Patent number: 5488926Abstract: A livestock stand includes a platform having a perforated aluminum sheet upper supporting surface, a headrest assembly, and front and rear leg assemblies connected to the platform, each being pivotable between a first folded position and a second extended position. The headrest assembly includes a livestock headrest connected to a support arm which, in turn, is connected to the platform. Clamp assemblies are provided to permit the support arm to be adjustably positioned relative to the platform, as well as to permit the headrest to be adjustably positioned relative to the support arm. The clamp assemblies have a rigid envelope through which either the support arm or a mounting channel for the livestock headrest slide, and a clamp screw including a friction locking plug. Each leg assembly may be secured in its first and second positions utilizing a spring-loaded lock. The leg assemblies are vertically adjustable to raise and lower the level of the upper supporting surface of the platform.Type: GrantFiled: May 9, 1994Date of Patent: February 6, 1996Inventor: Roy H. Hunt

Patent number: 5411314Abstract: A foldable table is disclosed that comprises three basic parts (a table top assembly, a bench assembly, and four leg assemblies) interactively coupled to form a sturdy table that is easily folded or unfolded. The leg assemblies are spring biased to swing out to the unfolded position and the bench assembly rests on the leg assemblies by the engagement of bench stops on the bench assembly with notches on the leg assemblies. The table is securable in either the folded or unfolded position so that the legs will not unfold when in the folded position unless securing means are released and so that the table will remain fixed in the unfolded position unless securing means are released.Type: GrantFiled: November 2, 1993Date of Patent: May 2, 1995Inventor: Millard Wallace
