Phonographs &c.-A permanent or adjustable bar bridge c fixed to the diaphragm chamber a carries a small wheel or bearing-surface d adapted to run upon the surface of the record disc or cylinder g parallel with the edge of the cutting-stylus, which is otherwise independent of it. In this way, the weight of the recorder is carried by the bridge, and the diaphragm is not subjected to undue strain.
