464,445. Recording - apparatus. GLOVER & CO., Ltd., T., and WILSON, J. S. Oct. 29, 1935, Nos. 29827/35 and 2683/36. [Class 106 (iv)] Recording-apparatus combined with a gas meter comprises meter-driven means for advancing a record strip and a clock-driven punch or other marker which marks the strip at a time or times determined by the setting of a member on a clock-driven dial. In a modification, the punch is also moved slowly by clockwork laterally across the record strip. An arm 23, Fig. 1, is rotated about its axis 21a by the gas-meter mechanism and is connected by gearing 21, 19, to a shaft 2 carrying two discs 2a having teeth which engage perforations in the paper strip and thus feed it from a supply roll 3a to a take-up roll 4a. The take-up roll 4a is driven from the shaft 2 through gearing including a slipping coupling. The rolls 3a, 4a are mounted in slots 1b and held by catches 1c so that they can readily be removed. Clockwork mechanism 25, Fig. 3, causes a disc 25a to rotate once in twenty-four hours. A trip member 28, Fig. 1, is settable on the disc 25a so that at any predetermined time it engages the end 26d, Fig. 6, of a lever 26 and swings the lever clockwise to release a pin 30a on a pinion 30 gearing with a pinion 29a on a shaft 29 which is then driven through one revolution by the clock spring. A cam 2 thus oscillates the depending end 33, Fig. 3, of a lever 31 to depress a punch.36 against the action of a spring 37 to punch the paper strip. In the modification, Figs. 9 and 10 the shaft 2 is similarly driven from the meter mechanism and carries a drum 2d having teeth 2b which feed the paper strip from the supply roll 3a to the take-up roll 4a, the latter roll being driven from the shaft 2 by a spring belt 41. A shaft 47 is driven through one revolution at any predetermined moment by the means described in connection with the form shown in Figs. 1-6. A long cam 47a is mounted on the shaft 47 and thus actuates the punch 36. The punch is mounted in a carriage 51 supported on shafts 48, 49, the former 48 of which is screwed to engage a nut in the carriage and is driven from the clockdriven disc 25b through a spring coupling 50a. The punch is thus slowly moved across the paper strip to produce a record as shown in Fig. 14. The carriage is adjusted to any desired position by a hand wheel 48a on the end of the shaft 48.
