IMPROVEMENTS IN HALL LAMPS AND OTHER LAMPS
Year: 1885

page_text: I, WILLIAM BEAL, of Hill Street, Birmingham, Warwickshire, Lamp and Gas
Fitting Manufacturer, do hereby declare the nature of the said invention for
"IMPROVEMENTS IN HALL LAMPS AND OTHER LAMPS" to be as follows:-
My Invention relates to improvements in such hall lamps and other lamps as
have their flame protected by a lantern constructed of metal and glass or other
transparent substance.
The principal object of my Invention is to provide means whereby such lamps
can be readily taken to pieces and the lamp frame or lantern folded in a flat state
for packing and readily opened out and put together again when required; a
further object of my Invention is to provide improved means of access to the
wicks or burners of such lamps.
I will first describe my Invention as applied to a hall lamp for burning gas.
I construct a metal lamp frame or lantern of suitable shape preferably having four
equal vertical sides of rectangular shape which form a square opening at the top
and bottom of the lamp frame or lantern; the said vertical sides may be glazed in
any ordinary manner. The said vertical sides of the lamp frame or lantern
instead of being rigidly connected together as heretofore ordinarily made, are,
according to my Invention, hinged together at their meeting edges by means of
eyes formed on each through which passes along each vertical angle a tube or
wire, so that the said sides can be turned on their hinges and the lamp frame or
lantern folded in a flat state or opened out again if required. The glass part need
not be removed when the lamp frame or lantern is folded. Two of the said
vertical tubes, which are in opposite angles of the lamp frame or lantern, (which
said opposite angles are acute when the same is folded) are extended upwards and
bent over towards each other. To the top of the said tubes I prefer to connect a
boss or rosette forming the gas inlet to the lamp and lower down one or both of
the said tubes is an outlet pipe or pipes to an ordinary tap and burner at or near
the centre of the lamp. When the lamp frame or lantern is opened out the top
ends of the two tubes are connected together and to the said boss or rosette thus
maintaining the lamp frame or lantern open, but I prefer for the gas to pass only
through one of the said tubes to the burner so that the joint does not have to be
broken before folding up the lamp frame or lantern. At the bottom of the lamp
frame or lantern I provide a frame for maintaining the bottom part of the lamp
D

page_text: frame or lantern open and through which the ends of the corner tubes may pass
and I may connect the bottom frame to the lamp frame or lantern by means of
knobs screwed on to the ends of the corner tubes.
In applying my Invention to hall lamps or other lamps for burning oil I
construct and arrange the lamp frame or lantern and the means of hanging and
maintaining the same open similarly as above described for a gas lamp but I
provide in the bottom frame a lamp ring for carrying the oil lamp. The oil lamp
may be placed in the lantern by being passed upwards through the said ring and
pins may be provided at opposite sides of the lamp to pass through bayonet slots
in the ring and so maintain it in position..
'
In order that easy access may be obtained to the wicks or burners of hall lamps
and other lamps I provide fitting within the bottom frame an inner part, such
inner part being provided with vertical tubes or rods at opposite corners which
slide within the vertical corner tubes of the lamp frame or lantern; by with-
drawing the said inner part the lamp can be readily lighted and when applied as
an oil lamp the oil lamp can be readily removed for trimming or filling. I provide
a suitable catch for maintaining the said inner part in its closed position.
Instead of the lamp frame being square in plan as above described for gas and
oil lamps it may be any other figure having an even number of sides such as a
right angled parallelogram, a hexagon or octagon but the sum of the sides on one
side of the centre line of such figure should be equal to the sum of the sides on the
other side of the centre line so that the lamp frame or lantern can be folded in a
flat state as above described and the sides of the lamp frame or lantern may either
be parallel or inclined to each other.

page_text: I, WILLIAM BEAL, of Hill Street, Birmingham, Warwickshire, Lamp and Gas
Fitting Manufacturer, 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, reference being had to the
accompanying drawings and to the letters and Figures marked thereon, that is
to say :-
My Invention relates to improvements in such hall lamps and other lamps as
have their flame protected by a lantern constructed of metal and glass or other
transparent substance.
The principal object of my Invention is to provide means whereby such lamps
can be readily taken to pieces and the lamp frame or lantern folded in a flat state
for packing and readily opened out and put together again when required; a
further object of my Invention is to provide improved means of access to the
wicks or burners of such lamps.
I will first describe my Invention as applied to a hall lamp for burning gas.
I construct a metal lamp frame or lantern of suitable shape preferably having four
equal vertical sides of rectangular shape which form a square opening at the top
and bottom of the lamp frame or lantern; the said vertical sides may be glazed in
any ordinary manner. The said vertical sides of the lamp frame or lantern instead
of being rigidly connected together as heretofore ordinarily made, are, according to
my Invention hinged together at their meeting edges by means of eyes formed on
each through which passes along each vertical angle a tube or wire, so that the said
sides can be turned on their hinges and the lamp frame or lantern folded in a flat
state or opened out again when required. The glass part need not be removed
when the lamp frame or lantern is folded. Two of the said vertical tubes which
are in opposite angles of the lamp frame or lantern, (which said opposite angles
are acute when the same is folded) are extended upwards and bent over towards
each other. To the top of the said tubes prefer to connect a boss or rosette
forming the gas inlet to the lamp and lower down one or both of the said tubes is
an outlet pipe or pipes to an ordinary tap and burner at or near the centre of the
lamp. When the lamp frame or lantern is opened out the top ends of the two
tubes are connected together and to the said boss or rosette thus maintaining the
lamp frame or lantern open, but I prefer for the gas to pass only through one of
the said tubes so that the joint does not have to be broken before folding up the
lamp frame or lantern. At the bottom of the lamp frame or lantern I provide a
frame for maintaining the bottom part of the lamp frame or lantern open and
through which the ends of the corner tubes may pass and I may connect the
bottom frame to the lamp frame or lantern by means of knobs screwed on to the
ends of the corner tubes.
In applying my Invention to hall lamps or other lamps for burning oil
I construct and arrange the lamp frame or lantern and the means of hinging and
maintaining the same open similarly as above described for a gas lamp but I
provide in the bottom frame a lamp ring for carrying the oil lamp. The oil lamp
may be placed in the lantern by being passed upwards through the said ring and
"

page_text: pins may be provided at opposite sides of the lamp to pass through bayonet slots
in the ring and so maintain in position.
On the accompanying drawings Fig. 1 is a perspective view of a folding gas
lamp constructed according to my Invention; Fig. 2 is a sectional plan of the same
on line X. X. of Fig. 1; Fig. 3 represents in elevation and Fig. 4 in sectional plan
the lamp illustrated by Figs. 1 and 2 folded ready for packing; Fig. 5 represents
in front and side elevations and sectional plan one of the sides of the lamp frame
illustrated by the preceeding Figures separately; Figs. 6 and 7 illustrate parts for
use with the lamp frame illustrated by the preceeding Figures when required for
burning oil.
The same letters of reference indicate the same parts in Figs. 1 to 7, both
inclusive.
A¹, A³, A³, A' are the four rectangular sides of the lamp frame or lantern hinged
together at their meeting edges by means of the eyes a formed on each through
which passes at each vertical angle a tube which four tubes are marked on the
drawing B1, B2, B3, B4. The tubes B2, B4, are extended upwards and bent over
towards each other. To the top of the tube B2 is fixed a boss or rosette C which
at c forms the gas inlet to the burner d² by passing down the tube B2 to the outlet
pipe D on which the tap d' and burner d³ are fixed. When the four sides A¹, A³,
A³, A; of the lamp frame or lantern are opened out (see Figs. 1 and 2) the top
ends of the two tubes B2, B are connected together by screwing the connector e on
to the screwed boss f thus maintaining the top of the lamp frame or lantern open,
and the bottom is kept open by the square frame G through which the bottom
ends b of the corner tubes B1, B2, B3, B4 pass and on which the four knobs h are
screwed so as to secure the frame G to the lamp frame or lantern. By discon-
necting the tube B₁ from the rosette C and removing the frame G (see Fig. 3) the
lamp frame can be folded for packing (see Fig. 4).
When the above described lamp frame or lantern is required to be used for
burning oil the frame G¹, having an inner ring g³, (Figs. 6 and 7), is substituted
for the frame G so as to carry an ordinary oil reservoir and burner I. The oil
reservoir I can be placed in the lantern by being passed upwards (see Fig. 7)
through the ring g₁ and maintained in position (see Fig. 8) by the pins i which
pass through slots g³ in the ring G¹.
Instead of the lamp frame being square in plan as above described for gas and
oil lamps it may be any other figure having an even number of sides such as a
right angled parallelogram, a hexagon or octagon but the sum of the sides on one
side of the centre line of such figure should be equal to the sum of the sides on the
other side of the centre line so that the lamp frame or lantern can be folded in a
flat state as above described and the sides of the lamp frame or lantern may either
be parallel or inclined to each other.
Fig. 8 is a perspective view of a modified form of the lantern illustrated by
Fig. 1 adapted to a gas bracket or chandelier the sides being hinged together in a
similar manner so that by disconnecting two opposite corner tubes at the bottom
the lantern can be folded for packing as shewn in Fig. 9. Fig. 10 represents
another modified form of lantern for a gas bracket or chandelier consisting of four
oval frames K¹, K* K³, K* hinged together at their meeting edges and having the
ends of their two opposite corner tubes or wires l, l, capable of being connected
together or disconnected for folding similarly to the lantern illustrated by Figs. 8
and 9.
.
Figs. 11 and 12, 13 and 14 are diagrams illustrating examples of folding lamp
frames which are not square in plan of which Fig. 11 illustrates a lamp frame open
and forming a right angled parallelogram and Fig. 12 shews the same closed;
Fig: 13 illustrates a bexagonal lamp frame open and Fig. 14 shews the same frame
closed the sum of the sides m³, m², m³, on one side of the centre line n, n, being
equal to the sum of the sides m, m³, me on the other side of the centre line-the
sides are hinged together similarly as above described with reference to the lamp
illustrated by Figs. 1 to 10, both-inclusive.

page_text: In order that easy access may be obtained to the wicks or burners of hall lamps
and other lamps I provide fitting within the bottom frame an inner part, such
inner part being provided with vertical tubes or rods at opposite corners which
slide within the vertical corner tubes of the lamp frame or lantern; by with-
drawing the said inner part the lamp can be readily lighted and when applied as
an oil lamp the oil lamp can be readily removed for trimming or filling. I provide
a suitable catch for maintaining the said inner part in its closed position.
Figs. 15 and 16 illustrate a hall lamp for burning oil having ordinary stiff
corners and provided with my improvements for giving access to the wick.or
burner. In these Figures N is the inner part arranged to fit within the bottom of
the lamp frame Q and provided with vertical tubes or rods 01, 0³, at opposite
corners which slide within the vertical tubes P1, P2, in the corners of the lamp
frame (I have only shewn two corner tubes in my drawing but four such tubes
may be used if desired). When the inner part N (which is arranged to hold the
oil lamp R) is withdrawn (see Fig. 15) the lamp R can readily be removed for
trimming or filling and when replaced the inner part N can be pushed upwards
and re-inserted in the lamp frame Q (see Fig. 16) and the catch S will maintain
the said inner part in that position. The sliding bottom N can be applied to the
folding lamp illustrated by Figs. 1, 2, 3 and 4 similarly as above described with
reference to a lamp having ordinary stiff corners.
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:
1. Hinging together the sides of a lamp frame or lantern so that it can be folded
in a flat or approximately flat state and opened out again when required substan-
tially as described.
2. The improvements in hanging lamps hereinbefore described and illustrated by
Figs. 1, 2, 3, 4, 5, 6 and 7 of the accompanying drawings, that is to say, hinging
the sides of the lamp frame together for the purposes and as described and
represented and providing means for maintaining the lamp frame open and
allowing of its being folded when required substantially as described and
illustrated.
3. The improvements in bracket or chandelier lamps hereinbefore described and
illustrated by Figs. 8, 9 and 10 of the accompanying drawings, that is to say,
hinging the sides of the lamp frame together for the purposes and as described and
represented and providing means for maintaining the lamp frame open and allowing
of its being folded when required substantially as described and illustrated.
4. In pendant lamps the application and use of a moveable bottom inner part
for carrying an oil reservoir and burner in combination with sliding corner rods
or tubes substantially as described and illustrated by Figs. 15 and 16 of the
accompanying drawings.
