AN IMPROVED METHOD OF ATTACHING BOATS RUDDERS
Year: 1884

page_text: I, HENRY EMANUEL Croft Lodge, Surbiton, Surrey Gentleman do hereby
declare the nature of my invention for AN IMPROVED METHOD OF ATTACHING
BOATS RUDDERS, to be as follows:-
A metal tube or suitably constructed hollow cylinder of requisite dimensions
having a slot running its whole length at a right angle to its ends, is recessed &
screwed, or otherwise centrally & vertically fixed into the transom of the boat,
from the top of the transom to within a few inches of the bottom of the stern
post. This slot lies centrally outwards. The tube takes the place of the ordinary
gudgeons or eyes. To & between the rudder straps in lieu of pintles or hooks &
at the points on the straps where the pintles ordinarily hang I fix a metal rod or
spindle, whose diameter is slightly less than the inside of the slotted tube, in which
it can therefore work freely. The straps are distant from each other an inch or so
more than the length of the tube the spindle between the straps is therefore longer
than the tube; so that when the spindle is in the tube the lower joint or web
piece connecting the spindle end to the lower strap is below & clear of the tube,
& the spindle & rudder can work right or left. I secure the top of the spindle to
the top rudder strap by a horizontal flat piece of metal into which at a suitable
distance from the shoulder of the strap I tap, or braze, or solder, or rivet, or
otherwise fasten the head of the spindle; the part carrying the spindle has a
circumference greater than the spindle, so that when the spindle is in a working
position, this collar, or projecting edge, forms a cap or bearing, & axis, over the
head of the tube, allowing the spindle to partly revolve without falling through
the tube.
Conversely to the plan described above, the spindle may be fixed to the transom
& the tube to the rudder.
An auxiliary rudder & spindle may be shipped either by a single central tube as
above described, or may slide down into two or more tubes or channels fitted in
the sides of the main rudder. In an auxiliary rudder, as its spindle or core would
not (partly) revolve in its tube, the shape or design of the spindle or core may be
other than circular.

page_text: I HENRY EMANUEL of. Croft Lodge Surbiton Surrey Gentleman do hereby
declare the nature of my invention for "AN IMPROVED METHOD OF ATTACHING
BOATS' RUDDERS " and in what manner the same is to be performed to be
particularly described and ascertained in and by the following statement :-
A metal tube having a slot running nearly its whole length is laid on or recessed
and screwed or otherwise centrally and vertically fixed to the transon of the boat.
Near the lower end of the tube the slot is enlarged to accommodate the lower
strap on the rudder.
To the rudder where the pintles ordinarily hang I fix by means of the straps a
metal rod or spindle of a size to enter within the slotted tube.
The top rudder straps are formed with a horizontal piece into which I tap or
otherwise fasten the head of the spindle. The part carrying the spindle has a
circumference greater than the spindle so that when the spindle is in working
position this collar takes a bearing on the head of the tube. I secure the lower
straps to the spindle by a short piece or feather brazed or otherwise fixed into a
slot near the lower end of the spindle.
To prevent the rudder rising when. not required to do so I supply a radial arm
with a projection which when the arm is vertical forms a butt or stop to the
spindle collar. To unship the rudder I throw this arm to right or left and the
spindle then can pass upwards.
:
The arrangement is reversible the tube may be fixed upon the rudder and the
spindle upon the transom of the boát.
In order that my said invention may be most fully understood and readily
carried into effect I will proceed to describe the drawings hereunto annexed.
Figures 1, 2, 3 and 3* are respectively a side view a front elevation and transverse
sections of the tube to be fixed to the transom of the boat. a is the slot therein
and a¹ the enlargement or widening of this slot at its lower end.
A plain drawn tube suitably slotted as shown may be employed.
Figure 4 is a side elevation of the spindle with the straps by which it is secured
to the rudder. Figure 5 is a plan of the upper strap and Figure 6 is a plan of the
lower strap. Figure 7 is a.section of the spindle which may however be solid."
Figure 8 is a front elevation and Figure 9 is a side elevation of the turn button to
prevent the rudder rising.
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) My improved method of attaching boats rudders consisting in the employ-
ment of a tube slotted as described and fixed to the transom of the boat and a
continuous spindle secured by straps to the rudder as herein specified.
.

page_text: (2) The modification of the said method which consists in fixing the tube to the
rudder and the spindle to the transom of the boat as herein specified.
(3) The combined apparatus consisting of the solid drawn and slotted tube and
the spindle entering the tube and provided with straps for its attachment as herein
specified.
