My invention relates to an improved method of hanging rudders to their stern
posts, and more particularly to the way in which the rudder bands are fixed to the
rudder, the object of the invention being to bring the rudder-back closer to the
stern post than heretofore, and to enable it to be unshipped at any angle with
the stern:
In carrying out my invention, I form recesses in the back of the rudder, which
receive the knuckles of the rudder-straps and crooks:
Both crooks are joined, as closely as possible; to one bar, which is of any
convenient construction and of a suitable section to enter and be retained in a
vertical groove extending for about half the length of the stern post, where it
meets the keel strap.
A baffle is formed by extending the keel for

page_text: An Improved Method of Hanging Rudders.
I, THOMAS GEORGE TAGG, of the Island Boat Building Works, East Moulsey,
in the County of Surrey, Boat & Steam Launch Builder, 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 method of hanging rudders to their stern
posts, and consists more particularly in connecting the bands and adjacent parts to
the rudder in such a way that it can be brought back closer to the stern post than
has been practicable with the usual methods of hanging rudders, and be unshipped
at any angle with the stern.
In order that my invention, and the means by which the same can be carried
into practical effect, may be thoroughly understood, I will 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 there with, and in which like parts are marked
throughout the figures in which they occur with the same reference letter.
Fig. 1 is an elevation of a boat stern fitted according to my invention.
Figs. 2 and 3 illustrate my invention in elevation, the rudder being shewn
unshipped and opposite the stern post.
Fig. 4 illustrates a rudder, fitted with my invention, hung to the stern post.
Fig. 5 is a plan taken through a knuckle.
Figs. 6, 7, and 8 illustrate an alternative construction, according to which the
rod and sockets of the construction illustrated in the previous five figures are
replaced by a rod sliding in a groove on the face of the stern post.
A is the rudder, having a recess formed in its back edge extending from the eye
of one band to the eye of the other.
B, B are the rudder-bands.
C is an axial pin, the ends of which are fitted into the eyes of the rudder-bands
and capable of a free rotary motion in the sockets of the knuckles D which are
represented as three in number. Of course this number is variable.
E; E are interposed pieces of tube, or they may be made in one piece with the
knuckles D.
F, F, F are semi-tubular extensions of the knuckles D, to which they are
connected by webs G. These three continuations may be one continuous tube, as
also might the webs be one continuous web.
H is a rod projecting by means of a web h from the face of the stern. This part
is conveniently continued towards to the keel, at the junction with which an
extension I is produced which acts as a baffle for the protection of the helm.
According to the modification illustrated in Figs. 6, 7, and 8, there are only two
knuckles D, each entering a recess formed in the edge of the rudder to receive it.
A third recess, connecting the two former, receives the long central part of the
axial pin C, when the knuckles are not continuous.
J is a rod joined to the knuckles and entering a groove, or tube, K on the
stern post.
According to this construction, the knuckles D and the rod J are close together
instead of being connected by a web.

page_text: 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,
•
The combination of rudder-band-eyes, knuckles, and axial pin all recessed into
the back edge of the rudder, with a rod, or a tube, on the outer face of the said
knuckles and incorporated therewith, and a groove, or a rod, respectively upon the
stern post to receive the said rod, or tube; substantially as and for the purpose
hereinbefore described with reference to the accompanying drawings.
