the said James Compstone Fell in the Great Seal Patent Office on the 12th
October 1880.
JAMES COMPSTONE FELL, of Ashton under Lyne, in the County of Lancaster,
Machinist. "IMPROVEMENTS IN MACHINERY OR APPARATUS FOR SPINNING AND
DOUBLING COTTON AND OTHER FIBROUS MATERIALS."
This Invention relates to that class of spinning machinery in which a fixed tube
or collar is provided as a bearing for the upper part of the spindle, and consists in
adapting to such fixed tube a bobbin carrier, which, while it admits of the facile
doffing of the bobbin, will hold it steadily in place, thereby giving a more regular
and even drag with a minimum of friction.
This improved carrier I form of solid metal, made preferably out of steel tubing,
bored or otherwise made to fit freely but concentrically upon the fixed tube, and by
this method of constructing the carrier the spindle is capable of being driven at a
much higher rate of speed than has been possible hitherto without unduly straining
the material which is being spun or doubled.
This carrier being made to run truly upon the tube puts a perfectly even drag
upon the bobbin, and ensures greater regularity in the stretch of the yarn.
To provide for the adaptation of this carrier to the fixed tube and to secure it
from being drawn off with the bobbin in the act of doffing I form a groove in the
upper end of the fixed tube, into which groove I lay or fit a piece of wire or metal,
or its equivalent, of such thickness as to project slightly beyond the periphery of
the tube, and I fasten the same in place by brazing or other means after the carrier.
has been fitted on the tube. The upper edge of the carrier, which is bevilled to
admit of the more easy application thereto of the bobbin, will strike the projecting
edge of the fixed piece of metal or its equivalent, when the doffing of the bobbin
takes place, and the carrier will be left on the tube.
This arrangement allows of the rapid and easy lifting of the carrier when
necessary for cleaning and other purposes. To allow of the oil for lubricating the
spindle passing freely to the inner periphery of the carrier holes may be provided
in the lower part of the tube or collar, which may be grooved on its periphery.
at this part, the better to retain the oil in place, and to diminish the wearing
surface.
*31 4.
In order to provide a durable and easily renewable wearing surface for the carrier
to work upon a short piece of metal tubing, preferably steel, may be shrunk on
or otherwise secured to the lower part of the tube or collar, and the same result
may be attained by the use of flat steel wires brazed or otherwise firmly fixed
into grooves formed for that purpose in the lower part of the tube or collar.
In the accompanying Drawing Fig. 1 shews in elevation a throstle spindle
and flyer with my improvements applied thereto, and Fig. 2 is a sectional view of
the fixed tube with the spindle in place, the bobbin carrier being also in section,
and the bobbin being raised as in the act of doffing, the flyer being removed for
that purpose.
A is the spindle which is supported in a footstep as usual, and runs in a tube B
made fast in the lifting rail C. The bobbin carrier tits freely on this tube B and
rests on the flange b, and it is retained in place by a piece of wire or metal b¹
brazed or otherwise fastened in an annular recess turned in the
upper end
of the tube B. The peculiar construction of the improved carrier will be best
understood by reference to the detached views, Figures 3 and 4, which represent
it as a short tube accurately bored on its inner periphery, and by preference slightly
tapered on its outer periphery to allow of the bobbin fitting snugly thereon, its
upper edge being chamfered off to enable it to enter readily the barrel of the

page_text: bobbin, and thereby form a metallic bearing for the same. The upper end of the
barrel of the bobbin is bushed or otherwise made to fit the spindle in the usual
manner, and the bottom of the bobbin rests and runs either on the bare spindle
rail, or preferably on a strip of wood placed on such rail. Upon the doffing of the
bobbin the carrier E will be caught by the underside of the fixed piece of metal b',
and will thus be held back while the bobbin is being removed by the attendant, as
indicated at Fig. 2.
An obvious modification of the carrier above described is to form it of solid
metal cast with a tray or saucer round its base; and to diminish what small amount
of friction there may be when running a circular rim or boss is preferably formed
on the underside of the tray of the carrier, the drag being regulated by a band or
washer of felt or in any other convenient manner.
This form of carrier is shewn detached at Figures 5 and 6 of the Drawings, and
in position at Figures 7 and 8. Fig. 7 also shews the arrangement of an inner
steel or metal tube shrunk on or tightly fixed to the tube or collar for the
purpose of providing a durable and easily renewable wearing surface for the carrier
to work upon.
Another method of attaining the same result is shewn at Fig. 8, and consists in
simply grooving the lower part of the fixed tube or collar, and brazing or otherwise
firmly securing in the grooves thus formed flat steel wires which, when in place,
will project slightly beyond the periphery of the fixed tube.
I would remark that either form of the improved carrier may be adapted to the
fixed tube in various ways, such as making the tube in two parts which may be
brazed together or otherwise firmly connected after the carrier has been applied
thereto, and in this case it will be possible to substitute for the piece of wire or
metal which is brazed in the top of the grooved tube, a solid head or its equivalent
for retaining the carrier on the tube.
The Invention can be readily applied to any throstle or similarly constructed
machine, or to a doubling frame or other machines where spindles and flyers are
used, and this without any material alteration in the diameter of the bobbin used,
or any material increase in the lift of the machine.
Having now set forth the nature of my Invention of " Improvements in
Machinery or Apparatus for Spinning and Doubling Cotton and other Fibrous
Materials," and explained the manner of carrying the same into effect, I wish
it to be understood that under the above in part recited Letters Patent I claim,―
Fitting to a fixed tube, such as B, in which a spindle rotates, a solid metal
carrier constructed as above explained, such carrier being retained upon the tube
by a piece of wire or metal brazed or otherwise fastened in a groove turned in the
fixed tube, or by equivalent means, for the purpose and in the manner substantially
above set forth.
In witness whereof, I, the said James Compstone Fell, have hereunto set my
hand and seal, the First day of October, in the year of our Lord One
thousand eight hundred and eighty.
