I ARTHUR CHARLES HENDERSON of 46 Southampton Buildings, Holborn in the county
of Middlesex, and 31 Lincoln Place, Leinster Street, Dublin, Patent Agent do hereby
declare the nature of the said invention for "IMPROVEMENTS IN MACHINERY FOR THE
MANUFACTURE OF WIRE HEALDS OR HEDDLES a communication to me from abroad by
Jean Bénazet, Mechanician, of the city of Reims in the Department of Marne in the
Republic of France to be as follows:-

In the accompanying drawings a machine of the description embodying the inven-
tion is shown, Fig. being a front vertical projection thereof. Fig. 2 being
horizontal projection of the same. Fig. 3 being a side projection seen in section.
Fig. 4 representing a heddle as completed by the inachine, which consists of a frame A,
supporting the several parts.
B, is a shaft transmitting motion to two pinions a. a turning the twisting
mechanism or twisters a². a³.
On this shaft B, a wheel b is keyed, this wheel by aid of an intermediate pinion c,
this
communicates to the nut d, a rotary motion inverse to that of the pinions a. a',
movement is necessary for forming the central eye of the heald.
The pinion c, and nut d through which the wire is passed, are supported by their
axes on two side plates e, on each of which a needle holder Fig. 3 is mounted each of
which slide in an iron box, themselves fixed to the plates e...
These two needle holders serve to regulate the length of the first and very close
twisting of the wire.
They are raised and lowered by aid of levers f, on which a bolt is mounted for
bending the wire on a needle g fixed in the centre of the nut d.
In raising the needles, three stop pins or needles are simultaneously raised,
two of these i. Fig. 2 form the close twist of the heald, and the third it, stops
the end of the wire, the other end of which is fixed to the movable piece j,
connected to the twister a³, having a rotary motion communicated to them by the
pinions a. a' in a direction opposed to that of the nut d.

page_text: The end loops and central eye of the heald are formed as follows. In inserting the
wire in the machine, it is first passed through, and bent behind the small groove 1,
of the twister a³, it then passes over the needle i and under the needle ¹, it is then
put through the nut d, behind the needle g, Figs. 1 and 3, it then passes over the
needle to the second piece j¹ of the twister a, Fig. 2. round a movable axis 2,
repasses behind, on the other side of the piece j¹, under a spring bolt 3, to prevent
the wire jumping in its rotary motion, again passes through the nut d on the
opposite side to its first passage through this nut, passes to the piece of the
twister a³, under the spring bolt 31, behind the axis 21, and stops under the
needle it.
By this means the end loops and central eye are formed.
After the first close twisting (produced by turning the fly V) the needles being in
a raised position, the lever is lowered, this lowers the needles i, i, and k.
The first end of the wire is then broken or cut which is fixed on the needle ", and
the other end fixed in the groove 1 is also cut.
The second or loose twisting is then effected by giving a turn to the fly wheel V.
The heald is now finished and to remove it from the machine the spring bolt 3. 31, are
depressed, this liberates the wire.
The lever D is then pressed to the left (this lever rests on the two axes where
the twisters are fixed) and the wire which is still held by the axes 2. 2¹, escapes,
and the heald jumps out of itself.
To keep the axes of the twisters in their normal position two levers l. press on movable
collars m, fixed on the axes of the twisters, these levers are secured by springs n. n',
and locking screws o. o¹ which regulate pressure as the wire shortens in twisting.

Improvements in Machinery for the Manufacture of Wire Healds
or Heddles.
I ARTHUR CHARLES HENDERSON of 46, Southampton Buildings, Holborn, in the
county of Middlesex, and 31, Lincoln Place, Leinster Street, Dublin, Patent Agent
do hereby declare the nature of the said invention for IMPROVEMENTS IN MACHINERY
FOR THE MANUFACTURE OF WIRE HEALDS OR HEDDLES, and in what manner the same is
to be performed, to be particularly described and ascertained in and by the following
statement, a communication to me from abroad by Jean Bénazet, Mechanician of the
city of Reims in the Department of Marne, in the Republic of France, to be as
follows:-
In the accompanying drawings Sheet 1 of which was filed with the Provisional
Specification a machine of the description embodying my invention is shown.
Fig. 1, being a front vertical projection thereof, the levers being omitted to show
the mechanism more clearly.
:
Fig. 2, being a horizontal projection of the same.
Fig. 3, being a side projection seen in section.
Fig. 4, representing a heddle as completed by the machine.
Figs. 5 to 29 Sheet 2 are details of the mechanism shown on a larger scale and
mentioned hereafter.
A, is the frame of the machine supporting the several parts.
B, is a shaft transmitting motion to two pinions a, a', turning the twisting
mechanism or twisters a², a³, where the wire is held.
On this shaft B, and in its centre a wheel b, is keyed, this wheel by aid of an
intermediate pinion c, communicates to the nut and pinion d, a rotary motion inverse
to that of the pinions a, a, this movement is necessary for forming the central eye of
the heald.
The pinions c, and nut and pinion d, through which latter the wire is passed are supported
by their axes on two side plates e, on each of which a needle holder k. k¹ Figs. 2 & 3.
is mounted each of which slides in an iron box themselves fixed to the plates e.
These two needle holders serve to regulate the length of the first and very close ⚫
twisting & Fig. 4 of the wire of the heddle at the central eye.
The needle holders k, k', and needles i, 2, 2, are raised and lowered by aid of
two levers or arms f, fixed on the lever C, by means of a handle. They are raised
in the first instance for the insertion of the wire in the machine and are intended to
limit the length of the very close twisting of the wire at the central eye and the end
loops of the heddle vide letters .c, Fig. 4.
These loops are formed as follows:-
All the needles are first raised by aid of a handle fixed to the lever C, as previously
described and the wire is then inserted in the machine by first passing one end

page_text: through and bending it behind a groove 1, on the piece j, of the twister a³ (see Fig. 2)
it then passes behind the needles i, i, and needle holders k, k¹, through the nut d,
behind the needle g, Figs. 1 and 3, it then passes behind the needle ², to the
second piece of the twister a, Fig. 2, round a movable axis 2, repasses on the
other side of the piece j', under a spring bolt 3, to prevent the wire jumping in its rotary
motion, again passes through the nut d, in the opposite side to its first passage through
this nut, passes to the piece j of the twister a³, under the spring bolt 31, behind the
axis 2¹, and stops at the needle i¹, where it is twisted once round this needle to fasten
off the wire. The fly wheel V, is then turned and the very close twisting a Fig. 4
at the eye and end loops of the heddle are formed.
The lever C, is then again acted on for withdrawing all the above named needles.
A single and gentle turn is then given to the fly wheel V, and the loose twisting x¹ of
the whole length of the heddle is then effected.
The heald is now finished and to remove it from the machine the spring bolts 3, 31,
are depressed this liberates the wire.
The first end of the wire which is fixed round the needle, is then broken or cut as
well as the other end held in the groove 1, in the piece j', of the twister a³. The
lever D, is then forced to the left (this lever communicates with the two axes on
which the twisters are mounted) and the wire which is still held by the axes 2, 21
escapes and the heald jumps out of itself.
To keep the axes of the twisters in their normal position two levers 1, Fig. 1 press
on movable collars m, fixed on the axes of the twisters, these levers are secured by
springs n,
n', and locking screws o, o', which regulate pressure as the wire shortens
in twisting.
Figure 5, Sheet 2 is an enlarged view of Fig. 3, seen from the opposite side,
showing more clearly the disposition of the side plates e, and one of the levers f, for
lifting the needle holders k, k¹.
Fig. 6, is a plan view showing the nut and pinion d, with the space between the
teeth for the passage of the wire, between which space is the needle g, on which the
central eye of the leddle is formed.
Figs. 7 and 8 are a front and side projection of the nut pinion d, showing the
aperture between the teeth for the passage of the wire.
Figs. 9, 9, are a vertical and horizontal projection of the needle y, which is fixed in
a socket of the nut d, by aid of a screw.
Figs. 10 and 11, represent a plate seen in front and side view having a slit in the
centre for the passage of the wire. This is mounted on the journals of the nut
pinion d, borne by the side plates e.
Figs. 12, 13, and 14, are respectively an end view, side view, and plan of one of
the twisters; springs placed beneath, and at the sides of these, serve to regulate
the position of two pieces of wood or blocks for preventing contorsion of the loops
of the heddle.
Figs. 15, 17, are two side views, Fig. 16, being a front view and Fig. 18, a
plan of the right hand movable piece j, (that on the left, does not require the
slot 1) fixed to and forming part of the twister for making the loop.
Figs. 19, 20, 21, are a front view, side view and plan, of a peg h, placed at the
side of the piece, regulated by a screw, (not shown in the drawings) to insure the
loop of the beddle leaving the machine perfectly straight.
Figs. 22, 23, are a front, and side view, of one of the springs 3, 31, fixed to the
pieces jj, to keep the wire in proper position.
Figs. 24, 25, 26, are severally a front, side view, and plan, of one of the movable
axes 2, 21, fixed to the twisters. These axes can be raised or lowered in their supports,
as desired, and their fixed by means of screws .
Figs. 27, 28, 29, are respectively a front, side view, and plan, of one of the supports
of the needle stops i, ; between the forks or branches a spring is placed. These
can be moved forwards or backwards by turning the screws E, which causes them
to slide on the guides P to regulate them in accordance with the dimensions of the
heddle.
