Blickan, Inc., Weehawken, NJ., a corporation of New ork Filed May 21, 1962, Ser. No. 196,369 7 Claims. (Cl. 95--98) This invention relates to apparatus for use in the processing of color photographs and more particularly to such apparatus incorporating a modular arrangement whereby the apparatus readily is conditioned by the operator for use with any one of numerous processing procedures.

The development of color iilm and the making of color prints involve processes having numerous, distinct steps, the number and order of the steps depending upon the specic film or printing paper used and the desired photographic character of the finished product. The various chemical processing solutions are contained in individual stainless steel tanks, or vessels, and it generally is desirable to maintain the solutions at a relatively fixed temperature during the processing operation. The color negative, or exposed print, is immersed in the solutions in a prescribed order and in accordance with a predetermined timing sequence, with one or more washing steps interspersed through the particular processing procedure.

Color film is supplied in various standard sizes up to 8 X l0 inches, whereas color prints may run as large as 16 x 20 inches, Consequently, the processing apparatus includes a plurality of tanks of two sizes, one to accommodate the largest size film and the other to accommodate the largest size paper.

Inasmuch as different types of lms and printing papers require different specific processing sequences, it is desirable that the processing apparatus include a maximum flexibility with respect to the number and size of the tanks to be used and the positioning thereof relative to each other. The latter requirement is of importance as all, or at least a substantial portion, of the particular processing procedure must be carried out in a dark room.

Processing apparatus heretofore available has been designed primarily for use with a specific processing procedure, in which case the apparatus is limited for use with a specific grade, or type, of film or paper. Also, there has recently become available processing apparatus which includes provision for a limited degree of interchangeability of the solution-containing vessels, in which case the apparatus can be used with a few, but not all, of the available types of films and papers.

An object of this invention is the provision of apparatus for processing color photographs which apparatus includes convenient means whereby the operator can arrange the number, size and relative orientation of the solution-containing vessels thereby to adapt the apparatus for use in a processing sequence having the necessary number of steps.

An object of this invention is the provision of color photograph processing apparatus having adjustable means for removably supporting a plurality of solution-containing vessels in any one of numerous predetermined arrangements thereby to facilitate the particular processing procedure.

An object of this invention is the provision of color photograph processing apparatus comprising a tub for containing water, a plurality of vessels for containing the processing solutions, an adjustably-positionable arm for supporting the vessels in the water and cooperating means between the said arm and the tanks for retaining the tanks in predetermined, spaced, relation.

These and other objects and advantages will become apparent from the following description when taken with the accompanying drawings. It will be understood, however, that the drawings are for purposes of illustration and are not to be construed as defining the scope or limits of the invention, reference being had for the latter purpose to the claims appended hereto.

In the drawings wherein like reference characters denote like parts in the several views:

FIGURE 1 is an isometric View of apparatus made in accordance with this invention with the solution-containing vessels removed;

FIGURE 2 is a cross-sectional view taken along the line II-II of FIGURE 1 and drawn to an enlarged scale;

FIGURE 3 is a similar cross-sectional view taken along the line III-III of FIGURE 1;

FIGURE 4 is a plan view of the removable bracket arm;

FIGURE 5 is a side View thereof;

FIGURE 6 is an isometric view of a vessel adapted to contain a processing solution;

FIGURE 7 is a fragmentary plan View of the apparatus showing one arrangement of the larger-size solutioncontaining Vessels;

FIGURE 8 is a similar view showing an arrangement of the smaller size vessels; and

FIGURE 9 is an enlarged, fragmentary View, in cross section, showing an arrangement for adjusting the locating pin relative to the vessel flange, thereby to effect a leveling of the vessel when suspended within the tub.

Referring, now, to FIGURE l, the numeral 10 identifies a generally rectangular tank, preferably made of stainless steel and supported on suitable legs. Extending upwardly from the tank is a panel 12, which normally carries the necessary accessories such as thermometers, control devices and manually-operable valves for controlling the flow of water into the

separate tubs

13 and 14, which tubs are provided with overiiow outlets 15 and 16, respectively. In accordance with conventional practice, the tub 14 is used for the washing step in the processing procedure and a continuous circulation of water is maintained therethrough. The larger tub 13, into which the various solution-containing vessels are suspended, is filled with water to a desired level thereby to maintain the processing solutions at a uniform temperature.

The top of the tank lil is a mono-planar structure made up of the rear plates 17, 18, corresponding front plates 19, 2), a divider plate 21 and the

side plates

22, 23. These plates, made of strainless steel, are secured together to form a rigid structure which, in turn, is secured to the tub, thereby defining the openings for the

tubs

13 and 14. For purposes which will be described in detail hereinbelow, the plates are provided with spaced, aligned holes at the forward edges thereof. Further, the forward edge of each plate is reversely bent to form channels which are substantially co-extensive with the length of the plates.

FIGURE 2, which is an enlarged cross-sectional view taken along the line II-II of FIGURE 1, shows the side plate 23 having a downwardly-depending portion 24 disposed within a

clip

2,5 that is welded, or otherwise secured, to a side wall of the tub 10 and the reverse bend at the forward edge forming the channel 26. Similarly, FIGURE 3 shows the divider plate 21 supported by the tank partition wall 27 and having both edge portions reversely bent to form the

channels

28 and 29. It will now be apparent that the tank top is a unitary structure affixed to the tub to lie in a plane somewhat lower than the top of the tub walls.

In order to provide for a maximum degree of flexibility whereby the operator can position a required number of arras/ie n E solution-containing vessels in a preferred positional orientation within the tub I3, there is provided a removable bracket arm as shown in FIGURES 4 and 5. This bracket .arm 3Q, made of stainless steel, has notched corners to permit bending the side edges downwardly to form the side walls 31 (which provide structural rigidity) and the lips 32 adapted -to iit Within the channels formed in the top of the tank, such as the facing channels 26 and 2S shown in FIGURES 2 and 3. Attention also is directed to the two rows of spaced holes 33 and 34 formed in the bracket 30, the longitudinal spacing of the holes corresponding to that of the holes formed in plates I7, I9, 2l and 23, as shown in FIGURE l.

Referring back to FIGURE l, the opening in the tub I3 is square and the length of the bracket fail (FIGURE 4) is such that the bracket spans the tub opening, in either direction, when the lips of the bracket are positioned in the channels formed in opposite plates I7, I9, or 21, 23. Inasmuch as these channels extend substantially the full length of the plates, the bracket 3u is slidably positionable to divide the tub opening into two sections of desired proportions.

The various chemicals utilized in the processing operation are contained in individual stainless steel tanks or vessels With the exception of the bleaching solution which preferably is contained in a vessel made of brass to resist the corrosive action. These vessels are made in two standard sizes, one for tilm and one for printing paper. Appropriate baskets are provided for retaining a quantity of either iilms or papers in spaced-apart position within the appropriate vessel, and suitable light-tight covers are provided for each vessel. Such baskets and covers are standard equipment and form no part of the present invention.

FIGURE 6 shows one of the small vessels for containing a processing solution and which is adapted to accommodate a plurality of color films. A plurality of such vessels are provided each having a capacity of approximately one gallon. It will be noted that the vessel, identitied by the numeral 3S, comprises a rectangular body portion 35, having a tiat skirt, or flange 37, secured thereto at the open end and which carries four locating pins 38 and 3S having tapered ends. The spacing between the adjacent pins 3S is equal to that of the adjacent pins 38 and is a multiple of the spacing between adjacent holes in the plates forming the top cover of the tank 10 (see FIG- URE l) and the holes 33 and 3d formed in the bracket arm (see FIGURE 4). Specifically, in the actual apparatus, the spacing between adjacent holes 33, inthe bracket arm, is one inch, and the spacing between the locating pins 38 of the vessel is three inches. The length of the iiange 37, of the vessel 35, is somewhat less than the width of the small tub 14 (see FIGURE l) and somewhat less than one half that of the larger, square tub I3, for purposes which will become apparent as the description proceeds.

A set of larger vessels is also provided, these vessels having a capacity of approximately 31/2 gallons and designed to accommodate a plurality of prints having a maximum size of, say, 16 X 20 inches. Each of the larger vessels is provided with a tlangc and four locating pins such as the flange 37 and the

pins

38, 38 shown in FIG- URE v6. Further, the larger vessels are somewhat narrower than the smaller vessels and the length of the flange (on the larger vessels) is such that it will span the opening in the larger tub I3.

Reference now is made to FIGURE 7 which is a fragmentary plan view of the tank itl showing the plates 7-23 (which form the tank cover), each plate being provided with a row of uniformly-spaced holes (here identitied by the related reference numerals Ia-23a) and upturned free edges forming the channels (here identiied by the related numerals 17h-23h).

As stated hereinabove, the small tub 14 contains the circulating water for the Washing step of the processing procedure. In the case of prints, a number of said prints is carried by a suitable basket which is disposed within one of the larger vessels, such as the vessel ttl in FIGURE 7. The vessel is suspended on the opposed plates I8, Ztl with the locating pins 4I passing through the correspondingly-spaced holes of the series 18a and 26a. As is well known in this art, the vessel 4t) has perforations in the side walls affording the iiow of water through the vessel and into contact with the contained prints. The described arrangements provide a hrm support for the vessel while permitting easy removal and re-positioning thereof. Further, in the event two such wash vessels are required, they can be positioned in side-by-side relation.

A plurality of similar vessels can be suspended in the large tub I3 in a similar manner, with the vessels positioned in side-by-side relation and extending lengthwise or crosswise of the tub as shown, for example, by the dotted outline of the vessel identied by the numeral 42. In actual practice, the large tub I3 will accommodate seven of the larger size vessels, which, together with the wash vessel liti, provides a capacity suitable for the processing of colored prints in a seven-step procedure, exclusive of the washing steps.

To convert the apparatus for use in developing colored lms, the larger vessels are replaced by the smaller vessels which can be arranged quickly and easily by the operator in accordance with the specic processing method to be used with the particular ilm. One such arrangement is shown in FIGURE 8. Here the bracket arm 36B (see also FIGURE 5 is positioned to span the tub I3, with the lips 32 of the bracket arm resting in and slidable along the channels 2lb and 23h formed in the opposed plates 2l and 23, respectively. The individual vessels 35 are retained in the desired position by the associated locating pins passing through appropriate holes formed in the bracket arm 30 `and one or the other of the opposed plates I7 and I9. One or more wash vessels d3 similarly can be suspended in the tub 14, as shown. It will be apparent that the bracket arm 3@ can be positioned at a right angle to the position illustrated in FIGURE 8 whereby the vessels 35 are positioned by the locating pins passing through the aligned holes in the bracket arm and one or the other of the

opposed plates

21 and 23. It will further be apparent that the geometry of the described arrangement is such that a plurality of the small vessels can be suspended in, say, the rear portion of the tub I3 and a plurality of the larger vessels suspended in the front portion of the tub, all for the purpose of adapting the apparatus for use with a particular processingY procedure or procedures.

In certain steps of the processing procedure, it is advantageous to have the vessel suspended within the tank in a very nearly vertical plane irrespective of the level of the apparatus. Toward this end, some, or all, of the locating pins can be adjustably mounted on the associated vessel flange. One such arrangement is illustrated in FIGURE 9 which is an enlarged view, in cross section, showing a portion of the vessel ange 37. In this case, the locating pin has its tapered end 45 terminating in a circular shoulder i6 from which the threaded shank eX- tends through a threaded hole formed in the iiange. Firmly secured to the end of the shank is a. knurled, finger-operable knob 47. The maximum diameter of the pin end 45 is less than the diameter of the locating holes formed in the top surface of the tank. Consequently, when the vessel is suspended within the tank, it is supported by the circular shoulders of the locating pins. It will be apparent, then, that suitable rotation-o1c one or more of the vessel locating pins will effect a leveling of the vessel, as desired.

Although the vessels hereinabove described have rectangular bodies for containing the processing solution, it will be apparent the invention is not restricted to vessels of such specic form. Circular, or other body shapes, may be utilized, each such vessel having an outwardlyextending iiange which carries the locating pins for the purposes hereinabove set forth.
