Application November 16, 1938, Serial No. 240,800
In Germany November 18,- 1937 Claims.
The invention relates to elect'ric toy railways,
and especially to toy locomotives, motor trucks, tenders and the like, and concerns the insula tion of the track wheels of same.
5 The current taken up by the track wheels from the feed rails, must not how into the other parts; and, in particular, must not be conducted further through the gear wheels transmitting rotational movement to the other track-wheel axles.
19 In a known arrangement, the track wheels are seated on bushes of non-conductive material, and the gear wheels located in rear of the track wheels are also of non-conductive material. Since, owing to the small space available these latter can be only very weak, their working lifeis short by comparison with the other parts. It is also disadvantageous that the gudgeon pins of the crank rods must also be insulated at the various points'of attachment, and this is a rather difficult matter owin to the small dimensions of these members, and very troublesome by reason of the number of insulations required.
In the case of toy railway designed in accordance with the invention, these drawbacks are 2 remedied by arranging a disc of non-conductive material behind the flange of the track wheels, or by making the flange itself of non-conductive material; or also, by inserting an insulating plate on the outer side of the track wheels, between these and a disc serving to mount the gudgeon pins of the crank rods. This insulating plate is preferably secured to the track wheel by pres:- sure. I
The new design of the track-wheel insulation enables metal gear wheels to be employed for transmitting the rotational movement of the driven track-wheel axle to the other track-wheel axles, premature wear of these gear wheels, in
relation to the other parts being thus prevented.
.At the same time, none of the small amount of space available is ne ded for the insulation, since the flange efiects the insulation. Another advantage consists in that special insulation of the various crank-rod gudgeon pins is superfluous,
while, nevertheless, a guarantee is afiorded that these latter do not receive any current.
A typical embodiment of the invention is illustrated in the drawing, in which:
Figure 1 is a side elevation of a toy locomotive;
Figure 2 a section through a track wheel, with a plan of the adjoining track wheel, and Figure 3 a section through another embodiment of a track wheel.
The locomotive a. is provided with three pairsof track wheels h, mounted on the axles c.. The wheels I) are seated on bushings h, of non-conductive material. The gear wheels 2 and J serve to transmit the rotational movement of the driven track-wheel axle to the axles of the other an track wheels.
The flange b of 'the track wheels I) is partially (see Figure .2) or wholly (see Figure 3) constructed of a disc 9 of non-conductive material. This enables the gear wheels e and j to be made of metal, while no portion of the small space 5 available between the track wheels b and the undercarriage'o is required for the insulation.
Inserted on the front side of the wheels b, and between them and a disc k, which receives the gudgeon pins d of the crank rods, is a plate 1' of 10 non-conductive material. In this manner any passage of current from the wheels b to the crank rods is precluded. There is therefore no need for the individual insulation of the several gudgeon pins. 15
The insulating plate at is provided with a recess I in which lies the member-rivet head 1) in the example shown-securing the gudgeon pin d.
It is of particular advantage that the insulating plate 2' should be providedwith a projection 24) or the like m, which-can be formed, at the same time as the recess Z by pressing. This projection enters a corresponding recess in the wheel, thereby preventing the insulating plate 2' from turning in relation to the wheel.
I claim as my invention: 25
1. In an electric toy railway, especially toy locomotives, "an insulated wheel structure comprising a bushing of non-conducting material on which a track wheel is mounted, a plate of nonconducting material mounted on the front side 30 of the track wheel, and a disc adjacent the plate, said disc having a pin for 'a. crank rod mounted therein.
2. An insulated wheel structure according to 35 claim 1, in which the plate is provided with a recess to accommodate a member for securing the pin to the disc.
3. An insulated wheel structure according to claim 1, in which the plate is provided with a. projection and the track wheel is provided with 4 a recess, said projection on the plate engaging in the recess in the track wheel to prevent rota-' tion of the plate relative to thetrack wheel.
4. A wheel structure for toy railways, particularly locomotives, comprising a gear mounted on a shaft of the locomotive, a bushing of insulating material mounted on the gear, and a track wheel mounted on the bushing and having at least an integral part thereof constituting a flange ofthe wheel with the remaining part of the flange be- 50 ing, composed of the .bushing.
5. A wheel structure for toy railways, particularly locomotives, comprising a gear mounted on a shaft of the locomotive, a bushing of insula'ting material mounted on the gear, and a track wheel mounted on the bushing, said bushing comprising also a flange for the track wheel;
