page_text: LETTERS PATENT to Henry Nunn, of No. 41, Lower George Street,
Sloane Square, Chelsea, in the County of Middlesex, Whitesmith, for
the Invention of "AN IMPROVED MANGLE."
the Invention of "AN IMPROVED MANGLE."
Sealed the 15th August 1865, and dated the 24th May 1865.
PROVISIONAL SPECIFICATION left by the said Henry Nunn at the
Office of the Commissioners of Patents, with his Petition, on the 24th
May 1865.
I, HENRY NUNN, of No. 41, Lower George Street, Sloane Square, Chelsea,
in the County of Middlesex, Whitesmith, do hereby declare the nature of
the said Invention for "AN IMPROVED MANGLE," to be as follows:-
This improved mangle is constructed with a frame, bed, box, and rollers,
similar to an ordinary mangle, the improvements being principally in the
working parts or mechanism employed for giving the requisite to-and-fro
motion to the box, whereby I dispense entirely with toothed gearing. A shaft
having a handle at one end and a fly wheel at the other is supported on two
standards fixed to the upper part of the frame, so that the shaft extends across
the middle of the mangle above the box. Upon this shaft are two rollers or
barrels mounted loosely, but capable of being thrown into or out of gear with
the shaft by a sliding clutch box or other equivalent device being so arranged
with respect to each other that when one is in gear with the shaft the other
is free to turn thereon, and vice versâ. To each of these barrels one end of a
band is fixed, the other end of each band being either fixed to a bracket at the

page_text: extreme end of the box, or it may pass round a roller at this point, and its
end be fixed to a rod or bar, which connects the two standards. The sliding
clutch box is provided with a lever for throwing it into or out of gear with the
rollers or barrels, and this lever is actuated by two projecting pieces fixed one
at or near each end of the box.
The action is as follows:-The shaft is always turned in the same direction,
as in the ordinary mangle, and it will be evident that whichever roller or
barrel is in gear with the shaft will coil its band on to itself, and thus pull the
box of the mangle in one direction, whilst the other band uncoils itself from
its roller, which runs free on the shaft. As soon as the box has arrived at or
near the end of its course one of the projecting pieces above named comes into
contact with the clutch lever, and slides the clutch into gear with the other
roller or barrel, which was before loose, and casts loose the one which was in
gear. The other roller immediately commences to coil up its band and pull
the box in the reverse direction, and so on alternately. A handle is provided
by means of which the person attending to the mangle can at any time reverse
the mangle by sliding the clutch box.
The lifting action is obtained by inclined planes of metal screwed to each
side of the box, a small knob being provided near the centre of the frame, by
pressing which a pin is thrown out at each side, which coming under the
inclined planes raises the box off the rollers.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
the said Henry Nunn in the Great Seal Patent Office on the 19th
September 1865.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, HENRY
'NUNN, of No. 41, Lower George Street, Sloane Square, Chelsea, in the
County of Middlesex, Whitesmith, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Twenty-fourth day of May, in the year of our Lord One
thousand eight hundred and sixty-five, in the twenty-eighth 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,

page_text: 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 Henry Nunn,
my executors or administrators, by an instrument in writing under my, or
their, or one of their hands and seals, should particularly describe and ascer-
tain 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 Henry Nunn, 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 in writing, and on reference being had to the accompanying Sheet
of Drawings, that is to say:-
This improved mangle is constructed with a frame, bed, box, and rollers,
similar to an ordinary mangle, the improvements being principally in the
working parts or mechanism employed for giving the requisite to-and-fro
motion to the box, whereby I dispeuse entirely with toothed gearing. A shaft
having a handle at one end and a fly wheel at the other is supported on two
standards fixed to the upper part of the frame, so that the shaft extends across
the middle of the mangle above the box. Upon this shaft are two rollers or
barrels mounted loosely, but capable of being thrown into or out of gear with
the shaft by a sliding clutch box or other equivalent device, being so arranged
with respect to each other that when one is in gear with the shaft the other
is free to turn thereon, and vice versa. To each of these barrels one end of a
band is fixed, the other end of each band being either fixed to a bracket at
the extreme end of the box, or it may pass round a roller at this point, and its
end be fixed to a rod or bar which connects the two standards. The sliding
clutch box is provided with a lever for throwing it into or out of gear with the
rollers or barrels, and this lever is actuated by two projecting pins fixed one at
or near each end of the box.
The action is as follows:-The shaft is always turned in one direction, as in
the ordinary mangle, and it will be evident that whichever roller or barrel is
in gear
with the shaft will coil its band on to itself, and thus pull the box of
the mangle in one direction, whilst the other band uncoils itself from its roller
which runs free on the shaft. As soon as the box has arrived at or near the
end of its course, one of the projecting pins above named comes into contact
with the clutch lever, and slides the clutch into gear with the other roller or
barrel, which was before loose, and casts loose the one which was in gear.

page_text: The other roller immediately commences to coil up its band and pull the box
in the reverse direction, and so on alternately. A handle is provided by
means of which the person attending to the mangle can at any time reverse
the mangle by sliding the clutch box.
The lifting action is obtained by inclined planes of metal screwed to each
side of the box; a small knob being provided near the centre of the frame, by
pressing which a pin is thrown out at each side, which coming under the
inclined planes raises the box off the rollers.
Such being the nature and object of my said Invention for "An Improved
Mangle," I will now proceed to describe more in detail the manner in which
the same is to be or may be performed or carried into practical effect; and in
order that the same may be distinctly understood I have annexed hereunto a
Sheet of Drawings illustrative thereof, and have marked the same with
figures and letters of reference corresponding with those in the following
explanation thereof, that is to say :--
a side
In the annexed Drawing, Figure 1 is a plan view, Figure
elevation, and Figure 3 a transverse section of an improved mangle made
according to my Invention.
a, a, is the frame; b, b, the bed; c, c, the box; and d, d, the rollers; e, e, is the
fly wheel shaft supported by the standards f. f; 9, 9, is the fly wheel, and h, h,
the winch handle. On the shaft e, e, are mounted loosely the two rollers or
barrels i, i*, which are capable of being thrown into or out of gear with the
shaft e, e, by means of the clutch box k, k, the latter being so constructed and
arranged that whenever one roller or barrel is locked to the shaft, the other is
free to turn loosely thereon. To each of the rollers or barrels i, i*, is fixed
one end of a band 1, 1*, each of the said bands passing round a pulley m, m*,
mounted at one end of the box c, c, and its other end being fixed to one of the
rods n, n*, or (if preferred) the ends of the bands may be fixed respectively
to two brackets or fixtures attached to the box at m, m*.
For the purpose of throwing the barrels i, i, alternately into and out of
gear with the shaft e, e, either the barrels i, *, or the clutch box k, k, may be
made to slide on the shaft, the former being the plan shown in the Drawing
(see Figure 3).
It will be seen that the outer flange of each barrel is embraced by a clip o, o,
the said clips being connected together and mounted loosely on a rod p, p.
This rod has two pins projecting from it passing each through an inclined slot
in one of the clips o, o, in such a manner that upon partially rotating the
rod p, p, the clips with their barrels will be caused to slide to the right or left,
according to the direction in which the rod is turned; this partial rotation

page_text: of the rod p, p, is caused by a lever q, q, against which two pins r, r, act; one
of the said pins being fixed near to each end of the box. At one end of the
rod
P. P. is a lever handle 8, s, by means of which the action of the mangle
can be reversed instantaneously in any position of the box.
For lifting the box each side of the mangle is provided with two inclined
planes of metal t, t, screwed to the box, and two pins u, u, passing through the
frame, and these pins are so connected together by a lever v, v, (as seen in
Figure 3) that they can be both thrown in or out simultaneously by means of
the knob w, w.
Figure 4 is a transverse section, and Figure 5 a plan view of a modification
of part of the above, wherein the bands are dispensed with, and flexible
chains a, a, substituted; these chains are fixed at both ends to the box, and
are acted upon by spur wheels y, y, fixed to the ends of the barrels, the latter
being thrown alternately in and out of gear with the fly wheel shaft by means
of clutch plates at each end (not shown in the Drawing), so that the chain acts
as a flexible rack, and the piuions drag the box backwards and forwards
alternately as above described.
Having now described the nature and object of my said Invention, for
"An Improved Mangle," together with the manner in which the same is to
be or may be performed or carried into practical effect, I would remark in
conclusion that I claim as my Invention the improved mangle represented in
the Drawings and above described, or any mere imitation or modification
thereof, constructed and operating in substantially the same or a similar
manner.
In witness whereof, I, the said Henry Nunn, have hereunto set my
hand and seal, this Nineteenth day of September, in the year of our
Lord One thousand eight hundred and sixty-five.
HENRY NUNN. (L.S.)
