Abstract

441,863. Statistical machines. BRITISH TABULATING MACHINE CO., Ltd., Victoria House, Vernon Place, Southampton Row, London. July 25, 1934, No. 21807. Convention date, July 26, 1933. [Class 106 (i)] In a record-card-controlled statistical machine a plurality of feeding discs 251 are provided at the reading station which coact with the brushcontact roller 77 to feed the cards and which are located between the brushes 76 along the row of the latter. The brushes 76 are mounted in holders 252 in an insulating bar 216 and extend through the grooves 250 formed between the discs 251 into contact with the card, which is of thin cardboard or paper. The discs are preferably integral parts of an insulating roller 213.
