PROVISIONAL SPECIFICATION left by the said James McGregor at the Office
of the Commissioners of Patents on the 17th August 1882.
JAMES MCGREGOR of Queens Road Manchester in the County of Lancaster.
IMPROVEMENTS IN RING SPINNING AND DOUBLING MACHINERY
One portion of my invention relates to the Rings usually used for Spinning and
which are fixed into what is known as the ring rail: these rings which are
tubular have formed upon one or both ends a T shaped flange upon which a
traveller slides: these flanges have hitherto been made to lie at right angles to the
axis of the tubular rings but which I propose to construct with these flanges lying
at an angle inwards and downwards for the purpose of equalizing the wear between
the inner and outer webs of the flange and also of the feet of the traveller which
slides along them: I also prefer to make the inner edge of the Hange thicker than
the outer one for the purpose of securing greater wearing surface on the inner edge
of the flange The same object may be attained, in a different way, by inclining
the angle of the flange outwards instead of inwards
Another class of tubular rings occupying the same relation to the ring rail but
mostly used for doubling purposes have no flanges but merely their edges rounded,
these I purpose making reversible by cutting two similar grooves on the outside
circumferentially and equidistant from each edge; an elastic metal ring is made to
6t either of the grooves and projects beyond the external surface so as to form a
shoulder resting upon the ring rail in place of the solid flange usually made upon
rings of this description and it is obvious that as the grooves are equidistant from
cach edge whichever edge of the tubular ring is uppermost it stands at equal
height above the ring rail-By the same construction I make reversible rings for
spinning purposes

page_text: Another modification of the tubular ring for doubling purposes is to form a solid
flange upon the outside of the tubular ring and in the centre of its depth and of
sufficient width to form the seat of the tubular ring, this flange fits into a
corresponding recess formed in the ring rail and is reversible under the same
conditions as previously mentioned
Another portion of my invention relates to a class of Spindles used in connection
with the above named tubular rings and which have a continuous or nearly
continuous bearing inside a metal tube & on the lower outside portion of which is
an oil reservoir communicating withe the inside of the bearing tube by means of a
hole or holes in the tube the lower part of the spindle being parallel though not
necessarily of the same diameter, this oil reservoir is usually made open at the
top and covered by a flange projecting from the spindle warve: instead of this
arrangement I construct a covered reservoir through which the spindle bearing tube
passes and is fastened at the bottom in the usual manner. At the top of the reservoir
however the tube is secured by means of a split conical bush which bush is driven
as a wedge into the hole at the top of the reservoir at the same time closely
embracing the outside of the tube, thus not only securing the tube but giving it
increased strength: I supply fresh oil or abstract dirty oil from this reservoir by
means of a hole at its top & without disturbing the spindle to avoid the oil
overflowing the top of the bearing tube I construct a small cup at its top and also
back rifle the tube a short distance from the top downwards-I also construct a
longitudinal groove along the inside of the tube to allow the oil to return to the
reservoir at the lower portion of the tube and this groove I preferentially
construct along the opposite side to that most pressed against by the action of
driving.
Another portion of my invention refers to spindles in which it may be thought
necessary to drive the bobbins direct from the sleeve and warve instead of through
the spindle. By one method I propose to extend the sleeve to the top of the
spindle and cutting a slot through both spindle and sleeve into which drops a pin
fixed across the top of the bobbin-Another method of accomplishing the same
object is by constructing two solid Lugs on the upper face of the spindle warve
these lugs I make of the thickness of the diameter of the sleeve, thus getting rid
of the necessity for driving on to the sleeve lugs of the usual construction

IMPROVEMENTS IN RING SPINNING AND DOUBLING MACHINERY
One portion of my invention relates to the rings used for "Spinning" and which
are fixed in the ring rail.-these rings have formed upon one or both ends a
T shaped flange upon which a traveller slides of the construction shewn in
connection with the rings on the accompanying sheet of drawings. It has been
found in practice that only the inner foot of the traveller comes in contact with
the under side and edge of the inner flange when at work, and this portion of my
invention causes the rings and travellers to be in contact in at least two points
simultaneously, thus distributing the friction and consequent wear and tear. One
method by which I accomplish this object is effected by raising the outside edge of
the flange so that it comes in contact with. the bow of the traveller: another
method is to construct the underside of the outer flange below the level of the
underside of the inner flange so as to engage with the foot of the traveller on the
outside of the ring; and a third modification is to construct a ledge or shoulder on
the outside of the ring so that the outer foot of the traveller may slide upon it.―
Fig 1 and 2 in accompanying sheet of drawings shew the position the travellers
assuine when at work upon rings ordinarily in use. Figs. 3. 4 & 5 represent my
improved rings relatively as herein described.
Another portion of my invention relates to another class of rings, occupying the
same relative position to the ring rail, used for " Doubling" purposes-these I make
reversible by cutting two similar grooves on the outside circumferentially and
equidistant from each edge; an elastic metal ring is made to fit either of the
grooves and project beyond the external surface so as to form a shoulder resting
upon the ring rail. Fig: 6 represents this ring part of which is broken away to
shew it both sectionally and in elevation A, A, are the grooves and B. B the clastic
ring referred to.-Another method of accomplishing the same object is to form a solid
flange upon the outside of the ring in the centre of its depth of sufficient width to
form the seat of the ring, this flange fits into a corresponding recess formed in the
ring rail Fig 7 is a drawing in elevation of this ring. A being the flange
referred to
By similar means I make "spinning" rings reversible also
A further portion of my invention relates to a class of spindles used in connection
with the above named rings and which have a continuous or nearly continuous
bearing inside a metal tube on the lower outside portion of which is an oil reservoir
communicating with the inside of the bearing tube by means of a hole or holes in
the tube: the lower portion of the spindle being parallel though not necessarily of
the same diameter this oil reservoir is usually made open at the top and covered
by a flange projecting from the spindle warve. My invention consists in
constructing a covered reservoir through which the spindles bearing tube passes and
is fastened at the bottom in the usual manner, at the top of this reservoir the
tube is secured by means of a split conical bush driven as a wedge into the hole at
the top of the reservoir and closely embracing the outside of the tube thereby
rigidly fixing the same and gaining increased strength-fresh oil is supplied or
dirty abstracted from this reservoir by means of a hole at its top as shewn on
accompanying drawing.-to avoid the oil overflowing at the top of the bearing
tube I construct a small cup and also back rifle the tube a short distance from
the top downwards, I also construct a longitudinal groove along the inside of the

page_text: tube communicating from the upper to the lower oil reservoir and which is
preferentially formed along the opposite side to that most pressed against by the
action of driving Fig. 8 is a sectional drawing of this portion of my invention-
the central portion of the spindle being broken away to shew A. The top oil cup
B the longitudinal groove. C the back rifling D the conical split bush E the hole
for supplying oil to F the covered oil reservoir referred to
Another portion of my invention refers to spindles where it may be thought
necessary to drive the bobbin direct from the sleeve and warve instead of through
the spindle This I effect by extending the sleeve to the top of the spindle and
cutting a slot through both spindle and sleeve into which drops a pin fixed across
the top of the bobbin as shewn in Fig: 9: Another method of accomplishing the
same object is by constructing two solid lugs on the upper face of the spindle
warve; these lugs I make in breadth at least the diameter of the sleeve as shewn
in Fig 10. A being one of the lugs referred to
Having described the nature of my invention and the manner of performing the
same I hereby declare that I claim the making and use of "spinning" rings used
in connection with the special class of traveller herein shewn substantially as
herein described by which the traveller is supported when at work by at least two
different portions of the ring simultaneously.
The making and use of reversible "spinning" and "doubling" rings by the two
methods berein described and shewn.
The arrangement herein set forth in connection with spindles having a
continuous or nearly continuous bearing inside a metal tube, consisting of a
covered oil reservoir, longitudinal groove along the inside of bearing tube, back
rifling of a portion at top of said tube and small oil cup at top of same; and the
method of fastening said metal bearing tube at top of covered oil reservoir by
means of a split conical bush
The construction of this class of spindle by extending the sleeve to the top of
the bobbin and cutting the slit across both spindle and sleeve
The construction of solid lugs on upper side of warve of a breadth not less than
the diameter of the sleeve
I do not confine myself that the aforesaid improvements shall be used in
connection with each other at all times but claim them individually and
seperately as by the adoption of any one of them a corresponding advantage may
be realized.
In witness whereof I the said James McGregor have hereunto set my hand
and seal this twelfth day of February in the year of our Lord, One thousand
nicht hundred and kighty three
In the presence of
