This invention relates to toy railways and more particularly to a novel means for controlling an electrical circuit to a signalling device or other toy railway equipment.

I To that end the invention has as a general object a novel device in the form of a track attachment which may be fitted to any of the standard track sections generally used in connection with miniature track layouts, and which is controlled automatically by the passing of the wheels of the cars or train thereon to produce the novel use desired. A primary object of the invention is to provide a universal attachment for standard toy electric track sections which may be used to operate either of the two types of signalling devices now generally known in the art. That is to say, the present attachment is adapted for use in connection with signals of the semaphore or crossing gate type, or visual or audible signals which require an intermittent supply of current. Heretofore, it E has been necessary to provide a preconstructed unit involving a signal and a special track section equippedeither tooperate a signal by current supplied while the train is passin through the entire length of the special trac section, or on the other hand where an inter mittent type ofcurrent has been necessary, it has been the practice to place a device adjacent the track which would be intermittently struck by the wheels of the passin train to rovide an intermittent source oi current. Vith the present invention, however, the single attachment may be used to erform two dual functions of devices hereto ore employed, while at the same time efi'ecting considerable economy in the matter'of manufacture and also giving a wider range of use to a single device than heretofore known since the present attachment can be applied to any standard track'section by the user without the necessity of utilizing any special insulated track sections whatever.

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 prefcrredand practical embodiment of the invention is shown in the accompanying drawings in which Figurel is a plan view of a track section having the present improvement applied thereto and connected to a toy signalling device.

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

Heretofore it has been the general practice to use a special track section with one or more of the Wheel bearing rails insulated from the ties and from connecting rails by means of fiber pins and the like, the said special track section having wires connected thereto leading to the signal or other piece of equipment to be controlled. 'When a train passed over the insulated rails of this special track section the signal or other device was actuated through the closing of the circuit. 7 Such will be apparent from the following descriptlon.

, Referring to the drawings, A designates a standard track section including the wheel bearing rails 1-1 in metallic contact with the ties 2, and a third rail or current carrying rail 3 insulated from the ties as indicated at 4. p

The present novelattachment is designated generally as B and is shown as connected by the wire cord C with a signal or equivalentdevice SQ A distinctive feature of the attachment B is that it is not applied to the wheel bearing rails of the standard track section A, but is supported by engagement with the cross ties or sleepers thereof. Heretofore, where attachments have been used it has been customary to support them on the wheel bearing rails but. the present invention connects the attachment to the ties. and at the same time makes it possible to disassociate the signal and its attachment from the track section in such a way that the attachment can be applied to any standard track section which includes the metallic wheel bearing rails in contact with a metallic tie and a third rail insulated from the me tallic tic. Fhe attachment B is universal or duplex in its fundamental characteristics since as it will be later observed the c0nstruction is such that when the attachment is applied as shown in full lines of Figure l. the part 5 thereof will be engaged with the wheels of the train for an unbroken or continuous period of greater length than when the attachment is shown in the dotted line position of Figure 1 wherein only the spaced olfset ends 5 of the member 5 are adapted for wheel engagement thereby providing spaced circuit closers which provide for an intermittent flow of current to the signal S.

Referring more particularly to the attachment B it will be observed that the same includes a metallic wheel contacting strip or plate 5 having at one-side thereof an offset portion 5 and on its opposite edge a continuous straight side. Clearly-the offset portion 5 may be duplicated as often as desired, but as shown, two offsets 5 are illustrated. This metallic plate or strip 5 is connected by suitable fastenings 6 at its opposite ends to the insulated strip members or bases 7, and said bases'are in turn connected by fastenings S with spring attaching clips 9 having the downturned clamping ends 10. These clips 9 are adaptedto engage over or with the sleepers or cross ties 2 of the track section. Thus, it will be'apparent that the attachment B including the plate 5 may be readily mounted on any standard tracksection, and likewise detached when desired. It may be placed with the long edge adjacent one of the wheel bearing rails as shown in full lines in Figure 1' or it may be placed with the short edge constituted by the'member 5 adjacent the other one of the wheel bearing rails as shown in dotted lines in Figure 1.

The signal or other piece of equipment designated generally as S may be a bell signal 'as shown, a lamp signal, semaphore, or the like. lVhatever type the signal S may be it' shown in the drawing it is secured to the plate 5 by one of the fastcnings 6 for convenience so that the attachment maybe connected with one of the wires of the signalling device leaving only the other wire 11 to be connected by the user to the third rail 3 after the unit B has been placed in a desired position between one of the wheel bearing rails and the current carrying rail.

W hen the attachment A is applied to the track section as shown in full lines in Figure 1, it will be apparent that the plate 5 is yieldingly mounted due to-its being supported by the spring clips 9 so that itnormally lies in the path of the flanges F of the wheels \V of the car. \Vhcn the flange or flanges F or a wheel or wheels running on the wheel bearings L-1 contacts with and depresses the plate 5 it will be apparent that a circuit will be closed to the signal device S. As is well known the wheel bearing rails 1-1 mounted on the metallic ties 2 constitute one part of the electrical circuit while the insulated third rail constitutes the other part of the circuit This clip is preferably for supplying propulsion current to the mo-' tor or locomotive. Therefore, since the wire 11 is connected to the charged third rail 3, when the flange of a wheel completes the circuit between the plate 5 and one of the wheel bearings 1, the circuit will be completed to the signal S or other piece of equipment.

In this way, the equipment will be actuated as long as the wheels of a passing train maintain the circuit closed between the wheel bearing rail and the plate 5. The length of the straight side of the plate 5 is sufiicient to span the distance between the truck hearing the wheels of the cars, and, therefore, a. continuous supply of current will be sent to the apparatus S as long as the train is pass ing over the section equipped with the unit B. If, however, the apparatus S is of a flashing nature and requires an intermittent supply of current, the unit B may be removed from the track section and replaced with its unit B the same will make contact only m0- mentarily with the parts 5" thereby causing an intermittent supply of current to the aparatus S. Thus the unit B will be seen to e of a universal nature both for a continuous or intermittent supply of current to an apparatus S.

Without further description it is thought that the features and advantages of the invention will be readily apparent to those skilled in the art, and it will 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.
