Joseph L. Bonanno, Maplewood, N. J., assignor to The Lionel Corporation, New York, N. Y., a corporation ol' New'York Application October 21, 1938,-Serial No..236,24 1- s c aims. (or. 213-212) The present invention relatesto accessorycon trol circuits for toy electric railroads and apparatus therefor, and is more particularly directed toward arrangements for effecting the 51-- multaneous operation of two electromagnetically operated couplers on the adjacent ends of two cars, so that the cars maybe uncoupled, and to additional circuit arrangements and.;.cont"; ols' wherein a car-carried accessory, such asah'o'pper dumping mechanism, may be actuatedwithout uncoupling the cars. All of these controls and operations are carried out in a toy train outfit having a locomotive which can be operated in either direction, or stopped without disconnecting the power source from the track layout, so that power is available for operating the couplers or accessory when the train is standing still.

The present invention contemplates the provision of the track layout with a special section of track having in addition to the usual wheel bearing and power rails, two supplemental rails on opposite sides of the third rail, and the use with such track of a controller arranged either to bring both supplemental rails to third railpotential to simultaneously operate two couplers, each connected to a current collector bearing on the corresponding supplemental rail, or to bring one of these supplemental rails to' third rail potential. and the other one to ground potential so that a circuit can be established through the carcarried accessory for operating the latter.

Other and further objects Will appear as the description proceeds.

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

' In these drawings:

Figure 1 shows a wiring :diagram for a toy track layout having a train' provided with automatically coupled cars, a carried accessory, a piece of special track and controller;

Figure 2 is a top planview of the track section; Figure 3 is a transverse sectional view on the line 3 -3 of Figure 2;

Figure 4 is a top plan view of the controller; Figure 5 is a vertical sectional view on a line 55 of Figures;

Figure 6 is a transverse sectional view taken on the line 66 of Figure 5; and

- Figure 7 is a plan view of the control spring for the circuit controller of Figures 4 to 6, inelusive,

The special section of track shown in Figures 1 to 3, inclusive, is adapted to be substituted for an ordinary track section. It has an insulating base 10, two track rails, indicated at H and l2, the third rail, indicated at I3, also two supplemental rails l4 and 15. These rails are made of sheet metal bent to shape and each of the rails has fingers such as l4 extending down through vholes 'inthe insulating body, and these fingers anchor the rails in. place as well as electrically connect the corresponding rail with a contact. strap. Four such straps are shown at l6, ll, [8 and I9. The straps have binding screws 2|, 22,

- 23 and 24, so that it is possible to connect the wheel bearing rail l2, the supplemental rails l5 and I4, and the third rail I3 to an external controller by means of wires, such as indicated at 25, 26, 21 and 28. A circuit controller is shown in detail in Figures 4 to 7, inclusive.

The circuit controller is a small portable de vice adapted to be conveniently placed near the track layout and connected up by the wires such as indicated. It has an insulating body member 30 provided with a central downwardly extending square post 3| adapted to receive four contact strips or straps 32, 33, 34 and 35 spaced above one another, as will be apparent from the drawings. The body member is apertured, as indicated at 31 and 38, to receive pushbuttons 39 and 40. These push buttons bear on the opposite ends 4| and 42 of the upper contact strip 32 which acts as a control spring for the circuit controller, and holds the push buttons in the upper or normal position at which time .none of the contact strips are in electrical contact. When the left button 39 is pushed down it brings the left ends of strips 32, 33 and 34 into electrical contact and therefore brings both of the supplemental rails l4 and I5 to third rail potential. This establishes the uncoupling circuit to be described.

When the right-hand button 40 is pressed down it brings the contacts 32 and 33 together and owing to the interposition of an insulating spacer 43, the contact strip 33 is kept out of electrical contact with the contact strip 34, and this latter strip 34 is pressed down into contact with strip 35. The operation of this push button has therefore brought the upper supplemental rail l4 to third rail potential, and has brought the lower supplemental rail l5 to track rail potential. This establishes what is conveniently designated the dump circuit. x

In Figure 1 the power supply circuit is diagrammatically indicated at T, and the propulsion motor and associated automatic reverse mechanism at M. The power supply is usually in the form of a transformer with convenient switch and push button, and the control circuit M is of the type which permits starting, stopping and reversing the motor while keeping the power on the-tracks when the motor is not operating, so that lights and accessories can be energized.

The short heavy lines above and below the rails of Figure 1 indicate the length of a car Cl and the apparatus carried on this car is placed on the drawing between these two lines. This car stands on a section of track indicated in the figure. The apparatus on the locomotive L, which is on a regular track section 36 is illustrated at the right. Part of the apparatus of the second car C2 of the train which is on another section 31' regular track, is shown at the left. The car CI has a current collector 50 bearing on the supplemental rail l5. through a coil 5| and wire 52 with the grounded truck indicated at 53. This coil is adapted to actuate a coupler head diagrammatically illustrated at 55 whenever the rail I5 is energized. The front end of the car Cl carries a current collector 56 bearing on the supplemental rail l4,

and this current collector is connected through a coil 51 and wire 58 with the running gear of the other truck indicated at 59. The coil 51 is adapted to-operate a coupler head 60 whenever the supplemental rail 14 is energized. The current collectors 50 and 56 of the car Cl are connected to a circuit including a coil 6| of lower impedance than coil 51 and adapted to actuate an accessory carried on the car, such, for example, as the hopper for a dump car, a hoist, a. small motor, a whistle, a lamp, or some other accessory.

When the car is standing on the special section of track, as shown, operating the dump button 40 will complete a circuit through the coil BI, and will also energize the coil 51 of the coupler at the right end of the car, without, however, ef-

fecting an uncoupling operation, which as explained below requires concurrent operation of two uncouplers.

If it is desired to uncouple the locomotive L from the car Cl, the train is backed up a sufficient amount to bring the wheel 62 of the locomotive on to the special section of track. This will place the contact 50 on to the rail I5, and, when the button 39 is pressed down, current will flow through the coil 5|" of the coupler carried by the locomotive and will actuate the coupler head 55'. .At the same time current will flow from the supplemental rail H to the coil 51 and actuate coupler head 60. This will release the coupler head 60 from the hook 63 of the coupler carried by the locomotive and will release the coupler head 55' of the locomotive from the hook 64 carried by the car Cl,-so that the cars can be separated manually, or so that when the locomotive is again energized to start forward it will leave the train behind.

Similarly if it is desired to uncouple cars Cl and C2, the train is moved forward enough to bring the running gear of car C2 on to the special section of track. This will make it possible to energize the coupler coil 5|, and the coupler coil 51 carried by car C2.

Owing to the low impedance of coil 6| it is possible to avoid operation of the associated accessory should the coil and a coupler coil, such It is connected as 51, be in series, as, for example, when collector 58 of car Cl is just off to the right of control rail l4 and rails l4 and I5 are energized for the purpose of uncoupling cars Ci and C2. It is unnecessary to stop the train to uncouple cars.

It is obvious that the invention may be em bodied in many forms and constructions within the scope of the claims and I wish it to be understood that the particular form 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.
