Abstract: 15,592. Boult, A. J., [Jaynes, A. L., and Johnson, A. S.]. July 22. Time-checking apparatus for workmen &c. Relates to card machines and consists in improvements for automatically effecting a lateral movement of the card-holder, for locking the holder in certain positions, for ensuring that the time shall be printed only in the proper space on the card, for manually shifting the multi-colour printing-ribbon, for indicating the nature of the record, and for effecting a vertical movement of the card stop. The card-holder is moved transversely in front of the time - printing mechanism by mechanism operated by the clock. The holder 9 is connected by a pin-and-slot connexion 12 to an arm 11, which has a projection 17 engaging a snail 16 on a shaft 15 so that, as the shaft 15 rotates, the holder is moved forwards. A ratchet-wheel 18 on the shaft 15 engages a ratchet-shaped piece 19, which is pivoted at one end to the arm 11 and connected by a pin and slot at the other end to the arm. The card-holder is thus prevented from moving forwards except when moved by the snail 16, while the pin- and-slot connexion 12 permits the holder to be moved back if it has moved too far for a particular entry. The mechanism for operating the shaft 15 consists of a snail 27, Fig. 3, on a shaft driven through gearing by the clock, whereby a connecting-rod 28 attached to a pivoted weighted lever 29 is alternately raised and allowed to fall. Mounted on the lever 29 is a spring-actuated dog 32, which engages a square ratchet-wheel 33 fast on the shaft 15. The shaft 15 is also provided with a notched wheel 35, which is held by a spring detent 36. The detent is released by a projection on the dog 32 when the shaft is rotated. A projection 108 on the lever 29 enters one of the notches on the wheel 35 when the lever drops, ensuring that the wheel is in position for engagement by the detent. To indicate the position of the card-holder when different exit and entrances are to be recorded, the holder is connected to an indicator consisting of a plate 39, Fig. 1, which carries an inscription and moves behind an opening in a face-plate 40. The printing-hammer 7, which is arranged to be drawn forwards by a spring, is retracted and subsequently disengaged by a dog 46, Fig. 2, pivoted on the main operating-lever 47. The colour ribbon is caused to move backwards and forwards by means of studs 63 on the ribbon, which engage levers 61 so as to rock them. The levers 61 put a shaft 58, rotated by the operating-lever 47, into gear with one of the wheels 56 mounted on the lower ends of the shafts carrying the ribbon spools. The spools are mounted in manually-operated U-shaped frames 71 so that the ribbon may be depressed vertically to bring either part of the ribbon in front of the hammer. Each frame 71 is pivoted to arms 72, Fig. 5, secured on a spindle 74. The arm 72 is raised or lowered by a lever 73, a pin on which engages an inclined portion of the lever 72. The ribbon in use is shown by the indicator 101. This consists of a fan-plate with colour spots, which moves behind an opening in a face-plate and is connected to one of the arms 72. The abutment 79, Figs. 2 and 3, upon which the card rests is moved vertically by a snail 80 mounted on the same shaft as a ratchet-wheel 82. This wheel is moved by a gravity dog mounted on a bent lever 83 on the shaft of the snail 79. The lever 83 is periodically rocked through a rod connected to the clock mechanism. To prevent printing before the card is inserted fully, the lever 47 is held by a detent 90, Fig. 2, which is released when the card is pushed fully home. The detent is also provided with one or more pins 97 which prevent the operating-lever from being slightly depressed and the card from being partly withdrawn before printing. The card is also held by a gripping- device, Fig. 6, consisting of a lever 98 carrying a pin 99, which is pressed towards the card by a spring when the hammer is retracted. When the hammer is in its normal position, an arm 100 on the hammer shaft bears against one end of the lever and withdraws the pin from the path of the card.
