MAGAZINE-PENCIL Specification of Letters Patent.

Patented 0c't.12, 1915.

Application filed December 31, 1914. Serial No. 879,820.

This invention relates to certain new and useful improvements in magazine pencils, and the primary object thereof is to provide a pencil. which has means for holding a plurality of points that are adapted to be used one at a time, the points being removed from the container, and applied in position for use, as desired.

Referring to the drawings: Figure 1 1s a side-elevation of the invention; Fig. 2 is a longitudinal sectional View partly in side elevation; Fig. 3 is a similar view completely in section; and Fig. 4 is a side elevation of a modified form of the invention.

Referring more particularly to the drawings, the reference numeral 1 designates the casing of the pencil, interiorly threaded at its outer end 3 and provided with a cap 2 that serves to close the said end 3 of the casing 1. Adjacent the other end of the casing 1 is provided a partition 4 which serves as one of the walls of a chamber or compartment 5 that contains the points 30 of lead. The casing 1 is provided adjacent the partition 4 with an annular bead 6, being reduced in diameter at 7, so that same is of less diameter than the body portion of the casing 1. Rigidly secured to the reduced portion 7 of the casing 1 and projecting out therefrom is a pin 8, the purposeof which will be hereinafter described. A tubular member or sleeve 10 is received within the reduced portion 7 of the casing l, and is provided with an annular intermediate shoulder 11 which limits its inward movement Within the "casing 1 by engagement with the end of the reduced portion 7. The tubular member 10 is tapered forwardly at 12, and is of truncated form having a free end 13. Slidable within the tapered portion 12 of the tubular member 10 is a tapered block 15, which is pressed forwardly by means of a coil spring 16, one end 17 of the latter engaging the rear end of block 15 While the opposite end abuts the partition 4. Surrounding the reduced portion 7 of the casing 1 is a sleeve 20 having the end 21 abutting bead 6 and provided with a bayonet slot 22 that receives the pin 8 for the purpose of holding the sleeve 20in place on the casing 1. The forward portion of the sleeve 20 is tapered at 25 and extends beyond the free end ofthe tapered portion 12 of the tubular member 10.

As shown in Figs. 2 and 3, the lead is in the form of conical or tapered bodies 30, the

greatest diameter of which is in excess of the diameter of the free or smallest end of the sleeve 20. In use, one of the lead points 30 is inserted in the reduced tapered portion 25 and is held in-its forward position by means of the coil spring 16 which forces the block 15 forwardly against the flat base end of the lead point 30. When it is desired to renew the point 30 for any cause, the sleeve 20-is turned and slid forwardly until the bayonet slot is disengaged from the pin 8, whereupon the sleeve 20 is removed and the block 15 is caused to project from the tapered portion 12 of the sleeve 10 by the action of the spring. One of the points is then removed from the magazine 5 and placed in the sleeve 20 following which the sleeve 20 is placed over the tapered portion 12 of the sleeve 10. The spring 16 is again placed under tension by reason of the lead engaging the block 15, thus always keeping the lead in an advanced or forward position. After the sleeve 20 is placed in position over the reduced portion 7 of the casing 1, the bayonet slot 22 is again engaged with the pin 8,'thus holdingthe partsr'in their assembled position.

In the modified form shown in Fig. 4 in lieu of having one of the ends of the casng closed by the screw cap 2,the casing is provided withan elongated slot or opening 40, over which is fitted a cap 41 provided with an elongated slot or opening 42 for registry with slot 40. In this modified form of the invention when it is desired'to remove a piece of lead from the container or recepta-- cle 5, the cap 41 is turned until its slot 42 is brought into register with the slot 40in the casing 1, whereupon one of the points may i partition in the casing, a tapering tubular member within the reduced portion of the casing, a tapered block conforming to said tubular member, a coiled spring having one end bearing against said partition and its oppositeend engaging said block to force the latter forward, a sleeve for carrying the lead points surrounding the reduced portion of the casing, said block engaging the lead to force the latter forwardly, and means for securing the sleeve to the casing.

' 2. A magazine pencil comprising a casing,

, a tapering sleeve removably sec'ured to one end of the'casing, a writing point carried by said sleeve, a second sleeve carried by the casing and'lying within the first named sleeve, a block slidably mounted in the second sleeve and engaging'the writing point,-

- and means for maintaining said block in engagement with the writing point.

-3. A magazine pencil comprising a casing, .7 a'tapering-sleeve carried thereby, a writing point 'mounted in the sleeve, a second sleeve carried by the casing and lying within the I and spring means for maintaining said block first mentioned sleeve, a block carried by the secondsleeve, and engaging the writing 'pointto maintain same in operative position,

in engagement with the writing point.

4. A magazine pencil comprising a casing having a reduced portion on one end thereof, a sleeve having a portion thereof formed to engage the reduced portion of the casing and having a tapering portion, a writing point carried by the tapering portion, a second tapering sleeve within the first mentioned sleeve, a partition in the-casing, a tapering block slidable in the second sleeve and engaging the writing point, and means engaging the partition and the tapering block to secure the writing point in position.

5. A magazine pencil comprising a casing, a tapering sleeve carried by one end thereof, a writing point in the tapering sleeve, a second tapering sleeve lying within the first named sleeve and carried by the casing, a tapering block carried by the second sleeve and engaging the writing point, a partition in the casing, and a coil spring having one end engaging the said sliding block and its opposite end engaging said partition to hold the writing point in position.

In testimony whereof, I affiX my signature in presence of two subscribing witnesses.
