. 1- i' A PENCIL ATTACHMENT.

Appiieation led May 28, 1928. Serial 110,281,830.

n means may be employed for any other purl poses for which it is foundapplicable.

A furtherobject of .the invention is to provide, in a lmanne-r .as hereinafter set fort-h, an attachment of .the class referred to. including a pivoted, spring controlled element .designed primarily as a. .clip fastener and envelope opener, .but of such form as to enable it Vto be employed for' any other purposes for which it is formel applicable.

A further object of the invention to provide, in ya nia-nner as hereinafter setforth, an .attachment of the kclass referred to including a -pivoted, spring controlled element normally providing .a .clip fastener for the pencil capable `of being used, when shifted from normal .position as an .envelope opener vvor for any other purposes for which the element may be found applicable.

Further .objects of the provide, in a manner as hereinafter Aseit forth, an attachment for pencils which isfsimple in its construction `and arrangement, strong, durable, compact, readily installed with re,- spect to :a pencil, thoroughly-,eici-ent in its fuse, .conveniently manipulated, and -compara- .tively inexpensive to manufacture.

With the 'foregoing and other .objects 'in view invention consists of V.the nevel construction, coinbinationand arrangement of parts Vas hereinafter more specifically .der scribed, and illustrated in the accompanying drawings, .wz-herein is .shown .an embodiment .ofthe invention, but it is to lhe understood .that changes, `variations .and modifications can be resorted to which fall within'thescope vof the .claims hereunto l In'thek drawings wherein .like reference characters denote corresponding parts :throughout .tlieseveral vieuvsnvwV l Y Y Y Figure 1 is .an .elevation ofthe pencil attachinent :as .applied to one 'end ofV ay pencil and with the attachment positioned asa clip fastener; j` o Y Figure 2 is a sectional eleva-tion of the attachment- .and pencilv andv illustrating :the attachment in a position to be employedas an .envelope opener or forany otherfpulpose for *whichitcan-be v invention i .are .to

g Figure 3 is a fragmentary view in section of the attachment as applied to the pencil.

. Figure 4 is an elevation of the attachment in envelope opening position.

Figure 5 is a section on line 5-5 Figure 2. Referring to the'dra-wings in detail 1 generally indicates a pencil of that type includinga tubular body portion 'having a tapered end through which the lead '2 is fed. The pencil is shown by Way of exalnplefor the purpose of illustrating the attachment, in accordance with this invention, asapplied'to the inner end of the body portion ofthe-pencil. The innerend ofthe body poration is reduced, as attoincrease its inner diameter kof the pencil at' the inner end thereof thereby providing an annular shoulder on the inner face of the body portion-of the `pene-il. The attachment indicated generally .at .5 extends into the inner end of the body pory tion of the pencil, abuts against the shoulder 41and frictionally engages with that part of .the innerface of said body portion of greater diameter. The attachment whenconneeted tothe Iend of the body portion of bhe pencil abuts against the innerend edge .of said body v`j portion. v

Thev attachment 5 includes a. tubular VVbody portionor sleeve f6 provided intermediate-.its ends with a diametrically disposed partition 7 formed with a central :opening 8. v The sleeve 6 has an end 9 of reduced outer eter which engages and seats on the reduced portion 3 of the inner end of the body7 por- .tion :of :the pencil.

The reduced part 9 ofthe sleeve 6 is at the inner endV thereof. The sleeve isvformed with a lengthwise disposed slot ,10 which lopens at the outer 4edge of the sleeve .and thatpart of the inner face :of Ithe ksleeve 6 opposite the slot 10 is cut away as at 11 to provide a clearance. V,The outer end of the sleeve 6'i s`cut away as iat 12 to form a seat which opposes the slot 10.

Y Pivotalzly connected to and arranged* Within Athe outer end of the sleeve 6, as well las bearing against the disc 114is a shiftable angle-shaped elementvwhich canbe .used as yaclip Vfastener,-an envelope openerlor for any otherpurposes for which it is found ap-r plicable. The said element includes an arm 16 disposed lengthwise with respect to the length of and exteriorly ofthe pencil 1. One end of the arm 16 is formed integral with an inwardly extending, right angularly disposed arm 17 having` a cam 18 extended laterally from one side thereof and with such side further provided with a notch 19. The cam 18 pivots on a pin 2O which is :fixed to and extends diametrically with respect to the outer end of the sleeve 6. The pin 20 is eccentrically disposed with. respect to the opening 8 and also is disposed at one side of the longitudinal median of the arm 17. The free end of the arm 10 is outwardly curved to facilitate the positioning thereof when employed as a clip fastener. The arm 16 is normally arranged in parallel spaced relation with respect to the pencil.

The disc 1li snugly abuis against the noni notched side of ths arm 1'? and acts to main- Cil tain the arm 16 in the position shown in Figure 3 when said arm 1S is functioning as a clip fastener. ldhen the arm l1 6 is swung from vthe position shown in Figure 3 to that shown in Figure 2 the disc 141: is engaged by the cam 18. When the arm 1G is swung to the position as shown in Figure 2 the notch 19 receives the seat 12 and the walls of said notch 19 in connection with the spring controlled disc 14E maintain the arm 16 in the position as shown in Figure 2. The opening 8 provides a clearance for lthe shifting movement of the stem 13 and the pivoted element is swung to extended or from extended to non-extended position as shown in Figures 2 and 3 respectively.

Secured within the sleeve 6 and projecting from the inner end thereof is a combined casing and coupling element 21 for the sleeve G and said element 21 frictionally engages withthe inner face of the body portion of the pencil 1. The element 21 is formeel with` 4 spaced ribs 23 extending lengthwise thereof which frictionally engage with the inner face of the body portion of the pencil 1 whereby a frictional clutch is set up between element 21 of the pencil so the sleeve 6 will be rigidly maintained in position on the end of the pencil body.

The element 21 provides a storage chamber 22 for pencil leads and the inner end of said element 21 is closed by a removable cap 211. which carries an erasing member 25.

The structure referred to with respect to the attachment provides a spring controlled, eccentrically pivoted, cammed angle-shaped element, and a supporting means therefor for coupling said element to an end of the pencil body, and with the element arranged with respect to said body to permit of its being conveniently` shifted from and to noneitended position, and when in non-exi ended yposition functioning as a clip fastener for the pencil and when in extended position vunderstood although the preferred'embodiment of the invention is as illustrated and described, yet it is to be understood thatY changes in the details of construction can be had which will fall within the scope of the invention as claimed.

What I claim is:

1. in attachment for the purpose set forth comprising a spring controlled, eecentrically pivoted, L-shaped element, said element having a cam at one end, the pivot for said element being arranged at the eannned end of the latter, and tubular supporting means for the pivot for said element, saidmeans and pivot providing for coupling said Velement to one end of a pencil body. y

2.
