Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
166 words
In a motor of the refrigerator fan-type having a stator of a plurality of rectangularly shaped plates, the end plates of said plurality defining a first and a second plane and an operatively associated rotor modular assembly adjacent said first plane associated with a rotor and with a shaft extending from said second plane, the combination of: universal mounting means for mounting said motor in association with a refrigerator comprising a first pair of through holes through said plurality of plates along a lateral edge thereof; a second pair of through holes through said plurality of plates along an opposite lateral edge; at least a selected bracket member demountably received on said second plane and removable retaining means disposed in and through said through holes of each of said first and second pair of through holes for retaining said at least a selected bracket member in relatively rigid relationship with respect to said motor and for retaining said modular assembly in operative relationship with said stator.
Claim 2
Dependent Claim
166 words
In a motor of the refrigerator fan-type having a stator of a plurality of rectangularly shaped plates, the end plates of said plurality defining a first and a second plane and an operatively associated rotor modular assembly adjacent said first plane associated with a rotor and with a shaft extending from said second plane, the combination of: universal mounting means for mounting said motor in association with a refrigerator comprising a first pair of through holes through said plurality of plates along a lateral edge thereof; a second pair of through holes through said plurality of plates along an opposite lateral edge; at least a selected bracket member demountably received on said second plane and removable retaining means disposed in and through said through holes of each of said first and second pair of through holes for retaining said at least a selected bracket member in relatively rigid relationship with respect to said motor and for retaining said modular assembly in operative relationship with said stator.
Claim 3
Dependent Claim
31 words
The motor in accordance with claim 1 wherein each of the through holes of said first and second pairs of through holes are in vertical alignment with respect to one another.
Claim 4
Dependent Claim
33 words
The motor in accordance with claim 2 wherein the through holes of said first pair of through holes are in horizontal alignment with the through holes of said second pair of through holes.
Claim 5
Dependent Claim
17 words
The motor in accordance with claim 3 wherein said retaining means comprises through bolts and associated nuts.
Claim 6
Dependent Claim
29 words
The motor in accordance with claim 4 wherein said modular assembly is adapted to mount an additional selected bracket member to cooperate with the other of said bracket member.
Claim 7
Dependent Claim
31 words
The motor in accordance with claim 4 wherein said at least a selected bracket member is adapted to be associated with a supporting bracket of a refrigerator in secured relationship therewith.
Claim 8
Dependent Claim
44 words
The motor in accordance with claim 6 wherein said at least a selected bracket member comprises an elongate plate having a projecting stand off and two such brackets are mountable in side by side relationship with said extending shaft being intermediate said stand offs.
Claim 9
Dependent Claim
40 words
The motor in accordance with claim 7 wherein said stand offs have threaded bores to receive a triangular grommet-carrying member in secured relationship which spans said stand offs, with the shaft of said rotor extending through the spanning portion thereof.
Claim 10
Dependent Claim
68 words
The motor in accordance with claim 4 wherein said at least a bracket member comprises an elongate transverse bar having terminal depending portions, said depending portions having apertures therethrough by which said bracket is retained in a selected pair of horizontally aligned through holes, the intermediate portion of said bar having a horizontally extending tab for insertion into a retaining block associated with a refrigerator motor Fan housing.
Claim 11
Dependent Claim
54 words
The motor in accordance with claim 9 wherein an additional bracket member is mounted on said modular assembly and comprises an elongate plate member having apertures in the ends thereof said plate member spanning said modular assembly and being retained thereon by retaining screws and an intermediate horizontal extending tab for retaining block retention.
Claim 12
Dependent Claim
122 words
In a motor of the refrigerator fan-type having a stator of a plurality of rectangularly shaped plates, the end plates of said plurality defining a first and a second plane, and an operatively associated rotor modular assembly mounted on one plane and a shaft extending from the other plane; the combination of: mounting means for mounting said motor in association with a refrigerator comprising an elongated grommet-carrying member, a pair of stand-offs adapted to be removably retained on the plane from which the shaft extends in positions opposite each other and on different sides of said shaft, said grommet-carrying member being adapted to span and be removably retained on said stand-offs with the shaft extending through the spanning portion of said member.
Claim 13
Dependent Claim
122 words
In a motor of the refrigerator fan-type having a stator of a plurality of rectangularly shaped plates, the end plates of said plurality defining a first and a second plane, and an operatively associated rotor modular assembly mounted on one plane and a shaft extending from the other plane; the combination of: mounting means for mounting said motor in association with a refrigerator comprising an elongated grommet-carrying member, a pair of stand-offs adapted to be removably retained on the plane from which the shaft extends in positions opposite each other and on different sides of said shaft, said grommet-carrying member being adapted to span and be removably retained on said stand-offs with the shaft extending through the spanning portion of said member.
