Improved Means or Apparatus for Governing the Action of the
Pattern Surfaces and for Putting In and Out of Action the Pulling
or Lifting Catches of Circular Boxes in Looms for Weaving.
We, THOMAS MARSDEN and ISAAC THOMPSON, both of Holme Mills, Nelson, in the
County of Lancaster, Manufacturers, do hereby declare the nature of this invention to
be as follows:-
This invention relates to the employment of two or more pattern cylinders,
governed by another pattern cylinder, which is only actuated at comparatively
distant intervals; and is designed to reduce the length of the pattern surfaces, now
required, to weave long and complicated designs. The governing cylinder is provided
with two feelers or levers, which are acted upon by peg-lage or cards, so as to remove,
or apply, the actuating catches of the two cylinders in accordance with the order of
motion desired. The governing cylinder is actuated through the medium of a vertical
traversing catch, which is only in contact with the said cylinder, when so allowed by
a notch on each of the pattern surfaces of the two other cylinders being brought into
position, to raise simultaneously two levers, which previously held the traversing
catch out of contact with the teeth of a ratchet or pegged wheel on the governing
cylinder. This cylinder is only actuated to the extent of one tooth to determine
which of the two pattern cylinders will, for the time being, be actuated. When it is
desired to weave a ground pattern, two notches on the two pattern surfaces are again
presented, to release the traversing catch, to actuate the governing cylinder to the
extent of another tooth only, so as to raise, by means of the peg-lags, both feelers, and
withdraw both the actuating catches of the two cylinders, until another change in the
pattern is to be woven.
The invention further relates to means for putting in and out of action the lifting or
pulling catches of circular box motions, and consists in dispensing with the vertical
arms of the bell crank levers, the horizontal arms of such levers being made to actuate
the pattern cylinders as before.
From the said horizontal arms are suspended vertical rods, which act upon the
horizontal arms of two small bell crank levers, the vertical arms of which act upon
the lifting or pulling catches in a similar manner to those dispensed with.

COMPLETE SPECIFICATION.
Improved Means or Apparatus for Governing the Action of the
Pattern Surfaces and for Putting In and Out of Action the Pulling
or Lifting Catches of Circular Boxes in Looms for Weaving.
We, THOMAS MARSDEN and ISAAC THOMPSON, both of Holme Mills, Nelson, in the
County of Lancaster, Manufacturers, 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 more particularly to means for actuating revolving shuttle
boxes, and consists in the employment of pattern surfaces or cylinders governed by
another cylinder, which is only actuated at distant intervals, and is designed to
reduce the length of the pattern surfaces now required to weave long and complicated
designs.
The governing cylinder is provided with two feelers or levers, which are acted upon

page_text: by peg-lags or cards, so as to remove or apply the actuating catches of the two
cylinders in accordance with the order of motion desired. The governing cylinder is
actuated through the medium of a vertical traversing catch, which is only in contact
with the said cylinder when so allowed by a projection on each of the pattern surfaces
of the two other cylinders being brought into position to raise simultaneously two
levers which previously held the traversing catch out of contact with the teeth of a
ratchet or pegged wheel on the governing cylinder.
This cylinder is only actuated to the extent of one tooth at a time to determine
which of the two pattern cylinders shall, for the time being, be actuated. When it is
desired to weave a ground pattern two projections on the pattern surfaces are again
presented to release the traversing catch to actuate the governing cylinders to the
extent of another tooth, so as to raise by means of the peg-lags a feeler, and withdraw
one of the actuating catches from one of the cylinders until another change in the
pattern is to be woven.
The invention further relates to means for putting in and out of action the lifting
or pulling catches of circular box motions, and consists in dispensing with the vertical
arms of the bell-cranked levers, the horizontal arms of such levers being made to act
upon the pattern cylinders as before. From the horizontal arms of the said levers
are suspended vertical rods which act upon the horizontal arms of two small bell-
cranked levers, the vertical arms of which act upon the lifting catches in a similar
manner to those dispensed with. The lifting catches are connected as usual to the
horizontal levers actuating the two clawker rods, one on each side of the studded or
pegged wheel fixed to the axis of the series of shuttle boxes to cause them to make
partial rotation in either direction as may be determined by the pattern surfaces.
In the accompanying drawings Fig. 1 shews an outline end view of a portion of a
loom with our improvements applied. Figs. 2 and 3 are respectively front and back
views, and Fig. 4 a plan of the same. Figs. 5, 6, 7 and 8 are detached views of parts
of mechanism hereinafter mentioned.
The barrels A and B are provided with two chains of pattern surfaces composed as is
well known of a certain number of rectangular cards or metal plates of the same size
as the facings of the barrels A and B.
Perforations or holes are formed in the cards, which correspond with projections
formed on each side of the barrels by which they are carried forward. Other holes or
perforations are formed as in the ordinary cards to determine the order of motion of
the rotating shuttle-boxes. The cards act upon the levers C, C³, C and C³, so as to
cause the stampers D attached to each of the said levers to actuate the inverted
L shaped levers D1 and D2 pushing them against hooked levers E and E¹ to move
forward or backwards the rotating boxes.
The barrels A and B may be actuated intermittently by the catches G and G'
jointed to the levers C and C. These catches have in usual practice, been made to
actuate the respective barrels to the extent of one card every two picks, consequently
a considerable number of cards have been required when weaving long and com-
plicated patterns or when weaving a considerable length of the same fabric of the
same colour.
We will now describe our invention as relates to the reduction of the number
of cards carried by the two pattern barrels, which is effected by removing.
automatically the catches G and G¹ from the ratchet wheels of such barrels, which
for the time being, will become inoperative, instead of repeatedly presenting a series
of cards having perforations and indications whilst weaving with one shuttle with
the same colour of weft for a considerable length of fabric.
For this purpose we employ the barrel H provided with an endless chain of peg-
lags which act upon feelers or levers U and V. Each feeler or lever has two arms
one projecting horizontally over the surface of the peg-lags K and the other projecting
downwards and terminating horizontally at U₁ and V₁, where they are connected by
cords J to their respective catches G and G¹.
By referring to Fig. 4, it will be seen that two levers M and N are located between
the levers C¹ and C.

page_text: The levers M and N are each provided with bent arm M2 which are made to act upon
a vertical traversing catch O, carried at one end of the lever P vibrating on stud Q
and actuated by the up and down motion of the ordinary lifting bar S. In Fig. 4, it
will be also seen, that the extremities of the levers M and N are cranked round the
ends of the adjoining levers C¹ and C.
When the machine is in operation, the barrels A and B are actuated together by
the catches G and G¹ when the pattern is of such a nature as to require them so to
act; but when one or other of the barrels A and B is desired to be at rest two
projections one on each chain of cards are simultaneously brought by the movement
of the two barrels under the cranked ends of the levers M and N, so as to remove the
bent arm M from the traversing catch O, which then engages with the ratchet or
pegged wheel fixed to the axis of the barrel H.
This barrel being thus turned to the extent of one tooth presents a peg under the
lever or feeler U and removes the actuating catch of the barrel A which would then
be at rest and inoperative until the peg on the barrel has been removed from the
feeler U. For this purpose, two projections on the chains of pattern surfaces are
again brought together under the feelers, or levers M and N when the traversing
catch is again set free to actuate the barrel H to the extent of another tooth,
bringing another peg under the feeler or lever V and at the same time removing the
peg from under the feeler or lever U. The barrel is then actuated, and the barrel B
is brought to a state of rest.
'
Assuming that both the barrels A and B have to be brought into action on the
next turn of the barrel H, no pegs whatever are presented to the levers or feelers U
and V.
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 is :-
1. In governing or operating rotary shuttle boxes, the mode or method for the
reduction of the length of pattern surfaces, substantially as described.
2. The combination of mechanical parts, comprising barrel H, feelers M, N, U
and V operating subtantially as described for the purpose specified.
3. The combination of mechanical parts, comprising stampers or rods D, and the
inverted shaped levers D1 and D³ substantially as described for the purpose
specified.
