Description

W. A. DARLING.
CUTTING BLADE ATTACHMENT.
APPLICATION FILED NOV. 1. 1919.
Patemed Nov 16, 1920:.
UNITED STATES PATENT OFFICE.
WILLIAM ARTHUR DARLING, OF KANSAS CITY, MISSOURI.
CUTTING-BLADE ATTACHMENT.
a simple and inexpensive cutting blade attachment for hammers such as are used by carpenters and similar mechanics, the blade being eifectively attachable without supplemental fastening means so that it may be used at a moments notice when required and yet when not needed will not obstruct the ordinary use of the hammer or interfere with the operation thereof in the perform- ,ance of its ordinary functions; and with these objects in view the invention consists in a construction and combination of parts of which a preferred embodiment is shown in the drawing, it being understood that changes in form and proportion may be resorted to within the scope of the claim without departing from the principles involved.
In the drawing:
Figure 1 is a side view of the blade attachment embodying the invention applied in the operative position to a hammer head.
Fig. 2 is a similar view of the attachment disconnected from the hammer head.
Fig. 3 is an edge view to show the hammer head seat and the lug for engaging the claw of the hammer.
Fig. 4 is a detail sectional view on the plane indicated by the line 4 4c of Fig. 1.
The attachment consisting essentially of the blade 10 is adapted for attachment to an ordinary hammer head shown at 11 and provided wth the usual claw 12 which is bifurcated to form a nail extractor. Said blade is provided with a segmental seat 13 adapted Specification of Letters Patent. Patented N 16, 1920,
Application filed November 1, 1919.
Serial No. 335,007.
to fit and receive the exterior convexed surface of the claw of the hammer head bearing uniformly thereon from the extremity of the claw to a point preferably beyond the line of the eye, and adjacent to the base of the hole 15, so that said seat has a bearing both longitudinally and transversely with reference to the hammer head. Located in the seat at one end opposite the blade is a lug 16 which is undercut at its sides as shown at 17 to receive the inner edges of the members 18 of the claw atopposite sides of the tapered slot or opening formed therein.
Said lug is also tapered longitudinally so as to substantially occupy the entire length of the opening representing the bifurcation of the claw. Therefore in use, or when the cutting blade is being employed as an attachment to the hammer head, the possibility of displacement is reduced to the minimum, and the weight and strength of the hammer head are disposed-in a column corresponding with the length of the cutting blade to ren der the latter substantially as efficient as a hatchet blade wherein an integral connection is made between the blade portion and the head of the implement. Obviously the attachment can be dismounted simply by sliding the same in the direction of the curvature of its seat to remove the lug from the bifurcation of the claw.
