IMPROVEMENTS IN MANGLES, APPLICABLE ALSO TO WRINGING MACHINES."
Year: 1880

page_text: LETTERS PATENT to William Blannie Dick, of Langley Mill, in the County
of Nottingham, for an Invention of " IMPROVEMENTS IN MANGLES, APPLICABLE
ALSO TO WRINGING MACHINES."
PROVISIONAL SPECIFICATION left by the said William Blannie Dick at
the Office of the Commissioners of Patents on the 8th April 1880.
WILLIAM BLANNIE DICK, of Langley Mill, in the County of Nottingham.
"IMPROVEMENTS IN MANGLES, APPLICABLE ALSO TO WRINGING MACHINES."
This Invention mainly consists of a flat spiral spring enclosed in hollow column
which forms part of the frame, and which is cast with it, carrying the rollers of
the manglo or wringer, as the case may be, said frame being so designed that it
combines lightness with strength, the top being cast solid, and not open throughout
as in other mangles which require a heavy bridge to add increase of strength to
the frame. The spring is made preferably of flat steel bent spirally, so that the
thin edges face each other, forming a spiral spring, with, say, 1/18 of an inch open
every inch and a quarter or thereabouts. The top of the spring bears on bottom
of bearing, which is let about two inches into the top of the hollow column with a
T head, with a hollow taken out of head to fit into roller journal. The bottom of
spring rests on a seat at bottom of column, the hole in column being reduced in
size about an inch from bottom so as to form seat for bottom of spring. The
mangle and wringer is so geared that the wheels connecting the two rollers are
both on driving side and not on extreme end of roller, as in other mangles, thereby
diminishing the liability to twist the roller axles, and the bottom roller is preferably.
made the driving roller.
Advantages gained by my Invention are:-
(1.) The spring does away with all weights, screws, and heavy springs at top
and bottom as are now gonerally used in other mangles.
(2.) The spring acts directly on the bearings of the roller, and being inside the
column is completely out of view.
(3.) The spring when at work increases pressure according to work done without
the use of screws.

"IMPROVEMENTS IN MANGLES, APPLICABLE ALSO TO WRINGING MACHINES.”
This Invention consists of a flat spiral spring enclosed in hollow column which
forms part of the frame, and which is cast with it, carrying the rollers of the
mangle or wringer, as the case may be, said frame being so designed that it
combines lightness with strength. The top is cast solid, and not open throughout
..as in other mangles which require a heavy bridge to increase strength of the frame.
The spring is made preferably of flat-steel bent spirally, so that the thin edges faco
each other, forming a spiral spring with, say, 1/8 of an inch open every inch and a
quarter or thereabouts. The top of spring bears on bottom of bearing, which is
let about two inches into the top of hollow column with a T head, with hollow
taken out of head to fit into roller journal. The bottom of spring rests on a seat
at bottom of column, the hole in column being reduced in size about an inch from
bottom so as to form seat for bottom of spring. The mangle and wringer is so
geared that the wheels connecting the two rollers are both on driving side and not
on extreme end of roller as in other mangles, thereby diminishing the liability to
twist the roller axles, and the bottom roller is preferably made the driving roller,
the whole, as combined, constituting my improvements.

Fig. 2, end elevation.
A, frame with hollow column B cast with it; C, spring of flat steel enclosed in
column B, part of column B in Fig. 1 being broken away to show spring. The top,
of spring bears against bottom of bearing at D, and the bottom rests on a seat G,
the lower part being reduced in size.
Advantages gained by my Invention are:-
(1.) The spring does away with all weights, screws, and heavy springs at top and
bottom as are now generally used in other mangles.
(2.) The spring acts directly on the bearings of the roller, and being inside the
column is completely out of view.
(3.) The spring when at work increases pressure according to work done without
the use of screws.
Having now particularly described and ascertained the nature of the said
Invention, and in what manner the same is to be performed or carried out in
practice, I hereby declare that I claim the Invention of "Improvements in Mangles,
Applicable also to Wringing Machines," substantially as hereinbefore set forth and
described and illustrated by the accompanying Drawings.
In witness whercof, I, the said William Blanuie Dick, havo hereunto set my
hand and seal, this Seventh day of October, in the year of our Lord One
thousand eight hundred and eighty.
