UNIVERSAL CLOCK.

v SPECIPICATION forming part of Letters Patent No. 369,462, dated September 6, 1887.

Application filed February 15), 1887. Serial No. 228270. (No model.)

To all whom it may concern:

Be it known that I, SoLoMoNS. MOYER, a citizen of the United States, residing at Allentown, in the county of Lehigh, State of Pennsylvania, have invented certain new and useful Improvements in Universal Clocks, of which the following is a specification, reference being had therein to the accompanying drawings.

This invention has relation to clocks and other time-pieces; and the object in view is to provide a clock of ordinary Construction, so far as the internal system of gearing isconcerned, with additional devices which shall serve the purpose of indicating the time at various desired different points upon the earth s surface.

Another object in view is to provide the necessary devices for indicating the day of the month automatically.

Other objects and advantages of the invention will be hereinafter described, and the novel features thereof will be particularly pointed out in the claims.

Referring to the drawings, Figure l is a front elevation of a combined clock and calendar einbodying my invention. Fig. 2 is a section taken on the line X of Figs. 1 and 3. Fig. 3 is a rear elevation showing the interior mechanism. Fig. 4 represents the new-datecalendar Operating lever depressed by the roller R before that of the old-date calendar, as hereinafter described.

Like letters refer to like parts in all the figures.

A represents any suitable casing or framework, having a glass, A', in the front thereof, and B represents the fixed portion of the dial, and C the movable portion thereof. A crossbar, D, serves, with*a franc, D', mounted thereon, the purpose of supporting the mechanism or gearing employed.

The movable dial C represents the globe, and is divided by lines of longitude C', and upon any suitable line or between any suitable lines of longitude certain points may be selected for the location of loca-l dials, C

Local dials are shown for London, Berlin, Pekin, China, San Francisco, Chicago, and other places in substantially the relative positions that they occupy upon the globe.

The fixed dial B is graduated as at B' to represent minutes of time, as at 13 to represent minutes of time, and as at 13 to represent hours of time. An hour-hand, E, is rigidly connected with the movable dial C, and may be located upon the line of longitude of any desired place, preferably at the place at which the clock is in use. In this ins'tance the hour-hand is rigidly connected with the movable dial and located on the line of longitude of ashington, D. C. A minute-hand, F, moves independently of the hour-hand and moving dial, and with said hour-hand indicates the minutes as the hour-hand does the hours upon the fixed dial B.

It is understood that the minute and hour hands above mentioned are those of an ordinary clock, and that they are to be operated by an internal mechanism exactly like any ordinary clock mechanism. Each ofthe local dials C is provided with a fixed hand, 0 and with a movable minute-hand, CE A scale of degrees, B is arranged on the outer mai-gin of the movable dial and on the inner margin of the fixed dial. This scale may serve to assist in estimating the time at places between and other than those represented by a local dial, C A day-line, 13 is provided. The hour-dial is graduated into twenty-:four divisions, and the fixed dial, as at B 13 B and B indicates the morningfiorenoon, afternoon, and evening, respectively. An opening, B eXposes the indicating-figures of an interier calendar which is set 'for a new date, while an opening B, on the fixed dial exposes the figures of a calendar showing the old date. Now, in order to correctly indicate the time at the several localities represented on the movable dial, it is necessary to establish a relative movement of the hour and minute hands of each of the same with that of the nain hand E, so that-as, for example, taking the local dial for Chicagoit shall indicate a time about one hour later than that indicated by the main hour-hand.

Referring now to Fig. 3, it will be seen that by the mechanisn about to be described such relative movements of the main and local hour-hands and of the local minute-hands can be secured. Upon the movable dial C there are nounted, by means of brackets G, pinions H, in such manner as to be rotated, said pinions being mounted upon the spindles, standards, or shafts H', upon which each of the local minute-hands is Secured. The pinion H has nine teeth. It has been stated that the hour-hands of the local dial are fixed and move bodily with the movable dial and the main hour-hand, so that it is apparent that the local minute-hands must make one rotation while the main hour-hand and the inovable dial move from one to the other of the several honr-indicating figures. This relative movement ot' the hands specified is accomplished by means of a gear, I, which has two hundred and sixteen teeth, and which is fixed by screws l' to the cross-bar D. Now onerevolntion ol' the disk G will cause each of the pinions to travel once over the fixed gear I, thus producing twenty-four revolutions ofeach ol' the minute-hands-thatis, one revolution for each hour-space upon the fixed dial, of which there are twenty-four.

K represcnts the usual minute-wheel, and J the nsual hour-wheel, of an ordinary system of clock-gearing, these being mounted upon a v spindle, L.

M represents an intermediate gear mesling with a pinion, K', cut on the hnb of the gear K. This system ofgearing has its hearing in the l'rame D'and cross-bar D. The usual 'l'rictional contact between the hour and minute gears is maintained by a coiled spring, N, arranged on the shalt L.

The calendar devices employed each consist of a dial, O, mounted on a shalt, O', carrying a ratchet, O, and a 'riction-disk, O, upon which a spring, O", boars for the purpose of stopping a movement of the disk and 'ratchet caused by a pawl, P, which in this instanee is cxtcnded, as shown by dotted lincs P to form a stop-arm, which falls upon a disk similar to the disk but arranged between the ratchet and the dial for the purpose of limiting the (low n ward movement of the pawl. The pawl is formcd 011 or secured to a pawllever, l, pivoted at l in the fixed dial, and in a cross-bar, Q, where also the ratchet and calendar-dial shaft is mounted for rotation. The free end of the pawl-lever l is curved and provided with a projection, as shown at I, (see Fig. 3,) which projection normally stands in a plane parallel with and at the rear of the novable dial O. Upon thelatter is pivotally mounted a roller, E, having two peripheres, ft' 11 the first-that is, the largcr-being adapted during the rotation ol' the movable dial to come into contact with the projection 1 of the pawl-lever, which operates the ratchet connected with the newdatecalendar dial, while the smaller peripheryoperates the pawl-lever and the other calendardial, The roller is located on the movable dial at a point directly under the day-line thereof, so that the calendars are operated at the lower or midnight hour of twelve, the old date appearing in the quarter of the fixed dial marked Eveningfl and the new date appearing in the quarter marked Morning As the roller passes from the projections of the pawl-levers and beyond their pivots, it returns them to a position which causes the pawl to take a new tooth in the calendarratchet, so as to rotate said ratchet at the next passage of the rolleru The cross-bar D is cnt away, as indicated by curved dotted lines, to permit the passage of the braekets G and roller H between it and the dial.

The time required for the dial-lever-operating` rollerltto pass over the bottom levcrs is material, as its movements agree with that of the hour-hand, so that the old-date-calendar level', being operated by the smaller periphery of roller, does not change the indicated date on its dial until after the change of the date on the new-date calendar, and neitheris changed at any other time than when the day-line of the movable dial is at the bottom thereof. This line coincdes with one of the twelveo clock marks, and there being two the calendar dials will be changed only once in twenty-four hours.

From the above itwill be seen that the date shown by the calendar-dial first moved is the new date, while the date shown by the other calendar will be that of the dayjust passed.

Having described my invcntion and its operation, what I claim isl. In conbination with the hour-hand of a clock, a fixed dial divided into twenty-fonr hour-spaces, a movable dial rigidly connected with said hour-hand and provided with local dials, relativel y arranged as described, and each having a fixed hour-hand and a movable minute-hand, a pinion mounted on the shaft of the minute-hand, and a fixed gear having a number of teeth proportioned to those of the pinion as twenty-l'our is to one, substantially as specified.

2. In a clock of the character described, afixed dial having twcnty-four hour-spaces, in combination with moving dial, representing a globe by lincs of longitude, and having local dials arranged on the line of longltude of the localities indicated by said local dials,snbstantially as specified.

In a clock ol' the character described, the conbination of a fixed dial, having` twenty-four hour-spaces, with the movable dial having a day-line, and a calendar-Operating device located snbstantially on the day-line,with a calendar Operating pawl-lcver, which projects into the path of the calendar-Operating device, mounted on the movable dial, substantially as specified,

1-. The conbination of a fixed dial, a movable dial carrying an honrhand indicating spaces on the fixed dial, and carrying a calendar-Operating device, with calendars set one day apart, and having` their Operating pawllevers projected into the path of the calendaroperating devices mounted on. the movable dial, substantially as specified.

5. The conbination ofa fixed dial, a inovable dial having local dials thereon, a fixed gear, and pinions mounted on the novable dial IOO &69,462 3 and Operating the hands of 'the local dials, substantiaiiy as specified.

6. In a clock of the class described, a fixed dial having twenty-four hour-spaces and divided into quarters, indicating morning, forenoon, afternoon, and evening, and calendare openings arranged, one in 'the morning quan te): and the other in the evening quarter, in

conbination With mechanism moving With an hour-hand employed to operate calendars ino dicating dates one day apa't, substantially as specified.

In testinony whereof I affix my si gnaturc in presence of two witnesses.
