Abstract

437,618. Differential speedometers. BLEACHERS' ASSOCIATION, Ltd., Blackfriars House, Parsonage, Manchester, and OSTLER, P., 3, Howard Drive, Hale, Cheshire. May 3, 1934, No. 13347. [Class 106 (iii)] For indicating the slip between engaging rotating rollers 6, 7, used, for example, for feeding webs, each roller drives through a speed-increasing gear 8 an electric generator 9 connected to a differential voltmeter 12, the circuit being controlled by a switch 13 operated by a drive 14.
