SPECIFICATION forming part of Letters 'Patent o. 436,988, dated September 23, 1890.

Application tiled February 20, 1890. Serial No. 341,207. (No model.)

7'0 all whom t may concern.-

Be it known that I, ARTHUR J. MOXHAM, of Johnstown, in the county of Cambria and State of Pennsylvania, have invented a new and useful Improvementin Rail-Chairs, which invention or improvement is fully set forth and illustrated in the following specification and accompanying drawings.

The object of this invention is to provide a rail-chair having diagonal rail clamps, clips, or braces integral therewith without cutting away the fioor or rail-seat of the chair.

The invention will iirst be described in detail, and then particularly set forth in the claim.

In the accompanying drawings, Figure 1 shows the chair in end elevation, with arail, shown in cross-section, in place. Fig. 2 is a side elevation of Fig. l, looking to the right. Fig. 3 shows the chair in plan, the rail being omitted. Fig. 4 shows the chair in perspective, the rail being omitted. Fig. 5 shows in perspective the blank or shape of metal out of which the chair is made.

In said figures t-he several parts are respectively indicated by letters of reference, as follows: The letter A indicates the outside brace of the chair; a, the inside brace of the chair, located diagonally opposite the brace A; B, the sides of the chair; c c, its feet; b, the railseat, and R the rail.

The dotted lines in Fig. 4, in connection with the base b in full lines, indicate the blank of metal (shown in perspective in Fig. 5) out of which the chair is made.

The chair is constructed by first rolling a blank of metalinto the approximate H shape shown in Fig. 5 and then cutting away the portions D, indicated bythe dotted lines. The two upright portions A a are then bent to conform to the shape of rail used, and the two lower sides B B are bent outward, as shown in Fig. 4,'to form the feet or flanges c c.

Itis evident that a chair constructed as herein described can be adapted to seat and -hold various forms of rail without departing from this invention.

It desired, instead of extending the portions A
