An infrared light sensor outside the milk flow path is connected with an end of milking indicator. The light sensor is connected with a milk flow detector which actuates the indicator giving a visual or audible signal when milk flow ceases. Vacuum is shut off and the milker is retracted. Electrical power for the light source, light sensor and indicator circuit is derived from the milker pulsator signals.

Optical milk flow detector and vacuum shutoff for milker

A method of milking is disclosed for a double action milking system having teat cups which alternate time periods of release and squeeze of the teat to allow milk to flow and to provide for rest respectively. Milking is initiated at one ratio of milk period to rest period and then increased to a selected higher ratio. Milking is then done at the selected higher ratio for a selected segment of time or until the milk flow rate falls below a predetermined value, after which the ratio is decreased so that milking is completed at a lower ratio.

Method of milking

A support structure for an arm adjustably supporting a hose at a stall of a cow milking system is disclosed. The structure includes a leg carried by a ball and having a tubular section within which the arm may be adjustably secured. The ball is received in a bracket permitting universal rotation with respect to the stall, the bracket frictionally securing the ball in whatever position it is placed. The arm may be moved manually or may be moved automatically by a retractor cylinder activated upon the completion of milking.
