CERTAIN IM- PROVEMENTS IN SHIPS' WINDLASSES, WHICH IMPROVEMENTS ARE ALSO APPLICABLE TO OTHER PURPOSES
Year: 1838

page_text: TO ALL TO WHOM THESE PRESENTS SHALL COME, I, THOMAS
MURRAY GLADSTONE, of Boottle-cum-Linacre, near Liverpool, in the County
Palatine of Lancaster, Chain Cable and Anchor Manufacturer, send grecting.
WHEREAS Her present most Excellent Majesty Queen Victoria, by Her
Letters Patent under the Great Seal of Great Britain, bearing date at
Westminster, the Twenty-first day of April, in the first year of Her reign,
did, for Herself, Her heirs and successors, give and grant unto me, the
said Thomas Murray Gladstone, Her especial licence, full power, sole privilege
and authority, that I, the said Thomas Murray Jackson, my exors, admors,
and assigns, or such others as I, the said Thomas Murray Gladstone, my
exors, admors, or assigns, should at any time agree with, and no others, from
time to time and at all times 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, and also in all Her said
Majesty's Colonies and Plantations abroad, my Invention of "CERTAIN IM-
PROVEMENTS IN SHIPS' WINDLASSES, WHICH IMPROVEMENTS ARE ALSO APPLICABLE TO
OTHER PURPOSES;" in which said Letters Patent is contained a proviso that
I, the said Thomas Murray Gladstone, shall cause a particular description of
the nature of my said Invention, and in what manner the same is to be
performed, to be enrolled 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.

page_text: NOW KNOW YE, that in compliance with the said proviso, I, the said
Thomas Murray Gladstone, do hereby declare that the nature of my said
Invented improvements, and the manner in which the same is to be per-
formed, are fully and particularly shewn in the Sheet of Drawings hereunto
annexed, and in the following description thereof, that is to say :-
Figure 1 of the said Drawing is an elevation of a ship's windlass as seen
when viewed from behind or looking forward with my said invented improve-
ments applied thereto, the starboard half of the windlass being shewn with
the casing on and the larboard with the casing off. Figure 2 is a ground
plan of Figure 1, and Figure 3 a side elevation of part of the windlass and
its accompaniments detached and laid open in order to shew more clearly the
mode in which the windlass works. The windlass is provided as usual with a
ratchet wheel and palls in the centre, but close to the side bits X, X,
or at any other convenient points. I fix upon the windlass spindle two
smaller supplementary ratchet wheels marked A, B, to which supple-
mentary ratchet wheels the motive force is applied in the manner herein-after
pointed out. The construction of the wheels A and B, which are precisely
alike, is shewn separately in Figures 4, 5, 6, 7 and 8. Figure 4 is a plan
of the inner side of the wheel; Figure 5, a side view of Figure 4; Figure 6,
à section of Figure 5; Figure 7, a side view of the outer side of the wheel;
and Figure 8, a section of Figure 7. The wheel, it will be observed, is mado
in its outer circumference of an octagonal form in order that it may fit upon
the body of the windlass, as shewn at C. D is a square hole, within which
the windlass spindle is wedged, and E a square piece in which the said square
hole is made, that fits into the opening F in the outer part of the wheels,
Figures 7 and 8. The means by which the ratchet wheel last described is
ȧcted upon are shewn as in combination in Figures 1 and 2, and more or less
detached in Figures 3, 9, 10, 11, and 12; G, of which Figure 9 is a separate
view, is a first lever, which revolves on the journal H of Figure 5. I is a
drag pall, attached to the lever G, and shewn sidewise in Figure 10, and the
plan in Figure 11. K is a push pall, also attached to the first lever. Figure 12
shows the first lever G complete, with its drag and push palls as applied to
the ratchet wheel. L, L, Figure 1, are two journals secured by bolts or
screws through the deck a, a; M, a shaft which passes through the eye holes
of the journals L, L, and rotates freely therein. N, N, two square sockets
for the reception of handspikes as shewn by O, O, Figures 1, 2, and 3. Pis
a crank attached to the end of the inner shaft M ; Q, a rod which connects
the cranks P with the first lever G, which acts immediately on the ratchet
wheel A or B. The handspike O when worked describes a quarter of a circle

page_text: as represented by the dotted lines in Figure 3. When at its highest point_
of elevation the system of levers of which it forms a part, present the form.
shewn in Figure 1 on the larboard side; when pulled a little way over, they.
take the position represented in Figure 3, and when the quarter revolution is:
completed, that exhibited on the starboard side of Figure 1; should it be
desired to increase the power of the leverage, that may be effected by unfore-
locking or unscrewing the connected rod Q; and attaching it to the crank P
at a point lower down than at first, for which purpose, there are holes made on
the crank P, as shewn at b, b, b, Figure 3. The two ratchet wheels A and B
may of course be either worked simultaneously by the means herein-before
described, or if a continuous rotation is desired, this may be effected by.
working them alternately. The number of handspikes applied may also be
increased from one on each side to three, four, or any other convenient
number, by making a corresponding addition to the, sockets with which tho
working shaft M is provided.
And having now described my said invented improvements, and the manner
in which the same are to be performed, I declare that I do not claim any of
the said wheels, palls, levers, or other mechanical contrivances as being in
themselves separately considered new, but that I claim as of my Invention.
the peculiar combination and allocation of mechanical means herein-before
described, by which the windlass is worked from the after part thereof; the
motive force is applied not directly to the windlass, but to a system of levers
of the first order, distinct from, yet connected therewith, and secured to the
deck in the manner shewn in the Drawings annexed, or in any other efficient
manner; a longer leverage is obtained by the common handspike, and with
more ease than usual. Any fleeting or shifting of the handspike after it is once
fixed in its socket is rendered unnecessary. Either an intermitting or continuous
rotation may be given to the windlass, and the upsetting of the windlass is
made impossible as long as the apparatus for working the same is kept fast in
its place. And I declare that the improvements herein-before described may
be applied to other purposes than to ships' windlasses, as, for instance, to the
raising of weights by means of a windlass in places and under circumstances
where a direct application of power to the windlass cannot be readily accom-
plished. And such my Invention being to the best of my knowledge and
belief entirely new and never before used within that part of Her said
Majesty's United Kingdom of Great Britain and Ireland called England,
1er said Dominion of Wales, or Town of Berwick-upon-Tweed, and also in
all Her said Majesty's Colonies and Plantations abroad, I do hereby declare
this to be my Specification of the same, and that I do verily believe that this

page_text: my said Specification doth comply in all respects fully and without reserve or
disguise with the proviso in the said herein-before in part recited Letters
Patent contained; wherefore I do hereby claim to maintain exclusive right
and privilege to my said Invention.
In witness whereof, I, the said Thomas Murray Gladstone, have hereunto 5
set my hand and seal, this Sixteenth day of October, One thousand
eight hundred and thirty-eight.
THOMAS MURRAY (L.s.) GLADSTONE.
AND BE IT REMEMBERED, that on the Sixteenth day of October,
in the year of our Lord 1888, the aforesaid Thomas Murray Gladstone
came before our said Lady the Queen in Her Chancery, and acknowledged
the Specification aforesaid, and all and every thing therein contained and "
specified, in form above written. And also the Specification aforesaid was
stamped according to the tenor of the Statute made for that purpose.
Enrolled the Twentieth day of October, in the year of our Lord One 1
thousand eight hundred and thirty-eight.
