Abstract
Abstract An apparatus is disclosed for washing, etching or otherwise spray processing various substrates or photographic plates, and for spin drying the objects at the termination of the processing. The objects to be cleaned or otherwise processed are carried by a rotatable platform mounted above an elevated bottom portion of a treatment chamber. Nozzles for directing various liquids onto the articles are mounted on conduits for movement from a position proximate the chamber walls to a position extending inwardly over the rotatable platform. The lengths of the conduits carrying the nozzles are alternately varied in order to facilitate storage of the nozzles most proximate the cylinder wall. When the nozzles are retracted against the cylindrical wall they are located over a ledge provided in the walls.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
156 words
Apparatus for wetting and spin drying various articles, comprising: a. a housing defining a chamber, said chamber having a substantially closed lower end, side walls, and an upper end defining an opening therein; b. a rotatable platform mounted within said chamber above said lower end for carrying articles inserted into said chamber through said opening in said upper end; c. nozzle means attachable to a remotely positioned liquid source for spraying the articles carried by said rotatable platform; d. means mounting said nozzle means within said chamber for movement to a first position extending inwardly over said rotatable platform for the spraying of said articles and for movement to a second position proximate one of said chamber walls; e. drain means in liquid communication with said chamber adjacent said lower end thereof for exhausting the liquid introduced into said chamber; and f. cover means for substantially closing said opening in said upper end of said chamber.
Claim 2
Dependent Claim
156 words
Apparatus for wetting and spin drying various articles, comprising: a. a housing defining a chamber, said chamber having a substantially closed lower end, side walls, and an upper end defining an opening therein; b. a rotatable platform mounted within said chamber above said lower end for carrying articles inserted into said chamber through said opening in said upper end; c. nozzle means attachable to a remotely positioned liquid source for spraying the articles carried by said rotatable platform; d. means mounting said nozzle means within said chamber for movement to a first position extending inwardly over said rotatable platform for the spraying of said articles and for movement to a second position proximate one of said chamber walls; e. drain means in liquid communication with said chamber adjacent said lower end thereof for exhausting the liquid introduced into said chamber; and f. cover means for substantially closing said opening in said upper end of said chamber.
Claim 3
Dependent Claim
49 words
The apparatus of claim 1 wherein said means mounting said nozzle means includes a liquid carrying conduit having a first portion extending vertically upward into said chamber and a second portion extending perpendicularly to said first portion and mounting said nozzle in a downward direction at an end thereof.
Claim 4
Dependent Claim
34 words
The apparatus of claim 2 including means for rotating said first portion of said conduit about a longitudinal axis thereof, thus effecting the movement of said nozzle means to said first and second positions.
Claim 5
Dependent Claim
59 words
The apparatus of claim 3 wherein: a. said apparatus includes a double-action air cylinder attachable to said housing and containing a piston having attached thereto a rod; and b. means attaching said rod to said first portion of said conduit for rotation of said first portion of said conduit when said piston is moved by air within said cylinder.
Claim 6
Dependent Claim
42 words
The apparatus of claim 3 wherein: a. said substantially closed lower end of said chamber includes an elevated portion extending vertically upwardly from generally the central part of said lower end; and b. said rotatable platform is mounted above said elevated portion.
Claim 7
Dependent Claim
79 words
The apparatus of claim 3 wherein: a. said chamber walls generally define a cylindrical lower portion having a first diameter and a cylindrical upper portion having a second diameter greater than said first diameter, said cylinder portions defining a horizontally extending ledge therebetween; b. said first portion of said conduIt extends vertically through said ledge; and c. said nozzle is located proximate said cylindrical upper portion wall and over said ledge, when said nozzle is in said second position.
Claim 8
Dependent Claim
58 words
The apparatus of claim 6 including a plurality of nozzle means each attached to a conduit wherein, for alternate conduits, the part of said vertically extending portion of said conduit which extends above said ledge is of a sufficient length, facilitating movement of said nozzles proximate said cylinder upper portion when said nozzle is in said second position.
