IMPROVEMENTS IN MACHINERY OR APPARATUS FOR WARPING YARNS
Year: 1856

page_text: LETTERS PATENT to Samuel Clegg and John Kay, of Padiham, near
Burnley, in the County of Lancaster, Warpers, for the Invention of
PROVISIONAL SPECIFICATION left by the said Samuel Clegg and John
Kay at the Office of the Commissioners of Patents, with their Petition,
on the 5th March 1856.
We, SAMUEL CLEGG and JOHN KAY, of Padiham, near Burnley, in the
County of Lancaster, Warpers, do hereby declare the nature of the said
Invention, for "IMPROVEMENTS IN MACHINERY OR APPARATUS FOR WARPING YARNS,"
to be as follows:-
Our Invention relates to that part of the warping apparatus between the
reel and the mill, or that part which guides the warp threads to the mill, and
consists of arranging it so that the threads of the warp shall be perfectly
separated in the form of a shed, by which the leash is easily made without the
trouble of separating the threads by hand. We make the sword to slide in
slots, so that it is easily drawn from between the threads and replaced to form
another shed; each alternate thread passes under and over the sword, then
over the guide bar and through the rack to the mill, but between the said
rack and the mill they are kept separate by means of a double projector or

page_text: bobbin with two circular grooves, one-half the threads being guided by one
groove and the other half by the other groove, thus facilitating the operation of
leashing.
Our said Invention will be easily understood by reference to the accoun-
panying outline Drawings, in which a represents a sliding bar, to which
is attached the sword b. The said bar and sword slides in the slots c for the
purpose of drawing the sword from the shed, which is formed by each alternate
thread passing under and over the said sword. d is the guide bar over which
all the threads pass; close to which is the half bear lease e, over which
the threads also pass to and through the rack f to the double projector 7 or
bobbin, with two circular grooves, keeping the threads separate to facilitate
the leashing operation.
SPECIFICATION in pursuance of the conditions. of the Letters Patent, filed
by the said Samuel Clegg and John Kay in the Great Seal Patent Office
on the 4th September 1856.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, SAMUEL
CLEGG and JOHN KAY, of Padiham, near Burnley, in the County of Lancaster,
Warpers, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Royal
Letters Patent, bearing date the Fifth day of March, in the year of our
Lord One thousand eight hundred and fifty-six, in the nineteenth year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto us, the
said Samuel Clegg and John Kay, Her special licence that we, the said Samuel
Clegg and John Kay, our executors, administrators, and assigns, or such others
as we, the said Samuel Clegg and John Kay, 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
***IMPROVEMENTS IN MACHINERY OR APPARATUS. POR WARPING YARNS," upon the
condition (amongst others) that we, the said Samuel Clegg and John Kay,
by an instrument in writing under our hands. and seals, or under the hand
and seal of one of us, 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 Royal Letters
l'atent.

page_text: NOW KNOW YE, that we, the said Samuel Clegg and John Kay, 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 (that is to say):-
2;
Our Invention relates to that part of the warping, apparatus between the
heck and the mill, or that part which guides the warp threads. to, the mill, and
consists of arranging it so that the said threads shall be perfectly separated' in
the form of a shed. We attach to a slide rod and parallel with it a sword
or bar of any desired shape, and placed so that the threads from the heck pass
over and under it alternately, and then through a lift or lifts, for the more
effectual collection of the half beers at the foot lease. By lifting one of the
alternate lifts of the heck it produces a shed; which is preserved by pulling
the slide rod, thereby drawing the sword into the shed; the heck lift being
then let down, the shed is retained by the sword, and. then passes through the
half beer lifts in portions; from the lift or lifts, the threads. pass onwards to
a double projection pulley, having a central flange, or a pulley with one flange,
for the purpose of keeping the shed still open, and maintaining it the same as
at the sword, in two portions; one, the upper part of the shed; and the other
the lower, thereby preventing the lease from closing as it passes to the warping
mill. The above arrangement renders half beers unnecessary. These im-
provements will be clearly understood by reference to the accompanying
Sheet of Drawings with the figures and letters of reference thereon, the said
letters referring to similar parts in the different views.
Fig. 1 is a front elevation of our improved machine or apparatus; Fig. 2 is
a plan; and Fig. 3, an end view thereof. Fig. 4 shews part of the lift when
half is raised. Fig. 5 represents the double projection pulley ;"and Fig. 6, a
modification of the same. a represents the main frame of the machine; b, the
slotted standards, into which is fitted the slide rod c, having at one end the
knob or handle d, and at the other the frame or support e, for the sword or
bar f, over and under which the threads 9 from the heck are made to pass,
the slide rod enabling the sword to be readily drawn from the shed and
replaced when another is formed. The threads pass-through the lifts h, the
spindles of which are guided by the bar i, and supported at the bottom by
the two bars and 7, one half in each. The bars and lifts are raised when
required by means of the rods m acting on the cranks n and upright rods o,
which are connected to the bars k and l.
the double projection pulley p, placed on a spindle in the support Q, attached
to the main frame a. One half of the threads pass over the upper part of the
flange * and the other half below it, thus preserving the lease from closing as
From the lifts the threads pass to

page_text: it passes to the warping mill. The projection pulley p. is shewn enlarged a
Fig. 5. The flanges s are simply for the purpose of preventing the spreading
of the threads. Other forms of projections may be employed provided the
separating or dividing flange be maintained, the spreading of the threads being
prevented by the taper form above the flange, as shewn in Fig. 6, or by
separate surfaces against which the threads touch in their passage to the
warping mill.
Having now fully described the nature and particulars of our said Invention;
and the manner of carrying the same into practical effect, we desire it to be
distinctly understood that we do not confine ourselves to the precise details
herein set forth, as such may be varied or modified without departing from the
principle thereof; but we claim as our Invention, and which to the best of
our knowledge and belief has not been hitherto used within this realm,
Firstly, the sword or bar of any shape attached to a slide rod to be moved
in and out of the shed when required.
Secondly, the double projection pulley having a central flange or á pulley
with one flange for the purpose of preventing the threads from closing:
And, thirdly, the general arrangement of the machine or apparatus as
herein described, and illustrated in the accompanying Sheet of Drawings.
In witness whereof, we, the said Samuel Clegg and John Kay, have
hereunto set our hands and seals, this Second day of September,
One thousand eight hundred and fifty-six.
Signed; sealed, and delivered by the within-
named Samuel Clegg and John Kay,
in the presence of

Patent Agent,
Manchester.
