Abstract

Abstract A developing and washing tray assembly comprising a receptacle having a peripheral wall and an intermediate partition wall defining below the peripheral wall adjacent compartments, one containing a fixing or developing solution, and the other compartment continuously draining or holding a top tray element in a position of non-use. The top tray being three-sided and normally supported in an overlying position to the compartment containing the solution when in use with the open side of the top tray draining into the drainage compartment and being inclined to continuously drain therein. The top tray including a handle to facilitate lifting, and a clamp to secure a sheet element being rinsed. The overlying top tray substantially preventing dilution of the developing or fixing solution as the treated sheet element is being rinsed.

Claims Analysis

Total Claims: 14
Claim 1
Independent Claim 190 words
A tray assembly for treating exposed photographic sheets or the like comprising, in combination: a receptacle having a partition therein with an upper support edge dividing said receptacle into a liquid treatment compartment and an adjacent liquid drainage compartment; a rinse tray having a bottom wall, a peripheral side wall surrounding said bottom wall along all but one side thereof, and a free edge portion along said one side of said bottom wall, said rinse tray being removably received within said receptacle in overlying relation to said liquid treatment compartment for preventing dilution of liquid in said compartment; support means on the bottom wall of said rinse-tray cooperating with said partition, and additional support means on said receptacle adjacent said liquid treatment compartment cooperating with said support means on said rinse tray for positioning said tray in overlying relation to the liquid treatment compartment and into angular draining relation towards said drainage compartment with the free edge portion of said bottom wall overlying said drainage compartment so that rinse liquid deposited on said tray will automatically drain past said free edge portion of said bottom wall into said drainage compartment.
Claim 2
Dependent Claim 190 words
A tray assembly for treating exposed photographic sheets or the like comprising, in combination: a receptacle having a partition therein with an upper support edge dividing said receptacle into a liquid treatment compartment and an adjacent liquid drainage compartment; a rinse tray having a bottom wall, a peripheral side wall surrounding said bottom wall along all but one side thereof, and a free edge portion along said one side of said bottom wall, said rinse tray being removably received within said receptacle in overlying relation to said liquid treatment compartment for preventing dilution of liquid in said compartment; support means on the bottom wall of said rinse-tray cooperating with said partition, and additional support means on said receptacle adjacent said liquid treatment compartment cooperating with said support means on said rinse tray for positioning said tray in overlying relation to the liquid treatment compartment and into angular draining relation towards said drainage compartment with the free edge portion of said bottom wall overlying said drainage compartment so that rinse liquid deposited on said tray will automatically drain past said free edge portion of said bottom wall into said drainage compartment.
Claim 3
Dependent Claim 45 words
The structure as claimed in claim 1 in which said receptacle has a peripheral side wall bordering the compartments, said partition upper support edge being disposed below the upper edge of the peripheral side wall and engaging said rinse-tray inwardly of said free edge portion.
Claim 4
Dependent Claim 21 words
The structure as in claim 1 in which said additional support means abutment comprises abutment means projecting inwardly from said receptacle.
Claim 5
Dependent Claim 44 words
The structure as claimed in claim 3 in which said receptacle has a peripheral side wall bordering the compartments, said partition upper support edge being disposed below the upper edge of said peripheral side wall and engaging said tray inwardly of said free edge.
Claim 6
Dependent Claim 37 words
The structure as claimed in claim 3 in which said abutment means and said partition upper support edge are disposed in vertically spaced relation and orient said tray into said angular draining relation toward said drainage compartment.
Claim 7
Dependent Claim 28 words
The structure as claimed in claim 1 in which said drainage compartment includes at least one drainage element adjacent the lower surface thereof for freely draining liquid therefrom.
Claim 8
Dependent Claim 23 words
The structure as claimed in claim 1 in which said tray includes handle mans for facilitating lifting of said tray off said receptacle.
Claim 9
Dependent Claim 27 words
The structure as claimed in claim 1 in which said drainage compartment removably receives and supports said tray on an edge thereof in a non-use stored position.
Claim 10
Dependent Claim 28 words
The structure as claimed in claim 1 in which said tray includes manually releasable clamp means for restraining a sheet on said tray as it is being rinsed.
Claim 11
Dependent Claim 38 words
The structure as claimed in claim 1 in which said support means on the bottom wall of said tray is a depending abutment inwardly of said free edge portion for orienting the tray with reSpect to said compartments.
Claim 12
Dependent Claim 236 words
A tray assembly for treating an exposed sheet or the like comprising: a lower tray having a bottom wall surrounded by a peripheral wall, a partition extending transversely of said peripheral wall and defining adjacent separate compartments, said partition having an upper support edge disposed in a plane below the upper edge of said peripheral wall, one of said compartments including a drainage portion for draining rinse liquid therefrom; and a rinse tray substantially corresponding in area to the other compartment for overlying the said other compartment, said rinse tray having a bottom wall, a peripheral side wall surrounding said bottom wall along all but one side thereof, and a free edge portion along said one side of said bottom wall projecting beyond the upper support edge of said partition and overlying said one compartment when said rinse tray overlies said other compartment, support means on the bottom wall of said rinse tray cooperating with said partition and additional support means on said lower tray adjacent said other compartment cooperating with said support means on said rinse tray for supporting said rinse tray in overlying relation to said other compartment and into angular draining relation towards said one compartment with the free edge portion of said bottom wall overlying said one compartment so that rinse liquid deposited on said tray will automatically drain past said free edge portion of said bottom wall into said one compartment.
Claim 13
Dependent Claim 236 words
A tray assembly for treating an exposed sheet or the like comprising: a lower tray having a bottom wall surrounded by a peripheral wall, a partition extending transversely of said peripheral wall and defining adjacent separate compartments, said partition having an upper support edge disposed in a plane below the upper edge of said peripheral wall, one of said compartments including a drainage portion for draining rinse liquid therefrom; and a rinse tray substantially corresponding in area to the other compartment for overlying the said other compartment, said rinse tray having a bottom wall, a peripheral side wall surrounding said bottom wall along all but one side thereof, and a free edge portion along said one side of said bottom wall projecting beyond the upper support edge of said partition and overlying said one compartment when said rinse tray overlies said other compartment, support means on the bottom wall of said rinse tray cooperating with said partition and additional support means on said lower tray adjacent said other compartment cooperating with said support means on said rinse tray for supporting said rinse tray in overlying relation to said other compartment and into angular draining relation towards said one compartment with the free edge portion of said bottom wall overlying said one compartment so that rinse liquid deposited on said tray will automatically drain past said free edge portion of said bottom wall into said one compartment.
Claim 14
Dependent Claim 30 words
The structure as claimed in claim 11 in which said upper and lower trays are rectangular, said drainage portion of said one compartment bordering one side of said other compartment.
