Abstract: 27,141. Fairweather, W., [Lathrop, F. B.]. Dec. 29. Time - checking apparatus for workmen. The apparatus is designed to make a permanent record of the time when each employee enters or leaves a place of business, and comprises a record-sheet bolder and clock mechanism for moving it gradually and a marking - device movable across the record sheet and adapted to imprint one or more characters at selected points. The record sheet 19, Fig. 2, provided with vertical rulings numbered to provide separate columns for the individual workmen and horizontal rulings to indicate time, is mounted on a guided bar 10 connected by a chain 15 to a pinion 33 driven by clock-work mounted in the case 2. The clock-work raises the record sheet for twelve hours, when it is put out of action by a tripping-lever 37, leaving the record sheet free to descend under the control of a fly-wheel 41 which automatically comes into gear. The door of the casing enclosing the mechanism is provided with a flanged ring in which are cut numbered notches, and pivoted to the centre is a pointer 54, Fig. 3, adapted to be swung round to register with any selected number. The movement of the pointer rotates a pulley, Fig. 7, and through a chain 67 moves the marking- device 70, feathered on a transverse bar 60, into registry with the column on the record sheet corresponding to the selected number on the dial. On depression of the lever 54, a pin 52 moves a crank 62 on a shaft 59, -which through lever mechanism rocks the shaft 60 and brings the printing-device against the record sheet to impress the hour and minute. The printing - apparatus indicates by marks of different appearance whether the time recorded is that of arrival or departure. For this purpose, a plate 70 keyed to the feathered sleeve 60<1>, Fig. 4, is formed with a printing-surface 71 and provided with a pivoted piece 73 having a printing-surface 72. A flattened shaft 61 is connected by a link 79 with a spring-controlled crank 80 on a shaft 81 which is provided with an exterior handle movable to an 'in' or ' out' position. When an employee enters, he moves the handle to the " in " position, and both printing-surfaces are moved forwards ; when he is leaving, the handle is turned to the out' position and the lever 73 is held back by the shaft 61. The handle must be turned to the 'in' or 'out' position before a record can be made, as a crank 63 on the shaft 59 is held by an extension of the crank 80. The turned-up end of a lever 85 holds the handle in either position by engaging with notches in a disk 83 until released by the forward movement of the crank 63. In a modification of the 'in' and ' out' mechanism, a piece 100, Fig. 17, with studs 103 and a rounded boss 105, replaces the disk and crank. A lip 110 on a spring-controlled lever 109 bears against the crank and locks the recording- mechanism until turned aside by the handle rotating the piece 100. The piece is returned to its original position by the crank 63 pushing aside the rounded head of the boss 103. To give the printing-device a quick rocking movement to ensure a clear impression, the shaft 59 is provided with a crank 64, Fig. 8, connected to a disk 68 on the shaft 60 by a link 90 having an inclined slot 92 and also by a spring 89. The rocking of the shaft 59 moves the link to abut against a lug 91 arranged below until the pin on the crank 64 engaging with the inclined wall of the slot 92 movesthe link 90 outwardly until clear of the lug 91, upon which the spring 89 being in some tension rocks smartly the shaft 60.
