An Improved Plug for Boats.
Year: 1899

page_text: I, ALFRED ERNEST WARDER, Engineer, of Clevehurst, West Cowes, Isle of
Wight, do hereby declare the nature of this invention to be as follows:-
-
This invention relates to an improved plug for use in connection with small
boats which are usually provided with holes for cleaning and draining purposes,
and the object is to provide a plug suitable for this purpose which can be easily
fitted in place or withdrawn and which will at the same time effectually plug
the holes.
The plug consists of a small screwed pin having a head which is preferably
formed with a small annular recess or channel the head being screwed upon the
head of the pin or formed in one with it. This pin passes through a tube or
thimble which is stepped or formed with a double flange at one end, the other
end fitting into the channel of the head.
Between the inner flange of the tube and the head of the pin a thick rubber
ring is fitted and on drawing the head and flange together, the rubber ring is
compressed lengthwise causing it to bulge out at the sides. For this purpose a
small nut is provided screwed upon the end of the pin and provided with finger
pieces by which it can be turned.
The nut bears on top of the flanged tube or ring so that on screwing it down
the rubber ring is caused to expand transversely. The plug is placed in the
hole, the flange preventing it passing through and the rubber ring is then
expanded so that the plug binds tightly in the hole.
To remove the plug all that is required is to give a slight turn to the nut.

An Improved Plug for Boats.
I. ALFRED ERNEST WARDER, Engineer, of Clevehurst, West Cowes, Isle of
Wight, 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:.

page_text: The plug consists of a small screwed pin having a head which is preferably
formed with a small annular recess or channel the head being screwed upon the
bead of the pin or formed in one with it. This pin passes through a tube or
thimble which is stepped or formed with a double flange at one end, the other
end fitting into the channel of the head.
Between the inner flange of the tube and the head of the pin a thick rubber
ring is fitted and on drawing the head and flange together, the rubber ring is
compressed lengthwise causing it to bulge out at the sides. For this purpose a
small nut is provided screwed upon the end of the pin and provided with finger
pieces by which it can be turned.
The nut bears on top of the flanged tube or ring so that on screwing it down
the rubber ring is caused to expand transversely. The plug is placed in the
hole, the flange preventing it passing through and the rubber ring is then
expanded so that the plug binds tightly in the hole.
To remove the plug all that is required is to give a slight turn to the nut.
In order that this invention may be more clearly described reference is had
to the accompanying sheet of illustrative drawings on which
Fig. 1 is a vertical section of a boat plug constructed according to this inven-
tion and
Fig. 2 is a plan of the same.
The screwed pin A is provided with a head A' in which is formed an annular
recess or channel a. The head A may be either formed in one with the pin A or
attached thereto by screwing or otherwise as is most convenient.
The tube or
thimble B is formed with a stepped or double flange B¹ at one end while at the
<ther end it is adapted to fit in the channel or groove a of the head A' when the
iwo parts are put together. The pin A is adapted to pass through the centre of
the tube or thimble B which is perforated for the purpose.
A thick ring C of rubber is fitted between the head A¹ and the flange B₁ as
shown. A butterfly or other suitable nut is fitted upon the screw end of the pin A
and as will be readily seen serves for drawing the parts together. The rubber
ing C is thus compressed lengthwise and therefore is caused to bulge out at
the sides.
When the cleaning of the boat or other portion has been completed the plug
is placed in the hole and on tightening the nut the rubber expands so as to hold
the plug securely in the hole. The stepped flange D¹ prevents the plug from
passing entirely through the hole. To remove the plug all that is required is
to release the nut sufficiently to reduce the binding action of the rubber ring.
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) An improved plug for boats consisting of a screw pin having a head
portion, a tube or thimble having a flange and through which the screw pin
passes a rubber ring fitting between the head of the screw pin and the flange
of the tube or thimble and a nut whereby the parts can be tightened up to
cause the rubber ring to expand transversely so as to bind in the hole, sub-
stantially as described.
(2) An improved plug for boats comprising the pin A having a head A' and
an annular groove a, a tube or thimble B having a stepped flange B', a rubber
ring C, and a nut D, substantially as described, with reference to the drawings
and for the purposes specified.
