Abstract
Abstract A refrigeration condenser has the fan and motor supported in depending relation from an inverted, cup-shaped member centered in the top wall opening through which condenser air flows, the cup being supported from the perimeter of the opening in the top wall of the condenser housing by radial spokes having outer ends connected to the housing and extending in a substantially straight line inwardly to connections with the cup, so that the weight of the motor and fan is borne in part at least by tension in the spokes.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
147 words
A refrigeration condenser including: a housing containing a condenser coil and having side walls and a top wall, said top wall having an opening for the flow of condensing air therethrough; motor shield and support means in the center of said top wall opening; a vertical shaft fan motor having an enclosing shell, said shell being supported directly from said motor shield and support means; a fan secured to said motor shaft below said motor; and a series of radial spokes having their radially outer ends rigidly secured to said housing at the perimeter of said top wall opening and extending in a substantially straight line to said motor shield and support means with their radially inner ends rigidly secured to said motor shield and support means so that the weight of said motor and fan is borne in part at least by tension in said spokes.
Claim 2
Dependent Claim
147 words
A refrigeration condenser including: a housing containing a condenser coil and having side walls and a top wall, said top wall having an opening for the flow of condensing air therethrough; motor shield and support means in the center of said top wall opening; a vertical shaft fan motor having an enclosing shell, said shell being supported directly from said motor shield and support means; a fan secured to said motor shaft below said motor; and a series of radial spokes having their radially outer ends rigidly secured to said housing at the perimeter of said top wall opening and extending in a substantially straight line to said motor shield and support means with their radially inner ends rigidly secured to said motor shield and support means so that the weight of said motor and fan is borne in part at least by tension in said spokes.
Claim 3
Dependent Claim
24 words
A condenser according to claim 1 wherein: said motor shield and support means comprises an inverted, cup-shaped member having a downwardly directed perimetric flange.
Claim 4
Dependent Claim
86 words
A condenser according to claim 2 wherein: said motor includes opposite end bells and is of the open type having ventilating apertures in both end bells, and around the circumference of the motor shell adjacent each end; and said motor is carried by said cup by fastening means extending between the cup wall at least three of said apertures around the circumference at the upper end of said motor, whereby the apertures at the upper end of said motor are shielded by said cup from precipitation.
Claim 5
Dependent Claim
39 words
A refrigeration condenser according to claim 3 wherein: said fastening means includes plastic expanding grommets inserted in selected ones of said ventilation holes, and anchor screws connecting said cup to said grommets and expanding said grommets in said apertures.
Claim 6
Dependent Claim
139 words
A refrigeration condenser including: a housing containing a condenser coil, and having side walls and top wall, said top wall having an opening for the flow of air therethrough; a fan orifice ring depending from the perimeter of said top wall opening; an inverted cup-shaped member in the center of said top opening; a vertical shaft fan motor carried by said cup; a fan secured to said shaft below said motor and disposed in said orifice ring; and a series of generally horizontal radial spokes having their radially outer ends secured to said housing at the perimeter of said opening and extending in a substantially straight line to said cup-shaped member with their radially inner ends secured to said cup-shaped member whereby the weight of said cup, motor and fan is borne in part by tension in said spokes.
Claim 7
Dependent Claim
139 words
A refrigeration condenser including: a housing containing a condenser coil, and having side walls and top wall, said top wall having an opening for the flow of air therethrough; a fan orifice ring depending from the perimeter of said top wall opening; an inverted cup-shaped member in the center of said top opening; a vertical shaft fan motor carried by said cup; a fan secured to said shaft below said motor and disposed in said orifice ring; and a series of generally horizontal radial spokes having their radially outer ends secured to said housing at the perimeter of said opening and extending in a substantially straight line to said cup-shaped member with their radially inner ends secured to said cup-shaped member whereby the weight of said cup, motor and fan is borne in part by tension in said spokes.
Claim 8
Dependent Claim
69 words
A refrigeration condenser according to claim 5 wherein: said motor is of the open type having ventilating apertures in both ends and around the circumference adjacent both ends; and said motor is resiliently mounted from the rim of said cup-shaped member in inwardly spaced relation from said cup-shaped member and with the ventilating apertures at the upper end of said motor being shielded from weather by said cup-shaped member.
Claim 9
Dependent Claim
24 words
A refrigeration condenser according to claim 6 including: a motor wire conduit extending from said rim of said cup-shaped member to said orifice ring.
