Patented Feb. 1, 1944 UNITED STATES PATENT OFFICE HANDLE EYE CONSTRUCTION OF TOOLS Ludwig Schwarzmayr, San Francisco, Calif.

Application May 15, 1943, Serial No. 487,412

1 Claim. (Cl. 145-29) One object of the invention is to provide tools with a handle eye construction which facilitates quick replacement of a broken handle, which is of great advantage when the old handle breaks in the performance of work, which very' often happens when pulling big nails with a clawhammer.

Another object is to more firmly mount the handle in the tool, which is very desirable in striking tools, such as an axe or a hammer.

I attain these objects by the handle eye construction illustrated in the accompanying drawing in which- Figure 1 is a sectional view of the handle eye construction of the invention in conjunction with a claw-hammer.

Fig. 2 is a sectional view of the handle eye construction of the hammer of Fig. 1 with a handle mounted therein.

Fig. 3 is a section of the handle eye construction of the hammer on line 3-3 in Fig. 1.

Fig. 4 is a sectional view of the handle eye construction of the invention in conjunction with an axe.

Fig. 5 is a sectional view of the improved handle eye construction in conjunction with a sledgehammer.

Fig. 1 shows a claw-hammer l, the body 2 of which ha a handle eye 3 constructed in accordance with my invention. The walls 44 of the intermediate section 5 of the eye 3 are parallel to the longitudinal axis 6 of the eye 3. The handle entrance 1 of the eye has walls 88 which are deflected outwardly from the walls 4-4, and on the ends of the deflected walls 88 are cutters 9, which, as is shown in Fig. 2, cut surplus wood Ill-l from the handle II when the handle is forced into the eye. In the upper end section l2 of the eye the walls l3l3 are slightly deflected outwardly from the walls 4-4. When mounting a handle in the eye of the tool body the leading end 14 is shaped to be received by the handle entrance I, and when the handle is forced into the constricted section of the eye the deflected walls 8B compress the wood of the handle, thereby a greater quantity of wood is caused to enter the eye of the tool than does in handle eyes of common construction, and consequently the handle is mounted more firmly in the body of the tool. To further secure the handle more firmly in the body of the tool water may be applied to the end portion I4 of the handle and caused to flow into the spaces 15-15 formed between the deflected walls l3-l3 and the compressed wood of the handle. When the compressed wood absorbs the water in the spaces Iii-l5 it expands to its original dimension, whereby a head is formed without the use of a wedge, which is commonly used to form a head to prevent the tool body from sliding from the handle.

Fig. 4 shows the improved handle eye construction in conjunction with an axe, in section. The handle eye IS in the body 20 of the axe has an intermediate section 2| with walls 22-22 parallel to the longitudinal axis 23 of the eye, and from the walls 22-22 extend the outwardly deflected walls 2424. The handle entrance section 25 of the eye has walls 2626 extending from the sides 2222 in an outwardly deflected position, and on their outer ends are cutters 21, which project from the face 28 of the body of the axe, thereby facilitating the cutting of surplus wood from a handle forced into the eye. The dotted lines 29 show the position of a handle when mounted in the eye of the axe.

Fig. 5 shows the improved handle eye construction in conjunction with a sledge-hammer. The eye 30 in the body 3| of the sledge-hammer has an intermediate section 32 with walls 33-33 parallel to the longitudinal axis 34 of the eye, and the upper end section 35 has walls 3l3l outwardly deflected from the walls 3333. The handle entrance section 38 of the eye has walls 39-39 outwardly deflected from the walls 33-33, and on the ends of the deflected walls 3939 are cutters 4B, which project beyond the face 4| of the body of the sledge-hammer. The position of a handle when mounted in the eye is shown in dotted lines 42.

I claim:

In a handle eye construction of a tool, a tool body having an elongated eye, the walls in the intermediate section of said eye being parallel to the longitudinal axis of the eye, the walls in the handle entrance section of said eye being deflected outwardly from the first mentioned walls, and a cutter on the end of each of said outwardly deflected walls for cutting surplus wood from a handle forced into the eye.

LUDWIG SCHWARZMAYR.
