Application January 2, 1937, Serial No. 118,712

3 Claims.

This invention relates to eraser attachments for pencils, pens, and the like, and has for its principal object the provision of an eraser having a plurality of erasing ends, eachof which may be of a diiferentquality of erasing material or designed for different type of erasures.

A further object of this invention is the provision of an eraser for attachment to pencils, pens and the like, having a plurality of. erasing ends projecting outwards at right engles to the axis of the pen or pencil whereby said pen or pencil will be prevented from rolling when placed upon an inclined surface.

A further object of this invention is the provision of an eraser, for attachment to a pencil, pen or the like, of novel and useful shape and construction which willprovide a relatively blunt erasing surface for general erasing and-a sharp, bevelled erasing edge for detail work which will permit erasing a character in closely written or printed work without marring the adjoimng characters.

A further object of my invention is the provision of an eraser for attachment to a pencil, pen or the like, havinga plurality of erasing ends, one of which is designed for coarse work and one end for fine or detailed work, thus providing for economy and long life of the erasing material.

A further object of my invention is the provision of an improved form of means for attaching said eraser to a pencil, pen, or the like in a secure and rigid manner.

A further object of my invention is to provide an eraser attachment for pencils, pens and the like which is striking in appearance, which is cheap and simple to manufacture and which is convenient and economical to use.

These and other objects which will later appear are best understood by reference to the following specification taken in connection with the accompanying drawing in which:-

Figure 1 is a side elevation of a pencil showing my improved form of eraser and attachment mounted thereon,

Figure 2 is a sectional view of the same taken along the line 22 of Figure 1 and looking in the direction of the arrows,

, Figure 3 is a fragmentary sectional view of .the same takenalong the line 33 of Figure 1, Figure 4 is a fragmentary side elevation of a pencil showing my improved form of eraser attached thereto by an optional attachment means, Figure 5 is a sectional view of the same taken along the line 55 of Figure 4 and Figure 6 is an enlarged perspective view of the eraser of my invention.

Referring now in more detail to'the drawing the numeral Ill denotes a conventional lead'pencil staff to the end of which, the eraser member II is attached. The eraser member II, as shown in Figure 6, is made of rubber or other erasing material,. and has a cylindrical portion Ila having a flat end Ilbat right angles to the axis of the cylinder. Formed integrally therewith is the portion llc of square cross section and having one face Hd formed at right angles to the axis of. the cylindrical portion Ila and a second face I le forming an oblique angle with said axis thereby providing the sharp erasing edge Hf.

The pencil staff I0 is provided at one end with a depression Illa, the form of said depression being that of a section of a cylinder, the axis of said cylinder being at right angles to the axis of said pencil staff H). A portion of the cylindrical part I la of eraser ll next adjacent the square portion He is received into the depression Illa and'secured therein by the U-shaped strap member l2, the straight ends of which enclose a portion of the end of the pencil staff l0, being formed to fit closely there-around. Said ends of the U-shaped member, l2 are enclosed and secured against the pencil staff Ill bya sleeve I 3 which bears against the outwardly turned ends l2a of the U-shaped strap member l2. Indentations |3a serve to hold the parts more securely.

In the optional form of my invention as disclosed in Figures 4 and 5 the eraser member H is aflixed to the end of the pencil stall Ill by means of the tubular sleeve I 4 which in turn is secured to the pencil staff by crimping or indentations I do, or by any other suitable means. The tubular sleeve I4 is provided with two tapered tongues Mb which are bent toward one another to enclose a part of thecylindrical portion 1 la of eraser member ll adjacent theface Hd. Indentations Mc may be used to further secure the eraser member H to the tapered tongues Mb.

It will thus be seen that I have provided an eraser attachment for pens, pencils and the like wherein an eraser member having a fiat end and a sharp end is mounted at its approximate center upon the end of a pen or pencil at right angles to the axis thereof, presenting two erasing surfaces, one for coarse work and one for delicate work, at the same time providing means whereby the pencil is prevented from rolling upon inclined surfaces, and forming an assembly of novel and striking appearance.

While I have shown and described certain hence I do not limit myself to the device as shown, except to the extent indicated in the following claims.

I claim: I I V 1. An eraser attachment for pencils, pens and the like, comprising a rubber eraser member having a cylindrical portion and a portion of square cross-section formed integrally and joined end to end therewith, the free end of said cylindrical portion being at right angles to the axis of the cylindrical portion and the free end of the portion ofsquare cross-section forming anoblique angle with said axis, a pencil staff having a groove formedin one end thereof to receive the cylindrical portion of said eraser member, a U-shaped strap member, having elongated ends with outwardly turned tips, said strap member'partially encircling the cylindrical portion of said eraser member and the elongated ends of said strap member lying along the sides of said pencil stafi, and atubular sleeve encircling said ends and the end of said pencil stail' and abutting said outwardly turned tips.

2. An eraser attachment for pens, pencils and the like, comprising an eraser member of suit thereof.

acc

able erasing material, having a cylindrical portion and a portion of square cross-section formed integrally and joined end to end therewith, the free end of said cylindrical portion being at right angles to the axis of said portion and the free end of the portion of square crosssection forming an oblique angle with said axis, a pencil stat! having a groove formed in one end thereof to receive the cylindrical portion of said eraser member, a tubular sleeve for attachm'ent to the end of said pencil staff, and tapered tongues on opposite sides of said sleeve and at one end thereof, said tongues being bent to enclose the central part of the cylindrical portion of said erasermember.

3. An eraser attachment for pens, pencils and the like, comprising an eraser member of suitable erasing material having a cylindrical portion and a portion of square cross-section formed integrally end to end therewith, the free end of said cylindrical portion-being formed at right angles to the axis thereof, and the free end of the portion of square cross-section forming an oblique angle with said axis, and means for supporting said eraser member upon the end of a pencil stafl', the axis of said stafi being at right angles to and intersecting the axisof said eraser member substantially at the center DE mvnm M.
