H. F. COGGON TOY VEHICLE Original Filed Ma 10. 1928 Fig.5.

W, ATTORNEY Patent ed Feb. 3, 1931 HARRY FROW COGGON', OIRHAIQIFAX, ENGLAND TOY vnmcnn Original application filed May 10, 1928, Serial N'o. 276,735, and in Great Britain Kay 19, 1927. Divided and this application filed March 21, 1929. Serial No. 848,958.

The present invention relates to toy ,vehicles and'more particularly to the means for steering toy vehicles when in motion.

The device according to the present invention is applicable to the apparatus for playing games as described in my patent application Ser. N 0. 276,735, filed May 10, 1928, and with the steering mechanism as described in the present application, the turn tables described in the device according to patent application Ser. No. 276,735, filed May 10, 1928, can be eliminated. I

' Acccording to the present invention each front wheel of a toy vehicle is mounted on the end of one arm of a multiple armed lever pivoted at the junction of said arms about a vertical shaft, the said levers being angularly displaceable about their shafts, in or er to steer the vehicle, .by the operation of a remote control actuating the movable core of a sheathed cable, the sheath of which is connected to the vehicle frame and the core of which is directly, or through the intermediary of link mechanism, connected to the levers.

struction of the device, Figure 1 showing the wheels angularly displaced to cause travel in one direction, and Figure 2 showing a simi-' lar construction with the wheels angularly displaced in the opposite direction.

Figure 3 is a view showing a modified form of construction of the remote control for displacement of the wheels of the vehicle. I i In Figures 1 and 2 the front wheels 46 of the vehicle carried onstub axles are mounted on vertical shafts 47 of the frame F by means of bell crank levers 67 which are interconnected by a link 48. A pin 49 on the link 48 engages in a slot 50 on one arm 51 of a three armed lever pivoted at 52; to a fixed part of the frame work of the vehicle, whilst to one of the remaining arms 51a of the three armed lever is attached a spring 53 whose other end is anchored to a fixed the framework of the vehicle.

art v53a of he remaining arm 51?) of the three armed lever is con nected b means of a flexible cable or lead 54 placeable, the outer sheath 546 being fixed to the plate 540 of the vehicle frame F.

The operation of the control is as follows 1 In order to cause the model to be propelled in a straight line without any change of direction the finger control 55 is depressed to half its full extent which causes the wheels to take up a position shown in dotted lines in Figure 2. When however, change of direction of the toy vehicle is desired, the finger control is either released, whereupon the spring 53 causes the wheels to take up the position shown in full lines in Figure 2 which causes the vehicle to turn in one direction, or alternatively the finger control 55 is completely depressed which causes the wheels to take up the position on the opposite side of the dotted line position which ensures the vehicle turning in the opposite direction.

A suitable stop 66 on the frame F is provided tolimit the extreme movements of angularity of the wheels.

Figure 3 illustrates a modified form of remote control to take the place of the remote control 54a, 55 of Figure 2 if desired.

The core 54 of the flexible cable is connected to the lever 63 at whilst the sheath of the flexible cable is secured to a rigid sleeve 62 mounted on the lever 64 at 60a. The operation of the control is as followsthe two levers at their connecting ends 60 and 60a for the cable are caused to be opened out by the pressure of the hand of the person on the levers 63 and 64 at their free-end whereupon the core of'the flexible connection is displaced in respect to its sheath, resulting in the member 56 carrying the front or steering wheels being suitably swung about its pivot 57 to suit the desired direction of travel.

I declare that what I claim is 1. A toy vehicle consisting of a frame, bell crank levers mounted on vertical pivots on said frame and provided at one end of each with an axle, wheels mounted on said axles, a link connecting to ther the other ends of a T-shaped ever pivotally mounted on the frame of the vehicle, a connection between one arm of said T-shaped lever and said 7 link, a Bowden wire remote control for angularly displacing said T-sha d lever and connected to one end of said ever to move the latter in one direction, and spring means connected between said T-sha d lever and the frame to move the said -shaped lever in the other direction.

2. A toy vehicle comprising a frame, a pair of hell crank levers mounted on vertical pivots on said frame andeach carrying a front v wheel at one end, a link for connecting the other ends of said bell crank levers, a lever engaging said link intermediate its ends, a remote control, and a sheath cable connection between said remote control and said lever for moving said lever and link in one direction and thereby displacing said wheels angularly about the pivots of the bell crank levers, and a spring connected to said lever to move said lever and link in the opposite direction.

3. A toy vehicle comprising a frame, a pair of bell crank levers mounted on. vertical pivots on said frame and each carrying a wheel at one end, a link for connecting the free ends of said bell crank levers, a right angle lever, one end of said lever being connected to saidlink intermediate the ends thereof, a spring connected between another end of said right angle lever and said frame,

a remote control comprising a pair of rela-.

tively displaceable elements, a second pair of relatively displaceable elements of which one is secured to the frame of the vehicle and the other engaged with the right angled lever, and a sheath cable connection between the pair of elements in said remote control and said second pair of elements whereby upon relative movement of one element in the remote control, the element connected to the right angle lever is similarly moved so that said wheels are displaced angularly about the pivots of said bell crank levers.

In witness whereof I have hereunto signed my name this 1st day of March, 1929.

HARRY FROW COGGON.
