PENCIL.

Specification of Letters Patent.

Patented Nov. 1'7, 1908.

Application filed February 6, 1908. Serial No. 414,545.

To all whom it"may concern:

Be it known that I, JonN D. R; LAMsoN,

a citizen of the United States of America, residing at Toledo, 1n the county of Lucas and btate of Ohio, have invented certain new and useful Improvements 1n Pencils,

of which the following is a specification,

reference being had therein to the accompanying drawings.

This invention relates to improvements in pencils for holding detachable lead crayons and more especially to that class of pencils shown and described in my Letters Patent of the United States, one dated November 22, 1904 and numbered 775, 19?) and one dated May 21, 1907 and numbered 853,983.

The object of this invention is to provide a pencil of the class described, with cheap and eflicient means for holding, projecting and retracting the crayon and also with certain other new and useful features in the construction, arrangement and combination of parts, all as hereinafter more fully described-and particularly pointed out in the claims, reference being had to the accompanying drawing in which Figure l is an enlarged axial longitudinal section of a device embodying the invention; Fig. 2, a further enlarged transverse section on the line oa-w ofFig, 1; Fig. 3, a similar section on the line yy; Fig. 4,a section on the line z2; and Fig. 5 is a longitudinal section similar to that of F ig. 1, showing a crayon in place and lllustratlng the manner of operating the crayon slide.

As shown in the drawing, a sheet of metal.

is rolled to form' the cylindrical body or barrel 1' of the pencil having a longitudinal slot in one side, the edges of the slot being inturned along the slot. The edge 2 at one side of the slot is notchedtoform a series I of teeth 3 and the metal at the other side of the slot forms an inwardly extending wall 4 and at the axis of the body isrolled into a tube 5 with a slot adjacent to the the tube and extends outward, through the slot in the body. This slide is preferably a sheet metal stamping formed with an upper longitudinallyextendingspring-arm9having a lug 10 near its free end projecting outward through the slot in the body of the pencil, and also formed with a lug 11 formed by bending the end of the arm laterally. A lower spring-arm 12 is adapted to engage and slide within the crayon tube and the free end of this arm is formed with a longitudinally extendin hook 13, the inclined end of which hook is above the plane of the lower edge of said arm 12 and at the base of the hook is a'shoulder 14 so that when the crayon 15 is forced into the crayon tube through the conical end, the inner end of the crayon will be forcedbeneath hook and abut against the shoulder. The hook isformed with a sharp point so that when the.

crayon is forced beneath said point it will indent the crayon sufficiently to firmly hold it from becoming detached and dropping out. If desired, a notch ma be provided in the crayon for the point 0 the hook to engage.

In writing, a pressure is applied to the outer end of the crayonwhich tends to force said crayon back into the tube. This end thrust is taken by the shoulder 14 which the inner end of the crayon engages and the slide is prevented from being forced rearwardly by the engagement of its lug 11 with the teeth 3 on the body, these teeth being formed with a straight side to engage the lug and prevent rearward moving of the slide and with an inclined side to permit free forward movement. A lug 16 projects laterally from that portion of the slide which connects its two spring-arms, to prevent said slide from being tilted by the end thrust of the crayon, and the firm engagement of the lug 11 at the opposite end of the slide with its teeth is insured by the spring action of saidarms.

As illustrated in Fig. 5, by pressing inwardat its free end released from the slide by running said slide forward until its hookreaches the end of the slot in the crayon tube, when the incline of the hook will engage the extension 7 of the tube and the hook will be raised thereby out of engagement with the crayon.

The erase r cap 17 consists of a tubular metal body 18 of a size to slip closely over the rear end of the pencil body and having an eraser 19 of any suitable material secured in its open end. In the side of the body 18 is a longitudinally extending depression or groove 20 formed with a roughened or corrugated bottom 21 forming an abrasive surface. This depressed port-ion 20 of the'cap 'enters the longitudinal slot in the body. of the pencil when said cap is slipped on, or

i the end of the body may be cut. away to re- I being provided with a slanting surface ceive the depression. The point of the crayon is sharpened by removing the cap, placing the end of the crayon in the groove, and moving the crayon back and forth in contact with the abrasive surface until the lead is cut away tothe desired point.

Hav' thus fully described the invention what I c aim is:-

1. In a pencil, the. combination with a body and'a crayon-tube in said body, of a slide within the tube formed with means for engaging and holding a crayon, said means adapted to engage the end of a crayon forced into said tube to raise said means into engagement with the crayon.

2. In a pencil, the combination with a 'body and a crayon-tube in said body, of a slide, a spring-arm on said slide within the 7 tube formed with means for engaging the crayon and with a slanting surface at its free endcadapted to engage the end of a crayon forced into the tube to flex the arm and raise. said means into engagement with the crayon.

3; In a pencil, the combination with a body having a longitudinal slot and a crayon-tube in the body having a longitudinal slot opposite the slot in the body, of a member having opposing spring-arms ada t-- ed to be interposed between the body an a crayon 1n the tube, one of said arms engagmg the body at its free end and the other engaging the upper side of the crayon atits free end and means on the arm engaging the body, which means project through the at its free endand provided with a projection extending'through the slot in the body, and the lower arm engaging the upper side of a crayon Within the crayon-tube at its free end. I

5'. In a pencil, the combination with a cylindrical body formed of sheet metal and having a longitudinal slot and a'crayon-tube in the axis of the body having a slot 'opposite the-slot in the body, of'a series of teeth formed on the body by turning the edge of the metal at one side of the slot inward and .cutting notches therein, and a member consisting of parallel spring-arms the upper one of which has its free end bnt laterally to engage the said teeth and is provided with 1 lug projecting through the slot in the body and the lower arm is provided at its-free end with a projection to engage the upper side of a crayon in the crayon-tube.

6. In a pencil, he combination with a body having a slot, and a crayon tube in said body having a slot opposite the slot in the body, of a slide movable in the tube and extending outward through the slot in the body, a spring-arm'on the slide within the tube, a hook on the free end of the springarm. formed with'a slantin forward end adapted to. engage the end 0 the slot in the tube and be lifted thereby to release a crayon, and means for holding the slide in tile position to which it is moved along the s ot. Y

- 7. In a pencil, the combination with a body having a slot and a crayon tube in the body having a slot opposite the slot in the body, of a slide movable in the tube, a longi tudinally extending spring-arm on the slide within the tube, a hook on thefree end of said arm to engage and hold a crayon, a

shoulder on the arm at the base of the hook to form an abutment for the end of the crayon, and means for holding the slide against the end thrust of the crayon.

8. In a pencil, the combination of a body formedof sheet metal with a longitudinal slot, a series of teeth on the body along the slot, a crayon tube in the body having a slot opposite the slot in the body, a slide consisting of two longitudinally extendin spring-arms connected at one end, one 0 said arms being adapted to lie within the tube, a hook on the free end of the arm within the tube to engage and hold a crayon, a shoulder on said arm at the base of the hook, a lug on the upper arm projecting through the slot in the body, a lug on the free end of said arm to engage the teeth on the body,

and a laterally extending lug on the end of end,-of a cap adapted to fit over and close' said end of the body, and a groove in said body, the'bottom of said groove being corru I cap having an inner abrasive surface. gated to form an abrasive surface.
