Abstract: 544,750. Statistical apparatus. REMINGTON RAND, Inc. Dec. 7, 1940, No. 17408. Convention date, Dec. 21, 1939. [Class 106 (i)] A machine for handling master and detail record cards and including a comparing means, separate record conveying and deflector means for passing the records to their respective pockets, and a means operable under the control of the comparing means to operate both deflector means, is provided with a settable means to cause selective or concommitant operation of the deflector means. The invention is shown applied to the type of machine described in Specification 546,590 wherein the comparing mechanism slides 470, Fig. 1, co-operate with a bail 640 to control the operation of a ratchet mechanism comprising pawls 608, 618 on levers 610, 620 and ratchet wheels on a sleeve 600 carrying a number of individual control cams for varying machine functions. The sorting control cam 780 shown is engaged by a roller 781 on a bell crank 782 that is supported by a lever 784 settable to effective position by a manually adjustable disc 788. In accordance with the present invention the bell crank 782 carries a link 927 with a pin 926 arranged to contact the working faces of arms 924, 938 arranged on opposite sides of the link, Fig. 2A, and secured to a shaft 685 and sleeve 936 respectively, the shaft and sleeve being operatively connected through links 922, 934 to the master and detail deflectors 680, 690, Fig. 1A. When agreeing master cards and detail cards are sensed the roller 781 engages a low dwell on the cam 780 and the deflectors are held in the position shown to feed the cards to their respective receiving pockets 25, 27. When disagreement is sensed the sleeve 600 is operated to bring the high dwell on the cam on to the roller 781 thereby rocking the bell crank 782 and through the pin 926 and arms 924, 938 rocking the shaft and sleeve to displace the links 922, 934. The link 922 raises the deflector 680 during the following cycle to send the master card to the eject pocket 26. In the machine described the detail card requires an additional cycle to reach its receiving pocket so that the action of the deflector must be delayed. For this purpose the link 934 has a pin and slot connection with a latch 931 that engages a bell crank 930 to hold the deflector 690. A pin on the bell crank extends into a slot of a link 694 operatively connected to a cam follower 698. Movement of the link 934, with the link 922, merely tensions a spring 933. Near the end of the following cycle the link 694 is operated to rock the bell crank 930 and disengage the latch. The return of the link at the end of the cycle permits a spring 693 to rock the bell crank 930 to open the deflector 690 so that the disagreeing detail card passes in the following cycle into the eject pocket 28. Selective control of deflector mechanism.-To control the sorting of master cards only, detail cards only, or master and detail cards concommitantly, a control lever 900 is provided. The control lever is formed with a notched plate that co-operates with a detent lever 904, to hold the lever in an upper, intermediate, or lower position. An arm of the control lever has a pin engaging the forked end of a lever 908 connected by a link 910 to the link 927. The working faces of the arms 924, 938 are so proportioned that in the upper position of pin 926 it is aligned with the working face of lever 924 only to control the master card deflector; in the lower position of pin 926 the working face of the arm 938 only is operative to control the detail and deflector ; in the intermediate position both faces are operative. A selection, conversely to that described, may be effected by offsetting the control cam 780 through 45 degrees.
