To all whom it may concern: I

Be it known that 1, WILLIAM ROLL, a citizen of the United States, residing at Sandusky, in the county of Erie and State of Ohio, have invented a new and useful Pen oil, of which the following is a specification. This invention relates more especially to an improved pencil comprising a casing which extends longitudinally ofthe pencil and is provided internally with a passage extending longitudinally and to the forward extremity of the casing for receiving an endwise adjustable lead or marking element adapted to project forwardly of said passa e.

ne object of this invention is not only to have said casing divided longitudinally of said passage into sections employed in holding the marking element in the desired adjustment but to render said sections capable of uniformly and efficiently gripping without liability of breaking the marking element.

With these objects in view, and to attain any other object hereinafter appearing, this invention consists in certain features of construction, and combinations and relative arrangement of parts, hereinafter described in this specification, pointed out' in the claims, and illustrated in the accompanying drawings.

In said drawings, Figure 1 is a side view of a pencil embodying my invention. Fig. 2 is an enlarged transverse section taken along the line 2-2, Fig. '1, looking forwardly. Fig. 3 is a transverse sectionish ow. ing the two sections oftthe illustrated easing unlocked from each other and one of said sections swung from over the other section to render the marking element free to be lifted out of the last-mentioned section. Fig. 4 is a longitudinal section taken along the line 4=a, Fig. 2, looking in the direction indicated by the arrow. Fig. 5 is a transverse section taken along the line 5-5, Fig. 4, looking rearwardly. F igs, 2, 3, 4 and 5 are drawn on the same scale, and portions are broken away in Fig. 4 to reduce the size of the drawing.

My improved pencil preferably comprises a casing extending longitudinally of the pencil and having a forwardly tapering forward end portion'6. Preferably said cas- .ing is substantially circular and uniform in cross-section from said tapering portion to the rear extremity of the casing. Said casattached to said ing (see Figs. 2-and 4) is provided internally with a passage 7 extending rearwardly from the forward extremity of the casing and-preferably into the rear portion of the casing.

Occupying the passage 7 is the endwise adjustable lead or marking element B of the pencil. Said marking element is shown as projecting forwardly of the passage 7 and as extending to a member 8 which is arranged internally of the rear end portion of the casing and carried by and rigid with one of two oppositely arranged sections A into whichthe casing is divided, as at 10, longitudinally of the passage 7. The member 8 forms a closure for the rear end of the passage 7 and also forms an abutmentor stop arranged to prevent displacement of the marking element rearwardly from the casing. Preferably each casing-section A extends from end to end of the casing and consists of a wooden strip, and the stop-forming member 8. preferably consists of a wooden piece which is glued or cemented, as at 9, Figs. 4 and 5, to the casing-section carrying said stop-forming member, but is loose relative to the other casing section. The passage 7 is formed partially'in each section A, and the member 8 forms a rigid rear end wall for said passage.

The casing-sections A are shown. connected together by a covering 12 which consists preferably of a single strip of suitable flexible fibrous material, such,for instance, as linen. Said strip is shown as extending from the tapering forward end portion 6 to the rear extremity of the casing and as covering the outer surfaces of the sections A between said extremity and said tapering portion, and said strip is pasted or adhesively surfaces in any approved manner. Said strip 12 is also shown as ex tending from one longitudinal edge of one section A transversely of the outer surface of said section in the direction of and to the thence transversely of the outer surface of the other casing-section. Said strip 12 has the portion thereof which is employed as a covering for the outer surface of a casing section, adhesively attached to said surface only. Said strip therefore participates in the formation of a hinge which hinges the sections A together and permits said sections, when unlocked from each other, to be swung apart.

casing to the rear extremity of the casing,

and I would here remark that preferably the space between the projectingportions'14 of the casing-section A carrying the stop-forming member 8 is supplied, between. said stopforming member and said casing-section, with cement firmly securing said stop-forming member to said casing-section. The inwardly projecting portions 14 of each section A are shown arranged intermediately of and spaced from the longitudinal edges of said section and spaced circumferentially of the marking element. It will be observed therefore that in the pencil illustrated (see Figs. 2 and 4) each section A has two inward enlargements in thickness, that said enlargements are spaced circumferentially and extend longitudinally of the marking element and form two of the inwardly projecting portions 14 of the casing, and that each inwardly projecting portion 14 of each section A is spaced from the adjacent inwardly projecting other casing-section. The casing, by having greater thickness at than between the inwardly projecting portions 14 of the sections A, is rendered strongest, as desired, along the lines at which pressure is exerted by said projecting portions against themarking ele-' ment. Preferably each inwardly projecting portion, 14 of each casing-section is arranged substantially diametrically opposite an inwardly projecting portion 14 of the other casing-section. Preferably v the projecting portions 14 of the casing are spaced substantially equidistantly circumferentially of the marking element, and said portions of the casing, the axis of the hinge formed by the strip 12, and the marking element are substantially parallel.

As shown in Figs. 1, 2 and 4, the sections A are locked together by a sleeve C shown closely embracing the forward end portion of the covering 12 and removable forwardly from the casing. 'Said sleeve has a forwardly tapering forward end portion 13 closely embracing the tapering forward end portion of the casing, and said taperingportion of the casing and said tapering portion of the sleeve cooperate in forming a sto for limiting rearward movement of'the s eeve.

As shown in Fig. 2, the inwardly projecting portions 14 of the sections A have such arrangement relative to the marking element that said portions of said sections exert enough pressure against the marking element to cause the marking element to be gripped by said casing-sections, and it will be observed that said portions of said secportion 14. of the inwardly tions are invaluable because they grip the marking element along lines extending longitudinally and spaced circumferentially of the marking element'so as to insure a uniform and eflicient holding of the marking element by said. casing-sections. The tapering portion 13 of the sleeve C is imperforate and rigid from end to end as shown, and said portion of said sleeve, by closely embracing the tapering forward end portion of the casing, insures an'efiicient locking of the sections A in their pressure-exerting relation to the marking element. The paste or substance employed in attaching the covering 12 to the sections A firmly secures all portion of the casing and so as to positively prevent fraying of the threads or fibers of or otherwise mutilating said covering at said end of the covering during the application of'the sleeve 0 to the casing. By the construction hereinbefore described it will be observed that the casing of my improved pencil has internal pressure-exerting portions14 which are formed on the sections A and spaced circumferentially of and efficiently grip without liability of breaking the marking element, and that said sections form the longitudinal walls of the passage- 7 for the marking element and are locked in the pressure-exerting relation to the marking. element of said pressure-exerting portions, as shown in Figs. 2 and 4, and relatively -movable, upon unlocking them by removing thesleeve C, to release the marking element. Fig. 3 illustrates the lead or marking element-as released and as lying in one of the casing sections A and shows the other casing-section swung open far enough to permit lifting of the marking element out of the casing and replacing it by another marking element, if desired, without necessitating movement of the marking element endwise of the casing.

What I claim is- 1. In a pencil, a marking element extending longitudinally of the pencil, a casing embracin the marking element and having a forwardly tapering forward end portion and divided longitudinally into sections having inwardly projecting portions which are spaced circumferentiallyv of and exert pressure against the markin element, a strip of flexible material, whic strip is arranged rearwardly of said tapering portion and extends circumferentially of the casing and forms a covering for and is attached to the casing-sections and hinges said sections together, and a sleeve embracing the forward end portion of said covering and having a forwardly tapering rigid forward portion which embraces said portion of the casing and participates in locking the casing-sections in their pressureexerting relation to the marking element, and the afore:

said inwardly projecting portions of the casing-sections extending longitudinally and to the forward end of said tapering portion of the casing.

2. In a pencil, a marking element extending longitudinally of the pencil, a casing embracing the marking element and having a forwardly tapering forward end portion and divided longitudinally into sections for gripping or holding the marking element, a strip of flexible fibrous material, which strip extendsrearwardly from said tapering portion and circumferentially of the casing and forms a covering for and is attached to the casing-sections and hinges said sections to gether," and a sleeve embracing the forward end portion and having a forwardly tapering forward portion embracing said portion of said covering of,the casing, said sleeve locking the casing-sections in their pressureexerting relation to the marking element, the aforesaid covering having its forward end reduced in thickness in the direction of the forward extremity of the pencil and having its outer circumferential surface flush at said end of the covering with the embracing the marking element and having a forwardly tapering forward end portion and divided longitudinally into sections and having inwardly projecting portions which extend longitudinally and rearwardly of said portion of the casing and are spaced circumferentially of and exert pressure against the marking element, and a strip of flexible material, which strip is attached to the casing-sections and arranged to effect the formation of a hinge-connection between said sections, and a sleeve having a forwardly tapering rigid forward portion which embraces said tapering portion of the casing and locking the casing-sections in their pressure-exerting relation to the marking element, the casing being thickest at and along the aforesaid inwardly projecting portions of the casing-sections.

In testimony whereof, I sign the foregoing specification, in the presence of two witnesses.

WILLIAM ROLL.
