The milk claw has a frusto-conical cover fitting on and oriented to the bowl. The four inlets to the cover are downwardly and tangentially arranged on the cover so incoming milk hugs the inside wall of the cover as it swirls around the cover for discharge into the bowl. The bowl has a downwardly spiraled path leading to the outlet arranged on a radius of the bowl. A dam separates the start of the spiral path in the bowl from the outlet and serves to prevent the flow at the outlet from interfering with the flow entering the bowl.

1. A milking claw having a bowl and a cover meeting at a generally circular connection, said cover having a frusto-conical shape with the lower, larger diameter portion connected to said bowl, four inlet nipples connected to the upper side wall of said cover, each inlet nipple extending upwardly and outwardly from the sloping side wall of the cover generally tangential to said side wall so the incoming milk is downwardly directed and introduced to the interior of the cover in a tangential manner and swirls down and around the sloping inside of said cover on a path having an increasing diameter causing the milk velocity to decrease, and an outlet from said bowl positioned below said inlet nipples and receiving the milk after its velocity has decreased, any tendency of the milk to flow back to said nipples from said outlet requiring lifting and accelerating the milk. 2. A milking claw according to claim 1 in which said bowl is generally circular in plan view and said outlet is approximately on an extended radius of the bowl, the bottom of said bowl being shaped to provide a downwardly inclined spiral flow path, said spiral flow path leading from a high point at one end of said spiral flow path to a low point at said outlet and continuing the downwardly swirling flow of milk from said cover, said high and low points being circumferentially adjacent. 3. A milking claw according to claim 2 including a dam originating approximately at the center of said bowl and curving outwardly to a straight portion generally parallel to said extended radius, said dam being between and separating the start of said downwardly inclined spiral flow path in said bowl from said outlet. 4. A milking claw according to claim 3 in which said inlet nipples are paired with the nipples of a pair being closer to each other than they are to the nipples of the other pair and the outer ends of the nipples lie in a common plane and are arranged in a rectangle having long and short sides.
