lb ctZZ whont it may concern:

Be it known that I, SAMUEL SALOMAN, a citizen of the United States, and a resident of the city of New York, borough of Bronx, in the county and State of New York, have in vented a new and Improved Photographic-Plate lVashing and Fixing Apparatus, of which the following is afull,clear, and exact description.

The purpose of this invention is to provide a novel device for both fixing and washing photographic plates, by which I am enabled with a single apparatus to perform either one of these operations.

This specification is the disclosure of one :form of the invention, while the claim defines the actual scope thereof.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar characters ofreference indicate corresponding parts in all the views.

Figure 1 is a perspective view of the invention. Fig. 2 is a longitudinal section, and Fig. 3 is a cross-section on the line 3 3 of Fig. 1.

The apparatus comprises a rectangular case or reservoir, Ct, which may, if desired, be fitted with a sliding top or lid 1). The ends of the reservoir to are provided on their inner surfaces with thickened portions a, formed with vertical grooves a therein. Photographic plates maybe fitted in these grooves, in which case the plates will be of a length approximately equal to the interior dimensions of the reservoir a. For limiting the downward movement of the plates ledges a are formed at the lower ends of the grooves a in the thickened portions a, so that the plates will engage these ledges and be sustained thereon. The side walls of the reservoir (1 are formed with horizontally and longitudinally disposed grooves c, which communicate with downward extensions c, arranged in pairs, the members of which are opposite each other. There are preferably two pairs of these downwardextensions 0; but this is not essential, as it will be understood the number may be increased or diminished at will. A partition (1 is provided and has a width equal to that of the inner width of the reservoir a, the side edges of the partition at its upper portion being formed with ears d, adapted to slide in the grooves cand capable of moving also with the partition into the extension c. It is clear that by this arrangement the partition d may be placed with its ears cl in either of the two pairs of extensions 0 of the grooves c, and thereby the position of the partition may be adjusted. The partition d is formed with vertically-disposed grooves (1 adapted to receive the edges of the photographic plates, and these grooves terminate at their lower ends in a ledge d for limiting the downward movement of the plates. By means of the adjustable partition d plates of various sizes may be fitted in the reservoir.

The reservoir is provided with liquid inlet and outlet pipes c and 6, respectively provided with closure-capsfand f. \Vhen fixing the plates, the capsf and f willbe placed in the position shown in the drawings and the reservoir a filled with the solution, so that the plates may be properly subjected thereto, and in washing the plates the caps f and f may be removed, so that a continuous circulation of water may be maintained through the apparatus. In this connection it is pointed out that the partition ddoes not interfere with the circulation, although it may baffle the same, thus causing the water effectively to act on the plate or plates which may be in the reservoir.

Having thus described my invention, I claim as new and desire to secure by Letters Patent- The combination of the receptacle having at one end vertical grooves terminating above the bottom to form stops, and in its sides parallel longitudinal grooves immediately above the level of the upper ends of said vertical grooves, and registering vertical grooves extending downward in the sides of the receptacle from said longitudinal grooves, and a partition having ears arranged to slide lengthwise in said side grooves and into the downward vertical grooves, said partition having vertical grooves corresponding to those in the end of the receptacle, and a ledge extending horizontally across the partition below the lower ends of said grooves.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

SAMUEL SALOMAN.
