w. J. FRINK MAGAZINE PENCIL Filed Jan. 11. 1921 Patented Dec. 30, 1924.
UNITED STATES WA TER J. FRINK, or CHATTANOOGA, TENNESSEE.
MAGAZINE PENCIL.
Application filed January 11, 1921. Serial No. 436,446.
To all whom it may concern:
Be it known that I, WALTER J. FRINK, a citizen of the United States, residing at Chattanooga, in the county of Hamilton and new and useful Improvements in Magazine Pencils, of which the followingis a specification.
My invention relates to magazine pencils,
wherein a plurality of independent leads are carried Within the shell of the pencil in a suitable receptacle, whereby they may be used to replenish the pencil when desired, suitable mechanism being employed to feed the independent leads from the pencil as used. The object of the invention is to provide a pencil of this kind, which is simple in the extreme, consisting of comparatively few parts, which may be easily assembled and held together without the aid of fastening any of the parts permanently together, by solder, rivets, screw-threads, or the lik e.
A further object is to so arrange the parts that they may be readily disassembled for repair or adjustment or cleaning.
In the accompanying drawings:
Fig. 1 is a longitudinal sectional View of the complete pencil;
Fig. 2 is a detail View of the tubular guide member;
Fig. 3 is an enlarged transverse section on line 3-3 of Fig. 1;
Fig. 4 is a detail sectional view of the forward end of the pencil, showing a modified form of the tubular guide.
Fig. 5 is a detached perspective of a portion of the guide tube showing a modified form of holding means.
The numeral 1 indicates the outer hollow shell or barrel made of any suitable material, being preferably drawn out or tapered at one end to form a conical tip 2. The extreme forward end of the tip is slotted as at 3, 3, to form jaws 4, 4, adapted to firmly the lead 5.
rranged concentric with the outer shell 1 is an inner cylindrical guide member 6, extending substantially the full length of the outer member, the forward end thereof being received and supported by the tapered end of the outer shell. This guide member preferably is provided with a longitudinal slot 7 extending the full length thereof, the longitudinaledges or flanges 8 and 9 of the said guide member adapted to State of Tennessee, have invented certainxo flare outwardly, and bear against the inner wall of the outer shell.
' 10, indicates a' flange arranged at the outer end of the guide 6',adapted to extend in the opposite direction to the flarededges 8 and 9, and to act to properly align the guide 5.
To hold the guide member (5 against longitudinal movement, I preferably provide an inturned head 11 at the outer end of the shell 1, which acts as an abutment for the flange 10 and the notches 12 in the flanges 8 and 9. It will be observed that the tubular member is nowhere permanently secured within the shell, and may be readily removed at any time for adjustment or clean- :i ng the shell of small particles of lead which may be wedged Within, thereby preventing the proper manipulation of, the pencil.
The lead-actuating mechanism preferably consists of a tube or sleeve 13, adapted to fit snugly within the guide members 6, the former being provided with a helical slot 14. Received within the tube 13 is a plunger 15 formed of a piece of wire having an offset portion 16 passing through the helical slot 14, and extending longitudinally along the tube 13, being received in the longitudinal slot 7 of the guide 6, thereby holding the plunger against rotation with respect to the guide member and the outer casing, yet permitting longitudinal movement of the plunger by the rotation of the slotted sleeve 13. The outer end of the tube 13'is squared as at 17, and is received within a similar opening 18 in the ferrule or cap 19, which is received over the outer end of the shell 1, and held against longitudinal movement by the depression 20, which registers with the depressed bead 11. The rotation of the ferrule 19 imparts a rotary motion to the tube 13, which causes the plunger 15 (which is held against rotation by the slotin the tube) to be fed along the tube, the inner end thereof coming in contact with the lead 5. causing it to be fed outwardly from the shell.
21, indicates an annular space between the outer casing and the inner guide tube 6, which forms a magazine for extra leads 22. This space is adapted to accommodate a sufficient number of leads to render comparatively long use of the pencil on one charge.
In Fig. 4 I have shown a modified form wherein the guide tube 6 has a restricted inner end 23, of such a construction as to grip the inner end of the lead 5, thereby greatly stiffening the general support of the lead 5 1. A magazine pencil comprising an outer-- shell having a conical tip, an inner removable longitudinally slotted guide tube received centrally of the shell, one end being received Within the conical end of the shell, the other end of said tube being provided with a radial flange adapted to engage the inner Wall of the outer shell to friction-ally hold the tube in place, a lead received in the conical tip, a helically slotted sleeve received in said guide tube adapted to surround the inner end of the lead, a plunger arranged .within said helically slotted sleeve having a portion thereof offset, passing through the helical slot and being received within the longitudinal slot of the guide-tube, whereby it is held against rotary movement, and a cap carried by the outer end of the outer shell and in engagement with the helical slotted sleeve, whereby the latter is rotated to elfecta longitudinal movement of the plunger. v
2. A magazine pencil comprising a shell having a conical tip','and a longitudinally slotted and flanged guide tube received centrally of the shell, of such a diameter as to elfect an annular space between said guide tube and shell, one end of said guide tube bemg received in the conical tip, and the longitudinal flange formed at one side of said slot and adapted to bear against the in-v supporting said tube in said shell a lead received in said conical tip, and lead actuatin means recelved in said guide tube and held against rotation by the longitudinal guide tube slot.
3; A magazine pencil comprising a shell having a conical tip, and a longitudinally slotted and flanged guide tube received centrally of the shell, of such a diameter as to effect an annular space between said guide tube and shell, one end of said guide tube being received in the conical tip and the longitu inal flange formed atone side of said slot and adapted to bear against the inner wall of said shell, resilient means projectin from the other side of said tube from sai flange adapted to bear against said shell and ,to cooperate with said flange for centering and supporting said tube in said shell, a bead on said shell with which said resilient means co-operates for frictionally and re-' movably holding said tube in sald shell, a lead received in said conical tip, and leadactuating means received .in said ide-tube and held against rotation by the ongitudinal guide tube slot.
. In testimony whereof I aflix my signature.
