" pattern designer " and WILLIAM RHODES BOOTLAND of Wesley Street, Silsden
also in the said County of York "Cashier" do hereby declare the nature of our
invention for IMPROVEMENTS IN STERNPOSTS OF VESSELS AND IN THE METHOD of
FIXING RUDDERS THERETO to be as follows:-
Hitherto it has been usual to fix rudders to vessels by means of stays and bands
fixed onto the sternpost. We propose to substitute for the ordinary stern post, a
sternpost and rudder-post combined, which may be made of wood iron steel or any
other metal. The rudder-post is made to slide into a socket in sternpost and may
be of wedge shape or any other shape. Fixed in the back of the rudder-post is a
rack, with which, by means of a pinion geared into it (or by other means) the
rudder and rudder-post may be raised or lowered as required through an opening
made in the deck at stern of vessel. In conjunction with the rack, we propose in
large vessels to use either pillars or what are known as shear legs with blocks or
pulley attached worked by means of chains or ropes of any description—to assist
in dealing with the rudder and rudder-post after being freed from the socket in
stern-post. To the pillars may be attached arms for steadying the rudder and
rudder-post. We also propose to attach the rudder to the rudder-post by means of
a pin passing almost through the entire length of the rudder from the false neck
in large rudders and from the head in small ones, and through the lugs on rudder-
post. The present form of rudder fixed by stays and bands may be used in

page_text: conjunction with our rudder-post. In small vessels the rudder-post may be made
with or without rack and can be raised by blocks on shearlegs or by other means.
The rudder-post may be made for convenience in one two or more pieces keyed
together. A lid is fastened on to the top of sternpost to prevent the rudder post
from rising in its socket. By means of flanges attached to a separate sternpost,
our invention can be attached to vessels now afloat.

3 Spring Place, Shearbridge Road, Bradford also in the said county of York
pattern-designer" and WILLIAM RHODES BOOTLAND of Wesley Street, Silsden,
also in the said County of York "Cashier" do hereby declare the nature of our
invention for IMPROVEMENTS IN STERNPOSTS OF VESSELS AND IN THE METHOD MEANS
OF FIXING RUDDERS THERETO, and in what manner the same is to be performed, to
be particularly described and ascertained in and by the following statement:
Hitherto it has been neual to fix rudders to the sternpost of vessels by means of
what are known as stays and bands: We substitute for combine with the ordinary
sternpost of a vessel a sternpost and rudder post combined which may be made of
iron, steel or any other kind of suitable metal or metals. The rudder-post is preferably
made to slide into a slot or groove made in the sternpost, which slot or groove may bo
of wedge shape or any other suitable shape fixed and in the back of the rudder-post
there is provided a rack with which by means of a pinion-wheel geared into it (or by
other means) the rudder-post and rudder (when attached) may be raised or lowered-
as required through an opening made in the stern of the vessel. In large vessels, in
conjunction with the rack and pinion wheel may be used (to assist in dealing with the
rudder-post and rudder (when attached) when being freed from, or slided into slot or
groove in said sternpost) either pillars, or what are known as sheerlegs with blocks or
pulley attached, through which is run a chain or rope. We attach the rudder to the
rudder-post by means of a pin passing nearly through the entire length of the rudder,
from the false neck in large rudders, and from the head in small ones, and through
the lugs on the rudder-post. The present form of rudder fixed by stays and bands
may be used in conjunction with our rudder-post. In small vessels or boats the
rudder-post may be made with or without the rack and can be raised by blocks on
sheer legs or by other means. The rudder-post may be made in one piece or for
convenience, in two pieces keyed together. A lid is fastened on to the top of the
sternpost to prevent the rudder-post from rising in the said slot or groove. By means
of flanges attached to a separate sternpost, our invention can be attached to vessels
and boats now afloat. Further description of our invention: We substitute for the
present eternpost a double stern post, that is, a sternpost as 6 in Fig. 1. and a
Fudderpoet as in Fig. I combined as shown in Fig. X on necompanying drawings.
Fig. 1 shewe the opening through which the rudderpost and rudder (when attached)
and chains (where used) may be freed from or slided into the slot or groove in sternpost.
The opening may be closed by plates, grating or by ether means. The method of
raising or lowering the said rudder post and rudder (when attached) is by means of
ninion i-in Fig. 1. noting on rack d in Fig. I

page_text: "That our Invention may be clearly understood we will now proceed to describe the same fully,
