The following is a translation from the book "Electrische Uurwerken" written in Dutch by W.P. Hoogeveen in 1937. "ENEM stand for Eerste (First) Nederlandsche (Dutch) Electro-Magnetische (electro-magnnetic uurwerkefabbriek (clock factory). It produced "moederklokken" (mother clocks) and daughter or slave clocks in Utrecht in the 1920s. The mother clocks were produced in hanging cases equipped with a one-second "slinger" or pendulum. "The work contains two trains. One controls the time indicators and the other is for the electrical contacts to wind the clock. This contact, located on the seconds bit shaft, closes one per minute. Both trains are pulsed by small clock springs that are wound each minute. The winding for each train is effected by a set of magnets. These are activated by the electrical contact and engage a pawl that winds the spring in an amount that is equal to the power used in driving the pendulum." The case is solid oak with mahogany and ebony inserts in the hourglass motif. The round portions of the case are "coopered" together as a barrel is, from curved pieces of oak. The clock was found in an Iowa antique shop after being rescued from a barn. When first obtained, the suspension spring was a piece of steel strapping. Where the pivot had been broken off the rural mechanic had sharpened the remaining shaft on a grindstone, awled a hole into a piece of leather and affixed it to the inside of the plate. Needless to say, the clock was not working. |
