Sorting machine

Abstract

Abstract 243,364. British Tabulating Machine Co., Ltd., (Assignees of Bryce, J. W.). Nov. 20, 1924, [Convention date]. Compiling statistics.-In a sorting machine for Hollerith cards read in motion there is a sorting brush at each station or deflector, the stations being one card cycle apart. The cards are fed with the " 9s " first under each brush; the main brush circuits are momentarily made live by the usual cam contacts 119 when the cards are simultaneously in their correct reading positions and in these positions at the first station the brush rests upon the " 9 " perforation index point, at' the second station upon the " 8 " point, at the third station at the " 7 " point and so on. Thus a card will only permit contact through its perforation while the main brush circuit is live when the card is at the correct sorting station. This energizes a magnet 107 which attracts its armature 111 and raises the deflector 108. At the same time the armature closes contacts 113 to complete a holding circuit 121 which is broken at' the correct moment by cam 120. The brushes are individually adjusted transversely of the machine to any card column. The construction of the sorting boxes, card-feed conveyer rollers and card-feed picker-blade mechanism are as described in Specification 242,654.
