April 7, 1964 M. B. BARA ERASER CLEANER Filed Nov. 15, 1962 FIG.

INVENTOR. MARY B. BARA BY MW BM ATTORNEY United dtates Patent Ofiice 3,127,714 Patented Apr. 7, 1964 35121714 ERASER CLEANER Mary B. Earn, 151 Van Winkle Ave, Jersey City, NJ. Filed Nov. 13, 1962, Ser. No. 236,799 2 Claims. (Cl. 51187) The invention relates generally to eraser cleaners and particularly to eraser cleaners having provisions for holding an abrasive sheet and magnetic means for holding the eraser cleaner to a typewriter or similar article.

It is among the objects of my invention to provide an eraser cleaner which will be readily attachable and detachable to a typewriter or similar apparatus in connection with which, the use of an eraser is usually necessary.

Another object of my invention is to provide a means for holding an abrasive sheet.

Another object of my invention is to provide a means for holding an abrasive sheet in which the abrasive sheet may be easily removed and replaced.

A still further object of my invention is to provide an eraser cleaner in which provision is made for receiving eraser debris.

It is yet a further object of my invention to provide an eraser cleaner which may be attached to numerous objects in the vicinity of which eraser-capped pencils or similar writing implements are used so that the eraser tip may always be kept clean and will not smudge any object to which it is applied.

Among the further objects of my invention is to provide an eraser cleaner which is simple in form, easy to use, convenient and relatively inexpensive.

These objects and advantages as well as other objects and advantages are shown by way of illustration in the drawings in which:

FIGURE 1 is a front elevational view of an eraser cleaner in accordance with the present invention;

FIGURE 2 is a rear elevational view thereof; and

FIGURE 3 is a side elevational View thereof.

Referring now to the drawings in detail, the eraser cleaner provides a mounting plate 11. The top portion 12 of the plate 11 is bent over to define a generally U- shaped top channel. The bottom portion 13 is bent over to define a generally U-shaped channel opposite the top portion 12. An abrasive sheet 14 is held in the channels defined by these bent over

portions

12, 12. The bottom portion 13 is also formed with a second bent over portion 15, which defines a gutter to receive eraser debris. The

latitudinal edges

16, 16 of the plate 11 are formed with central, inturned lips 17 which act as retainers to keep the sheet 14% in place when an eraser is rubbed over its surface, so that the sheet 14 will remain stationary and will not move out of the

channels

12, 13.

Beyond the bent over portion 12, the edge of the plate is folded over rearwardly to form a resilient top leg 18. Beyond the second bent over portion 15, the bottom portion of the plate 11 is also, like the top portion 12, bent over rearwardly to form a bottom resilient leg 19. At the rear of the plate 11, magnets 29, 20 are positioned between the

legs

18, 19 near the

latitudinal edges

16, 16 of the plate 11.

The plate 11 is made of resilient, magnetic material. Consequently, the bar magnets will be held between the top and

bottom legs

18, 19 and may be secured to the back of the plate 11 by a light coat of cement 21. Since the plate 11 is made of magnetic material, the magnetic lines of force will be directed to the

ends

22, 22 of the

legs

18, 19. Thus, any object such as a typewriter frame made of magnetic material will serve as a mounting for the plate when the

ends

22, 22 are applied to its surface. A convenient holder for abrasive sheets is thereby provided, so that erasers may be kept clean and will not smudge.

The foregoing description is merely intended to illustrate an embodiment of the invention. The component parts have been shown and described. They each may have substitutes which may perform a substantially similar function; such substitutes may be known as proper substitutes for the said components and may have actually been known or invented before the present invention; these substitutes are contemplated as being within the scope of the appended claims, although they are not specifically catalogued herein.

What is claimed is:

1. An eraser cleaner comprising,

(a) a plate having a general flat front face,

(b) longitudinal opposed channels defined by folded over portions of the top and bottom longitudinal edges of the face of the plate,

(0) a forwardly extending lip on each of the side edges of the plate,

(d) top and bottom edges of the plate, beyond the folded over portions, extending in a general rearward direction from the face of the plate,

(e) a magnet engaged between the top and bottom edges of the plate at the rear of the face of the plate and spaced inwardly from the edges of the ends,

(f) the plate composed of magnetic material,

(g) an abrasive sheet disposed in the opposed channels on the plate between the lips on the edges of the plate.

2. An eraser cleaner comprising,

(a) a plate,

(b) top and bottom longitudinal, opposed channels on the longitudinal face of the plate,

(0) a lip on each of the side edges of the plate,

(d) top and bottom edges of the plate extending in a general rearward direction from the face of the plate,

(e) a magnet positioned between the top and bottom edges of the plate and spaced inwardly from the edges of the ends,

(1) the plate composed of magnetic material,

(g) an abrasive sheet disposed in the opposed channels on the plate, between the lips on edges of the plate.
