Improvements in the Fittings of Rudders of Boats and
Small Vessels.
I, CHRISTOPHER NUGENT NIXON, of 57, Chancery Lane, in the county of
Middlesex, Gentleman, 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 said Invention relates to improvements in the fittings for securing rudders
to boats and small vessels. The said fittings are of such a nature that the rudder
can be readily shipped and unshipped, when desired, and it will be free to rise on
coming in contact with the ground or other object without becoming detached, and
will resume its proper position, when free from such obstacle.
Two guide bars are fixed, by means of straps, in a parallel position, to the stern
of the boat, in such a manner that a pintle may be passed between the same and
the stern, the strap securing the lower end of the said pintle to the rudder passing
through a space left between the two guide bars to a point below the lower ends
of the latter, whilst the pintle is arrested and retained in such a position that the
strap connecting the upper end thereof to the rudder remains above the tops of
the guide bars so that the rudder will be free to turn as desired. The pintle, and
with it the rudder, is arrested in the desired position by the lower end of the
pintle coming against a recessed projection or step, on which it rests and turns, the
said projection being secured to the stern of the boat by straps. In some cases,
instead of the said recessed projection or step, I arrange a hinged or moveable eye
or socket in the stern of the boat above the guide bars in such a manner that it
will fold back or move in suitable slots out of the way of the rudder when the
same is being shipped or unshipped, a pin projecting from the rudder gearing into
the said eye or socket, or, in some cases, I employ both the recessed projection or
step and the moveable eye or socket. When applying the fittings to boats having
curved sterns, instead of fixing one pintle to the rudder, as herein before described,
I hinge to the rudder, at suitable distances from each other, two or more buttons
or small pintles which are passed between the guide bars and the stern of
the boat, as herein before described. The necks of the hinges are made smaller
than the buttons or pintles to allow of their passing into the space between the
guide bars

page_text: Although I have in this specification described the guide bars as being secured to
the stern of the boat and the pintle to the rudder, it will be readily understood
that the positions of the various parts may be reversed, for instance, the guide rods
may be attached to the rudder and the pintle to the boat.
I will now proceed to refer to the accompanying drawings from which the
nature of my said Invention will be more clearly understood. The same letters of
reference indicate like parts in all the Figures. Figure 1. is an end elevation of a
boat with a flat stern, the moveable eye or socket b., above the guide bars a. a., is
shown arranged to slide up a slot in the plate b¹ before folding back, Figure 2. is
a side elevation of the stern of a boat and rudder, in which the recessed projection
or step c. is shown fixed below the guide bars a. a., d. is the pin attached to the
rudder for gearing into the moveable eye or socket b., e. is the pintle, and e¹ ell
the straps securing the same to the rudder, the strap e" is pressed together between
the pintle and the rudder in order that it may pass between the rods a. a.
Figure 3. is a side elevation of the stern of a boat and rudder in which the
pintle e. and projecting pin d. are shown attached to the stern, and the guide
bars a. a. and moveable eye or socket b. are connected to the rudder, Figure 4. is
an end elevation of a boat with a curved stern, and Figure 5. is a side elevation of
the stern of a similar boat and the rudder therefor, the necks of the hinges securing
the buttons e. to the rudder are made of smaller size than the buttons in order that
they may pass within the slot between the bars a. a., the rudder is arrested in
position by the lowest button coming into contact with the strap a. Figure 6. is
a view showing a rudder shipped, and Figure 7. is a side elevation of a stern of a
boat and rudder in which the moveable socket is dispensed with.
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 fittings for securing rudders to boats and other small vessels having
flat sterns or projecting stern posts, consisting of the combination and arrangement
of the guide bars a. a. and the pintle e. in conjunction with suitable means, such as
the recessed projection or step c., and the moveable eye or socket b. and the pin d.,
for arresting the rudder on reaching its proper position, substantially as, and for the
purposes, liereinbefore described and set forth.
And secondly. The fittings for securing the rudders to boats and other small
vessels having curved stern posts, consisting of the combination and arrangement
of the guide bars a. a. and the hinged buttons or small pintles e. e. e., substantially
as, and for the purposes, herein before described.
