IMPROVEMENTS IN HURRICANE LANTERNS, ALSO APPLICABLE to OTHER HANGING LANTERNS
Year: 1883

page_text: LETTERS PATENT to Herbert John Haddan, of Kensington, Middlesex' for an
Invention of IMPROVEMENTS IN HURRICANE LANTERNS, ALSO APPLICABLE to
OTHER HANGING LANTERNS-A communication to him from abroad by Adolf
Schindler, of Schweidnitz, in the German Empire
PROVISIONAL SPECIFICATION left by the said Herbert John Haddan
at the Office of the Commissioners of Patents on the 19th January 1883.
HERBERT JOHN HADDAN, of Kensington, Middlesex, "IMPROVEMENTS IN
HURRICANE LANTERNS, ALSO APPLICABLE TO OTHER HANGING LANTERNS," a
communication to me from abroad by Adolf Schindler, of Schweidnitz, in the
German Empire,
This invention has for its object to render the interior of lanterns easily accessible
without the use of side doors. For this purpose I construct the lantern of two
principal parts, namely a lower part formed by a flanged base plate carrying the
lamp in the centre, and the upper part comprising the glass-sheets, frame, roof
and chimney of the lantern. To the outside of the base-plate and diametrically
opposite each other are secured two vertical bars extending up to or over the roof
of the lantern.
Each of these bars passes loose through a guide attached to the roof and serves
to support one end of a hoop hinged to the bar a little below the guide and bulged
outward to give room for said guide. The said hoop which in use is placed vertical
and serves to suspend or hold the lamp need only be turned down a little to allow
the upper part of the lantern to be lifted out and give access to the interior of the
lantern.
The vertical edges of the glass sheets are fixed in pairs to four specially shaped
vertical bars.
Each of the latter forms two parallel grooves each having an angle of about
45 degrees, so that the outer sides of the two grooves on which the glass panes rest,
form with each other a right angle.

by the said Herbert John Haddan in the Great Seal Patent Office on the
18th July 1883.
HERBERT JOHN HADDAN, of Kensington, Middlesex, "IMPROVEMENTS IN
HURRICANE LANTERNS, ALSO APPLICABLE TO OTHER HANGING LANTERNS," a
communication to me from abroad by Adolf Schindler, of Schweidnitz, in the
German Empire,
This invention has for its principal object to render the interior of lanterns easily
accessible without the use of side doors.
For this purpose I construct the lanterns of two principal parts, namely a lower
part formed by a flanged base plate carrying the lamp in the centre, and an upper
part comprising the glass-sheets, frame, roof and chimney of the lanterns.
In the accompanying drawing Fig 1 represents a vertical section, and Fig 2 a
plan of a hurricane lantern embodying the invention. i is the base plate fixed to the
iron ring or flange h.
To the outside of the base plate and diametrically opposite each other are secured
two vertical bars 7, extending up over the roof g of the lantern. Each of these.
bars passes loose through a guide n attached to the ring a which carries the roof g,
and serves to support one end of a hoop m hinged to the bar a little below. the
guide and bulged outward to give room for said guide. The said hoop m, which
in use is placed vertical and serves to suspend or hold the lamp, need only be turned
down a little to allow the upper part of the lantern to be lifted out and give access
to the interior of the lantern.
The vertical edges of the glass sheets fare fixed in pairs to specially shaped
vertical bars e. Each of the latter forms two parallel grooves having an angle of
about 45 degrees, so that the outer sides of the two adjoining grooves on which the
glass panes rest, form with each other a right angle. The object of this arrangement.
is to facilitate the use of glass panes of different thickness.
In the bottom i of the lamp is an aperture o through which the lamp k may be
inserted from below, without taking the lantern to pieces.
When inserting the lamp the shanks p¹, p" fixed to the oil-reservoir must be
introduced through the holes q, q, after which the whole lamp is turned from the
right to the left. The shank p¹ thereby forces aside the spring r which will prevent
the lamp from falling out.
A lateral movement of the upper part is prevented by the two guides n, n which
embrace the bars l, and are fastened to the ring a, while a vertical motion is
prevented by the hoop m, when not turned down.
For cleaning the lantern one need only to change the hoop m from the vertical
to a horizontal position, whereby the whole upper part can be easily taken out.
What I claim as new, and desire to secure by Letters Patent, is:
1. The arrangement of the hoop m and accessories for holding the upper part of
the lantern in place and allowing it to be lifted out of the lower part, when
required, substantially as described and illustrated.
2. The special shape of the double grooved bars e, e for holding the glass-panes
substantially as described and illustrated.
In witness whereof I the said Herbert John Haddan have hereunto set my
hand and seal this 18th day of July A.D. 1883.
