Sundial, Finely Engraved, Signed: Tho [Thomas] Heath (1698-1773), London
Date/Period: 1720-1750 (Maker was active 1721 to the 1760s)

Antique Slide Lid Document Box with Lock & Key, Original Red Paint New England, entire view

Measurement: Height: 7.75" diameter: 11.75"

Material: Brass

Condition: Very good, as expected…weatherworn displaying dark surface with
verdigris

Additional Information: This is a very sophisticated and complex sundial made by
esteemed scientific instrument maker Thomas Heath (1698-1773), who worked in
London from 1721 until the late 1760 s. It is finely engraved allover.

The sundial allows the viewer to calculate the difference between the apparent and
the mean solar time, allowing him to accurately set his watch or clock. If you were
wealthy enough to own a lantern clock you needed a sundial to establish time allowing
you to set the clock.

This dial shows the Equation of Time (Natural Days). which describes the discrepancy
between two kinds of solar time. The word equation is used in the medieval sense of
"reconcile a difference". The two times that differ are the apparent solar time, which
directly tracks the diurnal motion of the Sun, and mean solar time, which tracks a
theoretical mean Sun ( as shown by a clock) with uniform motion along the celestial
equator. Apparent solar time can be obtained by measurement of the current position
(hour angle) of the Sun, as indicated (with limited accuracy) by a sundial. Mean solar
time, for the same place, would be the time indicated by a steady clock set so that over
the year its differences from apparent solar time would have a mean of zero.

Patent or Salesman’s Cased Model,
Sled with Brake & Documents
Date/Period: 1870s

Patent or Salesman’s Cased Model, Sled with Brake & Documents, entire view

Measurement: Case: 17.75 x 7.5 x 9.5", sled: 17” x 7.75 x 6 3/8”

Material: Oak, walnut, steel, and small rubber drums, braking mechanism may not
be complete, please call David to discuss.

Condition: Very good

Additional Information: An expertly constructed snow sled of mortise and tenon
joinery. The sled is contained within a dovetail joined lidded box made of poplar.
Within the case are a letter written on Carr, Crawley & Devlin, a partnership formed in
1871 and directed by Thomas Devlin a manufacturer and, capitalist.
The company was in the hardware trade and other businesses. The brief document
speaks to castings, lead time and credit. Perhaps when the sled or braking system was
manufactured, if it went into production, the maker contracted with Carr, Crawley &
Devlin to cast parts for braking system.

A memorandum dated 1878 from Towner, Landstreet & Co. having a footer for
“Goodyear’s Rubber House” discusses an order…the sled brake system utilizes two
small rubber pieces. Of course, this is solely conjecture. Also included are a postcard
and envelope.

Inclinometer, Plumb and Level Indicator,
Rufus Porter, Circa 1847, Rare Type I
PLUMB AND LEVEL INDICATOR
MANUFACTURED BY R. PORTER NEW YORK

An extremely rare first type inclinometer by famed inventor, artist and publisher of Scientific
American, true Renaissance man- Rufus Porter…only the third we have handled in nearly forty-years!
A very special piece of Americana that speaks to multiple collecting interests;
appealing to level/tool enthusiasts and to followers of Rufus Porter.

Porter inclinometers of any type are very rare, the first type is almost unknown.
This is destined to be the highlight of any advanced collection of inclinometers/levels.

The illustrated dial is printed on paper; dial face depicts masons using the device to construct/level a wall.
The engraving is clear and mostly complete with some water damage and three small paper losses at lower left,
the indicator needle retains 50% of original bluing and about 85% of weight gilding. The 8.75” glass appears to be original.

Based on when Porter first advertised his inclinometer in Scientific American (Vol. 2, No. 11, Dec. 5, 1846),
it is believed he developed this device in early 1846. While the later versions are marked “patent applied for”,
no known patent was granted. Whereas so few of Porter's levels are known,
we assume that he didn't produce these in quantity or for very long.

Spandrels center the chapter ring framing depiction of masons using the device.
Finely joined walnut frame retains original finish; likely original glass.
