LEAD-PENCIL.

SPECIFICATION formingpart of Letters Patent No. 236,215, dated January 4, 1881. Application filed March 13,1880. (No model.)

To all whomlt may concern:

Be it known that l, THoMAs B. DE FOREST, )f Birmingham, in the county of New Haven and State of Connecticut, have invented a `new Improvement in Lead-Pencils; and I do hereby declare the following, when taken in connection with the accompanying drawings, and the letters of reference marked thereon, to be a full, clear, and exact description of the same, which said drawings constitute part'of t.is specification, and represent, in-

Figure 1, side view; Fig. 2, a vertical sectional view.

This invention relates to an improvement in lead-pencils such as are made from a cylinder of wood with a stick of lead through the center.

In many cases it is desirable to attach the pencil to a cord, as, for instance, to slates, books, and many other places; but the pencils as usually produced afford no convenience for such attachment.

The object of this invention is toprovide the pencil with such means for attachment, which shall he a permanent part of the pencil; and it consists in the pencil provided with a perforated cap, through the perforation of which the cord may he secured, and as more fully hereinafter described. i

A represents a common wood lead-pencil. B is a metallic cap, formed from sheet metal or other suitable material, struck up so as to closely flt one end of the pencil, and perforated at its` closed end, as at a, and also with a side per larger than the perforation a. This completes the pencil.

To attach the cord, pass one end through lthe perforation a, thence turning outward through the perforation b; then tie a knot or make other enlargement in the end of the cord, and draw such enlargement through the perforation b, against theperforation a, as seen in Fig. 2, which secures the pencil to the cord in a neat and convenient manner. Instead of the side and end perforations, the perforation may extend diametrically through the cap, and the cord be passed through and tied to itself, forming a loop in the cord through the cap.

By this construction I produce, as an article of manufacture and sale, a wood lead-pencil permanently provided with means for attaching to a cord.

I do not broadly claim providing a leadpencil with means fo'r suspension.

I claim- As an article of manufacture, a wood leadpencil provided with a perforated metal cap constructed with perforations a b, substantially as and for the purpose described.
