5 Claims.

This invention relates to track systems for toy trains and more particularly relates to novel flexible tracks adapted to be arranged in a multiplicity of configurations. This case is a continuation in part of my prior application, Serial No. 187,790, flled January 31, 1938, entitled Toy train system." 7

The general track arrangement for prior art toy train systems consisted of segmented tracks 10 of predetermined length and shape. The track segments were rigidly constructed and adapted to be joined end to end to form the track system for the train. The number of shapes into which such tracks could be formed was naturally lim- 15 ited due to the rigid construction of the track segments. Accordingly, after the system \was used several times, the child became tired ofit due to the repetitious paths and similar appearance of its operation, In accordance with my present invention, I contemplate providing flexible track systems for toy trains which the child may arrange into any number of shapes or forms. These tracks may be employed with either electrically or mechan- 25 ically driven toy trains. The construction of my novel tracks readily permits bending thereof without mechanical weakening.

The flexible tracks of my present invention are provided in long lengths or rolls together with so appropriate track spacing members. The child accordingly may construct his own railway system using spacers corresponding to regular railway ties. The track system can be made in any length desired, and formed into any complex shape or curvature. The non-rigid construction of the track system for the toy trains provides means for developing the ingenuity of the child and results in a longer period of continued interest as compared to systems of the prior art. 40 The preferred form of my novel track is a wire ribbon, the longitudinal central portion of which contains a multiplicity of parallel transverse slots, bent around a flexible wire. The portion of the ribbon bent around the wire forms a beaded section constituting the rail proper. The remainder of the track ribbon constitutesthe supporting structure for the track. The continuous flexible track is severable into any desirable length in a manner to be hereinafter described in detail to form cooperating track segments. The severed track segments cooperate with other track segments for joining into a continuous operable railway track system. 55 g It is accordingly an object of my present invention to provide novel flexible track constructions for toy train systems.

Another object of my present invention is to provide a toy train track system adapted to be arrangedinto a multiplicity of configurations. 5

A further object of my present invention is to provide a continuous flexible track section readily adapted to be severed into small sections for forming flexible track segments.

These and further objects of my present in- 10 vention will become apparent in the following description of my invention taken in connection with the drawings in which:

In Figure 1 I have illustrated a typical multicurve track system into which the flexible track sections of my present invention can be formed. The flexible track system is composed of individual tracksections 20, 2|, 22, 23, 24, 25 and 26, 5|

lying between the broken lines s--s drawn transversely of the tracks on the flgure. The ends of adjacent track sections are mechanically and electrically joined along the positions s-s in a manner to be hereinafter described. The individual track sections comprise track segments 30 and track spacer or tie members 3|. Ties 3| rigidly hold the track segments 30 in predetermined laterally spaced relationship corresponding to the spacing between the wheels and the third rail contact member of the train. A train T is indicated in dotted in position upon the track system.

Figure 2 is an enlarged perspective view of a track section such as used to build up the flexible track system. The track section comprises track segments 30 positioned upon'spacers or tie members 3|. The track segments consist of a serrated beaded section 32 enclosing a wire core 33. The wire 33 projects from one end of each track segment, from the right end in Figure 2. A portion of the wire at the opposite end 34, the left end of the segment, is removed in a manner to be described, to constitute the female joint in the track assembly,

Figure 3 is a plan view of two separated track sections 35 and 36. The right ends of the sections 35 and 36 contain projecting wire sections 33 constituting the male joining members of the assembly. The left ends 34 of the track sections contain holes in the beaded portions of the track sections 30 to engage with the projecting wire sections 33.

Figure 4 is a perspective illustration of two single track segments 30 and 30 mechanically and electrically interconnected. The projecting portion 33 of segment 30 sets into the female end 34' of segment 30'. Joint 31 between track segments 30 and 30' constitutes a mechanical as well as electrical interconnection of the two segments for forming the continuous track system.

The track segments are formed from a continuous roll of track supplied with the train outfit. Figure 6 is a perspective illustration of a portion of the roll of the track 40 as supplied. The track, being flexible, is unwound from the roll and straightened. A desirable length of track segment is clipped off by a pair of pliers. In forming a curved track section such as illustrated in Figure 2, different lengths of individual track segments are required. The outer segment of the curved track is greater in length than the inner one. Accordingly, the mechanical skill of the child is brought into play in properly designing and constructing the track sections. The preferred procedure is to insert the middle track segment 30a to determine the mean or average length of the track section and the mean curvature thereof. The inner and outer track segments are proportioned to the medial one 300. as to shape and length required.

In clipping oil? the track length from roll 40, it is necessary to automatically form the male and female joints of the individual segments.

An important feature of the flexible track system of my present invention resides in the simple manner in which the joined members are formed. The end partially broken-away view and constructing the track segments is as follows:

With an ordinary cutting pliers or shears, sever the metal body portion 42 transversely of the track in the region indicated by the arrow a. Region 0. is chosen to intersect a slotted region in the beaded portion of the track. Slotted region 43 was here chosen. Another cut is required for completing the severance of the track section 4|. The wire core of section 4| is severed from the continuous wire core 44 of the continuous track roll 40. A substantial projecting portion of wire core 45 remains with the track 4| to constitute the male joining portion thereof. To provide for this joint, wire 45 is cut away from the main wire 44 at an intermediate portion in the ribbon constituting the track 40; By cutting wire 44 between the slotted position 46 at the ribbon indicated by the arrow b, a substantial male joining section at 45 is insured for track 4|.

The length of the projecting wire portion 45 should preferably be predetermined and standard for the whole track system. The length is readily determined by counting the number of slotted elements 41 from the region of severance a to determine the cutting region b. In the illustrated track, two slotted elements 41 are used to determine the length of the joint for the track segments. Since relatively soft, malleable or bendable metal is used for the body of the tracks 42 and the wire core 44, sharp, clean cuts along a and b regions are readily made with an ordinary metal severing tool. The cuts on successiv regions corresponding to a on track roll 40 determines the length of the individual track segments. The lengths of the segments are optional but are chosen for the proper design of the track structure and to compensate for differential lengths constituting a curved track section. The distance between the region of severance a and the wire cutting ribbon b deter mines the length of the electrical-mechanical joint between the track sections. In cutting the wire 44 at b, the male joint members for the severed track segment are determined as well as the female joint for the next segment to be formed. The forming of the track segments from th flexible track roll is a simple procedure which the average child can readily learn.

One form for constructing the track members is illustrated in Figures 7 and 8. A metallic ribbon 50 is used. Ribbon 50 contains a plurality of equispaced transverse slots 5|. Figure 8 shows the flexible metal wire 52 which is placed centrally of the ribbon 50 before bending thereof. The spaced slotted elements 53 result from the transverse slots 5| in metal strip 50.

The wire core 52 is placed centrally of the metal ribbon 50. Metal strip 50 is then bent around the wire and pressed into the shape to form the track member as shown in perspective in Figure 4. The outer ends 54 of the strip are pressed together to form the supporting body portion of the track. The slotted elements 53 constitute the beaded section of the track upon which the train rides.

Electrical contact is made to the tracks in any preferred manner for-in turn communicating a proper electrical circuital relationship with the train supported and guided thereon. Three track segments have been illustrated as forming the individual track sections. However, a different number may be so used. The all metal feature of my tracks makes the problem of electrical concurved form while substantially retaining the proper shape and mechanical rigidity for the track sufllcient for supporting and guiding the train.

Figures 9, 10 and 11 are perspective illustrations of track tie members used'for building up the track sections from-the individually cut and formed track segments. Figure 9 ls the.

simplest form and comprises a rectangular block 8| containing transverseslots Ila for containing the body portions of the track segments. Figure 2 illustrates the coaction of the flexible track segments 88 with the blocks 8| as shown in Figure 9. The tracks are thus maintained in proper spaced relationship corresponding to the design of the train. In Figure 10, a cylindrical tie member 88 is illustrated containing threaded end portions 88 and a central slotted portion 51. Figure 11 illustrates a further tie form com-' prising a rectangular block 88 and spring clip members 88 for gripping the body portions of the track segments as will now be evident.

In Figure 12 I have illustrated an assembly for employing the cylindrical tie members 88 as track supporting ties. In this type of tie, the central or third rail" 88 is in a higher position than the end rails 8| and 82. Thus the power collecting shoe in the train is necessarily positioned a little higher than in the track system illustrated in Figure 2. The end track section 8| and 82 contain spaced holes in the body portions Ola and 82a thereof to accommodate screw members 83 which are screwed into threaded ends 88 of tie 55. Brackets 84 are included between the screw 83 and the tie 55 for fastening the track assembly to a baseboard or merely resting it on the floor as desired. Figure 13 is an end view of the tie 58 shown in Figure 11 containing the track segments 85 to constitute the track section. Tracks 85 are held in position by the spring clips 58. Screw members 88 hold clips 88 in position on block 58. Electrical connection to the tracks may be made through the screw members 88 in the tie 58 or in any other suitable manner.

A modified track arrangement is illustrated in Figures 14 and 15. Figure 14 is a perspective illustration of track segments 18 containing beaded sections II and wire cores I2. The body section 13 of the track 18 is a single metal layer in place of the double layer of the previous modifividually spaced elements gripping a wire core 12. The spaced elements permit twisting or bending of the track in any desired shape in a manner hereinabove described. After bending the track will retain the bent form. The rigidity of the track is unimpaired and may be used to support the regular toy train systems.

Figure 16 is a perspective illustration of a secable means 82 such as rivets or, if metal to metal, by spot welding. A reinforcing wire 84 is secured above edge 88 of strip 88 by the clamping members 8| in a manner similar to the track arrangements hereinabove described.

The clamping elements 8| are of a thin material such as .010 inch. For a conductive track; both the wire 84 and the clamping elements 8| are of conductive material. The intimate contact of wire. 84 with elements 8| establishes a continuous electrical arrangement across the top or bearing surface of the track. One end 86 of wire 88 projects beyond the track section to constitute the male Joint connection of the track. At the other end, one or more clamping elements 8| are hollow, namely do not contain a reinforcing wire,

in order to constitute the female connection joint for the track segment.

The spacing between the clamping segments 8| is preferably less than the width of the elements 8| as taken in the longitudinal direction of the track. Such close spacing of the segments is preferable to avoid a bumpy riding of the train on the track. The closer'the spacing of thevelements 8|, the smoother the ride on the track. However, too close a spacing is to be avoided. Thus, a spacing between elements 8| should be at least equal to the thickness of the element 8| to permit the flexing or bending of the completed track section without interference by the adjacent clamping elements. This spacing design feature also is applicable to the previously described track modifications.
