proved Vibration Globe and (or) support for
Incandescent Gas Lamps.
I, ANDREW WREN, of 167 King Street, Pollokshaws, near Glasgow, Plumber and
Gas-fitter, do hereby declare the nature of this invention to be as follows:-
This invention relates to an anti-vibration globe and (or) support for incan-
descent gas lamps.
In carrying out the invention I use a glass globe or support preferably of
cylindrical shape and provided with a flat or round bottom. This bottom has a
large central perforation in it and also two or other number of small holes for
the admission of air. The upper edge of this globe is preferably provided with a
bead or flange to which is secured a brass or other cover provided with a central
raised part. A number of air-holes are made in this cover. The cover and the
globe are suspended preferably by means of a spring from an over-head rod or
cross-bar carried by the upper end of the usual lamp globe. This globe is sup-
ported or held in place by any well known arrangement of support.
The usual incandescent burner and chimney is fitted within the globe or support
and the gas inlet tube projects down through the large central hole at the bottom
of the globe. The burner is secured in place in the globe in any suitable manner.
The gas inlet tube of the burner is connected by means of an india-rubber or
other flexible pipe with the source of gas supply. The india rubber pipe passes
down through a hole in the bottom of the usual outer globe.
In certain cases the outer globe may be dispensed with. The cover may be
jointed to the inner globe or support by means of snugs and screws or other
suitable devices.
With this arrangement the burner is suspended by a spring suspension at the
top and has an elastic connection at the bottom so that it is not subject to the
same vibration as with the present arrangements.

page_text: I, ANDREW WREN of 167 King Street, Pollokshaws, near Glasgow, Plumber and
Gas-fitter, 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 relates to an anti-vibration globe and (or), support for incan-
descent gas lamps.
And in order that iny said invention may be properly understood I have here-
unto appended an explanatory sheet of drawings, whereon,
Fig. 1 shows one form of the device in side view the glass globe being
sectioned.
Fig. 2 is a vertical section of another form of the device.
Figs. 3 and 4 are detail views.
In carrying out the invention I use a glass globe or support a which may be of
any suitable shape or pattern but is preferably made of a tapered globular shape
as shown at Fig. 1 or a cylindrical shape as shown at Fig. 2. Fitted to the beading a
at the lower edge of the globe is a bottom consisting of a ring b (see also plan view
Fig. 4) having three or other number of radial arms springing from a central
collar 2. This bottom is secured to the beading a¹ by means of pinching screws c
in the same manner as an ordinary gas burner gallery. Passed through the
collar is the gas pipe & which is held in place by means of the nut e² on the one
side and the screwed lower end e¹ of the incandescent burner e.on the other side.
The burner can be of the usual construction. Held in place above the gallery is a
mica or metal disc f having a central perforation in it for the passage of the gas
tube d and also two or other number of small holes for the admission of air. The
upper edge of the globe or support a is provided with an external bead or flange
such as a² to which is secured a brass or other cover 9 provided with a central
raised part g. The cover can be secured to the globe by pinching screws c¹. The
cover may be perforated with holes or it may have a top h inserted in its raised.
part g. This top h can be perforated as at and it may also be provided with a
central cone. Secured to the raised part g' of 'the cover is a. wire or other
suspender i which can be attached by a hook to any suitable support.
jare two wires which spring upwards from the bottom e¹ of the burner and carry
the usual channel ring (Fig. 2 and also Fig. 3) which can have two vertical cuts
or nicks in it as indicated at 2, Fig. 3, which is a plan view of the ring and
cover the ring being shown dotted. The cover can be easily locked to the
ring, in the manner of a bayonet joint fastening, by merely inserting the bent
lower ends of the suspender i in the aforesaid nicks and then giving the cover g
a slight turn so as to cause the inwardly projecting ends it to catch on the upper
flange of the channel ring as indicated in Fig. 3. When the ring j is locked to
the cover g the burner with its connections is firmly supported by the wires ; so
that should the glass a be broken the burner will not fall out of position.
The device can be suspended in any well known and suitable manner from the
top of the lamp or from a bracket or such like.
The pipe of the incandescent burner is connected by means of an india rubber
or other flexible pipe connection, such as n, with the source of gas supply
Fig. 1 is a gas tap with a by-pass regulating screw o' fitted to the gas supply
pipe p.

page_text: The cover g can be secured to the globe a by means of screws c' alone or screws cl
and bent snugs c² as indicated in dotted lines at Fig. 2 and in full lines at Fig. 3.
If desired the globe a may be made large enough to contain two, three or other
number of incandescent burners e. If, say, three burners are used' one can be
secured to each arm of the gallery band be arranged to communicate with cored
eut pasages in the arms as indicated at Fig. 4. Each of these passages can be
made to communicate with a single gas tube made in one with or connected to
the central part 2 of the gallery which in this case would be made in the form of
a hollow box or chamber.
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 consider
novel and desire to claim is:-
1. In combination, an incandescent burner (or burners), a globe or support for
the burner (or burners), a flexible connection between the burner (or burners) and.
the gas supply pipe and means for suspending the burner (or burners) and its globe
or support, substantially as herein before set forth.
2. The construction or arrangement and combination of parts of the device
substantially as hereinbefore described and shown in the drawings annexed or any
mere modification thereof.
