Application filed September 28, 1918. Serial No. 256,046.

To all whom it may concern:

Be it known that I, WILLIAM J. NOBLE, a citizen of the United States, residing at Kearney, in the county of Buffalo and State of Nebraska, have invented certain new and useful Improvements in Demountable Driving Wheels for Motor-Oycles,.of which the following is a specification, reference being had to the accompanying drawings.

This invention relates to an improved demountable driving wheel for motor cycles,

and has for its primary object to provide improvedmeans for easily and quickly assembling the wheel in the machine frame and operatively connecting the same to the driving sprocket and the brake drum, or re movingsaid'wheel when necessary without disturbing the positions of the latter elements.

'It is a more particular object of my invention to provide in a motor cycle, separate shafts upon: which'the wheel, the driving sprocket and the brake drum are mounted, and means forqui'ckly coupling the wheel shaft to the sprocket and crank shafts, whereby the shafts are caused to rotate as a unit. 1 j i It is also a further object ofmy invention to provide a demountable wheel for motor cycles whichis relatively simple in its construction, strong and durable, and can be manufactured-at relatively small cost.

With the above and other objects in view, the invention consists in-the improved construction, combination and relative arrangementnofthe several parts as will be hereinafter "more: fully described, subsequently claimed andillustrated in the accompanying drawing in which similar reference characters designate corresponding parts; throughout the several views,and where1n:-

Figure 1 is an elevation illustrating the preferred embodiment of the invention; Fig. 2 is a'sectional view taken onthe line 22 ofFig. 1*; r

I Fig. 3 is a section taken on the line 3-3 of Fig.2; and

Fig. {lis a. fragmentaryerspective-view of oneof the coupling mem ers. 1 1

. .Refe-rring detail to the drawing, 5 designates the side-frame bars of a motor cycle, to (which. thembearingsao are bolted or otherwise rigidly-rsecured. Short, inwardly projecting shafts 7 and? 8-respec- ,tivfely arejournaled in these bearings. Upon the shaft. 7 the driving, sprocket? 9- is-keyed,

and upon the shaft 8 thebrake drum 10 is similarly secured. Upon the inner end of each of the shafts 7 and'8, adisk 11 is fixed, and each of said disks is provided in its perlphery at spaced points with the dovetail mortises or recesses l2.

l3 designates the drive wheel shaft, upon which the drive wheel 14 is keyed. To each endof this shaft, the disks 15 are fixed, said disks being complementary to the disks 11 and likewise each provided in its periphery with the spaced dove-tail recesses 16. The means for coupling the disks 11 and 15 together at each end of the wheel shaft 13 is identical, and therefore the detail descript on of one coupling means will suflice for both.

In the disk 15, suitably spaced, inwardly projecting guide pins 17 are fixed, upon which a metal ring or annulus 18 is loosely engaged for movement laterally toward or from the side face of the disk. To the coupling ring 18, the spaced outwardly proserted through the registering recesses, the

beveled side edges of the lugs having wedging engagement with the side edges of said recesses when the coupling ring 18 is closely engaged against the inner side face of the disk 15. l

. Each'of the coupling lugs 19 is provided in spaced relation to its free end andin the inner=facethere0f with a groove or channel 20. These channels are adapted to receive the locking fingers or extensions 22, which project radially from a plate 21 mounted upon the outer side face ofthe disk 11. This plate is formed with a series of spaced arcuate slots 23, through which headed studs or pins 24:, fixed in the disk, are engaged. These studs limit the 'rotativemovement of the plate 21 withrespectto the shaft or axis of the disk 11. The plate 21 ispreferably formed with a suitable handle, indicated at 25, whereby it may beshifted. In the movement of said plate in one direction, the fingers 22 are engaged in the grooves or channels" 20 in the ends of the lugs 19, the studs; 24 limiting suclr movement. The coupling lugs are, therefore, securely locked and held against longitudinal movement 111 the recesses of the coupled disks 11 and 15. The plate 21 is provided with an opening adapted to coincide with a threaded opening in the disk 11 to receive a screw 26, whereby the plate 21 is held in its locking position and the possibility of the release of the coupling members, owing to casual shifting movement of the locking plate, due to vibration, thereby prevented. In this manner, it will be seen that the shaft of the motor vehicle wheel-may be easily, quickly and securely coupled to the shafts 7 and 8, upon which the driving sprocket and the brake drum are mounted so that all of said shafts willrotate as a unit. Then it is desired to remove the wheel 14, it is only necessary to first remove the screws 26 and then shift the locking disks 21 so as todisengage the fingers 22 thereon from the grooves in the coupling lugs. The rings 18 are then forced inwardly upon the guide pins 17 and the lugs 19 disengaged from the recesses in the disks 11. The shaft 13 with the vehicle wheel la may then be bodily lifted and removed from the machine frame without disturbing the mounting or arrangement of the sprocket wheel and brake drum.

From the foregoing description, taken in connection with the accompanying drawing, it is believed that the construction, manner of use, and several advantages of my invention will be clearly and fully understood. The device provides means whereby the drive wheel of a motorcycle can be easily and quickly removed when repairs are necessary and as readily replaced in position and coupled to the sprocket wheel and drum shafts. Thecoupling means, as above described, is exceedingly strong and durable,

and capable of withstanding the severe strains incident to the application of the brake, such coupling means effectually preventing any possibility of relative rotation of the shafts which would render the brake inefiective. The several partsof the device as herein described may be readily produced at small cost and easily and quickly assembled. It will be apparent that the disks Hand 15 above referred to can be of any desired size and a greater or less number of the coupling lugs 19 provided than as herein indicated. The several other elements employed are likewise susceptible of many minor modifications in their form and relative proportions, and I accordingly reserve the privilege of adopting all such legitimate changes as may-be fairly embodied within the spirit and scope of the invention as claimed.
