IMPROVEMENTS IN APPARATUS OR APPLIANCES FOR SECURING RUDDERS TO THE STERNS OF BOATS, LAUNCHES AND OTHER VESSELS
Year: 1884

page_text: I WILLIAM ABBOTT of Richmond in the County of Surrey, Professor of Music
do hereby declare the nature of said invention for "IMPROVEMENTS IN APPARATUS
OR APPLIANCES FOR SECURING RUDDERS TO THE STERNS OF BOATS, LAUNCHES
AND OTHER VESSELS" to be as follows:-
-
The object of my invention is to afford a ready and efficient means for securing
rudders to boats, launches and other vessels whereby the same can be shipped and
unshipped with facility while at the same time the rudder is securely held in
position and although the invention is applicable for use as applied to launches
however they may be propelled whether by steam, electricity or otherwise, still the
invention is more particularly applicable to rowing or sailing boats.
According to my invention I apply to the stern or stern post a long spindle or
pintle extending from the lower end of the stern or stern post up to or near to the
top thereof; to the rudder a tube of a length corresponding with the length of
the pintle is connected or the tube need not necessarily be the whole length of the
pintle; with however a long pintle and a long tube the latter is easily slipped over
the former. There is a hinged catch on the stern or stern post which when the
rudder is slipped on comes down over the spindle and tube and into a slot in the
stern post; if desired for greater security a pin or other suitable fastening is
provided for securing the parts in position so that the tube cannot be removed from
its spindle until the pin or fastening is removed.
By the arrangement before described there is no trouble as heretofore to find the
pintle which when the boat is afloat is generally under water and when the rudder
is slipped on and secured as aforesaid it is almost impossible for the same to come
off as is often now the case accidentally. The steering power of the rudder too is
more effective, and its strength is increased because of the long bearing surface
afforded by the long spindle and tube.

do hereby declare the nature of my said invention for "IMPROVEMENTS IN
APPARATUS OR APPLIANCES FOR SECURING RUDDERS TO THE STERNS OF BOATS
LAUNCHES AND OTHER VESSELS," and in what manner the same is to be per-
formed, to be particularly described and ascertained in and by the following
statement:—
The object of my invention is to afford a ready and efficient means for securing
rudders to boats launches and other vessels, so that they can be shipped and
unshipped with facility. Although my invention is applicable to all kinds of
boats or vessels, still it is more particularly adapted to small rowing or sailing
boats.
My invention consists in applying to the stern post of a boat or its equivalent, a
long pin or pintle, extending from the keel band to the top of the stern post. This
pin or pintle may be either part of the keel band or it may be fixed to it; the top
of the pintle may be either secured to the stern post by a hing, or permanent, catch
or clip.
On to the rudder is fixed a tube of an internal diameter to fit the pintle on the
boat and of a length preferably less than the length of the pintle so that the rudder
may rise and fall when it comes into contact with any obstruction.
When I use a hing clip to support the top of the pintle I prefer to make the tube
on the rudder solid-drawn, but as this necessitates releasing the hing catch each
time the rudder is shipped or unshipped I provide a pin passing through both the
clip or catch and the pintle to lock them together, for greater security; but when
I use a permanent clip for the pintle I cut a slot down the tube throughout its
entire length to allow the tube to pass the pintle clip, so that the rudder may be
shipped or unshipped without releasing or unfastening anything.
By the use of the arrangement as herein before described, there is no trouble in
finding the pintle to ship the rudder, as the top of it is above the water when the
boat is afloat, which is not the case with the arrangements at present in use. Owing
to the long bearing afforded by the long pintle and tube the stability of the rudder
is greatly increased.
In the accompanying drawings on which similar parts are marked with like
letters of reference
Fig 1 shows a side view of my arrangement. A designates the stern post of the
boat. B the rudder. C the pintle connected to the keel band c. D the tube fixed
to the rudder. E the clip or catch hinged to the stern post of the boat A. and e. the
pin locking the catch E. to the pintle C. Fig 2 is a plan, partly in section, showing
the hing clip E. and Figs. 3 and 4 are an end elevation and a plan respectively
showing the pintle C. forming part of the keel band c. Figs. 5 and 6 are a side
view and a plan respectively showing my arrangement with the permanent clip E.
and the slotted tube D. the slot being designated by d.

page_text: I do not bind myself to the particular form of clip or catch described and shown
neither do I claim broadly the use of the slotted tube as I am aware that these
features of my invention are not new or novel but 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
The attachment of rudders to the sterns of small boats arranged and operating as
and for the purpose hereinbefore described and shown.
