H. AEBERHARDT wA'rcH MOVEMENT Filed March 17", 1937 2 Sheets-Sheet 2 \NVENTOR Hans AEBERHARM By M rromvsvs Patented Jan. 9, 1940 UNITED STATES PATENT OFFICE Application March 17, 1937, Serial No. 131,527
In Switzerland March 21, 1936 4 Claims.
The present invention relates to a movement for calendar watches having a continuously moved date gear wheel. According to themvention the minute Work is operated by gear 5 wheels supported by a pin which is mounted within a hollow shaft driven by the barrel. These gear wheels include a pinion meshing with a gear Wheel, which on its other side meshes with a further gear wheel provided with a pinion imparting to the date gear wheel a continuous rotation.
In ordinary watches the minute work is always mounted on the staff of the center gear wheel, except in the system, Roskopf. Also according to the present invention the minute work is not directly operatively connected to the center gear wheel, but to an intermediate gear wheel which transmits the movement from the barrel to the center wheel. This intermediate gear wheel ensures a several days movement and besides a rapid and exact setting of hands, time and date.
The annexed drawings show two embodiments of the object of the invention, but only those parts which are needed for an understanding.
Figs. 1 and 1a, are plan and section. of a first embodiment where the calendar wheels are eccentrically arranged, the section being taken on the broken line Ia-Ia.
Figs. 2 and 2a are plan and section of a concentric arrangement of the date wheel, the section being taken on the broken line IIaIIa in Fig. 2.
Fig. 3 shows a dial where the weekdays hand is arranged eccentrically and the month days 35 hand centrically.
Fig. 4 shows an arrangement of hands corresponding entirely to the arrangement of Fig. 1.
According to Figs. 1, 1a, 2, 2a driving pinion l meshes with a barrel (not shown). Within the 40 sleeve of this pinion I a staff is held, which will be taken along by said pinion and which by means of gear wheels 2, 3 and 4 fixed thereto moves the whole minute and calendar work. The gear wheel 4 meshes with the hour gear wheel I and pinion 2 meshes with the idler gear l2 pivoted to a screw II. A cannon l is. carried by the hour gear wheel 1'. Gear 3 itself drives the cannon pinion 6 pivoted to a staff arranged and fastened at the center of the movement. The idler gear I 2, serving also for the time setting, moves the calendar driving gear wheel I3 to which is rigidly attached a large pinionv l4 and a small pinion l5. Pinion [4 drives the weekdays gear wheel 9 and the sleeve 9. Pinion l5 meshes with the date gear wheel 8, 8' (monthly days 1-31). The date gear wheel 8 could also be located at the center of the movement, as shown in Fig. 2. If the staff [6 of the gear wheels 13, I4, l5 as shown in Fig. l, is at an equal distance from the stafis 5 and H], the date gear wheel 8, 8 could be placed at will either in the position as shown in Fig. 1, or in the central position as shown in Fig. 2. If staff; it is unequally distant from the staffs 5 and H) a change of position of the date gear wheel into the center is not possible.
The staff ID of the date gear wheel may be located also at another place than at the one shown.
The time setting by means of idler gear wheel i2 is made possible, due to the fact that idler gear wheel 12 meshes with pinion 2, and pinion 4 which is fast to this pinion 2 meshes with the hour gear wheel.
In the drawings the place of the seconds gear wheel staff is marked with ll, the dial with i8 and the plates with IS.
In the Figures 3 and 4 the weekdays hand is marked with 20 and the dates hand with 2!.
This latter hand is attached easily and adjust- L ably by hand to the cannon portion 8 of the date gear Wheel 8. As shown in the drawings, the required resiliency of hand 2! has been obtained by a slot in the hand itself. Such a slot could also be provided for the hand 23.
Both Figs. 3 and 4 show dials for auto car or standard clocks and have the circular movements attached to their backside.
In Fig. 3 the weekdays hand 20 is eccentrically arranged, while the months date hand 21 is arranged on the sleeve 8 of gear wheel 8' con.- centric with center staff 5, the graduations being marked on the square framing. The respective movement is like that shown in Fig. 2.
In Fig. 4 the weekdays hand and the months date hand are arranged eccentrically, which arrangement corresponds with the arrangement in Fig. 1.
In the working examples described the winding mechanism and the time and date setting mechanisms could be provided with a crown or with a key. The time setting with a crown by means of the idler gear wheel IE or by means of a key engaged directly on a square headed of the staff 0 permits a quicker setting of the hands to time and date. By the fact that the minute work is operated by a transmission wheel meshing directly with the barrel the movement may be kept running for several days.
As regards the arrangement of the weekdays dial inside of the month days dial, as shown, this arrangement could also be the reverse.
