Claims Analysis
Total Claims: 17
Claim 1
Independent Claim
147 words
In a coating hood adapted to minimize fluid movement between an enclosed coating area and the environment surrounding same, said hood being provided with imperforate sidewalls, an imperforate top wall extending therebetween and opposite end sections including end walls having appropriate openings to accommodate the passage therethrough of articles to be coated and a central section defining a coating area, said hood further being movably positioned immediately above a conveyor for transporting articles thereto and therethrough and so positioned by lifting means located above and connected to the hood, said lifting means comprising a supporting frame member and a support means affixed to said hood such that vertical movement may be imparted thereto, said hood further including a plurality of fins positioned internally thereof and along the sidewalls of each section thereof, said fins extending inwardly from said sidewalls in a direction substantially transverse to such sidewalls.
Claim 2
Dependent Claim
147 words
In a coating hood adapted to minimize fluid movement between an enclosed coating area and the environment surrounding same, said hood being provided with imperforate sidewalls, an imperforate top wall extending therebetween and opposite end sections including end walls having appropriate openings to accommodate the passage therethrough of articles to be coated and a central section defining a coating area, said hood further being movably positioned immediately above a conveyor for transporting articles thereto and therethrough and so positioned by lifting means located above and connected to the hood, said lifting means comprising a supporting frame member and a support means affixed to said hood such that vertical movement may be imparted thereto, said hood further including a plurality of fins positioned internally thereof and along the sidewalls of each section thereof, said fins extending inwardly from said sidewalls in a direction substantially transverse to such sidewalls.
Claim 3
Dependent Claim
39 words
The improvement claimed in claim 1 in which said hood is provided with at least one side coating gun affixed to said hood, said side coating gun being adapted to deliver a coating material to the coating area therein.
Claim 4
Dependent Claim
64 words
The improvement claimed in claim 1 in which said hood is positioned immediately above a conveyor for transporting articles therethrough, said conveyor comprising a perforate belt member and a perforate channel member each communicating with a distributor means sealingly positioned below said conveyor, said distributor means being adapted to deliver a coating material upwardly through said conveyor to the coating area in said hood.
Claim 5
Dependent Claim
17 words
The improvement claimed in claim 1 wherein said fins are aligned in opposing pairs along opposite sidewalls.
Claim 6
Dependent Claim
60 words
The improvement claimed in claim 1 wherein said fins are each provided with a first and second side and an upper and lower side, said first side being adjacent and conforming to the sidewalls of said hood, said second sides each being shaped to conform to the shape of an article to pass through this hood and between opposing fins.
Claim 7
Dependent Claim
28 words
The improvement claimed in claim 1 wherein the fins are pivotally mounted within the hood to permit passage of a downed or misaligned article without raising the hood.
Claim 8
Dependent Claim
14 words
The improvement claimed in claim 1 wherein said fins are affixed to said sidewalls.
Claim 9
Dependent Claim
47 words
The improvement claimed in claim 7 where said conveyor comprises a perforate belt member and a perforate channel member each communicating with distributor means sealingly positioned therebelow, said distributor means being adapted to deliver coating material upwardly through said conveyor to the coating area in said hood.
Claim 10
Dependent Claim
75 words
The improvement claimed in claim 8 wherein detecting means are affixed to said hood in such a manner as to detect a downed or misaligned article before said article reaches said hood, said detecting means being adapted to trigger an activating mechanism on contacting a downed or misaligned article causing activation of said lifting means thereby lifting said hood and said detecting means upwardly above the path of travel of a downed or misaligned article.
Claim 11
Dependent Claim
30 words
The improvement claimed in claim 9 in which at least one side coating gun is affixed to said hood and adapted to deliver coating material to the coating area therein.
Claim 12
Dependent Claim
77 words
The improvement claimed in claim 7 in which a detecting means is affixed to said hood in such manner as to detect a downed or misaligned article before said article reaches said hood, said detecting means being adapted to trigger an activating mechanism on contacting a downed or misaligned article causing activation of said lifting means thereby lifting said hood and said detecting means upwardly out of the path of travel of said downed or misaligned artIcle.
Claim 13
Dependent Claim
30 words
The improvement claimed in claim 11 in which at least one side coating gun is affixed to said hood and adapted to deliver coating material to the coating area therein.
Claim 14
Dependent Claim
126 words
A vertically movable hood positioned over a conveyor for transporting articles therethrough, said hood being connected to lifting means comprising a supporting frame member located at least partially above said hood, a support member affixed to said hood and to a portion and said frame member above said hood and adapted to impart vertical movement to said hood, and detecting means affixed to said hood in such manner as to sense a downed or misaligned article before said article reaches said hood, said detecting means being adapted to trigger an activating mechanism on contacting a downed or misaligned article causing activation of said lifting means thereby lifting said hood and said detecting means upwardly out of a path of travel of said downed or misaligned article.
Claim 15
Dependent Claim
126 words
A vertically movable hood positioned over a conveyor for transporting articles therethrough, said hood being connected to lifting means comprising a supporting frame member located at least partially above said hood, a support member affixed to said hood and to a portion and said frame member above said hood and adapted to impart vertical movement to said hood, and detecting means affixed to said hood in such manner as to sense a downed or misaligned article before said article reaches said hood, said detecting means being adapted to trigger an activating mechanism on contacting a downed or misaligned article causing activation of said lifting means thereby lifting said hood and said detecting means upwardly out of a path of travel of said downed or misaligned article.
Claim 16
Dependent Claim
48 words
The apparatus claimed in claim 13 in which said conveyor comprises a perforate belt member and a perforate channel member each communicating with distributor means sealingly positioned therebelow, said distributor means being adapted to deliver coating material upwardly through said conveyor to a coating area in said hood.
Claim 17
Dependent Claim
30 words
The apparatus claimed in claim 13 in which at least one side coating gun is affixed to said hood and adapted to deliver coating material into a coating area therein.
