TIME-RECORDER.

SPECIFICATION forming part of Letters Patent No. 748,800, dated January 5, 1904.

Application filed March 24, 1908. Serial No. 149,374. (No model.)

To all whom it may concern:

Be it known that we, HENRY F. SHILLING and JOHN C. DIETER, citizens of the United States, residing at Troy, in the county of Miami and State of Ohio, have invented certain new and useful Improvements in Time-Recorders; and we do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

Our invention relates to improvements in time-recorders adapted for use by policemen, watchmen, and others when they make their rounds to indicate that they have performed their duty at the prescribed time; and it consists in the peculiar construction and combination of devices hereinafter described and claimed.

In the accompanying drawings, Figure 1 is a sectional view of a time-recorder embodying our improvements. Fig. 2 is a detail front elevation of the time-recording mechanism, showing the time-dial. Fig. 3 is a similar view with the time-dial removed and disclosing the subjacent operating mechanism for moving the time-dial and synchronously moving the recording-stylus.

In the embodiment of our invention we employ a suitable time mechanism or clockwork which is preferably the time mechanism of an eight-day clock. The same is indicated at A, and on the arbor 1 for the hourhand is mounted a ratchet-wheel 2 and a gear-wheel 3, the same being secured together and adapted to rotate simultaneously. A spring-keeper 4 is employed to bear on the outer side of the ratchet-Wheel and keep the same in position on the arbor. The gear 3 is provided with a central opening, the diameter of which exceeds that of the arbor or sleeve 1 and is adapted to receive a sleeve 4, which latter sleeve is adapted to be fitted frictionally on the hour arbor or sleeve 1 and to be rotated thereby. The said sleeve 4: has a flange 5 and its outer portion is exteriorly screw-threaded. A gear-wheel 6 is mounted on a suitable stub-arbor which projects from the front side of the frame 8 of the clockwork, and said gear 6 engages the pinion B with which the hour sleeve or arbor 1 is, as

is usual, provided. The relative sizes of said pinion and gear are such that the latter is caused to make half a revolution while the pinion is making one complete revolution during the period of twelve hours. At diametrically opposite points the gear 6 is provided with outwardly-projecting tappets 9, of which there are two, adapted to engage successively with the ratchet-wheel 2, and hence partially revolve the latter to a slight extent and also revolve the gear 3 a corresponding extent at each semirevolution of the gear 6 and complete revolution of the hour arbor or sleeve and the pinion B carried thereby.

A stylus 10 is here shown as a spring-arm having a point 11 at its outer end and extending inwardly therefrom. This stylus is secured to a sleeve 12, which is revolubly mounted on a stub-shaft 13, that projects from the front side of the frame 8 and carries an arm 14, which has at its outer end a segmentrack 15, engaged by the gear 3. Hence it follows that at each partial rotation of the gear 3, as hereinbefore described, the stylus is moved to a slight extent.

We also'provide a time-recording dial 1 6, which in practice is preferably made of paper or cardboard and is of suitable size. The same is inscribed on-its face with a series of concentrically-disposed circles 17 18, which indicate the hours of the day and night, and the number of these circles will be varied according to the time during which the time mechanism will operate at one winding. Thus if the time mechanism be that of an eight-day clock there will be sixteen of the said circles l7 18 on the time-recording dial 8 of each. The hours of the day are also inscribed on the face of the time-recording dial, as shown, and the same is further provided with volute lines 19, which run from near the center to the circumference of thetimerecording dial and which indicate the divisions of time, as hours, half-hours, quarterhours, or the like. The clock-casing has its outer side 0 provided with a curved slot 21, which registers with the point of the stylus, and is also provided with a guide 22, the same being here shown as a spring-arm.

The time-recording dial 16 is secured 011 the flange 5 of the sleeve, which is carried by the hour arbor or sleeve of the time mechanism, a screw-cap 23 being here shown, which is adapted to be screwed on the said sleeve 4 and to clamp the time-recording dial between it and the flange 5, so that the time-recording dial will be revolved by the hour arbor or sleeve 1 of the time mechanism and will make one complete revolution during any predetermined period of time, (in the present instance twelve hours,) corresponding to the numbers indicating the hours on the said dial.

It will be understood from the foregoing description that the stylus will be set so that the same will have its point in register with one of the night-circles 17 during the twelve hours of the night and so that the same will be moved by the mechanism hereinbefore described automatically into register with the next day-circuit in sequence at the expiration of the said period of twelve hours, and so on from day to day during the entire number of days in which the time mechanism is constructed to operate at one winding. It will be understood that the time-recording dial will be appropriately adjusted with reference to the stylus, so that the point of the latter in connection with the stylus, which revolves under it, will indicate the time, and that if the stylus be depressed so as to cause its point to puncture or mark the timc-dial16 the latter will correctly record the fact, and hence will serve to indicate the time whether during the day or during the night that the stylus is so operated.

Within the scope of our invention any suitable means may be employed for operating the stylus to cause the same to make its recording-mark on the dial. We here show a push-button 24 in the door 25, that forms one side of the outer casing 26, which push-button is normally moved outwardly by a spring 27 and carries at its inner end a disk 28 of sufficient size to cover the movable end of the stylus under all conditions, so that when the push-button is pressed by the watchman or policeman on his round the stylus will be caused to puncture or mark the dial, and

hence record the time at which the stylus was so operated.

The time-recording dial may be readily removed at any time and maybe dated and preserved indefinitely to serve as a record. In practice a fresh time-recording dial will be attached at any desired given period of time once every eight days if an eight-day time mechanism is used, &c. It will be understood from the foregoing that our improved time-recorder requires very little attention to keep it in operation.

From the foregoing description, taken in connection with the accompanying drawings, the construction and operation of the invention will be readily understood without requiring a more extended explanation.

Various changes in the form, proportion, and the minor details of construction may be resorted to without departing from the principle or sacrificing any of the advantages of this invention.

Having thus fully described our invention, what we claim as new, and desire to secure by Letters Patent, is-

In combination with a time mechanism having an arbor, a pinion on the latter rcvoluble therewith, a gear 3 and ratchet-wheel 2 connected together for rotation and revolubly mounted on the arbor independently thereof, a gear 6 engaged by the pinion and having tappets 9, the latter coacting with the ratchetwheel to revolve the gear 3 by a stepby-step movement, a time-dial revolved by the arbor, and a pivoted marking element adapted to swing radially with respect to the time-dial and having an operating-gear engaging the gear 3, substantially as described.

In testimony whereof we have hereunto set our hands in presence of two subscribing witnesses.
