Patent GB-518728-A (GB)
Abstract: 518,728. Galvanometers. ELLIS, F. C. Aug. 29, 1938, No. 25316. [Class 37] The moving - coil of a suspension - type galvanometer is automatically raised from its suspension and clamped in position when the meter is lifted, and separate manually operated means are also provided whereby the moving- coil may be raised and clamped at any time without lifting the meter. Preferably, the clamping means has to be released by operation of the manual control irrespective of its manner of operation. The permanent magnet 24 is screwed to bosses on the casing, and the moving- coil 30 is suspended by an element 32 secured to a rod 54 which may be both vertically and rotatably adjusted by a knurled head 56, By manual rotation of a knob 108, Fig. 6, a shaft 104 may be turned from one to another position as determined by spring biassed detents. A cam 102 turns with the shaft 104 and permits a spring 100 to rock the lever 96 whereby the ring 94 lifts the moving-coil 30 and clamps it between the rings 88, 94. The shaft 104 is also connected by an arm 126, Fig. 8, through a pin and slot connection 130 to a weighted plunger 134 which normally rests on the surface supporting the galvanometer, so that if the galvanometer is lifted the weight rotates the arm 126 whereby the moving system is clamped as described above. When the galvanometer is replaced on a supporting surface, the moving system remains locked and has to be released by reverse rotation of the shaft 104 through the manual control knob 108. In another arrangement, Figs. 9 and 10 (not shown), one of the supporting feet 12 comprises a spring biassed plunger which is moved by the sprng when the meter is lifted and rotates the shaft 104 to clamp the moving-coil through a lost-motion and rack and pinion device. Specification 520,926 is referred to.
