Abstract: 2617. Larrabee, C. E. Feb. 3. I'actory &c. time-recorders, card type. - The card-carrying device is moved into the printing-position by a locating-bar which is normally disconnected from the time - carrying device, and is adjusted by time - controlled mechanism. Where the position of the sheet &c. is normally determined by a clock-controlled member, this member may be adjusted independently of the time - controlled mechanism to permit of the movement of the card - carrying device to abnormal positions. The card-receiver is connected by a link 16 to an arm 17, which is pivoted to a fixed plate 18 and carries a stud 19. A lever 21, pivoted to an arm on a shaft 26, has a V-shaped notch at one end. When the notched end of the arm 21 is depressed, it moves the arm 17 and receiver until the stud 19 enters the recess 24 in the notch, thus forcing the receiver into the printing - position. The locating-bar 21 is depressed to engage the stud 19 by means of a pivoted plate 55, Fig. 3, which is operated from the main operating-lever 10. When the lever 10 is depressed, a projection 56 on the plate 55 'engages the bar 21 and forces it downwards. At the same time another extension 58 of the plate 55 enters one of the flared notches 61 in a plate attached to the receiver, so as to force the receiver into the exact position required. The shaft 26 is operated either by the clock or manually. The clock drive is obtained through a time-setting wheel 41, Fig. 1, provided with lifters 44 which engage a projection on the lever 40. The lever 40 is connected by a link to a pawl-carrier 37, Fig. 7, the pawl 38 of which operates a ratchet-wheel 36 rigidly connected to a cam 31. The cam 31 operates a lever 30, which actuates the shaft 26, thus determining the position of the arm 21. To enable the shaft 26 to be rocked in either direction independently of the clock, the lever 30 is loose on a sleeve 27, Fig. 6, to which another lever 28 is fast. The lever 28 is connected to one end of the lever 30 by a spring which tends to keep the lever 30 in engagement with the cam 31 and with a projection 33 resting on the stop end 29 of the lever 28. The shaft 26 may be manually operated by means of a shaft 72 carrying a pin 74, which extends between the forks of a plate 75 fixed on one end of the shaft 26. The shaft 72 is normally kept out of action by a spring-pressed bar 77, which engages lateral pins 76 on the shaft. An index 67, to show the position of the receiver, is mounted on a sliding carriage and is operated through links 71, 69 from the arm 25. In another arrangement, Fig. 16, the manually - operated shaft 72<a> has a flat stud, which engages the end of the shaft 26<a> when the shaft 72<a> is pushed inwards. The shaft 72<a> is normally kept out of action by a spring 80. Fig. 17 shows another form of indicator in which a pivoted arc-shaped member 85 carrying the indications is operated from the arm 21 through a link 69<a>. Impression mechanism.-The printing-hammer 2 is mounted on a shaft 8 upon which the main operating-lever 10 is also loosely mounted. When the lever 10 is depressed, a pawl 11 thereon engages a finger 12 on the shaft 8 so as to retract the hammer. Ultimately, one end of the pawl 11 engages a cam-stop 15, thus causing the pawl 11 to release the finger 12. The hammer is then thrown against the printing- devices by a spring 14. Inking-arrangements. - A two-colour ribbon 102 may be adjusted vertically by lifters 103 on a wheel 47, which is similar to the wheel 41.
