IMPROVEMENTS IN SEWING MACHINES
Year: 1870

page_text: LETTERS PATENT to William Taylor, of Great Driffield, in the County
of York, for the Invention of "IMPROVEMENTS IN SEWING MACHINES."
PROVISIONAL SPECIFICATION left by the said William Taylor at the
Office of the Commissioners of Patents, with his Petition, on the
17th November 1870.
I, WILLIAM TAYLOR, of Great Driffield, in the County of York, do
hereby declare the nature of the said Invention for "IMPROVEMENTS IN
SEWING MACHINES," to be as follows:-
The Invention has for its object improvements in sewing machines,
and relates to the application of a novel arrangement of means for
driving the same whereby it is rendered impossible to drive the working
parts of the machine backwards, and whereby when the reel or bobbin
is being filled the working parts of the machine are not operated. For
this purpose I fix a pulley or drum on the end of the driving shaft of
the machine. The hand wheel having a groove corresponding with one
on the pulley, but on the inside of the rim, runs loosely outside of this.

page_text: Between the two grooves a small disc or loose whicel or ball is placed.
This disc is made by preference of metal with a ring of india-rubber
stretched round it, but it may be made entirely of metal, india-rubber,
leather, vulcanite, or other substance. The grooves in the wheel and
driving pulley and the periphery of the disc or ball may be either smooth or
serrated, or roughened. The action is such that when the hand wheel is
turned in the direction to force the disc in between itself and the driving
pulley the latter will revolve in an opposite direction, but if the wheel
be turned the reverse way the disc will be lifted a little and the driving
pulley will not revolve. The disc may be prevented from falling out
of its place either by forming the wheel of a close pattern or by passing
a screw or pin through the centre of the disc, the hole in the centre of
which should be much larger than the pin to allow of its working
freely. By operating the driving wheel in the contrary direction to
that employed when working the machine the reel or bobbin may
be filled without working the operating parts of the machine. The
arrangement before described is that which I prefer, but I would have it
understood that the same may be modified without departing from my
Invention.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said William Taylor in the Great Seal Patent Office
on the 17th May 1871.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, WILLIAM
TAYLOR, of Great Driffield, in the County of York, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Seventeenth day of November, in the
year of our Lord One thousand eight hundred and seventy, in the
thirty-fourth year of Her reign, did, for Herself, Her heirs and suc-
cessors, give and grant unto me, the said William Taylor, Her special
licence 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

page_text: Islands, and Isle of Man, an Invention for "IMPROVEMENTS IN SEWING
MACHINES," 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.
NOW KNOW YE, that I, the said William Taylor, 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 thereof, that is to say :-
The Invention has for its object improvements in sewing machines,
and relates to the application of a novel arrangement of means for driving
the same, whereby it is rendered impossible to drive the working parts
of the machine backwards, and whereby when the reel or bobbin is
being filled the working parts of the machine are not operated. For
this purpose I fix a pulley or drum on the end of the driving shaft of
the machine. The hand wheel having a groove corresponding with one
on the pulley, but on the inside of the rim, runs loosely outside of this.
Between the two grooves a small disc or loose wheel or ball is placed.
This disc may be made of metal with a ring of india-rubber stretched round
it, or it may be made entirely of metal, india-rubber, leather, vulcanite,
or other substance. The grooves in the wheel and driving pulley and
the periphery of the disc or ball may be either smooth or serrated or
roughened. The action is such that when the hand wheel is turned in
the direction to force the disc in between itself and the driving pulley
the latter will revolve in an opposite direction, but if the wheel be turned
the reverse way the disc will be lifted a little and the driving pulley
will not revolve. The disc may be prevented from falling out of its
place either by forming the wheel of a close pattern or by passing a screw
or pin through the centre of the disc, the hole in the centre of which
should be much larger than the pin to allow of its working freely. By
operating the driving wheel in the contrary direction to that employed
when working the machine the reel or bobbin may be filled without
working the operating parts of the machine. The arrangement before
described is that which I prefer, but I would have it understood that the
same may be modified without departing from my Invention.

page_text: DESCRIPTION OF THE DRAWINGS.
Figure 1 is an end view of so much of a sewing machine as will enable
me to describe the application of my Invention thereto, and Figure 2
is a sectional plan of the driving or hand wheel and pinions.
a is the driving or hand wheel, which is mounted on a stud or axis a¹
as shown, and is formed around its internal periphery with a V shaped
recess or groove a². b is a pulley drum or pinion fixed on the end
of the driving shaft c of the machine. This pulley drum or pinion 6 is
provided around its external periphery with a V shaped groove or recess b¹
corresponding with the groove or recess a³ in the hand wheel a. Between
In
the two grooves or recesses a² and 6' a small loose disc wheel or pinion d
(or it may be a ball) is placed, the edge of which is formed of a suitable
shape to fit the grooves or recesses a², b'. By turning the hand wheel a
in the direction of the arrow a* the loose disc wheel or pinion d is forced
in between the grooves a², b¹, thereby driving the pulley drum or
pinion b in the reverse direction to that of the hand wheel as indicated
by the arrow 6*, but by turning the hand wheel a in the contrary
direction to that of the arrow a* the loose disc wheel or pinion d will be
slightly raised and the pulley drum or pinion 6 will not revolve.
the Drawings the loose disc wheel or pinion d is shown to be prevented
falling out of its place by means of a guard e fixed to the frame, but if
desired the loose disc wheel or pinion d may be held in position by
means of a screw or pin passed through a hole in the centre thereof,
such hole being made much larger than the pin to allow of its working
freely. fis the reel or bobbin holder, which when not required to be
used is held away from the hand wheel a by means of a spring f¹ as
shown or in other suitable way, but when it is required to fill a reel or
bobbin then the bobbin holder f is released from the spring f¹ when
it will fall and rest against the inner periphery of the hand wheel a.
Then by turning the hand wheel a in the contrary direction to that
of the arrow a* the reel holder will be rotated without working the
operating parts of the machine. Instead however of forming the hand
wheel a and drum pulley or pinion 6 with smooth V shaped grooves
or recesses and the loose dise wheel or pinion with a smooth inverted

page_text: V edge to work in such grooves, such grooves and edge may be serrated or
roughened, or the driving surfaces of the hand wheel a, the drum pulley
or pinion b, and the loose wheel or disc d may be formed with serrated.
edges extending straight across their peripheries in a somewhat similar
manner to the teeth of ordinary wheels as shown at Figures 3, or other
suitable shape may be given thereto. The loose disc wheel, pinion, or
ball & may be made of metal with a ring of india-rubber stretched round
it, or it may be made entirely of metal, india-rubber, leather, vulcanite, or
other substance, but I prefer to form it of stout uncurried leather when
used in V shaped grooves, and of vulcanite when used with serrated
edges without grooves.
Having thus described the nature of my said Invention, and the mode
which I have found to answer in carrying the same into effect, I would
have it understood that the arrangement of the driving surfaces of the
wheel and pinions may be varied without departing from the nature
of my Invention, as in some cases the pulley 6 and the loose wheel d
may be placed outside of the hand wheel; but what I do claim is, the
novel arrangement of means for driving sewing machines, substantially
as herein shown and described, whereby it is rendered impossible to
drive the working parts of the machine backwards, and whereby the
reel or bobbin may be filled without at the same time working the
operating parts of the machine.
In witness whereof, I, the said William Taylor, have hereunto set
my hand and seal, this Fifth day of May, in the year of our
Lord One thousand eight hundred and seventy-one.
