Abstract

218,905. Richter, M. B. Nov. 7, 1923. Reciprocating and oscillating machines.-In a counter, primarily for registering telephone calls, an electromagnet 1 is furnished with a r -shaped pole-piece 3 extending down one end of the casing and along the top and with a pole-shoe 6 which at each energization attracts an armature plate 5 loosely supported by pins 10 and pivoting about an edge 9 formed by chamfering the upper portion of the plate. A flexible wire rod, anchored at its centre, engages the plate by both ends to return it to normal position, shown in Fig. 6. The plate carries at its lower end a pawl 22 to drive a ratchet wheel 23 fixed on a shaft 24 and bearing numerals visible through a window 48.
