Improvements in Gas Lamps or Burners.
I, HENRY ANDREW KENT, of 59, Myddleton Road, Bowes Park, in the County
of London, Engineer, do hereby declare the nature of my invention to be as
follows:
-
My invention has for its object to provide a gas lamp, or burner, or burners,
which can be lighted by means of material which will become ignited when gas
comes in contact. therewith, or by means of a pilot light; the lighting being
effected by means of the pressure of the incoming gas itself, without the use of a
bye-pass tap, or of a device depending on the expansion of metal for its operation.
According to my invention I arrange, in the passage by which gas passes to
the burner, or burners, a device which controls two passages for gas, one to the
main burner, or burners, and another to the igniting device, or pilot light, or
igniting devices, or pilot lights, in such a manner that when the gas tap is first
turned to a small extent the gas passes through the passage leading to the
igniting device, or devices, or pilot light, or lights, but not to the passage leading
to the main burner, or burners, as the pressure of the small amount of gas thus
admitted is insufficient to cause the last named passage to be opened. There-
after, when the tap is further turned on, and a greater quantity of gas admitted,
the passage to the main burner, or burners, is opened and the gas passes to the
said burner, or burners, and is ignited, the same movement which opened the
said passage for gas to the main burner, or burners, closing that for gas to
the igniting device, or devices, or pilot light, or lights; it being understood
that when an igniting device, or igniting devices, depending for its, or their,
ignition, on contact of the gas, is or are used, the supply of gas is entirely
cut off when the gas is burning at the main burner, or burners; whilst, when a
pilot light, or lights, is, or are, used, the passage for gas thereto can be always
open to a small extent but be opened to a further extent when the gas tap is first
opened as aforesaid, and, that the passage for gas to the pilot light, or lights,
is again closed to its normal small passage or entirely closed when the main
burner, or burners, is, or are, lighted. The following is a convenient arrange-
ment according to my invention; presuming one burner and one igniter to be
used. In the gas-way, between the gas-tap and the burner, I provide a disc,
or block, having in it a passage for gas to the igniter and another passage for
gas to the burner. Carried by a vertical spindle, mounted so as to be capable of
moving up and down in guides, is a valve, or hood, presenting a comparatively
large surface to the gas and (when the gas is not turned on sufficiently to raise
it) closing the passage for gas to the main burner. When the gas tap is first
turned on to a small extent (which may be indicated by a spring catch entering
CD 77

page_text: gas
a recess, or by a pointer) the pressure of gas is not sufficient to raise the valve,
or hood, to open the passage for gas to the main burner, but gas passes, by the
passage (which is open) to the igniter and the gas ignited thereat. When
the gas tap is further turned on the pressure of increases sufficiently to open
the passage for gas to the main burner by acting on the said valve, or hood, and
so gas passes to the main burner and is ignited thereat by the igniter, the move-
ment thus effected acting, by means of a dise on the aforesaid vertical spindle,
or otherwise, on a valve which closes the passage for gas to the igniter. The
parts remain in this position as long as the lamp is burning. When the tap is
turned to extinguish the light the valve, or hood, closes the passage for gas to
the main burner, and the valve which closes the passage for gas to the igniter
opens ready for gas to pass to the igniter when the gas tap is again operated as
aforesaid. My invention can be applied to gas lamps of various kinds; such as
gas lamps of the ordinary kind, incandescent gas lamps, regenerative gas lamps,
and the like, the passages for the gas to supply the igniter and main burner
respectively, being led thereto by suitably arranged pipes, or passages.
In place of the pressure of gas acting on the valve, or hood, which controls
the passage for gas
to the main burner, it may act upon a diaphragm which is
connected with a valve controlling the said passage.

Improvements in Gas Lamps or Burners.
I, HENRY ANDREW KENT, of 59, Myddleton Road, Bowes Park, in the County
of London, 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:-
My invention has for its object to provide a gas lamp, or burner, or burners,
which can be lighted by means of material which will become ignited when gas
comes in contact therewith or by means of a pilot light the lighting being
effected by means of the pressure of the incoming gas itself, without the use of a
bye-pass tap, or of a device depending on the expansion of metal for its operation.
According to my invention I arrange, in the passage by which gas passes to
the burner, or burners, a simple device which controls two passages for gas, one to
the main burner, or burners, and another to the igniting device, or pilot light, or
igniting devices, or pilot lights, in such a manner that when the gas tap is first
turned to a small extent the gas passes through the passage leading to the
igniting device, or devices, or pilot light, or lights, but not to the passage leading
to the main burner, or burners, as the pressure of the small amount of gas thus
admitted is insufficient to cause the last named passage to be opened. There-
after, when the tap is further turned on, and a greater quantity of gas admitted,
the passage to the main burner, or burners is opened and the gas passes to the
said burner, or burners, and is ignited, the same movement which opened the
said passage for gas to the main burner, or burners, closing that for gas to
the igniting device, or devices, or pilot light, or lights; it being understood
that when an igniting device, or igniting devices, depending for its, or their,
ignition, on contact of the gas, is, or are, used the supply of gas is entirely

page_text: cut off when the gas is burning at the main burner, or burners; whilst, when a
pilot light, or lights, is or are, used there can be always a passage for a small
amount of gas thereto through the tap to keep it alight, but a further amount
of gas passes thereto when the gas tap is first opened as aforesaid, and the
passage for gas to the pilot light, or lights, is again closed completely, or to its
normal small passage, when the main burner, or burners, is, or are lighted by
reason of the valve controlling the passage to the igniter having in it an opening
equivalent to that through the tap when in its closed position. The following
is a convenient arrangement according to my invention presuming one burner
and one igniter to be used. I will describe this with reference to the accom-
panying drawings representing vertical sections with the parts shewn in Figure 1
in the position they are in when the gas is unlighted and Figure 2 shewing the
parts in the position they assume when the gas is lighted. In the gas-way
between the gas tap A and the burner B, I provide a disc, or block, e having
in it a passage d for gas to the pipe 2 leading to the igniter e and another
passage f, for gas to the burner B. Carried by a vertical spindle g, mounted so
as to be capable of moving up and down in guides h, h2 (shewn as in discs
perforated for the passage of the gas) is a valve, or hood, i, presenting a
comparatively large surface to the gas and (when the gas is not turned on
sufficiently to raise it) closing the passage f for gas to the burner B. When
the gas tap A is first turned on to a small extent, (which may be indicated by
a spring catch entering a recess, or by a pointer), the pressure of gas is not
sufficient to raise the valve, or hood, i, to open the passage for gas to the
burner B, but gas passes, by the passage d (which is open) and pipe e to the
igniter e, and the gas is ignited thereat. When the gas tap A is further turned
the pressure exerted by the additional quantity of gas admitted is sufficient to
open the passage f for gas to the burner B by acting on the valve, or hood, i,
and so gas passes to the burner B and is ignited thereat by the igniter e the
movement of the valve i thus effected acting, by means of a disc g² secured to
the vertical spindle g, on a valve j (mounted in the lower guide disc h²) so as
to close the passage d for gas to the igniter e as shewn in Figure 2. The parts
remain in this position as long as the lamp is burning. When the tap A is
turned to extinguish the light, the valve, or hood, i descends and closes the
passage f for gas to the burner B and as the disc g² descends with the valve i
the valve j also descends and opens the passage d, for gas to the igniter ready
for gas to pass to the igniter when the gas tap A is again operated as aforesaid.
My invention can be applied to gas lamps of various kinds, such as gas lamps,
of the ordinary kind, incandescent gas lamps, regenerative gas lamps, and the
like, the passages for the gas to supply the igniter and main burner respectively
being led thereto by pipes or passages arranged to suit the particular kind of
lamp to which the invention is applied.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed I wish it to be
understood that I am aware that prior to the date of my application it has been
proposed to provide, in apparatus for igniting gas, a valve in the main gas
supply pipe which is opened by the gas pressure, and a ball valve in the pilot
jet supply pipe which is closed by the gas pressure at the same time that the main
valve is opened, and I do not claim such construction generally, but I declare
that what I claim is:
1. The combination of a gas tube, a passage for gas from the said tube to the
burner, a pilot jet, a passage for gas from the gas tube to the pilot jet, a hollow
conical valve normally closing the gas passage to the burner, a rod or spindle
connected to the conical valve, a disc or arm on the said rod or spindle, and a
valve carried by the disc or arm to close the gas passage to the pilot jet when
5 the conical valve is moved by the pressure of the gas to admit gas to the burner
substantially as herein before described.

page_text: 2. The combination of parts constituting the improvements in gas lamps or
burners substantially as herein before described and illustrated in the accom-
panying drawings.
