. ture during processing of film.
A further object of this invention is to provide a film-processing tank which is particularly adapted for the storage of the developing and fixing solutions when not being used in processing films, the storage being efiected in a manner which will effectively minimize oxidation of the solutions.
A'still further object of this invention is to provide a film-processing tank provided with temperature control means adapted to be connected to any convenient source of water under pressure.
A still further object of this invention is to provide a temperature control film-processing tank which is relatively simple in structure and cheap to manufacture.
The above and still further objects and advantages of the invention will become apparent upon consideration of the following detailed descriptionof the invention, when taken in conjunction with the accompanying drawings, wherein:
Figure l is a front elevational view, with parts brokenaway and in section, of the film-processing. tank of the present invention;
Figure 2 is a side elevational view, with parts broken away and in section, taken from the left of Figure l; and
Figure 3 is a top plan view of the filmmrocessing tank shown in Figure 1.
Referring now more particularly to the drawings, wherein lik reference numerals have been used throughout the several views to designate like parts, there is shown the film-processing tank of the present invention, generally designated by the numeral I; which includes a base II having two upstanding sockets i2, I3 disposed in side-by-side spaced relation with respect to each other and supported on the base.
Supported. in the upstanding socket I2 is a first vertically disposed receptacle I4 having a closed bottom and an open top. The receptacle I4 is fabricated of any suitable plastic or metallic, heat-conductive material, and is adapted to re- 2 Claims. (01. 95-96) ceive a developing solution. Disposed in side-bye side, spaced relation-with respect to the receptacle I4 is a second vertically disposed receptacle l5 which has an open top and a closed bottom,
the bottom being supported within the upstanding socket I3 oi. the base Il..
coefiicient of conductivity and is adapted to accommodatea fixing solution.
Each of the receptacles I4, I5 is provided with. a closure I6, I! for tightly sealing their respective open tops, andthereby provide a light-tight:- chamber for the reception therein of the film to; be processed. It is to be noted that only a rela-' tively small cross-sectional area of the contents."
of each of the receptacles l4, I5 will be exposed;
to the atmosphere during use, which effectivelyminimizes the oxidation of the developing and?- fixing solutions.
Disposed in abutting and confronting relationa ter jacket, designated by the referenc numeral! I8, the jacket being provided with an inlet I9; contiguous to and spaced from the closed upper: end, and an outlet 20 disposed in horizontali alignment with respect to the inlet I9. Disposed in abutting and confronting relation with respect; to the front face of the receptacle I5 and secured longitudinally thereof is a second water jacket 2! which is similarly provided with a horizontally aligned inlet 22 and outlet 23. spective inlets and'outlets of the water jackets I8, 2| are disposed at a level which is convenient for connection to a. sink, lavatory or any other suitable source of water under pressure. I
Disposed exteriorly of the water jacket I8 is an inlet conduit 24 which has one end extending through the inlet l9 and in communication with the interior of the jacket I8, and has its other end provided with a coupling 25 for'connection to a source of water under pressure. Ex-
. tending between the outlet 20 of the jacket I8 pipe. Disposed longitudinally within the" water 7 jacket I8 is a circulating pipe 28 which has one end supported in communication with the adja OFFICE The receptacle I5 is similarly fabricated of any suitable plastic or metallic material which has a relatively high.
The re-- ing pipe 28, the water jacket Hi, the connecting... pipe 26, the circulating pipe 29, the water jacket" 2|, and the outlet pipe 2'1 cooperate to forni a water-circulating system which is disposed in abutting and confronting relation with'respect to the respective receptacles to thereby. maintain the latter at any desired temperature.
Dependingly carried by. the cover l8 isafilm supporting clip 30, the cover I! being provided with'a similar 'clip, not shown Each of the cli'p's is adapted to engage-one end "of -a roll'- oi film to' be developed, the other endusually being weigh-ted for maintaining the-film in air unrolled" condition.-
Inac'tual use, the respective-receptaclesl4, 15 are supported within.theisockets lz, 13-, andithe coupling25 -is connected to-any' suitable source? "of water under :pressure. The cover l 6 is then removed and a developing solution: is" poured-into the-receptacle l4.- If desired, the voluinetric posed receptacle open at its top having its lower end portion supported in the other of said sockets for the reception of a fixing solution, a detachable closure closing the open top of each of said receptacles, clip means carried by each of said closures for dependingly supporting film to be treated, a water jacket arranged exteriorly of each of said receptacles and secured thereto, the jacket of each receptacle extending from a point adjacent to and .below its closure and-terminatingafta point adjacent to. and above'its supporting socket, a connecting conduit having one end :in-communication with one of said jackets and .having theother end in communication with the other orsaid'iackets, an inlet conduit having one .end inicommunication with said one of said jackets. and having the other end adapted to be connected'to a-source' oif water under pressure, and
