Abstract

102,150. Powers, J. Nov. 10, 1915, (Convention date]. Statistical machines.-In perforated-recordcard machines of the kind described in Specification 26896/13, a special pin 12, Figs. 3 and 4, is used in conjunction with both a total card and a stop card to actuate respectively the total-taking mechanism and a switch controlling the driving- motor. The pin has portions 13, 14 of different diameters, and is provided with a collar 15 on the part 13 and with a collar 16 on the part 14, a spring 20 being fitted on the part 13. The plates 3, 4 are provided with special perforations 21, 22 for the pin 12, and the total card is provided with a small perforation to allow the pin to rise until the collar 16 meets the surface of the card, as shown in Fig. 3, the stop card being provided with a perforation large enough to permit the passage of the collar 16, as shown in Fig. 4. An extension 24 of a link 25 passes through a slot 23 in the lower end of the pin, and is adapted when a stop card is in position, to engage a collar 32 on a rod 33 connected to the switch box 34, Fig. 1. The link 25 is pivoted to a bellcrank lever 27 having a roller 29, engaging a cam-groove 30. and has a slotted end engaging over an arm 37 of a lever 35. This lever has a part 9 connected bv a link 11 with an arm R, Fig. 1, en the total-taking shaft 7. When ordinary record-cards are being fed through the machine, the pin 12 is prevented from rising, and the slotted end of the link 25 engages the arm 37 above a lug 38 thereon, the extension 24 being depressed out of the path of the collar 32, and the link 25 reciprocating without moving the arm 37. When a total card is fed into the machine, the end of the link 25 engages the lug 38 on the arm 37, as shown in Fig. 3, and thereby rocks the arm 8 on the total-taking shaft 7. In the case of the stop card, the end of the link 25 passes below the lug 38, and the extension 24 is placed in the path of the collar 32, as shown in Fig. 4. The reciprocation of the link 25 then moves the rod 33 without, however, rocking the arm 37.
