21 Claims.

This invention relates to toy railroad tracks, and more particularly to those which are flexible and extensible, in order that the track may be used in difierent places, and in different shapes.

Generally stated, the object of the invention is to provide a novel and improved construction and arrangement whereby a track of this kind is composed of sheet metal sections flexibly telescoped together and secured to ties or sleepers, preferably of wood, without the use of nails or screws orother fastening devices, whereby the track may be straight or curved, when in use, and may be rolled up into a compact and neat bundle or package for shipment or storage.

It is also an object to provide certain details and features of construction, and certain combinations, tending to increase the general eificiency and the desirability of a flexible and extensible toy railroad track of this particular character.

To the foregoing and other useful ends, the invention consists in matters hereinafter set forth and claimed and shown in the accompanying drawings, in which- Fig. 1 is a perspective of a section of track embodying the principles of the invention, showing the same laid down straight.

Fig.2 is a plan view of a section of said track, showing the same laid down on a curve.

Fig. 3 is a plan view of a section of the track with its ends brought together, providing an endless track for the toy cars.

Fig. 4 is an edge view of a section of the track,

showing the same rolled into a bundle or package for shipment or storage.

Fig. 5 is an edge view or side elevation of a section of the track, showing the same flexed to extend over a simulated hill or grade.

Fig. 6 is a perspective of one of the short telescoping sections of the track, which are made of sheet metal. a

Fig. 7 is a perspective of portions of two adjacent sheet metal sections, showing the manner in which the same are telescoped together.

Fig. 8 is a plan view of three of theties or sleepers, preferably of wood, with their respective sheet metal sections secured thereto and telescoped together, and with the ties or sleepers shown as converging to illustrate how the'track is flexible laterally to provide a right or left curve.

Fig. 9 is a view, on a smaller scale, of three ties or sleepers, with the sheet metal sectionssecured thereto, arranged in separate form, and illustrating certain details of the construction.

Fig. 10 is a perspective of one of the wood ties or sleepers that are preferably used in the construction of the track.

Fig. 11 is a perspective of one of the sheet metal sections that are used at one end of a length of the track.

Fig. 12 is an enlarged longitudinal section of a length or section of said track.

Fig. 13 is an enlarged transverse section on line l3l3 in Fig. 12.

Fig. 14 is a bottom view of the structure shown in Fig. 12, with the ties or sleepers shown in dotted lines, being in effect a section on line l4--I4 in Fig. 12 of the drawings.

Fig. 15 is an enlarged transverse section on line l5-l 5 in Fig. 12 of the drawings.

Fig. 16 is a view similar to Fig. 12, but showing the telescoping sheet metal sections somewhat extended to illustrate the flexibility of the track.-

Fig. 1'7 is a similar view, but showing the track curved in the opposite direction.

, As thus illustrated, the invention comprises the ties or sleepers l, and to these are secured the sheet metal sections 2, which latter are of the kind shown in Figs. 6 and 7 of the drawings. It will be seen that each tie or sleeper is provided with three elevations 3, and with grooves 4 at opposite sides of said elevations, as shown in Fig. 10 of the drawings. It is to these elevations 3 that the sheet metal sections are secured, as shown in Fig. 15 of the drawings, by pressing the metal into said elevations 3, as shown at 5, whereby the sheet metal sections are secured to the ties or sleepers without the use of nails or screws or other fastening devices.

Each sheet metal section is formed, as shown in Figs. 6 and '7 of the drawings, with smaller end portions 6 that telescope within the larger end portions 1 .of the next section, as shown in Figs. 12, 16 and 17 of the drawings, and with this formationthe top of each track is practically straight and level, the offset at 8 of each sheet metal section beingsubstantially equal to the thicknessof the metal. :.The smaller end portion of each section has the depressed flanges 9, and the larger portion 2 ofeach section has the integral'fia'nges .l0, which are just the thicknessof the metal above the flanges 9, so that the latter extend, under the flanges ID of the next section, as shown in Fig. '7 of the drawings. 'I'he larger end of each section is provided with bendable portions II, which are inserted through the slots l2 with which each section is formed, and which are bent upwardly inside, "as shown in Figs; '7

and'13 of th'e drawings. It will be seen thatfth'e slots it are longer than the portions I I, so that there is some telescoping or endwise motion as between the sections, in order to provide the flexibility necessary for the desired method of using the track, as illustrated in Figs. 16 and 1'7 of the drawings.

At one end of a length of track thus constructed, there is preferably a block l3, forming two of the ties or sleepers, and the three sectional rails at this end of thelength are provided with plugs it for insertion into the sockets l5, which are provided on the ends of the three rails at the other end of the length of track, whereby to provide an endless or continuous track, when desired, as shown in Fig. 3 of the drawings.

The block also is provided with metal sockets I6, at one side of the track structure, to receive electrical conductor plugs IT, as shown in Fig. 9 of the drawings. Copper wires l8 are threaded through the hollow sheet metal sectional tracks thus formed, resting on top of the elevations 3, and these wires are preferably formed with lateral bends, so that each wire is practically zigzag in effect, providing portions which make electrical contact with the sheet metal sections of the tracks, and these three copper wires I8 are suitably connected, as shown in Fig. 9 of the drawings, with the sockets l6, whereby electric current may be supplied to the three rails of the track to drive the electric locomotive of the toy railroad. If desired, the middle rail may have two copper wires l8, to more certainly provide electrical contact with all of the sheet metal sections of this middle rail, the latter being the one to which the current is taken into the track, and the two outside rails being the ones that return the current to the source. Of course, the electrical connections may be of any known suitable or approved character, so far as the sheet metal construction of the track is concerned, but the wiring shown and described is effective for the purpose of electrifying the three rails of the track, thereby to drive the toy cars in the desired manner.

Thus, the track can be made in lengths, either short or long, and the lengths can be telescoped together, by using the plugs i4 and the sockets l5, previously described. The track is flexible laterally, as shown in Figs. 2 and 3 of the drawings, and as illustrated in Fig, 8 of the drawings, to provide a right or left curve for the track. It is also flexible up and down, as shown in Figs. 16 and 17, to simulate hills or grades for the track. When not in use, the track can be rolled up in a neat package or bundle, as shown in Fig. 4 of the drawings, and this also facilitates the shipping and selling of the track, as even a long length of track can be rolled up neatly and compactly in a comparatively small box or package.

Furthermore, the track is comparatively inexpensive to make, as the fastening of the sheet metal telescoping sections to the wood ties or sleepers is accomplished without theuse of nails, tacks, screws or other fastening devices. With proper machinery, the toy track construction shown and described, can be turned out endlessly, practically, and then cut or severed into lengths of the proper or desired dimensions.

From the foregoing, it will be seen that the sheet metal rail sections are rigidly secured to the ties or sleepers, and are formed in such manner that they directly engage each other at their ends, preferably by telescoping their ends together, thereby practically providing a continuous rail, a rail of practically continuous continuity, along the tread thereof, when the sections are relatively adjusted endwise, for either extension or contraction of the rail, as in providing a curve or bend in the track.

What I claim as my invention is:
