Abstract

495,347. Automatic exchange switches; intermittent gearing. TELEFONAKTIEBOLAGET L. M. ERICSSON. Oct. 18, 1937, No. 28343. Convention date, Oct. 20, 1936. [Class 40 (iv)] [Also in Group XXIV] In a motor-driven selector, the substantiallyconstant velocity of the motor is converted into an intermittent movement to drive the wipers rapidly between contacts and slowly over them by means of a pair of pins P<1>, p<2> diametrically mounted on a motor-driven shaft A and engaging with the teeth of a longitudinal rack BK carrying the wipers. The Specification as open to inspection under Sect. 91 comprises also a statement (Claim 3) that the teeth on the rack may have cycloidal limiting surfaces. This subjectmatter does not appear in the Specification as accepted.
