APPARATUS FOR WASHING PHOTOGRA'P'HIC PLATES.-

SPECIFICATION orming part of Letters Patent No. 354.344, dated December 14, 1886. Application filed June 8, i886. Serial No. 204,460. (No model.)

To all whom it may concern.-

Be it known that I, HENRY CLAY PRICE, of New York, in the county of New" York and State of New York, have invented a certain vill Manufacturing Company as my assignee.v

That apparatus consisted, essentially,- of a vessel provided with racks adapted to.hold photographic plates at the'edges only in an upright position, and a perforated false bottom sustaining the lower edges of the plates, said vessel having pipes for conveying water to it and away from it. One or more of the racks had a connection with the vessel, which per mitted of its adjustment into different positions in order that the apparatus might be used for different-sized photographic plates.

My present improvement consists in the combination, in an apparatus for washing photographic plates, of a vessel adapted to contain water, pipes for conveying water to and away from the vessel, and a frame adapted to be inserted into and removed from the vessel, and having a perforated bottom which, when the frame is in place, will be elevated somewhat above the bottom, a space being left between the sides and ends of the frame and the bottom of the frame, and racks -for. holding photographic plates to be washed. Preferably one or bothof the racks will be capable of adjustment, so that photographic plates of different sizes may be held in the frame. The frame maybe lifted outof the vessel whenever it is desirable to remove plates from the water in the vessel.

In the accompanying drawings, Figure 1 is i a plan of an apparatusembodying my im- .provement.

' plates are to be supported, said Fig. 2 isa vertical longitudinal section of the same. Fig. 3 is a perspective view of the frame in which the photographic frame being removed from the vessel. i 1 Similar letters of reference designate corresponding parts in all the figures.

gular form, and made preferably of zinc or analogous metal. It is provided with a cover, A, which is hinged in place at one side. As here shown, the cover is provided with a rim which, when the cover is closed, will lap over the upper edge of the body of the vessel.

B designates apipe leading to the lower part of the vessel for conductinga stream of water thereto, and O designates a pipe extending from the upper part of. the vessel, and

serving to convey away the water after it has The pipe B-may passed through the vessel. be connected to any suitable service-pipe and the pipe O to any waste-water or sewer pipe.

D designates a frame having a perforated bottom plate, (1', having the edges bent downward, so as to'form supports (2 From the bottom d, near its corners, uprights (1 which may be made of brass or other metal wire, extend. The upper ends of these uprights are connected by intervening portions. of wire, forming handles by which the frame may be lifted. Side pieces, (1, and end pieces, (2 are connected to the uprights d These side pieces and end pieces may be made of a continuous piece of zinc or analogous metal. 'They are elevated above thebottom (1', so that a space is left between the sides and ends and the bottom.

The frame D is of such size that it will fit snugly within the vessel A ,'the handles being near the top of the vessel when the frame is in place. The bottom of the frame will be abovethe pipe B. Watercan circulate upwardly within the frame from the pipe B. The frame is provided with racksE F, for holding the photographic plates to be washed. The

rack E is made by attaching a corrugated strip of zinc or analogous metal to the inner side of one of the end pieces (I? of the frame D. The rack F is made of a plain strip of metal, having attached to one side'a corrugated strip of The racks E F may, however, be dif-. ferently constructed," but must have opposite grooves, b. l

, The side pieces dof the frame D are proyided with slideways g, into which the rack F may be.- inserted, so that it and the rack E will be in proper relative positions to support photographic plates of different sizes to be washed. While the photographic plates are held in the racks they will 'rest upon the per- I forated bottom (1 of the frame D. The grooves b of the raekswill hold the photographic plates out of contact with one another.

The frame D is not fastened within the vessel A; consequently it may be removed from the latter and replaced at pleasure.

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

In an apparatus for washing photographic plates, the combination of a vessel, pipes for conveying water to and from the vessel, and. a frame fitted within the vessel and consisting of a bottom elevated above the bottom of the vessel'and having a space between its bottom and its sides and ends, and racks for holding photographic plates while resting upon the bottom.
