PENCIL.

SPECIFICATION forming part of Letters Patent No. 378,084, dated February 21, 1888.

I Application filed May 4, 1887. Serial No. 237,108. (No model.) I

To all whom, it may concern:

Be it known that I, J AMES F. DoDD, a citizen of the United States, residing at Delaware, in the county of Delaware and State of Ohio, have invented certain new and useful Improvements in Pencils; and I do hereby declare the following tobe a full, clear, and ex act description of the invention, such as will enable others skilled in the art to which it appertains to make anduse the same.

Figure 1 is a side elevation of the device. Fig. 2 is a longitudinal central section of the same. Fig. 3 is a longitudinal sectionof the two parts which make the body of this device. Fig. 4 is an elevation showing a modified form of construction. Fig. 5 is a perspective view, enlarged, of the head. Fig. 6 is a cross-section of the driver. Fig. 7 is a longitudinal section of the same. Fig. 8 is a perspective view of the driver, showing the modified construction. Fig. 9 .is adetail in side elevation, showing also a modified form of the driver; Fig. 10, a detail in perspective, showing how the head is adjusted to the body of the pencil; Fig. 11, cross-sectional views showing various forms of constructing the body.

This invention relates to improvements in the construction of that class of pencils in which the lead is moved by means of adriver that is, a device that will operate to force the lead forward, and the points of novelty in the present instance-relate to the construction of the several parts which make up the device and their'combination with each other, all as will now be more fully set out and explained, reference being had to the accompanying drawings.

In the drawings, A represents the body of the pencil, which is made in two parts, a a, of wood, hard rubber, or any suitable or convenient material. One or both of these parts are slightly cut away from the top end to the place a, not far from the tip or place where in usethe pencil projects, thus forming here a rabbet or shoulder. Each of these parts may be grooved longitudinally on the inside at o. for the reception of the lead; or, if desired, the groove in one part may be made deep enough to hold the lead and the otherp'art may be simply a cap to be applied over the grooved part, as shown in Fig. 11.

Near the tip the parts are secured together by a metal or other band, B; or, if preferred,

an entire covering, '13, may be provided for.

the tip, as shown in Fig. 4, and in that case the tip may be fastened'by means of a brad. The

heads of the parts a a are secured together. by

means of the metal cap 0, which has on its lower edge internal projecting flanges, c, adapted to fit between the two parts a a. The use of these flanges is-pr-incipally twofold: first, to keep the two parts a a of the body a sufficient distance from each other, so that, together with the shoulder at a, a narrow slot, a", shall be provided from the head nearly to the tip to allow free passage for the piece d of the driver D, which fits into this slot. these flanges c, which are made slightly springy, is to hold the cap 0 securely in its position upon the head of the pencil. By this construction the cap can be very readily applied in place, and will be held sufficiently secure there The other use of to prevent its removal in any ordinary condiis necessary to put the lead into the body, the cap can be easily removed. I

The driver, by which is meant that part of the pencil which forces the lead'forward, may be constructed in various ways. The body of it is a band or ring adapted to fit snugly upon the body A, but so as to be easily moved to and fro. The driver shown in Fig. 1 has fixed centrally within it a tube, (1, which is adapted to fit into the groove 0!. of the body of the pencil. In one end of this tube one end of the lead is fitted,and will easily be held sufficiently secure therein to secure the backward as well as the forward movement of the lead. .There is no difficulty as to its accomplishing the forward movement; but in order to make sure In the form of construction shown in Fig. 1

the driver can be merely pushed along the body of the pencil; but in the form of ,construction shown in Fig. 9, where the driver is made independently of the tube which holdsthe lead/the propelling movement is gained by having the body of the driver-screwthreaded, as at (1. Thus the driver can be moved up and down along the pencil-case by merely rotating it with the fingers, its helical thread operating upon the soft wood almost as well as if the wood were grooved. In this construction the tube is held by the crosspiece d", having upwardly-projecting flanges d. Thus in the backward-and-forward movement of the driver its edges will impinge upon these projections and force the pencil backwardand forward in the same manner as is accomplished when the driver is constructed as in Fig. 7; or this upward projection may come through the body of the driver, which is slotted at d for the purpose,as shown in Figs. 4 and 8. In orderto apply the pencil-holding portion of the driver to the body in this latter form of construction, the body is slit in the end, and the projections on the pencil-holding part can then be inserted in the slots. In this form of construction the springy character of the metal of which the body is made will keep it in its proper shape.

It will be readily understood that a piece of rubber,E,can be fitted into the cap 0. If desired, for this purpose,the cap 0 can be screwthreaded, so that the rubber can be easily put in and securely held in position. In the form of construction shown in Fig.1 it will be noticed that beyond the metal band B the ends a a are exposed. It may be desirable in some forms of construction to make the pencil in this way to sharpen its ends when necessary.

In the foregoing description, as well as in the illustration, only a very few of the many mechanical alterations in structure in making this device are indicated. It will be evident,

however, that the range of these changes is very wide; but they need not be further elaborated now, as it is hoped that the aim and scope of the present invention have been explained with suificient clearness to give a good understanding of. it.

Having now explained my invention, what I consider new, and desire to secure by Letters Patent, is-

1. A pencil made in two parts cut away and shouldered, and also grooved on their inner faces to contain the lead and seen red together at the tip and head, as set forth, whereby a slot is provided between the two parts, and combined with a driver provided with means for holding the lead, substantially as and for the purpose set forth.

2. In combination with a pencil made substantial] y as described, a cap, 0, provided with internal flanges, 0, substantially as and for the purpose set forth.

1 3. A driver, D, fora pencil, substantially as described, having within it aspring-tnbe, d, for receiving and grippingtbe end of thelead, substantially as and for the purpose set forth.

4. A pencil made in two parts and internally grooved for the lead, and also shouldered, the two parts held asunder to allow the pas sage for the driver by means of the shoulder at one end and a detachable cap at the other and secured together by means of said cap and a band near the tip, substantially as and for the purpose set forth.

5. In a pencil, a detachable cap provided with a spring whereby it can be held in posi tion, substantially as and for the purpose set forth.

6. A lead-pencil madein two parts and held together at one end by a detachable cap and at the other by a band or tip and provided with a driver having its body screw-threaded.

In testimony whereof I affix my signaturein presence of two witnesses.
