Drum Barograph & Barometer by Short & Mason c1930 – SOLD
Short & Mason barograph recorder and barometer with mechanism overall of fine gilded brass construction. Conventional 8-day drum recorder, bearing “Pat. No. 3715.02” to top plate and serial no. “5493” to lower plate, with good quality platform escapement, captive winding key and top cover. Hinged and sprung paper clip with closing catch to top, the whole mounted on a conical base with static top mounted platform gear, serial no. “5044.” The barometer set on separate, unsigned chassis with fluted border and raised on four turned brass supporting pillars, eight capsule pressure sensing set with adjustment wheel over, having well-engineered connecting mechanism and driving delicately executed, grained white metal swinging gate arm and indicator to barometric scale. Base-mounted arrester bar with single stop pin. Silvered and engraved brass open-faced 4½” dial with conventional annotation calibrated from 28-31 inches of mercury and bearing registered design no. “428606” to bottom. Ivorene plate to cabinet base with retailer’s details. Conventional corked ink bottle with dipper, inset to cabinet base. The whole contained within its original oak case with lift-off cover of heavy bevelled five-glass construction. Frieze drawer to bottom for charts.
The instrument, having been extensively restored, the cabinet disassembled, cleaned, re–lacquered and polished, the mechanism cleaned and serviced, remains entirely original in all respects. The recording paper for an up-to-date test shows good sensitivity and function.
Instruments with this combination of barograph and aneroid barometer may be considered scarce. The majority found as untouched require re-lacquering to the case due to sun damage. This Short & Mason barograph is particularly unusual in that the mechanism is in such good original condition. It has restored very well.
