IMPROVEMENTS ADRADATIS POR PROPELLING AND STEERING VESSELS
Year: 1865

page_text: LETTERS PATENT to Jonathan Jopling, of Bishopwearmouth, in
County of Durham, Smith, for the Invention of "IMPROVEMENTS
ADRADATIS POR PROPELLING AND STEERING VESSELS."
Sealed the 24th November 1865, and dated the 30th May 1865.
PROVISIONAL SPECIFICATION left by the said Jonathan Jopling at
the Office of the Commissioners of Patents, with his Petition, on the
80th May 1865.
I, JONATHAN JOPLING, of Bishopwearmouth, in the County of Durham,
Smith, do hereby declare the nature of the said Invention for "IMPROVEMENTS
IN APPARATUS FOR PROPELLING AND STEERING VESSELS," to be as follows:-
This apparatus consists of a fan or fanner wheel fixed on a vertical shaft
and made to rotate within a circular case. The case, however, is open for
about one-half of its circumference to allow the water to pass freely out after
it has entered its centre. For turning the vessel or going astern, this will be
accomplished by causing the case to revolve until the opening in it allows the
water to escape in the direction desired, it will thus not be necessary to reverse
the engines, nor is any rudder required as the case is to be moved instead.
The apparatus may be fixed on the stern post, and the shaft pass up the
rudder trunk and driven as may be desired.
The Invention will be fully understood by the annexed Drawings. Figure 1
is a longitudinal section of the apparatus, and Figure 2 is a plan of the fan or
fanner wheel and circular case. A is the fan or fanner wheel mounted on a
vertical shaft B. C is the case in which the wheel A rotates; the case is

page_text: keyed on a hollow shaft D, the upper end of which carries a wheel E for
turning the shaft and the case C. The wheel A may have two, three, or more
arms or blades.
.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Jonathan Jopling in the Great Seal Patent Office on
the 30th November 1865.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JONATHAN
JOPLING, of Bishopwearmouth, in the County of Durham, Smith, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Thirtieth day of May, in the year of our Lord
One thousand eight hundred and sixty-five, in the twenty-eighth year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto me, the
said Jonathan Jopling, Her special licence that I, the said Jonathan Jopling,
my executors, administrators, and assigns, or such others as I, the said
Jonathan Jopling,
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
APPARATUS FOR PROPELLING AND STEERING VESSELS," upon the condition (amongst
others) that I, the said Jonathan Jopling, my executors or administrators, by
an instrument in writing under my, 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 Jonathan Jopling, 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 thereof, reference being had to the Drawings hereunto annexed,
that is to say :-
+
This apparatus consists of a hollow vertical shaft, on which is fixed, a
circular case, open in the centre to allow the water to enter, and also open for
.about one-third more or less of its circumference to allow the water to pass
freely out. Inside the hollow shaft rotates another vertical shaft, on which is
fixed a fan or fanner wheel having 2, 3, or more arms, fans, or blades,
which when in motion cause the water to pass freely out of the case. For

page_text: turning the vessel or going astern, or altering the direction of the vessel's motion,
this will be accomplished by causing the hollow shaft with the case to revolve
or turn until the opening in its circumference allows the water to escape in
the direction desired; it will thus not be necessary to reverse the engines, nor is
any other rudder required. The apparatus may be fixed near the stern post,
and the shafts pass up where the rudder trunk usually is. The fan wheel
shaft may be driven from above or below the circular case as may-be desired.
The Invention will be fully understood by the annexed Drawings. Figure 1
is a side elevation, and Figure 2 an end elevation, both partly in section of
the apparatus. Figure 3 is a plan of the fan or fanner wheel, and Figure 4
a plan of the case. Figure 5 is a plan shewing the wheel fitted in the
circular case. A is the fan or fanner wheel mounted on a vertical shaft B.
C is the case in which the wheel A rotates; the case is secured to a hollow
vertical shaft D, the upper end of which carries a wheel E for turning the
shaft and the case C. The fanner wheel A may have two, three, or more
arms, blades, or fans. F, F, are cranks on the fan wheel shaft B, which are
driven from the engine placed in any convenient part of the vessel. I do not,
however, confine myself to this means of communicating rotary motion to the
shaft B, as other well known means may be adopted.
And having now described the nature of my said Invention, and in what
manner the same is to be performed, I declare that I claim, constructing
apparatus for propelling and steering vessels consisting of a fan or fanner
wheel fixed on a vertical shaft and made to rotate within a movable circular
case, substantially as herein-before described and represented in the accom-
panying Drawings.
In witness whereof, I, the said Jonathan Jopling, have hereunto set
my hand and seal, this Twenty-fifth day of November, One thousand
eight hundred and sixty-five.
Signed, sealed, and delivered by the.
above-named Jonathan Jopling
in the presence of
Wч. MOORE,
Solicitor,
Sunderland.
