fork. and Treading Motions and the Construction of Shuttle
Boxes of Looms for Weaving.
We RICHARD LONGDEN HATTERSLEY of Keighley in the County of York,
Machine Maker, and JAMES HILL, of the same place, Overlooker, do hereby
declare the nature of our invention for IMPROVEMENTS IN THE DRIVING, BRAKE,
PICKING, STOP ROD, WEFT FORK AND TREADING MOTIONS AND THE CONSTRUCTION
OF SHUTTLE BOXES OF LOOMS FOR WEAVING to be as follows :—
Our invention consists of an improved arrangement of the several parts forming
the driving, brake, picking stop rod, weft fork and treading motions and also of an
improvement in the construction of rising shuttle boxes of looms for weaving; the
said invention being explained by the following description:-
Firstly, relating to the arrangement of the driving & brake motions. Upon the
outer end of the top shaft of the loom we mount loosely so as to revolve and slide,
a driving pulley, having one of its outer sides formed so as to receive a band or
facing of leather or other material which is fixed to it. Upon the same shaft and
in close proximity with the before mentioned driving pulley is rigidly mounted a
circular metal plate or disc, which when turned gives motion to the loom and which
has each of its sides polished or otherwise prepared so as to form a suitable surface
for contact with the leathered facing of the before named driving pulley on one
side and the leathered facing of a brake lever on the other side. The said driving
pulley requiring to be pressed, by the weaver, into contact with one side of the said
disc, through the medium of suitably formed lever, connecting rod, strong spring (80
as to allow of a slight yield as occasion may require) and setting on handle, when
the loom is required to be driven; and the aforesaid brake lever, being connected
by appropriate parts to the same handle, when the motion of the loom is required
to be arrested, is operated upon simultaneously with the said driving pulley and
presses its leathered or prepared surface against the other side of the before,
mentioned disc and so almost instantly arrests the motion of the loom.
When driving with double gear we mount the driving pulley and friction plate
previously described, upon the barrel or elongated boss of a toothed wheel which
revolves loosely on the top or crank shaft and which is in gear with another
toothed wheel keyed to the low shaft of the loom, from which part revolving
motion is imparted by suitable gearing back again to the said top shaft.
Secondly the arrangement of the picking and stop rod motions. A tappit
commonly known as a picking tappit is keyed upon the low shaft at an appro-
priate distance from the inner side of the end frame of the loom, beneath it and
in a suitable position so as to work in connection with it, is a cone or picking ball,
which revolves on a stud rigidly fixed to a horizontal shaft stretching from the

page_text: back to the front part of the loom; the said shaft being carried at its end nearest
the front of the loom, by a swivel-joint hinged to a bracket, fixed to the end frame
of the loom, its other end being carried by the arm of a lever which is fulcrumed
to a stand, also fixed to the end frame of the loom; the other arm of the said lever
forming a segment, in which is made a recess or notch, which receives the end of a
rod, the said rod being pressed into the recess by a spring of suitable strength,
which together with the rod is carried by the stand carrying the segmented lever.
From this it will be seen that should anything interfere to prevent the proper
working of the picking stick, when picking, which is directly and rigidly, during
that operation, connected by the use of leather strap, lever, catch and notched-
plate, to the horizontal picking shaft, the extra strain thereby put on the said
horizontal picking shaft, will overcome the pressure of the spring before-named and
force the rod out of the recess in the segment of the lever, thus the picking ball
together with the horizontal shaft will yield to the picking tappit and so prevent
any breakages.
The foregoing is a description of the picking motion on one side of the loom
only, but to carry or convey motion to the opposite side we mount rigidly on the
horizontal shaft, before named, a swape or small lever to which is binged a
connecting rod which reaches from the said swape to a similar one rigidly mounted
on another horizontal shaft, which is mounted but to revolve only in bearings fixed
to the other end frame of the loon; the said horizontal shaft stretching from the
back to the front part of the loom, carrying the notched plate, lever, catch and
leather strap as connecting parts to the picking-stick in the same manner as the
first named horizontal shaft, but as it is not operated on directly by the picking
tappit it is not required to be mounted in yielding bearings.
Or again we might make use of the horizontal yielding shaft with all its fittings,
bearings etc. on each side of the loom, but in this case we should require another
picking ball and tappit.
The working of the picking motion above described is controlled or indicated
upon in the following manner. Hinged in a suitable position, preferably to the
back part of the series of shuttle boxes, is a swell lever or what is commonly called
a sweller (the formation of which will hereafter be more fully described), one to
each compartment, each of which is pressed by a suitably shaped spring so that its
swell part projects into the said compartment.
Fixed to a short borizontal shaft which is placed directly in a line with the
stop-rod of the loom, is a lever or finger projecting upwards to come in contact with
the moveable end of the above named sweller in that compartment or shuttle box
in the series of shuttle boxes, which is level with the shuttle race, the said short
horizontal shaft being carried loosely at one end by a stand fixed to the frame work
in which the rising shuttle boxes slide and at the other end, also loosely, by the
elongated boss of a finger which is rigidly fixed to the end of the stop rod before
mentioned. Rigidly fixed to the same short horizontal shaft is another lever or
finger which projects downwards and under the frame work of the rising shuttle
boxes, the outer end of the said downward finger forming an incline, which is
brought into contact, by the forward motion of the slay board, with a projecting
piece fixed to the end frame of the loom, just at the time when the series of shuttle
boxes are changing position, and by the action of the said inclined end on the
projecting piece, the downward finger is kept from descending and consequently
the upward finger being rigidly attached to the same short shaft, is held from
contact with the series of swellers during the time that they, along with their series
of compartments of shuttle boxes, are changing position, thus the said upward
finger is held from moving too quickly backward and forward and is so prevented
from rebounding for a purpose which will hereafter be shewn. Attached to the
above named downward finger is a small connecting rod which extends downward
and is connected at its outer end to a small lever carried by a stand fixed to the end
frame of the loom, the said lever being connected by another connecting rod to
another lever rigidly fixed to one end of a long slender shaft which extends from

page_text: one side of the loom to the other and is carried by bearings fixed to the frame work
of the loom. To the other end of the said slender shaft is fixed a suitably shaped
lever which comes in contact with a pin fixed to the catch mentioned in a former
part of our description as being one of the coupling parts of the horizontal picking
shaft to the picking stick. Here let us mention that as the above named catch is
directly operated on by the sweller, as before described, if the before named
upward finger was allowed to rebound in passing from one sweller to another,
as the series of shuttle boxes were changing, this rebounding motion would be.
imparted to the said catch and so make its connection with the notched-plate very
uncertain; from this the use of the inclined end of the downward finger before
described will clearly be seen.
The actions of the foregoing parts are as follows; suppose that the slayboard is
moving to the back centre, that is, that it is approaching the place where the
picking motion should he put into operation for the purpose of throwing the
shuttle across the loom, in this position the inclined end of the above named
downward finger is drawn clear of the projecting piece fixed to the end frame of
the loom, so that the upward finger is then allowed to press against the end of the
sweller and should there be no shuttle in that compartment, the said sweller is
allowed to project to its greatest extent into the said compartment, consequently
by the upward finger following it; the downward finger is further lowered and by
the connecting rods, levers etc., the catch on the opposite side of the loom is lowered
into the notch of the notched-plate, thus the picking stick is connected to the
picking motion and a shuttle, should one be present in the shuttle box on the
opposite side of the loom to the one the sweller of which has indicated as being
empty, is thrown across the loom to fill the before named empty compartment, the
sweller in which is pressed out by the said shuttle on its arrival, and so the picking
motion is again disengaged by the catch being lifted out of gear with the notched-
plate.
Since the above described apparatus is fitted to each side of the loom it will be
clearly understood that the picking of the shuttle from either side may be effected
whenever desired.
The above named catch on both sides of the loom is also connected by suitable
parts, such as levers, connecting rods etc., to a handle which is used to operate on
the peg-lag cylinder so that when the motion of the said peg-lag cylinder is
reversed, for the purpose of accomplishing that which is commonly known as
"lagging-back," the said catch is held out of gear with the notched-plate, thus
the picking stick is prevented from picking during the said process of " 'lagging
back."
The stop rod is fitted to the back part of the slay board in the usual manner, and
stretches from the series of. shuttle boxes on one side of the loom to those on the
other, and has rigidly fitted to each of its ends a finger, mentioned in a former part
of our description as having an elongated boss, the said finger being formed to
overhang the downward fingers having the inclined ends, also before mentioned, on
each side of the loom respectively so that whenever the upward back finger is
moved or pressed back by the swellers in the shuttle box on either side of the
loom, the said stop rod is partially revolved by the finger which is rigidly attached
to it being lifted as the downward inclined finger rises. Welded or otherwise
rigidly fitted to the stop rod on the driving side of the loom only, is a projecting
piece which reaches in a forward direction, under the slayboard, and which is so
formed either in itself or by having another piece rigidly fitted to it, that when it
is in its lowest position one part of it will coune in contact with a projecting piece
fitted to the connecting rod of the setting on handle,. and the other part with a
buffer piece or "frog" and spring carried by a bracket fitted to the end frame of
the loom.
From this it will readily be understood that whenever the shuttle boxes or
compartiments which are level with the shuttle race or sherrboard on both sides of
the loom are empty, the projecting piece of the stop-rod will be in its lowest position

page_text: and that as it is brought forward with the slayboard the said projecting piece will
come in contact with the "frog," but as the other part of the above named
projecting piece will also be in its lowest position it also will come in contact with
the projection fixed to the setting on handle's connecting rod and so throw the
driving pulley out of gear with the driving disc, in the manner and with the
result fully described in the first part of our description, just before the former part
strikes the "frog"; thus the concussion and strain on the working parts incident to
the abrupt arrest of their motion when striking the "frog" previously to
disengaging the driving motion, will be entirely avoided.
shuttle on either side of the loon in position to push out either of the back fingers,
then the above named projecting piece will be raised clear of the frog and of the
projection fixed to the setting on handle's connecting rod and so the loom will
continue its motion.
But should there be a
Thirdly. Referring to our arrangement of the weft-fork motion; we use the
ordinary weft fork which is placed at or near the middle of the loom, having an
oscillating shaft mounted in bearings to the front of the slayboard and extending
along it to that part of the loom near the setting on handle's connecting rod, and
having at that part its usual other parts, but these latter parts are so arranged that
a forward finger in connection with them is made to strike or come in contact with
the projection fixed to the setting on handle's connecting rod, in time to stop the
loom when the weft is absent from the fork before the slay drives the broken pick
of weft into the piece being woven.
Fourthly with reference to the treading, our improved arrangements are in
connection with the treading motions commonly and well known as Hattersley's
Positive Dobbie. To each of the ends of the baulks or swing bars used in the said
dobbie, we hinge a catch in the usual manner; the said catch in our present
improvements being made or formed so as only to be pushed by the kniver or draw
bar with which it works in connection, and upon which it rests incessantly by
having its outer end extended a distance equal to that moved by the said kniver ;
the said outer end also passes under the stopper bar of the dobbie so that it is not
To the above
possible for the said catch to get out of position with the kniver.
named catch near its hinged end is also hinged another catch, which is made to be
drawn by the said kniver over which it also extends, and has formed on its upper
edge a catch which engages with the stopper bar of the machine when not working
or indicated upon by the pattern surface of the pattern cylinder; the outer end of
the said catch further extends and passes through a hole or loop formed in an
upright rod or needle, and is of a suitably inclined shape so that the said needle,
which has a loop at its top and bottom parts through which pass the top and
bottom catches respectively, might operate freely on one when the other is drawn
clear of it by the kniver. Fulcrumed to the frame work of the dobbie and in
suitable position are a series of levers corresponding in number to the series of
upright needles in the dobbie, one of the ends of each of the said levers reaching
under the end of one of the said needles, the other end extending over the pattern
or peg-lag cylinder. As will be easily understood, when a peg on the peg-lag
cylinder presents itself or is turned to the top of the said cylinder, any one of the
above named levers lying in its path of motion will be lifted at one end and
lowered at the other so that the needle with which it is in connection is also
lowered, so also are the ends of the catches carried by the said needle, but as only
one of the knivers or draw bars can possibly be in position to receive and act upon
one or the other of the said catches, the catch thus received is drawn by the said
kniver and so the heald is raised; while the other catch rests inactively, with the
smooth and uniform part of its bottom edge upon the other kniver, which was not
in position to receive and act upon it, until the peg-lag cylinder is further turned,
then, should another peg present itself under the same lever as before mentioned,
the catch which was inactive, on account of its kniver not being in position, but
which has now moved into position, is now received and acted upon by the said
kniver and so the heald is kept up; however if no peg is present when the peg-lag

page_text: cylinder is so turned, the before mentioned lever is allowed to lift the said catch
(the other catch being drawn with its inclined end clear of the loop in the needle)
out of position or connection with the kniver into position with the before
mentioned stopper bar, consequently the aforesaid heald is pulled down. Or to
dispense with the series of levers before mentioned we use a pattern card cylinder
and paper or other cards instead of peg-lags, the said paper cards operating directly
upou the bottom ends of the before described upright needles.
In order to bring the healds level with each other, for the purpose of taking up
broken ends of warp etc., we mount a shaft, in the framing of the machine, in such
a manner and position that when the said shaft is turned, by a handle attached to
it for that purpose; a rib, also attached to the said shaft, is brought to press upon
the ends of the series of levers, before described, and so put all the catches into
contact with the knivers, which by their movement accomplish the desired object.
A further modification in the arrangement and construction of the said heald
machine is to form the draw levers attached to the baulks with their outer ends
projecting upwards instead of horizontally as heretofore, by this we are enabled
more easily to couple them, by suitable other parts, to the healds.
Again the stopper bars in the said heald machine have previously been rigidly
fixed to the frame work thereof, but we now hinge them so that they will yield
when pressed in one direction and be rigid when pressed in the other, thus
preventing any breakages that might have been caused by any of the catches being
caught with their thickest or broadest part between the kniver and the said
stopper bar.
Fifthly. The construction of the rising shuttle boxes. Our improved method is
to form the whole of the shuttle box back part in one piece of metal, with openings
and projections for the insertion and fixing of each box shelf and sweller
separately, so that any one can be removed for repairs etc., without disturbing or
in any way interfering with the other. And in order to give additional firmness
to the said box shelves, we leave as much of the front outer edge of each box shelf
to project outwards unturned-up as the traverse of the picker will allow; and
through each of the two front corners of the said unturned-up part in each shelf, is
bored a hole so that a bolt may be inserted perpendicularly through the whole
series of shelves at each of the said corners respectively. But to hold the said
shelves firmly and yet at their proper distances apart, we place in each com-
partment two tubes of suitable dimensions; one tube at each of the above named
corners, straight in line with the holes in the said corners, so that the before named
bolts in passing through the series of box shelves, pass through the series of tubes,
the screws or nuts of which, when tightened, bind the whole firmly together.
To keep the weft of each shuttle from being disarranged while the shuttle is in
the shuttle box, we attach to the upper side of the above-named unturned-up
portion of each box shelf, a piece of cloth or other similar rough surfaced material,
so that when the shuttle enters the box the weft falls or is placed upon the said
material which by its roughened surface keeps it in its proper place.
Referring to the sweller mentioned in the second part of our description we make
it with the outer side of its boss or fulcrumed end open or cut away so that by
taking its loose end and turning it outwards, the open side of the sweller's boss is
turned towards the box back and so the said sweller is free to be taken out for
repairs or displacement by a new one, without necessitating the loosening of bolts,
joints etc.; as is usual in an ordinary way, to effect it's liberation. The pin forming
the fulcrum of the said sweller is covered or protected at the part which comes in
contact with it, by a hoop which when worn can be displaced without requiring
the pin itself to be displaced.

Fork, and Treading Motions, and the Construction of Shuttle
Boxes of Looms for Weaving.
We, RICHARD LONGDEN HATTERSLEY of Keighley, Yorkshire, Machine Maker,
and JAMES HILL of the same place, overlooker, do hereby declare the nature of
our invention for IMPROVEMENTS IN THE DRIVING, BRAKE, PICKING, STOP ROD,
WEFT FORK AND TREADING MOTIONS; AND THE CONSTRUCTION OF SHUTTLE BOXES
OF LOOMS FOR WEAVING and in what manner the same is to be performed, to be
particularly described and ascertained in and by the following statement:-
==
;
Our invention consists of an improved arrangement of the several parts forming
the driving, brake, picking, stop rod, weft fork and treading motions or mechanisms
and also of an improvement in the construction of rising shuttle boxes of looms for
weaving; the said invention being explained by the following description, reference
being bad to the sheets of drawings appended.
On sheet 1 is illustrated the driving and brake motions or mechanisms, fig. 1
being end elevation, fig. 2 plan and fig. 3 back elevation thereof. On sheet 2 by
the plan fig. 4, the picking, stop rod and weft fork motions or mechanisms are
shewn; fig. 5 being a sectional elevation on line A, B, of part of fig. 4. On sheet 3
the front sectional elevation fig. 6 shews the picking, stop rod, weft fork and
treading motions or mechanisms; while figs. 7. 8. 9. 10 and 11 are details or
drawings of separate parts enlarged scale. And on sheet 4 the sectional end
elevation fig. 12 further illustrates the picking, stop rod and weft fork motions or
mechanisms while fig. 13 is front elevation of shuttle boxes, fig. 14 a section of
fig. 13 on line a. b. and fig. 15 also a section of fig. 13 on line c. d. Figs. 16, 17
and 18 are drawings of separate parts. In all the drawings only as much of the
loom is shewn as is necessary to illustrate our invention. The part marked C.
indicates the end frame of the loom.
Like letters and figures of reference indicate like parts in all the drawings.
Firstly relating to the arrangement of the driving and brake motions or
mechanisms. Upon the outer end of the top shaft 1 of the loom we mount loosely
so as to revolve and slide, a driving pulley 2, having one of its outer sides formed
to allow a band or facing of leather or other such material 3 to be fixed thereto.
Upon the shaft 1 in close proximity with the pulley 2 is rigidly mounted a circular
metal plate or disc 4, which when turned gives motion to the loom and which has
'each of its sides polished, or otherwise prepared, to form a suitable surface for
contact with the facing 3 of the pulley 2 on one side and the leathered, or other
facing 5 of a brake lever 6 on the other side. The pulley 2 requiring to be pressed
by the weaver into contact with one side of the disc 4, through the medium of
levers 7. 8. 9 and 10 connecting rods 11 and 12, spring 13 (so as to allow of a
*slight yield as occasion may require) and setting on handle 14, when the loom is
required to be driven; and the brake lever 6, being connected by the parts 8. 9. 10.
11 and 12 to the same handle 14, when the motion of the loom is required to be

page_text: arrested, is operated upon simultaneously with the said driving pulley 2, and
presses by the aid of the spring 15, its part 5 against the other side of the disc 4
and so almost instantly arrests the motion of the loom.
When driving with double gear we mount the pulley 2 and friction plate or
disc 4 upon the barrel or elongated boss 16 (fig. 3) of a toothed wheel 17 which
revolves loosely on the top or crank shaft 1 and which is in gear with another
toothed wheel 18 keyed to the low shaft 19, from which part revolving motion is
imparted by the gearing wheels 20 and 21 back again to the said top shaft 1.
Secondly-the arrangement of the picking and stop rod motions or mechanisms.
A tappit 22 commonly known as a picking tappit is keyed upon the low shaft 19;
beneath it and in a suitable position to work in connection with it, is a cone or
picking ball 23, which revolves on a stud 24 rigidly fixed to a horizontal shaft 25
stretching from the back to the front part of the loom; the said shaft 25 being
carried at one end by the swivel joint 26 hinged to the bracket 27 fixed to the end
frame C, at the other end by the arm of a lever 28 which is fulcrumed to a
stand 29 also fixed to the end frame C; the other arm of the lever 28 forms a
segment in which is made a recess into which enters the end of a rod 30, the said
rod 30 being pressed into the recess by the spring 31 which together with the
rod 30 is carried by the stand 29. From this it will be seen that should anything
interfere to prevent the proper working of the picking stick 32 when picking, which
is directly and rigidly during that operation connected by the use of leather
strap 33, lever 34, catch 35 and notched plate 36, to the shaft 25; the extra strain
thereby put on the said shaft 25 will overcome the pressure of the spring 31 (which
is only of sufficient strength to bear the picking of the shuttle in an ordinary way)
and force the rod 30 out of the recess in the segment of the lever 28, thus the
picking ball 23 together with the shaft 25 will yield to the tappit 22 without
picking the shuttle and so prevent any breakages.
The foregoing is a description of the picking motion or mechanism on one side of
the loom only, but to carry or convey motion to the opposite side we mount rigidly
on the shaft 25 a swape or lever 37 to which is hinged a connecting rod 38 which
reaches from the swape 37 to a similar swape 39 rigidly mounted on the shaft 40,
the said shaft 40 being mounted, but to revolve only, in the bearings 41 and 42
fixed to the end frame C, and carrying a notched plate 36a, lever 34a, catch 35a,
and leather strap 33a as connecting parts to the picking stick 32a, in a similar
manner to the shaft 25, but as it is not operated on directly by the picking
tappit 22 it is not necessary to mount it (the shaft 40) in yielding bearings as is
the shaft 25.
Again we might make use of the horizontal yielding shaft 25 with all its fittings
& bearings 26, 27, 28, 29, 30 and 31 on both sides of the loom but in this case we
should require an extra picking ball and tappit similar to 23 and 22.
The working of the picking motion or mechanism above described is controlled
or indicated upon in the following manner:-
Hinged in a suitable position preferably to the back part of the series of shuttle
boxes 43 (43a) is a swell lever or what is commonly called a sweller 44 [(44a) the
formation of which will hereafter be more fully described] one to each compartment
(see fig. 12) each of which is pressed by a suitably shaped spring 45 (45a) so that
its swell part projects into the said compartment.
Fixed to a short horizontal shaft 46 (46a) which is placed directly in a line with
the stop rod 47, is a lever or finger 48 (48a) projecting upwards to come in contact
with the moveable end of the above named sweller 44 (44a) in that compartment
or shuttle box in the series of shuttle boxes 43 (43a) which is level with the
shuttle race (Fig. 12) the said short shaft 46 (46a) being carried loosely at one end
by a stand 49. (49a) fixed to the box-framework 50 (50a), and at the other end
also loosely by the elongated boss of a finger 51 (51a), which is rigidly fixed to the
end of the stop rod 47. Also rigidly fixed to the shaft 46 (46a) is another finger
For lever 52. (52a) which projects downwards and under the box-framework 50. (50a).
The outer end of the said singer 52. (52a) is of inclined shape and is brought into

page_text: contact, by the forward motion of the slayboard, with a projecting piece 53. (53a),
fixed to the end frame C, just at the time when the series of shuttle boxes 43 (43a)
are changing position, and by the action of the inclined end of the lever 52. (52a)
on the projecting piece 53. (53a) the said lever 52. (52a) is. kept from descending
and consequently the finger 48.(48a), being rigidly attached to the same shaft 46 (46a),
is held from contact with the series of swellers 44 (44a) during the time that they
along with their series of compartments of shuttle boxes 43. (43a) are changing
position, thus the said finger 48 (48a) is held from moving backward and forward
and is so prevented from rebounding for a purpose which will hereafter be shewn.
; Attached to the above panied finger 52 (52a) is a small connecting rod 54 (54a)
extending downwards and also attached to a lever 55 (55a) which is rigidly fixed
to the end of a long shaft 56. (56a) carried by the stands 57 and 57a fixed to the
énd frame C. On the other end of the shaft 56 (56a.) is fixed another lever 58 (58a)
which by connecting rod 59 (59a) is coupled to the lever 60. (60a) also carried by
the stand 57a (57). The lever 60. (60a) has one of its ends or arms so formed that
a pin 61. (61a) fixed to the catch 35a (35) overhanging it, shall be operated upon
by it. Here let us mention that as the catch 35a (35) is thus directly operated on
by the sweller 44 (44a), if the finger 48 (48a) was allowed to rebound in passing
from one sweller 44 (44a) to another, as the series of shuttle boxes 43. (43a) were
changing position, this rebounding motion would be imparted to the catch 35a (35)
and so make its connection with the plate 36a (36) very uncertain; from this the
use of the inclined end of the finger 52 (52a) will clearly be seen.
The actions of the foregoing parts are as follows:-Suppose that the slayboard D
is moving to the back centre, that is, that it is approaching the place where the
picking motion should be put into operation for the purpose of throwing the
shuttle 62 across the loom, in this position the inclined end of the finger 52 (52a)
is drawn clear of the projecting piece 53 (53a) so that the finger 48. (18a) is then
allowed to press against the end of the sweller 44 (44c) and should there not be a
shuttle in that compartment (as is the case at 43a), the said sweller 44. (44a) is
allowed to project to its greatest extent into the said compartiment, consequently
by the finger 48 (48a) following it, the finger 52 (52a) is further lowered and by
the connecting rods 54 (54a) and 59 (59a), shaft 56 (56a), levers 55 (55a),
58 (68a) and 60 (60a) the catch 35a (35) is lowered into the notch of the
plate 36a (36) thus the picking stick is connected to the picking motion or
mechanism and a shuttle (should one be present in the shuttle box on the opposite
side of the loom to the one the sweller of which has indicated as being empty, as is
illustrated by fig. 4, 43a on one side while 43 on the other side contains shuttle 62)
is thrown across the loom to fill the said empty compartment, the sweller in which
is pressed out by the said shuttle on its arrival and so, the picking motion or
mechanism is again disengaged by the catch 35a (35) being lifted out of gear with
the notched plate 36a.
Since the above described apparatus is fitted to each side of the loom, the con-
stituant parts of which are indicated by the letter a accompanying the figures of
reference on one side to distinguish them from those on the other, it will be clearly
understood that the picking of the shuttle from either side may be effected when-
ever desired.
The above named catches 35 and 35a are connected by the cords 63 and 63a,
levers 64 and 64a, rod or shaft 65, lever 66 and rod 67 to a handle 68 which is
used to operate on the peg lag cylinder of the dobbie so that when the direction of
motion of the said peg-lag cylinder is reversed by the action of the lever 68 for the
purpose of accomplishing that which is commonly known as "lagging back," the
catches 35 and 35a are held out of gear with the notch plates 36 and 36a, thus
the picking sticks are thrown out of gear during the said process of " lagging
back."
The stop rod 47 is fitted to the back part of the slayboard D in the usual manner,
and stretches from the series of shuttle boxes 43 on one side to the series 43a
on the other, and has rigidly fitted to its ends the fingers 51 and 51a, the said

page_text: fingers 51 and 51a being.formed to overhang the fingers 52 and 52a respectively,
so that whenever either of the fingers 48 or 48a is moved or pressed back by the
sweller 44 or 4 ta, the stop rod 47 is partially revolved. Welded or otherwise rigidly
fitted to the stop rod +7 is a projecting piece 69 which reaches in a forward direction
under the slayboard D and-which is so formed either in itself or by having another
piece 70 rigidly fitted to it, that when it is in its lowest position one part of it (the
part 70) will come in contact with a projecting piece 71 fitted to the connecting
rod 12, and the other part 69 with a buffer piece or frog" 72 and spring 73
carried by a bracket 74 fitted to the end frame C.
"1
From this it will readily be understood that whenever the shuttle boxes or com-
partments which are level with the shuttle race or sherrboard on both sides of the
loom are empty, the projecting piece 69 will be in its lowest position and that as it
is brought forward with the slayboard D the said projecting piece will come in
contact with the frog 72, but as the part 70 will also be in its lowest position it
also will come in contact with the projection 71 and so throw the driving pulley 2
out of gear with the disc 4, in the manner and with the result fully set forth in the
first part of our description, just before the piece 69 strikes the frog 72; thus the
concussion and strain on the working parts incident to the abrupt arrest of their
motion when striking the frog previously to disengaging the driving motion or
mechanism, will be entirely avoided. But should there be a shuttle on either side
of the loom in position to push out either of the fingers 48 or 48a then the pro-
jecting piece 69 and part 70 will be raised clear of the frog 72 and of the
projection 71 and so the loom will continue its motion.
Thirdly. Referring to our arrangement of the weft fork motion or mechanism ;
we use the ordinary weft fork 75 which is placed at or near the middle of the loom,
having an oscillating shaft 76 mounted in bearings 77 to the front part of the
slay board D and extending along it to that part of the loon near the rod 12, and
having at that part its usual other parts 78 and 79. The said weft fork 75 being
raised by the spring 80 (fig. 12) through the medium of the lever 81, rod 82 and
small projection or lever arm on part 78, and allowed to fall by the tappit 83
pressing the lever 81, overcoming the spring 80 and lowering or causing to recede
the rod 82. Then should the weft be absent, the weft fork 75 continuing to descend
in the usual well known manuer the finger 79 connected thereto by the parts 76
and 78 also descends and by the motion of the slayboard D strikes the lever 84,
which by the studs So and 86 operates upon the lever 10 and so throws the driving
motion or mechanism out of gear, thus arresting the motion of the loom before the
slay drives the broken pick of weft into the piece being woven.
Fourthly with reference to the treading, our improved arrangements are in con-
nection with the treading motion or mechanism commonly and well known as
Hattersley's positive dobbie. To each of the baulks or swing bars 87 used in the
said dobbie, we hinge in the usual manner two catches 88 and 88a which are made
or formed so as ouly to be pushed by the knivers 89 and 89a respectively, with
which they work in connection and upon which they incessantly rest by having
their outer ends extended a distance equal to that moved by the knivers 89 and 89a
(see figs. 9 and 10), the said outer ends also pass under the shafts 90 and 90a of the
stopper bars 91 and 91a respectively so that it is not possible for the catches 88
and 88a to get out of gear with the said knivers 89 and 89a.
To each of the above named catches 88 and 8Sa near its hinged end is also
hinged another catch 92 or 92a (see figs. 7 and 8) which is made to be drawn by
the Kniver 89 or 89a over which it also extends, and has formed on its upper
edge a notch or catch which engages with the stopper bar 91 or 91a as the case
may be, when not working or indicated upon by the pattern surface of the pattern
cylinder. The outer ends of the said catches 92 and 92a further extend and pass
through holes or loops 93 and 93a formed in the upright rod or needle 94, and is
of a suitably inclined shape so that the said needle 94 might operate freely on one
catch when the other is drawn clear of it by its kniver 89 or 89a..

page_text: Fulcrumed to the framework E of the dobbie and in a suitable position is a
series of levers 95 (95a) corresponding in number to the series of upright
needles 94, one end of each of the said levers 95 (95a) reaching under the end of
each of the said needles 94, the other end extending over the pattern or peg-lag
cylinder 96.
As will be easily understood, when a peg 97 on the peg-lag cylinder 96 presents
itself or is turned to the top of the said cylinder, any one of the above named
levers 95 (95a) lying in its path of motion will be lifted at one end and lowered at
the other so that the needle 94 with which it is in connection is also lowered, so
also are the ends of the catches 92 and 92a carried by that needle, (the lever 95a
with its needle 94a fig. 6. is shewn in this position and the catch 926 is shewn
drawn forward by its kniver 89a as well as being lowered) but as only one of the
knivers 89 or 89a can possibly be in position to receive and act upon one or the
other of the said catches 92 and 92a (in fig. 6 the kniver 89 is in position
for receiving the catch 92, had the peg 97 been under the lever 95 at the proper
time) the catch thus received is drawn by the said kniver (as catch 92b is shewn
drawn by 89a) and by one or other of the baulks 87 and the levers 98 the heald
is raised; while the other catch 92 or 92a rests inactively with the smooth
uniform part of its bottom edge upon the other kniver which was not in position
to receive and act upon it (the kniver 89a being the one shewn out of position),
until the peg lag cylinder 96 is further turned, then, should another peg 97 present
itself under the same lever as before mentioned, the catch 92 or .92a which was
inactive, on account of its kniver not being in position, but which has now moved
into position, is now received and acted upon by the said kniver and so the heald
is kept up; however if no peg is present when the peg lag cylinder 96 is so turned,
the lever 95 is allowed to lift the said catch 92 or 92a (the other catch being
drawn with its inclined end clear of the loop in the needle) out of position or con-
nection with the kniver into position with the before mentioned stopper. bar 91 or
91a consequently the aforesaid heald is pulled down.
Or to dispense with the series of levers 95 (95a) before described, we use a
pattern card cylinder and paper or other cards instead of peg lags the said paper
cards being made to operate directly upon the bottom ends of the needles 94 in a
manner common and well understood.
In order to bring the healds level with each other, for the purpose of taking up
broken ends of warp etc., we mount a shaft 99 in the framing E in such a
manner and position that when it is turned, by the handle 100 attached to it for
that purpose; a rib 101, also attached to the shaft 99, is brought to press upon the
ends of the series of levers 95 (95a) and so put all the catches 92 and 92a into
contact with the knivers 89 and 89a which by their movement accomplish the
desired object.
A further modification in the arrangement and construction of the said heald
machine or dobbie is to form the draw levers 98 with their outer ends projecting
upwards instead of horizontally as heretofore, by this we are enabled more easily
to couple them, by suitable other parts, to the heald levers. These levers 98,
though herein styled draw levers, in reality push or pull in either direction as
required.
Again the stopper bars 91 and 91a have previously been rigidly fixed to the
frame work E, but we now hinge them so that they will yield when pressed in the
direction of the arrows 102 and 102a and be rigid, by their outer ends coming in
contact with the frame work E, when pressed in the contrary direction thus
preventing any breakages that might have been caused by any of the catches 92
or 92a being caught with their thickest or broadest part between the knivers 89
or 89a and the said stopper bars 91 or 91a respectively.
Fifthly The construction of the rising shuttle boxes. Our improved method is
to form the whole of the shuttle box back part 103 in one piece of metal, with
openings 104 and projections 105 for the insertion and fixing of each box shelf 106
and sweller 44 separately, so that any one can be removed, for repairs etc., without

page_text: disturbing or in any way interfering with the other. And in order to give additional
firmness to the said box shelves 106, we leave as much of the front outer edge of
each box shelf to project outwards unturned up as the traverse of the picker 107
(fig. 4) will allow and through each of the two front corners of the said unturned
up part in each shelf 106, is bored a hole a a so that a bolt 108 or 108a may be
inserted perpendicularly through the whole series of shelves 106 at each of the said
corners respectively.
But to hold the said shelves 106 firmly and yet at their proper distances apart,
we place in each compartment two tubes 109 and 109a of suitable dimensions, one
tube 109 or 109a at each of the above named corners, straight in line with the
holes a a so that the before named bolts 108 and 108a in passing through the series
(of box shelves 106 pass through the series of tubes 109 and 109a, the screws or
nuts of which, when tightened, bind the whole firmly together.
To keep the weft of each shuttle from being disarranged while the shuttle is in
the shuttle box, we attach to the upper side of the above named unturned up
portion of each box, shelf 106, a piece of cloth or other similar rough surfaced
material 110, so that when the shuttle enters the box the weft falls or is placed
upon the said material 110 which by its roughened surface keeps it in its proper place.
Referring to the sweller 44 mentioned in the second part of our description, we
make it with the outer side of its boss b (figs. 17 and 18) .open or cut away so that
by taking its loose end and turning it outwards in direction of arrow c (fig. 15)
the open side of the sweller's, boss b is turned towards the box back 103 and so the
said sweller 44 is free to be taken out for repairs or displacement by a new one,
without necessitating the loosening of bolts joints etc., as is usual in an ordinary
way, to effect its liberation.
To keep the swellers 44 from falling out of their places, if perchance any of the
springs 45 should break, we pass a pin 111 through holes in projections 112 formed
on the box back 103.
The pin 113, upon which the sweller 44 is hinged, is covered or protected; at
that part which comes in contact with each of the said swellers 44, by a hoop 114
which when worn can be replaced without necessitating the replacement of the pin
itself.
