MECHANISM FOR AUTOMATICALLY CAUSING CHANGE IN DIRECTION OF COURSEOF TRAVEL OF TOYS Filed April 27, 1956 2 Sheets-Sheet 2 I INVENTOR. C F flowrsolv.

ATTORNEY j to the annexed drawings for a more complete Patented Get. 13, 1936 UNITED STATES PATENT OFFICE MECHANISM FOR AUTOMATICALLY CAUS- ING CHANGE IN DIRECTION OF COURSE OF TRAVEL OF TOYS The present invention relates to toys and more particularly to mechanism for causing changes in "the direction of travel thereof without the intervention of any human agency.

Among the-objects of this invention are to produce a novel effect in the operation of a self-propulsive toy; to provide a toy which will, at a certain point of its operation, discontinue travelling in one direction and start off in another direction; to provide a toy of the nature indicated which is automatic in its operation; and such further objects, advantages, and capabilities as will hereafter appear and as are inherent in the construction disclosed herein. My invention further resides in the combination, construction, and arrangement of parts illustrated in the accompanying drawings and, while I have shown therein what is now considered the preferred embodiment of this invention, I desire the same to be understood as illustrative only and not tobe interpreted in a limiting sense. r

In the drawings annexed hereto and forming a part hereof,

Fig. 1 represents a plan view of a toy motor vehicle showing the general location of the operating mechanism vof the vehicle;

Fl 2 represents a side view further illustrating the location of this operating mechanism;

Fig. -3 represents a fragmentary horizontal section of the rear portion of the toy vehicle,

showing more in detail the operating mechanism therefor;

Fig- 4 represents a vertical, longitudinal section taken approximately along the plane indicated by the broken line 4-4, Fig. 3;

Fig. 5 represents a vertical, transverse section taken approximately along the plane of the axis of the winding shaft; and

Fig. 6 represents a vertical section taken through the cam mechanism approximately along the plane indicated by --the line 6-6, Fig". .5.

Reference will now be made in greater-detail disclosure of this invention. The motor vehicle body, as a whole,-is designated by the numeral I.

. This has a cross member 2 extending across the 5)v middle portion thereof and to this cross member is connected a frame 3, this frame being connected also to the rear portion of the vehicle body. This frame serves to support the rear end of the vehicle upon the axle 4. Upon the end of this axle and connected thereto in driving rela- 20 of the plate I3 will engage the holes 2| of the tion are the wheels 5 which serve to propel the vehicle as the motive means thereof runs down. This motive means comprises the spring 6 mounted on the winding shaft 1 which is mounted on the frame 3 and the angle-shaped 5 support 8. This support 8 has a part 9 extending horizontally underneath the spring to prevent the same from sagging when it unwinds.

One end of the spring 6 is secured to the cross member 2, as shown most clearly in Figs. 3 and 4. 10 A disc 10 is mounted on the shaft 1 between the angle-shaped member 8 and the spring 6 and serves as an abutment for one side of the spring to hold the same in place. Upon the opposite side of the spring is a distorted spring plate II which presses against the spring and against the disc l2 which is provided around its periphery with gear teeth. The opening throughthe center of the gear I2 is large enough so that the part of the shaft 1 which passes therethrough and which is square in cross section may turn freely with relation to the gear. A disc l3 having a square opening therein to fit the shaft 1 is provided with spring fingers to engage the openings in the gear I2 so as to connect the two in driving rela-. tion and serve as a ratchet when the spring motor is being wound up. The teeth of the gear l2 mesh with the teeth of the gear l4 on the shaft I5, mounted in the frame 3 and the angle member B. A gear I6, also mounted on the shaft l5 and rigidly connected therewith, has driving engagement with a corresponding gear on the axle 4, thus serving to transmit power from the spring 6 through the shaft 1, plate I3, gears l2, l4, l6, and the gear on the axle 4, whereby to drive the vehicle forwardly.

A hearing member I! is pinned to the shaft I and extends through an opening in the frame 3, which opening is provided with a flange l8. A

spring I 9 surrounds the small inner end of the bushing l1 and bears at one end against a shoulder of this bushing and at its opposite end against the plate it. Therefore, the gear l2 and plate l3 are held resiliently between the two springs II and I9, thus insuring that the fingers gear l2 and maintain the two in driving relation A support 22 is mounted on the axle 4 in a manner so that it may oscillate about this .axle during operation of thetoy. A shaft 23 is mounted in the support 22 for rotation therein and carries at its rear end a wheel 24 which is intermittently brought down to engage the support upon which the toy is running. A hole 25 is formed in the support 22and the metal thereof is bent downwardly to form a bracket 26 through which the shaft 23 passes and in which it rotates. Upon the inner end of the shaft 23 is mounted a bevel gear 21 which meshes with a corresponding gear 28 upon the axle 4. It will thus be seen that when the axle is driven it will cause driving of the

gears

21 and 28 and the shaft 23 which causes rotation of the wheel 24. In order to hold the support 22 up so as to hold the wheel out of engagement with the surface which it intermittently engages, a coiled spring 29 surroundsthe axle 4 and has one end engaged with the frame 3, as shown at 30. The other end 3| of the spring extends into an opening in the side of the support 22 and, therefore, when the spring is under tension, its tendency is to raise the wheel 24.

A lever 32 is pivoted at 33 upon the support 22 and may be swung sidewise more or less, being shown in its extreme positions in Fig. 3 by the solid and the dotted lines. This lever 32 is provided with a finger 34 engageable by actuating

members

35 and 36 which are provided -with square holes to engage the shaft 1. These are illustrated as being held in place on the shaft by means of a pin 3! passing therethrough, although they may fit the shaft tightly enough so that this pin is unnecessary. The lever 32 is provided with a finger piece 38 by means of which it may, be swung laterally so that the finger 34 will be engaged by the arm or arms of one or theother of the actuating

members

35 and 36 or else be out of position to be engaged by either of them, as indicated by the dotted lines in Fig. 3. The actuating member or members .35, 36 may be made unitary or independent, asdesired.

When the key-handle 40, forming a partof shaft 1, is turned in the proper direction, it winds up the spring 6 and then the toy may be' placed upon the floor or some other support and permitted to run. It then runsstraight'ahead for a distance which is dependent upon the position of the actuating

member

35 or 36 and the position of the lever 32. We will assume that the parts are in the positions shown in Figs. 3 and 4. The toy will then run straight ahead for a short distance until the arm 36 raises the finger 34 tocause the wheel 24 to contact the floor, thereby causing the raising of the rear end of the vehicle. Now,-since the wheel 24 is rotating transversely of the vehicle, it will cause the rear end thereof to swing around until the arm 36 releases the finger 34 so that the spring 29 may cause the wheel 24 to be lifted out of contact with the floor. When this happens, the wheels 5 again contact the floor and drive the vehicle straight ahead. On account of the small size of the arms of the actuating member 36, the wheel 24 is held down only long enough to cause the vehicle to turn through ninety degrees and, therefore, when lever 32 is swung over so that finger 34 is engaged by the actuating member 36 the vehicle will run in substantially a square. Onv the other hand, when the lever 32 is set in the position shown in Fig. 3, the vehicle will turn through one hundred eighty degrees and run back and forth prectically on a straight line.

It is obvious from the foregoing that when the spring motor is wound up and the vehicle placed onthe floor, the unwinding of the spring will cause turning of the axle 4 and the wheel 5. Since the gear 28 is mounted on the axle 4, this will also be caused to turn and, in turn, will cause turning of the gear 25 and wheel 24. Therefore, the wheel 241s always turning when the vehicle is advancing. The vehicle will be caused to change its direction of travel only when one of the actuating

members

35 and 36 causes the wheel 24 to lift the rear end of the vehicle.

It is within the scope of this invention to build this toy with a single supporting wheel at one end and one or more wheels 24 to cause change in direction of travel of the toy.

It will of course be understood that the spe'cifi description of structure set forth above may be departed from without departing from the spirit of this invention as set forth in this specification and the appended claims.
