Year: 1863

page_text: LETTERS PATENT to Thomas Markland, of Hyde, in the County of
Chester, and John Charles Dickinson, of Blackburn, in the County of
Lancaster, Machine Maker, for the Invention of "CERTAIN IMPROVE-
MENTS IN MACHINERY OR APPARATUS FOR WARPING OR BEAMING YARNS OR
Sealed the 15th August 1863, and dated the 19th February 1863.
PROVISIONAL SPECIFICATION left by the said Thomas Markland and
Charles Dickinson at the Office of the Commissioners of Patents, with
their Petition, on the 19th February 1863.
We, THOMAS MARKLAND, of Hyde; in the County of Chester, and JOHN
CHARLES DICKINSON, of Blackburn, in the County of Lancaster, Machine
Maker, do hereby declare the nature of the said Invention for "CERTAIN
IMPROVEMENTS IN MACHINERY OR APPARATUS FOR WARPING OR BEAMING YARNS
OR THREADS," to be as follows:-
Our Invention is designed for the purpose of stopping the mechanism
employed in the processes of warping and beaming when any of the threads
become disunited, and the improvements consist in a novel adaptation;
arrangement, and construction of apparatus for effecting the said purpose,
and which may be described as follows:-Between the ordinary rollers and
the warping beam a series of "dents" are arranged, which are secured in
elastic material so as to be contracted or expanded at requirement; these "dents"

page_text: are employed to serve as guides for fingers or levers under which the yarn
passes from the rollers to the beam, the said yarn in its progress passing
underneath a cranked or bent portion of the said levers or yarn guides, thus
keeping them by the tension of the yarn in an elevated position, but as soon
as one or more of the yarn threads become broken or disconnected the levers
or yarn guides resting upon such threads are released and fall upon the frame
holding the fulcra or centres of such levers and guides, thereby preventing
or stopping a reciprocating rod in connection with the stopping motion of
the machine from completing its action, and causing an instantaneous stoppage
of the whole machine. A "faller shaft," having a wire attached to a bell
crank lever, passes underneath the whole series of guides, which, when the
machine is stopped, raises such guides into position for the warp or yarn
passing under them in their progress to the warping mill.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Thomas Markland and John Charles Dickinson in the Great
Seal Patent Office on the 19th August 1863.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, THOMAS
MARKLAND, of Hyde, in the County of Chester, and JOHN CHARLES DICKINSON,
of Blackburn, in the County of Lancaster, Machine Maker, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Nineteenth day of February, in the year of our Lord
One thousand eight hundred and sixty-three, in the twenty-sixth year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto us, the
said Thomas Markland and John Charles Dickinson, Her special license, that
we, the said Thomas Markland and John Charles Dickinson, our executors,
administrators, and assigns, or such others as we, the said Thomas Markland
and John Charles Dickinson, 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 "CERTAIN
IMPROVEMENTS IN MACHINERY OR APPARATUS FOR WARPING OR BEAMING YARNS
OR THREADS," upon the condition (amongst others) that we, the said Thomas
Markland and John Charles Dickinson, our executors or administrators, by
an instrument in writing under our, or one of our, or their, or one of their

page_text: 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 I, the said Thomas Markland, do hereby declare
the nature of 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 Drawings (that is to say) :-
Our Invention is designed for the purpose of stopping the mechanism
employed in the processes of warping and beaming when any of the threads
become disunited, and the improvements consist in a novel adaptation;
arrangement, and construction of apparatus for effecting the said purpose,
and which may be described as follows:-Between the ordinary rollers and
the warping beam a series of "dents" are arranged, which are secured in
elastic material so as to be contracted or expanded at requirement; these dents
are employed to serve as guides for fingers or levers under which the yarn
passes from the rollers to the beam, the said yarn on its progress passing
underneath a cranked or bent portion of the said levers or yarn guides, thus
keeping them by the tension of the yarn in an elevated position, but as soon
as one or more of the yarn threads become broken or disconnected the levers
or yarn guides resting upon such threads are released, and fall upon the frame
holding the fulcra or centres of such levers and guides, thereby preventing or
stopping a reciprocating rod in connection with the stopping motion of the
machine from completing its action, causing an instantaneous stoppage to the
whole machine. A "faller shaft," having a wire attached to a bell-crank
lever, passes underneath the whole series of guides, which, when the machine
is stopped, raises such guides into position for the warp or yarn passing under
them in their progress to the warping mill.
In order that the Invention may be better understood and explained detail
we have hereunto attached a Sheet of Drawings, made upon a scale of about
two inches to the foot, similar letters of reference being marked upon cor-
responding parts of the apparatus.
Fig. 1 represents a sectional elevation of the apparatus; Fig. 2 is a front
view; Fig. 3 is an end elevation of the same, shewing the method of driving,
also the apparatus in connection therewith for disconnecting such driving
apparatus from the main driving pulley when any of the warp threads become
disunited; and Fig. 4 is a sectional view (shewn, about full size) of that
portion of the apparatus for stopping the machine, and which is in immediate

page_text: connection with the warp, such arrangement of apparatus therein shewn
constituting the chief feature of our Invention.
In the various Figures, a, a, are the standards or framing of the machine,
in which is secured the frame or supporter b, supplied with semicircular or
arch-shaped dents or guides c, secured and retained in position by means of
india-rubber or other elastic medium d; this elastic medium, being expanded
and contracted by the screw e, regulates the distance apart of the guides or
dents c, causing them to expand or contract; between each dent or guide is
placed a finger or lever f, situated between each guide, such finger hinging
loosely upon the fulcra or rod g, extending from end to end of the machine,
the yarn or warp on its passage from the rollers to the beam passes under-
neath a bent or cranked portion of the finger or lever f, at the point f, thus
keeping such finger by the tension of the yarn in an elevated, but when one
or more of the yarn threads become disconnected, the finger f, no longer
sustained in an elevated position by the yarn, immediately falls upon the frame
b, as shewn in red, and effects the stoppage of the machine by means of the
arrangement of mechanism herein-after described. In Fig. 3, h is the driving
shaft, which transmits motion through the friction pulley i to the large disc
or pulley j; the friction pulley i is so arranged that it can be adjusted upon
the driving shaft, bringing it nearer to or further from the centre of the disc j,
by this means any required speed may be given to the machine. The pulley k,
driven by the disc or pulley j, revolves loose upon the shaft, to this pulley k
is attached a sliding stud m pressing upon and resting in a hollow or recess
formed in the periphery of the small disc n, which is keyed upon the shaft ?;
the pulley k as it revolves drives the shaft 7, through the medium of the stud m
and disc n; upon the shaft are secured plates o, supplied with wires or
rods o¹, revolving with the shaft immediately underneath the framing b, so that
when one or more of the fingers or levers fall, or assume the position shewn
in red (Fig. 4), the rods or wires revolving with the shaft / come in contact
with such faller fingers, thereby stopping the revolution of the shaft / and
disc n, causing at the same time the stud m in the driving pulley k to rise out
of the recess in the disc n and come into contact with the cranked lever p, such
lever causing the release of the stop rod q, which is attached to the disc j, driven
by the friction wheel. When this contact takes place the stop rod q is released,
so that by means of the spring rit forces or slides back the disc j, causing such
disc to be drawn out of contact with the driving friction pulley i, and forced
against a brake fixed against the framing, which immediately effects the
stoppage of the machine; s is a rod beneath the fingers or levers f for simul-
taneously raising them when piecing the ends of the yarn or warp.

page_text: Having now described the nature of the said Invention, together with the
method of carrying the same into practical effect, we wish it to be distinctly
understood that we claim the arrangement, and construction, and adaptation of
the apparatus for effecting the stoppage of the mechanism employed in the
processes of warping and beaming when any of the threads become disunited,
as herein-before described, set forth, and fully illustrated in the Drawings
attached.
In witness whereof, I, the said Thomas Markland, have hereunto set
my hand and seal, this Eighteenth day of August, in the year of our
Lord One thousand eight hundred and sixty-three.
THOMAS MARKLAND. (L.S.)
