Title: A punched card reproducer
Inventor: VODEHNAL JIRI
Filed: 1957-09-04
Abstract: 841,076. Selective punching machines. ARITMA, NARODNI PODNIK. Sept. 4, 1957, No. 27932/57. Class 31 (2). In a punched card reproducer comprising a vertically displaceable unit 10 having needles 23 for reading out data from basic cards and an interchangeable transfer device 11 having wires 41 for introducing the read-out data into a punching mechanism, a pin box 54 for permitting correction of the read-out data in individual columns is arranged between the transfer device and the adjustment box 55 of the punching mechanism, and links 57, 58, operable by slide keys are movable between the individual columns of pins 56 of the pin box, slides 59, 60 associated with the links having ramps movable over pivotally-mounted spring-influenced pawls 61, 62 which are operatively connected to cancelling levers 67, 68 so that when a link 57, or 58, is pulled to the left, the read-out data for the corresponding column is cancelled and correctly coded data is punched in a column or columns of the card according to the position of the link. Upon movement of a cam-operated axle 71, Fig. 1, to the right, the cancelling levers 67, 68 displace corresponding slides 76 of the adjustment box 55 to the right so as to release pins 77 which have been depressed during the reading-out operation. After the punching stroke, a cam-operated axle 79 is moved upwardly to shift all the levers 67, 68 against protrusions on the slides 76. The punching mechanism comprises a spring-influenced box 83 which lifts the pins 77 and 56 to their original positions during the cancelling operation. The card to be punched is fed over a matrix 85 which is raised together with the card against punches 84. The punching operation is carried out only by those punches which are supported by pins 88 and secured by pins 77. If it is desired only to cancel the read-out data in a certain column, the corresponding slide key is moved to the position M, Fig. 2. The invention is especially applicable to the correction of faulty cards. These are taken from a checking station, inserted successively in the feed hopper 1, read-out by the unit 10 and stored in an illuminated hopper 19. The operator then pulls to the left the respective slide 59 or 60, corresponding to the faulty column of a card, to indicate the correct value. A new card is then punched according to the original card but with the correction. The machine permits the reading-out of damaged cards. In a modification, Figs. 4 and 5 (not shown), the transfer device is modified to permit the transfer by means of Bowden cables from one point of the read-out card to another point of the card to be punched.

Title: Devices for squaring flat collapsed tubular folding box blanks
IPC: B65B43/30
Filed: 1963-07-19
Abstract: 973,992. Erecting cartons. ATLAS GENERAL INDUSTRIES Inc. July 19, 1963 [July 26, 1962], No. 28582/63. Heading B8C. In a device for erecting collapsed tubular box blanks, the blanks are removed singly from a magazine by suction cups which move along a curved path past a blank engaging and blank opening obstacle to a delivery point at which the plane of the suction cups makes an angle with the plane of the blanks in the magazine, the obstacle being closer to the apex of this angle than the suction cups in any position along their curved path. The blanks are retained in a magazine 11 by an upper plate 18 and a lower plate 20. The suction cups 23 are mounted tiltably on an arm 25 by a carrier 24, the tilt being controlled by an arm 27 rigid with a sliding bearing 28 engaging a fixed stud 29. The suction cups attach themselves to the blank and move along a curved path withdrawing it past the plates 18, 19 and depositing it (Fig. 3) on a conveyer 33, 34. Guides 38, 39 steady the blank during transit. During the movement the blank slides over a shelf 21 causing folding about the line 41. The dimensions and position of the shelf 21 are arranged so that side panel 43 is caused to fold to an acute angle with top panel 44, thus reducing the tendency of the blank to recollapse. The blank is dropped into a compartment of a conveyer moving in the reverse direction to that of the blank removal formed by leading and trailing lugs 35, 36 on the conveyer 33, 34, the trailing lugs moving faster than the leading lugs and thus decreasing the length of the compartment, thereby squaring the blank, guide rails 45 being provided to prevent the blank from jumping out of the compartment. Ramp structures 49 may be provided to raise the leading edge 47 so as to engage the lug 35 at a point high enough to provide clearance for the leading box panel which moves into an upright position without undue sliding. The suction cups are mounted on bellows 23<SP>1</SP> causing cups to be slightly retracted on contact with the blank, ensuring that the front of the blank is moved away from the back before encountering the obstacle. The control mechanism for the suction cups may be modified by linking the arm 27 to the stud 30 by a drag link to allow the blank to be released from the lip 18 without tilting. The blank is prevented from tilting forward by studs 40 or by fitting a U- shaped plate to the carrier 24.
