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.

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.

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, [25] [26] [27] 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, [31] 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.

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.
