Abstract

1469660 Grinding LITTON INDUSTRIES Inc 28 May 1974 [31 May 1973] 2641/75 Divided out of 1469658 Heading B3D The subject matter of the present Specification is identical with that of Specification 1,469,658 but the main claim is directed to a grinding machine having a rotatable member driven by power transmission chain means engaging a portion of a sprocket wheel on the member in first or second directions, at least one of the teeth of the sprocket being cut, and means for stopping rotation of the member at a predetermined orientation comprising first and second proximity switches for detecting the teeth which have not been cut, and means for operating the machine so that in a first mode, when the member is rotating in a first direction, the first and second switches are sequentially actuated to terminate rotation of the member and in a second mode, when the member is rotating in a second direction, the second and first switches are sequentially actuated to terminate rotation of the member.
