Abstract

929,445. Maximum demand meters. CHAMBERLAIN & HOOKHAM Ltd. Jan. 24, 1962 [Feb. 2, 1961], No. 3943/61. Class 106 (3). A maximum demand meter comprises a spirally-wound spring 10 one end of which is connected to an intermittently rotatable toothed wheel 11 which periodically causes re-setting of a pointer driving member, the other end of the spring 10 is connected to a ratchet wheel 24 for re-winding the spring, a looking lever 22 inhibits re-winding after the wheel 24 has turned through a predetermined angle and when the wheel 11 has turned through a predetermined angle a star wheel 17 releases the lever 22 to allow a further re-winding operation. A solenoid 14 periodically causes a lever 13 of an escapement mechanism to release the wheel 11 for rotation through half a revolution to drive a pinion 15 in the re-setting mechanism. In each revolution of the wheel 11 a tooth 16 advances a star wheel 17 one tooth and after five revolutions corresponding to ten re-setting operations, a pin 18 on one tooth of wheel 17 engages a pin 19 on a tooth of another star wheel 20. The wheel 20 turns with it a cam 21 so that the lever 22 escapes from the recess in the cam 21 and frees the pawl carrying arm for oscillation by cam 25 so that the pawl 23 drives the ratchet wheel 24 to wind the spring 10. Specification 929,444 is referred to.
