IMPROVEMENTS IN TUG AND OTHER HOOKS
Year: 1855

page_text: LETTERS PATENT to Charles Jared Hunt, of the Willows, Mitcham, in
the County of Surrey, for the Invention of "IMPROVEMENTS IN TUG AND
OTHER HOOKS."
Sealed the 26th October 1855, and dated the 10th May 1855.
PROVISIONAL SPECIFICATION left by the said Charles Jared Hunt at
the Office of the Commissioners of Patents, with his Petition, on the
10th May 1855.
I, CHARLES JARED HUNT, of the Willows, Mitcham, in the County of
Surrey, do hereby declare the nature of the Invention for "IMPROVEMENTS IN
TUG AND OTHER Hooкs" to be as follows:-
This Invention has for its object improvements in tug and other hooks, with
a view to make them open out more fully, and consequently to release when
subject to a direct pull. For this purpose a tug or other hook is made of three
parts, which are hinged or pin-jointed together. The stem, which constitutes
one part of a hook, is made with a swivel eye or otherwise, as may be desired.
At the lower end the second part of the hook which receives the strain is
connected by a pin joint, and to this part the third part is pin-jointed. The
other end of this third part is made in such manner as to be securely held to
the stem of the hoop by means of a cylinder, which is capable of rotating
pear the upper part of the stem, and it is constantly pressed on by a spring.

page_text: So long as the hook is in use the parts are all held securely, but immediately
on requirement by moving up the cylinder, and moving it partly round, the
point of the hook will be released, and by reason of the hook being in three
parts it will open out, so as to completely release whatever it may previously
have held.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Charles Jared Hunt in the Great Seal Patent Office on the
10th November 1855.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, CHARLES
JARED HUNT, of the Willows, Mitcham, in the County of Surrey, send
greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Tenth day of May, in the year of our Lord One
thousand eight hundred and fifty-five, in the eighteenth year of Her reign,
did, for Herself, Iler heirs and successors, give and grant unto me, the said
Charles Jared Hunt, Her special licence that I, the said Charles Jared Hunt,
my executors, administrators, and assigns, or such others as I, the said Charles
Jared Hunt, 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 TUG AND OTHER
Hooks," upon the condition (amongst others) that I, the said Charles Jared
Hunt, by an instrument in writing under my hand and seal, 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 Charles Jared Hunt, do hereby declare
the nature of the 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 thereof (that is to say):-
This Invention has for its object improvements in tug and other hooks, with
a view to make them open out more fully, and consequently to release when
subject to a direct pull. For this purpose a tug or other hook is made of three
parts, which are hinged or pin-jointed together. The stem, which constitutes

page_text: one part of a hook, is made with a swivel eye or otherwise, as may be desired.
At the lower end the second part of the hook which receives the strain is
connected by a pin joint, and to this part the third part is pin-jointed. Tho
other end of this third part is made in such manner as to be securely held to
the stem of the hook by means of a cylinder, which is capable of rotating near
the upper part of the stem, and it is constantly pressed on by a spring. So
long as the hook is in use tho parts are all held securely, but immediately on
requirement, by moving up the cylinder, and moving it partly round, the point
of the hook will be released, and by reason of the hook being in three parts it
will open out, so as to completely release whatever it may previously have held.
Having thus stated the nature of my said Invention, I will proceed more
fully to describe the manner of performing the same.
DESCRIPTION OF THE DRAWING.
Figure 1 shows a side view, and Figure 2 is a section, of a tug or hook
constructed according to my Invention.
a is the stem, to which the proper eye or swivel is applied, or other form of
instrument by which the hook is to be applied, to the stem a; the intermediate
piece b is attached by a pin joint, and to the intermediate piece is attached the
part c, and this part c at its other end is to be formed and arranged in respect
to the other parts in such manner that it may be held securely when in use, and
yet capable of being easily and readily released when it is required to release
the trace or other instrument held by the tug or hook. For this purpose I
prefer to use the hoop or band d, which can turn freely round on the stem, and
between it and the eye e fixed thereto. This hoop has a notch in it, so that
when this notch is at a distance from the point of the hook, the hook will be
held secure; but when by turning this hoop the notch comes opposite the point
of the hook, the hook will be released, and the trace or other instrument
attached to or held by the hook will be readily freed by any strain thercon. The
hoop has on it a projection a, and the hoop is pressed towards the point of the
hook by a spring; hence, in use the hoop will bo retained from movement by
the part a entering the notch f on the fixed collar of the stem. In order to
release the point of the hook the hoop is moved back on the stem, so as to draw
the part out of the notch, and then the hoop can be readily moved round on
the stem, so as to bring the notch in the hoop opposite the point of the hook.
Having thus described the nature of my Invention, and the manner of
performing the same, I would have it understood that I am aware that tugs or
hooks have before in some cases been made each of two parts connected by a
pin joint at the bend or point where the strain when in use comes.
I do not

page_text: therefore claim such construction; but what I claim is, the construction of tugs
or hooks by a combination of parts a, b, c, as herein described.
In witness whereof, I, the said Charles Jared Hunt, have hereunto set
my
hand and seal, this Ninth day of November, in the year of our
Lord One thousand eight hundred and fifty-five.
Witness,
JNO. ALCOOK.
CHARLES JARED HUNT. (L.S.)
