  • Patent number: 4034505
    Abstract: A stand for an elongate upright object, such as a tree, including a fluid-holding receptacle into which the butt, or base, end of the object may be received, with a restraining device for engaging and holding the butt of the object against lateral movement in the receptacle. A cover for the receptacle has an opening extending therethrough to receive a portion of the object with screw adjustable engaging members mounted on one side of the opening. An elongate serrated wedge is slidably mounted on the top of the cover opposite the engaging members. The wedge may be slid into position frictionally engaging the object to hold it in place against the engaging members. Another opening in the cover is so positioned and of such size as to receive a support for the wedge on another cover to accommodate nested stacking of a plurality of the covers. A fluid barrier is removably mounted in the receptacle to prevent fluid in the receptacle from contacting the base of the object if desired.
