IMPROVEMENT IN PENCIL-HOLDERS.

Specification forming part of Letters vPatent No. 114,893, dated May 16 1871.

To all 'whom it may concern:

Beit known that I HORACE J. WICKHAM, of

.Manchester, county of' Hart-ford and State of Connecticut, have yinvented certain new and useful Improvements the Manufacture of Pencils; and to enable others skilled in the art to make the same, I will proceed to describe, referring to the drawings, in which the same letters indicate like parts each ofthe figures. A

The object of this invention is to produce a cheap, efficient, and durable article.

In the accompanying drawings, Figure l is a l 'sectional side view. Fig. 2 is a side view of the same, having a cap and watch-key attached thereto.

a. is a pencil-stock, of anysuitable material, having a chamber c, formed therein for the reption of the lead d. The end e of this stock is cone-shaped, and is provided with a screw-tl.\read, f, just back of and in close proximity with the cone-shaped end. This outer end or cone shape has a longitudinal slit, so that di'erent size leads may be introducedy into and compressed therein. h is a screw-threaded cap, made from fiat sheetmetal blankA very much in the same way or man- .ner of forming cartridge-shells, and afterward finish the cap by spinning up the screw-thread j" thereon inthe common way, so as to produce a complete and perfect finish of the screw-thread f and conical end h. Thus I am enabled to insert into the chamber c leads of -Variable sizesA and lengths, equal to the length of the stock, and, by turning said cap h onto the screw-threadf over the conical-sl1aped end e of the pencil-stock a, it will, at its extreme point, rmly compress the -longitndinally-slitted cone-shaped end e of the stock, at' or near its extreme point, against the body of the lead, and, when the lead is worn up, by simply loosening the cap h the lead can be easily and quickly readjusted and firmly secured in the gripe of the slitted end by turning the cap firmly onto the screw of the stock. i is a cap for lthe opposite end of the stock. This vcap may be made a perfect duplicate of the cap What I claim, and desire to secure by Letters.

l. As an improved article of manufacture, a'

pencil, the stock of which has a chamber for an adjustable lead, an exterior screw-thread, a conical-shaped end, and with a longitudinal slit therein, all formed in one piece composing the stock, combined with a screw-threaded cap having a conical end formed from sheet-metal, and

serving to clamp the stock to the lead, constructed, as described, so as to t to the conical end ofthe stock and give support to its extreme point, all substantially as set forth. A

2. In combin( tion with a finishing cap or socket of the pencil, the watch-key k aiiixed thereto on the line of lits axis, substantially as and for the purpose set forth.
