Abstract: 4668. Wood, W. A. Feb. 26. Time - checking apparatus for workmen. The carriage 16, Fig. 1, with type -wheels is supported by a sleeve on a shaft 18 and guided by a bracket 20 sliding on a shaft 19, motion being communicated from the minute spindle of the clock by sprocket gearing to a telescopic shaft connected by a collar 35<a> to the arbor 44 of the minute type - wheel This also carries a onetoothed cam 80, Fig. 6, engaging the finger 86 of the lever 81, Fig. 10, which in its descent drives the hour-wheel round by means of the pawl 87, a pawl 94 being provided to remove the hour justifying-lever 91, by engaging the pin 97 thereon, just before the action of the pawl 87. The minute justifying-wheel 202 is engaged by a curved finger 201 on a shaft 203, rocked by an arm 204, Fig. 7, and link 206 from the lever 207, which is struck by a bar 435, Fig. 4, attached to the platencarrying arms 431, play being allowed between the link 206 and the lever 207 by a spring as shown. The rocking shaft 203 also actuates by means of the arm 230, link 232, and lever 233 with spring pawl 234 the ratchet-wheel 235 on the shaft 237 carried by bearings 238 in a plate 239, which is fitted with blocks to slide in the frame of the carriage, and thus bring into gear with either of the ink-ribbon bobbin pinions 247, 248 the corresponding pinion 245, each of which has a bevel pinion always in gear with the shaft 237, thus enabling the ribbon to be fed forward at each stroke of the platen. The plate 239 is shifted so as to reverse the ribbon feed by the usual rocker 300 throwing over the slotted lever 325 and with it the lever 329 on the fixed pivot 829, which lever is attached to the slotted lever by a spring 628, and this after passing the dead point throws forward the end 327 of the lever 325 and with it the bar 351 attached to the sliding plate 239. A slight play is allowed by screw-aridslot attachment between the bar 351 and the plate 239 to allow the former to lift one or other of the spring arms 360, which engage shoulders on the plate 239 so as to hold the pinions 245 in gear with the ribbon-dram pinion. A two-colour ribbon is employed, the ribbon spools being located between a pair of wings 400, Fig. 9, connected to a rack 402 so as to be shifted on the stroke of the lever 207 by means of the linkage 405, 406, 407. The colour is selected by a cam 420, Fig. 4, which allows the link 410 to engage the lever 207 and actuate the linkage, a pivoted piece 425 being interposed between the link 410 and the cam to allow sliding. The carriage is traversed along the shaft 18 by the cord 22 from the spring drum 21, and has a detent pawl 25 bearing in turn on a series of bevelled disks 24 on a clock-driven shaft 27, recesses in the disks being arranged to allow the carriage to move forward. The platen 430 is carried by lever arms 431 and actuated by the bent lever 451 from the push-pin 6 of the workman's lever which is fitted with a revoluble cylindrical block 7 having pins 4, 10 at its opposite ends, this arrangement allowing a workman to print the time in the 'in' or 'out' column. A spindle 32<a> bearing against the disk shaft 27 allows the latter to be moved when the type-wheels are shifted to print in the previous column. At each registration, the platen actuates a gong hammer 530 and the pawl 555 of a counting-device 550. An auxiliary card printing-device for piece-work registration is fitted as shown at Fig. 4, the timewheels, which may carry distinguishing-type, being driven from the main clock-work mechanism by suitable gear. The platen 610 is carried by forked arms 611 on the bent actuating-lever 612, which also carries guides 614 for the card. A stop 663 for the card is carried by a rack 660 and adjusted by bevel-gear from a handle 668.
