Abstract
Abstract A furnace register humidifier having a rectilinear body formed by a pair of opposed side walls and a pair of end walls. A peripheral lip extends around an open end of the body for supporting the latter from perimeter edges of a floor furnace duct opening. A water trough is formed in an interior of the body extending along a length thereof such that an air flow channel is formed between the trough and a first one of the pair of side walls. The trough is adapted to receive a portion of a water wick extending across the air flow channel. A support is provided for the extended portion of the wick.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
136 words
A forced air furnace register humidifier, comprising: (a) a substantially rectilinear body adapted for placement in a furnace duct outlet, having a pair of opposed side walls, a pair of end walls and a generally open top; (b) means for supporting said body from a perimeter of a floor furnace duct outlet; (c) two parallel troughs for holding water formed in the interior of said body and having bottom and side walls; (d) an air flow channel formed centrally in said rectilinear body between said parallel troughs to allow passage of the air forced from said furnace; and (e) an air-permeable, porous, water-absorbent web, a raised central portion of said web extending across said air flow channel in the path of said forced air, and side portions of said web extending downwardly into said water-containing troughs.
Claim 2
Dependent Claim
136 words
A forced air furnace register humidifier, comprising: (a) a substantially rectilinear body adapted for placement in a furnace duct outlet, having a pair of opposed side walls, a pair of end walls and a generally open top; (b) means for supporting said body from a perimeter of a floor furnace duct outlet; (c) two parallel troughs for holding water formed in the interior of said body and having bottom and side walls; (d) an air flow channel formed centrally in said rectilinear body between said parallel troughs to allow passage of the air forced from said furnace; and (e) an air-permeable, porous, water-absorbent web, a raised central portion of said web extending across said air flow channel in the path of said forced air, and side portions of said web extending downwardly into said water-containing troughs.
Claim 3
Dependent Claim
27 words
A furnace register humidifier as defined in claim 1 wherein said means for supporting comprises a horizontal lip extending from the upper edge of said rectilinear body.
Claim 4
Dependent Claim
40 words
A furnace register humidifier as defined in claim 1 further comprising frame means for securing said downwardly-extending portions of said web in said water-containing troughs and for suspending said raised central portion of said web across said air flow channel.
Claim 5
Dependent Claim
236 words
A forced air furnace register humidifier comprising: (a) a substantially rectilinear body adapted for placement in a furnace duct outlet, having a pair of opposed side walls, a pair of end walls and a generally open top; (b) means for supporting said body from a perimeter of a floor furnace duct outlet; (c) a container for holding water having bottom and side walls formed in the interior of said body; (d) a pair of air flow channels formed in the interior of said body between said water container and respective ones of said side walls of said rectilinear body to allow passage of the air forced from said furnace; (e) an air-permeable, porous, water-absorbent web extending across said air flow channels in the path of said forced air, wherein a portion of said web is located in said water container; (f) means for holding a central portion of said wick proximate the bottom of said water container and means for affixing the ends of said web proximate said side walls wherein said ends of said web are attached proximate a bottom end of respective ones of said side walls; and (g) a pair of elastomeric fasteners wherein each of said web ends are folded around respective bottom portions of said side walls and are retained by respective ones of said elastomeric fasteners looped around respective bottom portions of said side walls over the associated web ends.
Claim 6
Dependent Claim
236 words
A forced air furnace register humidifier comprising: (a) a substantially rectilinear body adapted for placement in a furnace duct outlet, having a pair of opposed side walls, a pair of end walls and a generally open top; (b) means for supporting said body from a perimeter of a floor furnace duct outlet; (c) a container for holding water having bottom and side walls formed in the interior of said body; (d) a pair of air flow channels formed in the interior of said body between said water container and respective ones of said side walls of said rectilinear body to allow passage of the air forced from said furnace; (e) an air-permeable, porous, water-absorbent web extending across said air flow channels in the path of said forced air, wherein a portion of said web is located in said water container; (f) means for holding a central portion of said wick proximate the bottom of said water container and means for affixing the ends of said web proximate said side walls wherein said ends of said web are attached proximate a bottom end of respective ones of said side walls; and (g) a pair of elastomeric fasteners wherein each of said web ends are folded around respective bottom portions of said side walls and are retained by respective ones of said elastomeric fasteners looped around respective bottom portions of said side walls over the associated web ends.
