sim-ple bracket assembly on the inside of each of the ground en-gaging wheels of the undercarriage of a grain auger assembly or other farm implement. The two hydraulic motors are con-nected to a ~ource of hydraulic fluid under pressure and may easily be controlled by means of conventional valves with the ~teering being controlled by sending fluid to one wheel or the other.
Furthermore, means are provided to operatively enga-ge or disengage the hydraulic motor with the ground engaging wheels so that the hydraulic motors may either drive the wheels or, alternatively, may be disengaged so that the im-plement may be towed by a tractor in the usual way.
In accordance with the invention there is pro-vided selectively engageable drive means for a ground en-gaging wheel mounted upon an axle component and comprising in combination a support bracket, a source of power mounted on said bracket, means rotatable by said source of power, further means on said ground engaging wheel selectively engageable and disengageable with said means rotatable by said source of power, to selectively drive said ground en-gaging wheel, and means mounting said bracket to said axlecomponent for selective engagement and disengagement of said means rotatable by said source of power, to said fur-ther means on said ground engaging wheel, said means mount-ing said bracket to said axle including means whereby said bracket and said source of power can be raised and lowered relative to said axle component, to engage and disengage said source of power with said ground engaging wheel, said means mounting said bracket to said axle com-ponent including a vertically situated, fiY~ed member mounted upon said axle component, said bracket being mounted for slidable vertical movement upon said fixed member and lock means selectively engaging with said fixed member to detachably lock said bracket in the uppermost position with said source of power operatively engaging 1~5243s _ 3A
said ground engaging wheel.
Another advantage of the invention is to pro-vide a device of the character herewithin described which is easily attached or detached from conventional ground engaging wheel assemblies via the axle component thereof.
A still further advantage of the invention is to provide a device of the character herewithin described which is simple in construction, economical in manufac-ture and otherwise well suited to the purpose for which it is designed.
With the foregoing in view, and other advantages as will become apparent to those skilled in the art to which this invention relates as this specification proceeds, the ~152435 invention is herein described by reference to the accompany-ing drawings forming a part hereof, which includes a des-cription of the preferred typical embodiment of the princi-ples of the present invention, in which:

DETAILED DESCRIPTION
Proceeding therefore to describe the invention in detail, Figure 1 shows the inside view of a ground engaging wheel assembly collectively de~ignated 10 including a wheel rim component 11 having a pneumatic tire 12 mounted thereon with the rim being secured to a conventional back plate 13 by means of wheel bolts 14, with the hub being journalled for rotation upon a fixed spindle 15 (see Figure 2) support-::' " f-: I
~15Z435 ed upon the end of an axle beam 16, all of which is con-ventional. In the claims, the axle beam 16 together with the spindle 15 is defined as an axle component.
Supporting structure collectively designated 17 is provided and secured to the axle beam 16 adjacent the out-er end thereof and adjacent the wheel assembly 10. In this embodiment, the supporting structure includes a short length of channel 18 extending transversely across the wheel beam 16 and being clamped to the wheel beam by means of a base plate 19 spanning the axle beam 16 upon the underside there-of and being secured to the channel by means of nut and bolt as~emblies 20.
A support bracket is provided collectively designa-ted 21 and in this embodiment, the support bracket includes a substantially horizontally situated base plate 22 with a vertical flange 23 extending upwardly from the outer edge thereof. It may be formed from a length of angle iron suit-ably ~haped as illustrated with the horizontal base flange 22 facing inwardly away from the wheel assembly 10. A hy-draulic motor 24, of conventional construction, is bolted to the lnner surface of the vertical flange 23 by means of bolts 25 extending through the open ended slots 26 provided on each side of the hydraulic motor (only one of which is shown).
The support bracket together with the hydraulic motor are supported on the support structure by means of a vertically situated fixed member 27. In the present embodiment, this fixed member takes the form of a bolt acting as a spindle or shaft, with the bolt extending through an aperture 28 formed through the horizontal flange 22 of the support bracket and adjacent one end thereof as clearly shown. The mounting of the support bracket and the hydraulic motor upon the bolt 27 is such that the support bracket and motor may be moved vertically up and down the bolt from a position defined as a ground engaging wheel driving position illustrated in Figures 1 and 3 to a ground engaging wheel disengaged position (not illustrated) and vice-versa.
Mbans are provided to selectively maintain the bracket and motor in the ground engaging driving position, said means taking the form of a spring clip or lock pin 29 engageable through an aperture bracket (not illustrated) in the bolt 27 so that the bracket rests upon the lock pin 29 when in the position shown in Figures 1 and 3. However, if the lock pin 29 i8 disengaged, the support bracket and the hydraulic motor may be dropped downwardly to rest upon or adjacent to the web 18A of the channel 18 forming part of the supporting structure 17.
llSZ435 The hydraulic motor extends through an aperture in the vertical flange 23 of the support bracket an~ is provided with means rotatable by the hydraulic motor.
In the preferred embodiment, this takes the form of a sprocket wheel 30 rotatable by the motor when the motor is operating.
Means are provided on the wheel assembly 10, se-lectively engageable by the sprocket 30 in order to selec-tively rotate the ground engaging wheel assembly 10 and Figure 1 ~how~ a length of sprocket chain 31 formed in a circle and secured to adjacent the rim 32 of the rim com-ponent 11 of the wheel assembly as by welding or the like, and it should be observed that this chain circle 31 is po-sitioned concentrically with the axis of rotation of the wheel.
When the bracket assembly and motor are in the ground engaging wheel driving position illustrated in Figu-re~ 1 and 3, the sprocket is operatively engaged with the inner ~urface of the chain circle 31 so that rotation of the hydraulic motor in either direction, rotates the ground engaging wheel. However~ when the lock pin 29 is disengaged, the ~upport bracket and motor drop downwardly thus disengag-ing the sprocket 30 from the chain under which circumstances the assembly is said to be in the ground engaging wheel dis-l~5Z43S
engaged position.
Means are provided to selectively guide the move-ment of the support bracket and the hydraulic motor along the length of the shaft or spindle 27, said means taking the form of a retaining plate 32 bolted by adjacent one end thereof to the innermost vertical flange 18B of the channel 17 and extending upwardly to engage the inner side or edge 22A of the horizontal flange 22 of the support bracket as clearly illustrated. This ensures that the sprocket 30 engages the chain circle 31 when it is moved upwardly.
However, it may be desirable to swing the entire assembly clear of the wheel when it is desired to tow the implement by means of a tractor or any other conventional means under which circumstances the bolt 33 clamping the retainer plate 32 in position, may be loosened so that it can be swung downwardly clear of the support bracket thus enabling the support bracket after it has been lowered clear of the chain circle 31, to be swung inwardly or pi-voted upon the bolt 27 so that it lies substantially paral-lel with the axle beam 16.
Figure 2 shows an alternative drive method which includes an internally toothed ring gear 34 bolted to the rim of the wheel assembly 10 by means of bolts 35 also con-centrically with the axis of rotation of the wheel and having a gear 36 operatively secured to the spindle 37 of the hydraulic motor and selectively engageable with the internally toothed gear 34.
Figure 4 shows a schematic view of the hydraulic circuit which includes an hydraulic pump 38, a fluid re-servoir 39 operatively connected thereto, an adjustable speed and reversing valve assembly which is conventional, and the two hydraulic hoses 41 and 41A extending from the hydraulic motor to the selector valve 40, all of which is conventional.
In operation, it will be appreciated that most im-plements are provided with two ground engaging wheels, one upon each side of the undercarriage thereof ~not illustra-ted) BO that an embodiment of the invention is secured to each end of the axle beam 16 adjacent each wheel. The ope-rator i~ provided with two selector valve assemblie~ 41 for each whoel whereby he can control the speed and direction of the drive to each thu~ enabling him to manipulate the implement readily and easily with the pump being driven ei-ther by a source of power (not illustrated) on the implement or an auxiliary one selectively connectable thereto (also not illu~trated~.
Since various modifications can be made in my in-vention as hereinabove described, and many apparently wide-ly different embodiments of same made within the spirit and scope of the claims without departing from such spirit and ~cope, it is intended that all matter contained in the ac-companying specification shall be interpreted as illustra-tive only and not in a limiting sense.

Supporting structure collectively designated 17 is provided and secured to the axle beam 16 adjacent the out-er end thereof and adjacent the wheel assembly 10. In this embodiment, the supporting structure includes a short length of channel 18 extending transversely across the wheel beam 16 and being clamped to the wheel beam by means of a base plate 19 spanning the axle beam 16 upon the underside there-of and being secured to the channel by means of nut and bolt as~emblies 20.
A support bracket is provided collectively designa-ted 21 and in this embodiment, the support bracket includes a substantially horizontally situated base plate 22 with a vertical flange 23 extending upwardly from the outer edge thereof. It may be formed from a length of angle iron suit-ably ~haped as illustrated with the horizontal base flange 22 facing inwardly away from the wheel assembly 10. A hy-draulic motor 24, of conventional construction, is bolted to the lnner surface of the vertical flange 23 by means of bolts 25 extending through the open ended slots 26 provided on each side of the hydraulic motor (only one of which is shown).
The support bracket together with the hydraulic motor are supported on the support structure by means of a vertically situated fixed member 27. In the present embodiment, this fixed member takes the form of a bolt acting as a spindle or shaft, with the bolt extending through an aperture 28 formed through the horizontal flange 22 of the support bracket and adjacent one end thereof as clearly shown. The mounting of the support bracket and the hydraulic motor upon the bolt 27 is such that the support bracket and motor may be moved vertically up and down the bolt from a position defined as a ground engaging wheel driving position illustrated in Figures 1 and 3 to a ground engaging wheel disengaged position (not illustrated) and vice-versa.

When the bracket assembly and motor are in the ground engaging wheel driving position illustrated in Figu-re~ 1 and 3, the sprocket is operatively engaged with the inner ~urface of the chain circle 31 so that rotation of the hydraulic motor in either direction, rotates the ground engaging wheel. However~ when the lock pin 29 is disengaged, the ~upport bracket and motor drop downwardly thus disengag-ing the sprocket 30 from the chain under which circumstances the assembly is said to be in the ground engaging wheel dis-l~5Z43S
