Abstract: 14,309. Doremus, W. D. July 6. Date and time printing stamps. - In a workmen's time recorder, a circular card for each workman is stamped with the time, at different distances from the centre corresponding to early or late times, the card being rotated at each printing to position for the next impression. Thecards have holes to fit over pins 9, 12, Fig. 2, the latter carrying a wire loop 13 to spring into the split end of the central pin 9 to secure the card. The cards are carried on a series of radial arms 4 on the main shaft 5 manually set by the disk 15, each card being fixed on a pin 9 carried by a spring-controlled plate 6 pivoted at 7 to the arm 4 so that on alinement of the workman's numbered plunger 17 with the slot 19 in the casing, depression of the plunger operates the bent lever 21 abutting against the projection 23 of the plate 6 so as to carry the plate forwards and insert the card between the time wheels and the platen 38. This platen is carried by the spindle 39 having an arm 41 which is raised by the hook 43 pivoted to the bent lever 21 and is tripped by the nose 49 on the hook engaging the heights or hollows of the broadtoothed disk 50 driven by an escapement lever 111. This lever has a spring-controlled pivoted end piece to engage pins suitably placed on the clock-driven pinion 108 so as to trip the platen correctly for early or late printing. The platen spindle is arrested by an arm 47 thereon engaging a stop just before printing so as to allow the spring arm 37 to give a sharp impression. The pin 12 projects from a ratchet-wheel engaged by the pivoted pawl 31 so as to rotate the card at each impression. Full stroke of the lever 21 is ensured by the spring pawl 27 and recesses 28, 29, and the plunger 17 is withdrawn by the spring 18 and is notched at 24 to engage a lip 25 on the lever 21 to ensure correct return of the parts. The platen spindle 39 has an arm 104 engaging the pivoted plate 96, Fig. 11, which carries the ink-ribbon ratchet-operating pawl 95, working between stops 101 on the pivoted plate 102, which is thrown over, against the action of the spring 100, when either ribbon roller is full so as to engage the other ratchet mechanism. A spring pawl 106 keeps the pawl 95 in either engaging position. The type wheels are loose on the shaft 73, Fig. 9, the lowest 70 for tenths of an hour having attached to it the pinion 74 driven from the clock, and the one-toothed disk 78 to engage the toothed disk 79 fast on the countershaft 75 and drive the hours type wheel 71 through gearing 76, 77. To lock the shaft 75 in the meantime, a toothed disk 82 thereon engages the periphery of the single-notched disk 81 attached to the wheel 70, the notch being positioned opposite to tooth 78 to allow the transfer to take place. The type wheel 72 has type for A.M. and P.M. of each day and is operated by an arm 86 on the shaft 75 and has locking-mechanism similar to the disks 81, 82, The pinion 74 is driven intermittently by the pinion 63 loose on the shaft 60 but connected thereto by the spring 66 which is tensioned by the continuous drive from the clock through the bevelgear 56, 57 until a pin on the disk 67 lifts the spring pawl carried by the pinion 63 from engagement with a ratchet-wheel 62 fast on the shaft, allowing the spring 66 to drive the time wheels.
