768,926. Couplings. ACF INDUSTRIES, Inc. May 3, 1955, No. 12767/55. Class 103(5) A coupling for vehicles of the type in which one end of one vehicle is supported by the adjacent end of another vehicle comprises a male member M having a longitudinally rotatable coupling tongue 21 and a pair of weightsupporting. stems 24 which enter complementary recesses -in the female member F. The tongue 21 has a recess 46 engageable by the latch portion 44 of a locking member 41 pivoted on trunnions 51 and operated by the crank 58. Torsion springs 61 on the crank 58 rotate the locking member 41 counterclockwise so that the latch 44 partly enters the recess 46 on initial coupling but the crank 58 is subsequently rotated by hand so that the complementary wedge surfaces on the tongue and latch draw the tongue further into the member F against the compression of rubber buffers 55, Fig. 2, between the members. Relative rotational movement between the vehicles is accommodated by the resilient bushes 16, 17 around the male member support pin 13 and by resilient bushes 35 releasably secured in the member F and surrounding the pins 24. Arrangements are described in which the male member is universally pivoted to the vehicle, the female member is pivoted on a horizontal transverse axis to the vehicle, and the tongue is universally jointed or resiliently mounted on the male member.
