I claim as my invention— 1. The pulsator, acting to make and breakthe circuit to the printing-magnet I, in combi-nation with the arm 15, electro-magnet t, andconnections for arresting the pulsator simulta-neously with the stopping of the type-wheel, substantially as set forth. 2. An electric circuit closed by the contactof the revolving arm 15 with the finger-keystop 14, in combination with the type-wheeland actuating mechanism, substantially asset forth. 3. The arm 19, moved by the escapement-lever on, and acting to close the circuit to theprinting-magnet q, in combination with thepulsator g, magnet t, and circuits, substantial-ly as set forth.

THOMAS A. EDISON, OF NEWARK, NEW JEESET.IMPROVEMENT IN PRINTING-TELEGRAPH INSTRUMENTS. Specification forming part of Letters Patent No. 131, 341, dated September 17, 1872. To all loliom it may concern: Be it known that I, Thomas A. Edison, ofNewark, in the county of Essex and State ofNew Jersey, have invented an Improvementin Printing-Telegraphs, and the following isdeclared to be a correct description of thesame. Before my present invention the printing-lever magnet had been placed in the same cir-cuit as the type-wheel magnet, and the formerhad been i^revented from giving an impressioneach pulsation by a spring acting upon theprinting-lever; but unless the pulsations thatset the type-wheel lever were very rapid, theprinting-lever would be moved more or less.If the spring is under considerable tension, soas to prevent an impression until a pause oc-curs after the type-wheel has
