Abstract

867,145. Valves. MIDGLEY, A. H., and MIDGLEY, A. M. June 29, 1959 [July 8, 1958], No. 21863/58. Class 135. [Also in Group XXXVII] . The starting and stopping times of a switch similar to that of Specification 768,842 are set by a single member, which can also set the hands of a clock controlling the switch. A knob 34 is attached to a sleeve 32 carrying a pinion 35 which in its outer position (Fig. 3) engages a pinion 36 connected via gears 37, 38 with a pinion 29 controlling the hands 1, 2. If the knob is depressed (Fig. 5), pinion 35 meshes with a pinion 39 which via a gear 21 drives a gear 8 having a lost-motion connection with a gear 20. Gears 8, 20 are mounted on sleeves 44, 43 respectively carrying stop and start indicator discs 47, 10. Anti-clockwise rotation of knob 34 in the inner position rotates discs 10, 47 clockwise to set the start time, subsequent clockwise rotation of the knob returning disc 47 to set the stop time. Specification 846,398 also is referred to.
