To all whom it may concern: Y

Beit known that J. BEK, of Schwenningen, in the Kingdom of Wrtemberg, did invent a new and useful Improvement in Watch- 1 coverhaving been removed 4to expose `ing parts. Fig. 3 is a side elevation of this is an elevation ofthe -face view of the `piece mens Time-Detectors; and that the following is a full, clear, and exact description there-v of, which will enable others 'skilledin the art to make and use the same, reference being had to the accompanying drawin' ,forming part of this specification, in whichl cwingv Vj; ,l Figure 1 represents a face viewof this invention when closed and read' for operation. Fig. 2 is a. plan or face view o the saine, the the work-- invention, the case having been cnt open to expose the working parts.` Fig. 4 is a verti cal central on of the same. Fig. o is an elevation of t e several keys which used for operating my watchmans control, Fig. 6 key used for setting the Fig. 7 is :typlanv or of paper'- which 'givessu account of the circuit of the watchman.

It is placed in the hands of the watchman locked, just before he starts on'his beat, and on his return he gives it back to the superintendent or supervising oihcer, who, on opening the same', can iind recorded or indicated the precise time when the watchman has visitedl the several stations to be visited on his beat,I which direction he has taken, in which order he has visited the several stations, what delays and deviations have occurred, how long he has tarried on the way between the several stations and on the stations themselves, &c.

of a paper or other suitable material, and marked oil' into a convenient number of parts to represent hours of the d'ay, in combination with a chronomet/er `or other time-piece and one or more marking devices, for marking said movable strip 'ofpaper or other material, in such a manner that by the marks produced in or on the movable strip the time when the 'watchman has visited the stationk or stations is recoiricd,.and 'can be ascertained ety any tii'neA after the watchman has completed .his round, tripof paper partaking of the made `to revolve with it. 1f Amuy one'V station nemmeno or the device for tuting the piercing-instrument bestationary but when more menons-stt en' n included in the beet of a, watchman, different keys used for actuating thcpiercinginstrumen j are iir'xnly secured, one at station, and the watchman carries the' chronome'ter or watch from one station to the other, and bAV station the pic n g-instrumentsare actuated and the indenitatiioncl produced, which form ay record of the tune' when h hsspassed such staton or stations.

In this nvcntion the stri of peper is upon adrum or suriisoe,.which s cmxneoted with the watch so as to partake of its' movement.

l over the hour-hand in suchfa manner that said drum is caused to rotate once-in twelve hours with the hour-hand. It is retained in its place by a bar, b, which is hinged to a post, c, on one side of the dial, and which is secured by a spring-catchy@ oir the opposite side, and a pin,.e,'which projects from-the lower surface of said bar into a central opening-in said hub of the drum, serves to keep .the same steady during its motion. Beyond the drum, and' secured'to the face-plate of the watch, which is somewhat larger thanv said drum, are arms containing a series of 'spring marking-points, B, one above the other. ASaid points are turned toward the circumference. of the drum, and

they stand exactly oppositethe figure XII on'` the dial of the'watch. Close behind. these spring-points, and rmly fastened in the facefplate, is a pin, f, that receives the several keys C which serve to operate the springs.. The whole is covered up by the coverD ofthe case E, .and a small'lock, which is attached to the inner sidepf the case, serves to fasten said cover. i.

. lIf a strip of paper or other suitable material is now wound around the drum A, and if one orv more of the points are forced up against lthe circumference of saiddrum by one of the keys C, which are inserted on the pin f through a suitablev key-hole, c, in the cover D, small holes are producedl in said movable strip of paper or other material` by the action of the points. The circumference of the drum is pro-1 vided with grooves corresponding in number to the spring-points, and just opposite to the same, so that the space. below'those portions of the paper which are to be penetrated ,by the points is. hollow, land thepoints can pass through the paper without becoming injured.

The strip of paper. F is divided intol twelve hoursv` and into the required parts of hours by lithographieprinting, and it is retained in place by a small point projecting from the face of the drum. The division on vthestrip of paper in-this example goes lfrom 6 to 6, (see Fig. 7 9) but it may commence or end'with any other hour, as maybe desirable. lIn placing the strips of paper on the drum, the dot in` the'figure 6 on the blackend of the paper is pressed on the point of the drum, which is provided for retaining them in .place, land the strip of paper is drawn from-*left to right,

thereby bringing the dot'in the ligure6 at the 'white end of the paper alsoon the point of the n drum. The number of the marks produced on he y strip of paperl depends entirely upon the rm ofthebit of the key, for if this bit is so .arranged that the same .depresses one, two,

three, four, Src., ,spring-points, an equal num,-v ber of holes is produced on the corresponding places of the paper.'- f I Y For convenience `and facility in reading o' the record of marks produced on thestrips of v paper, said strips are colored 'red at their under sides, and are pnoyidedwith gum or mu cilage for the offastem'ng them; `into ebook, and, ,as they are made moist for lthis l g, inserted in its side.

purpose,`the red color penetrates through the holes','and makes them appearperfeetly clear and distinct on the upper surface of the paper.

`The operation will be easily understood.

In the beat of the watchman a number of stations are selected whichare to be visited regularly by the watchman at every hour, or at certain fixed intervals. stations a small closet is provided, .in which is secured, by a chain or any other desirablev means, one of the vcontrolling-keys C. Such chain is attached in the interior o f the closet vin lsuch a manner that the key cannot be taken away. f.

l -rlhe watch. is perintendent, and a fresh strip of paper is fastened to it, and then the watch is locked. The key for opening the watch remains in the hands of the superintendent. In this state the watchman receives the watch, and all yhe has todo is, on reaching the several stations, to take thekeys fastened in thesame, insert them into the key-hole in the cover of the case,

' and turn them so as toforce the springpoints through .the paper at their respective spots.

The number of the' marks produced by the spring-points can be made to correspond to the'number'ofthe stationson the first station, one hole o'n the-second, two; on the third, three, and soon, if the number of the stations does not exceed that of the points.v If the numberof the stations exceeds that of the points, they can be marked on the strip of pavpersfby various combinations of thepoints `Without changing in the least the construction ofthe apparatus. 5 e f .Y iSix spring-points will be suricient for a large number of stations, as it is not necessary -to' designate a great many stations, since a ysmall' number of ystations can' be selected, so as to compel the .watchman to pass over the `entire beat in going his round.

` It is still of no'small advantage to 'be able. to use the same/watch for la large number of Vstations,.since its use is not restricted to' sin! -glehouses manufactories, or towns; but it may be used with advantage on l post-routes and railroads.'

At the end of the day the watch is returned to the'superintendent. -He opens it, takesout the movable `stripv of paper,replaces it by a new one, winds up the watch, setsitif necessary, locks it, andreturns it to the next watchman. On the movable strip of paper hev iinds everything marked as hereinabove stated; yand if it 'is desired to know how long the .watchman has tarried at each station, it is only necessary. to order him to turn the respective keys at the moment he reaches each station,'and again 'just before leaves the same.

For the purpose of setting 'the watch the same key'is used whichv serves to wind it up..`

This key is represented lin Fig. 6 of the draw'l: ing; and it will be noticed that itv has a ping minute-hand of the w In, each. of these wound up every day by the su- This pin representsiha; l atcb,- nd kQyS-Brf 'serted in the central arbor ofthe'iwatchfso that said' pin g corresponds with the position of the minute-hand, and it is now turned until it corresponds with the proper 1 figure to designate the correct time. y

The principal advantage of this device is that it can be carried conveniently' in the pocket. Its construction is extremely simple and durable, and it can be made and sold at a reasonable cost. It is arranged so that the same watch can be used for any number of stations without changing its construction or rendering it more complicated. It can be placed in-the hands of themo'st awkward watchman, since. it makes no diiierence in what direction or how often the keys are turned. It is very `easy to prevent an imitation or forging of the keys by the watchman, sim. ply by changing the keys sometimes without per, and it enables the superintendenttokeep a continuous account of the manner in which the watchman performs his duty by pasting the several strips of paper on the leaves of a book kept for that purpose.-

l Having thus fully described this invention, what isclaimed as new, and desired to be secured by Letters Patent, is-

1. The drum Acarrying a removable strip of paper or other suitable material,- marked or divided oi in a convenient number of parts,` in combination with a chronorneter-movement or time-piece, and with one or more marking devices, substantially as and for the purpose set forth.

2. The combination of the marking device B, fastened internallyto a time-piece, with a watch-movement, and with a series of keys, C, and a surface for receiving,` marks, substan tial1y as described. l the knowledge of the watchman. It gives the means to read 0E the correct account of each station by takingy out the movable strip of pa- JACOB E. Burials Witnesses:
