CERTAIN IMPROVEMENTS IN MANGLES
Year: 1831

page_text: TO ALL TO WHOM THESE PRESENTS SHALL COME, we, JOHN LEE
STEVENS, Auctioneer, and PETER WAYCOTT, Clock and Watchmaker, both of
Plymouth, in the County of Devon, send greeting.
WHEREAS His present most Excellent Majesty King William the Fourth,
by His Letters Patent under the Great Seal of Great Britain, bearing dato
at Westminster, the Twenty-second day of June, in the first year of His reign,
did, for Himself, His heirs and successors, give and grant unto us, the said
John Lee Stevens and Peter Waycott, His especial licence, sole privilege
and authority, that we, the said John Lee Stevens and Peter Waycott, our
exécutors, administrators, and assigns, or such others as we, the said John
Lee Stevens and Peter Waycott, our executors, administrators, 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 mentioned, should and lawfully might
make, use, exercise, and vend, within England, Wales, and the Town of
Berwick-upon-Tweed, and also in all His said Majesty's Colonies and
Plantations abroad, our Invention of "CERTAIN IMPROVEMENTS IN MANGLES;"
in which said Letters Patent is contained a proviso that we, the said John Lee
Stevens and Peter Waycott, under our hands and seals, or under the hand
and seal of one of us, shall cause a particular description of the nature of our
said Invention, and in what manner the same is to be performed, to be
inrolled in His 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: HOW KNOW YE, that in compliance with the said proviso, I, the said
Peter Waycott, for myself and the said John Lee Stevens, do hereby declare
that the nature of our said Invention, and in what manner the same is to be
performed, are particularly described and ascertained by the following
description thereof, reference being had to the Drawing hereunto annexed,
and to the figures and letters marked thereon, that is to say :-
Our improvements in the construction of mangles consists in two new
modes of lifting the mangle box to release the rollers from the pressure when
it is wished to take them out of the mangle.
Figure 1 of the accompanying Drawings is a front view of a mangle with
our improvement adapted to it; Figure 2 is a top or bird's-eye view; and
Figure 3 is an end view of the same, the letters of reference marked thereon
referring to similar parts in all the Figures. a, a, a, a, is the framework and
standards of the mangle; b, b, the bed; c, c, the box or weighted trunk
pressing upon the rollers d, d; e is the winch handle, by which the operator
gives motion to the box. Upon the axis f of this handle is mounted the
spur wheel or pinion g and fly wheel . The pinion g takes into and com-
municates motion to a toothed wheel i, which turns loosely on a short axis fixed
in the standard a. j is a shaft or axis, having one end forked, the prongs fitting
loosely into holes in the wheel i. On the reverse end of this axis j is fixed
the pinion k, taking into the rack 1, 7. This rack is formed on a bar of iron
or other metal m, m, extending from end to end of the mangle. Supposing
the pinion to be in gear with the upper side of the rack, as shewn in the
Drawings, it will cause the rack 7, and with it the box c, c, to be drawn one
way through the frame, the rack and box being kept united by the pins n,'n,
on the ends of the bar m, m, projecting outside of the guides o, o. On the
pinion arriving at either extremity of the rack it will be allowed to turn
round the end, and be kept in gear with the under side of the rack by the
guides p, p. The motion of the winch continuing, the box and rack will be
driven the reverse way through the frame until the pinion reaches the other
extremity, when it will be guided round the end and into gear with the upper
side by the guide piece 2, and so on. The rack is kept in its proper place by
passing under the guide pieces q fixed on the back piece r (see the detached
Figure 4), and over the friction roller s, turning on axis also fixed in the
piece 7.
All the foregoing parts are constructed as in mangles now in common
use. When the operation of mangling is performed, it is necessary to
relieve the rollers from the pressure of the box before they can be removed.
We construct our improved mangles to do this in two ways:--

page_text: First, by connecting the end of the mangle box to be raised by a pin and
chain to the shaft or axis f of the winch handle, and as the shaft revolves it
coils up the chain round it, and raises the box.
Second, by making the bar m, m, to act as a lever (like the beam of a steel
yard) to raise the end of the box, the friction roller u being the fulcrum.
In the first of these modes of raising the end of the box the pin t in the
upright standard p must be removed from under the bar m at the end
intended to be raised, and as soon as the extremity of the rack / arrives near
to the pinion k the pin on the end of the short chain u fastened to the lid of
the box is to be placed through the hole v on the shaft f, which, as it continues
to revolve, will coil the chain round it, and raise the end of the mangle box, see
the detached sectional view, Fig. 5, the slots between the standard guides o, o,
allowing it to approach nearer to the bar m. The click or pall w is then to
be brought into contact with the teeth of the spur wheel g, by which the end
of the box will be kept suspended, the pall preventing the shaft from turning
the reverse way to uncoil the chain. The roller can now be removed and a
fresh one substituted, and on removing the pall w from out of the teeth of the
wheel g the handle will be allowed to turn the reverse way, and the pin on the
end of the chain will fall out of the hole v in the shaft f. The same opera-
tion is to be performed to raise the other end of the box when the mangling
may be continued.
In the second mode, when the box is within the frame (that is, when the
ends of the rack are about equidistant from the pinion,) the pin t is to be taken
out of the hole in the upright guides o, o, when that end of the bar m may be
depressed or allowed to descend, which it will do by its own gravity, as the
pinion k approaches the other extremity of the rack. The pin t is then to be
placed into the hole in the upright standard o, above the bar m, when, after
the pinion has turned round the extremity of the rack, and is again proceeding
towards the end to be raised, the weight of the reverse extremity of the bar
and rack will act as a lever, the friction roller u being the fulcrum, and by its
gravity raise the end of the box, as shewn in the detached Figure 5, taking
the weight from off the roller, which can be removed and another one
substituted. As the winch handle continues to be turned the end of the box
will fall down again upon the roller, when the mangling may proceed, and
after passing the centre the ends of the bar m will preponderate and fall away
from under the pin t, which is now to be removed from out of the hole x, and
after the pinion k has turned round the extremity of the rack, and again
approached near to the end, which has now been raised, the pin t is to be
placed into its former position under the bar. After this operation has been

page_text: performed at the roverso end of the mangle, the mangling may proceed without
interruption.
In this our foregoing Specification I have necessarily described many parts
which are not new, and which we do not claim as our Invention; but we wish
it to be understood, that what we do claim as our Invention is, the two modes
which I have described of lifting the end of the mangle box to allow of the
rollers being removed, and which we believe to be entirely new, and never
before used within that part of His said Majesty's United Kingdom of Great
Britain and Ireland called England, His Dominion of Wales, and the Town of
Berwick-upon-Tweed.
In witness whereof, I, the said Peter Waycott, havo hereunto set my
hand and seal, this Twenty-second day of August, in the year of our
Lord One thousand eight hundred and thirty-one.
PETER (L.B.) WAYCOTT.
AND BE IT REMEMBERED, that on the Twenty-second day of August,
in the second year of the reign of His Majesty King William the Fourth, the
said Peter Waycott came before our said Lord the King in His Chancery,
and acknowledged the Instrument aforesaid, and all and every thing therein
contained and specified, in form above written. And also the Instrument
aforesaid was stamped according to the tenor of the Statute made in the
fifty-fifth year of the reign of His late Majesty King George the Third.
Inrolled the Twenty-seventh day of August, One thousand eight hundred
and thirty-one.
