PORTABLE WATCHMANS CLOCK.

Specification of Letters Patent.

Patented July '7, 1914.

Application filed March 31, 1913. Serial No. 757,838.

To all whom it may roncern Be it known that I, O'r'ro E. HAUsnUno, a subject of the Emperor of Germany, residing at New York, in the county of'New York and State of New York, have invented certain new and useful Improvements in Portable "Vatchmens Clocks; and I do hereby 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, reference being had to the accompanying drawings, and to characters of reference marked thereon, which form a part of this specification.

The present invention has reference, generally, to improvements in portable watchmens clocks used to control and report the movement of watchmen; and the invention relates, moreparticularly, to the means connected with the clock mechanism for operating the report dials placed in said clocks.

In the manufacture of watch-mens clocks as heretofore practiced, it has been the custom to make such clocks in two types, viz: those which operate a twelve hour report dial, and those which opcrat-ea twenty-four hour report dial. In the clocks of the former type, the report dial carrying device was connected directly to the arbor of the springbarrel which furnished power to the clock mechanism, this spring-barrel being adapted to .make one complete revolution every twelve hours. In the clocks of the latter, or twenty-four hour type, the report dial carrying device was also connected directly to the arbor of the spring-barrel, but in order to reduce the revolution of the springbarrel to one revolution every twenty-four hours instead of every twelve hours, which was neces ary to effect the proper movement of the report dial, it required the addition in the clock movement of an extra wheel and pinion to gear down or slow the spring-ban rel with reference to the escapement of the clock movement. The addition of this extra Wheel and pinion in the clock-movement rendered necessary a much stronger main-- spring in the spring-barrel, with consequent evils attendant thereon.

The present invention has for its principal object to provide in connection with the ordinary clock-movement of watchmens clocks an interchangeable means for operating either a twelve hour report dial or a twentyfour hour report dial, without the necessity -movement t be touched.

of changing the ordinary construction of said clock-movement, or in other words, obviating the use of an extra wheel and pinion, and heavy main spring in the clock-movement, thereby rendering the clock easily and quickly adapted for use by a day watchman and night watchman, whose movements are reported on a single report dial, or if desiredby separate report dials, the change of report-dials and the means for operating the same being easily and quickly made without in any way requiring the clock- Therefore in the novel watchmans clock embodying my invention the train of the clock movement consists of a spring-barrel, 2nd, 3rd, 4th wheel and pinion, and then the escapement, whether the same operates a twelve or a twenty-four hour report dial, and the opera tion of the twenty-four hour report dial, does not require a clock-movement train consisting of a heavy spring-barrel, 2nd, 3rd, 4th and extra or 5th wheel and pinion, and then the escapcment as has heretofore been necessary.

Other objects of the present invention, not

' at this time more particularly enumerated,

will be clearly understood from the following detailed description of my present invention.

\Vith the various objects of the present invention in view, the same consists, primarily, in the novel report dial operating mechanism for watchmens clocks hereinafter set forth; and, furthermore, this invention consists in the several novel a rrangements and combinations of the various devices and parts, as well as in the details of the construction of the same, all of which will be hereinafter more fully described in the following specification and then finally embodied in the clauses of the claim which are appended to and which form an essential part of this specification.

The invention is clearly illustrated in the accompanying drawings, in which Figure 1 is a front or face view of the novel construction of watchmans clock made according to the principles of my present invention, the lid of the case being open, and a twenty-four hour report dial being operatively connected with the clock. Fig. 2 is a face view of the clock-movement removed from the case, and the report-dial also removed. to illustrate the carrier-disk and guard-ring which lies beneath said re- I port-dial.

port-dial; and Fig. 3 is a similar face view with said guard-ring removed to illustrate a part of the means for driving said carrierdisk when a 24 hour report-dial is connected' therewith. Fig. 4 is a part section and part side elevation of said clock-movement and the means connected therewith for driving or operatin said 24 hour re- Fig. 5 is a detail vertical cross section of said 24 hour report-dial driving means, the same being drawn on an enlarged scale. Fig. 6 isa'detail bottom view of the driving gear of said carrier-disk, illustrating particularly the means for securing said carrier-disk thereto in driven relation, but nevertheless permitting an in dependent rotation of said carrier-disk for setting the report-dial at the proper hour when the clock is delivered to the watch man. Figs. 7 and 8 are, respectively, similar to Figs. 3 and 4, but illustrating the operative connection with the clock-movement of means for operating and carrying in the clock a 12 hour report-dial; said views showing the interchangeability of the clockwith reference to the use therein of either 24 or 12 hour report-dial.

Similar characters of reference are employed in all of the above described views to indicate corresponding parts.

Referring now to the said drawings, the reference character 1 indicates a case in which the clock mechanism is contained, said case having a lid 2 and a suspending ring 3, and being further provided with a lock 4 adapted to be engaged by the catch 5 connected with said lid 2.

The reference character 6 indicates the frame in which the clock-movement and report-dial transmission is mounted, saidframe being provided with a top-plate 7 and a bottom-plate 8. Journaled in said topplate and said bottom-plate is the arbor or spindle 9 of a main-spring barrel 10 which provides the motive power to the clockmovemcnt and reportdial transmission. Said spring-barrel 10 is provided with gearteoth 11 which transmits thespring power to the gear and pinion train of said clock 'movement and to the 24 hour report-dial transmission devices. The said spring-barrel makes one complete revolution in twelve hours, or two such revolutions in twenty-four hours, therefore, when it is desired to use a 24 hour report-dial which makes one revo lution every twentyfour hours, thecarrier- 'disk cannot be connected directly to the arbor or spindle 9, as can be done when a 12 hour report-dial isused, hence the following 24 hour reportdial transmission mechanism is provided so that the carrierdisk is revolved once upon the completion of two revolutions of said spring-barrel 10. This mechanism comprises a carrier-disk 12, the hub 13 of which is loosely journaled views upon the upper end of said arbor or spindle 9, so as to turn freely thereon and independently thereof. The lower end 14 of said hub 13 of said carrier-disk12, which projects beneath the under side of said our rier-disk, is provided with an annular groove or channel 15. Secured upon this lower end of said hub 13 is a driving-gear 16, the under side of which is chambered as at 17. A U-shaped spring friction key 18 is provided, the legs of the same entering said groove or channel 15 of' said lower end of the hub 13, and the body of said friction key bearing against the under surface of said driving-gear 16, thus securely, by its frictional binding engagement with both said groove or channel 15 and the body of the driving-gear 16, uniting said drivinggear 16 with said carrier-disk 12, so that when the former is rotated thelatter will be driven thereby to rotate therewith, and yet such connection permits the independent turning or rotation of said carrier-disk 12, when the frictional engagement is overcome, for the purpose of adjusting a reportdial carried by said carrier-disk 12 to its proper starting position when inserted in the clock. Fixed in said carrier-disk 12, in

proper positions, are a pair of connectingpms 19, which project upwardl from the upper surface of said carrier-dis 12. Said connecting-pins are adapted to pierce a 24 hour report-dial 20, and thus connect the same immovably with relation to said carrier-disk so that it will be rotated by the movement of the latter. Said report-dial 20 is removably retained in such operative connection with said carrier-disk 12 by means of the washer 21, said washer 21 being provided on .its under side with receiving-sockets 22 for the reception of said connecting-pins 19. Said washer 21 is further provided with a knurled finger-piece 23 whereby when said washer is turned the movement is transmitted through said connecting-pins 19 to said carrier-disk 12 so that its independent report-dial adjusting or setting movement, above referred to, may be attained.

The reference character 24 indicates a guard-ring which is provided with a centrally disposed opening 25 through which the said carrier-disk is presented for the reception of said report-dial 20. The underside of said guard-ring 24 is chambered, as at 26, to provide a space in which said driving-gear 16 is located. Said top-plate 7 is provided with a hatch 27, and said guard-ring 24 is also provided with a hatch 28 registering above said hatch 27. Through these hatches 27 and 28 the key operated stylus-points 29 gain access to the report-dial 20 for registering thereon the watchmans record of movement or patrol,

all in the usual and well known manner.

Secured upon said top-plate 7 is a block 30 the pointer-arm 31 of which projects over: the upper surface of said report-dial 20, and serves as a dial setting register, and also as a looking for holdin the dial during the registering or mar ing operation of said stylus-points 29. Secured to the said bottom-plate 8 is a bearing bracket 32 in which is journaled thelower end of a spindle 33, the upper end of said spindle 33 is journaled in a bearing perforation 34 provided in said guard-ring 24. Secured .to said spindle 33 is a gear-wheel 35 which meshes operatively with the teeth 11 of said spring-barrel 10. Also secured to said spindle 33 is a pinion 36, which projects through an opening 37 in said top-plate 8- so as to be positioned to mesh with the teeth of said driving-gear 16. The said gear-wheel 35 and pinion 36 provide a reduction transmission gearing whereby the rotation of said spring-barrel 10 is transmitted to said drivmg-gear 16, and consequently said carrier-disk 12 and the report-dial 20 carried thereby, so that the latter parts will make but one revolution to two of said spring-barrel 10, that is to say, that said report-dial will be rotated completely once every twenty-four hours.-

Of course, it will be understood that the number of teeth of the respectivegears and pinions may be varied while still retaining the proper reduction ratio, I have found, however, the following specific relation of gear-teeth to be well adapted to provide the result sought; viz., 90 teeth on the springbarrel 10, which is the usual provision for operating the ordinary clock-movement, the gear-wheel 35 is then provided with 30 teeth, hence the spindle 33 turns three times to one turn of the spring-barrel 10, and consequently the pinion 36 turns three times also, said pinion 36 is then provided with 15 teeth and meshes with the driving-gear 16 which is provided with 90 teeth. Since the spring-barrel 10 rotates twice in 24 hours, the spindle and pinion 36 will rotate six times in every 24 hours, and since the pinion 36 has 15 teeth and meshes with the driving-gear 16 having 90 teeth, it follows that the six revolutions of said pinion 36 will produce one revolution of said drivinggear 16 and consequently of the 24 hourreport dial and its carrying means. This operation is attained by the use of the ordinary clock-movement and spring-barrel, and obviates the necessity of inserting in the clock-movement itself an additional reduction wheel and pinion which would then render the clock-movement and spring-barrel inoperative" for'use with a 12 hour-report-dial.

As illustrated in Figs. 7 and 8 of the drawings should it be desired to use in the clock a 12 hour-report-dial, I remove the carrier-disk 12 and its driving-gear 16, and

place upon the upper end 14 ofsaid arbor or spindle 9,. a carrier-disk 38 which is adapted to frictionally' engage said upper end 14 of said arbor or spindle 9, so as to be driven directly thereby. The 12 hour report-dial 39 is now connected with said carrier-disk 38 and secured thereto by the connecting-pins 40 and the washer 41. Now

said carrier-disk 38 isrotated by said spring-barrel 10 and its arbor or spindle 9 directly once in every twelve hours, and said spindle 33 with its gear-wheel 35 and pinion 36 merely run idly. It will thus be apparent that my novel construction of watchmans clock is easily and quickly interchangeable for 24 or 12 hour report-dials without disturbing the clock-movement or spring-barrel, and that this result is attained by reason of the novel combination with the spring-barrel of the novel transmission means for 24 hour report-dials above described.

I am aware that some changes may be made in the various arrangements and combinations of the several devices and parts and in the features ofmy present invention without departing from the. scope thereof as described in the foregoing specification, and as defined in the claims appended hereto. Hence, I do not limit my invention to the exact arrangements and combinations of the various devices and arts as herein set forth, and as illustrated in the accompanying drawings, nor do.
