UNITED STATES PATENT OFFICE.
CHARLES` PARKER, OF MERIDEN, CONNECTICUT.
IMPROVEMENT IN CLAW-HAMMERS.
Specification forming part of Letters Patent No. 151,907, dated June 9, 1874; application tiled April 2, 1874.
To all 'whom it may concern:
Be it known that I, CHARLES PARKER, of Meriden, in the county of New Haven and State of Connecticut, have invented a new Improvement in Claw-Hammers; and I do hereby declare the following, when taken in connection with the accompanying drawings and the letters of reference marked thereon, to be a full, clear, and exact description ofthe same, and which said drawings constitute part of this specification, and represent, in
Figure l, a sectional side view; Fig. 2, a rear view; and in Fig. 3, the claw-face detached.
This invention relates to an improvement in what are known as olaw7 or joiners7 hammers, and particularly to those which are made from cast-iron.
- In this class of hammers the inner edge of the claw is liable to break away in drawing nails.l The object of this invention is to prevent this breaking away of the claw; and it consists in the introduction of a steel face to the claw secured in the process of casting.
A is the head 5 B, the eye; C C, the claws,
of substantially the usual form. rlhe mold for casting the hammer is prepared in the usual manner, and prior to pouring the metal a piece of steel or other suitable wrought metal, a, is laid into the mold on the face of the claw part. This piece is preferably slit and formed substantially as seen in Fig. 3, the slit opened corresponding to the claw. The metal flows around this piece, and firmly secures it to the face of the claw. The hammer is then finished in the usual manner, the claws presenting a wrought-metal face. o
The edge of the piece should be beveled so as to lock under, as shown, or otherwise prepared to engage with the cast metal.
The claw-face may be tempered the same as in a solid steel hammer.
I claim as my invention- A cast-metal hammer with wrought-metal face a, attached by the process of casting, substantially as specified.
CHARLES PARKER.
lVitnesses GEORGE C. MEREIAM, RALPH A. PALMER.
