MAGAZINE-FENCIL.

Patented Feb. 11, 1908.

To all whom it may concern;

Be 1t known that I, WALTER F. OUsHING,

a citizen of the United States, residing at Bismarck, in the county of Burleigh and State of North Dakota, have invented certain new and useful Improvements in Magazine- Pencils, of which the following is a specification.

My invention relates to an improvement in magazine pencils, and the object is to rovide a very light, simple device of tri ing cost 'to manufacture, and durable and eflicient for the purpose for which it is designed.

With the foregoing objects in view, my in- .lead and holding it in the end of -t e inner tube or cylinder.

It further consists in a specially constructed sharpener for the lead which sharpener forms a cap for the pencil when in place ,thereon and serves the secondary function spreading.

My invention further consists in certain novel features of construction and combinations of parts which will-be hereinafter described and pointed out in the claims.

In the accompanying drawings: Figure 1 is a longitudinal, sectional view through the magazine pencil. Fig; 2 is a top plan'view. Figs. 3, 4 5 and 6 are details.

A, represents the barrel of. the pencil of preventing the split portion thereof from which is preferably made of thin metal cylindrical in form and of a length to suit the requirements, tapering at the forward end as at 1, and made solid within this tapering end to secure suitable and lateral sup-.

port at that point for the lead 2. This outer tube is provided with a hair line slot or slit 3 which extends from the rear end some distande toward the opposite end but preferably leaving a solid cylindrical POItlODbG- tween its inner end and the point of the tube as shown, to be grip ed between the thumb and fingers. One s1 e of this hair line slit or spring 9.

slot is straight'and the other is provided with diagonally disposed notches or ratchet teeth 4.

The barrel is open at the end opposite from the point and a cylindrical tube or carrier 5 of suitable length is fitted to slide in the barrel. In one end of this tube or cylinder the lead 2 is removably gripped by means of a truncated rubber. cone 7 the special function of which rubber cone is that it holds the lead t ghtly in place but affords sufficient elas-- ticity to permit it to yield as necessity requires and especially gives greater freedom for the longitudinal movement of the lead when 1n use, thus avoiding the danger of breakage at this point, which is likely to result from too rigid a clam as by metal, which ultimatelycauses the ead toerode resulting in its falling out, but the rubber gives a tight grip while permitting it to yield sufli ciently for all purposes and the grasp may be tightened by simply forcing the cone f urther.

in place. v

At the opposite end of the tube or carrier .the thumb piece 8 is formed upon a fiat steel. This spring is very thin, and sets slightly diagonal, its function being to slide through the slit of the barrel and spring into the nearest notch automatically, thus holding the lead in place andpermitting-it to be fed forward as it wears and is re-sharpened.

To remove the tube or carrier with any remaining unused lead, the thumb iece is slightlytwisted and the spring 9 parallel with the straight edge of the slit or slot in the barrel, whereupon the carrier with the-lead is capable .of being removed'from the barrel with perfect case.

A cap (I is adapted to be held frictionallg upon the end ofthe barrel. This cap pre "erably carries an eraser 10, at its outer end,-

rought I and pencil sharpener '1 1, at its inner end, and

it has, consequently, the function of holding the slit upon the end of the barrel A closed, while guarding the sharpener when thus in place.

being-set in thesharpener so that the sharpener projects into the barrel of the pencil The sharpener consists of a small steel knife cast in lead or other metal, diagonally to the slant-or the point cone, said cone when not in use, giving it a small and compact form and protecting the sharpener.

The special merits of my improved pencil will be' readily understood from the foregoing description, but in conclusion, it might be mentioned that it designed to carry a single lead, thus reducing the weight to a minimum and preventing annoyance of rattling so common to pencils of the magazine type, when in use; it is very simple in con: struction, and the cost-of manufacture is trifling. Thegbarrel has comparatively few notches and these are started -far enough one or more notches.

. or other extraneous matter.

\ the lead to break, even if it should strike point down.

Slight changes might obviously be 'made in the form and arrangement of the various.

parts described without departingfrom the spirit and scope of my invention, and hence I do not wish to limit myself to" the exact construction herein set forth but,

I Having fully described my invention,

what I claim as new and desire to Letters Patent, is:

secure by 1. As an article of manufacture, a magazine pencil comprising a barrel having an open slot extending lengthwise thereof, said slot having one notched edge, a removable lead carrier fitting the bore of the barrel and adapted to be slid therein, a thin spring secured to the carrier at a point remote from the slot in the barrel, said spring set diagonally whereby normally to engage the notches on. the edge of the slot, a. thumb piece secured to -the outer end of the spring, the spring being sufficiently yielding so, that a lateral twist of the thumb piece will, remove it from the notched edge of the slot.

2-. As an article of manufacture, a magazine pencil comprising a barrel having an 0 en slot extending lengthwise thereof, said s ot having one notched edge, a removable lead carrier fitting the bore'of the barrel and adapted to be slid therein, a thin spring sefcured to the carrier at a point remote from the slot in the barrel, said spring set diagonally whereby normally to engage the notches on the edge of the slot, a thumb piece secured to the outer end of the spring, the sprin being sufiiciently yielding so that a later twist of the thumb piece will remove it from the notched edge of the slot, and aremovable cap for closing the open end of the slot in the barrel.

3. As an article of manufacture, a magazine pencil comprising a barrel. having an open slot extending lengthwise thereof, said slot having one notched edge, a removable lead carrier fitting the bore of the barrel and adapted to be slid therein, a thin spring secured to the carrier at a point remote from the slot in the barrel, said spring set diagonally whereby normally to engage the notches on the-edge of the slot, a thumb piece secured to the outer end of the spring, the spring being sufliciently yielding so that a lateral twist of the thumb piece will remove it from the notched edge of the slot,

and a. removable cap for closing the open end of the slot in'the barrel, said cap car-- rying a pencil sharpener at one end and an eraser at the other. A

4. As .an article of manufacture, a magazine pencil having a tapering slot at one end to afford lateral support for the lead, and a rubber cone for clutching and holding the lead at its opposite end.

5. In a magazine pencil, the combination with a barrel, of a carrier fitted to slide there: in and a cone of soft elastic material adapted to carry the lead attached to the carrier.

6. The combination with a barrel having a narrow slot extending throughout a portion of its length straight on one side and notched on the other, of a lead carrier having means at one end for locking in difierent positions I in the barrel, and a rubber cone removably held in the opposite end of the carrier and adapted to clutch one end of the lead therein.

7. In a magazine pencil, the combination with a barrel, of a cylindrical tube or carrier fitted to and sliding in the barrel, a cone of soft elastic substance held in one end of the carrier and having lead inserted therein, and a spring thumb piece connected with the carrier whereby it is moved and locked in the barrel.

8. In a magazine pencil, the combination Withabarr'el, ofa carrierfitted to slide therein and a rubber cone fitted within the pencil and having one end of the lead inserted therein. In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses. I WALTER F. CUSHING.
