TO ALL WHOM I'I MAY ONCERN:

Be it known that I, NATHAN S. CLEMENT, of New Britain, in the county of Hartford, in the State of Connecticut, have invented certain newand useful improvements in Handles for Awls and analogous tools; and I do hereby declare that the following is a full and exact description thereof. Y

My device -seizes and liberates the awl by opening and closing a divided socket, This general mode of construction has been long known, but my invention is different from any before known to me, and superior thereto.

I will iirst describe what I consider'the best means of carrying out my invention, and will afterwards designate the points which Ibelieve to be new. -The accompanying drawingsform a part'of, this specification.

Figure I is a central longitudinal section.

Figure 2 is a View of the rear-end.

Figure 3 is a section showing on a larger sca Similailetters of 'reference indicate like parts in all the iigures.

A isthe main body of the handle. It is perforated through its axis to receive the steel or iron stein B, and is recessed toward the rear, as indicated by A, to form a receptacle for the tools which are not in use. is a cover for this receptacle. It also containsa metallic nut, c, which fits on the threaded end' of the' stein Il, as indicated. This nut c is star-shaped on its outer surface, as shown in iig. 2, and is' larger, both at its inner end and outer end, than along the centre of its length. It is formed of type metal, or analogous material, and is cast in place. p The process of forming it consists in putting the cover C in a proper positionl in sand or in a mould, andv after inserting the stem B, or, by preference, a highlypolished steel former made of corresponding shape, the type metal is poured in until the mould'or the cavity is full. After the metal is chilled the stem B or corresponding former is removed by unscrewing it, and the surfaces of the metal c are subsequently finished by'hanfl or by machinery. The opposite end of the stem B is split for a considerable distance, as indicated by The stem is also formed with a tapering head, as indicated by B. 'lhe splitb receives a nail or wire which is driven through the handle andthrough the split after the stem is put in its proper position in the handle. The tapering head B fits to the corresponding interior of the ferrule D. This fcrrule is secured on the handle A by embracing it for a little distance, the surface of the handle being formed irregularly, so as to lock with lthe corresponding shaped ferrule, as indicated in the drawing. The ferrule D is cast in place by means similar to that just described for the production of the nut c. -A small amount of longitudinal motion of the stein B is allowed, by driving the nail or wire a little above the lower end of the split ,It will, of course, be understood that a suitable socket i-s formed for the awl or other tool, and that this socket coincides in position with the split Z1, but is not as deep. The socket is square in section.

The parts of my handle being properly put together, the' cover C is turned in such direction as to partially unscrew the nut c from the screw on the stem Il. It is then'pushed forward so as to carry the stem with it, and this, by pushing out or protruding the tapering front end of the stem B beyond the ferrulc D, allows it to spring open a little. The awl E is now inserted in its proper position, and the cover C is screwed in the opposite direction, so as to draw the stem B into the nut c. This movement draws the tapering part B down into the tapering socket in the ferrule D, and causes it to be pressed together with such force as to confine the awl E. In this condition the tool may be used for any length of time, and the reverse of thel above-described operation will liberate the awl and allow the handle to be lcarried in the pocket, or allow the tools :o be changed at pleasure.

I do not claim separately the divided and tapering stem 'B B', operating as represented, nor thc nut e, nor the handle and cover A C. I do not claim anything shown in the patent issued to D. II. Chamberlain, dated le the mode of joining the fcrrule and handle.

. May 30, 1848, but having now fully described my invention, what I claim as new therein, and desire to secure by Letters Patent, is as follows:

I claim'as a new article of manufacture the awl handle 'herein described, having a tapering head, B, on a movable stem, operated` by a nut, c, locked in 'the cover C, by being headed or enlarged to match the recesses provided in said cover, as herein set forth.

N. S. CLEMENT.
