JOHN J. KELLY, OF NEW YORK, N. '55., AND JOSEPH F. TREERIDELL, 0F JERSEY CITY, NEW JERSEY.
To all whom it may concern:
Be it known that we, JOHN J. KELLY and JosnrrrF. TREERDELL, both citizens of the United States, and residents of New York city, in the county of New York and State of New York, and Jersey City, county of Hudson, New Jersey, respectively, have invented certain novel and useful Improvements in Photographic Apparatus, of which the following is a specification.
Our invention relates to photographic apparatus and has particular application to a portable structure of the class described adapted especially for use in developing, fixing and Washing plates and loading cameras.
In the present instance we have particularly in view as an object the provision of a simple, convenient portable structure capable of being dismantled and packed into a very small space, the frame or box of said structure when in its erected position being capable of containing all the essentials required in the operation of completely developing a plate, such as the developingtray, the wash-tank, the receptacle for the fixing bath and a drying-rack. We have also in contemplation providing means for introducing and circulating a body of water through the washtank so that a fresh supply of running fluid is at all times available in said tank for the purpose of thoroughly washing and cleaning the plates, thereby obviating the possibility of spotting, which is liable to occur when a large number of plates are washed in the ordinary manner.
With the above recited objects and others of a similar nature in view our invention consists in the construction, combination and arrangement of parts set forth in and falling within the scope of the appended claims.
WVhile we have herein shown and described by way of illustration one embodiment of our invention, it is of course to be understood that it is susceptible to modification and changes without exceeding the scope of the claims.
In the accompanying drawings like characters of reference indicate like parts in all the views.
Figure 1 is a perspective view of an assembled or erected structure embracing our invention; Fig. 2 is a central, vertical, longi- Specification of Letters Patent.

tudinal sectional view taken through the apparatus on the line 22 of F ig. 4; Fig. 3 is a detail view of the joint at the corner of the box or frame showing the manner of joining the edges; Fig. 1 is a top plan view of the device with the cover removed; Fig. 5 is a similar view with the cover applied, the hinged plates of the observation opening being thrown back; Fig. 6 is a vertical sectional view of the interior of the box taken on the line 66 of Fig. l, showing the manner of erecting therein the drying rack; Fig. 7 is a view taken on the line 77 of Fig. 6 showing the manner of retaining a plate within the rack.
Referring now to the accompanying drawings in detail, the letter A indicates the box or frame as an entirety such structure comprising the bottom portion 5, the longitudinal side members 6, the transverse end members 7 and the top 8, said top portion having erected thereon an observation shield indicated as a whole by 9, said shield comprising the hinged members l0, l0 and 11, 11 adapted to be folded down in the manner indicated in Fig. 5 to permit more light to enter through the observation opening 12. In case it is desired to shut off a portion of the light, the plates or covers are thrown up, as shown in Fig. 1, and the small curved shield 13 applied to the same in the manner shown, that is to say, the sides 11 are each formed with a small projection 13 with which the tongues l3 at the sides of the cap engage, said shield having an opening 1-l therein through which the process of development of the plates may be observed. The side and end members 6 and 7 are connected together by being joined in the manner indicated at 15 in Fig. 3, a lap joint being formed between the edges of the sides and ends so that the latter may be fitted one within the other. The top member 8 may be applied to the assembled sides and ends in the manner shown in Figs. 1 and 2, the edge portions 16 of the cover being flanged and adapted to fit over the top edges of the sides and ends. The boxlike member formed by the sides and end portions is also assembled upon the bottom 5 in the manner shown in Fig. 2, said bottom portion having a flange 18 extending around the same, within the lines of which flange the bottom portions of the sides and ends fit. The front of the box, which comprises one of the longitudinal sides 6, is cut away as at 19. Such cut-away portion is covered with a wall or facing of some flexible dark material, such as canvas or the like, as indicated at 20, such facing carrying flexible sleeves 21, 21, through which the hands of the operator may be in: troduced into the interior of the box to conduct the necessary work. Each of these sleeve members 21 is provided with an adjustable cuff 22 adapted to be snugly secured to the forearm or wrist of the operator in such a manner that the ingress of light to the box is prevented, the adjustment of the cuffs being for the purpose of accommodating the same to arms of different sizes. Each of the transverse ends 7 is provided with a window 23 preferably covered with ruby glass 2% to prevent white light entering and injuring the plates.
At the back of the box or casing or the longitudinal side opposite that containing the sleeves 21, we provide a relatively large window 26 covered with a suitable colored glass. Such side is also provided with two windows 23, 23 preferably covered with ruby glass to prevent white light entering and ruining the plates, and in order to adjust the amount of light permitted to pass through the windows each of the latter is preferably covered on the interior by a sliding shade or blind 25 which is under control of the operator. A sheet or piece of suitable translucent material 27 is placed over the observation opening 28 in the top 8 of the casing or box, said translucent sheet providing means through which the progress of the operation may be observed.
lVithin the assembled structure just described we place the appurtenances ordinarily used in the development of plates, films and the like, these comprising the developing-tray a, the fixing-bath receptacle Z), the wash-tank 0 and the drying rack (Z. The developing tray and fixing receptacle may be of any suitable nature as-may also be the wash-tank and the drying-rack. But, in thepresent instance, we have shown these two latter appurtenances of a particular construction designed especially for use in connection with this apparatus.
Referring first to the wash-tank 0, the latter preferably comprises a receptacle hav' ing vertically arranged strips 29, forming racks by which the plates are retained against displacement. If desired, the fixing-bath receptacle may be provided with such strips or similar racks for maintaining the plates out of contact with each other While immersed therein. As will be seen by reference to Figs. 2 and l, the wash-tank c is placed adj acent to one of the walls of the casing or boxing of the device and in order to have fresh water circulating at all times through the tank, we provide an inlet pipe 30 threaded onto thenipple 31, engaging with the small tubular part 31 communicating with the tank and extending therefrom through an opening in one of the sides of the boxing and having on the interior thereof a valve 32 through the medium of which the flow may be controlled by the operator, the outlet of the valve emptying directly into the tank at a point preferably near the upper edge thereof. The outlet for the water from the tank is in the nature of a small tube 33 communicating with the tank and extending therefrom through the wall of the box, and at the outside of the box this tube is designed to be connected with the nipple 33 which in turn is to be coupled with the tubing 3 1 leading to a point of discharge. By having inlet and outlet pipes arranged in the manner stated a continuous circulation of clean water is had through the tank and the rapid and ellicacious washing of the plates is accomplished.
The inlet pipe, it will of course be understood, is connected with any suitable source of supply, such pipe being preferably in the nature of a rubber tube or hose, while the outlet pipe also extends to a suitable point of discharge. To remove the wash tank from the box when it is desired to collapse the latter it is only necessary to disengage the pipes 30, 3% with their respective uipples 31, 33 from the small tubular parts 31, 33 and pull the tank away from the wall.
In Figs. 6 and 7 we have shown in detail our improved drying rack which may be installed at one end of the casing and is intended to receive a plurality of the plates so that the operation of developing, fixing and washing the plates may be uninterrupted and carried on with rapidity and convenience. This improved rack comprises one or more U-shmped'lnackets indicated at 35 in Figs. 6 and 7, said brackets being spaced apart to form a platform.
Suitably spaced apart, and secured to the wall of the boxing are the corrugated strips 36, 36, adapted to receive the vertical edge of he plate in the manner indicated in Fig. '7, the grooves or corrugations 37 in such strips receiving the edge of the plate and holding the same against movement. further secure the plate we provide a holder in the nature of a U-shaped bar or bail 38 pivoted at 39, so that such bar or bail may be swung upward over the top of the plates when not in use. After the plates have been assembled or arranged in the rack the bail may be swung downward in the manner in dicated in the drawings so as to secure the outer edges of such plates and preventing the latter tilting from the rack. A cover or shield, as at 10, is hinged at 41 to the side of the frame above the line of the upper edge of the plates, said cover having a deflecting flange 12 so that any moisture or water scattered during the operation of washing and In order to handling the plates will not splash upon and spot the plates, which latter will be protected by the cover. A small latch, as at 43, having a weighted end at is provided for holding the covering and the locking bail in an elevat'ed position when it is desired to have the rack open for the reception of the plates.
It will be noted that we have provided a construction of apparatus through means of which the operation of developing, washing and drying the plate may be accomplished and it will further be noted that our apparatus may be used for loading cameras in the daytime.
