Abstract
Abstract A rotary coupling for use in a milking parlor wherein the rotary coupling permits the carrying of fluids, and electricity, from stationary members to rotating members. The rotary coupling is used primarily with rotating milking parlors wherein the milking operation is performed as the cows move on a rotating platform. The rotary coupling permits the carrying of necessary power for the milking operation, and the return of milk from the rotating platform to the stationary milk building.

Claim 1
Independent Claim
324 words
A rotary coupling for rotating milkiNg parlors for carrying fluids and electric power from a stationary portion of the parlor to the rotating portion of the parlor, comprising a stationary member, a rotating member rotatably mounted with respect to said stationary member for rotation about a substantially central axis, means to support said rotary coupling with said central axis extending substantially vertically, said stationary and rotating members being concentrically mounted about said central axis, said stationary member comprising a housing defining a central opening and including a first section encompassing said rotating member and having a plurality of axially spaced, annular recesses defined therein, a plurality of conduits connected to said housing on the exterior of said first section, each conduit being open to one of said annular recesses, said conduits including at least one vacuum carrying conduit, and other conduits carrying fluid under pressure, separate passageways in said rotating member each aligning with one of said annular recesses in said first section of said stationary member, and said separate passageways in said rotating member including portions having axes substantially parallel to said central axis, means to couple said passageways in said rotating member to remote lines rotating with said rotating member, said rotating member having a central passageway extending completely through said rotating member, said coupling including a second portion for transmitting electrical power including electric annular slip rings on said rotating member and stationary brush means mounted on said housing, said annular slip rings and said brush means being postioned vertically above said first section of said housing carrying said annular recesses and said conduits, and seal means between each of the individual annular passageways in said stationary member and corresponding portions of said rotating member and passageway means in said rotating member for carrying electrical wires to said slip rings, said central passageway through said rotating member being a nonsealed passageway of size to permit a separate conduit to pass therethrough.
