Description

SOLD     –      RE-LISTED AS THE ITEM WAS NOT PAID FOR.

 

An oak cased anenometer dial by ‘J.J. Hicks, Maker, London’ measuring 11″ x 11″ with a glass panel to the hinged door, the centre glass with a brass lug and pointer and dial hand fixed to a sleeve in the centre of the brass dial.

There are two terminals to the top of the case with wires to the inside, which run down the inside and connect to two electro-magnetic? coils and continue to a toothed-wheel with a lever and claw. Turning the brass sleeve at the centre of the dial slightly anti-clockwise connects a small spring loaded plate to the coils. The dial, no doubt, works with wires from the external terminals being joined to a set of Robinson’s cups, which is fixed on the roof of a building, or other elevated position. Earlier versions required two batteries and it is unsure if this example would have required the same or whether it was powered from a mains supply. I have not been able to locate a similar item.

Such items would be placed in a library, dining room or other convenient place for observation.

Abrasion mark to the dial at ’80’.
