Abstract
Abstract An adjustable support by which the distance at which a member is supported with respect to a base may be altered, is readily accessible for adjustment at a point remote from the supported member with respect to the base, and includes a junction with the supported member which is capable of limited universal movement to accommodate misalignment of the supported member with respect to the base.
