vSPECIFICATION forming part of Letters Patent No. 362,782, dated May l0, 1887.

n Application iled January 26, 1887. Serial No. 225,530. (No model.)

To all whom t may concern:

Be it known that I, CHARLES It. QUIG LEY, of Boston, in the county of Suffolk, State of Massachusetts, haveinvented a certain new and useful Iniproveinentin Photographic Developing-Cabinets, of which the following is a description sufficiently full, clear, and exact to enable any person skilled in the art or science to Which said invention appertains to make and use the saine, reference being had to the accompanying drawings, forming part of this specification, in which- Figure 1 is a front elevation of my improved cabinet, one of the guards being represented as broken away; Fig. 2, a rear elevation of the saine with the guards detached; Fig. 3, a side elevation of the same; Fig. 4, a top plan view with the cover in position; Fig. 5, a like View, the cover being represented as removed; Fig. 6, a vertical section taken on the line x x in Fig. 5; Fig. 7, a like view taken on line y y in Fig. 5; Fig. 8, alike View taken on line zz in Fig. 5; Fig. 9, a front elevation of a plate-rack removed, and Fig. l0 a side elevation of the same.

Like letters of reference indicate corresponding parts in the different figures of the drawings.

My improvement relates more especially to apparatus for developing the dry-plates used in photography, being designed to take the place of the ordinary dark-room#7 and it consists in a novel construction and arrangement of parts, as hereinafter more fully set forth and claimed, the object being to produce a more simple and effective device of this character than is now in ordinary use.

The nature and operation of the improvement will be readily understood by all /conversant with such matters from the following explanation:

In the drawings, A represents theY body of the cabinet, and B B the guards. The body consists of a rectangular-shaped box, preferably about two feet and ten inches in height, one foot and three inches wide, and one foot and eight inches deep, and is provided with a hinged cover,-K, in which are set .two lights of glass, k, (see Fig. 4,) the upper or outer door, M, in which is set orange and ruby col` `ored glass D, Substantially the same as in the cover K, the outer pane being ruby and the inner orange colored. In the back side of the cabinet is a large pane of orange-colored glass, N, (see Fig. 2,) on either side of which are disposed two or more screw-eyes, d, adapted to lreceive the bent ends of a bar, l?,which supports a shelf (not shown) for holding a lamp, the lamp being used when it is desired to eniploy the cabinet at night.

In either side of the cabinet and near the front there is a rectangular-shaped opening, O, and around each of these openings is secured a funnel-shaped guard, B. (SeeFig. l.) These guards are largest at their inner ends, being oblong in cross-section, and are preferably composed of some iiexible material, such as rubber cloth. They are also made in such a manner that their lower edges, f, are some- What longer than their upper edges, m, to enable the arm of the operator to be inserted and moved therein with greater freedom.v The inner ends of the guards are of such size as to cover the openings O, and their outer ends are provided with openings G, through which the hand of the operator can be easily inserted, their purpose being to prevent light from entering the cabinet through the openings O when it is in use.

Within the cabinet, and on either side of the openings O, are disposed two verticallyarranged runs or ways, g, a pulley, z', being journaled in the top of each of said runs. A carriage, H, consisting of ashelf, p, having a shelf, b, secured thereto by upright standards 4() at either corner, is so constructed and arranged as to slide vertically between the ways g, being suspended by ropes or cords Z, which pass over pulleys i and are secured to counterbalancing-weights r, disposed in wells or runs 44, behind said ways.

Vertical openings I5 are formed in the righthand edges of the shelves p b, (See Fig. 5,) of

such size as to permit the plates to be easily passed through them.

In the rear portion of the cabinet, and eonveniently near the top thereof, is secured a shelf, 45, hinged to the left side, t, and directly below said shelf there is also a stationary shelf, fu.

A horizontally-arranged shaft, Li, is journ alcd at one end in bearings 16, secured to the i-nner face of the side t, its other end protruding through the side of the body A, and being provided with an ordinary crank, J, as shown in Fig. 6.

Two tanks, 20 and 21 preferably composed of copper, and of such height that they will easily pass under the shaft l-l, are disposed on the bottom of the cabinet.

The plate-rack E (sce Figs. 9 and 10) consists of a bar, 25, on which are secured at right angles thereto two or more elliptic arms, 26, the ends of said arms being bentto form hooks 27, which are adapted to receive and hold the plate Q, the bar 25 being provided with th umbscrews 4:7, by which it is attached to the crankshaft 14, the screws entering holes in said shaft. (Not shown.) The arms 26 are elastic, being preferably composed o1' sheet metal, and yield to receive the plate.

Each of the guards B is provided near i s outer end with an elastic band, 75, which contracts around the Wrist of the operator as the hand is inserted in the guard, thereby preventing tlie light from passing into the guards when in use.

In the use of my improvement, the dryplate to be developed is carried from the camera to the cabinet in the ordinary holder (not shown) and passed through the opening in the top of the cabinet inte the body of the saine and deposited on the top shelf of the carriage, after which the cover is closed. The hands of the operator are then inserted in the guards, and the plate taken from the holder and deposited in a tray (not shown) on the shelf p, containing the developing-liquid, the holder and its cover being then placed on a hanging shelf, a, which is suspended beneath the shelf p for that purpose. After the plate has remained in the developing-liquid a sufficient time, it is passed down through the opening 15 and secured in the plate-rack E, where it is revolved by means of the crank J in a liquid contained in the tank 20, to remove the surplus developing material.

If the plate is not thereby sufficiently cleaned it may be again immersed in Water contained in the tank 2l until all surplus chemicals are removed. After the bath in the tank 20 the plate is passed up through the opening 15 and deposited in atray (not shown) on shelf b, which contains the fixing liquid, and is then removed from the cabinet, and all after operations of finishing performed outside the cabinet in the ordinary manner.

rlhe shelves 45 and o are designed to Vhohl the brushes and bottles containing the chemicals of which the developing baths are composed.

rIlie object of the orange and. ruby colored glasses 7i' D LN is to color or regulate the light. in the interior of the cabinet, so as to obtain the best color for properly developing the plates, the glass talso permitting the operator to see into the cabinet while handling the plates during the process.

A curtain (not shown) may be suspended over the door BI and rear of the body A, to prevent the light from passing through the glasses D N, if desired.

The object of the carriage or elevator II to enable the operator to readily move the plates into different positions, and thereby submit them to different degrees of light during the process of developing, and also to move them conveniently near the tanks 20 and 2l. before taking them from the developing and fixing trays on the shelves p I.

I do not confine myself to thenumber of shelves shown in the drawings, as more or less may be used, or to the number of tanks shown, as one may be sufficient, or to the method described for securing the plate-holder to the crankshaft, as any suitable means may be employed for that purpose, or tothe use of the elasties 7 5, as they maybe dispensed with.

Having thus explained my invention, what I claim isl. The improved cabinet herein described, the same consisting of a body having openings in its sides for the hands of the operator, a cover, and a door in its front side, colored glass being setiii said cover and door and also in the rear and front of saidA body, funnelsliaped flexible guards secured to the body around said openings, a carriage or elevator provided with shelves and adapted to move vertically between runs or Ways in the inte` rior of said body, counterbalaneingwveights suspended from cords attached to said carriage and working on pulleys inthe tops of said runs, hinged and stationary shelves in the rear portion of said cabinet, a crank-shaft `journaled in the lower portion of the body, a plate-rack secured to said shaft, and tanks disposed in said body, substaiitially as described.
