AN IMPROVED MANGLE
Year: 1853

page_text: LETTERS PATENT to John Hall, of Bedford, Machinist, for the
Invention of "AN IMPROVED MANGLE."
PROVISIONAL SPECIFICATION left by the said John Hall at
the Office of the Commissioners of Patents, with his Petition,
on the 23rd July 1858.
I, JOHN. HALL,.do hereby declare the nature of the said Invention for
"AN IMPROVED MANGLE" to be as follows:-.
This Invention relates to a novel construction of mangle wherein the
driving of the roller on which the goods under operation are lapped is.
not made to depend upon friction of contact, but motion is communi-
cated thereto by means of geering wheels so constructed as to admit of
the top roller rising with its bearings (as it increases in diameter by the
continuation of the winding on motion).without the wheels being thrown
out of geer. These pressing rollers are arranged one above the other.
The two lower rollers' are geered together by ordinary.cog-wheels,

page_text: but rotary motion is communicated from the middle to the top roller,
which is weighted by star wheels, the arms of which work together like
the teeth of cog-wheels. The conducting blanket is attached to the
top roller, and brought down between the bite of that and the middle
roller, and thence between the bite of the middle and lower roller to
the table in front of the machine. In operating this machine the
articles to be mangled are laid out flat on the blanket, and the rollers
are set in motion by a winch handle or other contrivance until the
articles have been drawn into the machine, and wound with the blanket
upon the top roller; the direction of motion is then reversed, and the
blanket is brought back to the table. The machinery is enclosed in a
case somewhat resembling a bureau; it will therefore present no un-
sightly appearance, and will be protected from dust and dirt.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said John Hall in the Great Seal Patent Office, on
the 23rd January 1854.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I,
JOHN HALL, of Bedford, Machinist, send greeting.
WHEREAS Her most Excellent Majesty Queen Victorin, by Her
Letters Patent, bearing date the Twenty-third day of July, in the year
of our Lord One thousand eight hundred and fifty-three, in the seven-
teenth year of Her reign, did, for Herself, Her heirs and successors,
give and grant unto me, the said John Hall, Fler special license that
I, the said John Hall, my executors, administrators, and assigns, or
such others as I, the said John Hall, my executors, administrators, and
assigns, should at any time agree with, and no others, from time to
time and at all times thereafter during the term therein expressed,
should and lawfully might make, use, exercise, and vend, within the
United Kingdom of Great Britain and Ireland, the Channel Islands,
and Isle of Man, an Invention for "AN IMPROVED MANGLE," upon the
condition (amongst others) that I, the said John Hall, by an instru-
ment in writing under my hand and seal, should particularly describe
and ascertain the nature of the said Invention, and in what manner

page_text: the same was to be performed, and cause the same to be filed in the
Great Seal Patent Office within six calendar months next and imme-
diately after the date of the said Letters Patent.
NOW KNOW YE, that I, the said John Hall, do hereby declare
the nature of my said Invention, and in what manner the same is to be
performed, to be particularly described and ascertained in and by the
following statement, reference being had to the Drawing hereunto
annexed, and to the letters and figures marked thereon (that is to
say):
.
This Invention relates to a novel construction of mangle wherein
the driving of the roller on which the goods under operation are lapped
is not made to depend upon friction of contact, but motion is commu-
nicated thereto by means of gearing wheels so constructed and arranged
as to admit of the top roller, with its bearings, moving up and down
vertically as the lapping on roller increases in diameter by the lapping
or winding thereon of the goods or fabrics under operation. The
several parts are so constructed and arranged that this operation can
be effected without the gearing wheels being thrown out of gear. The
rollers are arranged one above the other, and the top pressing roller is
the one to which the weight or pressure is directly applied. Motion is
communicated thereto from the lower roller by a pair of star wheels,"
one of which is mounted on the axle of the top roller, and the other on
a fixed stud attached to the framing, so that the arms of these wheels
may work together like the teeth of cog-wheels.
The conducting
blanket is attached to the middle roller, and passes under the bite of
that and the top roller, and thence under the bite of the middle and
lower roller to the table in front of the machine. In operating this
machine the articles to be mangled are laid out flat on the blanket,
and the rollers are set in motion by a winch handle or other contrivance,
until the articles have been drawn into the machine, and wound with
the blanket upon the middle roller; the direction of motion is then
reversed, and the blanket is brought back to the table. The machinery
is enclosed in a case somewhat resembling a bureau; it will therefore
present no unsightly appearance, and will be protected from dust and
dirt.

page_text: In order, however, that my Invention may be more clearly under-
stood I have shewn various views in the accompanying Drawing, in
which Fig. 1, is an end elevation of the machine, shewing the arrange-
ment of gearing for driving the various parts. Fig. 2, is a front elevation
of the same; and Fig. 3, is a transverse vertical section. a, a, is the
box, case, or framework for supporting the various parts. b, b, is a cast
iron or other strong framing for receiving the bearings of the pressing
rollers c, d, e. The framing b,, is screwed, bolted, or otherwise fixed.on
the lower case or framing a, and also carries the bearings of the main
driving shaft f, one end of which carries the fly wheel g; and the other
ent is provided with a winch handle h, for communicating motion thereto.
The lower pressing roller is actuated by means of the toothed gearing
i, i, i, (Fig 1, and 2,) and rotary motion is transmitted from the lower
roller c, by means of the toothed wheel i, to a similar wheel j, mounted
loosely on a stud. projecting from the framing b: Connected to this
wheel j, is a star wheel k, which gears into a similar wheel 1, on the
axle of the top pressing rollere; which is capable of moving vertically
in slotted guides made in the iron framing b. It will now be seen that
as the diameter of the roller d, increases, by reason of the goods or
fabrics under operation being lapped or wound thereon, the distance
between the rollers c, d, and e, must necessarily increase, and conse-
quently, if ordinary toothed wheels were used for communicating motion
to the top roller they would soon be lifted out of gear. By the employ-
ment of the star wheels k, and I, this is prevented, as the length of the
arms of these wheels admits, of the upper roller being lifted up a
considerable distance without the wheels being taken out of gear.
The upper pressing roller e, is weighted by the box m, m, which is
filled or partly filled with stone or any weighty material, and is sus-
pended from the axle of the roller e, by the links n, n, (Fig 2,
and 3.) The front board a*, (Fig. 1,) of the outer case is hinged at
its upper part to the fixed wooden framework, so that it may, when
lifted up and brought into a horizontal position, as shewn in. Fig. 3,
form a board or table to receive the goods or fabrics. The inclined
front board a³, is also hinged, so that when the machine is in use it
may be thrown back, as shewn in Fig. 8.

page_text: Having now described my Invention, and the best means with which
I am at present acquainted for carrying the same into effect, I would
observe, in conclusion, that I do not mean or intend to confine myself
rigidly to the precise arrangement or construction of parts herein shewn
and described, as they may, perhaps, be varied without departing from
the nature and object of my Invention, nor do I claim the exclusive
right to apply weighted rollers to mangles; but that which I consider to
be new, and therefore desire to claim as the Invention secured to me e by
Letters Patent as aforesaid, is,-
First, the general arrangement and construction of parts herein
shewn and described.
And, second, I claim actuating the top pressing roller by means of
star wheels or other equivalent contrivance, which will always remain
in gear,
and yet admit of the upper rollers rising as the goods or fabrics
become lapped round the middle roller.
In witness whereof, I, the said John Hall, have hereunto set my
hand and seal, this Twenty-first day of January, in the year
of our Lord One thousand eight hundred and fifty-four.
