trouble inconvenience loss of time and heavy expenses incurred by shipping and
unshipping vessels' rudders with long heads which go to the top of poop or

quadrant or tiller keyed on the top in the usual way
Second in a ship with a closed poop the quadrant or tiller will be fixed above
the poop and a boss with flange fixed and keyed on the ordinary rudder head
(instead of being fixed on top of quadrant or tiller as in the arrangement previously
described) and the two flanges fastened with bolts and nuts.

MATTHEW HORSLEY of Hartlepool in the County of Durham "IMPROVEMENTS
IN MOUNTING SO AS TO FACILITATE THE SHIPPING AND UNSHIPPING THE RUDDERS
OF SHIPS AND OTHER VESSELS PARTLY APPLICABLE TO OTHER LIKE PURPOSES
:
This Invention relates to an improved method or means for shipping and
unshipping vessels rudders with long heads as hereafter described and is intended
to prevent the great trouble, inconvenience, loss of time and heavy expenses
incurred by shipping and unshipping vessels rudders with long heads which go
to the top of poop or "Liverpool house" aft where the steering wheel and gear
are fixed.
The present system of shipping and unshipping rudders with long heads is known
both by ship builders and ship owners to be most inconvenient whether done in
dry-dock on slipways or afloat but more especially so in foreign ports where there
are little or no facilities for doing such work and is therefore objectionable.
Owing to the frequent casualties which happen by ships rudders being damaged
or broken at sea and those on board baving no means of unshipping the broken one
and shipping another one instead the lives of all on board and also the vessels and
cargoes are thereby put in imminent danger and risk of both valuable lives and
property being lost. This risk is incurred for want of some suitable means whereby
the above circumstances may be partially relieved if not entirely avoided.
Under the present system large vessels in general have to be afloat to ship and
unship their rudders.
By my improved system of having the rudders made in two or more parts as
hereafter described the shipping and unshipping of rudders with long heads (or
ordinary rudders having tiller and quadrant fixed which cannot be removed without
great delay, inconvenience and expense) can be accomplished by uncoupling the
upper part of the rudder from the lower part and rising the upper part the length
of the rudder pintles the lower part can be unshipped and re-shipped either afloat
on slipway or in dry dock without removing the tiller and quadrant or steering
gear attached thereto.
Besides if vessels propelled by steam have to take a spare propeller on board so
all vessels trading on long voyages should take a spare upper part of rudder on
board for the safety of life and property especially so, as it is very seldom that a
rudder is damaged or broken under water but generally at the upper part which is
out of water and consequently more exposed to be damaged or broken by sea in a
storm.

page_text: The new improved system which I employ for this purpose is very simple but at
the same time complete and effectual as illustrated by figures 1, 2 and 3.
And in order that my invention may be clearly understood I will now describe
the same more fully, reference being made to the drawings hereto annexed.
First In a ship having a "Liverpool house"-with-after steering gear fixed-on
the-top-and-the-quadrant or tiller for bridge gear fixed-below just above the main
deek-as-represented in Figure 1 of the drawing the rudder is made according to
my improvements in two parts a and b the lower part-b-being the same as an
ordinary rudder with quadrant-or-tiller c-fixed on the top.--This quadrant-or-tiller-c
has a boss-c¹-made-rather-thicker-than-usual and the upper-part of rudder-a-with-a
flange-a¹-at-lower-end-which-is-fastened-to-the-boss-of-quadrant or tiller c-with bolts
and nuts as shown; or in a similar way to the mainshaft couplings in a sorew
steamer and the quadrant or tiller c is keyed on the top in the usual way as
shown.
;
Second. In-a-ship with a closed poop the quadrant or tiller-c-will be fixed-upon
the-poop as shown in figure 2, and a boss with flange fixed and keyed on the
ordinary rudder head-(instead of being fixed on-top-of quadrant-or tiller-as-in-the
arrangements previously--described) and the two flanges fastened with bolts and
nuts. In this ease the ordinary rudder trunk can be used with a small slide (or
other)-door-d-(or more-than-one slide or other-doors if found-necessary) or by an
angle-iron-forming-a-flange-at-each-side and a plate-aeross the back-fastened-with
bolts and nuts, or by a plate (or plates)-fastened with top bolts on the back (or
other-parts)-of-the-rudder-trunk-above-main-deek so-as-to-get-at-the-serew-nuts in
the coupling e-when the rudder--has-to-be--unshipped--in--accordance with my
improvements. The doors can be made of plate glass and fitted and fastened
outside rudder trunk (similar to windows-in-ships sterns or side lights) so as the
couplings-can-be-seen-at-any-time.
If any damage-should occur-to-steering-gear wheel or upper part of rudder at
sea so as to necessitate the removing and replacing of the same it can be done
without the least risk as the couplings and all connected therewith-are-between
deeks.
Third First. In this arrangement the couplings e are outside the stern below
the rudder trunk as shown in figure 31, the lower flange is upon the head of the
rudder b just above the frame and the upper flange upon the lower end of the upper
part a of rudder head both flanges are forged as parts of the rudder head to which
they belong and fastened together with bolts and nuts and keyed through between
the centres of the flanges.
Fourth Second.-In this arrangement represented by figure 4 2 the couplings e
are the same as those just before described the only difference being in the shape.
of the stern post, the one by having a bend the other by a recess, corresponding
parts being marked with similar letters of reference.
Fifth Third. In this arrangement the couplings e as represented in Figure 5 3
are upon the upper part of the rudder and the flanges form part of the frame and
are fastened together with bolts and nuts and keyed longitudinally between the
flanges, (the ends of the flanges next the stern post can be used as stops for the
rudder if approved.)
This-coupling-ean-be-made-to-suit any ship or vessel whether large-or-small-new
or old-as-the original rudder can be made-to-suit, and the stern post-and rudder
trunk would do without any alteration. It would also-prevent the trouble-and
inconvenience of removing the quadrant or tiller which ean-seldom (if ever)-be
refastened-as-securely-as-it-was-at-first-fastened.
These couplings can be made to suit any ship or vessel whether new or old as the
original rudder (of old ships) can be made or altered to suit and the stern post
and rudder trunk would do without any alteration and all the sections as described.
above in Figures 1, 2 and 3 and represented by the drawings when the rudder has
to be shipped or unshipped will save the heavy expenses, trouble and inconvenience

in figures 31, 42, and 5 3, it cannot be repaired in a storm as, the whole of the

This Invention relates to an improved method or means for shipping and
unshipping vessels rudders with long heads and is intended to prevent the great
trouble, inconvenience, loss of time and heavy expenses incurred by shipping and
unshipping vessels rudders with long heads which go to the top of poop or

both by ship builders and ship owners to be most inconvenient whether donei
dry-dock on slipways or afloat but more especially so in foreign ports where there
are little or no facilities for doing such work and is therefore objectionable.
.
Owing to the frequent casualties which happen by ships rudders being damaged
or broken at sea and those on board having no means of unshipping the broken one
and shipping another one instead the lives of all on board and also the vessels and

Under the present system large vessels in general have to be afloat to ship and
unship their rudders.
By my improved system of having the rudders made in two or more parts the
shipping and unshipping of rudders with long heads (or ordinary rudders having
tiller and quadrant fixed which cannot be removed without great delay, incon-
venience and expense) can be accomplished by uncoupling the upper part of the
rudder from the lower part and rising the upper part the length of the rudder
pintles the lower part can be unshipped and re-shipped either afloat on slipway or

Besides if vessels propelled by steam have to take a spare propellor on board so
all vessels trading on long voyages should take a spare upper part of rudder on
board for the safety of life and property especially so, as it is very seldom that a
rudder is damaged or broken under water but generally at the upper part which is
out of water and consequently more exposed to be damaged or broken by sea in a
storm.
The new, improved system which I employ for this purpose is very simple but at
the same time complete and effectual,
And in order that my invention may be clearly understood. I will now describe
the same more fully, reference being made to the drawings hereto annexed.
First. In a ship having a "Liverpool house" with after steering gear fixed on
the top and the quadrant or tiller for bridge gear fixed below just above the main
deck as represented in Figure 1 of the drawing the rudder is made according to my
improvements in two parts a and b the lower part 6 being the same as an ordinary
rudder with quadrant or tiller c'fixed on the top. This quadrant or tiller c has a
boss c¹ made rather thicker than usual and the upper part of rudder a with a
flange a¹ at lower end which is fastened to the boss of quadrant or, tiller c with
bolts and nuts as shown, or in a similar way to the mainshaft couplings in a screw
steamer and the quadrant or tiller c is keyed on the top in the usual way as
shown.
Second. In a ship with a closed poop the quadrant or tiller c will be fixed upon
the poop as shown in figure 2, and a boss with flange fixed and keyed on the
ordinary rudder head (instead of being fixed on top of quadrant or tiller as in the
arrangements previously described) and the two flanges fastened with bolts and
nuts. In this case the ordinary rudder trunk can be used with a small slide (or
other) door d (or more than one slide or other doors if found necessary) or by an
angle iron forming a flange at each side and a plate across the back fastened with
bolts and nuts, or by a plate (or plates) fastened with top bolts on the back (or
other parts) of the rudder trunk above main deck so as to get at the screw nuts in
the coupling e when the rudder has to be unshipped in accordance with my
improvements. The doors can be made of plate glass and fitted and fastened
outside rudder trunk (similar to windows in ships sterns or side lights) so as the
couplings can be seen at any time.
If any damage should occur to steering gear wheel or upper part of rudder at sea
so as to necessitate the removing and replacing of the same it can be done
without the least risk as the couplings and all connected therewith are between
decks.

page_text: Third. In this arrangement the couplings e are outside the stern below the rudder
trunk as shown in figure 3, the lower flange is upon the head of the rudder b just
above the frame and the upper flange upon the lower end of the upper part a of
rudder head both flanges are forged as parts of the rudder head to which they
belong and fastened together with bolts and nuts and keyed through between the
centres of the flanges.
Fourth. In this arrangement represented by figure 4 the couplings e are the same
as those just before described the only difference being in the shape of the stern
post, the one by a bend the other by a recess, corresponding parts being marked with
similar letters of reference.
Fifth. In this arrangement the couplings e as represented in Figure 5 are upon
the upper part of the rudder and the flanges form part of the frame and are fastened
together with bolts and nuts and keyed longitudinally between the flanges, (the
ends of the flanges next the stern post can be used as stops for the rudder if
approved.)
This coupling can be made to suit any ship or vessel whether large or small new
or old as the original rudder can be made to suit, and the stern post and rudder
trunk would do without any alteration. It would also prevent the trouble and
inconvenience of removing the quadrant or tiller which can seldom (if ever) be
refastened as securely as it was at first fastened.
If any damage should occur to the upper part of rudder at sea (as represented in
figures 3, 4 and 5, it cannot be repaired in a storm as the whole of the couplings
are outside ships stern between the counter and the load water line, but it can be
done when the storm ceases and the sea smooth or by getting the vessels into the
nearest bay, roadstead or harbour under such circumstances there would be no need
