I PETER BARGION, OF OAKLAND, CALIFORNIA.

CHAIR-PLATE FOR COMPOUND RAILWAY-RAILS.

SPECIFICATION forming part of Letters Patent No. 461,729, dated October 20, 1891.

Application filed July '7, 1891. Serial No. 398,645. (No model.)

To all whom it may concern.-

Be it known that 1, PETER BARGION, a citizen of the United States, residing at Oakland, in the county of Alameda and State of California, have invented certain new and useful Improvements in Chair-Plates for Compound Railway-Rails; and I do hereby declare the following to be a full, clear, and exact description of said invention, such as will enable others skilled the art to which it most nearly appertains to make, use, and practice the same.

My invention has relation to certain new and useful improvements in street-railway chair-plates, which will be hereinafter more fully set forth in the drawings, described, and pointed out in the specification.

My improved chair plate or brace is adapted to be used more especially in connection with compound street-railway rails and to pass beneath the base-rails at the point of union, in order to provide a firm brace or foundation for the rail-joint for the purpose of providing against j olting or sagging of the rails at their ends, due to motion of the cars, loose or uneven road-beds, thereby giving a smooth and cess may be had to the bolt-nut without disturbing the surrounding pavement.

Referring to the drawings forming a part of this specificatiomwherein similar letters of reference denote corresponding parts, Figure 1 is a perspective view showing chair brace or plate secured in position; Fig. 2, a cross-section on line at m, Fig. 1 and Fig. 3, a detail view of the chair brace or plate;

The letter A indicates the sub or base rail provided with a broad base and vertical flanges a a, which extend upward a short distance on each side of the central line, thus formingalongitudinal openingb,withinwhich the depending stem 1) of tread rail B is adapted to fit and be secured therein by means of bolts 13', extending through the vertical flanges and depending stem.

The chair brace or plate is'represented by the letter O, and said brace fits beneath the sub or base rail, so as to receive the end of each rail, thus forming a solid and even foundation at each joint of the track, thereby preventing sagging of the rails at their weakest point, consequently providing an even surface to the tread-rail. The sub or base rail is united to the chair brace or plate by means of bolts 0, and by means of shoulders or projections c the same is prevented from lateral movement, consequently holding the rail in true line, whether secured thereto or not. The

brace-plate is provided with flanged ends 0',

which extend upward on each side of the rail and the height of the tread-rail. 'The pavement adjoining the track being laid orbuilt around the flanged ends, it is obvious that side pockets d are formed thereby, and inasmuch as said brace-plates are placed beneath the point of securing the rails it will be noticed that ends of bolts B project therein. These side pockets are filled by loose blocks or removable section of the pavement, so that in case it becomes necessary to repair the rails the upper or tread rail may be easily removed without disturbing or destroying the adjoining pavement.

It will be thus observed that my improved chair brace or'plate not only serves to provide a level and solid foundation for the rails at their weakest point, but also tends to keep the adjoining pavement in proper condition during repairs of the road. By removing the loose blocks or filling from the pockets easy access may be had to the securing-bolts for the rails in order to remove the tread-rail or make repairs. Intermediate the chair-plates the pavement fits closely against the rails,

and thus tends to give strength and solidity- Having thus described my invention, what I claim as new, and desire to secure protection in by Letters Patent of the United States, 1s

1. The combination, with a compound railway-rail, of achair-plate upon which the lower rail bears, said plate extending upward on each side of the rail so as to provide side pockets, into which the securing-bolts of the rails extend, as and for the purpose set forth.

2. The combination, with a compound railway-rail, of a chair-plate passing under and secured to the sub-rail, said plate provided with flanged ends extending upward on each side of the rail so as to form pockets, into PETER BARGION.
