Year: 1885

page_text: We DANIEL CAMPBELL and GEORGE LUDWIG SCHULTZ both of 90 Cannon Street
in the City of London, and SAMUEL JAMES FELLOws of Wolverhampton, Engineers,
do hereby declare the nature of this invention to be as follows:-
This invention relates to Buoys, more especially those of a small size, such
as are suitable for marking channels, for surveying purposes, cable laying or for
torpedoes.
The buoys are formed somewhat as described in a provisional specification filed
on the 29th day of September 1885 No 11,575, and are in two parts or halves with
flanged edges, which are either stamped from solid plates, or seamed up the side or
sides, the former way we consider however to be preferable. They may be either
plain or corrugated, and of egg shape or other suitable form. The halves are
secured together by bolting or rivetting the flanges to each other, or for additional
security, the flange of one half may be made of considerably greater, width than
the other, for the purpose of folding over it, after which the two (and any inter-
mediate diaphragm or plate) are bolted or rivetted together, and for further
security soldered if desired thus forming a strong and watertight joint.
In the centre of such a buoy we now propose to place a tube running throughout
its length (if it be of elliptical shape) and secured at both ends of the buoy, thus
adding greatly to its strength. The lower end of the tube is closed by a plug or
solid portion, and in it is inserted a swivel ring for anchoring and other purposes,
the upper end being left open for the insertion of a post, flág or signal staff, or the
lower swivel may be dispensed with, and a chain or rope passed through the tube,
and secured by a washer or collar in the end. If the buoy is required for mooring
purposes only, a flanged socket or plug is also inserted in the upper end of the
tube, and through both plugs and tube is passed a bolt, the entire length of the
buoy, in which case both ends may carry a swivel,

We DANIEL CAMPBELL and GEORGE LUDWIG SCHULTZ both of 90 Cannon Street
in the City of London, and SAMUEL JAMES FELLOWS of Wolverhampton, Engineers,
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:
This invention relates to buoys, more especially those of a small size, such as
are suitable for marking channels, for surveying purposes, cable laying or for
torpedoes.
The buoys are formed somewhat as described in a provisional specification filed
on the 29th day of September 1885 No 11,575, and are in two parts or halves with
flanged edges, which are either stamped from solid plates, or seamed up the side or
sides, the former way we consider however to be preferable. They may be either
plain or corrugated, and of egg shape or other suitable form. The halves are
secured together by bolting or rivetting the flanges to each other, or for additional
security, the flange of one half may be made of considerably greater width than
the other, for the purpose of folding over it, after which the two (and any inter-
mediate diaphragm or plate) may be bolted or rivetted together, and for further
security soldered if desired thus forming a strong and watertight joint.
In the centre of such a buoy we now propose to place when desired a tube running
in part or throughout its length (if it be of elliptical shape) and secured at both
ends of the buoy, thus adding greatly to its strength. When the tube runs
throughout the length the lower end of the tube is closed by a plug or solid
portion, and in it is inserted a swivel ring for anchoring and other purposes, the
upper end being left open for the insertion of a post, flag or signal staff, or the
lower swivel may be dispensed with, and a chain or rope passed through the tube,
and secured by a washer or collar in the end.
To clearly explain the nature of our invention reference is made to the accom-
panying drawings, the figures of which show different modifications of the
invention.
Fig. 1 represents an egg shaped buoy formed in two halves, the upper having
corrugations stamped or otherwise formed in it and carrying a short tube or socket b
for the reception of a flag or signal staff and a ring c which may be used for
mooring or other purposes. The lower portion (which may also be corrugated)
carries a swivel ring d to which the anchoring or detaining chain is attached. The
two halves are secured together by the flanges which are left after the portions
have been stamped or otherwise formed, and which are turned and pressed over the
thickened or ring edge of a diaphragm A as shown at i the lower flange lapping
over the upper or vice versa, solder being. run around it to finish the joint if
desired. The lower half may be perforated as shown if desired, for the purpose of
allowing the water to enter and keep the buoy upright when used for signalling it 4
being prevented from sinking by the diaphragm which leaves a buoyant air
chamber above..
Fig. 2 shows a somewhat similar buoy the corrugations however being omitted,
a concavo-convex diaphragm being employed for the purpose of giving greater
buoyancy when the lower part is filled with water, and the ring c being arranged
to swivel. The method of securing the two halves together at i is more clearly
shown and will be described with reference to Fig. 9.

page_text: Fig. 3 shows a buoy having a slightly concavo-convex diaphragm, the flanges
being turned over the ring edge thereof the diaphragm supporting a short tube b
for the reception of a flag or signal staff which tube is closed by a cover e when
not in use as shown.
+
Fig. 4 is a similar buoy having a flat diaphragm and lower perforations.
Figs. 5 and 6 represent buoys having a tube running throughout their length, a
plug (to which is secured a swivel d) closing the lower opening of the former,
while the latter bas a plug at each end through both of which are passed a rod g
which strengthens the buoy and also serves as a means of attachment for the upper
and lower swivels. Both of said buoys are shown with a central diaphragm which
is secured around the tube by a ring h, its periphery being further held by the
lapped and bolted flanges at i as more clearly shown by the enlarged view thereof
represented by Fig. 7.
Fig. 6 shows the lower portion of a buoy having a chain passed into the tube
and secured by a washer or collar in the end.
Fig. shows the same joint applied to a buoy in which tube b is omitted and the
top plate lapped over the lower.
Fig. 9 is an enlarged view of the joint for the buoys illustrated in Figs. 2 and 10
(which latter represents an otherwise plain buoy with top swivel) the joint being
made by turning the periphery of the diaphragm A partly over a solid ring j, the
flange of the lower half of the buoy being bent underneath to meet it, while the
whole is secured together by the larger flange of the upper portion which is bent
around and pressed upon them from beneath, solder being run round the joint if
desired.
Fig. 11 represents a corrugated buoy the bolt g of which running through the
centre strengthens it, and also secures the upper flagstaff socket and lower swivel
upon the body of the buoy, the lapped or folded joint and centre diaphragm being
also employed.
Figs. 12 and 13 show the short sockets or tubes in section, the former having
the ring c for mooring purposes while the latter is plain. Both are rivetted
through the metal of the buoy to strengthening plates k beneath.
Fig. 14 shows a plain buoy having the lapped joint with a tube b running part
way through its length and resting upon the diaphragm A.
Figs. 15 and 16 show methods of forming the joint where no diaphragm is
employed, a strip of bulb iron j being bent and welded into a ring, the flanges of
the upper and lower halves being bent around it. In Fig. 16 the bulb iron has a
collar formed thereon."
At all points where the heavier metal parts such as the swivels and sockets are
to be rivetted to the lighter metal of the buoy it is desirable that the strengthening
plates k should be employed, while around the flagstaff tubes where they rest upon
the diaphragms, rings of angle iron may be placed and all of such buoys may be
perforated if desired.
We do not confine ourselves to the exact arrangement of parts shown in each
figure, as the same may be reversed, varied or altered as desired but―
Having now particularly described and ascertained the nature of our said
invention, and in what manner the same is to be performed we declare that what
we claim is
The Improvements in Buoys substantially as hereinbefore described and as
illustrated in the accompanying drawings.
