J. COOPER TOY RAILROAD TRACK Filed March v, 1927 '2 smu -sheet 1 mvENToR ATTORNEY Patented Nov. 19, 1929 JOHN COOPER, OF EVANSTON, ILLINOIS PATENT OFFICE TOY RAILROAD TRACK Application filed March 7,

This invention relates to improvements in track systems of toy railroads, the general object of the invention being to provide a switch whereby a train can pass from one track to a second track when going in either direction, so as to provide an eight-way switch, the major portions of which are stationary so that the switch can be ma'nufac tured to sell at low cost and is not likely to get out of order.

Another object of the invention is to pro- 'vide means whereby, when one switch has been moved, the other switches are locked against movement so that there is no danger of two trains coming together on one track.

A still further object of the invention is to provide means for deenergizing a part of the third rail of one track when the switch means have been set for a train to cross from one track to another and also to provide means for operating signals whereby danger signals will beset by the operation of the switch means against trains approaching the switch and clear signals will be set for the train which is intended to take the switch.

This invention also consists in certain other features of construction and in the combination and arrangement of the several parts, to be hereinafter fully described, illustrated in the accompanying drawings and specifically pointed out in the appended claims.

In describing my invention in detail, reference will be had to the accompanying drawings wherein like characters denote like or corresponding parts throughout the several views, and in which Figure 1 is a plan view of the improved system. 1 Figure 2 is a bottom plan View thereof. Figure 3 is a sectional detail view showing the spring frog.

Figure 4 is a sectional view through one end of one of the switch operating levers, showing the insulated contact thereon. In theseviews, 1 indicates a base which is formed with the usual flanges which are adapted to rest upon a floor or other support to hold the base spaced from said support. The base is formed with'the openings 2 for preventing contact of the various current straight rail 12 and a curved rail 13. Each 1927. Serial No. 173,481.

carrying means with the base. The base 'is adapted to be placed between portions of the track supporting means of the railroad at a point where the switch or crossing is desired to be located.

The main tracks are shown at A and B and the cross tracks at C and D, the rails of the main tracks of the switch abutting the rails of the tracks A and B. The outer rail of the track A is shown at 3 and the outer rail of track B is shown at 3, these rails being suitablyconnected to the base. A pair of convergent rails 4 is carried by the base at each end thereof, the inner ends of the rails being connected together and these rails form portlons of the inner rails of the main tracks and portions of the cross tracks. A pair of triangular shaped parts *5 and 6 are carried by the base and the base of each part forms a part of the inner rail of each track while its sides form parts of the cross tracks C and D. Four substantially U-shaped members E are carried by the base, each member having an. extension 7 on one limb thereof which forms a portion of the inner rail of a main track with its bight 8 forming a portion of a cross track and its limbs 9 and 10 forming guard rails for a cross track, the limb 9 being adjacent a side of a triangular member and the limb 10 being adjacent the cross track forming portion of each rail 4. j

A switch member F is placed adjacent each end of each of the main tracks of the switch and each member comprises a base 11, a

member F is pivoted to the base adjacent its inner end with its straight rail forming a "portion of the inner rail of each main track when the switch is closed and its curved rail forming a portion of a cross track when the switch is open, the straight rail abutting the extension 7 of the member E when the train is to continue along the main track.

A cross rail 14 is placed adjacent the inner end of each switch member between the rails of the main track and at an angle thereto for filling the gap between the curved rail 13 of each switch member and the triangular shaped member so that the wheels of a train will pass from the curved rail of each switch member upon each rail 14 and then pass onto the triangular shaped member.

From the foregoing it will be seen J that when the switch is closed, the wheels of a train passing along a main switch, will pass over the straight rail 12 of a switch member,

. thenthe extension 7 of the member E, then will pass over a side of one of the triangular members and then it passes over the bights 8 of two of the members E and then passes ofi the switch by engaging the side of the other triangular member, a curved portion of one of the rails 4 and the rail 14 of the other main track and the curved rail of the switch member of the said main track, the guard rails keeping thewheels on the cross track rails, as' will be understood. At the center of .the cross tracks angle-shaped rails 15 are provided for forming the guard rails.

A cross-shaped member 16 is arranged at the center of the cross tracks to form the third rails of said tracks and this member is insulated from the base, as shown at '17. A short rail 18 is placed in each end of each cross track to form a continuation of the third rail and these parts 18 are insulated from the base, as shown at19. The ends of the parts 16 and 18 are spaced from the bights 8 and are located over openings 2 and these parts 16 and 18 are electrically connected together, as

shown at 20, the electric connections passing under the bights 8. Each third rail of each main track of the switch comprises an enlarged part 21 which is located over .each switch member and these enlarged portions of each track are connected by the insulated section 22 which is arranged at the center of the main track and the depending parts 23 which connect the ends of the part 22 with the parts 21 and these parts 23 pass under the rails 14 and the inner ends of the enlargements 21. By providing these enlargements 21, the brush of a train can pass therefrom either upon the parts 23. and 22 or upon the sections 18 of the cross tracks. Each section 22 is connected by a conductor 24 with a source of supply and the base is grounded, as at 25. The third rails of the cross tracks are connected to one of the sections 22 by the conductor 26.

A pair of levers 27 is pivoted at the center of the base underneath the same and each end of each lever is connected by a link 28 with a switch member 11, each lever being connected with a switch member of the two tracks so that the switch members at both ends of a cross track will be operated when the lever is moved.

A pair of disks 29 is provided for operating the switch members, each disk being pivoted in an extension 1 of the base and being manipulated by a handle 30 and an eccentric pin 31 on each disk is connected with a switch member nearest to the disk by a link 32. Thus when the disk is given a rotary movement by its handle, one of the levers will be moved to move the two switch members with which it is connected.

Each lever has pivoted thereto a link 33 which has a slot 34 therein for engaging a pin 35 carried by the other lever so that when one lever has been moved to open a switch,

the other lever is locked against movement so that the second switch cannot be opened.

At each crossing of each cross track with the other track and where one rail of each cross track crosses a railof each main track, I provide spring frogs 36, each of which consists of a plate 37 having'its ends sloping downwardly and outwardly and supported on a spring plunger 38 so that when a wheel strikes the-plate, it will yield downwardly and thus take the shockand ease the crossing of thewheel overthe gap between two rails and prevent noise.

I also provide means for deenergizing a section of each main track at a distancefrom the switch, each of these sections having its third rail section 39 insulated from the rest of the third rail and each section 39 is connected by a conductor 40 with a contact 41 insulated from the under side of the base and adapted to be engaged by a contact 42 insulated from a lever 27 and each contact 42 is connected by a conductor 43 with a conductor 26. Thus when the switch members of one crossing are set to direct a. train from one track to the other, two of the third rail sections 39 will be deenergized so that a train cannot enter the switch section of a track to interfere with the passage of the other train through the open switch.

I also. provide signal lamps 44 and 45, the lamp 44 being green and the lamp 45 red, for signalling trains approaching each switch system from either direction on its track. Each lamp 44 is connected by a conductor 46 with a rail section 39, while each lamp 45 is connected by a conductor '47 with a contact 48 insulated from the under side of the base and adapted to be" engaged by a contact 42 on each lever 27 when the lever is moved from one position to another. These parts are so 4 arranged that a red lamp will be supplied with current when the switch members are in a position to permit a train to cross from one track to another so as to signal other The insulated sections of the third rails are bridged by the conductors 49 and these conductors may be supported in any desired manner, such as by being carried by portions of the third rails and insulated therefrom and provided with means whereby the ends of the conductors can be easily and quickly attached to the live portions of the third rail when the track sections are connected together.

From the above it will be seen that I have provided a switch system, the major portions of the main tracks and the cross tracks of which are stationary, the only movable portions being the switch members F, with means for deenergizing portions of the third rails when a switch is opened to prevent other trains from interfering with the train which is to take the switch and with means for signalling when the tracks are clear and when the switches are open.

It is thought from the foregoing description that the 'advantages and novel features of myinvention will be readily apparent.
