IMPROVEMENT IN SOFT-METAL HAMMERS.

Specification forming part of Letters Patent No. 146,989, dated February 3, 1874; application tiled December 3l, 1873.

To all whom fit may oncern:

Be it known that I, JEHIEL C. GOBURN, of the city and county of l/Vorcester and State of Massachusetts, have invented a certain new and useful improvement, viz., a Soft- Metal Hammer; and I hereby declare the following to be a full, clear, and eXact description of my invention, sufficient to enable other skilled artisans to make and use the same, reference being had to t-he accompanying drawings, which forma part of this specitication, and in which- Figurel represents a side view of a softmetal hammer made in accordance with my invention. Fig. 2 represents a central longitudinalsection of the same at line x x, Fig. l; and Fig. 3 represents a transverse section at line w fw, Fig. 1.

This invention relates to an improved manner ot' preparing babbitt-metal and similar soft lnetal for market; and consists in casting the metal into the form of amallet or hammer, with the handle and head entire in a single piece, the handle being re-ent'orced or stren gthcned by a rod of steel or iron through its center, as hereinafter described.

In the drawing, A denotes the head, and B the handle, both otl which are cast in a single piece, and at the same time, in a mold ot' proper Jr'orm, a bar or rod, C, of iron or steel, being iirst placed in the mold in such position that it will form a central core to the handle B, as shown, extending from the front of the head to the rear end of the handle. Portions of the bar may be flattened, as indicated at c c, to prevent the ba-r from being drawn out or becoming loose when the hammer is put to severe use 5 also, when cooling, the metal contracts and hugs closely around the bar, so that said bar is very firmly bedded and secured in place. The bar C renders the handle B very stift and strong, and prevents it from bending or breaking at its junction with the head A.

The metal put up in these hammers is sold in place of the ordinary ingots or pigs, and, when the hammers have become battered or broken, can, as pigs, be melted up for other uses. The cost ot' the metal when put up in this manner is not necessarily greater than when sold in ordinary-shaped pigs, so that the shops can be furnished with good soft-metal hammers at a very little or no extra expense over the cest of their metal when furnished in the ordinary form. It will thus be seen that, without detraetin g in the least from the value of the pig metal, it is made additionally useful at no appreciable additional expense.

Il y making the handle Vand head in a single piece, the cost of a wood handle, which would otherwise'be needed, is saved, while the weight of metal as a pig is greater than with simply a head.

I-Iaving described my invention, what I claim therein as new, and desire to secure by Letters `Patent, as au improved article of manufacture,

A soft-metal pig formed as a mallet or hainmer, the head and handle being cast in one piece, and re-entorced 0r strengthened by the rod C, substantially as herein set forth.
