I, JOHN DAMPIER HICKMAN, of Portsmouth Road, Thames Dition, in the County of
Surrey, Cycle Manufacturer and Engineer, do hereby declare the nature of this invention
to be as follows:-
:-
My invention relates to an improved construction of attachments for hanging
rudders of boats, and small craft generally, to their respective stern posts; and has
more particular reference to means by which large rudders can be shipped or
unshipped, without risking the fall of both man and rudder overboard.
My invention is applicable to any of the well known detachable rudder-attachments,
and I will describe it in connection with an attachment consisting of a tee bar, to
which the rudder is hinged, in combination with a groove fixed to the stern post, and
into, and with, which groove, the said tee bar is adapted to, respectively, enter and
engage, for the purpose of shipping the rudder; although I wish it to be distinctly
understood that my invention is applicable to any modification of the tee bar and
groove attachment.
It has hitherto been the practice to make the groove continuous, so that the foot of
the fee bar entered at the top thereof. With small rudders no great inconvenience
has been caused by this necessity, but with a heavy rudder and a rough sea, the case
has been different. The man has been obliged to lift the rudder into a vertical
position, and consequently expose himself to the imminent risk of being overbalanced
and pitched overboard.
To obviate this risk of accident, and to facilitate the shipping of the rudder under
any circumstances; I cut away the front flanges of the groove from about the water
line to the top; and to the top of the groove or to an equivalent part of the stern post,
I hinge a short length of groove, which is, consequently, adapted to either lie upon
the top of the stern post, or to stand upon the groove which is fixed upon the stern post.
The outer extremities of the flanges of the said short length of groove are,
preferably, cut away.
To ship the rudder; the nose of the tee bar, preferably rounded off, is laid into the
trough of the short piece of groove and pushed forward to engage in said groove.

page_text: The rudder is then swung up upon the above mentioned hinge into a vertical position,
and dropping down the opened groove on the stern post and engages in the lower
part thereof.
Suitable stops are provided at either end of the attachment.

I, JOHN DAMPIER HICKMAN, of Portsmouth Road, Thames Ditton, in the County of
Surrey, Cycle Manufacturer and Engineer, 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 invention relates to an improved construction of attachments for hanging
rudders of boats, and small craft generally, 10 their respective stern-posts; and has
more particular reference to means by which large rudders can be shipped or
unshipped, without risking the fail of both man and rudder overboard.
My invention is applicable to any of the well-known detachable rudder-attachments;
and will describe it in connection with an attachment, consisting of a tee bar, to
which the rudder is hinged, in combination with a groove fixed to the stern-post, and
into, and with, which groove, the said tee bar is adapted to, respectively, enter and
engage, for the purpose of shipping the rudder; although I wish it to be distinctly
understood that my invention is applicable to any modification of the tec-bar and
groove attachment.
It has hitherto been the practice to make the groove continuous, so that the foot of
the ice-bar entered at the top thereof. With small rudders no great inconvenience
has been caused by this necessity, but with a heavy rudder and a rough sea, the case
has been different. The man has been obliged to lift the rudder into a vertical position,
and has consequently exposed himself to the imminent risk of being overbalanced and
pitched overboard.
To obviate this risk of accident, and io facilitate the shipping of the rudder under
any circumstances. I cut away the front flanges of the groove from about the water
line to the top; and to the top of the groove, or to an equivalent part of the stern-post,
I hinge a short length of groove, which is consequently adapted to either lie upon the
top of the stern-post, or to stand upon the groove which is fixed upon the stern post.

page_text: The outer extremities of the flanges of the said short length of groove are, preferably,
cut away
To ship the rudder, the nose of the tee-bar, preferably rounded off, is laid into the
trough of the short piece of groove, and pushed forward to engage in said groove.
The rudder is then swung up upon the above mentioned hinge into a vertical position,
and dropping down the opened groove on the stern post, engages in the lower part
thereof.
Suitable stops are provided at either end of the attachment.
In order that my invention, and the means by which the same may be carried into
practical effect, may be thoroughly understood, I will proceed now to describe the
same in detail, referring in so doing to the accompanying drawings which are to be
taken as part of this specification and read therewith, and which illustrate the applica-
tion of my invention to a rudder attachment as described in the specification of my
Letters Patent, No. 6870, 5th June, 1885.
Fig. 1 is a side elevation of a boat-stern and rudder to which my invention has been
applied. The full lines shew the rudder shipped, and the dotted lines shew it in
process of being shipped or unshipped.
Fig. 2 is a perspective view illustrating the relative positions of the parts when the
act of unshipping the rudder is on the point of completion.
Fig. 3 is a front elevation of the groove on the stern-post.
A is the rudder furnished with a metal T-bar, a, which is jointed to the rudder
according to any convenient method.
B is the metal groove of a suitable section to receive the said T-bar. This groove
stops short of the top of the stern-post to make room for the pivotted rudder-
guide, C.
I wish it to be distinctly understood that the application of my invention is not
confined to rudders fitted with a tee-bar and groove attachment as the same is
illustrated in the drawings and described in my former specification above referred to,
but is applicable to any rudder-attachment consisting of a bar and groove adapted to
engage the one with the other, or to be disengaged at will.
A plate, b, is, preferably, fixed over the top angle of the stern-post for the purpose
of protecting it from wear and tear.
The front flanges, , of the groove are cut away from about the water-line
upwards.
C is the rudder-guide. It consists of a short piece of metal groove of the same
section as the groove, B. This is pivotally connected in any suitable way to the top
of the stern-post, D, in such a way that when it swings down upon the top of the said
groove, 13, it shall be continuous therewith, as illustrated in Figs. 1 and 3.
The back of the said short piece, C, is continued upwards, forming an extension, c.
A rudder fitted with an attachment constructed according to my invention is shipped
in the following manner.
The rudder-guide is turned back upon the top of the stern-post, where it will be in
a horizontal position as indicated by the dotted lines in Fig. 1. The rudder is then
held in a corresponding position, and the bottom end or nose of the T-bar, a, is laid
upon the extension, c, of the guide, and the rudder pushed forward until the T-bar
engages in the guide, C.
The head of the rudder is then raised, the T-bar pushed farther through the guide,
the latter being at the same time swung outwards, until the T-bar bears against the
part, 6, of the groove opened up by the removal of parts of the groove-flanges, bl.
The rudder is then allowed to drop, the only steadying required being a push outwards
against the T-bar which latter will engage in the lower part of the groove as it slides
downwards, and the rudder will be safely and properly shipped.
Any suitable stop is provided at either end of the attachment.
The process of unshipping the rudder is the exact reverse of the one described
above.
The drawings and foregoing description do not exhaust all the methods in which
my invention can he applied, inasmuch as the relative positions of the groove, B, and

page_text: T-bar, a, may be reversed, the groove being then hinged to the rudder, A, and having
its front flanges continuous. The T-bar, according to this modification, would be
fixed to the stern-post, with part of its flanges cut away. The rudder-guide also would
consist of a piece of T-bar.
Although the above described drawings illustrate my invention as applied to a
straight rudder and stern-post, I wish to point out that this invention is equally
applicable to curved stern-posts.
For the purpose of facilitating the shipping, and more especially for unshipping a
rudder constructed according to this present invention, I provide a cord, d, which
is passed from inside the boat over a pulley, d, on the stern-post, and made fast to
near the foot of the rudder. Two of these cords and pulleys may be used, one set on
each side of the rudder.
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. The combination, in a rudder-attachment, of a groove; bar; and pivotted
rudder-guide.
2. The combination, in a rudder-attachment, of a groove; a bar to which the rudder
is hinged, adapted to engage therewith; and a pivotted rudder-guide upon the stern-
post substantially as described with reference to the accompanying drawings.
3. The combination, in a rudder-attachment, of a T-bar fixed upon and pro-
jecting from the stern-post; a groove hinged to the rudder and adapted to engage
with said T-bar and a pivotted rudder-guide; substantially as described.
4. The combination of rudder; rudder-attachment; pivotted rudder-guide; cord ;
and pulley, substantially as described.
