Hull in the County of York for an Invention of IMPROVEMENTS IN COLLARS
FOR SPINNING & DOUBLING
PROVISIONAL SPECIFICATION left by the said William Jackson at the
Office of the Commissioners of Patents on the 16th April 1883.
WILLIAM JACKSON of the Borough of Kingston upon Hull in the County of
York "IMPROVEMENTS IN COLLARS FOR SPINNING AND DOUBLING."
The object of my Invention is to provide a Collar bearing for the spindles of
Flyer frames used for Spinning Doubling and Twisting purposes of such a character
that the bearing of the spindle in the collar without being of undue length and
height to give steadiness to the spindle when revolving with a high velocity and
shall at the same time ensure a proper system of lubrication not only as between
the spindle and the collar but also between the Collar and the bobbin without
which the drag upon the bobbin is subjected to great variations causing con-
siderable waste-and-in the case of Doubling and Twisting-Frames-oftentimes
troublesome irregularities in the quantity of Twists or turns per inch of the yarn.
My Invention is substantially carried into effect by providing a collar of, Cast
Iron, Steel or other suitable metal, at the upper end of which is inserted a ferule of
brass which forms the top bearing of the spindle, Through the lower portion of
this ferule of brass are pierced holes, with corresponding holes through the Iron or
Steel portion of the collar: these holes are covered externally by a helical hoop,
made of brass wire, which when in use revolves, with the Bobbin loosely upon that
part of the Cast iron or steel portion of the collar which lies immediately over or
upon the upper Spindle rail into which the collar may be secured either by a screw
thread or when more convenient by a Nut or Nuts on the lower side of the
Spindle rail
The Helical hoop of brass wire is provided for the purpose of conveying when
revolving with the Bobbin the necessary oil for the lubrication of itself-the
bobbin and the spindle within the Collar-bearing, The oil-whenever a supply

page_text: becomes necessary is supplied to and held-when the spindle is not working—
within a circular Groove or Cavity formed in that portion of the base of the Collar
which lies immediately upon the Spindle rail
When the Helical Hoop revolves the oil in the circular cavity mounts upwards—
owing to the inertia of its particles-as by a screw thread. The lower portion of
the Bobbin revolving on the Helical hoop takes off from the Hoop a sufficient
quantity of oil for its own lubrication while the oil for that portion of the spindle
revolving within the collar is supplied by the Hoop and delivered through the
small holes pierced-through the Collar with its brass ferule to the spindle
By this means a high velocity of Spindle can be maintained and that great
uniformity of drag upon the Bobbin secured which is so essential to excellence in
the manufacture of all kinds of Thread

WILLIAM JACKSON of the borough of Kingston-upon-Hull in the County of
York IMPROVEMENTS IN COLLARS FOR SPINNING AND DOUBLING
My Invention consists of certain "Improvements in Collars for spinning Doubling
and Twisting frames."
Whereby a proper system of lubrication is ensured not only as between the
spindle and the collar, but also, between the Collar and the Bobbin, without which
the drag upon the bobbin is subjected to great variations, causing considerablo
waste and in the case of doubling and Twisting Frames often-times troublesome
irregularities in the quantity of Twists or turns per inch of the yarn.
Herewith I attach a sheet of drawings bearing a sectional view of my invention
on an ordinary spindle.
.A. A. is an ordinary spindle, .B. B. an ordinary bobbin. .C. C. C. C is a collar
made of cast iron, steel. or any other suitable metal, d. d. is a ferule of brass or
other suitable metal which forms the top bearing of the spindle, .e. in the lower
end of this bush and that portion of the collar represent two holes opposite each
other, these holes are covered externally by a helical hoop .f. f. f. f. made of. brass-
steel. or any other kind of metal, This helical hoop revolves with the Bobbin
loosely upon that part of the collar. which lies immediately over or upon the upper
spindle rail. .D. into which the collar may be secured either by a screw thread or
when more convenient by a nut or nuts on the lower side of spindle rail.
The helical hoop .f. of metal wire is provided for the purpose of conveying when
revolving with the bobbin. B. The necessary oil for the lubrication of itself the
bobbin B. and the spindle. A. within the collar bearing. The oil whenever a
supply becomes necessary is supplied to—and held when the spindle is not working.
within a circular groove or cavity formed in that portion of the base of the collar
marked .h. h. which lies immediately on the spindle rail.
When the Helical Hoop revolves the oil in the circular cavity mounts upwards—
owing to the inertia of its particles as by a screw thread, The lower portion of
the Bobbin revolving on the Helical hoop takes off from the Hoop a sufficient
quantity of oil for its own lubrication, while the oil for that portion of the spindle
revolving within the collar is supplied by the hoop and delivered through the small
holes .e. pierced through the collar with its brass ferule .d. to the spindle .A..
By this means a high velocity of spindle can be maintained and that great
uniformity of drag upon the bobbin secured which is so essential to excellence in
the manufacture of all kinds of threads.
The great advantage to be derived from the use of my improved collar is mainly
in the system of lubrication which has been the great defect of former systems.
By my system the oil is applied to and carried upward by the Helical carrier
from the dish or basin h. h. at the bottom immediately under the bobbin. and
supplied in requisite quantity through the holes .e. to the spindle and between the
several coils to lubricate the collar and the bobbin.
By the old system the oil is supplied at the top of the bobbin and descends by
gravitation, This oil is frequently scattered by the motion of the spindle and
carried by the flange of the bobbin on to the yarn during spinning or. Winding,
What oil descends by gravitation is largely wasted having no basin or dish to
receive it.
Having described my invention and the way which I apply the same I wish it
to be distinctly understood that I do not confine myself to the precise details

page_text: I have had occasion to describe or refer to. as many variations may be made in
detail without deviating from the principle but what I claim as secured to me
herein is,
First the Collar .C. Substantialy as and for the purposes herein before set forth,
Second. the Helical Hoop f. Substantialy as and for the purposes herein before
set forth.,
Third and last the combination of the several parts hereinbefore named Substan-
tialy as and for the purposes hereinbefore set forth,
