CHILDS vnnrom.

Application filed November 11, 1926. SerialNo. 147,749. 1

This invention relates to a childs vehicle. It is theprincipal object of the present invention to provide a childs vehicle having the general design of an aeroplane, and which vehicle may be easily propelled and steered and when in motion will appear similar to an aeroplane in flight. The present invention contemplates the use of a body member carrying a seat, the forward end of said member being fitted with imitation aeroplane wings, the rear of said member being fit tedwith an imitation rudder and ailerons A propeller is mounted upon the front of vthe vehiclevand running gear is provided for the'support of a vehicle and by which running gear the propeller may be driven.

The invention is illustrated by way of example in the accompanying drawings, of which 7 Figure 1 is a plan view of the childs vehicle with which the present invention is concerned.

Referring more particularly to the draw-V ings; 10 indicates the fuselage of a toy aeroplane which forms the body of the vehicle with which the present invention is concerned. This fuselage is made in two partsa main body portion 11 and a forward portion 12 articulately connected thereto. The connection is particularly shown in Figures 6 and 8,1 where it will be seen that the member 11 has a, curved forbers of the landing gear.

ward portion as indicated at 12-13, which fits in an arcuate recess 14 of similar contour. The members are pivoted one with relation to the other, upon a vertically disposed bolt 15 which passes through T-

shaped plates

16 and 17 disposed above and below the body member 11. The head portions of these Ts are securely bolted to the forward body member 12 and thus insures that the forward body member will swing around the pivot pin 15.

The forward body member 12 is fitted with a pair of

imitation aeroplane wings

18 and 19 secured above and below the body member as clearly indicated in Figures 2 and 3; These members are rigidly held in spaced relation to each other by

vertical posts

20 and 21 which are secured between the members. Contiguous of these, posts indicated at 22 and 231 in Figure 3 extend downwardly from beneath the lower wing 19 and form theforks or supporting mem- These forks are rigidly reinforced by hearing straps 24 which extend downwardly along the inner sides of the post and are bent around the lower ends thereof and extend upwardly along the outer faces of

theposts

22 and 23. Openings are provided in the straps and through the posts to "receive the axles 25 of running gear wheels 26. A pair of these wheels is therefore disposed as a part of thefront section of the structure and in a manner to make the vehicle dirigible. A central steering post 27 extends upwardly through the top wing 18 andis fitted with

steering grips

28 and 29 by which grips the entire front unit comprising the body section 12, the

wings

18 and 19 and the front wheels 26 may be turned with relation to the pivot bolt 15. and the body section 11. The forwardly projecting end of the body section 12 is fitted with a propeller 30 which 7 has a shaft 31 more clearly shown in Figure 6. The shaft 31 is rotatably mounted in the body portion 12 and terminates within a recess 32 where it is fitted with a pulley 33. 'A belt 34 extendsaround this pulley extends outwardly and carries a friction wheel 381st its outer end. The periphery of this wheel rests against the circumfer- V 56. The forward ends of the control rods" ence of one of the front wheels 26. The shaft 37 extends through slotted bearing members 39 and the shaft is yieldably held in its lowermost position by a suitable spring 10 which forces the shaft dowmvardly and thus forces the friction wheel 38 against the periphery of one of the wheels 26. In this manner the running gear wheel 26 and the friction wheel 38 are held in contact so that the friction wheel is driven. In this manner rotary motion will be imparted to the propeller to cause it to be rotated as the vehicle moves. The rearwardly extending body portion 11 of the vehicle is fitted with a seat 11. This seat may be of any desired design and is mounted upon a supporting post The posteXtends downwardly through a slotted open ing 13 in the body member 11 and may be adjustably supported by a pin 4+1 extending through openings in the post, and through an opening 16 in the body member 11. The rear end of the body member 11 terminates in an aileron wing 17.

At a point near the aileron wing a vertical shaft 18 is provided and is rotatably mounted through the body member 11. Suitable wheels 19 are rotatably secured to the lower end of the shaft e18 and may be swung during the steering operation in a manner which will be hereinafter set forth. The upper end of the shaft 48 carries a rudder structure 50 which will swing at the same time the wheels 19 are turned. The turning of the shaft 18 is brought about at the same time the forward section 12 of the body is swung on pivot 15. This is accomplished by a device hereshown as

con'iprising control rods

51 and 52. These rods are formed in two overlapping sections, theoverlapping ends being formed as particularly shown in Figure 5. Here it will be seen that the forward sections 58 are formed with astop portion 54 and then continue to form a loop 55 through which the rear sections 56 ex tend. The rear sections 56 extend through the loops 55 and lie parallel along the sections 53 and terminate at their forward ends in loops 57, passing around. the forward sections 53. An examination of Figure 7 of the drawings will show that when pull being exerted on one of the control rods, as for example 51. the stop member 54; will be pulled forwardly to the position indicated by dotted lines in Figure 5 and solid lines in Figure 7. This will cause the stop to engage loop 57 and produce atension on the entire control rod 51. At the same time the

sections

53 and 56 of the opposite control rod 52 will slide relative to each other as they tend to shorten and will cause the slack to be taken up by relative longitudinal movement between the

rod sections

53 and 51 and 52 are pivotally connected to a plate 57 and are connected at points on opposite sides of the longitudinal center of the body member 12-, and upon which center line the pivot bolt 15 is mounted. The rear ends of the rods are crossed and are connected to a plate and upon opposite sides of the axis of shaft 48, so that the swinging movement of the plate 57 in one direction will cause opposite swinging movement of the spindle shaft 18 and will cause the wheels 19 at the rear of the vehicle to turn'at an angle relative to the longitudinal axis of the body opposite from the angle assumed by the front wheels 26, at the same time'thus shortening the turning radius of the vehicle.

In operation of the present invention, the occupant of the vehicle sits upon the seat ll and astride the body member 11. The vehicle is propelled wh-en the operator shoves on the ground with his feet to force the vehicle forwardly. The vehicle may be steered by turning the handle grips 28 and 29 which will also turn the forward portion 12 of the body and the running gear structure con'lprising wheels 26. At the same time, the

control rods

51 and 52 will act to turn the rear wheels in an opposite direction from the turning angle of the front wheels and will permit the vehicle to be turned in a con'iparatively small space. As the vehicle advances, frictional engagement of one of the front wheels 26and the friction wheel 38 will cause the propeller wheel to be driven. V

While I have shown the preferred form of my invention, as now known to me, it will be understood that various changes might be made in the combination. construction and arrangement of parts without departing from the spirit of the invention as claimed.

Having thus described my invention what I claimand desire to secure. by Letters Patent isp 1.
