1481674 Milking machines KUMMER ELECTRONICS BV 3 Dec 1975 [12 Dec 1974] 49737/75 Heading A1M In a milking machine having a teat cup cluster raised by a pneumatic piston-andcylinder arrangement on the cessation of milking, the pneumatic cylinder 1 is pivotally mounted on a vacuum line 16, and the control system for the cylinder includes an attitude sensitive switch 18 mounted on the cylinder. In order to apply the teat cups to a cow, an operator pivots the pneumatic cylinder to the chain-dotted position, thus actuating the switch 18 and thereby closing a valve 17 to cut off vacuum from 'the cylinder The teat cup cluster 6 lowers under gravity and may then be applied to a cow. When the milk flow falls below 2 litres per minute, a flow indicator 14 issues a signal opening the valve 17 thus supplying vacuum to the cylinder to raise the cluster.
