To all whom it may concern:

Be it known that I, ANDREW CRAWFORD STARK, a subject of the King of GreatBritain, and resident or the city of Toronto, county of York, Province of Ontario, inthe Dominion of Canada, have invented certain new and useful Improvements in Supports for Motorcycles and the like, of which the following is a specification.

The invention relates to improvements in a support for motorcycles and the like as described in the present specification and illustrated in the accompanying drawings that form a part of the same.

The invention consists essentially of the novel construction and arrangement of parts whereby a pair of auxiliary wheels mounted on the under side of the central portion of themachine frame are adapted to be brought into engagement with the ground for supporting the machine in its upright position.

The objects of the invention are to provide a means for supporting the machine in an upright position, to facilitate traveling through crowded thoroughfares where it is frequently necessary to stop the machine, to insure safety to rider and pedestrians alike, and generally to provide a support for inotorcycles and the like which will be inexpensive to manufacture, simple to operate, durable and efficient.

In the drawings Figure 1 is a perspective view of a portion of a motorcycle showing the auxiliary wheels out of engagement with the ground.

Fig. 2 is a perspective view showing the supporting wheels as they appear when in engagement with the ground.

Fig. 3 is a rear view of the auxiliary wheels and the carriage therefor.

Fig. 4 is an end view of the device shown in Fig. 3.

Like numerals of reference indicate corresponding parts in each figure.

Referring to the drawings, the cross rod 1 which connects the rear ends of the foot boards 2 and 3 is utilized in the present invention to carry the frame of the auxiliary supporting wheels, said frame consisting of a pair of bars 4 pivotally mounted on said rod, one adjacent to each end thereof, a pair of braces 5 secured at their lower ends to said bars 4 and extending inwardly and loosely encircling said rod 1, and a cross piece 6 rigidly secured at each end to a brace 5 adjacent to said rod 1.

Patented Sept-2,1919.

7 and dare the auxiliary wheels mounted on axles 9 pro ectlng inwardly from the outerends of the bars4, said bars beingof 'suohalength that when forced to averucai position the rear wheel 10 of the machine will be raised very slightly from the ground and when said bars are forced slightly forwardly past their vertical positions the weight of the machine will prevent their returning to their former positions until manual pressure is applied.

The wheels 7 and 8 are held normally out of engagement with the ground by means of springs 11 secured at their lower ends to the cross piece 6 and at their upper ends to the member 12 of the frame of the machine.

The wheels 7 and 8 are adapted to be brought into engagement with the ground by means of pressure brought to bear on a foot lever 13 connected at one end to the cross piece 6 by a brace 14 and at the other end connected to a bar 4 by a brace 15, said lever being positioned, when the wheels 7 and 8 are out of engagement with the ground, slightly above and to the rear of the foot board 3 so as to be readily operated by a simple backward IHOVBIIIGIIt of the foot of the rider.

In the operation of the invention the ma chine is supported in a vertical position by simply pressing backwardly on the foot lever 13 until the bars 4 have passed their vertical positions thus bringing the wheels 7 and 8 into engagement with the ground, one at each side of the machine.

The wheels 7 and 8 may be returned to their normal positions by a slight forward pressure on the foot lever 13 or by raising the rear wheel of the machine sufficiently to admit of the bars 4 passing their vertical positions when the springs 11 draw them up wardly and hold them.

This device will be found of the utmost value when riding through crowded thoroughfares where it is frequently necessary to stop, as at street cornersand the like, as the wheels 7 and 8 may be left in their down positions and the machine stopped and started at will without the necessity of the rider dismounting or having to stop his engine.

It will also be found an advantage when riding over extremely rough roads in which in combination, a frame, foot boards carried by said frame, cross rod connecting said foot boards on the under sides thereof, a pair of bars pivotally secured one at each end of said cross rod and carrying Wheels, braces secured to said bars and extending inwardly and loosely encircling said cross rod, a cross piece connecting said braces, springs secured at their lower ends to said cross piece and .10 at their upper ends to the machine frame and holding said Wheels normally free of the ground and a foot lever secured to said cross piece and to one of said bars and adapted on operation to force said Wheels into engagement With the ground.

Signed at Toronto, Ontario, this 18th day of February, 1918.

ANDREW CRAWFORD STARK.
