IMPROVEMENTS IN. STEAM MOTORS
Year: 1869

page_text: LETTERS PATENT to Marc Hyacinthe de Goësbriand, of No. 37,
Boulevard Bonne Nouvelle, Paris, in the Empire of France,
Gentleman, for the Invention of "IMPROVEMENTS IN. STEAM
MOTORS."
Scaled the 19th November 1869, and dated the 24th May 1869.
PROVISIONAL SPECIFICATION left by the said Marc Hyacinthe
de Goësbriand at the Office of the Commissioners of Patents, with
his Petition, on the 24th May 1869.
I, MARC HYACINTHE DE GOESBRIAND, of No. 37, Boulevard Bonne
Nouvelle, Paris, in the Empire of France, Gentleman, do hereby declare
the nature of the said Invention for "IMPROVEMENTS IN STEAM MOTORS,"
to be as follows:-
My machine may be compared to a turbine moved by steam in lieu of
water, the motor being enclosed within the condenser. Two pumps
suffice for injection and extraction, and the extraction pump worked

page_text: by the same crank as the injection one, and like it an exhaust and force
pump sends the condensed steam directly into the boiler.
On the accompanying Drawing forming part of this my Provisional
Specification A indicates cavities for admission of steam; A', the
condenser; B, pipe for transmission of steam arriving in A; 1, admission
cock; 2, injection cock; P, injection pump; p, feed pipe of injection
pump; 3, cock of feed pipe; P, extraction pump; c', extraction pipe;
p', pipe through which condensed steam is forced by pump P" into the
boiler; 4, cock for delivering condensed steam to boiler; 4, waste pipe;
6, purge cock; T, piston and connecting rods; X, driving shaft;
m, starting handle.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Marc Hyacinthe de Goësbriand in the Great
Scal Patent Office on the 23rd November 1869.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, MARC
HYACINTHE DE GOESBRIAND, of No. 37, Boulevard Bonne Nouvelle,
Paris, in the Empire of France, Gentleman, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Twenty-fourth day of May, in the year of
our Lord One thousand eight hundred and sixty-nine, in the thirty-
second year of Her reign, did, for Herself, Her heirs and successors, give
and grant unto me, the said Marc Hyacinthe de Goësbriand, Her special
licence that I, the said Mare Hyacinthe de Goësbriand, my executors,
administrators, and assigns, or such others as I, the said Mare Hyacinthe
de Gousbriand, my executors, administrators, and assigns, should
at any time agree with and no others, from time to time and at
all times thereafter during the term therein expressed, should and
lawfully might make, use, exercise, and vend, within the United
Kingdom of Great Britain and Ireland, the Channel Islands, and
Isle of Man, an Invention for "IMPROVEMENTS IN STEAM MOTORS," upon
the condition (amongst others) that I, the said Marc Hyacinthe de
Goësbriand, my executors or administrators, by an instrument in
writing under my, or their, or one of their hands and seals, should

page_text: particularly describe and ascertain the nature of the said Invention,
and in what manner the same was to be performed, and cause the
same to be filed in the Great Seal Patent Office within six calendar
months next and immediately after the date of the said Letters
Patent.
NOW KNOW YE, that I, the said Marc Hyacinthe de Goësbriand, do
hereby declare the nature of my said Invention, and in what manner
the same is to be performed, to be particularly described and ascer-
tained in and by the following statement :-
My machine may be compared to a turbine moved by steam in lien
of water, the motor being enclosed within the condenser. Two pumps
suffice for injection and extraction, the extraction pump worked by the
same crank as the injection pump and being like it a suction and force
pump
sends the condensed steam direct into the boiler.
The construction and arrangement of my improved motor will be best
understood by reference to the Sheet of Drawing hereunto annexed, and
to the letters of reference placed thereon.
A, casing of cylinder containing the valve and steam entrance and
extraction; A', plate fixed by six screws to keep the piston in the
cylinder; P, steam piston turning on the axle a; G, bucket of steam
piston; C, valve forming pressure surface at the part C'; V, entrance of
steam which penetrating between the surface of the valve C, and the
surface C (forming one face of the solid part of the bucket) and
expanding against the fixed part C forces the part C' to open. During
this time the valve C sliding on the surface S of the bucket rises again
in the part A (of the cylinder casing) until it falls into the following
bucket, and so on until a continuous rotation is produced; E, extraction;
B, main frame to which the cylinder casing is fixed; b, connecting rod
for working the extraction and feed pumps; b', small framings supporting
the horizontal shaft.
The number of buckets may be increased or lessened in the same
piston, and my Invention consists in causing a wheel to move by means
of moveable buckets and a fixed valve, substantially as described.
The advantages offered by the machine are that it occupies very little
space, and that it may be applied to all kinds of manufacturing purposes

page_text: without the aid of ordinary shafting and driving gear, also that as
it can be taken to picces with very light tools repair is easy.
In witness whereof, I, the said Marc Hyacinthe de Goësbriand,
have hereunto set my hand and seal, this Twentieth day of
November, in the year of our Lord One thousand eight hundred
and sixty-nine.
