IMPROVEMENTS IN THE CON- STRUCTION OF MANGLES
Year: 1862

page_text: LETTERS PATENT to Henry Nunn, of Chelsea, in the County of Mid-
dlesex, Whitesmith, for the Invention of "IMPROVEMENTS IN THE CON-
STRUCTION OF MANGLES."
Sealed the 19th September 1862, and dated the 26th March 1862.
PROVISIONAL SPECIFICATION left by the said Henry Nunn at the
Office of the Commissioners of Patents, with his Petition, on the 26th
March 1862.
I, HENRY NUNN, of Chelsea, in the County of Middlesex, Whitesmith,
do hereby declare the nature of the Invention of "IMPROVEMENTS IN THE
CONSTRUCTION OF MANGLES," to be as follows:-
The first part of my Invention has for its object improvements in the
mechanism employed for giving motion to the ordinary box mangle, or those
consisting of a heavy weight moving to and fro upon rollers supported in a
suitable frame; and my Invention consists in improved arrangements of the
mechanism employed for converting and transferring the continuous rotary
motion of the main driving axis into an alternating. rectilinear to-and-fro
movement of the travelling weight, this arrangement of mechanism being more
simple and less liable to injury or derangement than that usually employed,
and generally known as "Baker's mangle motion."
In constructing mangles according to my Invention, a central driving axis
is supported in suitable bearings on the side frames, and upon it a winch

page_text: handle and fly wheel may be fixed. Upon the driving axis there are two
loose pullies or drums to which chains or ropes are attached, the other ends
being attached to the opposite ends of the travelling box or weight. Between
the two loose pullies or drums there is a fixed boss on the driving axle, on
each side of which a pin or projection is fixed, which enters into holes or
recesses formed in the inner ends of the loose pullies or drums when they are
moved along the axis to engage and disengage alternately with the fixed boss by
which each pulley or drum is caused to wind up and unwind its rope or chain
alternately, and thus move the box and weight to and fro in its frame. The
loose pullies or drums are moved to and fro on the driving axis to reverse the
motion of the mangle by means of a sliding rod having projections thereon,
which embrace the flange of each pulley or drum. This rod is caused to slide
to and fro by levers which act alternately on each end of the sliding rod, the
levers which are attached to the frame being acted upon for this purpose by
.inclines fixed near each end of the box or travelling weight, so that when the
sliding rod is thus moved in either direction, one of the pullies on the driving
axis is disengaged from, and the other is caused to engage with the boss or
clutch fixed on the driving axis, by which arrangement the movement of the
box or travelling weight is alternately reversed. In place of this mode of
reversing the motion, the sliding rod may be moved to and fro by a pin at
each end entering into a curve or inclined slot formed on an axis moving in
bearings on the side frames. This axis is formed with lever arms, which are
acted upon alternately by projections fixed near each end of the box or moving
weight, or other mechanical means may be employed for throwing the loose
pullies or drums into and out of gear with the driving axis.
Another part of my improvements in mangles consists in arranging appa-
ratus for lifting the end of the box or travelling weight when it arrives at
either end of its journey. For this purpose, grooves or inclines are formed
on the sides of the box or travelling weight near each end; and when it is
desired to raise either end of the mangle, pins or projections are interposed on
the inner sides of the frame by the attendant, so as to act on the grooves or
inclines to raise the mangle, such pins or projections being connected by a rod
and lever so as to be acted upon simultaneously on each side of the box or
travelling weight.
Another part of my improvements in the construction of mangles.consists in
forming the box or moving weight in compartments, so that such compart-
ments may receive closed vessels containing water or other fluids or matters
capable of being readily discharged therefrom when required.

by the said Henry Nunn in the Great Seal Patent Office "on the 26th
September 1862.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I HENRY
NUNN, of Chelsea, in the County of Middlesex, Whitesmith, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters,
Patent, bearing date the Twenty-sixth day of March, in the year of our Lord
One thousand eight hundred and sixty-two, in the twenty-fifth year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto me, the
said Henry Nunn, Her special licence that I, the said Henry Nunn, my
executors, administrators, and assigns, or such others as I, the said Henry
Nunn, 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 THE CON-
STRUCTION OF MANGLES," upon the condition (amongst others) that I, the
said Henry Nunn, my executors or administrators, by an instrument in
writing under my, or their, or one of their hands and seals, should par-
ticularly 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 imme-.
diately after the date of the said Letters Patent.
NOW KNOW YE, that I, the said Henry Nunn, 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:-
The first part of my Invention has for its object improvements in the
mechanism employed for giving motion to the ordinary box mangle, or those
consisting of a heavy weight moving to and fro upon rollers supported in a
suitable frame; and my Invention consists in improved arrangements of the
mechanism employed for converting and transferring the continuous rotatory
motion of the main driving axis into an alternating rectilinear to-and-fro
movement of the travelling weight, this arrangement of mechanism being
more simple, and less liable to injury or derangement than that usually
employed and generally known as "Baker's mangle motion."
190
And in order that my improvements may be most fully understood and
readily carried into practice, I will proceed to describe a mangle constructed
according to my Invention.

page_text: DESCRIPTION OF THE DRAWING.
a is a central driving axis supported in suitable bearings a¹ on the side
frames b, and upon the axis a a winch handle a³ and fly wheel as are fixed.
Upon the driving axis a there are two loose pullies or drums c and c¹, to which
chains or ropes d are attached, the other ends being attached to the arms d'
fixed at opposite ends of the travelling box or weight e. Between the two
loose pullies or drums c and c¹ there is a fixed boss c² on the driving axis, on
each side of which a pin or projection c³ is fixed, which enters into holes or
recesses formed in the inner ends of the loose pullies or drums c, c', when they
are moved along the axis to engage and disengage alternately with the fixed
boss c, by which each pulley or drum is caused to wind up and unwind its
rope or chain alternately, and thus move the box and weight to and fro in its
frame. The loose pullies or drums c and c' are moved to and fro on the
driving axis a to reverse the motion of the mangle by means of a sliding rod f
having projections thereon at each end, which embrace the outer flange of
cach pulley or drum c, c¹. The sliding rod f is moved to and fro by a pin f
at each end thereof, entering into a curve or inclined slot formed on the
axis g, moving in bearings on the side frames b. The axis 9 is formed with
Jever arms g', which are acted upon alternately (when the box e reaches the
end of its movement in either direction by projections fixed near each end of
the box or moving weight. Or this sliding rod f may be caused to slide to
and fro by levers carried by studs on the side frames 6, which levers act alter-
nately on each end of the sliding rod f, the lever being acted upon for the
purpose of reversing the movement of the box e by inclined or projections fixed
near each end of the box or travelling weight, so that when the sliding rod f
is thus moved in either direction, one or other of the pullies c or c¹ on the
driving axis a is disengaged from, and the other is caused to engage with the
boss or clutch c³ fixed on the driving axis a, by which arrangement the move-
ment of the box or travelling weight e is alternately reversed; or other
mechanical means may be employed for throwing the loose pullies or drums
into and out of gear with the driving axis.
Another part of my improvements in mangles consists in arranging apparatus
for lifting the end of the box or travelling weight when it arrives at either end
of its journey. For this purpose grooves or inclines 62 are formed on the
sides of the box or travelling weight e near each end, and when it is desired
to raise either end of the mangle, the pins or projections h are interposed on
the inner sides of the frame 6 by the attendant, so as to act on the grooves or
inclines to raise one end of the box e at either end of its moveinent. The

page_text: pins or projections h are connected by a rod h¹ and lever h³, so as to be acted
upon simultaneously on each side of the box or travelling weight e, projections
or inclines on which force back the pins h.
Another part of my improvements in the construction of mangles consists
in forming the box or moving weight in compartments, so that such com-
partments may receive closed vessels containing water or other fluids or
matters capable of being readily discharged therefrom when required. The
mangle is so constructed that the parts can be readily separated and packed
together in the box e in a compact form for transit or exportation..
In witness whereof, I, the said Henry Nunn, have hereunto set my
hand and seal, this Twenty-fifth day of September, in the year of
our Lord One thousand eight hundred and sixty-two.
Witness,
