IMPROVEMENTS IN THE CONSTRUCTION OF HEALDS FOR Looms
Year: 1869

page_text: LETTERS PATENT to Gabriel Cherpit, of Manchester, in the County
of Lancaster, Engineer, for the Invention of "IMPROVEMENTS IN THE
CONSTRUCTION OF HEALDS FOR Looms."
Sealed the 29th April 1870, and dated the 16th November 1869.
PROVISIONAL SPECIFICATION left by the said Gabriel Cherpit at the
Office of the Commissioners of Patents, with his Petition, on the
16th November 1869.
I, GABRIEL CHERPIT, of Manchester, in the County of Lancaster,
Engineer, do hereby declare the nature of the said Invention for
"IMPROVEMENTS IN THE CONSTRUCTION OF HEALDS FOR LOOMS," to be as
follows:-
My Invention is applicable to wire healds, and it consists in an
improved mode of constructing such healds whereby the friction on the
warps is reduced, and the number of the healds in weaving fine fabrics.
can be diminished.
In performing my Invention I make the eye of the heald of a flat
link of wire, and I connect the eye to the top and bottom bars of tho

page_text: heald by wires looped into the link, and soldered or not; or I connect
the link to the wires reaching to the top and bottom bars by means of
small metal or other beads.
Another part of my Invention consists in making two eyes, one above
the other, in the heald, through each of which a warp thread may be
passed, whereby the number of healds in a set is reduced, thus pre-
venting crowding in fine fabrics. In this case the links may be looped
together or connected by beads.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Gabriel Cherpit in the Great Seal Patent Office on
the 16th May 1870.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, GABRIEL
CHERPIT, of Manchester, in the County of Lancaster, Engineer, send
greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Sixteenth day of November, in the year
of our Lord One thousand eight hundred and sixty-nine, in the thirty-
third year of Her reign, did, for Herself, Her heirs and successors, give
and grant unto me, the said Gabriel Cherpit, Her special license, that I,
the said Gabriel Cherpit, my executors, administrators, and assigns, or
such others as I, the said Gabriel Cherpit, 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 THE CONSTRUCTION OF HEALDS FOR
LOOMS," upon the condition (amongst others) that I, the said Gabriel
Cherpit, 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 Gabriel Cherpit, do hereby declare
the nature of my said Invention, and in what manner the same
a

page_text: is to be performed, to be particularly described and ascertained in and
by the following statement (that is to say) :-
My Invention is applicable to wire bealds, and it consists in an
improved mode of constructing such healds whereby the friction on the
warps is reduced.
In performing my Invention I make the eye of the heald by crossing
the wire, and I cover the crossings by small metal or other beads. The
wires are connected to the top and bottom bars of the heald.
Another part of my Invention consists in making two eyes, one above
the other, in the heald. In this case the eyes may be looped together
or connected by beads.
And in order that my Invention may be fully understood I will
proceed to describe the accompanying Sheet of Drawings, in which
Fig. 1 represents part of a heald constructed according to my improve-
ments.
a is a flat link of brass or other wire forming the eye through which
the warp thread is drawn; the eye is connected to the top bar of the
heald by the wire b, which is looped into the eye and to the bottom bar
of the heald by the wire c, which is a continuation of the wire forming
the eye, as shewn in Fig. 1*, in which the wire is shewn crossed through
the small metal or other bead d, shewn best in the edge view Fig. 2.
The ends of the wire c are twisted together below the bottom bar. The
heald consists of any convenient number of the eyes a with the loops
or wires and c by which they are connected to the top and bottom
bars of the frame.
Fig. 3 represents a modification of my improved healds. In this
case the eye a and the wires b and c are all made out of a single piece of
wire, which is bent into the form shewn in Fig. 3* to make the eye, and
at each crossing the wire passes through a bead ; the ends of the wire
are twisted together at the top or bottom.
Figs. 4 and 5 represent another modification of my improved healds.
In this instance each heald is made with two eyes a, a, placed one above
the other. The eyes are formed by crossing the wire, as above described,
and at each crossing is a bead d.
In Fig. 5 I have shewn each wire of the heald passing direct from
cach side of the top and bottom bars. In this case the healds arc.fixed
to wires above and below the top and bottom frames. The other healds,

page_text: shown in Figs. 1 and 3, may be made in the same manner; this mode of
construction reduces the number of shafts required in the loom, but the
healds, shewn in Figs. 3 and 4, may also be crossed or single in the
centre, as shewn in Fig. 2.
I wish to remark that the ends of the eyes may be soldered as
heretofore customary, if desirable..
Having thus stated the nature of my Invention, and described the
manner of performing the same, I declare that I claim,-
First. The use of beads made of metal or other materials for forming
the ends of the eyes of healds, and for securing the crossing of the wire
of which the heald is made.
Secondly. Connecting the healds direct from each side of the top and
bottom bars, as shewn in Fig. 5, and as described.
And, lastly. The heald with two eyes, one placed above the other, as
shewn and described in reference to Fig. 4.
In witness whereof, I, the said Gabriel Cherpit, have hereto set
my hand and seal, this Fourteenth day of May, One thousand
cight hundred and seventy.
GABRIEL CHEKPIT.
