Clamping apparatus for providing a fixed support on a fixed beam or other similar structures wherein outer and inner elongated members are mounted for relative sliding telescoping movement therebetween and are moved by a rotatable threaded bolt and each of the outer and inner elongated members have an inclined surface so that when the inclined surface of the jaws contact the opposite side edges of the fixed beam the facing surfaces of the fixed beam and the outer and inner elongated members are moved into intimate contact.

[ What is claimed is:] [1.] Clamping apparatus for mounting on a fixed support having opposite side edges comprising:an outer elongated member having longitudinal axis;an inner elongated member having a longitudinal axis;at least a portion of said inner elongated member mounted inside of at least a portion of said outer elongated member to provide for relative sliding movement therebetween;an elongated threaded bolt mounted within said outer elongated member for rotational movement around a fixed axis;apparatus for rotating said elongated threaded bolt;a threaded nut mounted at a fixed location within said outer elongated member and in threaded engagement with said elongated threaded bolt so that rotational movement of said elongated threaded bolt provides said relative sliding movement between said outer and inner elongated members;a first jaw secured to said outer member for movement therewith;said first jaw having an inclined surface located to be moved into contact with one said opposite side edges;a second jaw secured to said inner elongated member;said second jaw having an inclined surface located to be moved into contact with the other of said opposite side edges;said outer elongated member having an outer surface facing a surface of said support so that, when said inclined surfaces of said first and second jaws are moved into contact with said opposite side edges, further rotation of said elongated threaded bolt forces said outer elongated surface of said outer member and said surface of said support into intimate contact; andsaid inner elongated member having at least another portion having an outer surface located substantially in the same plane as said outer surface of said outer elongated member so that said outer surface of said at least another portion of said inner member is also forced into intimate contact with another portion of said surface of said support.
