IMPROVE- MENTS IN PADDLE WHEELS
Year: 1869

page_text: LETTERS PATENT to Samuel Bateman, of Asnière, near Paris, in the
Empire of France, Manufacturer, for the Invention of "IMPROVE-
MENTS IN PADDLE WHEELS."
Sealed the 22nd June 1869, and dated the 5th January 1869.
PROVISIONAL SPECIFICATION left by the said Samuel Bateman at the
Office of the Commissioners of Patents, with his Petition, on the
6th January 1869.
I, SAMUEL BATEMAN, of Asnière, near Paris, in the Empire of France,
Manufacturer, do hereby declare the nature of the said Invention for
"IMPROVEMENTS IN PADDLE WHEELS," to be as follows, that is to say:-
My Invention consists in placing round the wheels for moving vessels
and other floating bodies moveable paddles, consisting of two parts
united together; one part, placed beyond the axis of oscillation relatively
to the centro is the paddle properly so called, it carries a joint at its
outer end; the second part placed between the axis of oscillation, and
the centre of the wheel has also a joint at its inner end. Each paddle is

page_text: jointed to the following one by a connecting rod passing from the inner
joint of one paddle to the outer joint of the other, or by any other
suitable means. The whole is arranged so that when one paddle is in
a radial position the following one is in an inclined position, and
reciprocally. The action of the paddles is obtained by means of the 5
resistance of the water.
SPECIFICATION in
pursuance of the conditions of the Letters Patent,
filed by the said Samuel Bateman in the Great Seal Patent Office
on the 5th July 1869.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, SAMUEL
BATEMAN, of Asnière, near Paris, in the Empire of France, Manu-
facturer, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Пcr
Letters Patent, bearing date the Fifth day of January, in the year of
our Lord One thousand eight hundred and sixty-nine, in the thirty-
second year of Her reign, did, for Herself, Her heirs and successors,
give and grant unto me, the said Samuel Bateman, Her special licence
that I, the said Samuel Bateman, my executors, administrators, and
assigns, or such others as I, the said Samuel Bateman, my executors,
administrators, and assigns, should at any time agree with, and no
others, from time to time and at all times thereafter during the term
therein expressed, should and lawfully might make, use, exercise, and
vend, within the United Kingdom of Great Britain and Ireland, the
Channel Islands, and Isle of Man, an Invention for "IMPROVEMENTS IN
PADDLE WHEELS," upon the condition (amongst others) that I, the said
Samuel Bateman, my executors or administrators, by an instrument in
writing under or their, or one of their hands and seals, should
particularly describe and ascertain the nature of the said Invention, and
in what manner the same was to be performed, and cause the same to
be filed in the Great Seal Patent Office within six calendar months
next and immediately after the date of the said Letters Patent.
NOW KNOW YE, that I, the said Samuel Bateman, do hereby declare
the nature of my said Invention, and in what manner the same is to
be performed, to be particularly described and ascertained in and by
the following statement, reference being had to the Drawing hereto

page_text: annexed, and to the ngurus and letters marked thereon, that is to
say:-
My Invention consists in placing round the wheels for moving vessels
and other floating bodies moveable paddles, consisting of two parts
united together; one part placed beyond the axis of oscillation relatively
to the centre is the paddle properly so called, it carries a joint at its
outer end; the second part placed between the axis of oscillation, and
the centre of the wheel has also a joint at its inner end. Each paddle is
jointed to the following one by a connecting rod passing from the inner
joint of one paddle to the outer joint of the other, or by any other
suitable means. The whole is arranged so that when one paddle is in
a radial position the following one is in an inclined position and
reciprocally. The action of the paddles is obtained by means of the
resistance of the water. By this improved mode of construction of
paddle wheels the whole of their working power is made available.
To make the Invention better understood I will proceed to describe it
by reference to the accompanying Drawing, in which Figure 1 is a
section on the line A', B', of Figure 2, which is a front elevation of a
paddle wheel constructed according to my improvements; and Figures 3
and 4, details of the buffer.
The paddle A, A, properly so called consists of a sheet or plate of
metal or wood; it is jointed at C to a shaft M, the ends of which are
fixed in a suitable manner to the framework of the wheel R; at tho
inner end of the wheel each paddle is provided with a prolongation O, D,
terminated by a buffer D; at the outer sido each paddle is formed with a
joint B, united by a connecting rod E to another joint F placed on the
prolongation C, D, of the next paddle; all the paddles are thus united
one to another, and the length of the rods is so regulated that one
paddle is forced to incline in turning on the shaft M. This paddle acts
on the two connecting rods E, to which it is jointed at B and F in
such a manner as to draw into a radial position the paddle which
precedes it and that which follows it. To insure greater firmness to
the paddle when under the action of the water it is drawn into this
radial position; the buffer D, Figures 3 and 4, made of washers of india-
rubber or other elastic material, strikes against an abutment G fixed to
the framework of the wheel by means of two cranips H, and by this
means the paddle becomes fixed.

page_text: The action of a wheel thus constructed and set in motion in the water
is as follows:-The paddle entering the water in its radial position will
incline under the action of the resistance of the water, and will take an
oblique direction, the two paddles next it being brought back to their
radial position. In continuing its movement the paddle meets with less 5
resistance, and recovers its radial position from the action of the move-
ment of the preceding paddle, which becomes inclined as it passes
through the water, and so on for all the paddles.
Having now described the nature of my said Invention, and the
manner of performing the same, I wish it to be understood that I do not 1
confine myself to the precise details herein laid down, as they may he
varied without departing from the principle of my Invention; but what
I claim is,-
Firstly. The improved construction of wheels with moveable paddles
arranged and united together in such a manner that one of the paddles 1
becoming inclined by the action of the resistance of the water, the two
paddles next it are drawn into their radial or normal position, as herein-
before described and represented in the accompanying Drawing.
Secondly. The combination of oscillating paddles furnished with
buffers and connecting rods jointed to the next paddles, as herein-before 20
described.
In witness whereof, I, the said Samuel Bateman, have hereto
set my hand and seal, this Second day of July One thousand
eight hundred and sixty-nine.
