WILLIAM W. CASE, OF RAYMOND, CALIFORNIA.

PENCIL.

Application filed August 1, 1911. Serial No. 641,841.

Be it known that I, WILLIAM W. CASE, citizen of the United States, residing at- Raymond, in the county of Madera and State of California, have invented certain new and useful Improvements in Pencils, of which the following is a specification.

This invention relates, to pencils, and refers particularly to that class of such devices in which a hollow hand portion car-p ing means which is not dependent upon springs and the various other contrivances readily getting out of order, but to provlde a substantial mechanism having only a relat-ively small number of movable parts which are directly acted upon by the turning of a revoluble member carried at one end of the barrel.

This invention further aims to provide a pencil which is durable yet neat 1n design, one which may be easily and quickly operated, a pencil which occupies but small space and conforms to the general size and "shape of ordinary pencils, and a device which maybe economically produced.

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 side elevation of the improved pencil; Fig. 2 is a longitudinal central section taken through the same; Fig. 3 is a detail perspective view of the stem and its operating furrule; Fig. 4 is a detail perspective view of the-.tipof the pencil Fig. 5 is a detail perspective view of the split sleeve employed 1n attaching-an eraser; Fig. 6 is a transverse sectional view through the pencil; Fig. 7 is asideelevation of a slightly modified form of the pencil; Fig. 8 is a longitudinal central section taken through the same; Fig. 9 is'a side elevation partly in section of still another form of the invention Fig. 10 is a similar view of still another form of.the invention; Fig. 11 is a side elevation with parts in section of the form ofthe pencil as shown in Figs. 1 and Specification of Iietters Patent.

Corresponding and like parts are referred tom the following description and indicated in all the views of the drawing by'the same reference characters.

Referring to the drawing, 10 designates a barrel or handle forming the body portion of the pencil, the same preferably comprising an elongated metallic cylindrical memher open at its opposite ends. The lower end of the barrel 10 is provided with a tip' 11 in the form of a tapering hollow member being reduced at its upper end to provide a shank 12 engaging snugly in the lower end of the barrel 10. The tip 11. has a longitudinal central Opening 13 tapering toward the outer end of the tip and being of substantially elliptical cross section toward itsinner end. i

A hollow stem 14 is arranged centrally within the barrel 10 having its upper end secured to a disk 15 fixed in a ferrule 17. A plug 18 is secured in the upper end of the stem 14 to close the same. the stem 14 projects below the barrel 10 and into the tip 11, the lower end of the stem being s' lit at its opposite sides to provide a pair 0 spring jaws 19. Humps 20 are The lower end of formed in registration upon the outer faces of the jaws 19 and are adapted to normally lie within the receding sides of the opening 13 in the tip. The ferrule 17 is rotatably disposed over the upper end of the barrel 10 and is provided with a peripheral slot or groove ,21 adjacent to its lower edge for the reception of an outstandingrstud or pin 22- 'fixed upon thebarrel l0. he stud 22 not l only retains the ferrule 17 upon the barrel,

but it also admits of and limits the rotation of the ferrule to move but one quarter of its complete revolution. One end of the slot 21 opens into a notch extending. down therefrom and providing a. shoulder 23 against which the pin 22 strikes to hold the 1 05,

ferrule from turnlng when adjusted.- The opposite end of the slot 21 opens into an upwardly extending or--verticalslot24t0 receive the pin when it is desired to move the stem 14 down into the tip 11. L The upper end of the ferrule 17, above the disk 15, is reduced as at 25, and receives therein a peripheral slot 21 split sleeve 26 which projects slightly above the reduced portion 25 of the ferrule and carriesasuitable eraser 27 When the jaws 19 are-completely closed, as disclosed in Figs. 1 and 2, the lower ends of the jaws substantially register with the lower end of the tip 11 so as to bind a length of lead 28 between the jaws.

From the foregoing description, the operation is apparent 17 is moved up upon the barrel 10 the pin 22 moves into the slot 21. The ferrule can now be rotated through a quarter-turn to bring the shoulder 23 against the pin 22. When the ferrule 17 is in this position the jaws 19 are drawn up into the upper end of the tip 11' and into the enlarged part of the opening 13. The tip-11 is so positioned upon the barrel 10 that 'it is necessary to rotate the ferrule 17 through a quarter-turn to bring the humps 20 opposite the receding sides of the opening 13 and admit of the expansion or divergence of the spring jaws 19. When the jaws 19 are thus separated the length of lead 28 will fall by gravity through the stem 14 either out through the tip 11 or back into the stem, dependent upon the position in which the barrel 10 is held.

Referring to Figs. 7 and 8 of the drawing, disclosing a modified form of the inven-.

tion, the barrel 10 is turned in at its opposite ends for fixed engagement with the stem- 14 which is held rigid in the. barrel. The ferrule 17 closes the upper end of the barrel and tapers at its upper end to support the eraser 27. The lowerend of the barrel 10 is provided adjacent to its extremity with an annular shoulder 10 against which rests the upper end of the tip 11. The tip 11 is provided with an enlarged opening at its upper end rotatably receiving the lower end of the barrel 10. The tip 11 is provided with the having the shoulder 23' at one end and the vertical slot 24 opening into its opposite end. The barrel 10 carries,

below the shoulder 10, a pin or stud 22- engaging in the slots 21' and 24', as shown. The stem 14 extends below the barrel 10 and into the tip 11, and is split to provide a pair of spring jaws 19. The lower end of the tip 11 is provided, as in the preferred form with the tapering elliptical opening 13 adaplted to compress the jaws 19.

In al of the forms of the pencil the stem 14 is provided at its split or lead engaging end with inwardly disposed points or prongs 29 which are adapted to engage the opposite sides of the lead 28 and hold the same when the jaws 19 are brought-toward each other. The said jaws are also provided at their side edges with points or prongs 30 which are also inwardly disposed and are adapted to engage the side portions of the lead 28 at points behind the parts thereof engaged by the prongs 29. 1 I

j with relation to each other and In all of the forms of the invention the outer side of the stem 14 is spaced from the inner surface of the barrel 10 and in the compartment thus formed extra leads may be stored the drawings. In the forms of the invention as illustrated in Figs..1, 2, 9 and 11 the stem 14 is surrounded by a washer 31 which is located against the inner end of the tip 11 and is adapted to prevent the stored leads from entering the opening through the tip.

In the form of the invention as illustrated in Fig. lO-the barrel 10 is provided with a detachable cap 32 which is held in position on the said barrel by means of a slot and pin connection 33 of the usual pattern. The stem 14 passes through the center of the cap 32 and 1s provided at its outer end with a knob 34. The stem 14 may have lim ilt eld e cap 32 is provided at one side of the opening through which the stem 14 passes with. a recess 35, and lugs 36 and are carried by the stem 14. These lugs stand out from the stem 14 at approximately right angles to each other and the adjacent ends of the lugs are spaced fromv each other for a distance at least equal to the thickness of the central portion of the. cap. The lug 37 is provided at its inner end with laterally disposed shoulders 38. When the point of the lead 28 is projected beyond. he end of the tip 11 the In 36 lies in the recess 35 of the cap 32 as illustrated in Fig. 10 of the drawings. To retract the point of the lead within the tip llthe stem 14 is pulled back by grasping the knob 34 and the lug 36 slides through the recess 35 until the outer end of the lug 37 strikes the inner side of the cap 32. The stem 14 and knob 34 are then given a quarter turn so that-the end of the lug 37 is brought into register with the recess 35. The stem 14 is then given additional longitudinal movement in the barrel 10 which passes the lug 37 into the recess 35 until its shoulders 38 come in contact with the inner side of the cap 32. When this has been done the point of the lead 28 is retracted .well within the tip 11.

Having thus described the invention, what is claimed is:

' 1. A pencil comprising a barrel, a stem slidably mounted therein and having spring jaws. adapted to engage the lead, a cap mounted upon the barrel and through which the said stem passes, said cap having a recess at the side of the opening through which the stem passes, said stem having outwardly disposed lugs arranged in planes'at an angle having their inner ends spaced apart in a direction longitudinal of the stem.

2. A pencil comprising a barrel, a stem.

by the barrel and slidably receiving the stem, said cap having a recess at the side of its opening which receives the stem, outwardly disposed lugs carried by the stem and disposed in planes at an angle to each other andadapted to enter the said recess, the said lugs having their adjacent ends spaced from each other in a direction longitudinally of the 4 stem, the innermost lug being provided at its innermost end with laterally disposed 1e shoulders. v

In testimony whereof, I aiiix my signature in presence of two Witnesses.
