IMPROVEMENT IN LAMP BURNERS
Year: 1884

page_text: PROVISIONAL SPECIFICATION.
I, WILLIAM HARVIE, of Nº 222 Broomieław, Glasgow, in the County of Lanark,
North Britain, Lamp Manufacturer do hereby declare the nature of tho said
invention for AN IMPROVEMENT IN LAMP BURNERS to be as follows :—
This Invention, which relates to an improvement in Lamp Burners, is especially
adapted for the burners used in Ship and other Signal Lamps, such for example as
the Signal Lamps described in the Specification of the said William Harvie,
N° 1493, A.D. 1868.
The object of the present Improvements is to cause the air supplied to the
wicks of duplex or triplex wick-burners to impinge directly on the flames thereof
and which is effected by the piece of apparatus constituting this Invention,
namely, a cover hinged at one side to the burner so that it may be raised or
lowered after the manner of a lid, the underside of the central member and the
outer member of each division of the lid corresponding to each wick being inclined
and thereby giving the air the requisite direction towards the flame.
These improvements are especially applicable to Lamps wherein Colza or
analogous oils are burnt.

I, WILLIAM HARVIE, of No. 222 Broomielaw, Glasgow, in the County of Lanark,
North Britain, Lamp Manufacturer do hereby declare the nature of my said
invention for AN IMPROVEMENT IN LAMP BURNERS and in what manner the same
is to be performed, to be particularly described and ascertained in and by the
following statement :―
My Invention, which relates to an improvement in Lamp Burners, is especially
adapted for the burners used in ship and other signal lamps, such for example as
the signal lamps described in the specification of me the said William Harvio
No. 1493 A.D. 1868.
The object of my present improvements is to cause the air, supplied to the wicks
of duplex or triplex wick-burners, to impingo directly on the flames thereof, and
which is effected by the piece of apparatus constituting my Invention, namely, a
cover hinged at one side to the burner so that it may be raised or lowered after
the manner of a lid, the underside of the central member and the outer member of
each division of the lid corresponding to each wick being inclined and thereby
giving the air the requisite direction towards the flame.
These improvements are especially applicable to Lamps wherein Colza or
analogous vils are burnt.
In order that my Invention may be fully understood and readily carried into
effect, 1 will now proceed to describe the Drawings hereunto annexed.
Figures 1 and 2 (Sheet 1) are respectively a front elevation and a rear elevation
of a lamp having a duplex wick-burner provided with apparatus constructed
according to my present Invention.
Figures 3 and 4 are respectively vertical sections taken on the lines A Band OD,
Figure 5.
Figure 5 is a plan of the same.
Figure 6 is a horizontal section of the same taken on the line E F Figure 1.
Figures 7 and 8 (Sheet 2) are respectively a vertical section and a plan of a
lamp having a triplex wick-burner provided with apparatus constructed according
to my present Invention, the said vertical section being taken on the line O H.
Figure 8.
Figures 9 and 10 (Sheet 3) are respectively a vertical and a horizontal section of
the same the former being taken on the line I J Figure 8 and the latter on the
line K. L. (Figure 7).
Figures 11 and 12 are plans of modified portions of the lamps represented nt
Figures 1 to 10 and are hereinafter more particularly described.
With reference more particularly to the lamp represented on Sheet 1 of the
annexed drawings, that is to say, to the lamp arranged with the duplex wick-burner,
it is seen that the oil reservoir a, which is provided in the ordinary manner with
a scrowed charging plug b, having its air inlet c, (Figure 5) passing through it, is
supported in the back plate d. This back plate, d, is provided with the small glass

page_text: windows, which, together with the opening f, in the reflector g, (which is
represented in dotted lines at Figures 1, 3 and 5) admits of the wicks being
adjusted and seen at their burning points from the back of the lamp. Through
the oil reservoir a, the two rods h, pass, each being provided with three wick-
adjusting wheels i, and at their opposite ends, as a security against leakage, the said
rods pass through suitably formed glands and stuffing boxes j. The wheels i,
rotate partly within the wick-tubes k, and partly in the oil containing portion of
the vertical member 7, of the oil reservoir. This vertical member 1, has the
central tube m, passing through it, so that air may pass upwards to the burning
portion of the wicks n. At the outer sides of the wicks n, two other openings o,
through the plate p, direct the currents of air passing up through such openings
with the requisite degree of obliquity onto the outer sides of the flames burning
at the upper ends of the wicks n. The air space of which these two openings o,
form the outlets, is constructed between the outer surface of the vertical oil
chamber, and the inner surface of the casing q, to which the said chamber 6, is

soldered at its back as shewn more particularly at Figure 4.
deflection of the currents of air passing up through the central tube m, outwards
on to the flames of the two wicks n, I provide the bar r, which is hinged as a lid
at 8, (Figures 4 and 5) to the plate p, and having its surfaces, against which the-
ascending currents of air impinge, curved as shewn more particularly at Figure 3
of the annexed drawings. When it is desired to have access to the wicks n, for
trimming or for other purposes, the lid r, may be turned upwards as indicated by
dotted lines at Figure 4.
The reflector g, represented in dotted lines upon the annexed drawings is
supported in position by means of a band secured to its back, passing over the
bracket t, from which the said reflector may be removed at any desired time.
With reference to the lamp represented on sheets 2 and 3 of the annexed
drawings, that is to say, to the lamp arranged with the triplex wick-burner, the
details of the reservoir a, and vertical oil chamber L, are constructed in a manner
similar to that herein before described with reference to sheet 1, as also are parts
indicated by letters corresponding thereto. The central air tube u, of this triplex
wick-burner being necessarily of triangular or other section approximating thereto,
the plate or lid for deflecting the currents of air on to the inner sides of the
flames of the wicks is consequently of a similar shape, that is to say, its edge is
constituted of as many sides or divisions as there are wicks employed. The lid v,
therefore is formed of three divisions, and each of these divisions is so inclined at its
underside as to deflect the currents of air passing upwards through the central
tube t, against the inner sides of the flames burning on the wicks w.
supplied to the outer sides of the flames, through the openings 2, formed in the
plate y, which openings constitute the outlets from the annular air space or
chambers, formed, as in the lamp hereinbefore described, between the outer surface
of the vertical oil chamber L, and the casing q; surrounding it.
Air is
The plate or lid v, being hinged at 8, to the plate y, may be turned upwards
into the position represented in dotted lines at Figure 9, when, for trimming or
other purposes, access is required to the wicks w, and their adjacent parts, the
connection a', between the plate or lid v, and its hinge being of such shape as will
not be materially affected by the flame burning immediately below it.
In place of forming the lids r, and v, of a central piece applying only to the
inner sides of the flames, the lids may be made as shewn in plan at Figures 11
and 12, Figure 11 applying to the duplex burner shewn on sheet 1, and Figure 12
to the triplex burner shewn on sheets 2 and 3 of the annexed drawings; by means
of the lids being constructed as shewn at Figures 11 and 12 the air is deflected or
directed against both sides of the flames.
The parts of the lamp represented upon the annexed drawings and not herein-
before described, forming no part of my present Invention, need not be herein
Gurther referred to

page_text: Having now particularly described and ascertained the nature of my said
Invention and in what manner the same is to be performed, I declare that what
I claim is
The improvement in lamp burners consisting of a hinged lid having. two or more
hollowed or oblique under surfaces which, when the said lid is in its normal or
lowered position, deflects currents of air passing upwards through the central
passages m, and u, as well as through the outer passages o, and x, against the inner,
or both the inner and outer, surfaces of the flames substantially as herein before set
forth with reference to the annexed drawings.
