ltrack or ontoY a branch line track, at will. Such switches are, for convenience, made up in the form of a section of track interchangeable lwith other sections of track. The wheel bearing rails in such a switch section include a straight uninterrupted length of track rail at one side for the main line track, a curved uninterrupted length of l track rail at the other side for the branch line track, '.short converging lengthsl of track arranged -in the form cfa V par-y hs and connectedallel withv the longer len to the correspondlng trac rails in adjacent sections of main line track vand branch line track, respectivel and also an'arrangement of converging rails by which the car trucks may beguided at will to the main line track or the branch line track. /Where these switch sections are employed in electric toy railly continuous insulated third rail is arranged intermediate the wheel bearing rails so that the contact shoe in the traln may engage it. This power supply rail includes an ordinary narrow third rail between the pairs of track rails above referred to, al' wide portionbetween the guidl' ing rails, and Y-shaped depressed portion arranged underneath the wheel bearing rails for interconnecting the wide portion and the narrow portions, and carrymg the current through the switch section out of contact with the grounded Vtrack rails. The depressed portion was made as short as possiblel to eliminatethe ossibility of thelocomotive stoppin 'witlii its contact shoes out 'of contact wit the ower rail, which results in bring-` ing' the ivef rail close to the converging guiding rails. This close spacingof these parte frequently resulted -in the contact shoe ridging the p between the insulatedparts and ground arts.y f The principa object of the present invention is to insulate the portions of the guiding rails ofthe switch Vwhich are adjacent the insulated power railso that these poreontact with the contact shoe.

Ytions cannot become grounded'by accidental switch tongues and the third rail.

Referring in detail to the drawing, 10 indicates the main railroad track of a toy electrical railroadand 15 a branch line thereof. The track 10 comprises the rails 11, 11 extending over crossfties- 12 and an intermediate third rail 13 insulated as at 14 from the said ties. Preferably the rails and cross# ties are made in one piece from sheet metal, the cross tiesbeing in the form of bases or standards depending downwardly from the rails and serving as supports whereby the railroad rests on the iloor of the room.

Figure 5 is afperspective view of one of.

The branch line 15v comprises similar rails 16` 16 extending across similarly constructed cross-ties 17 and an intermediate track rail 18 insulated from the cross ties as at 19.

Where the branch line 15 connects with the main track 10, tlie respectivethird rails 18, 18ers connected yby a fcrkA member 20 from which extends a widened portion 20* so that the train contact shoe (not shown) may stay in contact with the third railv from the main track to the branch track and vice versa in the manner` hereinafter described. The switch tongues 21, 22 are preferably integrally formed from sheet metal and comprise hollow rail sections ofy similar construction to the rails 11. 11 and 16, 16 struck up so as to up:tand from the base 23. The swltch tongue members converge towards each other at the portions` adjacent the cross over in the usual manner.

The fork 20 is disposed between the two cross-ties 12", 12,.-adjacent thetrack junction, and is depressed below the said tongues. For joining the fork 2O to the widened portion 20, the material of the former is struck up adjacent the portion 2Oll und extends upwardly through the o ening 23c provided in thek tongue base 23. pivot pin 24 extends through the base'23 and the, cross tie 12, and another ivot pin or screw 25 extends through the ase portion 23 into a slot 26 formed in the switch lever 27, eccentrically mounted on the bottom of the platform or support 26 extending from the tracks, a curved slot 30 being provided yin the platform wherein rides the pin 31 extending from the remote endfof the switch lever. Mounted on the to of the platform 26 is a hand lever 32 to w ich the switchl arm 27 is eccentricall linked by means of said pin 31.

The hand ever 32 yis further centrally pivoted to a vertical shaft 33 extending into the block signal tower 34 and carrying at its up r -end the block signal 35, so that' and lever 32 is actuated the switchv when lever 27 is' actuated so as to move the switch tongues in one direction or the other about the pivot 24, and at the same time the shaft 33 is rotated so as to set the block signal. In this way, simultaneously with the switching of the train from one track to the other, the block signal is 'correspondingly set.

From the position of the switching tongues shown in dotted lines in Figure 1, it is clear that as the train contact shoe` (not shown) leaves the third rail 13 at the end 13 adjacent the tongue 20, the said contact shoe may accidentally swing into the space 13b between the switchA ton ue 21 and the end 13 of the third rail, t us causing a short circuit. Aysimilar condition may arise between the tongue 22 and the third rail 18, and between either or both the tongues 22, 21 and the widened portions 20". To prevent such short circuits, II provide the' switch tongues 22, 21 along a substantial portion thereof with the insulators 36, 36', comprising stri s Aot `insulating material such as hard ru )ber that extend along the side of each rail section of the switch tongues which faces or is adjacent to a third rail. These strips are rigidly securedpby any suitable means to said'rail sections. In the form Ashown 1n the drawnlg, the respective sides 21, 22 of the switch tongues are cutaway as at 21", 22", and the insulating strips ex-v Vwhen the contact shoe accidentally or other# wise is moved out of its vertically suspended position.

When a train passing through the switch 'is routed to or from the branch line (the parts being as shown in full lines in the tend across said cutaway portions and into drawing), the contact shoes wipe along the third rail 18-20-18. They strike the top` of the insulators 36 of the wheel bearing rail in the switch tongue but do not ground Y the third rail. When the switch is in the other position the contact shoes pass over insulator 36' without grounding. In either case it is apparent that the portions of the wheel bearing rails, over which the con? tact shoes pass, are insulated.

It will thus be seen that there is provided a device in which the several objects of this invention are achieved and which is well adapted to meet the conditions of practical use.

As various possible embodiments might be made of the above invention, and as various changes might be made in the embodiment above setforth, it is to bev understood that all matter herein s et forth or shown in the accom anyin terpreted as i lustratlve and not in a limiting sense.
