Treating Photographic Paper. No. 105,233. Patented July 12. 18 707- LUTHERV. MOULTON, OF MUSKEGON, MICHIGAN.

Letters Patent No. 105,233, dated July 12, 1870.

FRAME I'OR SENSITIZING P HCTOG-RAPHIC PAPER.

The Schedule referred to in these Letters Patent and making'part of the same To whom it may concern Be it known that I, LUTHER MOULTON, of Muskegon, in the county of Muskegon and State of Michigan, have invented a new and useful Improvement in Method of Applying Solutions to Photographic Paper; and I do declare that the following is a true and accurate description thereof; reference being had to the accompanying drawing and to the letters of reference marked thereon, and being a part of this specification, in 'which Figure l is a perspective view of my apparatus.

Figure 2, a vertical section, showing the apparatus in detached sections.

Like letters refer to like parts in each figure.

v The nature of this invention relates to an improvement in the method of applying solutions to photographic paper, so that large sheets of. paper may be operated upon and worked, without the employment of large and expensive trays; that will require a less quantity of solution; that will avoid the necessity of handling'the paper during the process, and the consequent danger of producing stains.

The invention consists in placing the sheet of paper to be operated upon in a frame, so constrncted as to bindthe edges of the paper on all sides. The frame then becomes the sides of a tray, with the sheet of paper for the bottom, upon which a proper quantity of solution maybe poured, when, by imparting a rock- 'ing motion to the frame, the solution is caused to flow evenly over the paper, and the remaining solution can then be poured off at a proper lip formed in one corner of the frame.

It further consists in the peculiar construction of a frame for the purpose, as-more fully hereinafter specitied and shown.

In the accompanying drawing- A represents a frame, rectangular in form, made in two sections, B O.

The upper edge of the section 0 is provided with a tongue, (1, which, when the two sections are in pface, fits closely in a corresponding groove, 1 in the lower edge of the section B, or a tight joint may be made between the sections in any other convenient manner.

The sheet of paper to be operated upon should be a little larger than the superficial area of the frame, and should be laid upon the lower section thereof, so that it will cover the tongue. Then the upper section should be pressed down until the groove engages with the tongue, and makes a water-tight box or tray.

After the paper has been treated as hereinbefore described, the remainder of the solution may be poured off at the lip 0, formed for the purpose, at one of the upper corners of the section B. The paper may then be left to dry in the frame, and, when ready for use, will be found quite smooth, instead of being wrinkled, as when prepared in the ordinary way.

\Vhat I claim as my invention, and desire to secure by Letters Patent, is-

The frame A, made in two sections 13 G, as

herein specified, and employed for the purpose of applying solutions to photographic paper.

LUTHER V. MOULTON.
