PHOTOGRAPHERS IDRPPING- .AND DRYIN'GRACKl The Schedule referred to in these Letters Patent and making part pf the same To all whom it Amay concern.-

Be it known that I, VICTOR M. Gnrswom), of

g Peekskill, in the county ot' \Vestchester, and State cheap, and etiicient device 0r apparatus for holding or supporting photographic plates,'wliile the surplus ot any liquid or tluid -with which they have been coated, floated, or covered, drains or drips from them, and allows them, if desired, to become dry. A second object accomplished byiny invention is the saving of the said surplus which drips from the plates, and preventing it from soilingthe table or other support on which the rack or plate is placed.

My said invention consists- A First, of a vertical series of supports or hooks, arranged in pairs, upon, between, or into which one of' the corners ofthe plate is inserted and held, withoutthe face ofthe plate coming in contact with said supports or other portions of the rack, while the surplus iluid drips from it. These supports may be formed by inserting pins, hooks, or pieces ot' sheet-metal at a proper angle to hold the plates, in a backing, frame,

or plate, of wood or other material. A central groove or t-rough may be formed in the said backing to receive the drippings, and conduct them to a proper receptacle. But l prct'er to make the rack wholly of sheet-metal, properly japanned, varnished, or otherwise coated wit-h some suitable substance, which will not be acted on, nor cause chemical action in the chemicals used upon the plates.

Second, in the combination of the said supports, ar-l ranged as described, anda central trough or groove, running vertically between the individual supports oi each pair, so 'as to catch the drippings from all the plates in the rack, and conduct the same to a bottle or other receptacle placed at its lower end.

Third, in the combination, with the backing or frame of the said rack, of a pair ot' legs or braces, which hold -the said rack at the proper inclination when itis lumg upon a wall or other support.

In the accompanying drawings- Figure l is a side elevation ot' a rack embodying my invention.

Figure 2 is a front elevation of the same.

Figure 3 is a horizontal section ofthe same, on the. line a: a', tig. 2.

This rack is made of a single piece of sheet-metal, cutout in the proper form, and a longitudinal groove or trough, A, stamped or pressed into it, leaving the remainder ofthe plate ilat.

The edges are divided, by horizontal incisions, into teeth or blocks, and the outer lower corner of each of these teeth or blocks is bent upward toward the diagonally opposite corner of' the same block, tlms forming oblique hooks, or enclosed ledges, or troughs B, into and between which the corner of the plate is inserted.

A small trough or groove is thus left at a, between the edge of the plate and thc inner angle of the support B, through which the fluid may readily escape into the trough A.

The lower corner of each plate, from which the fluid drips, is thus brought immediately over the trough A, and the fluid drops into the said trough, and is conducted to the spout C, whence it is discharged.

Legs or braces D are cut out from the body of tho metahand bent backward, so as to rest against the wall, when the -rack is hung up, thus holding it at the proper angle to insure the dropping of thetluid into the trough and its proper discharge.

The legs D also keep the rack from swinging around, so as to allow the plates to fall out.

E is a hole in the upper part ot' the rack, by means of which it may be hung upon a nail or pin.

The rack, formed as above described, is japanned, varnisbed, or otherwise coated with some substance which willynot be acted upon by the tluids which drip from the plates.

By its use -the solutions or other fluids which drip from the plates are almost entirely saved, as -by the nearly perpcmlicular posit-ion ot' the trough A, the said tlnids are at once returned into the bottle, t-hus preventing their becoming clogged in `the trough, and their purity destroyed b v evaporation, accumulation of dust, and chemical action excited by the trough itself.

'.lhc operator can drain or dry a dozen or moreot' plates in about the time usually required for draining or drying one or two, and the cost ot' the rack is very much less than ot' any other device now in use for the same purpose.

Having thus fully described my invention,

I claim- 1. The supports B B, arranged in pairs, in a series, and set upon, or into, or secured to a suitable' frame or backing, substantially as and for the purpose set forth.

2. ,lhe combination, with the supports .l B, of the trough A, substantially as seti'orth.

o. The combination, with the body of the rack, of

the legs or braces D, substantially as and i'or the pur.

pose speciiied.

4.. The rack described, formed ot one piece ot sheet-- metal, substantially as and for the purpose set fort-h.
