I, JOHN DAMPIER HICKMAN, of Portsmouth Road, Thames Ditton, in the County of
Surrey, Cycle Manufacturer and Engineer, do hereby declare the nature of invention
to be as follows:-
My invention relates to an extension, or novel application, of an invention described
and illustrated in a specification No. 6870 of 1885, which describes an improved
method of attaching rudders to the sterns of boats in such a way that they can be
readily shipped or unshipped, and at the same time be capable of yielding to any
obstacle they may be required to pass over.
the
According to this present invention, I make the rudder attachment of the same
sections and parts as described in the before mentioned specification, that is to say,
rudder is hung in any convenient way upon a bar which either slides in a groove
formed on or in the stern-post, or upon a bar projecting therefrom; but, instead of
making the grooves and bars straight, as illustrated in my said previous specification,
I bend them round a common centre, thereby rendering possible the application of my
said former invention to the round ends of canoe-shaped craft, as life-boats, which,
having bows and sterns alike, can advantageously have an attachment at each end, and
one rudder, to be transferred from end to end, or two, one to be shipped, and the other
unshipped.

My invention relates to an extension, or novel application, of an invention described
and illustrated in a specification No. 6870 of 1885, which describes an improved
method of attaching rudders to the sterns of boats in such a way that they can be
readily shipped or unshipped, and at the same time be capable of yielding to any
obstacle they may be required. to pass over.
According to this present invention,
sections and parts as described in the before-mentioned specification, that is to say, the
rudder is hung in any convenient way upon a bar which either slides in a groove formed
on or in the stern post, or upon a bar projecting therefrom; but, instead of making
the grooves and bars straight as illustrated in my said previous specification, I bend
them round a common centre, thereby rendering possible the application of my said
former invention to the round ends of canoe-shaped craft, as life-boats, which having
bows and sterns alike, can advantageously have an attachment at each end, and one
rudder to be transferred from end to end, or two, one to be shipped, and the other
unshipped.

In order that my invention, and the means by which it can be carried into practical
operation, may be thoroughly understood, I 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.
Fig. 1 is an elevation illustrating my invention as applied to a canoc; the rudder
shipped and hung, with a backward rake.
Fig. 2 is an elevation illustrating my invention as applied to a canoe. The rudder
is hung vertically and is shewn as unshipped.
A is the rudder, and B the bar bent to the same are as that of the groove C; that
of the stern post D upon which the latter is fixed, being struck to fit the groove.
The bar, B, is connected to the rudder hinge in any convenient way. An inter-
mediate web, b, is shewn in the drawings which is of a convenient width.
I provide a suitable stop, b¹, to prevent the rudder from dropping too low after it
has been shipped.
The relative positions of the bar and groove may be reversed.
Having now particularly described and illustrated the nature of my said invention,
and in what manner the same is to be performed, I declare that what I claim is ;-
In a detachable rudder attachment; the combination of rudder hinge, with a bar
fitting into a groove, both bar and groove bent to the same arc substantially as
described with reference to the accompanying figures.
