Abstract: A power-operated adjustable support means for carrying a milking apparatus at any one of a plurality of vertically related positions during a milking operation. A combination pneumatichydraulic control means is provided for adjusting the support, the control means including a double-acting piston and cylinder device with pneumatic pressure admitted to the cylinder on one side of the piston at a constant pressure and with hydraulic pressure admitted to the cylinder on the opposite side of the piston at a varying pressure greater than, less than or the same as the constant pneumatic pressure to effect reciprocating movement of the piston to adjust the support or to hold the piston at a desired position to maintain a given position for the support.

Abstract: A SUPPORTING MECHANISM FOR A MILKING APPARATUS WHICH INCLUDES A VERTICALLY ADJUSTABLE MEMBER HAVING A GENERALLY HORIZONTALLY DISPOSED ARM MEMBER MOUNTED THEREON, TE ARM HAVING A FREE END OPERATIVELY CONNECTED TO AND SUPPORTING A MILK RECEIVING RECEPTACLE BENEATH A COW. THE ARM IS OF A STRENGTH SUFFICIENT TO SUPPORT THE RECEPTACLE WHEN DISCONNECTED FROM THE COW''S TEATS. A LOOSE CONNECTION MEANS IS PROVIDED BETWEEN THE ARM AND THE ADJUSTABLE MEMBER TO PERMIT LIMITED VERTICAL MOVEMENT OF THE ARM RELATIVE TO THE MEMBER BETWEEN UPPER AND LOWER LIMIT POSITIONS WITH THE RECEPTACLE HANGING SUBSTANTIALLY BY GRAVITY FROM THE COW''S TEATS ONLY WHEN THE ARM IS BETWEEN THOSE POSITIONS. STOPS ARE PROVIDED TO PREVENT MOVEMENT OF THE ARM ABOVE THE UPPER LIMIT POSITION TO PREVENT THE TEAT CUPS OF THE MILKING APPARATUS FROM RIDING UP THE COW''S TEATS AND TO PREVENT MOVEMENT OF THE ARM BELOW THE LOWER LIMIT POSITION TO SUPPORT THE RECEPTACLE IF THE CUPS ARE DISCONNECTED FROM THE COW''S TEATS.
