IMPROVEMENTS IN LAMPS AND APPARATUS CONNECTED THEREWITH, SPECIALLY USEFUL FOR MAGIC LANTERNS AND DISSOLVING VIEWS
Year: 1880

page_text: LETTERS PATENT to William Charles Hughes, of Hoxton Street, in the County
of Middlesex, for an Invention of "IMPROVEMENTS IN LAMPS AND APPARATUS
CONNECTED THEREWITH, SPECIALLY USEFUL FOR MAGIC LANTERNS AND
DISSOLVING VIEWS."
PROVISIONAL SPECIFICATION left by the said William Charles Hughes
at the Office of the Commissioners of Patents on the 28th August 1880.
WILLIAM CHARLES HUGHES, of Hoxton Street, in the County of Middlesex.
"IMPROVEMENTS IN LAMPS AND APPARATUS CONNECTED THEREWITH, SPECIALLY
USEFUL FOR MAGIC LANTERNS AND DISSOLVING VIEWS."
This Invention consists in part of improvements upon the Letters Patent granted
to me bearing date Sept. 5th, 1877, No. 3386.
==
In carrying out these my present improvements I proceed mainly as follows:-
In the Letters Patent above referred to the chamber containing the wicks in the
lamp is enclosed with a glass of a circular or conical form.
These glasses do not allow of sufficient contraction and expansion, and are
liable to crack and break. To obviate these objections, in place of the blown an-
nealed glass being circular or conical, I cut or form this blown annealed glass
into parts which are fitted to or in doors having a spring or other arrange-
ment, whereby when the doors with the pieces of glass are brought in position
against the hood the glass is fitted tight against same, and thus contraction and
expansion is allowed for, and the liability of the glass cracking or breaking is
overcome. The glass must be blown and annealed and in shape so as to fit in the
doors and against the hood. For dissolving views I arrange the lamps one above
the other on a stand, said stand being so formed as to hold the lamps in position,
and between the spaces between the lanterns channels are arranged to allow cool
air to pass between the lanterns. The lower lamp or lamps when arranged in this
form have the chimneys curved to allow the hot air and gas to flow out without
coming in contact with the lamp next above. The cisterns to each lamp for
containing the oil when the lamps are arranged for dissolving purposes are arranged
outside to keep the contents cool. The lamps can be arranged single, or side by
Bide if required, for the above purposes.

WILLIAM CHARLES HUGHES, of Hoxton Street, in the County of Middlesex.
"IMPROVEMENTS IN LAMPS AND APPARATUS CONNECTED THEREWITH, SPECIALLY
USEFUL FOR MAGIC LANTERNS AND DISSOLVING VIEWS."
This Invention consists in part of improvements on Letters Patent granted to
me, dated Sept. 5th, 1877, No. 3386. In the Letters Patent above referred to the
chamber containing the wicks in the lamp is enclosed with a glass of a circular or
conical form. The glasses do not allow of sufficient contraction and expansion, and
are liable to crack and break. To obviate these objections, in place of the blown
annealed glass being circular or conical, I cut or form this blown annealed glass
into parts, which are fitted to or in doors having a spring or other arrangement,
whereby when the doors with tho pieces of glass are brought in position against
the hood the glass is fitted tight against same, and thus contraction and expansion
is allowed for, and the liability of the glass cracking or breaking is greatly over-
come. The glass must be blown and annealed and in shape so as to fit in the doors
and against the hood. For dissolving views I arrange the lamps one above the
other on a stand, said stand being so formed as to hold the lamps in position, and
between the lanterns channels are arranged to allow cool air to pass between the
lanterns. The lower lamp or lamps when arranged in this form have the chimneys
curved to allow the hot air and gas to flow out without coming in contact with the
lamp next above. The cisterns to each lamp for containing the oil when the lamps
are arranged for dissolving purposes are arranged outside to keep the contents
cool. The lamps can be arranged single, or side by side if required, for the above
purposes.
In order that it may be fully understood how my improvements are to be carried
out in practice I will now proceed to further describe same by reference to the
Fig. 1 Bows & hood of a lamp with the doors carrying the sections of glass.
Fig. 2, view of section of glass.
Fig. 3, side elevation of stand.
Fig. 4, front elevation.
In Fig. 1A is the hood, which can be formed of any suitable shape and sizo,
same having attached thereto by hinges doors B having openings in same, in which
doors the sections of glass C are held or placed. On said door, at top and bottom,
are fitted springs, which, when the doors with the glass are pressed into position
against the hood, the springs press the glass close against the hood. The section of
glass is generally put on both doors, but it is only necessary to put same on the
front, the back being fitted with talc, and when tale is used the reflector of the
lamp can be placed inside the hood if necessary. The stand shown in Figs. 3 and 4
is for carrying the lanterns, the lower one resting on D and the upper one on E.
Above the lower lantern channels or ventilating openings F are used, and the
heated products of combustion of the lower lamp or lamps are carried off by bent
or curved chimney G, shown in Fig. 1. The channels or ventilating openings F
allow cool air to flow between the lanterns. This stand may be constructed to hold
more than two lanterns above the other, the channels or ventilating openings being
supplied between same, and the lower lantern being provided with the bent or
curved chimney, the top lantern having a straight one. The lanterns, when two

page_text: or more are arranged on a stand, are each supplied with cistern outside the wick
tubes instead of underneath. The top lantern, when used on the stand or by itself,
can have the oil cistern in the ordinary way underneath. In consequence of
the peculiar formation of the glass for my improved lantern it enables me, if
necessary, to use four wicks.
Having now particularly described and ascertained the nature of the said
Invention, and in what manner the same is to be performed or carried out in
practice, I hereby declare that I claim the said Invention of "Improvements in
Lamps and Apparatus connected therewith, Specially Useful for Magic Lanterns
and Dissolving Views," wherein the following are peculiar and important points or
features:-
1. The formation of doors on hoods to carry sections of glass.
2. The stand having ventilating partitions or channels.
3. The sections of glass formed as shown, enabling four wicks to ¡be used if
required. All substantially as hereinbefore set forth and described.
In witness whereof, I, the said William Charles Hughes, have hereunto set
my hand and scal, this Twenty eighth day of February, in the year of
onr Lord One thousand eight hundred and eighty one.
