Year: 1871

page_text: LETTERS PATENT to Altham Pilling and Arthur Nussey, both of
Leeds, in the County of York, for the Invention of "IMPROVEMENTS
IN SEWING MACHINES."
Sealed the 13th October 1871, and dated the 20th April 1871.
PROVISIONAL SPECIFICATION left by the said Altham Pilling and
Arthur Nussey at the Office of the Commissioners of Patents, with
their Petition, on the 20th April 1871.
We, ALTHAM PILLING and ARTHUR Nussey, both of Leeds, in the
County of York, do hereby declare the nature of the said Invention
for "IMPROVEMENTS IN SEWING MACHINES," to be as follows:-
Firstly. The Invention relates to an arrangement for producing the
required motion to the needle bar and shuttle carrier.
Secondly. The construction of the shuttle.

page_text: are mounted two pairs of brackets, which may be made adjustable though
not necessarily so. A slide bar is mounted and fixed between each pair
of brackets, on which are fitted slide blocks so as to slide freely. The
lever for transmitting motion to the needle bar is attached to the upper
slide block, and the lever for transmitting motion to the shuttle carrier
is attached to the lower slide block. On the head is also mounted a
radial arm which is connected or coupled to the eccentric strap. By
the eccentric being made to revolve motion is given to the eccentric
strap, and transmitted through the slide bars, blocks, and levers to
the needle bar and shuttle carrier. All the required rests or pauses
for the shuttle and noedlo are produced by the radial arm acting
upon the eccentric strap in conjunction with the rotary motion of the
eccentric.
Secondly. The shuttle carrier is so arranged as to hold the shuttlo
firmly between its supports, releasing it only to allow the loop or thread
to pass round it, after which the shuttle is again held firmly until the
loop is required to pass round again. For this purpose one end of the
shuttle carrier is hinged, and by the action of a finger or arm actuated
by the movement of the shuttle bar holds the shuttle firmly and only
releases it at the required time for the loop to pass.
Thirdly. At the end of the needle bar carrying the needle we mount
a ring, through which we pass a pin or set screw. The pin or screw by
the turning of the ring comes in contact with a key fitted into a slot in
the needle bar, causing it thereby to tighten upon the needle, holding it
thereby firmly in any required position.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Altham Pilling and Arthur Nussey in the Great
Seal Patent Office on the 20th October 1871.
TO ALL TO WHOM THESE PRESENTS SHALL COME, wc, ALTHAM
PILLING and ARTHUR NUSSEY, both of Leeds, in the County of York, 3
send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Twentieth day of April, in the year of
our Lord One thousand eight hundred and seventy-one, in the thirty-

page_text: fourth year of Her reign, did, for Herself, Her heirs and successors,
give and grant unto us, the said Altham Pilling and Arthur Nussey,
Her special licence that we, the said Altham Pilling and Arthur Nussey,
our executors, administrators, and assigns, or such others as we, the
said Altham Pilling and Arthur Nussey, our 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,"
upon the condition (amongst others) that we, the said Altham Pilling
and Arthur Nussey, our executors or administrators, by an instrument
in writing under our, 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 Offico within six calendar months next and
immediately after the date of the said Letters Patent.
NOW KNOW YE, that we, the said Altham Pilling and Arthur Nussey,
do hereby declare the nature of our 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 accom-
panying Drawings, and to the letters of reference marked thereon, that
is to say:-
Firstly. The Invention relates to an arrangement for producing the
required motion to the needle bar and shuttle carrier.
Secondly. The construction of the shuttle.
Thirdly. The means employed for securing the needle in the needle
bar.
Firstly. On the driving shaft which is carried by the head we fix
an eccentric, on which is fitted an eccentric strap. On the eccentric
strap are mounted two pairs of brackets, which may be made adjustable
though not necessarily so. A slide bar is mounted and fixed between
each pair of brackets, on which are fitted slide blocks so as to slide
freely. The lever for transmitting motion to the needle bar is attached
to the upper slide block, and the lever for transmitting motion to the
shuttle carrier is attached to the lower slide block. On the head is
also mounted a radial arm which is connected or coupled to the eccentric
strap. By the eccentric being made to revolve motion is given to the

page_text: eccentric strap and transmitted through the slide bars, blocks, and levers
to the needle bar and shuttle carrier. All the required rests or pauses
for the shuttle and needle are produced by the radial arm acting
upon the eccentric strap in conjunction with the rotary motion of the
eccentric.
Secondly. The shuttle carrier is so arranged as to hold the shuttle
firmly between its supports, releasing it only to allow the loop or thread
to pass round it, after which the shuttle is again held firmly until the
loop is required to pass round again. For this purpose one end of the
shuttle carrier is hinged, and by the action of a finger or arm actuated
by the movement of the shuttle bar holds the shuttle firmly and only
releases it at the required time for the loop to pass.
Thirdly. At the end of the needle bar carrying the needle we mount
a ring, through which we pass a pin or set screw. The pin or screw by
the turning of the ring comes in contact with a key fitted into a slot in
the needle bar, causing it thereby to tighten upon the needle, holding it
thereby firmly in any required position.
And in order that our Invention may be more completely under-
stood we annex and proceed to describe the accompanying Sheet of
Drawings.
Figs. 1, 2, 3, 7, 10, and 11 illustrate the first part of our Invention;
Figs. 7, 8, and 9, the second part of our Invention; and Figs. 4, 5, and 6,
the third part of our Invention.
Firstly. On the driving shaft a which is carried by the head we fix
an eccentric c, on which is fitted an eccentric strap d. On the eccentric
strap two pairs of brackets are mounted e and, which may be made
adjustable though not necessarily so. The slide bars g and h are
mounted between the brackets e and, and fixed into them as shown.
On the slide bars g and the slide blocks i and j are fitted so as to slide
freely. The lever k for transmitting motion to the needle bar is attached
to the upper slide block i, and the lever for transmitting motion to
the shuttle carrier m is attached to the lower slide block j. On the head
is also mounted a radial arm n, which is connected or coupled to the
eccentric strap as shewn at o (Figs. 1, 2, and 3). By the eccentric c
being made to revolve motion is given to the strap d, and transınitted
through the slide bar g, block i, and lever to the needle bar k¹.
Motion is also transmitted from the same source through the slide bar h,
block, and lever to the shuttle carrier m.
All the rests or pauses

page_text: required for the shuttle and needle are produced by the radial arm n
acting upon the eccentric strap d in conjunction with the rotary motion
of the eccentric c.
In order more fully to describe the peculiar combination of mechanism
in the above-described arrangements we will refer to Fig. 7. In position 1
shewn in full lines the needle has descended and penetrated the material,
and the shuttle is ready for passing the loop. In position 2 shewn
thus,
the needle has risen and formed the loop,
and the shuttle is in the act of passing through it. Position 3, shewn
thus,
the needle has risen to the highest point, and
-
-
the shuttle has passed through and clear of the loop. Instead of the
eccentric a crank c constructed as shewn in Figs. 10 and 11 may be
used, on which the brackets e and fare mounted for carrying the slide
bars, these being of a similar construction to those shewn in Figs. 1,
2, 3, and 7.
and
Secondly. In the second part of our Invention the shuttle carrier m
is so arranged as to hold the shuttle firmly between its supports p q
(Figs. 7, 8, and 9), releasing it only to allow the loop or thread to pass
round it, after which the shuttle is held firmly until the loop is
required to pass round again, preventing the rattle usually attending
this movement. For this purpose the end support p of the shuttle
carrier is hinged or mounted on a stud 8 as shewn, and kept up to the
shuttle by a spring t. The outer support is either allowed to press or
hold the shuttle firmly in its bearings by means of the spring t, or by the
action of the lever on the incline u to release the outer support p when
required, thereby permitting the loop to pass. Fig. 7 shews the various
positions of the finger with respect to the outer support, and also the
position of the outer support with respect to the shuttle r.
Thirdly. Our Invention further consists in the construction of the
end of the needle bar for carrying the needle, and is shewn at Figs. 4, 5,
and 6. We fit on it a ring a, which for the sake of lightness may be
made of sheet steel joined at b, as shewn, forming a thumb piece. In
the ring a we fix the stud c. We provide a slot in the needle bar which
carries the needle and key. We recess the needle bar under the ring
in an eccentric form as shewn. It will be readily understood that by
turning the ring a by means of the thumb piece b the stud c comes
in contact with the eccentric portion of the recess, forcing thereby the

page_text: key d against the needle as shown, whereby the needle is held firmly in
position during the operation of sewing.
Having now described the nature of the said Invention, and the
manner in which the same is to be performed, we would remark in
conclusion that we do not limit ourselves to the exact details or con-
figuration of parts we have expressed and shewn, as the same may be
varied or modified without in any way departing from the nature or
principle of our Invention; but what we do claim and desire to be secured
to us by Letters Patent arc,—
Firstly. The arrangement, construction, and combination of parts
for imparting a properly timed motion to the needle bar and shuttle,
by means of a crank or eccentric c working in combination with a radial
arm », slide bars 9 and h, and blocks i and j, substantially as herein
set forth.
Secondly. The arrangement, construction, and combination of parts for:
giving motion to the shuttle carrier and for retaining the shuttle in the
manner described and for the purposes hercin set forth.
Thirdly. The method of holding the needle, substantially as and for
purposes herein set forth.
In witness whereof, we, the said Altham Pilling and Arthur Nussey,
have hereunto set our hands and seals, this Seventeenth day of
October, in the year of our Lord One thousand eight hundred and
seventy-one.
