Abstract

865,221. Selective printing. INTERNATIONAL BUSINESS MACHINES CORPORATION. Dec. 16, 1957 [Dec. 28, 1956], No. 39033/57. Class 100(4) In a printing device wherein impression is made on a web 24 from a type member 10 whose type faces are continuously moving past the impression position, a hammer mechanism consists of a series of hammers 55, pivoted on a rotor 50, which hit the end of a firing pin 25 supported in a carrier 28 which is selectively operable to move the pin 25 into the path of one of the hammers. The device is used to print characters from electrical signals of an electronic computor. These signals are received over line 49 and cause operation of an electrostatic clutch 43-46 which, via linkage 41-36, pivots the carrier 28 from stop 33 to stop 34. One of the hammers 55, each of which has an effective mass equal to that of the firing pin 25, now engages the latter guided in a nylon bearing in the carrier 28. The rotor 50 is geared to the type member 10 so that impression is accurately aligned on the web 24. After impact the firing pin is restored by a wire spring 30; the hammers 55, which had been knocked clockwise by impact, return to rest against stops 57 under influence of centrifugal force.
