Abstract

819,962. Recording the working of machines. ATTWOOD, B. G. W. March 1, 1957 [Dec. 2, 1955; Jan. 12, 1956], Nos. 34552/55 and 1107/56. Class 106 (4). [Also in Group XXXVII] Apparatus for recording periods of use of electrical apparatus automatically so long as the apparatus consumes power has manuallyoperated .switches to start and stop at will the recording of an additional record which is also stopped automatically at the end of a period of use. The apparatus described in Specification 781,084 for recording the periods during which a receiver is switched on and also to which of a number of television transmitters the receiver is tuned during such periods is further provided with a switch pertaining to a particular person which he operates to cause a record to be made until either he operates the switch again or the receiver is switched off. In one embodiment the additional recorder operates when a switch 19 is closed by pressing a button 10 and continues to record while the switch is held closed by a solenoid 26 energized by the changeover of a linked switch 18, the record ceasing when button 11 is pressed to overcome the solenoid 26 or when current to solenoid 26 ceases upon the switching off of the receiver. In another embodiment the additional recorder operates when a switch 28 is closed by relay 22 energized by operating ON switch 20 and held by relayoperated switch 27, the record ceasing when current to relay 22 ceases upon operation of OFF switch 21 or when current ceases upon the switching off of the receiver. In each embodiment coloured lamps may indicate the condition of the apparatus.
