ED\VARD B. ENTVISLE, OF J OHNSTOW'N, PENNSYLVANIA, ASSIGXOR TO THE J OIINSON COMPANY, OF SAME PLACE.
BOX-CHAIR FOR RAILROAD-RAILS.
SPECIFICATION forming part of Letters Patent No. 442,175, dated December 9, 1890. Application filed May 26, 1890. Serial No. 353,197. (No model.)
5 and useful BOXChflll' for Railroad R-ails,
which invention is fully set forth and illustrated in the following specification and accompanying drawings.
The object of this invention is sufficiently 10 indicated by its title above given.
The invention will first be described in de tail, and then particularly set forth in the claim.
In the accompanying drawings, Figure 1 r 5 shows the chair in end elevation having a rail, shown in cross-section, seated thereon. Fig. 2 is a side elevation of Fig. 1, looking to the right. Fig. 3 is a view in plan, and Fig. 4 a view in perspective, of the chair, the rail 20 being omitted in both figures.
In said figures the several parts are respectively indicated by letters of reference as follows: The letter A indicates the chair proper; a, the rail-seat; B B, the vertical sides of the chair, and b 1) its lower flanges or feet. The letters 0 0 indicate two lugs, located diagonallyopposite each other, stamped out of the sides B B of the chair and bent over to clamp the lower flanges of the rail, as shown in Fig. 1. The spaces left in the sides of the chair by the stamping out of the lugs C C are indicated by the letters D D.
It is obvious that the form of the upper portion of the rail used is not material, as the chair is adapted to seat many forms of rail.
Having thus fully described my said invention, I claim- A box-chair for railroad-rails, provided with diagonally-located lugs out out of the sides and bent over from the seat of the chair.
E. B. ENTWISLE.
