-To all whom, it may concern:

Be it known that I, HARRY T. KINGSBURY, a citizen of the United States, residing at Keene, in the county of Cheshire, State of New Hampshire, have invented certain new and useful Improvements in Inertia-Wheel Toys, of which the following is a description, reference being had to the accompanying drawings and to the figures of reference marked thereon.

My invention relates to improvements in I self-driven toys, and more particularly to that class of wheeled toys which are driven by an inertia-wheel.

The object of my invention is to improve the driving connection between the inertiawheel and the running-wheels; and it con sists in certain novel features of construction and combination of parts, which will be hereinafter fully set forth in the description and pointed out in the claims.

In the drawings I have shown only so much of a toy vehicle as is necessary to understand my invention.

Figure 1 is a side elevation, partly in section, showing the running-wheels and the driving mechanism therefor of a portion of a wheeled toy. Fig. 2 is a plan view thereof, the main frame being shown in dotted lines. Fig. 3 is a detail showing in side elevation the main frame and the adjustable carrier, the adjustable carrier being broken away at the right-hand end to show the adjusting-screw therefor. Fig. 4 is a sectional view on the line so a: in Fig. 3.

In the preferred form of my invention I provide a main frame 1, which slidingly supports a carrier 2. Pivotally supported in the carrier 2 is an inertia wheel 3, which is fast to the axle 4, supporting the same. Rigidly secured to the axle 4 is a gear 5, which 7 meshes with a gear 6 on the shaft 7, rotatably mounted in the carrier 2 and carrying a sprocket-wheel 8. At the rear of the main frame are depending supports 9, which are perforated to receive the axle 10, on which are secured the running-wheels 11 11. Also fast to the axle 10is a sprocket-wheel 20, which is operatively connected to the sprocketwheel 8 by a chain 12. The carrier 2 is slid ingly supported from the main frame by the keepers 13 and 14, which are riveted to the main frame or may be secured by any other means. The forward end of the frame. is bent downwardly and is provided with an opening 15, which receives a screw-bolt 16.

Said bolt is threaded into the forward end of the carrier and regulates theposition of sald carrier relatively to the main frame. It often occurs through wear of the part that the sprocket-chain becomes loose, and it will readily be seen that by turning the screw 16 the carrier which supports theinertia-wheel, gears, and sprocket-wheel 8 may be moved and the chain thus put under proper tension.

The operation of my device will be apparent from the above disclosure. The runningwheels are first turned by hand or by placing the same in contact with a surface and rapidly moving the same. The movement of these wheels is transmitted, through the sprocket'20 and chain 12, to the sprocket 8, and in turn through the gears 6 and 5 to the inertia-wheel, and likewise movements of the inertia-wheel are transmitted to the running-wheels. It will be noted that the movement of the running-wheel is greatly multiplied in the inertia-wheel, so that the same may be made to turn rapidly.

The advantages of my device will be apparent. All movements of the runningwheels are positively transmitted to the inertia-wheel, and vice versa. In the present inertia toy the motion is transmitted between the running-wheels and inertia-wheel by frictional contact, which causes much lost motion. I find by my arrangement of parts no motion is lost, and the inertia-wheel may be given sufficient momentum to propel the vehicle.

Having thus described my invention, I claim as new and desire to secure by Letters Patent of the United States 1. A wheeled toy comprising in combination, a main frame, running-wheels carried thereby, a carrier slidingly supported by said main frame, an inertia-wheel mounted in said carrier, means for operatively connecting said running-wheel and inertia-wheel including a sprocket-chain and means for adjusting the carrier.

2. A wheeled toy comprising in combination, a main frame, running-wheels carried thereby, a carrier slidingly supported by said main frame, an inertiawheel mounted in said carrier, a sprocket-wheel connected to the running-wheels, a second sprocket geared to the inertia-wheel, a chain connecting said sprockets and means for adjusting the carrier.

3. A wheeled toy comprising in combination, a main frame, running-wheels carried thereby, a carrier slidingiy supported by said main frame, an inertia-Wheel mounted in said carrier, a sprocket-wheel connected to the running-wheels, a second sprocket geared to the inertia-Wheel, a chain connecting said sprocket, said main frame having a downwardly-projecting portion, a screw carried thereby and threaded in the carrier whereby said carrier may be adjusted.

4. A wheeled toy, comprising in combination, a main frame havingdepending sup ports, running-wheels carried thereby, a carrier adjustably supported by said main frame, means for adjusting said carrier, an inertia-wheel mounted in said carrier, a sprocket-wheel connected to the runningwheels, a second sprocket-wheel mounted in said carrier, a chain connecting said sprocketwheels, gearing between said second sprocketwheel and said inertia-wheel.

5. A wheeled toy comprising in combination, a main frame, supports depending therefrom, keepers carried by said frame, a carrier sliding in said keepers, running-wheels carried by said supports, an inertia-wheel mounted in said carrier, a sprocket-wheel connected to the running-wheels, a second sprocket-wheel mounted in said carrier, a

chain connecting said sprocket-wheels, gear ing between said second sprocket-wheel and said inertia-wheel, said main frame having a downwardly-projecting portion, a screw carried thereby and threaded in the carrier, whereby said carrier may be adjusted.

6. A'wheeled toy, comprising in combinationa main frame, supports depending therefrom, a shaft freely carried in said sup orts, running wheels on said shaft, U sfiaped brackets .carried by said frame, a carrier slidingly supported in said brackets, an inertiawheel mounted said carrier, a sprocketwheel connected to the shaft of the runningwheels, a second sprocket-wheel mounted in said carrier, a chain connecting said sprocketwheels, gearing between said second-sprocketwheel and said mertia-wheel, said main frame having a downwardly-projecting portion, a screw carried thereby and threaded'into said carrier, whereby said carrier may be adjusted.

In testimony whereof I .afii my signature in presence of two witnesses.
