#1 Claims.

The .present invention relates to toy railroads, and is more particularly directed toward toy railroads wherein current from two insulated Wheel bearing rails is employed for train oper-ation.

The present invention contemplates a toy railroad having the two insulated Wheel bearing rails and wherein two vehicles, such as locomotive and tender, are designed cooperatively so that appar-atus carried -by one of these vehicles connected to one of the rails is connectible to the other rail through the other vehicle.

According to the pres-ent invention the locomotive has all the wheels which cooperate With one of the track rails insulated and at least some of the wheels (preferably the drivers) which cooperate with the other rail act as collector shoes to carry current to the frame of the locomotive. The frame of the locomotive is connected to current consuming devices, such as propulsion motor, and this propulsion motor is connected through a jumper to the wheel bearing rails on the opposite side of the tender which act as shoes to conduct current to the other rail.

The invention also contemplates that the tender may carry an additional current consuming device, such as a whistle, and that this Whistle will have one side .permanently grounded to the frame of the vehicle and the other side connected to the running gear of the tender. The frames of the tender and locomotive are conductively coupled usually by a drawbar, and it is thus possible for the circuit of the current lconsuming device carred on one vehicle to be completed through Wheels forming part of the other vehicle.

The accompanying drawings show, for purposes of illustrating the present invention, one of the many embodiments in which the invention may take form, it being understood that the drawings are illustrative of the invention rather than limiting the same.

In these drawings:

Figure 1 is a diagrammatic top plan View illus'- trating a locomotive and tender with associated current consuming devices;

Figure 2 is a longitudinal sectional View through the bottom of the frame and the trucks and associated parts of a tender;

Figure 3 is an inverted plan view of the tender; and

Figures 4 to 7, inclusive, are cross sectional viewson the correspondingly numbered lines of Figure 1..

In the drawings two track rails indicated at ID and II are insulated from one another `and form parts of a track layout. This may .be either of the 2-rail or o1" the :all insulated, 3-rail type, but, if of the 3-rail type, the third or central rail Will be inactive. K

The locomotive carries a conventional propulsion motor M and reverser R. One terminal of the motor-reverser circuit is connected as indicated at I2 to the frame of the locomotive. The other terminal of the motor-reverser circuit goes to an insulated receptacle I 3 which may -conveniently -be mounted in the cab. The propulsion motor M is mechanically connected to axles I4 carrying driving Wheels I5, indicatedfon the upper side of the ligure as grounded to the frame and opposite driving wheels I5 insulated from the axles, as indicated in'rFigure 4. The locomotive also has unilanged driving Wheels I6 and I'I, the latter being insulated from the axle, as indicated in Figure 5, and has pilot trucks I 9 and 20, all of Whose Wheels on the lower side of Figure 1 are insulated from the axles. This insulation is indicated at 2| in Figure 6.

It will thus be seen that the current consuming devices carried by the locomotive are permanently connected to one side of the circuit through the collector shoes in the form of Wheels, as indicated in the upper side of Figure Land that these current consuming devices can only be energized by completing the circuit from the receptacle I3.

The locomotive is connected through a metallic drawbar 22 with the tender so that the body of the tender is at the same potential as the body of the locomotive. The body of the tender is indicated more in detail at 23 in Figure 2. The tender has two 3-Wheeled trucks, indicated at 24 and 25. These trucks are insulated from the body of the tender by insulating plates indicated at 26, 21 and insulating rings 28, 28. They are swivelly connected with the tender frame by studs indicated :at 29. These studs are rmly secured to the frames 30, 30 of the trucks.

Interposed between the frames 30, 30 of the trucks and the insulating plates 26, 2l are conducting `plates 3| and 32. The plate 3| has a soldered lug 33 connected to a Wire 34 which extends from the tender across toward the locomotive Iand has a pin 35 to cooperate With the receptacle I3. In this Way the truck 25, which has been insulated from the truck body, and which has insulated Wheels .35 on one side as indicated more .clearly in Figure 7, may act as a collector shoe in cooperation with the lower rail II and the circuit is completed from the` propulsion motor M to the rail I I.

An insulator 36 is secured to the central part This wire is connected to the circuit for a whis- Y tle motor and controller indicated generally at W, the other side of which is grounded as indicated at 42 to the frame of the tender. The circuit for the whistle motor is completed through the drawbar 22, the frame andvuninsulated running gear of the locomotive.

In the arrangement above described it is possible to complete the assembly of the entire locomotive with propulsion motor and reversing controller and to complete the tender with the whistle, motor and accessories and when they are coupled together by the drawbar and jumper, all the usual operations of the locomotive and whis- 'tle may be had by controls of the same type -which are used with the more usual 3-rail type of toy railroad. Furthermore the same equipment may be used with 3-rail toyl railroad track layouts of the type in which the wheel bearing rails are insulated from one another, as, for example, with track sections in which the wheel bearing rails are carried in molded insulating bodies The arran ement shown makes it possible to place practically the entire weight of the locomotive on the drivers so that most efhcient traction is secured and current collected from one wheel bearing rail, and at the same time avoid splitting the axles. Here the axles are solid and power is transmitted to the drivers in the usual way. The pilot trucks are not suitable for use as current collectors as they do not make good contact. The tender which carries the whistle as usual is heavy and makes good contact through all the wheels on one side.

It will, of course, be obvious that the connections may be rearranged so that the locomotive motor circuit could be completed through the drawbar and the tender circuit through the plug and receptacle.

t is obvious that the invention may be embodied in many forms and constructions within the scope of the claims and I wish it to be understood that the particular Vform shown is but one of the many forms. Various modifications and changes being possible, I do not otherwise limit myself in any way with respect thereto.
