Letters Patent No. 76,020, dated .March 24, 1868.
IMPROVEMENT In AWL-HANDLES.

TO ALL 'WI-IOM. IT MAY CONCERN:
Be it known that I', D. R. -NIGHT, ot' Sturbridge, in the county of Worcester, and State of Massachusetts, have invented a new and useful Improvement in Handles for Awls, Ste.; and I` do hereby declare that the following is a full, clcar,'and exact description thereof, which will enable those skilled inthe art to make and use Athe same, reference being'had to the accompanying drawings, forming part of this specification, in which- Figure 1 is a side view of my improved awl-handle, partly in section. Figure 2 is a cross-section, taken in the line a; x, fig. 3. Figure 3 is an end view, showing the application of the fastening and unfastening wrench;
Similar letters of reference indicate corresponding parts.
This invention relates to a new and useful improvement in-tlie construction of handles forawls, and other similar tools secured by a tang; andit consistskin a screw fastened inthe end of the handle, and a conical nut enclosing asplit cone, whichgripes the tang when pressed downinto the smaller end ofthe conical nut, by means ofthe sere v in the handle, operated on by a hook-wrench, as hereinafter more particularly described.
A represents 'thehandle of an awl constructed in the ordinary manner, in Athe lower end of which is fixed asolid blunt screw, at7 which has a' conical nut, b, fitted on it, to lie-close at the upper side against the handle when screwed on tight. In the 'smaller end of. the conical nut I isa split-cone, c, which `is bored in the centre, to receive the tang of the awl for any similar tool, as shown in the drawing.
The split cone or conical wedge-e is dropped` into the nut Z1, and the 'tang is insert-ed in it, when, to fasten it firmly, the nut is screwed on the screw a, und drawn tight by a hook-wrench, e, tig. 3. VThe end of the screw a bears on the larger end of the split cone or conical wedgee, and forces it down into .the bottom ofthe conical nut I), and'thus gripes securely arid-.holds fastlthe tang of the awl or other tool.`
Hoving described my invention, I claim as new, and desire to secure by LettersPatcnt` The conical nut I), in combination with the ilat-ended screw a and split cone c, when constructed. and
-arrangedso that the split cone shall be mndc to closeupon theawl' by the action of the` \conical nut alonewhen screwed up, as herein shown and described. i
