DAGUERREOTYPE-CASE.

Specification forming part of Letters Patent No. 9,611, dated March 8, 1853; Reissued February 9, 1869, No. 3,291.

To all whom it may concern:

Be it known that I, J. F. MASCI-IER, of the city and county of Philadelphia and State of Pennsylvania, have invented a new and useful Improvement in Daguerreotype- Cases, whereby the cases may be converted into stereoscopes; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the annexed drawings, making a part of this specification, in which Figure 1, is a perspective view of my improved daguerreotype case. Fig. 2, is a side elevation of ditto. Fig. 3, is a vertical section of ditto, the case being closed and bisected through its center.

Similar letters of reference indicate corresponding parts in each of the several figures.

The nature of my invent-ion consists in constructing a daguerreotype case with an adjustable flap or supplementary lid, said flap or lid being within the case and arranged as will behereafter described and having two ordinary lenses placed in it. The case contains two pictures or daguerreotypes. A daguerreotype being placed opposite each of the lenses in the flap or lid when the lid is properly adjusted. By this arrangement a perfect stereoscope is obtained and the daguerreotypes by binocular vision are apparently formed into a solid figure like life.

To enable others skilled in the art to make and use my invention, I will proceed to clescribe its construction and operation.

A, represents the bottom or back of the case which contains two daguerreotypes E, E, placed side by side as seen in Fig. 1.

B, is the top or lid connected as usual to the back A, by hinges (a). On the inner side of the top or lid B, there is attached by [FIRST PRINTED 1913.]

hinges (b) a flap or supplementary lid 0, said flap or lid when depressed fitting in a cavity in the top or lid B, as seen in Fig. 3. This flap or supplementary lid has two lenses D, D, placed in it each lens being directly opposite a daguerreotype, see Fig. 1. Now when the flap or supplementary lid 0, is raised in the position as seen in Fig. 1, and the back A, also elevated as shown a daguerreotype will be opposite each lens D, and a perfect stereoscope is formed and by looking through the lenses D, D, an eye being applied to each; the two daguerreotypes will appear as one; solid and life like.

The flap or supplementary lid C, is secured when raised to its proper position by a. small hook or catch (0) see Fig. 1.

' When it is designed to close the case, the hook or catch (0) is unfastened; the flap C, depressed within the lid B, and the lid B, and back A, pressed together as seen in Fig. 3, the whole forming a case as portable as the ordinary daguerreotype cases.

I do not claim the invention of a stereoscope, for that has been previously discovered. But

What I claim as new, and desire to secure by Letters Patent, is

Constructing a daguerreotype case with an adjustable flap or supplementary lid C, said flap or lid G, being within the case and having two ordinary lenses D, D, placed in it, by which, upon adjusting the flap or lid as shown, a stereoscope is formed of the case and the two daguerreotypes E, E, by binocular vision are apparently formed into a life like figure.
