Abstract: 483,236. Statistical machines. HOLDEN, N. G. Oct. 10, 1936, No. 27576. [Class 106 (i)] A grouped card - controlled machine in which the designation is printed only off the first card of a group and at total-taking, comprises swinging or reciprocating actuators which coact with type carriers and accumulator wheels, means for locking the designation printing actuators at normal and for unlocking them only at totalprinting and during the succeeding first-card cycle. The invention is described in a record card controlled machine in which the nought stops 1 are normally held up by springs to arrest the swing- ing sectors 18. If, in a column, an ordinary stop 11 is raised by the card reading, a pin 13 on it cams a slide 14, 15 to the right to rock a bell-crank 17, 6, 4 anticlockwise about its pivot 5 so that the arm 4, through pin-and-slot 3, 2, pulls down the nought stop of the column ; whereby the sector 18 is freed to move across to the raised stop 11. In order to print the group designation number only from the first card of a group and when the total for that group is printed, the following means are used. The nought stop 1 for each column in which a group designation number may be punched, has a lug 19 co-operable with the end 20a of a corresponding slide 20. These slides are pulled to the left by springs 24 so that their pins 28 rest against a comb bail 27. If a slide is permitted to move to the left fully its end 20a locks . the nought stop against downward movement 1 and prevents designation-printing in that column. Any slide 20 may be made inoperative by pulling it to the right so that its notch 25 is engaged by the lower edge of the guiding slot in plate 21. Fig. 2 shows the position of the parts immediately after a totaltaking operation. Secured to the shaft 26 carrying the bail 27 is an actuating plate 29 with a pin 30 overlying a resetting lever 31 on the back total shaft 8, which is rocked when a total cycle occurs. Shaft 8 is rocked by a cam on the total shaft 96 (not shown) described in Specification 483,234. Part 29a of plate 29 coacts with shoulders 34a, 34b and steps 36, 36a on a latch 34 pivoted on shaft 35. With part 29a on step 36a as shown, the slides 20 are held half-way to the left. Pivoted on shaft 35 is an arm 38 to which is pivoted at 40 a pawl 39 coacting with teeth 48, 48a on the latch 34. Pivoted at 41 to arm 38 is a link 42 on the sector restoring shaft 45 (not shown) described in Specification 483,234. During the early part of the next revolution of the main shaft, the first card of the next group is sensed and during this time the pawl 39 remains as shown. After the stops have been set, arm 38 is moved counterclockwise by link 42 so that pawl 39 causes part 29a to drop off step 36a and pin 30 falls on lever 31. Part 29a also holds the shoulder 34b. This movement of plate 29 allows bail 27 to move to the left so that slides 20 lock the nought stop lugs 19, thereby preventing designation-printing from the succeeding cards of the group. As each card passes through the machine, pawl 39 rocks idly. When the card group changes, card feeding is stopped and the back total shaft 8 rocks, lifting pin 30 through the resetting lever 31, and causing bail 27 to restore all slides 20 to the right. At the same time plate 29 is lifted so that its end 29a is level with shoulder 34a and pin 53 on lever 31 lifts a lug 52 on a lever 50 so that the latter rises on its slot 51 about shaft 35 so that a curved portion 54a meets a pin 55 on pawl 39 and removes the pawl from teeth 48, 48a. Plate 34 is then moved clockwise by its spring 49 until shoulder 34a meets part 29a. Thus when the total is printed, the nought stops 1 are free and the designation number is printed, this number having been entered into counter wheels from the first card of the group. A pin 56 on link 42 then rocks the lever 50 clockwise to remove its lug 52 from pin 53 so that spring 50a returns the lever 50 downwards on its slot 51. This allows pawl 39 to engage the first tooth 48a. When the first card of the new group enters the machine, the sector-restoring shaft 45 (not shown) causes pawl 39 to step the latch plate 34 one tooth so that plate 29 falls on to the step 36a and the slides 20 move to the half-way position shown with the nought stops 1 still free. On the next movement of shaft 45 (not shown), the pawl 39 steps the latch 34 one more tooth and the slides 20 lock the nought stops 1 till the next total-taking cycle.
