GO TO ONLINE BROUCHURE FOR PICTURES. EXHIBITION 2005 14th - 20th August 1. TORSION PENDULUM WALL CLOCK Month going movement with deadbeat escapement, similar to the popular Anniversary clocks of the 1950’s. Dial shows minutes, hours, date and running down indicator. Designed and made by Ronnie Rafter 2. 8-DAY BRACKET FUSSEE TIMEPIECE Fussee movement with Brocot escapement. An unusual feature of this clock is the tree depicted in the arch which changes colour with the seasons. It also shows the current position of the sun in the sky, indicating midsummer, midwinter and the solstices. The movement also features a breakaway crutch which protects the escapement if the clock is inadvertently moved . Designed and made by Ronnie Rafter 3. “ST. GILES” SKELETON TIMEPIECE Month going Fussee with twin barrels. The up/down indication is shown on the semi-circular dial below the main dial. Designed and made by Ronnie Rafter 4. 8-DAY REGULATOR A standard Regulator with Harrison maintaining power and Graham escapement. The pendulum jar contains 10 kilos of mercury to compensate for the changes in temperature. Made by Ronnie Rafter 5. MILLENNIUM CLOCK 8-Day weight driven with Brocot Escapement. Being involved in the time business the Millennium could not go by without recognition. This clock is the result. The clock shows many aspects of time – the outer dial showing the minutes, the inner dial showing Solar time, the months and the equation of time. Six small dials indicate the following : 1. The seconds 2. The phases and age of the Moon. 3. G.M.T., the age of the Moon and state of the tide at Leith. 4. The hours. 5. The current position of the Stars. 6. The date. Designed and made by Ronnie Rafter. 6. ELEGANT SKELETON CLOCK English Design around the 1840 Period. This clock has a recoil escapement and a Fussee driven movement. It also incorporates Harrison’s maintaining power which keeps the clock going during winding. Made by Archie McQuater 7. LARGE WHEEL SKELETON CLOCK A French Design of around the 1820 Period. This clock has a large recoil escapement driven by a going barrel with the pendulum suspended on a thread. The large barrel wheel has 290 teeth. Made by Archie McQuater 8. HERBERT SCOTT ELECTRIC CLOCK A Herbert Scott design of around 1906. The pendulum driven escape wheel moves one tooth per second and runs on a 3 volt battery for one year. Herbert Scott was in fact the brother of Alfred Angus Scott who famously founded the Scott Motorcycle Company in 1908. Made by Archie McQuater 9. LARGE ELECTRIC BALANCE WHEEL CLOCK A uniquely designed battery clock . As the balance wheel passes over the electro magnet it receives an impulse from the coil. The single coil uses a 3V battery giving a duration of one year. The movement incorporates Harrison’s anti friction bearing wheels and a Bulle Clock style gear train. Designed and made by Archie McQuater 10. “LYRE” SKELETON CLOCK This clock is based on a design by W.E. Smith of America and features a Le Roy spring pallet escapement. The clock has maintaining power and epiocyclic motion work. Designed and made by Iain Maconochie 11. SKELETON CLOCK This clock, which is driven by a Fussee movement, has Harrison’s Grass Hopper escapement. It is based on a design by W.E. Smith. Made by Iain Maconochie 12. WALL MOUNTED REGULATOR An eight-day wall mounted, weight driven Regulator with Invar Pendulum, compensated pendulum Bob, maintaining power and a weight tray for fine adjustment. A four-legged gravity escapement impulses the pendulum. The Clock shows seconds, minutes, hours, the equation of time, a rotating Moon showing the phases of the Moon, and has a weight driven perpetual calendar showing the date (self correcting for long and short months and Leap Years) and the day of the week. Designed and made by Iain Maconochie 13. “TAIL WAGGING THE DOG” This 8-Day Pendulum Timepiece has no pendulum . The movement itself acts as its own pendulum, the impulse is applied via the steel pin mounted on the brass pillar. Designed and made by Ronnie Rafter 14. MULTI DIAL BRACKET CLOCK 8-Day movement with Brocot escapement and breakaway crutch. The large chapter ring shows the minutes. Within that are five smaller chapter rings: 1. The age of the Moon. 2. 24-hour dial. 3. The present state of the tide at Leith. 4. Day of the week. 5. Date of the month. The phases of the Moon are shown in the arch above the large chapter ring. Designed and made by Archie McQuater 15. WALL TIMEPIECE This clock is weight driven, has Harrison maintaining power and a visible escapement. A slightly unusual arrangement is used in the pendulum. The crutch leans on the pendulum and is not attached in any way. This does reduce the impulse but it should improve timekeeping because for 50% of the time the pendulum follows the crutch instead of being pushed by it. Designed and made by Ronnie Rafter. 16. FLAT - BED FUSSEE STRIKE 8-Day Fussee movement with count wheel striking mechanism. The impulse is transferred to the pendulum via the impulse pin which is triangular and made of glass to reduce friction. It is in fact made from an old thermometer. Designed and made by Ronnie Rafter 17. BULKHEAD TIDAL CLOCK Due to the combined effects of the Sun and Moon , the times of the high tides can vary by up to 43 minutes. This unique tidal clock predicts the precise time of high tide at a chosen location. The actual time before and after high tide is indicated by the large hand. The left-hand smaller dial indicates G.M.T. , while the other small dial indicates the age of the Moon, which is relevant to the time of high tide. The mechanism can be adjusted internally to suit any location. Designed and made by Archie McQuater 18. ORRERY This hand driven Orrery shows the position of the Sun, Mercury, Venus and the Earth with its satellite the Moon at the date indicated on the 365 day calendar ring. The Sun rotates on its inclined axis and Mercury and Venus rotate in circular orbits round the Sun in accordance with the latest available data. The Earth and Moon rotate in an elliptical orbit round the Sun and the Moon rotates synchronously as it orbits the Earth. The Moon’s path as it orbits the Earth rises and falls as it orbits and the path rotates round the Earth in approximately 18.6 years. The Earth rotates daily on its axis and the axis rotates yearly to give the seasons. Turning the handle once progresses the whole mechanism one day. Designed and made by Iain Maconochie 19. SIDEREAL CLOCK Looking through the oval area between North and South reveals the current position of the stars. The same view can be seen again on the dates and time indicated around the outside of the ring. GMT is indicated around the outside of the dial by the “sunburst” hand. The clock is designed for use at latitude 51.5 degrees N. Designed and made by Ronnie Rafter 20. 8-DAY SWINGING BALL CLOCK A continuously rotating 1” diameter ball is driven by a gear train from underneath, via a steel wire 0.008 dia. giving time keeping beyond expectations i.e. 1 - 1.5 minutes / week. Original design possibly French 1850 and again by an American company, around 1900, who produced a 30-hour novelty clock which kept appalling time. Designed and made by Archie McQuater. 21. AFRICAN WALNUT BRACKET CLOCK 14-Day striking movement with countwheel mechanism and jewelled Brocot escapement. It has a silent mechanism and external regulator, both operated by the small hands above the main dial. Designed and made by Archie McQuater THE CASES FOR EXHIBIT NOS. 4, 5 & 21 WERE MADE BY PETER CUTHBERTSON OF “ALL TIMBER CRAFTS”. SOME OF THE SPECIALIST ENGRAVING WAS DONE BY PETER FOX OF NORFOLK.
