METHOD AND MEANS OF PRODUCING MULTICOLORED PHOTOGRAPHS.

To all whom it may concern:

Be it known that I, Isn)oR Krrsnn, a citizen of the United States, residing at Philadelphia, in the .county of Philadelphia and State of Pennsylvania, have invented certain new and useful Improvements in Methods and Means of Producing Multicolored Photographs, of which the following is a specification. A

The object of this invention is to'provide an improved method and means of producing multi-colored photographs, whereby it is possible to make a negative photograph of agiven scene or object in different colors with the aid of one carrier or holder.

' Having made a negative, another object of the invention isto provide further steps "in the improved process, whereby it is possible from said negative to make as many positive prints as may be required without imit.

A still further object is to provide an improved product, which product may be used with but slight. alteration in'ipreference to the commonly known opaque print of a blackand-white negative, or as a transparency-for A .limtern-slides and the like.

More than one method of color-photography that has been developed thus far comprises the formation of a set of monochrome transparencies, each of a fundamental color and embodying a positive photograph of that part of a given object or scene having "a 00 until every ob ect upon "each transparency matches up as nearly as possible with the cies are t en su rimposed one upon another corresponding objects upon the other transparencies, or, in other'words, so that each 40 set of transparencies registers perfectly or with the least possible displacement.

However, all those who have made photo-\ graphs by certain of the processes which are 'carried'out alongthe line -mentioned have experienced an almost insurmountable obstacle in their inability to exactly register the plurality of transparencies, for, while the one oftenin yellow is usually ratherwell defined, that probably in red is much less so, and the one generally tinted blue is in' most instance so vaguely definedas to make it almost an absolute impossibility to find the exact position which it should bear with encies.

Bearing these objects in'mi-nd, the invenich was origtion' comprises details of construction and operation hereinafter clearly described in the following spccificati0n, whenread in conjunction with the accompanying draw-i ings, in which Figure 1' is atop'plan view of the principal elements of a camera such as.

8 is a similar view showing the positive transparency-unit mounted as an ordinary opaque print. I I

Referring to the drawings, a camera is shown comprising a base 1, upon which is mounted the usual frame 2, from the forward open side of which projects the usual bellows 3, provlded upon its outermost restricted portion with the usual lens-holder or casing 4, said last-named casing being carried adjustably vertically by a support 5, extending upwardly from a slide 6 adapted to reciprocate for the longitudinal extension of said bellows upon a track 7. The

essential difference of this camera from those commonly in use res des in the factv that the frame 2 is provided upon the rear ,thereof with a substantially rectangular box or chamber 8, having the length of its side walls 99 substantially equal to the width of the device across the real-most wall 10. v

The said inclosure 8 may, if desired, be

. separable from the remainder of the camera in order that the former may be readily dismounted from the latter and carried to a dark room, where it is obviously most conveniently loaded with a sensitive negative transparency-unit, a .dark slide or trap 8 being provided to close said box when thus dismounted. As shown schematically in Fig. 1, the negative-unit comprises a central section 11 positioned parallel with re spect to the wall 10, a forwardly laterally positioned section12 parallel with respect to the wall 9, and asecond and similar forwardly extending laterally positioned section 13 positioned parallel with respect to the wall 9'.

Primarily, it is to be noted that in general the present process provides for the consecutive exposure of each of. the lateral and central sections of the negativeunit to the rays of light from the object to be photographed as said rays pass through the lens-holder 4.

T 0 this end, it is not of vital importance what order is employed in the exposure of these various negative-unit sections :Thus, an exposure upon the central section may be made with .the apparatus positioned exactly as shown in Fig. 1, after which the negative section 12 may be moved, by suitable means connected to the knurled wheel 12", about the center 12 into'the dot-and-dash position parallel with and abutting against the section 11. An exposure being made upon the section 12 in this position, said section is removed, by revolving the said wheel inthe reverse direction, to its position adjacent to the said wall 9 of the device. and the negative section 13 is shifted about the center of 13, bymeans connected to the knurled wheel I 13", into the dot-and-dash position just previously occupied by the section 12, in which position a third exposure is made, this time upon the section 13.

Preferable in practice and possibly necessitating the least number of movements during the exposure of a complete negative-unit, the box 8 is loaded with either of the sections 12 or 13 inthe dot-and-dash position, in which position an exposure thereof is I made, after which the exposed end sectionof the negative-unit is shifted to one side, an

exposure made of the central section of the slightly smaller than the corresponding number ofv pan-chromatically sensitized carrier sections 22?, 22', and 22 mounted upon said sheet and secured thereto centrally with relation to the respective apertures 21. The mat 20 is furthermore provided, centrally positioned. between the neighboring apertures 21, wit-h transversely extending elongated slots 23, from the opposite ends of which to the neighboring edges of said sheet extend score-marks 2t fora purpose hereinafter described. i.

yEach of the carrier sections 22 22 and 22 is coated upon one face wit-ha panchromatic emulsion. The 'carrier sections 22. a-nd'22 are furthermore provided upon A mat 20-of non-elastic material is the surface thus sensitized with opaque coatings as indicated, while upon their opposite faces they are respectively coated with green and blue coloring for the purpose of forming screens of those partlcular colors.

The intermediate carrier section 22" has a colorscreen of red upon the surface of the emulsion and is without a coating of any sort upon its opposite surface. These respective color-screens and opaque coats are readily removable after exposure of. the units to light, either before or during the process of developing andfixing of the emulsion layers carried by said units,

The negative unitthus formed is inserted into the box portion 8 of the camera, as.

shown in Fig. 1, and three closely consecutive exposures made by any of the usual.

methodsof intermittently opening and clos-- ing the camera orifice in the lens-casing 4 and as hereinbefore described. With the negative-unit. preferably in place; as described, light rays, permitted to eiiter the camera through the usual lens for a short period of time, pass through the colorscreen and carrier of, and act upon the emulsion upon, the opposite side of the carrier section 22* in the dot-and-dash position, but cannot contlnue past the opaque coating and afiect the emulsion upon the carrier carrier section is shifted or pivotably swung out of the dot-and-dash posit-ion, immediately after which light rays are permitted to section 22 after which this first-exposed case passing through the color-screen car-.

ried thereby and acting upon the emulsion surface of the saidcarrier section. Similarly, after the carrier section 22"is thus exposed, carrier section 22 is shifted into the dot-and-dash position and exposed, light rays passing through the color-screen and transparent carrier before acting upon the emulsion carried thereby and being stopped by the opaque coating from continuing onward and'afiecting the emulsion of the carrier section 22'.

\ pose the chemicals comprising the emulsion The negative thus exposed either has the color-screens and opaque coatlngs first dissolved or otherwise removed therefrom as before mentioned, after which the emulsion coatings are developedand fixed in the usual manner and permitted to dry. It should be remembered that thus far, and in fact continuously hereafter, the negative-unit comprising the mat'20 and transparent carrier section'attached thereto are at no time disunited, although they may be shifted in angular position with respect to one another by virtue of their relative' pivotal connections.

To print from the negative thus produced, a frame is provided comprising abase 30, from which extend-upwardly, spaced, parallel bars 31, in length, thickness and distance between centers being exactly equal to the slots 23 ofthenegative-mat 20. Upon this base is placed a transparent carrier 32, par-' ticularly illustrated in Figs 5 and 6, the

same being provided with spaced parallel elongated slots 33 "adapted to receive the bars 31 of the printing frame, while in alinement with said slots are. score-marks 34, upon which lines the carr ier isllater to be folded, said carrier also being providedv upon its upper surface "with a coating of chromated gelatin 35. Upon this positive,

sensitized-carrier is placed face downward the previously exposed negativemnit hereinbefore described and as clearly shown'in Fig. 6.

With the negative and chromated blankv 1n the positions thus shown, the combination is exposed to lightso that rays of the same pass through the negative and decomnpon the chromated carrier. Removin both of these elements from the printing rame,

series of spaced. apertures, incombination 120 the'chromated carrier,printed on by means of the well-known process, is found to comprise three distinct photographic impressions which, are complementary as to light and dark portions to those carried by the negative-mat. The printed positive is then treated in the usual manner to remove the unaffected gelatin. j V

It is now possible to tint or stain the three respective photographic impressions of the positive by means of colors which are re- .product illustrated by Fig., 8 is the equivalent of and closely resembles the usual pho- .through which the original negatives-have .105

' Patent of the United States is positive section 32 corresponding 'with "(green) negative carrier section 22 is stained red, the central positive section corresponding with (red) negativ'ecarrier sect'ion 22 is stained blue, and the OSltlVG sec- -tion 32 corresponding with lue) negative carrier section 22 is stained yellow, the coloring in each of these instances adhering only'to those parts of the sensitized positive surface on which the emulsion has been affected by'light, and also to the extentto which said emulsion has been thus acted upon. I e p The resulting positive then simply folded upon the score-lines 34, so that the result as illustrated by the cross-section in Fig. 7 comprises a photograph adapted to be mounted on a suitable base such as a matv 37, which in reality maybe one of-the stiff papers or boards used in mountin photographic prints. Said mat has a sur ace possessinghigh reflective powers, so that the tographic print upon white paper, except for the fact that the reproduction possesses.

natural colors of the original object. It is obvious that instead of printingon gelatin from the negative directly, a transparent positive may first be made from-said negative, and the chromated gelatin prints may then be produced'with the aid of such .pos1- tive. In that case, it is suggested .to tint the different sections of. the gelatin prints with, colors substantially the same as the filters been taken, and ,the complete photograph maybe mounted on a suitable transparent. materialfor lantern-slides or to be viewed as transparencies.
