about 100 years old, is engraved on the silver compass dial

ANTIQUE
PRE - HEDLEY MINING DIAL by HEWITSON
NEWCASTLE. A fine and rare mahogany antique mining dial, engraved
in script on the silver compass dial Hewitson,
Newcastle upon Tyne. John Hewitson worked as a mathematician and
Instrument maker in Newcastle on Tyne from 1844 to 1856, making instruments for
the marine trade and the local mining industry. The compass
dial and sight arms are set into the original mahogany base, with a matching
“lid” completing the instrument. The horizontal silver
compass is scaled 0 – 360 degrees and has four 0 – 90 degree scales on the
inside with cardinal points. The mahogany “lid” is carved on the inside to sit on top of the
instrument forming a protective cover and when closed
activates the needle clamp. 2 brass latches to the sides secure it and beneath
the instrument there is a screw-threaded boss for a tripod mounting. This
transitional dial was made before the Headley Dial was patented and shows the
ingenuity of local instrument makers to manufacture a practical instrument to
suit the local needs. There are
clear signs of use shown on the mahogany, including a deep burn on the underside
of the “lid”, perhaps where many candles have been stood to illuminate the
dial. It is a very rare instrument (I hesitate to say “unique” as someone
will no doubt find a similar one somewhere to prove me wrong) the like of which
I have not seen in any collection. -£950
A
fine antique mining dial, early 19th
century, (circa 1830) engraved in script on the silver compass dial
W&S Jones, Holborn, in its original fitted mahogany case. The sights
fold over the original brass lid, and the stand attachment detaches from the
instrument to fit into the case. The horizontal silver compass
has four 0 – 90 degree scales and cardinal points, and the outside ring is
scaled 0 – 360 degrees with the vernier to the north. The instrument has a bubble
level located on one arm, a thumbwheel underneath with
which to turn the dial horizontally, a locating pin to set the North/South axis
in line with the dial axis and a sliding needle clamp. The instrument comes with
its original brass cover which is engraved with scales
and marked “links”, and original stand attachment,
which has an unusual clamp allowing the dial to be tripod mounted either vertically
or horizontally. The whole instrument and its case are
in very good condition. - £750

pinion focusing and internal focusing cross hairs, and ray shade with dust
shield to the objective. The lengthwise bubble level is eight and a half inches
long, and the cross bubble is two inch long. Both are in good working order.
Below the telescope is mounted a four inch compass with needle clamp and scale magnifier,

catch is provided in the upper case to cover the re-set wheel. The instrument
has a two position shutter for speeds above and below 30 feet per second and

Very few of this type of instrument were made as, shortly after the design was
introduced, the adverse effects of aluminum in a coal mining atmosphere were
discovered, making this a very rare anemometer. - £185
