<p>1,123,910. Change speed gear. CROUZET S.r.l. 14 Oct., 1965 [6 Nov., 1964; 28 Nov., 1964], No. 43539/65. Heading F2D. [Also in Division H1] A variable speed gear mechanism for driving a time switch (see Division H1) from a motor 103 comprises a pinion 104 meshing permanently with three pinions 109, 113, 118 connectible by dog clutches, 109a, 113a, 118a with pinions 110, 114, 119 meshing permanently with a multi-diameter pinion 108. Clutches 113a and 118a are spring-urged to disengaged position, whilst clutch 109a is biased to energized position so that normally pinion 108 is driven via pinion 110. Clutches 113a, 118a, can be selectively engaged to transfer the drive to pinion 114 or 119 by rocking a lever 117 anti-clockwise or clockwise about its normal position shown in Fig. 17. The speed of the output pinion 107 may therefore have one of three values.</p> |
