Year: 1873

page_text: LETTERS PATENT to Charles Parkinson, of Accrington, in the County
of Lancaster, Manager, for the Invention of "IMPROVEMENTS IN
MACHINERY FOR BEAMING OR WARPING YARN."
Sealed the 19th September 1873, and dated the 22nd March 1873.
PROVISIONAL SPECIFICATION left by the said Charles Parkinson
at the Office of the Commissioners of Patents, with his Petition, on
the 22nd March 1873.
I, CHARLES PARKINSON, of Accrington, in the County of Lancaster,
3 Manager, do hereby declare the nature of the said Invention for “Ix-
PROVEMENTS IN MACHINERY FOR BEAMING OR WARPING YARN," to be as
follows:-
This Invention relates to machinery for purposes as above, and the
object is to stop the machine when an "end" or thread breaks.
I employ a cross shaft, to which are secured two vertical arms, and
these carry a cross bar or "feeler" working "to and fro" under
a grating or bar having slits or passages therethrough. To one end of

page_text: "
the "feeler is secured two catches or hooks, which are carried "to
and fro" by the motion of the "feeler" immediately over or under a
notched horizontal bar. A notch in the side of the latter bar holds a
vertical lever (connected to the boss of the friction pulley and plate) in
position. A partial rotary motion is imparted to the cross shaft carrying
the vertical arms and "feeler by means of a disc, stud, and link on
the driving shaft, the other end of this link is attached to the joints of
two other links, one working from a fixed centre or stud, the other end
of the third link being attached to an arm fixed on the cross shaft,
to which by means of the links they impart four partial rotations of
the cross shaft and motions to the "feeler" bar for each rotation of
the disc.
ch
The operation of the machine is as follows:-Each "end" or warp
thread is passed through eyelets, the lower portion of each eyelet so long
as the threads are in continuity or unbroken is suspended in or projecting
slightly through the openings or slits in the grating, and the oscillating
" feeler" is free to pass "to" and "fro" under the same; on an end or
thread breaking its eyelet at once drops lower, projecting further through
the slit or grate bar, and the "feeler" at once comes in contact with the
eyelet, the "feeler" is thereby turned on its end bearings, and one of
the catches is depressed and engages with a notch in the horizontal bar
herein, 'referred to, sliding the same endways, and so knocking off the
lever connected with the friction driving apparatus. The notched
horizontal bar resumes its position for holding the lever through the
agency of a weight and cord passed over pulleys, the "fecler" bar
adjusts itself by gravitation, and is held by means of a curved spring
and pin in position until again acted on by a falling eyelet.

page_text: year of our Lord One thousand eight hundred and seventy-three, in the
thirty-sixth year of Her reign, did, for Herself, Her heirs and successors,
give and grant unto me, the said Charles Parkinson, Her special licence
that I, the said Charles Parkinson, my executors, administrators, and
assigns, or such others as I, the said Charles Parkinson, 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
Islands, and Isle of Man, an Invention for “ Improvements in MACHINERY
FOR BEAMING OR WARPING YARN," upon the condition (amongst others) that
I, the said Charles Parkinson, my executor's 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 Scal Patent Office within six
calendar months next and immediately after the date of the said Letters
Patent.
NOW KNOW YE, that I, the said Charles Parkinson, 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 and accompanying Sheets of Drawings, that
is to say :-
This Invention relates to machinery for purpose as above and the
object is to stop the machine when an end or thread breaks.
I employ a cross shaft, to which are secured two vertical arms, and
these carry a cross bar or "feeler" working to and fro under a grating
or bar having slits or passages therethrough. To one end of the "fecler"
are secured two catches or hooks, which are carried to and fro by the
motion of the "feeler" immediately over or under a notched horizontal
bar. A notch in the side of the latter bar holds a vertical lever (connected
to the boss of the friction pulley and plate) in position.
The operation of the machine is as follows:-Each end or warp thread
is passed through eyelets, the lower portion of each eyelet so long as the
threads are in continuity or unbroken is suspended in or projecting
slightly through the openings or slits in the grating, and the oscillating
"fecler" is free to pass to and fro under the same; on an end or thread

page_text: breaking its eyelet at once drops lower, projecting further through the
slit or grate bar, and the "feeler" at once comes in contact with the
eyelet, the "feeler "is thereby turned on its end bearings, and one of the
catches is depressed and engages with a notch in the horizontal bar
herein referred to, sliding the same endways, and so knocking off the lever 5
connected with the friction driving apparatus. The notched horizontal
bar resumes its position for holding the lover, through the agency of a
weight and cord passed over pulleys, the "feeler bar" adjusts itself by
gravitation, and is held by means of a curved spring and pin in position
until again acted on by a falling eyelet.
In order that my said Invention may be clearly understood I have
hereunto annexed two Sheets of Drawings, and have marked the samo
with figures and letters of reference.
Fig. 1 is an end view of a machine for purpose above referred to and
having my improvements attached; Fig. 2 is a front view; Fig. 3 shews
the parts detached, and Figs. 4 and 5 are details enlarged of the "feeler
bar," grating, and eyelets.
A is the cross shaft (or studs may be employed) on which the vertical
arms B, B, are mounted and work, these arms carry the cross bar or
" feeler" C to and fro (by means hercin-after described) under the grating
or bar D. The pivots E and E¹ of the “feeler-bar" work in the brackets
F, F, attached to the arms B, B, and on the end of E¹ are mounted the
two catches or hooks H, H, which are carried to and fro immediately over
the notched horizontal bar J, this bar has a notch or recess K, formed
therein in which the end of the stop rod L rests so long as the threads
are in continuity or unbroken. The to and fro motion is imparted to
the arms B, B, by the tappet M on the driving shaft N acting on the
bowl N', the latter being mounted on the end of the curved arm or lever
P attached to the arm B.
The operation of the machine is as follows:- -Each end or warp thread
P¹ is passed through cyclets R, the lower portion of each eyelet so long
as the threads are in continuity or unbroken is suspended in or projecting
slightly through the openings or slits in the grating S, and the oscillating
"feeler" C passes to and fro under the same, on an end or thread break-
ing its eyelet at once drops lower, projecting further through the slit or
grate bar, and the "feeler bar" during either stroke at once comes in
contact with the fallen eyelet, the "feelor" is thereby turned on its end
pivots and one of the catches H is depressed and engages with one of the
1

page_text: notches in the horizontal bar J, sliding the same endways, and so
knocking off the lever or stop rod L connected with the friction driving
apparatus by causing the said rod to ascend one of the inclined sides of
the recess K formed in the notched bar J, so turning or moving the said
rod outward and disengaging the catch for throwing out the driving
apparatus. The bar J resumes its position for holding the lever L
through the agency of a weight T and a cord passed over the pulleys
W, the "fecler bar" adjusts itself by gravitation, and is held by means
of the curved spring Y in position until again acted on by a falling
eyelet.
Having thus fully described the nature and particulars of this my
Invention, I would have it understood that I claim-
Firstly. The application and use of the catches or hooks operated by
mcans of the cross bar or "feeler" and arms B, B, as and for the purpose
herein fully described and illustrated.
Secondly. The notched bar J, as and for the purpose herein fully
described and illustrated.
Thirdly. The combination and arrangement of the several parts com-
prising the swivel cross bar or "fceler," the catches or hooks, and the
notched bar, as and for the purpose herein fully set forth and shown in
the Drawings.
In witness whereof, I, the said Charles Parkinson, have hereunto
set my hand and scal, this Seventeenth day of September, in the
year of our Lord One thousand eight hundred and seventy-three.
