WILLIAM SUMNER, of Preston, in the County of Lancaster, Spindle and Fly
Manufacturer. "IMPROVEMENTS IN MACHINERY USED FOR PREPARING, SPINNING,
DOUBLING, TWINING, AND WINDING COTTON, WOOL, FLAX, SILK, OR OTHER FIBROUS
MATERIALS OR SUBSTANCES."
My Invention consists,-
First. In hardening, slubbing, intermediate, and roving frame spindles at the
traverse or collar part of the spindle.
Secondly. In an improved mode of hardening and tempering throstle, doubler,
ring, twiner, and mule spindles at the collar and blade part, whereby I am enabled
to procure a much stiffer spindle which will not wear or go crooked like a spindle
not similarly hardened. This hardening I accomplish by heating the part of the
spindle to be hardened, and causing it to revolve in centres, the spindle is then
made to descend through swages, rollers, or dies, to keep it true into a cooling
liquid or hardening solution. This mode of hardening spindles is applicable to the
first part of my Invention.
Thirdly. In improved modes of making doubler and throstle spinning flys or
flyers, so that the bobbin head however bad cannot injure or interfere with the drag
of the yarn or thread. I make new flyers with an eyelet hole or yarn guide at or
near each bow of the leg. To existing flyers I attach eyelet holes or yarn guides
to near the bow of the legs by brazing, soldering, or other means.
Fourthly. In improved modes of producing the drag on the spinning or doubling
apparatus known as the inverted flyer. This I accomplish as follows:-From tho
lifting rail I carry a stationary spindle up and through the stationary rail and the
driving apparatus; on the stationary spindle I fix a large flange, the rim of which I
turn with a groove at its edge, within which groove I affix a band or ring of india-
rubber, flannel, or other frictional material for the bobbin to rest upon.
Fifthly. In making spindle collars for throstle, doubler, and ring frames as
follows: That part of the ordinary short or long collar which sits upon the frame
rail, I make much larger in diameter than usual, and groove or arrange the edge of
the rim to contain a friction band as before described.
Sixthly. In making a making a machine or spindle and apparatus with or without
a flyer to work on the throstle, ring, and doubler drag principle, so as not only to

page_text: be able to spin and double yarns on bobbins, but also to spin and double cops which
may be dóffed from the apparatus upon which they are spun. Near the top of the
spindle (which is taper upwards like a mule spindle blade) I turn a recess, in which
fits a loose shell or boss, from or above which loose boss downwards I carry a very
thin steel drag shell or apparatus upon which the cop or bobbin is spun or doubled,
or the upper end of the drag shell may be made to fit the recess near the top of the
spindle the drag is obtained in the manner above described.
Seventhly. In making long or short collars for doubler and throstle frames
smaller in diameter and less liable to be broken than the cast-iron collars hitherto
employed; I make that part of the long collar which fits in the frame rail, also the
flange which fits upon the frame rail with a wrought-iron or brass tube to act as
collar; the top end of a wrought-iron tube I bush with brass; upon the upper end
of this collar is a loose shell, and below or near the flange is another loose shell to
reduce the friction; these shells fit in recesses, and the bobbins fit on the shells
without touching the collar.
