IMPROVED DIES FOR SWAGING HAMMERS.

Specification forming part of Letters Patent No. 70,997., dated November 19, 1867; antedated October '22, 1867.

To all whom it may concern:

Be it known that I, HENRY HAMMOND, of Hartford, in the county of Hartford and State of Connecticut, have invented a new and useful Improvement in Making Elongated Sockets in Hammers and other tools; and'I do hereby declare that the following is a full, clear, and exact description thereoflreference being had to the annexed drawings, and to the letters of reference marked thereon.

Figure 1: A shows a horizontal and B a side view of die No. 1 for making hammers. Fig. 2: A shows a horizontal and B a side view of die No. 2, with the hammer and bar out of which it is struck. Fig. 3: A shows a horizontal and B a side view of die N o. 3. Fig. 4: A shows a horizontal and B a side view of die No. 4, with the hammer inclosed.

My invention consists in making and forming hammers and other tools having an elongated socket or eye for the insertion of the handle by means of punches or dies, in such a manner that the elongated socket is formed wholly or partially out of the material punched out of the eye, whereby a great saving is effected over the usual method of strikin g or forging the tool solid, and afterward drilling or punching the eye.

The following description of the manner of making hammers will enable others skilled in the art to make and use my invention.

The bar a, Figs. 2 and 4, of which the hammer is made is of the size and section of the main body of the tool, or nearly so, independ ent of the elongated socket 5 shown in the figures. This bar is first placed in die No. 1,

which gives the general shape to the hammer, and, by means of the punch c, strikes the metal out of the bar, forming the projection I), and

partially forming the eye. The tool is then passed through an ordinary trimmer to remove the burr. It is next placed in die N o. 2, which splits the claw by means of the knife 01, and also deepens the hole of the eye, so that but a thin shell is left at the end of the projection that is to form the elongated socket.

claws to the proper curve, and also finishes the hole for the eye by means of the punch c, which passes entirely through the tool, cutting out a small piece of metal. which passes through the opening g. The cutter fin the die, through which the punch 0 passes, is shown removable in the figure. The tool is next placed in die No. 4, which acts as a swage to give it its final form and finish. The two punches c and 0 enter the eye and give it the proper form, enlarging it slightly, as is usual,

at the ends. After leaving this die the hammer is removed from the bar a.

The above description will also show the manner of constructing any other tool having an elongated socket. It is intended to show how the socket can be formed while the tool. is being completed in other respects.

The socket above can be formed by one die or more, as might be found most convenient in different cases.

What I claim as my invention, and desire to secure by Letters Patent, is

The peculiar manner of constructing hammers herein set forth, by means of dies and punches of the form described.
