Application filed 0ctober 24 1925. Sean -No.- 64,645.

This invention relates to toy electric railways. Among the objects of the invention 1s to provide a device of the character described which shall comprise comparatively few and simple parts, shall be readil attachabledirectly to the toy track, an ef ficient in operation to a high degree.

Other objects of'this invention will in part be obvious and in part hereinafter pointed out.

Certain features herein shown, and described are shown, described, and claimed in my 'co-pending application Serial No;

features of construction, combinations of elements and arrangement of parts, which will be exemplified in the construction hereinafterv described, and of which the scope of application will be indicated in the following claims. Q In the accompanying drawing, in which is shownone of the various possible illustrative embodiments of this invention, Fig.1 is a perspective View of a toy railway installation equipped with an improved automatic train stopping and restarting control and signaling devicelembodying the invention; o I .Fig. 2 is a diagrammatic view of the wir- 1 ing system and a perspective View of the rear side of the control device panel;

. Figs, 3 and 1 are cross-sectional views taken on lines3-3 and 4- 1 in Fig. 2 showingv the contacts in their normal position;

and I Fig- 5 is a fragmentary view of a portion of the third/rail showing partsfbroken .away to show the pin connection.

Referring in detail to the drawing,'the invention is there shown applied to a. toy railway tracksystem comprising two

main rails

10, 10?, usually. attached in proper spaced relation to eachother and at suitable lengths by means of cross ties 11, the connection between the rails and cross ties indicated at 12being of any convenient or conventional type, and a third or power .rail 13 extending between the main rails 10,

The invention accordingly consists in the- 10*, which is securedto the cross ties, said rails being constructed in the well known manner and supplied with'power fromany suitable source (not shown) through the conductor wires 18. The tracks are preferably made in standard sections joined together by means of a pin and socket connection in the well known manner.

At any desired point along thetrack, as

forexample, in the portion passing a station indicated at in-Fig. 1, a section 13 is nsulated from the remainder of the third rail as at 13*" and 13 by replacing pin 14-. (see Fig.

An automatic train'stopping and restart-' the usualmetallic connector pins by'a fibre a unit in a toy tower 16, and isjpreferably connected to-the track system by a binding plate 17. Extending from the base portion 17 of said plate are spaced

arms

19 and 19 which are of sufficient length to reach be neath the rail 10, and also beneath'andfbeyon-d the third rail 18.

Currentcarrying strips

21 and 21 may be insulated from and secured to the under side of the arms '19 and 19 respectively, each strip extending beyond the free end of the arms 19 and l9tan'd being upturned to form

contact clips

22 and 22 respectively for engaging the rail 13. The other ends of said strips opposite said clips may be constructed to pass through the base ortion 17 and connect withquick detacliable binding or'terminal posts A and B. j A grip lever 23 is pivoted to said base portion between the binding post for engaging with the outside flange of the rail 10, i. e. the side remote from the third rail to firmly'and v positively anchor the binding member 17 to the tracks, and suitable means such as binding or terminal 7 post for connecting the'rail 10 to the control device 15 may be also provided. Thus, as will be seen from Fig. 1, the

current carrying strips

21 and 21.

are brought into close contact with the third rail and with the insulated rail section 13 in conjunction with which the device 15 opcrates, as will hereinafter appear.

The device 15 is seen to comprise a thermostatic control switching mechanism mounted on a panel 25 and two

semaphores

26 and 27, said device being preferably constructed to form a unit by installing the mechanism and panel in the tower base- 16, and the semaphores at the top of the tower as shown in Fig. l. The tower and semaphores are preferably constructed and arranged to simulate in appearance like apparatus used in actual railway signal work, the semaphores comprising a green and red

transparent window

26 and 27 in the tophousing of the tower 16 through which

lights

26 and 27 respectively, are arranged to show for flashing signals controlled by the device 15.

The thermostatic switchv control mechanism of the device 15 is seen to comprise a flexure member 28 which has one end anchored by a screw 29 on a raised support 30 so that the member 28 is spaced from the rear side of'the panel. Carried on and extending transversely of the free end of'the member28 is a switch blade 31 which when flexed out of a normal position bridges spaced

contacts

32 and 33, fixed to the rear side of the panel 25, the mid-portion 31 of said blade being adapted to engage a contact 34" when the member 28 is raised to its normal position, said contact 34 being mounted to project downfrom an overhanging end of aZ-shaped support 34 secured to the panel 25 as shown in Figs. 2 and 3.

Any suitable heating means may be proyided for effecting the fleXure of member 28, as for example a plurality of turns of heater wire 45 wound over an asbestos or like insulating covering 46 on said member 28. One end of the wire 45 and the end of the .member 28 at screw 29 may be connected with the terminal post A, by means of conductor wires 47. g

A hook ended lever 49 for manually throwing the device 15 in and out of operation is provided; said lever having a handle 49f extending out from the front of the panel 25 and pivoted to an angle piece 50 mounted on the rear side ofthe panel 25. The hook end of'the lever is adapted in one extreme position thereof to engage the member 28 for depressing same and making the device ineffective.

The operation of the device will now be clear.- The locomotive is represented in the drawing by wheels, 51 which are driven by motor 52, the latter receiving power in the well known manner from the track 10 through ,a contact shoe 53 riding on the third rail and through the wheels 51.

Assume the train to be traveling in the direction indicated by the arrow shown in Fig. 1 and the lever 49 disengaged from-the member 28. Before the locomotive reaches the insulated section 13 of the third rail, the parts of the automatic train stopping restarting and signaling device are in their normal effective position shown in Fig. 3

and in full lines in Fig. 4, the current pass-- ing from the main line portion of the third rail 13 through the current carrying strip 21 to binding post A, and thence to the conductor wires 47. The current through wire 47 passes through the inember 28 and blade 31to the contacts 34 on the support 34 and from abindingscrew 55 on the latter connects throughaconductor wire 61 with the terminal 27 of the lamp 27 positioned behind thered colored window 27 in the track which includes the insulated section 13?. the direct power circuit to the "shoe 53 and the motor 52 is interrupted. The cur.- rent then flowing" to the motor 52 is supplied through current carrying strip 21 to binding post A, and thence through conductor wire 47, heater coil 45, bindingscrew 42, on an upstanding side of an L-shaped member 40 which is secured on the rear side of the panel 25 andhas mountedthereon the contact 32. From the member 40 the current passes through a conductor wire 48 having one end "secured under a binding screw 43 on said member 40 to binding post B, current carrying strip 21 to the insulated rail section 13 which connects through the shoe 53 with the motor. 52. I g

i It is apparent that due to the resistance of the heater coil in'series with the motor 52, the power tov the latter is materially reduced and the train stops because of insuflici'ent power supply. After a short inter val of. time the heater coil 45. due to the flow of current, heats the fieXure member 28 sufiiciently to cause it to flex from its normal position to that shown in dotted lines 1 in Fig. 4.

The movement of member 28'swin'gs the blade 31 and breaksthe circuit at contact 34 thus extinguishing the light 27 behind the red colored-window, causing the blade 31 to engage contact 32 and current toflow through a jumper 54 on which the contact 33 is] mounted to a wire 57, secured thereto by means of binding screw 41, and connecting V with one terminal 26 of the lamp 26 being positioned behind the greencolored window 26 in the tower 16. The other terminal of the lamp 26 is permanently grounded as at G to the structure of the tower 16 from which the circuit is completed through the grounded rail 10, thus causing the green light to show in the tower.

The flexing of the member 28 also causes the blade to engage the contacts 32-and thereby permit the direct flow-ofcurrent from the third rail 13 to terminal post A through the wire 47, member 28, blade 31, L- shaped member 40, conductor wire 48, terminal B and strip 21 to the rail section 13. Full voltage is now impressed on the locomotive motor 52 which automatically restarts the-train. After the locomotive passes over the rail section 13 the currentthrough the heater coil 45 is cut OE and the member 28 is permitted to cool and to return to its initial position, thus automatically extinguishing the green and relighting the red signal.

To make the device 15 inoperative, the lever 49 is swung so that the hooked end thereof engages member 28, and is effective to retain said member and blade 81 out of their normal position. The third rail section 13 is thereby directly connected to the third rail 18, and the green light then shows continuously.

From the foregoing description, the advantages of the device and apparatus above described will be at once apparent.

It will be noted that the signal lamp and the electrical control mechanism for the lamps and the stopping and restarting of the train are all assembled and embodied in a neat and compact signal and switch tower unit which may be sold separately and readily connected to a standard toy railway track system, it being simply necessary in some manner to insulate a section of the third rail. To this end small fibre pins may be furnished together with the tower unit for replacing the metallic pin connectors, thus making the matter of connecting the standard electric toy outfit into one having the interesting train and signaling control features above described so simple as to permit installation-and operation by the average child.

It will be thus seen that there is provided a device in which the several objects of this invention are achieved and which is well adapted tomeet the conditions of practical use. I

As various possible embodiments might be made of the above invention, and as various changes might be made in the em-.

bodiment above set forth, it is to be understood that all matter herein set forth or shown in the accompanying drawing is to be interpreted as illustrative and not in a limiting sense.
