TOY.

Application filed January 7, 1921.

T 0 all 101mm it may concern.

Be it known that I, EDWARD F. JIfnRGENs, a citizen of the United States, residing at- Middletown, in the county of Butler and the State of Ohio. have invented certain new and useful Improvements in Toys, of which a specification.

The present invention relates to an automatically moving toy which walks or hops down an incline and consists of the combination and arrangement of parts hereinafter described and particularly set forth in the accompanying claims.

The invention has for its purpose to pro vide a simple, inexpensive and amusing toy of attractive appearance which operates automatically if placed on an incline and consisting of so few and such durable parts that there is little to become disarranged. A further object is to do away with springs, rubber bands or intricate mechanism eliminating the necessity of frequent repairs. It is made of wood or other suitable material.

The invention and its method of operation is illustrated in the accompanying drawing wherein:

Figures 1, 2, and 3 are side views of the toy in its different positions and Figure 4 is a front view.

Referring to the construction and opera tion and wherein like reference characters indicate corresponding parts in the views shown, 1 designates the body which represents an animal or other creature supported on a pair of legs 2.

The legs are rigidly fastened together by a metal bar 3 through the heels and a shaft 4 at the axis on which the legs are to swing. The shaft 4 turns freely in a hole through the body at rig t angles to its sides and located on a vertical center line a short distance above its center of gravity (0. g.)

To operate, the toy must be placed on an inclined plane. The cycle through which it passes is best understood by referring to the drawing.

Figure 1 shows the toy in its central position, in the act of rolling down the incline as if upon a pair of wheels. To that end the soles of the feet are circular in shape the diameter of said circle' being equal to the distance from the center of the shaft 4 to the sole of the foot and really represent a segment of a circle or of a{ wheel.

The body is supported on the shaft 4 and Specification of Letters Patent.

Patented July 4, 1922. Serial No. 435,689.

the center of. gravity being under the bar the body assumes a horizontal position except as affected by subsequent events.

lVhen the toy has rolled along so that the supporting point or point of contact with the inclined plane is approaching the toes as in Figure 3 the bar 3 strikes the bottom of the body which is provided with a stop 5 which is so located as to act in-conjunction with the bar 3 to arrest the swing of the legs at the proper time.

Body and legs now being held rigidly together by the force of gravity the entire combination revolves about the point 6, Figure 2 located at the toes. The point of'contact 6, Figure 2 being located to the right of a vertical line through the center of gravity the forward portion is the heavier and is pulled down by the force of gravity with sufficient force so that when the body strikes the incline on the specially shaped and located breast '7 it has gained suiiicient m0- mentum to cause it to roll on the curved surface 7 until its action is arrested by the specially located nose '8. The body is provided with a high back 10 so as to insure the necessary momentum or rolling motion on the breast. It will be seen that in this position the feet are lifted clear of the incline due to the fact that the breast 7 is so prominent as to have a greater distance from point 7 to the shaft 4 than the distance from the soles of the feet to the shaft 4.

The feet being clear of the incline and of sufficiently heavy material swing forward pendulum like until the bar 3 strikes the stop 9. This stops the swing of the legs when they are in the proper position for beginning the next event. This position is illustrated by Figure 3.

The center of gravity now being located to the right of the supporting point the rear end descends until the hump 11 on the tail strikes the incline. The tail is properly shaped to act as a balance for the head and forward part of the body and so located as to strike the incline just after the heels are carried down and again bear on the incline. The momentum gained during the downward travel of the tail now causes the tail in conjunction with the pivot at at. to lift the breast clear of the incline and rolling on the feet the toy proceeds down the incline completing the cycle.

The toy can be made to take long strides therefore I do not wish to be limited to such leg device-pivoted to said body at a point adjacent the center of gravity of said body and having a curved foot surface outside the contour of the body, a fulcrum surface on the body adapted to alternate with the 7 device in. supporting the body, said device adapted to swing forwardly to a point where a portion of the curved foot surface is in advance of said fulcrum and means to limit the extent of the swinging movement of said device.
