Abstract

894,517. Zeroizing-mechanism. TELEPHONE MANUFACTURING CO. Ltd. (Elmeg Elektomechanik G.m.b.H.). Sept. 11, 1959, No. 31056/59. Class 106 (1). In a counter in which the transfer pinions are disengaged from the numeral wheels for zeroizing, the numeral wheels are positively locked in zero position until after the transfer pinions have been re-engaged. To zeroize a counter including a numeral wheel 1, a zeroizing button is depressed, moving a lever 11 to the right, this movement being transmitted by a pin 14 to a lever 5 which moves towards the heart-shaped cam 2 on the numeral wheel. The friction produced by a spring 9 between the lever 5 and a pinion bridge 8 causes the pinions to be brought out of engagement, until the bridge 8 meets a stop 10, the pinions being locked by means not shown. On further movement of the lever 11, the lever 5 contacts the heart cam 2 and the wheel 1 is zeroized, pressure on the lever 11 continuing until the lever 5 has penetrated to the bottom of a depression 6 in the cam 2. When the zeroizing button is released, a spring 12 urges it to its original position, and with it the lever 5 and, through the friction of the spring 9, the pinion bridge 8. The depth of the depression 6 is such that only when the teeth of the transmission pinions 4 are already re-engaged, does the lever 5 unlock the numeral wheel by leaving the depression 6.
