IAGAZIN E PENCIL.

Application led September 16, 1822. Serial No. 588,594.

To all whom it may ncem.' y

Be it known that I, FREDERICK W. HEINZ- MAN, a citizen of the United States, and a resident of Jersey Cit in the county of Hudson and State 'of ew Jersey, have invented certain newv and.,useful Im rovements in Magazine Pencils, of whic the following is a specification, reference being made to the accompanying drawings, forming a part thereof. l

My invention `relates to ma azine-pencils designed to hold a plurality o reserve leads which may betaken from the magazine and brought into operative position in the pencil when desired, and also 'to that type in which there is also embodied in the pencil a leadpropelling and retracting movement actu'- ated by a rotatable head on the casingbody of the pencil. v-

The objectsvof my invention are, Aamong other things, to provide a simple, compact and elicient pencil of this character having a minimum. of working parts which are also capable of ready detachability from one anr other so that such working parts comprising the movement may be disassembled b the user and new parts may easily be rep aced should any of such parts become worn or broken, coupled with Ameans to adjust the tension between the lead carrier and the spirally-grooved tube or feed operating member so that the lead along with its carrier when advanced into operative position may not be pushed back into the casing by pressure on the lead oint when in use. Another object of my invention is to provide a removable eraser cap mounted upon art of the pencil which cap actsto hol t e reserve leads in themagazme.

Other and fiu'ther improvements and advantages will be hereinafter set forth and particularly pointed out in the appended claims.

A preferred embodiment of my inventionis illustrated in the accompanying drawings in which-'- Fig.- 1 is aside view partly in section showing the arrangement of the parts comprising the movement; 4 y

Fig. 2 is a longitudinal sectional view of the pencil; and Y Fig. 3 is a composite side view vof various parts of the movement showing their relationship when disassembled.

Similar numerals refer to similar parts throughout the several figures.

Referring to Fi 1 and 2, the outer casing 4 constitutes t e cylindrical body of the pencil having the conical nozzle 5 terminating in the opening 6 throu h which the lead 7 projectswhen advanc into operative position by the pro elling movement. The lead 7 is held in the ead carrier 8 longitudinally slotted at 9, such carrier 8 sliding freely in the exteriorly threaded guide tube 10 which is longitudinally slotted in the usual manner. The guide tube 10 is secured to the magazine barrel 11b the pin 12 as. shown in Fig. 2, such barre being adapted to hold the reserve leads (not shown). The

upper end of the barrel is interiorly threaded at 13 to hold the cap 14 to which is affixed 'the eraser 15. Surrounding the guidetube 10 is the spirally grooved tube or feed operating member 16 which is crimped at its upper end to the cylindrical sleeve 17 vwhich encircles the barrel 11 inside the casing 4; the outer end ofthe sleeve 17 carries the operating head 18, all as shown in Fig. 2. Within the lead carrier 8 is the sliding ejector pin 19 having its forward end bearing against the rear end of the lead 7 as shown in Fig. 2. To the inner end of the lead carrier 8 is aixed the stud 20 which projects through the slotted guide tube 10 relatively to each other will cause the lead 'l carrier 8 and ejectorpin 19 to advance or retract within the casing 4 in the usual lx'nanner according to the direction of rotation. The ide tube 10I has the notch 23 cut therein (Fig. 3) into which the stud 20 falls to act as a stop to prevent undue advancement of the lead carrier 8 and also to enable the ejector pin 19 to further advance through the carrier 8 to force the stub end of the `lead 7 from the carrier'. The outer end of the guide tube 10 carries the cap 24 to prevent any of the reserve leads carried in the barrel 11 from being broken by falling .f into the open end of the tube 10.

To enable these operative parts of the lead propelling and ejecting movement to be held in position as well as to be readily disassembled, I have provided the following mechanism: Slidin over the outer end of the tube is the c utch 25 havin its base split at 26 and outwardly knurle at 27 to form a close fit within the casing 4 and the clutch 25 is held to such casing 4. The outer V end of the boreof the clutch 25 carries the inwardly projectin pin 28 which engages the notch 2.3 (Fig. 3 1n the tip of the tug-be 10 when the clutch is pressed down on the tube 10 to lock the clutch 25 with the tube 16. The

nut 30 is screwed on the threaded end of ...the tube 10 to hold the clutch 25 in position with the tube 16 against the shoulder 29.

nut 30 when screwed further down on the tube 10 forces the clutch 25 inwardly and an adjusting means for regulating the tension between the lead carrier 8 and the propelling tube 16 in their frictional engagement with each other.

Vlhen it becomes necessary or desirable v`to'replace any of the working parts of the 'end of the spiral groove 21, and the tails without departing from the princip lead-actuating mechanism before described, the movement proper is taken out of the casingei andthe nut 30 is unscrewed from the tu 10 sothat the clutch 25 may be removed from the lower end of the. tube 16, Relative rotation between. the two .

tubes

10 and 16 will advance the carrier 8 and ejector pin 19 so that their

respective studs

20 and 22 will emerge from engagement with the lower ar s may be separated as shown in Fig. 3. pon

reassemblmg the stud 22 first engages with y the spiral groove 21 and upon the next revolution of the tube 16 with the stud 20 so that the spaced relationship shown in Fig. 2 ma be maintained. The clutch 25 1s thenv orced down on the tube 10 and rotated until the pin 28 enters into the notch 23; thereafter the nut 30 is screwed down on the end of the tube 10 and holds the clutch 25 in operative osition against the outer end of the pro e ling tube 16.

I have s own and described a preferred and satisfactory embodiment` of my invention, but various changes and modifications may be made in the construction of the de and scope thereof as defined in the appen ed claims.
