EDWARD BOSWELL MALCOLM, 0F CAMPBELLTON, NEW BRUNSWICK, CANADA.

SAFETY DEVICE FOR RAILWAY FROGS AND GUARD-RAILS.

Application filed July 15, 1913.

Specification of Letters Patent.

Patented July 21, 1914.

Serial No. 779,181.

To all whom it may concern Be it known that I, EDWARD BoswELL MALCOLM, a subject of the King offGreat Britain, and resident of the town of "Campbellton, in the county of Restigouche, Province of New Brunswick, Dominion of Canada, have invented certain newand useful Improvements in Safety Devices for Railway Frogs and Guard-Rails; and I do hereby declare that the following is a full, clear, and exact description of the same.

The invention relates to improvements in safety devices for railway frogs and guard 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 in relation to frogs and guard rails in railways whereby the permanently open spaces between ra-il members are protected by a self adjusting plate.

The objects of the invention are to avoid the derailment of railway vehicles in passing over frogs and approaches to bridges and other places, to devise a simple and inexpensive means of maintaining a free space for the flanges of the railway vehicles, and generallv to insure safety for life and property in an eflicient manner.

In the drawings, Figure 1 is a plan view of the device applied to a rigid frog. Fig. 2 is a. longitudinal sectional view of the device as generally applied to cover in the space between two rail members. Fig. 3 is av plan View of the device applied to a spring frog. Fig. t is a plan view of the device applied to a guard rail.

Like numerals of reference indicate corresponding parts in each figure.

Referring to the drawings, 1 is the frog having the outer rail members 2 and 3 and the inner rail members 4 and 5 terminating in the point 6.

7 is a plate of spring material shown in Fig. 1 as forked at one end, said forked ends 8 and 9 extending between the said outer and inner rails, the other end of the plate filling in the space between the outer rails beyond the point 6. The spring plate 7 at the forked ends 8 and 9 is bent downwardly and terminates in the curled extremities 10 and the opposite end is bent downwardly in an easier curve and terminates in a curled extremity 11. Intermediate of the length of said plate 7 the metal 1s bent inwardly to form the U-shaped recess 12 there across adjacent to the beginning of the bend leading to the extremity 11. About central in said plate and adjacent to the point 6, 13 is a bolt hole. Toward the curled extremities 11, 1 1 are lateral lugs extending under the heads of the outer rails 2 and 3. It will now be seen that the plate fills in the spaces between the rails forming the frog as shown in Fig. 1, and is substantially even with the upper surfaces of the rail heads and at the forked ends maintained in that. position by the lugs 14. 15 is a bolt inserted through the webs of the outer rails 2 and 3 opposite the U-shaped recess 12 and engaging the said plate 7 in the bed of the said recess, consequently holding said plate 7 at that end from springing up above the rail heads.

16 is a bolt having its head suitably countersunk in the plate 7 at the bolt hole 13 and extending downwardly through an anchor plate 17 below the frog and at. its lower extending end held to said anchor plate by the nut 18, said nut being locked home by the cotter pin 19 extending through the center shank of the bolt.

20 is a spring encircling the bolt 16 between the under side of the plate 7 and the anchor plate 17 and adapted to support said plate 7 in its upper position and to return said plate 7 to its upper position after being depressed by the flange of a passing vehicle.

In Figs. 3 and 4 the only difference in the construction is the shape of the spring plate, and perhaps a slight difference in the position of the bolt hole and bolt, otherwise the invention is precisely the same, though it must be understood any shape of plate may be used according to the construction of the double rails and further changes may be made in the construction in regard to holding the said plate to its position or returning it to its upper position, so long as the construction is kept within the scope of the claims for novelty following.

What I claim is 1. In a safety device for frogs or guard rails, a plate of spring material suitably shaped and fitted between two railway rails, said plate having downwardly curved ends terminating in curled eXtremitles engaging the bases of the rails, a bolt hole there through intermediate of the length thereof and a U-shaped recess extending thereinto from the top and completely across between said bolt hole and one end, and a lateral lug at the other end, a bolt extending through said bolt hole and engaging said plate, an anchor plate engaging the other end of said bolt, a spring encircling said bolt between said anchor plate and said spring plate, and a bolt engaging the Webs of the rails and inserted through said U-shaped recess and engaging said spring plate in the bed of said recess.

2. In a safety device for frogs or guard rails, a plate of spring material covering the space between a plurality of rail heads and substantially flush with the tops of said rail heads, said plate having a bolt hole intermediate of the length thereof, lateral lugs at one end extending under the rail heads, downward bends toward the Copies of this patent may be obtained to other end forming a U-shaped recess and downwardly curved ends terminating in curled extremities and engaging the bases of the rails, a bolt inserted through the webs of the rails and enga ng said spring plate in the bed of said U-shaped recess, a bolt inserted through said bolt hole having its head countersunk in said plate, anchor plate engaging the lower end of said bolt and held thereto by a suitable locked nut, and a spring inserted in said bolt between the anchor plate and the spring plate and maintaining said spring plate in its upper position flush with the top surfaces of the rails.

Signed at the town of Cainpbeilton this twenty-third day of May, A' D. 1913.
