1 '0 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 self-driven wheeled toys, and more especially 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 consists 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. I
Figure 1 is a vertical section of a wheeled toy embodying my invention. view thereof on the line 00 m of Fig. 1.
Only as much of the toy vehicle has been illustrated in the drawings as is necessary to understand my invention.
In the preferred form of my invention I provide a frame 1 with downwardly-extending lugs 2 3, which serve as supports or bearings for the running-wheels. I have shown these lugs as perforated to receive the axle or shaft of the running-wheels. A more elaborate bearing may be used, if desired. Rigidly mounted on the axle or shaft 4 and near each end thereof are the running-wheels 5. Intermediate the ends of said axle or shaft is a gear-wheel 6, fastened thereto so as to turn or rotate with the axle. Mounted in lugs projecting downwardly from the frame 1 is an inertia-wheel 9. Said inertia-wheel is rigidly fastened to an axle or shaft 10, which is also provided with a drum 8. Pivotally mounted on the axle or shaft lc are two independentlymovable frames or carriers 12 and 13. Each frame carries a gear-wheel 14 and 15, which mesh with the gear-wheel 6, rigidly connected to the axle of the running-wheels, so that all movement of the running-wheels is imparted to the gears 14 and 15, and vice versa. Fast on the axle 16, which supports the gear 14, is a friction wheel 17; which normally rests in contact with the drum 8, the loca- Fig. 2 is a plan.
tion of the axle 16 relative to the pivotal support of the frame or carrier 12 being such v that the friction-wheel will engage the drum at a point between the vertical and horizontal radii of the drum. By this arrangement of parts any downward movement of the carrier 12 will cause the friction-wheel to firmly gripv the drum and transmit more efficiently the rotary motion of the running-wheels to the inertia-wheel. The carrier 13 is provided with a friction-wheel 18, similarly located below the drum 8. and said wheel 18 serves to impart the rotary movement of the inertiawheel to the running-wheels. A suitable spring 19 connects the carriers 12 and 13 and normally holds the friction-wheels in contact with the drum 8.
The operation of my improved mechanism will be apparent from the above, description. By turning the running-wheels either by the hand or by placing said wheels in contact with asurface and rapidly moving the vehicle along the same the rotary movement of the wheel is transmitted through the gear-wheel 6 to the friction-wheel 17 and through the wheel 17 and drum to the inertia-wheel. It will be noted that .the rotation of the gear-wheel 6 tends to carry the frame 12 around with it, and thereby greatly increase the pressure of the friction-wheelon the drum. This increased pressure increases the efficiency of transmission from the friction-wheel to the drum and makes it possible to quickly give a high velocity to the inertia-wheel. In transmitting the power stored in the inertia-wheel to the running-wheels to propel the vehicle the effeet is directly opposite. The gear-wheel 15 has a tendency to climb on the gear-wheel 6, and thus raises the frame or carrier 13 and increases the pressure of the friction-wheel 18 on the drum. It will be noted that when the inertia-wheel becomes the driving means the rotation of the friction-drum 8 tends to lift the friction-wheel, turning the frame counterclockwise against the action of the spring. Likewise when the driving-wheels are storing up power in the inertia-wheel the tendency is to turn the frame 13 about the shaft 4 in a clockwise, direction and to move the frictionwheel 18 out of contact with the friction-drum. Thus the friction-Wheel 17 becomes substantially the only medium through which power ing the inertia-wheel into motion, and, again,
the inertia-wheel may be set in motion by turning the running-wheels by hand or any other suitable means.
It may be noted that 1 preferably make the friction- wheel 17 and 18 and the drum 8 of wood, as it is light and inexpensive. I do not, however, desire to be limited to any particular material.
While I have described the preferred form of my invention, I do not desire to be limited to the exact details of construction shown, as changes in form and proportion will suggest themselves to those skilled in this particular art. The scope of my invention is, however, defined in the claims hereinafter presented.
Having thus described my invention, I claim as new and desire to secure by Letters Patent of the United States 1.
