RocEssFoR coLoniNe PHUTOGBAPHIC pemrel Specification forming part oi Letters Patent No. 50,87 3, dated November 7, 1865.

To all whomi't-ma/y concern:

Be it known that I, 1. 0.]3nrsn, of Stiiouis,

in the county of St. Louis and State of- Mis souri, have invented a new and Improved Method of Coloring Photographic Prints; and

I do hereby declarev that the following is a full,

clear, and exact description. thereof, which will enable those skilled in the art to make and use "the same.

This invention has for its principal object the cheapeuing and incrcesin g-the durability of photographic prints, and relates more perticnlarly to a new system of coloring photographsby'meaus of chemical substances which socombine with the photographic prints, when applied to them, as tcbe indestructible, either bv writenelcolml, or spirits of, turpentine, and, moreover, are superior in beauty to prints col ered 'by any of the ordinary modes hitherto known orpracticed. andcan never fade or discolor by exposure to the sun or any other-1i ght, said chemicalsubstances bei n g; of such a nature that they can be applied to the prints by any one, whether acquainted with the art ofcoloring or not. v

My new process to which I submit the prints commences when they leave the print-- plied withfin'ecamel-hair brushes, especial care being taken to remain inside of the outlines. The first-applied color-chemical, in the case of pictures of persons, being that intended to produce ailesh color upon the proper portions thereof, the component parts of which color A, as well as .those hereinafter referred to by letter, together wth the proper proporon of such materials, being described under heir 'respective letters inv the schedule of chemical colors forming part of this'specification. The rosy hue upon the checks, if necessary, is thenproduced by the proper application of the color, made and compounded as indicated under B in the schedule of colors. After having finished all flesh colors the rest of thc print-such as, for in'stance, the dress,

drapery, &c.-are then colored in the same .nianneras that described forthe flesh port-ions by the use of the proper chemicals color, a por tion of which, for producing-various colors, are described under the letters from G to F, inclus- 1ve, of annexed schedule, the colors being in each and every case applied without referenceeither to the lights or shades of the print. The print, after thus having been fully or sufficiently colored, is then placed in the toningbath, which is composed of fifty (50) grains acetate sode to eight (8) ounces oi water, together' with about twenty (20) drops of solution of chloride of gold, where it ifs allowed to remain until sufficientlytoned, when it is fixed in hyposulphate of soda, and finallyfin iSllBLl by being washed for about a half of an hour in water to remove the hyposuiphate,

From the above it will be seen that a great saving of time is here made, as heretofore, with the old method, it wasneces ary that the prints should remain a whole, nig' t in the water before the hyposulphate was suificiently removed 7 With regard to'the time necessary for each chemical color toproduce or give the rightshade to the print, practice must teach the person using them. All superfluous chemicals are soaked oil with fine tissue-paper or suitable absorbent, and in the operations above de scribed it is best that theyshould be performed in e room with a yellow light.

The following is the schedule of chemical colors hereinloefore alluded to:

A, flesh color Tenparts hyposulphate soda,

one hfindred parts distilled water, with gum-' arabic of sufiicient quantity to give it consistency.

- B, vcrmillion: Garminedissolved in concentrnted ammonia ,lgum-arabic of sufficient quan tity to give it consistency; or carmine and citric acid, with sufficient quantity'ot' gum-arabic; or pure potasl1, with carmine inammonia or other alkalies and acids; (alkalies produc: ing a violet, and acids a purple shade.)

G,-.yellow: Ten partsiodide potassium, one hundred parts distilled water, and 'suficient quiontity of gum-arabio; or, ten parts iodide potassium, five parts hyposulphate soda, five parts sulphate iron, one hundred parts distilled water, and sulficient quantity gum-arse I bio. With this yellow all varieties of shades can be produced, from a light blonde to the darkest, by simply varying the proportions accordingly or, ten parts salt of tin, five parts soda, one hundred Darts distilled water, and suficient quantity of gum-arable; or, ten parts acetate lead, one hundred parts distilled water and sufiicientquantityof gum-arabic in one vessel; and in another and separate bottle, two

v parts chromite of potassa, one hundred parts distilledwater, and snificient quantity of gumarabic. First use the former and then the latter. v

D, blonde: Fifteen parts iodide potassium, eight parts sulphate iron, one hundred parts distilled water, suflicient quantity of gum ara bio.

. E, brown: Ten parts hyposulphate soda, eight parts sulphate iron, one hundred parts distilled water, and sufiicieut quantity of gumarabic.

F, blue: Ten partsindigo, twenty-five parts sulphuric acid neutralized with ammonia, one hundred .parts distilled water, and sufiicient quantity of gum-arabic;

The above-enumerated colors are the principal ones, and if desired to produce others it is obvious that it is only necessary to vary the proportions. The proportions above given are simply illustrative and not intended to be regarded as fixed, it beingreadily manifestthat they must be somewhat varied in order to accommodate them to the intensity of the print, be it more or less.

Among the many advantages of the hereinabove-explained mode of manipulating, preparing and fixing colors upon photographic prints may be here mentioned, in conclusion, first, that the colors are fixed in such a manner as to preclude all possibility of ever being washed'ofi or injured by exposure to the sun or strong light, or by water, alcohol,spirits of turpentine, 860.; second, that colored prints can be thus produced at the same price, or nearly so, as common plain prints third, that every one can color photographic prints, whether acquainted with the art of coloringor not and, fourth, thatthe colors can be produced with cheapness, and at a much less cost than colors hitherto iii use.

Although I have particularly explained my improvement with reference to photographic prints, it is obvious that it can be applied also to altotypes, so called, or porcelain pictures, and to many if not all of the various styles of pictures produced in a similar manner to that employed in photography, and therefore I do notintend to limit myself to its adaptation to any oneparticular style or kind.

WhatI claim as new,- and desire to secure by Letters Patent, is-

1. Themanipulation of photographic prints, herein described, and for the purpose specified.

2. The preparation of colors andfixing them upon photographic prints, substantially in the manner described.

The above specification of my invention signed by me this 27th day of June, 1865.
