Silk Manufacturer, for the Invention of "IMPROVEMENTS IN MACHINERY FOR
SPINNING, RE-DOUBLING, AND TWISTING SILK AND OTHER YARN."
PROVISIONAL SPECIFICATION left by. the said William Stannard at the
Office of the Commissioners of Patents on the 15th May 1878.

WILLIAM STANNARD, of Leek, in the County of Stafford, Silk_Manufacturer.
"IMPROVEMENTS IN MACHINERY FOR SPINNING, RE-DOUBLING, AND TWISTING SILK
AND OTHER YARN."
My Invention consists of improved machinery for performing the various
operations of spinning, re-doubling, and twisting, and whereby absolute uniformity
in the spinning and equality in the size or thickness of the thread or yarn is
obtained.
The machinery consists of any convenient number of bobbins in sets of two or
.more for spinning. In operating upon machine silk I employ sets of three bobbins
each bobbin is driven by a band as usual, but the band passes round the wharves
of three spindles; to each wharve is fixed a pinion gearing into a centre wheel
fixed to an upright axle. At the top of each spindle is a pinion (which answers
for the ordinary mill lead) gearing into a centre wheel loose on the top of the
upright axle. By this means the three strands are made uniform in spin and in
thickness..
=
The sets of three bobbins above described are placed near the floor, as in ordinary
silk mills, and the three strands are re-doubled or run together on a bobbin or shaft
placed in the same position as in ordinary mills, but at a greater elevation, to
- ensure sufficient length.for equalizing the thickness.

The re-doubled. bobbins are, then placed on single spindles, the silk passing
through a guide above the bobbin, and then run on a reel above, as in ordinary
(silk: mills:

SPECIFICATION in pursuance of the conditions of the Letters Patent filed by
the said William Stannard in the Great Seal Patent Office on the 14th
November 1878.
WILLIAM STANNARD, of Leek, in the County of Stafford, Silk Manufacturer.
"IMPROVEMENTS IN MACHINERY FOR SPINNING, RE-DOUBLING, AND TWISTING SILK
AND OTHER YARN."
My Invention consists of improved machinery for performing the various
operations of spinning, re-doubling, and twisting, whereby obsolute uniformity in
the spinning and equality in the size or thickness of the thread or yarn is
obtained.
And in order that my Invention may be fully understood, and readily carried
into operation, I will proceed to describe the accompanying Sheet of Drawings.
Fig. 1 is a front view; Fig. 2, an end view; and Fig. 3, a plan of my improved
machinery for spinning, re-doubling, and twisting silk and other yarn.
This machine is particularly adapted for manufacturing what is known in the
trade as "machine silk."
a and b are the end frames, and c is the intermediate frame, which are connected
by suitable cross beams, stays, and roller beams; d is the driving shaft, on which
is fixed the drum d'; e is a horizontal shaft at the top of the frame, which is
driven by the train of pinions and wheels shewn by dotted circles in Fig. 2. To
the bottom cross beam f are fixed the spindles for the bobbins containing the silk
to be operated upon; these bobbins are made in sets of three, as shewn on an
enlarged scale in Figs. 4 and 5; g, g, g, are the three dead spindles ;- and is the
wharve fitting on each. On a tube attached to the wharve is placed the bobbin i.
At the under side of the wharve is fixed a spur pinion h¹. The wharves are driven
by a band or bands from the drum d, as shewn in Fig. 3. The three pinions /¹
gear into a centre wheel j¹ on the upright axle j, which is fixed in the beam f; at
the top of cach spindle g is a pinion g (which answers for the ordinary mill lead);
the three pinions g₁ gear into the centre wheel loose on the top of the upright
axle j. To cach pinion g¹ is fixed a flyer leg g³ and thread guide g³.
The yarns from each set of three bobbins are carried upwards over pulleys on
the guide rod k, and run together around the rollers and m, and then after passing
over pulleys on the guide rod they descend to the bobbins n; on which they are
wound by a flyer in the ordinary manner.
The bobbins are placed near the floor, as in ordinary silk mills, and the three
strands from each set of three bobbins after passing separately over the pulleys on
the guide rod are united before they are taken round the rollers or m. At the
front and back of each roller is placed a guide pulley, as shewn in Fig. 3. The
distance between the bobbins i and the guide rod k is sufficiently great to insure
perfect equality in the thickness of each strand.
The machinery for winding the three-fold yarn after it has been spun, re-doubled,
and twisted in the manner described on to the bobbins n, forms no part of my
Invention.
The bobbins of re-doubled yarn n are then placed on single spindles, the yarn
passing through a guide above the bobbin, then run on a reel above, as in ordinary
silk mills.
Having thus stated the nature of my Invention, and described the manner of
performing the same, I declare that I claim, -
First. The general combination and arrangement of the parts forming an im-
proved machine for spinning, re-doubling, and twisting silk and other yarn, as
shewn and described.
Secondly. The improved mode of driving two or more bobbins by one or more

page_text: driving bands, and connecting the wharves and the bobbins by gearing to ensure
equality of twist, as shewn and described in reference to Figs 4 and 5.
In witness whereof, I, the said William Stannard, have hereunto set my
hand and seal, this Eleventh day of November, One thousand eight hundred
and seventy-eight.
WILLIAM STANNARD. (L.S.)
