Year: 1871

page_text: LETTERS PATENT to Thomas Unsworth, of Manchester, in the County
of Lancaster, Banding Manufacturer, for the Invention of "Iм-
PROVEMENTS IN MACHINERY FOR MAKING BANDING CORD OR OTHER SUCH
LIKE ARTICLE."
Sealed the 12th September 1871, and dated the 25th April 1871.
PROVISIONAL SPECIFICATION left by the said Thomas Unsworth at
the Office of the Commissioners of Patents, with his Petition, on
the 25th April 1871.
I, THOMAS UNSWORTH, of Manchester, in the County of Lancaster,
Banding Manufacturer, do hereby declare the nature of the said
Invention for "IMPROVEMENTS IN MACHINERY FOR MAKING BANDING CORD OR
OTHER SUCH LIKE ARTICLE," to be as follows:-
The above Invention consists in certain improvements made by me
in a machine for which a Patent was granted to me and Edward Walley
on the 13th day of August 1870, and by such improvements I am
enabled to make in addition to the articles therein enumerated "spindle
banding of a mixture of wire and other fibrous material," likewise

page_text: fishing lines, fishing net twine, jacquard machine twine, and all such
like cords in which great strength and durability is required.
"
I fix on the top "of" and at the back of my machine "aforesaid "
two stretching roller shafts on which I fit a suitable number of stretch-
ing pullies grooved to recieve the strands from the back bobbins. Such
strands passing several times round the two sets of pullies it passes over
the machine to the front stretching pullies, as used by me in my
former machine, with the difference of my using "now" conical pullies
(grooved) instead of straight ones as before, "and as I may use now
for certain work (at the back). The strands are then passed to the
finnishing flyers and bobbins as before. I-effect my stretching by change
wheels as before. I likewise place a number of tension levers with
moveable weights which act upon the strands between the back and
front stretching pullics, by which I can put equal tension on cach
strand, and thus prevent cork-screwed cord. It has likewise the effect
of casing the back spindles while the strands are coming from the
bobbins, which "also" prevents cork-screwing. I likewise fix at the
back of the machine a double row of spindles and flyers. On the bobbin
plates I fix under each bobbin a friction plate pulley with a flange that.
fits under the friction lever, which prevents such. from rising up when
in motion, and underneath, such, pullies I cast a bush to prevent "such"
from coming in contact with the spindles when in motion.
For fine cords in which I require extra turns to the inch, I apply a
countershaft with grooved pullies which I connect by gearing or
friction, and by such means obtain whatever speed I require, and from
such grooved pullies I drive my spindles.
I drive the whole by means of a drum or drums, vertical or horizontal

WHEREAS Her most Excellent Majesty Queen Victoria, by. Her
Letters Patent, bearing date the Twenty-fifth, day of April, in the year 3

page_text: of our Lord One thousand eight hundred and seventy-one, in tlic thirty-
fourth year of Her reign, did, for Herself, Her heirs and successors, give
and grant unto me, the said Thomas Unsworth, Her special licence
that I, the said Thomas Unsworth, my executors, administrators, and
assigns, or such others as I, the said Thomas Unsworth, my executors,.
administrators, and assigns, should at any time agreo 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 MACHINERY
FOR MAKING BANDING CORD OR OTHER SUCH LIKE ARTICLES," upon the con-
clition (amongst others) that I, the said Thomas Unsworth, 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 sanic was to
be performed, and cause the same to be filed in the Great Scal 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 Unsworth, 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
This Invention relates "to," and consists" of," certain improvements in
a machine patented by me and Edward Walley on the 13th day of
August 1870, enabling me to make the articles therein enumerated
of a better quality, "and in addition" spindle banding of a mixture of
wire and any fibrous material, "fisliing lines," "fishing net twine,"
"jacquard machine twine," and all cords where great strength and
durability is required. I use the same means for winding my strands
as in the before-mentioned machine; "and for doubling" I place the
bobbins in a similar position at the back of the machine, "but," instead
of having, as therein, a similar number of spindles back as front I place
two, three, "or more" rows of spindles, according to the requirements.
I likewise apply a spring tension lever to one or both legs of my back
flyers, which keeps tight the strands on leaving the bobbins for doubling.
At the back of the machine I fix a stretching motion similar to the one
I use in front, and described in our former Patent liérein refered to;
"but," instead of doubling such strands before stretching, I stretch

page_text: each strand separately by passing them several times round conical or
other shaped pullies grooved with flat-bottomed grooves, or any other
shape suitable to my requirements. The strands are then passed
through a trough of water (if desired), thence to the front stretching
motion where they are doubled, and again stretched over conical or other
shaped pullies (with flat-bottomed grooves turned in them), and is
twisted and finished by front spindles and flyers and wound on bobbins.
For fine cords, sewing cotton, or thread, where great speed is required,
I use a countershaft driven from main shaft by strap or wlicels, on
which are any number of grooved pullies my demands shall dictate. In
place of the cop board I use two circular cop tables placed in any
convenient position; such are made to revolve at the will of the minder.
Hereunto is annexed a Sheet of Drawings, in the several Figures of
which similar parts are marked by corresponding letters of reference.
Fig. 1 is a front view of my machine, which is similar in every
respect to the "before-mentioned Patent," with the addition of some of
my improvements, as cop table "A," driving gear for back stretching
motion "b," and counter driving shaft “c.",
Fig. 2 is back view of my machine shewing arrangement of
bobbins" d," back stretching motion "," and spring tension levers "Z."
Fig. 3 is right hand side view of my machine shewing ends of back
stretching motion shafts with course of strands from back bobbins over
back stretching motion "e" into water trough "J," and to front
stretching motion "g." Likewise countershaft end "c," and cop tables
A and B, and counter pullies "V."
Fig. 4 is left hand side view of my machine shewing the gearing by
which I drive my back stretching motion; likewise the gearing "r," by
which I drive my countershaft "c" from main shaft "A 1."
Fig. 5 is a plan of my machine shewing (by preference), a double
row of back "spindles, bobbins, and flyers," with the several strands
dotted from back spindles and bobbins "" to back stretching motion "e"
in single lines, thence through water trough "J" to front stretching
motion "g," "where it is doubled"; thence to front spindles and
flyers"."
The strands are wound from cops on tables "A" and "B," over top
guide bars "C" to rollers "D," from thence to flyers "E" and
bobbins "
F," as in my former Invention mentioned herein. The

page_text: bobbins "F," when full, are moved to the back spindles of the machine,
and are then bobbins "h." Each strand from such bobbins is passed
through "eyclet" hole in the end of spring tension lever "Z" on the
leg of back flyer "n," through the eye of flyer leg and end of spindle,
and from thence to back stretching motion "e." Each single strand is
passed several times round the conical or other shaped pullics and is
stretched singly to any required tension before doubled; it is then passed
across the machine to front stretching motion, where it is doubled, and
again stretched, twisted, and passed to bobbins "m" finished cord.
It will thus be seen that by my present Invention I obtain quite a
double and I may say almost a treble process of stretching, as by the
"tension lever on flyer leg," "the back motion ""and front motion,"
consequently, a regular, tight, and evenly twisted band or cord; and by
the conical pullics a gradually increasing power is exercised on the
strands before they become finally twisted into cord.
And now having described the nature of my said Invention, and the
way in which the same may be applied, I may as well state in con-
clusion that I do not confine myself to the "precise" details I have
herein described, as many variations may be made in detail without
deviating from the principle; but I claim as novel and secured to me
by these Presents is,―
First. The method of double stretching by and over conical or other
grooved pullies, as herein described.
Second. The application of a back stretching process, as herein
described and illustrated.
Third. The revolving cop tables, substantially as herein described and
illustrated.
Fourth. The counter shaft as applied to this machine, herein described
and illustrated, for increasing speed for fine cords.
Fifth. The application of spring tension levers to the leg or legs of
back flyers, as herein described and illustrated.
Sixth. The method and arrangement of two, three, or more rows
of spindles and flyers àt the back of the machine, as herein-before
described.
Seventh. The application of a pair of metal friction clips to the
bottom friction plates under each bobbin at the front of the machinc

page_text: Eighth. The general arrangement of the several parts claimed by these
Presents; as set forth and illustrated.
In witness whereof I, the said Thomas Unsworth, have hercunto
set my land and scal, this Twenty-sixth day of September, in the
year of our Lord One thousand eight hundred and seventy-one.
