' J. SCHNEIDER PENCIL CAS ING Filed Oct, 14, 19430 ATroRNEYs Patented July 21, 1931 JOI-IN SCHNEIDER, OF ROSELLE PARK; NEW JERSEY PENCILr oAsINe Application filed October 14, 1930. Serial No. 488,595.`

rlhis invention relates in general topencil casings or holders, and one object ofthe invention is to provide a novel andl improved nary lead pencils comprising a rod or stick:

of lead encased in wood or the like. Grenerally, suchlead pencils, as the result'of repeated sharpening, become so short'as to be 1o useless, that is, the pencils eventually become so short that they cannot be conveniently gripped for writing. Y

Another object of the invention is to. provide a'holder or casing for pencils within which the pencil may be clamped with one ond projecting from the holder, said holder including meansfor sliding the lead outwardly from the wooden casing of the pencil, the holder serving as an extension grip for ma-V 20 nipulating the pencil during writing operations and permitting utilization of the entire.

and inexpensive in construction; to provide.

35 a pencil holder so constructed astobe capable of first loosening the lead in a pencil for slid-H ing movement, and thereafter propelling the lead from the pencil to compensate forshortening thereof byuse, and to obtain other ad-` vantages and results as will be brought out by the following description.

Referring to the accompanying drawings, in which corresponding and like parts are designated throughout the several views by the same reference characters,

Figure 1 is a vertical longitudinal sectional view through a pencil holder embodying my invention, showing the same utilized for initially loosening the lead in a pencil;

Specifically describing the embodiment/of ahe invention shown in Figures 1-5, inclusive, the holder comprises a main tubular casing section lto receive therethrough a wood encascdlead pencil 2. One end of the casing section is exteriorly screw threaded at 3 and has an interior circumferential groove l and a corresponding exterior rib 5 inwardly of the screw threads 3. Within the groove -flis arranged a splitmetal ring 6, and threaded upon the end of the casing section is aclamping sleeve 7 the inner end 8 of which abuts the rib 5 when the sleeve is screwed upon the casing section;Y The casing sectionl is formed with a plurality of longitudinal slits `9 which in- 7 tersect` the rib. and groove 4 and 5 so that the walls of the casing section may be compressed inwardly.

In securing a pencil in the casing section, the sleeve, 7 is unscrewed and the pencil is slipped into the casing past theY split ring 6. The sleeve 7` is-thenscrewed onto. the casing section until-the end` S thereof engages the rib` 5which causes the-walls Vofthe casing sectionto be compressed so .as to force the split ring 6 tightly intocon-tact with the pencil 4and thereby clamp the pencil in the casing.

The other end of the. casing section 1 is interiorly screw threaded at 1,0 to'receive an actuating memberll. This member 11 has both ends'exteriorly screw threaded at 12. and 13 to fit the threads lOof the: casing section 1,so that the member can bescrewed into thecasing sec-` tion. The ends of the actuating member have the respectiveaxialrecesses lllvand 15, at the basesof which are formed sockets 16`and 17 to removably receive a ppush rod 18 and a leadpropelling rod-19.v A cap 2O carrying an eraser 21 maybe screw threaded upon either end of the actuating member.

For the purpose of initially loosening the lead 22 in the lead pencil 2, that is, to initially break the hold ot the glue upon the lead, the push rod 1S is fitted into the corresponding socket 17 andthe actuating member is screwed into the casing section 1 so that said push rod engages the end of the lead, as shown in Figure l. Relative rotation of the casing section l and the actuating member 11 will then cause relative longitudinal movement of the casing sections which in turn will exert pressure on the lead and loosen it in the casing of the pencil. The shorty push rod 18 is utilized to avoid possibility of the rod being bent or distorted during this operation.

The actuating member is then removed from the casing section 1 and reversed, whereupon the lead-propelling rod 19 is ins-erted in the socket 16 and the actuating member is screwed into the casing section until the rod 19 engages the lead. The cap 2O is applied to the projecting end of the acuating member, as shown in Figure 3 of the drawings. Upon relative rotation of the actuating member and the casing section 1, the lead 22 will be propelled from the end of the wooden body ot the pencil, as shown in Figure 3 of the drawings.

Pencils of diiierent lengths may be readily accommodated in the holder due to the adj ustable clamp means, and the lead in the pencils may be exposed tor use either by sharpening as usual, or by manipulation of the actuating member l1, or both.

Another form of adjustablel clamping means for securing the pencil in the casing is shown in Figure 8 of the drawings. In this form of t-he invention the casing has an exterior circumferential rib or projection 35 from which are punched inwardly of the casing a plurality of teeth or prongs 36. The extremity of the casing section is screw threaded at 37 and has screwed thereon a nut 38 like the nut 7, the inner end of said nut being adapted to engage the rib 35. To clamp the pencil in the casing, the nut 38 is loosened and the pencil is slipped into the casing past the prongs 36. The nut is then screwed on the casing until its inner end engages the rib 35, which causes the prongs to be pressed into the body of the pencil so as to securely hold the pencil in the casing. The perforations produced by the punching of the prongs 3G Jfrom the casing render the casing suiiiciently contractible to permit the prongs to be so pressed into the pencil, said perforations serving the same function as the slits 9 shown in Figures 1 3, inclusive.

Obviously many modiiications and changes may be made in the details of construction of the pencil holder without departing Jfrom the spirit or scope oi' the invention, and therefore l do not desire to be understood as limit ing myselic except as required by the following claims when construed in the light of the prior art.

Having thus described the invent-ion, what I claim is:

1. A pencil holder comprising a casing` to receive in one end thereof a pencil which inchicles a body and a lead slidable therein, meansv on said end of the casing section to clamp said pencil against movement therein, and means in said casing to engage and push said lead from said body.

2. A pencil holder comprising a casing to receive in one end thereof a pencil which includes a body and a lead slid-able therein, means on said end of the casing section to clamp said pencil therein, and means screw threaded in the other end of said casing to engage and push said lead from said body upon relative rotation of said means and said casing section.

8. A pencil holder comprising a casing to receive in one end thereof a pencil which includes a body and a lead slidable therein, said end being exteriorly screw threaded, formed with longitudinal slits and having an exterior rib intersected by said slits, a clamping sleeve screwed on said end of the casing to engage said rib and compress the walls of said casing into contact with the body oi' said pencil to clamp the pencil in the casing, and means in said casing to engage and push said lead from said body.

el. A pencil holder comprising a casing to receive in one end thereof a pencil which inclinV es a body and a lead slidable therein, said end being exteriorly screw threaded, formed with longitudinal slits and having an interior circumferential groove adjacent said slits, a split ringin said groove, and a clamping sleeve screwed on said end of the casing to compress said split ring into Contact with the body of said pencil to clamp the pencil in said casino.

5. A. pencil holder comprising a casing to receive in one end thereof a pencil which includes a body and a lead slidable therein, said end being exteriorly threaded and having an exterior circmnferential rib at the inner extremity of the threads, the casing having a plurality of inwardly projecting prongs stamped from said rib, a clamping sleeve screwed on the said end of the casing to engage said rib and compressing the walls of the casing to torce said prongs into the body of said pencil and clamp the pencil in the casing, and means in said casing to engage and push said lead from said body.
