TIME-CHECK.

SPECIFICATION forming part of Letters Patent No. 583,169, dated May 25, 1897.

Application filed October 12, 189i. Serial No, 608,586. (No model.)

To all whom, it may concern:

Be it known that LJ OHN LORIMER CORRETI, watchmaker, of (35 Jamaica street, in the city of Glasgow, Scotland, have invented certain new and useful Improvements in Ti me-Ghecking Apparatus, of which the following is a specification.

This invention, which relates to apparatus for checking the time of arrival or departure of workmen, has for its object to adapt ordinary clockwork to operate a chute or del'lec tor which serves to direct the workmens time checks into one or other of the boxes or compartments provided for the reception of early and late checks.

The invention is illustrated by the accompanying drawings, Figure 1 of which is a front elevation, and Fig. 2 a side elevation, of the apparatus.

An ordinary American clock A may be conveniently employed, and with its case B is combined a locked box or case G, containing two, three, or more drawers or compartments D, adapted to receive the workmens checks or tallies, one box being for the reception of the checks of workmen who arrive early or in time, a second for those of workmen who arrive, say, within a quarter of an hour of time, and a third for those of workmen arriving over, say, fifteen minutes late. A slit 0 is provided in the top of the box or case 0, through which the checks or tallies are dropped, and within the check-case O is fitted a chute or deflector E, which is preferably of L or T shape or formed by a flat plate having its upper end bent over at about right angles, as shown at Fig. 1. This deflector E is centered or fitted to swing on a pivot e at or near its mid-length, its movement being governed by the striking part of the clockwork mechanism A, so that in one positionit directs the checks or tallies inserted through the slits 0 into one compartment D, in another position it directs them into another compartment, and in an intermediate position the angled or bent upper end of the deflector closes the slit 0 and intercepts the checks or prevents their insertion, Thus the deflector E when operated by the clockwork A first opens or uncovers the slit 0 to admit the tallies of the early arrivals into the early box, when again operated serves to direct the tallies of the late arrivals in thelate box, and, lastly, prevents the admission of the tallies of workmen arriving later than the hours prescribed, the clock A which operates the checking apparatus at the same time showing each workman the time at which he arrives. The deflector E may obviously be arranged to direct the tallies into any one of a greater nu mber of drawers or compartments when it is desired to check the time at a greater number of short intervals, as, for example, every live minutes.

The swing or like movement of the deflector E is effected from the striking mechanism of the clock A by means of a beam or other lever G, one end of which engages the deflector E or a pin or arm 6 on it, while the other end is slotted to engage a crank H on the arbor of the pin-wheel of the clockwork Athat is, the pin-wheel which in an ordinary clock lifts the striking hammer. The usual lockingwheel and striking-hammer for striking the hours are dispensed with and the lockingwheel is replaced by a similar wheel I, having only four notches 2' when the checking mechanism is to be operated at intervals of a quarter of an hour or such other number of notches as may be required when the intervals of checking are varied. The locking-lever J, which engages the locking-wheel I, is lifted by pins 7.; on the minute-arbor K of the clock, the pins 7; being fitted to act at every quarter of an hour or other interval. A disk L is fitted 011 the hour-socket M of the clock, the said disk being either formed with cam-like projections or, as is preferred, being fitted with adjustable projecting pieces 1. These projections Z are spaced apart and adjustable around the disk L to correspond to the periods of the day at which the checking of the workmens time is to be effectedas, for example, at starting time in the morning and at the usual breakfast and dinner hours. As the disk L rotates with the hour-socket M the projections Z in turn act on and lift a lever N, that normally engages a pin 0 on the fly-pinion arbor O and prevents the action of the striking-train, the train being freed on the raising of the lever N by any one of the projections Z. \Vhen the striking-train is freed,

as at any given hour corresponding to that for which one of the adjustable projections is set, the crank H on the pin-wheel I is set in motion and operates the lever G, which swings the deflector E of the checking device from one position to another and thereby (lirects the Workmens checks or tallies into the early or late compartment, as the case maybe.

Having now described the invention, what I claim, and desire to secure by Letters Patent, is

1. In an apparatus for checking workmens time the combination Wit-l1 a casing having a number of receptacles, and a slot for the insertion of tallies or checks, of a single deflector pivoted beneath the slot and adapted when in one position to close the slot and when in another position to deflect the tallies in one of the receptacles, and, clock mechanism for moving said deflector, substantially as described.

2. In an apparatus for checking workmens time, the combination with the casin g having a slot and receptacles for receiving workmens tallies of a deflector pivoted beneath the slot and having a laterally bent upper end adapted in one position of the lever to close said slot, and clock mechanism for swinging said deflector to open the slot and direct the tallies into one or another of said receptacles according to the time of arrival of the workmen, substantially as described.

In an apparatus for checking workmens time, the combination with the locking-wheel of an ordinary clock, of a casing having a slit therein, a series of compartments within said casing, the deflector pivoted within the casing, and a pivoted lever having a sliding pivotal connection directly with said deflector at one end and a sliding connection with the clock mechanism at the other end, substantially as described.

i. In apparatus for checking workmens time the combination with a striking clock of a rotating disk iitted on the hour-socket of the clock and having cam-like projections thereon a pivoted lever normally engaging the iiy-pinion arbor and adapted to be raised out of engagement therewith by said projections on the rotation of the disk, a locking lever adapted to engage a suitably-notched locking-wheel and to periodically release said wheel, a crank on the wheel spindle or arbor, a pivoted lever operated by said crank and a deflector actuated by said lever and serving to guide the tallies entering a casing within which the deflector is placed substantially as described.

5. In an apparatus for checking workmens time in combination, the casin g, havin a slit therein, a plurality of compartments in said casing and a pivoted plate having alatcrallyextending end with means for operating the same, the said lateral end being adapted to be registered with said slit to close the same, and the main portions thereof being adapted to act as a deflector when said slit is open, substantially as described.

Signed at Glasgow, Scotland, this 24th day of September, 1896.
