Application filed December 3, 1927. Serial No; 237,434.

This invention relates to toy railways and more particularly to a novel means for con-- trolling an electric-a1 circuit to a signaling device or other accessory, and having a wide 5 range of adjustment and application to permit a steady or flashing light in the case of a signal, or continuous and intermittent operation of an electro-mechanical accessory.

To that end the invention contemplates a novel device in the form of a track attachment which may be fitted to any of thesta-ndard 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 thereover to produce the novel use desired, in accordance with the particular or selected setting of the device to give either a continuous, intermittent, or temporary operation or signal while 2 the car or train is passing through the section of track to which the device is applied,

Heretoifore, it has been the practice to employ a track section wherein one of the Wheel bearing rails is insulated at each end from the adjoining connected railof adjacent sections by the use of fibre joint pins or the like,

so that a signal or otherele'ctro-mechanical accessory included in circuit with such in-- sulated rail would be actuated by the closing of the circuit through the insulated rail when the car or train passes over the specially provided insulated rail of the signal track section. This arrangement, however, not only requires the use of a special track section, but permits of the circuit eing only continuously closed while the car or train is passing over the special track section, and in the case of a signal light, the same is maintained illuminated the entire time the. car or train is passing through the special section. Also, where a crossing gate, semaphore, or other electromechanical accessory is employed the circuit through the motor or solenoid thereof will remain continuously energized while the train is going through the special track section. In all cases, however, the'accessory is continuously operated due tothe fact that one or more wheels of the car ortrain are always on the insulated rail to maintain the circuit closed. Therefore, there is no opportunity for changing the character of accessory where a special track section is used which in-.

cludes a wheel bearing rail insulated from rails, by insulated fibre joint pins. 7

. Accordingly, the present invention has, primarily in view a simple, practical and reliable device in the form ofan attachment for a standard track section wherein both of the wheel bearing rails are grounded to the metal this and only the third rail is'insulated, and w characteristics which permit of the operator producing a flashing crossing signal, employmg one or more lamps, or to give a continuously illuminated warning signal while no car or train is passing over the attachment; or, ,on the other hand, permit of giving a flashing lamp signal only when a car or train is passing over the attachment.

A further object of the invention isto pro- .vide a devicethat is self-contained, simple in construction; easily and readily installed by an inexperienced person; which can be conveniently handled and packed for shipment; and can be readily installed at any point in the track system without taking-apart anyof the track sections or in any way disturbing any of the operating factors of the system. i In thatconnection, the invention also contemplates a dev ce which will operate on one or more signalmg devices at either high or low voltage.

. 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 stan ard track section. havingthe present novel attachment applied thereto. Figure 2 is a side elevation of the attachment shown in Fig. 1, the track rails being shown in section.

the tie and from adjoining wheel bearing 10h possesses novel structural features and in the accompanying Figure 3is a view similar to Figure2 showing the wheels of a car passing over the'track section and depressing the circuit controller of the attachment.

Figure 4; is a detail side elevation of the construction shown in Fig. 3 illustrating the circuit controller is'held and depressed by SPBCiZlVGl both of the wheels of the truck.

Figure 6 is a detail plan view of the yielding support for the circuit closing contacts and showing the manner in which the contacts may be moved into and out of operative position.

Figure 7 is a detail perspective view of the extensible contact shoe.

- Figures 8 and 9 are pers ective views reof the top and ttom electrical contact ngers.

Figure 10 is a diagrammatic view illustrating the circuits involved.

Similar reference characters designate corresponding arts throughout the several fig ures of the rawings.

In carrying the invention into effect, it is proposed to provide a track attachment including a base A having a fixed abutment B for engaging the rail R of a standard track section T, and an adjustable clip G for engaging the rail R the said clip being made-fast to the base by means of a fastening C or its equivalent.

The rails R and R are carried by the usual metal cross ties T and may be in electrical contact therewith as shown in Fig. 1 while the third rail R is insulated from the tie T as in dicated at T. It will thus be clear that the present device is adapted to be used in connection with a track section having only the usual insulated third rail which has the advantage of permitting the device to be easil and quickl connected to any part of a tree railway a ready set up without the necessity of taking'the track apart and inserting a special section having an insulated wheel bearing rail. Therefore, the base A is grounded to the wheel bearing rails and carries at one end thereof a terminal clip D to which .the ground wire of the signal'device may be attached.

As will be seen from Fig. 2, the base A is preferably depressed at its medial portion beneath the third'rail R thereb to permit of the free swinging movement 0 a novel circuit controller designated generally as E and having a pluralityof circuit closing brush contacts or fingers which may be selectively positioned for contactwith the electrically charged third rail to produce or control the desired ty of signal. 1 h

ferring more particularly to the novel circuit controlling device E it will be observed that the same essentially includes in its organization, a yieldable supporting member 1 preferably in the form of a flat spring which is rigidly connected as indicated at 2 to a por tion of the base A adjacent the wheel bearing railR. This sprin support projects transversely across the epressed portion of the base A and is adapted to be placed beneath the third rail B when the attachment is applied to the track. Therefore, in order to prevent a grounding of the third rail circuit, the upper surface of the spring 1 is covered with an insulating sheath 3. In addition to being provided with the insulation 3 for protecting the upper face of the spring, a block 4 of insulation is employed for supporting, on opposite sides thereof, the top and bottom circuit closing brushes 5 and 6, the former being adapted to overlie the base flange of the third rail R andthe latter being adapted to underlie the base of the third raid in such a manner that only one of the contact fingers engages the-third rail at a time, providing of course that both of the contact fingers are "at in a po-' sition for rail engagement. That it to say, the

- contact fin ers 5 and 6 are secured to the insulation 4 the eyelet members 5 and 6 which permit of the same being pivotally swung from the position shown in Fig. 1 for example, to the position shown in Fig. 6, so that either one or both of the contact fingers may be moved to a position to avoid third rail 1 engagement. I that way, the attachment may t e signal or accessory to be operated, the said signal accessory being of course, included in a ground circuit by the wire G connected with the grounded terminal D previously referred to. v

For the purpose of actuating the yieldable support or spring 1 to move the contact fingers 5 and 6 into and out of engagement with the third rail R, a novel wheel controlled actuator is employed. This actuator is preferably in the form of a shoe designated generally as S and carried by the bracket 7 whose lower arm 8 is secured to the free end of the yieldable support or spring by .suitable fastenin'gs 9. The upright wall of the-bracket is provided with an opening 10 for receiving a fastening 11 which cooperates with a slot 12 in an extensible member 13 which forms the upper side of the shoe S and is slidable on the stationary bottom part of the shoe 14 which is preferably a part of the bracket 7. To avoid derailment of the train, the opposite ends of the members 13 and 14 constituting the depressible shoe are inclined downwardly as indicated at 15.

Clearly, the wheel bearing length of the shoe S may be varied by adjusting the extensible part with reference to the fixed part, and infact the extension of he shoe to the lit full length of a track section would be merely a matter of degree so that when a length of the train to thereby hold the upper contact finger 5, for example, in engagement with the electrically char ed third rail R to produce a continuous ow of current to the signal device. On the other hand, by shortening up the shoe the ieldable support or springl will be caused to move more rapidly or oscillate under the alternate depressing and releasing thereof by the wheels of the moving train to produce an intermittently flashing signal due to the alternate engagement of the contact fingers 5 and 6 with the third rail, resulting in the simulation of a flashing crossing signal of the typeused at standard railway crossings.

Figure 10 of the drawings illustrates diagrammatically the manner of connecting a' flashing li ht signal ,to the attachment, the said sign including the lamps F and F which are electrically connected with the third rail R by the electrical connections L and L which lead to the contact fingers 5 y and 6 respectivel The frame of the signal is connected by t e ground wire G with the ground terminal D of the attachment and with the ound terminal D on the frame of the signa The lamps F and F are of the usual single contact t pe, the other contact for the lamps being t e grounded frame of the signal.

Assuming that the attachment is applied to a track section as shown in Figs. 1 and 2 and that the third rail R is electrically charged, the lamp F of the si al will be illamina-ted,- due to the contact. lir i ger dengaging the underside of the rail. If it is desired to'utilize a singe lamp to produce a flashing signal when the-train passes over thepoint'of installation of the attachment,

" the upper contact finger 5 may be swun out of the way to avoid striking the thir rail when the member 1 is depressed .by the wheels of the car which will carry the contact finger6 away from the base ofthe rail and tem )orarily darken the lam On' the other hanil, if'a double lamp flas er signal is desired, the contact fingers 5 and 6 may remain in the position shown in Fi 1 and 2 so that as the wheels W of the car a ternately depress and release the shoe S, first one signal lam and then the other will be illuminated. f it is desired to illuminate the lamp F for longer intervals or continuously while a car or train is passing over the attachment, it is only necessary to lengthen the extensible shoe S to such a degree that the shoe will be depressed by the wheels of one of the car trucks at? all times thereby holding the finger 5 in engagement with the third rail.

If it is desired to leave the attachment in track and yet render it inoperative, both of the contact fingers 5'and 6 may be moved to the position shownin Fig. 6, thereby to clear the third rail R".

Many novel lighting and signaling efi'ects can be obtained through the use of the double lamp type of flashingsignal shown in Fig. .10. For instance, the lamp F which is-in circuit with the bottom contact 6 may be green so as to indicate that the crossing is clear while 'notrain is approaching the location of the 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 chan es in the form, proportion and minor detai s of construction may be resorted to, without departing ,from the spirit of the invention and scope of the appended claims.
