Abstract: A movable supporting device is disclosed for milking apparatus that includes a plurality of arms that are readily movable to position a claw during milking of a cow. A pair of spaced support arms are connected between vertically spaced pivots and the spaced arms have an angularly positioned spring therebetween. The two spaced arms are equal in length and joined to the pivots so that a pair of linking arms joined by an additional pivot are maintained horizontal regardless of the movement of the arms. In addition, a locking mechanism is shown connected adjacent to the vertically spaced pivots for locking the spaced arms in position when desired. A second pair of spaced support arms may also be utilized between the first pair of spaced arms and the linking arms. The milking claw is attached to the free end of the outer linking arm and since the device is movable in both horizontal and vertical axes, the claw can be readily moved as needed to facilitate milking of a cow.
