Improvements in-or connected with Rudder Fittings.
•
I, CHRISTOPHER NUGENT NIXON, of 43, St. Luke's Road, Clapham, in the
County of London, Gentleman, do hereby declare the nature of this invention
to be as follows:
-
This invention relates to improvements in or connected with rudder fittings and
has for its object to construct the fittings in such manner that the rudder may
rise in its bearings without becoming accidentally unshipped, whilst, at the same
time, it may be readily shipped and unshipped when required.
In carrying the invention into effect, a tube is formed with a flat back and a
longitudinal slit or slot in the front and extending the entire length thereof, and
this flat backed tube which constitutes a long gudgeon for the pintle of the rudder
is fixed to the stern post of the vessel by means of straps, the upper ones of which
are formed with open sided eyes or clips of a similar section to that of the tube and
the lower one of which is formed with a socket to receive the end of the tube.
In connection with this long gudgeon, a long pintle is employed which at its
upper end is fixed by brazing or otherwise in a socket or fitting carried by a strap
at the upper part of the rudder and at the lower end the long pintle is socketed to
fix upon a stud or it may be fixed within a socket carried by a strap fixed with the
rudder at the lower part thereof and this strap is formed with a narrow neck to
pass down the slit of the long gudgeon.
The lower strap carries a short pintle which is received into a socket bearing
carried by the lower strap of the rudder post, whilst, in order to prevent the acci-
dental lifting and possible unshipping of the rudder, a suitable stop is employed,
as is well understood.
It will be obvious that the parts may, if desired, be reversed, that is to say, the
long tubular gudgeon may be carried by the rudder and the pintle may be carried
by the stern post of the vessel, but, in this case, the long gudgeon would be formed
at the upper part with a bearing to hang on to the upper end of the pintle.
If desired, the long tubular gudgeon may be cut away at intervals or made in
sections to facilitate manufacture and to prevent the same becoming choked in use.
By the means herein before described, rudder fittings are much strengthened,
the steadiness of the rudder is improved, the general strength of the fittings is
superior to those of the ordinary character, whilst, at the same time, they are much
less expensive to produce.

I, CHRISTOPHER NUGENT NIXON, of No. 43, St. Luke's Road, Clapham, in the
County of London, 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 or connected with rudder fittings,
and has for its object to construct the fittings, so that they may be more easily and
cheaply manufactured in parts and so that one size may be adaptable to different
depths of stern. The fittings are applied in such manner that the rudder may rise
in its bearings without becoming accidentally unshipped, whilst, at the same time,
it may be readily shipped and unshipped, when required.
In carrying the invention into effect, a tube is formed with a flat back and a
longitudinal slit or slot in the front and extending the entire length thereof but
curved off at the lower end so as to facilitate the unshipping of the rudder and this
flat backed tube which constitutes a long gudgeon for the pintle of the rudder is
fixed to the stern post of the boat or vessel by means of straps, the upper ones of
which are formed with open sided eyes or clips of a similar section to that of the
tube, and the lower one of which is formed with a socket to receive the end of the
tube or in lieu of this it might simply abut on the lower strap gudgeon attached
to the stern post.
In connection with this long gudgeon, a long pintle is employed which at its
upper end is fixed by brazing or otherwise in a socket or fitting carried by a strap
at the upper part of the rudder and at the lower end of the long pintle is socketed
to fix upon a stud or it may be fixed within a socket carried by a strap fixed with
the rudder at the lower part thereof and this strap is formed with a narrow neck to
pass down the slit of the long gudgeon.
The lower strap carries a short pintle which is received into a socket bearing
carried by the lower strap of the rudder post, whilst in order to prevent the acci-
dental lifting and possible unshipping of the rudder a suitable stop is employed,
as is well understood.
It will be obvious that the parts may, if desired, be reversed, that is to say, the
long tubular gudgeon may be carried by the rudder and the pintle may be carried
by the stern post of the vessel but in this case the long gudgeon would be formed
at the upper part with a bearing to hang on to and pivot on the upper end of the
pintle.
The long tubular gudgeon may be cut away at intervals or made in sections to
facilitate manufacture and to prevent the same becoming choked in use and this
latter method is preferable in most cases.
And, in order that the said invention may be more clearly understood, and readily
carried into effect, I will proceed, aided by the accompanying drawings, more fully
to describe the same.

rudder.
Figure 15. is a horizontal section taken on the line 2-2 of Figure 14. and
Figure 16, is a horizontal section taken on the line 3-3 of Figure 14.
In the several figures like parts are indicated by similar letters of reference.
Referring to Figures 1 to 8., a represents the boat or vessel, b represents the
gudgeon, c represents the pintle, and represents the rudder.
According to the present invention the gudgeon b is formed of a tube provided
with a flat back and a longitudinal slit or slot b¹ in the front extending the entire
length thereof, but a curve b² is formed at the lower part of the tube in order to
facilitate the unshipping of the rudder at the times desired.
This flat backed tube 6 which constitutes a long gudgeon for the pintle c of the
rudder is fixed to the stern post of the vessel a by means of a strap 63 at the upper
part which is formed integral with the tubular gudgeon as represented at Figures
1. to 8., or, it might be formed separate therefrom, and with eyes or clips of a similar
section to the tubular gudgeon 6 adapted to embrace the tube as represented at
Figure 9. and which clips would be slotted to correspond with the slit 61 of the
gudgeon b.
The lower strap 64 is formed separate from the tubular gudgeon b, and is pro-
vided with a socket or recess 65 adapted to receive a projection or tenon 66 formed
upon the lower end of the flat back of the tubular gudgeon b.
Or, the projection 66 and recess 65 might be dispensed with and the lower end of
the flat back of the tubular gudgeon b might simply rest or abut upon the strap 64
at the point 65, as will be readily understood.
The strap balso carries a step 68 for the pintle c of the rudder and an eye b
in continuation of the tubular gudgeon 6 and through which the lower end of the
pintle passes.
In connection with the long tubular gudgeon 6 is employed a long solid pintle c
which at its upper end is received into a socketed or recessed fitting c² carried
by a strap cl which is fixed with the upper part of the rudder d by means of screws,
rivets, or otherwise, whilst the lower end of the long solid pintle e is socketed or
recessed to fit upon a stud c5 fixed with a fitting carried by a strap adapted to
be fixed with the rudder d at the lower part thereof and the fitting also carries a
downwardly extending short pintle c* shaped in continuation of the long pintle c.
In lieu of the long pintle c being socketed to fit upon the stud c³ a socket may
be formed in the fitting to receive the lower end of the long pintle c in a similar
manner to that adopted with respect to the upper end thereof.
The straps care respectively connected with their fittings c² 4 by narrow
necks 2 c which are of such dimensions as to allow the one c* to pass down
the slot or slit 6 of the long tubular gudgeon b and thus permit the long solid
pintle c to be introduced into the gudgeon 6 until the short pintle c* is received
into the step or bearing 68 herein before referred to.
In order to prevent the accidental lifting and possible unshipping of the rudder d
when the device is applied to steam launches, or large boats or barges, where it is
not required to frequently ship and unship the rudder as in small boats, a stop or

page_text: "lock" is employed which might consist of a strap e embracing the rudder head, d¹
and hinged on one side at e¹ and on the other side forked to embrace a hasp or
fitting e, a pin being provided to lock those parts together and this device would
prevent the rudder rising unless or until it is turned upon its hinge e¹ and moved
out of the way.
In the example given at Figures 10 to 12., the long gudgeon b is cut away at
intervals so as to leave openings 6* in order to facilitate manufacture and prevent
the device becoming choked when in use, or the device might be made in sections
transversely divided with a similar object but the arrangement represented at
Figures 10. and 11. is the preferred one.
In connection with this sectional or skeleton gudgeon is employed a long tubular
pintle c somewhat similar in construction to the solid pintles hereinbefore described
except that the upper part c** of the pintle c is formed solid and fixed with the
fitting of the upper strap c¹ and the lower part c* thereof is similarly formed
and fixed with the fitting c of the lower strap whilst the intermediate part
is formed tubular, and its upper part fits into a socket c**I formed in the part c**,
and at its lower end fits upon a stud carried by the fitting c* in a similar manner
to that described with respect to the previous figures.
By this construction, the manufacture of the device is facilitated whilst the solid
parts
** and c* of the pintle form the wearing surfaces, and thus the device obtains
the requisite strength.
In the example given at Figure 13., the parts are assumed to be substantially
the same as those represented at Figures 10. to 12. but in this case they are reversed,
that is to say, the long tubular or sectional gudgeon 6 is carried by the rudder d
and the tubular pintle c is carried by the stern post of the boat or vessel but in this
case the long gudgeon is formed at its upper part with a socket 68 to hang and
pivot upon the upper end of the pintle c which projects above its upper strap for
that purpose.
In the example given at Figures 14. to 16., which represents the application of
the invention to a counter stern vessel, the long tubular gudgeon b is dispensed
with and the straps 63 64 are placed close together whilst they are provided with
eyes or fittings 63* 64* through which the pintle c passes and the upper one of
these fittings 63* is formed with a slot or opening 61 therein and the pintle c is
formed with a corresponding flat or reduced part e adapted to pass through the
slot b¹ and thus release the rudder at the times desired.
In this example, in order to prevent the rudder becoming accidentally unshipped,
a lock e is employed consisting of a fitting e' in which a cap e horizontally slides
so that it may be moved out of the way to allow the rudder d to rise sufficiently
to pass through the slot b¹ of the strap fitting 63* whilst in order to fix the parts in
position against accidental movement a pin is employed which passes through
corresponding eyes formed in the cap e and fitting e¹.
By the means hereinbefore described, the manufacture of rudder fittings of this
class is facilitated whilst at the same time they are much less expensive to produce
than similar contrivances heretofore adopted.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what I
claim is:
1. In rudder fittings, the combination of a long gudgeon consisting of a slotted
tube or sectional tube, a co-acting long pintle and a step for the pintle separate from
the gudgeon but forming a rest or abutment therefor, substantially as herein shown
and described.
2. In rudder fittings, the combination of a long flat backed gudgeon formed of a
slotted tube or sectional tube and a co-acting long pintle and a step for the pintle
separate from the gudgeon, substantially as herein shown and described.
3. In rudder fittings, the combination of a long gudgeon consisting of a long
slotted tube or the like, suitable fillings, a long pintle formed separate from the

page_text: fittings, and connected therewith by socket joints or the like, a short pintle carried
by the lower fitting and a co-acting step, substantially as herein shown and
described.
4. In rudder fittings, of the character herein before shown and described, a
removeable lock or stop located above water for preventing the accidental unshipp-
ing of the rudder, substantially as herein shown and described.
