TO ALL TO WHOM THESE PRESENTS SHALL COME, I, WILLIAM
RANDAL HARRIS, of the City of Manchester, in the County of Lancaster,
Machinist, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Twenty-ninth day of January, in the year of our Lord
One thousand eight hundred and sixty-six, in the twenty-ninth year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto me, the
said William Randal Harris, Her special license that I, the said William
Randal Harris, my executors, administrators, and assigns, or such others as
1, the said William Randal Harris, 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 " IMPROVE-
MENTS IN WEAVERS' HEALDS OR HEDDLES," upon the condition (amongst others)
that I, the said William Randal Harris, my executors 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 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 William Randal Harris, 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 thereof, reference being had to the figures on the accom-
panying Sheet of Drawings, and to the letters of reference marked thereon
(that is to say):-
This Invention consists in making weavers' healds or heddles of improved
forms for the purpose of allowing more space for the warp and enabling a
greater number of ends to be placed in a given space than in the ordinary
healds, and also for obtaining many other advantages.
Figs. 1, 2, and 3 are end views of my improved forms of one leaf of healds
or heddles, and in all the Figures a represents the heald shafts or sticks;
b, the foundation cords or tapes or their equivalents; c or c¹, the heald cords
or tapes or their equivalents; and d, the eyes for the passage of the warp.

page_text: In Fig. 1 there are four heald cords, each having an eye, but only three eyes
are seen, the fourth eye of the cord, c', being behind or in the same row of
eyes as the middle eye. In Fig. 2 there are four heald cords and four eyes,
the fourth eye being seen because one of the heald shafts is thicker than the
other; and in Fig. 8 there are two heald cords and two eyes, which numbers
of cords and eyes extend in rows across the width of the leaf of healds or
heddles; and as in all cases there is a leash in the heald cords or their equi-
valents the healds are very free and open.
I may here remark that these improved forms apply to all descriptions of
healds or heddles, whether the eyes are knitted or made of metal or other
material, whether the healds are made entirely of metal or a combination of
cords with metal, and also whether the healds are made by hand or machinery
or by a combination of the two, it being understood that the heald cords or
their equivalents are fastened to the foundation cords or their equivalents by
any of the ordinary methods, or by stringing them on rods or wires attached
to the heald shafts or sticks.
Having now described the nature and particulars of my said Invention,
and the manner in which the same is to be performed, I desire it to be under-
stood that I claim the improved forms of weavers' healds or heddles as shewn
in the accompanying Sheet of Drawings.
In witness whereof, I, the said William Randal Harris, have hereunto set
my hand and seal, this Twenty-sixth day of July, in the year of our
Lord One thousand eight hundred and sixty-six.
Sigued, sealed, and delivered by the
within-named William Randal Harris
in the presence of
E. J. HUGHES,
Patent Agent,
Manchester.
