Abstract

416,029. Recording particular operations. UNWIN, J. I., and UNWIN, R., Ashcroft, Chain Lane, Mickleover, near Derby. March 3, 1933, No. 6444. [Class 106 (iv).] Apparatus for recording data relating to telephone calls comprises a time-controlled drive for the record strip and a key or keys or equivalent devices for perforating, embossing or impressing type upon the strip one of the keys being adapted simultaneously to register the start of the call and to initiate the movement of the strip and one to register the termination of the call and stop the movement of the strip. The record strip 2 passes from a roll 3 over a clockwork-driven drum 1 to a roll 6 frictionally driven from the drum 1. The recording means comprise keys 19-25 formed as punches. The key 19 is depressed at the beginning of a call and punches a hole in the record strip and also removes a brake block 16 from contact with the milled part 1<b> of the drum. The drum then commences to rotate and is stopped at the end of the call by the depression of a key 20 which also punches the strip. Other data relating to the call are then recorded by the keys 21-25. The progress of time during the call is indicated by an arm 26 moving along a graduated slot 27<a> and having a one-way connection with the drum. After a predetermined interval a hammer 29 is released to strike a bell 28. The clockwork comprises a spring fixed at one end 1<a> to the drum and at the other end to a shaft 10 normally prevented from rotating by a pawl 15 acting through gearing 13, 14. A wheel 11 free on the shaft carries a pawl 11<a> engaging a ratchet wheel secured to the shaft 10. The wheel 11, which is thus stationary, gears with escapement mechanism 12 carried by the drum. The spring is wound by rotating the shaft 10 through the gearing 13, 14 and for this purpose the pawl 15 is disabled by a lever 15<a> and a pawl 15<c> is engaged with the periphery of the drum.
