' RAILWAY CROSSING.
No. 588,737. 8 Patented Aug. 24, 1897.
UNITED STATES PATENT OFFICE. v
ALFRED HUGH TYLER, OF LONDON, ENGLAND.
RAILWAY-CROSSING.
I SPECIFICATION forming part of Letters Patent No. 588,737, dated August 24, 1897. Application filed May 4:, 1896- Serial N5. 590,176. (No model.)
To 00% whom it may concern.-
Be it known that I, ALFRED HUGH TYLER, a subject of the Queen of Great Britain, residing at London, in the county of Middlesex, England, have invented certain newand useful Improvements in Railway-Crossings; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.
This invention, which relates to improvements in railway-crossings, has for its object the construction of railway-crossings from rails of the ordinary sections in a simpler and more efficient manner than heretofore and from a less number of rails than is usually. employed, the invention comprising the bending, grooving, and arranging of the rails used.
In the drawings accompanying this specification, Figures 1, 2, and 3 are plans showing different arrangements of the rails for crossings.
According to the present method of construction railway-crossings are made from four separate rails, which are out, bent, and fixed according to the crossing required. Now according to the present invention, the crossings are made from two or three rails only which are bent at the required angle, and are grooved upon their upper face for the flanges of the wheels to run in when the wheel. is passing over the crossing. The crossings may be made from rails of any of the usual sections, and the grooves are preferably formed by means of hydraulic presses, which are so arranged and operated and the dies so shaped that the material displaced in the formation of the groove is pressed back into the body of the rail, thereby maintaining the section of the rail at the grooved portion equal in strength to the section of the rail itself and dispensing with the use of rails of special section. A convenient form of press for the above purpose has two cylinders fixed at right angles to each other and one or more fixed dies.
I11 the crossings shown in the drawings the rails are so bent and grooved that each rail forms part of the through line and also part of the crossing line.
In Fig. 1 the rail Z has a single bend at Z and grooves Z on both sides of such bend. The other rail m is then bent at m to fit the bend in the rail Z and at 'm and m to form continuations of the rail Z. A check-rail n may be bent and fixed as shown.
In Fig. 2 the rail 0 is bent at o o 0 and is grooved at 0 on both sides of the bend 0 The rail 19 is bent at p, but is not grooved, and there is sufficient space between the rails 0 and p to allow of the flanges of the wheel passing. A check-rail q may be used with this crossing, if desired.
In the crossing shown in Fig. 3 the rails r and s have a straight portion between the two bends s, and the rail r has two grooves r forme'd'in it, these grooves running into each other. A check-rail isused with this crossing.
These crossings may be made from rails of any of the usual sections, and are bent and grooved according to the crossing. required. They are also fixed by any of the usual means.
Having thus described my invention and the means for carrying out the same, What I desire to claim and protect by Letters Patent in the United States of America is- 1. A railway-crossing comprising an angular rail arranged to constitute part of the through line and part of the crossing line, and formed with two grooves one arranged parallel with the through line and the other parallel with'the crossing line, substantially as set forth.
v 2. A railway-crossing comprising an angular rail arranged to constitute part of the through line and part of the crossing line, and formed with two grooves one arranged parallel With the through line and the other parallel with the crossing line, and another angular rail arranged to constitute part of the through and part of the crossing line, the latter rail not being grooved, substantially as set forth. N
3. A railwaycrossing comprising two angular rails, one having a single obtuse angle,
and the other three angles whereby the anand the arrangement of such rails whereby gular portion is in substantially the form of each rail forms part of the through line and 10 a fllattened W, the angular parts of the two also part of the crossing line. mi 5 bein arran ed 0 osite to each other W H T 5 sllbstantiglly as s et fo th. ALFRED HUGH l 3 4. A railway-crossing constructed of two Vitnesses: rails only one of which has asingle bend and JOHN STUART ELLIS DE VESIAN, two grooves, and the other rail three bends, RALPH GoooH TYLER.
