H. S. HASSELQUIST PENCIL Original Filed Aug. 14, 1920 ZEZ J Pw 0 jizz/@7360?? nd. The walls of the casing `xtremity are formed as at constricted passage through is projected for use. g the lower portion of the sleeve 16 whose lower end is he bushing. A plate 17 in the :her is adapted to rest upon the the sleeve so as to constitute s reserve lead magazine which, truction shown, is vdisposed ie upper region of the pencil nnular space intervening bells of the casing and the tube ice is subdivided by an elonne member B whose cross secesired, be that of a spider, such in Fig. 3. This construction le conveniently produced by a xtrusion provides, in effect a 19 from which radiate a plu- ;itions 20, the number of which ad as desired. The magazine dapted to be received within space surrounding the tube 11, rably secured against rotation ito, the hub 19 fitting over the walls extending to the inner asing. Tn this manner there is lurality of compartments each om the others, and each deie reception of a definite num- C. The' hub portion maybe of thickness to reduce the radial Neen the tube andthe casing rent undue play of the reserve 1. The radial walls are likerequisite vthickness to provde a th for each compartment which odate a predetermined number to the construction shown in 1d 1, the hub portion 19 of the imber is extended upwardly belial walls at which place, desigit is threaded; when assembled )encil body this projecting end ve the upper end of the pencil is designated by the number 22,

and useful lmprovemnts'Tn""i?e`ncns, Yor" which the following is a specification.

This invention relates to a pencil equipped with propelling mechanism interiorly of its body, and operable by means exteriorly thereof, for advancing into operative posi-- tion a lead at one end, and an eraser at the other. In many respects the present pencil follows the construction already disclosed in certain patents of Charles R. Keeran grant ed March 22, 1921, as Nos. 1,372,296 and 1,137 ,8541; it exhibits, however, certain improvements which have to do particularly with a magazine within the pencilv for the accommodation of reserve leads. Tt is to be understood, therefore, that the present pencil embodies a number of features claimed in the applications aforesaid, as well as certain other improvements to which specific reference will hereinafter be made.

In the accompanying drawing, an exemplification of vthis invention is shown in the manner following: l

Figure 1 is a longitudinal section through a tubular pencil body, certain of the intel rior parts being shown in eleva-tion;

Fig. 2 is a similar' view, enlarged, through the upper portion of the pencil;

Fig. 3 is a transverse section taken on line 3-3 of Fig. 2;

Fig. t is an elevation of the magazine member shown in Fig. 2; and

Fig. 5 is an enlarged detail in longitunal section ofthe upper end of the pencil showing a bushing arranged above the magazine member. Y

ln the use that is herein made of the terms upper and lower it is to be understood that l am referring to the pencil as it is pointed in use-that is, with the eraser end up, and the writing end down.

In Fig. 1 the pencil body, designated as A, is provided with a. lower end 10 which terminates bluntly in the form of a trun-v cated cone. ln the construction shown, this body may be produced from metal n tubular formation so as to provide a casing within which are accommodated the operating parts, as well as reserve leads. Ar-

ranged centrally within the body is a tube oe'sweateu o near its tip e at its lower e to provide a which a lead Surroundin tube 11 is a rested upon tl form of a was upper end of a base for the in the cons throughout tl within the a tween the wa 11. This sp: gated magazi tion may, if d as is shown which may b process of e: hub portion rality of part may be varfu member is a the annular f and is prefe; relative ther( tube and the face of the c1 provided a p separated fr signed fortl' ber of leads l the requisite distance bet' so as to prei leads thereii wise of the i circular leng will accomm of leads.

According Figs. 1, 2, a] magazine me yond the racY nated as 21, within the 1r also lies abo body which The central tube l1,however, extends slightly beyond the threaded end of the-member and and is flared outwardly as at 23 in overlying relation thereto so as to lixedlysecure the magazine member in place. 1A combined pencil head and magazine closure D 1s also provided which, as shown, consists of an eraser sleeve 24 and a rotatable collar 25 which may be l formed internally' with yan ,annular groove wherein is received a split ring 32 engaging also lwithin :a complementarygroove?) rformed exteriorly of a bushing uSel having extended walls 35 which con- :nect fast'withrthe eraser sleeve. By some l5 such means fas thisfarfreely rotatable connec- `tion may beiprovidedbetween the two parts iof the head. Afsecond bushing 26 is also :car 1ied fast in the lower; portion of the collar 4and is internally :threaded to: connectl to the upper end 2l of the magazine member. When arranged inplace upon thelpencil, as shown .in Figs. l and -5,\the walls of the collar: are z aligned with those 'of the casing fby a projection :22m of thel bushing 26 which extends withinthe casing ashort distance. Connected 1tast with` the eraser sleeve is -an :operating sleevef? disposed withiir the tube il land formed iwith l1screw threads `for en- :Uagingwit-h .ha threaded plunger 281 iadapted for Vnron-rotatable travel withinithepencil '.tube, the plunger being advanced or retracteedwwithfrotation of thef tube 11 throughthe vfinediumbi"the eraser1sleeve,to 4advance a aleadvor `an eraser iina manner Vsi-rnilarito that disclosedin theKeeran application alreatly referred to.

The 4connection between the tpencili head :zand body hrnay ibe .modified if desired, to italie the construction shown `in, Fig. I 40 have horefrepresented the upper endof the .magazine `member' 1 as 1 terminating slightly below thelfupperendf22f of the/pencil body.

Throughf the]` medium of threaids` formedi exiterierly on thefbushing: a connection isestablishetbwiththe collar bushing 26-so`that the head Dmay be detachably secured to the pencil.

`According tothe inventionithat I have herein described the partswhich form the l.magazine of this fpencillmaybe veryac- |`curatelyand expeditiously produced. lTheir assembly into the pencil may be accomplished with s fease i and precision. fllheL con- -`structi1on tis such `as torprovide -or anum- Vber of compartments eachlofwhichfmay accommodate .a =desired1-number of reserve" lleaidsiin suchY a anaainerasto prevent undue amotionitherein.
