L/ /1- SZOUGH ATTORNEY United States Patent 3,355,226 STRIKING IMPLEMENTS William E. Portz, Geneva, Ohio,.assignor to True Temper Corporation,'Cleveland, Ohio, a corporation of Ohio Filed May 11, 1966, Ser. No. 549,290 8 Claims. (Cl. 306-32) My invention relates to striking implements and relates more particularly to striking implements of the type having a head of metallic material and a handle of nonmetallic material, and relates more particularly to an improved connection between the head and the handle, and the method of assembling the same,

While my invention is preferably 'ap'plied to h'and tools, such as hammers, etc., it will be evident, as disclosed in one modification illustrated herein, that the same may be applied to a striking implement of the so-called golf club type, or like implement.

It is an object of the present invention to provide secure mounting of a non-metallic handle or shaft 'in a socket in a head such as a hammer head or golf club head wherein the handle or shaft is firmly bonded 'to the head of the tool or club respectively.

Another object of 'the present invention is to provide improved means for guiding a handle or shaft into secure engagement within a socket of a'tool or club of the type referred to, said guide means also functioning to direct adhesive or other bonding means into contact with certain portions of the walls of the said socket and into contact with certain portions of the end of the handle or shaft adjacent thereto.

A still further object of iny'invention is to provide improved means in said handle or shaft for anchoring end portions of the said handle or shaft in the head of the tool or club, etc.

A still further object of my invention is to provide an improved striking tool of the type referred to generally herein which is economical in construction, easily assembled, and highly efficient and durable in use.

Other and further objects of my invention and the invention itself will become more readily apparent from a review of the description and claims appended hereto, in which description reference is made to the accompanying drawings, forming a part thereof, wherein:

FIGURE 1 is a fragmentary longitudinal section of the structure of my invention as applied to a hammer;

FIGURE 2 is a sectional view taken on the line 22 of FIGURE 1;

FIGURE 3 is a fragmentary sectional view taken on line 3-3 of FIGURE 2;

FIGURE 4 is a fragmentary sectional view taken on lines 44 of FIGURE 2;

FIGURE 5 is a transverse sectional view taken on line 5-5 of FIGURE 5;

FIGURE 6 is a fragmentary sectional view of a modification of my invention as used in the hosel end of a golf club shaft;

FIGURE 7 is a perspective view of means used in the embodiments of FIGURES 1 to 6, inclusive; and

FIGURE 8 is a view similar to FIGURE 1, adhesive or the like being omitted from the showing for clarification.

Referring now to the drawings, in all of which like parts are designated by like reference characters, a hand tool embodying the invention is disclosed in FIGURES 1 to 5 which, in the form shown therein, is a claw hammer generally comprising a hammer head or striking element 10 and a handle 11. The hammer head 10 has the usual poll and bell 12 and claws 13 at opposite ends thereof and a medial portion 14 having a closed end handlereceiving socket 15 formed therein. The said socket in the form disclosed is provided with a generally V-shaped 3,355,226 Patented Nov. 28, 1967 socket end wall 16, longitudinally extending side walls 17 of any desired form, cylindrical, circular, tapered, etc. The said socket 15 is adapted to receive an end portion 30 of the handle 11 and serves as a reservoir, as Well, for epoxy or other adhesive material. When the handle 11 of the tool, preferably formed of non-metallic material, as for example, fiber glass, plastic, wood, etc., is driven into the socket, displacement of part of the epoxy disposed in the socket occurs, the same being forced into spacing provided between the side walls of the socket and the outer periphery of the socket received end portion of the handle. It will be observed that the said end portion of the handle is formed substantially complementary in shape to the socket. In the form shown the socket and socket received end of the handle are generally of cylindricalform and gradually tapered from the ingress portions 31 towards the tip end of the handle. To provide spacing between the handle and the head of the tool, the diameters of the socket inserted portions of the handle are slightly less than the diameters of the socket within which the said end portions of the handle are inserted wherefor a slight clearance exists therebetween, as will be evident from the drawings and appended description.

A spider 22 is adapted to be disposed over the end portion 30 of the handle 11 of the tool. Said spider consists of a pair of

wires

23, 24 intersecting each other, as best shown in FIGURE 7, the intersecting portions 23', 24, being disposed preferably flatwise over a flattened end face 31 of the handle or shaft. A pair of elongated depending

legs

25, 26, 25, 26' of the said

spider wires

23, 24 respectively, are disposed over opposite sides of the handle 11 and are adapted to lie within longitudinal areas of the space provided between the handle and the socket walls. The legs of said wires terminate in

ends

27, 28, 27, 28, respectively, which are adapted to extend outwardly of the eye portion of the socket to be retained in secure seating engagement against portions of opposite sides of the handle by a ferrule 29, preferably formed of metal, plastic, or other desired material. The ferrule 29 is adapted to abut the lowermost annular peripheral surfaces 35 surrounding the ingress end or eye of the socket 15 of the head 10 of the hammer.

The spider 22, it will be noted, is resilient and acts as a centering device for the handle, its legs acting as dividers confining the displaced adhesive or epoxy within longitudinaliy extending bonding areas between the end portions 30 of the handle and the inner walls of the socket 15 when the end of the handle having the ferrule retained spider thereon is inserted into the epoxy or other adhesive containing socket of the head. The head of the implement is thus adhesively secured or bonded to the handle by a plurality of longitudinally extending bands or strips 41- 41 and frictionally or mechanically secured thereto by the longitudinally extending

spring legs

25, 26, 25', 26 of the spider interposed therebetween.

I The handle 11, may as shown, further be provided with a plurality of transverse grooves 40 adapted to carry adhesive, etc., for further anchoring or bonding of the head to the handle.

In assembling the handle, the head 10 which is provided with a closed end 14 is preferably seated on its uppermost flattened end with the socket opening disposed upwardly; epoxy or other adhesive of pre'determined amount is placed in the socket opening; the handle, such as the fiber glass handle of the type shown, having a spider clamped thereon by means of the ferrule 25 is inserted into the epoxy, etc., containing socket, the legs of the spider act as a centering means for the handle and as guides for the adhesive, etc., which is displaced from the bottom of the socket and dispersed about the inner walls of the socket and the thereby spaced longitudinally extending portions of the handle.

In the form of my invention shown in FIGURE 6, the striking implement is a golf club; and in the form shown is provided with a metal head 100 having a shank 101, the shank being provided with a hose 102 into which a shaft of fiber glass or other preferred material is inserted. According to the invention, a ferrule or adapter 104 secures a spider 105 over the end of the shaft similarly to the placement of the spider over the end of the handle of the tool according to FIGURES 1 to 5, 7 and 8, and said spider 105 serves as a centering device for the shaft and secures the shaft in the hosel as by adhesive, epoxy, etc., means similarly to the structure described hereinbefore and disclosed in the said other figures of the drawings.

Although I have described my invention in connection with certain preferred embodiments, I am aware that numerous and extensive departures may be made therein, such as, for example, in the shapes or dimensioning of the handle or shaft and shape or dimensioning of the socket, without, however, departing from the spirit of my invention and the scope of the appended claims.

What I claim is:
