DEVICE FOR RECORDING TIME.

SPECIFICATION forming part of Letters Patent No. 297,939, dated April 29, 1884. v

' Application filed January 3, 1884. (No model.)

To all whom it may concern: W

Be it known that we, JOHN KELLER and JOHN F. PERLBAOH, of the city, county, and State of New York, have invented a new and useful Device for Recording Time of Commencing Work in Factories, 850.; and we do hereby declare that the following is a full and correct description of the same.

There'are numerous devices for recording time applicable to and mostly employed'for recording the periodic visits of watchmen -in large establishments; but we are not aware that any device for recording the arrival at work of each individual of a large force of employs has been heretofore used.

Our invention consists, principally, of a suitable box or inclosing-case provided within with a roller or rollers and suitable ratchetand-pawl mechanism, operated by an exterior handle for rotating one of them at will, and a long strip-of paper wound upon one of said rollers, but exposed to sight from without through a narrowaperture. Each person whose arrival is to be recorded is required to write his name upon the strip of paper at the part exposed through the narrow aperture, and then move the paper one stage by means of the mechanism. At the expiration of the hour a proper person will write the time upon the paper and turn it forward, so that all persons writing their names after that moment will stand upon the record late? This constitutes a very effectual and inexpensive method of keeping the beginning time of each employ. In the following particular description reference is had to the accompanying drawings, wherein Figure l is a perspective view of our invention. section of the same. Fig. 3 .is aninner side elevation showing the mechanism. A is the inolosing-case, which may be a simple wooden box with a hinged lid or cover, A, provided with a lock, so that it cannot be opened byanunauthorizedperson. Ataproper point on the cover there are narrow apertures b b, about five-eighths of an inch apart and three inches long, through which a strip or ribbon of paper, M, may pass out of the box and in again, exposing a narrow transverse section. We find it convenient to remove the wood between said slits and substitute aledge, E, which Fig. 2 is a longitudinal vertical is attached to the body of the box, so that the cover may be raised and the strip and mechanism exposed without being disturbed thereby. Within the box there are proper bearings for a roller, D. The long strip of paper M is placed in the bottom of the box, and, if pre- I ferred, wound upon the roller'G, and the outer or free end is passed through the apertures b b and overthe ledge E, and attached to the roller D, so that a narrow section of paper is exposed to sight and accessible over the ledge E; and if the roller D is..rotated the strip of paper will be unwound from the roller 0 and drawn over the ledge E, successively exposing all parts of its surface between the orifices b b.

To effect the desired motion of the roller D, it

the section of paper exposed in the orifices b entirely off the ledge E and within the box, so that anything which has been written upon the paper, the roller D having been moved one stage, will be effectually concealed. Each person whose arrival isto be recorded is required to write his name or number upon the exposed paper, with the hour, and then turn the roller D forward one step. As often as may be desirable, some proper person may write the time upon the paper, and persons tardy will not dare to put down the time falsely, be-' cause it will be impossible to know that the true time has not been inscribed in advance.

The rollers and strip may be easily removed, when desired, for the purpose of entry in the tithe-book or otherwise.

To prevent unauthorized meddling with the apparatus, we think it useful to attach a bell, L, within the box, and arrange its striking device sothat at each movement of the handle J, arm I, and pawl H the bell will be sounded. This also serves to call attention to late arrivals in an unpleasant way.

If desired, an automatic time-recording apat proper intervals beinscribed automatically handle J, whereby the cover maybe raised to upon the strip of paper, and thereby personal attention to that matter may be dispensed with. Having described our invention, we claim- 5 l. The box A, provided with the transverse orifices b b, ribbon M, and the roller D, combined with the ratchet F, pawlsG and H, lever I, and handle J, which, together with said pawl H, are carried by the lever I, substantially as shown, whereby the strip or ribbon, M, of paper may at will be drawn through the orifices-b b, to expose a fresh surface and conceal that already used.

2. The box A, provided with a hinged lid 15 and a wide orifice therein, combined with the ledge E, detached from the movable lid, but located therein, to constitute narrow slits b b. the roller D, provided with the ratchet F, pawls G H, arm I, centered upon the axis of 20 the roller D, curved slot K, and operative expose the internal mechanism without disturbing any of said mechanisms, as set forth. 3. The combination, substantially as shown,

of the box A, provided with a hinged lid having a transverse orifice, and within said orifice, flush with the upper edge of the same, a ledge attached to the box independent of the lid, to produce the two slits or apertures b b, the rollers O D, the ratchet F, pawls G H, and the arm I, on which the pawl H is carried, and the handle J, whereby the paper is exposed on or above the level of the lid, and the .lid may be raised to uncover the mechanism with out disturbing it. 7
