Abstract: Controlled vertically swinging exit gates for milking parlor stalls having resilient control devices for lowering the gates in a smooth and controlled manner and to stop jerking downward or upward movement of the gate upon opening and closing, comprising two horizontally movable pulleys fastened to a draw-bar which actuates opposing cables to smoothly control operation of the gates.

Abstract: An improved milking parlor construction is provided for barns of limited floor space, comprising the combination of a modular unit which comprises a module which may be utilized in fabricating milking parlors of the type wherein a central pit area has juxtapositioned on either side a cattle stand wherein each of the modules is composed of at least two space-apart, hollow vertical upright members that may be supported in concrete or the like and from each of which a feed bowl and shroud may be hung. The feed bowl is provided with feed from a feed conveyor superpositioned over the hollow vertical upright member and in communication therewith. In order to accommodate limited floor space considerations, the module also includes at least a pair of vertically raisable gates attached to the vertical upright members. A mechanism is provided for raising and lowering at least pairs of gates.

Abstract: An improved milking parlor construction comprising the combination of a modular unit which comprises a module which may be utilized in fabricating milking parlors of the type wherein a central milking pit area has juxtapositioned on either side a cattle stand wherein each of the modules is composed of a vertical upright member that may be supported in concrete or the like and from which a feed bowl and shroud and individual cattle feeding station gate may be hung. Superpositioned over the vertical upright, which is of hollow construction, is a feed conveyor having communication to the vertical upright member which has a feed chute terminating in the feed bowl by which feed may be fed to the feed bowl of each of the cattle stations. Means are utilized whereby one or plurality of the gates defining a captive station at which the cattle are milked and, incidentally fed, provides easy egress for the cattle to the exit corridor to leave the milking parlor structure.

Abstract: In stanchion constructions of the type used in feeding lots and/or milking parlors, it is desirable to be able to control the cattle stations as by locking the cattle in captive positions or, alternatively, having the cattle stations remain open to permit free feeding and the like.The herein disclosed invention employs simple mechanical expedients, not requiring expensive forming techniques and having simple structure such as an elongate bar or rod with simple abutments formed, if desired, by through bolts and nuts to cooperate with a simple latching member to provide the captive position at the cattle stations.The elongate member is supported for linear and radial or rotational movement, so as to permit selective positioning of the pivotal members making up the cattle receiving stations in a simple, expedient manner, requiring little, if any, maintenance and construction sophistication.
