OYSTEN 'M. SOLBERG, OF LA OROSSE, WISCONSIN.
INK-ERASER.
SPECIFICATION forming part of Letters Patent No. 429,704, dated June 10, 1890.
Application iiled July 2, 1889. Serial No. 316,301. (No specimens.)
To all whom it may concern.-
Be it known that I, OYSTEN M. SOLBERG, of La Crosse, in the county of La Crosse and State of Wisconsin, have invented certain new and useful Improvements in Ink-Erasers; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to Inake and use the same.
My invention relates to an improvement in ink-erasing blotters, the .object being to provide an inexpensive article for removing ink marks and blots from paper or similar material without scratching or otherwise injuring the surface from which the ink is effaced; and with this end in view my invention consists in a porous wafer, blotter, or other device charged or impregnated with tartaric acid.
It still further consists in certain components, as will be hereinafter fully described,
' and pointed out in the claim.
The accompanying drawing is a View of the preferred form in which the article is generally made.
A represents a small Wafer of porous or fibrous material. It preferably consists of a small rectangular piece of blotting-paper of double thickness, charged with tartaric acid; but this shape is not necessary, and it may be made in various forms.
Chloride of lime is used to neutralize the effect of the acid upon the paper after the ink has been removed, and when an eraser is to be made one of the blotters charged with the tartaric acid is moistened and passed lightly over the part to be erased. Then a little of a solution of chloride of lime is ap plied, causing the ink to entirely disappear, After this a dry blotter is used. Usually a trifle of the eraser is cut away after each erasure, so that the end is left clean and in readiness to work freely.
The erasers are made in large quantities, and may be furnished at a slight cost, and at the same time they present a neat and attractive appearance, and are easily used for obliterating marks and blots. About fifteen grains of chloride of lime are generally placed in a vial, and the latter is then filled with clean Water and well shaken. This solution is sufficient to entirely cause the ink to disappear.
It is evident that slight changes might be resorted to in the form and material of the article Without departing from the spirit and scope of my invention, and hence 1 do not wish to limit myself to the particular construction herein set forth; but,
Having fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-
As a new article of manufacture, an inkerasing blotter consisting of a fiat sheet or strip of blotting-paper charged with tartaric acid, substantially as set forth.
In testimony whereof I have signed this lspecification in the presence of two subscribing witnesses.
OYSTEN IWI. SOLBERG.
