Specication forminghpart of Letters Patent N o. 173,076, dated February 1, 1876; application iile y December 3, 1875. 4

A To all whom it 'may cocein:

.Be it known that L'DANIEL M. SoMERs, ofthe city, county, and State of New York, have invented an Improvement in Pocket, Pencils, of which the following is a specifica- The invention relates to that class of poch-j letpencilsin which a'n ordinary lead-pencil is Vcontained in a case or holder, andmore espe,

cially to such cases or holders wheiiprovided with a sliding carrier, having a means for holding the pencil at any p oint of its adjustment inthe case, and propelling it into the case for protection, or protruding it therefrom for use,

in writing, as devised by and described in the application of Mark Saii'ord.

n .,lhe improvement.consists in the means for engaging the sliding carrier with the` pencilstock, as will be more specically hereinafter` l pointed out, v

In the accompanying drawings, which illustrate my invention and constitute a part of this specication, is represented, in-

Figure l, a plan; Fig. 2, a longitudinal section; Fig. 3, a plan of a' modification; Fig. 4, itsv longitudinal section; Fig. 5, a transverse section of Fig. l on line w,- Fig. 6, a transverse section of a holder, showing a modified form of the projection 6; and Fig. 7, a transverse section of a round pencil with one side made hat.

A tube, l, made of metal or of rubber or similar material, by any ofthe modes of forming 'such articles, constitutes the case or holder. It may bea plain tube, have an ornameuted exterior surface, be provided with knurledor beadedends, be made With a closed butt-end, or be furnished with a rubber eraser held within one of its ends by any of the known means pencil Vwhose diameter is but slightly less than' that of the interior of the tube; but a pencil vof polygonal form, as in Figs. l, 2, or one lhaving. a single fiat side, asin Fig. 7, may readily be introduced into the tube when the Hat side of the pencil is opposed to the flan-ge or tooth of the carrier, las Ais best shown inFig. 7.

1f the sliding carrier is moved to the front end of the slot 2, and a pencilghas b'een introduced intothe tube, as just described, to a distance which leaves its point 7 protruding sufficiently to be used in marking. the carrier may lbe secured to the said pencil by simply turning the pencil a distancesufticicnt to cause its r-ib or raised corner, formed by the union ofthe planes`of its -iiatsides,.to engage the flangey or tooth 5, which,-by reason of its thin edge, cuts into or displaces the wood, so as t0 forma seat, which aftixes thej pencil thereto. If a round pencil with one dat side has 'been used the flange or tooth will cut into the Wooden stock at the point where it meets the increased diameter of the'pencil, as W'ill he readily understood from an inspection of Fig. 7. Thus 'united vto the sliding carrier, the pencil maybe moved thereby into and out of the tube at the willof the user.

When in a closed position, the pencil-point will be fully protected by the walls of the tube which inclose it, and when its point is projected for use aconvenient means for manipulating it is furnished by the case or handle.

When the pointis worn away the pencil may be disengaged from 'the holder, readjusted in anew position, and, operated as v before eX- plained. v

By this device the pencil may be adjusted, held, projected, and used until a short and valueles's piece remains, thus affording a means for the economic consumption of a pencil, which at the same time affords a suitable handle for it, without regard to the lengthv of the pencil y itholds.

In rapidly-adjsting polygonal pencils in this holding devlce, or Where too much. force is used in rotating the pencil into engagement with the pencil-rib, the tooth of the carrier may be forced entirely through said rib, and

s cLEvELAND,

that when one fang has cut through the rib,- the other will abut against it, and form a stop tending to limit further rotation of the pencil.

It is apparent that the device, as thus far explained, is not adapted to hold a round pencil, having an unbroken periphery, for the rea son that such a pencil cannot be introd uccd by a right-line movement into the case or holder, since it cannot pass by the tooth or ange 5; but in Figs. 3 and 4 the said tooth or ange is given the pitch of a screw-thread, whereby it is adapted to engage with the surfacefof a round pencil, or with the ribs of a polygonal pencil, and propel it into the tube when the pencil is rotated.

VVVhen'apencil has iu this manner been secured to the carrier, and ladjusted to the proper position, it may be moved in and out of the case, as has been described with reference to Figs. land 2. When its point is worn away it may be readjusted by simply screwing'the pencil outward.

The effect of the engagement of the pencil with the projectin g tooth of either form ofthe holding device is that the carrier is forcibly drawn against the surface of the case, and creates such a frictional bearing thereon as will enable the carrier to supporta pencil at any point where it may be left in its longitu dinal or sliding movement upon the case.

I claim- 1. A pencil-holder, consisting of a slotted tubular case, adapted to receive a pencil within it, combined with a sliding carrier, by which the pencil may be propelled in and out ot' its case, the said carrier being provided with a projection having a screw-thread pitch to engage with and adjust the pencil, substantially as shown and deserihed.-

2. A pencil-holder, consisting of a slotted tubular case, provided with a sliding pencilcarrier, said carrier being constructed with a bearing-tooth,`for engaging with the pencil, and adapted by its frictional bearings upon the exterior ofthe case to retain the pencil at any point of its longitudinal adjustment, substantially as shown and described.

3. In combination, with a' longitudinallyslotted case, a sliding pencil-carrier, provided. with a holding-tooth, so constructed as to permit a dat-sided pencil to pass freely under-v neath it, and engage its projecting corner or surface thereon when the pencil is slightly rotated, substantiallyas shown andl described.

4. A sliding pencil-carrier, provided with a projecting tooth, having fangs which bear on opposite sides of a corner or rib of a polygonal pencil, whereby said pencil may be readily inserted to a proper point in its case, adjustably secured to said carrier, and propelled longitudinally therein, substantially as shown and described.

In testimony whereof I have signedmy
