LEAD-PENCIL.

SPECIFICATION forming part of Letters Patent No. 770,777, dated September 27, 1904.

Application filed September 25,1903. Serial No. 174,655. (No model.)

To all whom it may concern.-

Be it known that I, CHARLES W. PADAN, a citizen of the United States, residing at Chillicothe, in the county of Ross and State of Ohio, have invented new and useful Improvements in Lead-Pencils, of which the following is a specification.

My invention relates to improvements in lead-pencils.

It has for its object to provide for the use of the pencil without resorting to the sharpening operation, as necessary in the use of the ordinary lead-pencil, to effect that end in a simple, effective, and economical manner and to otherwise promote utility, convenience, and facility.

Said invention consists of a sheath or closure for a lead adapted to provide for access laterally to the latter and means for actuating or projecting said lead comprising, preferably, a sleeve or carrier applied to said sheath, with an inbent or inturned extension or portion arranged to enter said sheath laterally and clasp or clamp said lead, thus providing not only for the projecting or moving forward or outward of said lead, but also for obviating axial or oscillatory movement of the lead which it would otherwise tend to have, especially if the bore 0r passage containing or receiving said lead should not closely encompass the latter and which would be exceedingly unsatisfactory, as the wabbling action of the point of the lead would, as found in practice, have the effect to slope or bevel off said point in its contact with the paper or surface in the operation of writing. Said sleeve has also means for its retention against inward or rearward movement, although, as stated, permitted to have forward movement for the purpose stated, the object of such retention being apparent later.

In the accompanying drawings, illustrating the preferred embodiment of my invention, Figure 1 is a side elevation thereof. Fig. 2 is a longitudinal section. Fig. 3 is a crosssection of the same, and Fig. 4% is a'detached perspective view and a cross-sectional view of the pencil-lead clasp or clamp.

In the carrying out of my invention I provide a sheath or closure 1, produced, preferably, with a tapered forward or outward end, and which tapered portion is fitted with a correspondingly-shaped metallic sleeve or cap 2, said sheath or closure having a central longitudinal passage or bore 3 receiving the lead 4 and having a longitudinal lateral slot 5 intercepting or communicating with said passage or bore. A sleeve or'carrier 6, fitted to slide or be moved longitudinally upon the sheath or closure 1, has formed therewith in the direction of its length an inward-extending loop 6*, entering the lateral slot 5 of said sheath and sprung around and therefore clasping the lead at at its inner or inclosed end within the bore or passage 3 to provide for the forward or outward movement or feeding of said lead, as it may wear away or be reduced by use. Thus said sleeve or carrier, by suitably actuating it, not only effects the movement or feeding of the lead, but also provides for the retention thereof against axial or oscillatory movement in the use of the pencil, which would otherwise occur, especially if the transverse area of the lead-receiving bore or passage permitted lateral movement of the lead, and which, as before stated, would tend to the beveling or sloping off of the lead at its point, as has been found in actual experience with pencils whose lead is similarly arranged in a sheath or closure. Said sleeve or carrier is equipped or armed at its rear edge with teeth or projections 6 to engage and prevent the rearward or inward movement thereof, in

order to prevent when the lead has become exhausted the same sheath being replenished by a new lead. Said sheath may have suitably carried upon its inner or upper end a rubber tip or eraser, as shown or otherwise, the convenience of which is apparent.

It will be understood that I do not limit myself to details herein, as they may be changed as circumstances suggest without departing from the spirit of my invention and said invention yet be protected.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, is

A lead-pencil consisting of a body portion having a longitudinal passage or bore, and a correspondingly-extending slot opening into said passage or bore, a pencil-lead movable Within said bore, and a sleeve or carrier having its outer member encompassing said body portion and a concentric member clasping said lead and united to said outer member by parallel plate-like portions fitting close one against the other and arranged Within said slot, said sleeve also having at its rear edge teeth adapted to engage said body portion and
