To all 'whom it may concern.'

Be it known that I, EMANUEL AUFIERO, a citizen of the United States, residing at Brooklyn, in the county of Kings and State of New York, have invented certain new and useful Improvements in Timepieces; and I do declare the followin to be a full, clear, and exact description o the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to improvements in watches, clocks and the like.

The obj ect of the invention is to provide a timepiece having means for indicating lthe standard or local ltime at different longitudes.

With this object in view, the invention consists of certain novel features of construction, combination and arrangement of parts as will be more particularly described and particularly pointed out in the appended claims.

In the accompanying drawings, Figure 1.

is a side view o a watch constructed in accordance with the invention; Fig. 2 is a sectional view On the line 2 2 of Fig. 1; Fig. 8 is a plan view of the two stationary dials of the watch; Fig. 4 is a similar view of the revolving hour dial and Fig. 5 is a similar view ofthe revolving minute dial.

In the embodiment of the invention I provide four concentrically arranged dials, two oi which are stationary, and two revolving. On one of the stationary dials is indicated by numerals of reference how many minutes a certain city is east or west of a given standard hour meridian. On the other stationary dial is indicated the names of the principal cities of the world. On one of the revolving dials is indicated an hour scale, and on the othler revolving dial is indicated a minute sca e. f

The central stationary dial'i is divided into equal parts by twelve radii, and the dotted circle p divides each radial line into two parts.

The parts of the radial lines within the circle p represent the twelve standard meridians of west longitude, and the parts of the radial lines on the outside of said circle represent the twelve standard meridians of east longitude. As shown in Fig. 3 of the drawings, each of the radial lines is provided with a numeral which indicates the counting value of said line. The international meridian of Greenwich may berepresented by the radial line on which London 1s written. The

radial line numbered 1 next to the left of the London line indicates one hour east of Greenwich; the radial line numbered two indicates two hours east of Greenwich, and so on. As illustrative of this, Rome which is one hour, standard time, east of Greenwich is written on the line 1.

The radial line numbered 1 on the right of the Lon don meridian indicates one hour west of Greenwich; the line numbered two reads 2 hours west of Greenwich, and so on. As an illustration of this, Washington, which is ive hours west of Greenwich is indicated on the line 5 within the circle p.

The names of the cities are written on that hour line, the longitude and time of which is nearest to or exactly the longitude and time of the said city. To each of the cities of which the time is not exactly represented by the hour line, is annexed a reference numeral which is reproduced on the stationary dial, j,

as shown. This reference numeral indicates the number of minutes the said city is eastor west of the hour meridian. The names of the cities on the inner stationary dial are written across the hour lines which pass through or between the central letters of the city, so that one-half of the letters of the city are on one side of the line, and the other half on the opposite side.

The annular stationary dial j is divided into sixty equal parts or minutes, of which thirty are on a white background, and thirty on a light blue background, the latter being indicated in the drawings by dia onal shade lines. The arrow head, n, whic separates the white half from the blue half of the dial, is arranged in line with the London or Greenwich meridian line of the inner stationary dial. One minute east of any standard meridian indicated on the dial i is represented by the division mark or next on the left of the arrow head, n. The second division indicates two minutes east and so on untilthe thirtieth division on the white half ofy thedial is reached. In the same manner the divisions or minutes are counted on the shaded or blue side on the right of the arrowhead, n, the division mark annexed on the right of said arrow head indicating one minute west, and the second mark two minutes west and so on.

As hereinbefore described, the number of references annexed to a city is reproduced on the dial and its position thereon indicates the number of mintues the said city is east or west 'of the `hour meridian on which the city is written. As an illustration, the number 8, which is annexed to Buenos Ayres is reproduced on the seventeenth division of the dial j to the left of the arrow head n, and is read seventeen minutes east or ahead of the hour meridian on which said city is placed. The number 6, which is annexed to Singapore, is reproducedon the fifth division on -the shaded or blue half of the dial, and is read liveminutes west or past the hour. The outer stationary dial has arranged thereon, adjacent to its outer edge, a series of arrow heads, which indicate continuations of the meridian lines on the dial i. l'I he inner dial i and the outer concentrically arranged annular dial j are spaced apart and connected together by radiallyT projecting bars, k2, as shown in Fig. 3 thus providing between saiddial an annular space, 7c3, in which the inner revolving dial is adapted to rotate. Formed j on the outer edge of the outer annular dial sleeve c of the movement.

are radially projecting bars, c by means of which said stationary dials are firmly secured to the casing of the watch. The outer revolving dial d incloses the stationary dial and revolves around the same. On the dial d is arranged Romain numerals from one to twelve, said numerals being disposed reversely to the position in which they are usually placed on the face of an ordinary clock or watch. Any suitable form of time piece movement may be arranged in the casing of the watch to operate the movable dials therein. The dial d is mounted on the hour sleeve c of the movement, which is indicated by the reference letter M in Fig. 2. The dial d is adapted to turny from left to right with the The revolving minute dial b is fixed to the minute shaft of the movement and turns therewith so as to make one complete revolution for each hour that the dial d moves. The dial d is arranged and turns in the space 7c3 between the inner and outer stationary dials, and is divided into sixty equal parts or minutes, of which thirty are designated by black marks, or lines, opposite every iive of which is laced a black indicating numeral. The ot er thirty divisional lines of the dial are designated by lines or marks upon a blue background, which is indicated in the drawings by diagonal shading. Opposite every ve of these divisional marks is placed a numeral.- The numeral sixty is placed on the division line separating the white half of the dial from the shaded half. The numerals of each side of the number sixty begin with ive and increase up to thirty, which numeral is arranged diametrically op osite to the numeral sixty, as shown. At t e beginning of each hour, the numeral sixty on the dial b is coincident 'with the arrow head fnl ofthe outer stationary dial The dials employed in connection with my invention may be constructed of Celluloid, smelted copper, or any other suitable material, and as hereinbefore described, may be connected with and operated by any suitable time piece movement. In order to cause the greatest contrast between the different cities on the various meridians, I prefer to print such cities in different colors, as red, green, blue, yellow, etc., using the same color for all cities belonging on the same meridian. The arrow heads on the dial are also printed in the same color as the meridian to which they correspond.

In reading the device to ascertain the time of such cities which have no annexed reference numeral, the minute sign on the dial l) nearest to the arrow head n is read; if said minute sign is on a white ground, read the h'our on the dial d, which has just crossed or passed the hour mark or arrow head of the city, the time of which it is desired to find. If the minute sign nearest to the arrow head fn is on a blue ground, read the hour on the opposite side of the arrow head n or about to cross the same. When it is desired tov find the time of the cities to which reference numerals are annexed, read on the minute dial b the minute sign nearest to the division on the dial y' having reproduced thereon the numeral which is annexed to said city, this division being for the sake of reference called the minute point77 of the city, the minute point of a city having no reference numeral added is the arrow marked London In all cases when the minute si n on the dial opposite the minute point o a city is on a white ground, read the time of that city as so many minutes past, or after the hour.

'Ii a minute sign is on the blue ground, read the time as so many minutes to or before the `hour. The hour is found as follows: First. When the minute point of the city is on a white ground, ifthe minute signs opposite,

the minute point and opposite the arrow marked London7 are both on a white ground, the hour which has just crossed the hour meridian of said city is read; if not, the hour which is about tov cross is read. Second. When the minute point is on a blue ground, if the minute signs opposite the minute point and opposite the arrow marked London are both on a blue ground, the

hour about to cross the hour meridian of the city is read; if not, the hour which has just crossed is read.

The ante meridiem or post meridiern time is determined by the meridian, thel time of which is known, and the rule to be followed ,is to count Jfrom the meridian nearest to the hour 1 to the meridian nearest to the hour twelve, the longitude being changed by crossin the meridian of Greenwich, except when t e hour twelve is precisely on lthis meridian. For instance, at Washington it is six oclock, post rneridiem. The longitude hour on the dial d to the meridian of Green- Changing of Washington is west, therefore, the western meridians from the meridian nearest to the wich read post meridiem time. longitude, the -eastern meridians from the meridian of Greenwich to the meridian nearest to the hour twelve read post meridiem time. The other twelve meridians read ante meridiem time.

From the foregoing description, taken in connection with the accompanying drawings,

lthe construction and operation of the invention may be readily understood without requiring a more extended ex lanation.

Various changes in the orm, proportion and the minor details of construction may be resorted to without departing from the principle or sacrificing any of the advantages of this invention as defined in the appended claims.
