MULTICOLOR STEREOSCOPIC DEVICE.

Specification of Letters Patent.-

Patented Oct. 15, 1918.

Application filed December 13, 1915. Serial No. 66,468.

To all whom it may concern:

Be it known that we, ALFRED ALLEN, JOHN J. MURPHY, and HARRY A. WILLARD, citizens of the United States of America, residing-atToledo, Lucas county, Ohio, have invented new and useful Multicolor Stereoscopic Devices, of which the following is a specification.

This invention relates to reproducing subjects as originally appearing.

This invention has utility when incorporated in views, and apparatus for facilitating the inspection thereof, to disclose the third dimension in the different colors thereof as a commercial proposition for compact handling and shipment in little space at a minimum of expense for production, with simplicity for manipulation in use owing to absence of involved or technical features.

Referring to the drawings:

Figure l is a perspective view of an embodiment of the invention, with parts broken away, shown in set up assembled position for use;

Fig. 2 is a front elevation of a stereoscopic View comprising color value elements of dissimilar colors in fields of such colors, as adapted for use in the device of Fig. 1;

Fig. 3 is a perspective view in partially collapsed position of the first tube of the stereoscope device of Fig. 1;

Fig. his a perspective View in partially collapsed position of the second tube of the stereoscope of Fig. 1;

Fig. 5- is a perspective View in partially collapsed position of the third tube of the stereoscope of Fig. 1; and

Fig. 6 is a side elevation of the pair of stereoscopic lenses for mounting in the tube of Fig. 5.

The simplicity of thedevice is such that the elements thereof may be forwarded in knocked-down condition to the trade or users thereby minimizing space, with the device of light weight construction amply substantial .to withstand normal usage in practise.

The stereoscope comprises the main member 1, being a tube of rectangular cross section having the end closure 2 slightly offset by the coacting flanges 3,4, at the sides and .5 at the base to form a view receiving pocket when brought up to alined osition as to the tube 1, and. so firmly hel by the locking ting off all light rays to a view placed against the end closure 2. v

The top portion has the window or cutback portion 8 approximately balancingthe light ray illumination of a view as tothe elements thereof, as inspected through the tube 1. This brings about a coiiperating function in synthesizing or 'combining the value colors for accurate and effectiveresults.

The element 9 (Fig. 6) may have openings therein surrounded by the'bent out wings 10 to whiclrmay be attached by an adhesive the respective stereoscopic lens elements 11. This lens carrier 9 may be disposed to have the lenses 11 register with the openings 12 in the collapsible tube 13. Alining with the openings 12 are the openings 14 which in the set-up position will have the wings 15 therefrom swung back into the tube and lockedin such partition forming position by the tongue 16 engaging the recess 17. The terminal flanges 18, 19, of the tube 13, are bent inward to assist in the frictional holding of this tube 13 in tube 20 and also look carrier 9 in set up position. The tube 20 is thus held against collapse and is adjustable in the tube 1 for ready focusing of the lenses 11 as to the view in the seat 2.

This View may comprise the element 20 having'the color field 21, say of red, with the outline 22 in said field valued in red. The corresponding stereoscopic element or view 23, from a spaced origin for stereoscopic effectiveness, may have its field 24 of color dissimilar to the color 21, say green, with the outline or image 25 valued in such color.

In the operation to attain the articles of manufacture hereunder, a stereoscopic view ma pla t e, say of the Lumiere type. Owing to the different speed actions of the complementary or differing colors, this simultaneous be taken with any pan-chromatic the color green, developed for proper strength relatively to the outline from the color red. These two separately produced outlines from the basic plate may be printed in adjacent positions for the regular stereoscopic view but each of these outlines 1n the projection of this stereoscoplc v 1ew, as an integral article of manufacture, is dlsposed in a field of its color.

'In the multiplication of these devices, they may beconveniently produced as half tones, at a single impression completing each view, by using say the red ink for the field and the outline, the strength of the field differing so there is the outline contrast. While in other operations say as in printing from negatives, the field may be the stock color or the stock may be colored after the outline is developed thereon to produce a unitary article of manufacture. The result ing operative device or element is, whether or not the outline is of'black or of a color, a color value outline in a field of such color. In practice, it is found the two colors mentioned are serviceable over a wide range for accurate reproduction of multi-color work with different shades and colorings be- ,vond the two in the viewas a result of inspection through the stereoscope herein, for there is a synthesizing or re-combining approaching original appearance in all the original tints, shades and colors of the spectrum. The selection of the two field colors and corresponding values simplifies this reproduction, not only for photographic but for printing purposes. a

In some instances of special colored objects, it may be desirable to specially adapt the contrast colors for the v1ew fields and the color valued outlines thereon. The instance herein of a strong color from one end of the normalcolor spectrum, and a second strong color from the other region of the spectrum, due tothe color spacing, shows up in a measure of practical commerclal worth, when combined for viewing in the stereoscope combination. In producing the views, the color 21 .may be the color of the stock used or a coating on the stock, and outline 22 may be in black ink thereon over or under a coating on the stock. Accordin ly, the single black outlines on the dissimilar for said outlines.

fields or backgrounds may at one printing impression produce a view of spectrum disclosing effectiveness. This result from black ink is due to the color valued black 2. A third dimension and color disclosing I view comprising two dis-similar color value outlmes and corresponding fields of color 3. A stereoscopic view including spaced origin color valued outlines, each having integral therewith a color valued. field of such color. v

4:. A stereoscopic opaque picture comprising right and left hand views having com. plementary color. values in fields of such color.

5. In a device for disclosing views in color by reflected light, the combination with an opaque base of color outlines-thereon in fields of complementary colors in union with said base.

6 In a device for disclosing more than two colors by reflected light in views, the combination with an opaque base of complementary colored fields thereon, each of sa d fields embodying an outline therein, sa1d colored fields and outline being fixed with the base.

7. The combination in a picture disclosing field. I

8. The combination in a-picture disclosing dev ce, of a base providing a colored field fixed therewith and in said field an outline valued in the color of said field.

In witness whereof we afiix our signatures.

ALFRED ALLE JOHN J. MURPHY; HARRY A. WILLARD.
