Appl. No.:

12/655966

Inventors:

Larry G. Larson - Holmen WI, US
Patrick M. Hein - Viroqua WI, US
Glenn A. Klomsten - Trempealeau WI, US

International Classification:

A01J 7/00

US Classification:

119 141

Abstract:

A dairy milker unit detacher having a milker unit support arm that resists damage and breakage by incorporating a breakaway mechanism that disengages and then automatically or easily returns the support arm to a functional arrangement when a dairy animal or other force engages the support arm.

Appl. No.:

9/399623

Inventors:

Larry G. Larson - Holmen WI
Patrick M. Hein - LaCrosse WI
Robert G. Krause - Onalaska WI

Assignee:

Babson Bros. Co. - Naperville IL

International Classification:

A01J 504

US Classification:

119 1408

Abstract:

A milk machine detaching mechanism suitable for use in a sloping splash panel or other vertically limited space, having a pair of opposing components that can transfer load in the vertical direction, but which slide relative to one another in a lateral direction. The detacher is capable raising a milk machine support arm in a smooth and arc-shaped direction to avoid contact with a cow or a cow support platform as the support arm is being withdrawn. The detacher includes a folding arm assembly to minimize potential pinch points.

Appl. No.:

Inventors:

Larry G. Larson - Holmen WI

Assignee:

Babson Bros. Co. - Naperville IL

International Classification:

A01J 300

US Classification:

119 141

Abstract:

A support for positioning a milker unit beneath a cow has a shaft which is vertically movably mounted on a base. An arm on the shaft supports a milker unit beneath a cow. Air pressure is applied to the shaft to hold the shaft and arm at a desired vertical position. A control automatically adjusts the vertical position of the support so that when the milker unit is attached to a cow's teats the weight of the milker unit is applied solely to the cow's teats. The control includes a pair of valves each connected to a supply of air under pressure. A first of the valves has an open position in which the amount of pressure applied to the support decreases and the support is permitted to lower. A second of the valves has an open position in which air from the supply moves the first valve from a normally closed position to the open position thereof. The control has a lever mounted on the arm for moving the second valve to the open position thereof when the milker unit applies force to the lever.
