Description
UNITED STATES DEXTER XV. PARKER, OF MERIDEN, CONNECTICUT, ASSIGNOR TO CHARLES PARKEILVOF SAME PLACE.
IMPROVEMENT IN CLAW-HAMMERS.
Specification forming part of Letters Patent No. 147,427, dated February 10, 1874 ,2 application filed January 7, 1874.
.State of Connecticut, have invented anew 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 of the same, and which said drawings constitute part of this specification, and represent, in-
Figure 1, a side view 5 and in Fig. tical central section.
This invention consists in a hammer formed from a metal body cast upon a previously-prepared head inserted in the mold before casting, the body and head united by the irregular form of the head.
A is the hammer, of substantially the usual form; B, the head or face. This head is first formed from steel, with a projection, a, upon its upper surface. The mold is made of the form of the hammer complete; then the head B is `placed in the mold in the position it is to occupy, and the molten metal poured into the 2, a vermold ilows upon the upper surface of the head,
iirml y attaching it thereto, and the completed hammer is removed from the mold. The head may be tempered to the desired extent, the same as a steel hammer, and for general use the hammer is as good as a forged hammer, and is produced for about one-fourth the cost.
I have represented my invention as applied to claw-ham mers, but it may with equal facility be applied to some other classes of hammers.
I do not wish to be understood as broadly claiming :forming an article partly from cast and partly from wrought metal united by casting.
I claim as my invention- As an article of manufacture, the herein-de scribed hammer, constructed by placing in the mold a previously-prepared head, then pouring the met-al for the body into the mold, the body and head united by the irregular form of the head, as described.
DEXTER W. PARKER.
