Abstract

A milking claw includes a milk bowl with an interior having an inner bottom surface, an inner top surface and an inner sidewall surface between the inner top and bottom surfaces. Milk inlets are formed in the bowl and open into the interior of the bowl through the inner top surface and are connected to milk hoses leading to the teat cups. A hollow outlet tube is mounted to the bowl with an intake end spaced above and closely adjacent to the inner bottom surface of the bowl. The outlet tube extends upwardly and sidewardly from the intake end within the interior of the bowl, and extends through the inner sidewall surface to an exit end outside of the bowl. The outlet tube is preferably smoothly curved within the interior of the bowl so that milk is drawn out of the bowl with minimal turbulence and reduced vacuum pressure drop.

Claims

1. A milking claw comprising:

(a) a milking claw bowl with an interior having an inner bottom surface, an inner top surface, and an inner sidewall surface between the inner top and bottom surfaces;

(b) at least one milk inlet which opens into the interior of the bowl through the inner top surface of the bowl; and

(c) a hollow outlet tube mounted to the bowl with an intake end of the outlet tube spaced above and closely adjacent to the inner bottom surface of the bowl, the outlet tube extending upwardly and sidewardly within the interior of the bowl and joined to and extending through the inner sidewall surface to an exit end of the outlet tube that is located outside of the bowl.

2. The milking claw of claim 1 wherein the outlet tube extends upwardly and sidewardly from its intake end in a smooth curve.

3. The milking claw of claim 1 wherein there are four milk inlets opening into the interior of the bowl through the inner top surface of the bowl.

4. The milking claw of claim 3 wherein each inlet comprises a tube extending outwardly to a terminal opening and having an interior bore in communication with the interior of the bowl.

5. The milking claw of claim 1 including a hanger attached to the bowl above the inner top surface of the bowl.

6. The milking claw of claim 1 wherein the bowl has a cylindrical body with a cylindrical inner surface that includes the inner top surface, inner bottom surface, and the inner sidewall surface of the bowl, the cylindrical body having two circular open ends, and two circular windows mounted to the open ends of the cylindrical body to close the interior of the bowl.

7. The milking claw of claim 6 wherein the cylindrical body is formed of stainless steel and the windows are formed of transparent plastic.

8. The milking claw of claim 6 including a hanger attached to the bowl above the inner top surface of the bowl and wherein the intake end of the outlet tube is offset from the position at the inner bottom surface that is diametrically opposite the position at which the hanger is attached to the bowl.

9. The milking claw of claim 1 wherein the section of the outlet tube outside of the bowl is straight to allow thereby an unimpeded view of the interior bore of the outlet tube to the position at which the outlet tube is joined to the bowl.

10. A milking claw comprising:

(a) a milking claw bowl with an interior including an inner bottom surface, an inner top surface, and an inner sidewall surface between the inner top and bottom surfaces, the milking claw bowl including a cylindrical body having a cylindrical inner surface which includes the inner top surface, inner bottom surface and inner sidewall surface of the bowl, the cylindrical body having two circular open ends, and two circular windows mounted to the open ends of the cylindrical body to close the interior of the bowl;

(b) a plurality of inlet tubes mounted to the cylindrical body of the bowl and opening into the interior of the bowl through the inner top surface of the bowl; and

(c) a hollow outlet tube mounted to the cylindrical body of the bowl with an intake end spaced above and closely adjacent to the inner bottom surface of the bowl, the outlet tube extending upwardly and sidewardly within the interior of the bowl and joined to and extending through the inner sidewall surface to an exit end at a position outside the bowl.

11. The milking claw of claim 10 wherein the outlet tube extends upwardly and sidewardly from its intake end in a smooth curve.

12. The milking claw of claim 10 wherein there are four inlet tubes mounted to the cylindrical body and opening into the interior of the bowl through the inner top surface of the bowl.

13. The milking claw of claim 12 wherein each inlet tube extends outwardly to a terminal opening and has an interior bore in communication with the interior of the bowl.

14. The milking claw of claim 10 including a hanger attached to the bowl above the inner top surface of the bowl.

15. The milking claw of claim 10 wherein the cylindrical body is formed of stainless steel and the windows are formed of transparent plastic.

16. The milking claw of claim 10 including a hanger attached to the bowl above the inner top surface of the bowl and wherein the intake end of the outlet tube is offset from the position at the inner bottom surface that is diametrically opposite the position at which the hanger is attached to the bowl.

17. The milking claw of claim 10 wherein the section of the outlet tube outside of the bowl is straight to allow thereby an unimpeded view of the interior bore of the outlet tube to the position at which the outlet tube is joined to the bowl.
