Year: 1817

page_text: TO ALL TO WHOM THESE PRESENTS SHALL COME, we, WILLIAM
GELDART and JOHN SERVANT, both of Leeds, in the County of York, House
Carpenters and Co-partners, send greeting.
WHEREAS His most Excellent Majesty King George the Third did, by His
Letters Patent under the Great Seal of the United Kingdom of Great Britain
and Ireland, bearing date at Westminster, the Twelfth day of August, in the
fifty-seventh year of His reign, give and grant unto us, the said William
Geldart and John Servant, our exors, adñiors, and assigns, His special licenco,
full power, sole privilege and authority, that we, the said William Geldart and
John Servant, our exors, admors, and assigns, should and lawfully might,
during the term of years therein mentioned, make, use, exercise, and vend,
within England, Wales, and the Town of Berwick-upon-Tweed, our Inven-
tion of "CERTAIN IMPROVEMENTS ON MANGLES;" in which said Letters Patent
there is contained a proviso that if we, the said William Geldart and John
Servant, or one of us, should not particularly describe and ascertain the nature
of our said Invention, and in what manner the same is to be performed,
by an instrument in writing under our hands and seals, or under the hand
and seal of one of us, and cause the same to be inrolled in our High Court
of Chancery within two calendar months next and immediately after the
date of the said Letters Patent, that then the said Letters Patent, and all
liberties and advantages whatsoever thereby granted, shall utterly cease,
determine, and become void, as in and by the same, relation being thereunto
had, may more fully and at large appear.

page_text: NOW KNOW YE, that in compliance with the said proviso, we, the said
William Geldart and John Servant, do hereby declare that the nature of our
said Invention, and the manner in which the same is to be performed, are
particularly described and ascertained in and by the following description
thereof, and the Drawings hereunto annexed, that is to say :-
A is a wood frame three feet and two inches long, two feet and two inches
in width the whole extent of its greatest extremity, one foot and three inches
and a half in width at the top, four feet and six inches in height at the back,
three feet in height in front from a to a, both ends of which frame are of the
same dimensions. A, a, is part of the said frame, and is one foot and seven
inches in length, one inch and an half thick, and five inches and a half in
width, in which is fixed metal bushes for the roller D and the metal plates
herein-after mentioned. B is a diagonal brace at each end of the said frame,
two feet long, to which the spring G is fixed. C is a metal plate five inches
and a half square, and half an inch thick, fixed into each end of the frame
upon the standard A, a, in the centre of which is an aperture for the axle
of the pressure roller D, and which will admit of the roller rising or falling.
D is a wood roller two feet and seven inches in length, and seven inches in
diameter, fixed in the frame with an iron axle and metal bushes, upon which
roller a cloth is fixed to receive the linen. E is a pressure roller of the same
dimensions as D. F is a tumbling shaft which runs in metal bushes fixed in
the said frame, on the one end of which is fixed the cog wheel M and on the
other the balance wheel N. G is a lever at each end of the frame fixed
at A, a, resting on the axles at each end of the roller E. H is a spring, one
end of which is fixed by an iron screw and clasp to the diagonal brace B.at b.
I is a spear which unites the power of the lever G and the spring H, and
presses the roller E upon the roller D. K is a finger screw at the head of the
spear I, by which the spring is tightened or slackened at pleasure so as to
produce a greater or less degree of pressure. L is a pinion. wheel twelve
inches in diameter, fastened by a screw on the axle at one end of the roller D.
M is a cog wheel, two inches and a half in diameter, fixed on one end of the
tumbling shaft F. N is a balance wheel fixed at the other end of the
tumbling shaft F. O is an elbow crank or handle which turns the cog wheel
M. P is a drawer fixed in the frame A, which draws out to support-the
table Q. Qis a table for spreading the linen on, a part of which rests upon
and is fixed to the frame A, and the other part of which, when necessary, rests
upon the drawer P, and which last-mentioned part of the said table is attached
to the other parts thereof by hinges, and shuts up when the mangle is not in
R is a linen cloth three yards in length and three-quarters of a yard in
use.

linen.
The improvements to which we claim an exclusive title under our said
Letters Patent are in the spear I and the screw K, and the manner of
applying the same to the spring H and the lever G, so as not only to give
power to the lever G and press the roller E upon the roller D, but also, by
using the screw K, increasing or diminishing such power or pressure as
occasion may require.
Our said improvements are not confined to any particular kinds of mangles
alone, but the same are applicable where larger rollers or cylinders are used,
as we are confined to neither size or material.
Directions for using mangles used by us:-Pull out the drawer and lay the
tables; take hold of the cloth and draw it off the roller by turning the handle
backwards, then lay on your linen, begining close to the roller, taking care
to lay it as regular in thickness as possible until the cloth is filled; after
turning the handles a few times take hold of the end of the cloth and turn the
handle the contrary way, and your linen will come out perfectly mangled.
When the screws at the end of the spears are slack upon the lever, so as to
leave the spring at rest, the mangle is then properly weighted for common
mangling, and the screws must not be screwed tight unless for silks or thin
goods, but should a greater degree of power or pressure be wanted, then the
screw must be tightened.
In witness whereof, we, the said William Geldert and John Servant, have
hereunto set our hands and seals, this Twenty-fourth day of September,
in the year of our Lord One thousand eight hundred and seventeen.
