Year: 1874

page_text: LETTERS PATENT to David Eastwood, of Mill House, Midgley, in the
Parish of Halifax, in the County of York, Worsted Spinner, for the
Invention of "IMPROVEMENTS IN LOOMS FOR WEAVING."
Invention of "IMPROVEMENTS IN LOOMS FOR WEAVING."
Sealed the 10th July 1874, and dated the 14th January 1874.
PROVISIONAL SPECIFICATION left by the said David Eastwood.
at the Office of the Commissioners of Patents, with his Petition,
on the 14th January 1874.
I, DAVID EASTWOOD, of Mill House, Midgley, in the Parish of Halifax,
in the County of York, Worsted Spinner, do hereby declare the nature
of the said Invention for "IMPROVEMENTS IN LOOMS FOR WEAVING," to be
as follows:-
This Invention relates to the construction and use of improved healds
for looms for weaving..
Healds constructed according to this Invention are made of strips of
metal (by preference steel being used). Through one end of each strip"
is a stave hole or holes, through which the heald staves are passed.

page_text: "
The "
eye or hole through which the warp is passed is formed at
any convenient distance from the end of the strip, by preference about
midway its length, and inasmuch as the strips must be so placed on the
staves as to present their edges in the direction of the warp beam the
strips are at each side of the eye slightly bent or twisted so as to afford
a clear and direct passage way for warp threads through the eyes of the
string constituting the heald.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said David Eastwood in the Great Scal Patent
Office on the 14th July 1874.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, DAVID
EASTWOOD, of Mill House, Midgley, in the Parish of Halifax, in the
County of York, Worsted Spinner, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Fourteenth day of January, in
the year of our Lord One thousand eight hundred and seventy-four,
in the thirty-seventh year of Her reign, did, for Herself, Her heirs and
successors, give and grant unto me, the said David Eastwood, Her
special licence that I, the said David Eastwood, my executors, admini-
strators, and assigns, or such others as I, the said David Eastwood,
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 IN LOOMS FOR WEAVING," upon the condition (amongst
others) that I, the said David Eastwood, my executors or admini-
strators, 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

page_text: Office within six calendar months next and immediately after the date
of the said Letters Patent.
NOW KNOW YE, that I, the said David Eastwood, 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 (that is to say):—
This Invention relates to the construction and use of improved healds
for looms for weaving.
Healds constructed according to this Invention are made of strips of
metal (steel by preference being used). Through one end of each strip
is a stave hole or holes, through which the heald staves are passed.
The "eye" or hole through which the warp is passed is formed at any
convenient distance from the end of the strip, by preference about
midway its length, and inasmuch as the strips must be so placed on the
staves as to present their edges in the direction of the warp beam the
strips are at each side of the eye slightly bent or twisted so as to afford
a clear and direct passage way for the warp threads through the eyes of
the strips constituting the heald.
The weight of the metal healds above described facilitates the working
of the treaddles employed for operating the healds, and cnables the
weights to be dispensed with.
Such being the nature and object of this my Invention in order that
the same may be fully understood I have hereunto annexed a Sheet of
Drawings, and have marked the same with figures and letters of
reference.
The heald stave A is passed through the hole B, as shewn at Figs. 1
and 2 (the improved heald being illustrated by Fig. 3 enlarged).
It will be seen that only one heald stave is requisite for each set of
healds, the top stave being dispensed with.
For making these my improved healds I employ an ordinary press or
punch for making the perforations; the holes are then smoothed by any
tool suitable, and the healds are then bent near the hole or "eye" by
means of the dies shewn at Fig. 4.
When the weight of the healds is not sufficient to work the treaddles
box tannets may be used

page_text: Having thus fully described the nature and object of this my
Invention, together with the manner in which the same is to be per-
formed or carried into practical effect, I would have it understood that
I do not claim the use of metal healds apart from the construction of
healds, as above described, but what I do claim is, the construction
and use of healds, as shewn in the Drawings and herein fully
described.
In witness whereof, I, the said David Eastwood, have hereunto
set my hand and scal, this Eleventh day of July, in the
year of our Lord One thousand eight hundred and seventy-
four.
DAVID EASTWOOD. (L.S.)
