AN IMPROVEMENT IN FLOATING LIGHTS
Year: 1882

page_text: LETTERS PATENT to John Imray, of No. 28, Southampton Buildings, in the
County of Middlesex, for an Invention of "AN IMPROVEMENT IN FLOATING
LIGHTS." A communication from abroad by Julius Pintsch, of Berlin, in the
German Empire.
PROVISIONAL SPECIFICATION left by the said John Imray at the Office
of the Commissioners of Patents on the 6th March 1882..
JOHN IMRAY of No. 28 Southampton Buildings in the County of Middlesex.
"AN IMPROVEMENT IN FLOATING LIGHTS." [A communication from abroad by
Julius Pintsch, of Berlin, in the German Empire.]
In the Specification to Abel's Patent dated 21st Nov. 1876 No. 4515 are
described arrangements for maintaining gas lights. on buoys and other floating
vessels, the gas being compressed into a reservoir on board the floating vessel, and
passed to the burner or burners through a regulator whereby its pressure is reduced
and governed. It is found that when buoys or floating vessels thus lighted are
subjected to severe concussions such as may result from impact of wreckage or from
shocks of waves, the gas burning at the low pressure to which it is reduced by the
regulator is apt to be extinguished. This Invention relates to means of rekindling
the light when such extinction occurs. For this purpose, close beside the burner
or group of burners which is supplied with the low pressure gas and which con-
stitutes the main light, there is placed a small jet supplied with gas directly from
the reservoir of compressed gas without passing through the regulator. The shocks
which may extinguish the low pressure lights do not extinguish this bigh pressure
jet which remains burning and rekindles the main lights. A convenient arrange-
ment of combined burner for the purpose stated is to branch the low pressure jets
from a box supplied by a pipe from the regulator, and through the centre of this
box to carry up a pipe which is supplied from the reservoir of compressed gas and
terminates in a small jet that burns in the midst of the low pressure burners so
that it at once rekindles them after their extinction. The tubular stem of the
high pressure jet is preferably made to screw into a box or cavity below and to
present a closed coned end immediately over the supply aperture of the cavity
so that according as the stem is screwed more or less down its coned end acts
as a valve governing the admission of high pressure gas to the cavity. From
the cavity the gas finds its way into the tubular stem and supplies the high
pressure jet.

AN IMPROVEMENT IN FLOATING LIGHTS." A communication from abroad by
Julius Pintsch of Berlin in the German Empire.
In the Specification to Abel's Patent dated 21st November 1876 No. 4515 are
described arrangements for maintaing gas lights on buoys and other floating
vessels, the gas being compressed into a reservoir on board the floating vessel, and
passed to the burner or burners through a regulator whereby its pressure is reduced
and governed. It is found that when buoys or floating vessels thus lighted are
subjected to severe concussions such as may result from impact of wreckage or from
shocks of waves, the gas burning at the low pressure to which it is reduced by the
regulator is apt to be extinguished. This Invention relates to means of rekindling
the light when such extinction occurs. For this purpose, close beside the burners
or group of burners which is supplied with the low pressure gas and which con-
stitutes the main light, there is placed a small jet supplied with gas directly from
the reservoir of compressed gas without passing through the regulator. The shocks
which may extinguish the low pressure lights do not extinguish this high pressure
jet which remains burning and rekindles the main lights. A convenient arrange-,
ment of combined burner for the purpose stated is to branch the low pressure jets
from a box supplied by a pipe from the regulator, and through the centre of this
box to carry up a pipe which is supplied from the reservoir of compressed gas and
terminates in a small jet that burns in the midst of the low pressure burners so
that it at once rekindles them after their extinction. The tubular stem of the
high pressure jet is preferably made to screw into a box or cavity below and
to present a closed coned end immediately over the supply aperture, of the cavity
so that according as the stem is screwed more or less down its coned end acts
as a valve governing the admission of high pressure gas to the cavity. From
the cavity the gas finds its way into the tubular stem and supplies the high
pressure jet.
Fig 1 of the accompanying Drawings is a vertical section and Fig 2 a sectional
plan of a burner according to this Invention. A block a having at its base a
fange b by which it is screwed to the lantern is centrally bored and has a lateral
communication c with the pipe B by which compressed gas is supplied direct from
the reservoir. At its upper part the block a expands into a cavity e which is
supplied by a lateral communication d from the pipe A, with low pressure gas
which has passed through the regulator. From the cavity e are supplied the low
pressure burners m which are screwed into the cover f of the cavity e. In the
midst of these burners is serewed the burner i of the kindling jet. The stem
terminates at its lower end in a cone h with small lateral passages into the central
bore k. The cone h being immediately above a narrow passage g from the central
bore of a, the supply of gas to the burner i can be varied by screwing the burner
inwards or outwards. n is a sloping shield forming the bottom of the lantern, with
perforations near its outer edge for admitting air.

Having thus described the nature of this Invention and in what manner the
same is to be performed as communicated to me by my foreign correspondent,
I claim
For floating lights which are supplied with gas compressed into a reservoir and

page_text: passed through a regulator to the burners, the combination of a central adjustable
high pressure gas jet with the low pressure burners, substantially as and for the
purpose herein set forth.
In witness whereof I the said John Imray have bereunto set my hand and
seal this First day of August in the year of our Lord One thousand eight
hundred and eighty-two.
