UNITED STATES FRANK J. VIERLING, OF MINNEAPOLIS, MINNESOTA.

PENCIL.

Application filed June 14, 1922.

To all whom it may concern Be it known that I, FRANK J VIERLING, a citizen of the United States, residing at Minneapolis, in the county of Hennepin and State of Minnesota, have invented certain new and useful Improvements in Pencils, of which the following is a specification.

My invention relates'to improvements in pencils, designed particularly for holding crayons, and has for its object particularly to provide means whereby the crayons or leads are most conveniently stored within the magazine of the pencil and are efliciently held in position for use and easily removed from the holding means.

To this end the invention consists in the construction, combination and arrangement of parts hereinafter more particularly described and claimed.

In the accompanying drawings forming part of this application Figure 1, is a central longitudinal section of my improved pencil.

Fig. 2, is an elevation of the inner member of the pencil, with the members thereof shown in separated position.

Fig. 3, is a cross section on line 3-3 of Fig. 1.

Fig. 4:, is a fragmentary longitudinal section through the friction engaging'port-ion of the pencil members, and

Fig. 5, is a sectional view of the inner end of the inner pencil member.

A and B indicate, respectively, inner and outer casings telescopically arranged with freedom for compound axial and rotary movements in respect to each other. The outer casing B has acontracted or pointed end 2, through the open nose of which the lead or crayon may be fed or retracted as hereinafter pointed out. The outer casing B is formed with an open outer end to allow the insertion of the inner casing A. Frictional engagement between the inner and outer casings is achieved as by the expanding of the wall of the inner casing along the longitudinal slot 4: formed in the inner. casing intermediate of its ends. Removably and telescopically fitted in the inner end of the casing A is a cap portion 5 formed with a surrounding head 6 to abut against the end of the casing A and form a stop. Loosely supported in the exposed end of the cap 5 is a lead or crayon holding device con sisting of a tube 7 projecting outwardly from the center of the washer 8, said washer Serial No. 568,136.

being supported preferably in a loose manner within the beaded end 9 of the cap to permit a wobbly support for the crayon 10, and protect it against breaking as it is fed by the movement of the casing B.

The forward end 11 of the tube 7 is rear wardly tapered as shownin Figure 1, to form a friction grip for the crayon and, as shown, the tube opens through the washer for the purpose hereinafter set forth.

In use, by holding the outer casing B and turning the inner casing A, by taking hold of its outer end, the inner casing may be rotated and pushed forward to feed the lead or crayon through the point 2, the frictional engagement between the two casings holding the inner casing wherever set, and the wobbly support for the lead holding means protecting the lead or crayon. against breaking in the adjustment of the pencil memers.

The construction of the inner end of the inner casing A is of particular importance, in that it not only allows the lead to be placed within the casing, through a concealed and protected opening, but ermits the removal of the crayon or lead after use, to be pushed out of the holding tube by removing the cap from the casing A by projecting a toothpick or equivalent device through the tube from inside the cap to free the tube.

The tapered construction of the lead holding tube and the wobbly connection of said parts, act to hold the lead in a firm manner and at the same time protect it against being broken by any slight lateral movement of the inner end of the casing A, with respect to the outer casing.

I claim 1. A pencil of the class described, comprising inner and outer telescopically connected casings, the former of which has a removable inner end and an open ended rigid lead holding tube open at both ends and connected by said inner end, the outer of which casings has a contracted end with an opening in alinement with the lead-holding end of said inner-casing.

2. A pencil of the class described, comprising inner and outer telescopically connected hollow casings, the latter of which has a contracted end formed with a central opening, a tubular end member removably disposed in the inner end of the inner casing, and a lead holding member loosely has a contracted end formed With a central opening and the former of Which has a removable tubular inner' end, a leach-holding tube inwardly tapered atits outer end for lea'd -holding purposes; and having a washer like" inner end movably supported in and closing-{the outer end of the remoi' able end of the inner casing for" the purpose set -tort-h.

4. A pencil comprising inner and outer basing-stelescopicall elated and both beingihollo'iv, a tubular closure cap for the for- Ward end of the inner casing, open; at both ends and having: its for-ward e'iid formed into asocket, and a lead holding element having apart fittin-gin the socket for Wobbling movement and for closing the tubular cap.

5. A pencil comprising a hollow casing, a removable tubular closure cap for one end, a tubular lead-holding member secured in the cap and open at bothfl en'd'swhereby a lead may be ejected tromt-he member by" inserting a wire through the opposite" end of the men'ib'er, and at protecting casing" inclosing the member and Cap} A In testimony Whereo't I affix my signature.

FRANK J. VTERLING.
