Grandfather clocks, also called longcase clocks by horologists, were invented after Dutchman Christiaan Huygens applied a pendulum as a clock-winding device in But it wasn’t until about when clockmakers mastered the workings of the pendulum for accurate timekeeping in conjunction with an anchor escapement — the mechanical device that gives a pendulum its swing.

After , most clocks were mass-produced by German and American manufacturers, effectively putting an end to the valuable custom-made grandfather clocks. English clockmakers crafted clocks with brass dials from about to Early brass-dial grandfather clocks had only one clock hand, since to clock owners, the hour of the day was more important than minutes. By , grandfather clocks with two hands began showing up in England, even though outlying villages and country regions still had clockmakers crafting clocks with only the hour hand.
From through , brass dials became more ornate and contained other features such as second hands, date hands and wheels. Grandfather clocks with moon dials appeared in clocks made from through While individual features alone are not enough to determine the age of a grandfather clock, combining different elements such as its face, hands, spandrels — the ornamentation near the clock face — and movement pillars can lock in its age. Some clockmakers also signed their work, adding their initials or signature to the clock face, which narrows the clock’s age to a specific period.

Jul 18, – Antique Swedish Mora clock dating from 17th/18th Century with Antique Swedish Mora Clock Original hand painted floral and details on a.
ETM- 3,, United States Patent Office Int. The apparatus is self-contained; includes at least two rotatable disks bearing indicia and mechanism to drive the disks at predetermined intervals to change the day and date. The apparatus may be attached to a clockwork mechanism. Background of the invention The present invention relates to mechanisms which are used in watches and clocks particularly for indicating the day of the month and operate in the manner of an automatic calendar.
Most of the known devices are limited to the use of a disk which is graduated for thirty-one days and moves ahead by one graduation for every twenty-four hours, which makes it possible to know what date of the month it is, but not the day of the week. When a month has less than thirty-one days, it is necessary to correct the date of the month at the beginning of the latter generally by causing the clock mechanism to execute several revolutions.
It is this device which is among the simplest that is most widely used in Wrist watches. Description of prior art Other known devices show, in addition to the day of the month, also the day of the week and sometimes even the month itself, but these are then considerably more complicated since it is necessary to use, in addition t0 the disk with thirty-one divisions, a disk having seven divisions corresponding to the days of the Week, which multiplies the number of movable gears and of the corresponding driving mechanisms.
Moreover, it is necessary, when a month has less than thirty-one days, to effect an adjustment relative to the respective day of the month without affecting the regulation of the day of the week and, consequently, without the possibility of causing the clock mechanism to execute several revolutions, as is the case in the devices mentioned hereinabove. As a result thereof, these necessarily complicated mechanisms are rather rare and always restricted to rather costly calendartype clocks.
In contrast thereto, it is the object of the present invention to provide for a dating mechanism which allows for the simultaneous indication of the day of the month and of the day of the week while nevertheless being very simple and, more particularly, while utilizing only a single drive mechanism and a very simple correcting means for use at the end of the month.
