METHOD OF ATIAC'HING A TOOL HEAD TO ITS HANDLE.

Application filed August 9, 1922. Serial No. 580,624.

To all whom it may concern: 5

Be it known that I, FRANKLIN HUBBARD BnLLows, a citizen of the United States, residin at lVorcester, county of Worcester, and tate-of Massachusetts, have invented certain new and useful Improvements in the Methods of Attaching a Tool Head to Its Handle, of which the following is a specification, V

This invention relates to a method of attaching a tool head to itshan'dle and more particularly to an improved method of constructing across-handled socket wrench hav- ,ing the socket member permanently secured to the handle in such manner as to prevent relative movement when in use.

The objects of my invention are to provide an improved form of cross, or T handle, for tools, more especially an improved form of handle for those wrenches used to engage automobile wheel demountable rim securing bolt-s or nuts, which will have a portion for one handed speed operation enabling spinning ofthe work when it is easy to turn, together with portions having greater leverage adapted for two handed operation when greater power is of aid in turning the V tion illustrated by the drawings, the 1111- work, which will effect an appreciable saving in the material, time andexpense necessary to the process of manufacture, which improved handle can be secured into the working member as it is formed to the improved handle shape without employing other parts than the working member and the handle, thus greatly reducing the cost and time of manufacture while providing a handle which is'of strong durable construc tion and of such shape as to be used to better advantage than'the present forms.

The present commonmethods of forming the cross handle and securing the socket member of a cross handle socket wrench to its. cross handle, is to form the steel rod or heavy wire used for the handle into a T shape by first bending a section of rod at right angles to a shank portion then don bling back the greater part of the said section upon the lesser part so that the doubled back part extends over and beyond the shank portion a distance equal to the length of the lesser part. Thevertical or shank part of this handle is then-secured to the socket portion by inserting its end into a hole in "the base of the socket then drilling a hole transversely through both the base of the socket and the handle, a pin being driven WQRCESTER, MASSACHUSETTS, A COR- through said hole and riveted therein so as to prevent turning of the handlein' the socket and to hold the socket firmly upon the handle. This method and construction involves an unnecessary amount of material, time and expense much of which is eliminated by my, method of construction. i

The accompanying drawings and description will serve to show one embodiment of my invention as applied to socket wrenches;

In the accompanying drawings like numerals indicate the same'parts throughout the several views; I

Figure 1 is a side elevation ofjthe improved form of socket wrench embodying my invention, with the socket member shown in vertical section; a

Figure 2 is a sectional elevation with parts broken away showing a simplified method of securing the improved handle in the socket member; I Figure 3 is a plan view taken from F ig-' ure 1, loo-king at the recess end of the socket member.

In the specific embodiment of the invenmeral 4 indicates my improved form of handle. Located at the middle of this handle is the metal socket member 6 with a socket recess 8 for engaging a nut, or the like, which is to be turned.

Generally the handle 4: is formed of a solid metal rod or heavy wire bent to the required shape. I bend the ends which protrude from the metal socket. member 6 'to substantially the shape shown so that the portions 5- -5 adapted for gripping in the hands, for power operation, are raised from the working plane ofthe socket member 6 and the hands of the operator are protected from injury due to contact therewith while still working to advantage for the purpose of turning the socket member 6 with the nut, or the like, which the socket me mber has engaged in its socket recess 8. It will be seen that these portions 55 are so separated from each other, by the depressed por tion which carries the socket member, that for fast operation, when little power is required, the operators hand "may conveniently grasp the socket member itself, or. the portions of handle directly adjacent thereto,

7 member 6 the metal? so same axis as" socket to spin the tool with its engaged work, the portions 5-5 exerting a flywheel efi'ect'to aid such spinning.

For the purpose of engaging the handle 4: the" socket member 6 has an opening 7 which is slightly larger than the handle 4 to permit the insertion of the handle before it is bent to the improved shape. After inserting the handle 4L in the socket member 6 the ends of the handle 4 are bent in a press or other suitable power machine, or maybe held in a: vise and bent manually to my improved shape.

Parts of the socket member 6 may be then forced into-the handle 4: by inserting a punch: into the socket recess 8 in the socket then by exerting force on this punch" the relatively thin wall between said socket recess 8 and the handle opening 7 is formed into projections forced into the walls of the handle 4: as at 9', in Figures 1 and 3',- this seeures the socket member rigidly upon: the handle without the addition of pins-,ibolts, or the like v and Without disfiguring the socket member 6;

In Figure 2-is' shown my preferred form of engagement between the handle 4 and the I socket member- 6. The socket member 6 in this case has an aperture 11,. on the recess 8 completely through the socket member 6', although it is not essential forthe purpose of the inyention that the aperture 11 extend entirely through the socket, an aperture 8- separated from the hole 7, by a wall of: metal being also utilizable in this embodiment of the invention. The opening 7 for receiving, the handle L, h'asfits axis at right angles to this aperture 11' and cuts through the remaining metal 01% the socket member 6. Opening 7 is thus divided:- into two sections 7'? and the handle 4: passes through one sectionfi', across the aperture 11, then through the remaining section: of the opening 7.- The bandle 11 is inserted in" the-socket member 6- and bent, preferably hy'the methods previously described' the portion of the handle l which lies within the aperture 11 is now unsupported and the forces which bend the portions of the handleexterior to soeket mem her 6, distort that portion ofthe handle 4t lying within this aperture 11 beyond its 1 elastic limit so: that its walls are-forced; and

permanently set, against the wail-lsof the opening 3' at points lO-1 0 10'- 1O binding tigl-itly together that socket menmher (dis securely heldagainst any movement on: the-- handle 4- Without other fastening means the: handle 4. to-the socket 6' against relative movement consists" in bending or distorting the: portion@ of the ha rdle t which lies with hr the aperture 1 1,-

2, by pressure applied directlyto the said portion through the socket opening either before or after Another method of attachingthe bending of the exterior portions or simultaneous therewith.

While I have shown my invention as applied to socket wrenches, it will be evident that it is equally useful for any tool requiringa: cross, or T, shaped handle, or in fact, to any tool requiring a handle which may be bent after insertion in a working member. And although I have shown and described only one embodiment of my invention it will be readily understood that many changes and modifications may be made therein within the scope of the followingclaims without departing from the spirit and scope of the invention,.itbei1'1g my intention to claimthe same broadly in Whatever form its principles may be em ployed. M

lVhat I claim is: p

1. The method of naking. a tool comprising forming; atool head having an opening; therethrougrh, positioning a handle in said opening with its end portions extending'beyond the surface of the head, and bending said end portions in such nanner as to distort the intermediate portion within the opening whereby to restrain m orement of the tool head thereon".

2-. The method of making, a tool' comprise ingforming" a tool head having an opening 5 therethroug'h, positioning. a handle in said.

opening with its end: portions extending'be yond the surface of the head, and bending said end portions in the same plane whereby todistort he portion of the handle within the opening and restrain movement ot the tool head thereon.

3.- The method of making a tool comprising forming a tool head having an opening therethrou gh', positioning a handle in said openin-g'with its end" portions extending be yond' the surface ofthe head, and bending said end portions inthe same direction whereby todistort the portion of the handle within the opening and restrain movement the toolhead thereon.

4. The method of forming. a tool of the class described. which comprises providing a wrench socket having a hole extending therethrough at right a 'igles to the a dsof the socket, inserting a handl'e through said hole bending the handle upwardly adjacent the surface of the socket to distort the portion in the hole and to form, portions for one hand operation of the wrench then bending each upwardly extending end of the wrench outwardly to be in substantially the same axis and parallel to the axis of the hole in the socket to form two handles for the applicatioon of increased torque to the socket.
