PROVISIONAL SPECIFICATION.
Improvements in or relating to Gas Fittings.
I, JOHN JAMES ROYLE, of Great Bridgewater Street, Manchester, Engineer,
do hereby declare the nature of my said invention to be as follows:-
"
:-
These improvements refer primarily to an invention for which I obtained Letters
Patent No. 9972 on the 22nd day of August 1885, now known in the market as
Royle's pendu-light" and consist of improved means of supporting the paper
or card board shade whereby I am enabled to fix the shade in a neater and
cheaper manner than heretofore and dispense with the nuts and other fittings
hitherto used.
In accordance with my invention I employ an ordinary Argand burner of which
the gallery portion is attached to the burner by a screw thread formed at or near
the base of the "steatite" and I make use of the method of construction to carry
and firmly hold a ring or collar to which are connected three or more wires
extending radially outwards and upwards to a ring to which they are all joined
and so form a frame. Upon this frame the paper shade rests and is attached
thereto by brass fastenings similar to paper fasteners, the prongs of which, pass
through the substance of the shade from the outside and are bent around the
wire frame on the inside. The shape of the shade may be round, square,
hexagonal, or octagonal the wire frame being formed accordingly.
This improved method of mounting may be applied to Argand burners fitted to
other gas fittings.
To facilitate the connection of the burner to the gas fitting I employ a screw
threaded nipple screwing into the end of the gas pipe and into the burner.
My improvements further consist in providing the pipe or tube of the "pendu-
light" at the part where it bends downwards from the gas joint with a gas jet
or burner in order to afford a light for ordinary lighting purposes in addition to
the suspended light. Said jet may be fitted with a stop cock or tap to open or
shut off the supply of gas and with a gallery to support a globe if desired.

COMPLETE SPECIFICATION.
Improvements in or relating to Gas Fittings.
I, JOHN JAMES ROYLE of Great Bridgewater Street, Manchester, Engineer,
do hereby declare the nature of my said invention and in what manner the same
is to be performed to be particularly described and ascertained in and by the
following statement :-

These improvements refer primarily to an invention for which I obtained Letters
Patent No. 9972 on the 22nd day of August 1885, now known in the market as
'Royle's pendu light" and consists of improved means for supporting the paper or
card-board shade whereby I am enabled to fix the shade in a neater and cheaper
manner than heretofore, and dispense with the nuts and other fittings hitherto used.
And in order that my invention shall be more readily understood and carried
into practical effect I have hereunto annexed a sheet of drawings in which I have
only shewn the shade and burner portion of a pendu-light as being sufficient to
illustrate my present improvements.

page_text: As described in my former Specification a pendu-light consists of an Argand
burner suspended from an ordinary gas bracket or pendant by a tube and gas
tight connection, which tube at its lower end is so bent and fitted with clamping
nuts as to serve the purpose of holding the shade around the light.
In accordance with my invention I dispense with the method described in my
former Specification of supporting the shade and I avail myself of the construction
of the Argand burner to effect the same object. An Argand burner as commonly
used consists of three parts viz.-the burner portion proper (A) (see Figs. 1 and 2),
the "steatite" portion (B) (see Fig. 2) and the gallery part (C) (see Figs. 3
and 4). The burner portion is made with a screw thread at (D) to receive the
gallery (C), and is also formed with a flange (E). I make use of this screw
thread (D) and flange (E) to carry a ring or collar (F.) (see Figs. 5 and 6) which
is slipped over the "steatite" portion after the gallery part (C) is removed. By
replacing the gallery part (C) and screwing it down, the ring or collar is firmly
clamped in position. To this collar or ring (F) is connected the wires (G), (G), (G)
extending radially outward and upward to the ring of wire (H) to which said
wires are all connected as illustrated.
It will be apparent that these wires form a convenient supporting frame for
the paper shade (I) which is simply dropped on to the ring of wire (H) and
then in order to fix it and keep it in proper relation to the chimney of the burner
the shade is fastened by means of a series of paper fasteners (J) the prongs of
which are passed through the substance of the shade and bent round the ring of
wire (H).
In this way I simplify the method of mounting the shade, more effectually
support the same and reduce the cost of the fittings to a minimum. Moreover
by so mounting the shade a greater variety of designs in the tube can be obtained,
the method of supporting the tube as heretofore tending to limit the shape that
could be given to the tube by reason of the lower end, having always to be more
or less of the same formation as the shade.
The wire ring (H) may be round, square, hexagonal, octagonal or other shape
to suit any desired form of shade.
The improved method of mounting the shade may be applied to Argand burners
fitted to other gas fittings than "pendu-lights" in which case to facilitate the fixing
of the burner to any size of gas fitting, I provide a screw threaded nipple (see
Fig. 7) the end (K) screwing into the burner thread of the fitting and the end (L)
into the Argand burner base portion.
Having thus particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I wish it to be understood
that since filing my Provisional Specification I have found that the additional gas
jet or burner therein described is not new being already covered by my earlier
Patent No. 5844" and I therefore desire to disclaim the same and what I do
claim and desire to secure by Letters Patent is.―
.
1st. In pendu-lights and other gas fittings fitted with Argand burners and a
paper or card-board shade supporting the shade by means of a wire frame carried
from a ring or collar adapted to fit onto the Argand burner substantially as
hereinbefore described and illustrated on the accompanying drawing.
2nd. Fixing the paper shade to the wire frame hereinbefore described by "paper
fasteners" for the purpose set forth.
3rd. The nipple shewn in Fig. 7 substantially as and for the purposes set forth.
