Serial No. 393,804.

This invention relates to means designed for derailing tubs, trucks, and other railway vehicles, or diverting them off a permanent way or track, in the event of their runn ng away down or along the track, or attaining an excessive or uncontrollable speed; and the present application is a division of application Serial No. 848,581, filed March 20, 1929, Patent No. 1,749,808, March 11, 1930.

The invention is applicable for use on railway tracks of any description, for derailing, diverting, or throwing oft the track, tubs, trucks, or other railway vehicles or the like, whether loaded or empty, which have acquired a predetermined excessive or uncontrollable speed on the permanent way or track.

The means according to this invention constitutes a simple and eliicient device for the purpose specified which, when the vehicles are running at or below the normal or a predetermined maximum speed, will allow them to remain on the track, and will operate, only on such speed being exceeded, to derail the vehicle.

According to this invention the derailing device consists of a definite setting in or shaping of the track, so as to impart to, a portion or portions thereof a transverse set or lateral kink or bend, with an upward grade or incline (relative to the level of the rails of the track) in front of'the set or bend, in the direction of the travel of the vehicle along the permanent way, and cooperating withsaid set or bend.

The transverse set, or lateral kink or bend, causes the vehicle tobe deflected or diverted laterally from the normal direction of travel and to be returned to the same direction when the vehicle is runmng at normal or safe speeds. The upward grade or incline,

in conjunction with the set or bend, causes the vehicle to be derailed when it acquires an excessive or uncontrollable speed; whereas, at normal or safe speeds, the vehicle passes over the device without being derailed. It will be understood from the foregoing that the construction of the device is such that the upper surface of the deflecting device rises above the normal plane of the rails of the trackf-rom both endsoi the device. I The invention will be more fully explained with the-aid of the accompanying drawings, wherein, j

Figs. 1 and 2 are plan view and side elevation, respectively, of a portion of the permanent way or track, incorporating the in: vention. l

As illustrated in the drawings, the device is shown incorporated in the rails 1, 2, of the permanent way or track. The rails 1, 2, are upwardly inclined or bent from the points 3 to the pointsa, and then downwardly inclined or bent from the points 4 to the points 5, and the downward incline is continued to the points 6. From the points 6 to the points 7 the portions of the rails 1, 2, lie in the normal plane of the track. The transverse set or lateral bend is formed in the rails l,

2, between the points 5 "and 7 and from the points? the rails 1, 2, continue in the normal direction of the tra ck'lout with the rails at the one side of the device out of alignment with the rails at the other side thereof. Although the track is shown as a hori- -zonta'l track, it is to be understood that it may be either upwardly 'or'downwardly inclined andthe device still operate to derail the vehicle under the conditions hereinbeiore mentioned. The rails are so shaped and arranged relative to each other in the track that the sets or bends formed therein are symmetrical and incline laterally in the direction ofthe same side of the track, so that the gauge is maintained for the full length of the derailing device.

8, 9. represent two of the sleepers of the permanent way or track, on which sleepers the rails 1, 2, rest and are secured, and in the portions of the rails between which the in vention is embodied.

As will be apparent from a consideration of the invention, the set or shaping of the rails 1, 2, is such that, in the event of a vehicle passing on to the derailing means at an excessive speed, it is diverted or deflected upwardly relative to the normal plane of the track, by the upwardly inclined portions 3-4, and, due to its momentum, tends to continue in the same direction, as indicated by the dotted lines a. The action of gravity compels the wheels of the vehicle to travel or move in a curved path or trajectory, as indicated by the dotted curve 6 in Fig. 2. This causes the wheels to leave or jump clear of the track, thereby resulting in the derailment of the vehicle.

In the drawings the rails 1, 2, in which the derailing means is incorporated, are shown a supported by sleepers, but it will be apparent that they may be otherwise supported, as for example by arranging them, or portions of them, upon a metal plate or plates, or on a cast base; or they may be cast or otherwise constructed integral with a base or base portion.

It follows from the foregoing description that the device as described and illustrated, is entirely self-contained, and that there are no moving parts liable to get out of order, as in existing arrangements employed for the purpose. Further, that my improved device is not, like the existing arrangements, difiicult to install. It does not call for special attention, and does not require the amount of space which is necessary for the working parts of existing devices. My device, being of simple construction, is inexpensive to produce and cannot get out of order. It is light in weight and inexpensive to install.

What I claim as my invention and desire to protect by Letters Patent is A railway permanent way or track, a portion of which is constructed with a transverse or lateral set or bend and an incline formed in the track or permanent way in front of the set or bend and co-operating with said set or bend, whereby the vehicles are derailed when they acquire an excessive or uncontrollable speed, asset forth.

In testimony whereof I have signed myname to this specification;

COLIN OLIVER DEACON. I
