Improvements in Economisers for Gas Burners.
I, CHARLES KNAEPS, of 135, Boulevard du Hainaut, Brussels, Belgium, Manu-
facturer, do hereby declare the nature of this invention, and in what manner
the same is to be performed, to be particularly described and ascertained in
and by the following statement:-
The subject of the present invention is a novel gas saving appliance or econo-
miser for gas burners which when applied in general to these latter admits of
a perfect regularity of the gas pressure being obtained, as well as of effecting
a considerable economy or saving in the gas consumption.
In the accompanying drawing is illustrated by way of example one form or
modification of the invention, and in this drawing:
:-
Fig. 1, is a view in elevation of the new economiser the cap 2, being unscrewed.
Fig. 2, is a vertical section of this economiser the cap 2 being screwed upon
the cylindrical body casing 1.
Like letters of reference indicate corresponding parts in both these two figures.
The new economiser consists essentially of a cylindrical body or casing 1, the
lower extremity of which terminates in a screw-threaded junction or union 3,
which admits of the economiser being screwed upon the supply pipe to the gas
burner (not shown in the drawing). The upper end of the cylindrical body or
casing is screw-threaded to receive a junction or union cap 2, into which is
screwed the burner.
On the interior of the cylindrical body or casing 1, upon the shoulder 4 formed
by the lower junction or union piece 3, rest, or are supported several washers
of perforated metal, of fine wire gauze etc., as indicated by the Figure 5, and
above these washers is provided filtering material 6 of any suitable description..
(such as tinder, tannin, bristles, felt, or pieces of leather incrusted). Upon
the filtering material 6 rest other washers formed of perforated metal or of wire
gauze, etc., as indicated by the Figure 7,
Lastly above the washers is screwed a perforated and screw-threaded plate
or diaphragm 8, in the upper internally screw-threaded portion of the cylindrical
body or casing 1. The plate or diaphragm 8, is provided with a central boss 9,
provided with a slit intended to receive the end of a screwdriver.
The gas which is delivered in the direction indicated by the arrow a (Fig. 2,)
is thus forced to pass through the washers 5, the filtering material 6, and the
washers 7, in order to pass out in the direction indicated by the arrow b and to
enter the burner of the gas lamp. The perforated plate or diaphragm 8, prevents
the wire gauze washers 5 and 7, as also the filtering material 6 from being raised
up by reason of the pressure exerted by the gas.
It will be obvious that the novel economiser might be of any other form
besides that shown in the accompanying drawing, that the interior surface of
the body or casing 1, instead of being cylindrical, might be provided with
houlders, steps etc., to receive and support the different washers 5, 7, (the number
of which may be such as found to be suitable or convenient) as also the filtering
material 6, and that the said economiser may be of any suitable dimensions
without in any way departing from the nature of the said invention.

page_text: Having now particularly described and ascertained the nature of my said in-
vention, and in what manner the same is to be performed, I declare that what I
claim is:
An economical or saving economiser for gas burners characterized by a body
or casing of a cylindrical or other suitable shape formed in one piece with a
suitable junction or union serving to fix the economiser upon the gas supply
pipe to the burner, this cylindrical body or casing containing any suitable num-
ber of washers of perforated metal, or of wire gauze etc., upon which is placed.
some suitable filtering material, surmounted by some washers similar to those
first mentioned, which are held in position by a perforated screw-threaded plate
or diaphragm screwed into the upper internally screw-threaded part of the
cylindrical body or casing above mentioned, and the economiser being closed
by a cap or cover easily removable, and forming a junction or union adapted to
receive the burner, the whole being for the purpose of insuring uniformity in
the gas pressure, and to enable a large economy or saving in the consumption to
be effected, substantially as herein before described and illustrated in the accom-
panying drawing.
