To all 'whom 'it 'may concem:

Be it known that I, Cmrronn N. JOHNSON, a citizen of the United States, and a resident and State of Ohio, have made an Invention Appertaining to a Pencil, and I do hereby vdeclare the following to be a full, clear, and exact dethe invention, such as will enable'others skilled in the art to which it appertains to make and use the same, reference eing had to the accompanyingdrawings,

and to the characters of reference marked thereon, which form a part of this specification.

This invention relates to pencils and particularl to a magazine pencil of the type in whic a barrel and a tip member are respectively mounted for relative rota'ry movefitting one within the other and s aced from the barrel, one tube having a he ical and the other a longitudinally extendinv slot for receiving studs o ead actuating mechani'sm, whereby a relative turning of the tubes will impart propelling and repelling movements to a lead. The inner of said tubes is fixed to the tip member and the outer one to the barvrel to respectively turn therewith, and a corrugated magazine sleeve fits between and is adapted to turn in unison with the barrel and the outer slotted tube, the barrel being fixedly connected to the magazine sleeve and to the outer slotted tube.

The primary object of this invention is to utilize the spring or hook carrying fingerlike member of a pocket engaging clip to rigidly secure the -magazine sleeve off the pencil in assembled position within the barrel, and vice versa, whereby to simplify, cheapen and lquicken the manufacture 'of such pencils, wfacilitate repairs and enhance the practicabil'ty and commercial value thereof. z

The invention is fullyl described in the following specification,v and while in its broader aspect it iscapable of embodiment in la preferred embodiment thereof is illustrated in the accompan-ying drawings, in which Fig. 1 is a side elevation of a pencil emthe invention. Fig. 2 is a similar enlar'ged ,view thereof with portions broken away. Fig. 3 isl a fragmentaryvportion of Fig. 1 with the pocket engaging`-clip removed. Fig. 4 is a section' on the line '1 and tip 2, the latter f tached to the barrel 1,

for instance like or similar to that vthe inner side of contact in Fig. 2, and Figs. 5 and 6 are side and end views of the clip. Referring to the drawings, 1 and 2 respectively designate the relatively ro'tatable barrel and tip members of a pencil embodying the invention, 3 and 4 the outer and inner slotted tubes iitting, one within the other and spaced from the barrel, and 5 the corrugated magazme sleeve fittin'g between the outer slotted tube 3 and barrel 5. In the present instance the tube 3 is provided with a longitudinal slot and the tube 4 with a helical slot. Asho'rt bearing 6 is fixed .on the forward or inner end of the tube 3l and 'forms a bearing for the adjacent ends of the barrel having a turning fit thereon. The tube 4 is intended to project at the writing end of the pencil beyond the tube 3 and is fixedly connected to the tip 2 to turn therewith.

The pocket engaging is preferably of the lev'er ty e, disclose in U. S. Letters Patent No. 1,267,- 57 5 dated May 28, 1918, wherein the cli member is carried by a spring finger whic projects from the lever intermediate and thence through a hole in the side of the barrel or other part to which secured, the inner end portion of the spring lying along the barrel and being firmly held thereto by an inner plug or sleeve member within the barrel. It is not desired, however, to restrict thev present invention to the useof a clip of'this character for, so far as the invention is concerned, the barrel engaging spring finger, or other part of the clip m'ay be disposed at an end thereof intermediate'its-ends or in anyother suitable position. w g

In the present embodiment of the inven- ,tion the barrel enga ing member of the clip therefrom intermediate its ends through anl opening 9 in the side of the barrel 1 adjacent to its outer 'end and then extends along therewith and has its free end terminating in anv inwardly extending tall-4 piece or' portion 10 projectin toward the axis of the pencil and preferab y notched to receive the outer edge portion of one of the ribs of the corrugated-sleeve 5. 'Inasmuch as the magazine sleeve 5 is intended to fit clip 7, which is atthe inner side of the barrel to and in its ends w closely in the barrel 1, the portion of the barrel withinwhich the member 8 is disposed is slightly outwardly'offset to provide a space 11 between the magazine and barrel 1 for receiving said member. 'I`he rib of the magazine tube with which the member 8 engages vis provided with a notch 12 with which the angled end 10 of the member 8 has interlocking engagement when the parts are in assembled relation as shown in Fig. 4.

In assembling the parts'pof the pencil, it is found preferable in`p1'actice to vassemble all of the pencil parts with the exception of mounting the barrel on the magazine sleeve 52 which latter is soldered or other- Wise sultably fixed' on the slotted tube 3. A clip 7 is then placed in engagementwith the barrel by inserting its carrying finger or member 8 through the barrel opening 9 to position the clip in assembled position with respect to the barrel. The barrel is then forced over the magazine sleeve 5 until its inner end passes over the bearing collar 6 in substantially end abutment with the inner end of the tip member 2. In forcing the barrel over the magazine sleeve, care should be taken that the rib of the sleeve having the notch 12 therein is the one which has engagement with the notched tail-piece of the finger 8 'so that such tail-piece will spring into looking engagement with the notch 12 when the notchL is brought into register therewith." To facilitate forcing a rib of the magazine sleeve past the inwardly angled tail-piece of the clip carrying member 8; such tail-piece should be inclined away from the forward end of the barrel in the direction of insertion of the magazine therein, as shown. The outer end of the barrel 1 and magazine 5 are closed by a removable capmember 13 which is threaded to ya plug 14 projecting axiall'y from the outer end of the magazine sleeve.

It is evident that the interengaging of the tail-piece of the clip carrying member with a ribl of the looking of the barrel and magazine together so that a turning of the barrel will cause rotation to be communicated to the slotted tube 3 through the magazine, which is fixed to said tube. It is evident that this invcntion provides not only a simple means for securing the clip 'to a pencil barrel, but also materially fac-ilitates andfl cheapens the cost of assembling of the pencil parts.
