TOY RAILROAD-TRACK SWITCH.

Application filed March 16, 1927. Serial No. 175,689.

The present invention relates to toy railroad track switches and is more particularly directed to a track switch for use on toy electric railroads.

The present invention conten'iplates a track switch wherein a short movable switch tongue having two short sections of wheel bearing rail is provided, and so arranged as to guide the wheels of a toy train either through the main line of the switch or on to the branch line.

According to the present invention short converging wheel bearing rails are so arranged that one or the other may receive the car wheels on one side of the train after the Wheels pass 011' the guiding rails on the switch tongue and carry these wheels over to diverging rails which carry these wheels on through the main line or branch line as the case may be.

The track switch contemplated by the present invention has an electrically continuous power supply rail arranged between the wheel bearing rails for supplying power to both the main line and the branch line.

Portions of this power supply rail are depressed below the stationary converging portions of the wheel bearing rails above reterred to.

The fixed and movable parts of the switch are preferably carried on a frame, and the structure is so made that the switch forms a special track section which may be interchangeably used with other sections of the toy railroad track. The track switch may be combined with a signal and operated manually or electrically as desired.

The accompanying drawings show, for

. puroses of illustrating the invention, one of the many posssible embodiments in which the invention may take form, it being understood that the drawings are illustrative of the invention rather than limiting the same.

In these drawings:

Figure 1 is a plan View of a toy railroad track, embodying the present invention; and Figure 2 is a sectional view taken on the line 2-2 of Figure 1. As shown in the drawings, the track switch is made up in the form of an interchangeable section of a main line designated by the letter A and a branch line designated by the letter B. The main line A has a straight outside track or wheel bearing rail 10 extending through the length of the track switch, while the branch line B has a curved outside track rail 11 which extends from the lower end of the switch section, as indicated in the drawing, out through the branch line. The main and branch lines also have wheel bearing rails 12 and 13 which diverge from a frog 14. A Y- shaped power supply or third rail extends through the switch section. As here shown, the lower end- 15 of the power supply rail is placed between the track or wheel bearing rails 1Q and 11, while the

upper branches

16 and 17 of the power supply rail are placed between the wheel bearing rails 10 and 12 and the wheel bearing rails 13 and 11, respectively. A member 18 is provided which connects the portion 15 with the

portions

16 and 17 of the power supply rail. This member 18 is comparatively broad, as indicated at 19, and has a depressed portion 20 which is connected to the lower ends of the

center rails

16 and 17.

The wheel bearing rails 10, 11, 12 and 13. and the power supply rail are mounted in any convenient manner on a sheet metal frame 21, the power supply rail being insulated by insulators 22. The frame may be skeletonized, if desired, by punching holes a, I), c, d and 6, thereby having cross

members

23, 24, 25, 26, 27 and 28. The depressed portion 20 of the power rail extends down into the opening 0 in the frame.

A short length of wheel bearing rail 29 is suitably mounted on cross members 25 and 26 of the supporting frame in line with the wheel bearing rail 12 while another short length of wheel bearing rail 30 is similarly mounted so as to be in line with the wheel bearing rail 13. These two wheel bearing

rails

29 and 30 cross over the opening 0 in the track frame and converge toward the frog 14. But their upper ends. as indicated in the drawing, do not reach this frog, room being provided to permit the flange of the car wheel to pass from one rail to the next. These converging rail sections are supported some distance above the depressed portion 20 of the power supply rail, this being more clearly brought out in Fig. 2.

In order to guide the toy train through the main line or the branch line of the track switch, there is providt'l a movable switch tongue 31 pivoted at 32 on the cross member 26, and provided with converging guiding rails 33 and 34. This movable switch tongue is supported by the cross member 26 and operated in any desired manner such as by the link 35 connected to a hand lever 36 supported on the frame and associated with a signal 37 if desired.

When the switch is in the position shown in full lines and the movable wheel guiding rail 34 is arranged to intercept the flange of the car wheel and carry the car straight through the main line, the wheels passlng over the wheel bearing rails 34 and 30 onto the wheel bearing rail 12 and the car continues on through the main line track. When the movable switch tongue is shifted to the dotted line position, the rail 33 intercepts the flange of the car wheel and carries this wheel over the

rails

33 and 29 onto the rail 13 in the branch line.

Track switches, made in accordance with the present invention, and provided with the short stationary lengths of

wheel guiding rails

29 and 30 and with the short movable switch tongue such as indicated at 31 may be manipulated very easily. There is less mass in the moving parts and there are fewer bearing surfaces for supporting the rails than formerly employed in toy track switches having long switch tongues. While the present drawings show the switch tongue manually operated, it will of course be understood that the switch tongue may be operated electromagnetically, for example, by a construction such as shown in Patent Number 1,548,940, (granted on m application Serial Number 574,212, file July 11, 1922. By dividing the tracks above set forth, and making it unnecessary to move a heavy switch tongue, it is possible to obtain improved operation of the track'switch by electromagnetic devices, such as shown in the patent above referred to.

It is obvious that the invention ma be embodied in many forms and constructions, and I wish it to be understood that the particular form shown is but one of the many forms. Various modifications and changes being possible, I do not limit myself in any way with respect thereto.
