(Cl. 23S-40) 8 Claims. l

This invention relates to an improvement in the type of toy railroad track disclosed in my Patent 2,120,250, issued June 14, 1938, for Toy Railroad Track.

The principal objects of this invention are:

First, to provide a continuous solid nexible center rail which will assure uniform tie spacing and smooth regular curves in a toy railroad track.

Second, to provide a toy railroad track which will have improved rigidity and self-supporting properties and eliminate sharp and irregular bends in either horizontal or vertical directions.

Third, to provide a toy railroad track having improved electrical conducting properties and which will reduce the amount of wear on the contact shoe of toy locomotives.

Fourth, to provide a toy railroad track having improved durability and less tendency to become loose and rough with prolonged use.

Fifth, to provide a novel form of joint for sections of toy railroad track and means for attaching electrical supply lines to any joint of the track.

Other objects and advantages relating to details of my invention will be apparent from a consideration of the following description and claims.

The drawings, of which there are two sheets, illustrate a preferred form of the improved track.

Fig. l is a plan View of a section of the improved track with the clip for attaching electrical supply wires attached to one end of the section.

Fig. 2 is a fragmentary enlarged side elevational View of one end of the track section with the joint section and electrical attaching clip mounted thereon.

Fig. 3 is a transverse cross sectional view through the track section taken along the plane of the line 3 3 in Fig. 1.

Fig. 4 is a side elevational view `of one of the rail connectors used to connect sections of the track.`

Fig. 5 is a fragmentary longitudinal cross sec tional view through the joint between two sections of the track and taken along the plane of the line 5-5 in Fig. '7.

Fig. 6 is a fragmentary longitudinal cross sectional view through the center rail.

Fig. 7 is a transverse cross sectional view through one of the joint sections of the track and taken along the plane of the line '1 -'I in Figs. l and 5.

Fig. 8 is a fragmentary bottom plan View of one of the side rails with the ties removed.

The track consists of a series of wooden ties I which support side rails 2 and the center or third rail 3. The track is made up in sections of any desirable length and is provided with a male joint section 4 and a female joint section 5 at each end of the track section. The side rails 2 consist of a plurality of telescopically interlocking rail sections 6 which are the same as those illustrated in my patent mentioned above. Each rail section is secured to an elevated block I on the top of a tie I by pressing the sides of the rail section into the sides of the elevation as at 3, see Figs. 2 and 3. Each rail section 6 includes a large end 9 of U-shaped cross section and a small end l@ also of U-section arranged to telescopically nt within the large end of the next succeeding rail section. Both the large and small ends of the rail sections are outwardly anged as at I I, the flange on the small end being downwardly offset to lap underneath the ilange on the next succeeding rail section.

The ties l of the present track diner from the l es in my issued patent in that the elevated block I2 for supporting the center rail is substantially `higher than the elevated blocks 'I for engaging the side rails. The top of each center block defines a vertical bore I 3 arranged to receive a pin I 4 projecting downwardly from. the under side of the center rail 3.

The center rail 3 is formed as a continuous strap of metal, preferably springable steel, and the pins I 4 are integrally attached to the under side of the rail. I have found that the center rail is most economically formed by stamping the rail 3 and the pins M from a continuous flat strip of metal stock. The upper surface oi the rail 3 is rounded so that the center rail approaches a circular cross section but is in fact a nat strip `with the pins i4 projecting from the lower edge thereof. The holes I3 and pins llt are of such realtive size that the pins rmly engage the blocks I2 to permanently connect the center rail and the ties.

The female joint section at one end of the track section consists of a sheet metal stamping of U-shaped cross section having the ilanges I5 thereof extending transversely of the track section. The web of the joint section '.i has four ears I6 struck upwardly therefrom and adapted to be bent over the edges of the ilang'es on the two rail sections on the end of each side rail. The outer flanges of the end rail sections are thus securely clamped to the joint section 5. The

inner flanges of the end rail sections are secured to the joint section by a plate Il of librous insulating material which is secured to the web of the joint section by rivets I8.

The end of the center rail 3 is permanently received in a socket member Iii consisting of a U-shaped metal stamping having laterally extending flanges on each side thereof. The flanges-20 rest upon a sheet of insulating fiber 2| which spaces the socket member from the joint section 5 and which is held in place by the rivets I8. It will be noted that the upper insulating plate il is slotted from the end of the track section as at 22 to permit the upper portion of the socket I9 to project upwardly therethrough. It will further be noted that the side rail sections Ba on the end of the female joint section are of uniform cross section and are not provided with reduced end sections Iii as in intermediate portions of the track.

The male joint section 4 at the opposite end of each track section is substantially identical to the female joint section. with the exception that the web of the joint section Li is downwardly offset in the center as at 23, (see Fig. 7) to receive the rivet 24 for pivotally receiving the latch arm 25. The arm 25 extends from the end of the track section and is provided with an upturned outer end 2S arranged to fit within and engage the end flange I5 on a female joint section 5, as illustrated in Fig. 5. It will be noted that the end flanges of the joint sections i and 5. are notched in the center as at 2 so that the latch arm 25 can extend therethrough without interfering with the fiat engagement between the bottoms of the joint sections and the floor on which the track is supported. In commercial practice it is advisable to make each of the stampings which form the joint sections i and 5 of identical construction so that the joint sections differ only in that the female joint section is not provided with the latch arm 25 and rivet 24.

The rails of adjacent track sections are connected by connectors 28 which consist of folded wire elements shaped'to prov-ide longitudinally extending end folds 29 and depending prongs 33. The bight of the wire element between the legs 29 is upwardly offset as at 3l so that it will be substantially flush with the connected rail sections when the arms 29 are received telescopically within the connected rail sections. It will be noted that the large end 6 and 6a of the rail sections at each end of the track section telescopically receive the arms 29 and that the U- shaped cross section of the rail sections require that the legs Si) be positioned in a downwardly extending position to provide an operative track surface.

The clip for connecting the power source to the track is most clearly illustrated in Figs. l and 2 and consist of a pair of straps 32 secured together by the rivets 33 but insulated from each other by the strip of insulating material 31?.. The ends of the straps 32 are provided with longitudinally extending terminal flanges 35 which carry terminal bolts for attaching power wires to the clip. The center portion of one of the straps `32 is notched and the other strap is longitudinally offset into the notch as at 3l. lThe depending legs on the connector 29a are lapped upon the sides of the ofset and soldered thereto so that the connector electrically connects the strap to the center rails of two adjacent track sections. The depending legs 3d on the connectors 29h between the side rails are soldered to electrical connections to the side rails and to the center rail.

In order to assure continuous electrical contact between the side rail sections 6, I have provided a conductor strand 38 which is bent into horizontal zigzag shape as illustrated in Fig. 8 and which fits Within the U-shaped cross section of each side rail. As described inV my patent referred to above, the conductors 38 will expand or contract by flexing of their zigzag shape as the tie section is bent to form a curve as indicated by the dotted lines in Fig. 1.

rThe continuous flexible center rail 3 provides a smooth wearing surface for the Contact shoe of toy locomotives and also provides a continuous springable connection between all of the ties I in a track section so that transverse bending of the track section occurs along a uniform curve and eliminates any tendency of the bending to be localized between ani,1 one rail section which may become loose with respect to other connections in the track section. The continuous center rail 3 also has a definite bridging effect to carry the track section across unsupported sections and to assure smooth vertical curves in the track section as it is extended over irregular supports such as the edges ofV rugs and bridge approaches. The continuous center rail also forms a more positive continuous electrical connection for the track than the sectional center rail illustrated in my patent. Within the elastic limits oi the center rail 3, the track section can be made to assume smooth uniform horizontal and vertical curves or straight sections depending upon the desires of the person setting up the track and the track section will return to its original straight condition when released from adjacent track sections.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent is:`
