Year: 1862

page_text: LETTERS PATENT to Frederick Luke Stott, of Rochdale, in the County of
Lancaster, Machine Maker, for the Invention of "IMPROVEMENTS
"
Sealed the 24th April 1863, and dated the 29th October 1862.
PROVISIONAL SPECIFICATION left by the said Frederick Luke Stott
at the Office of the Commissioners of Patents, with his Petition, on the
29th October 1862.
I, FREDERICK LUKE STOTT, of Rochdale, in the County of Lancaster,
Machine Maker, do hereby declare the nature of the said Invention for
"IMPROVEMENTS APPLICABLE TO MECHANISM OR APPARATUS FOR WARPING YARNS OR
THREADS," to be as follows:-
"
My improvements relate to warping machinery known as "warping mills,"
and consists, firstly, in combining the common "eye heck" and "beer heck
with a fixed plate or surface having inclines upon it, which act upon the
threads and cause them to pass "tapewise" upon the mill. This plate or surface
having inclines being fixed in front of the "pot rollers," and between them
and the "beer heck."
My improvements relate, secondly, to a modification of the common "eye"
heck," having eyes for each thread. In the common heck the eyes are placed.
in a straight line, and the threads from the bobbins in the creel (especially at
the outsides of the creel) have to come to the heck and pass through the eyes
at a considerable horizontal angle, which causes a large amount of friction
upon. the eyes, which consequently become cut by the constant wear of the
threads, and much breakage of threads arises from this cause. This part of

page_text: my Invention consists in curving the bars in which the eyes of the heck are
secured, and in turning each eye to such position that the axis of the hole
forming each eye will be in the horizontal line or direction of its thread,
extending between the bobbin and the eye or thereabouts; and this part of
my Invention also consists in curving the "beer-heck." to correspond with the
curved "eye heck," and in combining together the curved "eye heck,"
beer heck," and plate or surface having inclines referred to in the first part
of this Provisional Specification.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Frederick Luke Stott in the Great Seal Patent Office on
the 28th April 1863.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, FREDERICK
LUKE STOTT, of Rochdale, in the County of Lancaster, Machine Maker, send
greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Twenty-ninth day of October, in the year of our Lord
One thousand eight hundred and sixty-two, in the twenty-sixth year of
Her reign, did, for Herself, Her heirs and successors, give and grant unto me,
the said Frederick Luke Stott, Her special license that I, the said Frederick
Luke Stott, my executors, administrators, and assigns, or such others as
I, the said Frederick Luke Stott, 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 APPLICABLE TO MECHANISM AN APPARATUS FOR WARPING YARNS
OR THREADS," upon the condition (amongst others) that I, the said Frederick
Luke Stott, by an instrument in writing under my hand and seal, should par-
ticularly 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 Frederick Luke Stott, 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 Drawings (that is to say).:-

page_text: My improvements relate to warping machinery known as "warping mills,"
and to that part termed the "heck," and refers, in the first place, to a modifi-
cation of the common "eye' heck "having an eye for each-thread. Hitherto
the eyes of the common heck have been placed all in a straight line, and with
hecks so arranged the threads from the bobbins in the creels (especially at the
outside of the creel) have to come to the heck and pass through the eyes at a
considerable horizontal angle, and this produces a large amount of friction
upon the eyes,
which consequently become cut by the constant wear of the
threads, and much breakage of threads arises from this cause.
Now the object of my Invention is wholly or partly to remove this defect,
and my Invention consists in curving the bars in which the eyes of the heck
are secured, and in turning each eye to such a position that the axis of the
hole forming the eye will be in a radial line drawn from the centre of the
radius to which the heck is curved, so that the line of the axis of each eye
will agree as near as practicable with the direction of a horizontal line drawn
from the bobbin in the creel or from a point vertically above or below the
bobbin to the eye in the heck. The amount or degree of curvature to be
given to the heck will depend upon its size, the width of the creel, the distance
of the heck from the mill, and the distance of the creel from the heck.
My Invention also consists in curving beer hecks, which are placed
between the eye hecks and the "pot rollers," to correspond with the curvature
of the eye heck.
Fig. 1 of the Drawings shews a plan view of the curved heck made
according to my Invention, and Fig. 2, a side elevation looking at the concave
side; Fig. 3 and Fig. 4 are views corresponding to Fig. 1 and 2, but of a
curved "beer heck," which is placed between the "pot rollers" and "eye
heck."
These hecks are constructed in the same manner as the common straight
hecks, except that the bars a, which form the guide to the eyes or forks, the
bars b, in which the eyes or forks are secured, the bottom carrier c, and the
lifting rods d are all curved, as shewn. The convex side of the hecks is, of
course, placed towards the creel.
For the purpose of simplifying the construction of the hecks, the bars b
may be made without teeth, and in this case the lower parts of the eyes or
forks are screwed into the bars b, and are bent or cranked, as shewn in
Fig. 5, an end sectional view, and Fig. 6, a plan view, so as to come all in
the same line in the centre. This mode of cranking the eyes or forks is
also applicable for common straight hecks.
I have now particularly described the nature of my Invention, and the mode

page_text: of carrying the same into effect, and wish it to be understood that I claim as
my Invention the system or mode of constructing "eye" or "beer" hecks curved
in the manner and for the purpose herein-before described.
In witness whereof, I, the said Frederick Luke Stott, have hereunto
set my hand and seal, this Twenty-seventh day of April, in the year of 5
our Lord One thousand eight hundred and sixty-three.
F. L. STOTT. (L.S.)
