Abstract
A clamping apparatus adapted to be clamped to a table top in a do-it-yourself home workshop comprising a C-shaped clamping element provided with a guiding ledge and an upwardly projecting stop, both of which serve to contact a workpiece at a right angle intersection of the ledge and stop. The apparatus is further provided with a U-shaped clamping element which, in conjunction with the C-shaped clamping element, serves to hold said workpiece in a desired fixed position. The U clamp comprises a U-shaped body portion and a threaded screw element with a centering head on one end thereof and a knob on the other end which engages a threaded aperture on one leg of the U clamp. A centrally located aperture in the upwardly projecting stop of the C clamp cooperates with the centering head to axially guide such centering head of the screw element of the U clamp to thereby encircle the workpiece.
