I, EDMUND FORD HULSE of 203 Padgate Lane, Warrington, in the County
of Lancaster, Engineer, do bereby declare the nature of this invention to be as
follows:
: I
This invention relates to oil lamps and stoves and its object is to diminish risks
of explosion and at the same time to secure a greater efficiency.
In a lamp constructed according to my improvements I employ a flat wick or flat
wicks which, or each of which, is enclosed within the lamp by a wick casing at the
bottom of which there may be an orifice for the admission of oil to the wick. This
wick casing is constructed to admit the wick freely, and extends to nearly the
bottom of the lamp reservoir, and the oil admission orifice is arranged to be closed
when the wick is turned down, so as to prevent the further admission of oil to the
wick. This closing of the oil inlet may be effected by a downward extension of

of lamp, I prefer to employ the metallic strip, which is arranged to come between
the two wick pinions and thus act as a guide. In the better class of single wick
lamps and in duplex lamps, I prefer to employ a wick carrier consisting of a
flattened tube, fitting upon the wick and within the wick casing, and provided with
indentations teeth perforations or the like with which the teeth of the wick pinions
may engage, in the manner of a rack. In this case also, I prefer to employ a
special form of wick which is thicker above the wick carrier than elsewhere. Such
a wick may be constructed by weaving it with two warps both of which are woven
into the wick at the part where it comes above the wick carrier, and one of which
is cut away at the other parts of the wick; but other devices for securing the
different thicknesses may be adopted.
In duplex lamps the extinguishing tumbler which is sometimes employed, with
single wick lamps is inapplicable. To obviate. this defect, I employ fixed rockers
on the sides of the wick holders and rest the tumblers upon the rockers, in
substitution for the loose rockers of the single wick lamp.

To facilitate the insertion of the wick into the wick carrier may construct it
with a longitudinal hinge along one edge, so that it may be opened flat. for the
reception of the wick, and be closed after its insertion. Alternatively, I may make
the wick-carrier in halves, by longitudinal division, and connect them together., by
various means, such as by clips or catches, by flattened external tubes, by adapting
one half to slide longitudinally within the other and the like.

I, EDMUND FORD HULSE of 203 Padgate Lane, Warrington in the County
of Lancaster, Engineer, 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:—
This invention relates to oil lamps and stoves and its object is to diminish risks
of explosion and at the same time to secure a greater efficiency.
A
In a lamp or stove constructed according to my improvements I employ a flat
wick or flat wicks, which or each of which is enclosed, within the oil reservoir, by
wick casing at the bottom of which there may be an orifice for the admission of oil
to the wick. This wick casing is constructed to admit the wick freely, and extends
to nearly the bottom of the reservoir, and the oil admission orifice is arranged to
be closed when the wick is turned down, so as to prevent the further admission of
oil to the wick. This closing of the oil inlet may be effected by a downward
extension of the wick carrier, or of a metallic strip attached to the wick.
In the
cheaper forms of lamp, I prefer to employ the metallic strip, which is arranged to
come between two wick pinions and thus act as a guide. In the better class of
single wick lamps, and in duplex lamps, I prefer to employ a wick carrier
consisting of a flattened tube fitting upon the wick and within the wick casing, and
provided with indentations teeth perforations or the like with which the teeth of
the wick pinions may engage in the manner of a rack and pinion. In this case
also I prefer to employ a special form of wick which is thicker above the wick
carrier than elsewhere.
To facilitate the insertion of the wick into the wick carrier, I may construct the
carrier in halves, by longitudinal division, and connect them together by various
means such as by clips or catches or preferably, by adapting one half to fit or slide
longitudinally within the other half.
The accompanying drawings illustrate a lamp constructed to embody my
improvements and will be hereinafter described.
Figure 1 represents a vertical transverse section, a part of the reservoir being
broken away.
Figure 2 shews sectional plan along the line x-y Figure 1.
Figure 3 illustrates in elevation and in vertical section respectively, a modified
form of wick carrier and wick.
A is the oil reservoir. B is the wick casing, fixed in the burner plate C and
provided at the bottom with an orifice D through which the oil can enter.
E indicates teeth formed upon one edge of each wick carrier F, these teeth being
engaged with the teeth of the pinions G. H is a block or stop at the bottom of
the wick carrier constructed to close the orifice D when the wick is turned down
and thus cut off the further supply of oil.
J is the burner dome.
The lamp illustrated by Figures 1 and 2 is of the duplex type, but my
improvements may equally and similarly be applied to a single wick lamp or to
a stove. There is a separate wick casing B for each wick, fixed in the burner
plate C. This casing consists of a flattened tube open at the top and closed at the
bottom, of such a cross section that the wick W and its carrier F can slide freely
therein. Through the bottom of the casing one or more openings D is or are
formed for the admission of oil to the wick. Each wick carrier F is a similar
flattened tube fitting upon each wick and capable of sliding within the casing B,
and has a rack cut or produced upon its edge.
At the bottom of the wick carrier there is a part or block H which may be
constructed of leather corresponding with the openings formed in the bottom of
the casing B. When the wick is turned down as far as it will go, the part H will

The flame is thus safely and effectively extinguished by the act of turning down
the wick. Also, since the only passage from the outside of the burner to the
interior of the reservoir is through D, below the surface of the oil, an explosion
such as may be caused in common lamps by blowing down the lamp chimney to
extinguish the flame, is impossible of occurrence.
Instead of employing the closed wick carrier F Figures 1 and 2, I may employ
as carrier a single metallic strip F' Figure 3, to which the wick may be secured by

points or teeth, as indicated by the sectional view.
there is a block H' as in the closed carriers, to close the hole D in the bottom of
the wick casing. The wick may be lifted and lowered by two pinions G G one on
each side of the strip F' engaging with the substance of the wick W or by a.
single pinion engaging with teeth or recesses formed in or upon the strip F.
When two pinions are used, as shewn, the strip between them acts as a guide.
of
The wick may be of the same substance throughout, but I prefer to make that
part of it which is above the wick carrier, that is to say from the point p upwards,
greater thickness than the lower part. This may be accomplished by either
adding to the original wick a short length of similar wick of each side, or upon
one side only, and stitching them together. Or such a wick may be produced
in the loom by weaving into the wick alternately for example, two and four warps,.
and afterwards cutting away the warps which are not woven in.
The wick carrier and casing are so constructed as indicated by the drawings,.
that when the carrier with the wick therein is turned down into its lowest position,
the casing is as nearly as practical filled thereby, so that there cannot be any
accumulation of oil within the casing.
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 :-
1. In a flat-wick oil lamp or stove, the construction combination and arrangement.
of a flat wick casing having a passage or passages at its lower end for the admission
of oil and a wick carrier capable of being raised and lowered within the casing and
having a block or the like adapted to close the oil admission orifice or orifices.
when lowered, the casing being of such form and dimensions that it is
practically filled by the wick and wick carrier when turned down, substantially
as illustrated by the
as and for the purpose hereinbefore described and
accompanying drawings.
2. In a flat-wick oil lamp or stove, a wick carrier consisting of a single strip
having a block or extension at its lower end, in combination with a wick casing
having au oil inlet or oil inlets adapted to be opened and closed by the block or
extersion on the carrier, constructed and arranged substantially as and for the
purpose hereinbefore described and as illustrated by the accompanying drawings.
