Specification of Letters Patent.

Patented March 12, 1907.

Application filed February 'I, 1905. seal in. 244,582.

Be it known that I, FRANK M. AsHLEY, acitizen of the United States, and residing at 59 est One Hundred and Fifth street, New York city, New York, have invented certain new and useful Improvements in Penciltion.

This invention relates .to lead-pencils, and particularly to that type wherein a chuck is employed for clam ing a "removable lead, and a compartment in the body of the pencil provides for carr 'ng a suppl of such leads.

A prominent ob j ect of the invention is the production of a pencil of the character 'de scribed which will be exceedingly simple and cheap in construction, ca able of high efliciency, and'in which the cliuck maybe quickly inserted in position to insure the retention of both the same and the lead with a high degree of positiveness, and which chuck may with equalfacility be removed, carry ing with it said lead. The chuck is so conditioned that the lead will be grip ed both at siderable distance to the rear ofv said extremity, thereby obviating tendenc of breakage of the lead due to lateral play the same adjacent to its point and insuring somewhat-extended gripping-surfaces, so that the slipping of the lead in the chuck will be prevented.

A further object of the invention is to make the mutuallyengaging .portions of both the pencil-bodies, or, as they may be termed, the .holders, and the chucks, the latter with different capacities, all of the same size, whereby thechucks can be interleads may extend entirely through the chucking portion of the pencil when a long lead is employed; but in all cases when the chuck is removed from the holder the lead is removed with it.

There are other important features connected with the invention, which, besides those referred to, are already set forth in the 1 subsequent detailed description and illus-i trated in the accompanymg drawing, in which latter j Figure 1 indicates a pencil the body of which is shownincentra longitudinal section, and the chuck and lead are shown by exterior views. Fig. 2 is an end view of Fig. 1. Fig.. 3' is a central sectional view of a modification of the pencil and chuck, the latter being shown as holding a short lead pointed at each end and the body indicated as being made of-metal. Fig. 4 is an end view of Fig. 3 as it would appear if Fig. 3 were not in section. Fig. 5 is a view, partly in section, which shows a modification of the form of the chuck. Fig. 6 is an end View of the same. Fig. 7 is a view, partly in section, which illustrates a modification wherein, the chuck is screwed in the ody of the pencil instead of being held therein by friction. Fig.

i 8 is an-enlarged sectional view of a modification of the form of the chuck. Fig. 9 is an end view of the same. larged exterior view of the pencilillustrated in Fig. 1.

In-the drawings, A indicates the body of the pencil, B the chuck, and C the lead-pencil. The body A may bemade of wood, which may be "neatly enameled in various colors or may be made of enameled tin or other metal or hard rubber.

In Fig. 11 have illustrated the body as being made from wood or hard rubber and in Fig. 3 as being made from drawn metal. The body is provided at the chuck end with a taper portion A, of the chuck B fits and is secured to the body A by friction. In Fig. 1 the chuck is provided with a central cylindrical opening throughout its entire length, into which the lead 0 fits in sliding relation. One side of the chuck is provided with -a longitudinal slot B, which extends throughout its entire length from its exterior surface to the opening in which the lead iits', and when the chuck containin portion A of the body the chuck, due to its elasticity, binds the lead, and thereby holds both chuck and the lead firmly in the body A.

.The chuck Bis provided with an enlarged diameter B", which serves-as an abutment for the fingers to use in removing the chuck B from the body A of the pencil. On, the opposite side of the chuck B from the slot B is a slot B, which extends parallel to the circular opening in which the lead fits and serves toallow of the chuck being easily compressed on the lead C when inserted in Fig. is an eninto which the shank end,

the lead is forced into the taperv the tapered portion A of the body. Where the: chuck is made very small in diameter and of soft wood, the slot- B may be dispensed with but where the chucks are made of fairly large diameter the slot B is essential to its successful operation- Referring to Fig.; 3, thelead o ismade.

short, and the Opposite ends are both pointed, and in this case thelead is made of larger diameter than the opening which extends throughout the length of the chuck; but the opening s'ervesthe purposeof allowing a pin to be inserted from the opposite end .of the chuck to that in which the lead C." is held,

whereby in case of the breaking of thelead C in such a manner asto leave a portion of frespects the chuck B is made in a similar the'lead Within the jaws of the chuck the said. broken part may be forcedfrom the chuck by a pin being inserted behind it,

springof the chuck will be equal on both sides of the same-and will firmly hold the lead 0 when inserted in position in the taper portion A.

Referring toFig. 5, it will be noticed that the taper portion A is decreased in diameter at A and beginning at this point the chuck B" is made with two fiat sides parallel with each other, as shown in Fig. 6. Inother manner to that. just described with reference to Fig'. 3.

In Fig. 7 the chuck B8 is provided with a' tapered shank which is provided with a thread B which engages with a similar thread in the-body of the holder A The chuck B isvcompressed and holds the lead when the same is,screwed as far into the.

holder A as it will go, which will be clear to any one skilled in the artto which this invention pertains. In some cases the leads used in these pencils are not found to beof equal diameters, and when the chucks are made of any considerable length the friction between a long lead and the opening into which it fits in the chuck is such that there is sometimes a difliculty in removing the lead through the chuck. I have overcome this difliculty to a considerable extent by enlarg; ing the diameter of the opening in the shan end of the chuck, as illustrated at C in Fig.

7 and C in Fi 8, in which last-named figure the chuck is s own considerably enlarged.

In Fig. 8 Ialso illustrate an abutment B, being cut away on each side of the main body of the chuck -B as illustrated in Fig. 9 This form allows the chuck to be more easily vschools andofiices.

held andaiiords a firmer grip to the fingers when the chuck is held by excessive friction in the taper portion of the'holder-body.

- It is obvious that .when carried in. the pocket the chuck may be released from its friction in the tapered portion of the holderbackward in the chuck andthe chuck itself again quickly held in said tapered portion, wnereby' when carried in the pocket the point of the pencil will-be protected from breaking. In the case of the short leads body, and thepencil-point maybe forced shown in Figs. 3 and 5 this advantage is not,

- sought, for the reason that.when leadsof this form are used they are so short andeasy to handle thatit wouldinvolve but a moment to remove the same from the chuck and drop them within the body of the pencil,-- which constitutes a receptacle A" for carrying a sup- -plyof the leads to be used.

' The extreme cheapness at which these pencils may be made, the firmness with which the leads are held in'the pencil when in use, due to the extreme bearing-surfaceupon the leads 'ail'orded by the construction of the chuck, and the neatness and general utility of the design is such as to make this" form of pencil particularly suitable for use in public Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is'

1. A twopart pencil embodying a holder and a chuck, the former integrally closed at its butt and contai a lead-compartment merging in an exten ed inwardly-tapering hearing at the-holder front, and the chuck the tapering bearing of the holder continu- 'ously throughout the length of said bearing.

2. A two-part pencil embodying a holder and a chuck, the. former integrally close'dat f its butt and containin a lead-compartment merging in. an exten ed inwardl ta erin' hearing .at the holder front, and he dhucl; containing an extended longitudinal leadpassage contractedat' the forward extremity of the chuck to contribute in forming a gripping portion thereat, the rear major part of having a lead-gripping ortion at its forward extremity and provide with an extended tapering shank adapted tobe-engaged within" the passage being of larger diameter than the assa e at the said' i i ortion said huck being also provi de d Hg p rear shank adapted to be engaged within the tapering bearing of the holder continuously throu bout the ength of said bearing.

3. two-part pencil embodying a holder and a chuck, the former integrally closed at its butt-end and containing a lead-compartment; merging in an extended inwardly-tapering hearing at the holder front, and the chuck having an extended rearwardly-taper mgsh'ank ada ted to conform within said -bear1ng, said 0 uck containing a central lonwith an extended extended rearwardly-tapering shank, the latter adapted for engagement Within the holder-bearing continuously throughout the length of the latter, and the enlargement bein removed at opposite sides to render said .en argement convenient for the engagement of the fingers in the removal of the chuck, said chuck containing a central longitudinal lead-passage, and an extended radial slot opening through the chuck side and intersecting said passage, the chuck having a gripping portion at its front extremity from which latter the passage and the slot rear- Wardly extend. g

5. A two-part pencil embodying a holder and a chuck, the former integrally closed at.

its butt-end and containing a lead-compartment merging in an extended inwardly-ta pering bearing at the holder front, and the chuck having an intermediately-located external enlargement, and an extended rearwardly-tapering shank, the latter ada ted for frictionally conforming within said earing radial slot opening throughout its entire length, and the enl argement being removed at opposite sides to render said enlargement convenient for the engagement for the fin ers in the removal of the chuck, said chuck containing a central longitudinal lead-passage and an extended through the chuck side and intersecting said passage, the-chuck having a gripping portion at its frontextremity from which latter the passage and the slot rearwardly extend.

6. A two-.part pencil embodying a holder and a chuck, the former containing a leadcompartment merging in an extended inwardly-ta ering hearing at the holder front, said chuc having an extended rearwardlytapering shank adapted to conform within said bearing, and provided with a central longitudinal lead-passage and an extended radial slot opening through the chuck side and intersecting said passage, and provided with an enlarged portion to serve as a grippingsurface, the rear part of the pencil-passage being of larger here than the front part so that the pencil will he held exclusively by the front end of the'chuck.
