' WATUHMANS TIMELRE GISTERL To all whomfit 'ma/y concern: u

Be it known that I, ABRAHAMA. 4NEW- MAN, a citizen of the United States, residing at Chicago, in the countylof Cook and State of Iliinois, have invented certain new and useful Improvements. in Watchmens Timeo'if'. which the following isa speciicatlon.

My invention relates to watchmen-s time-v registers of the general type' described' in my vprior patent No 67,6364', dated June 18, 1901, more particularly to the record sheet orcard and the means for securing the same in operativearelation to the recording"- devices."

In registers of the typerei-'erred to above, I the record sheet is in the form of a disk of paper,` graduated circumferentiallyby radial divisions corresponding to' predetermined time intervals. For example, the disk or dial may be` divided into twenty-four parts, corresponding tothe hours of the' day, and each hour-division may bedivided into smaller divisions eachcorresponding to av certain number of l1nin`utes. vThis dial is operativel' connected-'with' the hour-arbor y of a suita le: clock 'in such manner that the two will rotate in unison, the dial thus making a compieterotation'in'twenty-four hours. The record diallis also arrangedwith' its time graduations inregister Withft-ho'se on. the face of the clock. Recording devices .arelprovided 'arranged in Fixed position relative .to the rotating record-dial and constructed to be actuated by suitable keys to which the watchman has access. The record@ ing devices include a marking'device, for examples die or a`- punch, adapt-ed to make av '4 diemark or a perforationin the. record diall The die-inark or perforation will then indi# l at each insertion and actuation4 of a key.

lent practice so diliicult orv troublesome as toA practically make it impossible.

The invention, which consists in the novel features of construction, arrangements of parts, and combinations of elements hereinafter described and claimed, is shown lin its preferred form 1n the annexed drawlngs 1n which: v

Figure 1 is infront View of the record-dial and the devices for securing it in position,

part of the latter devices being broken away.

Fig. 2 is a vertical cross section of the same. Fig. Sis a section on line III-Blot Fig. 2. Fig. 4t is a pian view of the record-dial, but showing only a portion of thetime-graduations.

The circular plate 1, Fig. 2,. is the member which supports the record-dial, 2,' and is provided wth a neck or tubular stern 3 adapted to fit tightly the hour-arbor of a clock or some other suitable arbor rotating in unison therewith.. The plate 1 is preferably permanently fixed to its arbor in any convenlentmanner not shown.

' Rigidly fastened on the plate 1 around 'the neck or stem `3 is a member 4 having projecof a correspondingly 'shaped aperture 5 in -the center ofthe record-dial. This member is preferably shaped like a spur or gear- Wheel,V as shown, with, say, twelve'teeth. The engaging member 4- thus engages the dial at a' number of points and by thus distributing the strain on the paper lessons the liability of the paper to tear.

` AOver thef toothed engaging member .4 is aflat cap 6, having on its under side acircuiar recess 7 to recelvethe said member. The c ap has a short neck-portion 8 surmounted- Iby a finger piece 9 which may be conveniently grasped for removal of the cap. To

yretain the cap removably in position an alic- -tions from its periphery to engage the edges shapedspring catch..10 is provided,.rigidlyA i fastened to the cap at oneend, as by a screw 105, and having lts other end formed with an inwardly extending inger 11. The finger is rounded at its end and extends into a {rounded'groove 12 in the neck 3 of the supporting piate 1, the neck of the cap' being cutaway to permit the' iin er 11 to enter its groove; A firm .pull on t e nger piece 9 will cam the spring-nger out of its groove,

"' thus'releasing the ca p, while-a rm push in replacingthe ca p wi outwardluntil t e 1- first spring the finger .upperor outer lip of the v12 in4 replacing the cap a stud 13 iis' groove'is cleared. The .various parte are preferably so pro ortioned that' vWhen inf position the cap wil bearwith'some firmness" on the record-dial and therefore hold the f same firmlyagainst the plate 1. In 'orderA to linsure register of the -nger ll-'and-groove vided, extending from the fixed end Aof the spring into a notch'or slot 14 inthe top' of. the neck 3'. lThus the'- cap cannot be "pushed down into place until the stud and.-

, notch are in register and consequently. the

.fin

r 1]. and groove 12 also. y the devices above described the record.- dial isheld securelyl on the rotating part.

.At-the same time, it isevident that only a record-dial. whose central aperture correspends in sine and shape exactly with the toothed enga ingmember 4' can be successfully used. 'Ihns if the attempt is made to placca dial with a differently shaped open- 'in on the latev the replacement 'of the cap w1 l 'cause t e edges of the dial aperture to be torn or crump takable and ermanent evidence o the im. proper use. ghe considerable number of the teeth on the member 4', and their uniformity' also, are im rtant,-'though not indispensable, features.

Vhile properly apertured dials ycan with, suitable dies or similar tools bemade very easily, it is a most tedious operar' tion to cut the required a ertures by hand...- In fact, cuttin the teetli'lb y necessary *reguI arity and uniformity is so troublesome and tedious as to be prohibitive. The number of teeth, and their size, etc., canbe varied indeiinitely.- In fact it, is desirable to make the retaining member 4' diii'erent, as to number of teeth, or their size ,or shape, etc., for each clock, thus effectul allypreventing a Wntchman fromv using` in his own clock record-dials which were made foranother clock and of which he may have surreptitiously obtained possession. It will there ore be seen that my invention possesses marked utility inA that .it not only furnishes effective means for securing the record-.dial in operative relation -to the c lo'ck and the recording devices, but also provides protection against;v fraudulent use of improper dials.

What -I claim is:

1'.` In a time -register, the combination of.

an engaging member having angular peripheral projections, 'adapted to be rotated bya clock-driven arbor, a' record dial a central aperture provided 4with angular in` dentations correspondingi'n size an proed, thereby .givin nnmishand with, the

practically having Icontea e. former member with a c1ock-drivenarbor jan engaging member rigidly secured to t former member and having uniform peripheral projections, adapted to receive n' suits. 1y apertured record-dial, and means for retaining the dial in position.

. 4. In atime-re 'I ,the combination ofa supporting mem having a tubular neck adapted to fit over aclock-driven arbor, an engagin member having' vrigid connection with said neck and concentric therewith,y

said engaging member being providedwith .uniform p'ro'ections from its periphery, and a cap vremov'a member.

5.4 In a time ster, the combination of a supportingmem r having a tubularneck adaptedto-fit a clock-driven arbor, an engaging member in rigid conection lwith said neck, and-a cap covering said engaging memlyseated over said engaging ber and vhaving a catch yieldingly engaging l said neck.

6. In a time-re 'ster, they combinationA of a supporting plate aving a-tubularneck, and 'a toothed engagi x'nember concentric with isI the said neck and 1n rigid connectionthere.- l

with.

7. In a time register, the' combination of a supporting plate'havin a tubular neck, an engagingxmember rigi ly mounted on the said plat-e -concentrically with the neck.' ,thereof and provided at its periphery with uniform engaging teeth, a cap having a re- Icess to receive the engaging member and a central. aperture i to receive the said' neck,

and a finger piece surmounting the cap and.

having a sprin catch ieldingly enga the said neck w ereby t Ae cap may be 'mard- 'ily removed and replaced.
