and Working of Torpedo Net Defences.
I, WILLIAM PELHAM BULLIVANT, of 72, Mark Lane, in the City of London, Wire
Rope Maker, do hereby declare the nature of this invention to be as follows:-
Hitherto it has been usual in connection with the attachment and working of
torpedo net defences to fit the end of the torpedo net boom with a band provided
with lugs for the attachment of shackles for fastening the jack stay to which
releasing hooks are sometimes attached. According to my invention I make the
lugs themselves also act as releasing hooks by making the lugs in the form of
hooks hinged at one end to the boom fitting and retained at the other end by a
pin or screw passed through the said fitting so as to support the end of the combined
hook and lug when it is required to hold the jack stay or rope the said pin or screw
being withdrawn when the jack stay or rope is to be released.

An Improved Device for Use in connection with the Attachment
and Working of Torpedo Net Defences.
I, WILLIAM PELHAM BULLIVANT, of 72, Mark Lane, in the City of London, Wire
Rope Maker, 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:-
.
Hitherto it has been usual in connection with the attachment and working of
torpedo net defences to fit the end of the torpedo net boom with a band provided
with lugs for the attachment of shackles for fastening the jack-stay to which releasing
hooks are sometimes attached. According to my invention I make the lugs themselves
also act as releasing hooks by making the lugs each in the form of a hook which, at
one end, is hinged to the boom fitting and, at the other end, is connected to the
said fitting in such a manner that it may be readily separated therefrom when the
jack-stay or rope is to be released.
I will describe my invention by reference to the accompanying drawings in
which:-
Figure 1 is a plan shewing on respectively opposite sides of the central line xx
two slightly different forms of the device constructed according to my invention..

page_text: Figure 2 is a view shewing at the left hand side an end elevation of the
corresponding part of Figure 1 and, at the right hand side, a section on the line 2-2
of Figure 1 and
Figure 3 is a side elevation of the device shewn at the left hand side of Figures 1
and 2.
Like letters of reference indicate like parts throughout the different figures of the
drawings..
In carrying my invention into practice I form the boom fitting A preferably as a
casting and connect thereto one end of each of the combined hooks and lugs B by
means of a pivot or hinge pin C so that the said combined hook and lug may be
swung outwards from the fitting A in the manner shewn in dotted lines in Figure 1.
The end 6 of the combined hook and lug B may be detachably connected to the
boom-fitting A either by a removeable pin or screw D passing through it and the
fitting A as shewn at the right hand side of Figure or by a ring D¹ pivotted to
the fitting A and passing over the end b as shewn at the left hand side of Figure 1,
this ring D¹ if desired, being secured against accidental displacement during its
engagement with the combined hook and lug B, and during the retention of the
jack-stay or rope, by a pin or equivalent inserted in a hole in the end 6; or the
ends of the combined hooks and lugs B may be detachably connected to
the boom-fitting A in any other convenient manner.
When it is desired to release the jack-stay or rope connected with an arrangement
such as that shewn at the right hand side of Figure 1 all that is necessary is to
remove the pin or screw D and turn the combined hook and lug B outwards as
shewn in dotted lines, and when it is desired to effect a similar release in connection
with the device shewn at the left hand side of Figure, it is necessary to first
remove the before mentioned pin or equivalent from the hole b₁ (when such pin is
provided) and then turn the ring D¹ off the end b and afterwards swing the combined
hook and lug B outwards from the fitting A.
Although I have shewn the fitting A as a device adapted for attachment to a
torpedo net boom, which is the arrangement I prefer, I may form it as an integral
part of the said boom.
Having now particularly described and ascertained the nature of my inven-
tion and in what manner the same is to be performed, I declare that what I
claim is
1. In a device for use in connection with the attachment and working of torpedo
net defences the combination with a torpedo-net boom of a combined hook and lug
such as B hinged on or to the said boom, substantially as hereinbefore described
with reference to the accompanying drawings.
2. The combination with a torpedo net boom having a combined hook and lug
such as B hinged at one end on or to the said boom, of an adjustable fastening
device for detachably connecting the other end of the combined hook and lug to
the boom substantially as herein before described with reference to the accompanying
drawings.
3. The combination and arrangement of parts constituting either of the two
devices for use in connection with the attachment and working of torpedo net
of the
defences substantially as herein before described and illustrated in Figure
accompanying drawings.
