Abstract
767,579. Variable resistors. PLESSEY CO., Ltd. Feb. 11, 1955 [Feb. 11, 1954], No. 4031/54. Class 37. A variable resistor comprises a base on which the resistive material is supported, a non-rotary shaft is mounted in the base and serves both as a terminal and mounting for the resistor assembly, a brush carrier engages with the shaft and an open-ended cover is held in contact with the base by means of the brush carrier, the cover and carrier rotating as a single unit. Figs. 4, 5 and 6 show a variable resistor comprising a resistive track 6, composed of compressed powdered resistive material and a thermo-setting binder which is mounted in a recess 5 of a moulded insulated base 1 on which are mounted terminals 7 connected to the ends of track 6. Base 1 supports a shaft 8 which passes through aperture 2 so that faces 9 abut against recess 3 and a groove 10 engages with the vertical slot 14 in a spring metal brush carrier 11 which is bowed so that the carbon brush 17 which it carries presses against track 6. The carrier 11 engages by means of slot 14, a key 20 in an open-ended cover or knob 18, the top of the carrier being sprung into the shallow recess 22 in cover 18 whilst the bottom of the limbs 13 passes through the slot 21. Variation of the resistance is effected by rotation of cover 18 and carrier 11 which rotate as one unit on shaft 8.
