Abstract
Abstract An evaporator core assembly for automotive air-conditioning service is disclosed in which attaching tubes, comprising the inlet, outlet and to some cases, an oil return tube, are removably secured to the core assembly in such a manner that the tubes may be adjusted to any desired angle in relation to the core assembly thereby reducing the service parts storage volume, required for making evaporator core assemblies of different or unique designs, as well as enabling the core assemblies to be made of different stack heights or dimensions. The removability is accomplished through the use of fittings of unique design, and nuts which are used in combination with these fittings.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
92 words
An evaporator core assembly comprising at least four dished, marginally joined sheets, said sheets each having adjacent a margin thereof means defining a passageway transversely of said core assembly and comprising an apertured dished portion, the dished portion of one endmost dished sheet of said evaporator core assembly being an apertured recessed dished portion, a female joint part of a separable joint having an axially extending portion positioned to extend into said recessed apertured dished portion of said dished endmost sheet, and means for securing said female joint part in said position.
Claim 2
Dependent Claim
92 words
An evaporator core assembly comprising at least four dished, marginally joined sheets, said sheets each having adjacent a margin thereof means defining a passageway transversely of said core assembly and comprising an apertured dished portion, the dished portion of one endmost dished sheet of said evaporator core assembly being an apertured recessed dished portion, a female joint part of a separable joint having an axially extending portion positioned to extend into said recessed apertured dished portion of said dished endmost sheet, and means for securing said female joint part in said position.
Claim 3
Dependent Claim
40 words
The evaporator core assembly of claim 1 and further comprising a cooperating sheet having an apertured flat portion overlying said apertured recessed portion of said endmost dished sheet, and means for joining said cooperating sheet to said endmost dished sheet.
Claim 4
Dependent Claim
54 words
The evaporator core assembly of claim 2, wherein at least some of said dished sheets adjacent to each other are spaced apart interiorly of the margins thereof to provide a passage communicating with said passageway, and wherein said cooperating sheet and said endmost dished sheet have a passage between them communicating with said passageway.
Claim 5
Dependent Claim
15 words
The evaporator core assembly of claim 1, and fins extending between some of said sheets.
Claim 6
Dependent Claim
16 words
The evaporator core assembly of claim 1, said female joint part comprising an internally threaded fitting.
Claim 7
Dependent Claim
35 words
The evaporator core assembly of claim 5, and in combination therewith a male threaded fitting threadedly engaging said female threaded fitting, and a tube extending through said fittings and in fluid communication with said passageway.
Claim 8
Dependent Claim
42 words
A evaporator core assembly of claim 1, and in combination therewith a male joint part of a separable joint in mating relation with said female joint part, and a tube extending through said joint parts and in fluid communication with said passageway.
Claim 9
Dependent Claim
58 words
The evaporator core assembly of claim 1, and further comprising a terminal sheet, an aperture in said terminal sheet, means securing said terminal sheet to a sheet of the core assembly with the aperture thereof in alignment with said dished portion of said dished endmost sheet, said securing means securing said female joint part to said terminal sheet.
Claim 10
Dependent Claim
34 words
The evaporator core assembly of claim 1, said female joint part extending oppositely to the endmost dished sheet and only approximately as far as the extent of any other part of said core assembly.
Claim 11
Dependent Claim
35 words
The evaporator core assembly of claim 1, wherein at least some of said dished sheets adjacent to each other are spaced apart interiorly of the margins thereof to provide a passage communicating with said passageway.
Claim 12
Dependent Claim
171 words
An evaporator core assembly comprising: a plurality of stacked cores, each said core comprising a pair of dished, marginally joined sheets, said sheets having complimentary dished portions adjacent a margin thereof, said dished portions being apertured, said cores assembled to provide through said apertures of said dished portions a passageway in said core assembly transversely of said sheets of said cores, an endmost dished sheet of said evaporator core assembly having the dished portion thereof recessed, a terminal sheet over a substantial portion of the said endmost sheet and having a portion thereof spaced from and generally parallel to the said endmost sheet, said portion of said terminal sheet being in laterally spaced relationship to said dished portion of said endmost dished sheet, an internally threaded tube joint fitting having a portion extending into said recessed dished portion of said endmost dished sheet, brazing means securing said fitting to said terminal sheet, said fitting extending outwardly of said seat to an extent not beyond the said portion of said terminal sheet.
Claim 13
Dependent Claim
171 words
An evaporator core assembly comprising: a plurality of stacked cores, each said core comprising a pair of dished, marginally joined sheets, said sheets having complimentary dished portions adjacent a margin thereof, said dished portions being apertured, said cores assembled to provide through said apertures of said dished portions a passageway in said core assembly transversely of said sheets of said cores, an endmost dished sheet of said evaporator core assembly having the dished portion thereof recessed, a terminal sheet over a substantial portion of the said endmost sheet and having a portion thereof spaced from and generally parallel to the said endmost sheet, said portion of said terminal sheet being in laterally spaced relationship to said dished portion of said endmost dished sheet, an internally threaded tube joint fitting having a portion extending into said recessed dished portion of said endmost dished sheet, brazing means securing said fitting to said terminal sheet, said fitting extending outwardly of said seat to an extent not beyond the said portion of said terminal sheet.
