ERNST PAUL LEHMAHN PATENTWERK, OF BRANDENBURG-ON-THE- HAVEL, GERMANY TOY MOTOR GAB Applicationfiled July 30, 1928, Serial No. 296,296, and in Germany December 23, 1927.

6 modern automobile to be represented as accurately as possible. This however is not done if a disc is arranged in the centre of a divided front axle, the inner ends of the half axles engaging therewith on both sides and displacing the half axles by their rotation.

Now in order to attain the desired object while still preserving the parallelism of the front wheels, it has also been proposed to divide the axle into three parts, of which the middle part is constructed as a lever oscillatable about its centre and adapted to be controlled at will. The two outer portions of the axle are oscillatable about vertical auxiliary pivots and are rocked backwards and forwards about the said pivots according to the movements of the middle portion, which engages with them on both sides. With this arrangement it has been found necessary to find an advantageous form for that part of the toy where thesaid auxiliary pivots intersect the outer portions of the front axle of the vehicle. This. problem has been solved by providing a cruciform piece'of sheet material and bending the four arms thereof in such a way as to produce four tubular elements, through two of which the wheel axle is passed, while the other two form the auxiliary pivot.

The present invention is diagrammatically illustrated by way of example in the accompanying drawings, in which all the parts that.

I are not necessary for the comprehension of the nvention are omltted.

In these drawings Figures 1 and 2 are diagrammatic views of the entire mechanism from above and from the side respectively.

In these figures, 1 is the s indle about which the centralportion 2 of t e front axle oscillates when a steering mechanism, not shown,'-acts u on it. 3, 3 are pieces of sheet material whic are mounted one at each end of the central portion 2 of the axle, and

through which the stub axles 5 of the front wheels pass at 4. v These stub 'axles 5 oscillate about auxiliary pivots 6 when the middle portion 2 of the front axle oscillates, and thus bring the wheels 7 into the desired position.

Figures 3 to 5 illustrate the employment of 7 this arrangement upon the front part of a toy motor car,

Figure 3 being an under side view,

Figure 4 a front elevation, and

Figure 5 a side elevation.

In these three figures the reference numerals 1 to 7 have the same meanings as in .Figs. 1 and 2. 8 is the frame of the motor car and 9 the front portion thereof. From this front portion flaps or

lugs

10, 11 and 12 are bent so as to serve as bearings for the auxiliary pivots 6.

Figures 6 to 9 show the special construction of the intersecting pivots on a larger scale. 13 is a cruciform piece of sheet iron or other sheet material. 5 is a short length of wire,

which is flattened in the centre at 14, and which forms the axle for one of the front wheels. This piece of wire is placed upon the piece of sheet material 13 and all the four arms of the latter are then bent up to form tubular sleeves, two of which constitute the auxiliary pivot 6, while the other two embrace the wire 5, which is prevented from rotating relatively thereto by the flattened portion 14.

The arrangement of the intersecting pivots described above. may be used not merely. for the particular purpose mentioned but also for other purposes in toys, clockwork mechanisms orthe'like, wherever a wire pivot has to be made rotatable or oscillatable about a pivot intersecting it either at right angles .or obliquely. If the pivot 5 is also to be rotatable, the pivot is leftunfiattened at 14, as

shown in Figure 10.

What I claim is A toy motor car comprising a-car body, a two-armed lever pivoted to the car body and oscillatable in a substantially horizontal plane, stub axles oscillatable in a substantially horizontal plane, steering wheels rotatably mounted on the outer ends-of the stub axles, the ends of the two-armed lever being adapted to engage with the inner ends of the stub axles and oscillate them for steering purposes without disturbing the parallelism of the steering wheels, and pivotal members each consisting of a cruciform piece oi sheet material, the four arms of which are bent into the form of sleeves, one pair of opposite sleeves of each pivotal member being bent round one of the stub axles and the other pair of opposite sleeves constituting a pivot for pivoting the stub axle to the car body.

1 In testimony whereof I have signed my name to this specification.
