Improvements in Warp-weaving Machines, sometimes known as
Warp-knitting or Warp Machines.
1, ARTHUR PAGET, Mechanical Engineer, of Radmoor, Loughborough, in the
County of Leicester, do hereby declare the nature of this invention to be as
follows:-
The object of this invention is to make certain improvements in warp-weaving
machines, sometimes known as warp-knitting or warp-machines using a separate
thread or threads to each needle.
The first part of my invention consists of the method of and mechanism for
imparting the necessary motions to the needles by attaching them to sliding bits,
which sliding bits are moved backwards and forwards by a suitably shaped bar
actuated by another bar with wedges or inclines attached to it or formed in it,
which bar with its wedges, or inclines, when it is caused to slide to and fro length-
ways in the machine, causes the needles all across the machine to move backwards
and forwards equally and synchronously.
The second part of my invention consists of the method of and mechanism for
pulling the loops over the heads of the needles by the use of hooks of thin plate
sliding in grooves in a bar, and caused to have the necessary motions up and down
by a suitably shaped bar which is actuated by wedges or inclines attached to or
formed in another bar sliding to and fro endways in the machine.
The third part of my invention. consists of the method of and mechanism for
varying the lengths of loops pulled by the needles and held by the hooks by moving
parts of the "paths" of the cams which effect the movements of the needles and
hooks, such movements of the parts of the "paths" of the cams being effected
by connecting-rods, sliding-wedges and a rod projecting at the end of the cam-
shaft, the said rod being moved to and fro in the direction of the axis of the
cam shaft. by a lever or other suitable means and so varying the throws of
the cams.
The fourth part of my invention consists of the method of and mechanism for
reversing the action of the ratchets which produce the "shogging," or endwise
movements, of the bar carrying the thread-troughs or thread-guides by means of
sliding push-pieces, worked by cams, wedges or levers and brought into action
automatically after any desired number of movements of the thread-troughs or
thread-guides in either direction.
12
The fifth part of my invention consists of the method of and mechanism for
varying the number of "shogs, or end wise movements to the right and left, of
the bar which carries the thread-troughs or thread-guides, by the use of drop-push-
pieces attached to the ends of the sliding-push-pieces which reverse the action of
the ratchets which produce the said "shogging" movements.
The sixth part of my invention consists of the method of and mechanism for
reversing the action of the ratchets which produce the "shogging," or endwise
movements, of the bar carrying the thread-troughs or thread-guides, by means of
inclines linked together, or attached to or formed upon the opposite sides of a suit-
able chain, such chain or linked inclines being caused to move by suitable means
and to act, by means of a suitable connecting rod, direct upon the frame carrying
the said ratchets and thus reversing their action after any desired varying number
of “shogs” of the thread-troughs or thread-guides in either direction.
The seventh part of my invention consists of the method of and mechanism for
regulating and equalising the tension on the threads coming from the "creel" to
the thread-troughs or thread-guides by passing the threads over one set of bars

page_text: and under another set of bars, one or both of these sets of bars being capable of
being cambered adjustably by a "bowstring-arrangement," the arrangement of the
bars being such that when the two sets of bars are taken asunder to allow of
threading threads between the two sets, the slack of all the threads left by the
removal of the bars shall be taken up so as to prevent the threads getting entangled
or crossed, the said taking up of the slack of the threads being effected either by
the weight of the threads coming from the "creel" or in cases where it is necessary
by a weighted roller or bar.

Improvements in Warp-weaving Machines, sometimes known as
Warp-knitting or Warp Machines.
I, ARTHUR PAGET, Mechanical Engineer, of Radmoor, Loughborough, in the
County of Leicester, 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 :-
Fig. 3 is
The object of this invention is to make certain improvements in warp-weaving
machines, sometimes known as warp-knitting or warp machines, using a separate
thread or threads to each needle. Figs. 1 to 4 Sheets 1 to 4 show four views of
such a machine. Fig. 1 is a pari front view. Fig. 2 is a plan of same.
an end view, & Fig. 4 is a part general section showing the principal working parts.
A. A. are the needles which are moved in the directions of the arrows A. 1. A. 2 by
means hereinafter described. B. Bare the hooks which are moved in the directions
of the arrows B1. B2 by means hereinafter described. C. C. are the thread-
troughs" or "thread-guides."
A, B, and C are all three shown more clearly and enlarged in Figs. 5 to 15
Sheets 5 and 6. The "thread-troughs" CC are caused to move or "shog" across
the stems of the needles as desired by means hereinafter described. E is the
presser" which is caused to move in the direction of the arrow E1 by means of
suitable springs, and in the direction of the arrow E2 by means of a suitable
"wedge-bar" E 3, which carries suitable wedges or inclines E4, which wedges
engage with corresponding wedges upon the said "presser" E in such a manner
that when the wedge-bar E3 is moved lengthways in one direction the said
wedges E4 cause the presser E to descend and press the needles or "needle-beards"
whereas when the wedge bar E3 is moved lengthways in the opposite direction
with the wedges E4 the said "presser" E will then be lifted above the needles or
the "needle-beards." The necessary motions of the "wedge-bar" E3 arc imparted
by means of the cam E5 through the lever E 6. The motions and method of
actions of the three primary parts (i.e. the "thread-troughs" C, the needles A and
the hooks B) will be understood by referring to Figs. 11 to 15 Sheets 5 and 6
where the said primary parts are shown enlarged. After the completion of a row
of loops of the fabric being woven, the needles A come forward from the position
shown in Fig. 14 in the direction of the arrow A 2 Fig. 11, until the points of the
"needle-beards" have clearly passed (and are in front of) the "thread-troughs" C,
and this most forward position of the needles is shown in Fig. 11.
During the movement forward of the needles, and directly after the "needle-
beards" have passed, from under the "presser" E the said " presser" E is caused
to begin to descend and the "presser" E then descends until it presses upon, and
holds down the "needle-stems as shown in Fig. 11. The "thread-troughs "Care
then moved shifted "―or "shogged" across the needles so that each thread is laid
over and partly round the stem of one needle while the needles are in the most
forward position as shown in Fig. 11. The "presser" E is then lifted clear of the
needles as shown in Fig. 12. The needles then retire in the direction of the

page_text: arrow A.

the threads last laid on and over the needle-stems.

ns
The presser E then descends upon and "presses "the "needle-beards
shown in Fig. 13. The needles A then continue to retire until the points of the
"needle-beards" have entered into the previously formed row of loops, or as it is
ordinarily termed the previously formed row of loops is "landed" on the tops of the
beards of the needles. When the needles A have retired to this point the
presser" E then begins to rise and leaves the "needle-beards" so that the needle-
heads will pass under the "presser" without being "pressed."

"
3:
At the same time the "hooks" B. are caused to rise from the position shown in
Fig. 13 to the position shown in Fig. 14, the "presser" remains in this raised
position until the needles again come forward to receive a fresh row of loops
and the needle-beards" have passed forwards under the " presser" so that the
"needle-beards" are not "pressed as the needles are moved forward.
:
After the loops are "landed" the needles continue to retire and a fresh row of
loops is then pulled through the previously formed row of loops (as shown in Fig. 14).
When the last formed row of loops has been pulled by the needles through the
previously formed row of loops the "hooks" B are caused to move in the direction
of the arrow B1 Fig. 14 and then during a portion of their descent they will in
some classes of work assist in pulling the previously formed row of loops over the.
"needle-heads" and then when the needles again begin to come forward to receive
a fresh row of loops the hooks B continue to. descend until the needles have
reached the position shown in Fig. 15.
The said hooks then hold down and hold back the previously formed row of
loops and the last formed row of loops during the whole time that the needles
continue to come forward in order to be ready to receive from the "thread-
troughs C. a fresh row of loops as shown in Fig. 11.
::
The first part of my invention which I will describe consists of the method of
and mechanism for imparting the necessary motions to the needles by attaching
them to sliding-bits, which sliding-bits are moved backwards. and forwards by a
suitably shaped bar actuated by another bar with wedges or inclines attached to
it or formed in it, which bar with its wedges, or inclines, when it is caused to slide
to and fro lengthways in the machine, causes the needles all across the machine to
move backwards and forwards equally and synchronously.
Figs. 17, 18 and 19 Sheet 7 show this arrangement.
Fig. 17 is a view of part of the needle bar (looking down upon it in the direction
of the arrow A3 shown in Figs. 4 and 18 Sheets 4 and 7) together with some
adjacent parts. Fig. 18. is a section on the line Z. Y. (Fig. 17) and Fig. 19 is a
view looking in the direction of the arrow A4 (Figs. 17 and 18).

"
A. A are the needles which slide in suitable grooves in the top of the main-bar D.
These needles are each soldered or otherwise fastened to a sliding-bit A 5. For
the sake of clearness only four needles are shown in Figs. 17 and 19 but it will be
readily understood that there are needles side by side at a certain pitch or gange
across the whole width of the machine. A6 is a suitably shaped needle-bar which
carries and supports the sliding-bits A. 5. A. 7 are wires one between each sliding-
bit and the one next to it, which wires keep the sliding-bits upright and the correct
distance apart. A 8 is a bar for holding down the sliding-bits. This bar A. 8
slightly presses upon the sliding-bits A5 and keeps them in their places, and for
the sake of clearness this bar A8 is not shown in Fig. 17. The said bar A 8 can
be lifted at pleasure (for removing needles &c.) by means of the wedge-bar A 9,
Fig. 4, and the wedges or inclines A 10 (Fig. 4 Sheet 4) or any other suitable
arrangement. A 11 is another bar which has two or more wedges or inclines or
inclined-grooves A. 12 (Fig. 17) attached to or formed in it.
Suitable inclined-blocks or brackets A. 16 are attached to the needle bar A 6 and
these inclined blocks or brackets fit into and slide easily in the wedges or inclines
or inclined grooves A 12 when the bar A. 11 and the inclined grooves A 12 are
moved in the directions of the arrows A. 13 and A 14. The bar A 11 is caused

page_text: to slide to and fro in the directions of the arrows A 13, A 14, (Fig. 17)
and when so doing the wedges or inclines A. 12 cause the needle-bar A.6 and
consequently all the needles all across the machine to move backwards and forwards
in the directions of the arrows A 1. A.2. All the needles moving equally and
synchronously all across the machine. The necessary motions are imparted to the
bar A 11, by means of the cam A 15 (Figs. 2 and 3) which is fixed to the main
shaft G, or the bar A 11 may be 'moved by any other convenient means.
The second part of my invention which I will describe consists of the method of
and mechanism for pulling the loops over the heads of the 'needles by the use of
hooks of thin plate sliding in grooves in a bar, and caused to have the necessary
motions up and down by a suitably shaped bar which is actuated by wedges or
inclines attached to or formed in another bar sliding to and fro end-ways in the
machine.
Figs. 20, 21 and 22, Sheet 8 show this arrangement. Fig. 20 is a view of part
of the hook-bar looking in the direction of the arrow B3 (Figs. 4 and 21) together
with some adjacent parts. Fig. 21, is a section on the line X. W. (Fig. 20.) and
Fig. 22 is a view looking in the direction of the arrow B 4 (Figs. 20 and 21).
B. Bare the hooks of thin plate, which slide in grooves B5 in the main
bar D and are held in these grooves by the "hook-plates" B6. B7 is a suitable
shaped hook-bar." A suitable groove B8 in this bar receives the ends of the
hooks B. 19 Fig. 20. is one of two or more wedges or inclines attached to or
formed in another bar B 10. Suitable inclined blocks or brackets B 11 are attached
to the hook-bar" B 7.
These inclined-blocks or brackets fit into and slide easily in the wedges or inclines
or inclined-grooves B9. The bar B10 is caused to move to and fro in the direc-
tions of the arrows A 13 A.14 (Fig. 20.) and when so doing the wedges or
inclines B9 cause the "hook-bar" B7 and consequently the hooks also to move
up and down in the directions of the arrows B1 and B2. The necessary motions
are imparted to the said wedge-bar B10 by means of the cam B 12 (Figs. 1,
2 and 3.) which is carried by or fixed upon, the main shaft G, or the said bar B10
may be moved by any other convenient means.
The third part of my invention which will describe consists of the method
of and mechanism for varying the lengths of loops pulled by the needles and held
by the hooks by moving parts of the "paths" of the cams which effect the move-
ments of the needles and hooks, such movements of the parts of the "paths" of
the cams being effected by connecting-rods, sliding-wedges and a rod projecting
at the end of the cam-shaft, the said rod being moved to and fro in the direction of
the axis of the cam shaft by a lever or other suitable means and so varying the
throws" of the cams.
C
Figs. 23, 24 and 25, Sheets 9 and 10 show this arrangement. Fig. 23 is a view
looking at the face of a needle-cam A 15 (see also Fig. 1) with the arrangements
for adjusting portions of the "path" of the said cam A 15. Fig. 24 is a view of
part of the same looking in the direction of the arrow L Fig. 23. Fig. 25 is a
part section of the main shaft of the machine and some adjacent parts.
L1 and L2 Figs. 23 and 24 are the parts or segments of the "path" of the
cam A 15 which effect the lengths of the loops pulled by the needles. The said
part 11 is hinged or jointed at its end L3 and the said part L 2 is hinged or
jointed at its end L4 to the body or main part of the cam A. 15.
The other ends of the said parts L1 and L2 being so fitted or tongued together
that they are free to slide side by side in such a manner that when one moves the
other moves also and that when they are turned upon the centres L3 and L4 so
that the "path" or acting surfaces of these parts or segments are in the position
shown by dotted lines in Fig. 23 the radius of this portion of the cam is increased
and thus the amount of motion of the needle wedge-bar A 11 herein before described
(and consequently of the needles A) is also increased without breaking the continuity
of the path of the said cam.

page_text: A suitable connecting-rod L5 is connected to a suitable arm L 6 which is formed
upon or attached to the segment L2. The end L 7 of the said connecting-rod L5
is so shaped that it fits into and slides in a sliding-wedge or grooved incline L 8.
It will be evident that when the said sliding-wedge L8 is caused to move in the
direction of the arrow L9 (Fig. 25) the segments L1 and L2 will be moved into
or towards the position shown by dotted lines in Fig. 23 and the radius of the cam
at this part is increased and when the said sliding wedge LS is moved back again
in the direction of the arrow L 10 the said radius is decreased, and thus by moving
the sliding wedge L 8 the lengths of the loops pulled by the needles are varied at
pleasure. In like manner a sliding-wedge E 13 Fig. 25 with similar arrangements
to those described above will vary the amount of motion of the hooks.
The two sliding wedges L8 and E 13 (Fig. 25) are suitably connected together
and connected to a rod L 11 which said rod projects at the end of the cam shaft G.
The said rod L11 is suitably attached to a lever L 12 which works upon a
centre L 13. Thus it will be seen that by moving the end of the lever L 12 in the
direction of the arrow L 14 the lengths of loops pulled by the needles and held by
the hooks are increased and by moving the said lever in the direction of the
arrow L 15 the lengths of loops pulled and held are decreased.
It will be evident that instead of moving the said lever L 12 by hand it may, in
some cases, be moved automatically by the machine itself by attaching the end of
the said lever L 12 to a 65
Jacquard apparatus, or the said lever L 12 may be moved
by suitable mechanism worked or set in motion by an endless chain having suitable
inclines upon it, or by any other suitable well known means.
6:
The fourth part of my invention which I will describe consists of the method of
and mechanism for reversing the action of the ratchets which produce the
shogging," or endwise movements, of the bar carrying the "thread-troughs" or
thread-guides" by means of sliding push pieces, worked by cams, wedges or levers
and brought into action automatically after any desired number of movements of
the thread-troughs" or "thread-guides" in either direction.
66
CC
Figs. 26, 27 and 28 Sheets 11 and 12 show this arrangement. Fig. 26 is an
clevation of the "shogging" apparatus (for producing the shogging" or endwise
movements of the "thread-troughs" C.) looking from the back of the machine.
Fig. 27 is a part plan of same and Fig. 28 is an end view of same looking in the
direction of the arrow V (Fig. 26).
C2 is the trough-slide-bar" to which is attached the trough-bar" C 1 in
which the "thread-troughs" C are fastened. 03 is a suitable rack fastened to the
"trough-slide-bar" C2. C4 is a pinion which gears into the rack C3 and is
carried by the shaft C5. Upon the other end of the shaft C5 is a sector C6
which is provided with two sets of teeth C7 and C8 (see Fig. 26) which are
formed or arranged so as to be driven by the ratchet C 9 in one direction and by
the ratchet C 10 in the opposite direction as hereinafter described. C 9. C 10 are
two suitably shaped ratchets which are carried by a suitable frame or ratchet-
carrier C1 Suitable motion is imparted to the said ratchet-carrier C 11 in the
directions of the arrows C 12 and C 13 Fig. 26 by means of the lever C 15 actuated
by the cam C 14. The two ratchets CO, C 10 are so arranged that when the
ratchet C9 is in gear with the teeth C7 the ratchet C 10 is out of gear, and when
the ratchet C10 is in gear with the teeth C8 the ratchet C9 is out of gear. Upon ⚫
the top of the ratchet-carrier C11 is a vee-shaped nose C 16 above this is a
lever 17 which works upon the pin or centre C 18. It will be seen that the said
lever C 17 has a vee-shaped nose which engages with the vee-shaped nose C 16 on
the ratchet-carrier C 11 and is kept in contact with it by the spring C 19. It will
also be seen (see Fig. 26) that the vee-nose of the lever C 17 pressing upon the
vee-nose CIG will keep the ratchet C9 in gear with the teeth C7 while the
ratchet C 9 is moving up and down and until the ratchet-carrier C 11 is caused by
some means to move sideways in the direction of the arrow C 20 and thus it will
be seen that when the top end of the ratchet-carrier C 11 is moved in the direction.
of the arrow C 20 (the bottom end working in and on the centre screw C21) the

page_text: ratchet C 9 is thrown out of gear, and the ratchet C10 is thrown into gear, and
the vee-nose of the lever C17 then presses upon the opposite side of the
vec-nose C 16 and thus keeps the ratchet C10 in gear until the ratchet-carrier C 11
is again moved in the opposite direction to the arrow C 20 and thrown over so that
the ratchet C9 is again in gear. Thus it will be seen that when the ratchet C9
is in gear with the teeth CT the trough-slide-bar C2 and the "thread-troughs" C
are moved or shogged" in one direction and when the ratchet C 10 is in gear the
"thread-troughs "are "shogged." in the opposite direction. The object of this
part of my invention is to move the ratchet-carrier C 11 so as to bring either the
ratchet C9 or the ratchet C 10 into gear so as to reverse the "shogging" move-
ments of the "thread-troughs" C automatically after any desired number of
movements of the "thread-troughs" in either direction.
::
H. Hare two sliding push pieces which are free to slide upon the studs or
pins H 2 and H 3.
"
H 4. H5. are two adjustable arms or fingers attached to the sector C 6 in such a
manner that when the ratchet C 10 is in gear and it has "shogged or racked the
sector C 6 a certain number of teeth, the end of the arm H4 will come into contact
with the end J 4 of the sliding push-piece H and push it into the position shown
in Fig. 26.
H6. H 7. is a double arm or "bell-crank "lever working upon the pin H 8, the
arm E 6 being in contact with and worked by the cam H 9. When the sliding-
push-piece is moved (by the arm Ht on the sector C6) it is so adjusted that its
end passes between the end H. 7 of the lever EI 6. H 7 and a suitable projection H. 10
on the ratchet-carrier C 11. Then as the main shaft G revolves the cam H 9.acts
upon the lever H 6. H7 which acts upon the sliding-push-piece H which in turn
acts upon the projection H 10 on the ratchet-carrier Cil and throws the ratchet C 9
into gear.
In like manner when the ratchet C9 is in gear the arm H5 on the sector C 6
will move the push-piece H 1 in such a manner that its end passes between the end
of the lever II 11 (working upon the pin H12) and the projection H 13 on the
ratchet-carrier C11, and the ratchet C9 is then thrown out of gear and the
ratchet C10 into gear and the movement of the "thread-troughs" is reversed, and
thus by adjusting the positions of the two arms H4 and EI 5 on the sector C6 the
ratchets C9 and C10 are reversed automatically after any desired number of
movements of the "thread-troughs" in either direction.
The fifth part of my invention which I will describe consists of the method of
and mechanism for varying the number of "shogs," or endwise movements to the
right and left, of the bar which carries the "thread-troughs" or "thread-guides;"
by the use of "drop-push-pieces" attached to the ends of the "sliding-push-pieces"
which reverse the action of the ratchets which produce the said shogging
movements.
Figs. 26 to 30 (Sheets 11 and 12) show this arrangement. Figs. 26 to 28 are
three views of the shogging" apparatus as herein before described.
165
66
Fig. 29 is an elevation, and Fig. 30 is a plan of a "sliding-push-piece" H on a
larger scale than Figs. 26. to 28. It will be seen that the sliding-push-piece"
shown in Figs. 29 and 30 consists of two parts or members the lower part (or
sliding-push-piece ") H described in the fourth part of this invention, and the
upper part or drop-push-piece" J. The said "drop-push-piece" J is hinged or
jointed to the sliding-push-piece "I by the pin JL. A suitable spring J2 acts
or presses upon the "drop-push-piece "J and tends to keep it in the position as shown
by full lines in Fig. 29, but the drop-push-piece" J is free to be lifted by means
of a cord J3 (Figs. 29 and 30) or other suitable means into the position shown by
dotted lines in Fig. 29.
<:
The adjustable arms H4 and H5 on the sector C6 (Fig. 26) and the "drop-
push-piece Jand. the sliding-push-piece" H are so adjusted that when the
drop-push-piece" J is lifted into the position shown by dotted lines in Fig. 29 the
end of the arm H-4 (Fig. 26) will pass under the end J 4 (Figs. 29 and 30) of

page_text: the said "drop-push-piece" J and so will not push the "sliding-push-piece" H until
the sector C 6 has been racked a certain number of teeth further round so as to
bring the arm H 4 into contact with the enl H 14 of the "sliding-push-piece" H,
and thus it will be seen that by lifting the "drop-push-piece" J into the position
shown by dotted lines in Fig. 29. the sector C6 (Fig. 26) will be racked a greater
number of times or turned through a greater angle (and consequently the "thread-
troughs will be "shogged" a greater number of times in one direction) before
the ratchet C 10 is brought into action, and by dropping the "drop-push-piece" J
into the position shown by full lines in Fig. 29, the sector C 6 will be racked a less
number of times and consequently the thread-troughs" C will be shogged a less
number of times in one direction before they are "shogged" in the opposite
direction.
::
22
It will be evident that in a similar manner two or more "drop-push-pieces
can be hinged or jointed to the "sliding-push-pieces "H and H 1 and arranged in
such a manner that each "drop-push-piece "can be lifted separately and when so
lifted it will allow the sector C6 to move through a greater number of teeth
before the movement of the sector C 6 is reversed.
"
Thus it will be seen that by lifting and lowering these "drop-push-pieces" the
number of "shogs or endwise movements to the right and left of the bar which
carries the thread-troughs "C is varied at pleasure. It will also be evident that
the said "drop-push-piece or drop-push-pieces can be lifted automatically by
simply attaching the cords or wires to a Jacquard" apparatus or by suitable
mechanism to an endless chain with suitable inclines upon it, or by any other
suitable well known means.

The sixth part of my invention which I will describe consists of the method of
and mechanism for reversing the action of the ratchets which produce the
shogging," or endwise movements, of the bar carrying the "thread-troughs" or
thread-guides, by means of inclines linked together, or attached to or formed
upon the opposite sides of a suitable chain, such chain or linked inclines being
caused to move by suitable means and to act, by means of a suitable connecting-
rod, direct upon the frame carrying the said ratchets and thus reversing their
action after any desired varying number of "shogs" of the "thread-troughs or
"thread-guides" in either direction.
?>
Figs. 31 to 34 (Sheets 13 and 14) show this arrangement which is similar to
the arrangement for "shogging" the "thread-troughs as shown in Figs. 26 to 28
(and hereinbefore described) excepting those parts of this arrangement which
cause the reversal of the action of the ratchets C9 and C 10. Fig. 31. is a part
elevation of this arrangement. Fig. 32 is a part plan of same. Fig. 33 is a side
view of same and Fig. 34 is a section of part of same as indicated.
C1 is the ratchet-carrier which carries the ratchets C9 and C 10 which work
into or act upon the sector C 6 as herein before described.
Figs. 31, 32 and 34 show a chain K such as herein referred to. As shown, it
consists of a number of links with inclines or wedge-shaped surfaces K2 K3,
formed upon their sides as shown in Figs. 31 and 32, the said chain is caused to
advance one link at a time in the direction of the arrow K4 by means of a suitable
ratchet K5 which is worked by the lever K 6 and the cam 7 or other suitable
means. The chain is thus caused to advance one link for each revolution of the
main-shaft G. A. suitable connecting-rod K 8 is attached at one end K9 to the
ratchet-carrier C 11 the other end of the said connecting-rod K 8 is provided with
two suitable fingers or lugs K 10 K 11 which are arranged and adjusted in such a
manner that when the ratchet-carrier C 11 is in such a position that the ratchet C 9
is in gear, the finger K 10 is close to one side of the said chain K and the
finger K 11 is clear away from it, and when the said ratchet-carrier is in such a
position that the ratchet C 10 is in gear the finger Kil is close to the other
side of the said chain K and the finger K 10 is clear from it.
The said inclines K2 K2 and K3 K3 are so formed and arranged that when
the ratchet C9 is in gear with the sector C6 and the said chain K is caused
-

page_text: to advance so many links that an incline K3 comes into contact with the finger K 10,
the finger K10 and consequently the connecting-rod K8 is moved by the said
incline K 3 in the direction of the arrow K 12 and the ratchet C9 is thrown
out of gear and the ratchet C10 is thrown into gear and the motion of the
sector 6 (and consequently the " thread-troughs also) is reversed. In like
manner the inclines K 2. K2 act upon the finger K 11 and throw the ratchet C9
into gear and the ratchet C 10 out of gear. It will thus be seen that by suitably
arranging inclines K 2. K2 and K 3. K 3 upon the sides of a suitable chain, the
action of the ratchets C9 and C 10 can be reversed after any desired varying
number of shogs" of the thread-troughs in either direction.
"
If desired the chain can be made and the apparatus arranged so that the said
chain shall be advanced two or more links for each revolution of the machine
or the lengths of the links can be increased or diminished as may be most
suitable for each of the various classes of work which can be made by the
machine.

The seventh part of my invention which I will describe consists of the method
of and mechanism for regulating and equalizing the tension on the threads coming
from the creel" to the "thread-troughs or thread-guides by passing the
threads over one-set of bars and under another set of bars, one or both of these
sets of bars being capable of being cambered " adjustably by a "bowstring-
arrangement," the arrangement of the bars being such that when the two sets of
bars are taken asunder to allow of threading threads between the two sets, the
slack of all the threads left by the removal of the bars shall be taken up so as to
prevent the threads getting entangled or crossed, the said taking up of the slack of
the threads being effected either by the weight of the threads coming from the
creel" or in cases where it is necessary by a weighted roller or bar.
Figs. 35 to 37 Sheets 15 and 16 show this arrangement. Fig. 35 is a part
elevation and cross section of this apparatus with some adjacent parts. Fig. 36 is
a view of part of the same looking in the direction of the arrow M (Fig. 35),
and Fig. 37 is a plan of the same parts.
M1. M1 are a set of suitably shaped bars reaching across the whole width of
the machine. These bars are held at suitable distances apart by any convenient
means and are supported by suitable brackets M 2. M 3. M3 are another set of
bars which also reach across the whole width of the machine and are held at
suitable distances apart by any convenient means.
The set of bars M 3. M 3 are supported by the rods M 6. M 6 which are attached
to a bar M 7 which is free to turn or swing upon the pivots M8 (Fig. 35) or by
any other suitable means. The set of bars M3. M3. are held in the position
shown by the spring latches M 14. M. 14 and when it is desired to pass threads
between the two sets of bars M 1. M1 and M 3. M 3, the two said latches M 14. M 14
are moved into the position shown by dotted lines in Fig. 35 and the set of
bars M3 M 3 can then be moved in the direction of the arrow M5 Fig. 35
while the threads from the "crcel" are passed through the reed M13 Fig. 35
and over the set of bars M 1. M 1. The set of bars M 3. M 3 is then moved in
the direction of the arrow M4 (Fig. 35) until their edges press upon the threads
from the "creel" and press them a certain distance between the set of bars M 1. M 1.
(depending upon the amount of tension required on the threads) when the spring
latches M 14. M 14 move into the position shown by full lines in Fig. 35 and keep
the said set of bars M 3. M 3 in position.
The amount of pressure exerted upon the threads as they pass between the two
said sets of bars M 1. M 1. and M 3. M 3 and consequently the amount of tension
upon the threads is governed and regulated by the distance the set of bars M 3 M 3,
are made to go between the set of bars M1 M1 and this distance is regulated and
governed by the latches M 14. M 14 which are regulated and governed by the
screws M 9. M 9.
In some cases when drawing the threads from some forms of "creel the
threads that are nearest to the centre of the machine have less tension or drág

page_text: upon them when brought from the "creel" than those threads nearer the ends of
the machine. In order to compensate for this difference and render the tension or
drag upon the threads equal and regular all across the machine a suitable wire or
bowstring" M 10 is stretched by means of suitable nuts and brackets from end to
end of the said set of bars M3 M3. A. suitable bracket or brackets M 11 enables
the "bowstring
"M 10 to exert force upon the set of bars M 3. M3 and so
"camber" or, bend them so as to make them exert more tension or drag upon the
centre threads than upon the threads towards the ends of the machine and thus by
adjusting the nuts M 12 M 12. at the ends of the bowstring M10 the
bars M 3. M 3 can be more or less "cambered "at any part or parts desired and
the tension thereby regulated as desired. In some cases a similar arrangement of
When the set of
bowstring may be applied to the set of bars M 1. MI.
bars M 3 M 3 is moved in the direction of the arrow M5 so as to allow threads to be
threaded between the two sets of bars M I. MI and M 3. M3 it is desirable that the
slack of all the threads left by the removal of the set of bars M 3. M3 should
be taken up so as to prevent the threads getting entangled or crossed. This in
some cases is effected by the weight of the threads themselves, but in cases where
this is insufficient the threads are passed over the stationary rollers M 15, M 15,
and under the sliding roller M 16, this being free to slide up and down in the
grooves M 17.
The weight of the said roller M 16 can be adjusted by any suitable
and convenient means, so that when resting on the threads it is not sufficient to
draw thread from the "creel," but when the two sets of bars M 3. M.3 and M.1. M-1-
are taken asunder to allow of threading threads between the two sets of bars the
slack of all the threads left by the removal of the bars will then be taken up by
the roller M 16 drawing the "slack" of the threads down between the two
rollers M 15. M 15.
Having now particularly described and ascertained the nature of my said
invention, & in what manner the same is to be performed, I desire it to be
understood that I do not confine myself to the exact details herein set forth as such
may be varied & modified without departing from the principle thereof but what
I claim as my improvements in Warp-weaving-machines" sometimes known as
"Warp-knitting" or "Warp-machines" are:-
::
First. The method of & mechanism for imparting the necessary motions to the
needles by attaching them to sliding-bits, which sliding-bits are moved backwards
and forwards by a suitably shaped bar actuated by another bar with wedges or
inclines attached to it or formed in it, which bar with its wedges, or inclines, when
it is caused to slide to & fro lengthways in the machine, causes the needles all
across the machine to move backwards & forwards equally & synchronously,
substantially as hereinbefore described with reference to Figs. 1 to 4 Sheets 1 to 4
& Figs. 17 to 19 Sheet 7 & others of the drawings.
Second. The method of & mechanism for pulling the loops over the heads of the
needles by the use of hooks of thin plate sliding in grooves in a bar, & caused to
have the necessary motions up & down by a suitably shaped bar which is actuated
by wedges or inclines attached to or formed in another bar sliding to & fro
endways in the machine, substantially as hereinbefore described with reference to
Figs. 20 to 22 Sheet 8 & others of the drawings.
Third. The method of & mechanism for varying the lengths of loops pulled by
the needles & held by the hooks by moving parts of the "paths" of the cams
which effect the movements of the needles & hooks, such movements of the parts of
the "paths" of the cams being effected by connecting rods, sliding-wedges & a rod
projecting at the end of the cam-shaft, the said rod being moved to & fro in the
direction of the axis of the cam shaft by a lever or other suitable means & so
varying the "throws" of the cams, substantially as hereinbefore described with
reference to Figs. 23 to 29, Sheets 9 & 10, & others of the drawings.
Fourth. The method of & mechanism for reversing the action of the ratchets
which produce the "shogging or endwise movements of the bar carrying the

or
Fifth. The method of & mechanism for varying the number of "shogs
end wise movements to the right & left of the bar which carries the thread-
troughs or thread-guides," by the use of "drop-push-pieces" attached to the
ends, of the sliding-push-pieces which reverse the action of the ratchets which
produce the said "shogging".movements, substantially as hereinbefore described
with reference to Figs. 20 to 30 Sheets 11 & 12 & others of the drawings.
Sixth. The method of & mechanism for reversing the action of the ratchets
which produce the "shogging" or endwise movements of the bar carrying the
"thread-troughs" or thread-guides," by means of inclines linked together, or
attached to or formed upon the opposite sides of a suitable chain, such chain or
linked inclines being caused to move by suitable means & to act, by means of a
suitable connecting-rod, direct upon the frame carrying the said ratchets & thus
reversing their action after any desired varying number of " shogs" of the
"thread-troughs or thread-guides in either direction, substantially as herein-
before described with reference to Figs. 31 to 34 Sheets 13 & 14 & others of the
drawings.

Seventh. The method of & mechanism for regulating & equalising the tension
on the threads coming from the "creel" to the "thread-troughs or "thread-
guides" by passing the threads over one set of bars & under another set of bar,
one or both of these sets of bars being capable of being "cambered " adjustably by
L howstring-arrangement" the arrangement of the bars being such that when the
two sets of bars are taken asunder to allow of threading threads between the two
sets, the slack" of all the threads left by the removal of the bars shall be taken
up so as to prevent the threads getting entangled or crossed, the said taking up of
the "slack of the threads being effected either by the weight of the threads
coming from the "crecl" or in cases where it is necessary by a weighted roller or bar,
substantially as hereinbefore described with reference to Figs. 35 to 37, Sheets 15
and 16 and others of the drawings.
