PENCIL.

Speciation of Letters Patent.

Patented May 9, l1911.

. Application 1ed April 14,1910. Serial No. 555,384.

To all whom it may concern:

Be it known that'I, CHARLES A. GAIsER,

acitizen o'f the United States, residing at Toledo, in the county of Lucas and State of Ohio, have invented certain new and useful Improvements in Pencils, of which the a' specification.

This invention comprehends certain new and useful improvements inpencilcases of the automatic clutch type, and the invention has for its object a simple, durable and efficient construction of device ofthis character in which the movable lead will be securely held and protected and by the use of which the end of the lead may be 'projected as desired, as the lead becomes worn in use.

NVith this and other objects in view, as will more fully appear' as the description proceeds, the invention consists in certain constructions, arrangements and combinations of the parts that I shall hereinafter fully describe and claim.

For a full understanding of the invention, reference is to be had to the following description and accompanying drawings, in which:

Figure 1 is a perspective view of one form of my invention; Fig. 2 is a longitudinal sectional view thereof; Fig. 3 is a transverse section on the line 3--3 of Fig. 2;

Fig. 4 is a similar view on the line 4.-4 of Fig. 2; Fig. 5 illustrates in perspective a lead, alead carrier and a portion of the combined carrier guide and rack; Fi 6 is a perspective view of another form o the carrier guide and rack; Figs. 7 8 and 9 are perspective views of different forms of leads that may be employed; Fig. 10 is a perspective view of that form of carrier which is used with the leadV illustrated in Fig. 9; Fig. 11 is a longitudinal sectional view of a modified form of the device; and,`Fig. 12

is a transverse sectional view showing another modified form.

Corresponding and like parts are referred to in the following description and indicated in all the views of the drawings by the same reference characters.

In that embodiment of my invention illustrated in Fig. 1, the numeral 1 designates the barrel of my improved lead holder, the same being formed of any desired substance lor material, such as wood, hard rubber,

like, or any 'combination Celluloid or the The barrel 1 is proof these substances.

vided with a longitudinal recess 2 which in the present instance extends throughout the length thereof and which is preferably of a depth extending slightly past the center of the barrel, and which is preferably of a'width substantially equal to the diameter of the lead which the barrel is intended lto contain. At the bottom of the recess 2,

the side walls thereof are longitudinally' grooved, as indicated at 3, and the bottoni wall of the recess is also preferably longitudinally grooved along its median line, as indicated at 4. 5 designates a combined carrier guide and rack which may be constructed ofsheet metal or otherwise, and which is of an extent slightly greater than the longitudinalrecess 2 in which it is designed to fit. The uide 5 is formed at its side edges with slightly undercut longitudinally extending anges 6 which t securely in the sidegrooves 3. The guide may be held in place as against longitudinal displacement, in any desired way. For instance, in that form of the invention now being described, the guide is formed at its rear end with a lug 7 engaging the end wall vof the bottom of the recess 2, and near its opposite end with nibs or protuberances 8 designed to abut against the front end of the barrel 1. As indicated above, the guide 5 serves as a rack, and to this end it is provided with a series of openin s 9 'which mayextend entirely therethroug the openings communicating with the bottom groove 4 of the recess 2, whereby thev tooth 10 of the latch 11 may 'secure a firm hold in the rack which is formed on the bottom of the guide 5 by the openings 9, the tooth extending through the openingsinto the bottom groove 4 in the locked position of the latch.

The latch 11 forms part of a lead carrier,

said carrier also including a body portion 12. In that embodiment of the invention now being described, the body portion 12 is formed of sheet metal bent along amiddle-longitudinal line so as to assume substantially a U-shape in cross section with substantially `parallel members, the edges of.

which are slightly turned out` as indicated at 13, so as'to slip along and be retained for a sliding movement by the flanges 6 of the carrier guide 5. The latch 11 is pivotally mounted intermediate .of its ends within thebody portion 12 and is formed at one end with a fin er knob or piece 14 whichprojeets outwardly through an open- Preferably, the tooth and the teeth` of the rack are so arranged that the latchy may be slipped forwardly inca direction to project the lead from the barrel 1. In the present instance, this is accomplished'by beveling the tooth 10, as clearly illustrated in the drawing. The body portion l2 of the carrier is formed at its forwardend .with a' preferably .integral hook 17 designed to engage. the lead,`\vhereby as the carrier 1s moved longitudinally, in the barrel, the lead may Tbe projected from the front end of-the latter or 'retracted into the same.

In connection with the improved lead holderwhich 'forms the `subject matter of the present invention, I have shown an improved construction of leadl which is the subject matter of another invention disclosed in va divisional application tiled on or about the 13th day of September, 1910, Serial No. 581,181.A In this divisionalA application, means are provided to prevent the breaking of the lead and for also rendering the `lead capable of being entirely used up and no Y portion thereof wasted. As one" means of 'securing this result, the lead which is designated 18, is wrapped with any suitable substance, such as a fibrous paper 19 of predetermined texture and thiclmess. Preferably,

I the tubular case ofsheathing thus formed, is

continued a predetermined distance. beyond the stub end of the lead and the extension of the tubular' sheathing of paper or the like preferably contains a plug '20 of wood or any other substance designed to be directly of` the carrier. In

engaged by the hook 17 order that it may be soengaged, a recess 2l is formed in the covered lead, said recess being cut through the casingV and into and the hook 17 being entered therein, as clearlyV illust-rated, in` the drawing. It will thus be manifest that the lead will be effec- -tually protected against breakage by falling or careless handlin the paper or the like being cemented to the lead and the covering because of its tubular shape, adding sulicient stiffness and strength to protect the lead against the ordinary causes of breakage.

As a modification 'of the lead protecting means and the leadv carrier or mover', 'reference is to be had to Figs. 9 and Y10, from the former of which it willbe noted that the sheathing, designated 19a, is extended past the stub endof the lead and crimped or compressed so as to form a projection 22. From Y Fig..10 it will be noted that the body portion 12 of the carrier is not provided with a hook,

such as 17, but in lieu thereof is formed with` clamping lingers .17 a designed to receive and mentioned hereinbefore.

the plug' barrel 1 in any desired Way. For instance,` I

the point protector may be formed with a `slight inward depression 25 designed to engage, with a depression 26 in the barrel, so that vwhen the protector is slipped over the forwardV end of the barrel and is in proper position, it may be given a sidewise turn so that the groove on the barrel 'may be caused to receive the depression of the protector, thereby securing the latter in place. j g It is to be understood that my invention is not limited to the precise construction and arrangement of parts of the barrel and slide ForA instance, as illustrated in AFi 11, the barrel may comprise a body portion 1a of wood, hard rubber, orany other substance ormaterial, carried by a Vtube 1'J of hard rubber or any other substance or material. In this form of the device, the tube is formed with a longitudinal slot 27 coinciding with the longitudinal slot 2a formed in the body portion 1. Both ends of the carrier guide, here designated 5, may be turned 4down over the ends of the body portion la, as indicated at 7?, whereby to hold the guide againstl longitudinal displacement. In this modification, the point protector, designated 23a, is held by frictional engagement between the tube- 1" and the body portion' 1? 0f the barrel, and the rear end of the tube 1b projects beyond the extremity of the body portion 1a so as to provide a holder for an eraser, or for a combined eraservand lead Sharpener, such as that covered by my companion application for `Letters Patent of the United States, Serial No. 555,385, filed april 14, 1910.

As a further modification of the barrel, reference is to be had to Fig. 12, which illustrates the barrel designated by l", formed of wood or rubber, with a relatively hard section 28 which is notched to form the rack for the lead carrier or mover. In this modification, a separate carrier guide is dispensed with, the out-turned edges of the body portion of the carrier being received in the side groove 3a of the longitudinal recess 2b which is formed in the barrel.

Various other modilcations in the construction, arrangement and proportions of the parts may be'made without departing .from the scope of the invention as defined in the appended claims.

` From the foregoing description in connection with the accompanying drawing, the

operation of my improved lead carrier will be apparent.
