page_text: LETTERS PATENT to Richard Archibald Brooman, of 166, Fleet Street,
in the City of London, Patent Agent, for the Invention of "IMPROVEMENTS
IN APPARATUSES FOR DRAWING IN AND PAYING OUT CHAIN CABLES, APPLICABLE
TO WINDLASSES AND CAPSTANS."-A communication from abroad by Jean:
Salette, of Marseilles, France.
Sealed the 19th September 1862, and dated the 19th March 1862.
PROVISIONAL SPECIFICATION left by the said Richard Archibald Brooman
at the Office of the Commissioners of Patents, with his Petition, on the
19th March 1862.
I, RICHARD ARCHIBALD BROOMAN, of 166, Fleet Street, in the City of
London, Patent Agent, do hereby declare the nature of the said Invention for
"IMPROVEMENTS IN APPARATUSES FOR DRAWING IN AND PAYING OUT CHAIN CABLES
APPLICABLE TO WINDLASSES AND CAPSTANS," (communicated to me from abroad.
by Jean Salette, of Marseilles, France,) to be as follows:-
This Invention consists in constructing apparatus for drawing in and paying
out chain cables in the following manner :-Catches, free to rise and fall in
guides under the action of levers, are placed round the internal circumference
of the frame of the apparatus, the number of catches being regulated according
to the size of the apparatus or the size of the chain to be worked. These

page_text: levers are mounted on the same axes as longer levers which extend outside
the apparatus and terminate in rings. When heaving in, handspikes are
inserted in the rings, and as the apparatus is thereby caused to revolve the
catches become raised as they approach the chain and act upon it. To prevent
noise in the working of the apparatus, the long levers are divided from one
another by two rings on the apparatus.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Richard Archibald Brooman, in the Great Seal Patent
Office on the 19th September 1862.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, RICHARD
ARCHIBALD BROOMAN, of 166, Fleet Street, in the City of London, Patent
Agent, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters,
Patent, bearing date the Nineteenth day of March, in the year of our Lord
One thousand eight hundred and sixty-two, in the twenty-fifth year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto me, the
said Richard Archibald Brooman, Her special licence,, that I, the said
Richard Archibald Brooman, my executors, administrators, and assigns, or
such others as I, the said Richard Archibald Brooman, 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 APPARATUSES
FOR DRAWING IN AND PAYING OUT CHAIN CABLES, APPLICABLE TO WINDLASSES AND
CAPSTANS," (a communication from abroad by Jean Salette, of Marseilles,
France) upon the condition (amongst others) that I, the said Richard
Archibald Brooman, 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 Richard Archibald Brooman, do hereby
declare the nature of the said Invention, and in what manner the same is to

page_text: be performed, to be particularly described and ascertained in and by the
following statement thereof, reference being had to the Drawings hereunto.
annexed, that is to say:-
.
This Invention consists in constructing, apparatuses for drawing in and paying
5 out chain cables in the following manner:-Catches, free to rise and fall in
guides under the action. of levers, are placed round the internal circumference
of the frame of the apparatus, the number of catches being regulated according
to the size of the apparates or the size of the chain to be worked... These
levers are mounted on the same axes as longer levers which extend outside
the apparatus, and terminate in rings. When heaving in handspikes are
inserted in the rings, and as the apparatus is thereby caused to revolve, the
catches become raised as they approach the chain and act upon it.
Figure 1 of the accompanying Drawings is a view of an apparatus con-
structed according to this Invention showing a chain cable over it free to run
out through the forward hawse hole and disengaged from the hawse hole on
the deck above the chain hold; Figure 2 is an external view of the apparatus
which is composed of two plates a and b, in juxtaposition to one another.
The plate a carries ribs in which there are grooves for the passage of catches c.
At or about the centre of the ribs, levers, or cams d, d, are placed, the ends of
which enter an aperture formed in the centre of each catch c; the other
plate 6 is placed against the first to form the apparatus. On the axis of the
cams d, and extending outside the plates, levers f are fixed, the forward or
backward motion of which causes the cams d to move inwards or outwards,
and with them the catches c. There is a ring at the end of each of the levers f.
At the moment of paying out the cable, a handspike is inserted in one of the
rings to facilitate the motion or the stopping, the chain being always ready to
be paid out or hove in. To prevent the noise which would arise from the
independence of the levers f, they can be made dependent on one another by
two rings C, C, as shewn at Figure 2. The result is that no noise is heard,
and that in working or acting on any one of the levers f, all the others work
at the same time as well as all the catches. The chain may be stopped from
running out at any moment by means of a stopper or gripper 9, placed in the
lower part of the hawse hole in the chain hold.
1.
And having now described the nature of the said Invention, and in what
manner the same is to be performed, I declare that I claim:-
First, the employment in apparatus for drawing in and paying out chain
cables applicable to windlasses and capstans of a series of grooves and catches
acted on by cams and levers in manner herein-before described.

page_text: Second, the employment of a sliding stopper or gripper placed below the
deck hawse hole for stopping or checking the passage of chain cables as
berein-before described.
Third, the employment of rings for causing the levers to work together in
manner and for the purposes herein-before described.
In witness whereof, I, the said Richard Archibald Brooman, have here-
unto set my hand and seal, this Nineteenth day of September, One
thousand eight hundred and sixty-two.
R. A. BROOMAN. (L.S.)
