Dating antique longcase clocks
Quality No matter what the period of production, some clocks were always better and more costly than others. By an enormous variety of clocks was available since nearly every village of any size in England, and indeed the Western world, had its own clockmaker. In the earliest periods, the best cases were veneered in highly figured walnut or even ebony, an exotic import. Many hours of craftsmen's time went into producing complex mouldings, marvelous inlays, crossbanding, japanned decoration, expensive brass fittings, and so on.
How to Determine the Age of a Grandfather Clock
We have a working knowlage of over !!! In a Dutchman named Christian Huygens was the first person to use a pendulum, as a driving device, in clocks. This was the Start by placing the clock case in the position required. It's a good idea to have a helper during the setting up to process to prevent damage. With 8 day clocks the movement is usually attached to a seat board, place the movement board on top of the case trunk and get your helper to hold it in place.
Crutch Arm, B: Crutch Fork, C: Top Suspension Block, D: Suspension feather, E: Lower Suspension Block, F: Now the pendulum is on, there is less likelihood of the movement falling forward however it's still possible to fall forwards. E nsure the case is now level and standing firm, this is very, very important. If there is a deep skirting board you may need to position a piece of similar size wood across the back of the case to allow the case to stand level once this has been achieved and the pendulum swings freely it is recommended that the case is fixed to the wall using a existing hole through the back of the case.
The next stage is to slide on the hood. Adjust the seat board from underneath until the dial lines up perfectly in the hood frame. Remove the hood again. Hold the line about one foot down from the board and pull it tight. P lace the winding key on the square and wind very slowly, whilst keeping the line tight and watching it feed onto the barrel grooves. Without releasing the tension on the line to ensure there are no loops or kinks, turn over the pulley and place the line in the groove.
Then hang on the weight making sure to keep the line tight until the weight is in place. Repeat the same procedure with the other weight. For 30 hour clocks check that the rope or chain is correctly seated on the sprocket within the movement turn the pulley up the correct way and hang on the weight. Hand Setting. For most longcase clocks where only the hour is struck, move the minute hand ONLY in a forwards direction pausing at each hour to allow the clock to complete its strike stopping when the required time is reached.
Strike Setting. Most 8 day clocks are rack striking and so the sequence should not differ from the time. However in early clocks of 8 day or month duration the locking plate system was sometimes used which may become out of sequence at some point. To correct these, first remove the hood and look at the left hand side of the movement. On the very back plate or in front or behind the largest wheel, attached to the barrel, there will be a wheel without teeth but with notches cut into its circumference at uneven intervals.
Resting on this locking plate circumference will be a lever, which must be raised and released to activate the strike. Continue to release the strike until the number struck coincides with the time. For 30 hour clocks most are locking plate striking and will probably need correcting fairly frequently if allowed to run down. The locking plate should be easily found. Use the same method of correction as described above with 8 day clocks.
Date Setting. Three types of date are in common use. The centre date hand, the hand on a subsidiary dial or the date showing through an aperture. Centre date hands can be moved backwards or forwards manually, except when the clock itself is trying to turn the date over a period of a few hours at night, if the clock is set in the correct 12 hour sequence. Hands on subsidiary dials sometimes change every 24 hours or quite often every 12 hours of half a division. The hand can be moved manually but if any resistance is felt at all it should be left to another time as the clock may be trying to turn itself.
Two types of aperture dates are used. For those showing in a segmental aperture, the wheel usually turns through half a division every 12 hours and so at certain times it may not be moveable. The easiest way is to gently push round the dial through the aperture in the direction of the figures, counting up until the correct date is reached. Those dates showing a single figure in a square aperture are turned by revolving the date ring from the back of the dial after removing the hood.
They can be moved backwards or forwards except when clock is driving the date itself. The only way of regulating for most longcase clocks is by the pendulum itself. The nut at the bottom of the bob is screwed up to the right clockwise to make it go fast and left anti clockwise to go slow. It is advisable to hold the bob whilst doing this to prevent the rod being twisted and damaging the suspension feather. Latest Tweets.

Dating Antique Clocks
Ok so youve got a grandfather clock and you want to know roughly how old it is. Here are some basic paramaters to allow you to see the date ranges of the various features so you can get an idea without doing a whole load of reasearch on makers and suchlike. The first Grandfathers produced in London because Christian Huegens invented the pedulum clock. Before this clocks were…well they sucked really as timekeepers. If a clock lost 5 minutes a day it was doing well but with the pendulum clock you could get it down to 5 minutes a week. The pendulum clock was therefore a very useful thing but of course you needed a long case to cover the long pendulum the longer the more accurate and the Grandfather or Longcase clock was born. The square dial persisted until by which time it was going out of fashion ans was completely replaced by the arched dial with exceptions of course by All faces were brass up until when the painted dial came along. Less expensive to produce and engineer it became the favourite for the majority of clocks produced outside the cities. In clocks were tall and thin with small faces.
The origins of the longcase clock are somewhat confused but it seems that they originated from the lantern clock. This type of clock had evolved from having a balance wheel escapement to the anchor escapement with a long pendulum and weights hanging underneath.
Antique Longcase Clocks
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. If you own a longcase clock, determining its age can tell you how much it is worth. 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.

However, a signature may refer to someone other than the clockmaker. The actual movement may have been made by someone else. Until the 19th century clock cases were almost always made separately from the movement and are rarely signed. It provided a safe alternative to the hazardous use of mercury in gilding metals, which was banned c. They are metal rods specially tuned to produce a sequence of chime notes when struck by the movement's chime hammers.

How To Date Your Grandfather Clock If your grandfather clock has a brass dial, it was probably made in the period between and The early brass dial clocks only had one hand, because the average person had no need of knowing the time to the nearest minute, and with a bit of practise you can tell the time to the nearest five minutes on one of these early and rare clocks. By the vast majority of grandfather clocks had two hands, for the hours and minutes. One-handed clocks continued to be made in country areas for a while after From around all these figures are approximate all the way through this article the brass dial clock was made all over England in ever-increasing numbers, and the dials became more ornate as time went on, especially on the eight-day clocks. Painted dial clocks appeared about to , and after this the brass dial clock ceased to be made, again with just a few exceptions in rural areas, especially the far southern counties of England. The new painted dial was cheaper and easier to produce and easier to read by the poor light available at night, so the brass dial was dropped from production over a very brief period, for our purposes it is fair to say that no brass dial clock was made in the big clock making centres after
