TOOL HANDLE.

Application led February 13, 1924. i Serial No. 692,491.

To alt whom t may concern.'

Be it known that I, DAMAS C. F ILIA- 'rnnAUl/r, a citizen of the United States, and a resident of Chicago, Cook County, and State of Illinois, have invented ce'rtainnew and useful Improvements in '.lool Handles,` 'of which the following is declared to be a full, clear, and exact description.v

This invention relates to tool handles and its principal object is to provide improved means for securing a tool lhead such as a hammer head or the like to the handle. Another object is to provide a wooden handle with a metal reinforcement therein extending from end to end and having associated means of improved form I'or rigidly seeming the tool head to the. handle. Another object. is to provide simple means for locking the parts in assembled eomlition. Another object is to provide in a. halnmer of this type, a cushioned grip whereby the hammer may be held more firmly and whereby much of the jar may be taken oill the hands of the workmen using the hammer. With these and other objects and advantages in view this invention consists in the several novel features hereinafter fully set forth and claimed.

The invention is clearly illustrated in the accompanying drawing, in Whichz Fig. l isa view partly in side elevation and partly in centrallongitudinal section of a tool handle embodying a simple form of ther present invention with a tool head secured thereto; Fig. 2 is an end view looking in the direction of the arrow 2 in Fig. 1 partly broken away; Fig. 3 is an end view of a certain wedge used for connecting the handle to the head;'Fig. 4 is a perspective view of the wedge; Fig. 5 is a perspective view of the fragment of the Wooden shaft or handle portion; and Fig. 6 is a detail cross-section taken on the line 6-6 of Fig. 1.

Referring to said drawing which illustrates a'simple embodiment of the present invention, the reference character 7 designates a wooden shaft or handle having a tapered end 8 adapted for connection with the tool head 9 which in this instance is illustrated as comprising a hammer head of ordinary and Well known form. As usual the hammerhead has a socket 10 in which vthe handle is iseeured, said socket being formed with reverscly

tapered end portions

11, 12 as is customary.

rlhe handle 7 is centrally bored lengthwise of itselt" to form a hole 13 and in said hole is placed a reintoreement rod 14 which tits tightly in the hole and extends from end to end of the handle. One end of the rod 14 is formed with a head l5 and its other end is formed with screw threads lt. Secured on and surrounding one end ofthe handle 7is a metal cap 17 against which the head 15 of the rod l-it bears. Said cap is formed with an end wall 18 which bears against the end of the handle and with a band-like member 1t) which surrounds the end portion of the handle. This eap provides a substantial abutment. member for thc head of the rod I4, to bear against and also protects the end ofthe wooden handle.

The. end 8 of the lhandle which engages with the tool head, is formed with

saw kerfs

20, 21 arranged at right angles to each other and the bore of the handle is increased in diameter at this end to form a recess or cavity 22.

A wedge member 23 is employed in connection with the reinforcement rod to rigidl secure the tool head 9 to the handle. baid wedge comprises an internally threaded tubular portion 24 and tapered or Wedgelike wings or ribs 25, 26 that extend at right Y angles to each. other. The Wedge member 23 is contained in the cavity 22 and saw

kerfs

20, 21 and the threaded rod engages in the threaded hole of the wedge mem er.- In the outer end of the wedge member 2,8, may be formed one or more notches 27, two being shown, and the threaded vend of the rod 14 may be notched as at 28 to leave furcations 29 that may be bent into the notches 27 of the wedge member 23 after the rod has been screwed tightly into the Wedge, to thereby prevent the rod from being turned back. When the wedge member is drawn into the cavity 22 of the handle, the

wings

25, 26 spread the slotted end portionstn of the handle and force them into frictional engagement With the tapered face 11 of the socket. The slotted end of the handle is spread in several directions by the angularly disposed Wings, and a firmer grip is thereby had upon'the tapered wall of the socket of the tool head. In case the parts become loose after continuedl and hard usage the bifurcated end of the rod may be straightened and the rod screwed up to tighten the 'parts after which the urcations 29 may be bent down again to lock the fparts together.

To rovide a cushioned grip for the handle, t e latter is turned down as shown, leavin a shoulder 30, and between said shoul er 30, and a shoulder 3l of the cap 17 is secured a sleeve 32 made of rubber or rubber composition. The outer face of the sleeve may be roughened to provide a firmer slack from any cause.

grilphfor the hand.

e device is simple` in construction, 1s easily assembled and provides a reinforced tool handle which is not likely to break when subjected to the ordinary rough uses to which hammers are put. v.By providing a slotted head for the reinforcement rod, an ordinary screw driver may be used for tightening up the parts in case they become The tool handle can be used in connection with hammer heads, axe heads, and various other tool heads as is well understood. i

More or less variation of the exact details of construction is possible Without departing from the spirit of this invention; I desire,.'therefore, not to limit myself' to the exact form of the construction shown and described, but intend, in the following claim,

ananas herem.

I claim as new,l and desire to secure by Letters Patent:

A tool handle com rising a wooden handle having an kend or engagement in the socket of a tool head, said end having a cavity therein and equi-distant angnlarly disposed slots radiating from said cavity, a metal cap on one end of the handle, a reinforcement rod extending lengthwise through said handle and having a head bearing against the end of said cap and threaded at its other yend, and a Wedge member having an internally threaded tubular body portion and equi-distant angularly disposed wedge-like wings radiating therefrom, said wedge member having a noncircular countersnk in its outer end and being confined in said cavity and slots of the handle, and said reinforcement rod being threadedly secured in said wedge member and coacting with said wedge member to spread the slotted end ofv the handle into frictional engagement with the socket of the tool head, the threaded end of said red being bifurcated and the furcations being bent into said non-circular countersink.
