ETTERS PATENT to William Tasker, of Halifax, in the County of
York, Patent Agent and Consulting Engineer, for the Invention of
" AN IMPROVED BOBBIN WINDER
"
OR APPARATUS FOR WINDING BOBBINS,
REELS, OR SPOOLS FOR SEWING MACHINES AND OTHER Purposes."—A com-
munication from abroad by Moses Cook and Moses Gorham Cook,
of Ashfield, Massachusetts, in the United States of America, and
Horace Sprague Nichols, of Bayonne, New Jersey, and Ellis
Magerison, of Tingley Station, New Jersey, in the United States of
America, aforesaid.
Scaled the 21st September 1875, and dated the 22nd March 1875.
PROVISIONAL SPECIFICATION left by the said William Tasker at the
Office of the Commissioners of Patents, with his Pitition on the
22nd March 1875.

I, WILLIAM TASKER, of Halifax, in the County of York, Patent
Agent and Consulting Engineer, do hereby declare the nature of the said
Invention for "AN IMPROVED BOBBIN WINDER' OR APPARATUS FOR WINDING
BOBBINS, REELS, OR SPOOLS FOR SEWING MACHINES AND OTHER PURPOSES," a com-
munication to me from abroad by Moses Cook and Moses Gorham Cook,

page_text: of Ashfield, Massachusetts, in the United States of America, and Horace
Sprague Nichols, of Bayonne, New Jersey, and Ellis Magerison, of
Tinley Station, New Jersey, in the United States of America, aforesaid,
to be as follows:-
This Invention relates to a traverse mechanism or apparatus for
winding bobbins, more especially for sewing machines, but applicable
also for winding bobbins, reels, or spools to be used for other purposes.
It consists of a drum with a reversing cam groove for working the
traversing guide backward and forward along the bobbin reel or spool.
This drum has the necessary slow motion for moving the guide imparted
to it by a pawl and a frictional gripping strap, the pawl being worked by
a crank tappet cam or eccentric on the bobbin turning shaft which
receives motion from the sewing machine wheel through the medium of
a friction wheel or other driving means, the said friction gripping strap
being attached to the pawl by a moveable fastening connected to one end
of a lever or pointer to regulate the extent of its movements so as to
turn the drum faster or slower, according to the size or thickness of the
thread to be wound, and the drum having a friction strap and spring
for holding it when released by the gripping strap and spring.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said William Tasker in the Great Seal Patent Office
on the 22nd September 1875.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, WILLIAM
TASKER, of Halifax, in the County of York, Patent Agent and Consulting
Engineer, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Twenty-second day of March, in the year
of our Lord One thousand eight hundred and seventy-five, in the thirty-
eighth year of Her reign, did, for Herself, Her heirs and successors, give
and grant unto me, the said William Tasker, Her special licence that
I, the said William Tasker, my executors, administrators, and assigns,
or such others as I, the said William Tasker, my executors, admini-
strators, 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 "AN IMPROVED BOBBIN WINDER OR
APPARATUS FOR WINDING BOBBINS, REELS, OR SPOOLS FOR SEWING MACHINES AND
OTHER PURPOSES,' a communication to me from abroad by Moses Cook
and Moses Gorham Cook, of Ashfield, Massachusetts, in the United
States of America, and Horace Sprague Nichols, of Bayonne, New
Jersey, and Ellis Magerison, of Tinley Station, New Jersey, in the
United States of America, aforesaid, upon the condition (amongst
others) that I, the said William Tasker, my executors or admini-
strators, 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 calendar months next and immediately after the date
of the said Letters Patent.
NOW KNOW YE, that I, the said William Tasker, do hereby declare
the nature of the said Invention, and in what manner the same is to
be performed, to be particularly described and ascertained in and by the
following statement and accompanying Sheet of Drawings (that is to
say):
This Invention relates to a traverse mechanism apparatus for winding
bobbins, more especially for sewing machines, but applicable also for
winding bobbins, reels, or spools to be used for other purposes. It
consists of a drum with a reversing cam groove for working the
traversing guide backward and forward along the bobbin reel or spool.
This drum has the necessary slow motion imparted to it by a pawl and
a frictional gripping strap, the pawl being worked by a crank tappet
cam or eccentric on the bobbin turning shaft which receives motion
from the sewing machine wheel through the medium of a frictional
wheel or other driving means, the said friction gripping strap being
attached to the pawl by a moveable fastening connected to one end of a
lever or pointer to regulate the extent of its movements so as to turn the
drum faster or slower, according to the size or thickness of the thread to
be wound, and the drum having a friction strap and a spring for holding
it when released by the gripping strap and spring.
In order that this Invention may be more fully understood, I herein
give reference to an accompanying Sheet of Drawings marked with
figures and letters of reference.

page_text: A is the bobbin mounted in the axis B and C, the axis B being
capable of withdrawal, and on the axis C is a friction wheel D for
imparting rotation to the bobbin, which rotation may be either com-
municated by hand or from the driving wheel of the sewing machine.
The rotation is securely imparted to the bobbin by means of a pin a on
the axis B entering the flange of the bobbin; E is the traversing guide
which is worked backward and forward by means of the reversing cam
groove F, the pin f entering the groove of the cam to which rotation is
imparted by means of the pawl G and gripping strap H, one end of
which is attached to the spring hand the other to the moveable link K.
This link K is attached to the end of the lever or pointer L, by moving
which the extent of the motion communicated to the drum may be
regulated. The pawl G is hinged at g, the clip or fork at the end
thereof clasps the eccentric ⁄ on the end of the axis C. The forward
movement of the pawl slackens the gripping strap H and allows it to be
taken up by the spring h, the backward movement tightens the strap
and turns round the drum. On the release of the drum by the gripping
strap it is prevented from receding by means of a strap M, one end of
which is attached by pin N and the other to a spring similar to the
spring ; P is a plate for pressing against the thread when being wound
on the bobbin; this plate is hinged at p and the lower end s acted on by
spring s¹. To secure the thread at starting a nick is cut in one of the
bobbin flanges.

I claim the construction and employment of winding apparatus,
substantially as herein shewn and described.
In witness whercof, I, the said William Tasker, have hereunto set
my hand and scal, this Twenty-first day of September, in the
year of our Lord One thousand cight hundred and seventy-
five.
