SAFETY DEVICE FOR RAILW'AY-TRACKS.

Specification of Letters Patent.

Patented Feb. 21, 1911.

Application filed May 1, 1910. Serial No. 559,373.

To all whom it may concern:

Be it known that we, ROBERT E. CARLTON, a citizen of the United States, and a resident of Latonia, in the county of Kenton and State of Kentucky, and MARCUS JV. RYLE, a citizen of the United States, and resident of Balniorhea, in the county of Reeves and State of Texas, have invented certain new and useful Improvements in Safety Devices for Railway-Tracks, of which the following is a specification.

Our invention relates to improvements in guard rails for preventing the derailing of cars on railway tracks, and it consists in the combinations, and constructions and arrangements of parts herein described and claimed.

An object of our invention is to provide a device which may be advantageously used at points at which there is danger of derailment, such as on curves, or upon bridges, or other structures, where derailment would lead to the most serious consequences.

A further object of our invention is to provide electrical means for notifying the operator if the derailment should occur and at what point.

A further object of our invention is to provide a novel form of guard rail for preventing the derailment of the train and serving to effect the reentrance of the wheels upon their proper rails if such derailment should occur. This is accomplished by means of grooves made in the rails in such a manner that the flanges of the wheels are guided by the grooves so that the wheels themselves are turned back upon the main track.

Further objects and advantages will appear in the following specification and the novel features of the device will be particularly pointed out in the appended claims.

Gur invention is illustrated in the accompanying drawings, in which:

Figure 1 is a plan view of the track provided with our invention. Fig. 2 is a side view of a portion of the track showing the spring for actuating the switch tongue. Fig. 3 is a section along the line 33 of Fig. 1, Fig. 4 is a section along the line 44 of Fig. 1, and Fig. 5 is an enlarged section along the line :55 of Fig. 1.

In Fig. 1 we have shown a track comprising the ties 1 and the main rails 2 and 3. In

a section of track, at points where derailment is liable to occur, such as on curves, we remove the rails of the main track and insert in place thereof the rails shown in Fig. 1. In this figure it will be seen that there is an outer rail 4 of a curved shape which is placed between the sections of the main rail 2, being secured to the ties 1 in the ordinary manner. Inside of the outer rail 1 is a rail 5 which is in line with the main track rails 2--2 and which is provided with pivoted switch tongues 6 and 7 at the ends thereof. This rail is provided with a series of diagonal grooves 8. lVithin the rail 5 is a third rail or inner guard rail 9 having a curved form as indicated in the figure, the curve of the rail being opposite to that of the outer guard rail 4;. The inner guard rail 9 is also provided with a series of diagonal grooves 10. Between the track rail 5 and the outer rail 4: is a steel or iron spacing plate 11, while a similar spacing plate 12 is placed between the rail 5 and the inner guard rail 9.

The opposite side of the track is similarly provided with an outer guard rail 13, and the inner track rail 14 which has diagonal grooves 1%. A third rail 15 is provided which is similar to the rail 9 and is provided with grooves 16. The rail 14 is provided with the switch tongues 17 and 18 similar to the switch tongues 6 and 7 On the outer side of each of the rails 41 and ,13 are secured springs 19. Each of these springs is connected by a rod 20, which passes through the opening in the outer guard rails, with its respective switch tongue, as plainly shown in the drawing. These springs tend to hold the switch tongues against the outer guard rails so as to form a continuous section of track between the main track sections 22 and 3 3. The rail sections are joined together by means of the fish-plates 21 and the rails are secured to the ties in the ordinary manner.

From the foregoing description of the various parts of the device, the operation thereof may be readily understood.

Ordinarily as a train passes a section of track provided with our invention, the wheels on one side of the train follow the track 2, 5, 2, since as before stated, the switch tongues 6 and 7 are normally held by their springs so as to form a continuous track. The wheels on theoppositeside of the train would follow the rail sections v ;=8e1 l8. '7 Now, if one of thewheels should jump the track the inner or outer guard rails would prevent the train from complete derailment. Moreover, as the train proceeds,

the flanges ofthe wheels will'engage the diagonal grooves, thereby tending to force the wheels back upon the track. The grooves are shown as inclined in opposite directions, so that if the tram 1s proceeding 1n one (11- rection, as forinstance, from left to right, in

V r Fig. lfthefianges-on thewheels, on the left I hand side of the train will-engage the" grooves 8 and tend to force the wheels back upon the tracln If the-derailment is still farther to the left, the grooves of the rail 15 will engage the flanges of the wheels of V the/right hand side of the'train and tend to force the wheels back uponthe track. Conversely, if the-derailment should be in the opposite direction, the grooves 14;? of the rail 7 Hand grooves 10 of the rail 9 would come in 'vide' the spring tongues'6,- r7 and 17, 18. As

- soon as the flanges, which engage one of the outer guard rails, reach the spring tongue, they push it aside, and the tongue may spring back into its position, thus leaving the apparatus in normal condition.

'We areaware that other forms of the device based upon thesameidea might be made, but we consider as'our own all such modifications'as fairly fallfwithin the spirit and scope of the invention.
