Year: 1863

page_text: LETTERS PATENT to Joseph Gustave Pinède, of Liancourt, in the Depart-
ment of the "Oise," in the Empire of France, Mechanician, for the
Invention of "IMPROVEMENTS IN APPARATUS FOR REGULATING THE SPEED OF
STEAM AND HYDRAULIC ENGINES."
Sealed the 29th December 1863, and dated the 6th August 1863.
PROVISIONAL SPECIFICATION left by the said Joseph Gustave Pinède
at the Office of the Commissioners of Patents, with his Petition, on
the 6th August 1863.
I, JOSEPH GUSTAVE PINEDE, of Liancourt, in the Department of the "Oise,"
in the Empire of France, Mechanician, do hereby declare the nature of the
said Invention for "IMPROVEMENTS IN APPARATUS FOR REGULATING THE SPEED OF
STEAM AND HYDRAULIC ENGINES," to be as follows:-
My apparatus is composed, firstly, of a knee or elbow pipe of cast iron or
bronze, and of round or oval shape; secondly, of a square shaped valve pinned
on to an axle. This valve is placed in the centre of the elbow pipo in a
cylindrically bored part, in which it must turn following the rotary motion of the
axle; thirdly, of a stuffing box and gland, or lid, which forms joint, and serves to
support the axle of the valve, this stuffing box lid or gland is fixed to the elbow
pipe by two screws and nuts; fourthly, of a bronze plug or stopper serving also
to support the axle of the valve, this stopper forms joint at the opening of the
elbow pipe, which serves for the passage of the valve. and is fixed to the said pipo
Or, I make the valve of half square form, and the stopper with

page_text: a hollow forming stuffing box, and receiving a small stuffing box lid or gland,
the bottom of which is pierced with a small circular hole. A ring, flange, or
thimble, united to the elbow pipe by two screws with nuts, holds the stuffing
box lid or gland against the stopper, then a hollow screw passing through the
thimble or ring presses against the small stuffing box lid or gland, and
applies its hollow part against that of the said lid or gland. This apparatus,
by its method of adjustment, presents the advantages of a cock without its
stiffness of action, it is suitable to every sort of regulator to engines of any
power, and by its use a regular action is obtained.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Joseph Gustave Pinéde in the Great Seal Patent Office
on the 27th January 1864.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JOSEPH
GUSTAVE PINEDE, of Liancourt, in the Department of the "Oise," in the Empire
of France, Mechanician, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Sixth day of August, in the year of our Lord One
thousand eight hundred and sixty-three, in the twenty-seventh year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto me, the
said Joseph Gustave Pinéde, Her special licence that I, the said Joseph
Gustave Pinéde, my executors, administrators, and assigns, or such others as I,
the said Joseph Gustave Pinéde, 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 APPARATUS FOR REGULATING THE SPEED OF STEAM AND HYDRAULIC
ENGINES," upon the condition (amongst others) that I, the said Joseph Gus-
tave Pinéde, my executors or administrators, by an instrument in writing
under my, or their, or one of their hands and seals, should parti-
cularly 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 Joseph Gustave Pinéde, do hereby
declare the nature of my said Invention, and in what manner the same is

page_text: to be performed, to be particularly described and ascertained in and by
the following statement, reference being had to the Sheet of Drawing here-
unto annexed, and to the figures and letters of reference marked thereon.
My improvements consist in two arrangements of apparatus, which I term
"valve-cocks," for regulating the speed of steam and hydraulic engines, both
of them being based on the same principle, and having the greatest analogy.
The first arrangement is composed, firstly, of a cast-iron or bronze knee
or elbow pipe or casing; secondly, of a square-shaped valve pinned on an axle,
this valve is placed in the centre of the pipe in a cylindrically bored part square
with the square hole of the tubing; thirdly, of a stuffing box, and gland, or
lid, which forms joint, and serves to support the axle of the valve. At the part
opposite the stuffing box gland is a bronzed stopper fixed by screws, serving
to receive the end of the axle of the valve, and to stop the bored part in
which the valve is adjusted. Figures 1, 2, and 3 shew this arrangement.
a, pipe or casing of oval shape; b, square-shaped valve; 6', part of the pipe
turned true, in which the valve turns freely in every direction, which renders
the transmission of motion from the regulator to the axle of the valve easy of
execution; c, axle or rod of the valve; d, stuffing box lid or gland; d', stuff-
ing box; e, stopper fixed by screws, forming joint at the opening, which serves
for the passage of the valve into its cylindrical part 6'; f, section of the square
conduit, which traverses the tube from end to end, receives at one side the
inlet pipe, and on the other is fixed to the steam engine.
In the second arrangement the modifications in the above are, firstly, the
pipe is round; secondly, the valve is of half square shape; thirdly, the stopper
is cylindrical, and has a hollow part forming stuffing box; fourthly, a stuffing
box lid or gland, pierced with a small circular hole, is applied on the said
stopper; fifthly, a ring, flange, or thimble, fixed to the tube by two screws
with nuts, secures the stopper and its stuffing box gland; sixthly, and lastly,
a hollow screw traverses the ring, and causes pressure against the stuffing box
lid. The hole of the stuffing box gland, which is at the end of the axle of the
valve, communicates with that of the hollow screw, and their object is to
permit the free escape of the steam, which in passing round the axle might
press on the end of the said axle if it found no outlet. Figures 1*, 2*, 3*,
and 4, illustrate this second arrangement.
a, cast-iron pipe; b, bronze valve, turning freely and in every direction in
the cylindrical chamber 6', it serves to regulate the passage of the steam; い
turned part of the pipe in which turns the valve; c, axle on which the valve is
fixed by a pin; c, pin; d, bronze stuffing box lid or gland; d, stuffing box;
e, bronze cylindrical stopper, closing the opening of the pipe; f, small stuffing

page_text: box lid coming on the stopper, the interior of which forms stuffing box; f¹,
stuffing box; 9, ring or thimble fixed to the pipe by two screws with nuts;
h, pierced screw traversing the ring; i, screws with nuts; j, rectangular
opening, slightly widened outside on the two large sides, traversing the pipe
throughout, intended for the passage of the steam, water, or other body; k, iron
ring adjusted on the pipe, and separating the stuffing box d¹ from the
chamber; 1, iron ring, adjusted on the stopper of which it forms the bottom.
My "valve cock" by its method of adjustment presents the advantage of a
cock without its stiffness in moving, is casily fitted, is subject to little wear,
and does not set or fix.
This description of cock is suitable to every system of regulator and machines
of any power, and by its use the regular working of the machine is assured.
The Drawings hereunto annexed giving all the indications necessary to the
comprehension of my Invention, I will here terminate my description with the
observation that, if required, the shape, the dimensions, as well as the materials
used may vary; and that I claim the exclusive application of this valve-cock
wherever it can be applied to regulate the passage of steam, water, gas, or
other bodies.
In witness whereof, I, the said Joseph Gustave Pinède, have hereunto set
my hand and seal, this Eleventh day of January, in the year of our
Lord One thousand eight hundred and sixty-four.
