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 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 tee 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 nearly the top, round off the bottom corner of the tee-bar, and cut away the
central portions of the flanges of the said bar.
The rudder can then be shipped by introducing the tee bar into the groove at the
lowest point of the length from which the front flanges have been cut away. The
flanges at the top of the groove receive the upper half of the tee, and the weight of
the rudder takes it down into position.
Suitable stops are provided at either end of the attachment.

page_text: 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, 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-attach-
ments; 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 tee-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 tho 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 nearly the top, round off the bottom corner of the tec-bar, and cut
away the central portions of the flanges of the said bar.
The rudder can then be shipped by introducing the tee-bar into the groove at
the lowest point of the length from which the front flanges have been cut away.
The flanges at the top of the groove receive the upper half of the tee, and the weight
of the rudder takes it down into position.
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, 1 will proceed 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 application
of my invention to a rudder attachment as described in the specification of my Letters
Patent No. 6870, 5th June, 1885.
Fig. 1 illustrates in elevation the T-bar and the groove, the combination of which
constitutes my invention.
Fig. 2 is a side elevation shewing the application of my invention to a boat-stern
and rudder. The full lines shew the rudder shipped the dotted lines shew it partly
shipped, or unshipped.
Fig. 3 is a perspective view illustrating the act of shipping.

page_text: A is a metal groove fixed upon the face of the stern-post B.
The front flanges, a, of the groove are cut away near the top, forming a long
opening, a', at any point in which the nose of the T-bar, C, hinged to the rudder, D,
can be entered and brought to bear against the back, a³, of the groove.
The flanges, c, of the T-bar are also cut away, producing two vacant spaces, c², not
less in length that the closed top, a³, of the groove, and which they are adapted to
pass. The opposite edges of the spaces, c', are bevelled as are also the top edges of
the opening, a', in the groove-front, to assist such engagement.
A rudder is shipped according to this invention in the following manner.
It is held out over the stern-post in the position indicated in Fig. 3, and its
nose, c³, introduced into the long opening, a', and steadied there until said nose has
engaged in the lower part of the groove A below said opening.
The rudder is next pulled towards the stern-post until that part of the bar below
the spaces, c, bears against the top part, a³, of the groove. The rudder is then
allowed to drop, the pull towards the stern-post being still maintained. As the
lower part of the T-bar disappears into the opening, a', the upper part of said bar
will enter the top of the groove, and the rudder needs only to be allowed to drop to
effect its easy and proper shipment.
To unship a rudder fitted with my invention as above described the above process is
reversed.
I wish it to be distinctly understood that I do not confine myself to the modi-
fication of my invention illustrated in the accompanying figures and described in
connection therewith, inasmuch as the same may be varied without departing from
the scope of the invention. For instance, the relative positions of the groove and
T-bar may be reversed; the groove being hinged to the rudder and the T-bar fixed
upon the stern-post, in which case the spaces in the flanges of the T-bar would be
near the top thereof, and the opening in the groove near the bottom.
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 groove; bar; opening; and
spaces; substantially as described.
2. The combination, in a rudder-attachment, of groove fixed upon the stern-post ;
an opening formed in its front; and a T-bar hinged to the rudder, adapted to engage
in said groove, and having spaces in its flanges adapted to pass the top part of the
groove substantially as described with reference to the accompanying drawings.
3. The combination, in a rudder-attachment, of a groove hinged to the rudder, and
a T-bar fixed to and projecting from the stern-post, the groove being adapted, by
means of an opening formed in its front, to engage in spaces cut in the flanges of the
T-bar, and also to engage with the full-section part of the T-bar; substantially as
described.
