Sections 18 to 21 of the Patents, Designs, and Trade Marks Act, 1883.
We, JAMES LYLE, of 29 Causeyside, Paisley, in the County of Renfrew, North
Britain, Engineer, and JAMES BALLANTYNE HANNAY, of Cove Castle, Loch Long,
in the County of Dumbarton, North Britain, Chemist, do hereby declare the
nature of this Invention to be as follows: that is to say:-
This Invention relates to lamps arranged for burning mineral or other suitable
oil or tar in the form of spray, the spray being produced by the action of compressed
air. The burner of a spray lamp of this kind comprises a cup or combustion
vessel having a nozzle projecting up through its bottom and formed or fixed on the
upper end of what may be termed the air pipe which air pipe has the oil pipe
centrally within it terminating in a nozzle within the air-pipe nozzle.
By the present Invention separating apparatus is employed to free the compressed
air from moisture or water; and arrangements are made for heating the air and for
heating the oil by means of the heated air.
The apparatus for separating moisture consists of a sinall vessel which may be
conveniently attached to the side of the drum or vessel containing the oil and from
which drum the air and oil pipes extend up to the burner. This separating vessel
which is provided with a trap valve or with a stopcock at its lower end for
periodically drawing off water, has an inlet for the compressed air near its upper
end, whilst the outlet by which the air passes onwards to the air pipe of the lamp
is at the top of the vessel. Between the inlet and outlet one or more plies of wire
gauze or other suitable filtering material is placed; and when the air passes
through on its way to the lamp any moisture in the air is kept back by the filtering
material and gradually accumulating drips down to the bottom of the vessel.
After leaving the moisture-separating vessel the compressed air is led up a small
pipe which extends up a larger pipe having its upper end closed, the combination
of pipes being curved or inclined if necessary so that its upper part may be acted
on by the flame of the lamp. The air passing up the small pipe descends between
it and the larger pipe and is then led into the main air pipe of the lamp in which
pipe it surrounds the central oil pipe and a portion of it issuing between the inner
and outer nozzles throws into spray the oil issuing from the inner nozzle. The oil

page_text: pipe is made of a metal which is a good conductor and is comparatively thin and
of large size so that the oil rising up it slowly may become heated by the heated
air which is in the space between the inner and outer pipes. Both the inner and
outer pipes extend down to the middle of the bottom of the drum this middle
part being by preference raised so that sediment in the oil may pass to the sides.
A perforated shield or strainer is placed round the lower end of the pipes to keep
sediment from choking the perforations of the pipes. There is a small perforation
in the air pipe just below the top of the drum for the air pressure to have access to
act on the surface of the oil so as to force it up the oil pipe. The air pipe is also
made with perforations at its lower end, and when the compressed air is first
turned on a considerable portion of it enters the drum through these lower per-
forations and passing up through the oil drives. off sediment and facilitates the
passage of the oil up to the burner.
The outer nozzle is. adjusted, relatively to the inner one by screwing up or down
a tube carrying the nozzle and cup and which is screwed into a coupling piece to
which the side branch for admitting the compressed air is attached. Or the cup
in the bottom of which the outer nozzle is by preference formed may be screwed
up or down on the short connecting tube. Handles or projections are provided
for conveniently turning the parts when adjusting them, and also for turning the
part carrying the air-heating pipes so that these pipes may be placed in the best
position when the spray flame is exposed to air currents or wind.

page_text: We, JAMES LYLE, of 29 Causeyside Paisley, in the County of Renfrew, North
Britain, Engineer, and JAMES BALLANTYNE HANNAY, of Cove Castle, Loch Long,
in the County of Dumbarton, North Britain, Chemist, 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:-
that is to say:-
This invention relates to lamps arranged for burning mineral or other suitable
oil or tar in the form of spray, the spray being produced by the action of
compressed air. The burner of a spray lamp of this kind comprises a cup or
combustion vessel having a nozzle projecting up through its bottom and formed or
fixed on the upper end of what may be termed the air pipe, which air pipe has the
oil pipe centrally within it terminating in a nozzle within the air-pipe nozzle.
By the present Invention separating apparatus is employed to free the compressed
air from moisture or water; and arrangements are made for heating the air and
for heating the oil by means of the heated air.
A spray lamp as made with our present improvements is shown on the accom-
panying sheet of explanatory drawings, figure, 1, being a vertical section. Figure, 2,
is a vertical section as at right angles to figure, 1, of one of the connections; and
figures, 3, and 4, are enlarged sections of the same part as modified for directing the
flame of the lamp in an inclined or horizontal direction instead of vertically as
with the lamp shown in figure, 1. In these drawings the same reference numerals
are used to mark the same or like parts wherever they are repeated.
The apparatus for separating moisture from the compressed air consists of a
small vessel, 5, which may be conveniently attached as shown to the side of the
drum or vessel, 6, containing the oil and from which drum the air pipe, 7, and oil
pipe, 8, extend up to the burner. The separating vessel, 5, which is provided
with a trap valve, or as shown, with a stopcock, 9, at its lower end for periodically
drawing off water, has an inlet nozzle, 10, for the compressed air near its upper
end, this nozzle being shown as adapted for receiving the end of a flexible tube
through which the air is conveyed from the reservoir of the air-compressing
apparatus. To the top of the vessel, 5, there is fixed an outlet nozzle, 11, through
which the air passes onwards; and inside the vessel there is fixed a pipe, 12,
dipping some distance below the inlet, the entering air having to pass first down-
wards and then to return upwards through the dipping pipe, 12.
This simple
arrangement has been found more effective for the separation of moisture from the
air than the wire gauze or other filtering material through which we proposed to
pass the air.
.
From the outlet nozzle, 11, of the moisture-separating vessel, 5, the compressed
air is led by a flexible pipe, not shown by dotted lines-to a nozzle, 13, fixed to

page_text: parts connected to the burner, the flexible-pipe allowing of those parts being con-
veniently detached from the drum, 6, for cleaning or other purposes. The nozzle, 13,
admits the compressed air to the bottom end of a small pipe, 14, which extends up a
larger pipe, 15, having its upper end closed, the combination of pipes, 14, 15, being
curved or inclined so that its upper part may be acted on by the flame of the lamp.
The air passing up the small pipe, 14, descends between it and the larger pipe, 15,
and is then led through a horizontal branch and coupling, 16, into the main air
pipe, 7, of the lamp in which pipe, 7, it surrounds the central oil pipe, 8, and a
portion of it issuing between the inner and outer nozzles, 17, at the top throws
into spray the oil issuing from the inner nozzle. The oil pipe, 8, is made of a
metal which is a good conductor of heat and comparatively thin and of large size
so that the oil rising up it slowly may become heated by the heated air which is
in the space between the inner and outer pipes, 8, 7.
The cup or combustion vessel, 18, is set in a cup, 19, which is formed with a
central tubular part, 20, projecting up from its bottom and into the upper cup, 18;
and this part, 20, has the outer one of the two nozzles, 17, formed on it. The
cup, 19, is by means of handles, 21, screwed upon a tube, 22, which forms an
upward extension of the air pipe, 7, and leads the air into the tubular part, 20, of
the cup, 19. The inner oil pipe, 8, is stationary and an accurate adjustment is
effected between the nozzles, 17, by screwing the cup, 19, a jam nut, 23, with
handles being provided for firmly securing the parts after being adjusted.
Within the drum or oil vessel, 6, there are vertical pipes, 24, 25, which constitute
downward extensions of the inner oil pipe, 8, and the outer air pipe, 7 respectively,
but a connecting piece, 26, is interposed just above the top of the drum, 6, for the
purpose of introducing a screw valve, 27, for regulating the passage for the ascent
of the oil. The upper oil pipe, 8, is screwed to the connecting piece, 26, and the
upper air pipe, 7, is connected to it by a screw coupling; whilst a small passage, 28,
is provided through the connecting piece, 26, as shown in figure, 2, to allow the
air to get to the lower air pipe, 25. The pipes, 24, 25, extend down to the middle
of the bottom of the drum, 6, and this bottom is convex, or raised at the middle so
that sediment in the oil may pass to the sides. The lower air pipe, 25, is made to
serve as a tensional stay between the bottom and top of the drum, 6, its upper end
being screwed into a short tube or ring, 29, serving as a nut and connected to the
piece, 26, by a screw coupling, 30, whilst its lower end which passes through the
bottom of the drum has a cup shaped nut, 31, screwed upon it. A larger pipe, 32,
is placed outside of the pipe 25, to act as a strut, its ends bearing upon the inner
surfaces of the top and bottom of the drum. Holes are formed within the drum
through the pipes, 32, 25, near their top and bottom ends, those at the top being to
allow egress to the air to press on the top of the oil, and those at the bottom being
to allow the oil to get to the innermost or oil pipe, 24, which has holes formed
near its lower end to admit the oil. A perforated shield or strainer, 33, is placed
round the lower ends of the pipes to keep sediment from choking the perforations
of the pipes. When the compressed air is freshly turned on at any time a con-
siderable portion of it passes down to the lower end of the pipe, 25, and entering
the drum through the bottom holes passes up through the oil and drives sediment
away from the strainer, 33, thereby facilitating the passage of the oil to the oil
pipe, 24, and thence to the burner.
In the modifications of the connecting piece, 26, shown in figures, 3, and 4, the
spindle, 27, of the screw valve is entered downwards from the top, and the nozzle
or part, 34, to which the air pipe, 7, and oil pipe, 8, are connected are formed at 5
one side, in inclined and horizontal positions respectively in the two modifications.
Having now particularly described and ascertained the nature of our said
Invention and in what manner the same is to be performed, we declare that what
we claim is
1. The combination of parts constituting our improved spray lamp substantially 5
as shown in the accompanying drawing and hereinbefore described.

page_text: 2. In a spray lamp working with compressed air, the providing of apparatus
substantially as herein described for separating moisture from the air substantially as
herein before described.
3. In a spray lamp working with compressed air, the providing of a vessel or
combination of tubes placed so as to be heated by the flame and connected to the
other parts so that the air first passes through it and becomes heated and next
entering the air pipe which has within it the oil pipe passes downwards as well
as upwards therein so as to heat the oil pipe and the ascending oil substantially
as hereinbefore described.
