Abstract: A milking unit support and detacher mechanism including a vertical column assembly and a horizontally extending retractable milker unit support assembly mounted at the lower end of the column assembly. The vertical column assembly is comprised of an outer tubular jacket and an inner support tube slidably mounted inside the jacket. The inner support tube is supported for vertical movement by means of a threaded rod, the upper end of which is supported from and drivingly connected to motor gear box unit. The lower end of the rod is threaded through an internally threaded collar secured to the top of the support tube. The retractable milker unit support assembly is comprised of four link members pivotally connected together in end-to-end relationship. The link assembly is retracted by means of a ball chain fastened at one end to the end link member and threaded back through openings in the two link members next adjacent the end link member. The other end of the chain link is connected to rotatably mounted hub member. The ball chain is reeled up on the hub by a motor drive to thereby cause the link members to fold up on themselves which in turn will cause the milker unit to be retracted from underneath the cow.
