Abstract
Abstract An internal line break assembly for a hermetic compressor is assembled in two stages. A metal protector bracket is mounted to the stator as part of the mounting procedure for the stator. At a suitable later step a thermal protector in a protector mount is snapped into place whereby it is held in a spring biased relationship by the metal protector bracket.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
126 words
An internal line break assembly for a hermetic compressor comprising: a protector means for sensing the temperature of a motor winding and for cutting off electric power to the motor responsive thereto; a protector mount means having a recess formed therein for receiving said protector means; resiliently deformable bracket means coacting with said protector mount means having said protector means therein to bias said protector means into thermal contact with said motor winding; and said protector mount means further having a pair of diametrically extending ears each including a cylindrical portion and a flange portion with said cylindrical portions coacting with said bracket means in the nature of a wedge to cause said protector means to be held in biased thermal contract with said motor winding.
Claim 2
Dependent Claim
126 words

Claim 3
Dependent Claim
44 words
The internal line break assembly of claim 1 wherein said bracket means includes a spaced pair of spring clip risers each having a groove for receiving a corresponding one of said cylindrical portions and curved ends which together with said grooves make an ess.
