Year: 1841

page_text: TO ALL TO WHOM THESE PRESENTS SHALL COME, we, WIL-
LOUGHBY METHLEY and THOMAS CHARLES METHLEY, of Frith Street, Soho, in
the County of Middlesex, Ironmongers, send greeting.
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-sixth day of June, in the fifth year of Her reign,
did, for Herself, Her heirs and successors, give and grant unto us, the said
Willoughby Methley and Thomas Charles Methley, Her especial licence, full
power, sole privilege and authority, that we, the said Willoughby Methley
and Thomas Charles Methley, our exors, adñors, and assigns, or such others
as we, the said Willoughby Methley and Thomas Charles Methley, our exors,
adiiors, 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, the Invention of "IMPROVEMENTS IN
MACHINERY FOR RAISING, LOWERING, AND MOVING BODIES OR WEIGHTS,"
nicated to us by a certain Foreigner residing abroad; in which said Letters
Patent is contained a proviso that we, the said Willoughby Methley and
Thomas Charles Methley, or one of us, shall cause a particular description of
the nature of the said Invention, and in what manner the same is to be per-
formed, 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 proviso, we, the said
Willoughby Methley and Thomas Charles Methley, do hereby declare that the
nature of the said Invention, and the manner in which the same is to be
performed, are fully described and ascertained in and by the following state-

page_text: ment thereof, reference being had to the Drawings hereunto annexed, and to
the figures and letters marked thereon (that is to say):-
DESCRIPTION OF THE DRAWINGS.
Figure 1 represents a side view of machinery combined according to the
Invention, shewing the course a rope or cable takes around two barrels.
Figure 2 shews a similar side view, partly in section, the rope or cable being
omitted, by which the nature of the parts can be more readily traced.
Figure 3 is a plan of the machinery; and Figure 4 shews a plan of the
gearing.
In each of these Figures the same letters indicate similar parts, and the
machinery is arranged for working as a capstan.
a and b are two grooved barrels, the lower grooves, where the cable or rope
is first received, being rounding, and they gradually sharpen as, they come to
the upper parts of the barrel, as is shewn. c, c, are the axes or spindles,
which are fixed in a similar manner to the spindles or ordinary capstans. d,d,
is: a framing for receiving the upper ends e, e, of the axes or spindles c, c. At
the lower
part of each barrel is affixed a cog wheel f, and these cog wheels are
driven by means of the smaller cog wheel g, affixed on the axis or spindle h,
which turns in bearings i, i, carried by the framing d, and bed plate, as is
shewn; and on the upper end of the spindle h is affixed a capstan head j, to be
worked by ordinary' capstan bars'; and it will be evident that motion being.
communicated, to the spindle h by capstan bars, such motion will be commu-
nicated to the barrels a and b, and the power thereby obtained will be.
according to the size of the cog wheel 9 in respect to the wheels f, f. On
the under surface of one of the wheels f is affixed a ratchet wheel k, and 7, 1,
are palls taking into the ratchet wheel, whereby the ratchet wheel. prevents
the barrels a and b moving back. m is a cover for the gearing.. n is the
cable or rope coming into, the lower grooves of the barrels, and passing off from
the upper ones, as is shewn. 0, 0, are two guide pulleys to guide off the slack
of the rope or cable. And it will be found that by so using two barrels with
grooves the cable or rope will work without surging or fleeting..
We will now describe the second part of the Invention, which relates to a
mode of using two grooved barrels combined in their working, by which ropes.
or cables may be worked without surging or fleeting.
Figure 5 shews a plan of machinery combined according to this part of the.
Invention, suitable for the windlass of a ship. Figure 6 shews an end view,
and Figure 7 sliews a transverse section. a and b are two grooved barrels,
and a cable taking several turns around them; and it will be found that any
motion which may be communicated to one will be transmitted to the other by
i

page_text: the cable or rope which is being worked. The Drawing shews the machinery
suitably arranged for being worked by windlass bars; but other means may be
resorted to for working the windlass, particularly when additional power is re-
quired. All which is well understood in constructing windlasses, and forms no
part of the Invention. p is the pall wheel, and 9 the palls. ris a chain cable,
which will, in working of the barrels a and b, be found to lead freely into and pass
from the barrels without fleeting or surging; and the cable or rope will be con-
stantly drawn in, without stopping from time to time to clear, as heretoforo
necessary.
We would remark, that although we have only shewn the machinery
arranged in framing suitable for capstans and for windlasses, it will be evident
that the modes of combining two barrels may be used in cranes and other
arrangements of machinery where cables or ropes are used for raising, lower-
ing, or moving bodies and weights, and motion may be communicated thereto
by winch handles or by other means, as is well understood by mechanics.
Having thus described the nature of the Invention, and the manner of
performing the same, we would have it understood that we make no claim
to the parts separately, nor do we confine ourselves to the precise details, so
long as the peculiar modes of action be retained. But what we claim is,―
First, the mode of combining the action of two grooved barrels a and b, by
means of cog wheels f,f, and g, as above described.
And, secondly, we claim the mode of combining the action of two grooved
barrels a and b, as above described.
In witness whereof, I, the said Willoughby Methley, have hereunto
set my hand and seal, this Twenty-third day of December, in the year
of our Land One thousand eight hundred and forts ana
