PATENT OFFICE

CLASS 83: Clocks.

The novelty of the present invention compared to the existing calendar clocks (e.g. P. R. No. 15406) consists of:

1. that the mechanism of the calendar work is closely connected with the clockwork stands and is not in the shell of the lid, but on the housing itself;

2. That the designation of the days of the week (Monday, Tuesday, etc.) is not on a movable one or rotatable rings, but on an edge firmly connected to the housing, the data from 1 to 31 against it and the Month names are arranged on a movable disc that can be set from the outside, and that the disc with the month names on its own, as well as in connection with the Data disk can be moved;

3. that the movable disks not only at the beginning of a month, but also at any later times can be set quickly and correctly without furthermore an adjustment of the pointer becomes necessary.

These three essential differences characterize the present invention.

The attached drawing shows:

Fig. Ι the top view of the disk ά with the dates 1 to 31 and the fixed edge g with the days of the week,

2 shows the upper view of the disk b lying under the disk α,

Fig. 3 shows the section through the calendar mecha ^ · nism,

Figure 4 shows the mechanism for moving the discs.

As the drawing, FIGS. 1 and 2, shows, the days of the week are fixed and immovable on the edge g.

The disc b, which contains the twelve names of the months with the number of days and on which the pawl c with the spring d is arranged, is movably attached to the case of the watch, as it were as the cover plate of the watch case. A ring gear f is arranged on the lower side of this disk b.

Above the disk b , the also movable disk α with the data 1 to 31, the section e and the toothed edge / is arranged in such a way that as soon as the disk b is moved to the right, the pawl c engages in the toothed edge / the disk α and so α is carried along by b , while the pawl c is released when the button w is turned to the left , α rubs against g at χ , thereby stopping and the disc b goes to the left alone until the desired month with the number of days appears under the opening e .

h, Fig. 1 and 3, is the calendar pointer, which sits on the shaft going through the openings i and k and is thus moved by the clockwork evenly from day to day by one field of the day.

In order to be able to bring about the movement of the disks α and b from the outside, the movement mechanism shown in FIG. 4 is arranged, which is moved to the right or left by means of a remontoir mechanism with double pushers by turning the button w.

The axis r going through the remontract works is angular (square); at the bottom of this

On the axis r , the downward-toothed wheel m is arranged in such a way that it engages the pointer wheel η as soon as the pusher s is pressed down, whereupon the hands of the clock can be set by turning the button w.

With m firmly connected, but toothed upwards, the wheel / is arranged; Above the same rests loosely on the axis r the wheel q, which always engages in the tooth edge / the disk b.

If the push-button ο is pressed down, p goes up and engages with its teeth in q, whereby the disc b can be set by turning the button w.

Should z. B. a new month can be set, then ο is pressed down, whereby / in q respectively. b engages; w is turned to the right and thereby the disk b and with it at the same time the disk α connected to b by the pawl c advanced until the date to be set (digit of the day) is exactly under the name of the day of the week that corresponds to that digit; Once this has happened, the pawl c is triggered by turning the button w to the left and the disc b goes alone, since the disc α za. g at χ rubs and is held here, to the left until the required month name with the number of its days appears under the opening e and the latch c engages in / again.

Claims (3)

Patent claims: The following arrangements for clocks with a calendar: 1. The movable disk b for the month names with the pawl c, the spring d and the ring gear /. 2. The movable disk α for the digits of the days with the toothed edge /, through which the connection of the disk α with b is effected by means of the pawl c. 3. The combination of the disk a , which is rotatable on the housing under the edge g , with the likewise rotatable disk b, which can be set on its own or with α at the same time by the toothed ring / externally. 1 sheet of drawings.
