SPECIFICATION forming part of .Letters Patent No. 531,031, dated December 18, 1894.

I Application led` October 1l, 18974. Serial No.` 525,555. (No model.)

.To @ZZ whom/it may concern;

Be it known that I, THOMASF. HARRIS, a citizen of the United States, residing at Anniston, in the county of Calhoun and State vof Alabama, have invented certain new and useful Improvements in a Combined Lead- Pencil and Sharpener; and I do hereby declare the followingy to be a full, clear, and exact description of the invention," such as Ywill enable othersV skilled inthe art to which it appertains to make and use the same.

My invention relates to improvements in combined lead pencils and Sharpeners therefor, and the same consists of a pencilA made with the lead loose therein, provided with means for gripping the lead when in use, and having normally seated at its rear end an improved detachable Sharpener for the lead.

It also consists of certain details of construction and combination of parts, as will be more fully hereinafter set forth and pointed out in the claims.

The invention is clearly illustrated in the accompanying drawings, which form a part of this specification, in which- Figure l represents a side view of a pencil with all'the parts in place. Fig. 2 is a vertical longitudinal section of the same. longitudinal section ofthe same taken at right angles to Fig. 2, and showing the sharpening device detached from the rear of the pencil and applied to the front thereof in the position it assumes when it is sharpening the lead. Fig. 4 is a detail view of the front' sleeve or collar, with the clamp removed. Fig. 5 is a detail of the spring clamp, and Fig. 6 is a detail of the sharpening device.v

Referring to the drawings now by letter, A represents the body of the pencil, which is longitudinally bored for the reception of the lead B, which fits loosely therein. Around the front portion of the body A ts a sleeve C, which has a bifurcated extension c which is tapered down at its end to closely encircle the lead B. This sleeve'O is slotted as shown at c.

D represents a lead` gripping or clamping piece which fits over the end of the extension c of the sleeve C, and has projecting lingers d d with inturned flanges or ends d d. These flanges have notched ends which fit into the slots c c', to grip the lead, and by reason of Fig. 3 is a' this construction, the sleeve C has a limited longitudinal movement in the slots 'c' c.. f

n At the rear of the body A is normally located the sharpening device. As shown, this consists 0f a sleeve or collar E preferably `made of steel, which ts the end of the body A and is held theretoby friction. The outer end of this is taperedoff and crimped as seen at`e and thereby formed on its inside with a cone -shaped cutting or grinding surface. Surrounding the collar E is a sleeve F adapted to .protect the pointed and roughenedend e and also to receive and hold a rubber G.

The parts of the device are all normally disposed substantially as` shown in Figs. l

and 2, and from the foregoing description, it

is thought the operation will be readily understood. In using the pencil the lead is drawn out by means of the clamp C and held in place during the writing operation by the slight natural pressure of the fingers on the fingers cl d. When the writing is finished the lead is permitted "to drop back into the body A. When the point of the lead becomes dull and rounded, and it is desired to sharpen it, the Sharpener E is detached from the rear endvof the body'A and placed over the tapered portion c of the sleeveC, the lead having been previously drawn out and held by means of the clamping lingers d d moving inthe that I do not limit myself to the exact con-y struction herein shown and described. Minor changes may be made therein without departing from the nature or spirit of the invention.

Having now described my invention, what I claim as new, and desire to secure by Letters Patent, is-v f 1. A lead pencil consisting of abody part in which the lead is loosely inserted, a metallic sleeve surrounding the body portion having a bifurcated tapering extension with thereof crimped to form on its inner side a; opposite slots therein, and a lead gripping or cone-shaped cutting or grinding surface, and clamping device, consisting of a collar sura protecting sleeve surrounding said collar 15 rounding said tapering extension, having and adapted to hold a rubber, substantially 5 fingers extending backwardly therefrom with as described.
