Application iled November 16v, 1915. Serial No. 61,810.

To all whom it may concern.'

Be it known that I GEORGE A. KING, a citizen of the United States, residing at Maple Falls, in the county of Whatcom and Stateof Washington, have invented certain new and useful Improvements in Driving Mechanism g. and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to new and useful improvements in propelling and r'guiding means for vehicles andprimarily for use in connection with a vehicle adapted to carry breaking or other forms of` plows, and my prime; obj ect is to provide means for turning thevehicle in a very smallradius.

A` further, object is to provide means for. applying,` the power in. such manner as-to propel thevehicle forwardly or rearwardly.

A further object is to provide means for rotating the forward axle to guide the vehicle.

And a further object` is to provide means for` applying power to both axles of the vehiclesimultaneously or to the forward axle singly.

Other objects and advantages will be hereinafter set forth andmore particularly pointed outv in the accompanying specification.

In the accompanying drawings which are made a part of this application.

Figure 1 is a detail sectional view as seen on line 1,-1 of Fig. 2.

Fig. 2 is a sectional view as seen online 2-2 of Fig. 1, and

Fig. 3 isa detail top plan view ofithe pro` peiling an'd guiding mechanism.

Referring to the drawings in which similar reference numerals designate corresponding parts throughout the several' views, 1 and-2 indicate the front and rear supporting wheels respectively for the vehicle which are mounted upon axles 3 and 4 respectively, each axle. being preferably surrounded by a tubular casing 5- and 6, the casing 5 beingwprovided `with an upwardly extending, yoke 7, while the. casing 6 is provided with a horizontally extending yoke 8.

Connected to the yoke 8 at its longitudinal center is asleeve 9 through -which extends a shaftllO, the rear end of the shaft having agear'll which meshes with asimilar gear 12 on the rear axle.4,rwhile to lthe forward end of the shaft 10 is movably secured a gear 13fwhich meshes with a similar gear 14 carried bv a vertically extending shaft 15.

Mounted upon anelongated collar 16 surrounding the inner end of the shaft 10 is a platform 17 which is adapted to form a support for any suitable form of combustion engine (not shown) and also for the driver,

av gear 18 beingl mounted upon a shaft 19 to receive the power from the motor, the ends of the shaft 19being rotatably mounted in av yoke 20.

The shaft 19 has attached thereto a gear 24 which meshes with an elongated pinion 25 carried by a shaft 26, said shaft being adjustably mounted in the upper ends of the yoke 20, said yoke being supported by an arm 27 extending from the sleeve 28 surrounding the shaft 15, and in view of the elongatedpinion 25, the shaft may be moved a suitable distance longitudinally in either direction without being disengaged from the geary 24.

The sha-ft 26 has attached thereto

beveled gears

29 and 30 which are adapted to mesh with the opposite edges of a bevel gear 31 carried by a horizontally extending shaft 32, said-gearsbeing. employed for driving the wheels of the vehicle forwardly lor rearwardly.

The shaftv 26 is moved longitudinally to bring, either ofthe

gears

29 or 30 into mesh with theV gear 31 by pivoting a lever 33 to the yoke 20, one endof the lever engaging between collars 34 on the shaft 26 which will permit said shaft to rotate but cause the shaft to movel longitudinally when the lever is rocked on its pivot, the opposite end ofthe lever having a latch 35 which coperates with the rack 36 for holding the lever in adjustedposition and by forming a plurality of notches inthe rack, both of the gears 29 and'30 may be locked out of engagement with the gear 31, thus stopping the. propulsion of the vehicle, although the engine may still remain running.

The shaft 32 extends forwardly from the gear3-1 and has a bevel gear 37 fixed thereto which meshesr with a similar gear 38 attached to the upper end of the shaft 15 thereby imparting rotating movement to the rearaxle 4 so long as the gear 13 lis in mesh with the gear 14, butiwhen it is desired to disconnect the driving power from the rear n axle, thelever 39 is thrown forwardly thereby sliding the gear 13 rearwardly on the shaft 10 and disconnecting the same from the gear 14, a suitable rack and latch 41 being provided for holding the lever 39 1n its adjusted position.

Y The forward end of the shaft 32 has a piny ion 42 fixed thereto which meshes with the pinion 43 fixed to the upper end of a shaft 44, said shaft extending through a tubular casing 45 carried by the yoke 7, the lower endl of the shaft 44 having a pinion 46 attached thereto which meshes with the pin-V ion 47 fixed to the front axle 3, thus imparting rotating movement to said axle when the gear 31 isV rotated.

Attached to the connecting bar of the yoke 7 is a circular rack 48 with which meshes a gear 49 carried by a shaft 50, said shaft finding a bearing in the extension 51 of the casing 53 carying the shaft 32.

Fixed to the upper end of the shaft 'is a bevel gear 53 with which meshes a bevel pinion 54 attached to one end of a steering shaft 55, the opposite end of the steering shaft having a steering-wheel 56 which may .l be readily grasped to operate the steering mechanism.'

When the vehicle is traveling forwardly the power is preferably applied between the front and rear axles by connecting the gear 13 with the gear 14 and the Vgear 29 with the gear 31, but whenithe end of the field is Y reached and it is desired to ina-ke a short or abrupt turn, the lever 39 is operated to disengage the gear 13 from the gear 14, there-v by disconnecting the power from the rear axle 4 and by operating the hand wheel 56 to throw vthe forward wheels in position at right angles to the rear wheels or to a greater extent if desired, the vehicle may be turned from end to end yin a very limited space, thus rendering the device particularly applicable for use in a small plot of ground, although it will be clearly understood that it can be used equally as well in a larger plot of ground. If it is desired to move the vehicle rearwardly, the latch 35 is disengaged from the rack 36 and the free end of the lever 33 thrown inwardly its full distance which will move the gear 30 into engagement with the gear 31, thereby reversing the rotati-on of the axles 3 and 4 and causing the y L vehicle to travel rearwardly.

When it is desired to stop the movement of the vehicle in either direction without stopping the operation of the engine, the lever 33 may be swung on its pivot to a point substantially midway between its extreme movement which will disengage yboth of the

gears

29 and 30 from the gear 31, thus disconnecting the motor from the driving gears of the vehicle and permitting the vehicle to stand idle while the motor is still rotating.

It will likewise be seen that by connecting the various casings together by couplings, as shown, a very rigid frame construction will be provided and by attaching the platform to the sleeve 16 which is rotatable on the shaft l0 the wheels of the vehicle may pass over objects without affecting the position of the motor with respect to the gear 18.

Having thus fully described my invention what I claim as new and desire to secure by Letters Patent of the United States, is
