IMPROVEMENTS IN MACHINERY FOR SPINNING AND DOUBLING
Year: 1880

page_text: LETTERS PATENT to Benjamin Alfred Dobson, of the Firm of Messieurs
Dobson and Barlow, of Bolton, in the County of Lancaster, Machine Maker,
and Robert Crompton Tonge, of the same Place, Engineer, for an Invention of
PROVISIONAL SPECIFICATION left by the said Benjamin Alfred Dobson
and Robert Crompton Tonge at the Office of the Commissioners of Patents on
the 3rd December 1880.
BENJAMIN ALFRED DOBSON, of the Firm of Messieurs Dobson and Barlow, of
Bolton, in the County of Lancaster, Machine Maker, and ROBERT CROMPTON
TONGE, of the same Place, Engineer. "IMPROVEMENTS IN MACHINERY FOR
SPINNING AND DOUBLING."
The first part of our Invention refers to the governor motion for automatically
regulating the winding on of a self acting mule or twiner during the formation of
a cop bottom, and consists in a method of regulating the connection between the
usual endless band and the faller.
The object of our Invention is to arrest the motion of the band connected with
the quadrant by an arrangement of mechanism which can be engaged and
disengaged by the rise or fall of the counter faller by an apparatus which is
weighted very lightly, for which purposes we apply the usual governor horns
mounted upon the copping fallers and counter fallers; to these horns is attached
one end of an L shaped lever by means of a chain and pulley. The L lever is
mounted upon the carriage square by a stud; upon the other end of the L lever is
fixed a toothed shaped finger; when the counter faller is lowered by the yarn being
wound on too rapidly, the end of the L lever connected to the fallers is lowered,
which allows the other end of the L lever to come in contact with a half clutch
box. This half clutch box is mounted upon a stud and bracket, which is secured to
the carriage square. This half clutch box is arranged with two V shaped or round
grooves and with the use of an angular carrier pulley. An endless band is allowed
to pass around the said half clutch box and carrier pulley to the quadrant. When
the counter faller is lowered by too tight winding on, one end of the L lever comes

endless band to turn the quadrant screw and raise the nut on same, thus giving
less winding. The second part of our Invention refers to the copping motion for
self acting mules or twiners, commonly called the shaper or builder; our improved
system of copping motion is a new arrangement of plates and jointed copping rail,
with suitable inclines specially arranged for crossing the winding on of the yarn
similar to a hand mule cop, or to cross the whole distance from the nose to top of
the lower cone. The copping rail at the back end is fitted up with an adjustable
stud in the usual manner for varying the length of the chase at pleasure. At the
opposite end of the copping rail is mounted a loose incline by means of a small stud
at the bottom side of the said incline; at one end is a stud, and the incline is made
of a suitable shape to rest upon a shaper plate which varies its angle. At one end
of this incline is coupled by means of a stud another incline of a suitable shape to
rest upon a shaper plate to vary its angle. This copping rail and the said inclines
are mounted upon four shaper plates, which are actuated by a screw and builder
wheel in the usual way. Another portion of our Invention refers to the spindles of
spinning and doubling machines, and consists in the application to spindles having
a removable or loose lower oil cup or reservoir of a spiral wire which is wound
round the spindle and which nearly fills the space between spindle and bolster, and
having any part of a turn or number of turns upon the spindle. This secures
perfect lubrication.
Another part of our Invention consists in an arrangement of mechanism for
governing the rise of the copping faller at a suitable speed to coil the yarn around
the spindle blade free from snarls.
We fix upon the copping faller a cam, the face of which works against the face
of a second cam which is mounted upon a bracket and stud fixed to the carriage
square. Upon the boss of the second cam is fixed a pulley or chain wheel. The
said cam is connected with the tin roller shaft by means of a band, strap, or chain,
or any suitable means. Upon the tin roller shaft is mounted a pulley or chain
wheel connected with a ratchet wheel on tin roller shaft by the usual click catch
and springs or by a cone in the usual way.
Our object is to control the speed of the rise of the faller by means of the cam
connected with the tin roller.

Bolton, in the County of Lancaster, Machine Maker, and ROBERT CROMPTON
TONGE, of the same Place, Engineer. "IMPROVEMENTS IN MACHINERY FOR
SPINNING AND DOUBLING."
The first part of our Invention relates to the governor motion for automatically
regulating the winding on of a self acting mule or twiner during the formation of
the cop bottom, and consists in a method of regulating the connection between the
usual endless band (connected with the quadrant) and the fallers by an arrange-
ment of mechanism which can be engaged and disengaged by the rise or fall of the
counter faller by an apparatus which is weighted very lightly. The second part of
our Invention relates to the copping motion for self acting mules or twiners
commonly called the shaper or builder. Our improved system of copping motion is
a new arrangement of plates and jointed copping rail with suitable inclines specially
arranged for crossing the winding on of the yarn similar to a hand mule cop or to
cross the whole distance from the nose to top of the lower cone. The third part of
our Invention relates to the spindles of spinning and doubling machines, and
consists in the application to spindles having a removable or loose lower oil cup or
reservoir of a spiral wire which is wound round the spindle and which nearly fills
the space between spindle and bolster, and having any part of a turn or number of
turns upon the spindle.
And in order that our Invention may be fully understood, we will describe the
accompanying two Sheets of Drawings.
In performing the first part of our Invention illustrated on Sheet by Figs. 1
and 2, we employ the usual governor horns mounted upon the copping fallers a
and counter fallers b; to these horns is connected one end of an L shaped lever c
by means of a chain passing over a pulley connected to a weight d on the L lever.
The lever swings on a stud on the carriage square; upon the other end of the
✓ lever is fixed a toothed shaped finger e; when the counter faller b is lowered by
the yarn being wound on too rapidly, the end of the L lever connected to the
fallers is lowered, which causes the finger e on the other end of the L lever to
come in contact with a half clutch box f on the face of which are projections.
This half clutch box forms a pulley on which are two V shaped or rounded grooves,
and it turns on a stud fixed to a bracket which is secured to the carriage square,
and on the same bracket is mounted a carrier pulley 9. An endless band is passed
around the said half clutch box and carrier pulley, and over the pulley connected
to the quadrant h. When the counter faller is lowered by too tight winding on
the finger e on the end of the L lever comes in contact with the half clutch box ƒ
and prevents it revolving, which causes the endless band to turn the quadrant screw
and raise the nut i on the same, thus giving less winding. The second part of our
Invention is illustrated on Sheet 1 by Figs. 3 and 4; j is the copping rail, the back
end of which is fitted with an adjustable stud k resting on a shaper plate r, in the
usual manner for varying the length of the chase at pleasure. At the opposite end
of the copping rail j is a stud m which rests on a shaper plate n; at this end of
the copping rail is also mounted a loose incline by means of a small stud; the
incline is made of a suitable shape to rest upon a shaper plate o which varies its
angle. At one end of this incline is coupled by means of a stud another incline p
of a suitable shape to rest upon a shaper plate q to vary its angle. The four
shaper plates r, n, o and q, upon which the copping rail j and the said inclines (

page_text: and p are mounted are actuated by a screw and builder wheel in the usual way.
The third part of our Invention illustrated on Sheet 2 by Fig. 5 refers to the spindles
of spinning and doubling machines, and consists in the application to spindles
having a removable or loose lower oil cup or reservoir of a spiral wire s, which is
wound round the spindle, and which nearly fills the space between spindle and
bolster, and having any part of a turn or number of turns upon the spindle. This
secures perfect lubrication.
Since our Provisional Specification. was left at the office of the Commissioners of
Patents on the Third December 1880, we have learned that the use of cams for
governing the rise of the copping faller as therein described is not novel, we
therefore do not clain the use of the said cams.
Having thus particularly described our said Invention, and the manner of
performing the same, we would have it understood that we do not restrict ourselves
to the precise details herein described or delineated, but that what we believe to be
novel and original, and claim as the Invention secured to us by the herein before
in part recited Letters Patent is,―
1. The L shaped lever with the clutch box and pulley mounted upon the
carriage, and connected to the fallers for regulating automatically the winding on
during the formation of the cop bottom, substantially as shown and described in
reference to Figs. 1 and 2.
2. The combination and arrangement of the copping rail j, incline 1, incline p,
plate o, and plate q, substantially as and for the purpose shown and described.
3. The spiral & applied to the spindles of spinning and doubling machines having
loose oil cups or reservoirs, substantially as and for the purpose shown and
described.
In witness whereof, we, the said Benjamin Alfred Dobson and Robert
Crompton Tange have hereunto set. our hands and seals this Twenty
