10 Claims.

This invention relates to toy railroads, and more particularly to a connecter for providing detachable electrical connection with a toy rail road track.

The primary object of my invention is to generally improve track connecters or track clips. More particular objects reside in the provision of a track connecter which is simple and inexpen sive in construction; which will fit any section of the track; which will fit different makes of track of the same gauge regardless of the crosssectional shape or dimension of the rail or of the bottom flange thereof; which will be detachable and yet provide a secure grip on and connection to the track when attached; and which employs a construction scheme for attachment to each of the rails such that the connecter may be used for connection to one, two or three rails of the section, as may be desired.

To the accomplishment of the foregoing and other objects which will hereinafter appear, my invention consists in the connecter and track elements and their relation one to the other as are hereinafter more particularly described in the 25 specification and sought to be defined in the claims. The specification is accompanied by a drawing in which:

Fig. 1 is a plan view of a track section with a connecter embodying features of my invention;

Fig. 2 is a section taken in the plane of the line 2-2 of Fig. 1;

Fig. 3 is an inverted plan view of the connecter applied to the track;

Fig. 4 shows the connecter in perspective; and

Fig. 5 is a section taken in the plane of the line 55 of Fig. 4.

Referring to the drawing, I may preliminarily explain that a toy railroad track comes in sections, each including outer or wheel-carrying l4 held in spaced parallel relation by ties I 6. For electrical operation it is also customary to provide a center or third rail [8. The ties I6 may be formed of sheet metal plates, the side edges of which are bent downwardly to form .45 supporting flanges 20. The top of the tie is appropriately slit to form tongues or lugs 22 which are bent over the rail flanges to lock the rails in place. Center rail I8 is insulated from outer rails 12 and I 4 by strips of insulation 24 wrapped around the lower part of the rail and interposed between the rail and the tie.

The rails l2, l4, and i8 are formed of sheet metal strips which are rolled downwardly to form a head portion 26, then inwardly and downwardly to form web portions 28, and then outwardly to form the flange portions 30. It will be noted that there is a slit or fissure 32 between the sides of web portions 28, this resulting from the fact that the web is formed of a double thickness of sheet metal.

Connecters have heretofore been made with complicated hook or clip portions intended to encompass and engage the flanges of two of the track rails. The shape and construction of the ties and the cross-sectional shape of the rails differ in tracks made by difierent manufacturers, but the gauge has been standardized and in all cases the rails are made of sheet metal folded or rolled downwardly to form a double thickness web as heretofore described. The connecter of my invention takes advantage of this fact and is therefore applicable to tracks of differing manufacture.

Referring to the various figures of the drawing, and especially Figs. 4 and 5, the connecter comprises thin upright blades 34 and 36 which project upwardly from a suitable insulation base 38. These blades are spaced apart by an amount equal to the spacing between the center and either outside rail. To apply the connecter to the track it is merely necessary to press the blades 34 and 36 from the bottom toward the top of the rails, thereby forcing the blades between the web portions 28 of the rails. This is clearly shown in Fig. 2 by the position of blade 34 in rail l8.

The slab or plate of insulation 38 is slotted beneath blades 34 and 36 and the latter are provided with extensions 46 and 42 which pass through the slots and are then bent sidewardly to underlie the insulation plate as is best shown in Figs. 3 and 5. Extensions 46 and 42 are preferably made narrower than blades 34 and 36, thereby providing shoulders 44 at the bottom of the blades which prevent downward movement of the blade through the insulation plate. Extensions 46 and 42 run transversely to the end of the insulation plate, and in order to prevent contact therebetween, are preferably sidewardly displaced relative to one another, and it is for this reason that the blades 34 and 36 are also sidewardly displaced.

The extensions 4|] and 42 are provided at their outer ends with suitable means affording electrical connection therewith. In the present case,

spring clips 46 and 48 of conventional type are mounted on top of the outer end of insulation plate 38 and are locked in place by eyelets 5!] which pass through the insulation plate and the extensions 46 and 42 therebeneath. The eyelets thus lock the extensions as well as the spring clips in place, and electrically interconnect the same.

Flexible leads or wires 52 may be connected to clips 46 and 48, as indicated in Fig. 1. These wires may be used to lead power from a'transformer or batteries to the track or may be used to connect an electrically operated accessory to the track, thereby supplying energy from the track to the accessory.

It will be noted that the connection to each rail is independent of and similar to the connection made to any other rail. The arrangement may therefore be used for connection to a single rail or to all three rails in addition to the more common arrangement in which connection is made to two rails, as shown. The connection to three rails may be useful when dealing with a special track or track section in which the outer rails are insulated from one another, as well as from the center rail. 7

I may also mention that because the blades force the web walls of the rails apart when inserted, the grip of the rails on the blades is very tight and the connecter is strongly anchored to the track. It is therefore possible to use the insulation base of the connecter for additional purposes, such as the support of special contact or trip elements or for supporting a complete trackside accessory device.

It will therefore be understood that in referring to the unit as a connecter in the appended claims, I refer to connection whether made to a distantly located accessory or an immediately localized accessory.

It will'also be apparent that while I have shown and described my invention in a preferred form, many changes and modifications may be made in the structure disclosed without departing from the spirit of the invention defined in the following claims.
