JOHN JAMES ROYLE of 27 King St West Manchester in the County of Lancaster
Mechanical Engineer 'IMPROVEMENTS IN SUSPENDED LIGHTS FROM EXISTING
GAS FITTINGS FOR LIGHTING AND HEATING PURPOSES AND IN BURNERS FOR THE
SAME AND FOR OTHER PURPOSES
"
This Invention relates to Improvements upon an Invention for which Letters
Patent No 5446 were granted to me on the 13th day of December 1881 and has for
its object first to produce a steadier and stronger light and to render the apparatus
applicable to positions where the pressure of gas is low and insufficient to produce
a steady light and also to render the same capable of folding up or occupying less
room for the purpose of packing or carriage from place to place.
In carrying out this part of my Invention I employ an argand burner surrounded
by a glass chimney or globe and which is substituted for the ordinary burner which
in accordance with the specification of my former patent I used as the suspended
light. In order to supply this argand burner I either take the gas down the tubes
which form the support for the shade and which tubes are gathered into a single
tube which passes up between the gallery and the globe or I take the single tube
down through the centre of the chimney and burner and I arrrange a series of wire
arms to project from and to screw into the lower part of the argand burner to
support the shade. In order to avoid an excess of heat being conducted upwards
to the union and to avoid discoloration of the fitting from a like reason I arrange
one or more isolating tubes above the burner surrounding the principal tube.
In accordance with another arrangement I employ the same union as heretofore
or its equivalent for connecting the apparatus to the burner branch or socket of the

page_text: existing gas fitting but instead of the single tube connected thereto being continued
down between the gallery and globe the same is continued upwards and then
branches into a pair of tubes which pass down outside the globe to the argand or
other burner and the shade in this case is supported by wires as in the last
modification a telescopic arrangement being provided to adjust the height and an
automatic or other regulator for adjusting the flame independently of the tap or
cock of the gas fittings. A neat modification of this last arrangement designed to
be used when the globe is removed consists of a pair of tubes leading down to the
burner as aforesaid but termainating at the top in a corona or other ornament to
take the place of the globe in which a regulator may be applied.
This invention further relates to an improved construction of argand burner
for gas fittings wherein the drilling or forming of a series of small holes is avoided
and consists in substituting for such holes a thinner annular slot for the gas to
pass through thas has hitherto been practicable.
.
This is performed by having the burner constructed in two parts the outer
part bored or turned out at the top to the diameter of the flame required and the
inner part being screwed in from the bottom of the outer part and so arranged that
when its nose comes flush with the top of the outer part a thinner annular slot is
left between the two for the gas to pass and thus form the requisite annular flame
this slot being supplied with gas from an annular cavity or chamber which is also
formed or becomes enclosed by screwing the two parts together. I also apply a
disc of metal above the orifice or orifices in this and in other constructions of
argand burner to ensure a more perfect combustion and increased luminousity.
Another improvement upon my former invention consists of a single tube
connected to and suspended from the burner of a gas fitting in accordance with my
invention and having a hook or bracket arranged whereupon to hang. or place a
vessel to be heated say for heating liquids or for cooking or for nursery purposes.

by the said John James Royle in the Great Seal Patent Office on the
7th June 1883.
JOHN JAMES ROYLE of 27 King Street West, Manchester, in the County of
Lancaster, Mechanical Engineer, "IMPROVEMENTS IN SUSPENDED LIGHTS FROM
EXISTING GAS FITTINGS FOR LIGHTING AND HEATING PURPOSES, AND IN BURNERS
FOR THE SAME, AND FOR OTHER PURPOSES."
This invention relates to improvements upon an invention for which Letters
Patent No 5446 were granted to me on the 13th day of December 1881 and has
for its object first to produce a steadier and stronger light and to render the
apparatus applicable to positions where the pressure of gas is low and insufficient
to produce a steady light and also to render the same capable of folding up or
occupying less room for the purpose of packing or carriage from place to place.
And in order that this my said invention may be the more readily seen and
understood I have hereunto annexed a drawing illustrative of my improvements
and will now proceed to describe the same with the assistance of the various
Figures and letters of reference marked thereon.
Fig 1 represents an exterior view of my improved apparatus or "Pendu light."
A is the argand burner (surrounded by a glass chimney A¹) which in this case is
substituted for the ordinary burner which in accordance with the specification of
my former Patent I used as the suspended light. This burner is either supplied
with gas through the tubes which form the support for the shade and which
tubes are gathered into a single tube which passes up between the gallery and
globe as in my former specification or I take the single tube down through the
centre of the chimney and burner and I arrange a series of wire arms to project
from and to screw into the lower part of the argand burner to support the shade
or such argand burner is supplied with gas as illustrated in Fig 1.
In this arrangement I employ the same union B as heretofore (seen in section on
an enlarged scale in Fig 2) or its equivalent for connecting the apparatus to the
burner branch or socket C. of the existing gas fitting but instead of the single
tube D connected thereto being continued down between the gallery and globe the
same is continued upwards and then branches into a pair of tubes D' which pass
down outside the gallery and globe to the argand burner A and thus form two
supporting arms for the shade E as illustrated."
In order still further to support the shade I employ an additional pair of
arms D (a plan view of which is represented in Fig 3) having a socket d in the
centre which fits on to the bottom of the boss carrying the argand burner and is
secured in position by the argand burner. Or instead of having the two additional
arms for supporting the shade both in one piece they may be separate and be
clamped together as illustrated in the sectional view Fig 4 this affords facility for
adjusting the position of the arms to suit the ornamental edge of the shade
when gimped or scolloped on the edge for ornamental effect. The upper edge
of the shade is ornamented by a metallic corona e supporting a mica or talc plate f
to disperse the heat and to prevent injury to the gas fitting.
In Fig 5 I illustrate a more ornamental apparatus or "Pendu light" which
differs from the foregoing inasmuch as the shade which is by preference hexagonal
in form and of a folding character is not supported by its lower edge resting upon
the tubes which supply the burner but a pair of sockets F are provided to receive
the extremities of a pair of wires F projecting upwards from a wire frame which
supports and keeps the shade distended and which wires are clamped in position by

page_text: the binding screws G and thus the shade is suspended in position. In order to prevent
the heat passing upwards too directly and so as to injure the gas fitting I suspend.
a talc or mica plate g immediately over the glass chimney which tends to disperse
the heated current. It will be observed that this double armed arrangement is
designed to be used when the globe is removed from the gas fitting and hence that
the "Pendu light" terminates at the top in a corona or other ornament I which
takes the place of the globe.
In Fig 6 I illustrate by an exterior view and by a sectional view in Fig 7 the
application of a four way tap at the junction of the descending tubes D' and which
being surmounted by a burner K and gallery L for supporting a globe so permits
of the "Pendu light" or ordinary gas light being used either alone or in con-
junction The four way tap J permitting the gas to be turned off entirely from
both "Pendu light" and burner K as seen in Fig 7 or to be turned on to the gas
burner K only as seen in section Fig 8 or to the "Pendu light" only as seen in
section Fig 9 or to both "Pendu light" and burner K as seen in section Fig 10.
Instead of a four way cock a single stop cock may be applied at this junction for
regulating the supply to the argand burner independantly of the tap or cock on the
gas fitting or the same may be effected by a pointed screw D³ as seen in Fig 1 or a
self-acting regulator may be applied for this purpose as illustrated in Fig 11 in
which M is a box containing the ordinary diaphragm and valve or other well
known construction of automatic gas regulator
In Fig 12 I illustrate the application of an inverted ball and socket joint N to
take the place of the union for connecting the "Pendu light" to the arm or bracket
of an ordinary gas fitting the tail. piece N¹ taking the place of the ordinary gas
burner.
In Fig 13 I illustrate a modification of my invention for supporting a glue kettle
or other vessel to be kept heated, it will be apparent that instead of a pair of
tubes o for supplying the burner P that the same may be substituted by a single
tube and that the vessel Q could be suspended on a hook bracket or shelf attached
to such single tube.
In Fig 14 Lillustrate a modification of my invention in which I take a single
tube R from the union S down through the centre of the chimney and argand
burner T and in which I arrange a series of wire arms u to project from and to
screw into the lower part of the argand burner T to support the shade V. In order
to avoid an excess of heat being conducted upwards to the union S and to avoid
discoloration of the gas fitting from a like cause I arrange one or more isolating
tubes W and also a tale or mica plate X above the burner surrounding the
principal tube R and sometimes I interpose an enclosed vessel Y between the
union and gas burner which being filled with carburretting material so increases
the luminousity of the light.
I would here observe that in my provisional specification I mention an improved
construction of argand burner but as I find the same not to be advantageous in
practice I hereby disclaim the same.
Having thus particularly described and ascertained the nature of this my said
invention together with the best methods with which I am acquainted for carrying
, the same into practical effect I wish it to be distinctly understood that I do not
confine myself to the precise details relative proportions or dimensions of the
various parts of my improved apparatus hereinbefore described and illustrated
on the accompanying drawing as the same may be considerably varied without
departing from the invention nor do I confine myself in these improvements to
the use of argand burners as they are more or less applicable to ordinary burners
also but what I desire to claim as improvements upon my former invention as
aforesaid are
1 The use and application to the purpose of an argand burner whereby a
steadier and stronger light is produced even in positions where the gas pressure
is low and insufficient for the ordinary burner. substantially as hereinbefore.
