  • Patent number: 6935270
    Abstract: A milking and applicator teat cup is configured to receive an animal teat within a liner located in a shell. At the openings of the liner and shell where the teat is received, there is an applicator configured to dispense disinfectant, conditioning, and/or cleaning solution to the animal teat. The applicator is designed to discharge the solution horizontally across the openings of the liner and the shell. Such a teat cup can be integrated into a milking system having a valve manifold coupled to a number of teat cups and controlling flow of milk from the number of teat cups and flow of fluid to the applicators, and a controller including logic configured to provide control signals to the valve manifold. The controller signals the valve manifold to pre-charge a hose or line delivering fluid to the applicator and signals the valve manifold for the end of milking and begin delivery of the fluid from the applicator.

  • Publication number: 20040050333
    Abstract: A modular milking parlor has a rigid frame on which the components of the milking parlor such as milking stations and cow control systems are mounted. The milking parlor frame includes a rectangular frame base and upright members extending upwardly from the frame base. The modular parlor can be conveniently shipped as a unit by attaching wheeled carriages to the frame of the modular parlor and elevating the milking parlor by operating jacks on the carriages attached to the wheels. The modular milking parlor as supported by the wheels may be rolled to a truck which transports the modular parlor to the installation site, and can be rolled on the wheels from the truck to the position at which the modular parlor is to be installed, at which point the carriage jacks are operated to drop the modular parlor on the ground, and the carriages are removed.

  • Patent number: 6543382
    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.

  • Patent number: 6298807
    Abstract: A barrel claw of increased volumetric capacity without sacrificing ergonomics has a normally horizontally disposed, elongated hollow body having a generally cylindrical central portion and a pair of tapered, conical end portions on opposite sides of the central portion. Viewing windows at opposite ends of the body permit observation of the internal chamber from outside the body. Inlet openings from the teat cups are provided in the top wall section of the body in the tapered end portions thereof so that the inlets are properly angled toward the teats of the cow's udder during use of the claw. An integrated discharge spout and pulsation manifold unit is removably attached to the top of the body in any one of a number of rotative positions so as to most advantageously position the radially projecting spout of the unit relative to the observation windows and other equipment associated with the milking system.
