The rocking pressure described serves to keep the terminal edge of the jaw F5 from engaging the bottom edge face of the slot and deforming the jaw or slot or 4 shoulder “5 as a fulcrum, but the pair of lateral stops I3 resist any such tendency. Despite these advantageous functions of the stops it’, they are not essential.
