Improvements in or connected with Loose Reed and Picking
Motions of Looms.

Foreman, both of Black Dike Mills Queensbury in the County of York, do hereby
declare the nature of this invention to be as follows:-
This invention relates,

"
Firstly To improvements in loose reed motions of looms for weaving, the object
being to stop the loom, when a shuttle is caught in the race, before the "beat up
is made, thus preventing damage being done to the warps or shed.
Secondly-To improvements in pick and pick looms where levers are employed
for controlling the sliding of the picking tappets on their shaft wherein we employ
apparatus for preventing more than one of the said levers from being operated or
operating on the picking tappet at one and the same time, thus obviating breakage
or faults in the weaving.
According to this invention and referring firstly to the loose reed motion.
Below the
The ordinary reed and reed case are employed, the reed case being connected to
the stop rod as usual the connecting arms between the reed case and stop rod being
extended to the front of the loom so as to form handles by which the reed case can
be moved and opened or closed by the operation. On each of the said handles or
connections which are near each end of the loom we mount runners.
runners and fixed to each slay sword is a stud on which is loosely mounted a curved
lever one end of which rests against the back of the runner above mentioned, the
other end being cranked upwards and extending towards the front of the loom. A
second curved lever mounted on the same stud as the first lever rests against the
front of the before mentioned runners, and the other end of this lever is connected
by spiral spring to any fixed part of the loom.
Mounted loosely on a stud, fixed on each slay is a beak or finger which rests on
the cranked end of the first mentioned lever. At or near and extending the length
of the front of the loom is a bar free to move in slides, and on this bar, which is
connected with the ordinary stop handle, are the "frogs."
When a shuttle is caught in the race, and the reed turned in its cap, the stop rod
makes a part revolution, as ordinary, and the runners on the two handles press
against the first mentioned lever, and the cranked ends of same are lowered as are
also the beaks or fingers resting thereon, so that as the slay moves forward to the
"beat up" the fingers or beaks come in contact with the "frogs" (or a recess
formed in same) and the latter and the sliding bar are moved and the loom is
"knocked off," and as the sliding bar has only a limited amount of movement, when
this limit is reached the slay is prevented from moving forward and no "beat up'
is made. The second mentioned lever and spring hold the reed case in its normal

or fingers clear the "frogs" when the shuttle is "boxed."
"
The improvement in pick and pick looms consists in connecting the levers which
control the sliding tappets as follows:-Each of the said levers has a light rod
attached to it and the other ends of such rods are connected to each end of a cross
bar mounted on a stud fixed to any convenient part of the loom. When one of the
levers is operated by the ordinary mechanism and moved back its rod is pulled, the
cross bar is turned on its stud, and the other correcting rod draws its lever in a
reverse direction to the first lever and vice versa, so that the motion is positive.

Improvements in or connected with Loose Reed and Picking
Motions of Looms.
We HERBERT ANDERTON FOSTER Manufacturer and STEPHEN HOLROYD
Foreman, both of Black Dike Mills Queensbury in the County of York, 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
"
Firstly To improvements in loose reed motions of looms for weaving, the object
being to stop the loom when a shuttle is caught in the race, before the "beat up
is made, thus preventing damage being done to the warps or shed.
Secondly-To improvements in pick and pick looms where levers are employed
for controlling the sliding of the picking tappets on their shaft wherein we employ
apparatus for preventing more than one of the said levers from being operated or
operating on the picking tappet at one and the same time, thus obviating breakage
or faults in the weaving.
Such being the nature and object of our said invention the following is a
complete description of same, reference being had to the accompanying drawings in
which :-
Fig. 1 is a front elevation of part of a loose reed motion of a loom having our
improvements applied in connection with such motion, similar apparatus being at
each end of the loom.
Fig. 2 is an end view of Fig. 1.
Fig. 3 is an end elevation of the improvements applicable to pick and pick looms.
Fig. 4 is a plan view of part of Fig. 3.
According to this invention and referring firstly to the loose reed motion.
The ordinary reed and reed case 1 are employed, the reed case being connected
to the stop rod 2 by fingers 3 as usual.
Arms 4 at or near each end of the stop rod 2 extend to the front of the loom so
as to form handles 5 by which the reed case can be moved and opened or closed by
the operative. On each of the said handles or connections 5 which are near each
end of the loom we mount runners 6. Below the runners 6 and fixed to each
sword 7 is a stud 8 on which is loosely mounted a curved lever 9 one end 10 of
which rests against the back of the runner 6 above mentioned, the other end 11
being cranked upwards and extending towards the front of the loom. A second
curved lever 12 mounted on the same stud 8 as the first lever 9 rests against the
front of the before mentioned runner 6 and the other and lower end of this lever 12
is connected by spiral spring 13 to any fixed part of the loom.
Mounted loosely on a stud 14 fixed on each sword 7 is a beak or finger 15 which
rests on the "cranked end" 11 of the first mentioned lever 9. At or near and
extending the length of the front of the loom is a bar 16 free to move in slides, and
on this bar 16 which is connected with the ordinary stop handle are the frogs 17.
When a shuttle is caught in the race, and the reed turned in its cap, the stop
rod 2 makes a part revolution as ordinary and the runners 6 on the two handles 5
move clear of the curved part 10 of the first mentioned lever 9 which by gravitation
and through the action of the spring 184 will turn on its stud as indicated by the
dotted lines A Fig. 2 and the cranked ends 11 of same are thereby lowered, as are
also the beaks or fingers 15 resting thereon, so that as the slay moves forward to
the "beat up" the fingers or beaks 15 come in contact with the "frogs" 17 (or a
recess formed in same) and the latter and the sliding bar 16 are moved and the
loom is "knocked off," and as the sliding bar 16 has only a limited amount of
movement, when this limit is reached the slay is prevented from moving forward
and no "beat up" is made. The second mentioned lever 12 and spring 13 hold
°

page_text: the reed case in its normal position until a shuttle is caught in the race and the
resistance of the spring overcome. The beaks or fingers 15 being held by the
curved levers 11, pass above and clear the frogs 17 when the shuttle boxes.
Referring now to Figs. 3 and the improvements in pick and pick looms consists
in connecting the levers 18, 18 which control the sliding tappets as follows:-
Each of the said levers 18, 18 has a light rod 19 attached to it and the other
ends of such rods 19 are connected to each end of a cross bar 20, (see Fig. 4)
mounted on a stud 21 in a bracket 22 fixed to any convenient part of the loom.
When one of the levers 18 is operated by the ordinary pattern mechanism and
connections and thereby moved; its rod 19 is pulled, the cross bar 20 is turned on
its stud 21 and the other connecting rod 19 draws its lever 18 in a reverse direction
to the first lever and vice versa, so that the motion is positive.
A light spiral spring 23 is placed on the stud 21 above and resting on the bar 20
so that the latter is steadied and prevented from moving until one of the rods 18 is
operated upon.
Having now particularly described and ascertained the nature and object of our
said invention, and in what manner the same is to be performed we declare that
what we claim is :-
:-
1. The cranked lever 9 and beak 15 constructed substantially as described and
illustrated when combined with the operating parts of a loose reed motion as and
for the purpose herein described.
2. The parts illustrated by Fig. 4 and as such appear in Fig. 3 for controlling
and ensuring positive motion and action of the levers 18, 18 of the picking tappets.
