Year: 1868

page_text: LETTERS PATENT to William Robert Lake, of the "International
Patent Office," No. 8, Southampton Buildings, Chancery Lane, in
the County of Middlesex, Consulting Engineer, for the Invention
of "IMPROVEMENTS IN SPINNING MACHINES."-A communication from
abroad by John Goulding, of Worcester, Massachusetts, United
States of America, Manufacturer.
Sealed the 7th March 1869, and dated the 31st December 1868.
PROVISIONAL SPECIFICATION left by the said William Robert Lake
at the Office of the Commissioners of Patents, with his Petition, on
the 31st December 1868.
I, WILLIAM ROBERT LAKE, of the International Patent Office,
No. 8, Southampton Buildings, Chancery Lane, in the County of
Middlesex, Consulting Engineer, do hereby declare the nature of the
said Invention for "IMPROVEMENTS IN SPINNING MACHINES," a communi-
cation, to be as follows:-
This Invention consists, first, in a flyer so arranged as to be suspended
directly from a hollow tube, the latter being provided with a pulley or

page_text: whirl or equivalent device by which the said flyer and tube are caused
to revolve, the yarn to be twisted, whether single or double, passing
through the said hollow tube, and the said flyer and tube with its whirl
being entirely independent of the bobbin spindle.
The said Invention consists, secondly, in the combination of the
bobbin with a swinging adjustable rail, in such manner that when the
said rail is let down for "doffing" the bobbins it can be swung out from
under the flyer, and thereby facilitate and expedite the operation of
" doffing."
The said Invention consists, thirdly, in a tension equalizing device
composed of a friction sleeve arranged to play upon the spindle, and
acted upon by a lever and spring in such a manner as to increase and
diminish the friction of the spindle, whereby the tension upon the yarn
is regulated, the friction being more or less as the bobbin is raised or
lowered, or as the yarn is wound upon the larger or smaller cir-
cumference thereof, and the action of the lever being governed by a
movable self-adjusting incline.
The parts of the mechanism to which my improvements relate are
supported upon a suitable frame. To one end of the hollow tube a
collar is secured. The said collar has projecting arms, which together
with rings form the flyer. The whirl is carried upon this hollow tube,
upon which a band may be placed for driving the flyer. The frame for
carrying the bobbin spindle is caused to move up and down by any of
the devices for that purpose now in use.
A friction sleeve plays upon
this spindle, and one end of a spring is attached to the said friction
sleeve, the other end being attached to a rock shaft, so that the power
of the spring upon the sleeve is greater or less in proportion as the
rock shaft is more or less turned. A crank or lever is made fast to
the rock shaft, and its outer end rests upon an incline cam, so that as
the spindle frame is moved up the lever slides up the incline cam,
which action causes the rock shaft to turn, and thus to increase the
strain of the spring upon the sleeve and to increase the friction upon
the bobbin spindle. The incline cam is arranged to slide freely upon
a rod, and as the inclined portion is limited by stops it is evident that
when the bent end of the lever has reached either of these stops it
will then move the incline with it, so that the incline is automatically

page_text: adjusted to the position of the bobbin. The frame to which the bobbin
spindle is attached moves in suitable ways in the main frame, so that
it is always held in a vertical position, except when it is at its lowest
point and ready for doffing, then the said spindle frame will swing
outward, it being prevented from swinging out too far by ears or stops
on the frame. The yarn to be twisted, or doubled and twisted, passes
through the hollow tube around one of the arms, then over one of the
rings, again around the arm, then over the other ring to the bobbin.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said William Robert Lake in the Great Seal Patent
Office on the 15th May 1869.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, WILLIAM
ROBERT LAKE, of the "International Patent Office," No. 8, Southampton
Buildings, Chancery Lane, in the County of Middlesex, Consulting
Engineer, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Thirty-first day of December, in the
year of our Lord One thousand eight hundred and sixty-eight, in the
thirty-second year of Her reign, did, for Herself, Her heirs and suc-
cessors, give and grant unto me, the said William Robert Lake, Her
special licence that I, the said William Robert Lake, my executors,
administrators, and assigns, or such others as I, the said William Robert
Lake, my executors, administrators, and assigns, should at any time
agree with, and no others, from time to time and at all times thereafter
during the term therein expressed, should and lawfully might make, use,
exercise, and vend, within the United Kingdom of Great Britain and
Ireland, the Channel Islands, and Isle of Man, an Invention for "Im-
PROVEMENTS IN SPINNING MACHINES," upon the condition (amongst others)
that I, the said William Robert Lake, my executors or administrators,
by an instrument in writing under my, or their, or one of their hands
and seals, should particularly describe and ascertain the nature of the
said Invention, and in what manner the same was to be performed, and
cause the same to be filed in the Great Seal Patent Office within six

Patent.
NOW KNOW YE, that I, the said William Robert Lake, do hereby
declare the nature of my said Invention, and in what manner the same
is to be performed, to be particularly described and ascertained in and
by the following statement, reference being had to the accompanying
Drawing forming a part of this Specification:-
This Invention consists, first, in a flyer so arranged as to be suspended
directly from a hollow tube, the latter being provided with a pulley or
whirl or equivalent device by which the said flyer and tube are caused
to revolve the yarn to be twisted, whether single or double, passing
through the said hollow tube, and the said flyer and tube with its whirl
being entirely independent of the bobbin spindle.
The said Invention consists, secondly, in the combination of the
bobbin with a swinging adjustable rail in such manner that when
the said rail is let down for "doffing" the bobbins it can be swung out
from under the flyer, and thereby facilitate and expedite the operation
of " doffing."
The said Invention consists, thirdly, in a tension equalizing device
composed of a friction sleeve arranged to play upon the spindle, and
acted upon by a lever and spring in such a manner as to increase and
diminish the friction of the spindle, whereby the tension upon the yarn
is regulated, the friction being more or less as the bobbin is raised or
lowered, or as the yarn is wound upon the larger or smaller cir-
cumference thereof, and the action of the lever being governed by a
movable self-adjusting incline.
In the accompanying Drawing, which represents the parts of a
spinning machine to which this Invention relates, Figure 1 is a front
view of the said improvements; Figure 2 is a side elevation of the same,
showing a bobbin in the position for doffing; Figure 3 is a perspective
view of the same. Similar letters indicate like parts in the three
Figures.
A designates a portion of a frame to which the said improvements
are attached; D is a hollow tube, to one end of which a collar C is
secured. The said collar C has projecting arms G, which together with
the rings H and I form the flyer; J is a "whirl"
upon
the hollow

page_text: tube D, upon which a band may be placed for driving the flyer;
B designates a frame for carrying a spindle L, and it is caused to
move up and down by any of the devices for that purpose now in use.
A friction sleeve M plays upon the spindle L. One end of a spring O
is attached to the said friction sleeve M, and the other to a rock shaft N,
so that the power of the spring upon the sleeve M is greater or less in
proportion as the rock shaft is more or less turned. P is a crank or lever
made fast to the rock shaft N, and its outer end rests upon an incline
cam Q, so that as the frame B is moved up the lever P slides up the
incline cam Q, which action causes the rock shaft N to turn, and thus
to increase the strain of the spring O upon the sleeve M, and to increase
the friction upon the bobbin spindle L. The incline Q is arranged to
slide freely upon a rod R, and as the incline portion is limited by the
stops q, q', it is evident that when the bent end of the lever P has
reached either of these stops it will then move the incline with it, so
that the incline is automattically adjusted to the position of the bobbin.
The frame B to which the bobbin spindle L is attached moves in suitable
ways in the frame A, so that it is always held in a vertical position,
except when the frame B is at its lowest point and ready for doffing,
then the frame will swing out, as shown in Figures 2 and 3, it being
kept from swinging out too far by ears S, S. The yarn to be twisted,
or doubled and twisted passes through the hollow tube D around one of
the arms G, then over the ring H, again around G, then over the ring I
to the bobbin E.
Having thus particularly described the said Invention, as com-
municated to me by my foreign correspondant, and shown how the
same may be conveniently and advantageously carried into practice,
I claim,-
First. The suspended flyer or its equivalent in combination with the
spindle, arranged and operating substantially in the manner and for
the purposes herein specified.
Second. The combination of the swinging frame, spindle, and bobbin,
or their equivalents, operating substantially in the manner and for the
purposes herein specified.
Third. The combination of the spindle L, sleeve M, spring O, rock
shaft N, lever P, sliding incline cam Q, and flyer, or their equivalents,

page_text: arranged and operating substantially as and for the purposes herein
specified.
In witness whereof, I, the said William Robert Lake, have here-
unto set my hand and seal, this Fifteenth day of May, One
thousand eight hundred and sixty-nine.
WILLIAM ROBERT LAKE. (L.S.)
