IMPROVEMENTS IN MANGLES
Year: 1868

page_text: LETTERS PATENT to George Warsop, of No. 73, Mount Street,
Nottingham, for the Invention of "IMPROVEMENTS IN MANGLES."
PROVISIONAL SPECIFICATION left by the said George Warsop at
the Office of the Commissioners of Patents, with his Petition, on the
7th January 1868.
I, GEORGE WARSOP, of No. 73, Mount Street, Nottingham, do hereby
declare the nature of the said Invention for "IMPROVEMENTS IN MANGLES,"
to be as follows:-
This Invention has for its object improvements in mangles. For this
purpose I employ a roller supported in bearings at one end of a frame;
around the roller is a sheet of canvas or other material which can be
wound around or unwound from it. To the opposite end of the frame is
fixed one end of a spring board, which board extends from end to end of
the frame and passes below and can be caused to press against the under
side of the roller above mentioned; the end of the spring board also
carries a roller which presses against the side of the roller around which
the canvas is wound. When the canyas is unwound from the roller it

page_text: lies along the top of the spring board, and whilst the canvas is thus
extended over the board the clothes or other articles are spread out upon
it; the roller is then turned to wind up the canvas, the spring board
being at the same time caused to press up towards the roller. The
board is caused to press up towards the roller by short arms or eccentrics
on an axis which passes from side to side of the frame below the board;
this axis has attached to one of its ends a long lever arm by which it
can either be turned in a direction to cause the short arms or eccentrics
to press against the under side of the board, or in a direction to move
these arms or eccentrics away from it when it is desired that the board
shall no longer press against the roller, around which the sheet of
canvas is wound; the lever arm can be retained in either one or other
position by being sprung into notches. The roller around which the
canvas is wound has a toothed wheel upon it, which wheel is by an
intermediate wheel geared with a pinion which can be turned by a hand
or fly wheel; this pinion can be made either fast or loose with the fly
wheel by means of a sliding clutch which is pressed into gear by a spring
lever, but which is drawn out of gear during the time the spring board is
not pressing against the roller. This is effected by causing the long lever
arm on the axis below the spring board to act upon the spring lever
of the clutch in such a manner as to draw the clutch out of gear
whenever the lever arm is turned into a position to release the spring
board from pressure. By this arrangement when the spring board is not
in action the sheet of canvas can by merely pulling on its end be
readily unwound from the roller, as the roller will then turn freely, it
being at this time disconnected from the hand or fly wheel which turns
it. The sheet of canvas when thus unwound will also remain drawn out
tightly, so as to lie flat upon the spring board, as the canvas roller will
not continue to turn after the desired length of canvas has been drawn
off from it.

Letters Patent, bearing date the Seventh day of January, in the year of
our Lord One thousand eight hundred and sixty-eight, in the thirty-first
year of Her reign, did, for Herself, Her heirs and successors, give and
grant unto me, the said George Warsop, Her special licence, that I, the
said George Warsop, my executors, administrators, and assigns, or such
others as I, the said George Warsop, 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 "IMPROVEMENTS IN MANGLES," upon the con-
dition (amongst others) that I, the said George Warsop, my executors or
administrators, by an instrument in writing under my, or their, or one
of their hands and seals, should particularly describe and ascertain the
nature of the said Invention, and in what manner 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 immediately after the date of the
said Letters Patent.
NOW KNOW YE, that I, the said George Warsop, do hereby declare
the nature of the said Invention, and in what manner the same is to
be performed, to be particularly described and ascertained in and by the
following statement thereof, that is to say :-
This Invention has for its object improvements in mangles. For this
purpose I employ a roller supported in bearings at one end of a frame;
around the roller is a sheet of canvas or other material which can be
wound around or unwound from it. To the opposite end of the frame is
fixed one end of a spring board, which board extends from end to end of
the frame and passes below and can be caused to press against the under
side of the roller above mentioned; the end of the spring board also
carries a roller which presses against the side of the roller around which
the canvas is wound. When the canvas is unwound from the roller it
lies along the top of the spring board, and whilst the canvas is thus
extended over the board the clothes or other articles are spread out upon
it; the roller is then turned to wind up the canvas, the spring board
being at the same time caused to press up towards the roller. The
board is caused to press up towards the roller by short arms or eccentrica

page_text: on an axis, which passes from side to side of the frame below the board;
this axis has attached to one of its ends a long lever arm by which it can
either be turned in a direction to cause the short arms or eccentrics to
press against the under side of the board, or in a direction to move these
arms or eccentrics away from it when it is desired that the board shall
no longer press against the roller around which the sheet of canvas is
wound; the lever arm can be retained in either one or other position
by being sprung into notches. The roller around which the canvas is
wound has a toothed wheel upon it, which wheel is by an intermediate
wheel geared with a pinion which can be turned by a hand or fly wheel;
this pinion can be made either fast or loose with the fly wheel by means
of a sliding clutch which is pressed into gear by a spring lever, but
which is drawn out of gear during the time the spring board is not
pressing against the roller. This is effected by causing the long lever arm
on the axis below the spring board to act upon the spring lever of the
clutch in such a manner as to draw the clutch out of gear whenever
the lever arm is turned into a position to release the spring board from
pressure. By this arrangement when the spring board is not in action
the sheet of canvas can by merely pulling on its end be readily unwound
from the roller as the roller will then turn freely, it being at this time
disconnected from the hand or fly wheel which turns it. The sheet of
canvas when thus unwound will also remain drawn out tightly so as to
lie flat upon the spring board as the canvas roller will not continue to
turn after the desired length of canvas has been drawn off from it.
And in order that my Invention may be fully understood and readily
carried into effect, I will proceed to describe the Drawings hereunto
Figure 1 shews a side view and Figure 2 an end view of a mangle
constructed as above described.
a is the framing of the machine formed at one of its ends with
bearings to receive the axis of the roller b against which the smaller
roller c is caused to press; this roller is carried at the end of a board d,
which passes below the roller b, and is at its opposite end fixed to the
framing a. To the roller 6 is fixed the end of a sheet of canvas e, which
is of the same width or nearly so as the board d; this sheet of canvas, and

page_text: the rollers b and c, and the board d are shown separately in longitudinal
section at Figure 3. fis an axis passing across from side to side of the
framing below the board d at a point intermediate of its length, the axis f
has fixed upon it a blade or arm f¹which when the axis is turned can
be caused to press upwards against the under side of the board, so raising
the end of the board which carries the roller c, and causing this roller to
press against the roller b. The axis can be thus caused to turn by
pressing downwards a lever arm f', which is attached to one of its ends.
The lever arm when thus pressed down can be locked or held down
by a small tooth or projection upon it being caused to catch under one
or other of the teeth of a fixed rack g, the lever arm being for this
purpose made with a tendency to spring sidewise towards the rack. In
place of the arrangement above described for forcing upwards the board d
other arrangements might be employed for this purpose. As, for example,
a board d might be constantly pressed upwards by springs, and in this
case when it was desired to draw down the roller c from the roller b the
springs on the board might be pressed downwards by eccentrics or other-
wise. On the axis of the roller 6 upon which the sheet of canvas is
wound is a toothed wheel 6', which gears with an intermediate pinion h,
which also gears with a pinion k; this pinion is loose upon the short
axis, and can be slid endwise upon it. On the axis k' is fixed a fly
wheel k, which carries a crank handle by which the wheel can be turned.
Projecting outwards from the side of the pinion k is a small stud, which
by moving the pinion endwise along its axis towards the fly wheel can be
brought into position for a corresponding pin or stud on the boss of tho
fly wheel to strike against if the fly wheel be caused to revolve, and
thus the pinion and fly wheel will revolve together, but if the pinion k be
moved away from the fly wheel, then the fly wheel and the pinion may
revolve independently one of the other. In order thus to move the
pinion away from the fly wheel when the lever f' is raised, the lever is
then caused to act against an incline on a spring lever 1, which at its
lower end is fixed to the framing, and at its upper end carries a fork
which is received between two collars on the boss of the pinion k.
When the lever arm thus comes against the incline of the spring
lever it forces this lever aside, and thus the fork at its upper end is
caused to move the pinion endwise along its axis and away from the
fly wheel. When the lever armis aga in pressed downwards the spring
lever
will then press the pinion k back again towards the fly wheel.

I would however state that other arrangements for throwing the fly
wheel in and out of gear with the toothed wheel on the roller 6 may be
adopted in place of the arrangement above described.
In witness whereof, I, the said George Warsop, have hereunto set
my hand and seal, this Seventh day of July, in the year of our 5
Lord One thousand eight hundred and sixty-eight.
GEORGE WARSOP. (L.S.)
