  • Car coupling
    Patent number: 4073507
    Abstract: A mine car coupling device is described which comprises a coupling pin assembly pivotally mounted so that a pin is automatically engaged into the aperture of an elongated ring shaped receiving member or tongue. The housing has sloped front guide surfaces and curved inner side walls that align the coupling receiving member or tongue in both horizontal and vertical orientation so that the pin will be affirmatively engaged in position. The coupling receiving member permits horizontal and vertical variation of the tongue member through the use of compressible rubber springs.
