Burning
MINGHA
I CHARLES ASBURY of 216 Burbury Street Lozells Birmingham, Lamp
Manufacturer do hereby declare the nature of my said invention to be as follows:-
The lamps to which my improvement principally have reference and in connection
with which I will describe my invention are known as outside lamps such as Ship,
Street, and Platform lamps, and also to lamps for Table or domestic purposes which
burn inineral or other oils, or gas.
The object of my invention as herein after described in the construction of these,
has reference partly to the mode of manufacture, and partly to the means to facilitate
the lighting and extinguishing the same.
I will now describe my invention, which I may use in combination with certain
other improvements and embodied in the Provisional Patents No. 508 January 12th
1887 and No. 7120 May 16th 1887.
The top or reflecting part of the lamp is of a convex form with the edges turned
down, to which I attach the top bars or beads; in the centre of this convex form I
arrange a chimney, running up into the crown of the lamp; this chimney is sealed at
the top by a blank. A short distance from the top of the chimney 1 pierce a series of
holes to allow the hot air to escape, and outside the holes, I fix a cylinder somewhat
larger than the chimney, in such a manner that it prevents any direct current of air
passing through the holes in the chimney, and thus prevents a down draught; the
outer head of lamp may be of any suitable shape.
The body of the lamp I construct as follows, the body rim, top rim, and eaves, are
stamped or formed in one piece, the bars or beads are stamped or drawn in such a
shape, as that when two of them are placed together at any desired angle, they form
grooves or beads, down which the glass may be placed, thus preventing the glass from
falling either inwards or outwards; clips may be used to prevent the glass
from lifting up; I thus dispense with putty altogether.
The door is made of strips drawn or stamped in such a form that when folded or

page_text: closed over about the middle, one edge forms the outside bead and the other the
inside groove or bead down which the glass may be placed as in the body of
the lamp.
The top bars are fixed at their lower end by means of screws and nuts, the screw
being placed in the inside of the bead, in such a manner, and at such an angle, that
it passed through an eye fixed in the body, and is secured there by the nuts, in
such a manner, that the top of the lamp may be taken off for portability and
allow of close packing.
The upper ends of the bars are attached to the sloping edges of the top or
reflecting part of the lamp, the head of the lamp is made to take off as follows:
instead of the ordinary way of attaching the head to the top of the lamp, I use cast
legs or supports, which being screwed at the lower end are passed through the top and
secured in their place by nuts.
For the purpose of fixing the lamp to the frame, instead of the usual plates I put
screws, partly inside and partly outside; these screws are fitted with ornamentai
knobs, thus dispensing with nuts and forming ornamental feet for the lamp.
My improvements in connection with the burner and oil vessel is are follows:-
I make the burner in shape somewhat similar to those hitherto employed for
burning mineral oils, the body may be cast or stamped from sheet metal, but instead
of making it of a stamped shell and piercing it for ventilation, I make it as a frame,
open but with supports to carry the cone and glass holder, or gallery; the perforated
gauze or fine piercing which is used to break up the current of air before it reaches
the flame, I make in two parts, one of which is hinged or jointed to the frame or body,
in such a way that when touched it falls inwards and leaves a space or opening,
through which a taper or match may be inserted to light the wicks, (this lid or door
can be made to open outwards) the other part of the perforation may be put into the
frame loose, or it may be attached to the cone, so that it may be taken out readily for
cleaning &c.
To facilitate the extinguishing of the lamp (which has hitherto been done by means
of a ladder) from the ground and by means of a rod, I make my extinguisher in the
following way;
It is usual to place the extinguisher opposite to the spindles or windups, but I place
the lever of the extinguisher between the spindles of a Duplex burner, and to a single
burner at the side of the spindle; in a Duplex burner it is usual to place the wick
cases parallel to each other, I place them at a slight angle, so as to allow both spindles
to be of the same length, and the studs or buttons sufficiently wide apart to allow them!
to be moved easily and with greater convenience; between the two studs or thumb
pieces I arrange a clip, which is a strip of metal having a hole at each end to fit. thei
spindle, and to this clip or plate I connect the aforesaid lever, which is arranged:
directly over a stud attached to a wire, passing through the oil vessel and having at its
lower end a blank or stud of larger dimensions; this bottom stud comes over a hole
in the bottoni of the lamp or outside case, and when pushed upwards by a stick or
rod, it forces the stud up and against the lever which in its turn actuates the
extinguisher.
Instead of attaching the burner to the oil vessel in the usual way by means of a
screw or bayonet lock Joint; I. make my attachment in the following way;
The body of the burner is hinged or pivoted to the Vase ring or oil vessel in such!
a manner that it forms, a lid to the Vase ring instead of being unscrewed or detached:
on the bayonet lock Joint principle.
The cone and glass holder is hinged or pivoted to an arm or support attached to the
oil vessel, in such a manner that the gallery may be lifted up, and the burner body
opened for re-filling without removing the glasses. For the purpose of securing the
burner in its proper place on the Vase ring it is fitted with a moveable collar; this:
moveable collar has a tapering projection at the edge, turned up in such a way, that
it forms a thumb bit and wedge on the outer edge of the collar; when the collar is
turned round, the wedge is forced under a small projection on the support or arm.
and thus locks the moveable collar and vase ring tightly.together..

page_text: In my improvements for increasing the power of the light and diffusing its rays,
I use a dioptric lens or cylinder, cut in two or more sections; these sections are
fitted into a metal frame, which is made to open for the purpose of removing the
burner &c.; the metal frame is secured to a stretcher or carrier which is fixed across
the lamp in any suitable way. The carrier also supports a chimney in the centre the
chimney being pinned or pivoted in such a manner that it hangs loose, so that when
the frame containing the dioptric sections is opened and the burner fitted with a short
glass chimney is put into its place, the metal chimney or stretcher comes directly on
to the top of the glass chimney and thus forms a continuous current of air; by this
means I obviate the necessity of a long chimney and make it more convenient to take
out and replace the oil vessel.
For the purpose of indicating the quantity of oil in the oil vessel I fix on to the top
a small piece of glass or other transparent through which may be seen at a glance
how much oil is in the vessel.

Improvements in the Construction of Lamps for Burning Mineral,
Vegetable, or other Oils or Gas.
I, CHARLES ASBURY of 216 Burbury Street Lozells Birmingham, Lamp Manu-
facturer, do hereby declare the nature of my said invention and in what manner
the same is to be performed, to be particularly described and ascertained in and. by
the following statement.:-
In order that this my said invention inay be more clearly understood I have
prepared drawings hereunto annexed with Figures and letters thereon to facilitate the
description, the same letters of reference indicating like or corresponding parts on
each figure where they occur.
My invention has reference principally in the improvements of outside lamps, that
is to say, Street, Ship and platform lamps (made of metal) but also applicable to lamps
employed for domestic purposes, being that class of lamp which burns or consumes
mineral or other oil or gas.
..
I will describe my invention with its improvements as relating to street lamps aided
by the accompanying sheets of drawings
Fig. 1 is a view in elevation of the lamp in its entirety.
Fig. 2 is a plan view of top of same.
Fig. 3 a view in elevation of crown with outside top removed.
Fig. 4 views of sections of bars or beading separate and joined, full sized.
Fig. 5 views of sections of top rim and body rim full size.
Fig. 6 elevation and plan of inside loose or swinging chimney, showing method of
attachment (3 inch scale).
Fig. 7 a view in elevation, full size, of oil container and burner, showing methods
of opening, lighting and extinguishing.
Fig. 8 is a plan view of same.
a is the top part of lamp (sheet 1) Figs. 1 and 2; bare the cross bars or beads,
(sheet 2) Fig. 4, full size. c is the metal chimney. Fig. 3 (sheet 2) passing into the
crown d; this said chimney c is closed or sealed at the top shown at c' but
provided with the holes or piercings 2 through which the hot air when the lamp
is lit and in use, escapes. c¹ is cylindrical in form arranged over, partly secreting
the holes or piercings c² sufficient to prevent any direct current of air passing through
the said holes and a down draught which is of great importance. a¹ is the body
of the lamp. a a³ a are respectively the top rim, the eaves and body rim, these are
stamped or formed as shown in the section full size. Fig. 5. (sheet 2); the bars or
beads b are drawn or stamped in the length forming an aperture in each, then cut,
and mitred and soldered together according to the angle or position required; the
said aperture holds the glass with the aid of the metal clips b².
e are strips drawn or stamped analogous to 6 forming beads for the door and
apertures for the glass. The body of the lamp is constructed with the beads as above
described for holding the glass.

page_text: The top part of the lamp a is affixed to the body a¹ by means of the loops or eyes b³
each bar having one eye soldered thereto, and each corner or angle of the body of the
lamp has a screwed nut secured in the interior at 63 so that by the employment of an
ordinary headed screw passing through the loops or eyes 63 and into the said nut and
thus being portable admits of close, packing which is a great consideration.
The bars are connected to the top or reflecting part of the lamp 6 by soldering
or other suitable means. 9 is the head of the lamp, also constructed for facility in
packing as follows. gare legs or supports applied to the bottom of and screwed
exteriorily and passed through apertures in part of the top shown g³, screwed nuts
are then employed in the interior and to the said g¹ by means of which it is
securely held.
The mode of affixing the said lamp to the frame by my improvements is as follows:
I securely connect the screwed part h to each corner of the lamp as shown in Fig. 1
A view. The knobs have holes screwed right through, so that in fixing the lamp
to the frame it is only necessary to pass the screwed parts through corresponding
apertures in the frame and engage the knobs h¹ thereon until the frame is reached and
the lamp is secure; the said Knobs are also for ornamental effect, and utility, to be
employed as feet when the lamp is removed from the frame as Fig. 1.
In Fig. 1 I show the component parts of burner to the oil container affixed to the
lamp with dioptric lens in its proper working position, and in Figs. 7 and 8
(sheet 3) detaclied.
The parts forming the burner is of that class employed for burning mineral oils and
partakes somewhat of the usual shape, that part known as the body I now make as a
frame shown i and by preference in cast metal, and with supports to carry the cone j
and glass holder or gallery j. k is the gauze through which the air passes before. it
reaches the flame it is made in two parts as Fig. 7 one part being hinged or jointed
at that is to the frame or body i and in such a manner that when pressure is applied
from the outside it will fall in, with an aperture formed through which a light can
be inserted to the wicks; the other part of the gauze is shown at K2 attached to the
under or inner part of the conej but it may be also fixed in the frame i loose in either
case it can be cleaned with facility.
A difficulty has hitherto existed in the extinguishing of these outside lamps a
ladder being chiefly employed, to remedy this, I construct my extinguishing apparatus
as follows applied to a duplex burner Fig. 7 and 8. (sheet 3). The spindles or wind
i
ups of the wicks of the said burner which have hitherto been parallel to each other
which for actuating necessitated one being shorter than the other, this being
objectionable I make the said spindles of the same length and with the wick tubes /¹
diverging slightly, sufficient for the two studs or buttons n, to work on a line with
each other, as shewn in Fig. 8, between the said spindles and wick tubes " I arrange
the lever mactuated as follows, m' is a part of the said lever which 1 term a clip
having two holes and through which the spindles 1, pass both holes are somewhat
larger than the spindles to allow an amount of freedom in action and at m² it is jointed
or hinged to and in connection with the slides or extinguishers proper m³. o is a stud
and of a wire or rod passing through the oil vessel or reservoir o² in a tube 03. 0¹ is a
stud larger than o, and is arranged immediately over a hole in the bottom of the body
of the lamp a', so that when pressure is applied to ot by means of a stick or rod it will
rise and the stud o, also raising the lever m, and with it the slides or extinguishers m³
upon the wick tubé l' over and around the flame and it is then extinguished-when
the rod or stick is withdrawn the Slides m³ and lever m, Stud o, rod o¹ and Stud o
fall by their own weight to their normal position.
To a single burner that is to say a burner having one wick tube and for only one
flame I arrange the lever m and its component parts at the side of the spindle.
My mode of connecting the burner to the oil vessel or reservoir is as follows:
I arrange the burner complete to the vase ring p, by means of the Joint or hinge p¹.
The core, and glass holder or gallery -I also Joint or hinge at q, to the arm or
support q¹ which is connected also to the vase ring at 92 so that the gallery and the
burner may be lifted or raised sufficient to refill the reservoir and attend to the cotton

page_text: without the removal of the glasses. The part of burner jointed at p¹ to the vase
ring p is first closed down and then j and j¹ and secured thus. s, is a collar moveable,-
provided with the tapering projections with the thumb bit s2, when Motion is given
to the moveable.collar s, it is by. means of this thumb bit s which then engages s
under the projections and thereby firinly held.
For increasing the power of light I. use the dioptric lens t, u, is a stretcher or
carrier which is fixed across the lamp in a suitable way, and supports the metal
chimney ', which said chimney is pivotted to the stretcher u. at u² hanging loose so
that the dioptric lens t, through which passes a short glass chimney arranged to the
usual part of the burner, the Chimney' comes directly on to the glass chimney and
thus forms a continuous current of air, by this mode I obviate the necessity of a
long chimney and thus make it more convenient to take out and replace the oil
Vessel.
My mode for ascertaining the quantity of oil in the reservoir or oil Vessels 02.
is as follows:-
•
I fix the glass or other transparency in a suitable frame as v¹, the quantity of Oil
in the Vessel being seen at a glance.
Although in the above description I have confined my remarks to that class of lamp
having burners for consuming oils of the ordinary kind but by substituting other
burners with slight modifications gas can be employed with the same advantages.
The above being my said Invention I wish to say that I do not confine myself to the
precise details or arrangement of parts as shown on the accompanying sheets of
drawings, but that I hold myself at liberty to alter or modify the same without
departing essentially from my said Invention.
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 is―
The general construction combination and arrangement of parts forming the burner
and parts connected therewith the mode of filling, lighting and extinguishing the same,
the mode of fixing the glass in beads and top rim, eave, and body rim.
The mode of disconnecting the several parts to facilitate in packing. The mode of
ascertaining the amount of Oil in reservoir substantially as set forth and described in
the foregoing Specification and shewn on the accompanying Sheets of Drawings.
