ALFRED GRIFFITHS, OF MANCHESTER, ENGLAND.

WORKMANS TIME-RECORDER.

SPECIFICATION forming part of Letters Patent No. 627,957, dated. June 27, 1899.

Application died March 9, 1899.

To all whom it 71mg concern.-

Be it known that I, ALFRED GRIFFITHS, a subject of the Queen of Great Britain, residing at Longsight, Manchester, in the county of Lancaster, England, have invented new and useful Improvements Relating to VVorkmens Time Checking and Recording Machines, of which the following is a specification thereof.

This invention relates to all classes of time checking and recording machines wherein motion is required to be communicated at definite interrupted periods, and particularly to that class of workmens time checking and recording machines wherein the workman has to sign his name or impress his number on a continuous strip of paper, and in some cases by the additional pulling over of a handle or lever, which causes the exact time or period within which such signature is made or number impressed to be printed close to the said signature or number; and the object of this invention is to construct a mechanical apparatus which shall change or alter the type of such checking and recording 'machine once in any given periodas, for instance, once.

every minutes0 that the machine will always be in a condition to print the exact time or the period within which such signature is made or number impressed.

The manner in which my said invention is to be performed or carried into practical effeet will be readily understood on reference to the sheets of drawings hereunto annexed and the following explanation thereof.

Figure 1 on the drawings is a partial sectional elevation, and Fig. 2 a side view, of the works of an ordinary eight-day clock with my invention shown as applied thereto. Fig. 3 is a'continuation of Fig. 1, and Fig. 4 is a plan of Fig. 3.

Ct is a portion of the frame, and b is the ordinary train of Wheels. I

For the purposes of my invention I provide the clock with a secondary train of Wheels 0. This train of wheels 0 is actuated by a springbarrel d, and it is connected to and regulated by the ordinary train 12 of the clock in the following manner: Upon the arbor e of the center wheel of the clock, which carries the hands, (see Fig. 1,) I mounta ratchet-wheel f, having, say, sixty teeth, in gear with which Serial No. 708,394. (No model.)

is a short ratchet or lever g, to which is attached a long levenh, curved into a hook at the end, which alternately holds and releases an arm 7 fixed on the spindle k, which carries the flyl as the levers g and h are caused to rise and fall by the action of the teeth of the ratchet-wheel f. The holding position of the lever h is shown by the full lines at Fig. 1 and the releasing position in dotted lines. Whenever the fall of the lever h releases the fiy the train of wheels 0 is put inaction by the spring cl. On the arbor of the wheel c of this train is fixed a wheel or disk on, having, say, four teeth, above which hangs a catch 91, which is held up or allowed to fall onto the notched disk m by a lever o, a pin at the end of which rests on the lever h, so that they rise and fall together, the effect of which is that when the fly is released the wheel 0 can only make, say, one-fourth of a revolution-that is to say, the length of one toothon the disk m, which the catch then holds fast until again released.

The disk on may have anysuitable number of notches and is fixed on the arbor of the wheel o which drives the fly, so that every lift of the lever it allows this wheel to turn the flyZ the required number of times. On the arbor of the wheel which drives the wheel e is fixed a pin-wheel 19, having any desired number of teethas,forinstance, fifty-tWo-which gives motion to alever g on a shaft q a lever r on the end of which is connected by a rod T to the type-printing apparatus of the checkingmachine and by its motion gives the necessary pull or lift to change the type from time to time--as, for instance, minute by min uteas may be desired, in the manner shown in Fig. 3 (a side elevation in continuation downward of Fig. 1) and which shows the lower end of the rod r 'provided with a weight 3 and connected to the horizontal arm of abellcrank lever t, the upper end of the vertical arm thereof being provided with a pawl or catch-link a, which actuates the ratchet-wheel 'u, fixed on the arbor of the type-changing apparatus 10, which is of the ordinary known construction and a plan view of which is shown at Fig. 4.

I claim as my invention-- v 1. Mechanism for controlling a workmans time checking and recording machine having time, and to afterward release the fly and allow the catch tocheck the notched disk, substantially as described.

2. Mechanism for controlling a Workinans time checking and recording machine, consisting of a clockwork, a ratchet-wheel oper- I ated by the clockwork, a catch and lever opi erated by the ratchet-Wheel, an additional train of Wheels havinga fly, a notched disk and a catch, a pin -Wheel, a rod operated thereby, said lever adapted to act upon and check the fly and release the catch when in one position and to check the catch and release the fly when in another position, whereby the notched disk is permitted to revolve a predetermined distance and revolve the train of Wheels thereby advancingthe pin- Wheel, substantially as described.

In testimony whereof I have signed my name to this specification in the presence of two subscribing Witnesses.
