IMPROVEMENTS IN MANGLES
Year: 1827

page_text: TO ALL TO WHOM THESE PRESENTS SHALL COME, 1, SAMUEL
WILKINSON, of Holbeck, in the County of York, Mechanic, send greeting.
WHEREAS His most Excellent Majesty King George the Fourth did,
by His Letters Patent under the Great Seal of the United Kingdom of Great
Britain and Ireland, bearing date at Westminster, the Fourth day of Decem-
ber, in the eighth year of His reign, give and grant unto me, the said Samuel
Wilkinson, my exors, admors, and assigns, His special licence, full power,
sole privilege and authority, that I, the said Samuel Wilkinson, my exors,
adiiors, and assigns, should and lawfully might, during the term mentioned,
make, use, exercise, and vend, within England, Wales, and Town of
Berwick-upon-Tweed, my Invention of "IMPROVEMENTS IN MANGLES," which
I intend to denominate Bullman's patent cabinet mangle; in which said
Letters Patent there is contained a proviso, that if I, the said Samuel Wilkinson,
shall not particularly describe and ascertain the nature of my said Invention,
and in what manner the same is to be performed, by an instrument in writing.
under my hand and seal, and cause the same to be enrolled in His Majesty's
High Court of Chancery within six calendar months next and immediately
after the date of 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, reference being thereunto had, may, more fully and at
large appear.
NOW KNOW YE, that, in compliance with the said proviso, I, the said
Samuel Wilkinson, do hereby declare that the nature of my said Invention,

page_text: and the manner in which the same is to be performed, are particularly
described and ascertained in the Drawings or -Diagrams hereunto annexed,
and the following description thereof (that is to say) :-
Certain improvements in the machine called a mangle (which I purpose
denominating Bullman's improved cabinet mangle for smoothening clothes,
&c., so as to occupy the smallest space, at the same time embracing all the
requisite advantages, and applicable alike to all the purposes where linen or
other substances require to be smoothened. A, B, C, D, Figure 1, a strong
three-inch square framing, firmly bolted together; three feet one inch long,
two feet three inches wide, two fect cleven high at front, and four feet six
inches high at back; E, a side rail, six inches by one and a half, into which
is framed the upright F, of the same strength which supports the rollers G, H,
Figure 3, each of which are seven inches diameter. The pressure is given
by two iron flat weights I, of eighteen pounds each, attached to the levers K,
moving on the pin at L, and working in the slot M, while the extremity
describes the dotted line N; O, a rod connecting the levers P and K; Q,
Figure 4, a strong bolt and nut (this Diagram, Figure 4, is given double the
size the better to show its parts), on which the upper lever P works, and is
fixed to a strong iron plate firmly screwed to the upright F; R, a hardened
steel plate, dovetailed into the lever working upon the case-hardened shaft ends
S, S, of upper roller G; T, the winch or handle attached to a shaft and small
fly-wheel U (to accelerate and regulate the motion) carrying the pinion weel W
working in the cog-weel X, and turning the lower roller H, which contains
the mangling cloth v, and on which the linen &c., is laid when the machine is
in use. Figure 5, an iron cross bar, connecting the two upper lines P, P'; a
lifting force applied to the centre of which at Y (by means of the crank weel,
chain, and lever z, a, Figure 6) removes the pressure from the upper roller
and rises it, admitting the linen, &c. being withdrawn without creasing it. The
pressure can likewise be taken off by means of an iron crank and lever at
Figure 7. I do not attach any claim of novelty to the outward form of the
machine, or to the rollers, or to the mode of working the same; but I do claim
an exclusive right of Invention to the mode and means by which the pressure
is given to the machine, and to the method by which the pressure is taken off,
which are the two principle points required, and have heretofore been a great
desideratum in all machines where fixed rollers have been used. The parts
which I claim as new applicable to this machine are in the Diagrams colored red.
My mode of giving the pressure will not subject the machine to the variation
which powerful springs have always done; there will be always precisely the
same pressure upon the upper roller, if nearly empty, as when the 'mangle is

page_text: quite fill'd, and this advantage can always be preserved by a contrivance which
I have made in the connecting rod for the adjusting the pressure when the
metals may, from length of time, wear down; a'swivel joint at the upper end
at a, Figure 4, and a screw joint at e on the lower end leaves the rod at liberty
to be lengthened or shortened by means of a small square on the rod at 6,
when the lower point of the lever weight I will always be a sure guide to
know when the weight is working free, if kept near the lower edge of the
rail at C. The advantage in using the chain and crank weel, in taking off the
pressure, in preference to the common crank, is, that by leaving a fullness in
the chain, it will admit the parts wearing away without affecting the action
of the lever. With the common crank, when the parts wear away, the cross
bar will rest upon the crank and prevent its free action. The arrangement of
the machinery will in no way prevent the space in the centre being converted
into and fitted up as a large closet or a chest of drawers, as occasion may
require, for either of which purposes it will be equally applicable.
In witness whereof, I, the said Samuel Wilkinson, have hereunto set
my hand and seal, this Eighth day of January, One thousand eight
hundred and twenty-eight.
SAMUEL (L.s.) WILKINSON.
Signed, sealed, and delivered, by the
within-named Samuel Wilkinson, in
