EDINBURGH

THIS BAROMETER / ALTIMETER IS EXTREMELY UNUSUAL AND RARE AS THE DIAL IS INSCRIBED WITH ALL THE WEATHER POSSIBILITIES AS FAR AS

HURRICANE

Elizabeth Lennie took over from her husband, James Lennie, when he died in 1857, and continued to trade until 1901.

The barometer is calibrated from 28" to 31" mercury, and the outer, altitude scale is calibrated from zero to 3,000 feet. The silvered dial is in very good condition with no wear to the black markings. The original fire gilt is still over 90% intact. The original Morocco leather transit case is in very good condition, with the original silk and velvet interior still intact.

Instrument diameter 46mm

THIS IS IN EXCELLENT WORKING CONDITION, AND VERY GOOD COSMETIC CONDITION - A VERY RARE EXAMPLE OF SUCH AN INSTRUMENT CALIBRATED TO "HURRICANE"

CASARTELLI
BRASS OPEN DIAL
WALL BAROMETER

LOVELY CONDITION
VERY ACCURATE

Gloria Clifton's Directory of British Scientific Instrument Makers 1550 - 1851 shows that, of the three Casartelli businesses registered in Liverpool, the only one to use the simple signature "CASARTELLI" was the partnership "Anthony & Joseph Casartelli", who traded between 1845 and 1849.

The brass case still retains most of its original lacquer. The original glass is free of chips, cracks and scratches. The steel pointer and principal screws on view through the open centre of the dial still retain all their original blueing. The entire mechanism is easily viewed through the large aperture in the centre of the dial. This is a very old and very beautiful barometer.

Dial calibrations as per photographs.

Larger photos will show the beauty of the internal mechanism much better, so if you are interested in this item please EMAIL me and request larger images.

VERY RARE
JAMES PARKES & SON
ANTIQUE - circa 1850
POCKET BAROMETER - THERMOMETER

This instrument bears the famous "eyeball" trademark of Jas. Parkes & Son, who traded from 1845 until 1862 from St. Mary's Row, Birmingham, England.

James Parkes & Son were noted for only selling items they had manufactured themselves. They were a very small manufacturer, and the number of items still extant bearing their signature is low.

This pocket barometer / thermometer is in perfect working condition. It tracks a certified master barometer with acceptable accuracy, and the mercury thermometer maintains accurate readings.

The silvered dial is clean, the blued steel pointer has no rust, and the mercury in the original thermometer has no gaps.

As you can see in the following photographs the dial is mounted on a brass skirt that sits over the movement within the case. This shows that this is one of the earliest pocket aneroid barometers, as by the 1860s the dial had become simply a flat disc that sat over the movement.

The original bevelled crystal is free of cracks, scratches or chips, and the fire gilding is mostly present and intact (approximately 85% complete)

There is approximately 15mm of edge metal missing off the back, which you can just see on the left hand side of the photograph of the rear of the instrument - it is such a minor defect it's not really noticeable by eye, but you can feel it with your fingers.

The adjusting screw on the back works perfectly, and very slowly, so fine adjustment is much easier than the later models that were much livelier to adjust.

Dimensions:
Diameter excluding neck and ring: 51mm
Thickness: 20mm

This instrument has been professionally cleaned and serviced, and is in excellent working condition. It is approximately 160 years old.

ANTIQUE SILVER
POCKET BAROMETER / ALTIMETER
BY
CHADBURN & SON
LIVERPOOL

Hallmarked silver - year mark rubbed and no longer legible, but estimated circa 1880. Silvered dial in super condition with silvered outer altitude dial adjusted by a safety "keyless action" (turning the knurled knob inside the ring) - this mechanism has a safety action, like a watch crown, that has to be pulled out to adjust, then pushed back in to disengage the gear and so prevent accidental moving of the set index.
The neck and the ring both carry the lion passant silver mark. The back plate is engine turned with a circular centre for engraving.
The instrument is in excellent cosmetic and working condition. It has passed the plastic bag test, and has also been compared alongside a master barometer, which it follows correctly. The movement has been cleaned and serviced. The original bevelled crystal is in very good condition.
This barometer does not have the later, post 1868 adjustment hole on the back, but the needle is adjusted or calibrated by rotating the back cover of the instrument. The front bezel rotates to set the altitude, the back rotates to set the needle.

DIMENSIONS
Diameter excluding neck and ring: 42mm
length including neck and ring: 69mm
Thickness: 20.5mm
Weight: 46g

DIAMETER 53.5mm (excl crown)

DEPTH 19mm

WEIGHT INCLUDING CASE 183g

THIS IS A POCKET BAROMETER THAT INCORPORATES AN ALTITUDE SCALE ON THE OUTER CASE WALL, AND A 3-MOVEMENT CIRCULAR SLIDE RULE COMPUTER UNDER THE GLASS.  MANUAL INPUT OF THE KNOWN VARIABLES, SUCH AS WIND DIRECTION, BAROMETRIC PRESSURE, AND WHETHER THE GLASS IS RISING OR FALLING GIVES A LETTER, WHICH YOU THEN READ OFF AGAINST THE TABLE ON THE REVERSE OF THE INSTRUMENT OR ON THE IVORINE DISC SET INTO THE INSIDE OF THE LID - THIS WILL GIVE AN ACCURATE FORECAST FOR THE NEXT 24 HOURS.  IT DOES WORK!

THE BLUED STEEL DIAL CAN BE SET FOR ALTITUDE OR ADJUSTMENT BY ROTATING THE BACK PLATE OF THE INSTRUMENT, OR FOR FINE ADJUSTMENT THERE IS THE USUAL ADJUSTMENT SCREW IN A HOLE ON THE BACK PLATE.  THE WIND DIRECTION IS SET BY ROTATING THE FRONT BEZEL
THE KNURLED CROWN ADJUSTS THE CENTRAL ROTATING DISC ON THE DIAL

THE ORIGINAL GLASS IS IN VERY GOOD CONDITION - THE SILVERED DIAL COMPONENTS ARE IN GOOD CONDITION, THOUGH SOME LIGHT MARKS CAN BE SEEN WHERE THE NEEDLE HAS RUBBED AGAINST THE CENTRAL DISC IN THE PAST, BUT IT NO LONGER TOUCHES THAT DISC, HAVING BEEN ADJUSTED - THE GILT HAS SOME MARKS BUT IS GENERALLY MORE THAN 90% INTACT - THE MAIN LOSS OF GILT IS ON THE HANGING RING

THE CASE IS IN FAIRLY GOOD CONDITION - THE HINGE IS GOOD AND THE CASE CLICKS CLOSED AND OPENS WITH THE PUSH OF THE BUTTON UNDER THE MOROCCO LEATHER COVERING AT 3 O'CLOCK.

THESE ARE FAIRLY RARE INSTRUMENTS
