    "The object of my invention is to increase the simplicity in construction and operation of the phonograph by decreasing the number with the objects of increased simplicity. . . . it consists in attaching both the recording-point and the reproducing point to the same diaphragm, and so arranging the parts carrying such diaphragm that by a simple movement either the recording or the reproducing point may be placed in operative position."--Thomas A. Edison. Filed with the United States Patent and Trademark Office December 19,1891.
