AN IMPROVED METHOD OF PROPELLING VESSELS THROUGH WATER
Year: 1838

page_text: TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JULIAN
AUGUSTUS TARNER, of Henry Street, Liverpool, in the County of Lancaster,
Architect, send greeting.
WHEREAS Her present most Excellent Majesty Queen Victoria, by Her
Letters Patent under the Great Seal of Great Britain, bearing date at West-
minster, the Eighteenth day of January, in the first year of Her reign, did, for
Herself, Her heirs and successors, give and grant unto me, the said Julian
Augustus Tarner, Her especial license, full power, sole privilege and authority,
that I, the said Julian Augustus Tarner, my exors, admors, and assigns, or such
others as I, the said Julian Augustus Tarner, my exors, admors, or assigns,
should at any time agree with, and no others, from time to time and at all
times during the term of years therein expressed, should and lawfully might
make, use, exercise, and vend, within England, Wales, and the Town of
Berwick-upon-Tweed, my Invention of "AN IMPROVED METHOD OF PROPELLING
VESSELS THROUGH WATER;" in which said Letters Patent is contained a proviso
that I, the said Julian Augustus Tarner, shall cause a particular description of
the nature of my said Invéntion, and in what manner the same is to be
performed, to be enrolled in Her said Majesty's High Court of Chancery within
six calendar months next and immediately after the date of the said in part
recited Letters Patent, as in and by the same, reference being thereunto had,
will more fully and at large appear.
NOW KNOW YE, that the object sought to be obtained by this Invention con-
sists in propelling vessels on canals and other waters without creating that violent
swell or wave caused by the ordinary mode of propelling with paddle wheels at

page_text: cach side of the vessel, which is far injurious to the banks of canals and other
confined navigations, as in a great measure to exclude the use of steam boats
of such construction thereon, more particularly where they are not protected by
stone or brick walls. Now tho object of this my Invention is to remove such
objection, which I proposo to effect in the following manner, and which is more
fully described by the Specification in connection with the Drawings hereunto
annexed.
DESCRIPTION OF THE INVENTION OF JULIAN AUGUSTUS TARNER, ENTITLED "AN
IMPROVED METHOD OF PROPELLING VESSELS THROUGH WATER."
Which said description refers particularly to the Plans or Drawing hereunto
annexed, and which said Plans or Drawings must be taken to explain and
form a part of this Specification.
W is a paddle wheel or propeller, which may be be of any form or construc-
tion, proposed to be worked by steam or other motive power between the sides
of a boat or vessel so constructed as to possess sufficient buyoyancy to enable the
said paddle wheel or propeller to work on and under the level of the water L,
where its power of propelling the said boat or vessel is obtained. W is con
tained in a paddle box or chamber B, which may be made and used air-tight
or otherwise, as found most convenient; the part or portion of the same in the
front F being rounded or splayed so as to admit of a free supply of water
to the said paddle wheel or propellers when in use. Qis what I call my wave-
queller, constructed so as to be moveable or stationery, as may be found most
beneficial, with the point of the same P placed near the outside edge of the
floats or propellers, in order to prevent any wave rising from the same when
the said paddle wheel or propellers are set in motion. The back water
(commonly so called), which is lifted by the said paddle wheel or propellers
between the point P of the said wave-queller and the ring of the paddle wheel R,
during its progress of working, is thrown between the top of the said wave-
queller and the after part of the said paddle box or chamber, and by its own
gravity, and the velocity given it by the said wheel, is discharged through the
back-water channel C, C, into the canal or water at the stern of the boat; and
the water thrown back by the said paddle wheel or propellers when in action
is forced or pressed under the said wave-queller, which operation propels
the vessel through the water, and obviates or does away with the wave or swell
so injurious to the banks of narrow navigations.
Now I claim as my Invention, separately, distinctly, and collectively, the
aforesaid paddle box or chamber, made or constructed in any form similar
to the accompanying Drawings and this Specification, whether the same may be

page_text: used air-tight or otherwise, (with any machinery or apparatus therein) for the
purpose of propelling any vessel or vessels through water; also that the afore-
said wave-queller, and the back-water channel, as herein-before described.
And I also further claim the said wave-queller, whether the bottom of the
same (J) is used on a level with the water on which the vessel floats, or
above or below the level of the said water, or at any angle or inclined plane
with the level of the said water, or placed in any other situation or position;
together with the aforesaid back-water channel, at whatever angle or
inclined plane the same also may be used, and whether the after end of the
said back-water channel through which the back water, lifted by the afore-
said paddle wheel or propeller, is discharged, may be placed or used
below the level of the water on which the vessel floats, or on the level of the
said water, or above the level of the said water, or in any other situation
or position to which the same may be applied. As also the aforesaid paddle
box or chamber, the said wave queller, and also the said back-water channel,
as before described, whether used singly, in pairs, or otherwise.
