Title: Improvements in or relating to perforated record card controlled machines
IPC: G06K13/077
Filed: 1945-11-19
Abstract: 623,283. Statistical apparatus. BRITISH TABULATING MACHINE CO., Ltd. (International Business Machines Corporation). April 24, 1947, No. 11049. [Class 106 (i)] A card analysing device for a record card controlled machine comprises a movable frame (112, Fig. 9) carrying a plurality of flexible brushes (109) co-operating with contacts (189). The frame is mounted in such a manner as to prevent the brushes from digging into the card during movement of the frame. The mechanism described comprises a card magazine 25, Fig. 3, from which cards are fed by a picker 59 actuated through a linkage 61, 64, 65. The card 110 is passed by rollers 56, 58 to a " pre-sensing station " (see Fig. 4) where it is gripped by devices 82, 85 mounted on a frame 81R, 81L, which is reciprocated by a member 94, Fig. 1, oscillated about its pivot 98 by a slider 93 rotating with a shaft 50. In this manner the card is passed on to the " control station " where it is analysed by a battery of sensing brushes 109, Fig. 9, one for each data position on the card. The data represented on the card is transformed into timed electrical impulses through the medium of a rotating member 200 carrying contacts 205 spring-urged against the lower ends of the brush contacts 189. The card is accurately aligned at the sensing station by stops 101, 102, &c., which are given a suitable movement bringing them from below the plane of the card into contact with its leading and trailing edges as the grippers 83, 85, &c., are released and the frame 81R, 81L returns to its initial position. Grippers 83. 86 hold the card during its passage to the second sensing station where it controls the operations of adding and printing before being passed on to a known form of stacking device 74 which deposits it in a magazine 23. The sensing brushes are normally out of contact with the cards while the latter are being fed, the frame 111 holding them, being supported at 121, 123 by links 132, 133. The shafts 128, 130, supporting these links can move vertically relative to the frame 14, being secured to bellcrank levers 125, 127, pivoted at 124, 126 respectively and connected by a bar 137 which is given a reciprocating movement by a camactuated member 139. A horizontal movement is imparted to the frame 111 by a cam-actuated bell-crank 151, the upper end of which embraces a stud 153 on the frame 111. During sensing the card is clamped down by a pressure-plate 165 connected to bars 161, 162 attached to the frame 111 by screws 163 fitting in oval-shaped notches 164.
