CALENDAR-CLOCK.

SPECIFICATION formingpart of Letters Patent No. 675,763, dated June 4, 1901.

Application filed November 21, 1899- Serial No.- 7371810. (N model-l To all whom it may concern.-

Be it known that we, JOSEF WEJROSTEK, residing at Bedhost, Moravia, and OENEK WIEDEMANN, residing at Vinohrady-Prague,

Bohemia, Austria-Hungary, subjects of the Emperor of Austria-Hungary, have invented a new and usefulTimepiece, (for which we applied for a patent in Austria on the 6th day of August, 1899,) of which the following is a to specification.

Our invention relates to improvements in timepiecesgand our invention is applicable to every kind of watch or clock showing not only the hours, with their subdivisions, but

:5 also the days of the week and names of the months, the dates, and also the leap-years. We attain these objects by, the mechanism illustrated in the accompanying drawings, in which Figure 1 is a rear view of the mechanism. Fig. 2 shows the wheel adapted to make one complete revolution in four years,corresponding with leap-years, and provided with a cam. Fig. 3 indicates the wheel 3, adapted to turn oncea year aroundits'axis and havinga notchring for all the months which have less than thirty-one days and with a special notch for the leap-years. Fig. 4 shows the dial-plate.

Fig. 5 is a detail View showing the working of the catch in its different positions.

Similar numerals, refer to similar parts throughout the several views.

1 is a cam turning once in four years around its axis 2. It is integral with a wheel 20, which is provided with forty eight teeth.

Mounted on the same spindle or axis 2 is wheel 19, having onehundred and forty-four teeth. A concentric ring 3 is secured to the wheel 19. The wheel 20," with its cam 1, is

with its ring 3, turns freely on said spindle. In arranging the parts the wheel 20 is the lowest or next to the dial-plate. 2O isthe wheel 19, and the cam 1 is situated 5 inside the ring 3 on one and the same level secured to the spindle 2, while the wheel 19,.

Above wheel 7 and their signification will be explained far= ther on.

It will be noted that the notches 5 6 7 S are all of similar shape, while the notch 4 is of different shapeand extends from edge to edge of the ring. In the notch at is arranged a piece 10, mounted upon a pin 9, so as to enable it to turn around this pin. Its outer edge forms a continuation of the circular outward edge of the disk 3. Toward the cen- 6o ter of the wheel it is provided with a-pawl12 and on the other side a cavity, into which'a spring 11 is fitted, which is secured at one end to the disk 3, while it presses at its free end against the pawl 12 and presses the latter toward the center. The piece 10 cannot be turned farther than the pawl 12 will permit, toward which it is pressed by the spring 11.

It will be noted that in the relative position of the different parts as shown in Fig. 1 the pawl occupying its lowest position nearly touches the edge 18 of the cam. As soon as this part of the ring reaches the elevated edge 14c of the cam 1 the pawl 12 is lifted up.

15 is a catch on the lever 31, which is pivoted at 16, the said lever having also an arm 27. The catch 15 is continually pressed toward the ring 3 by a spring 17. At the end of the lever 31 is a spring 30, which presses 8o against one of the teeth ofthe wheel 32. This wheel 32 has thirty-one teeth and is governed by a spring 33. The lever 27 is swung once a day by the pin 28 from left to right, the pin 28 being secured to the wheel 29, which is moved by the clockwork in any usual way. The amplitude of swing of the lever 27 31 in Fig. 1 is just sufficient tomove the wheel 32 one tooth each time; The cock-wheel 29 turning once a day around its axis will move the wheel 32 one tooth farther, therefore once around its axis in thirty-one days ifthe catch reposes on the circular periphery of the disk 3. This is really the case through all the months of the year which have thirty-one days. At the end of all the other months of the year which have lessthan thirty-one days the catch 15 must fall deeper, so as to be able to turn the wheel 32 more than one tooth. In the months which have thirty days only it mo must turn on the thirtieth day of each such .the periphery of ring 3 whichis situated between the notches 4 and 5 will turn so as to pass under the catch 15. On the 28th day of February in an ordinary year the notch 4 will pass under. the catch 15,-which then falls upon the edge 18* of cam 1, which is the most advanced position shown in the diagram Fig.

5. Before the wheel 19 turns so far as to pass the notch the catch is drawn out ofv it by the pin 28, and the spring will move the wheel 32 four teeth farther. During the month of March and nearly the whole of April the part of the periphery of the ring3 will be under the catch 15, and this will fall into the notch 5; The pin 28 will draw it out and it will this time move the wheel 32 two teeth farther. The same will happen on the thirtieth day of each month which has thirty days only, so that thenotches 6, 7, and 8 will pass under the catch 15 on the thirtieth day of the consequence will be pushed a little farther from the axis 2.

Thisis calculated so that the space 4 will be partly closed just two-thirds of its width, or one three-hundred-and-sixtyfifth part of the periphery of the ring 1. Then this notch will pass under the catch 15 on the twenty-ninth day of February each leap-year. This catch 15 will fall into the part 14 of the cam, and on its way upward the spring 30 will move the wheel 32 three teeth farther.

The wheel 38 has fourteen teeth. It is turned around its axis 39 by the pin 37 of the wheel 29, and it is moved step by step by means of the spring 41. The wheel 29 being turned by the clockwork once in a day, the wheel 38 will advance one tooth daily and will turn once in two weeks around its axis. On the dial the spindle 39 carries a disk 40, which turns in fourteen days once around its own axis. Upon this disk the week-days are written twice in a radial direction, so that each day must pass under the opening 51, Fig. 4, to indicate the name of each present day. In the opposite opening 52' the names of the months will appear; This will be the case each time when the wheel 32 has turned once around its own axis. There is a pin 45 secured to wheel 32, and this pin will once each month swing the hook 43 around its axis 42,and therefore the other end of the same hook will ad- Vance the wheel 40 one tooth. This wheel is kept in place by the spring 48. It has twelve teeth, and therefore will turn on its axis 47 once each year. Spindle 47 carries a disk 49 with inscriptions of the twelve months of the year divided into equal distances and in ra- February.

dial directions, so as to make them appear beneath the opening 52 upon the dial, Fig. 4.

Upon the spindle of the wheel 32 is mounted a hand 34, Fig. 4, pointing to the days of the month. Upon the same spindle a'wheel 36 with forty teeth is mounted, gearing with a wheel 35, and it has two pins 22 and 23, which gear with the wheel 20 by the spring 21.

The spindle 24 is fitted with a wheel 24', having twenty-four teeth, which gears with the wheel 19, having one hundred and fortyfour teeth. In the drawings only a portion of the teeth of the wheels 24 and 19 are shown.

The action of the apparatus will be as follows: Wheel 29 being revolved by the clockwork once in twenty-four hours, it will swing the lever 27 31 by means of the pin 28 once each day. If at this moment the catch 15. is not engaged in any of the several notchesof the disk 3, but lies against the periphery of said disk 3, as shown in Fig. 1, the pin 28 will cause the spring 30 to move the wheel 32 one tooth farther. This will not be the case on the thirtieth day .of any month which has only-thirty days, neither at the end of At the end of February the piece 1.0 will come near the catch 15, and in the ordinary years the relative position of piece 10 and cam 1 will besuch that the elevated part 14 will be near and opposite to the pawl 12.

Only in leap-years the part 14 of this cam willbe near the pawl 12 and will elevate it and turn the piece lO around its pin 9, so as to make the notch 4 narrower and to push the end 10 one day backward in the direction of the arrow. Thus in the ordinary years the end of the part 10 will pass under andv clear the catch 15 on the twenty-eighth of February, and in a leap-year this will happen on the twenty-ninth of February. In the first instance the catch 15'will drop into the notch 4, and owing to the depth of said notch said catch will assume its deepest position, so

that when said catch is drawn out of said notch the spring 30 will cause the wheel 32 IIO toadvance a distance of four teeth, thus advancing the time four days, while in the case of a leap-year the catch 15 will fall in the notch 4 on the twenty-ninth of February and only so deep that when drawn out of it its spring 30 will advance the wheel 32 three teeth. It will be understood that the wheel 29 works continually and that therefore the catch 15 is being drawn out of the notches 4 to 8 in due time by the pin 28 of this wheel, which also moves the other parts of the mechanism con- I tinually forward, so that the week-days are pushed into their places beneath the opening 51 at the end of each day passed by the pin 37 of the wheel 38 and its disk 40, which on its face shows the names of the week-days, appearing through the opening 51. At the end of each month the pin 45 of the wheel; 32 will, by the intermediate action of the: piece 43 44, advance the wheel 46 one tooth, and the disk 49, which on its front face bears the inscriptions of the months, will therefore.

show the present month through the opening 52 of the dial. At the end of the spindle 2 and in front of the dial is a small hand turn ing with the spindle 2 once around its axis in four years. At the beginning of each year it points to the numbers 365, or once in four years to the number 366, when the leapyear begins. During the year it moves slowly toward the next quarter of its small dial, and it will be understood that it belongs to the number which it has passed on the first of Januaryofthatyear. Thissimplemechanism can be applied to every watch or clockwork, so as to give five almanac indications.
