(2.) In milking-apparatus of the kind set forth, a pulsating apparatus comprising a cylinder provided with two pairs of ports; and in which reciprocates a piston, either end of which is brought alternately under the influence of the vacuum in the vacuum reservoir, said piston having a recess adapted to put in communication when in one position a port leading from the vacuum reservoir and another leading from the vacuum-regulating device, and when in its other position to put into communication a port leading from the inspection device to the vacuum reservoir or milk-receptacle, substantially as described. (3.) The combination with pulsating apparatus for use in a milking-apparatus of the kind set forth of an oscillating disc valve having two recesses in its under face adapted to bring into communication with the passages leading to the cylinder-ends alternately a port in the valve-casing connected with the vacuum reservoir and a port leading to the atmosphere to produce reciprocation of the piston of said apparatus, substantially as described. (4.) For use in milking-apparatus, a teat-cup composed of a flexible collapsible sleeve to which is removably attached an inner sleeve having an inwardly projecting tubular portion extending within the outer sleeve and adapted to grip the cow’s teat, substantially as described.
