1 Claim. (Cl. 120-36) This invention relates to pencil eraser attachments and more particularly to an attachment for a pencil eraser that is to be utilized with a typwriter in which the attachment is slidable on the pencil and is provided with a cup formation below the eraser to catch the particles erased from the surface of the paper while in the typewriter.

It is an object of this invention to provide an attachment for a pencil eraser which is utilized to catch the particles erased from a paper while mounted in a typewriter.

A further object of this invention is to provide a slidable attachment for a pencil eraser that may be utilized to catch particles that are erased from a paper while mounted on the roll in a typewriter.

A still further object of this invention is to provide a flexible tubular body in which an eraser is mounted in one end thereof and a cup is mounted in the opposite end thereof so that the tubular body may be bent to provide an eraser holder for a typewriter wherein the erased particles from the paper will be caught in the cup formation during the erasing operation.

A still further object of this invention is to provide an attachment for the common disc erasers used in conjunction with a typewriter in which the attachment is a pivotally mounted catch all tray which will remain suspended from the disc eraser to catch the particles erased from the paper while the paper is mounted in a typewriter.

Further objects of this invention may be apparent by reference to the accompanying detailed description and the drawings in which Fig. 1 illustrates a side elevational view of the pencil eraser and cup attachment schematically illustrated with a typewriter roll and paper.

Fig. 2 is plan view taken on line 2-2 of Fig. 1,

Fig. 3 is a side elevational view of a further embodiment of this invention,

Fig. 4 is a side elevational view of a still further embodiment of this invention, and

Fig. 5 is a front elevational view taken on line 5-5 of Fig. 4.

Referring to Figs. 1 and 2 there is illustrated a pencil eraser provided with an erasing material 11 and slidably mounted thereon is an attachment 12. The attachment 12 is shown as formed of a rigid material such as sheet metal which may be readily formed with overlapping elements 14 and 15 which form the embracing portion of the clip, that is, to embrace the barrel of the pencil 10. It is apparent that the elements 14 and 15 may be sprung outwardly to insert the barrel of pencil 10 and likewise may be pressed inwardly to form a frictional grip with the barrel of the pencil 10. The body portion 16 of clip 12 extends below the pencil to form a cup shaped area 17. Likewise the cup shaped area may be slightly wider than the clip formation formed by elements 14 and 15. The cup formation should not be 2,933,066 Patented Apr. 19, 1960 too wide as the attachment may remain on the pencil and be carried with the pencil at all times. The cup formation 17 and particularly the edge 18 should be formed smooth and round so that there is little or no possibility of leaving a mark on the typewriter paper during an erasing operation. Likewise the interior of cup 17 should be formed with a rough surface so that the particles of erased material that fall therein will tend to remain within the cup and not be readily thrown from the cup during an erasing operation. Of course it is apparent that after each erasing operation that the cup 17 is to be cleaned. it is also apparent that due to the small size of this attachment it lends itself to the same erasing operation for each carbon copy and thus prevents the erased particles from falling between the papers and causing unsightly marks.

Referring to Fig. 3 there is illustrated a still further embodiment of this invention in which a flexible tubular body 20 is provided. The body 20 may be approximately of the same size as a pencil or pen. The flexible body 20 is provided with an eraser 21 mounted in one end thereof and is further provided with a cup shaped formation 22 mounted in the opposite end thereof. In use it is apparent that the flexible body 20 may be bent into the form illustrated in Fig. 3 and becomes a convenient device for erasing especially with a typewriter when the particles of paper are erased, the particles will drop into the cup 22. The cup 22 may be frictionally mounted within the tube 20 so that regardless of' the position of erasing, the body 20 may be twisted or bent so that cup 22 will be below the eraser 21 and cup 22 may be turned in body 20 so that its open end will always remain directly under the eraser 21.

Another form of this invention is illustrated in Figs. 4 and 5 in which the common disc eraser 30 is illustrated and attachment 31 is pivotally afiixed to the disc 30 at its center 32 either with the metal barrel found in the disc eraser or by using a separate pin 33 mounted through this barrel. The attachment 31 is generally triangular in side elevation. Referring to Fig. 5 the attachment 31 is formed with an open .mouth area 34 which is the catch all. The mouth 34 is of course somewhat wider than the disc eraser 30 so that any twisting or turning of the eraser during an erasing operation will still drop the erased material into the mouth 34 of the attachment 31. The attachment 31 is so seated that the mouth 34 will always tend to press against the paper as it normally extends beyond the contact face of the disc 30 but since the atttachment 31 is pivotally attached, there is little or no pressure by the front lip 36 of mouth 34. It is apparent in this embodiment that the eraser must be used in a vertical position although it may be twisted or turned slightly from the vertical in order that the catch all attachment 31 may be effective in catching the erased material.

Various changes may be made to the embodiments disclosed hererin, that is, the pencil eraser 10 may be entirely an eraser and not necessarily a pencil and the attachment may still be utilized in the same fashion. Likewise, although the embodiment illustrated in Fig. 3 is suggested as a flexible tubular body, the complete structure may be similarly constructed of a flexible rubber as a single unitary structure without departing from the spirit of this invention. Although the catch all device illustrated in Figs. 4 and 5 is combined with a disc eraser, it may be similarly formed wider to be attached to any flat type eraser without departing from the spirit of this invention and this invention shall be limited only by the appended claim.

What is claimed is:
