Year: 1858

page_text: LETTERS PATENT to François Jules Emile Oosterlinck, of Paris (France)
Gentleman, for the Invention of "AN IMPROVED VALVE OR PLUG FOR THE
PASSAGE OF WATER OR OTHER FLUIDS.".
Sealed the 25th September 1858, and dated the 1st April 1858.
PROVISIONAL SPECIFICATION left by the said François Jules Emile
Osterlinck at the Office of the Commissioners of Patents, with his
Petition, on the 1st April 1858.
I, FRANÇOIS JULES EMILE OOSTERLINCK, of Paris (France) Gentleman, do
hereby declare the nature of the said Invention for "AN IMPROVED VALVE OR.
PLUG FOR THE PASSAGE OF WATER OR OTHER FLUIDS," to be as follows:-
The Invention relates to an improved valve or plug applicable to the mains:
or other pipes for conducting water or (lighting) gas. The lower part of this.
valve is provided with a box or reservoir for collecting the sand or other
solid matters deposited from water, or the condensation water of gas, which
solid matters or condensation water may by this arrangement be abstracted
without allowing any undue escape of water or gas from the supply to take
place.
The barrel of the valve is fixed to the mains or conducting pipes in the
usual manner by proper flanges and screw bolts, the same has its entrance and

page_text: exit openings contracted gradually to a rectangular form, and inclined towards
each other so as to form two inclined sides, between which is inserted a
trapezoidal quadrangular prism forming the plug for the valve for closing up
the space left between the two rectangular openings; the top and bottom of
this plug are tapped for the insertion of a vertical lifting screw, by which the
plug may be lifted up in its highest position when the same closes the two
rectangular openings, or lowered till the plug is introduced in the reservoir, in
which state the valve is fully opened, and the water or gas allowed to pass
through freely, at the same time permitting them to deposit the solid matters
or the condensation water in the said reservoir, which when required may
be taken off from the body of the valve, cleaned from its contents, and then
attached again to this latter; or in case the valve is to serve for gas supply,
the reservoir is provided at the bottom with a hole closed by a plug, by means
of which the condensation water may be let off.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said François Jules Emile Oosterlinck in the Great Seal Patent
Office on the 1st October 1858.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, FRANÇOIS
JULES EMILE OOSTERLINCK, of Paris, France, Gentleman, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the First day of April, in the year of our Lord One
thousand eight hundred and fifty-eight, in the twenty-first year of Her reign,
did, for Herself, Her heirs and successors, give and grant unto me, the said
François Jules Emile Oosterlinck, Her special licence that I, the said François
Jules Emile Oosterlinck, my executors, administrators, and assigns, or such
others as I, the said François Jules Emile Oosterlinck, my executors, admi-
nistrators, and assigns, should at any time agree with, and no others,
from time to time and at all times thereafter during the term therein ex-
pressed, 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 "AN IMPROVED VALVE OR PLUG FOR THE PAS-
SAGE OF WATER OR OTHER FLUIDS," upon the condition (amongst others) that
I, the said François Jules Emile Oosterlinck, my executors or administrators,
by an instrument in writing under my, or their, or one of their hands and
seals, should particularly describe and ascertain the nature of the said Inven-

page_text: tion, 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 François Jules Emile Oosterlinck, do
hereby declare the nature of the said Invention, and in what manner the
same is to be performed, to be particularly described and ascertained in and
by the following statement:-
The Invention relates to improved construction of valves, stop cocks, or
plugs for mains or other pipes for conducting water or other liquids or gas.
In the annexed Drawings Fig. 1 shows a longitudinal sectional view of one
of my improved valves or plugs, whereas Fig. 2 shows a transverse sectional
view of the same; Fig. 3 shows a longitudinal sectional view of another con-
struction of the valve, of which Fig. 4 shows a transverse sectional view. In
these Figures corresponding parts are indicated by the same letters of re-
ference. A is the barrel of the valve, provided with suitable flanches B, by
which the same is connected in the usual manner to the ends of the mains or
other pipes; the entrance and exit openings C and D contract gradually
towards the centre, so as to leave in the points b, c, and d, e, openings of a
rectangular form, which may be closed when required by means of the plug
E, in the top of which is cut a female screw, through which passes a male
screw G, the lower or blank part H of which revolves in a small pan 1 in the
reservoir J with which the valve is provided; the screw G passes at the top
of the valve through an opening in the centre of a sort of hollow cap, oil or
stuffing box K fitted on the top of the valve, and fixed thereto by means of
two screws L, suitable washers of leather or other suitable material being
interposed between the joints in order to keep them perfectly water or air
tight; the upper end M of the screw blank is further provided with a square
head in order to allow of actuating the screw from the outside of the valve.
The plug E is made hollow, and presents two flat surfaces E' and Es fitting
exactly against the above mentioned rectangular openings in the barrel of the
valve, which openings are lined all round with bronze, antifriction metal, or
any other suitable metal or material; whereas on the two side ends the plug
is provided with two wings O and O gliding in two vertical grooves managed
in the interior of the barrel. I further prefer to have the plug made hollow, so
as to give it greater lightness, and consequently allowing the same to be casier
lifted up or lowered down by means of the screw G; by turning the screw in
one direction the plug is caused to ascend, whereas by turning the same in the
opposite direction the same is pushed down in the interior of the square

page_text: reservoir J fitted at the under side of the valve, the height of which reservoir
corresponds with that of the plug, and has at the bottom an opening P, closed
by a screw or plug Q, for allowing to extract sand, water, or any other
materials that would have deposited in the reservoir J, which latter is fitted
at the bottom of the valve barrel by means of a pair of screw bolts R and a
washer interposed between the joints. In the points band d I prefer to
have a sort of elevated edge g and h formed for further arresting any matters
that would be wished to be prevented from passing through the cock or valve.
When the valve is serving for gas purposes the reservoir would after a certain
time have become filled with water; the same may be drawn off by the
-opening P after having previously lifted the plug E to its highest position; or
in case the valve is applied to water mains, and the reservoir would after a
'certain time have become filled with sand or other matters, then after having
closed the valve, by lifting the plug E the entire reservoir may be taken off
and cleaned, and then fixed again in its original position.
Fig. 3 represents a longitudinal vertical, and Fig. 4 a transverse vertical
section, of a modification of the above-described arrangement, showing also
the manner of fixing to the plug the compressible substance with which the
same is fitted. In this arrangement the barrel A is provided in A¹ and A2
with a projecting rim, against which fits the plug E, over which latter is
spread a piece of leather or other compressible material-firmly held in position
by being inserted in a groove k fitted round the plug, in which groove the
material is kept fixed by means of a ring ; the plug may have only one or
both of its sides provided with this arrangement. In order further to keep as
much space as possible in the interior of the reservoir J, I force the plug to
turn round a-spindle m by means of a stop fixed underneath, for instance, in
x, whereas this spindle m turning with its extremities or trunnions in two
rings forming the lower ends of a forked piece n fitting and gliding in tho
part S of the valve barrel, and in which fork acts the screw G. For opening
this valve the screw G is to be turned so as to cause the part n to descend
with the plug, but this latter being prevented by the stop x, the same con-
sequently will be forced to assume the horizontal position without closing
entirely the reservoir J, but leave sufficient space for allowing the sand or
'other materials to deposit therein, whereas the fork n is lowered, and permits
the fluids to pass freely through the opening left between the arms of this
'fork n.
I must add here that the leather or other compressible material
'made use of as a covering for the plug E is further fixed thereon by a metal
plate E3 and screw E.

page_text: Having thus described the nature of my Invention, and the manner of
operating the same, I claim as my Invention the above-described arrange-
ments of valves, plugs, or cocks to be applied to mains or other pipes for
conducting gas, water, or other fluids.
In witness whereof, I, the said François Jules Emile Oosterlinck, have
hereunto set my hand and seal, this Twenty-ninth day of September,
One thousand eight hundred and fifty-eight.
Witness,
J. SOUTH.
