IMPROVEMENTS IN SEWING MACHINES AND IN SHUTTLES FOR THE SAME.
Year: 1874

page_text: LETTERS PATENT to William Taylor, of Great Driffield, in the County
of York, Sewing Machine Manufacturer, for the Invention of
"IMPROVEMENTS IN SEWING MACHINES AND IN SHUTTLES FOR THE SAME.".
Partly a communication from abroad by Johann Heinrich Rudolph
Dreyer and Heinrich Schipmann, both of Hamburg, in the Empire
of Germany.
Sealed the 26th June 1874, and dated the 4th May 1874.
PROVISIONAL SPECIFICATION left by the said William Taylor at the
Office of the Commissioners of Patents, with his Petition, on the
4th May 1874.
I, WILLIAM TAYLOR, of Great Driffield, in the County of York,
Sewing Machine Manufacturer, do hereby declare the nature of the said
Invention for "IMPROVEMENTS IN SEWING MACHINES AND IN SHUTTLES FOR THE
'SAME," partly my own Invention and partly the result of a communication
to me from abroad by Johann Heinrich Rudolph Dreyer and Heinrich
Schipmann, both of Hamburg, in the Empire of Germany, to be as
follows:-
The Invention relates, firstly, to improvements upon an Invention

page_text: for which Letters Patent were granted to me dated November 17, 1870,
No. 3011. For this purpose instead of the intermediate wheel, disc, or
ball being perfectly loose and independent of any mechanical means for
controlling its position I mount it upon one end of a lever operated by a
spring to press the intermediate wheel, disc, or ball against the hand
wheel, by which means the intermediate wheel, disc, or ball is prevented
slipping, and motion is regularly communicated from the hand wheel to
the driving shaft of the machine. On the other end of this lever carrying
the intermediate wheel, disc, or ball, I mount the spool holder, and I
arrange the lever so that one end or the other can be readily placed in
contact with the hand wheel whereby, when driving the machine for
sewing, the spool holder is held away from the driving wheel, and when
the spool holder is in operation the operating parts of the machine
remain stationary.
The Invention relates, secondly, to means for securely retaining the
shuttle in the shuttle carrier or holder, and for readily releasing the same
therefrom in that class of machine in which the shuttle travels against
a vertical face plate, and is caused to move in a segmental, circular, or
eccentric path underneath the work plate. For this purpose the two
horns acting upon the upper side of the shuttle to hold it in position are
formed upon a lever mounted at one end thereof upon a centre of motion
fixed to the shuttle carrier. This lever has a slot formed therein which
works upon a screw or stud fixed in the shuttle carrier. To this lever is
fixed a spring catch which has formed therein a hole to fit the head of
the screw or stud. Thus by raising the spring catch and turning the
lever on its axis of motion the shuttle is released from its carrier and by
the reverse action it is securely-held therein.
The Invention relates, thirdly, to improvements in shuttles for sewing
machines whereby facility is afforded for threading the same, and the
tension on the thread is capable of easy regulation. For this purpose
the holes in the shuttle are dispensed with and in lieu thereof a slit or
opening is formed therein into which the thread is readily passed. This
slit or opening is guarded by a wire extending across the same and fixed
at one end only to the shuttle; the thread passes from this slit or
opening to a disc on the outside of the shuttle but fixed to a spring on
the inside of the shuttle.
The regulation of the tension is effected by means of a screw passing
through the shell of the shuttle and acting upon the said spring. By

page_text: turning the said screw in one or the other direction the disc is caused to
bear more or less tightly upon the thread and thereby regulate the
tension on the shuttle thread as may be desired.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said William Taylor in the Great Seal Patent Office on
the 4th November 1874.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, WILLIAM
TAYLOR, of Great Driffield, in the County of York, Sewing Machine
Manufacturer, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Fourth day of May, in the year of
our Lord One thousand eight hundred and seventy-four, in the thirty-
seventh year of Her reign, did, for Herself, Her heirs and successors,
give and grant unto me, the said William Taylor, Her special license that
I, the said William Taylor, my executors, administrators, and assigns, or
such others as I, the said William Taylor, 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 " IMPROVEMENTS IN SEWING MACHINES
AND IN SHUTTLES FOR THE SAME," partly my own Invention and partly the
result of a communication to me from abroad by Johann Heinrich
Rudolph Dreyer and Heinrich Schipmann, both of Hamburg, in the
Empire of Germany, upon the condition (amongst others) that I, the
said William Taylor, 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.

page_text: performed, to be particularly described and ascertained in and by the
following statement thereof, that is to say :—
The Invention relates, firstly, to means for securely retaining the
shuttle in the shuttle carrier or holder and for readily releasing the same
therefrom in that class of machine in which the shuttle travels against
a vertical face plate and is caused to move in a segmental, circular, or
eccentric path underneath the work plate. For this purpose the two
horns acting upon the upper side of the shuttle to hold it in position are
formed upon a lever mounted at one end thereof upon a centre of
motion fixed to the shuttle carrier. This lever has a slot formed therein
which works upon a screw or stud fixed in the shuttle carrier. To this
lever is fixed a spring catch which has formed therein a hole to fit the
head of the screw or stud. Thus by raising the spring catch and turning
the lever on its axis of motion the shuttle is relcased from its carrier,
and by the reverse action it is securely held therein.
"
- The Invention relates, secondly, to improvements in shuttles for
sewing machines whereby facility is afforded for threading the same,
and the tension on the thread is capable of easy regulation. For this
purpose the holes in the shuttle are dispensed with, and in lieu thereof
a slit or opening is formed therein into which the thread is readily
passed; this slit or opening is guarded by a wire extending across the
same and fixed at one end only to the shuttle, the thread passes from
this slit or opening to a disc on the outside of the shuttle but fixed to a
spring on the inside of the shuttle.
The regulation of the tension is effected by means of a screw passing
through the shell of the shuttle and acting upon the said spring. By
turning the said screw in one or the other direction the disc is caused to
bear more or less tightly upon the thread and thereby regulate the
tension on the shuttle thread as may be desired.
And in order that the said Invention may be more clearly understood
and readily carried into effect I will proceed, aided by the accompanying
Drawings more fully to describe the same.
DESCRIPTION OF THE DRAWINGS.
Figure 1 is a sectional end elevation, Figure 2 is a sectional side
elevation, and Figure 3 is a sectional plan of parts of a sewing machine
having the first part of the present Invention applied thereto: Figure 4.

page_text: is an inside view of the shuttle carrier separately; and Figure 5 is a
plan view thereof. I would here remark that this part of the said
Invention is shown applied to that class of machine for which I obtained
Letters Patent, dated August 20th, 1866, No. 2136, but it is also
applicable to other sewing machines in which the shuttle is caused-to
travel against a vertical face plate and is caused to move in a segmental;
circular, or eccentric path underneath the work plate.

page_text: At Figure 7 instead of employing a slit or opening e and guard wire f,
as in the arrangement shown at Figure 6, a single hole h is employed,
and instead of placing the spring g'inside the shuttle it is placed outside
thereof, and is formed in one piece with the disc or tension plate g, the
screw g² passing through the spring g¹ and screwing into the shell of the
shuttle.
I would here remark that the improvements in the mode of driving
sewing machines referred to in the first part of my Provisional Specifi-
cation does not possess such an amount of utility as to render it advisible
to make a claim thereto, and for this reason I do hereby disclaim such
parts.
Having thus described the nature of the said Invention and the mode
in which the same is carried into effect I would have it understood that
what I claim is,―
•
First. The improvements in the construction of shuttle carriers :
whereby the shuttle is securely retained therein and readily released
therefrom, in manner substantially as herein shown and described.
g
Secondly. I claim forming a shuttle with a slit or opening e,
and guard wire f, and with a tension disc or plate 9 connected to a
spring acted upon by a screw 92, in manner substantially as herein
shown and described, in lieu of forming the shuttle with the tension
holes ordinarily employed.
In witness whereof, I, the said William Taylor, have hereunto set
my hand and seal, this Twenty-ninth day of October, in the year
of our Lord One thousand eight hundred and seventy-four.
W TAYLOR. (7.0)
