Application January 7, 194.6, Serial No. 639,503

7 2 Claims. (01. 95-47) Our invention relates to a new and useful improvement in a photographic print washing receptacle in which the photographic prints may be deposited and whereby the prints after being deposited in the washer may be subjected to a cleansing bath while at the same time they are maintained in an agitated state.

Another object of the invention is the provision of a photographic print washing machine so arranged and constructed that the liquid contained within the washing pan is always being agitated and replenished and renewed.

Another object of the invention is the provision of a photographic print washer embodying a liquid container having an outlet delivery pipe connected therewith for continuously draining liquid therefrom and provided with an inlet pipe for continuously delivering liquid thereinto, the delivery of the liquid into the container being such that the liquid contained in the container is agitated at the bottom thereof and also at the top thereof thus preventing collection of sediment in, the pan and assuring an outflow of the sediment which is washed off of the prints.

Another object of the inventionis the provision of a photographic print washing machine which will be highly emcient in use, simple in construction, compact and light.

Another object of the invention is the provision of a photographic print washing device so arranged and constructed that sprays of Water may be delivered thereinto slightly below the water level so as to thoroughly agitate the prints which may be floating on the Water and prevent the same from becoming dry on their outer face.

Other objects will appear hereinafter.

It is recognized that various modifications and changes may be made in the detail of structure illustrated without departing from the invention in itself and it is intended that such variations and modifications shall be embraced within the claims which form a part hereof.

Forming a part of this specification are drawings in which,

Fig. 1 is a top plan view of the invention,

Fig. 2 is a view taken on line 2--2 of Fig. 1,

Fig. 3 is a sectional view taken on line 33 of Fig. 1, slightly reduced,

Fig. 4 is a fragmentary perspective view of one end of the invention,

Fig. 5 is a fragmentary view taken on line 55 of Fig. 3, slightly enlarged.

In the drawings we have shown the invention comprising a liquid container embodying the oppositely disposed side walls l0 and II and the 2 oppositely disposed end walls l2 and I3 and the bottom [4. An outlet drain pipe I5 is mounted on the wall 13 so as to communicate with the interior of the receptacle. It will be noted that the side walls II and ID are tapered in height being higher adjacent the end wall l3 than adjacent. the end wall [2. We have found that on a pan in which the distance between the end walls 12 and I3 is twenty-four inches a difference in the height of the side walls at their opposite ends would be approximately one-half inch. For instance, if the distance between the outside faces of the end walls l2 and I3 is twenty-four inches the height of the side walls l0 and II at the end wall l2 would be four inches and their height at end wall l 3 would be four and one-half inches, this variation in height being a gradual tapering. Consequently, this forms the pan or receptacle deeper at one end than it is at the other. However, when in use the upper edges of the side walls [0 and H would be extended parallel to a supporting surface such as a table on which the receptacle would be positioned. This is effected by mounting on the under face of the bottom I4 a supporting bar 34 which will elevate one end of the receptacle from the table or support on which it is positioned, and, in the size referred to, this elevation would be one-half inch. Thus the upper edges of the side walls would be parallel to the supporting table and yet the bottom of the container would be slanting toward the end l3.

Extended transversely of the receptacle or pan in spaced relation to the wall I3 is the partition l6 having at its lower edge spaced-apart notches or openings I1 formed therein, the lower edge thereof being angularly turned to provide the tongues l8 which are welded or otherwise suitably secured to the bottom l4. One end of the partition I6 is angularly turned as clearly shown in Fig. 1 so that it engages the corner 2| of the receptacle or pan. This angularly turned portion I9 has the angularly turned flange point 20 which engages the inner surface of the receptacle or pan at the corner and which is soldered, welded or otherwise suitably secured thereto. The opposite end of the partition I6 is provided with the angularly turned flange point 22 which engages against and is welded to the inner surface of the side wall l0. Thus there is provided within the container or pan, adjacent one end thereof, a chamber 23.

Mounted on the partition l6 aresupporting straps 24 in which is formed the slot 25 through which is projected the bolt 26 on which is threaded the wing nut 21. The lower end of the straps 24 are angularly turned to provide the cradle 24A in which rests the inlet delivery spray pipe 28 having an end thereof closed by the cap 29. This closed end is angularly turned to provide the substantially circular formation 30 in which are formed the spaced-apart openings 3!. These spaced-apart openings-3| are normally below the water level"33.. Formed in the main body of the pipe 28 are outlet openings 32 which are spacedapart and which are normally below or partially below the water line 33 so that water issuing out of the outlet openings 32 will issue as ,a spray which will serve to agitate the water adjacent its water line and keep the top of "the water which is contained within the pan ina state of agitation and movement sothat printsplaced in the water will be agitated and prevented from drying on their upper surfaces. 7

The pipe 28 is connected by the conduit 46 to a faucets which is connected to asuitablesouroe of water under pressure. .openedthe water will flow into the pipe .28 and outwardly through :the'openings 32 and 3!. -Com- -partment23 will of course fill with this water When the faucet is to the water level which may be maintained by adjusting the inlets to the outlets. When photographic printsare placed in the water in the receptacle or pan the-heavier solution washed .from the photographic prints will of course be precipitated. This heavier solution will not be permitted to accumulate on the bottom .14 of the pan because thesprays issuing from the outvlet openings 31 maintain this water in a constant state of agitation and prevents any sediment accumulating onthe bottom. This heaviermaterial will of course pass through the opening 1-,!

into the chamber 23 where it flows outwardly j surface and at its upper surface. .It is believed obvious that the pipe 28 may be adjusted upwardlyaand downwardly because of the presence of the slot in the supporting strips 24 thus accommodating the device to various containers or receptacles which may have different water levels without in any manner interfering with the normal operation and functionings of the sprays'of'water issuing from the outlet openings 32. :By this adjustment also the pipe 28 may be r 4 moved upwardly or downwardly water level depending upon the desires of the operator andthe effect which he desires'to produce.

What we claim as new is:

1. A print washer of the class described, comprising: a liquid receptacle embodying oppositely disposed side walls, oppositely disposed end walls and abottom; a transverselyxextended'partition .mountedin said container adjacent one of said end walls; a pair 'of hangers mounted on one face vof said partition; an inlet delivery pipe supported on said hangers and extending longitudinally of said partition; an angularly turned closed end on said'del-ivery pipe turned into substantially a acircular formation and projecting downwardly from said delivery pipe, said angularly turned end having outlet-openings formed therein and .said pipe having outlet openings formed therein;

the outlet openings in .said pipe being positioned above the outlet openingsin said angularly turned portion.

2. A print washer of the class described, comprising: a liquid-receptacle embodying oppositely disposed side wa'lls,.oppositely disposed end walls and .abottom; a transversely extended partition mounted in said container adjacent one ofsaid end walls; apair of hangers mounted on one face 7 of said partition; ,aninIe't delivery pipe supported on said hangersand extending longitudinally of said partition; an .angularly turned closed end on said delivery .pipe turned'into substantially a circular formation and projecting downwardly from said delivery pipe, said angularly turned .end having outlet openings formed therein and said pipe having outlet openings formed therein,

the outlet openings in saidtpipe beingpositioned above the outletopenings in said angularly turned portion; andmeans for adjusting said hangers vertically on said partition for. adjusting the position ofsaid inlet delivery pipe relatively .to the bottom of said container.
