page_text: LETTERS PATENT to Edward Tatham Swainson and George Haydock,
both of Preston, in the County of Lancaster, for the Invention
of "IMPROVEMENTS IN LEASING' WARPS IN DRESSING MACHINES CALLED
'SLASHERS,' WHICH IMPROVEMENTS ARE ALSO APPLICABLE TO OTHER WARP
DRESSING MACHINES."
Sealed the 1st July 1873, and dated the 13th May 1873.
PROVISIONAL SPECIFICATION left by the said Edward Tatham
Swainson and George Haydock at the Office of the Commissioners
of Patents, with their Petition, on the 13th May 1873.
We, EDWARD TATHAM SWAINSON and GEORGE HAYDOCK, both of
Preston, in the County of Lancaster, do hereby declare the nature of
the said Invention for "IMPROVEMENTS IN 'LEASING' WARPS IN DRESSING
MACHINES CALLED 'SLASHERS,' WHICH IMPROVEMENTS ARE ALSO APPLICABLE TO
OTHER WARP DRESSING MACHINES," to be as follows:-
-
Our Invention relates to a method of obtaining a perfect "lcase" of
the warps in machines called "slashers" so as to prevent the warp

page_text: threads from getting crossed. We take the "lease" in front of the
back beams and before the warp passes through the machine.
The yarn from each alternate beam passes through a comb made
with wire teeth, each having a notch in which the warp is placed,
whilst the yarns from the intermediate beams pass between the wires of
the comb; and it will be evident that by raising the combs every
alternate warp thread (that is, all the warp threads of each alternate
beam) which are in the notches of the comb teeth) will be raised. The
"lease band" is then pressed through from side to side underneath
these raised threads, and thus a perfect "lease" of each alternate
thread across the warp is obtained, and a very great saving in time
and trouble is thereby effected, and the crossing of the yarn entirely
prevented.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by tho said Edward Tatham Swainson and George Haydock
in the Great Seal Patent Office on the 13th November 1873.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, EDWARD
TATHAM SWAINSON and GEORGE HAYDOCK, both of Preston, in the
County of Lancaster, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Thirteenth day of May, in the 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 us, the said Edward Tatham Swainson and George
Haydock, Her special license that we, the said Edward Tatham Swain-
son and George Haydock, our executors, administrators, and assigns,
or such others as we, the said Edward Tatham Swainson and George
Haydock, 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 LEASING' WARPS IN DRESSING MACHINES
CALLED 'SLASHERS,' WHICH IMPROVEMENTS ARE ALSO APPLICABLE TO OTHER WARP

page_text: DRESSING MACHINES," upon the condition (amongst others) that we, the
said Edward Tatham Swainson and George Haydock, our executors,
or administrators, by an instrument in writing under our or one of
our, or their, or one of their hands and scals, 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 Edward Tatham Swainson, on
behalf of myself and the said George Haydock, 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 and accompanying Drawings (that is to say) :-
Our Invention relates to a method of obtaining a perfect "lease" of
the warps in machines called "slashers," so as to prevent the warp
threads from getting crossed. We take the "lease" in front of the
back beams and before the warp passes through the machine.
The yarn from each alternate beam passes through a comb made
with wire teeth, each having a notch in which the warp is placed,
whilst the yarns from the intermediate beams pass between the wires
of the comb; and it will be evident that by raising the combs every
alternate warp thread (that is, all the warp threads of each alternate
beam which arc in the notches of the comb teeth) will be raised. The
"lease" band is then passed through from side to side underneath
these raised threads, and thus a perfect "lease" of each alternate thread
across the warp is obtained, and a very great saving in time and trouble
is thereby effected, and the crossing of the yarns entirely prevented.
Such being the nature and object of the said Invention, I will now
proceed to describe more in detail the manner in which the same is to
be or may be performed or carried into practical effect, and in order
that the same may be clearly understood we have annexed hereunto
a Sheet of Drawings illustrative thereof, and have marked the same
with figures and letters of reference, corresponding with those in the
following explanation thereof:-
Fig. 1, in the annexed Drawings, represents a longitudinal section of

thereto; Fig. 2 is a side elevation of the same; and Fig. 3 is a detached
view (full size) of part of the comb, showing the form of the dents.
a, a, is the framing supporting four warp beams b, b, which are so
arranged that the yarn from all of them passes off at the top; c, c, is
a carriage capablo of sliding in slots d, d, and moved either backwards
or forwards by means of cords or chains e, e, attached thereto and
passing round pulleys f,f¹. The pulley ƒ may be turned when required
by means of a winch handle applied to the square end of its shaft or
axis, or it may be driven by gearing from any convenient moving part
of the machine. The carriage c, c, supports two combs, one of which g is
an expanding comb with plain teeth or dents, and is for the purpose of
opening out the threads. This comb is carried at each end by a short
lever h, h, which is provided with a bowl i, i, running on an inclined
rail k, k; and the other comb 1, which (if preferred) may also be
an expanding one, has its dents formed with notches on one side, as
shown at Fig. 3, and is capable of being raised or lowered when required
by means of a rack and pinion m, m.
The action of the apparatus is as follows:- The carriage being in
the position shown in dotted lines, and both combs raised above the
warps, the carriage is caused to move towards the machine in the s
direction of the arrow, cither by turning the drum ƒ by means of
a handle or by gearing, as before explained. As the carriage moves
along the bowl i running down the incline on the rail k, as shown at
Fig. 2, lowers the comb g, which opens and expands the warps. The
comb is now to be lowered by turning the handle n, n, and then raised a
again by turning the handle in the reverse direction, when every
alternate warp thread falling into the notches on the dents of the
comb will be raised, as shown at Fig. 1, and the warps of the first and
second beam being thus crossed a "lease" band (or rod, or both) is
passed through the space between them, and the apparatus is then a
moved on to the next pair of warp beams, where the lease is again
taken, and so on, if there are more than four beams. The "lease" is
also similarly taken between the warps of the first pair of beams and.
the second pair of beams, and so on if there are more than two pairs of
beams.
Having now described the nature and object of our said Invention,
togathon with them

page_text: or carried into practical effect, we wish it to be understood that wo
claim as our Invention the apparatus shown on the Drawings, and
herein-before described, for taking the "lease" in such machines in front
of the back beams at the feeding end, and before the warp passes
through the machine, and more especially we claim the construction of
the comb with notches in one side of its dents, as shown at Fig. 3.
In witness whereof, I, the said Edward Tatham Swainson, on behalf
of myself and the said George Haydock, have hereunto set my
hand and scal, this Eleventh day of November, in the year of our
Lord One thousand eight hundred and seventy-three.
