Year: 1869

page_text: LETTERS PATENT to Colin Mather and William Rossetter, of Salford,
in the County of Lancaster, for the Invention of "IMPROVEMENTS
IN WARPING OR BEAMING MACHINES."
Sealed the 1st April 1870, and dated the 4th October 1869.
PROVISIONAL SPECIFICATION left by the said Colin Mather and
William Rossetter at the Office of the Commissioners of Patents,
with their Petition, on the 4th October 1869.
We, COLIN MATHER and WILLIAM ROSSETTER, of Salford, in the
County of Lancaster, do hereby declare the nature of the said Invention
for "IMPROVEMENTS IN WARPING OR BEAMING MACHINES," to be as follows:-
This Invention relates to warping or beaming machines having self-
acting stopping motions for stopping the machine when there is breakage
or absence of one or more warp threads. In these machines the warp
threads pass through eyes in stop pins or arms, and when the threads
are entire they support the pins or arms, but when a thread is broken
or absent its corresponding stop pin or arm drops and stops the move-
ment of reciprocating or oscillating bars and leads to the stoppage of the
machine.

page_text: Our Invention consists in improved stop pins and modes of carrying
them, and also in improved forms or arrangements of stop arms, which
improvements will be clearly understood by the following description
thereof, reference being had to the Figures on the accompanying two
Sheets of outline Drawings, in which Figs. 1 and 2 are side and front
views of part of reciprocating bars in connection with one arrangement
of our improved stop pins carried on flat bars. Figs. 3 and 4 are front
and side views of one of the pins.
Figs. 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, and 20 are
views of other forms or arrangements of stop pins.
Fig. 21 is a view of another mode of carrying the pins, and Figs.
22 and 23 are side and front views of one of our improved stop arms.
To make one of our improved stop pins a, Figs. 1, 2, 3, and 4, we
take a piece of flat steel wire, or sheet steel, or other rolled or hammered
metal and bend or shape it as shewn, and then punch at the upper part
a hole 6 and slot c, the hole being used as an eye for the warp thread to
pass through, and the slot for enabling the operative to thread the eye
without the use of a reed hook. Or the eye may be made without the
slot and a reed hook used if desired. The pins are threaded on flat
bars d, Figs. 1 and 2, extending across the machine and held fast to the
side frames, and the lower ends of the pins form the projections for
arresting the motion of reciprocating or oscillating bars when there is
breakage or absence of thread. Or the pins are placed on the bars by
opening them at the bottom and passing them over the bars, after
which the two sides of their lower ends spring together by their own
elasticity, and it will be seen that though the space in each pin is of such
length that the pin can move up and down the pin itself cannot be
jerked or shifted out of its place by the action of the thread, and thus
there is no possibility of the operative neglecting to piece the broken
ends and making bad work.
We also form holes in the sides of the stop pins to be used as eyes,
the holes being in such positions that the threads will be a little above.
the tops of the bars d, Figs. 1 and 2, for the purpose of causing the
fluke to be continuously cleared away. One of these pins is shewn in
Figs. 5 and 6, and the holes, are either slotted, or not as desired. The
stop pins when made of steel are hardened, and tempered if required,
and when made of sheet brass or other metal they must be as hard and
elastic as possible.

wire, and one form is shewn in Figs. 7 and 8, f being the
part passed over the bars.
eye, and
g the
Another form of pin similar to those shewn in Figs. 1, 2, 3, and 4,
but made out of round wire, is shewn in Figs. 9 and 10, h being the
eye, and k the part which passes over the bars.
Another form is shewn in Figs. 11 and 12, / being the eye and m the
part passed over the bars; and Figs. 13, 14, 15, 16, 17, 18, 19, and 20
are views of other forms of stop pins. All these stop pins made of
either flat or round wire may be curved or square at the bottom where
they arrest the motion of the reciprocating or oscillating bars, and as all
the pins are closed at the bottom they cannot be jerked off the bars d
by the action of the threads. The bars d are fixed to the side frames of
the machine in any desired manner, but one mode we adopt is to fix to
one end of each bar a screw, which is passed through a hole in a metal
plate held to the side frame, and the other end of each bar is passed
through a slot in another metal plate on the side frame at that end and
held by a pin, after which nuts are placed on the screws and all screwed
up tight. The bars may be made square if desired, and in all cases one
or more steadying plates are used as required.
We also use two or more strong wires extending across the machine
for carrying the spring stop pins, the wires being held by screws and
nuts to metal plates held to the side frames, and having one or more
steadying plates for each set of wires to keep them steady. In Fig. 21
we shew a stop pin on two round wires, but the wires may be rectangular
if desired.
Our improved stop arms are also made out of flat wire, or sheet metal,
or round wire, but we make the part which passes over the supporting
wire of an oblong shape instead of perfectly round as at present.
One of our improved flat wire arms is shewn in Figs. 22 and 23, in
which 9 represents the part which passes over the supporting wire; r, the
eye for the thread to pass through; and 8, the projection for arresting
the movement of reciprocating or oscillating bars when there is breakage
or absence of thread.

filed by the said Colin Mather and William Rossetter in the Great
Seal Patent Office on the 4th April 1870.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, COLIN
MATHER and WILLIAM ROSSETTER, of Salford, in the County of Lancaster,
send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Fourth day of October, in the year of our
Lord One thousand eight hundred and sixty-nine, in the thirty-third
year of Her reign, did, for Herself, Her heirs and successors, give and
grant unto us, the said Colin Mather and William Rossetter, Her special
licence that we, the said Colin Mather and William Rossetter, our
executors, administrators, and assigns, or such others as we, the said Colin
Mather and William Rossetter, 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 law-
fully 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 WARPING OR BEAKING MACHINES," upon
the condition (amongst others) that we, the said Colin Mather and
William Rossetter, 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 Office within six calendar months
next and immediately after the date of the said Letters Patent. .
NOW KNOW YE, that we, the said Colin Mather and William
Rossetter, 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 (that is to say):
=
This Invention relates to warping or beaming machines having self-
acting stopping motions for stopping the machine when there is breakage
or absence of one or more warp threads. In these machines the warp
threads pass through eyes in stop pins or arms, and when the threads
are entire they support the pins or arms, but when a thread is broken
or absent its corresponding stop pin or arm drops and stops the move-

page_text: ment of reciprocating or oscillating bars and leads to the stoppage of
the machine.
Our Invention consists in various improved forms of stop pins in
combination with the bars or wires on which they are placed, and also
in improved positions of the pins in relation to the said bars or wires,
and the manner in which the Invention is to be performed will be clearly
understood by the following particular description thereof, reference
being had to the figures and letters on the accompanying Sheet of
Drawings, in which Figures 1 and 2 are front and side views of part of
reciprocating bars in connection with one arrangement of our improved
stop pins carried on flat bars; Figures 3 and 4 are side and front views
of one of the pins detached; and Figures 5, 6, 7, 8, 9, 10, 11, 12, 13,
14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, and 31,
are views of other forms or arrangements of our improved stop pins.
In Figures 1 and 2, a represents part of the reciprocating bars; b the
ordinary oscillating shaft; c, one of the levers for working the bars;
d, the stop pins; and e, flat bars on which the pins are placed. To
make the stop pins d, Figures 1, 2, 3, and 4, we take for each a piece of
flat steel wire or sheet steel or other rolled or hammered metal and bend
or shape it, as shewn, and then punch at the upper part a holo f and
slot 9, the hole being used as an eye for the warp thread to pass through,
and the slot for enabling the operative to thread the eye without the
use of a reed hook. The flat bars e, Figures 1 and 2, on which the pins
are placed extend across the machine and are held fast to the side
frames, and the lower ends h of the pins form the projections for
arresting the motion of the reciprocating or oscillating bars when there
is breakage or absence of thread, and it will be seen that though the
space in each pin is of such length that the pin can move up and down
the pin itself cannot be jerked off or shifted out of its place by the
action of the thread, and thus there is no possibility of the operative
neglecting to piece the broken ends and making bad work, and to
prevent the pins from falling too low if the threads are slack and causing
the stoppage of the machine we employ wires i, Figures 1 and 2, for
the threads to rest upon and support the pins.
We also form holes in the sides of the flat wire or sheet steel stop
pins to be used as eyes, the holes being in such positions that the threads
will be a little above or in contact with the tops of the bars for enabling
the fluke to be continuously cleared away, and as there is an eye at each

page_text: side of the bar the thread if slack is prevented from falling so low as
to cause the pin to come in contact with the reciprocating. or oscillating
bar.
One of these pins is represented in the side and front views, Figures 5
and 6, and the holes may be slotted, as shewn, or the slots dispensed
with.
The simplest form of stop pin made of flat wire or sheet metal is
shewn in the side and front views, Figs. 7 and 8, and although it
cannot be so conveniently handled as that shewn in Figs. 5 and 6 it
may in some cases be found advantageous to use it.
We also form stop pins to be carried by the bars e out of round wire,
'and one form is shewn in the side and front views, Figures 9 and 10,
k being the part used as an eye for the warp thread to pass through;
1, the part passed over the bar; m, the projecting end for arresting the
motion of the reciprocating or oscillating bars when there is breakage
or absence of thread; and n, a ring at the top for enabling the pin to
be easily handled, but when desired we make this description of stop
pin without the ring, as shewn in the side and front views, Figures
11 and 12.
Another of our improved stop pins made of round wire and having
two parts one at each side of the bar resting on the thread when entire,
is shewn in the side and front views, Figures 13 and 14, o being the parts
resting on the thread; p, the part passed over the bar; and 9, the
arresting end; and Figures 15 and 16 are views of a similar pin, with
the addition of a part projecting upwards for the convenience of
handling.
Figures 17 and 18 are side and front views of a stop pin with two resting
parts, but open at the bottom for enabling the pins to be taken off and
placed on the bars when rows of different colored warp threads are to
be beamed.
Other forms of stop pins adapted for passing over the bars e, Figures
1 and 2, are shewn in Figures 19, 20, 21, 22, 23, 24, 25, and 26, & being
the part resting on the thread when it is entire; t, the part passed over
the bar; and u, the end for coming in contact with the reciprocating
or oscillating bar when there is breakage or absence of thread, and all a
the stop pins may be curved or square at the top and bottom.

page_text: We also make stop pins having two parts for resting on the thread
and open at the top where they are passed over the bars, and employ a
wire for preventing them from falling too low, and Figures 27 and 28
are side and front views of a stop pin formed according to this arrange-
ment, being the parts resting on the thread; w, the part passed over
the bar; x, the end which arrests the reciprocating or oscillating bar
when required; and y, a projecting part which rests on the wire z when
the pin falls.
In another arrangement of stop pin open at the top and also having
two parts resting on the thread one at each side of the bar, we form
the bar with a projecting ridge and bend the pin to suit, as shewn
in the side and front views, Figures 29 and 30, in which a' represents
the parts of the pin resting on the thread; b', the part passed over the
bar; c, the projecting ridge; and d, the bent part of the pin for
preventing it from falling too low. The bars on which the stop pins
are placed are held vertically or slightly angular to the side frames of
the machine in any 'desired manner, but one mode we adopt is to fix
to one end of each bar a screw, which is passed through a hole in a metal
plate held to one side frame, and the other end of each bar is passed
through a slot in a plate on the other side frame and held by a pin,
after which nuts are placed on the screws and all screwed up tight, and
steadying plates having notches passed over the bars are used as
required.
We also use two or more wires for carrying the stop pins, the wires
being fixed by screws and nuts to metal plates held to the side frames
and having one or more steadying plates for each set of wires to keep
them rigid. In Figure 31 we shew a stop pin on two round wires e',
but the wires may be rectangular if desired. With the improved stop pins
shewn in Figures 1, 2, 3, 4, 19, 20, 21, 22, 23, 24, 25, and 26, in each
of which the single eye or part which rests on the thread is considerably
above the top of the bar when the thread is entire, we employ two
wires, as shewn in Figures 1 and 2, for preventing the pin from falling too
low when the thread is slack, but when the single eye is on one side
near the top of the bar or near the top of the upper wire, Figure 31, a
single wire on the opposite side of the bar or in front of the eye or
bearing for the threads is sufficient, and when there are two eyes or parts
for resting on the threads at each side of the bar as in the pins shewn in
Figures 5, 6, 7, 8, 13, 14, 15, 16, 17, 18, 27, 28, 29, and 30, the extra
wires are dispensed with, as the thread supports the pin at each side of

page_text: the bar, so that as the thread travels onwards to be wound on the beam
the fluke is continuously cleared away from the narrow surface of the
bar, and as the thread is so close to the bar the pin is prevented from
falling so low as to come in contact with the reciprocating or oscillating
bar or bars if the thread should happen to be too slack, and this
peculiarity of the double eyes or parts of each pin resting on the thread
in close proximity to the top of the bar or its equivalent forms one of
the main features of our Invention.
Having now described the nature and particulars of our said Invention,
and the manner in which the same is to be performed, we desire it to
be understood that in warping or beaming machines having self-stopping
motions we claim, the improved forms or arrangements of stop pins in
combination with the bars or wires on which they are placed, and also
the system of placing the double eyes or parts resting on the threads in
close proximity with the tops of the bars or wires, as all such improve-
ments are herein described and illustrated in the accompanying Slicet of
Drawings.
In witness whereof, we, the said Colin Mather and William
Rossetter, have hereunto set our hands and seals, this First day
of April, in the year of our Lord One thousand eight hundred
and seventy.
