WILLIAM PELHAM BULLIVANT of 72 Mark Lane in the City of London Wire
Rope Manufacturer do hereby declare the nature of this Invention to be as
follows:-
My Invention has for its object to provide a moro effective and convenient means
of connection of, torpedo net booms to the sides of ships or other places to which
they are to be attached.
According to my Invention I provide in the boss projecting from the vessels side
(or the like) or froin a plate attached thereto an orifice in a direction at right angles
to the vessels side. The pin or eye bolt which is secured to the heel end of the boom
is passed into this orifice so that it projects at right angles to the ship's side. Or in
place of a pin bolt I may use a simple link to be passed into the orifice. By means
of a cotter pin or the like passed transversely through the boss and the eye bolt or
link the boom is secured in place, but any other suitable way of securing the eye bolt
or its equivalent in the orifice arranged as described may be used for instance in the
case of an eye bolt it may be screwed into the orifice in the boss. Owing to the
position of the parts the strains are much better distributed than hitherto.

Improvements in Attachments for Connecting Booms for Supporting
Torpedo Nets to the Sides of Vessels or the like.
I WILLIAM PELHAM BULLIVANT of 72 Mark Lane in the City of London Wire
Rope Manufacturer 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 :—
My Invention has for its object to provide a more effective and convenient means
of connection of torpedo net booms to the sides of ships or other places to which
they are to be attached.
According to my Invention I provide in the boss projecting from the vessels side
(or the like) or from a plate attached thereto an orifice in a direction at right angles
to the vessels side. The pin or eye bolt which is attached to the heel end of the boom
is passed into this orifice so that it projects at right angles to the ships side. Or in
place of a pin or eye bolt I may use a simple link to be passed into the orifice. By
means of a cotter pin or the like passed transversely through the boss and the
eye bolt or link the boom is secured in place but any other suitable way of securing
the eye bolt or its equivalent in the orifice arranged as described may be used for
instance in the case of an eye bolt it may be screwed into the orifice in the boss.
Owing to the position of the parts the strains are much better distributed than hitherto.
And in order that my Invention may be well understood I will describe with
reference to the accompanying Drawings manners in which the same may be carried
into practical effect.
Fig. 1 is a side view and Fig. 2 a section (on the line 1. 2. Figure 1) shewing one
modification according to my Invention. The part of the boom shewn is marked a
and the heel attachment secured therein is marked y. The heel attachment may be

page_text: either secured inside a metal (preferably steel or iron) tube constituting the boom or
the boom and heel attachment may be of the usual or any suitable kind and mode of
attachment to each other. To the eye of this heel attachment is attached the eye of
the pin or eye bolt z which is provided with a shoulder 22.
The stem portion of the said pin or bolt is passed into an orifice in the boss A
furnished with a plate a by which it is secured to the side of the vessel or other place
indicated at B so that the said pin or bolt projects at or about right angles to
the part B. A cotter C is passed transversely through holes in the boss A and
stem to secure the pin or bolt in place or instead of a cotter the stem
may be scrow threaded and screwed into a corresponding screw in the orifice in the
boss A as shewn in Figure 3.
Figures 4 and 5 are respectively a side view and front view of a boss A fitted or
shaped for the reception in its orifice of a link 23 instead of a bolt or pin as in
Figures 1, 2 & 3. This link is secured to the heel attachment y of the boom as
shewn in the plan Fig. 6 and when the link is passed into the orifice in the boss A
the cotter C is passed through the holes for it in the boss and throngh the link
as shewn clearly in the Drawings.
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 :-
For connecting torpedo net booms to the sides of vessels or to other places a
boss or projection attached to or formed on the side or place to which the boom is to
be connected the said boss having therein an orifice as shewn into which is
inserted a pin or eye bolt or a link connected to the heel attachment of the boom
and retained in position in the said orifice of the boss substantially as herein before
described and illustrated in the accompanying Drawings.
