6 Claims. This application is a division of my application, Serial No; 307,127,,filed December .1, 1939,

for Railroad safety devices.

This invention relates to, railroad safety devices, and is particularly directed to means for preventing derailment oi'the trucks or cars of either a toy railroad car or regular railroad.

An object of this invention is to provide a safety device for toy railroads, including a frame having ,parallel longitudinal members slidably mounted on the wheel axles of the truck, and fins at the ends .of each of .said' members, disposed above the head of the rail and beneath the inner portion of the headof the rail and normally having a clearance with respect .to the rail, except when called into play to prevent derailment, spring units beingfurther provided between the ends of .said longitudinal members to resiliently press said membersapart, whereby the safetyfins may besnapped into-positionto facilitate applicationof the toy truck to the rails .or removal of the truck therefrom.

The purpose of the upper fin is to make it a more perfect miniature of a real regular rail of the type I am endeavoring to patent for regular railroad-s in my above-identified patent applicaifiOh. I

A further object of this invention is to provide ;a strong, rugged and durable rail safety device of the character described, which shall be relativeiy inexpensive to manufacture, and yet prac- :tical and efficient to a high degree in use.

Other objects of this invention will in part be obvious and in part hereinafter pointed out.

' The invention accordingly consists in the features of construction, combinations of elements, andarrangement of parts which will be exemplified "the construction hereinafter described, and of which the'scope of application will be indicated in the following claims.

In the accompanying. drawings, in which is shown one of the various possible illustrative embodiments of this. invention,

Fig. 1 is a top plan view of toy rail tracksand a truck mounted thereon and provided with safety derailment device, embodying the invention.

Referring now in detail to the drawingsFi'gs. 1 to 6 are directed to toyrailroad construction, embodying the invention, designated by numeral l6. Said railroad construction comprises rail ties H, on which are mounted rails l2 attached to the ties, in any suitable manner, and a third rail [4 mounted on the ties H and disposed between the rails l"2.,

.Fig. dis an-enlarged cross-sectional view taken on line 4-4-of Fig. .2.

Fig. .5 is across-sectional yiew taken on line openings 36 at its outer ends.

On the rails 12 is a truck l5 supporting a car and comprises a pair of side frames l1 carrying parallel axles 18, on which are carried wheels 16, rolling on the rails l2. The side frames H are inter-connected' by the usual spring assembly 21, on which the car I6 is mounted.

Means is provided to prevent the derailment of the truck. To this end, there is slidably'mounted on the axles, and disposed between the wheels IS, a safety frame 25. The same comprises a pair of similar, symmetrically disposed, parallel, longitudinal side members .26 disposed beneath the spring assembly .21 and formed with semicylindric'al notches 2'! .to receive the axles. Bolted .to the members 26, are members '28 formed with'semi-cylindrical notches to receive saidv axles. The side members 26 are thus slida'bly mounted on the axles and may be moved toward one another, as will appear hereinafter.

Each side member 26 is formed with threaded Riveted to the outer end of each member 26, as by rivets 3|, is a member 32 having a wall 33 contacting the outer wall 36 is formed with a threaded opening 39 registering with one of the threaded openings 30.

"To limit movement of members 26 away from each other, there is provided at each end of the safety frame 25, a strap member 42 having parallel arms 44 overlying walls 33, and formed with openings43, and a portion inter-connecting said arms.

Screwed within the

openings

30 and 39 are aligned, symmetrical, inwardly extending pins 41,

loosely passing through the opening 43 and formed with reduced inner end portions 48, for the purpose hereinafter appearing.

Mounted on each pair of aligned pin portions 48, is a sleeve 50 slidably receiving said pin portions, and disposed parallel to strap 42. On each of the ends of the sleeves 50 is a sleeve 5!. Interposed between the sleeves 5|, and disposed on sleeve 50, is a coil compression spring 52 servthe truck may be lifted off the rail. When the truck is mounted on the rail, side members 26 are first pressed toward each other, and the truck placed on therail. The side members are then released, so that the springs 52 snap the safety devices 32 into position for preventing derailment of the truck.

It will be noted that under ordinary conditions, the flanges or

fins

36 and 31 of the flanges 38 do not contact the rail head or the rail, so that there is no friction or wearing of parts.

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 set forth, it is to be understood that all matter herein set forth or shown in the accompanying drawings, is to be interpreted as illustrative and not in a limiting sense.
