Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
63 words
The combination recited in claim 1 wherein said means comprises baffle means located intermediate said one side of said carpet and said first plenum chamber for selectively extending said plenum chamber into substantially air tight communication with said one side of said carpet or for providing an air passage to said housing in communication with said chamber and said side of said carpet.
Claim 2
Dependent Claim
79 words
The combination recited in claim 2 wherein said transport means includes at least one pair of tracks for tenter chains running lengthwise of the housing, adjusting means for moving said tracks widthwise of the housing relative to each other, and wherein said baffle means includes a first wall movable with said widthwise movement of said tracks and a second stationary wall mounted immediately adjacent said first wall for maintaining a substantially airtight seal therewith during movement of said tracks.
Claim 3
Dependent Claim
67 words
The combination recited in claim 3 wherein said adjusting means includes a plurality of pairs of carriages in said housing, each pair mounted on a common trackway, and a shaft having oppositely threaded terminal portions engaging in the carriages whereby rotation of said shaft in opposite Directions results in the movement of the carriages in said pairs widthwise of the housing toward and away from each other.
Claim 4
Dependent Claim
61 words
The combination recited in claim 1 further including a second plenum chamber disposed on the other side of said carpet, second air guiding means for directing air from said second chamber into contact with said other side of said carpet, and regulating means for selectively cutting off the flow of air from said pressure generating means to said second plenum chamber.
Claim 5
Dependent Claim
53 words
The combination recited in claim 5 wherein said pressure generating means comprises a plurality of enclosures mounted lengthwise of the housing in air communication with said housing and said first and second plenum chambers, each of said enclosures having an air circulating means mounted therein for collectively maintaining air pressure in said chambers.
Claim 6
Dependent Claim
59 words
The combination recited in claim 3 wherein said baffle means further includes a third wall extending from said second wall, said third wall including a plurality of portions running lengthwise of the housing and movable into and out of engagement with said chamber to complete a substantially airtight seal between one side of said carpet and said first chamber.
Claim 7
Dependent Claim
129 words
Apparatus for treating material such as carpeting comprising, an elongated generally enclosed housing, transport means for supporting and moving said carpet through said housing, first and second plenum chambers extending substantially the length of the housing, spaced therefrom and located on opposed sides of said carpet, a plurality of air-conditioning and circulating means for moving air under pressure into said chambers, movable air-directing means for channelling air along a first length of said housing into both of said plenum chambers for impingement against opposed sides of said carpeting and for recirculation of said housing without passing through said carpeting, and for channelling air along a second length of said housing from said first plenum chamber through said carpeting while preventing the flow of air from said second plenum chamber.
Claim 8
Dependent Claim
99 words
The combination recited in claim 7 further including a plurality of feed ducts along the length of the housing for channelling air from each of said plurality of air-conditioning means to a portion of said second chamber, and wherein said movable air-directing means includes rotatable cutoff walls located in each of said feed ducts for selectively preventing air along a length of said housing from travelling from said air conditioning means into said second chamber, and baffle means for extending portions of said first plenum chamber along a length of said housing into substantially airtight communication with said carpet.
Claim 9
Dependent Claim
80 words
The combination recited in claim 9 wherein said transport means includes at least one pair of tracks for tenter chains running lengthwise of the housing relative to each other, and wherein said baffle means includes first wall means running substantially the length of said first plenum chamber and movable with said widthwise movement of said tracks and second stationary wall means mounted immediately adjacent said first wall means for maintaining a substantially airtight seal therewith during movement of said tracks.
