Year: 1867

page_text: Pilling, and Frederick Jennings at the Office of the Commissioners of
Patents, with their Petition, on the 13th August 1867.
We, GEORGE PILLING and JOHN PILLING, of Halifax, in the County of
York, Dyers, and FREDERICK JENNINGS, of the same Place, Mechanic, do
"IMPROVEMENTS IN
hereby declare the nature of the said Invention for
MACHINERY FOR SAVING OR COVERING THE LISTS OR EDGES OF FABRICS," to be
as follows:-
This invention relates to machinery or apparatus for placing and securing
a web of closely woven material over each list or edge of fabrics to be dyed
along with the fabric, and technically known as "saving."
Our improvements consist in a new combination and arrangement of
mechanical parts for folding the said lists either into rolls or upon cords and
placing the web or webs in position and sewing it thereon; also drawing or
propelling the fabric forward intermittently. An ordinary frame or table is
employed on which is supported a rotary shaft which may receive motion by
hand or power. A groove is formed across the table, and a folding instrument
1

page_text: is attached which is constructed of two tongues or strips of metal twisted
spirally, leaving a space betwixt them for the list to pass through. A series
of guides or curved plates are also attached to guide the web and cord (when
used) into proper position, and a pair of finted rollers are employed to draw
or propel the fabric forward under operation, which receives intermittent motion
by ratchet wheel and pawl from either cam, eccentric, or crank fixed on the
rotary shaft. We employ a circular or curved needle mounted on a spindle
to which oscillatory rotary motion is given by eccentric, cam, or crank on the
rotary shaft and rod operating a toothed segment wheel in gear with a pinion
on the said spindle; also a looper or instrument for taking into the loop of a
thread formed by the needle after its passage through the fabric is hinged
so as to be operated by a lever and rod attached to an eccentric, cam, groove,
or crank fixed on the rotary shaft, which taking into the thread forms a loop
and carries it over the edge of the fabric or transfers it to a suitable position
for the needle to pass through on its next insertion. And in some cases a
pusher is used to assist the looper in taking into the thread, which is also
operated by a cam, eccentric, or crank on the rotary shaft. Also we employ
brushes or pads to retain the loop thereon until the proper time of delivery to
the needle; and a pulley with an adjustable finger is fixed on the rotary shaft
for taking off a suitable quantity of thread from the supply bobbin at each
revolution or stroke of the needle.

Frederick Jennings, do hereby declare the nature of the 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 and accompanying
Sheets of Drawings (that is to say):--
This Invention relates to machinery or apparatus for placing and securing
a web of closely woven material over each list or edge of fabrics to be dyed
along with the fabric, and technically known as "saving."
Our improvements consist in a new combination and arrangement of
mechanical parts for folding the said lists either into rolls or upon cords and

is employed on which is supported a rotary shaft which may receive motion
by hand or power. A groove. is formed across the table, and a folding instru-
ment is attached which is constructed of two tongues or strips of metal twisted
spirally, leaving a space betwixt them for the list to pass through. .A series
of guides or curved plates are also attached to guide the web and cord (when

by ratchet wheel and pawl from either cam, eccentric, or crank fixed on the
rotary shaft. We employ a circular or curved needle mounted on a spindle
to which oscillatory rotary motion is given by eccentric, cam, or crank on the
rotary shaft and rod operating a toothed segment wheel in gear with a pinion
on the said spindle; also a looper or instrument for taking into the loop of a
thread formed by the needle after its passage through the fabric is hinged so
as to be operated by a lever and rod attached to an eccentric cam, groove, or
crank fixed on the rotary shaft, which taking into the thread forms a loop

page_text: and transfers it to a suitable position for the needle to pass through on its
next insertion. In some cases a pusher is used to assist the looper in taking
into the thread, which is also operated by a cam, eccentric, or crank on the
rotary shaft. And a pulley with an adjustable finger is fixed on the rotary
shaft for taking off a suitable quantity of thread from the supply bobbin at
cach revolution or stroke of the needle
DESCRIPTION OF DRAWINGS.
In order that this Invention may be clearly understood we have herein
given reference to two Sheets of Drawings of a machine constructed in
accordance therewith, wherein Fig. 1 represents the plan or top view, Fig. 2
a longitudinal and vertical section, Fig. 3 a cross section, and Fig. 4 is the
underneath view of same.
A is the rotary shaft with both hand wheel A 1 and grooved pulley A 2 to
enable the machine to be turned by either hand or power: this shaft. is
mounted in bearings A 3 underneath the table B. A groove is cut. or. formed
across the top side of the table at B 1, and a folding instrument C is fixed
upon the table immediately over one end of the said groove; this instrument
is composed of a pair of tongues or strips of metal twisted so as to leave a
spirally formed space betwixt them at a suitable distance apart according to the
thickness of the fabric, the list of which is caused to pass through this space
when the twisting thereof turns the said list into a fold or roll. When a
cord is required to be introduced within the rolled list it is passed through a
guide eye D, as shown, and the web required to be folded or wrapped around
the rolled list is passed through a guide eye E, thence over the guide eye D,
and under the curved guide F, which places it in proper position, enclosing
the list of the fabric, both of which are thence passed forward under the
guide F1 to the fluted rollers G and G 1, which having intermittent rotary
motion given them propel or draw the fabric forward through the machine
intermittently, while the circular or curved needle H is caused to pass around
the roll, and be inserted and passed through the fabric at the inner edge of
the said roll, carrying thread or cord with it, which on the return of the needle
is seized by a looper I and held in suitable position in a loop until the next
insertion of the needle, which passes through the loop in the usual manner of
chain-stitch sewing, the needle again carrying the thread or cord around the
roll and passing it through the fabric, when it is again seized by the looper
and held as before, and so on. Intermittent motion is communicated to the
fluted rollers by a catch or pawl J attached to a lever J 1 hinged on a stud
at J 2, and operated in one direction by a cam J 3 fixed on the rotary shaft A,

page_text: and in the other by a spiral spring J 4; this catch acts upon a ratchet wheel K
fixed on the shaft K1 which carries the roller G. Oscillatory rotary motion
is given to the needle by an eccentric L fixed on the shaft A, which by rod L 1
operates a segment wheel or lever L 2, the segment end being toothed and
Motion is
gearing with a tooth pinion fixed on the axis of the needle H.
given to the looper by an eccentric M fixed on the shaft A operating a rod M 1
which is attached to a bell-crank lever M 2 (hinged to the table), to the other
arm M 3 of which is fixed the looper I. To assist the looper in seizing the
thread a pusher P is used which is hinged under the table at P 1 and operated
by a cam R fixed on the shaft A in one direction, and in the other by a
spring S. In order to avoid strain upon the needle or on the thread guide T
we employ a pulley U which is fixed on the rotary shaft, and which is formed
of two discs with an adjustable finger or gauge piece U 1 betwixt them; by
setting this gauge nearer to or further from the shaft the proper quantity of
thread required at each stroke or stitch is taken from the supply bobbin and
delivered to the needle. The top fluted roller G is mounted upon an eccentric
shaft to which is attached a handle G 2 by the movement of which this roller
may readily be removed from contact with the other or the fabric passing
betwixt them, and an ordinary adjusting screw G 3 is used for setting the rollers
at a suitable distance apart.
In witness whereof I, the said John Pilling, for and on behalf of myself
and the said George Pilling and Frederick Jennings, have hereunto
-set my hand and seal, this Twelfth day of February, One thousand
eight hundred and sixty-eight.
JOHN PILLING. (L.S.)
