PATRICK J. LAVELLE, OF J OHNSTOWN PENNSYLVANIA, ASSIGNOR TO THE JOHNSON COMPANY, OF SAME PLACE.

METHOD OF AND DIE FOR MAKING RAIL-CHAIRS.

SPECIFICATION forming part of Letters Patent No. 482,092, dated September 6, 1892.

Application filed February 2, 1892.

and useful Method of Making Rail-Chairs and Dies for the Same, which invention is fully set forth and illustrated in the following specification and accompanying drawings.

The object of this invention is sufiiciently indicated by the title above given to it.

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

In the accompanying drawings, Figures 1 I5 and 2 are elevations showing opposite sides of an upper die provided with a stampingpunch secured in its face. Fig. 3 shows said die in end elevation. Fig. 4 shows said die in bottom plan. Figs. 5 and 6 show opposite Fig. 7 shows said die in end elevation. Fig. 8 shows said die in plan. Fig. 9 is a View of the bottom die, similar to that shown in Fig. 6, on an enlarged scale, showing a chair inserted in Fig. 10 shows in side elevation the stamping-punch of the upper die in position above the lower die. Fig. 11 shows the finished chair ortie-plate in perspective.

In said figures the several parts of the dies 0 are indicated by reference-letters, and the method of making the chairs is as follows: A blank is first cut from a piece of angle-iron so as to leave the side lug or brace G, Fig. 11, in comparatively rough outline. This cut- 5 ting may be done in any suitable manner, as

by punching or otherwise. In this operation the brace G may be bent or set out of desired line or truth. Hence itwill be necessary to true up the chair by a succeeding operation,

which operation is performed as below described, advantage being taken at. the same time to effect the stamping up of the clip M on one side of the base of the chair. For this operation two dies are provided,an upper die 5 A and a lower die II. This lower die is secured to the block or anvil L of a drop-press or steam-hammer by a key or wedge K, and the top die A is secured in the drop or hammer head byadovetail or other or additional Serial No. 420,083. (No model.)

fastening. In said die A is inserted a faceplate or tool-holder 13, secured thereto by a key or wedge W, and in said face-plate is inserted and held by the bolt 1) a punch and stamp D, as clearly shown in Figs. 1., 2, 3, and 4. In the lower die His inserted a face-plate N, secured thereto by a key or wedge 71, and in said face-plate is formed a recess 0, in which is also formed a depression or pocket e, Fig. 5. The edges of this pocket e are shaped to give a punching-edgefor the stamping-punch D to cut a corner from the clip M. (Clearlyshown cut off at the pointM, Fig. 11.) The rest of the clip M is stamped into the recess C by the stamp D, as shown in dotted lines d, Fig. 9. In said Fig. 9,the chair-blank c is shown inserted, bottom up, having its brace part G on one side of the lower die, so that the inclined side of the brace rests on the inclined side 1' of the guide or plate I, bolted to one side of the die H by the bolt Z9 and its straight edge rests against the side edge of the plate E, bolted to one side of the die H by the bolts 19'. The plate I is supported in the slotl and is made adjustable by being itself provided with a slot 5, through which the bolt 1) passes, having on its end a nut 91 for clamping said plate, as clearly seen in Fig. 9. The plate F is secured to the side of the lower die H by the same bolts b which secure the plate E. It can now be readily understood that upon bringing the upper die down upon the blankcin the lower die the blank will be trued up between the dies, the brace G being forced between the plates I and E, and by the same stroke the clip M is formed and cut to shape by the punching-stamp D, the heel of which stamp is rounded or cut away, so that the clip M is not cut off, but remains at one end intact and connected to the chair. This operation con verts the blank of wrought metal into a complete chair all at one heating and by the use of but one hammer or drop-press. While the dies are shown operating upon the rail-chair with the brace downward, it is evident that the dies can be reversed and the chair operated upon with the brace upward without depasting from this invention.

Having thus fully described my said invention, I claimv 1. The method of fabricating a rail-chair of the form substantially as hereinbefore de- 5 scribed, which consists in first cutting out a side lug or. brace fromapiece of angle-iron to form a blank for the chair and then truing up said lug and stamping up a clip indies to complete the chair.

:0 2. A pair of dies for forming rail-chairs,

consisting of a die provided witha punch, as D, and amating die provided with a depression suited to the shape of said punch in performing its office and with a guide for truing up a side lug or brace on the chair.
