  • Patent number: 4226212
    Abstract: An animal holding gate operable either manually to hold an animal or automatically by contact with the gate of the animal to be held. The gate has a pair of upright animal engaging members supported on a main frame for movement toward and away from each other into or out of an engaging position within the traverse confines of the main frame. Movement of the animal engaging members is controlled by a pair of levers linked to a rotatable rock shaft that serves as one side of a guideway for the upper portions of the engaging members. A spring assembly is actuable to bias the rock shaft in a direction to move the engaging members, into an animal engaging position. A trigger assembly has a catch member on the rock shaft and a latch member on the main frame which are engageable to hold the rock shaft, against the force of the spring assembly, in a rotated position in which the animal engaging members are out of an animal engaging position.
