Improvements in Central-draft Lamp Burners.
I, SAMUEL SIDNEY BROMHEAD of 97 Newgate Street, London, Patent Agent
(a communication) 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 :-
The object of my invention is to provide a lamp burner of the type known as
Central-draft, of simple and cheap construction, of such form that the gallery or
portion of the burner supporting or carrying the chimney, may be raised or lifted
up so as to permit of the lighting or extinguishing of the wick of the lamp without
the removal of the chimney itself, and this I accomplish by means of the construc-
tion, combination and arrangement of the several parts shown and described in the
following Specification of which the accompanying drawing forms a part, wherein
similar letters of reference designate like or equivalent parts wherever found
throughout the several views, and in which :—
Fig. 1 is a side view in elevation of a central-draft lamp provided with my new
and improved form of burner, the burner being shown in central vertical section ;
Fig. 2 is a top-plan view of such burner removed from the font ; while
Figs. 3 and 4 are vertical sectional views from different directions of the outer
and upper portion of such burner; the chimney gallery in Figs. 1, 3 and 4, being
shown in a raised position.
Referring to the drawing.
A designates the oil-font, and B the central-draft tube thereof, C the wick-
chamber, and D the burner proper. Such burner D consists of an inner imperforate
cylinder or tube E which when in position on the font A forms the outer wall of
the wick-chamber C; an outer perforated cylinder or tube F which forms the outer
air-distributor, an upper air-distributing perforated ring G which extends across
the space between the tubes E and F, and a vertically adjustable chimney-
supporting gallery H, provided with downwardly extending supporting standards I
which are secured at the bottom to a ring M. Pivoted at one side of the tube F,
near the bottom thereof, is a partially rotatable rod or shaft O provided at the
outer extending end with a suitable actuating handle or thumb-piece as shown, and
rigidly secured to this shaft within the tube F, is a forked lever N, the two ends
of which fork are connected with the ring M by pivotal connections P of suitable
form, preferably of the double-pivotal one shown.
The tube E turns outward and then upward at the bottom, and is provided in
the outer upwardly extending portion as shown at e with an outer and inner
screw-thread which serve to hold the burner in position on the oil-font, and to
hold the outer perforated air distributing tube F in place on the inner tube E, such
tube F being for such purpose provided with a suitable screw-thread e¹ and with
an inner inwardly extending steadying flange f
The ring G is preferably riveted firmly to the top of the tube F as shown at
and is provided at the outer edge with a number of suitable slots or openings h
through which pass the supporting standards I of the chimney gallery H. The
gallery H, the supporting standards I and the ring M, are preferably formed
of a single piece of sheet metal spun or stamped into the required shape,

page_text: and the standards I are preferably of considerable width and are provided with
suitable perforations as shown, which register with the perforations in the air
distributing tube F when the gallery is lowered, in such manner as to allow of
free passage of the air to the flame.
The gallery H is provided with upwardly extending chimney holding fingers
which are preferably formed integral with a ring L, such fingers passing through
suitable slots or holes in the gallery ring and the ring L being held firmly in place
by the flange K of the gallery ring being turned inward under the same, as
shown.
It will be seen that in order to lift the chimney gallery H and the chimney
supported thereby up into the position shown in the drawing, it is only necessary
to exert a slight pressure in the right direction upon the thumb-piece of the shaft O,
when the wick (not shown) lying in the wick-chamber C, may be ignited by
inserting a match between two of the standards I and between the gallery H and
air distributing ring G, when the gallery H may be lowered by a reversal of the
process, the double-pivotal connection P usually serving to prevent the weight of
the chimney forcing the gallery downward by gravity.
By constructing a lifting gallery burner in the manner shown, I am enabled to
dispense with guides and guide-rods, as it will be seen that the standards I sliding
up and down in close contact with the air distributing tube F, and the ring M,
sliding up and down in close contact with the tube E which forms the outer wall
of the wick-chamber C, will together serve to steady the gallery H when in motion,
and serve to make its ascent and descent smooth, easy, and without jerks.
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
1. A lamp-burner having a movable chimney gallery H supported by standards I
provided at the bottom with a ring M, and means for raising and lowering the
same, as and for the purposes set forth.
2. A lamp-burner having a movable chimney gallery H supported by standards I
provided at the bottom with a ring M, formed integral with one another and of one
piece of metal, and means for raising and lowering the same, as and for the
purposes set forth.
3. A lamp-burner having a movable chimney gallery H supported by perforated
standards provided at the bottom with a ring M, and means for raising and
lowering the same, substantially as and for the purposes set forth.
4. A lamp-burner for central-draft lamps, having a tube E forming the outer
wall of the wick-chamber, a ring M sliding up and down on the tube E surrounding
the same, standards I extending upward from the ring M adjacent to the air-
distributing tube F, a chimney gallery H, carried by the standards, a lever N
connected with the ring M and a shaft O connected with the lever N, all
substantially as shown and described and for the purposes set forth.
