For the Applicant.
I, JEAN LOUIS DURONT, of 55 Rue Planchat, Paris, Plumber and Gas Fitter,
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 :-
My invention relates to improvements in regulators for gas water and other
fluids.
1
In applying my invention to the regulation of gas employ a disc or ring of
some compressible material such as india rubber, through the disc being an opening
or openings, or it may be solid on either side of the disc are plates of metal or hard
material of a saucer or similar shape also having an opening or openings through
them the edges of such plates bearing on the compressible disc so that when the
plates and discs are under pressure the opening or openings in the latter will be
reduced in diameter and rice versa or the disc will be expanded to close an orifice.
These parts are arranged in a casing formed in portions screwed together so that
the disc may be compressed and the size of the opening or openings before

page_text: referred to if employed be regulated, the easing being provided with a suitable
inlet and outlet and with means for adjusting the parts such as a handle.
When
used for gas the casing or chamber may contain cotton wool or some material
which will clense the gas in its passage through it, and where a small jet is
required a bye pass may be employed in the shape of a small tube which passes
through the opening or openings in the dise and plates and communicates with the
inlet and outlet.
The invention will be best understood by reference to the accompanying
drawings illustrating a number of instances in which this improved feed regulator
may be applied or taken advantage of.
Figs. 1 to 3 refer to a gas supply regulator.
Fig. is an external elevation of a complete regulating device constructed in
nccordance with this invention.
Fig. 2 a vertical section thereof, and
Fig. 3 detail views showing the elastic disc and compressing plates or sameers
detached.
Fig. 4 shows the employment of the improved regulator in connection with a
burner having a basket-shaped cage or gallery placed round it, it being partly
a vertical section and partly an elevation of a sell regulating gas burner of this
cla-s.
Figs. 5, 6 and 7 illustrate methods of applying my invention to the nozzles of
watering hose.
Fig. 5 is a vertical section of a nozzle with the orifice open, and
Figs. 6 and 7 views of a modified form of a nozzle, representing it open al
closed, respectively.
Fig. 8 is a sectional elevation illustrating the mode of employment of the
improved regulator in connection with the tap or plug of a wash-hand stand or
similar appliances.
Figs. 9, 10 and 11 illustrate the manner of applying the improved feed regulating
or checking arrangement to the valves of pneumatic tyres,
Fig. 9 is an elevation, drawn on an enlarged scale, of a valve fitted with my
improved device, and with the closing tap detached.
Fig. 10 a vertical section of the valve with a centrally perforated india rubber
washer, open, to enable the tyre tube to be inflated, and
Fig. 11 is a similar section of a valve fitted with a solid india rubber washer.
closed with a cap, as it should be after the inflation of the tyre.
As will be seen by referring to Figs. 1 to 3 of the drawings, this gas supply
regulator consists of a piece a to be secured on to the gas supply pipe inside of
which is a mass of cotton or the like acting as a strainer. Upon the upper part
of this part a rests a disc e of india rubber or any other suitable elastic material
interposed between metal plates or saucers d, each provided with a central orifice e
The washer also has an orifice provided in its centre.
On to the piece a is screwed a sleave y provided with a finger piece or handle/
and serving for the reception of both the discs e nnd plates or saucers d. Upon
this sleeve the burner proper may be fixed.
From the foregoing description it will be seen that when the sleeve g is screwed
(in the required direction) round the plate a by means of the part 4, the elastic
disee will be compressed by the plates or saucers d, with the result that the orifice
of such dise will be correspondingly reduced in sectional area, so as only to adint
to the burner a predetermined quantity of gas, which may be greater or less
according as the sleevey is displaced to a greater or less extent.
As before stated, the gas, before flowing past the disc-orifice, on its way to the
burner, must traverse the mass of cotton or strainer which is adapted to retain
any impurities which the gas may carry with it, the result being that only pure
gas of a correspondingly increased illuminating power will be supplied for
consumption.
If it be desired to provide a byo pass or a small jet which may be kept burning

page_text: a small tube i may be located within the piece a and extend through the cotton /
and through the orifices e and and he supported in any suitable way such as in
the contracted opening a¹ of the part a means being provided to allow the gas to
pass through the disc at the end of such tube.
Fig. 4 represents a gas burner fitted with a feed regulating or controlling device
constructed in accordance with my invention.
In this figure A designates a burner with a cage, gallery or basket surrounding
it, within the gas supply tube or nozzle B of which there is screwed a gas regulator
of this improved construction, from which, however, the piece shown in Figs. 1
aud 2 is omitted, the basket or gallery D of the burner covering the whole of the
upper sleeve C of the regulator. The lower part E of the regulator, which is
screwed into the said sleeve C, is at the same time screwed at F. for attachment to
pipe in the usual way. This burner, (which in the drawing is shown supplied
with a bye pass i) is controlled as above described in reference to the general
construction of the regulator, by the compression of the india rubber disc.
The advantages of this burner are that the regulator is enclosed within the cage
or gallery of the burner, so that while space is saved, the appearance of the
arrangement is improved. Furthermore, the gas supply may be turned on to the
full extent without any danger, since the maximum supply is limited by the check
device; or a plug or tap may be entirely dispensed with if desired.
As will be seen from Fig. 5 which illustrates the method of application of my
regulating device to the nozzle of water pipes or hose, such as B, a screw threaded
tube A, is here employed, some of the convolutious of the screw thread being
flattened down or cut away so as to leave around the tube an annular recess or
space of less diameter, whereon is placed a plate or saucer E, of brass or any other
suitable metal, equal in diameter to the threaded tube and having its convex
portion turned outwardly. In this plate or saucer there is provided a central
aperture e, and upon it is placed the elastic disc F of the same diameter and of
sufficient thickness or depth, and having also a central aperture aty. Upon this
disc there is placed, with the convex or raised portion outwards, a second
cup E, similar to the cup E, and having an aperture el, similar to e, provided in its
centre.
The outer surface of the tapped sleeve C may be milled, fluted or otherwise
roughened so as to facilitate the grasping of it, and at its end it is provided with a
It will be
central aperture D. It is screwed on to the threaded portion A.
understood that, by screwing, the disc F may be compressed, whereby the sectional
area of its central aperture will be reduced; it being, in fact, reducible to the
extent of closing the outlet orifice altogether; an arrangement which enables the
supply of water or other liquid to be reduced to the desired extent, or stopped
completely, by a single operation or movement of the hand.
In the arrangement for water pipe or hose nozzles as above described, an elastic
disc perforated in the centre, and two hollow metal plates or saucers are used; the
conen ve sides of the latter being placed next to the disc, and their centres being
correspondingly perforated. Now in the modification represented in Figs. 6 and 7,
there is substituted for the centrally perforated disc, a solid disc of the same or
equivalent material, such as F, the diameter of which is less than the annular
space or orifice F, which it is adapted to close when compressed between two
metal plates or saucers EE, as illustrated in Fig. 7, such cups being here arranged
inversely in relation to each other, namely so that their convex faces are adjacent
to the disc. In each of these plates there are provided, in the vicinity of their
periphery, two or more small apertures or ports the aggregate sectional area of
which should be at least equal to the sectional area of the central aperture provided
in each of the plates before described.
It will be readily understood by inspecting Figs. 6 and 7 that when the parts of
the arrangement occupy the positions in which they are shown in Fig. 6, the
water or other fluid supplied through A will pass freely through the apertures or
ports ee of the plates or saucers into the space F which is at that moment left

page_text: around the solid dise F. Hence it will pass through the orifices or ports of
the plate or saucer E' and into the nozzle proper I from which it is discharge 1.
When the disc F, is compressed as illustrated in Fig. 7, the annular passage F
shown in Fig. 6 will be entirely obstructed and will therefore intercept the flow
of water or other liquid.
In the wash-hand stand arrangement shown in Fig. 8 the water through B,
passes through the central perforations Deƒ and el, then through the tubular
threaded plug A (screwed into the tapped sleeve or bush (,) and issues through
the tube or nozzle II of the latter.
It will he understood that the maximum supply in taps of this description may
be readily adjusted by any convenient checking medium. Thus, in some cases, the
perforation in the einstie dise F may be arranged to surround a central spindle or
rod of less dinmeter so as to form an annular passage for the water or fluid, which
will be found a particularly advantageous arrangement wherever large quantities of
water or the like are to be supplied.
Fig. 9, 10 and 11 illustrate the mode of employment of this improved checking
er feed regulating device in conjunction with pneumatic tyre valve.
In these figures A designates the body of the valve provided with two screw
threads a ' and with the usual head a². B Bare, respectively, the washer and
tightening nut. C is the counter nut for the cap D provided with a safety chain E.
The nuts B and C are screwed upon the screw thread a, whilst the cap D, (and
when the latter is removed the branch pipe making the connection with the pump
employed in inflating the tyre) are screwed on to the screw thread a' as shown in
the drawings.
F is a metal plunger, with a top part or head on which there may he provided,
if desired, grooves or flutings, such as are shown at . Figs. 10 and 11, and
which bears on the lower metal plate or saucer H, which is either convex and
provided with a central perforation (Fig. 10), or concave and perforated at two
or more points near the periphery (nº at 4 h Fig. 11). I is the elastic disc, either
centrally perforated as shown in Fig. 10, or solid as shown in Fig. 11, and His
the opposite convex metal plate or saucer, having a central perforation A', as shown
in Fig. 9, or being concave and provided with two or more peripheral perforations
as shown in Fig. 11, such plate or saucer bearing on a screw K, through the central
aperture of which air is admitted into the pneumatic tyre.
It will be understood that as soon as the length of tube making the connection
with the pump is screwed on to the screw thread a', the air supplied by the pump
will enter the pneumatic tyre through the space around the head of the
plunger F, passing them through the port or ports of the plate or saucer,
through the central perforation of the disc 1 (as shown in Fig. 10), and lastly
through the port or ports of the opposite plate or saucer and through the
central orifice of the screw-threaded plug K; the pressure of the air, in the
intervals between the successive strokes of the pump foreing the head of
the plunger down upon its seat, which may, or may not, he lined with leather,
indin rubber or any other suitable joint closing or packing material.
As soon as the inflation of the tyre is completed, the cap D should be screwed on
to the screw thread a' and, as this is done, the elastic disc I will be so compressed as
to completely close the valve and effectually prevent any escape of the air confined
in the pneumatic tyre or tube.
Having now particularly described and ascertained the nature of my said inven
tion and in what minuer the same is to be performed I declare that what I
claim is :-
1. In a regulating device for gas, water and other fluids, the combination with a
compressible disc adapted to allow the fluid to pass same, of plates or saucer
shaped pieces of hard material having openings therein substantially as and for the
purpose described.
2. lu a regulating device for gas, water and other fluids, a perforated

page_text: compressible disc held between two perforated plates or saucer shaped pieces
substantially as and for the purpose described.
3. The employment with the parts described in the preceding claims of a
suitable casing for holding same and an adjustable part adapted to determine
the amount of compression of the disc substantially as and for the purpose
described.
4. The improvements in regulators for gas water and other fluids substantially
as described and illustrated in the accompanying drawings.
