page_text: I LUCY ROLLASON of 21 Edgbaston Street Birmingham in the County of
Warwick Lamp Manufacturer do hereby declare the nature of my said invention
to be as follows:-
This invention has for its object improvements in lamp burners and particularly
refers to the ones used for mineral oils such as paraffin and other light volatile oils
where the oil vessel or reservoir is placed above the burner in order that the oil
máy gravitate thereto such for instance as the hanging lamps used for out door
purposes.
Such lamp burners have hitherto required more or less packing either of cotton
wire gauze or other material to prevent the too free flow of the oil but by my
invention the necessity for packing is entirely avoided in the following manner.
The oil gravitates from a vessel above the burner and is cut off therefrom by a
cock or tap in the usual manner. This supply pipe then proceeds horizontally to
the outside frame of the burner where it rises along a vertical or nearly vertical
passage and then travels along a pipe some considerable distance above the burner
and its guard plate is quite detached from the said guard or cover plate. The oil
then travels down the other side of the frame and along a horizontal. passage
under the burner and escapes upwards to the burner frame through a very fine
vertical opening therein producing a very large and most brilliant flame.

page_text: Improvements in Lamp Burners.
I LUCY ROLLASON of 21 Edgbaston Street Birmingham in the County of
Warwick Lamp Manufacturer 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:-
This invention has for its object improvements in lamp burners and particularly
refers to the ones used for mineral oils such as paraffin and other light volatile oils
where the oil vessel or reservoir is placed above the burner in order that the oil
may gravitate thereto such for instance as the hanging lamps used for out door
purposes.
Such lamp burners have hitherto required more or less packing either of cotton,
wire, gauze or other material to prevent the too free flow of the oil but by my
invention the necessity for packing is entirely avoided in the following manner:
The oil gravitates from a vessel above the burner and is cut off therefrom by a
cock or tap in the usual manner. This supply pipe then proceeds horizontally to
the outside frame of the burner where it rises along a vertical or nearly vertical
passage and then travels along a pipe some considerable distance above the burner,
and its guard plate is quite detached from the said guard or coverplate. The oil
then travels down the other side of the frame and along a horizontal passage under
the burner and escapes upwards to the burner frame through a very fine vertical
opening therein producing a very large and most brilliant flame.
In order that my invention may be clearly understood and more easily carried
into practice I have appended hereunto a sheet of drawings upon which I have
illustrated one of my lamps in vertical section in such a manner as to shew the
various passages distinct to anyone able to manufacture them.
:
Turning now to the said drawing A is the oil vessel or reservoir from
which the oil gravitates to the lamp burner B through the passage C which is
commanded by the cock D which regulates or cuts off the supply as may be
needed. The oil or spirit issues at 61 immediately under the dome or bonnet 6³
and in burning the flame extends and envelopes the burner so thoroughly as to
beat the cross bar b³ as also the upper part of 6 and 66 through which the oil
passes namely up c¹ along c³ down c³ during which time it is highly rarefied and
it then issues at 61 aforesaid. The set pins 1, 2, 3, 4, 5 are for the purpose of
stopping up the passages after they are drilled or bored out and the screw
handle E commands the very fine outlet passage 61 for drilling cleaning and
examination. The part B is generally cast in brass solid and the passages drilled
out as before mentioned but I do not confine myself to any particular metal in
their manufacture,

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 improvements in lamp burners in which the oil passes along the passages
as herein indicated is such a manner as to be thoroughly heated and highly
rarefied before escaping at the passage b¹ to be burned substantially as herein
forth.
