Mobile arrangement for a group stabling and handling of farm animals

A mobile arrangement for the confining stabling and treatment of a plurality of milk producing farm animals, comprising an enclosure with two similar rectangular bays disposed in mirror relationship, each bay having two sets of longitudinally extending rails, the sets of rails of each bay being parallel to and spaced from each other, the two sets of rails extending normal to the imaginary plane separating the two bays from an inner terminus adjacent such plane and an outer terminus removed from such plane, a milking room extending along said plane, a plurality of elongated platforms each having a plurality of confining stalls thereon extending transversely of the length of the platform, means for advancing the platform in each bay transversely of their lengths along a first set of longitudinally extending rails in a direction outwardly away from said plane to the outer terminus of the first set of rails, means for transferring the platforms in the direction of their length from the outer terminus of the first set of rails to the outer terminus of the second set of rails, means for advancing the thus transferred platforms in a direction transversely of their lengths along the second set of rails in the direction inwardly to the inner terminus of the second set of rails, and means for moving the platforms at the inner terminus of the second set of rails in the direction of their lengths to the milking room and thereafter transferring them to the inner terminus of the first set of rails, the platforms retaining the same orientation in space throughout their travel from the first terminus of the first set of rails to their return to said first terminus of the first set of rails.
