Office of the Commissioners of Patents, with his Petition, on the 15th
October 1867.-A communication from Leffert Ryerson Cornell,
residing in the City and State of New York, United States of America.
I, HENRI ADRIEN BONNEVILLE, of the British and Foreign Patent Offices,
38, Porchester Terrace, Bayswater, in the County of Middlesex, and 24, Rue
du Mont Thabor, Paris, in the Empire of France, Patent Agent, do hereby
declare the nature of the said Invention for "IMPROVEMENTS IN APPARATUS FOR
SUPERHEATING STEAM AND OTHER VAPOURS," a communication from Leffert
Ryerson Cornell, a person resident in the City and State of New York,
United States of America, to be as follows:-
The Invention communicated to me consists, first, in a novel construction
and arrangement of pipes or tubes for the introduction and passage of steam
or other vapours for the purpose of superheating the same; the main principles
of which construction consist, first, in providing barriers to the passage of the
steam or other vapour, and in so running or locating the pipes or tubes that
the steam or other vapour will be made at points of its passage through the
tubes to strike against the sides or surfaces thereof, and thus have its particles, as
it were, so broken or separated as the more fully and perfectly to be subjected
to the action of the heated currents circulating about or around the tubes of
the superheater, either more or less, as the case may be; and, second, in so
constructing the pipes composing the superheater, that at the points thereof

page_text: where the steam or other vapour impinges or strikes against the sides of the
pipes and becomes broken up into particles, as above stated, such steam or
other vapour will then be allowed to expand, when being again contracted in
its further passage onward a new column of steam or other vapour, as it were,
is formed and exposed to the action of the heated currents until it is again
broken up as before, when again expanding and becoming contracted it passes;
third, in so constructing the superheater for beating the steam or other vapour
with the boiler or boilers from which such steam or other vapour is being and
has been previously generated, that the superheated steam or other vapour
can be conducted back into the boiler, and there made to act upon and diffuse
itself entirely or thoroughly; the water or other liquid or material from which
the said steam or other vapour is being generated, whereby with such superheated
steam or other vapour thus conducted back, the generation of the steam or
vapour can be in the most efficient, practical, and economical manner increased
beyond all calculations hitherto known, and the fire directly under the boiler
or boilers thereby enabled to be dispensed with; provided a proper calculation
of steam has been, first established through the apparatus.
These improvements are represented, in the accompanying Drawings, being
a plan view of the apparatus, in which A is the boiler; B, the masonry, sup-
porting the boiler; C, the grate; D, the pipe leading into the cylinders F, F;
E, safety valve; F, F, the cylinders; G, G, the masonry supporting the
cylinders; H, cross heads dividing the cylinders into a series of chambers I;
J, a series of arched pipes connecting the two cylinders; K, pipe for the
escape of the condensed steam or water; M, R, pipes leading the super-
heated steam into the boiler; and U, check valve, to prevent the water within
the boiler from passing out through the said pipe.
