J. P. BROCKWAY PROCESS OF REPRODUCING IMAGES 0N METALLIC SURFACES Filed Feb. 28, 1929 75 CHLUR/NE GAS SUPPLY I is-4.
SAN DIEGO, CALIFORNIA PROCESS OF REPRODUCING IMAGES ON METALLIC SURFACES Application filed February 28, 1929. Serial No. 343,576.
My invention relates to a process of reproducing images on metallic surfaces, more particularly copper surfaces, and the objects of my invention are: First, to
provide a new and novel process of reproducing images; Second, to provide a new and novel process of reproducing images on metallic surfaces; Third, to provide a new and novel process of reproducing images on metallic polished surfaces; Fourth, to provide a new and novel process of preparing film or negatives for reproducing from said film or negative on metallic surfaces; Fifth, to provide anew and novel process of fixing the image on said metallic surface, and Sixth, to provide a new and novel process of this class which is very simple, efiicient and economical of operation, effective, and which produces surfaces with images which are very durable.
With these and other objects in view as will appear hereinafter, my invention consists of the certain novel process as will be hereinafter described in detail and particularly set forth in the appended claims, reference being had to the accompanying drawing which form a part of this application in which:
Figure 1 is a diagrammatic view of a chlo rine gas supply container; Fig. 2 is a sectional view of a printing frame illustrating the facilities used in my process; Fig. 3 is a diagrammatic view of my electrical fixing bath apparatus; and Fig. 4 is an edge View of the finished metal plate with the lacquer coating.
My process consists in taking an unsensitized photographic film of convenient size, a film 1 whose emulsion contains no salts of silver or other sensitizing chemical, and immersing said film in dry chlorine gas for an hour or more as shown in Fig. 1 of the drawing; then placing this film on any highly polished metallic surface, such as iron, steel,
Monel metal, brass or copper, as designated 45 2 in Fig. 2 of the drawing preferably copper;
then placing on this surface a negative 3 with a picture or images; these may be bound together in a photographic printing frame 4,
or supported in their relation to each other 50 otherwise; and then exposing the same to sunlight 5, or other similar light 5. The light will cause the adsorbed chlorine gas in the film 1 to become active and will print out the picture design or image contained in the negative on the metallic surface as shown in Fig. 3. After the picture or image has been printed out or made on the metallic surface it may be made permanent or fixed by electricity as follows: i
The object 2 with the picture or image is immersed in a bath of distilled water, 1500 cubic centimeters, nickel ammonium sulphate, 5 grams, sodium chromate, 5 grams, and ammonium bisulphate,5 grams, which will form a bath. A. plate forming an anode is placed in the bath and said treated surface is used as a cathode and subjected to a current of electricity of 10 or more volts D. C. for a second or more of time, which will render the picture permanent, all as shown in Fig. 3. The treated surface is immediately removed from the bath and thoroughly Washed in running water and dried; then said surface is covered with a fine, transparent lacquer 6 as shown in Fig. 4 to prevent marring or scraping of said surface.
In some cases, if desired, the film may be omitted and the negative may be subjected to or immersed in dry chlorine gas for an hour or more and the negative placed next to the 30 highly polished metal surface and exposed to the light, as hereinbefore described. 4
In the place of a photographic film treated in the manner above described, any other transparent sheet, capable of absorbing the gas and remaining inert thereto, may be employed, as for example, celluloid, or transparent paper. I
When desired to reproduce an enlarged image from a negative the image is thrown onto the absorbent film placed over the metallic surface, by means of a conventional enlarging apparatus. The negative is of course not in contact with the gas treated film in this case.
Though I have described a particular process of reproducing images on metallic surfaces, I do not wish to be limited to this particular process, but desire to include in the scope of my invention the process substan- 100 tially as set forth in the appended claims.
