Year: 1880

page_text: LETTERS PATENT to John Gledhill, of Parkwood Mills, Longwood, near
Huddersfield, in the County of York, Manufacturer, and William Cliffe, of
Ley Moor, Golcar, near Huddersfield aforesaid, Machine Maker, for an
Invention of "IMPROVEMENTS IN THE METHOD OF AND APPARATUS FOR
MANUFACTURING WOOLLEN AND OTHER YARNS."
PROVISIONAL SPECIFICATION left by the said John Gledhill and William
Cliffe at the Office of the Commissioners of Patents on the 17th January 1880.
JOHN GLEDHILL, of Parkwood Mills, Longwood, near Huddersfield, in the
County of York, Manufacturer, and WILLIAM CLIFFE, of Ley Moor, Golcar, near
Huddersfield aforesaid, Machine Maker. " IMPROVEMENTS IN THE METHOD OF AND
APPARATUS FOR MANUFACTURING WOOLLEN AND OTHER YARNS."
This Invention relates to a method of manufacturing yarns composed of two or
more threads, and its principal object is to double and spin two or more threads of
the same or different colors together at one operation, and thereby dispense with
the separate operations of spinning each separate thread and twisting or doubling
them together afterwards as at present. Our improvements (by preference) consist
in the use and employment of a pair of rubbing belts or rollers, through or between
which is passed two or more threads which are rubbed bodily or squeezed into one
thread, and from thence are wound upon one condenser bobbin.
The bobbins are afterwards placed on a mule and the doubled or squeezed
threads are spun and twisted as one thread, producing a yarn of the same or
varigated color according to the color of the threads employed. Instead of using
rubbing belts or rollers we may pass two or more threads through guide eyes or
"raddles" direct onto one bobbin, which are afterwards united and doubled and
spun into one thread or yarn.
The Invention also relates to a method of making spotted yarn, and the improve-
ments consist in placing a pair of drawing or feeding rollers in combination with
the above arrangement of rubbing belts and in imparting an intermittant motion
to such feed rollers, so that when the feed rollers are stationary the rubbers, which
have a continuous revolving motion, will take or pull a given length off another or
third thread held fast by the feed rollers, and the piece thus pulled off is rubbed
onto the doubled or mixed thread which is also passing through the rubbers,
thereby producing spots or knots on the said mixed yarn at given distances apart.
Instead of the spotted yarn being a double or mixed thread it may be single.

JOHN GLEDHILL, of Parkwood Mills, Longwood, near Huddersfield, in the
County of York, Manufacturer, and WILLIAM CLIFFE, of Ley Moor, Golcar, near
Huddersfield aforesaid, Machine Maker. "IMPROVEMENTS IN THE METHOD OF AND
APPARATUS FOR MANUFACTURING WOOLLEN AND OTHER YARNS."
This Invention relates to a method of manufacturing yarns composed of two or
more threads, and its principal object is to double and spin two or more threads of
the same or different colors together at one operation, and thereby dispense with
the separate operations of spinning each separate thread, and twisting or doubling
them together afterwards as at present.
Our improvements (by preference) consists in the use and employment of a pair
of rubbing belts or rollers, through or between which is passed two or more threads
which are rubbed bodily or squeezed into one thread, and from thence are wound
upon one or more condenser bobbins.
In order that this Invention may be better understood we herein give reference
to the accompanying Sheets of Drawings, wherein Fig. 1 is an end elevation of
what is known in the woollen trade as a "rubber condenser machine," and Fig. 2
is cross section of the same. A and B are condenser bobbins containing the
threads a and b, which are intended to be formed or rubbed into one thread, and
this is accomplished by passing the said threads through the guide eyes or over the
raddles C and through the rubbing belts D, by which means the two threads are
united forming one solid thread, such thread passing in the direction of the arrows
to other condenser bobbins E and F.
These newly filled bobbins are afterwards removed to the mule and the doubled
or squeezed thread are spun and twisted as one thread, producing a yarn of the
same or varigated color according to the color of the threads employed. By these
means we obtain a doubled thread at one spinning operation.
Instead of using rubbing belts for uniting the threads rollers G and H, as shewn
at Fig. 3, may be used; Fig. 4 illustrates an arrangement by which both the rubbers
and rollers may be dispensed with, and the threads guided by guide eyes and
raddles C from condenser bobbins A and B onto bobbins E and F, which in being
wound onto the bobbins adhere together sufficiently as to be twisted and spun into
one thread on the mule.
The Invention also relates to a means of making spotted yarn, and the improve-
ments consist in placing a pair of drawing or feeding rollers in combination with
the above arrangement of rubbing belts and in imparting an intermittent motion
to such feed rollers, so that when the feed rollers are stationary the rubbers, which
have a continuous revolving motion, will take or pull a given length off another
or third thread held fast by the feed rollers, and the piece thus pulled off is rubbed
onto the doubled or mixed thread which is also passing through the rubbers,
producing spots or knots on the said mixed yarn at given distances apart.
This part of the Invention is illustrated in Fig. 5 (Sheet 3), which is an end
elevation of the condenser machine, as previously referred to, and Fig. 6 is cross
section of same. The threads a and b pass over the raddles C and under the feed
rollers H to the rubbers D, and c is another or the third thread of a different color
which passes between the feed rollers H and between the rubbers. The feed rollers
have an intermittent motion given to them, so that when they stand or dwell the
rubbing belts which are revolving will nip or break a piece off thread C, such
broken piece being carried forward by the rubbers and rubbed into the united
thread a and b, making a spotted or knotted yarn.
The feed rollers receive their intermittent motion from the pegs d on the wheel I,

page_text: which lifts the lever J moving the ratchet wheel K, and communicating its inter-
mittent motion through the chain L and train of gearing M and N to the feed
rollers. The motion of the feed rollers may be varied by altering the speed of the
wheel I or by increasing or decreasing the number of pegs d. Although we have
shewn on the Drawings the application of the thread c for the purpose of leaving
spots on the double thread a and b, it is obvious that a single thread may be
employed instead of a double thread.
Having now described the nature of our Invention, and the manner in which
the same is to be performed, we wish it to be understood that we do not limit
ourselves to the precise details herein before described and illustrated in the
accompanying Drawings, as the same may be varied without departing from the
nature of our Invention; but we claim as our Invention,-
Firstly. The means or methods, herein shewn in Figs. 1 and 2, for uniting threads
a and b for the purposes of spinning and twisting them into one thread,
substantially as described.
Secondly. The means or methods, shewn in Figs. 3 and 4, for uniting threads a
and b for the purposes of spinning and twisting them into one thread, substantially
as described.
Thirdly. The means or method, shewn in Figs. 5 and 6, for making spotted or
knotted threads previous to the spinning operation, substantially as herein shewn
and described.
In witness whereof, we; the said John Gledhill and William Cliffe, have
hereunto set our hands and seals, this Seventh day of July, in the year
of our Lord One thousand eight hundred and eighty.
