Abstract

313,748. Gunton, F. W. June 12, 1028. Winding-mechanism.-In automatic means for guiding tune-sheets, a pair of main ports 23, 26 so arranged in the tracker bar as to co-operate with the edges of normal tune-sheets, are connected directly to the interior of bellows 14, 15 which communicate with the exhaust 19 through bleed-holes 120, 121; a pair of auxiliary ports 27, 28 are reversely connected to recesses below diaphragms 31, 32 in an exhaust chamber 33, so that if the tune-sheet is so shrunk or creased as to expose both main ports, the direct connections 20, 24 are closed by smaller diaphragms 34, 35 which are forced up by spacers on the larger diaphragms 31, 32, the auxiliary ports then becoming effective. Specifications 9177/15 and 210,820 are referred to.
