Description

Feb E59 i949. A. ADAMQZYK MOTOR PROPELLED TOY VEHICLE Filed Dec. 11, 194e Patented Feb. 155,` 1949 sna'haft"extending transversely to the axis of the Wheels are known. However, such a wheel is incapable of lifting the front part of the vehicle above the level of the travel surface, nor cause the toy to turn when traveling on. an even surface or reaching a wall.

With these and other objects in view that will be apparent from the detailed description of my invention, the latter consists in the novel construction, combination and arrangement of parts as will be hereinafter specified and defined in the appended claims. y

In the accompanying drawing which constitutes part of this specification and in which similar reference characters denote corresponding parts:

Fig. 1 is a side elevation of my toy vehicle,

Fig. 2 is a top plan view thereof,

Fig 3 is a side elevation of a modified construction,

Fig. 4 is a cross section on line 4-4 of Fig. 2, and

I denotes the chassis of the toy vehicle pro vided with front wheels II, I2, mounted on a shaft I3 and rear Wheels I4, Wheel, say I4, is idle, being fixed on a sleeve rotatively mounted on the motor driven shaft I6 and the other wheel I5 is xed to said shaft. Extending longitudinally of the chassis and at a right angle to the shafts I3, I 6, is a shaft I1, slideably and rotatively mounted in bearings I 8. I9 denotes a wheel, disc or like member, which is shaped as shown in Fig. 4, and fixed on shaft I1 and projects downwardly through a recess provide I *f #2,451,642, A

I5, of Iwhich one lowered, as shown in Fig. l, as a result of which the member I9 comes to bear on said travel sur face. Due to friction exerted between said mem-A ber and said surface, movement of the vehicle in the same direction will cease, while due to inertia and against the tension of its spring I8a said member will be pushed rearwardly, causing the gear 2| to engage the motor driven gear 22 and at the same time the gear 23 to engage the gear 24 of the idle wheel I4. This has the effect that the member I9 will be set into rotation and due to its shape or its eccentric mounting, will lift the front part of the vehicle above the level of the travel surface T, and at the same time change the course-of the vehicle. This change of direction of travel is facilitated by the rotation of the idle Wheel I4 in the direction opposite to that of the driven wheel I5, which rotation is imparted to it by the engagement of gear 23 with f gear 24.

In the modification shown in Fig. 3, means are provided whereby the vehicle automatically may be caused to change its direction of travel intermittently.`

In the present example, these means comprise a rotary Wheel, disc or member 26 which is suitably impelled by the motor. This member 26 has pivoted to it eccentrically as at 21a a rod 21 extending forwardly and longitudinally of the chassis. The front end of said rod 21 is provided with suitable means, such as a hook shaped part 21h capable of engaging the member I9, so that, during the rotation of the member 26, said rod will reciprocate and intermittently pull the lively supported on said frame member I9 rearwardly, as a result of which the vehicle will be caused to change its direction of travel, as already explained.

In the constructions heretofore described, wheel I9 is provided with means by which it will be moved rearwardly so that its shaft l1-wil1 be coupled to the motor 22a' Such coupling, how,- ever, may be dispensed with. In such case, the locking action of wheel i9 will cause the driven rear wheel to swing the toy around the idle wheel, and after the wheel i9 has made one turn and the front part of the toy is turned back to the travel surface, spring I8a will bring Wheel I9 in contact with the locking stop I8@l thus permitting the toy to travel in the new direction.

' travel.

Each change of the course of `travel may be signalled either visually or by sound. To this end, I provide a suitable device 28, using an electric bulb 30, bell or the like. The electricY circuit actuating said device` may be controlled by a switch 29 to be operated by the forward end Ha of the shaft Il, so that every time the shaft il is moved rearwardly it will'close or open the electric circuit. v

While I have described my toy in connection with a vehicle, it is obvious that the construction may be modied in various ways without departing from the principle of my invention, so as to be also applicable to vfigures simulating humansV or animals. I, therefore, do not wish to restrict myself to any details of construction described and shown herein.

What I claim is:

1. In a self propelled toy, having a motor and frame with a pair of rear and front Wheels in which at least one of the rear wheels is motor driven and the other rear wheel idle, a spring inuenced eccentric member slideably and rotatintermediate its ends, and adapted normally tobe out of contact withthe travel surface, but to contact the latter 2. A motor propelled toy, according to claim 1, in v,which motor driven v'"reciprocatory means are provided which are adapted to intermittently pull said eccentric member rearwardly into operating connection with the motor so as to cause the vehicle to intermittently change its course.

3. A motor propelled toy, according to claim 1, in which are provided a motor rotated element, a

l rod eccentrically pivoted at one end to said element and extending forwardly from said element,

and means on the opposite end thereof capable of engaging said eccentric member and, when reciprcated by the rotation of said' element, to intermittently pull said member rearwardly into operative engagementl with said motor4 and thereby automatically cause the toy to intermittently change its course of travel.
