LETTERS PATENT to William Winter, of Leeds, in the County of
York, for the Invention of "IMPROVEMENTS IN SEWING MACHINES AND
IN MACHINERY OR APPARATUS FOR WINDING
INDING THE THREAD ON TO THE SPOOLS OF
BOBBINS."
Sealed the 29th November 1870, and dated the 1st June 1870.
PROVISIONAL SPECIFICATION left by the said William Winter at the
Office of the Commissioners of Patents, with his Petition, on the
1st June 1870.
I, WILLIAM WINTER, of Leeds, in the County of York, do hereby
declare the nature of the said Invention for "IMPROVEMENTS IN SEWING
MACHINES AND IN MACHINERY OR APPARATUS FOR WINDING THE THREAD ON TO THE
SPOOLS OR BOBBINS," to be as follows:-
The improvements which relate to sewing machines consist,-
Firstly. In the use of a large spool or bobbin containing a much
larger quantity of thread than hitherto in use. By the use of such
spools a great saving of time and labour to the operator is obtained on

page_text: account of the bobbins or spools being supplied ready filled with thread.
The shuttle has an exterior form similar to those of ordinary construc-
tion, but is provided with a hinged lid or cover having two male centres
on which the bobbins or spools are mounted and allowed to revolve
freely.
Secondly. In the employment of a hollow or box cam having its
interior filled with sawdust or other suitable non-conductor of sound.
Thirdly. In the mode of driving the shuttle. On the cam shaft I
mount a disc carrying a crank pin which works in the slot of a radial
arm, giving to it a reciprocating motion which is transmitted through
the shuttle rod to the shuttle carrier containing the shuttle. The end of
the shuttle rod is provided with an adjustable coupling which is arranged
so as to hook on to a stud on the shuttle carrier; this can be released at
pleasure, and the shuttle taken out without stopping the machine. The
adjustable coupling may be retained on the shuttle carrier stud by a
spring or other suitable means.
"
Fourthly. When "bell cams are used in having the motion for
driving the shuttle, needle, and feed motion in one boss.
Fifthly. Instead of a cam a tappet motion for actuating the feed
motion as in the Specification of my Patent, No. 3969 (1868), I use a
disc with an adjustable crank pin to which is connected one end of a
connecting rod, the other end being attached to a lever which transmits
motion to the catches, thereby actuating the feed wheel. Instead of
tightening the thread by means of the needle bar I employ a cam
motion acting upon a lever. By this arrangement I am able to in-
crease or diminish the required stroke of the lever to suit the various
sizes of shuttle. But on machines where a lever motion is used for
actuating the needle bar instead of the revolving shaft I employ a second
lever for increasing or diminishing the required stroke; to attain this I
actuate the said second lever by means of a pin fixed on the needle
driver or lever passing through a slot in the second lever, near the centre
on which it radiates, and not at the end where it has hitherto been placed.
Sixthly. In placing the thread or driving wheel in such a position
that it may be worked by hand instead of treadle. In this case I
mount a crank handle on the end of the treadle or driving wheel
shaft.

page_text: Seventhly. In order to lessen the amount of labour attending the
working of sewing machines, caused by the atmospheric resistance, I make
the arms in the wheels very light, and by preference of steel.
The machinery or apparatus for winding the thread on to the spools
or bobbins is constructed as follows:-On a frame I mount a cylinder
which imparts a rotary motion to the bobbins or spools, these being
placed between centres at the forked end of a lever or levers mounted on
a shaft in suitable bearings. The bobbins or spools are made to
revolve by being brought in contact with the revolving cylinder, the
necessary pressure being supplied by levers and weights or other
mechanical means.
I also provide brackets for carrying the hanks or bobbins, from
which the thread passes through guides on to the spools or bobbins;
these guides are provided with a traversing motion for the purpose of
distributing the thread evenly. By this arrangement spools or bobbins of
thread may be supplied ready for use in the same manner as thread used
for ordinary hand sewing.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said William Winter in the Great Seal Patent Office on
the 1st December 1870.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, WILLIAM
WINTER, of Leeds, in the County of York, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the First day of June, in the year of
our Lord One thousand eight hundred and seventy, in the thirty-fifth
year of Her reign, did, for Herself, Her heirs and successors, give and
grant unto me, the said William Winter, Her special licence that I,
the said William Winter, my executors, administrators, and assigns, or
such-others as I, the said William Winter, my executors, administrators,
and assigns, should at any time agree with, and no others, from time to

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 "IMPROVEMENTS IN SEWING MACHINES

page_text: AND IN MACHINERY OR APPARATUS FOR WINDING THE THREAD ON TO THE SPOOLS
OR BOBBINS," upon the condition (amongst others) that I, the said
William Winter, 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 calendar
months next and immediately after the date of the said Letters Patent.
NOW KNOW YE, that I, the said William Winter, 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 Drawings,
and to the letters of reference marked thereon, that is to say :-

motion, as in the Specification of my Patent, No. 3969 (1868), I use a

guides are provided with a traversing motion for the purpose of dis-
tributing the thread evenly. By this arrangement spools or bobbins of
thread may be supplied ready for use in the same manner as thread used
for ordinary hand sewing.
In order that my Invention may be more completely understood, I
herein give reference to three Sheets of Drawings shewing the improve;
ments.
DESCRIPTION OF DRAWINGS.
Sheet 1, Figs. 1, 2, and 3 represent an arrangement of a large shuttle,
Fic 1 being a plan shewing the shuttle onen·
Fix 2
C side alavati

page_text: of the same; and Fig. 3, a cross section shewing the shuttle closed and
the bobbin or spool in position. The shuttle has an exterior form
similar to those of ordinary construction, but is provided with a hinged
lid or cover a having two male centres 6, 6, between which the bobbin
or spool is mounted and allowed to revolve freely.
The second part of this Invention consists in the employment of a
hollow box cam having its interior filled with sawdust or other suitable
non-conductor of sound, as shewn at a, Fig. 4, enclosed and secured
therein by means of a plate 6 held in position by the screws c, in Figs. 4
and 5, which latter is a full-face elevation of the box cam.
The third part is shewn in Figs. 6, 7, and 8. Fig. 6 is a side
elevation of a sewing machine of ordinary construction. On the cam
shaft a I mount a disc 6 carrying a crank pin c which works in the
slot d of a radial arm e, giving to it a reciprocating motion, which is
transmitted through the shuttle rod f to the shuttle carrier g, containing
the shuttle h, as shewn in Fig. 7, which is a part plan. The end of the
shuttle rod f is provided with an adjustable coupling rod i which is
arranged so as to hook on to a stud j on the shuttle carrier g, and is
retained in position by the spring k working against the under side
of the plate l. The shuttle rod ƒ can be released at pleasure from
the shuttle carrier 9, and the shuttle taken out without stopping the
machine.
The fourth part is shewn at Figs. 1 and 2 on Sheet 2, and applies to
machines fitted with "bell cams." The motion for driving the shuttle,
needle bar, and feed levers are all in one boss. The side cam a is to
give motion to the needle bar. The cam 6 on the periphery actuates
the shuttle, and the cam c gives the necessary motion to the feed
levers.
The fifth part is shewn at Fig. 9, Sheet 1. Instead of a cam or
tappet motion for actuating the feed motion as in the Specification of my
Patent, No. 3969 (1868), I use a disc a having an adjustable crank
pin b, to which is connected one end of a connecting rod, the other end
of the latter, c, being attached to a lever d, which transmits motion to the
It will be seen that the
catches e, thereby actuating the feed wheel f.
catches e are so arranged as to prevent any danger of the teeth in the
feed wheelf not being caught, and it will be readily understood that
any required number of catches may be employed. These catches fit

page_text: into a grooved plate g on the lever d, and are held in position by a
cover screwed to the face of the plate 9, and brought down to their
work by means of the spiral springs shown in dotted lines. The stroke
of the lever d may be increased or diminished by the movement of the
finger or pointer h having a pin i at the end which retains it in any of
the holes 1, 2, 3, 4, 5, 6, on the stitch dial. The other end of the
pointer his carried on the boss j by a stud k. The crank pin b is
carried by a slide fitting into the boss j, and passes through the pointer h.
It will be readily understood that by changing the pointer from one of
the holes to another the distance of the centre of the crank pin 6 from
that of the boss is altered, thereby a greater or less motion is imparted

clip or break which consists of a bracket m which may be attached to
the table of the sewing machine, carried over the feed wheel, and
brought down on each side, as shewn. n is a set screw which presses
the feed wheel against a piece of leather or other suitable material,
which is fitted on to the bracket m at the back of the feed wheel; by
this means it is retarded, and any unnecessary backward or forward
motion prevented. Instead of tightening the thread by means of the
needle bar I employ a cam motion acting upon a lever. By this means
I am able to increase or diminish the required stroke of the lever to
suit the various sizes of shuttles. But on machines where a lever
motion is used for actuating the needle bar instead of a revolving shaft
I employ a second lever for increasing or diminishing the required
stroke. To attain this I actuate the second lever by means of a pin
fixed on the needle driver passing through a slot in the second lever
near the centre on which it radiates, and not at the end where it has
hitherto been placed.
In
The sixth part consists in placing the treadle or driving wheel in
such a position that it may be worked by hand instead of treadle.
this case I mount a crank handle on the end of the treadle or driving
wheel shaft.
The seventh part consists in making the arms of the wheels light and
of steel in order to lessen the amount of labour attending the working
of sewing machines caused by the atmospheric resistance. The machinery
or apparatus for winding the thread on to the spools or bobbins is
constructed as follows. It is shewn on Sheets 2 and 3.

page_text: Fig. 2, Sheet 2, represents a side elevation; Fig. 3 an end elevation.
Sheet 3 represents a plan of the machine looking at the top. On a
frame a I mount a cylinder b, which imparts a rotary motion to the
bobbins c, these being placed between centres at the ends of the levers d
mounted on the shaft e, supported in the bearings f. The bobbins are made
to revolve by being brought in contact with the revolving cylinder b,
the necessary pressure being supplied by pulley and weight, as shown,
or other mechanical means. I also provide the bracket g for carrying
the hanks or bobbins h from which the thread passes through the guide
bar on to the bobbins c. The guide bar i has a traversing motion pro-
duced by the cam ; through the levers k, carried by the adjustable
bracket and fixed bracket Z. The traverse of the guide bar i may be
regulated by the raising or lowering of the adjustable bracket 1. Motion
is imparted by the cylinder 6 through worms m and worm wheels n to
the cone o, and thence by means of a strap u to the cone p, which
transmits the motion through the gearing 9 and r to the cam j. The
speed of the cam is regulated to suit the various sizes of bobbins or
spools c by means of the strap guide 8, which may be worked to any
required position on the cones by means of the screw t carrying with it
the belt or strap u. The various points may be fixed or marked on
the bar which may be graduated. By this arrangement bobbins may
be supplied ready for use in the same manner as thread used for ordinary
hand sewing.
Having now described the nature of my said Invention, and the
manner in which the same is to be performed, I would remark in
conclusion that I do not confine myself to the precise details herein
set forth, nor do I claim all the parts which I have shewn or mentioned;
but what I do claim and desire to have secured to me by Letters Patent
are,-
Firstly. The employment of a hollow box cam, substantially as and
for the purpose set forth.
Secondly. The arrangement for driving the shuttle, substantially as
set forth.
Thirdly. The arrangement and construction of bell cams, as set
forth.
Fourthly. The arrangement of the feed motion, substantially as
described.

page_text: Fifthly. The arrangement of bobbin winding apparatus, substantially
as described.
In witness whereof, I, the said William Winter, have hereunto set
my hand and seal, this Thirtieth day of November, in the year of
our Lord One thousand eight hundred and seventy.
