MAGAZINE PENCIL Application filed November This invention is directed to an improvement in magazine pencils wherein a lead, stored within a magazine in the end oi" the pencil, may be selected, withdrawn from 5 the magazine, and delivered into writing position without separation of the pencil parts.

he primary object of the present invention is theprovision of a magazine pencil wherein a plurality of magazines are arranged, each adapted to contain leads for use with thepencil, with the leads of one magazine differing in Color from the leads of the other magazines, together with means which, through proper manipulation and without separation of the pencil parts, may be operated to select a lead from any desired magazine and introduce it into writing position in the pencil for use.

A further object of the invention is the provision of means by which a lead, in writing position in the pencil, may be readily and conveniently returned to its magazine and another lead selected and introduced into writing position in the pencil without separation of pencil parts.

`ln general structure, the improved magazine pencil includes a barrel formed at one end withmeans whereby the lead may be gripped and held in writing' relation to the barrel, the barrel above the gripping clemcnts being formed with a central channel in alignment with the gripping elements and with an annular series of independent channels, eachV adapted to contain a lead with the colors.

Mounted for rotation w'th respect to the barrel and held Vagainst other than rotative movement is a selector containing a. receiv- 'G ing channel which is at all times aligned with the centra-l channel in the barrel. The selector is also formed with a radially extending recesscommunicating with the central channel and adapted under proper rotative movement of the selector to register with any of the annular nels in the barrel.

llhen desiring to introduce a lead Vinto writing position in the pencil, the selector is rotated to align the radial recess therein 5 respective leads preferably of different lead carrying chan-V 1, 1929. Serial No. 404,130.

with the lead receiving channel containing the selected lead, the pencil is inverted and the lead in the selected lead receiving channel will slide down into the radial recess in the selector and when the pencil is returned to a horizontalposition, such lead will find its way into the central channel of the selector in line with the main channel in the barrel. The pencil is then held in an upright position permitting` the selected lead to move through and into the grippingelcments in the barrel where it may be held by the tightening of such elements tor writing purposes.

By a mere obvious reverse ol this operation, the selected lead may be returned to its proper lead receiving channel and any other lead in the pencil selected and positioned for subsequent'use.

rlhe pencil structure involves indicating means by which the particular lead to Vbe selected may be readily determined, both in manipulating the pencil to use such selected lead and in returning said selected lead to its respective channel for storage after use.

The invention is illustrated in the accompanying drawings, in which:

rlhe improved magazine pencil includes a barrel l of hollow construction, closed at the lower end by aV plug 2, axially ot which formed a channel 3 of a` size -to permit :tree passage of the selected leads therethrough. Beyond the barrel the plug 2 is formed with `the carrier.

more or less resilient gripping fingers l of approximately semicircular 'term in cross section to perniiit the passage et the lead between them.

l clamping element 5 is arranged 'for threaded connectie-n with the plug 2 ancL of taperci torni beyond the plug, the tree end ot the clamping clement encircling tl e gripping` lingers and 'termed in one position oit theclamping` clement to clamp the gripping iiiigers into the read to hold it for Writing purposes, and in the ther position ot such clamping` element to relieve the pressure on the gripping fingers and i'ree the lead for indrniendent movement. 'E his manner oi' holding tl e lead in or releasing' it from Writin` position is quite conventional and while the,

, iaefl means is preferred, it is to be understood that anv desired means for clamping and releasing' the lead may be used, as the present invention is not particularly concerned with this detail.

vWithin the barrel 1 and extending' from the upper surface of the plug 2 toward but materially short ot the upper end of the barrel is a lead carrier (i. This carrier, which may be in the iorm of a cylindrical plug frictionally held Within the barrel, is formed with a central channel 7, hereinafter termed the main channel, and Which When the carrier is in position, is in direct alignment- With the central channel 3 ot the plug 2.

Surrounding the main channel of the carrier is a series ot lead channels, hereinafter termed lead pockets and indicated at These lead pockets may, if desired, be formed by longitudinally recessing the outer surface of the carrier the outer Wall oit'. each pocket thus formed Wil be provided by the barrel 1. (if course, the lead pockets may oe 'formed by appropriately boring` the carrier, the sole requirement in this particular' being that the lead pockets be arranged in a row concentric with and spaced from the main channel 7 of the carrier. Y

The upper end ot the barrel beyond the lead carrier is enteriorly 'termed to indicate the character oi. lead in each lead pocket ot' lt, contemplated, these respective leads are to be distinguished by color, then the exterior ot the surface of the pencil in the part referred to will have a series oi longitudinally arranged spaced areas, each in the longitudinal plane ot a particular and each colored to indicate the color of the lead occupying that pocket. Thesevcolor indicators may, ot course, be of any distinguishing characteristic and are indicated at 9.

Fitting over the area oi the barrel on which the respective lead indicators 9 are placed is a ferrule 10, in the form of an elongated sleeve which is so connected to the barrel as toY permit free rotation of the `terrule Without pe-rmittingrelative longitudinal movement. The viferrule is formed with an opening 11 through which the respective lead indications 9 are visible as the ferrule rotated, thus perniittine,` the user to arrange the fcrrule in a particular relation to a selected color or other lead indicator, tor a purpose which will later appear.

Secured within the ferrule is what may be termed a lead selector.' 12. This selector inav be in the Jform ol a cylindrical block hai'- injaj a diameter slifrhtly less than that of the inte" "or diameter nii the barrel and a length permitting` the iree end of the select: to ltcrininate immediately adjacent the upper end ot the lead carrier when the parts are in lation. Thus, the selector is ot such length to till the barrel beyond the lead carrier, the selector ot course extending' beyond the barrel and being connected to the lierrule that, on rotation of the lierrule, the selector Will be correspondingly moved.

The selector is formed With a. central bore 13 which, when the parts are assembled, is in direct alignment with the main channel 7 oi the lead carrier and the central channel 3 ot' the plug 2. The bore 13 is closed by the ferrule or at the ferrule end ot the selector and open at the end of the selector, next the lead carrier. The selector is also formed with a radially arranged opening lll in the form of a longitudinally Xtending slot Which at its inner end communicates With the bore 13 and preferably 'opens at its outer end through the outer surface of the selector.

lt is, of course, to be understood that, asi de from the bore 13 and slot 14, the end ot the selector next the lead carrier is solid and forms an abutment to prevent endWise movement of the leads in the pockets when the pencil is inverted unless the slot is aligned with the particular pocket. It is o'll course understood that the lead pockets and channel in the lead carrier and the bore and slot in the selector are of suoli diameter relative to that ol the leads employed as to pern'iit rather tree movement oi" the leads While ot course preventing any appreciable inclined or tilted position ot the leads.

.Assuming it is desired to use a red lead in the pencil, the 'errule is turned until the red lead indicator 9 is displayed, through the openingv 11 in the Jcrrule. In this position ot' "he parte, the slot 14 of the selector in line "ith the pocket 8 containing the red lead, he pencil is then inverted and the red lead rein the pocket 3 moves longitudinally from pocket and into the slot 14rin the selector.

said The pencil is then returned to a substantially horizontal position and the red lead moves ifi-om the slot 14 into the bore 13 of the selector.

The pencil is then turned into a vertical or normal Writing position and the red lead in the bore 13 of the selector moves through the main channel 7 of the lead carrier through the central channel 3 of the plug 2 and belead or of housing the particular lead, the

clamping element is loosened and the pencll inverted. The lead moves from between the gripping lingers 4 longitudinally Vbetween the channels 3 and 7 and into the bore 13 of the selector. The selector is then turned to align the bore 13 with the pocket 8 in Which the lead is to be replaced. The pencil is arranged in a horizontal position With the slot 14 downwardly, the red lead passes .from the bore 13 of the selector into the slot 14 and as this slot 14 has been aligned with the pocket 8 into which the lead is to be replaced, a simple movement of the pencil into a normal or substantially Writing position causes the lead to move from the slot 14 into its particular pocket.

The selector may then be operated to select and position for Writing any other lead or .tor Within the i'errule, said selector may be the ferrule may be turned so that the opening 11 does not show any lead indicating mark 9. In this position, the slot 14 Will be out of alignment With any one. lead pocket and the leads of all the pockets will be prevented from endwise movement, no matter What the position of the pencil may be. rfhe end of the ferrule may be provide with an eraser 15 and the pencil may be further provided With the usual retaining c lip 16V and Where a clip is used, it is preferredthat the clip be formed with an opening 17 to reg-V ister with the opening 11 in the ferrule, so that the lead indicating marks` 9 will be visible through the clip.

While the pencil is primarily designed as a magazine pencil for containing leads of different colors, it will be appreciated that it Will be equally serviceable for different leads i of the same color but of dilferent degrees of hardness or even of leads which are identical in color and hardness, for With leads of the same color but of different degrees of hardness, the selection permitted Will enable the user to select the desired lead, While with leads of similar color and similar hardness, the pencil permits a convenient and simple renewal of a lead from time to time as may be required.

Gf course, it is understood that the pencil may be made of different materials and exteriorly ornamented to any desire-d degree and in any particulars, thereby providing a magazine pencil which, when once charged, will permit the user to select the desired lead and readily and convenientlyvplace the same in position for Writing'without the necessity of separating any parts of the pencil or directly handling the lead.`

The above description is illustrative of the y gers 4.

novel features of the improved magazine pencil and for commercial reasons it is preferred to indicate certain details Which simplify the construction and insure a more perfeet operation for the feeding of the lead. F or example, as shown in the preferred form, the channel 7 in the lead carrier, the channel 3 in the `plug 2 and the gripping lingers 4 may be constructed of a single tube-like element fitted tightly in the lonfritudinal axial opening in the lead carrier` 6, so that beyond vthe selector there is al single unbroken tube through which the lead may pass freely Without possibility of obstruction.

In the modified-form, this lead tube, here `indicated at .18, may be carried directly by the selector, here indicated at 19, but Which is constructed identically With the selector previously described. y This tube 18 is a continuationV of the bore 13 of the selector and of course passes loosely through the axial opening ofthe lead carrier, through the plug andV is Aterminally formed Furthermore, in the mounting-of the selecformed at the end remote from the lead car- Yrier With a pocket to` receive theeraser and With an exterior `fixed band 2() on which the ferrule proper is threaded, thus uniting the ferrule and selector for simultaneous rotative movement While permitting the selector 4to fit Within the barrel and the ferrule to pass the ferrule'and thereby the selector maybe Y accurately centered in any'adjustment ,relative t`o the lead pocket and held against casual relative movement during the use of the pencil.

It is to-be noted that the selector 12 is in Vthe form of a hollow cylinder which is closed at the end next the lead carrier but open at the opposite end. 4The interior of the cylindcr is fullyunobstructed except for the Wall detining thecentral bore land slot 14. This providesa very considerable area Within the selector freely accessible Vfrom the upper end of the pencil, which area is designed to serve as a storage space for auxiliary leads for the convenient recharging of the lead pockets of the carrier when necessary. The open end ofthe storage compartment of the selector is designed to be closed by the eraser, as clearly shown in Figures 1 and 5, so that by simply removing the eraser, the auxiliary leads in the vstorage chamber may be'removed for recharging of the leadpoclrets of the carrier.
