4 Claims. (Cl. 46-129.)

The general object ofthe invention is. to provide a toy in the form of a dog or other four-footed animal. and having various parts including a skeleton and feet'xwhich cooperate to effect leaping movements approximating those, of a live animal, the said leaping movements ofv the toy being eflfected by the application of external force, as for instance by means of a cord'attached to the neck p rti n- A more specific object of the invention i's-to provide various features of structure and arrangement for attaining the, above-stated more general object.

- Other objects of the invention will be apparent from the. drawings and from the following description .and claims. a

In the. drawings I have shown in detail one embodiment of; the invention, but it will be understood that various changes may be made from the constructionshown, and that the drawings are not to be construed .as. defining or limiting the scope of the invention, the claims forming a part; of this specification being relied upon for that purpose.

. Of the drawings:

F g. 1 is a perspective view-of a leaping animal toy embodying the invention.

Fig. 2, is a perspective view. of the skeleton of the toy.

Big. 3 is an enlarged vertical sectional view of one of the feet.

Eig-s. 4 to9. are schematic views showing representative motions.

Referring to the drawings, represents generally the skeleton. of a leapinganimal toy embodying-the invention, the skeleton being preferably formed entirely-from metallic. parts. The skeleton includes a longitudinal spine 12,, twosimilar front legs 14 and 16 and two similar rear legs 18 and 20. .The upper ends of. the several legs are gidly secured to the spine 12. The two front legsare transversely spaced. and symmetrically located withere- .SQQQt to a, vertical longitudinal plane through the spine and the two rear legs are also transversely spaced and symmetrically located with respect to thesaid plane.

Front feet 22-. and 24. are secured to the bottoms of the front legs 14 and 16 and rear feet 26 and 28 are secured to the bottomsof the rear legs 18 and 20. The several parts of the, skeleton have predetermined relative positions of repose, as shown in Fig. 2, in which positions the bottoms of the four legs and the four feet are in, a predetermined relationship.

The spine 12 is .flexible. upwardly and downwardly and is resilient being preferably formed of a fiat spring; strip. The legs are relatively rigid throughout, being preferably formed of wire. The two front legs may be formed from a single piece of wire which is rigidly clamped to the front portion of the spine by means of a sheet metal member 30. The two rear legs may be formed from a single piece of wire which is rigidly clamped to the rear portion of the spine by means of a sheet metal member 32. The spine hasa forwardly extending neck portion 34 and prefstably includes a separate tail portion 36.

The skeleton as generally described above: may be provided witha suitable covering to simulate an-animal as shown in Fig. l. A dog is illustrated but it will be understood that the invention is not so limited. The covering for the skeleton includes a skin 35 formed from a suitable fabric and also includes suitable stufling to hold the skin in the required shape. The bottom of the leg portions of the skin are suitably connected with the several feet. It will be understood that the skin and the stufling are readily flexible to the extent necessary to permit free relative movements of the parts of the skeleton as hereinafter described. A head 40 is carried by theneck portion 34 of the spine and a tall 42 may be-carried by-the tail portion 36 of the spine.

Each of t e feet 2:, 24, 26 and 28 preferably includes an outer floor engaging covering or portion formed of a material serving to provide substantial frictional resistance to slidingmovement of the foot with respect to the floor. This covering is preferably rubber or an equivalent material. It will be understood that the term "rubber is herein used in a generic sense and is intended to include not only natural rubber but also various rubber substitutes. In order to insure firm engagement of the feet with the door and to thus enable the rubber portion to effectively resist sliding movement, the said feet together with the corresponding legs are relatively heavy.

Preferably each foot is provided with an individual weight.

As to the exact structure of the feet there maybe wide variation, but each of the feet may advantageously be formed as shown in Fig. 3. A relatively heavy weight 44, formed preferably of lead, is cast in place around the lower end portion of the leg and abody 46 of rubber is molded in place around the weig t and around the portion of the leg adjacent the weight. As shown the rubber body46 has a groove 48 for use in -connecting the skin 38-with the foot. The portion of the skin constituting the leg surrounds the upper portion of the foot and is pressed into the groove 48 by a wire ring 50.

Means is provided for connecting-a cord such as 52 with the front portion of the spine 12, preferably at the 'neck 34. As shown, a collar 54 surrounds thestuifed neck and the cord 52 is connected to the collar.

Secured to the neck portion 34 of the spine and within .the head is a counterweight 56. The counterweight 56 is of such mass and is so positioned that it approximately balances the rear portion of the toy, tending to cause it to pivot about the front feet 22- and 24.. In "fact, the mass and position of the counterweight may advantageously be such as to slightly overbalance the weight of the rear portion of the toy. i

The manner of operation'of the toy is illustrated generally in Figs. 4 to 9, but it will be understood that the action shown is intended to be representative and not necessarily actual. The toy moves approXimately in, the manner shown and to be described, and the reasons for the movement will be explained so far as now understood.

Fig. 4 shows the parts in their positions of repose.

The flexible and resilient spine. 12 hasan unfiened position, as shown by dotted lines, to which it. tendstomove, but by reason of the counterweight-56 the spine in the position of repose is flexed. upwardly from its, said unflexed, position. By reason of. he action of. the counter;- wei'ght the rear feet exert little .or no pressure against the floor. In fact when the counterweight overbalances the rear portion of the toy, it is necessary to maintain a slight tension in the cord 52 in order to prevent the toy from pivoting forwardly.

To start the movement of the toy, the cord 52 is pulled in a forward and upward direction as shown in Fig. 5, it being understood that the user moves forwardly as the are so lifted, the spine 12 returns to its before-mentioned unfiexed position, thus moving the front feetforwardly .as shown in Fig. 5. The action of the spine in moving the front feet forwardly is supplemented by the..;forward and upward tension in the cord. By, reason of momentum the front feet moveforwardlyto such an extent as shown in Fig. 6 that the spine isflexed downwardly, be-

:yond its before-mentioned,unflexedposition.

As soon as the front feet 22, .24 havevreached their .maximum forward positions,,as shown in'Fig. 6, the

tension in the cord 52 is released and the, front feet engage the floor, as shown in Fig. 7. The front feet firmly engage the floor and they remain momentarily in fixed position with respect thereto. The weight of the counterweight 56 together with its downwardmomentum, serves to lift the rear feet 26, 28 from the floor as shown. As

.soon as the rear feetleave the floor the spine flexes upwardly toward its unflexed position and .the rear , feet 26, 28 are moved forwardly, as shown in Fig. 8. The momentum of the forwardly moving rear feet causes them to move beyond a positioncorresponding to the unflexed position of the spine 12, the spine being then :flexed upwardly as shown in Fig. 9. As soon as the position shown=in Fig. 9 is reached, the tension is restoredin the cord 52 and the before-described sequence of movements is repeated, as shown in Figs. m9. It will be observed, however, that after the first cycle there is an increased force tending to move the front feet forwardly as shown in Figs. 5 and 6. This is due to the fact that the spine 12 is flexed upwardly to a greater extent in the Fig. 9 position than it is in the Fig. 4 position of repose.

The action as described is due at least in part to the relatively great stiffness of the legs 14, 16 and 18, 20 and to the relatively great vertical flexibility of the resilient spine 12, said spine although readily flexible vertically as stated having very large resistance to lateral flexing and very large resistance to twisting.

From the foregoing description it will be observed that the toy constituting the present embodiment of the invention is actuated by intermittently tensioning and releasing the cord 52. The front feet move substantially inunison and the rear feet move substantially in unison, and the action therefore resembles leaping rather than walking. The tensioning and releasing of the cord must be timed in synchronism with the leaping movements.

The invention claimed is:
