Electromotograph

It will be understood, of course, that the electromotograph is a receiving and relaying instrument. ❋ Unknown (1910)

The principle of the electromotograph was utilized by Edison in more ways than one, first of all in telegraphy at this juncture. ❋ Unknown (1910)

Another notable use of the electromotograph principle was in its adaptation to the receiver in Edison's loud-speaking telephone, on which United States Patent No. 221,957 was issued November 25, 1879. ❋ Unknown (1910)

The electromotograph is shown diagrammatically in Figs. 1 and 2, in plan and vertical section respectively. ❋ Unknown (1910)

These electrostatic impulses are transmitted inductively to the elevated condensing surface at the distant point, and are made audible by the electromotograph connected in the ground circuit with such distant condensing surface. '' ❋ Unknown (1910)

It should be stated that Edison did not confine himself to the working of the electromotograph by the slipping of surfaces through the action of incoming current, but by varying the character of the surfaces in contact the frictional effect might be intensified by ❋ Unknown (1910)

For receiving signals I locate in said circuit between the condensing surface and the ground a diaphragm sounder, which is preferably one of my electromotograph telephone receivers. ❋ Unknown (1910)

Edison's electromotograph comprised an ingeniously arranged apparatus in which two surfaces, normally in contact with each other, were caused to alternately adhere by friction or slip by reason of electrochemical decomposition. ❋ Unknown (1910)

It should be stated that Edison did not confine himself to the working of the electromotograph by the slipping of surfaces through the action of incoming current, but by varying the character of the surfaces in contact the frictional effect might be intensified by the electrical current. ❋ Frank Lewis Dyer (1905)

This instrument was called the 'electromotograph,' and it occurred to ❋ John Munro (1889)

Moreover, it is not unlikely that the slipping of the stylus in the electromotograph is due to a similar cause. ❋ John Munro (1889)
