PROVISIONAL SPECIFICATION.
An Improved Gas-burner.
We, WILLIAM TULLY, of 58 Gurney Road, Leytonstone, in the County of
Essex, Engineer, and JOHN CORBETT, of Newhaven, Burghill Road, Sydenham,
in the County of Kent, Engineer, do hereby declare the nature of this invention to
be as follows:-
Our invention relates to an improved argand gas-burner of the kind or class
described in the Specification of former Letters Patent No. 10,675 dated 20th
August 1886, in which there is a lower chamber or reservoir connected with a
perforated annular chamber or argand ring by a series of hollow pillars or tubes.
Heretofore these burners have been built up of a large number of parts fitted
together and secured by screw-threads or otherwise; consequently the cost of
manufacture of such burners has been very great. Morcover, by reason of the
large number of joints required in such burners, great care must be taken in their
manufacture in order to ensure tightness of the said joints and prevent leakage.
Now our invention is chiefly designed to simplify the construction of such burners
and to avoid or diminish the liability to leakage of the gas therefrom. For these
purposes, we greatly reduce the number of parts of which the burner is composed,
and we dispense with joints in that part of the burner through which the gas flows,
with the exception of the joint between the annular metal chamber of the burner
and the perforated ring of steatite or other refractory material, when such a
refractory ring is used.
Our improved argand burner is constructed as follows, that is to say :-
:-The
lower chamber or reservoir of the burner, the annular chamber or argand ring, or
the metallic portion of the same, and the pillars connecting these parts are cast in
one piece, the metallic part of the annular chamber or argand ring being made
solid, if necessary or desirable, and afterwards bored or turned to form the required
annular chamber or cavity. Suitable holes are bored through the pillars which
connect the annular chamber or argand ring with the lower chamber or reservoir,
so that the said annular chamber or argand ring is in communication with the lower
chamber or reservoir through the said pillars. The socket or taper nipple at the
lower part of the burner is also formed integrally with, the lower chamber or
reservoir. Therefore, in our burner, there are no joints needed in the metallic
portion through which the gas flows, this portion consisting of a single piece of
metal.
There may be any desired number of deflecting cones in our burner. The top or
outermost deflecting cone and the gallery for supporting the chimney are cast in
one piece, thus ensuring great strength and rigidity thereof and obviating the
necessity for forming screw-threads in the gallery and on the exterior of the said
cone for the purpose of securing these parts together, and avoiding the liability to
loss or displacement of the said gallery. This arrangement also prevents the
placing of the chimney on the burner at an improper or unsuitable angle.
We sometimes form in one piece with the annular chamber or argand ring or
with the metal portion of the same, the arms for supporting the deflecting cones.
Moreover we so construct the cones and the arms for supporting the same that the
said cones can be sprung into their places on the said arms, and will then be firmly
retained thereon without the use of rivets or the like.
For holding in place on the gallery, the chimney, globe, cup or shade as the case
may be, we prefer to provide a device comprising a spring bolt or catch which is
arranged in a suitable projection or lug formed for the purpose on the said gallery.
We can, however, use any other convenient device for this purpose.

page_text: Our improved burner may, if desired, be made with more than one ring of holes
for the egress of the gas, or with more than one perforated annular chamber or
argand ring formed entirely of metal or partly of metal and partly of steatite or
other suitable refractory material.
The disc for deflecting the air against the interior of the flame may be secured
in any convenient manner. We sometimes form in one piece with the top of the
reservoir, a stem for supporting this disc, so that the disc may be placed upon the
said stem and the latter clinched or riveted over to retain the disc thereon.
Instead of making the annular chamber or argand ring, the hollow pillars or
tubes, the lower chamber or reservoir and the socket or taper nipple of a single
piece of metal, we sometimes form in one casting the said annular chamber or
argand ring (with or without arms for supporting the deflecting cones), the pillars
and the top of the reservoir, and in another casting the body of the reservoir and
the socket or taper nipple. In this case, we unite the body and top of the reservoir
by means of screw-threads or in any other convenient manner.

SPECIFICATION.
An Improved Gas-burner.
We, WILLIAM TULLY, of 58 Gurney Road, Leytonstone, in the County of
Essex, Engineer, and JOHN CORBETT, of New Haven, Burghill Road, Sydenham,
in the County of Kent, 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 invention relates to an improved gas-burner of the kind or class described in
the Specification of former Letters Patent dated 20th August 1886, No. 10,675, in
which there is a lower chamber or reservoir connected with a perforated annular
chamber or argand ring by a series of hollow pillars or tubes.
Heretofore these burners have been built up of a large number of parts fitted
together and secured by screw-threads or otherwise; consequently the cost of
manufacture of such burners has been very great. Moreover, by reason of the
large number of joints required in such burners, great care must be taken in their
manufacture in order to ensure tightness of the said joints and thus prevent leakage.
Now our invention is chiefly designed to simplify the construction of such burners
and to avoid or diminish the liability to leakage of the gas therefrom. For these
purposes, we greatly reduce the number of parts of which the burner is composed,
and we dispense with joints in those parts of the burner through which the gas
flows, with the exception of the joint between the annular metal chamber of the
burner and the perforated ring of steatite or other refractory material, when such a
refractory ring is used.
In the accompanying drawings, we have shown how our said invention may be
conveniently and advantageously carried into practice.
Figure 1 is a plan,
Figure 2 a side elevation, and
Figure 3 a vertical central section, showing one form of our improved gas-
burner.
Figure 4 is a vertical central section, showing a casting turned and bored to form
the metal portion of the burner proper.
Figure 5 is a plan of the uppermost deflecting-cone detached.
Figure 6'is a plan, and
Figure 7 a side elevation, illustrating another modification of our said invention.
Figure 8 is a vertical central section, and

page_text: Figure 9 a side elevation, showing a further modification of our said invention,
and
Figure 10 is a side elevation, showing a device hereinafter described for retaining
the chimney in place upon the chimney-gallery.
Like letters indicate corresponding parts throughout the drawings.
Referring to Figures 1 to 4, a is a main chamber or reservoir; b b are annular
chambers connected therewith by hollow or tubular pillars or columns c, c'. These
parts are cast in one piece, the parts b, b and c, el being, by preference, made solid
and afterwards turned and bored to form the required annular chambers or cavities,
and the holes for connecting the same with the main chamber or reservoir a through
the said pillars c, c', as shown in Figures 3 and 4. The socket d at the lower end
of the burner, or a taper nipple which may, if desired, be substituted for the said
socket, is also formed integrally with the main chamber or reservoir a. Therefore,
in the improved burner shown in Figures 1 to 4, there are no joints in the metallic
portion through which the gas flows, this portion consisting of a single piece or
casting. This casting is shown more clearly in Figure 4, the only separate parts
shown in this figure, being the regulating screws hereinafter mentioned.
e, e¹ are perforated or argand rings of steatite or other suitable material, which
are secured in any convenient manner in the annular chambers or cavities b, b'.
fff are the deflecting-cones or deflectors, which are supported upon arms,
lugs or brackets g. These arms, lugs or brackets, by preference, form parts of the
aforesaid casting. Two or more of the said deflecting-cones are preferably used
in our improved burner; and we prefer to so construct the said deflecting-cones
and the arms for supporting the same that the said deflecting-cones can be sprung
into their places on the said arms and will then be firmly retained thereon without
the use of rivets or the like. Or the said cones can be retained in place by pins
passed through the same and through the parts of the arms or brackets which
extend upward between the said cones, as shown, for example, in Figure 8. These
pins may be screwed in, or they may be tightly driven in, or, if desired, they may
be secured in place by riveting.
The top or outermost deflecting-cone has formed therewith the gallery h for
supporting the glass chimney, thus ensuring great strength and rigidity of the said
chimney-gallery, and obviating the liability to loss or displacement of the same, and
the necessity for forming screw-threads therein and on the exterior of the said cone
for the purpose of securing these parts together. This arrangement also prevents
the placing of the chimney on the burner at an improper or unsuitable angle.
For holding the chimney in place on the gallery h, we sometimes provide a device
comprising a spring bolt or catch, which is arranged in a suitable projection or
lug ¹ formed for the purpose on the said gallery . We can, however, use any
other convenient device for this purpose.
In the burner illustrated in Figures 1 to 4, the brackets are formed with
extensions g¹ to receive arms or rods for supporting a shade or globe.
Our improved burner may, if desired, be made with a single argand ring or it
may be made with more than two rings of holes for the egress of the gas, or with
more than two perforated annular chambers or argand rings formed entirely of
metal, or partly of metal and partly of steatite or other suitable refractory material.
kis a disc or spreader for deflecting the air against the interior of the flame.
This disc is formed with a stem which is firmly screwed into the top of the
réservoir a. We sometimes form in one piece with the top of the reservoir, a stem
for supporting the disc or spreader, so that the said disc or spreader may be
placed upon this stem and the latter be clinched or rivetted over to retain the said
disc thereon. The said disc may, however, be secured in place in any other
convenient manner.
It has been found in practice that, in burners such as that above described
wherein two or more concentric argand rings are employed, one flame is apt to rise
above another, and such variation in the relative height of the flames cannot
be regulated by means of the supply tap or cock. We therefore provide for

page_text: permitting the adjustment of one flame relatively to another, by the employment
of regulating taps or screws in the hollow pillars or tubes which connect the annular
chambers or argand rings with the aforesaid reservoir.
In the burner shown in Figures 1 to 4, the hollow pillars c are provided with
regulating screws for the purpose above specified. These screws are fitted
tightly into transverse tapped holes in the said pillars or tubes, and a suitable
passage or way is then bored through each of the said screws. By turning these
screws about their axes in one or the other direction, the height of one flame can
be increased or diminished without varying the height of the other flame or flames.
We may, if desired, provide such regulating taps or screws in all of the pillars
which connect the annular chambers with the reservoir.
Instead of making the argand ring or rings, the hollow pillars or tubes, the
reservoir and the socket or taper nipple of a single piece of metal, we sometimes
form in one casting, the said argand ring or rings (with or without the arms for
supporting the deflecting-cones and the globe or shade), the pillars and the top
or cover of the reservoir; and we form in another single casting, the body of the
reservoir and the socket or taper nipple. In this case, we unite the body and top
or cover of the reservoir by means of screw-threads or in any other convenient
manner.
Instead of the lower chamber a, an annular reservoir may be provided which
surrounds the argand ring or rings, and which is connected therewith and with the gas
supply pipe by suitable hollow connecting pieces or tubes, which may if desired be
provided with regulating taps or screws as above described.
In Figures 6 and 7, we have shown a modification of our invention wherein we
form in one piece with the uppermost deflecting-cone or deflector, not only the
chimney-gallery h, but also the lugs or sockets for the reception of the arms
or rods m for supporting a globe or shade. In these figures, moreover, we have
illustrated a novel method of securing these arms or rods. For this purpose, we
provide slotted lugs n, which, in this instance, are formed on the deflecting-conc
and we make the lower ends of the arms or rods m of such shape that they will fit
into the slots in the lugs n, and the two parts of each lug can then be squeezed
together so as to retain the corresponding arm or rod therein. The said arms or
rods m are, moreover, formed with flanges m', which bear against the upper and
under surfaces of the said lugs, so that the said arms or rods are very rigidly
secured in their proper position. We thus obviate liability to twisting of the said
arms or rods.
In Figures 8 and 9, we have shown a modification of our invention wherein we
use, in place of the reservoir a shown in Figures 1 to 4, two pipes or branches a¹
extending from the socket d to the annular chamber b. These pipes a', the
socket and the annular chamber and arms or brackets are all formed of
a single piece of metal, which is first cast and then turned and bored as required
so that no joints exist between the said parts, and there is consequently no liability
to leakage.
In Figure 10, we have shown another device which we find advantageous for
securing the chimney o in place upon the gallery . This device consists of
a small toothed wheel p which is fitted to turn upon an axle p¹ in one of the
arms or brackets of the said gallery. This wheel is so formed that, when the chimney
is placed upon the gallery, it will strike one of the teeth of the said wheel
and partially rotate the said wheel, so that the next succeeding tooth thercof will
retain the chimney in place. One or more of these toothed wheels may be
employed as may be found most advantageous.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed we wish it understood
that we claim
