PROVISIONAL SPECIFICATION.
Improvements in Lamps for Lighting and Heating Purposes.
We, ELIZA THORPE, formerly ELIZA RIPPINGILLE, Lamp and Stove Manu-
facturer, and WILLIAM BRANDON, Foreman, both of the Albion Lamp Company,
Aston Brook Lamp Works, Birmingham, in the County of Warwick, do hereby
declare the nature of this invention to be as follows:-
The invention has for its object improvements in lamps for lighting and heating
purposes and relates to a combination of three or four flat wicks, a central draft,
a cone common to all the flames and a spreader for deflecting the combined flames
outwards beyond the cone opening.
In carrying our invention into effect we arrange either three or four flat wick
tubes so as to form a triangle, square or other rectangular figure and we by
preference arrange the wick tubes slightly inclined towards each other from the
bottom upwards so that the wicks as they issue from the tops of the wick tubes
shall nearly or
quite touch each other. These flat wick tubes may be made in the
ordinary manner as separate wick tubes in which case they are connected together
in any suitable manner to exclude air from passing between their vertical edges
or we may form these wick tubes of two parallel slightly tapered square or
triangular tubes leaving a space between their sides of thickness suitable for the
required wicks, the inner or it may be the outer of such tubes having fixed thereto
strips of metal at the required distances apart to suit the width of wick to be
used. These two tubes are fixed together so as to retain them in their required
relative position.
Each of the wick tubes is provided with a separate wick raising pinion and such
pinions are preferably geared together so as to be operated simultaneously and
free from hack lash.
The tank has a central air tube rising from the bottom and extending by
preference above the top and fitting the interior of the combined wick tubes so as
to afford a central air current to supply the inner sides of the combined flames.
Or the air tube passing through the tank may terminate at the top of the
latter and a tube carried by and descending from the wick tubes may fit within
or around such tank air tube or the burner air tube may fit on the top of the tank
air tube.
A basket is fitted around the outside of the wick tubes to regulate the supply
of air to the exterior of the flames and a cone is supported on such basket or
otherwise to conduct the outer air current against the outside of the flames.
A flame spreader of triangular, square or other rectangular form to suit the
arrangement of the wick tubes is supported by a perforated tube or basket prefer-
ably of like form and so arranged that all the air rising through the central air
passage must pass through such perforated tube or basket to the flames. Or in
lieu of using a perforated tube or basket as above described a solid diaphragm or
deflector may be inserted near the upper end of the central air space, and of such.
proportions as to leave a passage all round the same to direct air to each of the
flames.
By these means the combined flames will be provided with the necessary inner
and outer air currents and they will be spread or deflected outwards from above
the cone

page_text: In combination with such form of lamp we employ a chimney the lower part
of which is of larger area than the upper and we form the body or frame of the
chimney of metal but we apply to each side of the lower part and if desired the
upper part thereof a sheet of talc or mica for the passage of light.
It will be evident that our invention is equally applicable to other numbers of
wick tubes arranged in a somewhat similar manner to that above described but the
employment of more than four is undesirable on account of difficulty and expeuse
of manufacture.

Improvements in Lamps for Lighting and Heating Purposes.
We, ELIZA THORPE formerly ELIZA RIPPINGILLE, Lamp and Stove Manu-
facturer and WILLIAM BRANDON, Foreman, both of the Albion Lamp Company,
Aston Brook Lamp Works, Birmingham, in the County of Warwick, do hereby
declare the nature of our invention and in what manner the same is to be
performed to be particularly described and ascertained in and by the following
statement :-
The invention has for its object improvements in lamps for lighting and heating
purposes and relates to a combination of three or four flat wicks, a central draft,
a cone common to all the flames and a spreader for deflecting the combined flames
outwards beyond the cone opening.
The invention is illustrated in the accompanying drawings in which
Fig. 1 is an elevation of the lamp, Fig. 2 is also an elevation but drawn at right
angles to Fig. 1 shown partly in section and with the chimney removed therefrom.
Fig. 3 is a plan of Fig. 1 with the chimney and cone removed.
Fig. 4 is a plan of the oil tank showing the central draught tube passing through
the latter.
Fig. 5 is a section of the cone,
Fig. 6 is a reversed plan of the wick tubes and wick adjusting wheels,
Fig. 7 is a detail view drawn to a larger scale showing the manner of connecting
together the inner and outer sides of the wick tubes; and
Fig. 8 is a similar view to Fig. 6 but slightly modified.
In all the figures like parts are indicated by similar letters of reference.
According to our invention we arrange either three or four flat wick tubes a so
as to form a triangle, square or other rectangular figure; in the drawings we have
represented four wick tubes arranged in the form of a square. These wick tubes a
are slightly inclined towards each other from the bottom upwards so that the wicks
as they issue from the tops of the wick tubes shall nearly or quite touch each
other.
These flat wick tubes a may be made in the ordinary manner as separate wick
tubes in which case they are connected together in any suitable way to exclude
air from passing between their vertical edges, or we may, as shown in the drawings
form these wick tubes of two parallel slightly tapered square, or it might be
triangular, tubes, leaving a space between their sides of thickness suitable for the
required wicks, the said tubes have fixed between them strips a¹ of inetal at the
required distances apart to suit the width of wick to be used which strips as shown
at Fig. 7 preferably commence at the lower edges of the wick tubes but do not
continue to the upper edges thereof.

page_text: These two tubes are also fixed together by such strips a so as to retain them
in their required relative position.
Each of the wick tubes is provided with a separate wick raising pinion b and
such pinions may be geared together in pairs as shown at Fig. 6 and operated
by two buttons & or they may be all geared together and operated by a single
button as shown at Fig. 8.
The tank has a central air tube c rising from the bottom and extending by
preference above the top and fitting the interior of the combined wick tubes a so
as to afford a central air current to supply the inner sides of the combined
flames.
Or the air tube e passing through the tank e may terminate at the top of the
latter and a tube carried by and descending from the wick tubes may fit within
or around such tank air tube e as described in Specification of Patent 23102 of
the year 1894, or the parts may be so constructed that the burner air tube may
fit on the top of the tank air tube as described in Specification of Patent No. 12601
of the year 1895.
A basket d is fitted around the outside of the wick tubes a to regulate the supply
of air to the exterior of the flames and a cone e is supported on such basket d
or otherwise to conduct the outer air current against the outside of the flames.
In the drawings the cone e is represented as hinged to the basket d..
A flame spreader f of triangular, square or other rectangular form to suit the
arrangement of the wick tubes is supported by a perforated tube or basket g
preferably of like form and so arranged that all the air rising through the
central air passage e must pass through such perforated tube or basket to the
flames.
The perforated tube or basket g as shown in the drawing is supported by
strips of metal fixed to the central draught tube c' across the corners thereof.
In lieu of using a perforated tube or basket g as above described a solid
diaphragm or deflector may be inserted near the upper end of the central air
space and of such proportions as to leave a passage all round the same to direct
air to the inner side of each of the flames as will be readily understood.
By these means the combined flames will be provided with the necessary inner
and outer air currents and they will be spread or deflected outwards from above
the cone.
In combination with such form of lamp we employ a chimney as represented by
the broken lines in Fig. 1 the lower part of which is of larger area than the upper
and we form the body or frame of the chimney of metal but we apply to each side
of the lower part and if desired the upper part thereof a sheet of talc or mica for
the passage of light.
It will be evident that our invention is equally applicable to other numbers of
wick tubes arranged in a somewhat similar manner to that above described but the
employment of more than four is undesirable on account of difficulty and expense
of manufacture,
We would here remark that we do not claim the various parts herein described
separately considered.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed we declare that what we
claim is :-
1. In lamps for lighting and heating purposes the construction of a multiple
flat wick burner with three or more flat wick tubes, provided with a central air
draught, a cone enclosing all the wick tubes and a spreader or deflector for
spreading the combined flames outwards beyond the cone substantially as herein
shown and described.
2. In lamps for lighting and heating purposes, the combination of three or more
flat wick tubes and pinions, a basket of perforated or reticulate material surrounding
the wick tubes, a cone enclosing the upper parts of the wick tubes, a central air

page_text: tube passing through the oil tank and communicating with the space formed by
the inner sides of the wick tubes, a perforated or reticulate basket or screen or
a deflector within the upper part of the central air space, a spreader or deflector
above the cone and a chimney preferably contracted at its upper part substantially
as herein shown and described.
3. In lamps for lighting and heating purposes the peculiar combination and
arrangement of parts substantially as herein shown and described.
