Title: Improvements in and relating to resetting mechanisms, more particularly suitable forelectric supply meters
IPC: G01R11/60
Filed: 1938-07-12
Abstract: 518,475. Indicating-apparatus. BRITISH SANGAMO CO., Ltd. (Sangamo Electric Co.). July 12, 1938, No. 20657. [Class 106 (iv)] [Also in Group XXXVI] A device for effecting the manual resetting by a return movement backwards to a given position of movable element such as the maximum demand pointer of an electric supply meter comprises a manually operable member rotatable through a complete revolution, a device for engaging the rotatable member to be reset, connecting means for interconnecting the manually operable member with the engaging device during the resetting operation, and means for automatically disconnecting the connecting means when the rotatable member has been restored to its correct position. Passing through the glass cover 21 of a supply meter is a shaft 25 having secured to its outer end a head 20,.in a slot in which is pivoted an operating arm 18. Normally this arm is secured by a seal in the slotted head of a stud 19. The shaft 25 is rotatable and also movable axially, being pressed downwardly by means of a spring 41. A pin 27 projecting from the head 20 rides on the upper surface of a cam collar 28 which is formed with a vertical notch and an inclined surface. A ratchet wheel 43 permits rotation of the shaft 25 in one direction only. At its inner end the shaft 25 carries a projecting pin 59 which, when the shaft is moved upwards owing to the pin 27 riding up the inclined surface of the cam 28, engages a pin 58 on a resetting finger 54. This carries a pin 56 which is arranged to engage the maximum demand pointer for restoring it to its zero position. The meter-reader disengages the operating-arm 18 from the stud 19, rotates it counter-clockwise for a complete revolution and then again inserts it in the notch and seals it. During this rotation of the shaft 25, the pin 56 engages the maximum demand pointer and returns it to the zero position, a spring 57 being stressed. At this point the pin 27 falls into the notch in the cam 28 and causes the pin 59 to disengage from the pin 58. The resetting finger 54 is thereupon returned by the 'spring 57 to its initial position as shown, which is beyond the maximum travel position of the maximum demand pointer and is determined by a stop 55. In order to provide a flexible connection between the resetting finger 54 and the pointer itself, the finger may be provided with a pin engaging the pointer and having limited movement against a spring with respect to the finger.
