RAILROAD-RAIL CHAIR AND PROCESS OF MAKING THE SAME.

SPECIFICATION forming part of Letters Patent No. 482,804, dated September 20, 1892.

Application iiled september 30, 1891. Serial No. 407,277. (No model.)

To all whom it may concern.-

Be itknoWn that I, ARTHUR J MOXHAM, of Johnstown, in the county of Oambria and State of Pennsylvania, have invented a new and useful Railroad-Rail Chair and Process of Making the Same, which invention is fully set forth and illustrated in the following specification and accompanying drawings.

The object of this invention is to partly form a rail-chair preferably by rolling and then to complete the blank so formed by subsequent treatment.

The invention will first be described in detail, and then particularly set forth in the claims.

In the accompanying drawings, Figure 1 shows in cross-section the appearance of the metal blank for the chair at one stage of the process herein described. Fig. 2 shows in cross-section the appearance of the blank at an advanced stage of the process. Fig. 3 shows in cross-section the complete chair having a girder-rail seated thereon. Fig. l shows the chair in side elevation uniting the ends of two contiguous rails.

In the figures the several parts are respectively indicated by reference-letters, as folows:

The letter R indicates a side-bearing girder-rail; H, its head; T, its side tram; w, its web, and F its lower flanges.

The letter B indicates the brace portion of the chair; 0, its vertical sides; f, its lower flanges; h, holes in said flanges for securing the chair in place, and s the rail-seat for the rail R. The brace B is shaped, as shown at e, to fit over the lower flange F of the rail, and is also preferably shaped, as shown at a, to fit under the head of the rail. On the side opposite the brace B the rail is shown clamped to the chair by means of a clip and key 0, inserted in a hole in the rail-seat, though any other suitable device may be substituted therefor.

The process of making the chair, if rolling be the first step, is as follows: A hot bloom ingot or bar of metal is first rolled into the box form shown in Fig. 1, having alump or protruded mass of metal L on its upper surface. ably under a hammer, to assume the shape of the portion'B. (Shown in full lines in Fig. 2.) Said portion B is then bent or formed by anysuitablemeansintothe rail-brace. (Shown in dotted lines in Fig. 2 and in full lines in Fig. 3.) If the chairs are rolled in long lengths, said lengths may be cut up into the lengths of chairs required either before or after the drawing out above described.

Instead of rolling a blank of metal with a lump L, as shown in Fig. 1, the upper surface of said blank may be rolled into the shape indicated by the dotted line b and said surface then drawn out in a manner similar to that described for treating the mass L, or, if desired, the brace portion B and one side C of the chair, Fig. 2, may be rolled, having a mass, such as L, on one side, and said mass then drawn or forged out to form the railseat 3 and the other side 0 and footf of the chair. The shape of the lower portion 0 C ofthe chair is immaterial, and the brace portion E may also be varied in shape without departing from this invention. It is obvious that by this process the chair maybe shaped to seat many other forms of rail than that shown in the drawings and to fit the different forms of rail required.

While the initial shaping of the blank is preferably and most feasibly or cheaply effected by rolling, it is obvious that such form may be imparted to it by other suitable meohanical means-such, for instance, as by forging, casting, or cutting, depending upon the nature of the metal employed.

Having thus fully described my said invention, I claim- 1. A rolled blank for making rail-chairs having an excess of metal on one of its surfaces adapted to be drawn out to form a portion of the finished chair.

2. The process of making rail-chairs, consisting in first forming a bar of metal into part of the shape of chair desired, and then drawing out a portion of said bar to form the remainder of the chair.

3. The process of making rail-chairs, consisting in first forming a bar of metal into Said lump is then drawn out, preferv its upp r surface, and then drawing out said protrusion to form a mil-brace ARTHUR J. MOXI-I'AM. Witnesses:
