We ROUGHSEDGE WALLWORK of the firm of Henry Wallwork & Co., of Union
Bridge Iron Works, Manchester, in the County of Lancaster, Iron Founders, and
ARTHUR COLLINGS WELLS, of Ogden Street, Manchester, aforesaid, Engineer, do
hereby declare the nature of the said invention to be as follows:-
Our improvements are made upon those for which Letters Patent were granted to
the said Roughsedge Wallwork Numbered 15,328 A.D. 1886, and also upon the
improvements described in a complete specification filed in accordance with an appli-
cation for Letters Patent Numbered 3543-1887 in the names of the present applicants,
and our present improvements consists in improved combinations and arrangements
of parts.
We prefer to arrange the burners described in the Specifications of the above named
Patent and application for a Patent, when in use for giving light with the axis of the
burner in a horizontal position, that is, so that the flame from the burner will pass
from it horizontally and in the direction of the wind, and we mount the burner upon
a swivel secured on the oil supply tube so that it can be turned round in a horizontal
plane in any required position to suit the direction of the wind when used in the
open air, and when so arranged we use or may use a shield on the oil supply pipe or
base of the burner to shield the flame of the burner from the action of the wind.
We also use in some cases a wind vane connected with the burner to cause the
burner to turn on its swivel to suit each change in the direction of the wind, and thus
keep the burner and its shield so as to protect the flame from the wind.
We sometimes use adjustable and movable shields or covers to protect the light or
conceal it in certain directions and when required at certain intervals when used for
signalling or other purposes.
Another improvement consists in making the supply pipe telescopic so as to be able
to elevate the light to any required distance above the ground and shut up the telescopic
oil supply tube when required.

page_text: There are screws or other arrangements at each length of the telescopic oil supply
tube to secure it when out or in, and there is a cock to allow oil to pass from the
tube to the oil cistern or reservoir when the tubes are pushed inwards while the
burner is in use.
Another improvement for lighting the burner consists of a hollow .cone of metal,
this cone is placed over the burner and has waste fibrous or other suitablo material
placed within it which is ignited and burned to heat the gas or vapour generating
tubes of the burner, and when sufficiently heated the ignited and heating cone is
removed and the gas or vapour from the burner will then burn by itself and generate
its own supply of gas or vapour and eject the same with such pressure through the
air cone as to draw in the air required for the proper combustion of the gas or
vapour.
In our improved arrangement of self generating gas or vapour burner it is not
necessary that the generating tubes shall be entirely surrounded and enveloped by the
flame from the burner, they are or may be partly heated directly by contact with the
flame and partly by radiant heat from the flame, or in some cases the generating
tubes are or may be arranged to be heated entirely by the radiant heat of the flame.
There are cheap kinds of oil or combustible. liquids which are impure, and the
object of our improved construction and arrangement of burner hereinafter described
is to arrange a construction of burner (adapted to burn such and other combustible
liquids) in which the passages to the burner are not so liable to become obstructed by
the impurities in the combustible liquid, and so that the passages of the burner can
also be readily cleared from deposit and other obstructions to the flow of the gas or
vapour.
In our improved burners the tubes for generating the gas or vapour from the
combustible liquid, are arranged by preference as hereinbefore described, in respect
of position, that is, so that the flame will pass horizontally from the burner and under
the generating tubes, by preference, or in such position as to act upon the generating
tubes with the greatest heating effect.
We prefer to use two tubes (but do not confine ourselves to that number) passing
in the direction of the flame and connected at the outer ends by a short cross pipe.
One of these generating pipes comes from the oil supply pipe joins the short cross
tube, then the other starts from the short cross tube and joins a casting in which
passages are formed leading to the burner or jet outlet.
This casting also carries the cone for drawing in air to supply the flame and has a
projection or eye for the first named generating pipe to pass through.
There are screw plugs at the end of each passage so that a drill or other tool may
be readily inserted to clear out deposit or obstruction.
The jet outlet or burner orifice at which the gas or vapour escapes to supply the
flame is formed at one end of a tube, or the jet outlet is or may be.in a separate
piece screwed or otherwise secured in the end of the said last named tube.
The sides of this said last named tube are perforated with numerous small holes a
little less than the orifice for the jet, so that all matters that will pass through any one
of these numerous small holes will also pass through the jet orifice.
The tube for the jet orifice is screwed into a cavity in the said casting which leaves
an annular space round the exterior of the tube with the numerous small holes,
and this cavity is in communication with the generating pipes supplying the gas or
vapour.
In place of numerous small holes in the sides of the jet pipe, it may be made with
a wire gauze exterior, so that the gas or vapour will have to pass from the gauze
before it escapes at the jet orifice.
There is a small hole formed in the casting to allow a very small jet of gas or
vapour to escape from the passage in it in a direction across the main jet discharged
to support the flame, this small jet thus burns at the same time as the main flame and
acts to re-light it in case it happens to go out from any cause.
That end of the generating pipe which is connected with the oil supply pipe is at a
right angle to the generating pipe and is formed to enter a stuffing box socket in the

page_text: upper end of the oil supply pipe and turn round therein easily when the packing is
screwed up tight enough to prevent an escape of combustible liquid passing to the
burner. This pipe, and with it the burner, can be easily withdrawn from and replaced
in the stuffing box socket, so that when the burner is to be lighted it may be taken
and placed upon a fire to heat the generating pipes sufficiently to generate gas or
vapour, then the burner is fixed on the supply pipe and the vapour or gas arising
from the oil forced through is ignited when sufficient heat is obtained from the flame
to keep the generating tubes heated to the point required.
But in place of this mode of starting the burner to work to supply light, that
hereinbefore described may be used.
The impurities in the combustible liquid accumulate in and fill up the valve
passages, and our improvements also consist in arranging so that the combustiblo
liquid will have to pass through wire gauze before it can get to and pass the
cock or valve, this wire gauze being secured to a tube or spindle which can be
readily screwed out and the wire gauze washed or cleaned to remove the dirt and
then screwed in to its place again.
In some cases we use two jet orifices in place of one so that if one becomes
obstructed the other remains operative.
We combine one self generating gas or vapour burners with any of the arrange-
ments for supplying oil or combustible liquids to them described in the specifications
hereinbefore referred to, or those described in the Provisional Specification filed by us
in application for a Patent No. 15,373, A.D. 1887.

page_text: Improvements in Self Generating Oil, Gas, or Vapour Burners, and
in Arrangements Connected therewith.
We, ROUGHSEDGE WALLWORK of the firm of Henry Wallwork & Co. of Union
Bridge Iron Works Manchester, in the County of Lancaster Iron Founders, and
ARTHUR COLLINGS WELLS, late of Ogden Street, now of Carnarvon Street, Manchester
aforesaid, Engineer 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:-
Our improvements are made upon those for which Letters Patent were granted to
the said Roughsedge Wallwork Numbered 15,328 A.D. 1886, and also upon the
improvements described in a complete specification filed in accordance with an
application for Letters Patent Numbered 3543-1887 in the names of the present
Applicants and our present improvements consist in improved combinations and
arrangements of parts.
We prefer to arrange the burners described in the specifications of the above named
Patent and Application for a Patent when in use for giving light with the axis of the
jet of the burner in a horizontal position (or nearly so) that is, so that the flame from
the burner will pass from it horizontally and in the direction of the wind, and we
mount the burner upon a swivel secured on the oil supply tube so that it can be
turned round in a horizontal plane in any required position to suit the direction of
the wind when used in the open air and when so arranged we use or may use a
shield on the oil supply pipe or base of the burner to shield the flame of the burner
from the action of the wind.
We also use in some cases a wind vane connected with the burner to cause the
burner to turn on its swivel to suit each change in the direction of the wind, and thus
keep the burner and its shield so as to protect the flame from the wind.
We sometimes use adjustable and movable shields or covers to protect the light or
conceal it in certain directions, and when required at certain intervals, when used
for signalling or other purposes.
Another improvement consists in making the supply pipe telescopic as as to be
able to elevate the light to any required distance above the ground and shut up the
telescopic oil supply tube when required.
There are screws or other arrangements at each length of the telescopic oil
supply tube to secure it when out or in, and there is a cock to allow oil to pass from
the tube when the tubes are pushed inwards while the burner is in use.
Another improvement for lighting the burner consists of a hollow cone of metal,
this cone is placed over the burner and has waste fibrous or other suitable material
placed within it which is ignited and burned to heat the gas or vapour generating
tubes of the burner and when sufficiently heated the igniting and heating cone is
removed and the gas or vapour from the burner will then burn by itself and generate
its own supply of gas or vapour and eject the same with such pressure through the
air cone as to draw in the air required for the proper combustion of the gas or
vapour.

page_text: In our improved arrangement of self generating gas or vapour burner it is not
necessary that the generating tubes shall be entirely surrounded and enveloped by the
flame from the burner they are or may be partly heated directly by contact with the
flame and partly by radiant heat from the flame or in some cases the generating tubes
are or may be arranged to be heated entirely by the radiant heat of the flame.
There are cheap kinds of oil or combustible liquids which are impure, and the
object of our improved construction and arrangement of burner hereinafter described
is to arrange a construction of burner (adapted to burn such and other combustible
liquids) in which the passages to the burners are not so liable to become obstructed
by the impurities in the combustible liquid and so that the passages of the burner can
also be readily cleared from deposit and other obstructions to the flow of the gas or
vapour.
In our improved burners the tubes for generating the gas or vapour from the
combustible liquid are arranged by preference as hereinbefore described in respect of
position, that is, so that the flame will pass horizontally from the burner and under
the generating tubes by preference or in such position as to act upon the generating
tubes with the greatest heating effect.
We prefer to use two tubes (but do not confine ourselves to that number) passing
in the direction of the flame and connected at the outer ends by a short cross pipe.
One of these generating pipes comes from the oil supply pipe joins the short cross
tube then the other starts from the short cross tube and joins a casting in which
passages are formed leading to the burner or jet outlet.
This casting also carries the cone for drawing in air, to supply the flame and has a
projection or eye for the first named generating pipe to pass through.
There are screw plugs at the end of each passage so that a drill or other tool may
be readily inserted to clear out deposit or obstruction.
The jet outlet or burner orifice at which the gas or vapour escapes to supply the
flame is formed at one end of a tube or the jet outlet is or may be in a separate
piece screwed or otherwise secured, in the end of the said last named tube.
The sides of this said last named tube are perforated with numerous small holes
a little less than the orifice for the jet so that all matters that will pass through any.
one of these numerous small holes will also pass through the jet orifice.
The tube for the jet. orifice is screwed into a cavity in the said casting which leaves
an annular space, round the exterior of the tube with the numerous small holes and
this cavity is in communication with the generating pipes supplying the gas or
vapour.
In place of numerous small holes in the side of the jet pipe it may be made with
a wire guaze exterior or interior so that the gas or vapour will have to pass through
the gauze before it escapes at the jet orifice.
There is a small hole formed in the casting to allow a very small jet of gas or
vapour to escape from the passage in it in a direction across the main jet discharged
to support the flame this small jet thus burns at the same time as the main flame
and acts to relight it in case it happens to go out from any cause.
That end of the generating pipe which is connected with the oil supply pipe is at a
right angle to the generating pipe and is formed to enter a stuffing box socket in the
upper end of the oil supply pipe and turn round therein easily when the packing is
screwed up tight enough to prevent an escape of combustible liquid passing to the
burner-This pipe and with it the burner can be easily withdrawn from and replaced
in the stuffing box socket so that when the burner is to be lighted it may be
taken and placed upon a fire to heat the generating pipes sufficiently to generate
gas or vapour then the burner is fixed on the supply pipe and the vapour or gas
arising from the oil forced through is ignited when sufficient heat is obtained from
the flame to keep the generating tubes heated to the point required. But in place
of this mode of starting the burner to work to supply light that herein before
described may be used.
The impurities in the combustible liquid accumulate and fill up the valve passages
and our improvements also consist in arranging so that the combustible liquid will

page_text: have to pass through wire guaze before it can get to and pass the cock or valve this
wire guaze being secured to a tube or spindle which can be readily screwed out and
the wire guaze washed or cleaned to remove the dirt and then screwed into its place
again.
In some cases we use two or more jet orifices in place of one, so that if one becomes
obstructed the other remains operative.
We combine our self generating gas or vapour burners with any of the arrange-
ments for supplying oil or combustible liquids to them described in the specifications
herein before referred to or those described in the Complete Specification filed by us in
application for a Patent No. 15,373 A.D. 1887.

Fig. 19 is a side sectional elevation and fig. 20 a cross section on the line A-A

We will first describe our improvements in the burner of which a side elevation is
shown, as when in use by fig. 1, and an enlarged sectional elevation by fig. 2, and a
plan and end elevation by figs. 3 and 4.
There is a short longth of vertical tube ƒ which then bends to nearly a horizontal
position its end screwing fluid tight into a casting from which the pipe continues
to a casting or coupling in which there is a passage at a right angle to the pipe f
this casting having one end of another pipe f³ screwed fluid tight into it the other
end of which screws into the said casting which has a passage in a line with the
pipe (see fig. 3) and a cross passage at a right angle to the passage f, and then a
chamber the axis of which is parallel to the passage f*.
It will be seen that there are screw plugs, and in the casting or coupling f
and also screw plugs f8, fo and fx in the casting f¹ and these screw plugs are to close
the ends of passages fluid tight, to which the screw plugs, which when removed give
access for cleaning out any deposit that may accumulate therein.
The nozzle outlet g for the gas or vapour is formed in a tube g¹ which is open at one
end and screws into the casting f" as shown best in fig. 2.
Three modifications of these tube nozzles g' are shown detached and on an enlarged
scale by figs. 10 and 11 and 12 and 13.
That which is shown applied in fig. 2 is represented on an enlarged scale by fig. 10.-
It is screwed at one end to screw into the casting f¹, and the other end is open, and its

page_text: sides are perforated with numerous small holes g² of less area than the outlet orifice g,
so that any lump or particle that will pass any one of the small holes g² will pass the
outlet orifice g.
When the tube gl is screwed into the casting, and the screw plug fx is removed
the interior of the tube gl can be readily cleared of all obstructions and when the
tube g¹ is screwed out the small holes g2 can also be cleared. When the screw plug fx
is screwed in, as shown in fig. 2 the end of the tube g¹ enters the hollow of the screw
plug which acts as a cap to close its end.
The tube g shown by fig. 11 is the same as that shown by fig. 10, except that it has
large holes in its side, and has inside it a piece of wire gauze or wire gauze
tube g*.
The tube g shown by fig. 12, is or may be constructed like fig. 10 or fig. 11, except
that it has more than one outlet orifice y, four being shown in fig. 13, but the total
area of all the orifices g when more than one is used does not exceed the area of the
single orifice I in figs. 10 and 11.
The object of having more than one outlet is to prevent the light from going out
when an outlet orifice is obstructed as would be the case when only one outlet is
employed, but when two or more outlets are used the chance of all being obstructed
at the same time is reduced.
On the casting f¹ a cylinder terminating in a cone his formed and the jet from the
nozzle outlet g, comes into the centre of this cylinder and cone has shown, the open
end of the cylinder towards the orifice g admitting air which is drawn in by the
escaping gas or vapour to supply air for its combustion.
The flame from the ignited gas or vapour, passes under the tubes f and f³ in
front of the cone hand heats these tubes or generators, which converts the com-
bustible oil or liquid into gas or vapour, which passes along the pipe f, across the
coupling along the pipe f³ to the passage in the casting and then to the outlet
orifice g.
The vertical part of the tube fis arranged to enter a stuffing box el in the upper end
of a vertical pipe e from the oil supply cistern (see fig. 2, also fig. 1).
This stuffing box e¹ is formed by a coupling with the pipe e and it has a chamber for
packing material and a screw e² for compressing the packing which screw is rotated by
the handle e-There is or may be a collar e' on the pipe f to rest upon the upper side
of the screw e².
Thus arranged it will be seen that the burner and generating tubes can be
swivelled round in any direction to suit the direction of the wind to keep the
flame as it issues from the cone in a line with and in the same direction as the
wind.
The back of the burner is protected from the wind by a thin sheet metal cover **
shown in dotted line in figs. 1 and 2 and in plan by fig. 5 and in end view by
fig. 6.
There are projections * from the casting to carry a joint pin to which the
cover is hinged or jointed, which cover is closed on its top and sides but is open on
its underside to admit air to the burner-There is a slot (seen in fig. 6) for the
supply pipe and there is a hole in the top part of the cover for the boss for the
screw plug to pass through, when the cover is in the position shown in dotted line
in fig. 2.
To protect the flame and generating tubes from rain or snow and at other times
when required, a cover i¹ is or may be used also hinged at one end to the joint pin
as shown in figs. 1, 2, 5 and 6. This cover is or may be of the shape shown best in
figs. 5 and 6. It has a stud 3 rivetted in it at one end (see figs. 2 and 3) the
lower end of which rests upon the coupling f2 when acting as a cover in the
position shown in fig 2.
This cover when required can be turned back on its hinge 22 into the position
shown in dotted line in fig. 1.
When the burner is to be automatically moved to keep in the direction of the wind
as it changes, a wind vane is or may be used as illustrated by figs. 1 and 7. In this

page_text: case a stud is arranged to rise from the casting to carry a pin or projection having
the wind vane j' attached to it. The end of the cover is or may be in this case
slotted to pass on each side of the stud j and rest upon its shoulder, when down in the
position shown in fig. 1.
Figs. 8 and 9 show a plan and end elevation of a double burner which as to each
single burner is the same as that herein before described, and will be readily
understood being marked with the same letters of reference on the same or
similar parts.
The same pipe supplies both burners the casting f branching on both sides. The
covers and (not shown in these figures 8 and 9) are arranged in a manner similar
to those shown by figs. 5 and 6 but larger to cover both burners.
In some cases we form a small jet outlet from the tube f' (seen best in fig. 3) in
front of and to discharge gas or vapour across the jet outlet g as shown in dotted line
by gx fig. 2, the object of this small jet is to relight the main jet y should it
accidentally go out, as the small jet might in such case remain burning.
The burners and generating pipes can be readily withdrawn from the stuffing box e
and taken to a fire to be heated when to be started into operation, but when the
burner is to be heated in the position in which it is to be used, a tubular sheet metal
cover or chimney & with one or two handles a¹ to lift it when heated is applied as shown
by fig. 16, and fig. 16".
Fibrous material saturated with oil is placed inside the cover or chimney and
ignited and this heats up the generating tubes fand 3 until they form gas or vapour
which will ingnite at the outlet orifice when the cover is then removed.
Fig. 14 is a sectional elevation of the air tight cistern for supplying the combustible
liquid to the burner.
This cisterna is charged with oil or combustible liquid leaving a sufficient space in
the upper part of it for air at the required pressure to supply the burner.
There is a pump barrel secured into a part which screws in a part rivetted to
the upper end of the cistern a, this part 6 has a stuffing box formed in it through
which the pump rod 63 slides which is worked up and down by the handle 4-The
lower end of the pump rod 3 has a disc screwed upon it with holes through it or
with notches in its edge, then there is a leather of the shape shown which
fits the interior of the barrel b and can work to and fro between the disc 6 and
another disc 68 also screwed upon the end of the rod ³ this second disc 68 also having
holes through it or notches in its edge.
When the rod 3 ascends the barrel b the leather * comes against the lower disc 68
and leaves open the holes or notches in the upper disc so that the fluid in the barrel
above the disc 6 can pass below it, but on the descent of the rod 63 the leather * then
comes against the disc and closes the holes or notches in it and forces the fluid in
the barrel b, below the disc 6 through the back pressure valve m into the cistern a.
This last named valve m lias its seating on a casting m² screwed on to the end of the
barrel, the casting m¹ having a cross bar m³ secured to it by screws which cross
bar m³ guides the stem of the valve m which is forced with a disc of leather
secured by a screw.
There is a helical spring on the stem macting between the under side of the
valve m and cross bar m³ to close the valve.
One end of a flexible tube c is coupled with a branch the other end of which tube
has a cylinder e covered with wire gauze secured to it, this end of the flexible tube is
placed in the bucket d (shown in dotted line) or other vessel from which the
combustible liquid is drawn by the pump and forced into the cistern. is a cock for
emptying the cistern a when required.
The combustible liquid passes from the cistern a through a pipe e the open lower
end of which extends nearly to the bottom of the cistern a, and its upper end screws
fluid tight into a casting rivetted or otherwise secured to the cistern.
tap
This casting e has on one side a seating for the end of a cone pointed regulating
which passes through a packing gland.

page_text: The opposite side of the casting e is prepared with a seating for the end of a
hollow screw plug e².
The end of the screw plug e when screwed in tight by the wings e* comes close
against its facing and no fluid can pass to the tap outlet except through the hollow
plug which is screw threaded at e (see enlarged detached view fig. 15) and has a
series of large holes in its side covered with wire gauze es.
The fluid can pass up the pipe e to the chamber surrounding the screw plug filter
through the wire gauze es into the hollow of the plug e and then pass through the hole
which can be closed or partly closed as required by the screw plug tape.
With this arrangement it will be seen that both screws e and e' can be readily
removed, and all obstructions cleared away, and then replaced. From the regulating
tape the combustible liquid passes up the tube e which may be of any desired length
to the tube f of the burner.
In some cases the tube e is made of the desired length, and the tube f is made of
corresponding length so that it may be pushed in or drawn out telescopically, and then
secured in any desired position by tightening the packing screw e² fig. 2. If desired
there are or may be more than two lengths of tube telescopically arranged with a
stuffing box junction connecting each length of tube similar to that hereinbefore
described and shown by fig. 2.
There is or may be a tap inserted in the lower part of the tube e above and near the
coupling or casting e fig. 14 to draw off the oil or combustible liquid in the
telescopic pipes when they are to be slided the one into the others.
Figs. 17 and 18 illustrate one method of carrying our invention into effect were a
movable shield is combined with self generating gas or vapour burners for covering
and uncovering the light for signalling purposes.
The casting has a disc k formed upon it the coupling 2 has a stud or
projection secured in it.
A cylinder of sheet metal is formed-which cylinder is lined with sheet asbestos
or other suitable heat resisting material.
One end of the cylinder is attached to a grooved pulley ³ the hole in which
fits on the disc & so as to rotate freely thereon.
The disc closing the other end of the cylinder 2 has a hole in it to rotate freely
upon the stud ki.
One side of the cylinder is cut away so that when it is turned to one side the
opening thus formed exposes the light; but when turned with this open side upwards
as shown in the figures 17 and 18 the flame is not seen and the light does not show
from it as there is a metal cover over the cylinder 2, at a distance from it, which
prevents the passage of light but allows the products of combustion from the flame to
escape between the cylinder and plate kt.
This cover also protects the flame from rain snow or wind and it is carried on a
stand from or secured to the casting f¹ at one end and on a foot at the other
end secured to the projection .
There are two pins and 8 in the grooved pulley k³ which when they come
against the sides of the stand 45 act as a stop to limit the movements of the
cylinder k².
The cylinder is oscillated for signalling by a handle attached to a chain or
other connection k* secured to the groove in the pulley ³ the other end of the chain
(represented by dotted line) having a weight & suspended upon it sufficient to rotate
the cylinder when free to bring the stop k against the side of the stand as shown
in fig. 18 in which position the opening in the cylinder 2 is upwards and the light is
covered by the plate but when the handle is pulled down the cylinder ² is
rotated until the other stop 4 comes against the other side of the stand Z in which
position the opening in the cylinder uncovers the flame-The burner is placed with
that side of the flame which is to be exposed in the direction in which the signal is to
be seen in the distance.
Figs. 19 and 20 illustrate another modification of our invention for signalling.
On a disc formed on the casting f¹ projections l' are formed for the bearings of

page_text: a shalt which passes through a part
secured to one half of a cylindrical shield
the shaft being secured by a set screw to the part 3-There is a shaft 2 on both
sides each carrying one semi-cylindrical shield which when brought together as
shown in the figures 19 and 20 completely enclose the flame.
At one end of the two half shields, there is a short chimney each half shield
having one half or side of the chimney formed upon it-so that when both are
together the chimney is complete and allows the escape from the shields of the
products of combustion from the flame.
The inside of the shields are lined with sheet asbestos or other suitable non
conducting material.
Either shield can be moved to one side so as to expose the flame to view by
turning the handle on the shaft 12 and there is an arm 18 from each shaft the two
arms being connected by a helical spring which thus draws the two half shields
together.
Another modification of this part of our invention consists in enclosing the burner
with a cylindrical or rectangular cover or casing of sheet metal, which may be carried
in a manner similar to the cylinder 2 in figs. 17 and 18.
This casing has a slit or opening at the upper side to allow of the escape of the
products of combustion which slit or opening is covered by a sheet of metal (corre-
sponding to ) with a space between as in figs. 17 and 18.
There is also an opening on one or on both sides of the casing to expose the flame
and these openings are covered by a thin sheet of metal mounted on an arm or lever
to oscillate on a horizontal axis, carried by a projection from the casting f¹ the sheet
of metal on the lever being counterbalanced by a weight which will lift the sheet
against a stop in which position it will cover the light-The sheet of metal is pulled
down by a suitable handle when the light is to be exposed and it is lifted by the
counterbalance weight into the position to cover the light when the handle is
released.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed we declare that what
we claim is.
1. The arrangement of self generating gas or vapour burners so that they can
