Abstract: 9114. Foley, J. S., and Looker, A. E. April 18. [Cognate Application, 21,703/13.]. Factory and like timerecorders, detached-key; inking-arrangements. - The workman inserts his key in one of a number of apertures 22 in a slidable plate 21 and thus marks a number or sign on a record disk 15 rotated once in 12 hours. The slidable plate is shifted radially by the clock-work at the end of this period so that the marks are made in different circles on the disk during the second rotation of the disk. The disk is secured to the hour spindle of the clock-work 11 by means of arms 19 fixed on the spindle and having projections 20 adapted to enter holes in the disk. The various projections and holes may be differentiated to ensure that the disks are correctly placed relatively to the clock hands. The disk is divided by radial lines 25 into hours and five-minutes and by concentric lines to form marking spaces corresponding with the number of keyholes in the plate 21. Each of these marking - spaces is further divided, for instance by a red line 26, Fig. 8, and the arrangement is such that, during the first twelve - hour period, the employee's marks appear on one side of these dividing lines and then, the plate 21 being moved, the subsequent marks are made in the spaces on the other side of these lines. The plate 21 is mounted on the hinged cover 13 of the instrument, and when the cover is closed, the plate is connected by a pin with a frame 32 slidably arranged below the record disk and attached to a link 41, Figs. 10 and 11. A pinion 33 on the hour spindle turns a wheel 34 and gradually winds-up a spring in a drum 39, bnt at the end of the 12 hours, an eccentric on the wheel 34 has swung over a lever 45 so that one of two projections 48, 49 on it releases a pin 50 on the drum. Under the action of the spring, this drum then suddenly rotates through 180 degrees until the pin 50 meets the other projection 48, 49. This rapid half-rotation of the drum effects, through an eccentric 39<x> thereon and a strap 40, the necessary movement of the frame 32 and plate 21, and these thereupon become locked until the next 12 hours have elapsed. The keyhole plate 21 has a depending web 29, Fig. 17, grooved to guide the key-stems and a pivoted flap 64 co-operating with this web is moved whenever a key is inserted and actuates the hammer of a bell. The keys move the record disk against an ink-ribbon carried by a cylinder 51 intermittently rotated by a ratchet feeddevice 61 whenever the cover is shut. In a modification, instead of the cylinder, an annular sheet of carbon paper is rotatably mounted above the record disk, so that this is marked on its upper surface. According to the first Provisional Specification, the keyhole plate is moved gradually by a spiral cam rotated by the clock so that the records may be impressed on either side of spiral lines dividing the recording-spaces according to whether the record is made during the first or the second rotation of the disk. Moreover, two keyhole plates arranged diametrically opposite each other may be employed and records may be made on both surfaces of the disk.
