HAMMER Filed Oct. 18, 1946 Patented Nov. 29, ,1949
UNITED STATES PATENT OFFICE HAMMER Kenneth R. Wyllie, Port Huron, Mich. Application October is, 1946, Serial No. 704,189
1 Claim.
This invention relates to hammers and more especially to a soft-faced metal striking hammer for use in work on jigs, fixtures, patterns, and machinery in general, where a soft head is necessary to prevent damage to the equipment.
One of the prime objects of the invention is to design a hammer having a quickly detachable head so that excessively battered, distorted, or frayed striking heads can be easily and quickly removed and a new head clamped in position.
Another object is to provide a hammer including readily operable clamping means for firmly securing the head in position, which will remain tight in use, and which can be readily and economically manufactured and assembled.
A further object still is to provide a detachable head hammer of simple construction which will be strong and durable, yet capable of being produced of relatively inexpensive materials and with few operations.
With the above and other objects in view, the present invention consists in the combination and arrangement of parts, hereinafter more fully described, illustrated in the accompanying drawing, and more particularly pointed out in the appended claim, it being understood that changes may be made in the form, size, proportion, and minor details of construction, without departing from the spirit or sacrificing any of the advantages of the invention.
In the drawing:
Fig. 1 is a side-elevational view of the hammer with the head clamped in position.
Fig. 2 is a top plan view thereof.
Fig. 3 is an enlarged, detail side-elevational view of one of the head clamps.
Fig. 4 is a detail side-elevational view of the hammer head.
The instant invention is to design a hammer handle from which a battered hammer head can be easily and quickly removed and a new head replaced, so that these battered heads can be remelted and again cast to shape, thereby effecting a substantial saving in material, the handle being used over and over again.
It is, of course, obvious that better work is accomplished with good tools, and the fact that battered heads can be quickly and easily removed and replaced with new heads will be conducive to the workmans using a good symmetrical head at all times.
Referring now to the drawing, the numeral 8 indicates the handle of the hammer. This is preferably formed of metal, either hollow or solid, an enlarged grip 9 being provided on the one end as shown, the opposite end terminating in a shank section Ill, internally threaded, as at II, to accommodate a pair of head clamping members C, as will be hereinafter more fully described.
The hammer head H can be made up of lead, copper, wood, plastic, rubber, rawhide, or any other suitable material and is formed as clearly shown in Fig. 4 of the drawing, the center section being formed or cast with a groove H of predetermined width to accommodate the curved sections l3 of the clamps, the edges of the groove being chamfered as at 14 to facilitate the assembly.
The inner faces of the curved sections I3 of the clamps are of the same diameter as the grooved section I2 of the head, and the inner ends of the clamp sections are formed half-round and threaded as at [5, so that when the clamps are clasped in the groove of the head, the fiat sections l6 of the clamps are disposed in facial contact, forming a cylindrical assembly which can be readily threaded into the threaded section II of the handle, and thereby firmly securing the head in position, it cannot fly off the handle as frequently occurs with the conventional hammer, and it can be utilized for any desired purpose.
It will be noted that the free ends of the curved section do not contact each other when assembled, and the extreme ends are preferably tapered as at H to present a neat finished appearance.
My construction permits the salvaging of the battered heads representing great savings in production shops where many hammers are used, and likewise conserves handles which are usually discarded with the heads, as one handle can now be used for a great number of heads.
From the foregoing description, it will be obvious that I have perfected a very simple, practical, and inexpensive hammer in which the head is readily removable and replaceable.
What I claim is:
A detachable head hammer of the class described, comprising, a hollow handle member having an enlarged, internally threaded shank on facial contact to form a cylindrical body for detachable threaded engagement with the threaded opening in the shank end of the handle to securely 1o clamp the head in position thereon.
KENNETH R. WYLLIE.
