Abstract

336,258. Middle, W. H., and York, H. July 10, 1929. Cow-milkers. - The pulsator comprises a casing a. provided with a vacuum port f, an atmosphere port e and two ports b, c communicating with a nozzle d connected to the teat cups, the ports being controlled by a spring-loaded piston g operated by a cam h. In the position shown, the teat cups are subjected to suction tramsmitted through the port f, a groove k in the piston, and the port c, whereas when the piston rises, the suction port f is closed and air is admitted to the teat cups through the port e, groove k and the port b.
