CHARLES A. STICKNEY, OF ST. PAUL, MINNESOTA.

PENCIL.

Specification of Letters Patent.

Patented Aug. 8, 11922.

Applicationfiled July 26, 1920 Serial No. 399,171.

To all whom it may concern Be itknown that I, CHARLES A. STICK- NEY, a citizen of the United States, and a resident of St. Paul, in the county of Ramsey and State of Minnesota, have invented certain new and useful Improvements in Pencils, of which the following is a spec]- fication. One object of my invention is to provide in a pencil improved means of feeding the lead.

Another object is to provide an improved formof magazine for extra leads.

.part of this specification.

In the drawing, Figure ljis a longitudinal section of my improved pencil; Figure 2 is an enlarged section taken on the line 2-2,

Figure 1; Figure 3 is a detail of the screw Figure 4 isan end view of the same; Figure 5 is a detailof the pin; Figure 6 is a detail of the tip; and Figure? is a section taken on p the line 7'7, Figure 1.

As shown in Figure 1 the stem 1 is drilled but at difi'erent diameters and threadedat 2 35- to receive the feedscrew 3.v

Stem l is also threaded at 4 to receive the threaded portion of the tip 5 The tip 5 is screwed tightly intothe stem 1, which is preferably made of rubber, and is broached outat 6, as shown in Figure 2. so the lead '7 will be friotionally held in the stem. I

The screw 3 has insertedtherein the pin 8, and the other end of the screw has a squared head 9 thereon. -The crown 10ihas.

an inwardly extending barrel 11, fitting the interior of the stem snugly at 12, but having two flutes 13 and 14 running longitudinally .thereof to serve as a magazine, and the re-.

tainer 15 holds the leads carried therein in place as the crown is withdrawn to obtain a fresh lead. This crown is squared out from the shoulder 17 to the head end to receive the squared head 9' of the screw 3.

' The spring 16 is positioned between the shoulder 17 of the crown and the squared head 9 of the screw to retain the crown in its normal position.

It will be evident that with the lead 7 in the position as shown the rotation of the crown 10 will turn the screw 3 in the threads of the stem at 2, thereby forcing out the lead 7 to the desired length.

An eraser 18 may be held in the crown 10 as shown.

- The style of pencil shown and described is of neat appearance, economical to manufacture, and provides with the stem and feeding mechanism a suitable magazine, so the purchaser of a pencil receives not only the lead in the stem, but also an additional su l ile I have described my invention and illustrated it in one particular design, I do not wish it understood that I limit myself to this construction, as it is evident that the application of the invention may be varied in many ways within'the scope of the following claims.

Claims:

1. In a pencil the combination ofa stem having an axially positioned interiorly threaded portion, a feed screw cooperating with said threaded portion and havin a squaredhead, a crown having an inwar 1y extending barrel with a squared aperture running; longitudinally of said barrel in which said squared head may play, and resilient means positioned between said squared head and the inward end of said barrel.

2. In a pencil the combination of a stem having an aperture extending longitudinally therethrough of difierent diameters at different portions of said stem, said aperture havin at one portion thereof an interior thread: a crown having an extended barrel positioned in the aperture at one end of said stem and rotatable therein, said crown having an aperture extending therethrough, an interior shoulder at one end of said aperture, a feed screw positioned in said crown and having a squared head slidable in a squared portion of the aperture of said barrel, and a spring positioned between said squared head and said interior shoulder of said barrel.

' 3. In a pencilthe combination of a stem having an aperture extendin longitudinally therethrough of different diameters at different portions of said stern, said aperture havin at one portion thereof an interior threa a crown having an extended barrel positioned in the aperture at one end of said stem and rotatable therein, said crown having an aperture extending therethrough, an interior shoulder at one. end of said aperture, a feed screw positioned in said crown and having a squared head slidable in a squared portion of the aperture of said barrel, a spring positioned between said squared 10 head and said'interior shoulder of saidbar-' rel, a tip carried by the opposite end of said barrel and having a longitudinal aperture therethrough, with means for gripping a from said barrel as said crown is rotated.--

CHARLES -A. STIOKNEY.
