IMPROVEMENTS IN HEALDS OR HEDDLES USED IN LOOMS FOR WEAVING
Year: 1878

page_text: LETTERS PATENT to Charles Guillaume Roger, of Paris, Boulevard de Stras-
bourg, No. 23, Manufacturer, for the Invention of "IMPROVEMENTS IN HEALDS
OR HEDDLES USED IN LOOMS FOR WEAVING."
Sealed the 12th November 1878, and dated the 17th May 1878.
PROVISIONAL SPECIFICATION left by the said Charles Guillaumo Roger
at the Office of the Commissioners of Patents on the 17th May 1878.
CHARLES GUILLAUME Roger, of Paris, Boulevard de Strasbourg, No. 23, Manu-
facturer. "IMPROVEMENTS IN HEALDS OR HEDDLES USED IN LOOMS FOR
WEAVING."
This Invention relates to improvements in healds or heddles used in looms for
weaving, and consists in slitting flat or like metal strips or rods in one or more
placos or parts of their length by a combined punching and cutting operation, and
in pressing the parts on each side of the slit or slits away from each other as to
form eyes or apertures, through which the warp or other threads can be passed and
held at the required distances from each other.
In some cases two slits are formed close together, and then the two outer portions
are pressed in the same direction, the part between the two slits being pressed in
the reverse or opposite direction, one eye for every two slits being formed for the
purpose before mentioned.
The press or punching apparatus I purpose using has a cutting blade above,
and a matrix below, the matrix being held up to its work by a spring fitted to a
fixed part of the press.
The matrix has a couple of slots in it, through which screw pins are passed to
guide it in its up movement under the pressure of the spring, and in its downward
movement by the pressing contact of the cutting blade or "force."
For making the two slits, I arrange a pressure cutter between two plates, the
cutter being below the level of the plates to push that part of the metal strip (in
which the eye has to be formed) into a recess in the matrix, the operation severing

page_text: the metal at that part, and the pressure bending the metal to form the eye at the
same time.
The ends of the metal strips or other body employed may be left flat, or they may
be turned to form hooks.

SPECIFICATION in pursuance of the conditions of the Letters Patent filed by
the said Charles Guillaume Roger in the Great Seal Patent Office on the
15th November 1878.
CHARLES GUILLAUME ROGER, of Paris, Boulevard de Strasbourg, No. 23, Manu-
facturer. "IMPROVEMENTS IN HEALDS OR HEDDLES USED IN LOOMS FOR
WEAVING."
My Invention relates to healds or heddles to be used in looms for weaving,
said healds or heddles being made from strips or rods of iron, copper, steel, or other
metal, in which an eye is formed by a depression or forcing of one portion away
from another portion, or otherwise dividing the metal by means of a die and
matrix.
The strip or rod of metal may be rounded at each end and formed with hooks.
The annexed Drawings clearly explain my Invention.
Figures 1 and 2 is a face and edge view or profile respectively, of a thin plate or
strip of metal a, destined to serve as a heald or heddlo, it is in this rod or strip
that the eye b is formed, as is seen in Figures 3 and 4. This cyc may be made by
means of a die and a matrix, such as I have shown in Figures 5 and 6, or by those
shown in Figures 7 and 8.
The upper stamp or die is fixed by its body in the moveable head of a press, and
is destined to doscend upon the matrix d.
The projections or jutting portions of the dic and matrix c and d are such that
when the strip of metal a is placed between them, one part of the strip a is made to
separate itself from the other part of the same strip to obtain by the division the
eye c, as represented in Figures 3 and 4.
The top of the strip a by the action of the die and matrix is slit, or a picce may
be removed from the strip as at i, in Figure 9, when the portions at each side
of the slit may be separated for the formation of the eye c, as Figures 10
and 11.
By changing the projections on the die and matrix c, d, as shown in the views,
Figures 12, 13, 14, and 15, the form of the eye in the strip may be modified by
stamping or severing the strip, Figure 16, in two places, and pressing the two
outer portions , l, in one direction, and the inner portion j in the other, whereby
the eye, as in Figures 17 and 18, is formed,

page_text: Having now described the nature of my said Invention, and in what manner
the same is to be performed, I declare that I claim,―
The improvements in healds or heddles to be used in looms for weaving,
as set forth and as shown in Figures 3, 4, 9, 10, 11, 17, and 18 of the annexed
Drawings.
Secondly. Separating or slitting strips or rods of metal and the formation of
eyes in said strips by forcing apart the portions where so slitted or separated
for the manufacture of healds or heddles used in looms for weaving purposes as
described.
In witness whereof, I, the said Charles Guillaume Roger, have hereunto set
my hand and seal, this Thirteenth day of November, One thousand eight
hundred and seventy-eight
CHARLES GUILLAUME ROGER. (L.S.)
