Year: 1874

page_text: PROVISIONAL SPECIFICATION left by Charles Demynter at the Office
of the Commissioners of Patents, with his Petition, on the 3rd
February 1874. A communication from abroad by François Le
Noir, 37, Rue Grange-aux-Belles, Paris.
I, CHARLES DEMYNTER, 48, Oxford St., London, W., do hereby
declare the nature of the said Invention for "A NEW HYDRO-CARBONE
PURIFICATORY APPARATUS FOR THE ILLUMINATING Gas," to be as follows:-
The Invention consists in a complete purification of illuminating gas
by a carburatory process; being exceedingly simple it offers great
advantages for common use, and does not require any absorbent or
porous material, cotton, or pumice stone to effect the carburation, the
carburating fluid being in direct contact with the gas to be purified.
The apparatus differs entirely with all those used untill now without
success.
The gas enters at one end of the apparatus, in the inside of which it
follows a regulated motion by passing through partitions which are
perforated alternately on opposite sides of the chamber, compelling the
gas to take a serpentine course over a liquid hydro-carbure bath, and it

makes its exit from it saturated with the volatile particles of the fluid.
The successive supply of the liquid is effected by a Mariotte pipe or
flask with a branch leading to a chamber above.
Another valuable feature is the facility of expelling in due time the
heavy products accumulating at the bottom of the carburating chamber.
By referring to plans annexed to this petition the apparatus and his
functions may be soon explained.
The facility of removing the heavy products just spoken of is obtained
by the adoption of a two-branched cock in a small chamber which is
situated between the carburation chamber and the reservoir which
receives the heavy products.
Everybody will understand the adaptability and the working of my
apparatus by referring to the annexed Drawing, where it is represented
in elevation (Fig. 1), in a vertical section (Fig. 2), and in the plane
(Fig. 1), in a vertical section (Fig. 2), and in the plane (Fig. 3).
The Fig. 4, 5, & 6 are views in detail of the two-branched cock
belonging to the intermediate emptying chamber.
My apparatus is composed of four distincts parts, id est, a reservoir A
for the liquid; a carburation chamber B receiving the liquid from the
reservoir A by means of a tube or Mariotte flask provided with a cock C; ;
an intermediate chamber C provided with a two-branched cock c; and
finally, an emptying reservoir D to receive the residium from the car-
buration chambers, which is composed of heavy products.
The hydroc-arbonic fluid is introduced in the reservoir A through the
screw cocks d, d, and descents into the reservoir A through the Mariotte
pipe a into the carburation chambers B. The chamber is divided by
partitions fff, which are perforated at alternate sides, and is provided
with a pipe or siphon g which conducts the waste fluid into the reservoir D.
The effect of the Mariotte pipe is to maintain the fluid in the chamber B
at an uniform level, and to conduct the fluid from the reservoir A to the
chamber B drop by drop, according to the quantity required for the
carburation of the gas.
The intermediate reservoir for emptying C, as I stated above, regulates
in a proner way the dropping of the heavy products which remain in the

page_text: renders it possible to establish communication between B & C, but there
is never a direct dropping from B to D. In the Fig. 4 there is a com-
munication between B & C; in the Fig. 6 it is between O & D. At the
side of the carburation chamber B are fixed two pipes h, h, for the
entrance and exit of the gas. These two pipes are connected by a
transverse one, and provided with a cock K.
When the gas requires purifying the cock K is closed, and the two
others e, e, are opened, and on the contrary if the gas is to be used
without carburating it then the cock k is opened, & the two others e, e,
are closed.
The apparatus is provided with sight holes and waste cocks in order
|that any one may be able to see into it & cleanse it when necessary.
