ERASER FOR TYPE'IWRITERS- Specification of Letters Patent.

Patented April 30, 1907.

Application filed January 28, 1967. Serial No. 354,462.

. vented a new and Improved Eraser for T e-Writers of which the following is a fu li: clear, and exact description.

This invention is an improved eraser for typewriters, and is designed to render writ mg'invisible as produced by the machine,

without the need of rubbing it from the. paper, as is the-usual practice,'-but efiecting the erasin by reproducing coincident there with the c aractersdesired to be erased and in an ink of the same color as the background of the paper or other material on which said characters appear. This is accomplished by shifting the typewriter carriage back to the point where the writing to be removed or error begins, and after inserting between the machine ribbon and paper my improved eraser comprising a ribbon inked in the color of the background of the paper,.the error is repeated by striking the proper keys.

Reference is to be had to the accompanying drawings forming a part of this specification, inwhich similar characters of reference indicate correspondin parts in all the figures.

. Figure 1 is a front e evation of one embodi- 'ment of my invention; Fig; 2 is an edge view of the same Fig. 3 is an elevational view corresponding to Fig. 1, but with the ribbons removed; Fig. 4 is a face view of the uninked ribbon; Fi 5 is a like view of the inked ribbon, an Fig. 6 is a cross section through the ribbons shown in Figs. 4 and 5'when attacllliled. I 1

can'yin out In invention, em 0y a suitable holdir for a1 ribbons, the pre ferred embodiment of which consists of a spring fork,

I preferably made of a single piece of wire 1 out upon itself at its center, as shown in Figs. 1 and 3, with the wire formed into a fork at its "free ends, comprising spring'arms 2 separated a suitable distance, and each provided'with a hooked extremity 3. At an intermediate point of the holder, the handle end thereof is constructed with an offset portion 4, as best shown in Fig. 2, said ofiset portion adapting the holder to be conveniently located in position when in use. In connection with the holder is an uninked ribbon 5 and a ribbon 6, whichare sewed or otherwise secured together at oppositeedges, as indicated at 7 in Figs. 1 and 6. These ribbons are of such extent that when applied to the spring arms 2, as indicated in Fig. 1, they will draw said arms together, thus adapting the holder to keep the ribbons stretched under slight tension, said tension being insuflicient to cause the ribbons to be punctured or torn when struck by the typewriter keys. The hooks 3 of the arms 2 prevent the ribbons from slipping therefrom when applied to the holder.

To erase or ink out the error or other characters produced by the typewriter, the eraser is inserted with the ribbon.6 ad'acent to the paper or other material on whie said characters a pear, it, of course, bein understood that the ribbon 6 is inked in t e same color as the background of the aper. With the ribbon 6 covering these cl iaracters, the error is repeated coincident therewith by striking the pro er keys, thus acting to color the characters t e same, or-substantially the same as the color of the paper on which they are produced, and thereby rendering them practically invisible.

The uninked ribbon 5 not only forms in connection with the ribbon 6 a 100 adapted to be held on the arms 2, but also s hields the ribbon 6 from the typewriter ribbon and prevents the ink of the latter from being stamped thereon.

The word color as used in the foregoing description, as also in the claims hereunto annexed, is intended to cover both white and black.

It is obvious thata construction embody ing my invention widely differing from" the construction described, may be made within the scope of the appended claims; and I claim al such as fall within the scope thereof. Having thus described iny invention I .claim as new and desire to secure by Letters v Patent: 7

1. Aneraser for inking out characters produced by a typewriter or the like, comprising an inked ribbon of the same color as the background of the paper on which said characters appear, and spring arms for holding said ribbon in an outstretched position.

2. An eraser for inking out characters produced by a typewriter or the like, comprising a holder with spring arms, and an inked and uninked ribbon secured at opposite edges, carried by said arms.

3. An eraser for inking out characters as produced by a typewriter or the like, comprising a holder withfspiing arms, the latter aving hooked extremities, and an inked and an uninked ribbon secured at opposite edges, v

carried by said arms.

4. A process for erasing characters as pro duced on pa er or other material by a typewriter, whic consists in re roducing in a color corres onding to the col dr of the paper, the same 0 aracters by the typewriter on said paper coincident with the characters desired to erase.

5. A process for erasing characters as produced on paper or other material by a typewriter, which consists in covering said characters with a'ribbon inked in the color of the background of the paper, and then repeating the same characters by the typewriter on said-paper coincident with the characters de sired to erase.

6. An eraser for rendering. invisible the characters produced on paper or other material by a-ty ewriter, com rising an inked ribbon of a colbr correspon ing to the pa er on whichsaid characters are produce and uninked ribbon for shielding one side of saidinked ribbon.

8. An eraser for rendering invisible the characters produced on paper or other material by a ty ewriter, com rising an inked rib bon of a co or correspon ing to the aper on which said characters are produce an uninked ribbon for shielding one side of said inked ribbon, and means for holding said rib bons in an outstretched position.

In testimony whereof I have signed my name to this specification in the presence of two subscribing Witnesses. I
