Take-up Mechanisms of Looms for Weaving.
We, RICHARD LONGDEN HATTERSLEY of Keighley in the County of York, Machine
Maker, and JAMES HILL of the same place, Mechanic, do hereby declare the nature
of this invention to be as follows:-
That is to say it consists of improvements in the treading, picking, let-off and
take-up mechanisms of looms for weaving, by the employment of which the efficiency
of said looms is greatly enhanced.
Our invention relates firstly to that class of treading mechanism, used in looms for
weaving, usually styled the positive tread-tappit or box-tappit mechanism, and
consists of a modification in the arrangement of the undergearing so that the long
levers heretofore employed beneath the healds as is well understood, are dispensed
with, the parts used in place of same not being of so fragile a nature.
This we attain by mounting on suitable bearings beneath the loose ends of the levers or
treadles operating in connection with the box tappits, an appropriate number of
grooved bowls or pulleys, and over these grooved bowls are made to pass coupling
chains one end of each of which is joined by suitable intervening parts to the outer
or loose end of each of the treadles above described, their other ends extending beneath
the loom so as to be coupled to suitable quadrant shaped levers, which by other chains
and the usual well known parts are coupled to the lower edges of the healds as will
be well understood. Instead of the chains extending the whole distance beneath the
loom as above described, a suitable portion of their middle parts may be replaced by
suitable connecting rods.
The series of quadrant-shaped levers above described are made so that a certain
portion of their segment parts increases progressively in length from the one at the
back to the one at the front part of the loom in order to allow that variation in
movement desired in connection with the healds as is well understood.
The grooved bowls above described are arranged in two series, one above the other,
and they are also placed in suitable relative positions so that the chains passing around
same may extend, without coming into contact with each other, to their respective
quadrant levers beneath the loom.

page_text: Secondly our invention relates to the application of means to, and the arrangement
of parts in connection with looms wherein several rising and falling or drop boxes are
employed, whereby we are enabled to utilize the machine, well known as the
double-lift Jacguard machine, in connection with said loom without incurring the
liability of said machine and said loom being disarranged one with the other as the
well known operation of lagging back is being performed.
This we attain by utilizing such parts of the machine, well known as Hattersley's
positive dobby, in connection with said loom, as are sufficient to control or govern the
operations of the picking mechanism, these parts of said dobby being fully
described in specification of patent granted to us July 4, 1885, No. 8109, about
double the number of parts similar to those referred to, being used to control or govern
and operate the rising and falling shuttle boxes, by being joined with suitable rod and
lever connections to any of the well known box operating mechanisms at present in
use, said method of operating the boxes by the dobby being well understood.
We also make use of the driving crank which imparts motion to the dobby above
described, however we in this case make this crank to have two sweeps or "throws,"
one sweep is used in the usual way to drive the dobby having at its jointing to the
dobby's driving lever, a suitable hinged or swivelled joint so that one of the
connecting rods which operates one of the lifting levers in the Jacquard machine may
be joined thereto for said purpose of imparting motion to this said lifting lever; while
the other sweep in the crank is for imparting motion in a similar way by another
connecting rod joining same to the other lifting lever in the Jacguard, an intermediate
lever being mounted in a suitable position to the frame work of the loom to intercept
the connection of the last named sweep to the lifting lever in a similar manner to the
interception by the dobby's driving lever of the other rod, by which means the
operations of these rods, without vibrations, is properly secured.
From the horizontal rod which is used in connection with the dobby, hereinbefore
referred to for the purpose of reversing the direction of motion of the pattern
mechanism in connection with said dobby as well as for disengaging the picking
mechanism for the purpose of lagging back; motion is imparted by suitable lever and
rod connections, to the catches which operate the pattern mechanism of the Jacquard,
whenever said rod is moved to effect the changes in the dobby, so that by these
means when said rod is moved to throw the picking mechanism out of gear, as well as
to reverse the direction of motion of the dobby's pattern mechanism, the pattern
mechanism of the jacquard machine will be reversed, and when said rod is moved to
place these said parts in connection with the dobby into position or order for proper
operation then the jacguard's pattern mechanism will be placed in the same order so
that the one portion of mechanism does not become disarranged with the other.
The arrangement above described enables us to utilize a portion of the levers in the
dobby for operating a certain portion of the warp with healds whenever desired
though the other portion of said warp is or may be operated by the Jacguard machine.
Or again should it be desired to operate all the warp by the dobby mechanism, it is
only necessary to tie up or lift the harness of the Jacguard machine high enough to
allow the top levers for operating the healds to be placed on their usual supports, no
fittings, bearings or other parts, except the cumber-board, in connection with the
Jacquard machine being required to be removed.
t
When it is thought desirable to utilize a Jacguard machine as well as a "dobby" in
connection with a loom having several rising and fulling shuttle boxes, and yet allow said
Jacguard machine and said dobby to operate separately or independently one of the other
but each in connection with the loom, we utilize the following means for disengaging the
picking mechanism, so that by the cessation of the operation of picking we may move
the shuttle boxes or other parts of the loom and treading motions without losing the
proper positions for the shuttles in their respective boxes.
The means for disengaging the picking mechanism consists of placing or mounting,
about the middle part of the connecting rod which imparts reciprocatory motion to the
picking tappits of the loom (said rod being common and well known), a suitable
slotted joining piece which lays loosely hold of each of the parts forming this said

page_text: connecting rod, spiral or other springs being attached to same in as much as to canse
the ends of said parts to meet within this slotted joining piece unless prevented by
the insertion of a suitable wedge shaped block within the slot of said joining piece.
When this block is inserted within the slot as above described, the ends of the parts
forming the connecting rod are pressed outwardly by which means the picking tappits
are in proper position for being placed into operation; however when this block is
withdrawn then the parts forming the connecting rod are drawn by their respective
springs with their outer ends together and so the picking tappils are out of position
for being put into effectual operation.
The movements of the block above described may be effected by a foot treadle or
other suitable motion, easily operated by the weaver.
Thirdly our invention relates to improvements in the construction of certain parts
used in connection with the treading mechanism known as Hattersley's non-positive
dobby, and consists of forming same so that their cost of production is diminished
without any deterioration of their durability.
This is attained by forming the needles or lifting bars which operate the catches in
these dobbys somewhat of the shape described in the specification of patent granted
to us Feby. 9th 1887 No. 2018 but arranging same to operate within suitable grids or
grates having two rows of holes or openings for same to operate within; in such a
manner that the needles in one row are opposite the blanks in the other row so that
these needles are allowed more room in which to operate without increasing the
lateral distance between the catches they operate, by these means we are enabled of
construct these needles of a more substantial form as in cast iron etc., in contra-
distinction to the method of construction described in connection with the specification
No. 2018 above referred to.
The grids or grates we also construct of cast iron, and we leave openings in the
framework of the machine for the insertion of these grids so that they may be
attached by suitable brackets to said framework, and yet be detachable whenever
desired.
Instead of the intermediate levers that are operated by the pattern mechanism for
the purpose of operating the needles, being securely (though loosely) mounted upon
their shaft as heretofore they are made to lay hold loosely thereof so that each one
may be detachable without interference with the other.
In order that a proper and substantial jointing may be formed on each of the outer
ends of the knivers or draw bars in these machines, openings are made in the end
frames so that these knivers with their strengthened jointings may be inserted.
The peg.
lags in connection with the above machines, or in connection with any
such machine are constructed according to this invention, by forming a suitable dove-
tailed groove in each of them.
This dovetailed groove is formed on the upper surface of the lag and each of the
pegs used in connection with these lags has a suitable groove or hollow formed around
it at a proper distance from its lower end so that when it is driven into the lag a piece
of wire may be slided or passed along the groove in the lag beneath the flange on the
edge or side of said groove, and through the hollow in the peg by which means said
pegs are retained or locked in connection with the lag.
When the lags have two rows of holes for the reception of pegs a broader devetailed
groove may be formed in them so that a wire may be passed up each side as above
described, or in this case one wire may be used and bent C shaped as will be well
understood.
By forming a shoulder or collar around each of the pegs (used in connection with
the lags) at a suitable distance from their lower ends, and on the part beneath this
shoulder forming two spiral or helical grooves or projections to partly pass around
said part so as to leave about as much of it uncovered by them as they cover, the
dovetailed groove and wire above described may be dispensed with; since when these
said pegs are driven into the lags and twisted or rotated balf a turn around, these
helical grooves or projections will lay hold of said lag and the pegs will be thereby
held.

page_text: Fourthly our invention relates to improvements in the take up mechanisms of looms
of that class well known as the "balance take up," and consists of arranging same so
that suitable toothed wheels may be made detachable in order that they may be
exchanged for similar wheels having a greater or less (as may be desired) number of
teeth, so that the rate of speed of the cloth roller or piece-beam may be varied to suit
the varied thickness or weights of cloth that are to be woven.
This is attained by mounting the catch wheel in suitable bearings attached to the
end frame of the loom, and arranging the toothed wheel though rigidly attached so as
to revolve with said catch wheel, as well as the toothed wheel in which same gears, to
be detachable.
The catches or pawls in connection with the catch wheel above referred to, and
which are known as the draw and holding catches are arranged, the one by having a
suitable opening and the other a suitable projection formed therein and thereon, the
one to receive the other within it, so that they may with a greater degree of certainty
engage with and operate said catch wheel, as well as be more easily manipulated by
the weaver.
Fifthly our invention relates to improvements in the let-off mechanisms of looms of
the class known as worm-and-wheel let-off.
As is well known the warp is unwound or let-off from the warp beam in connection
with this worm-and-wheel mechanism, according to the extent of its pressure upon the
back rail or hinged back bearer, and the object of our invention is to make said
mechanism respond to the least variation of said pressure, so that though said back
rail may only be moved very slightly yet the releasing catch, which operates the
worm-and-wheel for letting off the warp, shall have considerable motion imparted
to it.
This we attain by mounting an additional lever or levers to operate between the
levers in which the back rail is mounted and those that are connected with the
operating catch which imparts motion to the worm and wheel. The lever or levers so
added, are joined or coupled to the other levers by suitable means and in such a
manner that the desired purchase is obtained as will be well understood.

Take-up Mechanisms of Looms for Weaving.
We, RICHARD LONGDEN HATTERSLEY of Keighley in the County of York, Machine
Maker and JAMES HILL 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 consists of improvements in the treading, picking, drop-box,
let-off and take-up mechanisms of looms for weaving of such a nature that by the
employment thereof the efficiency of said looms is greatly enhanced.
In the following description reference is made to the accompanying sheets of

Figs. 26 and 27 are end and sectional front elevations of a portion of a loom
shewing the take-up mechanism applied thereto. Fig. 28 is a similar view to fig. 26
but illustrates another arrangement of some of the parts.
Figs. 29 and 30 are respectively sectional end and top views of a portion of a loom
with our improved portion of the let-off mechanism applied thereto.
Similar letters and figures refer to similar parts throughont the several views.
In all the drawings only such portions of a loom are shewn as are necessary to
illustrate our invention.
Our invention relates, firstly, to the application of means to, and the arrangement
of parts in connection with looms wherein several rising and falling or drop-boxes are
employed whereby we are enabled to utilize the machine, well known as the double-
lift Jacquard machine in connection with said loom without incurring the liability of
said machine and said loom being disarranged one with the other as the well known
operation of "lagging-back" is being performed.

page_text: This we attain by utilizing such parts of the machine well known as Hattersley's
positive dobby, in connection with said loom, as!are sufficient to control or govern the
operations of the picking mechanism, these parts of said dobby being fully described
in specification of patent granted to us July 4th 1885 No. 8109, the same being partly
illustrated by fig. 6, about double (or if rising and falling boxes are on both sides
of the loom then four times) the number of parts similar to those referred to (said
double number of parts consisting of two of the levers c, means for actuating same
which are common and well known, two of the levers d, rods e e, levers fand rods
as illustrated by fig. 6), being used to control or govern and operate the rising and
falling shuttle boxes by (the rods g) being joined to any of the well known box-
operating mechanisms at present in use as will be readily understood.
We also make use of the driving crank which imparts motion to the dobby above
described, however we in this case make this crank to have two sweeps 12 and 12 a,
one sweep 12 being used in the usual way to drive or impart motion to the dobby's
operating lever arm 13 and having at its jointing a suitably hinged or swivelled
joint so that the rod 14 through which motion is imparted to the lifting lever 15 may
be joined thereto for the purpose of operating said lifting lever 15; while the other
sweep 12 a in said crank is for imparting motion to the lifting lever 15 a by being
coupled thereto with the rod 14 a, if desired an intermediate lever similar in form and
arrangement to the lever arm 13 may be employed as shewn in broken lines fig. 4 by
which means said rods 14 and 14 a are rendered more rigid and better prepared for
performing their functions.
"
From the horizontal rod 16 which is used in connection with the above described
dobby for the purpose of reversing the direction of motion of said dobby's pattern
mechanism as well as for disengaging the picking mechanism for the purpose of
lagging back"; motion is imparted through the medium of the lever 17 which
is pivoted at 18 to the framework of the loom and which has a suitably shaped slot
formed in it to allow the operations of the pin 19 which is attached to said rod 16,
said pin 19 being moved horizontally as is the rod 16, causing the lever 17 to oscillate
about its centre and to move the rod 20 which is coupled by the spring 21 to the
catch 22 which is further joined to the catch 23 by a piece of string or wire in the
usual well known manner. The spring 21 is employed for the purpose of yielding as
occasion may require such as when the catch 22 has laid bold of the pattern cylinder 24
by which means the movement of the rod 16 may be effected though that of the
catch 22 may not be simultaneously effected but be so acted upon that as soon as
released it will move.
By the above described rod 16 together with its other parts for changing the
direction of motion of the dobby's pattern mechanism, being employed for the
purpose of effecting a similar change in the pattern mechanism of the Jacquard
machine, these said pattern mechanisms are prevented from being disarranged one
with the other, or in other words when the rod 16 is moved to throw the picking
mechanism out of gear, as well as to reverse the direction of motion of the dobby's
pattern mechanism, the pattern mechanisms of the Jacquard machine will be reversed
and when said rod 16 is moved to place these said parts in connection with the dobby
into position or order for proper action then the Jacquard's pattern mechanism will be
placed in the same order.
The arrangement above described for coupling the two indicating mechanisms of
the Jacquard and dobby respectively together, enables us to utilize a portion of the
levers in the dobby for operating a certain portion of the warp with healds as shewn
in broken lines fig. 4, whenever desired though the other portion of said warp is or
may be operated by the Jacquard machine. Or again should it be desired to operate
all the warp by the dobby mechanism it is only necessary to tie up or lift and hold
the harness of the Jacquard machine high enough to allow the desired quantity of the
top levers (shewn in broken lines fig. 4) for operating the healds to be placed on their
usual supports, no fittings, bearings or other parts, except the cumber-board, in
connection with the Jacquard machine, being required to be removed.
When it is thought desirable to utilize a Jacquard machine as well as a dobby in

page_text: connection with a loom having several rising and falling shuttle-boxes, and yet allow
said Jacquard machine and said dobby to operate separately and independently one of
the other but each in connection with the loom, we utilize the following means for
disengaging the picking mechanism, so that by the cessation of the operation of
picking we may move the shuttle boxes or other parts of the loom and treading
motions without losing the proper positions for the shuttlos in their respective
boxes.
The means for disengaging the picking-mechanism consist of placing or mounting,
about the middle part ot the connecting-rod 25 25 a which imparts the reciprocatory
motion to the picking tappits 26 and 26 a in the well known manner, a suitably slotted
joining piece 27 which is made to lay loosely hold of each of the parts 25, 25 a, see
figs. 6, 7, 8 and 9. To the parts 25, 25 a are attached the springs 28, 28 a in such
a manner as to cause the ends of said parts 25, 25 a to meet within the piece 27
unless they are prevented by the insertion of a wedge-shaped block 29 within the slot
of said piece 27.
When this block 29 is inserted within the slot of the piece 27 as above described,
the ends of the parts 25, 25 a are pressed outwardly by which means the picking
tappits 26 and 26 a are placed in proper relative positions for being put into operation,
however when this block 29 is withdrawn then the parts 25, 25 a are drawn by their
respective springs 28, 28 a so that their outer ends shall approach each other by which
means the picking tappits 26, 26 a are drawn out of position for being put into
effectual operation.
The movements of the block 29 may be effected by a pedal 30 (said pedal being
retracted by the spring 31) which is pivoted at 32 and attached to the block 29
by the rod 33 as and whenever desired, or other means than this pedal 30 may be
employed as will be readily understood.
Secondly our invention relates to improvements in the construction of certain parts
used in connection with the treading mechanism known as Hattersley's non-positive
dobby, and consists of forming said parts so that their cost of production is diminished
without any deterioration of their durability.
This we attain by forming the needles 35, which operate the catches 34 used in
the dobbies above described, somewhat of the shape described in the specification
of patent granted to us Feby. 9th 1887 No. 2018, and as shewn by fig. 16 which is
side and edge view thereof, but arranging said needles 35 to operate within suitable
grids or grates 36 (see detail drawing fig. 17) which have two rows of holes or
openings 36 a and 306 for same to operate within, in such a manner that the needles
in one row, say 36 a are opposite the blank parts in the other row or 366 so that each
of these needles is allowed more room laterally in which to operate without increasing
the length of the grid 36 or the lateral distance between the catches 34 which they
operate, by these means we are enabled to construct these needles 35 of a more
substantial form, as in cast iron etc., in contradistinction to the method of
construction described in the specification No. 2018 hereinbefore referred to.
The grids 36 are also constructed of cast iron, and openings are made in the
framework 37 of the machine for the insertion of these grids 36 so that they may be
attached by the brackets 38 to said framework 37 and be detachable whenever
desired.
Instead of the intermediate levers 39, which are operated by the pattern
mechanism 40 for the purpose of operating the needles 35, being securely (though
loosely) mounted upon their shaft 41 as heretofore, they are made to lay hold loosely
thereof by means of being formed with a notch 39 a (fig. 18) so that each one may
be detachable without interference with the other. By these levers 39 having the
notches 39 a formed in them we are enabled to raise or lift them with the pronged piece 42
(see fig. 15) as shewn in broken lines fig. 12 so that when a peg 40 a of the pattern
mechanism 40 has operated or moved any one of said levers 39 in order to put
its catch 34 into connection with the draw bar 43 or 44; by moving the handle 45 to
effect said additional upward movement of the lever 39 with the pronged-piece 42,
said catch 34 is again lifted out of connection with its draw-bar 43 or 44 by which

page_text: means the heald to which said catch is joined or coupled for the purpose of effecting
its operation, may be pressed down into the same plane as those of said healds that
were not thus lifted, again it will be seen that any other of said levers that are raised
by their respective pattern pegs and that may be in the path of movement of any one
of the prongs of said pronged-piece 42 will in like manner be lifted, in this manner
permitting the well known object of levelling the healds to be accomplished.
In order that a proper jointing may be formed on each of the ends of the knivers or
draw-bars 43 and 44 suitably shaped openings 37 a are formed in the framework 37
so that said draw-bars 43 and 44 with their strengthened jointings may be inserted so
as to operate in the well known manner within the slots made in said framework 37.
The peg-lags 46 to be used in connection with the above named machines, or with
any such machine are constructed according to this invention, by forming a suitable
groove in each of them. This groove is formed near the upper surface of the lag 46
and each of the pegs 40 a to be used in connection therewith has a suitable groove or
hollow 406 formed around it at a proper distance from its lower end so that when it
is driven into the lag 46 as shewn by fig. 19, a piece of wire 47 may be slided or
passed along the groove in said lag 46 and through the hollow 406 on one side of
said pog 40a by which means said peg 40 a (or all the row of said pogs 40a as shewn
by fig. 20) is (or are) retained or locked in connection with the lag 46.
When the lags 46 have two rows of holes as shewn by fig. 23, a broader groove is
formed in them so that a piece of wire 47 a 47 b may be passed up each side of said
pegs 40 a as above described as shewn by fig. 22, or in this case one piece of wire 47 c
may be employed by being bent as shown by fig. 23.
By forming a shoulder or collar 47 d around each peg 40 a at any suitable part
along its length, provided that the distance between said collar 47 d and the lower
end of said peg 40 a corresponds with the thickness of the lag in connection with
which it is desired to be used, and on the part beneath said shoulder 47 d forming one,
two or more spiral or helical grooves or projections (each of said grooves or projections
being made to extend only about half way around the part of the peg upon which it
is formed) 47 e, the groove in the lag as above described and the wires 47 a, 47 b
or 47 c may be dispensed with, since when these said pegs 40 a with the shoulders 47 d
and projections 47 e are driven into the lags 46 and are then twisted or rotated half a
turn around, the grooves or projections 47 e will lay hold of said lag 46 and by these
means the pegs 40 a will be securely attached thereto.
Thirdly our invention relates to improvements in the take-up mechanisms of looms
of that class well known as the "balance take-up," and consists of arranging same so
that suitable toothed wheels may be made detachable in order that they may be
exchanged for similar wheels having a greater or less (as may be desired) number of
teeth, so that the rate of speed of the cloth roller or pièce beam may be varied to suit
the varied thicknesses or weights of cloth that are to be woven.
This is attained by mounting the catch wheel 48 in suitable bearings attached to the
end frame of the loom and arranging the toothed wheel 19 to be detachable from
the wheel 48 though it may be securely attached thereto for the purpose of being
rotated therewith, as by said wheel 49 being mounted upon the boss 48 a formed on
the wheel 48 as shewn by sectional view fig. 28 a, and a projection attached to said
boss 48 entering a recess in the boss of the wheel 49 or said attachment may be
accomplished in any other suitable manner. The toothed wheel 50 which gears with
the wheel 49 is also made detachable from the piece beam's shaft 51 in this manner the
wheels 49 and 59 may be substituted by the wheels 49 a and 50 a as shewn by
fig. 28.
By the draw-catch 52 having the opening 52 a formed in it, and the holding catch 53
having the projection 53 a formed thereon, said projection 53 a being arranged to enter
the opening 52 a both said catches are made to inore certainly engage with and operate
said catch-wheel 48, as well as being rendered more easy to manipulate by the
operative.
Fourthly our invention relates to improvements in the let-off mechanisms of looms
of the class known as the worm-and-wheel let-off.

page_text: As is well known the warp is unwound or let-off from the warp beam in connec-
tion with this worm-and-wheel mechanism, according to the extent of its (said warp's)
pressure upon the back rail 54 or hinged back bearer 54a, and the object of our
invention is to make said mechanism respond to the least variation of said pressure so
that though said back rail may only be moved very slightly yet the releasing catch,
which operates the worm and wheel for letting off the warp, shall have considerable
motion imparted to it.
This we attain by mounting an additional lever 55 (or 55a), or more than one
additional lever may be employed as will readily be seen, to oscillate upon the pivotal
pin 56 and joining said lever 55 (or 55a) to the lever 54 (or 54a) by the projecting
pin 57 (57a) which is made to operate within a slot formed near the fulcrum of said
lever 55 (55a) as shown by fig. 29. To the outer end of said lever 55 (55a) is joined
the rod 58 (58a) which imparts motion to the operating catch in the common well
known manner, and with the purchase obtained by the extra leverage furnished by
said lever 55 as will readily be understood the desired effect is produced.
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 rod 16, the lever 17, pin 19 formed to operate within a slot made in said
lever 17, rod 20 with its yielding spring 21, catches 22 and 23 formed and coupled
together in the well known manner, cylinder 24 and mechanism for effecting a
reversion in the direction of movement of the pattern surface used in connection with
the dobby, in combination all being arranged to operate in the manner and to the end
as substantially set forth.
2. A crank having two sweeps 12 and 12a arranged to operate dobby and Jacquard
mechanisms simultaneously, means for effecting a reversion in the directions of motion
of said dobby and Jacquard mechanisms and the parts ed, eef and g employed for
imparting motion to the shuttle box operating mechanism, in combination the same
being arranged to operate in the manner and for the purpose substantially as
specified.
3. The rods 25, 25a, picking tappits 26, 26a, bracket or joining piece 27 formed and
constructed as described, springs 28 and 28a and plug 29 in combination, said parts
being arranged and constructed to perform the functions substantially in the manner
and for the puposes as herein set forth and as illustrated by the accompanying
drawings.
4. The plug 29, employed in connection with the other parts herein described for
the purpose of engaging and disengaging the picking mechanism, and means whereby
the operative may easily operate said plug substantially as herein described.
