Abstract: 37. Roberts, T. H. Jan. 1. Time-checking apparatus for workmen. Improvements on the inventions described in Specifications No. 1614, A.D. 1888, No. 14,075, A.D. 1894, and No. 23,454, A.D. 1898, provide means for (1) locking the minute and hour wheels at the precise moment of printing; (2) rendering the printing-mechanism inoperative during certain hours; (3) grouping and dividing the time or record sheet according to departments or classes of workmen ; (4) die-stamping the typeband and mounting it in correct alignment for printing. At the precise moment of printing, both the minute and the hour wheels are locked. The minute-wheel is rendered inoperative by the engagement with a serrated ring 39, attached to the minute hand 20, of the end of a small rock-lever 44, which is connected by a spring 43 with the ribbon-actuating. rod 42. On the depression by the operator of the handle 1, motion is communicated to the rod 42 by the rods 2, 3, the spring-pressed sliding sleeve 5, and the pivoted levers 9, 40. Except when the hour wheel is required to move at the expiration of each complete hour, the hour wheel is locked by the minute wheel. The spindle of the minute hand 20 frictionally carries a locking-wheel 21 and an adjustable lever 23, so that all these parts rotate together. The hour-printing wheel 32 is adjustably mounted in a slide 27, which is frictionally held in the forked end of the frame 18<1>. A stud 36 on a spring-pressed lever 35 pivoted on the slide 27 locks a dividing-wheel 33, mounted on the spindle of the hour-printing wheel 32, except when, at the expiration of each hour, the recess of the locking-wheel 21 comes opposite the stud 38 on the lever 35. The lever 23 then engages the dividing-wheel 33, and rotates it by one tooth. The printing- mechanism is rendered inoperative, except during such hours as may be required, by turning the spindle 13 of the indicating-disc 14 one half a revolution by means of a key. The disc 14 is connected by a link to a second disc 11, to which is pivoted one end of a connecting-rod 12, which, when the disc 14 is turned, forces up the sliding lid 8 of the actuating-lever 9 of the printing-mechanism out of the path of the sleeve 5, so that any depression of the handle 1 will be ineffectual. The rotation of the disc 14 may be electromagnetically controlled from a contact band driven by the clock mechanism 10, which is elastically connected to the printing-mechanism. The durability of the type-bands, Fig. 6, is increased by making them of brass or other material capable of being hardened by being pressed in a die, Fig. 5, in which the numbers are cut in intaglio and which has gauge marks 45 to indicate where the band is to be cut so that it will exactly encircle the printing- wheel. The peripheries of the printing-wheels and the inner faces of the bands are then coned as shown at 47, 46, Fig. 4, and the bands are heated and shrunk on to the wheels, thereby ensuring correct alignment in printing. The recording by the workmen is facilitated by adjustably attaching to the numeral dial 48, in the manner shown in Fig. 12, several indices 49, one for each department or class of workers. As the projecting arm 54 blocks the entrance to one numeral hole, a blank space line is left on the record sheet between any two sections.
