JOHN A.. HOLILENBBGER, oF'HAGEnsTowN, MARYLAND.

Application led November 11, 1914. Serial No. 871,592.

To vall whom t may concern.

Be it known that I, JOHN A. HOILEN- BERGER, acitizen of theUnited States, residing at Hagerstowm- 1'in the county of Washington and State of Maryland, have invented certain new and useful Improvements in Magazine-Pencils; and I'do'hereby declare the Ifollowing to b`e`aI full, clear, andexact description of the invention, such las will enable others skilled in' the art to which-it Aappertainsto'nike and. use the same, reference being had to the accompany-ry ing drawings, and to tliejletters and figures of reference marked thereon, which form a part of this specification.

This invention relates to new and useful improvements in magazine pencils and the object in view is to produce a simple and eiiicient device of this nature having a magazine adjacent to the forward end of the barrel and in the provision of a plunger means actuated by the rotation of a shell to cause the lead` to be'fed forward.

My invention comprises various details of s construction, combinations and" arrangements of parts which will be hereinafterl fully described, shown in the accompanying drawings and then specifically defined in the appended claims.

I illustrate my invention in the .accompanying drawings, in which:

Figure 1 is a central vertical sectional view through the pencil made in accordance with my invention. Fig. 2 is a sectional view on line 2--2 of Fig. 1,.and Fig. 3 is a sectional view on line 3- 3 of Fig. 1.

VReference now being had to the details of the drawings by letter, A designates a shell having an integral tubular portion B projecting therefrom at one end and adapt-l ed to receive the lead B when placed there- 1n. A filler C is mounted in the tapering portion of said shell and forms an end wall 'of a magazine adapted to receive a plurality of leads. N positioned about the central tubular portion, as shown clearly in Fig. 2 of the drawings. A-cylindricalbarrel portion D telescopes over the shell A l and receives a hollow cylindrical member E telescopin within its other end and which member 1s provided with an elongated grooveE, and F designates a cylindrical shell which telescopes over a contracted portion of the member E and is rotatable thereon, a portion H of the shell F being conf stricted to hold the same from'pulling olf j Specification of :Letters Patent.

' the end of the .,member. AA plunger,'desig' nated by letter'O, is mounted within the holi low portion of the member E and also within the tubular portion B and servesas a means for pushing the lead forward.

The means forv moving the plunger consists of a laterally projecting portion O at the end thereof which engages the -groove E to prevent the plunger from rotating when being moved back and forth, while said: lateralfprojection O also engages between the coils of the member K, serving as a thread and affording means whereby the coil K, which is fastened to the filler I-I which is secured to and rotates with the cylinder F, will cause the plunger to be fed B and the parts assembled as shown 1n Fig.'

1,:the magazine holding a supply of leads to be inserted -whenever desired within the tubular portion. B'y the rotation of the shell F, the coil K will rotate therewith and, by reason ofthe lateral projection O extending'through the 'coil K, the latter will act as a screw and cause the plunger to be driven forward or backward' accordingly as` the shell F is moved and rotated in one direc- .tion or the other, thus affording means for driving /the plungerv against the inner end of the lead to feed the same forward. or,

on the reverse movement of said shell F, to 'cause the plunger to be retracted. v

What I claim to be new is 1. A magazine pencil, consisting of a shell with a contracted portion and a central tubular lead receiving portion, a' cylindrical, barrel portion telescoping over a contracted part of said shell and extending beyond .the inner end thereof, a cyllndrlcal casing-within said barrel portion and provlded with a longitudinal opening in alinement with the lead receiving tube and provided with an elongated groove in the wall of sald opening? @shell telescoping over and. rotatableA y about said casing, a spring fastened to said rotatable shell, a plunger mounted in said tion of the latter limiting the movement lof the plunger in one direction.

2. A magazine pencil consisting of a shell with a contracted portion and a .cenbtral'tubular lead receiving portion, a cylindrical barrel portion telescoping overa contracted partof saidshell and extending beyond the 1nner .end .tbereof, 'a cylindrical casing .Within said barrel portion and provided `-Witli a longitilfdinal opening in aglinement ,with `the .lead receiving tube' and provided with en velongated. groove inthe avallfof said open# Mamet ing,` a shell teleseoping over and rotatable about said casing, a spring fastened to said.
