Example of a double-width master clock case produced in the 1930's for anAR3 system. Having the program movement in a separate compartment prevented the pendulum from possibly being disturbedwhen changing a ribbon. Early 1920's master clock by Pacific Electric Clock Co.Early 1920's master clock by Pacific Electric Clock Co., San Francisco(later Berkeley), California. This company was acquired by Standard in 1923; note similarity of case designs.Features mercurial pendulum, 2 pilot clocks, milliammeter and single-ribbon 4-circuit program.
Detail of a clock somewhat different from that pictured above. Pilot clock design lacksthe usual protective glass. Program movement mechanically driven directly from master movement.
Knotty Pine Master ClockLumber for cases was carefully chosen, with routine rejection of pieces containing knots.But here is a significant exception: at least one customer ordered their clock in knotty pine! Note: decorativecorbels were omitted from later cases; this one is perched on a separate shelf which we hope doesn't have to supportthe weight of the clock.

Pendulum synchronizer of master clock at Rockville Public Library. Presumablyonce connected to a more accurate (mercurial pendulum) and frequently checked clock at the store of John C.Whittlesey, Jeweler, 4 Park Place, Rockville, who in 1902 advertised an 'Electric Time System'. Theelectromagnet would normally receive a brief impulse every few seconds from the jeweler's regulator to maintainsynchrony between both clocks. Tiny weights could be added to or removed from the pendulum of the governingclock without stopping it, gradually correcting the slightest deviation from observatory time as received bytelegraph. Closeup of plaque beneath mall clock. To make this project a success, your help is needed.If you can provide a good picture of a special clock, it could well proveto be something that others would enjoy seeing here. Owners of clocks willreceive credit unless they wish to remain anonymous.
In return, or as a publicservice, we can provide in over 90% of cases, copies of original factory publicationspertaining to a specific clock. These include master clock instructions, technicalbulletins and wiring diagrams.Inquiries concerning available materials may be E-mailedtoThanks for looking!
