Specification forming part of LettcrsPatent No. 81,277, dated August 18, 1868.

To all whom it 11mg/ con-oem:

ne a known niet LA. s. nner, of Huntington, in the county of lluntington and State ot' Indiana, have invented a new and Improved Apparatus forPrinting and Grouping Photographs; and I do hereby declare that the following is a full, clear, and exact description thereof, which will enable others skilled in the art to make and use the same, reference being had to the accompanying drawings, forming part of this speciiication.

-Figure l is a bottom .view ot' the upper fixed portion or cover from a section through the line y y, Fig. 2', which latter is a vertical central section through the line .fv Fig. 1.

The object of this invention is, its name imports, for the purpose ot' printing photographs, whereby the same are grouped and printed in a rapid and convenient manner.

. case, and the other hinged to the ease by means of any suitable hinged device, h, whereby the parts maybe separated broadly from Qlhe case is preferably of sheet niet-al, and contains a roller, B, provided with a crank, C. This roller is for the purpose of rolling up the sen sitized paper on which the photographs are printed by the suns rays acting through the lights of a negative plate placed in the leaf E, which is above the paper. rlhis portion E is made with a large rectangular opening, 1 2 3 4, which is covered by-a slider working with easy contact on a broad dovetailed groove made in the upper face of the said leaf. The motion of this slider is parallel with the cylinder, or at right angles to the movement of the paper when being Wound on the roller B.

The slider is formed with an opening, 1n, to admit the suns rays upon the negative plate e just beneath it. I .The negative plate is held by a clamp, f, the shank of which passes through the slot g in the slider, the said shank being threaded, and provided with a burr, i. This clamp is adjustable to the extent ofthe slot to' clamp different-sized negative plates.

the shank, which stein passes outward to the end ofthe slider, and terminates in a handle, l, of any suitable form.

-When card-photographs, or photographs of small size, are to be printed, a condensing-r lens, of the proper focal distance, may be employed in the manner Well known to those skilled in the art of lihotographiu g.

'a is a diaphragm placed beneath the opening m of the slider, and attached thereto by doivel-pins, or other means which will permit its easy removal when not required.

rlhe diaphragm is made with a central circular opening, a, for the purpose of excluding the suns rays from a portieri of the negative, allowing only a part, as a persons head, to be printed. This diaphragm may be used or removed at will; but ivhen removed the light will be admitted upon the negative tlnough the full opening m, and the whole of the negative printed. A

To use my invention, the sensitive or photographic paper is placed between the leaves, and beneath the nega-tive plate, the front edge of the paper being attached to the roller B.

The apparatus is placed in the sunlight,

with the leaf E uppermost. rlhe grouping of` the heads or other pictiu'es is accomplished by moving the slider to obtain a lateral arrangement of the impression, the longitudinal arrangement being obtained by winding up the paper on the roller.

The case is slotted for the passage of the paper through it, which latter' is shown in both figures. Clasp-hooks d d serve to hold the leaves together. '.lhe cylinder' is provided with a cap, H, by means ot' Which the roller is withdrawn, as the crank G fits within 'a square socket in the same. The case excludes the light from acting upon the paper.

I claim as new and desire to secure by Letters Patent- The leaves D E, slider G, case A, roller B, and suitable clanipsj f', all substantially as described, when contributing to form an app aratns for printing photographic pictiues, all as set forth.
