Abstract

211,920. Waller, P. H. Nov. 3, 1922. Counting-apparatus.-In indicating, recording, regulating, and like apparatus operated by an impact or contact device capable of oscillating, such as printing-machinery of the flat-bed type, an electrical system is interposed between the impact device and the indicating or like component so as to render the oscillations, after the first, ineffective on the indicator or the like. Fig. 1 shows an oscillating contact lever 1 which is movable about its pivot to cause the contact arms 3, 4 to close the contacts 15, 25 according to the direction of movement. Restoration of the contact arms 3, 4 by the springs 5, 6 is delayed by the rotating-mechanisms 12, 13. The arms 3, 4 respectively control contacts in the circuits to the coils 22, 30 through contacts 19, 28 which are opened when the other coil is energized. The cores of the two coils control the step-by-step rotation of counting-mechanisms on a shaft 38, through one-way ratchets, and their return movement is retarded by mechanisms 33, 35. Thus, if the lever 1 swings back so far as to cause the closing of the contacts 25, the circuit to the coil 30 is open at the contact 28 and the core of the coil 30 is not moved. A roller detent entering a notch 44 is the counterweighted end of the lever 1 serves to hold the lever in normal position.
