COMPLETE SPECIFICATION..
Improvements in or relating to Gas Burners.
I, HENRY BAYLEY, trading as Bayley Brothers, of Selborne Works, Walsall
in the County of Stafford, Electrical Fitting Manufacturer, 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 improvements in gas burners for use, alternatively, for
intermittent heating purposes, and for lighting, such as described in Lavender's
Patent Specification No. 2198 of 1890; and has for its object an improved
description of valve mechanism for use with such burners, and improved means for
use in opening and keeping open the passage-way for gas when the burners are to
be used for lighting.
In order that the nature of the invention, and convenient means of carrying it
out, may be readily understood, I will proceed to describe it with reference to the
drawings herewith, which illustrate the invention applied to a burner which may be
screwed into an ordinary gas bracket.
Figure 1 is a vertical section of the burner, shewing the operative parts in
position as when the passage-way for the gas is restricted;
Figure 2 is a corresponding section, but shews the parts in the position as when
the passage-way is fully open for lighting.
Figure 3 is a side elevation of the burner as seen when the parts are in the
position shewn by Figure 2.
Figure 4 is a sectional plan taken on line of Figure 1; and
Figure 5 is a plan of Figure 3.
A cylindrical inner tube or case A, drawn preferably in sheet brass, has formed
as a downward extension thereof a tapered portion a of reduced diameter, which
is screwed for connection with an ordinary gas bracket or corresponding part.
This tube fits up tightly into a cap or outer case B which is formed at the top
similarly as ordinary burners, or otherwise in a manner to form a suitable nozzle
for the gas to issue through for burning; and the joint between the inner and outer
cases may be made gas-tight by white lead or the like. A plate b is fitted down
tightly into the case A, and a hole c is formed through it for the passage of the
gas. A valve C, formed as a heavy lump of metal circular on plan, and of a
diameter to fit sufficiently loosely within the case A to allow free passage of gas
between itself and the wall of the case, rests on the plate. This valve is flat on
its underside, and when it lies flat upon the plate b, as shewn by Figure 1, it covers
the hole c and would prevent entirely the flow of gas therethrough were it not for
a small channel, formed in the face either of the plate or valve, which allows
sufficient gas to flow through to keep up a small flame at the top of the burner.. A
portion of the under face of the valve is formed as cut away on the side which is
remote from the hole c, and the lower end of a rod d of very small diameter is
pivoted to such side of the valve as shewn, and the rod passes up through the top
of the case B and projects thereabove. The valve is formed also, preferably, as
cut away for some distance down from the top on the side to which the rod d is
pivoted, for the purpose of ensuring that nearly all the weight of the valve shall
be on the opposite side of the edge e of the valve to that on which the rod d is
pivoted. When the rod d is pressed down (such as when an article or substance to
be heated presses thereon) the valve C is tilted up on its edge e, as shewn by
Figure 2, and a full supply of gas can pass through the hole c to the nozzle of the
burner; but immediately pressure is removed from the top of the rod the weight
of the valve causes it to fall flat upon the plate b, as shewn by Figure 1, thus
closing the hole c except for the small channel referred to above, and this movement
of the valve of course raises the rod again into its normal position. An arm D is

page_text: pivoted at to the outside of the cap B, and its outer end g is bent over at right
angles, or approximately so, to the main portion of the arm; and an arm E, formed
conveniently of a curved shape on plan, as shewn at Figures 4 and 5, and having a
weight F at its outer end, is fixed at its inner end to the arm D, either by forming
its inner end as a spindle upon which the arm D is fixed or by fixing it and the
arm D to a common spindle. Normally, the arm D is down in the position shewn
by Figure 1, and the arm E in the position indicated by broken lines in the same
figure; but, when it is desired to use the burner for lighting, the arm E is moved
over by means of a pen, pencil, or other instrument, or even by the finger if done
quickly, far enough for the weight to fall over on the other side of the pivot centre,
with the effect that the weight falls into the position indicated by broken lines
Figure 2, bringing over the arm D as it does so and causing the turned-over end g
thereof to press upon and move down the rod and tilt up the valve C into the
position shewn by Figure 2. The weight, of course, continues to hold down the
rod, through the medium of the arm D, so long as it remains in the position shewn
by Figures 2, 3 and 5; but, when it is desired to use the burner again for inter-
mittent heating, the arm E is raised again until the weight has reached a point
from which it will fall back again into the position shewn by Figures 1 and 4.
The arm E might, of course, be pivoted in position to bear upon the rod d
when turned over in one direction; but I do not consider such an arrangement-so
convenient as the one described in which the arm D is employed.
It is preferred to put a disc of brass wire gauze h within the inner case A,
immediately below the plate b, and two or three thicknesses i of such gauze
immediately below the nozzle, to prevent the rushing noise which might otherwise
be heard when the burner is full on, and give a clearer flame.
The valve and other parts of the burner illustrated are different from those of
the burner for alternatively heating and lighting described in Lavender's said
Specification and shewn on his drawings, but it will be obvious that the means
above described of opening the valve and retaining it open, when the burner is
required for lighting, are applicable also to such burner.
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, in respect of a gas burner to be used alternatively for heating articles or
substances held or placed thereover, and for lighting, is :-
1. A pivoted turning piece which, as it is turned in one direction, presses down a
part which passes through the upper portion of the burner and thereby opens the
valve, and as it is turned back again allows the valve to close and cut off the main
flow of gas, substantially as described.
2. A weighted arm used in adapting the burner alternatively for intermittent
heating and lighting, substantially as described.
3. The combination of a weighted arm capable of being moved over on to
opposite sides of its pivoted centre, with an arm fixed to turn therewith and formed
so that when the weighted arm is turned over in one direction the other arm
operates to open the valve and allow a full supply of gas to pass, and when the
weighted arm is turned back again the other arm allows the valve to close again
sufficiently to cut off the main flow of gas, substantially as described.
4. The combination of valve C and rod d substantially as described, operating
substantially in the manner set forth.
5. The combination with the tilting valve C and rod d, of the means substantially
as described, with reference to the drawings herewith, by which the rod may be
depressed and the valve tilted up and retained in such position when the burner is
to be used for lighting.
