IMPROVEMENTS IN THE CONSTRUCTION OF MANGLES
Year: 1858

page_text: LETTERS PATENT to Thomas Wilson, of Bradmore House, Chiswick, in
the County of Middlesex, for the Invention of "IMPROVEMENTS IN THE
CONSTRUCTION OF MANGLES."
Scaled the 3rd December 1858, and dated the 3rd June 1858
PROVISIONAL SPECIFICATION left by the said Thomas Wilson at the
Office of the Commissioners of Patents, with his Petition, on the 3rd
June 1858.
I, THOMAS WILSON, of Bradmore House, Chiswick, in the County of
Middlesex, do hereby declare the nature of the said Invention for "IMPROVE-
MENTS IN THE CONSTRUCTION OF MANGLES," to be as follows:-
This Invention consists of certain mechanical arrangements to be applied to
"box mangles," for the purpose of obtaining a forward and backward move-
ment of the "box," with one continuous motion of the driving shaft. To effect
this object I propose placing on the main shaft two flanged rollers fitting
loosely on the shaft, and having ways cut across their inner ends to correspond
.with projections on the centre of shaft; chains are attached from each end
of the "box," to separate rollers, the chains working one over one roller, the
other under the other roller, and in order to put these rollers in or out of gear
I affix two inclined planes on the upper surface of the "box," one at each end
thereof. These inclined planes present themselves alternately to the rollers,
and touching the flanges on their outer ends force the rollers either into or out
of gear. A pin being between them, as one is put into action it pushes the
other out, allowing it to run freely on the shaft and unwind the chain until tho
box returns, when the other roller is then put into gear. For the purpose of
lifting the ends of the "box," I place a stud pin at each end thereof near the
top, and on the side and on the mangle frame are placed two standards

page_text: attached to each other by pins or rivets, said pins or rivets passing through
slots cut in one of the standards, which works up and down on said pins. At
the bottom of the moveable standard are two projecting arms, the ends whereof
take under the stud pins in the ends of the "box," and so raise it. The box
having been released from the end pin, the moveable standard is raised on the
"box" reaching the centre by having a double inclined plane on its upper edge,
which prevents the box being again raised at either end until the standard is
pushed down by the hand.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Thomas Wilson in the Great Seal Patent Office on the 3rd
December 1858.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, THOMAS
WILSON, of Bradmore House, Chiswick, in the County of Middlesex, send
greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Third day of June, in the year of our Lord One
thousand eight hundred and fifty-eight, in the twenty-first year of Her reign,
did, for Herself, Iler heirs and successors, give and grant unto me, the said
Thomas Wilson, Her special licence that I, the said Thomas Wilson, my
executors, administrators, and assigns, or such others as I, the said Thomas
Wilson, 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 CONSTRUCTION
OF MANGLES," upon the condition (amongst others) that I, the said Thomas
Wilson, my executors or administrators, by an instrument in writing under
my, or their, or one of their hands and scals, 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 Thomas Wilson, 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 consists of certain mechanical arrangements to be applied to

page_text: "box mangles," for the purpose of obtaining a forward and backward move-
ment of the "box" with one continuous motion of the driving shaft, and to
raise either end of the mangle, as required, in a more casy and efficient manner
than heretofore.
In order to explain my said Invention as completely as possible, I now
proceed to describe the best means I am acquainted with for carrying the same
into practical effect, reference being had to the illustrative Shect of Drawings
hereunto annexed, and to the numeral figures and letters of reference marked
thereon respectively, as follows:-
DESCRIPTION OF THE DRAWING.
Figure 1 is a top plan view, Figure 2, an end view, Figure 3, side view
of upper part of mangle, and Figure 4, section of centre wheel and shaft
through A, B, Figure 3. Similar letters of reference denote corresponding
parts in so far as such parts appear or can be seen at each of such said
Figures respectively.
At Figures 1 and 2 will be seen a shaft a running across the centre of the
mangle frame, and supported at each end by metallic standards b, b; at ono
end of said shaft a is placed a fly wheel c; at the other a winch bandle d.
On the shaft a are mounted two flanged rollers e, e', and between the inner
flanges of these rollers is a wheel f, the boss of which revolves freely on the
centre part of the shaft a (which is here made larger), and between a double-
headed key g; this key moves freely from side to side in a groove h, cut in the
centre of the shaft a, as at Figure 4, for the purpose of bringing the one or
other end of the key g into contact with projections i, on the surface of the inner
flanges of the rollers e, e¹, as will be seen at Figures 1 and 2, where the roller
el is in gear with the key head, while the roller e being out of gear revolves
freely on the shaft a, and allows the cord, gut, or chain to unwind of its own
accord until the end of the box is brought near the wheel f, when the inclined
or A-shaped piece o coming into contact with the edge of the wheel drives
it towards the roller e, at the same time carrying with it the key g travelling
in the groove h, until the other end of the key 7 touches another projection on
the flange of the roller e, when the box of the mangle moves in a contrary
direction, more clearly understood by reference to the arrow's flight on the
annexed Drawing, where the box is now moving from right to left.
When it is necessary to raise either end of the mangle, the same is done by
pulling the small handle k from the standard on the mangle frame, which it
will be seen moves on a pin at its centre, the extremity of which is also jointed
to a short rod passing through the standard and secured to a double incline 1;

page_text: studs m are placed on the sides of the box, which on reaching the incline
travel up it, thereby lifting the end of the mangle; to prevent the other end
of the mangle being raised before required, it is merely necessary to push the
handle back against the standard, which has the effect of drawing the
double incline close up to the standard, thereby allowing the studs m to pass
in front of it. This incline may be made to move up and down (instead of
in and out) allowing the studs m to pass under instead of in front.
Should it at any time be required to reverse the motion suddenly, the same
may be effected without stopping the motion of the winch handle by reaching
over to the wheel f, and either pulling or pushing it out of gear with one of
the rollers e or e¹ into gear with the other. Should either of the cords break
while the box is in full motion, it is prevented running off the end of the frame
by the studs m coming against stops or car pieces n, on the upper part of the
incline; this incline rides upon guides cast upon the lower part of the standard,
said incline having narrow arches cut therein, corresponding with the pro-
jections on the standard.
Having now fully described and set forth the nature and object of my said
Invention of "Improvements in the Construction of Mangles," together with the
best means I am acquainted with for carrying the same into practical effect, I
would remark in conclusion that I do not confine or restrict myself to the
precise details as herein described and shewn by the hereunto annexed illus-
trative Sheet of Drawings, as many slight modifications may be made without
in any way departing from the principle of my Invention; but what I claim as
my Invention, intended to be secured to me by the herein in part recited Letters
Patent, is, the peculiar mode of producing reciprocating motion as applied to
mangles, by pushing two or more drums or cylinders in and out of gear, and
other parts shewn by the annexed Drawing, for the purposes herein described
and set forth.
In witness whereof, I, the said Thomas Wilson, have hereunto set my
hand and seal, this Third day of December, in the year of our Lord
One thousand eight hundred and fifty-eight.
