do hereby declare the nature of my said invention for AN IMPROVED ARRANGE-
MENT FOR ATTACHING RUDDERS TO SMALL BOATS to be as follows:-

The object of my invention is to mount the rudder of small boats, whether
rowing or sculling boats, sailing boats, torpedo boats, or steam launches, so that it
may be shipped or unshipped with the utmost facility and so that it will be free
to rise without becoming unshipped if it should come into contact with anything
that would tend to lift it.
My arrangement is an improvement on those described and shown by Patent
No 9445-1884 and the application for a patent No 15,588-1884 of which I am
the sole proprietor.
My arrangement consists in fixing to the stern post of the boat near the top of
it a long split socket, and near the bottom of it an eye of the usual description.
On to the rudder is fixed a long pin, which is connected to it either directly or
indirectly by two straps or their equivalent; one of these straps is near the top of.
the rudder and the other in close proximity to the bottom eye which is placed
a sufficient distance from the keel of the boat so that if the rudder should rise
through coming in contact with anything, the pin will not be lifted out of the
bottom eye. The bottom strap is attached to the pin by a thin web, so that it may
be dropped into position by passing through the slot in the split socket at the top
of the stern post.
As the stern post of many of the lighter boats are raked I prefer to set the
straps which connect the pin to the rudder so that they will lie parallel with the
keel of the boat although the pin is at an angle therewith. As it is an expensive
operation to make the pin in one piece with the straps I prefer to make them in
separate pieces and pin them together afterwards during which operation they may
be set at any angle.

An Improved Arrangement for Attaching Rudders to Small
Boats.
I ALBERT TOM FRAMPTON of East Molesey in the County of Surrey Gentleman,
do hereby declare the nature of my said invention for "AN IMPROVED ARRANGE-
MENT FOR ATTACHING RUDDERS TO SMALL BOATS," and in what manner the
same is to be performed, to be particularly described and ascertained in and by
the following statement :-
The object of my invention is to mount the rudder of small boats, whether
rowing or sculling boats, sailing boats, torpedo boats, or steam launches, so that it
may be shipped or unshipped with the utmost facility & so that it will be free to
rise, without becoming unshipped if it should come into contact with anything that
would tend to lift it.
My arrangement is an improvement on those described and shown by Patent
No 9445-1884 and the application for a Patent No 15588-1884 of which I am
the sole proprietor.
My arrangement consists in fixing to the stern post of the boat near the top of
it a long split socket, and near the bottom of it an eye of the usual description.
On to the rudder is fixed a long pin or pintle which is connected to it either
directly or indirectly by two straps or their equivalents; one of these straps is near
the top of the rudder and the other in close proximity to the bottom eye which is
placed a sufficient distance from the keel of the boat so that if the rudder should
rise through coming in contact with anything the pin will not be lifted out of the
bottom eye. The bottom strap is attached to the pin by a thin web, so that it may
be dropped into position by passing through the slot in the split socket at the top
of the stern post.
As the stern post of many of the lighter boats are raked I prefer to set the
straps which connect the pin to the rudder so that they will lie parallel with the
keel of the boat although the pin is at an angle therwith. As it is an expensive
operation to make the pin in one piece with the straps I prefer to make them in
separate pieces and pin them together afterwards, during which operation they
may be set at any angle.
In order that my invention may be fully understood I will more particularly
describe it making reference to the accompanying drawings on which similar parts
are marked with like letters of reference.
In the accompanying drawings Fig. 1 is a view showing my arrangement the
rudder being set at right angles to the boat. Fig. 2 is an end elevation and Fig. 3
a side elevation of a boat showing the fittings. Fig. 4 is a side elevation of the
rudder showing the long pintle. Fig. 5 is an elevation and Fig. 6 a plan, on an
enlarged scale of the split socket. Fig. 7 is a section of the pintle just above the
bottom strap, and Fig. 8 is a view showing the arrangement as applied to boats
with raking sterns.
Referring to these figures A designates the split socket fixed to the stern of the
boat X. B designates the eye to receive the lower end of the pintle. This eye is

page_text: preferably made in one piece with the keel band and is shown thus in the drawings,
though I do not bind myself to this particular method of construction. On to the
rudder Y is fixed by two strap cand c¹ the pintle C. The bottom strap c³ is
connected to the pintle by a narrow web c² which when the rudder is being shipped
or unshipped passes through the slot a in the socket A. When the rudder is
shipped this web lies in the space between the socket A and the eye B and the
rudder is therefore free to turn in either direction, or to rise and fall at any angle.
In boats with raked sterns I prefer to construct the pintle and the strap in
separate pieces and pin or otherwise fix them together afterwards to suit the
particular angle of any boat, as shown by Fig. 8.
It will be seen that mounting rudders according to my invention as hereinbefore
set forth, they may be shipped or unshipped with the greatest facility and they are
free to rise and fall within certain limits without becoming unshipped. To ship
the rudder it is only necessary to slide the lower end of the pintle into the top of
the slotted socket until the web on the lower strap has entered the slot, and then
let it drop, when it will at one seat itself.
I am aware that split sockets have been used before in combination with
continuous pintles, but they have been faulty in design and costly to manufacture
and have therefore never been brought into practical use. I therefore do not
broadly claim the use of them, 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
First. The arrangement for attaching and mounting rudders substantially as
hereinbefore described and shown.
Secondly. The combination of the split socket A, the eye B, and the pintle C, all
constructed, arranged and operating as and for the purpose hereinbefore described.
