ABSTRACT:
A clamp in the form of a generally L-shaped bracket or clip made preferably of a single stamping of spring steel or like material and provided with a threaded member, threading through the base of the bracket or clip. The top of the bracket or clip is provided with an angularly inwardly projecting integral portion terminating in a slightly downwardly bent flange forming a hook. The clamp is used principally for holding a sink bowl, or the like, in an opening in a counter top by cooperating with a generally L-shaped angle-iron strip welded to the underneath of the sink bowl flange. For removably holding the sink bowl in the opening in the counter top, the hook end of the clamp bracket body is engaged behind an inwardly bent flange portion of the angle-iron strip and the threaded member is tightened against the lower surface of the counter top proximate the opening. When the threaded member is tightened, the angle-iron strip and the sink bowl flange are drawn toward the top surface of the counter top while, simultaneously and due to the geometry of the clamp clip having its hook end non-aligned with the end of the threaded member and to the engagement of the back of the clamp clip with the inner surface of the angle-iron strip, fastening of the threaded member is amplified by leverage, thus greatly increasing the pressure holding the sink flange against the top surface of the counter top.
