My present invention h as reference to In this connection it maybe advisable to writing implements, and my object isi the state that in my experiencev I have found provision of simple, cheaply constructed but that the rubber erasers attached'to the vordithoroughly eiiicient means for securing rubnary typesofpencils wear away long before Y n 5 ber erasers on the ends of pencils or like the pencil is completely.' used, especially 55 writing implements. l `when a. comparatively great amount of era- A further object is the provision of a eures are required, which'is especially true means for this purpose that includes a sleeve with respect to pencils employed by Aschool of comparatively thin metal which comprises children. I have also found thatv the ordi- 10 two hingedly connected sections, the free end nary manner of fastening an eraser to the 60 of one of the sections having swingably aspencil is notaltogether satisfactory, as` pressociated therewith a latch rod, the other secsure upon the eraser not infrequently causes tion having a hook-like catch to be engaged the same to become disengaged fromfits by the latch rod for holding the sections fastening means and consequentlythe eraser Y closed to tightly compress therebetween a is rendered useless. Itv will bel noted with 65 rubber eraser, the latch rod having one of my improvement that the eraser is not let its ends formed with a prong designed when in the end of the pencil, nor is the pencil the said latch yrod is turned to latching po provided with a `fixed means for fasteningsition, to enter the side of the pencil or like the eraser thereon.

While my improvement may be employed received inthe catch 3 of the ysection l when 95 Prior to bringing the sections of the sleeve together and clamping'or latching the same in a manner as just described, there is arranged in the said sleeve the inner lportion of a cross sectionally round rubber eraser 10.

In the showing of the drawings the body of Vthe pencil 9 has angle faces, but the end thereof` on which the sleeve is arranged is cross sectionally rounded, as at 10', andthe said rounded portion affords an inner shoulder 11 against which theinneredge of. the sleeve rests. n

In Figure 5` the sleeve'is illustrated as a split sleeve, one edge'thereoi' being formed with a hook-shaped catch 12 tob'e engaged by the oii'set portion 13 of the latching, rod 14,` the lat'ehi-ng rod heiligk similar to that previously described and having` itsV ends journaled i-n barrels in the endI oztthe sleeve notprovidedV with the hook-like catch 12.

In Figure 6' the construction is similar to that described in connection with Figures 11 Zandj 3, except' the rounded portions or barrels V15 through which the pivot pin-16 passes are inwardly directed. In this instance'the barrels may enter a groove in the eraser 10 anda groove in the pencil or'like writing; implement, or thek barrels which con.- tact withA the rubber eraser may be forced thereintoto more eilecti'vely hold the eraser inthe sleeve.

The simplicity of the construction and the advantages thereorn will, it is thought, be understood' and 'appreciated by those skilled in the Yart so that lfurther detailed description will not be required',

llavi'ngl described' thei'nvention, I claim: '11. A. means for attaching a rubber toa pencil' or like writing implement whose body Vis ofv penetrabl'e material", comprising.v 'a
