OF CHICAGO, ILLINOIS, A CORPORATION OF ILLINOIS.

Application filed. February 16, 1926. Serial No. 88,717.

This invention relates to toy railways and more particularly to the contract holder for a self contained lighting system for 1ndividual cars.

In toy cars in which the interior of each car is illuminated by lamps located 1n the bottom ofthe car, the current supply unit is so constructed and arranged that it will pick up current from the third rail or other source irrespective of any other car in the train. In such structures it is desirable that the current supply unit or trolley be reliably held in contact with the third rail and that the use of conductor wires be dispensed with;

Accordingly, this invention has as a primary obJect the provision in cars of this character, of contact means yieldably mounted in such manner as to insure constant and positive contact with the power rail of a toy electric track. In that connection it is also proposed to provide a roller contact located on the rolling stock of the car for gathering the electric current from the third power rail and conducting it to a light socket located in the bottom of a toy railway car.

Another object of the invention is to provide a roller contact of this character designed to be mounted on the car axle and which includes a flat flexible spring to carry the electric current to the light socket, the

spring being constructed to also operate asa tension spring for maintaining the roller contact in constant positive engagement with the power rail of the toy railway track.

A further object of the invention is to provide a simple and durable contact of this character which may be assembled with great facility and in which all wires are eliminated.

With the above and other objects in view which will more readily appear as the nature of the invention is better understood, the same consists in the novel construction, combination and arrangement of parts hereinafter more fully described, illustrated and claimed.

A preferred and practical embodiment of the invention is shown in the accompany- 1ng drawings, in which:

Figure 1 is a side elevation, 'with parts broken out and in section, of an electrical toy railway car, embodying this invention;

F gure 2 is a transverse section thereof;

Figure 3 is a plan view showing the wheels and axles assembled with this improved roller contact mounted thereon;

Figure 4 is a perspective view of the roller contact support detached, with the roller shown mounted therein, and

Figure 5 is a detail plan view of the tension spring of the circuit connectors.

Similar reference characters designate corresponding parts throughout the several figures of the drawings.

In carrying this invention into efliect it is proposed to provide an individual lighting system for toy cars of the passenger or Pullman type, although it will of course be understood that the same may be readily applied to closed cars of other types wherein it may be desirable or necessary to provide illuminating means independent of the locomotive or any other car in the train, and which includes simple and eflicient means for insuring positive engagement of the roller contact with the power rail and avoids all use of conductor wires and the soldering incident to the connection of such wlres.

Accordingly, with these objects in view it is proposed to equip the car bottom des-. ignated generally as B with an interior socket including a screw shell contact S adapted to receive a lamp L, the said shell S being held in position by a center plug contact P which is insulated from the car in any suitable manner preferably by an insulating washer W which also insulates a spring 1 which forms a combined current conductor and spring tension for conveying the electric current from the trolley roller 10 to the socket lamp assembly from the third rail R.

The trolley or shoe unit 10 is carried by one of the trucks of the car and is shown 5. The axles A are covered with tubular insulators while ateither end of each axle on the inner sides of the car wheels are 1 insulating washers or disks 21 held in po- 'sitionby the car axle.

7 These insulating disks and tubes cooperate to completely insulate the conductor roller 10 from the car frame or truck.

The holder 5 for the contact roller 10 is shown in detail in Fig. 4 and is struck out from a sheet metal platewith the body portion 6 thereof provided with depending ears 7 to form bearings for the journals 11 of the roller 10. At one end of the body member 6 is an upwardly and outwardly curved hook-like member 8 designed to extend over one of the axles A as is shown clearly in Fig. 1 and which operatesas a guide or stop to prevent the roller holder from getting out of place. Extending longitudinally from the other end of the body 6 is an axle encompassing hook-like member 9 designed to extend around an adjacent axle A as shown in Fig. 1 with a T-shaped element 12 projecting from its free end and overlying the body member 6. This member 12 is desi ed to be engaged by the slotted end 3 a combined tension spring'and electric conductor 1 which is connected by its end 2 with the contact P of the lamp L as isshown clearly in Fig. 1. This spring 1 is curved longitudinally and exerts its tension when connected with the holder 5 to thrust downward on the contact roller 10 and insure a positive connection of the roller or shoe with the power rail R. It will thus be seen that this spring 1 acts as a lead-wire for conducting the electric current from the contact roller 10 to the socket lamp assembly as well as to yieldably hold the roller in engagement with the power rail.

The axle engaging member 9 of the holder 5 is also provided with pliable tongues 13 which are adapted to be bent around the car axle A, as shown in Fig. 1, and these tongues in connection with the hook-like member H prevent the holder from being disengaged when the car is lifted from the track.

From the foregoing it will be apparent that when the car is placed on the track which includes the wheel bearing rails R and R in addition to the third or ower rail R the roller 10 will yieldingly an persistently follow and engage the third rail R due to the fact that the holder 5 which carries it is under com ression from its engagement by the com ined tension spring and conductor 1. Therefore, while the car is on the rails, standing idle or travellin current will be fed from the third rail through the roller 10 holder 5, spring 1 and center plug contact l of the socket within the car. The screw shell contact S is ground on the 'car which in turn through the wheels thereof is grounded to the rails R and R and the circuit to the lam L will be-completed. It is of course un erstood that the rail R is supplied with current from a suitable source as is also the rails R and B when the track-wa is insulated.

It will also be 0 served that by connecting the current conveying spring 1 with the roller holder 5 by means of the slot and tongue connection the roller 10 may readily follow the curvature of the third rail along the tracks without disturbing the position of the spring 1 and that a positive electrical connection is formed between the holder 5 and spring 1 without necessitating soldering of any parts.

Without further description it is thought that the features and advantages of the mvention will be readily ap arent to those skilled in the art, and. it Wlll of course be understood that changes in the form, proportion and minor details of construction may be resorted to, without departing from the spirit of the invention and scope of the appended claims.
