ABSTRACT:
An improved kerf clamp for maintaining two sheet members in pre-disposed relation on either side of a kerf. The clamp is fabricated from sheet metal stock in such a way as to maximize strength and minimize material and production costs. The clamp includes a generally planar sheet metal base which is ribbed for added rigidity and includes an integral kerf blade which extends perpendicularly therefrom and has a stud screw extending axially from the distal end thereof. In use, the base is positioned underneath the sheet material to be clamped with the blade extending upwardly through a kerf cut therein. The clamp also includes a pressure part formed from sheet metal which is bent and shaped into a hollow tubular structure having a narrow upper gripping portion. A pair of sheet metal bulkhead-like inserts are mounted within the pressure part to impart rigidity and strength in compression. Aligned apertures through the top and bottom of the pressure part are adapted to receive the stud screw and kerf blade, respectively, when the pressure part is positioned on the upper surface of the sheet material. A wing nut on the upwardly protruding end of the base stud screw on tightening draws the base and pressure parts together thereby clamping the sheet material therebetween.
