<p>The enclosure includes bottom and upstanding side walls with the gate at one end, one of the side walls having a pivoted panel forming a door for access within the enclosure. Wheels are carried by the enclosure and are pivotable between a first position rendering the enclosure transportable and a second out-of-the-way position rendering it immobile. The gate includes a pair of upstanding animal restraining members movable toward and away from one another by pantographic linkages connected to the side frames of the gate, the members being bowed outwardly intermediate their lengths. A lever is pivotably connected to the frame and to like ends of a pair of links which are in turn pivotably connected at their opposite ends to the restraining members. Swinging movement of the lever in opposite directions operates to move the members toward and away from one another whereby the members can be spaced selected distances one from the other. An upstanding arcuate rod is mounted on one side of the frame. The operating lever carries a locking bar which releasably frictionally engages the rod whereby the locking lever can be locked in selected positions thereby locating the members at a selected distance one from the other and also locking the members from movement in a direction away from one another.</p> |
