UNITED STATES PATENT OEErcE.

vN. F. ENGLISH, OF IIARTIIAN'D, YFRIONT.

PHOTOG RAPHIC APPARATUS.

Specification forming part of Letters Patent No.

and I do hereby declare that the following' is.

a full,elear, and exactdescription ot' the same, reference being' had to the accompanying drawings, forming part ot this specification,

Figures l and 2 are vertical sections ot the apparatus, taken at right angles to each other, representing it in condition l'or transportation. Fig. 3 is a transverse vertical seetion ot' the apparatus in condition for use. Fig'. 4 is a front view, partly in sectiomrepresenting the apparatus in the same condition as Fig'. 2.

Similar letters of reference indicate corresponding parts in the several ligures.

This invention consists in a certain arrangement ot movable supplementarylids or liaps attached and fitted to the lid of a trunk or box, whereby the said trunk orbox may be converted expeditiously into a dark room of about double its size.

It also consists in a certain combination ot a vessel for containing` developing solution and a fountain or vessel for water, and a certain system of valves in. connection therewith, whereby the flowing ot' the said solution over the plate and of the water for washing,` oft the said solution are controlled by the hand ofthe operator outside of the dark room, and the said solution and water are caused to be delivered onto the picture from the saine tube or conductor, so that the water may wash away all trace of the solution from the said conductor after the developing of a picture, and so prevent the staining of the next picture.

To enable others to make and use my invention, I will proceed to describe its construction and operation.

A is the bottom, B B the ends, C the front, and C the back, of a box or trunk, of oblong' quadrangular lform, ot' wood or metal, all rigidly connected together.

D is the lid hinged to the back C', as shown at a, and made deep enough for the reception of the piece E, which is to forni the upper part 35,3055 dated )Iay 30. i962.

off the lront thereof, and the pieces (i G,which are to l'orm the upper parts ot' thesides thereot, the lid itsell when brought to an uprightposition forming' the back ot' the upper part ot' the chamber, as shown in Fig'. l. 'lhe top piece, E, is hinged at l), Figs. l and i), to the t'ront ot' the lid, and the end pieces, (l G, are hinged to the ends thereotat rf e, Figs. fand 2. The piece F is not attached to the lid, but when the box is packed t'or transporiation is placed within the lid inside ot'the pieces GG and E, as shown in Figs. l and 2, which are then vfolded into thelid. To extend the chamber in the condition lor use, (represented in Figs. and 4,) the lid is lirst raised to an u pright position. The end pieces, G (el, are then opened out at rig-ht angles to it and brought on the tops of the ends l B ot thebox, the top piece, E, is moved up toa horizontal posi tion and placed on ledges d fl, formed tor its reception on the pieces G (t, and the t'ront piece, F, being' provided with hinge-sockets e e, has the said sockets slipped onto pins attached to the t'ront ol' the box, and has its upper rabbcted edge placed under the top piece, E, and its ends placed iiigrooves d d in the end pieces, G G. The lid l) and the several pieces E F G G are then allseeured lirmlyin place by means ol hooks fj', attached to the top piece, E, said hooks catchingonto studs t/ g on the upper edges of the trout and end pieces. The box A 15 C C, ltermine, the lower part ot' the chamber, has arranged within it the box Il tor cinitaining the sensitizing-bath, the dripping-pan I, and the fixing-bath J, and in the remainder ol' the space within it the watenfonntain l, the jar Il, from which the developing solution is used, and such bottles and other articles as it may be desirable to place therein, maybe packed for transportation.

Near the lett-haml end ot the trout piece, F, there is an opening tor the admission ot the lett hand otf the operator to ei'tfect the neces sary manipulations, sueh ,peninglileing fitted with a cloth sleeve, (awilh an. elastic band to tit the wrist ot' the operator. Xear the lett hand end ot' the top piece F there isan openingl for the reception oli' the movable eye-piece M, through which the operator views the processes of sen sitizing and developing, such eyer piece being made large enough to admit both eyes, and formed to iit the face to exclude the light as much as possible. In one Of the end pieces there is an opening, h, which is glazed with colored glass or' covered with colored paper to admit only sufficient light to enable processes to be viewed.

The water-fountain K is made with a flan ge, i', at the top to rest on the top E of the chamber, and with a nozzle, j, near the bottom to enter a hole in the right-hand end piece, G, against which the back of the said fountain rests, as shown in Fig. l. At the inner end of this nozzle there is formed the seat for a valve, 7u, which is attached to a lever, Z, and closed by a spring, m, applied to the said lever. The fountain is secured against the end of the chamber by one of the hooks f catching a stud, i', on the top of the flange 1f. Between the eyepiece M and the right-hand end of the top piece'E Ithere is provided in the said top piece a hole for the reception of the jar L, which is provided with a 'flange to rest on the margin of the said hole. In the bottom of this vessel there is a valve, p, which is connected with a lever, q, at the top, and closed by a spring, 7', applied to the said lever, and from the seat of this valve there descends a nozzle, s.

N is a T-shaped shoe-piece fitted to the nozzleyl of the water-fountain and the nozzle s of the jar L in such manner as to connect both nozzles with one outlet, t, situated over the dripping-pan I, and that Water flowing to the said outlet from the fountain to wash the developing solution from apicture shall pass the nozzle s and wash outfrom the said shoe-piece the developing solution, which will have been left on the inner surface of the said shoe-piece, and which if allowed to remain would discolor the next picture. The apparatushaving been extended and arranged, as represented in Figs. 3 and 4 and above' described, the operator places himself in front of it and inserts his left hand through the sleeve G to handle the plates and places his eye to the eye-piece to observe its condition. The valve-levers q and Z are so situated as to be conveniently worked by the right hand to develop the pictures, the Valve p being first opened to allow the developing solution to run from the jar L over the picture, and the valve k being afterward opened to allow the water to run from the fountain K to wash the solution both from the picture and from the shoe-piece N.

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

l. The combination, with the box A B B C C and the lid D, of the end pieces, G G, top piece, E, and front piece, F, the whole applied and arranged substantially as herein specied.

2. Combining the water fountain or vessel K and the vessel L, from which the ,developing-fluid is used, by means of valves k p and a shoe-piece, N, or its equivalent, making one outlet for both vessels, substantially as and for the purpose herein specified.
