Year: 1861

page_text: LETTERS PATENT to John Walter Friend, of Freemantle, Southampton,
for the Invention of "IMPROVEMENTS IN APPARATUS FOR REGISTERING THE.
Am DramANGES DIN BY SUIDS AT SEA "
Sealed the 6th June 1862, and dated the 13th December 1861.
PROVISIONAL SPECIFICATION left by the said John Walter Friend at
the Office of the Commissioners of Patents, with his Petition, on the
13th December 1861.
I, JOHN WALTER FRIEND, of Freemantle, Southampton, do hereby declare
the nature of the said Invention for "IMPROVEMENTS IN APPARATUS FOR
REGISTERING THE DEPTH AND FLOW OF LIQUIDS, AND THE DISTANCES RUN BY SHIPS
AT SEA," to be as follows (that is to say):-
My Invention has reference to improvements in apparatus for registering
the depth and flow of liquids, and the distances run by ships at sea, and con-
sists of a fan or paddle wheel mounted upon spindle bearings (within a suitable
case furnished with waterways for conducting the fluid to the floats or paddles)
-in-connection with revolving graduated wheels or dial plates, through the
intervention of tangent tooth and pinion gear, so arranged-that, upon the fan
or paddle wheel being actuated by the passage of the water through the instru-
ment, the graduated wheels or dial plates will be caused to register results

page_text: corresponding thereto, for the purpose of indicating the depth of water at sea,
the speed or distances run by ships or other vessels, or the amount of fluid
otherwise passed through the apparatus; the said apparatus when employed
as a log being curved and weighted, so as to maintain its proper position in
the water, as also provided with side wings for keeping the same constantly
submerged.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said John Walter Friend in the Great Seal Patent Office on the
13th June 1862.
"
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JOHN
WALTER FRIEND, of Freemantle, Southampton, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Thirteenth day of December, in the year of our
Lord One thousand eight hundred and sixty-one, in the twenty-fifth year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto me,
the said John Walter Friend, Her special licence that I, the said John Walter
Friend, my executors, administrators, and assigns, or such others as I, the said
John Walter Friend, 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, exer-
cise, and vend,..within the United Kingdom of Great Britain and Ireland, the
Channel Islands, and Isle of Man, an Invention for "IMPROVEMENTS IN APPA-
RATUS FOR REGISTERING THE DEPTH AND FLOW OF LIQUIDS, AND THE DISTANCES RUN
BY SHIPS AT SEA," upon the condition (amongst others) that I, the said John
Walter Friend, 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 John Walter Friend, do hereby declare
the nature of my said Invention, and in what manner the same is to be per-
formed, to be particularly described and ascertained in and by the following
statement, and the Drawings therein referred to, that is to say:-
My Invention has reference to improvements in apparatus for registering
the depth and flow of liquids, and the distances run by ships at sea, and con-

page_text: sists of a fan or paddle wheel mounted upon spindle bearings (within a suitable
case furnished with waterways for conducting the fluid to the floats or paddles);
in connection with revolving graduated wheel or dial plates, through the inter-
vention of tangent tooth and pinion gear, so arranged that, upon the fan of
paddle wheel being actuated by the passage of the water through the instru-
ment, the graduated wheel or dial plates will be caused to register "results
corresponding thereto, for the purpose of indicating the depth of water at sea;
the speed or distance run by ships or other vessels, or the amount of fluid
otherwise passed through the apparatus; the said apparatus when employed
as a log being curved and weighted, so as to maintain its proper position in
the water, as also provided with 'side wings for keeping the same constantly
submerged.
And in order that my said Invention may be more fully understood and
readily carried into effect, I now proceed to describe it
the aid of the accom-
panying Drawings, reference being had to the letters and figures thereon
marked (that is to say):-
=
Fig. I. represents a top or plan view of my improved log for registering the
distances run by ships at sea; Fig. 2, a side elevation; Fig. 3, a transverse
vertical section taken through the dotted lines in Figures 1 and 2; Fig. 4, a
vertical front view of my improved deep-sea lead, showing a portion of the
cuter case removed, as also the ordinary sinking weight thereof, for the pur-
pose of enabling the working parts of the apparatus to be more clearly shown;
Fig. 5, a top or plan view of the same; Fig. 6, a top or horizontal view of an
improved water meter for ascertaining and registering the flow of liquids; and
Fig. 7, a corresponding view showing the dial plate or.index cover removed. In
each Figure the same letters of reference denote similar corresponding parts.
A, A, outer case or cover enclosing the mechanism; B, B, passages or
openings through which the water is admitted to the instrument; C, C, outlet
openings or passages for the escape of the same; D, D, registering dial plates
or wheels, graduated and furnished with numerals necessary for indicating cor-
rectly the action of the instrument when in operation; E, E, motive screw
wheel or flyer, communicating motion to the said graduated numeral plates or
dials through the medium of tangent tooth and pinion gear F, F', as shown;
G, G', spindles and spindle bearings upon which_the_same_work;-H,-¯‚—
curved passages or channels through which the water is transmitted to the
motive screw wheel or flyer in the required direction indicated by the arrows;
I, I, wing plates obliquely secured to the sides of the registering log, so as to
maintain the instrument when in use in a submerged position.
Having now fully described and ascertained the nature of this-my said

page_text: Invention, and the manner in which the same is to be performed and carried
into effect, I would have it clearly understood that I do not intend to confine
myself to the precise details herein-before described, as the apparatus may
receive such other modifications or arrangements as may be found necessary,
or the same may be otherwise varied without departing from the general prin-
ciple of this my said Invention; but that which I do claim as new and of my
said Invention is, the general construction and arrangement of the said mecha-
nism in combination with the revolving dial or index plates, in the manner
and for the purposes herein-before set forth and described.
In witness whereof, I, the said John Walter Friend, have hereunto
set my hand and seal, this Eleventh day of June, in the year of
our Lord One thousand eight hundred and sixty-two.
JOHN WALTER FRIEND. (L.S.)
