and Speddings, of Dewsbury, in the County of York, Manufacturers, and
Joseph Henry Robertshaw, of Ravensthorpe, in the said County, Overlooker,
for the Invention of "IMPROVEMENTS IN MACHINERY FOR SPINNING, DOUBLING,
TWISTING, OR WINDING WOOL, WORSTED, COTTON, OR OTHER FIBROUS SUB-
STANCES."

Sealed the 15th August 1879, and dated the 19th February 1879.

Joseph Henry Robertshaw at the Office of the Commissioners of Patents on
the 19th February 1879.

Dewsbury, in the County of York, Manufacturers, and JOSEPH HENRY ROBERTSHAW,
of Ravensthorpe, in the said County, Overlooker. "IMPROVEMENTS IN MACHINERY
FOR SPINNING, DOUBLING, TWISTING, OR WINDING WOOL, WORSTED, COTTON, OR
OTHER FIBROUS SUBSTANCES.
According to our Invention the spindles and flyers are mounted in separate rails,
so as to revolve independently of one another, the flyer being driven by means of a
band passing round a pulley formed on the boss thereof, and the spindles following
it at a slower speed according to the amount of tension or drag which is put upon
the yarn. This drag or tension is regulated by means of a lever hinged to the
frame, and carrying a friction pulley, which bears against the spindle with more or
less pressure according to the material under operation, the pressure being regulated
by a weight which is adjustable upon the lever at different distances from the
fulcrum.
We may employ solid spindles, but prefer to employ spindles formed of metal
tubing in the largest part, and solid at each end, which possess the required strength,
and are much lighter. By our improvement we are enabled to use bobbins either
fast or loose upon the spindles, and the drag can be regulated with case and
accuracy. We are also enabled to wind condenser threads without twisting them,
or we can put in as much or as little twist as is desirable, especially when the said
condenser threads have a small spun thread in the centre thereof.

JOHN TODD NEWSOME, of the Firm of M. Newsome, Sons, and Speddings, of Dews-
bury, in the County of York, Manufacturers, and JOSEPH HENRY ROBERTSHAW, of
Ravensthorpe; in the said County, Overlooker. "IMPROVEMENTS IN MACHINERY
FOR SPINNING, TWISTING, DOUBLING, OR WINDING WOOL, WORSTED, COTTON, OR
OTHER FIBROUS SUBSTANCES."
According to our Invention the spindles and flyers are mounted in separate rails,
so as to revolve independantly of one another, the flyer being driven by means of a
band passing round a pulley formed on the boss thereof, and the spindle following
it at a reduced speed according to the amount of tension or drag which is put upon
the yarn. This drag or tension is regulated by means of apparatus for producing
friction, the amount thereof being regulated by an adjustable weight.
We may employ solid spindles or spindles formed of metal tubing in the largest
part, and solid at each end, which possess sufficient strength, and are much lighter.
The bobbins may be either fast or loose upon the spindles, and by the use of our
improvements the drag can be regulated with each and accuracy. Condenser
threads may be wound and the twist varied according to requirement. Our machine.
is well adapted for winding condenser threads having a fine spun thread in tho
centre thereof.
In order that our Invention may be more fully understood, we herein give
reference to the accompanying Sheet of Drawings illustrative thereof.
Fig. 1 is side elevation of spinning apparatus, partly in section; and Fig. 2 is
front elevation of same. Figs. 3, 4, and 5 are details drawn full size of parts con-
tained in the general views. A are the spindles, which are constructed of steel
tubing in the largest part, the foot and neck or upper portion being solid (or
spindles entirely solid may be used instead); B are the bobbins, which may be
either fast or loose upon the spindles. The flyers C are mounted in a fixed rail D,
and have a long collar d through which the spindle passes. The hole through the
collar is larger in diameter than the spindle, and is provided with a small bush cat
the top, which fits around the spindle and steadies it without much friction. E are
the rovings or condenser threads which are wound upon the bobbins F in the usual
manner, and delivered therefrom by the surface drum G. The roving passes between
the rollers H, through the twisting tube J, which puts in sufficient twist to enable
the yarn to be drawn out by passing between other rollers K, which revolve faster
than the-roller H, from whence it passes through the guide board L to the flyer and
bobbin or spool B.
The roving is wound upon the bobbin, and receives more or less twist during the
process according to the speed of the flyer, and the speed of the spindles is regulated
by means of the brake M, which is a grooved pulley carried on the end of a lever M',
mounted on a fulcrum m, and having a balance weight n, which presses the pulley
against the spindle with a force varying according to its position upon the lever.
For steadying the spindles and preventing the break M from pressing them to
heavily against the bush c placed within the long collar d, we employ a small tube p,
adjustable in fixing 8, attached to the rail D. In Fig. 5 we have shewn a section of
hollow spindle, and a form of brake slightly different from that just described, the
pulley being replaced by a short tube S of metal fitting over the spindle, and
attached to the end of the lever M'; the grooved pulley being employed in making
warp," and the tube when making "weft."
For stopping the flyers we employ a forked brake N, having a flat end O, pushing
which, say, with the operators knee, the fork is caused to clip around the collar of

page_text: "joining
the flyer, causing the same to stop, and leaving both hands at liberty for "
ends or other purposes.
"
This brake is shewn in plan view in Fig. 4.
Having thus described the nature of our Invention, and the manner in which the
same is to be carried into practice, we would have it understood that we do not
confine ourselves to the precise details of construction or arrangement, as the same
may be varied without departing from the peculiar features of the Invention, but
what we do claim as our Invention is,-
Firstly. The use and employment of the brakes M and S for applying friction to
the spindles for retarding the revolution of same, in mannor substantially as herein
shewn and described.
Secondly. The general combination and arrangement of the parts constituting
our improved machine, substantially as and for the purpose herein shewn and
described.
In witness whereof, we, the said John Todd Newsome and Joseph Henry
Robertshaw, have hereunto set our hands and seals, this Fourteenth day of
August, in the year of our Lord One thousand eight hundred and seventy
nine.
Witness to the signing
hereof by
ROBT. SPEDDING.
