MAGAZINE PENCIL.

Application led December 6, 1923. Serial No. 678,854.

To all 'whom z't may concern.:

Be it known that I, MAURICE ALLAND, a citizen of the United States, residing at Atlantic City, in the county of Atlantic and State of New Jersey, have invented certain new and useful Improvements in Magazine Pencils, of which the following is a specilication.

The object of this invention is to provide an improved pencil of the magazine type, wherein a store of the so-called leads is maintained for renewing the writing point, or that portion of a leadexposed for the purpose of writing.

Another object is to provide in such a pencil means, connected with the piece of lead being used, which is adapted to cooperate with other means Within the pencil casing, whereby the extent to which the lead i projects from said casing is automatically governed in accordance with predetermined details hereinafter set forth.

A further object is to provide such a pencil' with an elongated cylindrical eraser, means for operatively supporting said eraser, and means for actuating said supporting means, whereby when the exposed portion of the eraser is worn away the supporting means permits the cylindriform member to be withdrawn further, and then clamped so as' to prevent its accidental retreat into the pencil casing.

Withthese and other objects in view, the invention comprises additional novel4 details 'of construction and operation hereinafter fully brought out in the following description, when read in conjunction with the accompanying drawings, in which Fig. 1 is a longitudinal diametrical section of one embodiment of the present invention; Fig. 2 is an elevation of the same; Fig. 3 is a longitudinal section of the lower portion off the device showing the parts in different relative positions than that exhibitedJ in Fig. 1; F ig.l 4 is a transverse section on the line 4 4 of Fig. 2; Figs. 5 and 6 are transverse sections of the device as shown in Fig. 2, but at the respective points as indicated by the lines 5 5 and 6--6 on Fig.

1; Fig. 7 is a fragmentary elevation of the upper eraser-supporting portion of the de.- vice, with the clamping member removed; Fig. 8 is a fragmentary elevation of the i lead-supporting portion with the clamping lin Figs. 1 and 2, the fingers 6 are flexed member removed; and Fi 9 is 'an elevation 55 of the lead clamping mem er per se.

Referring to the drawings, a cylindrical casing 1 is provided, comprlsing a magazine for holding spare leads, saidcasing' being preferably enlarged at 1 and 2 and provided with a reduced end portion 3, which is provided with a bore 4K comprisinga continuation of the magazine chamber within the casing proper. Said end portion 3 is longitudinally cut at spaced regionsl 5 to provide intervening radially resilient ngers 6.

Said reduced portion is externally threaded adjacent to the enlarged portion 2 and is adapted to receive the internally threaded portion 7 of a clamping member 8, which is preferably knurled circumferentially at 9, and the inner surface of the walls of which preferably taper, `so that upon screwing said clamp into the position shownradially inwardly to .grip and secure against longitudinal movement a I cylindriform eraser 10. I

So far as the invention is concerned, it would be the equivalent of this construction to have the outer surfaces of the fingers 6 tapered, and the clamping member', provided internally with a shoulder or other cooperating portion which would operate in a similar manner to contract said fingers about the saideraser.

The opposite end portion of the casingfl is. internally threaded at 11, the inner end of which threading terminates adjacent to a planeshoulder 12. A second casing member 13 is provided with a reduced and externally threaded end portion 14, which engages the threads 11, and secures against the shoulder 12 the disc-like member 15, which is provided with a central bore 16 adapted to receive from the magazine section 1 a lead 17.

Secured to the member 15 and in axial alignment therewith is a tube 18, which terminates at 19 quite near to the lowerv open end of an enlarged extension 20 of the sec.-

extends beyond the lower limits of the first tube, is slotted at 23 to provide radially yielding fingers 24, and is externally threaded at 25, while the free end portions of said fingers are tapered at l26.

lt will be obvious from this construction' that when a lead 17 extends between the provided upon the interior of the' free end l fingers 24, a hollow conical member 27, in-

ternally threaded at 28 and providing it are radially compressed upon the outer surface of the latter.

lt should also be noted, by reference to Figs. 1 and 3, that the lead being used is provided with an encircling sleeve 30, pf light-weight metal and which. should frictionally engage the lead.` With this construction, aid the device in the arrangement lshown in Fig. 1, it is assumed that the ex'- posed point of the lead is worn away to the extent shown in Fig. 2, andthat y1t is desired to expose an additional amount .of lead.. c

rlhe clamping member 27 is separated` entirely from the lead-supporting fingers and is represented by the relationship between Figs. 8 and 9. An additional quarter-inch or thereabouts of the blunt lead will exposed, and which may be manually gripped by the fingers and pulled longitudinally outwardly as far as desired, as for instance to ythe extent of fonehalf, to a three-quartersinch.

During this action, the sleeve 3() im-y pinges againstradially aligned shoulders 31 portions of the contractable fingers 24. 'llhe clamping member 27 is thereupon screwed, as shown in Fig. 3, upon said fingers, that is, until it is slightly spaced from the casing member 13, of which it normally forms a continuation.

'lllfie ypencil with the protruding lead is then pressed gently upon any available surface 32V until the lead is forced upwardly into the casing, the sleeve 30 then imping.- ing upon the free end portion 19 of the tube 18, and sliding up the lead until the latterv comes to rest. v

Upon raising the pencil for cooperation with the said surface 32, and with the clamping member still loose, the lead is free to drop until the sleeve 30 rests upon the shoulders 31. Said clamping member then being rotated into the position shown in Figs. 1 and 2, the fingers 24 grip the lead and restrain it against its receding into the said casing. y

0bviously, this operation can be repeated as many times as necessary, until a given bar of ead is completely used, that is, has wasted away in writing. Thereupon the clamping member 8 is removed entirely neonata from the lingers 6 or at least until it is possible to remove the eraserlO, whereupon another of the leads 17 in the magazine may be extracted, the eraser and its clamping member replaced and the new leadslid into the fingers 24 and through the sleeve 30, whereupon the proper adjustment for writing purposes is thereby attained as hereinbeiore described.

Having thus described my invention, what l claim and desire to protect by Letters Fatent of the United States is 1. ln a pencil, the combination of a casing having an outlet, a. removable channelled magazine member within said casing providing a shoulder in the neighborhood of said outlet, a plurality of radially yielding fingers comprising a unitary part oit said casing and adapted to surround a lead extendingfrom said member and through said outlet, said fingers jointly having an enlarged bore terminating in a circumferential shoulder in one direction, a sleeve trictionall carried by a lead and movable within saidI bore between the limits set by said shoulders, to automatically predetermine the extent that the lead shall extend from said casing, an auxiliar member having an aperture through which the lead projects and provided with inner converging walls, and threaded means to Aremovably secure said last-named member upon 'and as a continuation of said casing, said ngers being contracted upon and operative to normally pre vent the inward movement of the lead as said last-namedA member is screwed upon said casing.

2. ln a pencil, the combination @of a casing closed at one end by a removable partition having an aperture, a second hollow casing removably secured to and operative to serve as a contmuation'of said firstpcasing and formlng a lead magazine, a tubular inember extending from said partition through saidl first casing towards its opposite end and terminating in a shoulder, a second tubular member connected .with'said first casing and surrounding said first tubular meinber and at its free end being longitudinally MMD slotted to provide radially yielding fingers M5 providing an inwardly directed shoulder and frictionally engaging a lead extending therethrough from within said first tubular member, and av sleeve adapted to surround a leadin frictional engagement therewith and having a longitudinal movement limited by said shoulders."

3; lln a pencil, the combination of a casing closed at one end by a removable partition having an aperture, a second hollow casing removably secured to and operative to serve as a continuation oit said first casing and forming a lead magazine, a tubular member extending lfrom said partition through said rstf casing towards its opposite end and at its free end .being longitudinally slotted4 to provide radiall yielding fingers provid` ing an inwardly irected shoulder 'and frictionally engagln a lead extending therethrough from wit in said first tubular member, a sleeve'adapted to surround a 'lead in frictional engagement therewith and having a longitudinal movement limited by said shoulders, and a hollow member having tapering inner walls and a central aperture through which a lead protrudes, said lastnamed member being adapted `to be screwed upon said fingers and form a continuation of vsaid first casing, to contract said lingers and thereby prevent an ,accidental inward lmovement of said lead. p
