GEORGE BLANCHARD, OF NEV YORK, N. Y.

CALENDAR-WATCH.

SPECIFICATION forming part of Letters Patent No. 340,855, dated April 27, 1886.

Application filed January 12, 1886. Serial No. 183,206. (No model.) I

.To @ZZ whom, z may concern:

Be it known that I, GEORGE BLANCHARD, a resident of New York, in the county of New York and State of New York, have invented eertainncw and useful Improvements in Time- Pieces,v 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 pertains to make and use the same.

My invention relates to improvements in time-pieces, and especially to improvements in that class known as calendar77 time-keepers, in which the dial is marked with a series of figures representing the days of the month, and a suitably-actuated hand or index passes from one iigure oi' the series to the next succeeding iieure at the close of each day.

The object ol' my invention is to provide a simple and practical meansby which the hand which indicates the day of the month on a dial marked as described may at the same time indicate the day of the week; and the construction, application, and opera-tion of theinvention are fully described and explained in this specilication, and shown in the aecompanying drawings, in which- Figure l is a plan of a time-piece provided with the improvement constituting` my invention. Fig. 2 is a similar view with parts broken away to show construction; Fig. 3, a section ol'the ease or shell and bezel of the time-piece shown in Figs. l, 2, the plane of section passing through the line a" y, Fig. 2. Fig. fl is a section, and Fig. 5 is a plan, of a bezel provided with an auxiliary ring, eonstituting a modified form of my invention. Fig. 6 is a plan of a bezel marked on its outer in stead ofits inner bevel.

In these views, A is the dial, B is the bezel, and C is the case or shell, ol' a watch of ordinary construction, the dial being marked with a series et' numerals, from l to 3l, indicating days of the month, and the bezel being formed with an outer bevel, B, an inner bevel, B', and an annular llangc, B, by means of which it is fastened to the case, all of which features are common and well known.

Y rlhe watch is provided with a hand or index, l), which is actuated by any ordinary and well-known form of time-keeping mechanism, and passes each day from one number of the series on the dial to the next succeeding number, and thus indicates the day of the mouth. As this hand or index is old in combination with a dial such as I have described, and as the mechanism which actuates the hand con- Stitutes no part of my invention,no such mech anism is illustrated or described.

The bezel B, which may be rotated with reference to the case O and dial A, has on its inner bevel, B', next to the dial, a series of characters indicating the days ot' the week, these characters being either the initial letters of the seven days of the week, or a series of numerals, from l to 7, repeated as often as may be desired, or a series of dots or lines, or any other arbitrary characters, the object of these characters being to indicate the weekdays eorrespondingto the days of the month marked on the dial. rllhespacing of the characters on the bezel necessarily corresponds with that oi' the numbers on the dial, and whatever' may be the form or nature of the charactersmarked on the bezel, it is preferable that they be in some waydividcd into sets o1" seven, especially if they be merely dots or lines or other similar marks, such division being indicated in Figs. l, 2 by radial lines extending across the inner bevel, B, ofthe bezel.

The bezel is held in connection with the case by means ol' screws hl E, set in the ease at points directly opposite cach other, the Shanks of the screws beingjust inside the inner margin of the flange B of' the bezel, and their heads being adapted to extend over thcilange and prevent its disengagement. The inner margin of the iiangc B" is broken by two oppositely-placed notches adapted to pass the heads of the screws E E when the bezel is brought to the position shown in Fig. 2. The notches being passed over the screw-heads, the bezel may be rotated into the position shown in Fig. l, the direction of rotation being indicated by the arrow in Fig. 2. As soon as the bezel is rotated from the position shown in Fig. 2, the screw-heads overlap the ilange B, and thus secure it to the case, and it is evident that when the bezel is removed from the case the screws may be so setas to secure IOO any desired degree of friction between the bezel and case. Since the bezel when in position on the case hides the screws E E, I have formed on the bezel and case, respectively, notches F F', so placed as to register when the bezel is in the position shown in Fig. 2-that is,when the notches in the flange B are in position to pass over the heads of the screws E E. The notch F on the bezel is of such depth as to serve not only as an index, but also as a means of turning the bezel. Of course the latter function of the notch is not essential, since the bezel may, if desired, be provided with aknob or pin for rotating it; but I prefer to use the' notch for this purpose as simpler, and also as being wholly out of the way.

The operation of the device above described is evident. The bezel being so set with reference to the dial that the proper character on the-bezel corresponds with any given day of the month on the dial, each succeeding day of the month on the dial will register with the corresponding week day character on the bezel, and thc index D will show from day to day not only the day of the month, but also the day of the week. Since there are thirtyone numbers on the dial, and since this number does not correspond to any exact number of weeks, it is evident that the bezel must be adjusted from time to time with reference to the dial, and the frequency with which such adjustment will be necessary depends on the number of sets of week-day characters on the bezel. Thus if a single set of seven characters be marked on the bezel the adjustment must be made weekly, and if two, three, or four such sets be marked on the bezel the interval is correspondingly lengthcned. It is of course `preferable to mark twenty-eight characters on the bezel, thus making the interval from one adjustment to the next four weeks; but this is evidently notessential.

In Figs. l, 2 the bezel is represented as marked with four sets of week-day characters, and it will be noticed that the screws E E and the notches in the liange Bl are so placed that the week-day characters on the bezel may always be properly adjusted with reference to the dial without bringing the notches into the position in which they can pass over the heads of the screws. In other words, the use of the four sets of characters cuts down the necessary angle of adjustment to considerably less than ninety degrees, and so prevents the possibility of accidental disengagement of the bezel from the case during the adjustment of the bezel with reference to the dial.

Figs. 3, 4 illustrate a modification of my invention, the week day characters being marked .on a ring, B, lying just within the inner bevel, B', of the bezel, and provided with an adjusting-pin, I), projecting outward through a suitable slot in the bezel. In this case the -bezel is preferably stationary with reference to the dial, and the week-day characters are adjusted by turning the ring B.

Fig. 6 shows a bezel having the week-day conical ring B illustrated in Figs. 4, 5. All

these forms, together with others that might be enumerated, are, however, but equivalents for the form shown in Figs. 1, 2, which I consider the most practical and desirable which can be devised, each of said forms being in substance a ring marked with characters indicating the days of the week, and susceptible of angular adjustment with reference to the dial.

The drawings illustrate the application of my invention to a watch or pocket time-piece; but it is evident that it is equally applicable to a clock, and that its application to and operation in connection with a clock will be the same as that illustrated and described.

Having now described my invention and explained its operation, what I claim as new, and desire to secure by Letters Patent, is-

1. The combination, in a time-piece, of a dial marked with characters indicating the days of the month, a hand or index co-operating with said dial and passing each day from one to another of said characters, and a rim or bezel adjustable with reference to the dial, and having an inner bevel next to the dial,v and an outer bevel resting on the case of the time-piece, one of said bevels being marked with a series ot' characters representing the days of the week and spaced to correspond substantially with the characters on the dial representing the days of the month, substantially as and for the purpose set forth.

2. The combination, in a time-piece, of a dial marked withl numbers representing the days of the month, a hand or index co-operating with the numbers on the dial to indicate t-he days of the month, arim or bezel susceptible of angular adjustment with reference to the dial, and having an inner bevel next to the dial, on which is marked a series of characters representing the days of the week, substantially as and for the purpose set forth.

3. The combination of the case C, the dial A, marked with numbers indicating the days of the month, the suitably-actuated hand D, the screws E E, set in the case, and the bezel B, marked with characters indicating thefdays of the week, and having the fiange B, provided with notches adapted to pass over the heads of said screws, substantially as and for the purpose set forth.
