Grandfathers' Clocks: Their Making and Their Makers in Lancaster County
GRANDFATHERS' CLOCKS: THEIR MAKING AND THEIR MAKERS IN LANCASTER COUNTY, Whilst Lancaster county is not the first or only home of the so-called "Grandfathers' Clock," yet the extent and the excellence of the clock industry in this type of clocks entitle our county to claim special distinction as one of the most noted centres of its production. I, therefore, feel the story of it specially worthy of an enduring place in our annals, and it is with pleasure •and patriotic enthusiasm that I devote the time and research necessary to do justice to the subject that so closely touches the dearest traditions of our old county's social life and surroundings. These old clocks, first bought and used by the forefathers of many of us, have stood for a century or more in hundreds of our homes, faithfully and tirelessly marking the flight of time, in annual succession, for four genera- tions of our sires from the cradle to the grave. Well do they recall to memory and imagination the joys and sorrows, the hopes and disappointments, the successes and failures, the ioves and the hates, hours of anguish, thrills of happiness and pleasure, that have gone into and went to make up the lives of the lines of humanity that have scanned their faces to know and note the minutes and the hours that have made the years of each succeeding life. There is a strong human element in the existence of all such clocks, and that human appeal to our thoughts and memories is doubly intensified when we know that we are looking upon a clock that has thus spanned the lives of our very own flesh and blood from the beginning. -
TS4002 Wireless Synchronized Analog Clock Is Designed with an Easy-To-Read Dial Face, Durable Cherry Finished Wood Frame and Tamper-Proof Glass Lens
TS4002 - Wireless Synchronized Analog Clock The TS4002 Wireless Synchronized Analog Clock is designed with an easy-to-read dial face, durable cherry finished wood frame and tamper-proof glass lens.

Ole Rømer's Pocket Watch
Poul Darnell Ole Rømer’s pocket watch Antiquarian Horology, Volume 36, No. 4 (December 2015), pp. 541–543 The AHS (Antiquarian Horological Society) is a charity and learned society formed in 1953. It exists to encourage the study of all matters relating to the art and history of time measurement, to foster and disseminate original research, and to encourage the preservation of examples of the horological and allied arts. To achieve its aims the AHS holds meetings and publishes books as well as its quarterly peer-reviewed journal Antiquarian Horology. The journal, printed to the highest standards with many colour pages, contains a variety of articles, the society’s programme, news, letters and high-quality advertising (both trade and private). A complete collection of the journals is an invaluable store of horological information, the articles covering diverse subjects including many makers from the famous to the obscure. The entire back catalogue of Antiquarian Horology, every single page published since 1953, is available on-line, fully searchable. It is accessible for AHS members only. For more information visit www.ahsoc.org Volume 36, No. 4 (December 2015) contains, apart from the regular sections Horological News, Book Reviews, AHS News, Letters to the Editor and Further Reading, the following articles and notes: NUMBER FOUR VOLUME THIRTY-SIX DECEMBER 2015 English provincial clockmaking 1695–1840.

History of Escapement Mechanisms

Escapement mechanism is a device designed to maintain a constant average speed of the escape wheel, by allowing it to rotate to the desired angle at certain impulse of time. While doing that it simultaneously support the oscillations of the pendulum or balance spring, by compensating for friction losses and air resistance. 7 century long history of escapement mechanisms, from 13th century verge mechanism up to modern-day escapements that can be found in luxury watches, will be shortly presented. Through lives of famous clockmakers and their achievements in field of making escapement mechanism will be given a new insight in science of time keeping - horology.

The Greenwich Clock at Towneley by Tony Kitto
The Greenwich Clock at Towneley by Tony Kitto Towneley Hall Art Gallery and Museums 2007 Copyright Burnley Borough Council Reading the time from the Greenwich Clock The hour hand goes round the dial once every twelve hours in the usual way but the minute and second hands take twice as long as is normal. It takes 2 hours for the minute hand to go round. At the top of the dial, starting at 12 o'clock, there are 60 divisions of one minute down to 6 o'clock and another 60 divisions back to 12 o'clock. The minutes are difficult to read because the minute hand shares the same dial as the hour hand. In comparison, it is relatively easy to read the second hand. The second hand goes round its own dial with 120 divisions, marked out in 10 second periods, once every 2 minutes. We expect a minute hand to go round the dial once an hour. Most people estimate the time from the angle of the minute hand but that is misleading when looking at this clock. 2:00 ? 2:15 ? 3:30 ? 3:45? 4:00? yes no, its 2:30 no, its 3:00 no, its 3:30 yes The Greenwich Clock at Towneley The Greenwich Clock in the entrance hall at Towneley is a reconstruction of one of a pair of clocks presented to the Royal Observatory at Greenwich by Sir Jonas Moore in 1676. It was made in 1999 by Alan Smith of Worsley, Greater Manchester, to show how the original clocks worked. -
