improvements in incandescence vapour Lamps.
I, HENRY HARRIS LAKE, of the Firm of Haseltine, Lake & Co., Patent Agents,
45, Southampton Buildings, in the County of Middlesex, do hereby declare the
nature of this invention to be as follows:
My invention relates to incandescent vapour-lamps; and it consists in features
of construction and novel combinations of parts in such lamps, as hereinafter
described.
The construction and general arrangement of my improved lamp are as
follows:
A body portion containing the shut-off valve and the air-mixing tube and sup-
porting the lamp-globe and the burners, is suspended by curved tubes from a
ceiling-piece or other suitable device. The oil-supply, pipe passes down through
the ceiling-piece and the curved tubes which form the lamp-support and enters
the body portion, which is preferably cylindrical in form, the lower part being
detachable and provided with a hemispherical bottom. The lower part of the
casing can be removed after unscrewing and removing the stem of the valve by
rotating the casing sufficiently to release the bayonet-notch and drawing the body
downward.
The feed-pipe is connected by a union or similar device to a cut-off valve, the
stem of which passes down through the body portion, so as to be operated from
without.
The generating-pipe which, together with the cut-off valve and the atomizing
valve forms a single removable element of the lamp, extends up parallel and
adjacent to the burners, and, curving over near the top of the burners, extends
down parallel with them, terminating in the atomizing-valve.
For adjusting the height of the generator and the atomising-valve a clamp
adapted to hold the pipe securely in position, is fixed to the burner-body. The
air-mixing chamber extends downward from the atomizing-valve into the body,
of the lamp and thence curves upwardly to the burners.
The entire light-producing mechanism of the lamp may be supported by a
single piece, as a casting extending across the body and secured thereto by
screws or otherwise.
The air-mixing tubes are secured to the piece by lateral recesses therein, the
edges of these recesses being provided with set-screws or other suitable means
for clamping the tubes. At the receiving end of the air-mixing tube is provided
a device for controlling the admission of air to the tube. This air-regulator is
DQ11

page_text: constructed and operated in the following manner: The atomizing-valve has
an approximately flat or blunt lower end, and the end of the air-mixing tube
is internally threaded to receive a screw-cap. The cap is provided centrally with
a hole for passage of vapor from the atomizing-valve. It is evident that after
approximately adjusting the height of the valve above the tube by means of the
clamp above mentioned a further adjustment of the air-supply, which is con-
trolled by the space or opening between the valve and cap, may be secured by
turning the screw-cap thus varying the opening for passage of air to the mixing-
tube. This improved regulator is an essential feature of my invention.
When it is desired to remove the valve and generator for cleaning or other
purpose, it is only necessary to remove the lower part of the lamp-body, which is
preferably secured to the upper part by a bayonet-notch and pin or other suit-
able means and to loosen the union and clamp. The generator may then be
taken out without disturbing other portions of the lamp.
The mixing-tube and burner supports may be readily removed from the lamp
by removing the screws which secure the supporting-piece to the lamp body at
a point above the connection thus allowing the tube and burners to be drawn
down through the upper part of the lamp-body.
When the light is not in use, the supply of oil may be shut off by closing the
valve; but it is frequently desirable to admit sufficient oil through valve to keep
the burners heated, thus continuously generating oil-vapour in the tube, so that
the lamp will light automatically when the valve is opened. I accomplish this
purpose by attaching the stop to the stem of the shut-off valve. A stop-pin is
provided on the part of the lamp-body through which the valve-stem passes, and
a pointer, adapted to be adjustably clamped to the stem, is arranged to turn with
it in such manner that the pointer will strike the stop-pin and prevent further
turning of the stem when the valve is sufficiently closed.
By the means, herein described I am enabled to produce a continuously-
generating lamp that is practically self-lighting, is easily taken apart for renewal
or cleaning, simple in construction, and inexpensive to manufacture.

Improvements in Incandescence Vapour Lamps.
I, HENRY HARRIS LAKE, of the Firm of Haseltine, Lake & Co., Patent Agents,
45, Southampton Buildings, in the County of Middlesex, 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 relates to incandescence vapor-lamps; and it consists in features
of construction and novel combinations of parts in such lamps, as hereinafter
described and claimed.
In the accompanying drawings,
Figure 1 is a front view of the lamp as it appears complete. Figure 2 is a
front view of the interior arrangement of my lamp, the case and globe being
shown in section. Figure 3 is a side view of the same. Figure 4 is an enlarged
detail of the atomizing-valve and the end of the mixing-tube with the air-regu-
lator attached. Figure 5 is a detail of the stop attached to the shut-off valve.

page_text: Figure 6 is a detail showing the clamp for adjusting the height of the generator.
Figure 7 is a detail of the tube-supporting device.
The construction and general arrangement of my improved lamp are clearly
shown in Figures 2 and 3 of the drawings.
A body portion A, containing the shut-off valve and the air-mixing tube and
supporting the lamp-globe C and the burners, is suspended by curved tubes from
a ceiling-piece B or other suitable device. The oil-supply pipe passes down
through the ceiling-piece B and the curved tubes which form the lamp-support
and enters the body portion A, which is preferably cylindrical in form, the lower
part being detachable and provided with a hemispherical bottom. The lower
part of the casing A can be removed after unscrewing and removing the stem of
the valve 2 by rotating the casing A sufficiently to release the bayonet-notch at d
and drawing the body A downward.
The feed-pipe 1 is connected by a union or similar device 1ª to a cut-off valve 2,
the stem of which passes down through the body portion A, so as to be operated
from without.
The generating-pipe 3, which, together with the cut-off valve 2 and the
atomizing-valve 4, forms a single removable element of the lamp, extends up
parallel and adjacent to the burners, and, curving over near the top of the
burners, extends down parallel with them, terminating in the atomizing-valve 4.
For adjusting the height of the generator and the atomizing-valve a clamp 5,
adapted to hold the pipe 3 securely in position, is fixed to the burner-body.
The air-mixing chamber 6 extends downward from the atomizing-valve into the
body A of the lamp and thence curves upwardly to the burners.
The entire light-producing mechanism of the lamp may be supported by a
single piece, as a casting 7, extending across the body A and secured thereto by
scrows or otherwise.
The air-mixing tubes are secured to the piece 7 by lateral recesses 7" therein,
the edges of these recesses being provided with set-screws or other suitable means
for clamping the tubes. At the receiving end of the air-mixing tube is provided
a device for controlling the admission of air to the tube. This air-regulator is
constructed and operated in the following manner: The atomizing-valve 4,
Figure 4, has an approximately flat or blunt lower end, and the end of the air-
mixing tube is internally threaded to receive a screw-cap 8. The cap 8 is pro-
vided centrally with a hole for passage of vapor from the atomizing-valve. It
is evident that after approximately adjusting the height of the valve 4 above
the tube 6 by means of the clamp 5 above mentioned a further adjustment of the
air-supply, which is controlled by the space or opening 9 between the valve 4
and cap 8, may be secured by turning the screw-cap 8, thus varying the opening
for passage of air to the mixing-tube. This improved regulator is an essential
feature of my invention.
When it is desired to remove the valves and generator for cleaning or other
purpose, it is only necessary to remove the lower part of the lamp-body A, which
is preferably secured to the upper part at d, Figure 1, by a bayonet-notch and
pin or other suitable means and to loosen the union 1ª and clamp 5. The
generator may then be taken out without disturbing other portions of the lamp.
The mixing-tube and burner supports may be readily removed from the lamp
by removing the screws 7, which secure the supporting-piece 7 to the lamp-body
at a point above the connection, thus allowing the tube and burners to be
drawn down through the upper part of the lamp-body A.
When the light is not in use, the supply of oil may be shut off by closing the
valve 2: but it is frequently desirable to admit sufficient oil through valve 2
to keep the burners heated, thus continuously generating oil-vapor in the tube 3,
so that the lamp will light automatically when the valve 2 is opened. I accom-
plish this purpose by attaching the stop shown in Figure 5 to the stem of the
shut-off valve. A stop-pin is provided on the part of the lamp-body through
which the valve-stem passes, and a pointer, adapted to be adjustably clamped to
"

page_text: the stem, is arranged to turn with it in such manner that the pointer will strike
the stop-pin and prevent further turning of the stem when the valve is sufficiently
closed.
By the means herein described I am enabled to produce a continuously-
generating lamp that is practically self-lighting, is easily taken apart for renewal
or cleaning, simple in construction, and inexpensive to manufacture.
Having now particularly described and ascertained the nature of the said in-
vention and in what manner the same is to be performed, as communicated to
me by my foreign correspondent, I declare that what I claim is:
-
1. In an incandescence vapor-lamp the combination with the lamp-body of a
removable generator-pipe having an atomizing-valve and a shut-off valve attached
thereto; a removable mixing-tube having a burner integral therewith and adapted
to support said generator-pipe; and means substantially as described for regu-
lating the air-supply by varying the distance between the atomizing-valve and
the opening of the mixing-tube.
2. An incandescence vapor-burning lamp combining a removable generator-
pipe having an atomizing-valve and a shut-off valve attached thereto and form-
ing an integral part therewith; a removable mixing-tube supported by the body
of the lamp, said mixing-tube being provided with means for adjustably clamping
the generating-tube and for regulating the distance between the opening of said
mixing-tube and the atomizing-valve, together with a stop for regulating the
closure of the shut-off valve, substantially as and for the purpose described.
