Abstract

471,169. Statistical apparatus. SOC. INDUSTRIELLE D'INSTRUMENTS DE PRECISION. Nov. 25, 1935, No. 32599. Void. Convention date, Nov. 28, 1934. [Class 106 (i)] Perforated-card-controlled statistical apparatus has a selecting or line-finding device 3 for preparing the circuits leading to the sensing members corresponding to the work to be done by the bookkeeping machine 1, the finding device 3 being of the kind used in automatic telephone systems and being controlled by a special card 14. The device 3 has a contact 4 for each circuit 2 connected to the machine 1 and has a rotating contact 5 on a shaft 6. The latter also carries a ratchet wheel 7 which is driven by a pawl 9 and magnet 10 when feelers 12 read holes 15 in the special control card 14. The amount of rotation given to arm 5 and shaft 6 is stated to depend upon the position of the holes 15, on the number of teeth of wheel 7 and on the distance between pawl-arm 8 and, the magnet 10 in the non- attracted position.
