Year: 1875

page_text: LETTERS PATENT to Isaac Pickard, of Leeds, in the County of York,
for the Invention of "AN IMPROVED CASING OR COVERING FOR COPS OF
COTTON, SILK, OR OTHER THREADS TO BE USED ON SEWING MACHINES, OR FOR
HAND SEWING."
Sealed the 12th November 1875, and dated the 19th May 1875.

page_text: Secondly. To reduce the amount of threading up of shuttles, thus
saving time and producing greater regularity in the tension of the top
thread used in sewing machines, as well as the underneath thread used
in the shuttles of the same.
Thirdly. By adopting this Invention of casing or wrapper to dispense 5
with the wood and and other reels on which sewing cottons, silks, and
other threads are now wound, and used for hand or machine sewing.
Fourthly. By using this casing or wrapper or nearly so, the cop of
cotton, silk, or other thread, and drawing such thread from the inside,
there is less liability for the material to become soiled or wasted. The 1
casing or wrappor may be of any convenient form, varying of course
with the size of cop which it is intended to enclose, and is con-
structed of metal or its equivalent, which is first cut into the desired
shape, and folded round the cop in such a manner as to provent the
thread from being unwound from the outside, one or both ends of the 1
casing or wrapper being perforated or provided with a slot through which
the thread passes from inside of cop only.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Isaac Pickard in the Great Seal Patent Office
on the 19th November 1875.
TO ALL TO WHOM THESË PRESENTS SHALL COME, I, Isaac
PICKARD, of Leeds, in the County of York, send grecting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Nineteenth day of May, in the year
of our Lord One' thousand cight hundred and seventy-five, in the
thirty-eighth year of Her reign, did, for Herself, Her heirs and suc-
cessors, give and grant unto me, the said Isaac Pickard, Her special
licence, that I, the said Isaac Pickard, my executors, administrators,
and assigns, or such others as I, the said Isaac Pickard, 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
thorein 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 CASING

page_text: "
Firstly. To provide a casing or wrapper covering a cop of cotton, silk,
or other thread, dispensing with the ordinary method of rewinding spools
now used in shuttles of sewing machines.
Secondly. To reduce the amount of threading up of shuttles, thus
saving time and producing greater regularity in the tension of the top
thread used in sewing machines, as well as the underneath thread used
in the shuttles of the same.
Thirdly. By adopting this Invention of casing or wrapper to dispense
with the wood and other reels on which sewing cottons, silks, and other
threads are now wound and used for hand or machine sewing.
Fourthly. By using this casing or wrapper covering or nearly so the
‘cop” of cotton, silk, or other thread, and drawing such thread from the
inside, there is less liability for the material.to become soiled or wasted.
The casing or wrapper may be of any convenient form, varying of course
with the size of cop which it is intended to enclose, and is con-
structed of metal or its equivalent which is first cut into the desired
shape and folded round (placed on) the cop in such a manner as to
prevent the thread from being unwound from the outside; one or both
ends of the casing or wrapper being perforated, or provided with a slot
through which the thread passes from the inside of the cop only. .

page_text: And in order that my Invention may be more completely under-
stood, reference is given to the accompanying two Sheets of Drawings,
-and to the letters and figures marked thereon.
DESCRIPTION OF THE DRAWINGS.
Sheet 1 shews the construction of casing or envelope and its applica-
tion to cops of cotton, silk, or other thread, also the mode of applying
'the "
cops "enclosed in the aforesaid casings or envelopes in shuttles.
Sheet 2 shews the mode of applying the same to sewing machines in
lieu of the ordinary bobbin or reel.
.
The casing or envelope is constructed as shewn at Figures 1 and 2,
and also shewn at Figures 3, 4, and 5.
1 Firstly. I stamp or otherwise form the paper or its equivalent, as
shewn at Figure 1; through one or each of the projecting pieces a
and a¹ is provided a hole or slot b, the utility of which will be hereafter
described.
Previous to the cop being enclosed in the wrapper or envelope the
'casing or envelope is closed up into the form shewn at Figure 2, and
the parts secured together by any suitable material; the envelope or casing
having assumed this form it is ready for the reception of the "cop,"
and afterwards closed up, as shown at Figures 6 and 7, the projecting
end or flap a¹ is then turned over and caused to adhere in the manner
of an ordinary letter envelope which entirely encloses the cop..
Figures 8 and 9 shew cross sections of the casing or envelope with the
.cop enclosed.
In order to obtain an increased amount of tension I use an india-
rubber washer, as shewn at Figures 10 and 11, in which is provided a
slit c;
this washer is placed within the casing or envelope at one end of
the cop, as shewn at d, Figures 6 and 8. The end of the thread is
passed through the slit c and hole 6 from the centre of the cop. The
thread having been passed through the hole 6, as shewn at Figure 6, the
casing or envelope containing the cop is closed up ready for use.
When constructed of light thin sheet metal the plate is cut in the
shape shewn at Figure 3; through one or each of the projecting ends is
provided a hole or slot e. The casing or envelope being rolled up and
one end closed or leaving the end open for the. reception of the cop, a

page_text: the cop having been inserted and the thread or its equivalent passed
from the centre of the cop through the hole e the end fis closed up and
.the cop is ready for use.
When required, the friction washer similar to that shewn at Figures
10 and 11 may be applied.
The casings or envelopes with the cop enclosed are placed in the
shuttle, as shewn at Figures 12, 13, and 14, in which Figure 12 is an
-elevation; Figure 13, a longitudinal section; and Figure 14, a transverse
section through a, b, Figure 13. The thread is passed from the cop
through one hole of the shuttle, the necessary tension being obtained as
the material passes from the cop, the necessity of threading through
several holes being thus avoided; but when there is no washer o
employed in some cases the thread is required to be passed through
more than one hole of the shuttle.
Sheet 2 shews the mode of applying the herein-before mentioned
enclosed cop instead of the ordinary bobbin or reel; Figure 1 shews
the application of enclosed cop horizontally on the machine; Figure 2,
a plan; Figure 3, an elevation; and Figure 4, an end elevation of
carrier for enclosed cop when applied horizontally.
Figure 5 shews the application of enclosed cop in a vertical direction.
Figures 5, 6, and 7, shew respectively a side elevation, a front
elevation, and plan of carrier for enclosed cop when used vertically.
After the enclosed cop has been placed in the carrier, as shewn at a,
Figure 1, the thread is conducted to the needle'in the same manner as
when the ordinary bobbin or reel is used, or in many cases the present
general mode of tensioning may be dispensed with.
The herein-before mentioned enclosed cop may be also employed for
ordinary hand sewing purposes, taking up much less room than the
ordinary bobbin or reel. In using the enclosed coil for hand sewing,
one needleful at a time may be drawn off and cut near to the coil, the
remainder being kept clean and free from waste in the casing or
covering until it is required. The enclosed thread coils also take up
much less room than the wood and other reels which they are intended
to supersede.
The herein-before mentioned improvements may be applied to all

page_text: Having now declared the nature of my said Invention and shewn by
Drawings how the same may be carried into practice, I would have it
understood that I do not limit myself to the exact limits, details, or con-
figuration of the parts I have explained and shewn, as the same may
of course be varied or modified without in any way departing from my
Invention, but what I do claim and desire to be secured to me by Letters
Patent is,
Firstly. The arrangement, construction, and application of an
envelope or casing formed of paper, metal, or other equivalent material
or fabric for the reception of cops of cotton, silk, or other thread, sub-
stantially as and for purposes herein set forth.
Secondly. The arrangement, construction, and combination of the
various parts forming the means employed for imparting the required
tension to the cotton, silk, or other thread, substantially as herein set
forth.
In witness whereof, I, the said Isaac Pickard, have hereunto
set my hand and seal, this Eleventh day of November, in the
year of our Lord One thousand eight hundred and seventy-
five.
