WILLIAM F. BOSSERT, OF UTIOA, NEW YORK.

RAILWAY C HA IR AND BRACE.

SPECIFICATION forming part of Letters Patent No. 747, 31, dated Decemb r 29,

Applioation filed May 12, 1903.

To all whom it may concern:

Be it known that I, WILLIAMF. BOSSERT, residing at Utica, in the county of Oneida and State of New York, have invented certain Improvements in Railway Chairs and Braces, of which the following is a specification.

The present invention relates to means employed to support railway-rails in position upon the ties on the road-bed. In straight runs of track the rails are fastened to the ties by means of bolts or spikes, which, with the chairs at the ends of the rails, form asufficient support, but upon curves, where the wheels of the train are forced over upon the outer rail with great force and thrust, more protection is demanded to hold the rail firm and stable.

My invention provides means whereby upon curves the rails are not only securedto the ties, but are provided with a strong and sufficient brace to withstand the thrust of the train when passing rapidly over the rails; and it consists of a plate passing under the rail-from the innerto the outer side, provided with slots on the inner side for the reception of bolts or spikes near the inner edge of the rail and upon the outer side returning upon the plate to the outer edge of the rail and then extending upward as a strut in an inclined direction to the rail-tread in a manner to lock therewith and support the same.

Notches are cut in the outer edge of the doubled portionof the base for the reception of bolts or spikes.

The combined chair and brace is made in one piece of rolled metal about four inches wide and is bent by machinery into the desired shape, and the spike-holes and notches.

are made by a templet, so that each piece is like all the others, all of which I will now proceed to describe, and point out in the appended claims.

In the drawings which illustrate the invention, Figure 1 is a perspective View of the chair and brace in position upon a rail. Figs. 2 and 3 are end views of modified forms of the chair and brace. Fig. 4 is a section online a; a: of Fig. 2, and Fig. 5 is a modification.

Referring to Fig. 1, ct represents a rail, of

which 1 is the thread, 2 is the web, and 3 3 Serial No. 166.768. (No model.)

and brace in position with the rail. The chair and brace b is made from a piece ofiron or steel of even thickness and width and is preferably out 01f from a long flat bar in a suitable length. A portion 4 is left flat for a sufficient length to form a base for the foot 3 of the rail and a turn made, as 7, at which forash'ort distance the bent-over part is parallel and in contact with the base 4, and then a bend is made at preferably an angle of sixty degrees (although this angle is not strictly essential) with the base 4, inclining toward the rail, and when near the point 12 at the base of the rail-tread the material is given a sudden bend outward at 11 and then an abrupt bend upward at 9* and continues straight for a short distance 9 and then returned-or doubled upon itself at 9 at about the level of the top of the tread 1. The material or bar bis thenmade to conform to the inner surface of the portions 9, 9, and 8, and its end terminates-upon the outer and upper surface of the rail-base 3, and when completed the straight part 10 bears against the face of the tread 1. The concave part fits upon the lower convex corner of the tread, and the rounding shoulder 11 fits into the curved portion part 12 at the junction of the tread with the web. Suitable slots 5 5 are punched in the end of the straight or base part 4 of the brace bnear the edge of the rail-base 3 for the reception of bolts or spikes, and cuts are made, as 6 6, through the doubled-over part '85 7, also for the reception of boltsor spikes to secure the brace to the rail-ties. By this construction a combined chair and brace is made which. when secured to the rail and tie by bolts holds the rail in a firm'embrace and supports the same, as the rail-foot 3 enters the space 14 made by the part 4, the inclined strut 8, and its companion strut 13, which is shortened to form the pocket or space 14. At

the same time the shoulder 11, socket 10*, and 5. abutment 9 support the rail-tread and fit its outward contour, and any thrust made by the train-wheels to force the rail against the brace is met by the same and resisted.

In Fig. 2 but one strut 8 is formed on the bar 19, which is provided withthe shoulder 11 fitting into the concave 12 at the juncture of the tread with the web, the portion 9 also being of a single thickness and ending at about the level of the tread. In this case the foot 1 upper part of the rail, and returning upon 3 of the rail rests in the angle formed by the base 4: and the struts 8 and is held firmly in place.

In Fig. 3 the construction is the same as in Fig. 1, except that the outer strut 8 is not bent at the upper part so abruptly as is the inner shoulder 11, so as to leave an open space 18 between the bend 15 and shoulder 11. By this arrangement an angle is formed which gives additional support to the railtread. One or more ribs 23 may be formed upon the struts by forcing the central part outward, as indicated, to further strengthen the same. I form sharp projections 22 in the base portion 4 by forcing parts thereof downward (shown as made three-cornered) in order that when the chair is placed upon a tie T they may be forced thereinto and hold the chair from slipping from its place. It will be seen that the projections are one side of the line of the bolt-holes 5 and 6 in order that the tie may not be split, as it would be by four holes in line with one another in the same, and the points of the projections are made to cut their longest score in the direction of the fiber of the tie instead of across the grain in order not to weaken it.

In the modification shown in Fig. 5 the chair is tied together by the bolt B, which extends through the struts 8 and 13 and the web 2 and has a head D, bearing upon the web, and a nut 0 upon the outer threaded end. A block A is placed between the nut O and the face of the strut 8 in order to provide a broad base for the nut and distribute the stresses. The block is preferably made of iron. It is intended in this modification to employ the projections in the plate bearing upon the tie.

I claim as my invention-- 1. A railway chair and brace, consisting of a strip of iron or steel havinga plate extending under the rail from one side to the other,
