Description

UNITED STATES PATENT OFFICE.
v D. B. SPOONER AND H. B. SPOONER, OF SPRINGFIELD, MASSAoHUSETTS.
MODE .OF COLORING PHOTOGRAPHIC PICTURES 0N GLASS.
Specification forming part of LettersPatent N0. I5A97, dated August 5, 1856.
To all whom it may concern.-
Be it known that we, D. B. SPooNER and H. B. SPooNER, of Springfield, in the county of Hampden, in the State of Massachusetts, have invented new and useful Improvements in C01- The following is the process adopted: Af-.
ter the picture is thoroughly washed and dried, proceed with a brush'to cover any portion of the picture not designed to take the color with a solution of gum, or any other substance insoluble in the coloring-solution, but soluble in any other liquid in which the coloring-matter is not soluble. e. 9., take a solution of gum-arabic in water and apply it to a portion of the picture. Now take a solution of turmeric in alcohol and pour it upon the collodion surface of the picture, and you immediately get a deposit of the coloring-matter between the collodion and the glass. The portionof the picture covered with the gum not being penetrated by the alcohol is protected from the color, while all other portions are colored. Then, by washing the picture in water the gum is dissolved and washed off,
and the parts uncolored may remain in their natural state without color; or by applying the gum solution to the portion already colored with a part of the uncolored portion another color may be produced by the use of another pigment, in the same manner as before described. -In this manner any number of colors may be produced; or when a small portion only of the picture is to be colored the whole of the picture may be colored and dried, and then that portion which is to retain the color may be covered with the gum solution, and the coloring-matter not protected by the gum may be extracted with alcohol or other solven and the gum washed off as before.
The advantages of our invention consist in depositing the coloring-matter in its various tints on the front side of the picture, between the collodion and the glass, instead of coloring the fibers of the collodion, or the upper side of it, asis common, which does not Show through to the positive side of the picture on account of the opacity of the silver deposit which forms the picture.
We do not claim the coloring of a picture all over with a single tint; but
