Improvement in Railroad Rails.

UNITED STATES PATENT CEEIGE.
JOHN DOWNEY, OF J OHNSTOWN PENNSYLVANIA.
IMPROVEMENT IN RAILROAD RAILS.
Specification forming part of Letters Patent No. 132,451, dated October 22, 1872.
To all whom t may concern:
Be it known that I, JOHN DowNEY, of Johnstown, in the county of Cambria and State ot' Pennsylvania, have invented a new and Improved Iron and Steel Continuous Rail, as applied to railways, of which the following is a specification:
Figure l is aplan view ofa track formed of rails constructed and supported between iron sections or flanged bars secured together according to my invention. Fig. 2 is a sectional elevation oi' the same. Fig. 3 is a side view ofthe rail and one of its iianged supports. Fig. 4t is a cross-section of a rail and its anged supports, showing the hook or locking bar.
My invention relates to an improvement in the class of compound railroad rails where-- in the rail proper is secured between ilanged side-bars; and it consists in applying a clamping-bar to unite the flanged bars and the rail, as hereinafter described.
In the drawing, A indicates a rail having a steel head, provided with a longitudinal tongue, a, and B, iron sections or rbars, provided each with lateral and vertical iianges or extensions I) c. These parts are Iitted t0- gether, as shown in Fig. 4, so that the plane surfaces of the bars B lie tlat against .the tongue a of the rail A, and their upper edges form bevel shoulders on which the head of the rail rests. As a means of locking the parts together, l employ a bar, C, which is formed with a hook at one end. This hook or clamp bar ts over the lateral ange of one ofthe bars B, and the other end of the saine is turned up over the corresponding flange of the opposite bar B. Thusthe bar G passes intermediately through slots in the respective parts of the compound rail and locks them together. rail are made larger than those in the bars B, so that no strain from expansion orv contraction ofthe parts, or from the weight of trains passing over the rails, may be brought upon the bars C.
In practice I design to make the rail and its supports B oi' equal length, and to lap the supports past the rail for one third their length, as represented in Fig. 2. Thus arranged they will break joints7 with the rail and form a continuous bearing for it. That part of the compound rail which projects below the lateral iianges lits in transverse slots in the sleepers, and said flanges rest on the upper surface thereof. By this arrangement of the clamp-bar with the parts composing the rail they are locked together in the most secure and durable manner.
I do not claim a clamp-bar in combination with arail or rails, but,
Havingthus described my invention, what I claim as new, and. desire to secure by Letters Patent, is-
The hook or locking bar C, arranged with the bars B B b c and tongue a of the rail A, in the manner described.
