Abstract
Abstract The invention pertains to a resilient mounting used to mount electric motors in a motor housing on refrigeration units. The motor housing includes a plurality of spaced-apart recesses or openings on the periphery of the inner surface or face, while the electric motor includes a plurality of complementary spaced lugs also having recesses or openings formed therein, the motor and motor housing recesses when in the assembled position being opposite each other. Isolators formed of a rubber or rubberlike material fit into the complementary recesses on the motor housing and recesses in the lugs on the motor to yieldably and resiliently support the motor within the housing.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
148 words
In an appliance unit having a motor housing and an electric motor mounted in said motor housing, the improvement comprising: said motor housing having a plurality of spaced apart circular recesses therein on the interior surface facing said electric motor, a plurality of lugs also having recesses therein on said electric motor opposite to and in a complementary relationship to said circular recesses in said housing, and a plurality of resilient isolators having a center web segment with enlarged end portions at each end of said center web segment, wherein said enlarged end portions of each isolator fit into the complementary recesses on said motor housing and lugs on said electric motor to centrally suspend said electric motor within said motor housing to dampen noise of said appliance unit by the elimination of vibrations of said electric motor to said motor housing through resilient action of said isolators.
Claim 2
Dependent Claim
148 words
In an appliance unit having a motor housing and an electric motor mounted in said motor housing, the improvement comprising: said motor housing having a plurality of spaced apart circular recesses therein on the interior surface facing said electric motor, a plurality of lugs also having recesses therein on said electric motor opposite to and in a complementary relationship to said circular recesses in said housing, and a plurality of resilient isolators having a center web segment with enlarged end portions at each end of said center web segment, wherein said enlarged end portions of each isolator fit into the complementary recesses on said motor housing and lugs on said electric motor to centrally suspend said electric motor within said motor housing to dampen noise of said appliance unit by the elimination of vibrations of said electric motor to said motor housing through resilient action of said isolators.
Claim 3
Dependent Claim
243 words
In combination: a refrigeration unit having a freezer and food storage compartment; fan scroll means in communication with an evaporator compartment in said refrigeration unit and including a first outlet to direct air into the freezer compartment of said refrigeration unit, and a second outlet to direct air to the food storage compartment of said refrigeration unit; said fan scroll means having an integral motor housing; an electric motor within said motor housing; said electric motor having a radial vane impeller blower to direct air to the first and second outlets and secured thereto by means of an outboard drive shaft; wherein the improvement comprises: a plurality of spaced recesses on said motor housing; said spaced recesses being of generally circular configuration and extending the length of said housing; a plurality of complementary spaced lugs on said electric motor also having circular recesses therein opposite the recesses on said motor housing wherein said lug recesses extend the length of said electric motor; and a plurality of isolators having a thin center web segment between enlarged bulbous ends that fit into the circular openings on said motor housing and electric motor, and extend substantially the length of said electric motor, whereby said isolators suspend the electric motor centrally within said motor hOusing and yieldably isolate the motor housing from the electric motor to dampen noise of said refrigeration unit by dampening motor vibrations to the motor housing through the resilient action of said isolators.
Claim 4
Dependent Claim
243 words
In combination: a refrigeration unit having a freezer and food storage compartment; fan scroll means in communication with an evaporator compartment in said refrigeration unit and including a first outlet to direct air into the freezer compartment of said refrigeration unit, and a second outlet to direct air to the food storage compartment of said refrigeration unit; said fan scroll means having an integral motor housing; an electric motor within said motor housing; said electric motor having a radial vane impeller blower to direct air to the first and second outlets and secured thereto by means of an outboard drive shaft; wherein the improvement comprises: a plurality of spaced recesses on said motor housing; said spaced recesses being of generally circular configuration and extending the length of said housing; a plurality of complementary spaced lugs on said electric motor also having circular recesses therein opposite the recesses on said motor housing wherein said lug recesses extend the length of said electric motor; and a plurality of isolators having a thin center web segment between enlarged bulbous ends that fit into the circular openings on said motor housing and electric motor, and extend substantially the length of said electric motor, whereby said isolators suspend the electric motor centrally within said motor hOusing and yieldably isolate the motor housing from the electric motor to dampen noise of said refrigeration unit by dampening motor vibrations to the motor housing through the resilient action of said isolators.
Claim 5
Dependent Claim
17 words
In the invention as set forth in claim 1, wherein said isolators have enlarged bulbous end portions.
Claim 6
Dependent Claim
55 words
In the invention as set forth in claim 1, wherein said motor housing has at least three recesses therein, and wherein said motor has at least three complementary lugs thereon, with two of said recesses in said housing and two of said lugs on said motor being above the centerline of said housing and motor.
Claim 7
Dependent Claim
55 words
In the invention as set forth in claim 2, wherein said motor housing has at least three recesses therein, and wherein said motor has at least three complementary lugs thereon, with two of said recesses in said housing and two of said lugs on said motor being above the centerline of said housing and motor.
