Application filed September 25, 1'520. Serial No. 412,798. ARenewed October 31, 1925.

This invention rel; tes to magazine pencils and among its objects are to provide av simple, practical and comparative-ly inexpensive magazine pencil. Another object is to provide a magazine pencil having handle or case arranged to contain the internal parts of a fountain pen. Another obj ect is to provide novelmeans for feeding the lead out through the tip. Another object is to provide improved lead feeding means which may be readily attached to the handle or detached therefrom. Another object is to provide lead feeding mechanism Vvlgiich can be removed from the handle by direct endwise movement and the feed pin thereof brought to loading position under the influence of gravity. Other objects and advantages Will appear in the course of this specification and with all Aof said objects and advantages in view, this invention consists in the several novel features hereinafter fully set forth and more particularly defined in t-he claimsl The invention is clearly illustrated in the accompanying drawing, in which:

Fig. 1 is a side elevation of a. magazine pencilembodving a simple form of the present invention; Fig. 2 `is a side elevation partly bro-ken out to illustrate its inner construction; Fig. 3 is sideelevation of the pencil .tip andan associa-ted part; `.F 4l is aside elevation of certain members of the pencil lead feeding means; Fi 5 is a side elevation of a pencillead feeding pin; Fig. Gis a detail cross-section taken on the. line (Je of Fig. 2 and F ig. 7 is a detail cross-section talren on the line 7-7 of Fig. 2. Figs. 2 to 7 inclusive, are upon a greatly enlarged scale, to more cle-arly illustrate the construction of the pencil.

Referring to said drawing, the reference character 10 designates a handle or case Which may be in the form of a tube of ordinary'length to form a. convenient handle for the pencil. Said case or handlemay be .formedof hard rubber or other suitable material to `give the pencil a pleasing and attractive appearance. f y

Within the case 10 is secured a tubular handle member 11 which, if desired, may extend the full length of the handle or case. In said tubular member 11 is a centrally apertured Wall 12, which forms one end ofthe magazine 13, in which the lengths of lead are stored. For convenience in `=construen tion, said Wall is ixedly secured in place by a radially extending tongue 14C, formed oii the Wall 12, which tongue enters a slot 15 formed inthe Wall of the tubular member 11. As a preference, l form said tube 11 out of a strip of fiat material land form oppositely disposed notches in its side edges` which when brought together, (when the strip is rolled u a to form the tube) form the slot 15 for the reception of the tongue le.

.Centrally disposed in the magazine portion is a guide tube 16 for the lead feeding means. One end of said guide tube 16 is secured in the central aperture of the Wall 12, as for `instance lby forcing it into the aperl ture, and the other end is like-Wise secured in a strut or bar 17 which extends between the opposite Walls of the inner tube 11 near its outer open end.V The opposite side edges of the strut or bar 17 are curved as shown, and spaced away from the inner face of the inneil tube 11 to leave openings or passages 18 on opposite sides of the guide tube lthrough yvhich the lengths of'lead may be inserted into the magazine and removed therefrom. lt is to be understood that behind the strut or bar 17 the magazine voccupies the entire space around said 'uide tube 16, and that a large number of lengths of lead be stored therein.

Removably secured at the open end of magazine 13 is the conical tip 19 of the pencil, which may be formed ofthin metalhavinga central opening 20 at its smaller end, and formed with a reduced shouldered port-ion Q1 at its other end against 'which is vsecured 4a centrally aperturcd'end piece The reduced portion lits in the open end of the handle. A longitudinally slitted tube 223 is secured against rotation in the pencil tip 19 and said longitudinally 'slitted tube 9.3 Vp rojects beyond the end member of the tip and is adapted to extend into and be rotatively contained. in the guide tube 1G.

Movably contained in the slitted tube 23 is a tubular lead guiding member 24 which is formed, throughout a portionof its length, With a helical slot 25 through which projects ahead orbent end 2G of alead feeding pin 27, which is contained in the bore or central hole QSof the lead guidingmember 24. Thelead feeding pin 27 and bore 28 are approximately of the same diameter as the diameter of the lead,V enough clearance being left for the free 2 nenas?? movement oit the lead and pin. It desired, the outer end ot the lead guiding,` member Q4, that is to say the part which protrudes out through the small end ot the tip 19, may be slit lengthwise as at 29 and the opposite walls of the tube maybe bent slightly towards each other to forni a slight pressure or grip on the lead to thereby prevent it illi'oin accidentally dropping' out through the open end of the lead guiding; mei iber. @n the opposite end of the lead guiding' member 2&1 is secured a head or block 30 which is arranged to interlock with a block 31 V[ixedly secured against rotation at the inner end ot the `guide tube 1G. The block 31 may be formed with a tongue 32 adapted to enter a notch er slot 38 'loru'led in the outer end face oli the block 30. This arrangement -forms a. sort ol clutch mechanism between the spirally slotted lead guidingv tube and the handle 'for holding,l the lead `grinding' tube against rotation relative to the handle. The pencil tip, however, is free to turn in the open end ot the handle and the lengthwise slitted tube 23 is tree to turn withthe tip, and as will be presently described, relative rota- -tion between the tip and handle ellectuates the feeding,` of the lead out through the end ot the lead guiding' member 24;.

As illustrated in the drawing, the magazine 13 may be made comparatively short, but considerable space is aiorded in said niagazin-e around the guide tube 16 for the reception of leads. Said magazine may, however, be made to extend throughout the tull length ot the handle it desired, but l have found that by providing a short magazine in the handle, the remainder thereof may be used to receive the reservoir 34, and other operative parts ot a complete fountain pen construction 35, as is more fully set lorth in a companion application filed on even date herewith and given the Serial No. L112,7 97. TWhen the device is made to include the fountain pen construction, a removable cover 3G may be employed as is customary, to cover the pen or nib et the fountain pen.

In operation, the handle and tip are rotated relatively, as tor instance by taking hold ol the tip with one hand and the handle with the other and giving' one or the other a partial rotation in the proper direction, and the lead in the lead guiding member is thereby projected or led out through the open end thereol. Assuming that the tip is held stationary Yandthat the handle is rotated, it will be ob served that the lead guiding; n'ien'iber Qllis rotated through the instrumentality el its clutch connection with the handle, and that by reason ot the engagement ol" the head or bent end 2.6 of the lead lfeedingij pin 2T with theedg'es el the slot 23 oit the slitted' tube 23, which is held stationary withthe tip, said pin is kept from rotating' with the lead guiding tube, but because ot the engagement et the edge ot the helical groove in said lead guidin construction is possible wit-hout tube with the head of the pin the latter is moved longitudinally through the central bore ot the lead guiding member, towards the open end thereof, thereby moving the lengt-h et lead in front ol it out through the open end Till et the lead guiding member. Y 1

ivlhen the length olf lead has been used up, itmay be replaced by a length taken from the magazine ot the pencil. To replace the lead the tip is detached 'from the handle, thereby 7 uncovering the openings to Vthe magazine.. To detach the tip from the handle, it is pulled outward trom the handle in a direct, endwise or lengthwise movement, which requires but an instants time, the lead ,quitting member S0 i 2liis then withdrawn troni the slitted tube 2?), and when held in an upright position the lead feeding' pin is tree to gravitate to the lower end of the spiral slot. fi, length et lead may then be inserted into the end et the .95 lead guiding tube, the latter inserted into the slited tube with the head ot the pin entering' the slit thereof and the tip replaced on the handle. Then the parts are thus puttogether the clutch connection between the 9i" spirally sloted lead guiding tube 2e and handle is reestablished, and by rotating the handle relative te the tip, in the proper direction, the lead is ted out through the open end et the lead guiding tube. Y J5 lt is to be observed that the removable parts'el the lead feeding mechanism may be disconnected byV d-ircct endwise movement, which requires but a inoments time, and that when the spirally slotted lead guiding lll" tube and the member which prevents relative rotation Vbetween said helically slotted lead guiding tube and pin are disconnected by direct endwise movement, said lead feeding, pin is tree to gravitate' along the spiral slot. im

rlihe parts are simple in construction and by reason of the peculiar arrangement ofthe lead feeding mechanism much less time required to insert a new length et' lead than in any ot the magazine pencils now in common l il' use.

lt will be observed that by inaltino the lead Afeeding mechanism disconnectinle a' 'the tip portion olE the pencil, and by nialrin agi'- axine comparatively short, the ren under et lla the Vnandle may he'utiliL/.ed to con ain the internal members ot" a fountain pen, thereby making the case serve as al idle tor oath the pencil and fountain pen.
