the key 13 therein,

dle from rotating onlthe sleeve member 11,!

A wooden handle 14 is slidably mounted on the sleeve member 11 and is provided on its inner end with a longitudinally ex' tending slot 15, which is adapted to receive thus preventing the hanwhile permitting the handle to be rotated of the cap, the purpose of which will be hereinafter more fully described,

' ber 11.

V The cap 16 is screw threadedly fitted in the end of the sleeve supporting member 11 and has its-opening 18 in alinement with the opening 3 in the wall 2 of the-socket memberv 1,/thus permitting the ejecting rod to be arranged in the sleeve member'll and socket 1 to be hereinafter more fully de scribed, V H The cap 16 is provided adjacent its periphery at diametrically opposite points with openings 21 which are adapted to receive therein the ends ofa spanner wrench for se= curing the cap against the end of the handle 14 also within the sleeve supporting mem- 'The ejecting rod is designated 23 and is arranged longitudinally in the handle supporting sleeve 11, and has its inner end extending through and beyond the wall 2 of the socket '1 and terminates at a spaced distance from one end wall of the slot 6, as clearly shown in Fig. 2 of the drawings. A supporting stop cufl' 24: is secured to the rod adjacent its inner end and is located in the bore of the sleeve 11. A relatively weak coil'spring 25 surrounds said rod and has one end secured to the stop cufl'24l and its voposite end abutting the inner end of the stud 19 of the cap 16, whichwill be hereinafter more fully described.

The socket member 1 is adapted to receive the tapered head 26 of the tool shank 27 therein, whichshank is illustrated in the drawings as a screwdriver; The tapered head 26 has its extreme end beveled onop posite sides, as at 2 8, andis adapted to frictionally engage the side wall 7 formed by the slot 6, when the head is inserted in the socketmember 1. The head 26' is ta pered, as shown, and is frictionally fitted in the socket member 1 and has itsangular faces 28 alined with the reduced portion of the socket 1 formed by the Walls 7, and is by rotating the sleeve and socket therewith,"

inserted therein and its extreme inner end abuts the inner end 29 of the rod 23, thus inserted in the socket 1 when desired.

'The'handle member 1 1 is provided with a plurality of longitudinally extending grooves 31', which are arranged at 'a spaced distance apart around the exterior thereof, so that a firm grip may be applied to the handle when desired. p r

In assembling the device the handle is arranged, upon the supporting sleeve 11.

The ejecting rod is fpositionedjwithin the handle and socket, and the capj 16 is screw threadedly fitted in the sleeve 11 and re movably secured to the outer end of. the

handle, The tool, whether it be -a drill,

screwdriver or the like, has a tape'r'edlhead 26, which is of the standard type, in serted into the tapered bOIB Qf thB socket member 7 o l, and has its inner end abutting the inner end of the rod 23, thus forcing the same outwardly and beyond the flange of the cap 16 whenthe device is ready forfuse. When it is desired to remove the tool from the socket 1 end of the rod 23 either byv striking the same with a hammer or hitting the same upon some support, driving its inner end into en; gagement with the inner end of the head pressure is applied to the outer l 26 ofthe tool, thus ejecting the same from the'socket 1; V What is claimed is: Y i In a tool handle, a cylindrical metallic member having a front portion provided with a tapered bit receiving socket rear portion provided with a socket opening out through its rear end, said member hav ing a relatively narrow passage located beanda" tween and establishing communication between said sockets, a portlon of the 1111181" wall of the socket in the rear portion being screw threaded, an annular flange formed on the outer side of and extending outwardly from the member adjacent the front end of said rear portion to provide a shoulder, a key formed on the outer side of the rear portion and extending rearwardly from and formed integrally with said shoulder, a grip applied to said rear portion and provided with a groove to receive said key, a hollow nut adapted to'be threaded into said rear socket and having a relatively large flange adapted to engage the rear end of said'grip, the threading of the nutinto said socket forcing the grip upon said rear portion over the key and against said shoulder, a pin slidably mounted in the socket of said rear portion and having its ends located in said passage and nut, a shoulder carried by said pin adjacent said front end, and a spring surrounding said pin between said shoulder and nut.

In testimony whereof I afiiX my signature in presence of two Witnesses.
