  • Patent number: 4350117
    Abstract: A free stall construction for cattle is provided with open resting/feeding stalls. The stalls are separated by cantilevered tube members which are secured to the ground in the shoulder area of a reclining animal positioned in the stall. The tube members extend upward with increasing ground clearance and rearward with decreasing inclination from the shoulder area to an end area of the stall where a crossbeam rigidly connects the upper ends of the tubes at a height which does not hinder ingress or egress to the stall. Advantageously, the construction separates the cows, allows longitudinal movements in the stalls, provides stability and saves space.
