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. -

White Paper: the KCC Scientific Model 1900W-UNV Clock Winder for Standard Electric Clocks Ken Reindel, KCC Scientific Updated 1-26-13
White Paper: The KCC Scientific Model 1900W-UNV Clock Winder For Standard Electric Clocks Ken Reindel, KCC Scientific Updated 1-26-13 The purpose of this White Paper is to help provide some background on Standard Electric Time master clock, what a Model 1900W-UNV Clock Winder can do for it, and how the Model 1900W-UNV works. Historical Perspective. From the 1880s and beyond, inventors became interested in applying the principles of telegraphy to horology. The idea of a battery-wound master clock which would drive multiple slave clocks, effectively communicating the time signal to them, began to take shape. Additionally, it became fascinating to inventors that the “slave” clocks could be very simple with no escapements or springs, no internal batteries, and requiring little if any maintenance. Charles Warner, who founded the Standard Electric Time Company in 1884,1 was one such inventor. Very early on, Standard Electric borrowed heavily from the Self Winding Clock Company for the design of its master clock movements. Master clocks would have the characteristics described above and relied on special contacts to drive the slaves. Later on, this same concept would be extended to driving program wheels and punched tape ribbons within the clocks themselves, to provide bell timing and other electrical sequences to businesses, schools, etc. For example, many such clocks have been found in schoolhouses and were at one time responsible for ringing bells at the proper times throughout different parts of the building to send students to the next class, as well as driving classroom slave clocks. Standard Electric’s master clock movements eventually took a shape similar to that of the slave clocks: simple, elegant minute impulse ratchet designs for winding the 60, 72, or 80 beat pendulum movements. -

Remembering the First Battery-Operated Clock
© 2015 Antiquarian Horological Society. Reproduction prohibited without permission. ANTIQUARIAN HOROLOGY Remembering the first battery-operated clock Beverley F. Ronalds* Francis Ronalds invented a reliable electric clock in 1815, twenty-five years before Alexander Bain’s patent. It was powered by dry piles, a modified form of battery that has extremely long life but the disadvantage that its electrical properties vary with the weather. Ronalds had considerable success in creating regulating mechanisms for his clock to ensure accurate time-keeping in all meteorological conditions. He did not go on to commercialise his ideas, although others made and sold comparable timepieces on the Continent. This year marks the bicentenary of the with the electrically dissimilar metals. The publication of the first battery-operated dry pile was found to have an electric clock. It was rediscovered in the 1970s by potential difference or voltage across its two Charles Aked, Council member of the ends but, unlike Volta’s pile, did not exhibit Antiquarian Horology Society and first an electric current when the terminals were Chairman of the Electrical Horology Group, joined in a circuit. Its potential difference and further information has since come to was also maintained in use whereas a voltaic hand.1 pile ceased to work after a while.3 The clock was created by a prolific Two of the scientists in England who inventor named (later Sir) Francis Ronalds developed and improved the dry pile were FRS (1788–1873); he lived on the Upper Jean-André de Luc (1727–1817) and Mall in Hammersmith, London, at the time George Singer (1786–1817). -

Harrison's Wooden Clock At
Harrison’s Wooden Clock at 300 A Visit to Nostell Priory Eve Makepeace o celebrate the 300th birthday of their John Harrison T wooden clock, Nostell Priory, wanted to really put it in the spotlight. They have certainly achieved that and widened its appeal to old and young alike. For many years the clock has stood in a fairly unassuming spot within the Priory where only the eagle-eyed would realise its importance. That has all changed and the clock, one of only three surviving wooden examples by Harrison, is now at the centre of a new exhibition celebrating his skill in the place where he was born. In a custom-made display, the clock is shown without its case to highlight the beautiful wooden parts, lighting drawing the eye to the delicacy of the piece, Figure 1. Alongside the clock, visitors can also watch a specially commissioned film about Harrison and view a series of displays which celebrate his work. These include a rarely seen section of the original case, complete with calculations in Harrison’s own hand, kindly loaned by The Worshipful Company of Clockmakers. In a breakaway from the long-held assumption that National Trust properties are ‘look but don’t touch’, there are the parts of a clock displayed in a way that they can be held, examined and appreciated, Figure 2. Of particular interest to me, especially in these times of questioning ‘Conservation or Preservation?’, there is a board asking for input from visitors on their thoughts regarding the care and preservation Figure 1. of the clock.
