1, THOMAS ALLEN LEIGH of 19 James Street, Liverpool in the County of
Lancaster, Merchant, do hereby declare the nature of this invention to be as
follows:-
'
This invention relates to the device in looms which serves to check and hold the
shuttle on entering the box at either end of the lay.
It is well known that the binder, which is a piece of cast iron of a form known
to everyone familiar with looms, is secured at one end to the outside of the back
of the shuttle-box by the projecting piece (the latter being bolted to said back of
the shuttle-box), while at the other end the binder is forced by a spring to project
into the shuttle-box, in such manner that the slightly convex face of said binder
shall press against the shuttle on its entering the box, and hold it firmly until
forcibly expelled by the next pick. Of course it will be understood that the
shuttle on entering the box forces the swell backwards, but the binder continues
to press with considerable force against the side of shuttle, thus offering great
resistance to the release of the shuttle, when the moment comes for it to be driven
to the other end of the lay. Now it is clear that a force sufficient to overcome
this resistance must be employed; in other words, that the pick stroke must be
delivered with great force against the end of the shuttle. The heaviness of the
work thus laid on the pickers, causes considerable wear and tear of these parts
and their accessories (picking staffs, straps, etcetera) necessitating frequent renewals
of pickers a heavy item of expenditure in all weaving establishments.
Now the object of this invention is to provide a binder, which, while
satisfactorily performing the work of holding the shuttle in the box, and pre-
venting direct concussion with the picker, shall offer little or no resistance to the
release of the shuttle, when started on its travel to the opposite box. It is clear
that, with the attainment of this object, the power necessary to drive the shuttle
from one box to another will be greatly diminished, and that the pickers and their
accessories will, in consequence, be subjected to less wear and tear, and call for less
frequent renewals, than with the present form of binder.
In carrying out this invention, a binder is provided consisting of a simple cast
iron lever with a pin passing through a hump or projection in the back, near the
centre of said lever, such pin being designed to work in two small bearings in the
back of the shuttle-box.
By means of this pin passing through the projection near the centre of the
binder the said binder is secured to the back of the shuttle-box. But as this pin
works in bearings, as already said, it follows that the binder also has a certain
amount of horizontal play, the pin acting as the fulcrum of said play or move-
ment, the binder being rigidly attached to the pin and therefore moving with it on
its bearings. Or, if preferred, the pin may be rigidly attached to the back of the
shuttle-box and the binder may be arranged to move on the pin, the only object
being to secure the horizontal movement of binder on a fulcrum situated at about
its centre.
To simplify matters that portion of the binder situated to the right of the pin
will be called the inner member of said binder, and the portion of the binder
situated to the left of the pin the outer member of the binder.

page_text: The horizontal play of the binder, to which allusion has been made, is limited
at one end by a light spring (one end of which is bolted to back of the shuttle-box,
while the other rests on the back of the inner member of the binder) and at the
other end by a catch, which is also bolted to the back of the shuttle-box and
is so placed as to check the outward thrust of the outer member of the binder.
Before the shuttle enters the box, the interior face of the inner member of the
binder is flush, or exactly level, with the interior surface of the back of shuttle-
box, but the interior face of outer member of the binder, which is so shaped as
to tally with the tapering end of the shuttle, projects into the interior of the
shuttle-box.
'
Now, when the shuttle enters the box, its tapering side necessarily
encounters the projecting outer member of the binder, thus preventing direct
concussion with the picker. But the shuttle on striking the outer member of the
binder, of course forces that member backwards, and as the binder moves hori-
zontally on the pin bearings mentioned above, the inner member of the binder is
simultaneously forced inwards, in such a way as to press against the side of the
shuttle, and to hold the same securely in the box. But when the next pick is
given, the inner member of the binder offers little or no resistance to the release
of the shuttle, as that member, by reason of the horizontal play of the binder on
the pin bearings is forced backwards, the light spring offering no obstacle to such
backward movement, as it is very light and is only introduced to keep the binder
in place, and ensure a steady movement of shuttle on leaving and entering the box.
Consequently the power necessary to drive the shuttle from the box, is corre-
spondingly reduced.
It will be seen that by the use of a binder working freely within certain limits,
in a horizontal direction, on bearings attached to the back of shuttle box, or on a
pin attached to back of shuttle-box, the shuttle is held firmly after entering the
box, while at the same time, little or no resistance is offered to its release, when
the picker starts it on its travel to the opposite box.
Another advantage of this invention, over and above the saving of power and
the diminution of the wear of the pickers, may be noticed. The strong pressure
of the spring binder ordinarily used against the side of the shuttle has a tendency,
when the shuttle is expelled from the box, to cause it to deviate from the straight
direction, thus causing frequently to come into contact with the warp threads,
and break them. But the shuttle, with this new binder, meeting with no
resistance on leaving the box, is driven in a steady straight line from end to end
of the lay.

A communication by JOHN BANNISTER, of No. 9, la Calle de la Independencia,
Mexico, in the Republic of Mexico, Machinery Merchant.
I, THOMAS ALLEN LEIGH of 19 James Street, Liverpool in the County of
Lancaster Merchant, do hereby declare the nature of this invention and in what
manner the same is to be performed, to be particularly described and ascertained
in and by the following statement :-
This invention relates to the device in looms which serves to check and hold the
shuttle on entering the box at either end of the lay.

page_text: It is well known that the binder, which is a piece of cast iron of a form known,
to everyone familiar with looms, is secured at one end to the outside of the back
of the shuttle-box by a projecting piece (the latter being bolted to said back of
the shuttle-box), while at the other end, the binder is forced by a spring to project
into the shuttle-box, in such manner that the slightly convex face of said binder
shall press against the shuttle on its entering the box, and hold it firmly until
forcibly expelled by the next pick. Of course it will be understood that the
shuttle on entering the box forces the swell or binder backwards, but the binder
continues to press with considerable force against the side of shuttle, thus offering-
great resistance to the release of the shuttle, when the moment comes for it to be
driven to the other end of the lay. Now it is clear that a force sufficient to
overcome this resistance must be employed; in other words, that the pick stroke
must be delivered with great force against the end of the shuttle. The heaviness-
of the work thus laid on the pickers, causes considerable wear and tear of these
parts and their accessories (picking staffs, straps, etcetera) necessitating frequent-
renewals of pickers, a heavy item of expenditure in all weaving establishments.
Now the object of this invention is to provide a binder, which, while satisfactorily
performing the work of holding the shuttle in the box, and preventing direct
concussion with the picker, shall offer little or no resistance to the release of the-
shuttle, when started on its travel to the opposite box. It is clear that, with the
attainment of this object, the power necessary to drive the shuttle from one box to
another will be greatly diminished, and that the pickers and their accessories will,..
in consequence, be subjected to less wear and tear, and call for less frequent
renewals, than with the present form of binder.
My invention consists in arranging the binder in the form of a lever or bell
crank having limited travel so that the shuttle shall, by coming in contact with one
part of the lever, cause another part of it to press forcibly against the shuttle at
approximately right angles with the line of motion of said shuttle and thus act.
as an effectual brake or clamp so long as the pressure of the shuttle is forward,.
the clamping pressure practically ceasing the moment the forward pressure of the
shuttle ends.
This invention will be best understood by referring to the accompanying
drawing, in which,
Figure 1 is a plan of a shuttlebox with this improved binder applied, and
Figure 2 a detail of the binder.
In these
A is the shuttlebox, and B the binder or swell which is preferably of the
form shown in Figure 2. This binder is pivoted at or about its centre to the
back of the shuttlebox, a portion of the latter being cut away to receive it as shown.
in Figure 1, and a pin C passing through a lug Ď on the binder, and brackets E
secured to the back of the shuttlebox, serve as a fulcrum for the said binder to
turn on. F is the shuttle, G, the picker, H a catch to limit the horizontal
movement of the binder, and I a spring to keep the binder or swell in position
and to steady the movement of the shuttle on the latter leaving and entering:
the box.
The mode of action is as follows, and to simplify matters that portion of the
binder B situated to the right of the pin or fulcrum C will be called the inner
member of said binder, and the portion of the binder situated to the left of the pin.
or fulcrum, the outer member of the binder.
Before the shuttle F enters the box, the interior face of the inner member of
the binder is flush, or exactly level, with the interior surface a of the back of
shuttle-box A, but the interior face 6¹ of outer member of the binder, which is so
shaped as to tally with the tapering end of the shuttle, projects into the interior of
the shuttle-box, or can be provided with an antifriction wheel.
Now, when the shuttle enters the box, its tapering side necessarily encounters
the projecting outer member of the binder, thus preventing direct concussion with.
the picker G. But the shuttle on striking the outer member of the binder, of

page_text: course forces that member backwards, and as the binder moves horizontally on its
pivot C, the inner member of the binder is simultaneously forced inwards, in such
a way as to press against the side of the shuttle, and to hold the same securely in
the box. But when the next pick is given, the inner member of the binder offers
little or no resistance to the release of the shuttle, and is forced backwards, the
light spring I offering no obstacle to such backward movement, as it is very light
and is only introduced to keep the binder in place, and ensure a steady movement
of the shuttle on leaving and entering the box. Consequently the power necessary
to drive the shuttle from the box, is correspondingly reduced.
It will be seen that by the use of a binder working freely within certain limits,
in a horizontal direction, on bearings attached to the back of shuttle-box, the
shuttle is held firmly after entering the box, while at the same time, little or no
resistance is offered to its release, when the picker starts it on its travel to the
opposite box.
•
Another advantage of this invention, over and above the saving of power and
the diminution of the wear of the pickers, may be noticed. The strong pressure
of the spring binder ordinarily used against the side of the shuttle has a tendency,
when the shuttle is expelled from the box, to cause it to deviate from the straight
direction, thus causing it frequently to come into contact with the warp threads,
and break them. But the shuttle, with this new binder, meeting with
resistance on leaving the box, is driven in a steady straight line from end to end
of the lay.
no
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, as communicated to me
by my foreign correspondent, I declare that what I claim is :-
-
1. A shuttle swell or binder for power looms, pivotted at or about its centre to
the shuttlebox in such manner that the shuttle on entering the box encounters one
end of the said binder, thus preventing direct concussion with the picker and at the
same time turning the binder on its pivot and forcing the opposite end of the same
down on the shuttle substantially as and for the purposes described.
2. The combination, with a shuttle binder such as described in Claim 1, of a
catch limiting the movement of the said binder and of the spring keeping the
binder in position and steadying the movement of the shuttle on entering and
leaving the box.
.
3. The general arrangement and construction of the shuttle swell or binder on
the bell crank or lever principle, whereby while the shuttle is held securely in the
box on entering the same, very little resistance is offered to its passage out on its
travel to the opposite box and consequently any deviation from the straight line in
travelling to the end of the lay is prevented.
