Saint George's in the East, in the County of Middlesex, and Martin
Dadd Rogers, of No. 2, Bow Lane Cottages, Saint Leonard's Road,
Bromley, in the County of Middlesex; for the Invention of "AN IMPROVED
CHAIN CABLE CONTROLLER FOR SHIPS' WINDLASSES, TO PREVENT RIDING OF
ADID IN PAYING-OUT AND HEAVING-IN OF SAME.'
"
Sealed the 24th October 1861, and dated the 1st May 1861.
PROVISIONAL SPECIFICATION left by the said Thomas Alfred Kendal
and Martin Dadd Rogers at the Office of the Commissioners of Patents;
with their Petition, on the 1st May 1861.
We, THOMAS ALFRED KENDAL, of No. 108, Cowley Street, Saint George's
in the East, in the County of Middlesex, and MARTIN DADD ROGERS, of No. 2,
Bow Lane Cottages, Saint Leonard's Road, Bromley, in the County of Mid;
dlesex, do hereby declare the nature of the said Invention for "AN IMPROVED
CHAIN CABLE CONTROLLER FOR SHIPS' WINDLASSES, TO PREVENT RIDING OF CABLE
IN PAYING-OUT AND HEAVING-IN OF SAME," to be as follows:-
This Invention consists of an upright standard of metal, in which are.fixed
horizontally two strong studs or pins in a line with the centre of the barrel of
the windlass. The distance between said studs should be such that the links,
of the cable will pass freely between them, said studs being employed to
prevent riding of the cable during paying-out of same, or letting go the

page_text: anchor. The points of said studs should just clear the barrel of the windlass.
The aforesaid standard is fixed to the deck of the ship, and the height thereof
should be above the top of the barrel of the windlass, in order that the sides
of the standard above the aforesaid studs shall guide the cable from centre of
barrel, and thus prevent the cable riding whilst heaving-in same.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Thomas Alfred Kendal and Martin Dadd Rogers in the
Great Seal Patent Office on the 31st October 1861.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, THOMAS
ALFRED KENDAL, of No. 103, Cowley Street, Saint George's in the East, in
the County of Middlesex, and MARTIN DADD ROGERS, of No. 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 First day of May, in the year of our Lord One
thousand eight hundred and sixty-one, in the twenty-fourth year of Her reign,
did, for Herself, Her heirs and successors, give and grant unto us, the said
Thomas Alfred Kendal and Martin Dadd Rogers, Her special licence that
we, the said Thomas Alfred Kendal and Martin Dadd Rogers, our executors,
administrators, and assigns, or such others as we, the said Thomas Alfred
Kendal and Martin Dadd Rogers, our 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 CONTROLLER FOR SHIPS' WINDLASSES, TO PREVENT RIDING
OF CABLE IN PAYING-OUT AND HEAVING-IN OF SAME," upon the condition (amongst
others) that we, the said Thomas Alfred Kendal and Martin Dadd Rogers,
our executors or administrators, by an instrument in writing under our, 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 we, the said Thomas Alfred Kendal and Martin
Dadd Rogers, do hereby declare the nature of our 'said Invention, and in

page_text: 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 consists of an.upright standard of metal, in which are fixed
horizontally two strong studs or pins in a line with the centre of the barrel of
the windlass. The distance between said studs should be such that the links
of the cable will pass freely between them, said studs being employed to
prevent riding of the cable during paying-out of same, or letting go the
anchor. The points of said studs should just clear the barrel of the windlass.
The aforesaid standard is fixed to the deck of the ship, and the height thereof
should be above the top of the barrel of the windlass, in order that the sides
of the standard above the aforesaid studs shall guide the cable from centre of
barrel, and thus prevent the cable riding whilst heaving-in same.
In order to explain our said Invention as completely as possible, we now
proceed to describe the best means we are acquainted with for carrying the
same into practical effect, reference being had to the illustrative Sheet of
Drawings hereunto annexed, and to the numeral figures and letters of refer-
ence marked thereon respectively, as follows:-
DESCRIPTION OF THE DRAWING.
Figure 1 is a front elevation of a portion of the barrel of a ship's windlass,
shewing our improvements adapted thereto; Figure 2, a top plan view of
Figure 1 Figure 3, a transverse and vertical section on the line A, B, at
Figures 1 and 2; Figures 4 and 5, detached portions, herein-after particularly.
described and referred to; Figure 6 is a front elevation, Figure 7 a top plan
view, and Figure 8 a cross section, of the barrel of a ship's windlass; shewing
another mode of adapting our improvements thereto. At each of the foregoing
Figures we 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, and 5, A marks a portion of the
barrel of a ship's windlass, supported at its ends in the usual way, and fitted
with pawls and ratchets of the ordinary kind, as at B, Figure 2. C is a
piece of metal, having pins D, D, affixed to or formed thereon, said pins being
intended to serve the purpose of the "normans" commonly used in ships'
windlasses for preventing riding of the cable whilst paying-out and heaving-in
same, and serving also as a substitute for the "whelps" used for that purpose.
The piece C should be firmly secured to the ship's deck, so that the pins D, D,
come as near as may be in a horizontal line with the centre of the diameter
of the barrel of the windlass, and with the points of said pins clear of the

page_text: barrel, as exhibited. We would also observe that, in fixing the piece C to
the ship's deck, care should be taken to so fix it as that the pin nearest to the
pawl bit is distant about four or five inches from the line of the cable as it
passes from the barrel of the windlass through the hawse pipe at right angles
to the barrel, to prevent chafing of the cable. By this arrangement the cable
as it is wound around the barrel each turn or coil will be divided and kept
separate, and thus prevent riding of the cable, as before stated. Or, instead
of employing a piece of metal of the construction above described, .and in
which two pins or "normans" are fixed, the said pins or "normans"
made separate and distinct from each other, and fixed to. the deck of the ship
vertically at each side of the barrel of the windlass, as at Figures 6, 7, 8, the
top of said pins being as near as may be in a horizontal line with the centre
of the diameter of the barrel of the windlass, as exhibited.
may be
Having now fully described and set forth the nature and object of our said
Invention of "An Improved Chain Cable Controller for Ships' Windlasses, to
Prevent Riding of Cable in Paying-out and Heaving-in of same," together
with the best means we are-acquainted with for carrying the same into
practical effect, we would remark, in conclusion, that what we claim as our
Invention intended to be secured to us by the berein-before in part recited
Letters Patent, is the use of fixed "normans" or pins distinct and separate
from the barrel of a ship's windlass, for the purpose of preventing riding of
the cable in paying-out and heaving-in same, and by which the windlass is
always ready to let go or heave in the anchor.
In witness whereof, we, the said Thomas Alfred Kendal and Martin
Dadd Rogers, have hereunto set our hands and seals, this Twenty-
ninth day of October, in the year of our Lord One thousand eight
hundred and sixty-one.
