This invention relates to wheeled toys, and more especially to toys of the kind which are equipped with driving means either in the form of a fly-wheel or in the form of a spring @l or the like.

My present invention consists essentially therein that the center of gravity of the wheeled toy is located at such a low point of the body of the toy--which may be done .10; either by properly distributing the masses or by imparting a proper weight to the under parts of the toy-with the result that the wheeled toy, when placed or thrown on the ground or when normally traveling thereon will tumble over and again come into its in' toy which is driven by action of spring power.

In the drawing I have shown my present toy as being of the form of a mouse, it is, however, evident, that any other form of animal or human figure may be given to the toy.

Fig. 1 is a side-view of the toy partly in cross-section, and Fig. 2 a top-view of the base-plate or bottom of the toy comprising the wheels and the spring-power actuated driving works, and Fig. 8 a partial transverse section through the toy showing in particular the position of the center of gravity of the body of the toy permitting said toy to again come up its wheels after tumbling.

A principal feature of the construction o the toy shown in the drawing consists therein that the masses of the body of the toy are properly arranged or distributed to permit automatic erection of the toy after tumbling. Such stand-up or self-erecting figures as known are of a conformation having the under side of the iigure rounded to a smaller or greater extent, the center of gravity being at the same time positioned below the center of rotation and at such a distance from the latter that the figure will automatically erect itself no matter in which way it had been set or thrown on a surface,

such as the ground.

In my new wheeled toy, now more partic- 476,122, and in Germany October 26, 1829.

ularly, the center of gravity S is placed at such a polnt below the center of rotation of the toy and at such a distance from the latter that said center of gravity will be placed as much as possible in proximity to the under part of the toy, that is to the base-plate 1, or if necessary, still further below said baseplate, while the center of rotation of the toy is positioned above its center of gravity. v

A construction of this kind is represented in Fig. 3. It will be seen that a couple of forces Ss and Dd will tend to keep the toy in its normal position and to come to stand again upon its wheels or legs, as the case may be, after tumbling. This erection of the toy is due to the tendency of these forces to rotate the toy, Iirrespective of the fact whether the toy is thrown towards the side during its normal forward motion on the ground or whether it has been placed or thrown on the ground in oblique position prior to its normal travel on the ground. In order to displace the center of gravity of my present wheeled toy as much as possible to a point below the centervof rotation the entire operating mechanism of the toy, that is the driving means which consist of a spring, as Well as of the wheels of the toy are mounted upon the base-plate 1 which forms the bot- `tom of the hollow or cap-shaped body of the lmechanism, and serves as a support for the entire driving and running toy. The masses of the toy are so distributed that the center of gravity of the entire toy body is positioned at a point as low as possible.

The driving wheels 4 which project downwardly Jfrom the base-plate 1 are carried through slots 11 provided in the latter. A running wheel 12 is mounted at the rear part of the base-plate 1, said running wheel projecting from said base-plate through the slot 13 therein. The axle of the running Wheel 12 may be positioned obliquely to the axle of the rear or driving wheels 4, if it is de sired for instance, to have the toy travel along a circular line.

Evidently, the aforedescribed wheeled toy which is shown as having three wheels may also be equipped with any desired greater number of driving as well as running wheels.

I' A further-novel feature of the construction Izo of the runnin wheel 12 consists therein that it is provide with a nose or lug as shown in Fig. 1 which nose or lug will have the effect that the toy during travel will be periodically tossed upward to simulate the jumping motion of an animal. I am aware that itA A1s known to -impart a wave-shaped upward and downward motion to wheeled toys -by means of eccentric gears orl wheels formin part of the driving mechanism the so efecte motion, however, will be more or less unnatural in connection with wheeled toys and in addition to this will not give 'a yleasing impression toa ychild playing w1th the toy. Such a lug or nose 17 evidently may also be provided at the driving wheels.- By reason of the fact that the driving 'wheels consist of an elastic middle member in the form of a disk or ring mounted within lateral plates,

- the a'dhesion .to the running surface will be greatly increased. A wheeled toy constructed according to my invention will run very easily and practically noiseless over its running surface. Tlie base-plate 1 together with the driv? ing mechanism mounted thereon may be connectd in any suitable manner with the' hollowbody 2 of the toy, for instance, by providing tongues on said body 2, said tongues being inserted into proper slots in the baseplate 1 and then bent around the under surface thereof. 'As a matter of course, the connection between the base-plate 1 and the body 2 ofthe toy. may also be made in any desired other way. In case the body ofthe toy is given the form of a mouse as shown in the drawing, a tail preferably with a knot at lits front end is jammed in Abetween the body 2 and the base-plate 1 asshowyn in Fig. 1 when assembling the toy. The tail is preferably. made of a very elastic material, for instance, a rubber cord a rubber hose, a helically wound wire spring or the like. By this the effect is obtained that the toy when placed uponV a running surface after having the spring woundup and keeping the toy xed by gripping the rear end of the tail with the hand, the toy although'having the tendency of moving forward will be prevented against doing this,`with the effect that the toy will jump up and down on the running surface thus simulating most naturally the hopping or similar motion of av mouse. In case the toy travels at relatively high speed over its running surface, it may `frequently happen that it will hit against some obstacle which will cause it to tumble over to the side i or to even turn about to makea` full som'- ersault. Since according to my present invention the center of gravity of the toy is placed so low that the toy will have the properties of a self-erecting figure, the toy will always again come to stand upon its wheels and may now continue its forward straight or circular travel as the case may be.

`Lamme It is evident, that the cross-sectional Conformation of the body of the toy needs not necessarily to follow a circular line, it being only necessary that the under part fthe cross-section of the figure'is properly rounded towards the inside or of a conformation resemblin a circular line in order to safel effect sel -erection of the toy after tumb ing. The body of the toy, therefore, ma be of any desired cross-sectional form and a so of relatively large heighhf In order to bring about self-erection of the toyaftcr tumbling, the bod of the toy must be of such cross-sectional con ormation thatA during l.tumbling it will move in such a manner towardsthe side that it will come to lie upon the more or less circularly formed and inwardly directed sides of the body of the toy, whereupon the latter will erect itself and come to stand again upon its wheels which is due to the low center of gravity of the toy as above described.

The body 2 of the toy may be made of an desired material, for instance, sheet meta, pressed pasteboard, celluloid or also of sheetmetal bodies having a coating which may consist of cloth, felt, velvet or the like.

According to my invention furthermore, the driving works are equipped with an automatically acting lookin mechanism which serves for keeping the riving works in operation only during travel of the toy and loc ing said driving works as soon as the wheels ofv the toy come ont of contact with the ground.- This locking mechanism, therefore, will prevent'the driving mechanism from rotating. The locking mechanism on the other hand will be released and unlock the sping actuated driving mechanism', while the wheels of the toy are in contactwith the ground and in all other conditions of the toy, especially during motion of tumbling.

The bottom or baselate 1 is provided with a downwardly curve portion 10 lled up with a heavy mass 10 or in some other way properly weighted for the purpose of placing the centerof gravity of the figure of the toy as near as possible to the running surface. Mounted upon the base-plate 1 is a frame 5 which serves for the reception of a s ring actuated driving mechanism, the axle or winding up said driving mechanism being shown at 8. This winding-up axle is-connected to one end of a spiral spring 22 and carries in known manner a driving gear 7 which by the aid of a train of intermediary gears acts upon a small gear or pinion 6 fixedly mounted upon the axle 3 carrying the driving wheelsv 4,-.said latter axle being mounted likewise within said frame 5; The driving wheels 4 project at their under periphery through slots 11 in the base-plate l. The base-plate l is further provided at its front end with a supporting or running wheel 12 preferably provided with a nose or lug. The frame 5 is further equipped. at its front end with two Laveno@ oppositely positioned bearings 24 in which an adjusting lever 25 is mounted swingably in upward and downward direction. The lever 25 is under the action of the pressure spring 23 having the tendency to move the lever in downward direction. The lever 25 projects with its rear free end 26 between the driving wheels 4 in downward direction and passes through an a erture in the base-plate 1 so that it will polnt towards the running surface or ground upon which the toy travels.

The lever 25 is further provided with a lateral arm 27 forming the locking member proper which engages either with the driving works or which acts as shown in the construction according to Figs. 1 and 2, in the manner of a brake against the periphery of one "of the driving wheels whenever these are out of contact with the ground and whenever the lever 25 is pressed towards the outside that is towards below by action of the pressure spring 23. From this it follows that the lateral arm or locking member proper 27 will be lifted out of engagement with the driving 25 mechanism permitting' proper operation of the latter` Whenever the toy rests upon the driving wheels., On the other hand, the arm or locking member 27 `will lock the driving mechanism in every other position of the toy 30 especially during tumbling towards the side.

It is noted that the 'locking mechanism forming part of my present invention will act fully automatically in both ways, viz: when locking the driving mechanism as well as when releasing it to bring it into operative connection with the driving wheels.

The base-plate 1 together with the frame 5 and the spring actuated driving and locking mechanism is covered up by the hollow body 40 2 of the figure of the toy. An aperture on the side of the base-plate 1 permits insertion of a key permitting to wind-up the driving works. A
