Year: 1870

page_text: LETTERS PATENT to Germond de Lavigne, of Paris, No. 10, Boulevard
St. Michel, for the Invention of "IMPROVEMENTS IN THE APPLICATION OF
CORK FOR PREVENTING LOSS OF HEAT BY RADIATION, AND ALSO FOR PROTECTING
BODIES AGAINST HEAT."
Scaled the 30th August 1870, and dated the 17th March 1870.
PROVISIONAL SPECIFICATION left by the said Germond de Lavigne
at the Office of the Commissioners of Patents, with his Petition,
on the 17th March 1870.
I, GERMOND DE LAVIGNE, of Paris, No. 10, Boulevard St. Michel, do
hereby declare the nature of the said Invention for "IMPROVEMENTS IN
THE APPLICATION OF CORK FOR PREVENTING LOSS OF HEAT BY RADIATION, AND ALSO
FOR PROTECTING BODIES AGAINST HEAT," to be as follows:
This Invention has for its object the employment of cork for preventing
loss of heat by radiation, as also for protecting bodies against heat.
For the first named purpose, objects such as steam pipes, or hot water
or hot air pipes, steam boilers, reservoirs of hot water, receptacles

page_text: containing hot food, and the like, are covered with a casing of cork
either in sheets, picces, or powder, being retained by any suitable outer
casing. For the second named purpose, reservoirs or conduits for cold
water, or ice houses, or localities which it is desired to keep cool, and
railway and other carriages are in like manner encased in a covering of
cork. The cork may be applied either in the form of sheets or slabs of
various thicknesses arranged as pannels, or as thin sheets rolled up into
cylinders, or as staves meeting with lap or butt joints and secured
together by collars, bands, or other fastenings, or solid cylinders or discs,
or a combination of these various forms, or of other forms, may be
employed. The non-conducting power of these casings is aided by a'
coating on one or both surfaces composed of oil colour mixed in about
equal proportions with cork dust.

filed by the said Germond de Lavigne in the Great Seal Patent
Office on the 17th September 1870..

This Invention has for its object the employment of cork for preventing
loss of heat by radiation, as also for protecting bodies against heat.
For the first named purpose, objects such as steam pipes, or hot water
or hot air pipes, steam boilers, reservoirs of hot water, receptacles
containing hot food, and the like, are covered with a casing of cork
cither in sheets, pieces, or powder, being retained by any suitable outer
casing. For the second named purpose reservoirs or conduits for cold
water, or ice houses, or localities which it is desired to keep cool, and
railway and other carriages, are in like manner encased in a covering of
cork. The cork may be applied either in the form of sheets or slabs of
