Be it known that l, WILLIAM d; FLICK, a citizen. of the United Statesy residing at lllexandria, und State of Virginianl have invented certain new and useful .improvements in Pear cils, of which the following is a specification. f

y This invention relates to improvements in pencils of that type in which a supply of leeds .is contained in a magazine within the barrel of the pencil and the leudsarel sucessively positioned forv use and adapted to be fed from the pencil as they are Worn down, the general object' ef the invention being to provide a construction in which the leads will be accurately positioned, 'when renewal becomes necessary thus obviating the necessity of individually inserting the leads into the barrel of the pencil as in ordinary constructions.

' .Another object of the invention is to provide a pencil of the class mentioned above in which the magazine will not require to be lfilled with a supply 'of leads but on the other hand may in itself constitute an origina-l' container for the leads and be introduced directly into the barrel in place of" an emp-- tied maga-zine thus obviating the necessity of removingthe leads from a separate container and arranging them in a permanent magazine.

in the accornpenying drawings: l 'Figi/1re 1 is an axial sectional vica' through a penoil embodying the invention; NdFigure 2 is a. side elevation of the member provided for feeding the lead follower of the pencil; v

Figure 3 is a detail transverse View on the line Figure d is a perspective ric v .illustrating a modified form of the inag Figure 5 is a similar View nrustrutiiig another modified forni of magazine; vand Figure 6 is an end elevation oi the' body of ythe magazine shown in Figure 5. The pencil embodies a barrel which is indicated in general by the numeral 1 and which maybe in the nature olf an integral or one' piece tubular body or made up ol inner and outer tubular sectiinisv but in any event is exterior-ly'reduced in diameter at one endas indicated by the numeral 2. 'finto this end of the barrel 1. is tted the cylindrical inner end portion o. a. i'errulc i or tip which is indicated by the numerali sectional in the county o Alexandria' 'guide 5 nxed at ple to permit ofthe removal of with the barrel, l vWillfirst .means provided Vclearly shown in .Figure 1.-

i and'which is tapered substantially to a point as is usual in the corresponding elements of other pencils of this type. The ferrule is provided interi-orly with 'a tubular lead one end Within the minor end of the bodyof the ferrule and at its rear end Within any suitable manner within the major end of the tapered portion of the ferrule body. The ferrule is fitted friotionally onto. the reduced end of the barrel 1 and may be removed when occasion requires as for exam; an emptied magazine and the substitution of a filled a disk' 6 which is fixed in' u magazine, and the tubular member 5 of the ferrule constitutes a guide for theactive lead Awhich has been fed from the magazine and which indicated bythe numeral 7;

Before proceeding to a description of the magazine which is employed in connection describe the for feeding the active lead from time .to time as it is worn down. "Varions Jfeeding means may be employed but the one preferred and which is 4shown the at one end is rotatably fitted Within an Openf' ing 13 formed in a bushing 14 which is fixed Within-the barrel 1 of the pencil at a point suitably spaced from-the forward en d of the said barrel, the said end of the tube 12 being preferably over turnedl or as to .res-train it awainst longitudinal*` displacement within tie bush permit of its rotation .Within said bushing. The opposite end of :the tube is fixed in any suitablevinanner in a head 16 which isprovided 'with a reduced portion 17 'rotatably fitting in the rear or barrel 1, the said head 16 being preferably provided with a ciroumscribilg bead l18 to abut against thev said' end of the barrel as lf desired the head 16 may be providedwitl aa'eraser tip indicated by the -numeral 19, and in' thisvevent a cap20 will be -frictionally fitted onto firmly bind the head ing 14 and yet" butt end of the movement The tube 12 isuformeduwith drawings comprises a follower which is indi-` a longitudinally extending slot 2l through which the lug 1l. projects, and the end of this lug projects intoa helical slot 22 formed in the wall of a tubular feeding ineinber 23 5 which rotatably receives the tube l2, and is anchored at its forward end in the brshing le so-that it is `fixed with relation to said bushing' and to thejbarrel. lt will new be evident that upon rotating the tube i2 .to through the instrumentality of the cap 2O or by holding the cap stationary and rotating the barrel, the lug ll. will be caused to travel in the helical slot 22 in the 'feeding tube 23 thus .advancing or retracting the tol 'to lower 8 and thus provide for adjustment of the active lead 7. Thus whenjthe follower is advanced, the active lead will be ted through the tubular guide 5 and to'project a suitable distance beyond the minor endot the terrule 2o d for writing purposes and after the lead has been exhausted and it is desired to bring a new lead into place from the magazine, the tollower may be retracted by.. relatively rotating the barrel l and cap '1'n the manner previ- -425 ously explained.

K The magazine of the-pencil may assume various forms and be variously constructed but in general its exterior surface will de scribe substantially a cylinder and it will be 3@ oie such dirnensionsas to adapt it to be re- 'niovably and yet-snugly titte-d into the 'fori ward end of the barrel l. The magazine, in that forno of the invention illustrated in Figure 1 of the drawings, is indicated in 355 general by the numeral 24: and the seine comprisesa hollow cylindrical body which vas stated is exteriorly of `a dia1neter to adapt it to 'be fitted snugly and yetrernovabli, withlinthe forward end of the barrel, and

t@ when 'iitted Iinto place its vinner end willv abut against the bushing lll, and its outer end portion will project a short distance be yond the end of the barrel and seat against the disk partition 6 within the errule l when the said errule is in pla. ln this manner the magazine is vrestrained against longitudinalldisplaceinent and held improperly centered position. ln all forms ci:l the invention the vmagazine is provided with a lead receiving chamber ot substantially convolute forni, and in providing this chamber,

' in the forni of the invention shown in Fig;-

ures l and 3, alwall nier/ber 26 ot-sheet metal is secured valong; one edge to the inner surface ofthe wall ot the .cylindrical body 25 of the magazine 'and extends inwardlyaand is turned back upon ltseliLe as at 27 so *that on the whole it constitut s substantially a convolute partitionv wall""naving one edge united to the wall ofthe body 25and the other edge spaced roin thewall of said escasos pencil, this channel will register at one end with the bore oi' the tube 12 and at its other end with the bdre ot' the tube 5, and therefore a lead lodged within the channel or pocket will be in axial `alinenient with the bore ot the tube 5 and, when the follower stein 9 is At'ed longitudinally through the said channel 28, the'lead Awill be ejected from the `channel and through the said tube 5. The

advance the follower stein 9 and thus feed the lead '7 which is at that time within the, channel .or pocket 28 outwardly through the tube 5.u'ntil it projects a suitable distance beyond the minor end ot theA furrule 4f. widhen this lead has been exhausted or sub stantially exhausted and it becomes necessary, to bring new lead into position for use, the barrel' -l is rotated with relation to the cap- 20, or 'vice' versa as may be preferred, until the follower stem -9 has been retracted to the fullest extent and has completely' cleared the channel or pocket 28. The barrel of the pencil is .then given a backward rotative movement so as to influence the next lead in position to roll over the edge ot the partition wall 2d and drop into the channel or pocket 28. The follower stemt) may then be adjusted so as' to 'feed the newly positioned lead as occasion requires.

.it rnodied 'torni ct magazine is illustrated in Figure i ci the drawings and'is indicated in general by the numeral 29 and the body of this magazine is preferably formed from e single integral blank ot sheetinetai rolled ics l yilo upon 'itself toprovide a cylindrical wall 30 l and a partition wall portion 3l which constitutes an integral continuation from one cap .members being to close the ends of the magazine and to retain the leads in place and thus adapt the magazine to serve inlbody. ln this mannerv thereis provided a\ tially as a dispensing container for the leads,

both caps being 'removed and dlscarded at channelor pocket 28 extending yaxiallywithl in' the body 25 of the magazine and when the 55' magazine is fitted-into the barrel Il. o' the the' time the magazine is to be fitted into the @first preparmg a Maase:

Figures 5 and 6 of the drawings illustrate anat-hei' modified form of magazine indicated in general by thenumeral 33 and the body of this magazine ma be formedbi flattenel tubular bla and their rolling the lo nkto convolute form so as to provide a convolute lead chamberv as `in the previousl' descbedforms' and which chamber is'in icated by the numeral, 34'.

ln thisl form also the endsj-{of` the body of of the vconvolute lead chamber will ybe inv alinementv with the axis of the pencil barrel and one of theleads will bein position for ejectment through the ferrule 4.

Having thus described the invention, what is claimed as new is:

1. In a pencil, a barrel having a magazine receiving chamber in its forward portion, e ferrule removably tted to the said portion ofthe barrel and having ends of its body, it4 barrel of the pencil a lead channel in axial alinement with the barrel, 'a lead follower movable in alinement with thesaid channel, means for adjusting the-follower, and a lead magazine removably disposed within'the magazine receiving'chamber of the barrel and confined therewithin by the said ferrule, .the said magazine having' a convolute lead of the convolution of which is in alinement with the follower and the said channel.

2. In a pencil, a barrel having a ymagazine receiving chamber in its forward portion,"

chamber the inner portion a ferrule removably .fitted to the said portion of the barrel and having a ,lead channel, a lead follower movable in -alinement with the said channel,means for adjusting the lfollower, and a-leadmagazine comprislng a.

convolte lead chamber the p body having a inner portion 4of the convolution of which is in alinement with .the longitudinal axis of the body, and removable means initially closing the ends of the body and the chamber therein whereby. the magazine may initially constitute an original package for the supplyl of leads and,l upon removal of the closure means, may constitutean open ended magazine for removable insertion into beiI' in the barrelh. ,f1 m n n testimon w ereo a xm -WILIAM signature.
