IMPROVEMENT lN WATCHMENS TIME-DETECTERS.

Specification forming part of Letters Patent No. 156,098, dated October 20, 1874; application filed September 19, 1874.

To all whom it may concern:

Be it known that I, ANTON MEYER, of Stuttgart, Wurtemberg, Germany, have invented a new and Improved Watch m ans Time- Detecter, of which the fhllowing is a specification:

In the accompanying drawing, Figure 1 represents a top view of my improved watchmans time-detecter, with lid thrown open to show interior construction; and Fig. 2 is a partial vertical transverse section of the same on the line 0 c, Fig. 1, showing arrangement of the marking devices.

Similar letters of reference indicate corresponding parts.

My invention relates to improvements in watchmens time-detectors, by which the printed dials hitherto in use may be dispensed with and plain paper disks be substituted, on which the marks of the stations and the time are quickly printed, with or without colors, by suitable spring devices without the direct action of the keys on the marking parts and a bridge-piece. My invention consists of a rotating steel dial, which has the hour and minute subdivisions engraved in raised figures thereon, and is set in motion by a suitable clock-train. The numbers of the stations are arranged sidewise thereof and marked on a plain paper disk, rotating with the steel dial, by means of strong band-springs with steel marking-plates, which are actuated by the keys at the stations in such a manner that one spring strikes on the steel disk at each station for indicating the time, while the springs for marking the stations strike their corresponding numbers consecutively in the customary manner.

A represents the casing or box of my improved watchmans time-detecter, which is made in the usual style for being securely locked. A clock-train for rotating the central steel dial B is arranged in the body of the easing, while the springmarking devices 0 are attached in suitable manner to the lid D. The steel dial B has the figures of the hour and minute subdivisions engraved thereon, the steel dies E for marking the numbers of the stations being secured sidewise of the steel dial, as many dies being provided as thereare stations to be visited by the watchman. A plain paper disk, B, is securely fastened by means of grooved pins a to steel dial B for rotating therewith, being large enough to extend over the steel dies for marking the stations. The marking devices 0 are made of strong V-shaped steel band-spring 0, provided with small solid marking-plates d and curved or taperin g ends 0, which are arranged sidewise of the barrel-guiding pin f attached to a supporting-plate, f, of lid D, so that the key, when placedv thereon and turned, engages the curved ends of the springs, presses them back, and allows them to strike with considerable force with their marking-plates d on the steel dial and dies, embossing thereby the time and number of stations on the interposed rotating disk. The marking-springs U are placed sidewise of each other, the innermost being stronger than the others and placed above the raised time-figures at the circumference of the steel dial B. All the keys are provided with end wards for actuating this time-1narking spring at every station, while the wards for actuating the station-marking springs are arranged in changing positions thereon for producin g the consecutive action of the same, and thereby the true record of the watchmans visits at thestations. The marks can be merely embossed, as described, or be printed in colors, as desired.

This detecter has this great advantage over the time-checks requiring printed dials, that anybody can make the disks, and, further, that the marks are clearly produced by the instant strokes of the springs without interference with the regular motion of the steel dial and clock-train. Hitherto the marks were made by keys pressing the marking devices on the paper dials and against a bridge, or pressing directly the paper dials against the marks; but paper dials and bridge are by the springmarking of the keys dispensed with, and thereby the usefulness of the tiine-detecters improved to a considerable extent.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. As an improvement is watchmans timedetecter, a rotating steel dial with raised time indicating figures for imprinting on a plain disk the time of visiting any station, substantially as specified.

2. In awatchmans time-detecter, the combination of a rotating steel dial, station-marking steel dies, and plain disk, with strong steel springs with markingplates actuated by the keys at the station for imprinting the time and number of stations on the disk, substantially in the manner and for the purpose set forth.

3. The combination of a marking-spring, actuated by the keys at every station, with a number of station-marking springs arranged therewith, to be actuated in consecutive order as the stations are visited, substantially as described.

4. In Watchmans time-check, the marking band-sprin gs, having striking-plates d and curved ends 0, for being engaged by the keys for striking the marking-dies, as set forth.

The above specification of my invention signed by me this 4th day of August, 1874.

ANTON MEYER.
