RAILROAD-RAIL.

Specification of Letters Patent.

Patented Jan. 22, 1907.

Application filed May 8, 1905. Serial No. 259,454.

To all whom, it muy concern:

Be it known that I, MARK W. TRIMBLE, a citizen of the United States, residing at Idabel, in District 24, Indian Territory, have invented certain new and useful Improvements in Railway-Rails, of which the following is a specification, reference being had therein to the accompanying drawings.

My invention relates to new and useful improvements in railway-rails, and more particularly to that class wherein devices are employed to prevent the cars from leaving the track, one of the objects being to provide a device of the character described that shall be simple in construction, durable, and effective in operation.

A further object of my said invention is to provide a device of the character described whereby means shall be formed integral with the rail, which effectually prevent the cars from leaving the `track when by reason of broken flangesl or other accidents to the wheels they are so disabled as to permit of their leaving the rail now commonly in use.

Other objects and advantages of my invention, as well as the structural features by means of which these objects are attained, will be made clear by an examination of the specification, taken in connection with the accompanying drawings, in which the same reference-numerals indicate corresponding .portions throughout, and in which-- Figure 1 is a top plan of a railway-track constructed in accordance with my invention. Fig. 2 is a transverse section on line 2 2 of Fig. 1, and Fig. 3 is a perspective view of a portion of a rail constructed in accordance with my invention.

1 designates a railway-rail constructed somewhat in the form of the well-known T- rail now commonly in use.

2 designates the base of the rail, which eX- tends sufficiently beyond the edge of the top 3 to permit of the spikes being driven through the holes 4 into the ties 5 instead of having j the heads of the spikes clench the outer edge of the base, as in the present well-known method.

6 designates a flange formed integral with the rail when cast and which may be disposed at any desired angle with the rail and extend to any desired height above the same.

7 designates braces disposed at suitable distances apart and which pass through the rails and are secured thereto in any suitable manner andv which have the effect of preventing the rails from spreading.

In operation when a swiftly-moving train is passing upon a track constructed in accordance with my invention and for any reason any of the wheels on either side should leave the track, so as to throw the flanges on top of the rail 3, the outer edge of the wheel will come in contact with the flange or proj ection 6, which would effectually prevent the cars from leaving the track, the wheels being suciently wide to allow those on the opposite side to still remain in engagement with the top 3 of the opposite rail, and thus by the use of my invention many of the accidents now caused by broken flanges enabling the cars to leave the track would be avoided and trains would be enabled to run at a much greater rate of speed than `at present and with less danger than at the ordinary rates of speed now attained.

Having thus described my saidinvention, what I claim as new, and desire to secure by Letters Patent of the United States, is-

A railway-rail having a base, a head, a web uniting the base and head, and a straight, upwardly and outwardly projecting guardflange extending longitudinally from end to end of the rail, said guard-flange being formed integral with the web of the rail and projecting angularly from one side of the web at a point below the head of the rail, substantially as shown and described.

In testimony whereof I hereunto afliX my signature in presence of two witnesses.

MARK W. TRIMBLE.
