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.
A method of mounting a flanged sink bowl in an opening in a counter top comprising attaching an angle-iron molding strip to the lower surface of said sink bowl flange, the portion of said molding attached to said lower surface having an inwardly directed marginal groove, placing said sink bowl in said opening in the counter top with flange and said portion of the strip attached thereto in engagement with the surface of said counter top proximate the opening and the other portion of said molding disposed within said opening, and holding said sink bowl in said opening by means of at least one clamp clip having a hooking end engaging said groove and a threaded fastener with an end engaged with the bottom surface of said counter top proximate said opening and arranged such that upon tightening of said threaded member said clamp clip engages and urges said other portion of said strip in a direction springingly urging the edge of said first portion and said sink bowl flange towards the top surface of said counter top.
