    Abstract: A clothes dryer employs a pivotally mounted resilient idler for tensioning a drive belt which is entrained about a pulley of the dryer drive motor and a rotatable dryer drum, the idler pivoting to a free position upon release of belt tension due to belt breakage or the like. A separable connector is serially connected in at least one power lead of the drive motor and associated with the idler to be separated and thereby to break the power circuit of the motor as the idler moves towards its free position.

    Abstract translation: 干衣机采用枢转安装的弹性惰轮，用于张紧驱动带，该驱动带被夹在干衣机驱动马达的滑轮和可旋转的干燥滚筒上，该惰轮在由于皮带断裂等释放带张力时枢转到自由位置 。 可分离连接器串联连接在驱动电动机的至少一个电源引线上并与惰轮相连以分离，从而当惰轮向其自由位置移动时，断开电动机的电源电路。
