Improved Means for Throwing the Shuttle in Looms for Weaving
Fabrics which Require Upper and Lower Sheds.
We, L. HONORÉ & CIE., Manufacturers, of Rue Esperance, Roubaix, Nord,
France, do hereby declare the nature of this invention to be as follows:-
The object of this new loom is to manufacture mechanically carpets or other
textures for weaving which the shuttle has to pass a certain number of times
in the upper shed, then a certain number of times in the lower shed without
this succession of movements being determined.
In this new loom the shuttle boxes, one at each side are independent of the
batten and can receive a vertical and another horizontal movement, not only
the shuttle boxes being thus displaced, but also the driving arms and also the
tappets which throw the shuttle.
Fig. 1 of the annexed drawings shews by way of example the tying of the
wefts in one kind of the textures that can be woven on this loom.
Fig. 2 is a sectional elevation which shews in two different positions the paris
of the loom to which our invention applies. Fig. 3 is a front elevation of some
of these parts. Figs. 4 and 5 are respectively an elevation and a plan shewing
an arrangement for working the rod of the stop or organ which automatically
stops the loom in case the shuttle should not by accident re-enter its box.
Figs. 6 and 7 shew a modification of this arrangement.
The above mentioned movements of the shuttle boxes b their driving arms S
and pickers T are obtained as follows.
They are determined by a cam H keyed on a shaft A which is driven by
gearing at a speed depending on the kind of texture which is to be woven.
For instance, for the fabric shewn this shaft makes one revolution for every
G strokes of the batten, the cam being of such form as to produce the texture
indicated in Fig. 1. The cam H works the lever I which by means of the
link t, made in two pieces adjustable in length, works the arm K free with
its pinion on the shaft D. This pinion gears 2 to 1 with one keyed on the shaft E.
Thus for each quarter turn of 1) there is half a turn of E and the
excentric M presents alternately its great and its small radius to the roller of
the lever L pivoited at C. The shaft E extends across the loom to produce the
raising and lowering of the shuttle box b at the side opposite the excentric M.
The lever L supports the crutch N to which is fixed the pivot of the holder
of the shuttle driver. On the side where is the mechanism for inserting the
077

page_text: rod V (Fig. 1) the box bin its upper position would prevent this mechanism
from acting. To provide against this inconvenience, we make the box move
back when the batten advances and advance to its normal position for the throw
of the shuttle when the batten recedes. For this purpose, the arms U of the
batten, as well as the arms Q fixed outside on the shaft D and serving to guide
the ends of the boxes b, are provided with two ribs R in front and two behind.
When the batten advances the crutch N follows its movement until the head
of the rod m which is jointed to N at 12 meets the projection L'. When the
batten recedes the spring R¹ moves the crutch back to its former position.
To allow the shuttle to be propelled into the upper shed in order to keep the
back of the shuttle close to the reed, in other words to prevent it from over-
turning, we should guide it by means of a special reed, in order to make the
motion of the shuttle certain. This reed which consists of several arms with
sharp points at intervals of 5 centimetres, can move around an axis X and is
urged by a spring Y towards the cap of the batten B¹.
Adjusting screws Z with round heads fixed in the levers which carry the reed P,
abut against the head of the batten B₁ and hold the reed in position. The
arm serves for putting the reed l' in the position 1" when threads have to be
introduced. The reed P may be worked by an eccentric and levers so as to move
it independently of the batten.
To move the stop rod T¹ so that it may work at will whether the box be in
the upper or lower position, we have adopted the following modifications, which
we claim as new.
The harlequin or tongue a' which can turn round a spindle t works a small
lever, a small arm o of which abuts against the lug p of the stop rod.
This is shewn in Figs. 4 and 5.
The lever and arm are fixed on a spindle 3 which is mounted on the arm Q,
and the lever 3 has such length that when the tongue moves up and down with
the box it always slides along the lever. Whether the box be up or down,
when the shuttle enters it, it acts always in the same way on the tongue a¹ which
in its turn acts on the lug p through the lever and arm o.
In the modification shewn in Figs. 6 and 7 the two latter pieces are dispensed
with. On the spindle are two cars o and o³, of which the one or the other,
according to the position of the box b, is in contact with the lug p.
In order not to prevent the action of the change mechanism of the box when
the batten is in its forward position, the front arm 6 of the stop rod (Figs. 2
and 6) bears on a roller g' mounted on the lower arm of a bent lever the upper
arm of which is toothed. A piece engages in the teeth of the lever raising
the roller so that it raises the front arm of the stop rod and causes
the lug to move backwards so that it no longer in any way prevents movement
of the box, on the batten moving back the rod T being no longer subject to
the action of the roller g¹ is drawn by its spring to its normal position, and the
lug comes into contact with the ear o

Improved Means for Throwing the Shuttle in Looms for Weaving
Fabrics which Require Upper and Lower Sheds.
We, L. HONORÉ & CIE., Manufacturers, of Rue Esperance, Roubaix, Nord
France, do hereby declare the nature of this invention and in what manner the

page_text: same is to be performed, to be particularly described and ascertained in and by
the following statement:-
The object of this new loom is to manufacture mechanically carpets or other
textures for weaving which the shuttle has to pass a certain number of times
in the upper shed, then a certain number of times in the lower shed.
In this new loom the shuttle boxes, one at each side are independent of the
batten and can receive a vertical and another horizontal movement, not only
the shuttle boxes being thus displaced, but also the picking sticks and also the
pickers which throw the shuttle.
Fig. 1 of the drawings accompanying the Provisional Specification shews by
way of example the tying of the wefts in one kind of the textures that can be
woven on this loom.
Fig. 2 is a sectional elevation which shews in two different positions the parts
of the loom to which our invention applies. Fig. 3 is a front elevation of some
of these parts. Figs. 4 and 5 are respectively an elevation and a plan shewing
an arrangement for working the stop red or organ which automatically stops the
loom in case the shuttle should not by accident re-enter its box. Figs. and 7
shew a modification of this arrangement.
The above mentioned movements of the shuttle boxes the picking sticks S
and pickers T are obtained as follows.
They are determined by a cam H keyed on a shaft A which is driven by
gearing at a speed depending on the kind of texture which is to be woven.
For instance, for the fabric shewn this shaft makes one revolution for every
6 strokes of the batten, the cam being of such form as to produce the texture
indicated in Fig. 1. The cam H works the lever I which by means of the link t,
made in two pieces adjustable in length, works to and fro the arm K free with
its pinion on the shaft D). This pinion gears 2 to 1 with one keyed on the shaft E.
Thus for each quarter turn of the pinion on 1) there is half a turn of E and the
excentric M presents alternately its great and its small radius to the roller of
the lever L pivotted at C. The shaft E extends across the loom to produce the
raising and lowering of the shuttle box b at the side opposite the excentric M..
The lever L supports the crutch N to which is fixed the pivot t of the holder
of the picking stick. On the side where is the mechanism for inserting the
rod V (Fig. 1) the box in its upper position would prevent this mechanism
from 'acting. To provide against this inconvenience, we make the box move
back when the batten advances and advance to its normal position for the throw
of the shuttle when the batten recedes. For this purpose, the arms U of the
batten, as well as the arms Q fixed outside on the shaft D and serving to guide
the ends of the boxes b, are provided with two ribs R in front and two behind.
When the batten advances the crutch N follows its movement until the head
of the rod m which is jointed to N at meets the projection L'. When the
batten recedes the spring R¹ moves the crutch back to its former position.
To allow the shuttle to be propelled into the upper shed in order to keep the
back of the shuttle close to the reed, in other words to prevent it from over-
turning, we should guide it by means of a special reed, in order to make the
motion of the shuttle certain. This reed which consists of several arms with
sharp points at intervals of 5 centimetres, can move around an axis X and is
urged by a spring Y towards the cap of the batten B¹.
Adjusting screws Z with round heads fixed in the levers which carry the reed P,
abut against the head of the batten 13 and hold the reed in position. The
arm F serves for putting the reed P in the position 1" when required.
To move the stop rod T¹ so that it may work at will whether the box be in
the upper or lower position, we have adopted the following modifications, which
we claim as new:-
The harlequin or tongue a¹ which can turn round a spindle works a small
lever 13, a small arm o of which abuts against the lug p of the rod of the stop.
This is shewn in Figs. 4 and 5.

page_text: The lever 13 and arm o are fixed on a spindle 3 which is mounted on the arm Q,
and the lever 13 has such length that when the tongue moves up and down with
the box bit always slides along the lever. Whether the box be up or down,
when the shuttle enters it, it acts always in the same way on the tongue a¹ which
in its turn acts on the lug p through the lever 13 and arm o.
In the modification shewn in Figs. 6 and 7 the two latter pieces are dispensed
with. On the spindle are two ears o² and o³, of which the one or the other,
according to the position of the box b, is in contact with the lug p.
In order not to prevent the action of the change mechanism of the box when
the batten is in its forward position, the front arm 6 of the stop rod (Figs. 2
and 6) bears on a roller gl mounted on the lower arm of a bent lever the upper
arm of which is toothed. A piece 15 engages in the teeth of the lever + raising
the roller so that it raises the front arm of the stop rod and causes
the lug p to move backwards so that it no longer in any way prevents movement
of the box; on the batten moving back the rod T being no longer subject to
the action of the roller g' is drawn by its spring to its normal position, and the
lug p comes into contact with the lever 13.
Having now particularly described and ascertained the nature of our said
invention, and in what manner the same is to be performed, we declare that what
we claim in respect of shuttle mechanisms in looms for weaving fabrics which
require upper and lower shed, is:
1. The arrangement whereby the two shuttle boxes are rendered independent
of the batten and receive by suitable mechanism a vertical movement along with
the shuttles, the picking sticks and pickers so that the shuttles can be thrown
sometimes into the upper shed and sometimes into the lower shed, substantially as
described.
2. The arrangement whereby the two shuttle boxes are rendered independent
of the batten, and receive by suitable mechanism a vertical and a horizontal
movement relatively to the batten, along with the shuttles, the picking sticks
and pickers, so that the shuttles can be thrown sometimes into the upper shed and
sometimes into the lower shed, substantially as described.
3. The mechanism by which the vertical and the horizontal movements are
given to the shuttle boxes, shuttles, picking sticks and pickers, constructed and
arranged substantially as described.
4. The supplementary reed P for guiding the shuttle in the upper shed, sub-
stantially as described with reference to Fig. 2.
5. The stop mechanism arranged and operating substantially as described with
reference to Figs. 4 and 5.
6. The modified stop mechanism arranged and operating substantially as
described with reference to Figs. 6 and 7.
7. The combination of the parts g1 14 15 substantially as and for the purpose
set 'forth.
