Abstract
Abstract The device is characterized by a cabinet including a light-tight processing chamber having a floor, a pair of laterally spaced side walls of congruent triangular configurations, a bellows cover, and a pair of closure panels for closing an access opening provided between the side walls. A repositionable lamp house is attached to and directed downwardly through the cover, while a pair of opaque sleeves is extended through the closure panels for facilitating access to the processing chamber. A readily accessible paper safe and a receptacle for a roll processing tube are provided beneath the floor of the chamber.

Claim 1
Independent Claim
300 words
A color enlarging device for photographically fixing enlarged copies of color images comprising: A. a cabinet including a light-tight processing chamber defined by a floor, a pair of laterally spaced upright walls, each being of a right-triangular configuration and having an inclined top edge surface, and a front wall comprising a jamb of rectangular configuration circumscribing an access opening, a pair of closure panels for closing said access opening and a light baffle interposed between said pair of closure panels and said jamb including an endless groove and an endless rib adapted to seat in said groove, and a top closure for said processing chamber including a vertically extensible bellows attached to said walls; B. a pair of opaque sleeves mounted on said pair of closure panels and extended therethrough for facilitating access to said processing chamber; C. a roll processing tube adapted to be employed in processing exposed sensitized paper within said processing chamber; D. means defining a receptacle for said processing tube communicating with said processing chamber through an opening formed in the floor of said chamber; E. a paper safe communicating with said processing chamber through another opening formed in the floor of said chamber and a closure panel for closing the other opening; F. an easel for receiving and supporting a sheet of sensitized paper adapted to be seated in a light-tight closing relationship with the opening formed in the floor of said chamber; G. a lamp house connected to said bellows communicating with said processing chamber and having an optics system aligned with the easel for projecting a color image on a sheet of sensitized paper supported by the easel; and H. means including an inclined rail mounted on said cabinet supporting said lamp house for movement in a vertical plane above said processing chamber.

A color enlarging device for photographically fixing enlarged copies of color images comprising: A. a cabinet including a light-tight processing chamber defined by a floor, a pair of laterally spaced upright walls, each being of a right-triangular configuration and having an inclined top edge surface, and a front wall comprising a jamb of rectangular configuration circumscribing an access opening, a pair of closure panels for closing said access opening and a light baffle interposed between said pair of closure panels and said jamb including an endless groove and an endless rib adapted to seat in said groove, and a top closure for said processing chamber including a vertically extensible bellows attached to said walls; B. a pair of opaque sleeves mounted on said pair of closure panels and extended therethrough for facilitating access to said processing chamber; C. a roll processing tube adapted to be employed in processing exposed sensitized paper within said processing chamber; D. means defining a receptacle for said processing tube communicating with said processing chamber through an opening formed in the floor of said chamber; E. a paper safe communicating with said processing chamber through another opening formed in the floor of said chamber and a closure panel for closing the other opening; F. an easel for receiving and supporting a sheet of sensitized paper adapted to be seated in a light-tight closing relationship with the opening formed in the floor of said chamber; G. a lamp house connected to said bellows communicating with said processing chamber and having an optics system aligned with the easel for projecting a color image on a sheet of sensitized paper supported by the easel; and H. means including an inclined rail mounted on said cabinet supporting said lamp house for movement in a vertical plane above said processing chamber.
Claim 3
Dependent Claim
173 words
A color enlarging device for providing enlarged color images taken from negatives, slides and the like comprising: A. a cabinet having means defining therein an internal, light-tight chamber including a pair of upstanding side walls, each of said walls being of substantially right-triangular configuration including a substantially horizontally oriented bottom edge surface, a front edge surface normally related to the bottom edge surface, and a downwardly inclined top edge surface, a removable closure panel defining an access door for the processing chamber, and a tubular bellows attached to said pair of side walls defining an extensible cover for said processing chamber; B. an easel for receiving a sheet of sensitized paper disposed within said chamber; C. means for photographically exposing a sheet of sensitized paper received by said easel including a movable lamp housing externally related to the chamber and adapted to project a photographic image on said sheet; and D. means for facilitating digital manipulation of the sheet of sensitized paper within said chamber including a flexible sleeve mounted on said cabinet.
Claim 4
Dependent Claim
173 words
A color enlarging device for providing enlarged color images taken from negatives, slides and the like comprising: A. a cabinet having means defining therein an internal, light-tight chamber including a pair of upstanding side walls, each of said walls being of substantially right-triangular configuration including a substantially horizontally oriented bottom edge surface, a front edge surface normally related to the bottom edge surface, and a downwardly inclined top edge surface, a removable closure panel defining an access door for the processing chamber, and a tubular bellows attached to said pair of side walls defining an extensible cover for said processing chamber; B. an easel for receiving a sheet of sensitized paper disposed within said chamber; C. means for photographically exposing a sheet of sensitized paper received by said easel including a movable lamp housing externally related to the chamber and adapted to project a photographic image on said sheet; and D. means for facilitating digital manipulation of the sheet of sensitized paper within said chamber including a flexible sleeve mounted on said cabinet.
Claim 5
Dependent Claim

Claim 6
Dependent Claim
37 words
The device of claim 3 further comprising a receptacle for supporting said tube in an accessible relationship with the chamber and a safe for supporting a plurality of sheets of sensitized paper in communication with the chamber.
Claim 7
Dependent Claim
47 words
The device of claim 4 wherein said easel comprises a light-tight closure member for said receptacle and said safe includes a normally closed access opening for affording access from the exterior of said cabinet, and a normally closed access opening for affording access from said processing chamber.
Claim 8
Dependent Claim
18 words
The device of claim 2 wherein said closure panel comprises one of a pair of similar closure panels.
Claim 9
Dependent Claim

Claim 11
Dependent Claim
204 words
In a color enlarging device for providing enlarged color images taken from negatives, slides and the like, the combination comprising: A. a cabinet having defined therein a processing chamber normally maintained in a light-tight condition defined by means including a pair of upstanding side walls, each being characterized by a substantially horizontally oriented bottom edge surface, a front edge surface normally related to the bottom edge surface, and a downwardly inclined top edge surface, a removable closure panel defining an access door for the processing chamber, and a tubular bellows attached to said pair of side walls defining an extensible cover for said processing chamber; B. an easel disposed within said chamber adapted to receive a sheet of sensitized paper; C. means for photographically exposing a sheet of sensitized paper received by said easel including a movable lamp housing externally related to the chamber; D. a roll processing tube disposed within said chamber for receiving said sheet of sensitized paper while a light-tight condition for said chamber is maintained; and E. means including a flexible sleeve extended into the chamber for facilitating simultaneous digital manipulation of the sheet of sensitized paper and said roll processing tube while maintaining the chamber in a light-tight condition.
