`:cMPnovrua-M'rrrnrcna or' FORMING sTUMPgoINTs ron cARnIAGnBoWs.

The Shedule referred te in these Letters Patent and making part of the same.

I, ALBERT ROASEY, of Plantsville, in the county of Hartford andState of Connecticut, have invented new and useful ImprovementsinEorging the Joints of Carriage-Bows, of whichI the following is a specilication.V

n My invention consists in a series of dies'for forging stumpjoints forcarriage-bowsfrom a straightpieoe y of iron 0f ,the proper size for the bow.

`In the accompanying drawing.- `Figure 1 is a 'top view of the dies for the first 0p-A eration.

Figure 2, aside elevation ofa blank, formed by the dies iig. 1.A

n y Figui-e3, a view, partly in f section, of' the diesfor the second operation. l n l y Figure 4, avicwof the same, with `.the blank fig. 2

inscrted-previousto upsetting it; andf Figure 5 is a side elevation of a finished stumpjoint blank.` n n The diesA A, fig. 1, are arranged in'any suitable' press or machine, so'as t`o be readily opened and closed. In .the drawing, lthese dies are represented open.'

` t A straight piece of square iron, o f the size desired for the finished stump a of the joint, g. 5, is taken when hot and placed between, the dies A A, when the same are brought together, which offsets the iron C `into theform ofthe blank b,shown in iig. 2.

The iron maybe eut into'pieces of the proper length either before or after it is placed in the dies, as desired. u 1 n l n B designates a solid die, represented in section to' show its form, and which is used in connection with the dic'rB'. n n

The die Bi is `made in halves, so vas to open and `closetoreadily admit the blank b. Only one-half of the die B' is shown in the drawing.

The'dies B B are arranged in any suitable press or drop, so as toopen and close, and in the positions 'represented in iigs..3 and 4.

When still hot,-or when made so by a subsequent heat, the blank b is placed in the die B', as shown in iig. 4,A and clamped between its two halves, so as to hold it firm; or, if desired, a support may be furnishedA for its lower end to rest against.

The blank b being offset, its end is immediately under the die B, so as to enter the same as the dies B.

Bare brought together,'wbich upsets the blank b, and causes it t0 fill the dies, ands-thus giving it the requiredl form; l

The surplus metal which projects from the blank between the dies is then trimmed o, and the stump- `jointis ready to finish, as shown in 5.

By properly gauging the iron when offset by the die-s A'A, the amount of surplus metal on the blank,

when taken from the diesB B', will be very small.

Ordinarily, stump-joints and similar articles have been forged by drawing out the stump'of the joint vfrom large iron, and leaving a portion of the full-sized iron t0` be forged into the joint.

less labor, `and consequently at less cost.

I claim as my invention- The method of forging the stump-joint for carriager By my invention, the article is forged with much bows,-`herein described, bysubjecting a straight pieceV f iron,` of the sizeof .the finished stump ot' the joint, tothe series of dies which offset and upset-the iron into the' required form, substantially as described.
