A. FROHNE. CROSSOVER FOR 4TOY RAILWAYS. APPLICATION FILI-:o IIAYaI, I92I n siti .ALBIN EROI-INE, OF CHICAGO, ILLINOIS,

- CROSSOVER FOR igflgililg.

Application filed May 31,

To all whom# may concern Be it known that I, ALBIN F ROHNE, a citizen of Germany, having declared my intention of becoming a citizen of the United States, and residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Crossovers for Toy Railways, of which the following is a specification.

The present invention has to do with certain improvementsV in cross-overs for toy railways and the` like. lt has particular reference to cross-overs intended for use in toy third rail railroads.

One of the objects of the invention is to provide a cross-over of such construction that the trolley contactors on the electric cars will not become grounded as they pass over the cross-over, thus preventing the es tablishments of short circuits.

Another object of the invention is to provide a very simple construction of cross-over and one which can be very cheaply manufactured and which will be very durable.

Another object of the invention is to so construct the cross-over that current will be delivered to the trolley contactor in a practically continuous manner as the cars travel over 4the cross-over.

Still another object is to provide a crossover of such construction that the cars will run over it in a relatively smooth and. easy manner, thus largely eliminating the jarring ordinarily attendant upon the passage over the cross-over.

Other objectsvand uses of the invention will appear from a detailed description of the same, which consists in the features of construction and combinations of parts here'- inafterdescribed and claimed.

Referring to the drawing:

Figure 1 shows a plan view of a 60O 'crossover embodying the features of the present invention;

Fig. 2 shows a bottom View corresponding to Fig. l; and

Fig. 3 shows a vertical cross section taken on the line 3 3 of Fig. 1, looking in the direction of the arrows.

e cross-over herein illustrated is designed to cross the tracks 4 and 5 which lie at an angle of substantially to each other; but vit will be understood that the features of the invention are not limited toI a 60 cross-over or a cross-over of any other l ASSIGNOR T0 AMERICAN FLYER TUBING CO., OF CHICAGO, ILLINOIS, A CORPORATION OF ILLINOIS.

particular angle. The track 4 includes the rails 6 and 7, and the track 5 includes the rails 8 and 9. The track 4 also includes the intermediate third rail 10, and the track 5 also includes the intermediate third rail 11.

he end portions of the rails 6, 7, 8, and 9 rest upon and are supported by a base plate 12 comprising a sheet of metal having its edge portion turned down to provide the flanges 13 which also constitute a foundaion.

Qn the central portion of the base plate 12 is located a block 14 of insulating material, such as ber. .l lThis block preferably has its edge portions formed to lie in the same directions as the dierctions of the tracks; and in the construction illustrated, the block 14 is of diamond shape. Its top surface lies substantially at the saine elevation as the tops of the rails, and it is provided with the grooves 15 and 16 in alinement withl the inside faces of therails 6 'and flanges of the cars traveling over the vcrossover. The grooves are cut to the proper depth to bring their bottoms substantially at the correct elevation to support the lflanges of the wheels traveling through, so thatl the cars will pass over the cross-over withoutany jarring. Itv will be observed that the corners of the to'accommo'date the end portions ofthe rails, so that the grooves l5, 16, 17 and 18 extend back of the ends of the rails a sufficient distance to take the load of the flanges of the wheels before the wheels leave the rails proper.

As stated above, sulating blocklies substantially at the saine elevation as the top surfaces of the rails, so that the wheels said'top surface or'by having their flanges ride on the bottoms of the grooves.

The insulating block 14 may be held in place in any suitable-manner, 19 and 20 which extend through the base block -14 .are recessed the top `Surface of the intoV will be either supported by Y as by rivets plate l2. These rivets when used' should be the same elevation asthe venient manner as by to join together the sections of-third rail;

and another wire 25 maybe connected to oneof thethird rails or to onel of said wires and to the conducting section 21 so as to Supply current to the same.

The running rails 6,7, 8 and 9 may be fastened-.to the base plate 12 -in any conmeans of the clips 26; and the third rails 10 and 11 may be 'of my present invention,

secured tothe base platein any convenient manner "as by the cli s 27 with the interosed sections of insu ating material 28. `While I have herein shown and described only asingle lembodimentof the features still I do not limit myself to the same except as I may do in the claims.
