Barograph by Short & Mason. In an oak 5-glass case, circa 1930. A superb quality and attractive barograph by this good maker. The 8-day duration, drum timepiece clock movement with its original jewelled, lever, platform escapement. Contained in a revolving 3 3/4" diameter brass chart drum. This is mounted upon the top base tier as is barometric cradle with a 12-tiered stack. The nib on the end of the floating arm is refilled when the chart is changed weekly from its front-mounted glass ink bottle and dipper. The timepiece movement is wound weekly by removing the top cover to expose the fixed winding key and the platform escapement hatch which can be slid open for regulating the timekeeping. There is also a chart-change holding bar to lift the nib away from the drum when necessary and for transit. The oak 5-glass cover simply fits over the top tier of the well-figured moulded base and is lifted off to operate the device. All of the glass panels are bevelled and the base contains a double-depth, chart drawer. Short & Mason Limited was founded in 1875 by Thomas Short and James Mason. They were based in Hatton Garden, London and continued until 1969. *Barographs are not only attractive but also provide a good deal of fun when operated. They also provide a lasting record of local weather conditions
