Improvements in Mechanisms for Operating the Shuttle-boxes,
Weft-stop Apparatus, and Heddles of Looms.
We, RICHARD LONGDEN HATTERSLEY of Keighley in the County of York,
Machine Maker, and SIMEON JACKSON, of the same place, Mechanic, do hereby
declare the nature of this invention to be as follows, that is to say :—
It relates firstly to improvements in the arrangement and construction of the
several parts forming the operating mechanism of shuttle-boxes of looms of
the class known as rising or drop-boxes whereby shuttle-boxes having six or even
Beven, eight or nine different compartments may be employed and operated
to bring any one of their said compartments in line or level with the shuttle race
on the lay at any predetermined time and that with precision while by this arrange-
ment and formation of parts all the said operating mechanism necessary for
imparting motion to or for effecting the movements of each tier of shuttle-boxes that
is on each side of the lay may be mounted on one and the same side of said loom.
The second part of our invention relates to weft-stop mechanisin of looms and
consists of arranging and forming the several parts of this mechanism in such a
manner that the motion of the loom on the breakage or failing of the weft is
abruptly arrested and that before the slayboard or lay has moved sufficiently far
to beat in the broken shot of weft, while by a peculiarity in this arrangement the
disengaging of the driving mechanism of the loom is and can only be effected by
the weft-stop mechanism at one place or in one position in the path of motion of
the lay, by which peculiarity the driving mechanism is perfectly free to be thrown
into gear or otherwise operated by the weaver as is or may be from time to time
desired.
The third part of our invention has reference to the shedding mechanism of
loons of that class in which the jack-levers carry their operating catches and more
especially to that style of jack-lever which is mounted on the outside of the end
frame of the loom and extends from the heddle connecting rods or cords above the
loom to those below the loom said arrangement of jack-lever and shedding
mechanism being known as of the "shut-shed" type, and our invention consists of
an arrangement of means whereby the pattern surface consisting of logs and pogs
may be employed instead of the pattern surface forined by metal bowls and links
or chains.
The object of the first part of this invention is attained by making use of the
arrangement of continuously rotating toothed segments, which operate toothed
crank-wheels for moving the box operating levers, that is well known and at
present extensively in use, however when employing these levers and mechanisms
for operating a shuttle-box of six compartments we arrange their leverage so that
by using two of the said levers we may by extra bowl and chain or lever and rod
connections operate an intermediate lever mounted upon the bottom or low box-
lever, in such a manner or for such a distance as shall be necessary to move the
shuttle-box the space of one of its compartments for each movement of each of
these levers, while we employ a third lever of such dimensions as shall by each of
its movements move the said intermediate lever so that the shuttle-box may be
moved the space of three of its compartments in this manner auy of the com-
partments in said shuttle-box may be brought level with the lay at any time
.desired.
When shuttle-boxes having seven, eight or nine compartments are to be operated
a fourth lever of the kind above described and baving leverage proportionately
with the third lever above named is employed, and this lever is joined by other

page_text: lever and rod or bowl connections to the intermedinte lever which it operates in
such a degree as to move the shuttle-box the space of three of its compartments
80 that by the aid of first, second and third levers this fourth lever can move the
aliuttle-box, whether same has seven, eight or nine compartments, so that any
one may be brought at any time level or in line with the upper surface of the lay.
The arrangement of the levers above described is effected in such a manner
that they shall occupy only a limited space laterally so that the whole series
together with a similar serics for the shuttle-box on the other side of the loom,
may be mounted on one side of the loom by which means both of these series are
governed by one and the same pattern surface, said pattern surface preferably con-
sisting of peg-lags revolving around a pattern barrel as is well understood. And
the said arrangement is also accomplished by the levers moving in such respective
and relative directions as shall enable the said pattern-surface to bear, only one
meaning for each of its pegs or in other words enabling it to perform its functions
by each peg being to indicate for a rise in the shuttle-box and a blank for a fall
in same or vice-versa.
The object of the second part of our invention is attained by making use of the
weft-fork mechanism of the class wherein the weft-fork is situated at about the
central part of the lay, the said weft-fork receiving its vertically oscillatory motion
by a vertical rod hinged out of centre with the said lay as is well understood, said
vertical rod reciprocating a moveable catch-block that is retained by the hooked
bracket carrying the prongs of the fork, when the weft breaks or fails to arrest
the descent of this fork and hooked bracket, and to this arrangement of mechanism
we add a lever and mount it upon the lay to operate in connection with this catch-
block in such a manner that it is raised out of position or allowed to remain in
position for striking a tumbling lever when the lay moves towards the front of the
loom, as the case may be hy weft being present or absent.
By the oscillating or tumbling of this tumbling lever, a finger on a rod that
operates the loom's disengaging mechanism is moved so as to effect this disengage-
ment while by said tumbling lever moving to accomplish this object the lever on
the lay has moved clear of same so that by its peculiar shape it (said tumbling
lever) may return to its normal position by which means none of the loom's driving
mechanism is in any way prevented or held from being operated as the weaver
may desire.
We attain the object of the third part of our invention by mounting upon a
shaft, carried by the framework of the machine, a series of intermediate levers
which we arrange to be in operating contact with the series of catches mounted
upon the series of jack-levers, each of said catches having its corresponding inter-
mediate lever. The lower surface or edge of each of these intermediate levers is
made of a suitable concave form for contact with the pegs of the peg-lags which
operate beneath it, while on the upper surface of each of said levers, a projection
or protuberance is formed for contact with its corresponding catch mounted upon
the jack-lever, by which means all the wear incident to or that must necessarily
follow the bearing or resting of these catches upon their levers when travelling or
sliding thereon during their reciprocatory movement with the jack-levers,
stood by these said intermediate levers, without which (since said reciprocatory
motion of the catches entails such an amount of wear on anything that is used to
support them) wooden lags and pegs could not be used except by incurring cou-
siderable disadvantages.
with-
The employment of the intermediate levers above, described does not interfere
with the using of metal bowls and chains whenever these are desired, but enables
these metal chains and peg-lags to be interchangeable.

Improvements in Mechanisms for Operating the Shuttle-boxes,
Weft-stop Apparatus, and Heddles of Looms.
We RICHARD LONGDEN HATTERSLEY of Keighley in the County of York,
Machine Maker, and SIMEON JACKSON, of the same place, Mechanic, 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, that is to say :-
It relates firstly to improvements in the arrangement and construction
of the several parts forming the operating mechanism for the shuttle-boxes of
looms of the class known as rising or drop-boxes whereby shuttle-boxes having
six or even seven, eight or more different compartments may be employed and
operated to bring any one of these said compartments in line or level with the
shuttle race on the lay at any predetermined time and that with precision, while by
this arrangement and formation of parts all the said operating mechanism necessary
for imparting motion to or for effecting the movements of each tier of shuttle.
boxes that is on each side of the lay may be mounted on one and the same side of
Baid loom.
The second part of our invention relates to weft stop mechanism of looms aud
consists of arranging and forming the several parts of this mechanism in such a
manner that the motion of the loom on the breakage or failing of the weft is
abruptly arrested and that before the slayboard or lay has moved sufficiently far to
beat in any broken shot of weft, while by a peculiarity in this arrangement the
disengaging of the driving mechanism of the loom is and can only be effected by the
weft-stop mechanism at one place or in one position in the path of motion of the lay
by which peculiarity the driving mechanism is perfectly free to be thrown into
gear or otherwise operated by the weaver as is or may be from time to time
desired.
The third part of our invention has reference to the shedding mechanism of
looms of that class in which the jack-levers carry their operating catches and more
especially to that style of jack-lever which is mounted on the outside of the end
frame of the loom and extends from the heddle connecting rods or cords above
the loom to those below the loom said arrangement of jack-levér and sliedding
mechanism being known as of the "shut-shed "type, and our invention consists of
an arrangement of means whereby the pattern surface consisting of lags and pegs
may be employed instead of the pattern surface formed by metal bowls and links or
chains.

Fig. 1 is end elevation of a portion of a loom shewing the application thereto of
our improved mechanism for operating the shuttle-boxes.
Fig. 2 is a top view enlarged scale shewing certain of the levers and other parts
illustrated by Fig. 1.
Fig. 3 is also a top view enlarged scale shewing certain levers and parts illustrated
by Fig. 1.
Figs: 4 and 5 are similar views to Figs. 2 and 3 respectively but are illustrative
of added parts hereinafter fully described.
Figs. 6, 7, 8, 9, 10, and 11 are side elevations of the levers and bowls for operating
the tier of shuttle-boxes six of said shuttle boxes constituting said tier and shew the
several relative positions assumed by these parts when moved to place the said tier
of shuttle-boxes at its several elovations, the framework in each figure being
omitted.
Figs. 12, 13, 14, 15, 16, 17, 18, 19 and 20 are similar views to Figs. 6 to 11 but
illustrate the varied positions of the several parts when their tier of shuttle-boxes

page_text: Figs. 21, 22 and 23 are end front and top views of a sufficient portion of a loom to
shew the application thereto of our improved weft-stop mechanism.
Figs. 24 and 25 are side and end olevations of a portion of loom beddle operating
mechanism with our improved parts applied.
Similar letters and figures of reference indicate similar parts throughout the
several views.
The object of the first part of this invention is attained by making use of the
arrangement of continuously rotating toothed segments a and a which operate
toothed-crank wheels for moving the box operating levers cc, that is well known
and at present extensively in use, however when employing these levers c c for
operating a shuttle box or tier of shuttle boxes of six compartments as at
d, d', dd, d and we arrange their leverage so that by using two of the said
levers cc we may, by the chaine and bowl, operate an intermediate lever
mounted upon the bottom or low box-lever 4, in such a manner or through such a
space or distance as shall be necessary to move the tier of shuttle-boxes the space
of one or other of its compartments d, d'; d², d³, d', or d for each movement of each
of these levers c.ore, while we employ a third lever c of such dimensions relatively
with the levers.cc as shall by each of its movements operate or move the said
lever g so that this shall operate or move the lever h to move said tier of shuttle-
boxes the space of three of its compartments d, d', d³, d³, d' or d³ in this manner any
of the said compartments may be brought level with the lay at any time desired
(as the lever ‹ is, at each of its movements, required to move, by means of its chain,
the shuttle-box the space or three of its compartments, a counterbalancing spring 5
is employed for assisting it in its said movements) the varied positions assumed by
these several levers and parts being shewn by Figs. 6 to 11 inclusive, that is to say,
when the uppermost compartment is level with the lay then the parts are in their
respective positions shewn by Fig. 6, when the next compartment d' is level with
the lay then the respective position assumed by these parts are shewn by Fig. 7
and in like manner when the compartments dª, d², d' and-d are respectively brought
into this relative position with the lay then Figs 8, 9 10 and 11 respectively shew
the several positions of these operating parts.
When shuttle-boxes having seven, eight or nine compartments are to be operated,
a fourth lever k, of suitable dimensions relatively with the lever g, is employed,
and this lever is joined by the chain which is fixed at 6 to the framework and
passes-over the pulley 8 carried by the lever c', over the fixed pulley 7, around the
pulley 8 carried by the lever g back over the pulley 7, around the pulley 8 on the
end of the lever k to have its other end also fixed at 6, thus it operates the lever g
in such a degree as to move the shuttle box the space of three of its compartments
so that by the aid of the levers c, c, c and g this fourth lever & can move the shuttle
box, whether same has seven, eight or nine compartments, to bring any one of
these compartments level or in line with the upper surface of the lay at any time,
the varied positions assumed by the several levers and parts when each respective
compartment successively from the lowest to the highest is in line with the lay,
being shewn by Figs. 12 to 20.
The relative positions of the several sets of levers above described is such as to
bring same into a comparatively small space laterally as is shewn by Figs. 2, 3, 4,
and 5, so that the whole series together with a similar series, marked with the same
letters but accompanied with an asterisk, for operating the shuttle-boxes on the
opposite side of the loom, may be mounted on one and the same side of said loom,
by which means both of these series are governed or controlled by one and the
same pattern surface as at me, said pattern surface preferably consisting of peg-lags
although pattern cards n are shewn, the same being arranged to revolve around the
barrel o as is well understood.
By the arrangement of levers as hereinbefore described and by their several
chain connections being as shewn in the drawings, it is only necessary for said'
pattern surface to bear one meaning for each of its pegs or blanks on the Ings or
cards, or in other words each of said pegs or blanks indicates for a rise in the

page_text: shuttle-box while where there is no peg in the lags or where there is a hole in the
cards then the shuttle-box is caused to fall or descend, or vice versu.
The object of the second part of our invention is attained by making use of the
weft-fork mechanism of the class wherein the weft-fork p is situated at about the
central part of the lay, the said weft-fork receiving its vertically oscillatory
motion by a vertical rod hinged at ront of centre of movement about which the
said lay q oscillates as is well understood. This rod imparts reciprocatory motion
to the blocks in a somewhat vertical direction, and this blocks is arranged to be
caught by the hook ', on which the prongs p are mounted to form the weft-fork,
whenever said prongs are allowed, by the breakage or failing of the weft, to
descend low enough for said hook p' thus to lay hold of the block s.
On the lay and in proximity with the blocks we hinge he levert its fulcrum
being at while its extending, arms and reach into contact with the blocks on
one side and so far in the other direction as the path of motion of its extreme outer
end will fall across a tumbling lever hinged on the bracket »' carried by the
front rail u of the loom.
1
As is before stated when the weft fails the block is arrested in its descent by
reason of the hook pl being allowed to fall low enough to lay hold thereof, so that said
blocks is thus prevented from causing the arm of the levert to descend to move
its other arm out of the path in which the lever lies, consequently as the said
lever is moved towards the front of the loom by the lay travelling to beat in the
weft, said lever arm t³ will strike the lever causing its arm to move the lever v
in a downward direction. This movement of the lever partly rotates the rod
which by the employment of the well known other parts operates the mechanism
for arresting the motion of the loom. When the weft is present or in continuity
then the prongs are arrested by it and so the hook p¹ does not lay hold of the
blocks hence this is allowed to descend by gravity sufficiently far to operate
the levert, by overcoming its retracting spring, to raise its arm 3 out of this
path in which the lever lies, in this manner allowing the loom to continue in
motion.
By the lever being arranged to oscillate about its central pin, as the lay
continues its forward motion, although the lever arm may for a space be in
contact with its (said lever u) yet it finally moves clear of it, thus allowing it by
gravity to return to its original normal position by which means none of the other
parts for operating the loom's driving mechanism are in any way prevented or held
from being moved or operated as the weaver may desire.
We attain the object of the third part of our invention by mounting upon a
shaft 1, which is carried by the framework of the machine (said framework being
omitted from the drawing so that the other parts might be more clearly illustrated),
a series of intermediate levors 2 which we arrange to be in operating contact with
the series of catches 3 mounted upon the series of jack-lovers 4, each of such
catches having its corresponding lever 2. The lower surface or edge x of cach
of these levers 2 is made of a suitable concave or slightly curved form for contact
with the pegs 15 of the peg-lags 16 which operate beneath it upon their cylinders 17
while on the upper surface of each of said levers 2 a projection or protuberance y
is formed for contact with its corresponding catch 3 mounted upon the jack-lover 4,
by which means all the wear incident to or that must necessarily follow the bearing
or resting of these catches upon their levers when travelling or sliding thereon
during their reciprocatory movement with the jack-lover 4, is withstood by these
said intermediate levers 2, without which (since said reciprocatory motion of the
catches 3 entails a similar amount of wear on anything that is used to support
them) wooden lags and pegs could not be used except by inourring a considerable
amount of disadvantage.
The employment of the intermediate levers above described does not interfere
with the using of metal bowls and chains whenever these are desired, but enables
these metal chains and peg-lags to be interchangeable.

page_text: 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. The arrangement and combination of levers, bowls and chains for effecting
the movements of a shuttle-box having six compartments substantially as herein
specified:
1.
2. The arrangement and combination of levers, bowls and chains for effecting the
movements of a shuttle-box having seven, eight or nine compartments substantially
as herein set forth and illustrated by the accompanying sheets of drawings.

which are arranged to be stationary so far as regards any movements other than
that about their fulcrum pin, with the series of reciprocating catches and pattern
