Abstract: 443,936. Variable - speed gearing. SMITH, A. F., 15, Church Road, Islington, and AGOSTINI, A. V., 26, Loddiges Road, Hackney, both in London. May 24, 1935, No. 15138. [Class 80 (ii)] Automatic variablespeed gearing comprises a flywheel 6 loose upon a driven crank - shaft 5 coaxial with a driving-disc 7. A crank-pin 10 of the shaft 5 supports loosely an intermediate member 9 which has a pin-and-slot or equivalent link connection 8 with the disc 7 and a like connection 11 with the flywheel 6. The inertial resistance of the flywheel 6 to periodic speed changes caused by the crank and the slot &c. connections effects that the member 9 exerts a driving moment upon the crank - pin 10. The shaft 5 is thus driven at a speed to suit the load. An arrangement is described with multiple cranks on the driven shaft supporting interconnected intermediate members the end ones having connections to the driving disc and to the loose flywheel respectively. An arrangement is described in which the cranks are replaced by eccentrics.

Terminal 16 of the potentiometer 14 may be coupled via a fixed resistor 19 to the positive supply terminal in order to prevent variable tapping 13 being moved up to the positive terminal of the supply voltage, the other terminal 15 of the potentiometer' being connected to earth. The fixed terminal 17 of the VDR on the potentiometer 14 is such that it is normally best for the user to adjust the tapping 13 to a position opposite it and thus it' may be desirable to provide the brightness knob with a mark indicating when tapping 13 is opposite terminal 17. The Specification includes' a detailed' discussion of the circuit operation. If the resistance of the portion between the terminals 15 and 17 of potentiometer 14.does not have a correct value a resistor 31, shown dotted, may be connected in parallel therewith, so that the resulting parallel combination has such a value that the desired voltage for 'the tube control grid is obtained at terminal 17. Resistor 31 may be made' variable so as to compensate for spreads in the' constants of various VDR's. To prevent tapping 13 attaining earth potential a further fixed resistor. may be connected between terminal 15 and earth. If the resistance of the portion between terminals 16 and 17 of the potentiometer is not correct resistor 19 may be altered. Specification 898,913 is referred to.
