IMPROVEMENTS IN CAPSTANS AND WINDLASSES
Year: 1846

page_text: TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JOHN
ROMBLEY, of Sunderland, Engineer, send greeting.
WHEREAS Her present most excellent Majesty Queen Victoria, by Her
Royal Letters Patent under the Great Seal of Great Britain, bearing date at
Westminster, the Eighth day of October, One thousand eight hundred and
forty-six, in the tenth year. of Her reign, did, for Herself, Her heirs and
successors, give and grant unto me, the said John Rombley, my exors, admors,
and assigns, Her especial licence, full power, sole privilege and authority, that
I, the said John Rombley, my exors, admors, and assigns, or such others as I,
the said John Rombley, my exors, admors, or assigns, should at any time
agree with, and no others, from time to time and at all times thereafter
during the term of years therein expressed, should and lawfully might make,
use, exercise, and vend, within England, Wales, and the Town of Berwick-
upon-Tweed, my Invention of "IMPROVEMENTS IN CAPSTANS AND WINDLASSES;"
in which said Letters Patent is contained a proviso that I, the said John
Rombley, shall cause a particular description of the nature of my said Inven-
tion, and in what manner the same is to be performed, by an instrument in
writing under my hand and seal, to be inrolled in Her said Majesty's High
Court of Chancery, within six calendar months next and immediately after the
date of the said in part recited Letters Patent, as in and by the same, reference
being thereunto had, will more fully and at large appear.
NOW KNOW YE, that in compliance with the said provise, I, the said
John Rombley, do hereby declare that the nature of my Invention, and the

page_text: manner in which the same is to be performed, are fully described and ascer-
tained in and by the following statement thereof, reference being had to the
Drawings hereunto annexed and to the figures and letters marked thereon,
that is to say-
And, in
My Invention consists of applying to the pinion or toothed wheel which
takes into and gives motion to the cog wheel on the barrel of a capstan or
windlass ratchets driven by suitable drivers, as hereafter explained.
order that the Invention may be most fully understood and readily carried
into effect, I will proceed to describe the Drawings hereunto annexed, in the
various Figures of which the same letters are used to indicate the same
that is to say:-

DESCRIPTION OF THE DRAWINGS.
Figure 1 shows an elevation of a capstan having my Invention applied
thereto. Figure 2 shows the means of obtaining motion to the pinion which
drives the bevelled cog wheel on the barrel. a is the barrel of a capstan;
6 is a bevelled cog wheel affixed on the barrel; c is a pinion which takes into
the wheel b and drives the same. The pinion c moves freely on the axis d
which is fixed in the standard e. And on the axis d there are two levers f, f,
one on either side of the pinion c, such levers carrying a series of drivers g, g,
as shown, there being a ratchet formed on or combined with each side of the
pinion into which the drivers 9 take as the levers are moved on the axis d, and
thus is the pinion caused to rotate and drive the wheel 6, and motion is com-
municated to the levers ƒ by means of the lever h moving on a fulcrum or
axis at i, the connecting rods j, j, connecting the levers f, f, with the lever h,
as is shown.

Figure 3 shows a front view, Figures 4 an end view in section, and Figure 5
some of the details separately, of my Invention as applied to windlasses. a is
the barrel of the windlass; b, the cog wheel thereon; c, the pinion with its
ratchets, all which are similar to the parts described in respect to the capstan,
but in this case the teeth of the wheel and pinion are not bevelled. Motion
is obtained to the pinion by means of the arms with the drivers g, the
levers f receiving motion from the levers 7 by connecting rods j, j, all which
will readily be understood on examining these Figures of the Drawings. Or
in place of having the ratchet within the pinion, as shown, they may be on
the face thereof; and, in place of having the drivers g and levers f, the levers f
may be attached to ratchet plates / which are forced up against the ratchets
on the faces of the pinion, thus producing clutch boxes. This arrangement
will readily be understood on examining Figures 6, 7, and 8, where a front

page_text: view, a plan, and an end view in section are shown of a windlass so arranged,
the parts of which are marked with the same letters of reference.
Having thus described the nature of my Invention, and the manner in
which the same is to be performed, I would have it understood that I do not
confine myself to the details as shown, provided the peculiar character of my
Invention be retained. But what I claim is, the applying the apparatus to
the pinion or wheel c, for giving motion to the wheel 6 on the barrel of a
capstan or windlass, as described.
In witness whereof, I, the said John Rombley, have hereunto set my
hand and seal, this Eighth day of April, in the year of our Lord
One thousand eight hundred and forty-seven.
