AN IMPROVED MANGLE
Year: 1841

page_text: TO ALL TO WHOM THESE PRESENTS SHALL COME, I, CHARLES
BARNARD, of the City of Norwich, Ironmonger, 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 Thirteenth day of January, One thousand eight hundred
and thirty-eight, in the first year of Her reign, did, for Herself, Her heirs
and successors, give and grant unto me, the said Charles Barnard, Her
especial licence, full power, sole privilege and authority, that I, the said
Charles Barnard, my exors, adiñors, and assigns, or such others as I, the said
Charles Barnard, my exors, admňors, 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, my Invention
of "AN IMPROVED MANGLE;" in which said Letters Patent is contained a proviso
that I, the said Charles Barnard, shall cause a particular description of
the nature of my said Invention, and in what manner the same is to be
performed, to be inrolled in Her said Majesty's High Court of Chancery
within two 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
Charles Barnard, do hereby declare that the following is a particular description
of the nature of my said Invention, and of the manner in which the same is
to be performed, reference being had to the Drawings hereunto annexed, that
marked No. 1 being a side elevation of my said improved mangle, and that
marked No. 2 an end elevation thereof, the same letters of reference denoting
similar parts in both Sheets of Drawings, that is to say:―
N, N, N, is the framework of the machine. A, B, and C, are three
rollers or cylinders. E is a cross rail at the bottom of machine, from which
is suspended the weight F. K, K, are vertical grooves or slots in the upright
posts of the framework N, in which the ends of the axis of the roller A are
free to move up and down. M, M, are two other vertical grooves or slots in
the said upright posts, in which the ends of the cross rail E are also free to
move up and down. D, D, are bars inserted in grooves in the inner side of
the upright posts (N, N, as shewn by the dotted lines in Drawing No. 2), for
the purpose of connecting the roller -A with the cross rail E, and the weight F
attached thereto. The form of one of these bars is shewn more clearly at
Figure 3 in Drawing No. 1, d being the hole through which the axis of the
roller or cylinder A passes. X, X, a slot to allow of the free action of the
axes of the rollers or cylinders B and C, and the hole for receiving the end
of the cross rail E. L, L, are grooves or slots in the uprights posts of the
framework, in which the ends of the axis of the middle roller B are free to
move, but which grooves or slots form a segment of a circle instead of being
vertical. The vertical slot K and the curved slot L are more clearly shewn
in Figure 4, Drawing No. 1, which exhibits a portion of one of the posts N
with the slots therein, the wheel G being removed. G is a wheel fixed to one
end of the axis of the wheel B (outside of the framework N, N, N,) and
H, & pinion which works into the teeth of the wheel G, the slots or grooves
L, L, being segments of circles described from the centre of the said pinion H.
C, which is the lowest of the three rollers, is required to revolve at one fixed
point of elevation only, and has, therefore, no such range of action provided
for as in the case of the rullers A and B. O is the table which carries the
articles to be mangled or calendered; I', brackets supporting the table O, and
projected from the framework N.
Figure 5 is a section of the middle roller B, shewing the manner in which
the mangle cloth Z is attached to the said roller B. A groove R is made
along the whole length of the roller B, into which a rod P of brass, or other
material, is made to fit exactly. The end of the mangle cloth is sewn so as to
form a loop or hem, and the rod P being passed through such loop or hem, it

page_text: is placed in the groove R, R, the one end of the rod being secured in a hole
or socket at one end of the roller B, and the other end of the rod with a screw
at the other end of the roller. By this means the mangle cloth is made to
start true, and the trouble of adjusting the same avoided.
Before setting the machine to work, the linen or other cloth Z is attached
to the middle roller B, in the manner before mentioned, and brought over the
table O, and on the cloth the articles to be mangled or calendered are laid. A
winch I being now applied to the axis of the pinion H, and being turned, the
roller B is made to revolve, the linen or other cloth Z to wind itself together
with the articles to be mangled or calendered placed thereon upon the roller B,
and the roller B, in consequence of the circular range of action given to it by
the curved grooves or slots L, L, to rise in these grooves or slots in proportion
as its diameter is increased by the plies or laminations of the articles to be
calendered or mangled, and of the linen or other cloth Z, while, by the
counteraction of the rollers A and B, and the weight F, the articles which
have been placed on the table. O and wound round the roller or cylinder B, are
mangled or calendered to any degree ordinarily required.
And having now described the nature of my said Invention, and the manner
in which the same is to be performed, I declare that the framework rollers
and other parts of the said machine before described may be either of wood
or of iron, or partly of wood and partly of iron, or of any other suitable
materials. And I declare also that I do not claim any of the parts of the
said machine as in themselves new and of my Invention.
But that what I claim as new and of my Invention is, the particular
arrangement and combination of mechanical means herein-before described
and exemplified in the Drawings hereunto annexed, which constitutes in its
entirety the improved mangle, for which I have obtained the Letters Patent
aforesaid; 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, Her
said Dominion of Wales, or Town of Berwick-upon-Tweed, I do hereby
declare this to be my Specification of the same, and that I do verily believe
this 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 Charles Barnard, have hereunto set my
hand and seal, this Sixteenth day of February, One thousand eight
hundred and thirty-eight.
CHARLES (L.S.) BARNARD.
