Excerpt from Time-Keeping in London: Reprinted for Distribution by the Observatory of Washington University, St. Louis, From the Popular Science Monthly, December, 1882, January, 1883
It is proposed in this paper to describe some special features of the instruments by which time is kept at the Royal Observatory, Greenwich, the means for correcting them, and the methods and instruments by which time-signals are distributed from the observatory to London and elsewhere.
The primary standard time-keeper of England is a sidereal clock kept in the basement of the Royal Observatory, Greenwich. This clock is of the best construction, and is, moreover, provided with the most approved apparatus for compensation and correction.
Experience has shown that the best results are obtained when the connection between the driving-weight and the pendulum of a clock is as slight as possible. This has been accomplished in the Greenwich clock by the use of an elegant escapement, the details of which are shown in Fig. 1, representing a back view of the clock-train. The crutch-axis, supported by the arm (c) and the back plate (b) of the clock-train, carries an arm (e), attached at f to the left-hand pallet arm. The pallets are carried by the crutch-rod (d). At g is attached a detent projecting toward the left and ending in a light curved spring. Near the top of the escape-wheel this detent carries a jeweled pin which locks the wheel. The action is as follows: When the pendulum swings toward the left, the arm (e) lifts the delicate spring at the end of the detent, the wheel is released and drops forward so that a tooth presses against the face of the pallet and gives an impulse to the pendulum; the spring at the end of the detent immediately locks the wheel again, and the pendulum swings on freely to the left.
