Title: Improvements in and relating to clutch control mechanisms
IPC: F16D67/02
Filed: 1929-12-31
Abstract: 345,965. Combinations of clutches with brakes. DAIMLER CO., Ltd., BARRY, R. C., and SIMPSON, C. M., Daimler Works, Coventry. Dec. 31, 1929, No. 39835. [Class 80 (ii).] Comprises clutch control mechanism of the kind having a clutch brake or stop adapted to retard or control the speed of rotation of the driving-shaft of the change-speed gear, characterized by the provision of means for adjusting the position of the clutch-brake shoe in relation to its clutch plate or stop on the driving-shaft, which means are adapted to be mounted on the gear-box and project through the footboard in a readily accessible position. In the construction shown, the clutch-pedal lever 1 pivoted at 3 carries a lug 4 to which is pivoted a link 5 connected at its other end by a swivelling eye-bolt 6 to an arm 7 fixed on a shaft 8. A bellcrank lever loosely mounted on the shaft 8 has one arm 18 carrying a brake shoe 19 adapted to engage a plate 13 on the driving-shaft 14 of the change-speed gear, and another arm 20 carrying a swivelling eye-bolt 21 through which passes freely one end of a screw 17 the other end of which screws into a swivelling eye-bolt 16 carried by an arm 15 fixed to the shaft 8. A spring 23 separates the arms 15, 20 until a collar 22 on the screw 17 bears against the eye-bolt 21. The screw 17 is rotated when desired by means of a hand-wheel 29 projecting above the floorboard 30, shaft 28, rotatable tube 26, and a flexible shaft 32. Thus by rotating the hand-wheel 29 the screw 17 is rotated and the angle between the arms 15, 20 is altered, so that the shoe 19 can be caused to engage the clutch plate or stop 13 at any desired part of the travel of the clutch pedal. The link 5 has a sliding connection with the eye-bolt 6 controlled by a spring 12 and adjusting-nuts 11, so that after the brake shoe 19 has engaged the clutch plate the pedal can continue its movement. The rotatable tube 26 and other parts are carried by a boss 25 on a plate 24 secured to the gear-box.

Title: Improvements in electronic means for stablising the speed of a time-piece motor
IPC: G04C3/10
Filed: 1962-10-26
Abstract: 1,011,550. Automatic speed control; clocks and watches. FABRIQUES MOVADO. Oct. 26, 1962 [Nov. 20, 1961], No. 40550/62. Headings G3R and G3T. A tuning-fork coupled to a transistor drive circuit stabilizes the speed of a small electric motor for e.g. a time-piece. The motor Fig. 1 (not shown) comprises a permanent magnet rotor, and a stator with an exciter coil Em and a pick-up Cm connected in the collector and base circuits respectively of the transistor Tm in an assisting sense to produce an accelerating torque. The exciter and pick of coils Er, Cr of the tuning fork are similarly connected to the same transistor, but in opposing sense, so that as the motor speed approaches the resonance frequency of the tuning fork and excites it to vibration the transistor drive is reduced. Capacitor Ca suppresses high frequency oscillation. By suitable design of the pick-up Cm it is possible to generate harmonics and so stabilize the motor speed at a half or a third of the resonance frequency of the tuning fork. To compensate for change in speed due to increased friction (e.g. from ageing of the lubricating oil) it is possible to increase the stabilised speed slightly by modifying the drive from the resonator control coil. Circuit modifications:- (i) Fig.4 (not shown), the resonator pickoff coil Cr is in the base circuit of a second transistor Ts sharing a common bias resistor R with the transistor Tm. When the resonator is excited Ts conducts to reduce the base voltage of Tm. (ii) The function of the resonator pick-off coil may be taken over the driving coil Er which may be tapped and is connected in series with the pick-up coil Cm in the base circuit of the transistor Tm, Figs. 6, 7, 8, (not shown).
