Title: Improvements in electrical signalling means
Filed: 1928-03-19
Abstract: 304,947. Electroflo Meters Co., Ltd., (Republic Flow Meters Co.). March 19, 1928. Tell-tale apparatus.-In an electric signalling system wherein indications are given of the position of an index or member operated according to the variations of a chemical or physical quantity by variation of resistance, a movable contact arm is periodically released from contact - with the resistance to allow it to swing freely into engagement with or under the control of the member. As shown in Fig. 1, the apparatus is applied to a gas analyzer wherein a bell 1 is raised to a height dependent upon the residual volume of a measured volume of gas. The bell carries a rod 4 provided with a helix 5 which co-operates with a slot in a toothed wheel 6 to convert the reciprocatory motion of the bell into a rotary motion. The rod 4 has an arm 9 which is adapted to co-operate with a pin 10 mounted on the pivoted contact arm 11 of a resistance 18 which is connected in circuit with indicating, recording or integrating instruments. The contact arm 11 has a spring brush 20 which is adapted to be moved into or out from engagement with the resistance by a pivoted bar 21 which is periodically raised by an arm 3. In operation when the bar 21 is raised the contact arm is allowed to swing freely into a position determined by the arm 9, and when the bar 21 is again lowered a resistance is included in the circuit which is dependent upon the height of the bell 1. If at the instant of measuring the arm 9 is not in engagement with the pin 10 the arm 11 is moved under spring control but if engagement has already occurred further movement of the bell 1 and arm 9 is permitted upon release of the arm 11 if the measuring movement of the bell is not complete. The rod 3 is periodically operated by auxiliary means associated with the gas analyzer and operates the bar 21 through the intermediary of an adjustable pin 23 and an interposed pivoted lever 24 which carries a mercury switch 26 adapted to break the circuit of the resistance 18 before release of the contact arm 11 and to again establish the circuit after the brush 20 is re-engaged. Zero adjustment of the arm 9 is effected by means of the pinion 7. The indicating instrument may be of the type described in Specification 272,594, [Class 37, Electricity, Measuring &c.], wherein the indicating pointer is operated by voltage and current coils both of which are controlled by the switch 26, and the moving system is so balanced that when the instrument is disconnected the pointer remains in its indicating position
