WILLIAM PHILLIPS THOMPSON of the Agency for Foreign Patent Solicitors
6 Lord Street Liverpool in the County of Lancaster and of 323 High Holborn in
the County of Middlesex Civil Engineer "IMPROVEMENTS IN AND APPER-
TAINING TO BURNERS FOR GAS JETS" A communication from abroad from
Monsieur Paul Costes, Mechanician, of Bourges in the Department of Cher,
France.
The following is a translation of the communication as forwarded to me.
"The Invention which forms the subject of this application relates to a system
"of gas burner which I have designed and which presents great advantages not
merely in economy of gas but in beauty of flame.
"
My system is characterized by the addition of a sort of filtering box divided
"into many compartiments by perforated diaphragms or divisions of such character
"that the gas before arriving at the orifice of the burner has been subjected to
numerous deviations breaking its direct march and thus diminishing its velocity,
"and has had to traverse a filtering material capable of retaining all impurities
that it could otherwise carry along with it

"I employ by preference but not exclusively to filter and purify the gas a
sponge which has been previously partly burnt (consumée). This sponge fills
one or several of the compartments arranged in the interior of the ordinary
"burner.
"It results from this disposition that the gas, sifted by passing through the
compartments of the filtering box is purified of all the impurities which it could
bring along with it, impurities which could only diminish its power of lighting,
and that, its speed being greatly reduced no matter what the pressure may be,
"it is completely burned, whilst in ordinary burners there is a notable modicum
"of gas which escapes combustion by reason of the speed of escape due to the
pressure
E
"The employment of such arrangement produces in the consumption of gas an
economy that I estimate at thirty four per cent.

"I have represented upon the Drawing annexed to the present Specification a
specimen of a burner of my system. Fig. 1 is a longitudinal section of the
"burner. Figs. 2, 3, 4, 5, and 6 show in plan details of the filtering box-a is the
" chamber already spoken of which contains the sponge. Above this chamber is
" found a copper washer b preferably pierced with three holes. Above this is a
ring c and a fine metallic gauze d. Below the chamber a is placed metallic
gauze e, a disc f in which is cut a diametrical slot, a ring g and lastly the
"washer h which is pierced with four holes equally distant from the centre.
"will be seen that the disposition of the passages made in the various discs is such
that these passages do not correspond and that consequently they form bate
plates to diminish the speed of the gas. The rings c and g bear up on two
"shoulders made in the burner A. These have for their object the prevention of the
forcing of the filtering box under the action of a strong pressure. I bave made
by preference my washers of copper because the gas does not form swarf with
"this metal and also there is less risk of the orifices getting choked
"

"It will be understood that I do not limit myself either to the number of washers
"I use or of orifices contained therein, as these may be widely varied without
departing from the principle of my Invention'
