PROVISIONAL SPECIFICATION.
Improvements in Protectors for Gas Burners.
1, ALEXANDER ROUND of 15 Fann Street, Goswell Road, in the City of
London, Gas Engineer, do hereby declare the nature of this invention to be as
follows:-
This invention relates to wire "globes" or protectors commonly placed round
gas burners. Hitherto protectors of this description have been usually made of
wire wound spirally in the form of a globe larger at the centre, say half-way up,
and closing in at the top and bottom.
In making my improved "globe" or guard I form it substantially cylindrical,
the top being as large as the largest diameter, the wires being bent in towards the
bottom and all the wires excepting a few rings, say conveniently three, which are
necessary to maintain the shape being arranged vertically so as to interfere as little
as possible with the light. The bottom consists of a plate to screw on to the gas
bracket and a few say half a dozen of the vertical wires which are carried iu,
passed through holes in the plate and secured by bending over. The rest of
the vertical wires stop short at a ring of considerably larger diameter than the
previously described plate so as to leave large open spaces by which the burner
can be lighted.
At the top I leave between the top plate or cover which may conveniently be
made of metal, an open space of perhaps an inch or so in height the cover
being secured upon the ends of those before described vertical wires which are
connected to the central plate; these wires may be made of stronger gauge than
the others.
The central plate may be made of brass or other suitable material conveniently
cast, and I prefer to form a rim, flange or bead upon its outer edge so as to give a
better hold to the wires. If desired the wires may be screwed in, brazed or soldered
to the plate instead of passing through openings in it.

COMPLETE SPECIFICATION.
Improvements in Protectors for Gas Burners.
I, ALEXANDER ROUND of 15 Fann Street, Goswell Road, in the City of
London, Gas 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:—
This invention relates to wire "globes" or protectors commonly placed round
gas burners. Hitherto protectors of this description have been usually made of
wire wound spirally in the form of a globe larger at the centre, say half-way up,
and closing in at the top and bottom.
"
In making my improved "globe' or guard as shown in the accompanying
[Price 8d.1

page_text: perspective view I form it substantially cylindrical, the top being as large as the
largest diameter the wires A A' being bent in towards the bottom and all the wires
excepting a few rings (not spirals as bitherto employed) say conveniently
three BCD which are necessary to maintain the shape being arranged vertically
so as to interfere as little as possible with the light. The bottom consists of a
plate E to screw on to the gas bracket and a few say half a dozen, viz.: A¹ of the
vertical wires A A' which are carried in, passed through holes E' in the plate E
and secured by bending over. The rest of the vertical wires stop short at the
ring B which is of considerably larger diameter than the plate E so as to leave large
open spaces through which access may be had for lighting the burner.
At the top I leave between the top plate or cover F which may conveniently be
made of metal, an open space G of perhaps an inch or so in height the cover F
being supported by the vertical wires A¹ which at their lower ends, as before
described, are connected to the central plate E; these wires A' may be made of
stronger gauge than the wires A.
The central plate may be made of brass or other suitable material conveniently
cast, and I prefer to form a rim, flange or bead E' upon its outer edge so as to give
a better hold to the wires A¹. If desired the wires A' may be screwed in, brazed
soldered, or otherwise secured to the plate E instead of passing through openings E¹
in it as shown.
In the drawing I have represented the upper ends of the wires A¹ as passing
through holes in the cover F which is supported on eyes A turned in said wires;
this forms a convenient way of fitting the cover F in position as it enables said
cover to be readily removed should such be found necessary. I may however
secure F in position by forming hooks at the upper ends of A' said hooks engaging
with the outer edge of F, or in any other convenient manner.
If desired instead of the wires A A' curving inwards to the plate E as shown in
the drawings which arrangement is preferable, they may be bent at an angle
inwards towards E, then if each wire A or A' were bent at right angles the
protector would be of substantially cylindrical form throughout.
The vertical wires A A¹ may be secured to all or either of the rings B C and D
by binding wire not shown in the drawings and the whole (excepting the cover F
which is preferably enamelled or tinned) may be galvanized to unite all the parts
firmly together and protect them against rust.
In protectors for gas burners as hitherto used it has been found that the light
bas been seriously interfered with by the numerous horizontal wires employed in
their construction, the vertical wires not affecting the light to the same extent, it
has therefore been my aim to employ only just sufficient horizontal wires as may be
necessary to properly support the vertical wires and to locate these horizontal wires
at the parts where they will least affect the light that is to say above and below
but not directly opposite the flame.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed, I declare that what
I claim is
1. A wire-formed protector for gas burners of cylindrical forms substantially as
described.
2. A wire-formed protector for gas burners of cylindrical form at the upper
part and of rounded conical or flat form at the lower part substantially as
described.
3. A protector for gas burners formed of a series of vertical wires so connected
together arranged and bent as to form at the upper part a cylinder and at the lower
part a conical rounded or flat end substantially as described.
4. In a protector such as described the combination with a series of vertical
wires of two or more rings such as B C D substantially as described and illustrated
in the accompanying drawings.

illustrated in the accompanying drawings.
