Abstract

8696. Johnson, F. G. L. April 6. Zeroizing - mechanism. -The type-wheels of a speed recorder of the periodic - counter type each carry four sets of type to facilitate zeroizing by means of a lever a<11> acting upon square bosses a<14> ; during zeroizing, the transfer pinions a<2> are thrown out of gear by an electro-magnet a<9> which depresses the lever and operates also a spring detent a<Î> to define the zero position.
