Improvements in connection with Gasaliers and the like for Carrying
Away the Smoke and Noxious Gases, and for Preventing the
Ceiling being Discoloured thereby.
1, HERBERT HUMPHRIES, of High Street, Brierley Hill, in the County of Stafford,
Auctioneer, 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 :-
This invention has reference more particularly to sliding gasaliers, gas pendants,
chandeliers, and the like, which are arranged so that their height can be adjusted and
so that they can he swung round on a central tube hanging from the ceiling or
other support, but is also in part applicable to fixed gasaliers, gas pendants chandeliers
and the like, and the object of this invention is to provide improved means for carrying
the shade or shades over the burner or burners so that when the gasalier or the like is
movable such shade or shades will move therewith and at all times be in position over
the burner or burners so as to prevent the ceiling being discoloured by the smoke
arising therefrom and so as to carry away the smoke and noxious gases from the
burner or burners.
In carrying out this invention I prefer to support the shade or shades as hereinafter
described from the central outside tube of the gasalier or the like so that the shade or
shades will move with the gasalier or the like when the same is turned raised or
lowered and always be at the same distance and position above the burner or burners.
I will describe my invention by referring to the accompanying sheets of drawings
on which Fig. 1 represents a two armed gasalier provided with my improved means
for supporting the shades over the burners, and Fig. 2 is a part of the same separately;
Fig. 3 represents a modification of the same, and Fig. 4 is a further modification;
Fig. 5 is a further modification in which the parts which support the shades are con-
structed so as to carry away the smoke and noxious gases from the burners, and Fig. 6
represents a part of the same in detail.
The same letters of reference indicate the same or corresponding parts in all the
Figures of the drawings.
Referring firstly more particularly to Figs. 1, 2, 3 and 4, a is the central outer
tube of the gasalier and 61 62 are the two burners of the same. c¹² are glass or
other shades of usual construction supported over the burners by the rods or tubes d¹ d²
fixed to the central tube a by any convenient means such as by the clip or support e,
represented on an enlarged scale by Fig. 2, which is formed so as to clip the tube a
and is provided with a screw f by which it can be tightened thereon, the tubes d' d²
being fitted in and secured to the eyes e¹ e². It will be seen that when the
gasalier is either raised lowered or turned round the shades c¹² will move with it
and always retain the same position over the burners 61 63 and thus effectually prevent
the ceiling being discoloured by the smoke or fumes arising from the flames. The
clip e is a convenient means of attaching the tubes or rods d'ď to the tube a as it
enables the height of the shades to be adjusted above the burners as may be required
and enables my 'invention to be readily applied to existing gasaliers, gas pendants,
chandeliers, and the like, but other means of carrying the shades c² c³ from the central
tube a may be used such as by arms fixed to the central tube a and forming part of
the gasalier chandelier or the like as shewn for instance by dotted lines in Figure 1;
or the rods or tubes which carry the shades may be made removable from the eyes
which are attached to or formed with the central tube a as for instance in the example
illustrated by Fig. 3 where the lower end of the tube d' is formed with a spigot d³
for fitting in the eye e². The central connection illustrated by Fig. 4 is intended to
take the place of the clip e and is arranged to carry four arms for shades and is
made solid and fixed in position on the tube a by a set screw g.

page_text: The tubes d' which carry the shades above the burners may be constructed so as
to convey the smoke and fumes from the burners to the usual ventilator at the top of the
gasalier or the like thus improving the ventilation of the room in which the gasalier
is burning and preventing any objects in the room being tarnished or discoloured by
the gas fumes. This I effect (see Figs. 5 and 6) by turning the open ends of the
tubes d upwardly towards the ventilator and by using shades which have an
upper opening c³ communicating with a hole d³ in each tube through which the smoke
and fumes from the gas-light can pass and up through the tubes to the ventilator h.
In order to more effectually convey the fumes and smoke from the upper open ends of
the tubes d' d² to the ventilator h these tubes may be arranged to slide telescopically
either inside or outside either of the tubes which are carried from the fixed inner
central tube of the gasalier or the like and this can very conveniently be done by
making eyes 12 on the bracket k which carries the rollers of the counterbalance
chains these eyes 12 being adapted to take the tubes 12. In this example the
shades ce can very conveniently be suspended from the tubes d' d so as to be
readily removed therefrom and readily replaced, by employing a hook m fixed in each
of the tubes d d and projecting through the holes d³ on to which the shades can be
hung by a wire loop such as n; an ornamental metal rosette such as o being after-
wards slipped on to each of the tubes to cover the hooks and lead the smoke and
fumes from the shades c' c² to the tubes d¹ d².
It will be evident that my invention can be similarly applied to those gasaliers, gas
pendants chandeliers and the like which are provided with more or less than two arms
and burners similarly as above described and illustrated with reference to a two
armed gasalier.
Whilst not limiting myself to the precise details herein before described and
illustrated by the accompanying drawings, 1 would have it understood that I do not
make any exclusive claim to a shade carried by a gasalier, gas-pendant, chandelier,
or the like either when such shade is made to carry off the smoke and fumes or not,
as I am well aware that such shades have been used prior to my invention, but,
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 I
claim is :-
1. The combination with the movable part of a gasalier gas-pendant or the like, of
an arm or arms carried thereby and extending above the gas burner or burners such
arm or arms being formed substantially as hereinbefore described for suspending a
shade above the said burner or one of the said burners, for the purpose and sub-
stantially as herein before set forth.
2. The bereinbefore described improved means for supporting a shade above the
burner, or shades above the burners, of a gasaliér gas-pendant or the like, consisting of
one or more tubes rods or arms fixed or detachably connected to a clip or central
support adapted to fit on to the central tube of a gasalier gas-pendant or the like the
outer end of such tube rod or arm, or the outer end of each of such tubes rods or
arms, being formed so as to carry a shade over the gas burner, for the purpose and
substantially as herein before set forth.
3. A clip or support adapted to fit on to the central tube of a gasalier or the like
and having sockets or eyes for holding the tubes rods or arms which carry the shades
over the burners, substantially as hereinbefore set forth.
4. The combination with the movable part of a gasalier or the like of an upwardly
extending pipe or pipes carried thereby such pipe, or each of such pipes, extending
from above the burner or one of the burners of the gasalier or the like to near the
upper part of the central tube of the same and carrying at its lower end an open
topped shade over the gas burner such shade communicating with the pipe by which
it is carried so that the smoke heated air and gases from the flame will pass up the
said pipe, for the purpose and substantially as hereinbefore described.
5. The combination with the movable part of a gasalier or the like of an upwardly
extending pipe or pipes carried thereby such pipe, or each of such pipes, extending

page_text: from above the burner or one of the burners of the gasalier or the like to near the
upper part of the central tube of the same and fitting inside or outside a pipe or pipes
carried by the fixed internal tube of the gasalier or the like the said pipe or each of
the said pipes carried by the said movable part carrying at its lower end an open
topped shade over the gas burner such shade communicating with the pipe by which
it is carried so that the smoke heated air and gases from the flame will pass up the
said movable and fixed pipes, for the purpose and substantially as hereinbefore
described.
