GEORGE HOWARTH, Overlooker, and WILLIAM COWBOURN, Mechanic, both of
Bradford, in the County of York. "IMPROVEMENTS IN APPARATUS EMPLOYED
IN SPINNING AND TWISTING WORSTED AND OTHER YARNS."
Our Invention relates to improvements in spinning apparatus, whereby we
prevent the forming of "hard waste" or doubling with the yarn of a neighbouring
spindle and also stop snarls, and convey the draughted roving to the front rollers
to be there rolled and formed into roller laps during the time the operator is
occupied elsewhere.
We also employ flyers made with conical, round, or circular bosses to steady the
flyers and to prevent loose or broken yarns getting entangled on the tops of the
flyers.
For this purpose, and to prevent snarls or doubles, we employ guards made of
thin plates of metal and with sharply curved dropping plates. The guards project
from the front of the top board, and are made plain, without slits or openings, and
instead of being of the ordinary form they are made nearly the shape of a heart.
On the slackness or breakage of a thread such thread slides down the sharply
dropping curved plate and comes in contact with the shoulder of the flyer, thus
preventing the thread from running into the other threads in the process of
spinning, and from forming bottom doubles.
And to prevent top doubles and snarls we fit on the top of the top board rail
also guards, which are by preferonce made of a crescent shape. The guard is cut
inside with teeth, and the bottom part is flat and also cut with teeth, and the
crescent top is made with a foot plate and cut with a slot hole to allow of placing
the guard to the required position and of fixing it (thereto. The crescent shaped
guard is placed near to and in front of the front rollers and in such a position that
the thread when in the process of spinning passes freely through the crescent; but
should a thread become slack or broken the same would fall and come in contact
with the teeth either at the bottom or on the sides, and be retained therein until
taken up by the rollers to form roller laps. The guards can be made in segments
or in lengths, and in doffing, to remove the bobbin, we employ stops to prevent
the top board coming in contact with the guard,

page_text: Our flyers are made with bosses, which project over the shoulders of the flyers,
and have the tops of the bosses level with the tops of the spindles. The boss of
each flyer is also made projecting under the shoulders of the flyer, and is made by
preference of a conical shape, and the bosses are so made that they balance the
flyers, which allows of running at an increased speed.
We also make the boss of our flyers with a ball having a hole drilled therein,
and cut with a thread to receive the spindle top.
And for flyers hitherto in use we fit on the top of the socket a conical ring or a
cap made straight with rounded ends. The top of the ring or cap is made flat;
the ring or cap is made to be level with the spindle top.
