Specification Accepted, 27th Sept., 1887.
Is an elevation of same.
Figs. 6 and 7 show portions of the outer and inner wick tubes respectively.
Fig. 8 shows two views of the bent metal spring plate for receiving the ends of the
cog wheel spindles.
Fig. 9 shows two views of a modified form of same.
As shown in the drawings the body or oil reservoir A, which is of thin metal is
placed on a separate vase shaped metal base B, having perforations a which permit air
to pass through to a central tube C, secured in the reservoir A, and which constitutes
passage straight through to the burner, but it will be evident that the lamp may be
nade in one part, air being taken into the central hole through the foot thereof, or the
D

page_text: lamp may he mounted on feet. This tube C, may have brazed or secured thereon a
ring or thickening piece b. Over this tube C, is slid a tube D, extending to the
bottom of the reservoir A, the upper portion of same having one or more slots d', as
shown in Fig. 7. The purpose of the ring b, on tube C, is to enable a closer fit to be
made between the tubes. The wicks employed are flat ones and may be one, two, or
more in number. As shown, two flat wicks E, E, are employed. They may be of any
length and are held between the tube D, and a shorter tube F, of larger diameter
which surrounds same. This tube F, at its lower end is widened or flared as shown to
permit of the easy introduction of the wick, and is soldered, brazed, or otherwise
secured at the point d, to the cup shaped piece F', which carries a screw threaded
portion or ring e, screwing into a corresponding female thread on the interior of the
casing A. Above this point the casing is expanded into a cup shaped forin as shown
at A, which serves to hold and prevent any slight overflow of oil which might occur
from capillary attraction through the screw thread or any which might run over outside
the burner. The tube F, as will be seen on referring to Fig. 6, has on its interior two
ribs or fins, which serve as guides for the wick. On their upper ends they are enlarged,
the two projections", so formed, fitting into the slots d', d', of the inner tube D, and
serving to hold same in position. The number of these fins or ribs is varied according
to the number of flat wicks employed. If desired, this arrangement may be altered,
the fins being formed on the inner tube D, while the slots are in the outer tube F.
Upon the outside of the tube F, at a point outside of the reservoir A, is soldered or brazed
a bent spring plate G, as shown in Fig. 3, into the holes in the free ends of which are
placed the ends of the spindles H, which carry teeth h, or one, two or more cog wheels
as shown in Fig. 8 which work in slots in the tube F, and serve to raise and lower the
wicks. The other ends of the spindles are then sprung into slots i, i, formed on the
edge or rim of the cup shaped piece F, when they are in a position to be easily revolved
by the ordinary milled heads or discs j, the spring plate G, holding, them firmly in
position, while they can be readily removed for cleaning or to facilitate the examination
of the lamp. To increase the "spring" of the plate it may be easily squeezed up at the
bends by pincers. In Fig. 9 is shown a modified form of this plate G, which may be
sometimes convenient to use. The centre part is soldered to the tube F, while the
ends are separate and are adjustable by means of the screws, thus enabling the
pressure on the spindles H, to be regulated. To cover in these spindles a cap K,
Fig. 4, is placed over them and fits into the cup shaped piece F¹, slots 1, 1, being
provided to allow the spindles to pass through.
Above this cover.
.K, and surrounding the upper portion of the wick tubes is a
perforated casing L, which when in place serves to admit air to the outside of the
wick. This slides on the outer wick tube F, and is held in place by the ring L', which
as shown in Fig. 2, is distorted at the points I, when it slides over and grips the
tube F. This ring L', is held in place by the wings or pieces m which are brazed or
secured to it at the points L, and to the annular flame guide L³, the whole of these
parts being secured to, or being one, with the casing L. The lower portion of the
Hame guide L³, may be perforated if desired and may carry a ring n having
corresponding perforations which may be moved round to cover up the openings in
the part L³, when it is not desired that air should pass through them. I do not confine
myself however to this construction of the casing L, as any other which is found to be
suitable may be used. Centrally placed in the upper part of the air tube C, is a short
removable tube M, having wing pieces o,(Figs. 5 and 5) the shoulders or projections o 1,
on which rest on the edge of the tube C, and hold it in position.
This tube M, has a deflecting flange M', formed thereon and also carries a second
removable deflecting cap N, which as shown is concavo-convex in shape, but it may
be of any other form depending upon the shape it is desired to give to the flame.
This cap is held in position by metal webs p, the projecting shoulders p' of which, rest
on the flange M', and hold the cap in position.
To introduce the wicks into the tubes, the outer tube F, is unscrewed from the oil
reservoir at the point e, thus enabling all of the burner portion of the lamp to be
lifted out, leaving an opening through which the reservoir is filled with oil, when the

page_text: flat wicks which may be of any convenient length are pushed up between the
tubes D and F, the metal strips f, serving as guides while this is being done. The
turning of the wheels or teeth on the spindles H, will raise them to the top of same.
The wick can be easily controlled and regulated by raising or lowering one or both of
the parts.
The operation of the lamp is as follows:-
Air enters through the openings a in the base (or through a central air tube in the
foot or stand as indicated by dotted lines and in this case the stand may be made with
feet as indicated) and passes up through the central tube C, past the wing pieces o, of
the removable tube M, as indicated by the arrows and so to the interior of the flame
formed at the end of the wick; a current of air also passes up the interior of the
tube M, past the wing pieces p, of the removable cap N, as indicated by the arrows
where it is heated and passes in that state on to the interior of the flame, the cap
deflecting it and causing the flame to be enlarged and increased in brilliancy."
Air to the outside of the flame is supplied as is usual through the perforated
casing L. It passes up as indicated by the arrows both between the tube F, and the
ring L', and also between the latter and the flame guide L³, the current passing to the
outside of the flame and between it and the glass chimney."
Having now particularly described and ascertained the nature of my said invention,
and in what manner the same is to be performed, 1 declare that what I claim is :-
1st. In a lamp, the combination of a central air passage C, tubes D and F, with
one or more flat wicks E, substantially as shown and for the purposes set forth.
2nd. In a lamp, the combination of tube C, with internal tube M, having deflecting
flange M', and cap N, all substantially as and for the purposes set forth.
3rd. In a lamp the combination of spindles H, having cogs or teeth h, with
adjustable end bearing spring plate G, cup shaped piece F, provided with slots
substantially as described and for the purposes set forth."
4th. In a lamp, the cup shaped piece A', surrounding the part F, substantially as
and for the purposes set forth.
5th. In a lamp, the cup shaped piece or protecting cap K, serving to cover the
cog wheels and hold them in place, substantially as set forth..
6th. The. general construction and combination of parts forming the improved
lamp, substantially as described and illustrated in the accompanying drawings.
Dated this 24th day of August 1887.
