The bracket or clamp 20 comprises a generally U-shaped body having the spaced legs 22 and 24, which are adapted to be fitted over the side wall lDa, of the tray Ill. The inner face of the leg 24 is preferably formed to abut a substantial area of the surface of the walls lOa, so that a tilting or rocking of the clamp is prevented, and the outer leg 22 is provided with a threaded opening 26, to receive a locking stud 28. The inner end of stud 28 bears against the outer face of the wall Illa, and may be turned between the locking and released position by a conventional knurled head 30. Preferably, the spacing between the legs 22 and 24 is great enough to accommodate the clamp to a pan or tray having a relatively large bead such as the bead lOb.
In order to accommodate the nozzle I8, the bracket 20 is provided adjacent its upper edge with a boss 32, which is bored to freely, slidably and rotatably receive the nozzle I8. A locking stud 34 is received within the threaded opening provided in the boss 32, and may be turned inwardly or outwardly by the knurled head 36 to either lock the nozzle la in a selected position of adjustment or to release the nozzle 18. In the locked position, it is noted that the inner end of the stud 32 bears directly against the side wall of the nozzle l8.
It will be appreciated that the complete device may be readily and economically manufactured. It will also be appreciated that it may be readily and quickly applied to and removed from trays or pans of widely varying constructions, and that, in the clamped position on a tray or pan, it is rigidly held against tilting or rocking. It will also be appreciated that the provision of the adjustment between the nozzle 18 and the bracket 20 permits the nozzle [8 to be adjusted both vertically, to accommodate it to pans or trays of differing depth, and also permits it to be rotative- 1y adjusted to selectively control the direction of flow of the sprays or streams of water from the several rows of orifices.
Although a specific embodiment of the invention has been described, as well as a specific application or use therefor, it will be appreciated that the invention may be applied to uses other than those specified, and may be embodied in forms differing widely from the illustrated form.
What I claim is:
1. In a device of the character described, for use with a tray or like container adapted to receive photographic specimens or the like, a combination of a tubular nozzle member adapted to be projected into said tray, said nozzle member having a first substantially vertical row of orifices through which liquid may be discharged to effect a circulation within the container, and having a second substantially vertical row of orifices through which liquid may be discharged in substantially horizontal streams to maintain said specimens in a separated condition, said rows being angularly displaced from each other.
2. In a device of the class described, the combination of a tubular nozzle adapted to project into a tray or like container and having one or more orifices in the side wall thereof through which liquid may be projected into said container, a bracket having a boss within which said tubular nozzle is rotatably and slidably received, said bracket having a U-shaped portion adapted to fit over the side of said container, and means for locking said bracket to said container and for locking said nozzle within said bracket.
3. A device for use in the washing of photographic prints comprising, in combination, a bracket adapted to engage over the side of a container, means for releasably and rigidly securing said bracket to the side of said container, a nozzle member provided with a plurality of orifices therein adapted to eject streams of liquid therefrom in the same general plane, said nozzle member being axially adjustable relative to said bracket whereby to permit its vertical relation with respect to the bottom of said container to be varied, and means for releasably and rigidly securing said nozzle member in axially adjusted relation with respect to said bracket.
4. A device for use in the washing of photographic prints comprising, in combination, a bracket adapted to engage over the side of a container, means for releasably and rigidly securing said bracket to the side of said container, a nozzle member provided with a plurality of orifices therein adapted to eject streams of liquid therefrom in the same general plane, said nozzle member being rotatably adjustable relative to said bracket whereby to permit the angular relation of said streams with respect to said container to be varied, and means for releasably and rigidly securing said nozzle member in rotatably adjusted relation with respect to said bracket.
