We GEORGE LUDWIG SCHULTZ and DANIEL CAMPBELL Merchants both of
90 Cannon Street in the City of London do hereby declare the nature of this
invention to be as follows:-
-
Our invention relates to the construction of the shells of buoys, and also the
shells or cases of submarine mines or torpedoes, the object being to produce them
of greater strength so as to resist concussion and pressure of all kinds better, yet
with a lesser thickness of metal than heretofore.
Spherical shaped submarine mines or torpedoes have heretofore been produced
from two hollow hemispheres of metal stamped or formed in any suitable way and
rivetted to an inner Tee ring. By our invention it is proposed to stamp or press
each of such hemispheres with an outer flange at their peripheries, the two flanges
being rivetted, bolted, or otherwise secured together. This method of fastening
dispensing with the inner Tee ring, and allowing when the flanges are simply
bolted together of the easier examination of the interior or for greater security one
flange may be lapped over the other and the two bolted together. Such openings
as are required it is proposed to form with an internally or externally projecting
flange or ring to give them greater strength. The walls of the hemispheres may
also have longitudinal or lateral corrugations stamped or otherwise formed in them,
such corrugations giving greater strength to the shell, and allowing of the employ-
ment of a thinner metal than heretofore, beside giving an increased surface thus
producing a shell of considerably greater buoyancy than heretofore.
It is evident that the corrugations and the flanging described may be applied to
shells spherical cylindrical conoidal or of other shapes, a good form consisting of
two half shells slightly curved to a radius between that of a perfect sphere and the
straight line of a cone. Each half of the conical shaped buoys instead of being
stamped may be formed from a sheet of metal bent into shape, the two edges being
turned inward and folded or lapped over each other, forming a longitudinal joint
to complete which the shell may if desired be revolved in spelter or sealed in any
other suitable way.

page_text: Improvements in Buoys and Shells for Submarine Mines and
Torpedoes.
We, GEORGE LUDWIG SCHULTZ and DANIEL CAMPBELL, Merchants both of
90 Cannon Street in the City of London 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:-
Our invention relates to construction of the shells of buoys, and also the shells
or cases of submarine mines or torpedoes, the object being to produce them of
greater strength, so as to resist concussion and pressure of all kinds better, yet
with a lesser thickness of metal than heretofore.
Spherical shaped submarine mines or torpedoes have heretofore been produced
from two hollow hemispheres of metal stamped or formed in any suitable way and
riveted to an inner Tee ring. By our invention it is proposed to stamp or press
each of such hemispheres with an outer flange at their peripheries, the two flanges
being rivetted, bolted, or otherwise secured together. This method of fastening
dispensing with the inner Tee ring, and allowing when the flanges are simply
bolted together, of the easier examination of the interior, or for greater security
one flange may be lapped over the other and the two bolted together. Such
openings as are required it is proposed to form with an internally or externally
projecting flange or ring to give them greater strength. The shells may also have
longitudinal or lateral corrugations stamped or otherwise formed in them, such
corrugations giving greater strength to the shell, and allowing of the employment
of a thinner metal than usually employed, thus producing a shell of considerably
greater buoyancy than heretofore.
It is evident that the corrugations and the flanging described may be applied to
shells, spherical, cylindrical, conoidal or of other shapes, a good form consisting of
two half shells slightly curved to a radius between that of a perfect sphere and the
straight line of a cone. Each half of the conical shaped buoys instead of being
stamped may be formed from a sheet of metal bent into shape, the two edges being
turned inward and folded or lapped over each other, forming a longitudinal joint to
complete which the shell may if desired be revolved in spelter or sealed in any
other suitable way.
To clearly illustrate the construction of the buoys and shells reference is made
to the accompanying drawings in which-
Fig. 1 shows in section a spherical shell formed in two halves which are stamped
or pressed from a metal plate and secured together at the flanges by bolts a the
lower half of the shell having a circular opening 6, at the bottom, through which
when it is to be employed as a torpedo or mine it may be filled, the opening being
afterwards closed by a suitable cover secured thereto.
Fig. 2 shows a similar shell secured by rivets a at the flanges, the opening b at
the bottom however being formed with an external flange or ring o which serves to
stiffen it, and to which the closing cover may be readily attached.

page_text: Fig. 3 shows a shell the two halves of which are rivetted to the usual internal
Tee ring d, the lower half being provided with an internal stiffening flange or
ring c around the opening.
Fig. 4 shows a shell having corrugations or depressions f, and a projecting
opening in the lower shell closed by a suitable cover the two halves of the shell
being rivetted to the asual internal Tee ring.
Fig. 5 illustrates a similarly corrugated shell, having the external flanges and an
internal stiffening ring or flange c around the opening.
Figs. 6 and 7 show two methods of securing the halves together, to form perfect
joints, the first showing the flange on the upper half bent over the edge of the
lower, the two being rivetted together, and the second showing the lower flange
bent over and upon the upper, a rivet a securing the three thicknesses of plate
together while around the joint spelter may be run if desired.
Fig. 8 illustrates in section a shell formed with lateral corrugations, flanges and
an external stiffening ring around the opening, the two halves being formed by
stamping or bending a metal plate.
Fig. 9 shows one half of a double cone shaped shell, more particularly adapted
for buoys, formed from a plate of metal which is bent around with a cone, the two
edges being folded over into a longitudinal seam g. The flanges of two of these
cones are rivetted or bolted together and if desired the flange may be revolved in
spelter to ensure a tight joint. The cone is shown as having an opening at
the top.
Fig. 10, is a section of same on the line A, B.
Fig. 11, is a similarly shaped buoy stamped and bent from a metal plate and has
corrugations as described for the spherical shells. It is shown with an upper and
lower opening which are closed in any suitable way.
Fig. 12 shows a buoy or mine formed of the two flanged half shells which are
curved to a radius between that of the sphere and the straight line of the cone,
it being shown as having an internal stiffening ring c around the upper and an
external ring around the lower opening.
Fig. 13 shows a portion of a similar shell, the corrugations however being
omitted and the lower flange being lapped over the upper as shown in Fig. 7.
These buoys and mines may be provided with rings or handles has shown, at
suitable points, which serve either for attaching, mooring, or anchoring ropes or
chains to, or for handling or other purposes, and will also carry any of the other
attachments which are employed with metal shells or buoys of this class.
As already stated we are aware that it is not new to form buoys or mines of
spherical shape of stamped metal bolted to an inner Tee ring and provided with
rings or other means for attachment to mooring ropes or chains and we do not
claim such construction as part of our invention 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 and in shells for submarine mines and torpedoes
substantially as described and as illustrated in the accompanying drawings.
