CARL KNOPF, OF NEW YORK, N. Y.

MALLET.

Specification of Letters Patent.

Patented Aug. '13, 1907/ Application filed May 2, 1907. Serial No. 371,427.

To all whom it may concern:

Be it known that I, CARL KNOPF, a citizen of the United States, and a resident of the city of New York, (borough of Brooklyn,) in the county of Kings and State of New York, have invented a new and Improved Mallet, of which the following is a full, clear, and exact description.

This invention relates to certain improvements in mallets especially adapted for use of workers in soft metal, as, for instance, tinsmiths, coppersmiths, and the like.

The object of the invention is to provide a double faced mallet having the head formed of two separate pieces of non-metallic material, as, for instance, wood, so constructed that they are rigidly held in place by the insertion of the handle, and so formed that the metallic inclosing sheath or casing cannot come in contact with the article being pounded into shape by the mallet.

The invention consists in certain features of construction and combination of parts, all of which will be fully set forth hereinafter and particularly pointed out in the Claims.

Reference is to be had to the accompanying drawing forming a part of thisspecification, in which the figure illustrated is a central longitudinal section through a device embodying my invention.

In my improved mallet, I provide a hollow openended casing having the two oppositely disposed members going to make up the head, rigidly secured therein by means of the handle. The sheath 0r casing 10 is preferably formed of metal and may be cylindrical in form, or provided with slightly divergent ends and contracted intermediate portion, as illustrated in the drawings. This casing serves to support the two opposite members 11 and 12 which make up the head proper, each of these members being provided with cylindrical or somewhat tapered shank portions 13 extending into the opposite ends of the casing. Each of these shank portions terminates in a beveled or inclined face 14, and each shank extends a considerable distance beyond the center portion of the casing, the beveled or inclined face of one head member engaging with the corresponding face of the opposite head member. The intermediate portion of the casing is provided upon opposite sides thereof with openings, and the overlapping end portions of the head members are provided with corresponding openings adapted to be brought into alinement with the openings in the casing. With the two head members forced inward into the casing to the limiting position and properly disposed in relation to the casing, the openings are all brought into alinement to permit of the insertion of the end of the handle 15.

The inserted end is preferably slightly tapered, and the openings in the head members may, if desired, be slightly elongated to facilitate the wedging action and draw the head members into firmer engagement with each other and the surrounding casing. Each head member is provided with a curved face merging into a curved circumferential flange 16 of materially larger diameter than the casing 10. The surface of the flange merges into the surface of the shank portion, and due to the expanded nature of the ends of the casing and the wedging action due to the insertion of the handle, the head members may be drawn very firmly into engagement with the casing. By making the flanges 14 of larger diameter than the casing, it is practically impossible to bring any portion of the metal casing 10 into engagement with the material operated upon.

The mallet above described is particularly adapted for the use of tinsmiths, coppersmiths, and other workers upon metals malleable at ordinary temperature. In working upon these metals even a slight blow from an iron tool leaves a mark or blemish which is very difficult to remove. The flanges 16 of my improved mallet thoroughly protect the metal from the edges of the casing, as will be readily understood. As soon as the surface of either of the head members wears away to such an extent as to affect the efliciency of the tool the head member may be readily removed and replaced by a new one by simply removing the handle 15.

Having thus described my invention, I claim as new and desire to secure by Letters Patent:

1. A mallet, comprising a hollow cylindrical casing having open ends, oppositely disposed head members having shank portions extending into the ends of said casing. and a handle in engagement with the shank portion of each of said heads for holding the same within said casing.

2. A mallet, comprising an open ended casing, oppositelydisposed head members having shank portions extending into the ends of said casings, said shank portions being provided with transverse openings, and a handle extending through said openings and serving to hold said head members within said casing.

3. A mallet, comprising an openended casing, oppositelydisposed head members having overlapping inner ends, and a handle extending; through the overlapping ends to hold the head members.

4. A mallet, comprising an open-ended casing, oppositely disposed head members having overlapping inclined inner ends, said ends and easing having an opening there through and a handle extending through said opening and serving to hold said members and easing rigid in respect to each other.

5. A mallet, comprising an open-ended metallic casing having oppositely disposed head members, each havinga shank portion extending into said casing with a transverse opening through said shank and having an outwardly-extending flange adjacent the corresponding end of the casing, and a handle extending through the openings in said shank portions and through an opening in said casing for holding the head members and easing rigid in respect to each other.

G. A mallet, comprising an open-ended casing, head members having shank portions extending into said casing and having outwardly extending flanges adjacent the ends of the casing, the inner ends of said shank portions terminating in inclined surfaces overlapping each other and having an opening, and a locking member extending through said openings for locking the head members in 10 position.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

CARL KN OPF.
