Iм- PROVEMENTS IN SLUICE COCKS
Year: 1862

page_text: LETTERS PATENT to Jean Marie Herdevin and Joseph Alexandre Jullien,
Ingénieurs, 18, Rue Gaillon, Paris, France, for the Invention of "Iм-
PROVEMENTS IN SLUICE COCKS."
Sealed the 31st October 1862, and dated the 3rd May 1862.
PROVISIONAL SPECIFICATION left by the said Jean Marie Herdevin
and Joseph Alexandre Jullien at the Office of the Commissioners of
Patents, with their Petition, on the 3rd May 1862.
We, JEAN MARIE HERDEVIN and JOSEPH ALEXANDRE JULLIEN, Ingénieurs,
13, Rue Gaillon, Paris, France, do hereby declare the nature of the said
Invention for "IMPROVEMENTS IN SLUICE COCxs," to be as follows:-
These improvements have reference to a peculiar form and construction of
sluice cocks, whereby greater rigidity and power of resistance are obtained,
as well as facility offered in their construction. For this purpose I make
the valve box cylindrical in form, with either spherical or flat extremities,
and the valve wedge shaped, closing against the inclined faces of the inlet and
outlet pipes protruding within the said cylindrical box.

page_text: SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Jean Marie Herdevin and Joseph Alexandre Jullien in the
Great Seal Patent Office on the 3rd November 1862.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, JEAN
MARIE HERDEVIN and JOSEPH ALEXANDRE JULLIEN, Ingénieurs, 13, Rue
Gaillon, Paris, France, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Third day of May, in the year of our Lord One
thousand eight hundred and sixty-two, in the twenty-fifth year of Her reign,
did, for Herself, Her heirs and successors, give and grant unto us, the said
Jean Marie Herdevin and Joseph Alexandre Jullien, Her special licence
that we, the said Jean Marie Herdevin and Joseph Alexandre Jullien,
our executors, administrators, and assigns, or such others as we, the
said Jean Marie Herdevin and Joseph Alexandre Jullien, our execu-
tors, 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 SLUICE Cocks," upon
the condition (amongst others) that we, the said Jean Marie Herdevin
and Joseph Alexandre Jullien, our executors or administrators, by an
instrument in writing under our, or their, or one of their hands and
seals, should 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 we, the said Jean Marie Herdevin and Joseph
Alexandre Jullien, do hereby declare the nature of our said Invention, and
in what manner the same is to be performed, to be particularly described
and ascertained in and by the following statement (that is to say): —
Our improvements in sluice cocks can be practised in two different manners,
that is to say, without departing essentially from the form and general con-
struction of the same. We have adopted two different manners of connecting
and uniting the constituent parts, which we will proceed to explain in con--
junction with the accompanying Sheet of Drawings, wherein Fig. 1 is a
plan of a complete sluice cock; Fig. 2, a longitudinal sectional elevation of
same, through A; A, Fig. 1; Fig. 3,.a transverse sectional elevation of same
through B, B, Fig. 1; and Fig. 4, a detailed view of parts of said valves.

page_text: Our first mode of construction is exemplified by the full lines in the three
first Figures, the shell consisting of two main parts, the former comprising the
valve box a, a, which is cylindrical, with spherical ends, and to which is cast
one of the pipes b; and the latter comprising the second pipe c, united to the
former by a flange joint d, d, the two pipes b and c, which serve as the inlet
and outlet protrude within the said box, where their extremities are bevelled
off, and faced with brass rings e, c, attached by screws in the usual manner;
the valve fitself is of cast iron, with brass facing rings g, g, the whole having
a taper corresponding to the inclination of the inlet and outlet faces; it is
likewise pierced with two holes at right angles with one another, one of
which is perpendicular for the passage of the screw h, for raising and lowering
the valve, and the second horizontal for the passage of the nut i, in
which the screw passes; k is a cap for securing the screw; 1, a stuffing
box, to prevent leakage; and m, a plate, closing the lower opening n, through
which any foreign matter obstructing the valve can be extracted; the valve
is guided in its motion by the lateral ears protruding from the said valve,
which range in the vertical slots cast on the inner face of the box. See
Fig. 3.
Our second mode of construction is likewise exemplified by the three first
Figures, the modification being represented by dotted lines, whilst Fig. 4
serves to illustrate the manner of fixing the facing rings on the internal
extremities of the inlet and outlet pipes; in this case we also construct the
shell of our sluice valve (which is similar in shape to the former) in two
main parts, the first comprising the two pipes b and C, with lower and
central parts of cylindrical box, terminating at the dotted flange p; the
second consisting in the semi-spherical top, united to the said flange by bolts
and nuts;
the other constituent parts of the sluice valve remain the same,
except the joint d, which is suppressed, and the manner of attaching the
facing rings on the pipes, which is exemplified in Fig. 4, as in this description
of sluice valve the attachment of the pipe facings in the usual manner
would be attended with considerable mechanical difficulty, we have recourse
to molten lead for effecting the said attachment. On the right hand the
casting is represented ready to receive the ring, and on the left hand the ring
is shewn cast firmly in its place by means of the lead q. The mode of securing
the said rings is as follows:-The rings e, e, are first laid loosely in their
recesses, and the valve with its facings being run down, the said rings are
brought into contact with the facings by means of the screws r, r, four of which
to each ring; we then fill up with molten lead the annular space existing
between the external edge of the rings and the internal edges of recesses;

page_text: when the lead is set, the valve is run up, and it is then caulked tight by
hammer and appropriate caulking tools; the screws can be allowed to remain
or they may be withdrawn, and the holes run with lead; instead of running the
lead externally to the rings, we can, if requisite, secure them by running the
same in a recess formed internally to the rings.
Having thus described our improvements, together with the best manner we
are acquainted with for carrying the same into practice, we claim as our
Invention,―
Firstly, the cylindrical shape given to the valve box, whether it be terminated
by spherical or flat ends.
Secondly, the manner of forming the shell in two parts, united by the
joint d.
Thirdly, the manner of forming the shell in two parts, united by the
joint p.
And, fourthly, the peculiarities of construction of these valves, requisite for
effecting the above-mentioned purposes.
In witness whereof, we, the said Jean Marie Herdevin and Joseph
Alexandre Jullien, have hereunto set our hands and seals, this Twenty-
eighth day of October, One thousand eight hundred and sixty-two.
