1 JAMES WATERHOUSE MIDGLEY of Park Lanc Machine Works Keighley in the
County of York Machine Maker do hereby declare the nature of this invention to be
as follows:
This invention relates firstly to a new or improved application of parts whereby the
driving cord, which transmits revolving motion to the bobbin or spool, through the
other well known parts used in connection with spinning, doubling and twisting
machinery is kept in the same plane and not allowed to rise and fall or traverse up
and down as does the said bobbin and other parts in the manner and for the purpose
well known.
To accomplish this I substitute the grooved pulley heretofore used, and which is
driven by the before named driving cord; with a plain drum (which if desired may
have a flange at or near each of its outer ends), the length of which is regulated by
And, as will
the distance required to be traversed up and down by the said bobbin.
be readily understood, by having a guide piece, such as a bar or roller, across the
machine to guide the leading side of the series of driving cords; as the bobbins are
raised and lowered the necessary raising and lowering of the said drum, without the
lifting or lowering of the driving cord, is allowed by the uniformity of its surface.
Instead of the said guide roller going the whole length of the machine and so
guiding the whole series of driving cords, each cord may be guided by a separate
roller or other guide piece as will readily be understood.
The joining of the above named plain drum to the tube (commonly used), and also
to the bobbin so as to impart revolving motion thereto, is accomplished by the use of
a pin or pins fixed into the end of the said drum (the said pins being heretofore fixed
into the end of the grooved pulley) in the usual manner with the exception that the
tube is only loosely dropped on, so as to be driven by, the pins, instead of being
rigidly attached thereto; for the purpose explained in connection with the second part
of this invention.
The second part of this invention relates to new or improved means for supplying
lubricant to the foregoing plain drum, or to the well known kind of grooved pulley.
or to other similar grooved pulleys which revolve on an upright stationary spindle, or
which revolve on an upright tube relatively at resi, as regards the upward and down-
word motion of the drum or grooved pulley.

page_text: In connection with my new or improved drum (above described) this is accomplished
by mounting a tube, corresponding in length to the said drum; upon the lifter plate
of the machine, the lower end of the said tube being suitably shaped so as to form an
appropriate receptacle for the lubricant. My new or improved drum is made to fit
over this tube, and its lower end is made of a suitable shape (being formed to slightly
taper upwards a suitable distance, which said tapering form is also given in a corres-
ponding degree to the inner surface of the receptacle at the bottom of the before
described upright tube), to fit loosely and suitably into the receptacle for the lubricant
at the bottom of the upright tube.
On the inner surface of the said drum, which is in close connection with the outer
surface of the upright tube, I form a spiral groove which extends from the bottom
upwards to within an appropriate distance of the top at which distance I form a
recess or what is commonly known as a chamber, so that as the drum revolves the
lubricant is raised by the spiral groove (on the principle of the screw of Archimedes)
into the chambered part which prevents its further ascent, and from which at every
opportunity it flows back to the receptacle at the bottom. Or I might construct the
drum with the chamber as above described but without the spiral groove, since I find
that the lubricant by the motion of the said drum with a plain inner surface is raised
into the chamber above described but not so efficiently as when the spiral groove
is used.
And to facilitate the supply of lubricant to the above I make the upper outer end
of the drum of a suitably bevelled or hollowed slape, into which by the removal of
the tube (mentioned in the first part of this description) I am able to pour the
said lubricant, which flows down to the chamber in the drum and so accomplishes
the desired object.
To accomplish the foregoing in connection with the well known grooved pulley
and stationary spindle, I form the receptacle for the lubricant in a similar manner to
the above, but attach it to, or form it on, the spindle. The internal parts of the
grooved pulley (and the usual well known tube which is rigidly attached thereto)
having the spiral groove and chambered part, or chambered part alone, formed therein
as above described.
The third part of my invention relates to the construction of the drum and the tubes
mentioned in the above description, also to the construction of similar other tubes and
caps used in this class of machinery.
"
Respecting the drum I form it of any suitable material, such as wood, metal &c.,
and insert a spirally formed wire either closely or openly folded as may be desired
and covered with any suitable meial, such as solder etc., to make its inner surface
uniform and smooth, or the same may be left uncovered so as to form the spiral
groove, being used in the manner and for the purpose above described.
Respecting the construction of the tubes and caps, I form the cylindrical portions of
them of spirally and closely folded wire over which I pour molten metal, such as solder,
etc., to make the surfaces thereof uniform and smooth.

page_text: COMPLETE SPECIFICATION,
Improvements in Spinning, Doubling, and Twisting Machinery.
I JAMES WATERHOUSE MIDGLEY of Park Lane Machine Works Keighley, Machine
Maker do hereby declare the nature of this invention and in what manner the same is
to be performed, to be particularly described and ascertained in and by the following
statement
This invention relates firstly, to a new or improved application of parts whereby the
driving-cord, which transmits revolving motion to the bobbin or spool through the
other well known parts used in connection with spinning doubling and twisting
machinery; is kept in the same plane and not allowed to rise and fall or traverse up
and down as does the said bobbin and other parts in the manner and for the purpose
well understood.
In order that the said invention may be more readily understood I have hereunto
appended a sheet of drawings illustrative thereof, wherein figs. 1 and 2 are sectional
side elevations shewing the bobbin or spool in its lowest and highest positions respec-
tively only such portions of the machine being shewn as are necessary to illustrate
same, the other portions not shewn, being of the common well known kind. Figs. 3.
4. 5. 6 and 7 are sectional detail drawings, enlarged scale, of parts hereinafter
referred to.
The object above set forth is accomplished by substituting the grooved pulley or
"wharle heretofore used and which is driven by the before named driving cord;
with a plain drum a, (which if desired may or may not, have a flange at or near each
of its outer ends) the length of which is regulated by the distance required to be moved
or traversed" up and down by the bobbin b. And, as will be readily understood, by
having a guide piece such as a bar or roller across the machine to guide the leading
sides of the series of driving cords as the bobbins are raised and lowered the
necessary raising and lowering of the said drums a, without the lifting or lowering of
the cords d, is allowed by the uniformity of the surface of said drum a.
Instead of the guide roller going the whole length of the machine and so
guiding the whole series of driving cords d, each cord may be guided by a separate
roller or other guide piece as will readily be understood.
The joining of the above named drum a to the tube e (commonly used), and also
to the bobbin so as to impart revolving motion thereto, is accomplished by the use
of a pin or pins fixed to the drum a (similar pins being heretofore fixed into the
end of the grooved pulley) in the usual manner, with the exception that the tube e
is preferably only loosely dropped on, so as to be driven by the pins f instead of
being rigidly attached thereto; for the purpose explained in connection with the
second part of this invention, however to give greater stability to the said tube e
when so used, its lower end is made to enter the end of the drum a as shewn
by fig. 3.

page_text: The second part of this invention relates to new or improved means for supplying
lubricant to the above described drum «, or to the well known kind of grooved
pulley or to other similar grooved pulleys which revolve on an upright stationary
spindle, or which revolve on an upright tube relatively at rest as regards the upward
and downward motion of the drun or grooved pulley.
In connection with my new or improved drum a (above described) this is accom-
plished by mounting a tube g (see fig. 5), corresponding in length to the said drum a
upon the lifter plate of the machine, the lower end of the said tube being
suitably shaped so as to form an appropriate receptacle for the lubricant. The drum
is made to fit over this tube g, and its lower end is made of a suitable shape (being
formed to slightly taper upwards a suitable distance, which said tapering form is also
given in a corresponding degree to the inner surface of the receptacle at the bottom of
the tube g), to fit loosely in the receptacle at the bottom of the tube.
On the inner surface of the drum a, which is in close connection with the outer surface of
the tube g, I form a spiral groove which extends from the bottom upwards to within an
appropriate distance of the top (see fig. 6) at which distance I form a recess or what is
commonly known as a chamber i (fig. 6) so that as the drum a revolves, the lubricant
is raised by the spiral groove (on the principle of the Archimedian screw) into the
chambered part which prevents its further ascent, and from which at every oppor-
tunity, as when the drum a is stationary, it flows back to the receptacle at the bottom.
Or I might construct the drum a with the chamber as above described but without
the spiral groove, since I find that the lubricant by the motion of the said drum a with
a plain inner surface is raised into the chamber i but not so efficiently as when the
spiral groove is used.
And to facilitate the supplying of lubricant to the above I make the upper outer end
of the drum a of a suitably bevilled or hollowed shape. (figs. 5 and 6) into which by
the removal of the tube e (mentioned in the first part of this description) I am able
pour the said lubricant which flows down to the chamber and so accomplishes the
object desired.
to
To accomplish the foregoing in connection with the well known grooved pulley
which has no upward and downward movement imparted to it (the said movement
being imparted to the bobbin through the upward wires or rods o) and stationary
spindle (see fig. 7) I form the receptacle for the lubricant in a similar manner to the
above, but attach it to or form it on the spindle . The internal parts of the grooved
pulley or "wharle having the spiral groove and chambered part, or chambered
part alone, formed therein as above described.
2:
The third part of this invention relates to the construction of the drum a and the
tube e mentioned in the above description, also to the construction of similar other
tubes and the "caps" m used in this class of machinery..
Respecting the drum a I form it of any suitable material such as wood, metal etc.,
and insert a spirally formed wire n (which may be either of round, flat or other shape)
either closely or openly folded (see fig. 6) as may be desired, thus forming the groove,
the same being used in the manner and for the purpose above described. Or again if,
by forming the said drum a solid as above described, it is thought to be too heavy I
might make it hollow as shewn by fig. 4.
Respecting the construction of the tubes e and caps m, I form the cylindrical
portions of them, of spirally and closely folded wire (which may be either of round
or other shape) over which I pour molten metal such as solder etc., or place thereon
sheet metal as iron, steel or brass, or place the said spirally formed wire within a solid
drawn metal tube to make the outer surfaces thereof uniform and smooth.
The said outer shell may or may not be of hardened metal as is desired.
Having now particularly described and ascertained the nature of my said Invention,
and in what manner the same is to be performed, I declare that what I claim is:
1. The use or employment of the drum a substantially in the manner and for the
purposes herein specified.

page_text: 2. The use or employment of the drum a in combination with the guide piece or
pieces e in the manner and for the purposes fully set forth.
3. The several methods herein described of constructing the drum a to the end
set forth.
4. The means employed for supplying lubricant to the parts herein described
substantially as specified.
5. The construction of the tubes e with an inner and outer shell substantially as
specified.
