Abstract

471,015. Recording-apparatus ; barographs. BIRCHALL, H. J., and DIXEY & SON, Ltd., C. W. Oct. 20, 1936, No. 31371 /35. [Classes 106 (ii) and 106 (iv)] A record strip is wound from a storage roller 7 over guide rollers 9, behind a window 13, round driving rollers 10, 11, and on to a take-up roller 8. The roller 10 is driven around a fixed axis by a motor 14 and has spikes on its surface which penetrate through the record strip and enter the rubbercovered roller 11, this latter being carried in arms 17 pivoted at 18 and pulled by springs 19. The take-up roller 8, Fig. 4, is driven from, the roller 11 by a chain 21 and slipping coupling 27. The driven plate 25 of the coupling is provided with a projection 26 fitting into a recess in the roller 8, the roller being held in position by a spring 30. The record strip is not graduated, a scale being provided on the glass window 13. The glass is adjustable horizontally in guides by a knob 38 so that allowance can be made for variations in the length of the strip due to humidity. When the record is to be read, a lamp behind the strip is lit by depressing a switch 39. The invention is applied to a barograph, aneroid mechanism 31 actuating the recording pen 32.
