page_text: We, JOHN FULLER SHALLIS, and THOMAS COOPER JOHN THOMAS, both of
54 Minories in the City of London, Engineers, do hereby declare the nature of this
invention to be as follows:-
In the specification of a former patent granted to us under date 16 August 1881
No 3564 is described a construction of lamp with a burner or burners projecting
into a combustion chamber horizontally or angularly, and the present invention
has reference to such and similar lamps and is designed to guard against the
production of smoke resulting from imperfect combustion arising from improper
regulation and consequent excessive projection of the wick.
Heretofore in such lamps it has been usual to use (for each burner) a single wick
extending at one end into the oil in the reservoir and projecting at the other end
beyond the wick tube of the burner, but according to the present invention separate
wicks are used placed at or approximately at right angles to one another and one
of which dips into the oil in the reservoir, whilst the other extends from it to and
through the burner tube, means such as a presser of any suitable construction being
employed to retain the one wick in contact with or juxtaposition to the other.
Thus it will be understood that only the one wick is consumed, the other being
employed simply to convey oil to it from the reservoir. By this arrangement
burner wicks of uniform length may be employed and they may be stiffened with
inflammable material such as paraffin wax. One arrangement of presser is in the
form of a plate suitably guided and provided with a rod or stem whereby it may
be raised from the upper or horizontal wick in opposition to a spring that tends
normally to keep the two wicks in contact. The presser may be provided with
a holder for the horizontal wick; and in lieu of a stem or rod for operating the
presser it may be attached to a small sliding door, or the construction of the presser
may be otherwise modified in various ways as for example instead of being a plate
it may assume the form of a lever with teeth caused to press upon the wick by a
projection upon a sliding door, and to rise from the wick under the action of
a spring when such door is opened. The arrangement may be such that the burner
wick can be inserted into its tube from the rear, the tube being provided with a
stop or stops to limit the extent of projection of the wick at the burning end.
The relative angles of the upper or burner wick and the lower or feeding wick
will obviously depend upon the arrangement of the burner.

We, JOHN FULLER SHALLIS, and THOMAS COOPER JOHN THOMAS, both of
54 Minories, in the City of London, Engineers, 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 :-
In the specification of a former patent granted to us under date 16 August 1881
N° 3564 is described a construction of lamp with a burner or burners projecting
into a combustion chamber horizontally or angularly, and the present invention
has reference to such and similar lamps and is designed to guard against the pro-
duction of smoke resulting from imperfect combustion arising from improper
regulation and consequent excessive projection of the wick.
Heretofore in such lamps it has been usual to use (for each burner) a single wick
extending at one end into the oil in the reservoir and projecting at the other end
beyond the wick tube of the burner, but according to the present invention separate
wicks or a wick or wicks and the equivalent of another wick or wicks are used
placed at or approximately at right angles to one another and one of which or one
set of which dips or extends into the oil in the reservoir, whilst the other extends
from it to and through the burner tube, means such as a presser of any suitable
construction being employed to retain the one wick in contact with or juxtaposition
to the other wick or set of wicks or equivalent. Thus it will be understood that
only the one wick is consumed, the other wick or wicks being employed simply to
convey illuminant to it from the reservoir. By this arrangement burner wicks of
uniform length may be employed and they may be stiffened with inflammable
material such as paraffin wax.
One arrangement is represented in Figs. 1 and 2 of the drawings. A modifica-
tion is illustrated in Figs. 3 and 4 and a further modification is shown in Figs. 5
and 6. In each case A is the burner wick tube and B the oil reservoir. C is a
wick or set of wicks hung upon or supported by a rod D, so that the wick ends dip
into the oil in the reservoir. It will be evident that in lieu of a wick or wicks
such as C other material (for example sponge) may be used that will by capillary
attraction draw up oil to the wick E, at one end of which combustion takes place.
The wick E is separate from the wick or wicks C or equivalent, but is kept in
contact with or contiguity to the wick or wicks C or equivalent by means of a
presser. In the arrangement illustrated in Figs. 1 and 2 the presser is in the form
of a plate F suitably guided and provided with a rod or stem G whereby it may
be raised from the upper or horizontal wick E in opposition to a spring H that
tends normally to keep the said wick in contact with the wick C.
Those parts of the lamp not expressly specified but which are shown in the
drawing will need no further description here inasmuch as they will be found to
accord substantially with our former invention.
In the modification illustrated in Figs. 3 and 4 the presser is provided with a
holder for the horizontal wick, this holder being an extension of the wick tube A
which is connected to the presser. In this arrangement in lieu of a stem or rod
for operating the presser, the small sliding door that carries the presser is provided
with a handle I.

page_text: In the arrangement illustrated in Figs. 5 and 6 the presser is in the form of a
lever J pivotted at K and provided with teeth L caused to press upon the hori-
zontal wick E by a projection M upon the sliding door N which slides in horizontal
guides O in lieu of vertical guides (as in Figs. 1 and 2 and Figs. 3 and 4). In this
case the presser may be caused to rise from the wick by the projection M striking
against the arm P when the door is opened; or this may be effected by a spring.
As will be evident, the details of construction and arrangement may be variously
modified and our invention may be applied in lamps of other forms than those
parts of which are shown. There may be more than one burner wick and the
arrangement may be such that the burner wick can be inserted into its tube from
the rear as in Figs. 5 and 6, the tube being provided with a stop or stops to
limit the extent of projection of the wick at the burning end.
Having now particularly described and ascertained the nature of this invention,
and in what manner the same is to be performed, we declare that what we
claim is:-
In a railway carriage or other lamp,
1. The use of a wick or wicks or equivalent extending into the oil reservoir and
serving to draw up oil by capillary attraction in conjunction with a wick (or wicks)
arranged at an angle to the first named wick or wicks or equivalent substantially
as described and for the purpose specified.
2. In conjunction with a wick or wicks or equivalent extending into the oil
reservoir and a wick arranged at an angle thereto, the use of a presser for keeping
the two wicks or wick and equivalent in contact or juxtaposition, so that oil may
be conveyed from the reservoir by the one wick or set of wicks or equivalent to
the other wick to support combustion.
3. The arrangement of parts substantially as described with reference to and
illustrated in Figs. 1 and 2 of the drawings for supporting wicks at an angle to
one another so that one dips into the reservoir and serves to convey oil to the other
as above set forth.
4. The arrangement of parts substantially as described with reference to and
illustrated in Figs. 3 and 4 of the drawings for supporting wicks at an angle to
one another so that one dips into the oil reservoir and serves to convey oil to the
other as above set forth.
5. The arrangement of parts substantially as described with reference to and
illustrated in Figs. 5 and 6 of the drawings for supporting wicks at an angle to
one another, so that one dips into the reservoir and serves to convey oil to the
other as above set forth.
