Improvements relating to Duplex and other Gas Burners and to
Fittings connected therewith.
I, JAMES LOVE, of 1 Millias Terrace, Leyton Road, Stratford in the County
of Essex, Engineer, do hereby declare the nature of this invention to be as
follows:-
My invention relates to fittings for duplex and other gas burners and comprises
the improvements hereinafter set forth.
An important feature of my said invention consists in the provision of improved
means for enabling a gas burner to be employed either as a duplex or as a single
burner as may be desired.
Another feature of my said invention is the provision of suitable means for
permitting the gas supply to one of the lights in a duplex burner to be completely
cut off and the light extinguished whilst the gas supply to the other burner is
partially cut off so that the said light is turned down very low, and forms a pilot
light, that is to say only gives sufficient light to indicate the whereabouts of the
said gas burner, and to relight the other or second burner when the gas supply is
again turned on thereto.
My improvements are also advantageously applicable to burners with three or
other convenient number of lights.
In carrying my said invention into practice I provide a socket or body having
two short arms or branches provided with internally screw-threaded holes adapted
to receive the externally screw threaded extremities of the burners. The said arms
and holes are so arranged that the burners will have a suitable inclination towards
each other. The main or central portion of the said body or socket is bored out
taper and communicates with the holes in the said arms through suitable ports or
ways. In this taper hole is fitted a correspondingly tapered plug having a central
hole or recess and three ports or ways. These ports or ways are so arranged
that when the said body or socket is turned or adjusted upon the said plug in one
direction the said central hole or recess will communicate with the burners through
two of the said ports or ways and the corresponding ports or ways in the body or
socket, and when turned or adjusted in a direction either to the right or left of
this position two of the said ports or ways will be sealed or closed, and the said
central hole or recess will communicate with one or the other of the said burners
through the third or remaining port or way and the corresponding port or way in
the said body or socket. The taper plug is retained in position in the said corre-
sponding taper hole or recess in the body or socket by means of a screw and washer
or in any other convenient manner. I provide moreover upon the said taper plug
a pin stud or projection adapted to engage with a shoulder at either extremity of a
slot, groove, or recess in the main portion of the body or socket. When the body
or socket is so moved or adjusted that this pin stud or projection is in the centre or
approximately in the centre of the said slot, groove, or recess two of the ports
or ways in the said taper plug will correspond with the two ports or ways in the body
or socket. When the said body or socket is so adjusted that the said pin, stud or
projection is engaged with the shoulder at one extremity of the said slot, groove, or
recess two of the said ports or ways will be sealed or closed, and the third or
remaining port or way will correspond with one of the ports or ways in the body
or socket, and when so adjusted or moved as to engage with the shoulder at the
other extremity of the said slot, groove, or recess one of the said ports or ways will
correspond with the other port or way in the said body or socket.
I sometimes so arrange the said slot groove, or recess that when the above

page_text: mentioned pin is in engagement with the shoulder at either extremity thereof
the said port or way in the taper plug will only partly correspond with the
port or way in the body or socket, and only a sufficient supply of gas be
admitted to the burner to produce a pilot light, that is to say a sufficient
light to indicate the whereabouts of the burner, and to permit the relighting
of the other burner therefrom when the body or socket is readjusted for that
purpose.
The lower extremity of the said taper plug is internally screw threaded to
screw upon the free extremity of a bracket or other fitting or to receive a suitable
thimble or nipple adapted to screw into a suitable socket upon the feed extremity of
the said bracket or other fitting or the said lower extremity may be externally
screw-threaded for the like purpose.
The gallery or bracket for supporting the globe shade or the like may be screwed
upon the said lower screw threaded extremity of the taper plug, or upon the said
thimble or nipple, or otherwise secured thereto. I prefer however to attach it by
means of lugs and screws, by screwing it thereon, or in any other convenient manner
to the herein before mentioned body or socket, thereby enabling the said body or
socket to be very conveniently moved or adjusted upon the taper plug by means of
the said gallery or bracket.
As for
A burner fitted with my improvements is very advantageous in situations where
it may be desirable to double the amount of light at a moment's notice.
instance when the gas employed is carburetted or enriched, should a failure or
break down of the carburetting apparatus take place. And in workshops and other
places where it is desirable for the sake of economy that a workman should turn
down his light as low as possible without extinguishing it during temporary absence
or the like.
In the latter case it would be advantageous to so arrange the herein-
before mentioned ports or ways that when the body or socket is adjusted upon the
tapered plug so as to bring the pin, stud or projection in the centre or approximately
in the centre of the said slot groove, or recess, a full supply of gas would be
admitted to both burners, when adjusted so as to engage with the shoulder at one
extremity of the said slot groove or recess a full supply of gas would be
admitted to one burner only and the supply entirely cut off from the other, and
when adjusted so as to engage with the shoulder at the other extremity of the
said slot, groove or recess only a partial supply of gas would be admitted to
one of the said burners, and the supply entirely cut off from the other. Thus
enabling the user to obtain a duplex, single or pilot light as may be desirable and
convenient.
Although I have hereinbefore described my invention as applied to a duplex burner
that is to say to a burner having two lights, it will be readily understood that by
obvious modifications it is also advantageously applicable to burners having three
or other suitable number of lights.

COMPLETE SPECIFICATION.
Improvements relating to Duplex and other Gasburners and to
Fittings connected therewith.
I, JAMES LOVE, of 1, Millias Terrace, Leyton Road, Stratford, in the County
of Essex, 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 :—
My invention relates to duplex and other gas-burners and comprises the improve-
ments hereinafter set forth.

page_text: The main object of my said invention is to provide in a simple and efficient
manner for the adjustment of a duplex or other multiple gas-burner so that the
same can be caused to furnish either a single flame or two or more flames as may
be desired.
By my present improvements, moreover, I am enabled to provide for the adjust-
ment of a duplex or other multiple gas-burner in such a manner that the gas-supply
to one section or burner can at any time be partially cut off and the gas supply to
the other burner or burners at the same time completely cut off, so that the light is
turned down very low, and forms a pilot light, that is to say, only gives sufficient
light to indicate the whereabouts of the gas-burner, and to relight the gas from the
other burner or burners when the supply is again turned on or admitted thereto.
In the accompanying drawing I have shown how my said invention may be
conveniently and advantageously carried into practice.
Figure 1 is a vertical section illustrating an application of my improvements to a
duplex gas-burner.
Figure 2 is a similar view to Figure 1 showing the parts in a different position.
Figure 3 is a side elevation showing a method of securing a gallery or bracket
for supporting a globe thereto.
Like letters indicate corresponding parts throughout the drawing.
A is a socket or body having two short arms or branches A', A' which are
internally screw-threaded to receive the externally screw-threaded extremities of
burners B which may be of any well known or ordinary construction. The said
arms A1, A2 are preferably so arranged that the burners B are inclined towards
each other. The main or central portion of the said body or socket is bored out
taper and communicates with the holes in the said arms through suitable ports or
ways A', A. In this taper hole is fitted a correspondingly tapered plug Chaving
a central hole or recess C¹ and three ports or ways C2, C3, C4 communicating there-
with. The ports C2, C₁ are in line with each other, and the port C³ is at right
angles thereto. The taper plug C is retained in position in the body or socket A
by means of a screw and washer or in any other well-known or convenient manner.
D is a pin, stud, projection or stop adapted to engage with a shoulder at either
extremity of a slot, groove or recess A formed in the main portion of the body or
socket A. The pin, stud or projection D is preferably so arranged relatively to
the ports or ways C2, C3, C4 that, when the body or socket A is turned or adjusted
upon the said plug in one direction or so that the said pin, stud or stop D is the
centre or approximately in the centre of the slot, groove or recess A, the ports or
ways C, C will correspond with the ports or ways A4, A5 (as shown in Figure 1)
and gas will be supplied to both the burners B; but when the said body or socket
is turned or adjusted in a direction either to the right or left of this position so as
to bring the pin, stud or stop D against the shoulder or abutment at one or other
extremity of the said slot, groove or recess A, the said ports or ways C³, C* will
be sealed or closed, and the port or way C³ will correspond either with the port or
way A (as shown in Figure 2) or with the port or way A³, and gas will be supplied
to only one of the burners B. E is a short lever or handle firmly secured to or
formed on the body or socket A to facilitate the turning or adjustment thereof.
I sometimes so arrange the said slot, groove or recess A that, when the pin, stud,
projection or stop D is at one end thereof and in engagement with one of the
shoulders or abutments, the port or way C³ will only partly correspond with the
port or way A or A' as the case may be, and consequently only a sufficient supply
of gas will be admitted to the corresponding burner B to produce a pilot-light, that
is to say, a sufficient light to indicate the whereabouts of the burner, and to permit
the relighting of the other burner therefrom when the body or socket A is readjusted
for that purpose.
The lower extremity of the said taper plug is internally screw-threaded as shown
to fit upon the free extremity of a bracket or other fitting or to receive a suitable
thimble or nipple adapted to screw into a suitable socket upon the free extremity

page_text: of the said bracket or other fitting, or the said lower extremity may be externally
screw-threaded for the like purpose.
In Figure 3 I have shown my improved burner provided with a gallery or
bracket for supporting a globe, shade or the like. The said gallery or bracket F
is secured to the socket A by means of screws as shown (in which case the lever or
handle E may be dispensed with), or it may be screwed upon the taper plug C, or
otherwise secured thereto. When the gallery or bracket is secured to the body
or socket A, it can be used for adjusting the latter upon the taper plug.
My improved burner is very advantageous in situations where it may be desirable
to increase the amount of light at a moment's notice, for instance where the gas
employed is carburetted or enriched, and a failure or break down of the carburetting
apparatus takes place, or in workshops and other places where it is desirable for the
sake of economy that a workman should turn down his light as low as possible
without extinguishing it, during temporary absence or the like. In the latter case,
I find it advantageous to so arrange the slot, groove or recess that, when the pin,
stud or stop is adjusted so as to engage with the shoulder or abutment at one
extremity of the said slot, groove or recess, only a partial supply of gas will be
admitted to one of the said burners, and the supply entirely cut off from the other,
thus enabling the user to obtain a pilot-light as hercinbefore mentioned.
It is obvious that my said invention is also advantageously applicable to burners
having three or any other suitable number of lights.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what 1
claim is :-
First. A duplex or other multiple gas-burner in which the part or socket wherein
the burners proper are secured, is adjustable about a suitable axis to regulate or
control the supply of gas to the said burners, substantially as hereinbefore described
and for the purposes specified.
Second. The improved apparatus consisting of the parts constructed and combined
substantially as described with reference to the accompanying drawing and operating
as, and for the purposes, above specified.
