TOY VEHICLE.

Application filed, May 21,

T0 all whom. t may concern.'

Be it known that I, EDWARD S. SAVAGE, a citizen of the United States, and resident of Rochester, in the county of Monroe and State of New York, have invented certain new and useful Improvements in Toy Vehicles, of which the following is a specification.

The present invention relates to toy vehicles and an object thereof is to provide a toy vehicle which may be propelled from a cable or other flexible connection extending from therear of the vehicle. Another object of the invention is to provide aI toy vehicle which may be propelledr and steered through a common device. A still further objectof the invention is tov provide a toy vehicle which may be propelled by successive pulls on a flexible connection extending from the rear thereof and may be steered by a lateral shifting of said connection while in a taut condition.

To these and other endsthe invention consists of certain parts and combinations` of parts, all of which will be hereinafter described, the novel features being pointed out in the appended claims.

In the drawings:

Fig. lis a. plan view of-a vehicle constructed in accordance with this invention;

Fig. 2 is a side view of said vehicle:

Fig. 3 is a vertical section through another embodiment of the invention;

Fig. 4 is a vertical longitudinal section through the embodiment shown in Fig. 3;

Fig. 5 is a horizontal section through the embodiment shown in Figs. `1 and 2;

Fig. 6 is a vertical section through such embodiment, and

Fig. V7 is a rear view of the vehicle illustrated in Fig. 2.

Referring more particularly to the drawings, 1 indicates the body ofthe vehicle which may beof any form and supported upon wheels, two of which are in this instance, in the form of two rear or driving wheels 2 and two in the forni of steering or forward wheels 3, the driving wheels being mounted upon an axle `4gwhile the steering vwheels are mounted upon spindles 5 pivo'ted at 6 to brackets 7 'and each having an arm 8 extending rearwardly therefrom, these arms being connected by a steering rod 9. The steering of the vehicle is secured by providing a steering lever or member 10 'pivoted at 11 to the body in front of the 1921. serial No. 471,402.

steering rod 9 and extending rearwardly from the body, being guided at 12 in a guideway formed on the under side of the casing 13 which is supported on the under side of the body and encloses the propelling mechanism, the steering member or lever 1() being extended rearwardly and upwardly from the body.

The propelling means of the embodiment shown in Figs. 1 and 2 is shown in Figs. 5 and 6 and comprises a spring motor in ai volute spring 14 secured at one end to the axle or drive shaft 4 enclosed within a .housing 15 to which the other end of the spring is secured. This housing turns on the shaft and has: one side closed by a gear 16 with which a. spring detent 17 cooperates.

For storing energy in this spring motor c there is provided a. Vdrum 18 which is mounted to turn upon a shaft 19 and has within itV a volute spring 20, one end of which is secured to the shaft 19, while the other end is secured to the drum. Also turning on the shaft 19 is a pinion 21 spaced from the side of the frame 13 by a sleeve 22 on the shaft, the pinion 21 mesh-A the pulling` of the cable tending to store up energy in the spring 2() dueto the rotation of the drum 18 on the shaft 19. This pulling of the cable 25 transmits motion from the drum to lthe gear 21 through the p-awls 24 and ratchet 23, the motion of the gear 21 being communicated to the gear 16 to store up energyin the spring 14 so as to drive th .shaft 4 from said spring. f f

In order that the spring 14 may be controlled, a governor'may be provided preferably in the formjof a flywheel 26 on a vshaft 27 which also has a pinion 28 meshing with a gear 29 turning loosely on the shaft 19 and connected rigidly to a pinion 30 which in turn meshes with a gear 31 rigidly secured to the shaft or axle 4. The

V`turning on the body la.

cable or flexible connection Q5 extends rearwardly from the vehicle preferably through an opening' 32 in the body and this cable preferably also leads through an opening in the steering member l0, a. ball 33 being provided on the cable or flexible connection for limiting the winding of the cable on the drum.

In the operation of y this embodiment of the invention, the user of the toy stands in the rear of the latter and gives successive pulls on the cable This stores up energy in the motor spring 14 which is transmitted to the wheels 2 to propel the vehicle. As the cable i5 connects with the steering member 1G, the vehicle may also be steered through the propelling cable, this being effected by holding the cable taut and pulling such cable laterally in the direction in which it is desired that the vehicle should turn.

` In the embodiment shown in Figs. 3 and 4, the steering mechanism is identical with that shown in Figs. l and 2,the difference being in the propelling mechanism ofl the vehicle. Instead of employing a spring motor, a momentum motor is employed. In` this embodiment the wheels 2a turn loosely on the shaft 4a which is supported against A cable a passes about a drum 34 which is mounted on a hollow shaft 35, the latter being journalled in a U shaped bracket 36 depending from the under side of the body la. Extending through this hollow shaft is a drive shaft 3'2" which is journalled in brackets 38 depending from the body la and has beyond said brackets friction drive wheels 39 which frictionally engage the peripheries of the rear wheels 2a in the manner shown in Fig. 3. The cable 25a leads about the drum 34'and lconnects with a winding drum 40 which is mounted to turn on the shaft 4a and encloses a volute spring 41, one end of which is securedto the shaft 4fl while the other endis secured to the drum 40. It is apparent that pulling upon the cable 25 will rotate the drum 34 and turn the drum 40 to tension the spring 41. Vhen the cable 25a is released the spring 41 will re-wind the cable on the drum 40. Driving connection between the hollow shaft 35 and the drive shaft 37 is established, through the provision of centrifugally operated pawls 42 pivoted at 43 to the hollow shaft 35 and adapted to cooperate with internal teeth 44 formed on a Hy wheel 45 whichis mounted upon the shaft 37. A second fly Wheel 46 is also mounted on said shaft in symmetrical relation with the fly wheel 45 to the drum It is apparent that, when the drum 34 is turned upon successive pulls of the cable 25a, the rotation of the drum 34 will, through lthe pawl and ratchet device, be communicated to the drive shaft 37, thus causing the turning of the ground wheels 2a. The fly wheels 45 and 4G provide ya momentum motor in which energy is stored through the cable for the purpose of Ikeeping the vehicle in continuous motion.

From the foregoing it will be seen that there has been provided a toy vehicle which is propelled from the rear through a flexible connection. This flexible connection leads about a spring drum and after each successive pull there-on, is re-wound on the drum. Through the flexible connection, motion is transmitted to the wheels of the vehicle preferably through a propelling mechanism which maintains substantially continuous motion in the vehicle during the time when the flexible connection is being wound on the drum. There is also provided a vehicle which is propelled and steered through acommon member preferably in the form of a flexible connection leading from therearr of the vehicle.

that I claim as my invention and desire to secure by Letters Patent is :r

l7 A wheeled toy vehicle comprising a steering mechanism, a propelling mechanism, and a cable connected with the propeiling mechanism for effecting the propelling of the vehicle through a longitudinal movement of the cable and connected with the steering mechanism between its ends to cause thelatter to shift when the cable is moved laterally from a point be.- yond the connection with the steering mechat msm. i
