Improvements in Buoy Lights.
I, WALTER JOHN MURPHY, of 39, Courtfield Gardens, Earl's Court, London,
Cable Engineer and Electrician, do hereby declare the nature of this invention
to be as follows:-
This invention relates to buoy lights and has for its object to improve the buoy
lights at present in use in which acetylene gas is employed as the illuminant by
constructing the same in a manner to allow of the charge of carbide from which
the gas is generated being more easily and readily transferred to the generating
chamber from a boat, and also to provide an improved means for securing a mast
or support, for the light, in position upon the buoy so that it may be readily
unshipped when required, and finally to construct the dome or case containing
the carbide and other parts in such a manner that it may be easily attached to any
suitable form of buoy, whether originally intended for lighting or not.
In carrying the invention into effect I construct a circular ring which forms a foun-
dation for a circular plate the plate forming the base of a dome containing the gas
generator which may be of any well known form at present in use for this purpose.
Upon the walls of the inner chamber I form a downwardly extending flange, the
flange inclining outwards from the walls, and which is designed to facilitate the
distribution of the water upon the carbide irrespective of the angle of the buoy
due to the swell of the waves. Upon one side of the inner chamber I form au
opening which may be sealed by any suitable form of water-tight door, but which
preferably consists of a plate of larger dimensions than the opening so as to allow
of a piece of rubber or the like being inserted between the face of the plate at its
edges and the side of the chamber, the plate being held against it by means of a
dog, the ends of which take into suitable eyes secured upon the outside of the
inner chamber, the dog being provided with a central stud or screw bearing
against the plate. A similar device is provided upon the dome but the plate in
this instance is hinged at one side and clamped at its edges by suitable clamping
devices. At the upper end of the dome I form a suitable socket, and upon the
end of the mast, which is of the usual form employed for such buoys, I form
a bayonet joint so that the same may be readily unshipped when so desired, but
at the same time renders the said joint gas tight.

page_text: 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:
This invention relates to buoy lights and has for its object to improve the buoy
lights at present in use in which acetylene gas is employed as the illuminant by
constructing the same in a manner to allow of the charge of carbide from which
the gas is generated being more easily and readily transferred to the generating
chamber from a boat, and also to provide an improved means for securing a mast
or support for the light in position upon the buoy so that it may be readily
unshipped when required and finally to construct the dome or case containing
the carbide and other parts in such a manner that it may be easily attached to any
suitable form of buoy, whether originally intended for lighting or not.
In carrying the invention into effect I construct a circular ring of metal which
forms a foundation for a circular plate which is dished in the centre, the plane
portion and the walls thereof respectively forming a means for the attachment
thereto of an outer dome shaped cylindrical chamber and an inner or generating
chamber in which the carbide container (which may be of any known form
suitable for this purpose) is placed.
Upon the walls of the inner chamber I form a flange, the flange inclining out-
wards from the walls so as to facilitate the distribution of the water upon the
carbide irrespective of the angle of the buoy due to the swell of the waves. Upon
the inner chamber I form an opening of such dimensions as to readily allow of
the introduction therein of the carbide container. This opening is hermetically
closed by means of a suitable door or cover which may be of any convenient and
suitable form, a like device being provided to seal the opening formed in the outer
shell or chamber aforesaid.
In order that the invention may be the better understood drawings are
appended:
Fig. 1 being an external elevational view of part of a buoy to which the inven-
tion has been applied.
Fig. 2 is a vertical section thereof to an enlarged scale and
Fig. 3 is a transverse section showing the position of the two openings and the
inner and outer shells or chambers. is the buoy to which is secured in any
suitable manner the foundation in the present case a circular ring of metal
although the form of such foundation would of necessity be varied to suit the
contour of the surface of the buoy to which the invention was to be applied.
Bolted or otherwise attached to the ring is a circular plate e dished as shown
at d and provided with an upwardly extending concentrically disposed flange e to
which is secured the dome shaped outer chamber f. Concentrically disposed with
regard to the outer chamber f is an inner cylindrical chamber g of smaller dimen-
sions and having placed within it the carbide container . Running round the
inside of the chamberg and at a somewhat higher level than the top of the con-
tainer is an inclined ledge i the purpose of which is to distribute the water irre-
spective of the inclination of the buoy caused by the swell of the waves. Water
is admitted to the inner chamber through the tube j the quantity being regulated
by the plug to which access is obtained by means of the cap or cover upon the
outer chamber f by which cap water is also introduced into the water reservoir
formed at the upper end of the chamber f by the horizontal partition m.
n indi-
cates an opening formed in the wall of the inner chamber of such dimensions
as to allow of the ready introduction therein of the carbide container h. The
opening is closed by means of the curved plate o under the edges of which is
inserted a rubber packing ring the plate being pressed against same by means
of the screw q passing through the dog the ends of which take into the eyes ss
secured upon the outside of the chamber g. t is an opening formed in the outer
chamber of corresponding dimensions to that in the inner chamber and closed by
a door or cover u preferably hinged upon one side and secured at the edges by

page_text: clamps or the like a rubber washer being inserted beneath the edges of the
said door. At the upper end of the dome shaped outer chamber is secured a
socket A having formed in it recesses with which engage projections B upon the
lower end of the mast C the whole forming a baynot joint with a rubber or other
washer D to prevent the escape of gas which passes up the tube E to the lamp at
the top of the mast. It will be obvious from the foregoing that the insertion or
removal of the carbide container may be easily and readily effected and the mast
may be readily unshipped when required.
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. In a buoy light of the kind herein described the construction and arrange-
ment of the same whereby the removal or introduction of the carbide container
may be easily and readily accomplished from a boat, substantially as herein
described and illustrated in the appended drawings.
2. In a buoy light the provision of a simple means whereby the unshipping of
the mast may be easily accomplished substantially as herein described and illus.
trated by the appended drawings.
3. The improvements in buoy lights substantially as herein described and
illustrated by the appended drawings.
