HOUSE, Royal Earl, inventor, born in Rockingham, Vermont, 9 September. 1814. He early became interested in mechanics, chemistry, and magnetism, and devoted much time to their study. The practicability of the printing telegraph became manifest to him, and he invented a keyboard, a single line of insulated electric Conductors, magnets, type wheels, automatic platens, and paper carriers, for several stations, adapted for transmitting and printing messages in Roman characters. This invention was first put in operation and exhibited at the Mechanics' institute, New York, in 1844. Although the first of its kind, it attained a speed of transmission of over fifty words a minute. Subsequently efforts were made by the representatives of the Morse patents to enjoin the use of the printing telegraph; but after much litigation Mr. House was sustained, he has since made other important inventions in the art of telegraphy.
