V H. CHRISTENSEN HAMMER AND HANDLE ASSEMBLY Filed Nov. 29 1921 Patented Sept. 16, 1924.

rscasre HANS CHRISTENSEN, OF GOLDEN, COLORADO.

HAMMER AND HANDLE AssEMBL-Y.

7 Application filed November 29, 1921. Serial No. 518,534.

T 0 all whom. it may concern:

Beit known that I, HANS CHRISTENSEN, a citizen of the United States, residing at Golden, in the county of Jefferson, State of Colorado, haveinvented certain new and useful Improvements in Hammer and Handle Assemblies, of which the following is such a full, clear, and exact description as will enable others skilled in the art to make and use the same, reference being had to the accompanying drawings, formlng a part hereof.

The object of the invention is to provide positive and efiicient means for retaining a handle on a hammer head and reinforcing the handle to prolong its life.

Briefly the invention comprises a metallic strip interposed between the handle and the head within the socket of the head, so as to wedge the handle within the socket; said strip preferably has means for positive retaining engagement both with the head and the handle, although in certain forms the latter may be omitted.

In the drawings, wherein certain embodiments of the invention are disclosed:

Fig. 1 is a view partially in side elevation and partially in section showing one form of retaining and reinforcing strip;

Fig. 2 is a similar View of a different form;

Fig. 3 is a like view of a form similar to that of Fig. 1;

Fig. 4 is a perspective View showing details of the form of Fig. 3;

Fig. 5 is a perspective view of the retainer of Fig. 2;

Fig. 6 is an end view indicated by line 66 of Fig. 3; s

Fig. 7 is a sectional View of a further modification Fig. 8 is a perspective view of the form of stripof Fig. 7,

In the drawings there is shown an ordinary hammer handle 9 and head 10, the head being provided with a socket 12 for reception of the handle. In those forms of the invention shown, except that of Figs. 2 and 5, either certain opposite walls of the socket 12 may converge slightly in the usual manner as indicated, or all opposite socket walls may be parallel, as may seem more desirable.

The retaining straps of all forms lie on both sides of the handle preferably, and between the handle and the walls of the socket.

In the forms of Fig. 1 and Figs- 3, 4 and 6, the retaining and reinforcing strapsor strips 14: are elongated, the inner. or handle end of each strap extending beyond the head and along the handle where it is enlarged at 16 and, shaped to the handle. A rivet or bolt 18 is passed through both the straps and the handle and retains the parts in operative relation. The outer orhead end of the strap of Fig.1 is shaped to provide a retaining bead'or lug 15 which engages the head 10, while in the form of Figs. 3, 41- and 6 said outer end is provided with beveled ears 20 adapted to rest upon corresponding countersunk shoulders 22 in the hammer head whereby a smooth exterior is presented at the outer end. The lugs 15 and ears 2O prevent. withdrawal'of the straps 14- from the socket and the bolts 18 prevent withdrawal of the handle from the straps.

In the form of Figs. 7 and 8, straps 30 are employed and these are provided with head-engaging lugs 32, handleengaging teeth 34, and rounded lips 35 rolled against the extension of the hammer head at the inner side thereof. The lugs 32 prevent withdrawal of the straps and the teeth 34 prevent withdrawal of the handle.

In the form of Figs. 2 and 5, the retainer is generally U-shape and comprises a base 25 to engage the end of the handle, legs 26 to be positioned between the handlev and the,

walls of the socket, and rounded or rolled head-engaging lips 28 similar to lips 35. In this form the walls of the socket must converge slightly, as in the usual head construction, in order to insure retention which is by reason of the convergence.

All forms may be assembled by first placing the retainer in the head and driving the handle into position, the portions which project beyond the head, including the rounded or rolled lips 28 and 35, serving to guide the handle and revent peeling up of the wood thereof as t e same is driven into position. This last mentioned feature of construction is important inasmuch as it permits ready driving of the handle so that the end thereof will expand into the larger part of the socket after compression by the lips 28 and 35 and the extensions of the form of Fig. 1. Even if the walls of the socket be parallel as above indicated, the construction described produces compression and insures a snug fit. If necessary, the tip of the handle may first be soaked slightly so that the same will yield a little more readily under the compressive influence.

In the form of Fig. 7, the straps may be driven in after the handle is positioned, the lips 35 being rolled afterwards with a tool.

All forms are retainers, but the forms of Fig. 1 and Figs. 3, 4: and 6 serve the additional function of reinforcing the handle during use, thus permitting the application of greater strains during use and insuring greater life of the handle.

I claim:

1. In combination, a hammer head having a socket tapering from its outer face inwardly whose front and rear walls eX- tend transversely of the length of the head, a handle positioned in said socket having its socket end tapered as is said socket, and separate retaining straps positioned between said front and rear walls and the front and rear sides of said handle, the outer ends of said straps having means for positively engaging said head and terminating within the outlines of the outer face or" said head,

said straps having means for positively engaging said handle the grip portion of the handle being too large to pass through said socket.

2. In combination, a hammer head having a socket tapering from its outer face inwardly whose front and rear Walls extend transversely of the length of said head, a handle in saidsocket having its socket end tapered as is said socket, and retainer straps positioned between opposite sides of the handle and said front and rear walls, said straps having a width at least equal to that of said walls where the straps leave said socket whereby said straps serve as guides for driving the handle into the socket, said straps having means engaging the head to prevent withdrawal therefrom and means engaging said handle to prevent withdrawal thereof the grip portion of the handle being too large to pass through said socket. In testimony whereof, I afliX my signature.

HANS CHRISTENSEN.
