Abstract

161,435. Worthington-Simpson, Ltd., and Hill, A. T. March 31, 1920. Cow-milkers.- A doublechambered teat cup comprises an annular flexible casing d, e forming the inner and outer walls of the cup, and maintained in its normal position by a spring i. The lower end of the casing is secured within a flanged cap a by means of a ring g and tapered screw-plug f, apertures h being formed in the ring g to transmit the pulsations of vacuum or pressure applied through the nipple c. The mouth of the cup is provided with an inturned lip l, which may be formed on a metal ring connecting separate inner and outer portions of the flexible casing, or, if the separate portions interlock together, the lip may be on the outer portion. A ring k of variable size or interchangeable with others of various sizes is employed to adjust the size of the mouth.
