Abstract

514,290. Calculating-apparatus. WEBB, C. F. May 28, 1938, No. 15978. Drawings to Specification. [Class 106 (i)] A calculating machine of the key-controlled multiple-bank type comprises a rack which is decelerated to substantially zero velocity in a comparatively gradual manner at the end of its operative stroke thereby bringing the figure wheel gently to rest in its correct position. The description agrees with that of Specification 514,291 but the claims differ. Specification 514,289 also is referred to.
