WILLIAM RITSON WILSON, OF TORONTO, ONTARIO, CANADA.

RAILWAY-RAIL.

To all whom it may concern:

Be it known that I, VILLTAM RrrsoN VIL- sort, a citizen of the United States of America, resident of the city of Toronto, in the county of York, Province of Ontario, in the Dominion of Canada, have invented certain new and useful Improvements in Railway- Rails, of which the following is a specification.

The invention relates to improvements in railway rails as described in the present specification and illustrated in the accompanying drawings that form part of the same.

The invention consists essentially in the novel construction and arrangement of parts whereby a separable head is held in place on the permanent head by a hooked flange on the one side and a straight flange on the other and is rigidly secured by a plurality of bolts to said permanent head.

The objects of the invention are to reduce the cost of maintenance of ways and to devise a rail particularly adaptable for street railway rails in which a worn head may be easily and quickly removed and replaced without disturbing the main portion of the rail and thus disrupting the roadbed and pavements.

In the drawings, Figure 1 is a sectional perspective view of a portion of a rail constructed in accordance with my invention. Fig. 2 is a longitudinal sectional view of a portion of the rail through one of the bolt holes.

Like numerals of reference indicate corresponding parts in each figure.

Referring to the drawings, 1 is the permanent part of the rail having the base 2 and a web 3 and a permanent head 4, the sides 5 and 6 of the said head 4: being unevenly distributed in relation to said web 3 to obtain a greater width on the side 5.

7 are slots arranged at intervals longitudinally in the side 5 of the head 4.

8 is the separable head of the rail havinga longitudinal groove 9, in which the flange of the car wheel travels, and a downwardly extending inturned or hooked flange 10 at one side thereof fitting snugly around and gripping the outer edge of the side 6 of the head 4, and a straight flange 11 from the other side abutting the outer edge of the side 5. The flanges 10 and 11 are formed so that the distance between them. is uniform from end to end of the rail and the distance Specification of Letters Patent.

between them is such that when the inturned flange 10 is hooked over the edge of the head 4., the inner side of the flange 11 will bring the said flange 10 to grip the permanent head on that side. The head of the rail is thus securely held from lateral displacement.

12 are bolt holes through the head 8 in the bed of the groove 9 and arranged at intervals longitudinally therein to register with the slots 7 in the head i of the permanentportion of the rail.

13 are bolts extending through the bolt holes 7 and 12 and having their heads counter sunk in the top of the holes 7 so that the upper surface of said heads will be flush with or below the surface of the slot 9.

1a are nuts on the lower end of the bolts 13 and abutting the under side of the side 5 of the head a and with the said bolts, firmly securing the separable and permanent heads together.

The longitudinal slots 7 in the side 5 provide for any slight variation in the distances between the bolt holes in the separable head so that there will be no difliculty in placing the said separable head in position besides allowing for the expansion and contraction of the metal.

The peculiar formation of the permanent head 4 is quite important, as the difference in width of the sides 5 and 6 brings the actual tread portion of the separable head centrally over the web 3 and thus the weight of the car traveling on the rail is supported vertically by the said web.

The permanent portion of the rail is made of the ordinary rail steel and is quite flexible and not liable to fracture easily, but the head 7 is preferably formed of high carbon or manganese steel to resist wear. A composite rail is thus formed which will not be liable to break through crystallization, caused by vibration, as the weight is supported directly by the low carbon steel portion and an upper running surface of a hard nature is provided to withstand the wear and tear of the car wheels.

The construction herein described has many advantageous features other than those mentioned, the peculiar arrangement of the side flanges of the upper portion holding the said upper portion securely from side play and therefore preventing any spreading of the rails and when it is desired to replace a worn rail it is not necessary to tear up a lot of the pavement but merely a few blocks are removed to allow access to the bolts when the same may be loosened and the up per portion of the rail lifted clear and a new portion placed thereon without difiiculty. Not only is the pavement around the rails saved but a saving of much time and material is effected, as repairs may be made with great celerity. Another important feature in the use of a rail of this description is that the tread portions may be arranged to break joint with the main portion so that there is no point in the rails where there is a break from top to bottom. This feature will eliminate a considerable amount of vibration and noise.

\Vhat I claim as my invention is In a device of the class described, in combination with a base, web and permanent head, said head being formed with a perfectly fiat upper surface and arranged with a greater width on one side of said web than on the other and having pointed tips formed by the curved under surface converging to said flat surface and longitudinal slots head, and a flange extending downwardly from the other edge having a sheer inner edge rounded outwardly at the bottom and a perfectly flat surface between said flanges adapted to rest on the flat surface of said permanent head, and bolts countersunk in said separable head and extending through the longitudinal slots in said permanent head.

Signed at the city of Toronto, in the county of York, Province of Ontario, in the Dominion of Canada, this eighth day of February, 1908.
