Short 10″ pendulum and verge escapement. Because of the short pendulum it could stand on a table, but the timekeeping was poor. Another Lantern clock, C , with the “new” long pendulum and anchor escapement this clock had to be hung on the wall to run. Often known as “hoop and spike” clocks because of the iron hoop to hang the clock from, and the spikes at the bottom to dig in the wall and keep the clock steady. From now on the timekeeping of clocks improved by a huge amount using the longer pendulum and “anchor” escapement. Around the same period, with a slightly larger dial and a wooden hood to keep the dust out of the clock movement. Still the same lantern clock movement inside, but without the expensive brass body. It would not be long before the weights and pendulum were enclosed altogether to stop the pendulum being knocked accidentally when walking past the clock. The first fully-enclosed clock known dates to , the one pictured here was made by Edward East in London, dated
How to Identify Antique Clocks
Clock Lore Clock Lore from Der Uhrmacher American clock movements have undergone many innovations over these passed generations. These innovations took the form of unusual repairs by local tinkers. It’s not uncommon to examine an antique American clock movement and find a piece of bailing wire plugged into a worn pivot hole. Glue took the place of solder when piecing together broken levers and solder was used to fuse anything that didn’t look right to the beholder.
An old timer brought in his American clock boasting that it was running for 25 years without missing a tick. He never had it cleaned or oiled and couldn’t understand why it stopped.
Clock hands and dial features: minute hands were introduced to longcase clocks c. — matching minute and hour hands were introduced c. ; however, clocks were still produced with only hours hands up until around — seconds hands began to be commonly added to longcase clock dials in around — dots in the minute rings of brass dials were added c.
Renaissance Turret Clock, German, circa Spring driven Matthew Norman carriage clock with winding key Clockmakers developed their art in various ways. Building smaller clocks was a technical challenge, as was improving accuracy and reliability. Clocks could be impressive showpieces to demonstrate skilled craftsmanship, or less expensive, mass-produced items for domestic use.
The escapement in particular was an important factor affecting the clock’s accuracy, so many different mechanisms were tried. Spring-driven clocks appeared during the 15th century,    although they are often erroneously credited to Nuremberg watchmaker Peter Henlein or Henle, or Hele around This resulted in the invention of the stackfreed and the fusee in the 15th century, and many other innovations, down to the invention of the modern going barrel in Early clock dials did not indicate minutes and seconds.
A clock with a dial indicating minutes was illustrated in a manuscript by Paulus Almanus,  and some 15th-century clocks in Germany indicated minutes and seconds. Some of the more basic table clocks have only one time-keeping hand, with the dial between the hour markers being divided into four equal parts making the clocks readable to the nearest 15 minutes. Other clocks were exhibitions of craftsmanship and skill, incorporating astronomical indicators and musical movements.
The next development in accuracy occurred after with the invention of the pendulum clock. Galileo had the idea to use a swinging bob to regulate the motion of a time-telling device earlier in the 17th century. Christiaan Huygens , however, is usually credited as the inventor.
Providing you are reasonably competent from a mechanical skills perspecitve cleaning a clock is well within your capability. There are a few tricks but basicly its dissasembly, cleaning and then re-assembly in reverse order. The following slides show an 8 day movement.

Grandfather Clocks Grandfather clocks evolved with the development of the pendulum clock in the 17th century. Innovative clockmakers lengthened pendulums in order to create a more reliable timekeeping device, and a case was needed to protect the pendulum and weights for domestic clocks. This inconvenience was solved by creating the longcase style of clock, more commonly known as the grandfather clock.
movements which were available even in the late 18th century. The clock that I will use to explain the process is a mahogany cased (veneered), brass dial, musical longcase clock. It has a 12in dial and the clock properly dating a clock, authenticity or originality is often resolved in the process.
In the company name was changed to Waltham Clock Company. Additionally, Waltham Clock Company produced outstanding marine and engine room clocks. Marine clock production began in approximately In addition to Star Brass Manufacturing Co. Waltham marine movements, along with those of the Eastman Clock Company and Chelsea Clock Company appear almost identical in design and utilized escapement material apparently from the same supplier, American Waltham Watch Company. Chelsea was the winner in marine clock production by the early s, having absorbed the remnants of Eastman Clock Company and out produced Waltham by a tremendous margin.
The early type Waltham marine movements are serialized and the highest known movement serial number is Waltham did produce, in larger numbers, marine movements of another style, movement 12, with the platform across the movement plates into the early s, but production of the early marine type shown below was extremely limited as few examples are known today. The fact that Waltham dropped production of the early design and produced a marine clock of an entirely different design later may have been due to Walter Menns’ transfer to Chelsea and his holding patent rights to the early movement design.
Menns did transfer patent rights for the famous ship’s bell design to Charles H.

Origin[ edit ] Lateral view of a longcase clock movement without striking mechanism, mid s. The advent of the longcase clock is due to the invention of the anchor escapement mechanism by Robert Hooke around These consumed less power allowing clocks to run longer between windings, caused less friction and wear in the movement, and were more accurate. The long narrow case actually predated the anchor clock by a few decades, appearing in clocks in to allow a long drop for the powering weights.
However, once the seconds pendulum began to be used, this long weight case proved perfect to house it as well.

Schatz SCHATZ The majority of early movements have no name or logo except perhaps the two elephants , but later examples are normally clearly marked with the name and the model number. Kaiser These clocks are famous for their globe pendulums. They also sold conventional Day clocks, but bought the movements from Petersen.
Kern Kern movements almost always have a version of the KS logo, unless marked with K. S followed by the movement reference. Most have a very distinctive cut-out at the top. The factory discovered that the mainsprings in the miniature and midget models were under-powered, so you will need to measure the barrel width to identify exactly which one you have. This Japanese factory made several models, but not of the German quality.
Hauck Unmarked movements, except for a serial number, normally close to a vertical ratchet wheel cut from solid brass. Petersen Petersen movements are normally marked W. Petersen, but they were also bought by Kaiser who stamped their own name on them. Shmid-Schlenker made small antique reproductions, many with musical boxes beneath. Siegfried Haller Early examples were seldom marked but later models normally bear the Haller name.
Midget and Miniature models have the same sized plates, and there are two versions of each, making identification more difficult.
