Sealed the 13th May 1862, and dated the 18th November 1861.
PROVISIONAL SPECIFICATION left by the said Martin. Dadd. Rogers
at the Office of the Commissioners of Patents, with his Petition, on the
18th November 1861.
·I, MARTIN DADD ROGERS, of 2, Bow Lane Cottages, Saint Leonard's Road,
Bromley; in the County of Middlesex, do hereby declare the nature of the
said Invention-for "AN IMPROVED CHAIN CABLE STOPPER OR CONTROLLER," to be
as follows:
This Invention is designed to assist the riding of ships at anchor, for fleeting
the cable, and securing every link thereof while heaving in the cable.. I pro-
pose to effect this by means of a metal frame fixed to the ship's deck near the:
hawse hole. This metal frame has a solid tongue or pawl hinged thereto from
above, and the under side of said pawl or tongue is hollowed out to the form.
of the links of the cable; the bottom of the frame is also grooved for the links
of the cable to slide in. The said pawl or tongue may be raised by a handle,.
so as to allow the cable to pass freely, but upon lowering said pawl or tongue.
the cable will be securely held at any moment and as easily and quickly.
released.
This Invention is applicable to chain cables used on land for raising and
lowering heavy weights or merchandize.

TO ALL TO WHOM THESE PRESENTS SHALL COME, I, MARTIN
DADD ROGERS, of 2, Bow Lane Cottages, Saint Leonard's Road, Bromley, in
the County of Middlesex, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Eighteenth day of November, 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 Martin Dadd Rogers, Her special licence that I, the said Martin
Dadd Rogers, my executors, administrators, and assigns, or such others as
I, the said Martin Dadd Rogers, 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 "AN
IMPROVED CHAIN CABLE STOPPER OR CONTROLLER," upon the condition (amongst
others) that I, the said Martin Dadd Rogers, 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 Martin Dadd Rogers, 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, that is to say :-
This Invention is designed to assist the riding of ships-at-anchor, for fleeting
the cable, and securing every_link thereof while heaving in the cable. I pro-
pose to effect this by means of a metal frame fixed to the ship's deck near the
hawse hole. This metal frame has a solid tongue or pawl hinged thereto from
above, and the under side of said pawl or tongue is hollowed out to the form
of the links of the cable; the bottom of the frame is also grooved for the links
of the cable to slide in. The said pawl or tongue may be raised by a handle,
so as to allow the cable to pass freely, but upon lowering said pawl or tongue
the cable will be securely held at any moment, and as easily and quickly
released.

page_text: This Invention is applicable to chain cables or chains used, on land for
raising and.lowering heavy weights or merchandize.
And in order to explain my said Invention as completely as possible, I now
proceed to describe the best means I am acquainted with; for carrying the
same into practical effect, reference being had to the illustrative Sheet of
Drawings accompanying these Presents, and to the numeral figures and letters
of reference marked thereon respectively, as follows:-
DESCRIPTION OF THE DRAWING.
Figure 1 is a side elevation of my improved chain cable stopper or con-
troller to be adapted near the hawse hole of ships; Figure 2, an end elevation
of same at A, Figure 1; Figure 3, a top plan view of said stopper; Figure 4
is a plan view of the under side of the tongue or pawl of the stopper; Figure 5;
a top plan of the frame, to which the aforesaid tongue or pawl is connected;
Figures 6, 7, 8, 9, respectively exhibit a side elevation, a top plan, an end,
view at B, Figure 7, and a section through C, D, at Figures 7 and 8 of my,
improved chain cable stopper or controller adapted for the cathead of a ship,
At each of the foregoing Figures I-employ similar letters of reference to
denote corresponding parts, in so far as such parts appear or can be seen at
each of such said Figures respectively.
With reference to Figures 1, 2, 3, 4, 5, A is a casting, the surface of which
is grooved out or recessed, as exhibited at Figure 5, to receive the links of a
chain cable; B is a tongue or pawl hinged to A at a; the under side of B is:
also grooved out or recessed as .at Figure 4, to receive the links of a chain
cable; Figure 2 exhibits the relative position of the grooves in the pieces A
and B; when the pawl B rests on A, the grooves b, b, receive the horizontal
links of the chain, and the grooves c, c, the vertical links; C is a lever hinged
to A at d; said lever is connected loosely to the pawl B by a piece of metal D.
fixed to the pawl B.
The operations of the above mechanism are as follows:-Suppose a chain
cable to be passed between the pawl B and the casting A, as denoted by the
dotted lines at Figure 3, and the pawl B to be lifted and held in the position
denoted by the dotted lines at Figure 1, and suppose also the aforesaid chain
to have an anchor connected to one end thereof, and the other end to be fixed
to the ship's windlass or capstan, the chain cable will be free to run or pay
out, but, upon lowering the pawl B into the position exhibited by the solid
lines at Figure 1, the links of the chain cable coming into contact with the
shoulders of the grooves b, b, and c, c, will be arrested thereby, and forcing the
pawl B tightly against the surface of A will securely hold the chain cable, and

page_text: thus relieve the windlass or capstan from having to sustain the entire strain. of
the chain cable. By this arrangement the chain cable may be payed out
instantly and stopped as quickly at any time.
With reference to Figures 6, 7, 8, 9, the arrangement of the parts and
operations thereof being substantially the same as those lastly described with
reference to Figures 1, 2, 3, 4, 5. Similar letters of reference are employed
to denote corresponding parts.
Although I have only described and represented the above arrangements as
adapted for the hawse holes and catheads of ships, they are equally applicable
to other parts of ships or on land where security in holding and the sudden
release of a chain are required.
Having now fully described and set forth the nature and object of my said
Invention of "An Improved Chain Cable Stopper or Controller," together
with the best means I am acquainted with for carrying the same into practical
effect, I hereby declare my Invention to consist in, and I claim, the modes
above described and represented of constructing a chain cable stopper or
controller.
In witness whereof, I, the said Martin Dadd Rogers; have hereunto
set my hand and seal, this Sixteenth day of May, in the year of our
Lord One thousand eight hundred and sixty-two.
MARTIN DADD ROGERS. (L.S.)
