Improvements in Wind Guards for Protecting Exposed Gas Jets.
I, BENJAMIN GREAVES SIMPSON, of 14, Stanley Road, Heeley, Sheffield, in the
County of York, Gentleman, do hereby declare the nature of my invention to be
as follows:-
._
My invention refers more particularly to the open or unprotected gas jets used
outside shop windows but it may be applied to other exposed gas jets not protected
by glass globes or the like, and which are liable to be extinguished by the action
of a strong wind.
I have found that if the flame at its lowest point or where the gas issues from
the burner is protected from the action of the wind, the upper part of the flame
may be exposed without danger of the light being extinguished or blown out,
and thus avoiding much trouble and annoyance.
I therefore propose to protect the lower part of the flame for some little distance
above the burner with the guard, the upper light giving portion being unprotected.
The most common application of my invention is to a line of burners fixed upon
a length of gas piping in which case I construct the guard from a short length of
tube open at the top, and either of round or oval cross section by preference, and
to stand above the burner an inch or rather more as preferred.
The tubular guard may be provided with openings closed with talc to permit
the passage of light, or it may be a plain piece of tubing.
The lower part may be prepared to screw upon the lower part of the burner, or it
may be provided with a split cotter for clasping it to the gas pipe.
Holes or the like are made in the lower part of the guard to admit a supply of
air for combustion.

Improvements in Wind Guards for Protecting Exposed Gas Jets.
I, BENJAMIN GREAVES SIMPSON, of 14, Stanley Road, Heeley, Sheffield, in the
County of York, Gentleman, do hereby declare the nature of this invention and in
what manner the same is to be performed, to be particularly described and ascer-
tained in and by the following statement:-
My invention refers more particularly to the protection of open or unprotected
gas jets such as are used outside shop windows, but it may be applied to other

page_text: exposed gas jets unprotected by glass globes or the like, and which are liable to
be extinguished by draughts and like causes.
I have found by experiment that if the flame is protected from the action of
the wind at its lowest point, that is where the gas issues from the burner, the
upper part of the flame may be exposed without danger of the light being blown
out, but in practice I prefer to carry the protection above such point, and leave
the upper or light-giving portion of the flame unprotected.
The most common application of my invention is to a line of burners fixed upon
a length of gas pipe situated outside a shop window and generally required to be
used during the winter months when the use of glass globes or chimneys is
impracticable.
For such a purpose I use the guards shown in the annexed sheet of drawings
in which
Fig. 1, represents a short piece of gas pipe, with an unprotected burner, and two
protected burners, one guard being in section.
Figs. 2, 3 and 4, show modifications of the guard.
In Fig. 1, I preferably screw the burner A, into a nozzle F, which in turn is
screwed into the top of the gas supply pipe I). The guard consists of a cylindrical
casing B, of brass or other metal, open at the top, and a base with a screw-
threaded hole by means of which it may be screwed upon the nozzle F, and thus
be securely held in position.
It is provided with openings C, glazed with talc for the passage of light, and
also with holes E, 1or the supply of air.
In Fig. 2, I show the form of guard which I prefer; it consists of a piece
of cylindrical brass tube B, having a base plate G constructed to screw upon the
burner nozzle F, and having a number of air openings E. This is simple, effective
and cheap.
In Fig. 3, I am enabled to dispense with the air openings E, by making the
tube or casing of a square, octagonal or other form of cross-section which will
leave air inlets H, round the base G, between it and the casing B.
In cases where plain burners such as the one shown in Fig. 1, are used, a
simple method for securing the guard to the gas pipe D, is shown in Fig. 4,
being a strip of metal I, attached to the bottom edge of the guard, and a short
strip with lugs J, upon the other side.
The long strip is bent round the pipe, the lugs J, clasped over it, and the
extreme end of the strip bent back over the lugs as shown.
Extra air inlets K, may be added if desired, and instead of screwing the guards
upon the nozzle as described, the nozzle may be left plain and the bottom of the
tubular guard be made to fit upon and clasp the nozzle.
Having now particularly described and ascertained the nature of my inven-
tion, and in what manner the same is to be performed, I declare that what I
claim, is:-
1-A wind guard for exposed gas jets, as herein before described and set forth.
2-A tubular guard for exposed gas burners, open at the top and having one
or more air inlets near the bottom, as herein before described, and substantially as
shown in the drawings annexed.
