  • Patent number: 6698964
    Abstract: A connection assembly for constructing animal stalls including a connection body that is rigidly constructed and adapted for releasable and variable positioning upon an elongate support rail. A first releasable connector is formed in the connection body and is adapted for releasable fixation to an animal stall divider. The connection body is elongately constructed along a longitudinal axis with first and second ends that are distally located one from the other. The first releasable connector is positioned at the first end of the connection body. The connection body has first and second side flanges that are connected together by a webbing. At least a portion of the first and second side flanges project away from the webbing to form a receiving area between the portions of the first and second side flanges that is configured to insertibly accept a portion of an animal stall divider to be secured therein.

  • Patent number: 5975027
    Abstract: A method for configuring a livestock stanchion between various orientations. The method includes providing a livestock restraining stanchion having two upright members that define a stanchion opening therebetween and through which an animal's head is insertable. A pivotal restraining member is positioned within the stanchion opening and is adaptable for restricting the size of the opening for releasably restraining an animal therein by entrapping the animal's head after insertion therein. At least one of the upright members is inwardly and outwardly movable relative to the other and oppositely positioned upright member for expanding and constricting a width of the stanchion opening. In one configuration, the movable upright member is positioned away from the opposite upright member into an expanded configuration thereby enlarging the width of the stanchion opening.
