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 this invention to be as follows, that is to say :-
It has for its object the construction and arrangement of the parts forming the
weft-fork and heald-operating mechanisms of looms so that the same shall be more
simple, cheap and effective than heretofore.
Respecting the weft-fork mechanism, this is attained by mounting the weft-fork at
or near the centre or middle part of the slayboard of the loom, a groove being cut
transversely in the said slayboard for the reception of the weft-fork when descending
lower than the surface of the warp as is well understood. The said weft-fork con-
sisting of two or more flattened wires or strips of metal fixed to a boss which is
mounted or hinged on a pin carried by suitable bearings fixed to the front of the
slay board, said boss having formed on its lower edge a hook or catch hereinafter
referred to.
Mounted in said bearings, beneath said boss, is a rod to which is imparted vertically
reciprocating motion by means of any of the well known arrangements used for this
purpose, the upper end of said rod coming in contact with the boss of said fork.
By this it will be seen that as the said rod reciprocates the before named fork will be
raised and lowered, said rising being to allow the passage of the shuttle beneath it,
while its lowering will have the effect hereinafter set forth.
On the outer surface of the reciprocating rod is formed an incline which acts upon
one finger of a three-fingered boss mounted loosely on a pin fixed to the bearings
which are attached to the front of the slayboard as before named, by which action the
said three fingered boss is made to oscillate on its said pin or bearing, so that when
the fork is lowered as above named, the hook on the boss thereof will lay hold of one
of the other fingers (which we will herein style the second finger) should there not
be any weft present, and so hold the three fingered boss that its remaining finger
(which we will herein style the third finger) will come in contact (as the slayboard
D

page_text: moves towards the front of the loom) with a lever arm mounted on a shaft, carried
by the front rail of the loom, which by another lever arm disengages the driving
motion. However should there be weft present the fork is arrested in its descent so
that the hook on its boss cannot lay hold of the second finger of the three-fingered
boss consequently it is free to oscillate, and its third finger descends to pass beneath
the arm on the disengaging shaft before named in this manner allowing the loom to
continue in motion.
Respecting the heald operating mechanism this invention has reference to that well
known as Hattersley's dobby and in accordance with this said invention, the con-
struction and arrangement of its parts are of such a nature that, without increasing
the space occupied edgewise by the jack levers therein employed, more space is
allowed for the pegs of the peg-lag mechanism.
This is attained by making the catches, that are mounted to the baulks or swing
levers which are hinged to the above named jack levers, of a suitably bended shape
(for the purpose hereinafter described), and forming the needles through which these
catches are operated by the said peg-lag mechanism, of strips of metal shaped to span
the said catches so as to form grates for them to work in, also by turning or bending
the bottom ends of these needles or strips of metal a suitable distance to one side thus
forming a greater surface for the said pegs to act upon.
The pattern mechanism consists of the well known peg-lag cylinder to which rising
and falling as well as intermittent rotary motion is imparted, the said cylinder being
arranged to press the pegs of the peg lags, which pass around it, directly against the
ends of said needles without the use of the intermediate levers heretofore employed.
Since the pattern mechanism operates directly on the ends of the needles as above
set forth, the catches with which they work in contact being made in a bended or
cranked form enable two rows of indicating pegs to be placed on one lag, one to
operate on one series of catches while the other operates on the other series of catches
when the former are drawn so that, by their bended forms their needles may be
lifted without operating them (the said catches), in this manner only requiring the
pattern cylinder to be rotated or turned once for every two changes in the movements
of the healds through the jack-levers, although its rising and falling movement is
repeated for every separate movement of the said healds.
6
The foregoing is a description of parts that form what is well known as a non-
positive dobby," that is of operating mechanism that effects only one movement of the
healds, relying on the action of springs or weights for the return movement.
Again by these catches being formed of a bended shape as above described space
is allowed for the operation of an extra reciprocating push bar beneath each series of
catches. These said push bars being made to press the swing-levers back in the
opposite direction to that moved by them when drawn by their said catches, in this
manner obtaining what is well known by those conversant with this class of machinery
as, a "positive motion" of the swing levers, the said motion being imparted to the
healds in a manner common and well understood. But to ensure the effectual
operation of the said catches in connection with this positive motion arrangement,
their outer ends are elongated so that when the pattern cylinder has lowered or moved
from them for the purpose of being rotated, by this elongated part resting on the
draw bar the upper edges of said catches on which is formed another catch, is kept in
contact with its stop bar for purposes well understood.
The jointings of the catches to their swing levers above named, as well as the
jointings of the swing levers to their respective jack levers, are so constructed that
though when moved into certain relative positions they may be detached from each
other, when they are in position for working as above described they may be pushed
or pulled as required without being disunited.
Relative to the jointing of the catch to the swing-levers, this is accomplished by
forming the outer end of said swing lever somewhat of a forked shape, between the
two prongs of which is mounted, in a suitable position, a pin, and joining these two
prongs together in a certain part so that when the catch is brought with its end
which is of a suitably hooked shape, into connection with this pin, the said part that

page_text: joins the prongs together will keep said hook in proper connection when in its working
position. However by moving said catch, when so coupled, so that it is brought
parallel or about parallel with its swing lever it will be free of both the pin and the
joining piece and so may be detached.
✓
Respecting the jointing of the swing lover to the jack lever. The outer end of
said jack lever is made of a suitable thickness and has formed on each side of it a
small projection. The swing lever has formed at or about its centre part a hook
which is split so as to span the end of the said jack lever as well as lay hold of the
projections on each side of it. The said hooked part of the swing lever being for the
purpose of moving (as drawing or raising) the jack lever in one direction while by
the end of said jack lever abutting against the said swing lever (being kept in that
position by the hooks spanning same as above described) the return movement of said
jack lever may be or is (as when the push bars are employed) effected. The said
swing lever is also bent or cranked so that it may, when placed in a suitable position
relative with the jack lever, be made to lay hold thereof, while when moved and
placed in its operating position as when in use in the machine it cannot be detached
therefrom.
In order to diminish the number of pattern cards of the pattern mechanism, when
at great length of plain part is to be woven, as for the body portion of a shawl, table
cover or the like (these requiring a different and more complicated manipulation for
their headings or border portions) the said pattern mechanism being applicable to
the above described heald-operating mechanism, but more commonly used in con-
nection with the heald-operating mechanism well known as Hattersley's positive
lobby which is at present extensively in use, it (the said pattern mechanism) is made
to alternate on two lags, the pegs in which are arranged to produce the desired effect
in the cloth or pieco being woven, until released to move to the other lags for
producing the border as desired.
This is attained by making the nogging wheel, which operates the crown wheel
through which intermittent rotary motion is imparted to the pattern cylinder, engage
with and operate said crown wheel on its upper and lower edges (or on its opposite
edges or sides) alternately, so that the cylinder is moved at one time the distance of
one lag forwards, at the other time the same backwards.
To operate the nogging wheel as above described, an excentric or tappit is mounted
on the shaft of the dobby's driving crank and is coupled, by suitable connecting
rods, levers, shafts &c., to operate on the lever arm which moves the nogging wheel.
And when it is desired to arrest this alternating motion it is only necessary to
disconnect these parts by the displacement of a pin that couples one of the levers to
its connecting rod.
Or again if it is desired to produce a design, in the body of the piece being woven,
of a more complicated kind than what is understood as "plain," such an one for
instance as might require three, four or more healds and consequently peg-lags, by
mounting the before named excentric or tappit on a separate shaft and imparting
rotary motion to it in a corresponding degree slower, such as one revolution for every
two of the other shaft, or one for every three &c., it will be seen that the pattern
cylinder may be made to alternate on three, four or more lags as may be desired.

page_text: 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 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 has for its object the production of more simple, cheap and effective weft-fork
and heald-operating mechanisms of looms for weaving, the same being attained by
the novel construction and arrangements of their parts hereinafter described.
In the following description reference is made by figures and letters, to the
accompanying sheets of drawings, figure 1 in which, is a transverse sectional
elevation of a portion of a loom illustrating the weft-stop imechanism. Fig. 2 is a top
view of fig. 1 with a portion shewn as being cut away so as not to hide parts beneath.
Figs. 3 and 4 are sectional elevations, enlarged scale, of the slayboard or lay shewing
the weft-stop mechanism in different positions hereinafter explained. Fig. 5 is a front
elevation shewing the heald operating mechanism applied to a loom. Figs. 6, 7, 8
and 9 are detail drawings enlarged scale of parts of the heald-operating mechanism
hereinafter referred to. Fig. 10 is a sectional elevation of part of fig. 5. Fig. 11 is
a top view of fig. 10. Fig. 12 is back elevation of a portion of Fig. 10. Fig 13
is a sectional front elevation illustrating the heald-operating mechanism applied
to a loom, for operating said healds "positively," or for lifting as well as depressing
them. Fig. 14 is end elevation shewing method of imparting motion to the heald-
operating mechanism illustrated by fig. 13. Fig. 15 is back elevation of part of
fig. 13. Fig. 16 is a front elevation of heald-operating mechanism shewing parts
thereto added to impart alternating motion to the pattern cylinder. Fig. 17 is back
elevation of fig. 16, while fig. 18 is a side elevation of parts added to a portion of fig. 17.
Respecting the weft-stop mechanism, the object of our invention is attained by
mounting the weft-fork at or near the centre or middle part of the slayboard or lay 1
of the loom, a groove 2 being cut transversely in the said lay 1 for the reception of the
prongs when descending lower than the surface of the warp as is well understood
and as illustrated by fig. 4. The said weft-fork consisting of two (or more if
desired) flattened wires or strips of metal 3 fixed to a boss 4 which is mounted or
hinged on a pin 5 carried by bearing 6 fixed to the front of the lay 1, said boss 4
having formed on its lower edge, a hook or catch a hereinafter referred to.
Mounted in bearings 6, beneath the boss 4, is a rod 7 to which is imparted vertically
reciprocatory motion by means of any of the well known arrangements used for this
purpose (the arrangements employed as herein shewn being the rod 8 mounted by the
pin 9 to the bearings 10 which by the difference in the positions of the centres of
motion of said rod 8 and the lay sword 11, the vertically reciprocatory motion of the
rod 7 is obtained), the upper end of said rod 7 coming in contact with the boss 4.

page_text: By this it will be seen that as the said rod 7 reciprocates the prongs 3 will be raised
and lowered, said rising being to allow the passage of the shuttle beneath it, while its
lowering will have the effect hereinafter set forth.
On the outer surface of the rod 7 is formed an incline which acts upon the finger b of
the three-fingered boss 12 which is pivoted on a pin 13 fixed to the bearings 6, by
which action the said boss 12 is made to oscillate on its said pin 13 so that when the
prongs 3 together with the boss 4 are lowered as above described, the hook a on the
boss 4 will lay hold of the finger b₁ of the boss 12 should there not ho any weft
present (as shown by fig. 4), and so hold the said boss 12 that its remaining finger b²
will come in contact (as the lay 1 moves towards the front of the loom) with a lever
arm 14 (see fig. 4) attached to the shaft 15, which, by the arm 16 operating lever 17
to which are attached the pins 18 and 19 that operate the stopper-lever 20, arrests the
motion of the loom, by disengaging the driving mechanism in a manner common and
well understood. However should there be a shot of weft present as shewn at c fig. 3,
the prongs 3 together with the boss 4 are arrested in their descent so that the hook a
on the said boss 4 cannot lay hold of the finger 6' consequently the boss 12 is free to
oscillate and so its finger 2 descends to pass beneath the arm 14, in this manner
allowing the loom to continue in motion.
Respecting the heald-operating mechanism, this invention has reference to that well
known as Hattersley's dobby, and in accordance with this said invention, the con-
struction and arrangement of the parts employed are of such a nature that, without
increasing the space occupied edgewise by the jack levers therein employed, more
space is allowed for the pegs of the peg-lag mechanism.
This is attained by making the catches 21, 22 (see fig. 9), which are pivoted to the
swing levers 23, (said levers 23 being hinged or pivoted on the jack levers 24,) of a
suitably bended shape (for the purpose hereinafter described), and forming the
needles 25 through which the said catches 21, 22 are operated by the herein before
named peg-lag mechanism, of strips of metal shaped to span said catches so as to
form grates or grids for them to work in (see fig. 11A), also by turning or bending
the bottom ends of these needles 25 a suitable distance to one side thus forming a
greater surface for the pegs d of the peg-lag mechanism to act upon.
The pattern mechanism consists of the well known peg-lag cylinder 26 to which
rising and falling motion, by the eccentric 27 mounted on the top or crank shaft 28
of the loom, the rod 29 in connection with said eccentric and the levers 30 and 30 a
fixed on shaft 31, said shaft being loosely carried by the frame work B and said
levers 30 and 30 a carrying the said cylinder 26, is imparted. To the said cylinder 26
is also imparted intermittent rotary motion by the ratchet wheel 32 fixed on shaft of
cylinder 26 being operated with the ratchet 32a pivoted on the lever 33, joined by
rod 34 to lever 35 pivoted on the lever 36 (said lever 35 being held against the
lever 36 as shown by fig. 5 with the spring 37 which arrangement is to prevent any
breakages by said spring yielding should the cylinder 26 be hindered from being
turned or revolved by the lags wrapping same or any other cause), the said lever 36
having oscillatory motion imparted to it by being mounted rigidly on the shaft 38 to
which is attached the lever 39 (said shaft 38 being mounted loosely in framing B),
which is coupled to the swape 40 by the rod 41, said swape 40 being rigidly fixed to the
bottom or low shaft 42 of the loom, as will be well understood.
The pattern cylinder 26 being arranged to press the pegs d of the peg-lags e (see
fig. 10) directly against the ends of the needles 25 without the use of the intermediate
levers heretofore employed, and the catches 21 and 22 with which they work in
contact being made in a bended or cranked form (as illustrated by fig. 9), enable two
rows of indicating pegs to be placed on each lag e, one to operate one series of
catches while the other operates the other series of catches when the former are drawn
so that, by their bended or cranked forms their needles may be lifted without operating
them (the said catches 21, 22) in this manner only requiring the pattern cylinder 26
to be rotated or turned once for every two changes in the movements of the healds 43
through the jack-levers 24, although its rising and falling movement is repeated for
every separate movement of said healds 43.

page_text: To adjust the cylinder 26 after each rotating movement above described, the usual
star-wheel a with the piece y and the spring z are employed, the same being common
and well understood.
The foregoing is a description of the parts that form what is well known as a non-
positive dobby," that is of operating mechanism which effects only one movement of
the healds, relying on the action of springs or weights for the return movement.
Fig. 5 shews this mechanism arranged for raising the healds, while the springs 44 are
for depressing same.
Again by the catches 21, 22 being of a bended or cranked shape as above described
space is allowed for the operation of an extra reciprocating push bar 45, 45 a
beneath each series of catches. These said push bars 45 and 45 a (which obtain
their motion by being coupled with the rods 47, 47 a to the draw-bars 46, 46 a)
being made to push the levers 23 back in the opposite direction to that moved by them
when drawn by their said catches 21, 22. The catches 21, 22 are operated or drawn
by the draw-bars 46 and 46 a which are operated by the levers 38 and 39 the same
obtaining their motion from the crank 59 through the rod 41; said crank 59 being
driven by the wheels 59 a and 59 6 from the loom's crank 28 as herein before described;
in this manner imparting motion in both directions, the same being well known to
those conversant with this class of machinery as a "positive motion to the levers 23
and consequently to the healds 43 by means of the levers 49, 49 a, 50, 50 a connecting
rods 51, 52, 53 and 54, and the jack-levers 24 to which said levers 23 are pivoted as
will be seen. But to ensure the effectual operation of the catches 21 and 22 in
connection with this positive motion arrangement, their outward ends mm² are
elongated so that when the pattern cylinder 26 has lowered or moved from supporting
them by their needles 25, for the purpose of being rotated, by this elongated part m
or m² resting on the draw-bars 46 or 46 a, the upper edge of said catches 21 and 22 on
which is formed another catch n n' is kept in contact with its stop har 55 or 55 a for
purposes well known.
i
The jointings of the catches 21, 22 to their swing levers 23 hereinbefore named, as
well as the jointings of the said swing levers to their respective jack levers 24 are so
constructed that though when moved into certain relative positions they may be
detached from each other, yet when they are in position for working as above described
they may be pushed or pulled as required without being disunited.
Relative to the jointing of the catch 21 or 22 to its lever 23, this is accomplished by
forming the outer end of said lever 23 somewhat of a forked shape, between the two
prongs of which is mounted, in a suitable position, a pin g; and joining these
two prongs together in the part (see fig. 9) so that when the catch 21 or 22 is
brought with its end which is of a suitably hooked shape, into connection with the
ping; the said part that joins the prongs together will keep said hook in proper
connection when in its working position. However by moving said catch 21 or 22,
when so coupled, so that it is brought parallel or about parallel with its lever 23 as
shewn in broken lines fig. 9, it will be free of both the pin g and the joining piece h
and so may be detached.
Respecting the jointing of the lever 23 to the jack lever 24, the outer end of said
jack lever 24 is made of a suitable thickness and has formed on each side of it a small
projection see fig. 8. The swing lever 23 has formed at or about its centre part,
a hook which is split so as to span the end of said jack-lever 24 as well as lay hold
of the projections & on each side of it. The said hooked part of the swing lever 23
being for the purpose of moving (as drawing or raising) the jack-lever 24 in one
direction while by the end of said jack-lever 24 abutting against the said swing
lever 23 (being kept in that position by the hooks spanning same as above described)
the return movement of said jack-lever 24 may be or is (as when the push bars 45, 45 a
are employed) effected. The said swing lever 23 is also bent or cranked so that it may,
when placed in a suitable position relative with the jack-lever 24 as shewn in broken
lines fig. 6, be made to lay hold thereof, while when moved and placed in its operating
position as when in use in the machine and as shewn by full lines fig. 6 it (the said
fever 23) cannot be detached therefrom.

page_text: This invention further extends to the application of means to the pattern mechanism
of the hereinbefore described heald-operating mechanism whereby the number of peg-
lags is greatly diminished when the production of shawls, table-covers or the like, is
desired (these articles requiring a different and more complicated operation of their
warps for their headings or border portions than is required for their central portions)
or those improved means may be applied with equal advantage to the heald operating
mechanism well known as Hattersley's positive dobby, and it is in connection with the
latter that we hereinafter described it, from which it will readily be understood, how
same may be applied to the former as is hereinafter shewn.
This object is attained by making said mechanism alternate on two, or if desired
more, of its lags, that is, making it to put the heald-operating mechanism into and out
of effectual operation as the case may be, by the pattern surface of two or more of its
lags being alternately brought into use for the purpose of producing the middle or
centre portion of the pattern by the pegs in said lags being arranged to produce the
desired effect in the cloth or piece being woven; until released to move to the other
set of lags for producing the border as desired.
We accomplish this by making the nogging wheel 56, which operates the crown
wheel 57 through which intermittent rotary motion is imparted to the pattern
cylinder 26, engage with and operate said crown wheel on its upper and lower edges
alternately, so that the cylinder 26 is thereby moved at one time the distance of one,
two or more lags in one direction, at the other time the same distance in the other
direction.
To operate the nogging wheel 56 as above described, an eccentric or tappit 58 is
mounted on the shaft of the dobbie's driving-crank 59 from which motion is imparted
to said nogging-wheel 56 by the rod 60 joined to the lever 61 mounted on the shaft. 62
which is carried by the framework D, upon said shaft 62 being rigidly mounted the
lever 63 which is attached or hinged by the pin 64 to the rod 65 (said pin 64 being
loosely screwed in for the purpose of being easily removed as hereinafter explained),
said rod 65 being joined to the lever 66 which is mounted on the shaft 67 to which is
attached the lever 68 which raises and lowers the nogging wheel 56 as desired. And
when it is desired to arrest this alternating motion it is only necessary to disconnect
these parts by the displacement of the pin 64 which thus allows the lever 63 to move
backwards and forwards without moving the rod 65.
When the eccentric or tappit 58 is mounted upon the shaft of the dobby's crank 59 as
above described it will be seen that the cylinder 26 will alternate on two lags only, as
the said crank runs at that rate of speed, so that the part in the cloth woven as indi-
cated by those two lags will be what is understood as "plain." However should it be
desired to produce a different design for this portion of the article being woven, such
as one requiring three, four or more lags, then the eccentric 58 is placed on another
shaft 69 which is driven in a corresponding degree slower by the gearing wheels 70
and 71 (see fig. 18, the gear 70 being also shown in dotted lines in fig. 17) as will be
well understood, thus keeping the nogging wheel 56 in its raised as well as in its
lowered positions as long as is desired for it to accomplish the proper number of
changes in the crown wheel 57.
In order to enable the above described arrangement to be applied to the heald
operating mechanism hereinbefore described, and as illustrated by fig. 5, it is only
necessary to dipense with the eccentric 27, rods 28 and 34, lever 35, ratchet 32 a and
wheel 32, and in place of these to use the nogging wheel 56, crown wheel 57, means
for operating these, and the means employed for imparting the vertically oscillatory
motion to the cylinder 26, as illustrated by fig. 19 (which is the back elevation of a
portion of a machine similar to the one illustrated by fig. 5), said means being more
fully described in the specification of patent granted to us July 4th 1885-No. 8109.
Having now particularly described and ascertained the nature of our said
invention, and in what manner the same is to be performed, we declare that what
we claim is —
1. The combination, in weft fork mechanisms, of the boss 4 having a hook
a,
the
