PROVISIONAL SPECIFICATION
Improvements in or appertaining to the Picking Motion of Looms
for Weaving.
We, RICHARD LONGDEN HATTERSLEY, of North Brook Works, Keighley, in
the County of York, Machine Maker, and SIMEON SCHOON JACKSON, of the
une address, Manager, do hereby declare the nature of this invention to be as
follows:-
This invention relates to that class of picking motion, wherein the picking cones
or levers are loosely mounted on the picking shafts, and where dogs are employed
for coupling the picking cones or levels to the picking shafts
In this arrangement, the dogs are attached to the horizontal arms of bell clank
levers, such levers being coupled together from their vertical aims.
The gearing
of the dogs, with the picking cones or levers, is regulated from the box motion of
the loom, by a rising and falling iod operating on one of the bell crank lovers
against spring pressure, so that, as one dog is lifted out of gear, the dog at the
opposite side is let into gear with its picking cone or lever, and vice versa
The object of our invention is, to provide a simple arrangement of parts for
stopping the action of the picking motion from the dobby, so that when the dobby
is put out of operation, or prepared for reversion for the purpose of lagging back
or other causes, the picking motion is at the same time rendered inoperative.
Under ordinary working conditions one or the other of the dogs is in gear, so
that the distance between the vertical ends of the bell crank levers is always the
same. If, however, the vertical ends of the bell crank levers be forced further
apait, both the dogs attached to then horizontal ends will be held up and kept out
of gear.
In order to effect this, we pivot an additional lever to one of the vertical arms
of the bell crank levers. This lever is placed at a slight angle with the horizontal.
To the inside end, wo couple the connecting rod to the other bell crank lever, and
to the opposite end, we couple a rod connected at its other end to the hand lever
for reveising the dobby, so that, when this hand lever is moved, the rod connected
to the picking motion as above described is raised.
This operation causes the additional lever to assume a horizontal position, thus
increasing the length of the connection between the vertical arins of the bell crank
loveis, aud forcing them further apart, thereby preventing the dogs coupling the
picking levers to the picking shafts.

We, RICHARD LONGDEN HATTERBLEY, of North Brook Works, Keighley, in
the County of York, Machine Maker, and SIMEON SCHOON JACKSON, of the
same address, Manager, do hereby declare the nature of this invention and m
what manner the same is to be performed, to be particularly described and
ascertained in and by the following statement
-
This vention relates to that class of picking motion wherein the picking cones
oi levers are loosely mounted on the picking shafts, and wherein dogs are employed
for coupling the picking cones or levers to the picking shafts.
In this arrangement the dogs are attached to the horizontal aims of bell crank
levers, such levers being coupled together from their vertical aims.
The gearing
of the picking cones or levers to their respective picking shafts is regulated from
the box motion of the loon, by a rising and falling rod operating on one of the
bell crank levers against spring pressuie, so that, as one dog is lifted out of gear,
the dog at the opposite side is let into geni, and vice-versa.
The object of our invention is to provide a simple arrangement of parts for
stopping the action of the picking motion from the dobby, so that when the dobby
is put out of operation, or prepared for reversion for the purpose of lagging back,
or other causes, the picking motion is at the same time rendered inoperative.
Under ordinary working conditions one or the other of the dogs is in gear, so that
the distance between the vertical ends of the bell crank levels is always the same.
If, however, the vertical ends of the bell cıank lovers be forced further apart, both
the dogs attached to their horizontal ends will be held up and kept out of gear.
In order to effect this, we pivot an additional lever to one of the vertical arms
of the bell crank levers. This lever is placed at a slight angle with the horizontal.
To the inside end, wo couple the connecting rod to the other bell crauk lever, and
to the opposite end we couple a rod connected at its other end to the hand lever for
reversing the dobby, so that, when this hand lever is moved, the rod connected to
the picking motion as above described is raised.
This operation causes the additional lever to assume a horizontal position, thus
increasing the length of the counection between the vertical arms of the bell crank
levers, and forcing them further apart, thereby preventing the dogs coupling the
picking levels to the picking shafts.
In order to more fully explain our invention, we append hereto two sheets of
drawings marked with letters of reference.
Fig. 1 of such drawings shows the front view of the picking motion of a loom
arranged according to this invention, and
Fig. 2 is an end view of same, or section on line a. b
A and A' are the picking cans mounted on the shaft B in the usual manner.
Cand Care the piching shafts, to which the picking sticks are attached,
D and D' the picking cones loosely mounted on the shafts C and C' respectively,
and E and E sliding dogs which engage with slotted collars E and E³, fixed to the
picking shafts, whereby the cones are alternately coupled to their respective shafts.
The dogs E and E' are respectively operated upon by the bell crank levers F
and the vertical arms of which are connected together, so that, when the
horizontal aim of one is raised, the other is lowered.
The bell crank lever is connected by a rod G and levers G' and G to a rod G³
which is coupled to the box motion of the loom, so that, on the upward movement
of the said rod G' the lever F is operated to raise the dog E, and the lever Fis
operated to lower the dog E', so that the picking cone D is put out of gear with
its picking shaft and the picking cone D into gear with its picking shaft.

the rod G³, the action of the picking coues again reversed.
is
Ilitherto the vertical ends of the levers F and F have been coupled by a rigid
rod, and the mechanisin and operations above-described are well understood.
In order, however, to raise both the dogs E and E' at the same time, by means
of the same lever with which the dobby is prepared for a reversion of motion, we
pivot, to the vertical end of the lever F, an additional lever J which is placed at
a slight angle with the horizontal. To one end of this lever, we couple a rod K
which is operated by the hand lever L for preparing for a reversion of the dobby,
and to the other end of the lever J we couple the rod M, this latter being also
coupled to the vertical end of the bell crank lever F¹.
It will be seen that, by raising the rod K, the lever J will assume a more
horizontal position and thereby force the vertical arms of the bell crank levers F
and F further apart, thus raising both the dogs E and E' and causing the picking
motion at both sides of the loom to be inoperative.
Having now particularly described and ascertained the nature of our said inven-
tion, and in what manner the same is to be performed, we declare that what we
claim 18:
In a loom picking motion, the coupling rod M, lever J, and rod K connected to
the hand lever L, all arranged substantially as shown and described and for the
purpose herein set forth.
