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 construction and use of a " presser
notched or cut or built up with grooves or "tricks" for Hooks to slide or work in,
such a presser being centred or hinged or otherwise guided in such a manner that the
pressing-point or pressing-edge of the "presser can be made to advance and retire
to and from the needle beards by a cam or cams or other suitable means so that the
Needle-beards are pressed" at the right time and place as the Needles retire and the
beards are not pressed as the needles come forward to receive a fresh row of loops.
The second part of my invention consists of the construction and use of a
'presser" plain or notched or cut or built up with grooves or tricks for hooks to
slide or work in, such a presser being centred or hinged or otherwise guided in
such a manner that the pressing point or pressing edge of the presser can be made
to advance and retire to and from the "needle-beards" such movement boing
produced by forming upon or attaching to the said presser a number of "inclines" or
wedge-surfaces and fitting against these said "inclines" are a corresponding number
of similar inclines formed upon or attached to a suitable wedge-bar in such a manner
that when the said wedge-bar is moved in the direction of its length one way by a
cam or other suitable means, the inclines attached to the said wedge bar act upon
the inclines" attached to the presser in such a manner that the "presser" is forced
down on to the "needle-beards" and they are thereby "pressed" and when tho said
wedge-bar is moved in the opposite direction the presser is released and can be lifted
so that the "needle-beards" are not "pressed."
23
The third part of my invention consists of the construction and use of a moveable
presser" worked by inclines as in the second part of this invention its movements
being created and governed by a cam or other suitable means in such a manner that
the presser" is made to press upon the stems of the needles and hold them down
while the " thread-guides thread-guide-troughs"
or
"
are moved or shogged
across the needles and thus there is less danger that a needle (if it is strained or bent
or lifted or displaced) will be further displaced and injured by the said "thread-
guides" or thread-guide-troughs" as they are shogged." Then as soon as the
shog" is completed the presser is made to rise to the right height for being ready to
press" the "needle beards."

.:
The fourth part of my invention consists of the construction and use of a supple-
mentary hook-bar (for pulling or forming a fringe or row of extra long loops)
arranged across the front of the machine and behind the fabric. The said hook-bar
is actuated by a suitable shaft and by racks-and-pinions, chains, bands, or tapes or
other suitable means and the hook bar may be in some cases balanced by suitable
weights or springs in such a manner that when the said shaft is turned in one
direction the said hook-bar will rise into such a position that the hooks are nearly up
to the needles and their points touch the fabric. Then when the said shaft is turned in
the opposite direction the said hooks are caused to hook into the fabric and then
by continuing to turn the said shaft in the same direction a row of long loops
is pulled to any desired length to form a fringe after which the said loops are cut in
a suitable manner. The said shaft may be turned by a ratchet, ratchet wheel and

page_text: .
lever or by any other suitable means, or in some cases the motions of the said hook-
bar may be obtained by a rocking shaft and suitable levers or arms.
"
The fifth part of my invention consists of a method of imparting all the
necessary shogging motions to the thread-guide bar which carries the "thread-
guides ог tbread-trough-guides" &c. and consequently to the threads or warp by
means of a straight rack or racks cast où attached to, or cut in, the said bar in such
a manner that the teeth in the said rack or racks are of the same gauge or "pitch"
as the needles in the machine. Adjacent to this rack or racks I arrange two levers
or combination of levers which carry two "ratchets " or
"pawls." These two
"
"
"
"
**
دو
ratchets or "pawls" are so arranged that when the lever or levers to which they
are attached are moved in a certain direction, one of the said "ratchets or pawls
will engage with the said rack or one of the said racks, and cause it or them and
consequently the bar also to move a distance of one tooth or needle. These two
said "ratchets or "pawls" are also so arranged that when the one is moved it
causes the said rack or racks and consequently the "thread-guide-bar" with the
threads or. warp" to move or "shog" in one direction, and when the other
"ratchet" or (5.
pawl" is moved it causes the "thread-guide-bar" to move or "shog'
in the opposite direction. Thus by moving one or other of the said two levers or
combinations of levers the "thread-guide-bar
"2 is shogged one
tooth or needle at
a timo either to the right or left as desired. Adjacent to the two said levers or com-
bination of levers I arrange one or more suitably shaped cams fixed to the main shaft
(or to an auxiliary shaft of the machine) Between the said levers and cam or cams
I interpose a suitable "push-piece" in such a manner that when it is in one position it
connects the said cam or cams with one of the said levers and when in the other
position it connects the said cam or cams with the other of the said levers. Thus by
shifting the said "push-piece" the direction of the "shog" (or movement of the
"thread-guide-bar") is reversed. Upon or connected with the said "thread-guide-
bar" I arrange two suitable. adjustable stops in such a manner that when the said
thread-guide-bar" has "shogged" as many steps in one direction as desired, one of
the said adjustable stops moves (or causes to be moved) the said push-piece in to the
position necessary for reversing the "shog" Thus the number of "shogs" to the
right and to the left is governed by the said adjustable stops.
*
"
"
"
The sixth part of my invention consists of the construction and use of a cam and
other adjuncts as hereinafter described for imparting the necessary motions to the
"thread-guide-bar." This said cam imparts a reciprocating motion to a suitably guided-
rod so arranged that one end of the said rod engages with and is worked by the said cam
and the other end is forked or opened out so as to partly embrace a ratchet wheel,
each of the two ends of the said fork being suitably shaped so as to form two suitable
" ratchets or pawls" which can be made to engage with the said ratchet wheel at
or near opposite sides, the said forked end being sufficiently opened so that when the
said fork is moved to one side the one end or ratchet" or
pawl" is put into gear
and the other is put out of gear and vice-versa. Upon or connected with the said
ratchet wheel I arrange two suitable adjustable stops so that when one end or "ratchet"
or "pawl" of the said forked rod has racked the said ratchet wheel as many "shogs"
as desired in one direction, one of the said stops moves or causes to be moved the said
forked rod so that the one end is thrown out of gear and the other end is thrown into
gear
gear, and so the motion of the said "ratchet wheel is changed automatically as
desired. The said ratchet wheel may be connected to the "thread-guide-bar" by any
convenient means such as a pinion working into a rack or any other well known
method.
The seventh part of my invention consists of the construction and use (for imparting
the necessary motions to the "thread-guide-bar") of a can or cams with a
push-
piece "levers and "ratchets" or "pawls" in a similar manner to the fifth part of
my invention in combination with a ratchet wheel or wheels (or segments of same)
into which the said "ratchets or "pawls" work, the said ratchet wheel or wheels are
attached to a suitable shaft. The said "ratchets or "pawls" being carried by suitable
arms working upon the same shaft as the said "ratchet" wheel or wheels and inotion is
23
23

page_text: imparted to the said arms and "ratchets ** or ** pawls** by the said cam or cams through
suitable connecting rods, and the said "push-piece" which connects one or other of the said
connecting rods with the said cam or cams as governed by suitable stops upon the said
"ratchet" wheel or wheels.
"
.f
"
32
"
To the shaft which carries the said ratchet wheel or wheels is also fixed a toothed
wheel or a segment of the same. This toothed wheel or segment gears into a rack
upon the thread-guide-bar and thus each movement of the cam or cams is
transmitted through the said push-piece" levers "ratchets or "pawls" ratchet
wheel or wheels and toothed wheel or segment and rack to the said thread-guide-bar.
The eighth part of my invention consists of the construction and use of a cam or
cams for imparting the necessary motions to the "thread-guide-bar" suitably connected
to two arms or levers each of which carries a ratchet or pawl." The two said
" ratchets or "pawls" work into a suitable "ratchet" wheel or wheels (or segments
of same) at or near the opposite sides in such a manner that ono "ratchet" or "pawl"
will turn the ratchet wheel or wheels in one direction and the other "ratchet"
"pawl" in the other direction. Between the said "ratchets" or "pawls" and the
ratchet wheel or wheels I interpose a moveable shield or stop-piece in such a
manner that when moved in one direction it lifts, the one
ratchet" or pawl'
out of gear and lets the other into gear and when moved in the opposite direction
the acting ratchet or "pawl" becomes idle and what was the idle "ratchet " or
pawl" becomes the acting ratchet or is thrown into gear. Thus by moving the
interposed shield or stop piece the motion of the said "ratchet" wheel or wheels
is reversed.
<
"
::
"
<<
"
or
The said "ratehet" wheel or wheels may transmit its or their motion to the
thread-guide-bar" by any convenient means such as a rack and a pinion or two
steel tapes or chains fastened to the trough bar and to the opposite sides of a pulley
attached to the said "ratchet" wheel or wheels.
The above named moveable shield or stop may be moved as required by changing
the direction of motion of the said
ratchet"
wheel or wheels (and consequently
theshog" of the trough-bar) by suitable adjustable stops attached to or connected
with the said "ratchet wheel or wheels in such a manner that the said adjustable
stops automatically govern the number of "shogs" of the "thread-guide-bar" to the
right and left.
::
The ninth part of my invention consists of the construction and use (in combina-
tion with the apparatus for "shogging" the "thread-guide-bar" as referred to
in parts 5 to 8 of this invention) of a chain or of a suitably equally divided strap or
band moved in such a manner that it advances regularly one or more or less links or
divisions for each revolution of the machine.
Upon this chain, strap or band I arrange suitable "inclines" and in such a manner
that they engage with suitable levers and govern the order of the "shogging" or to
and fro movements of the "thread-guide-bar."
"
It will be evident that by suitably arranging the positions of the said inclines upon
the said chain, strap or band many variations of "shogs or movements of the
66 thread-guide-bar" in either direction may be made and consequently many variations
of patterns of work can be made automatically without stopping the machine.

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 :-
The object of this invention is to make certain improvements in warp, weaving

page_text: .
machines, sometimes known as warp knitting, or warp machines, using a separate
thread or threads to each needle.
The said improvements herein after described will be better understood by referring
to Figs. 1 to 16 sheets 1 to 8 which show all the necessary and important parts of
a machine of the class to which the said improvements are applicable.
Fig. 1 sheet 1 is a view of the left hand end of such a machine. Fig. 2 sheet 2 is
a view of the right hand or driving end. Figs. 3 and 4 sheets 3 and 4 are part front
views of same. Fig. 5 sheet 5 is a part plan of same. Fig. 6 sheet 6 is a
general cross section of the body, or chief part of the machine, showing the principal
working parts. Figs. 7 to 16 sheets 7 and 8 are enlarged views of parts of the
primary parts.
A A are the needles which are held in the needle-bar A¹.
To this bar A 1, and consequently to the needles A A also, motion is imparted in the
direction of the arrows A 2, A 3 by suitable cams A 10 on the main shaft D through the
arms or levers A 5 which are attached to the rocking shaft A 4. These arms transmit
the requisite movements to the needle-bar A 1 and needles A, through the joint-pins A 7
and the joint-arms A 6 which are attached to the back of the needle-bar A 1. BB are
the hooks (one of which works between each needle and the one next to it) which are
held in the hook-bar B 1. To this bar B1 and consequently to the hooks B also, motion is
imparted in the direction of the arrows B2 B3 by suitable cams B 9 on the main-shaft D
through the arms or levers B 5 which are attached to the rocking-shaft B 4. These
arms transmit the requisite movements to the hook-bar B1, and the books B through
the joint pins B 7 and the joint-arms B6 which are attached to the lower part of the
hook-bar B 1.
"
"
CC are the "thread-guide-troughs." (a plan elevation and three sections of one of
such "thread-guide-troughs" are shown in Figs. 12 to 16 sheet 8). These "troughs
are attached to the "trough-bar or thread-guide-bar" C1, to which the necessary
motions (in the direction of the arrows C2, C3 Fig. 5) are imparted by any of the
several arrangements herein after described, or by any other of the well known
methods.
When the "thread-guide-troughs" have had the necessary motions imparted to
them, they can (in cases where this is necessary) be locked in position by the thread-
guide-bar-lock," as shown in these drawings at C5, C6 and C7 Figs. 4 and 5 sheets 4
and 5, or by any other well known method. E is the " presser which is suitably
attached to the uain-bar F. (as is herein after described). G is the knocking-over-
bar against which both the needles A and the hooks B rest and work.
The motions and method of action of the four primary parts of the machine (that
is those parts which manipulate the threads viz. ;-The "thread-guide-troughs" C.
The needles A. The hooks B and the knocking-over-bar G) will be best understood
by referring to Figs. 7 to 11 sheets 7 and 8 where the said primary parts are shown
enlarged. The needles A come forward in the direction of the arrow A 3 (see Fig. 7)
until the points of the "needle-beards" are clear past the previously formed row of
loops and the threads which run from the " beam," through the "thread-guide-
troughs" C to the said previously formed row of loops, and this most forward position
of the needles is shown in Fig. 7.
22
During this forward movement of the needles and directly the "needle-beards"
have passed from under the "
presser E the said presser is caused to descend
and press upon and hold down the needle-stems as shown at Fig. 7 and herein after
described. The "thread-guide-bar" C1 (and consequently the troughs" C) is then
moved "shifted ". or "slogged" (as herein after described) across the needles so
that each thread is laid over and partly round the stem of
one needle. The
presser E is then lifted clear of the needles as shown in Fig. 8. The needles
then retire in the direction of the arrow A 2 (see Fig. 8) and in so doing the points
of the "needle-beards " pass over the threads, just laid over the needle-stems. The
presser "E then descends upon and "
presses the needle-beards" as shown in
Fig. 9. 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,
*
.<

page_text: the previously formed row of loops is
landed on the top 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" as shown in Fig. 10. 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. 10) and the "presser "E having risen clear of the needles
the "needle-beards" will pass under the said " presser without being "pressed"
both after the loops are landed" and when the needles again come forward to
receive the next row of loops.
While the last formed row of loops is pulled through the previously formed row of
loops the hooks B are caused to move in the direction of the arrow B3 (see Fig. 10)
and then in the latter portion of their descent they assist in pulling the previously
formed row of loops over the "needle-heads" and then the said hooks hold down and
hold back the previously formed row of loops and the last formed row of loops
(see Fig. 11) while the needles again come forward to receive from the "thread-guide-
troughs" C a fresh row of loops.

The first part of my invention which I will describe consists of the construction
and use of a "
presser "notched or cut or built up with grooves or "tricks" for hooks
to slide or work in, such a "presser" being centered or hinged or otherwise guided
in such a manner that the "pressing-point oľ pressing-edge" of the "presser
can be made to advance and retire to and from the "needle-beards" by a cam or cams
or other suitable means so that the "needle-heards are pressed" at the right time
and place as the needles retire and the "beards are not pressed as the needles come
forward to receive a fresh row of loops.
"
t.
Fig. 6 sheet 6 and Figs. 17 to 21 sheet 9 (in conjunction with others of the
drawings) show this arrangement.
Fig. 6 shows the "Presser" in position in the machine.
Fig. 17 is a part section showing the "presser" and some adjacent parts. Figs. 18
and 19 are part plans of same, Figs. 20 and 21 are part front elevations
of same.
"
E is the movable "presser" notched or cut or built up with grooves or tricks for
the hooks B to slide or work in as shown in the parts of the length of the "presser
marked X Y in Figs. 18 to 21.
"
The said "presser" is provided with two or more arms E1 (Figs. 6, 17 and 19)
which pass through suitable recesses or notches in the main bar F. These arms are
jointed to suitable brackets E 2 (which are attached to the main-bar F) and work upon
the pins or centres E3 so that the " presser "E is free to move upon the pins E 3 in
the direction of the arrows E4, E 5. At the ends of the " presser E suitable
guiding-fingers E6 are provided guided by which the " presser" E slides and thus
the said "presser" E is prevented from moving laterally but is free to advance and
retire to and from the "needle-beards" as actuated by a cam or cans or other suitable
means, so that the "needle-beards" are "pressed" at the right time and place as the
"landed"
needles retire and the "beards" are not "pressed" either after the loops are
or as the needles come forward to receive a fresh row of loops.

guided in such a manner that the "pressing-point" or pressing-edge" of the
presser can 'be made advance and retire to and from the "nec.lle-beards," such
movement being produced by forming upon or attaching to the said presser a number
of "inclines ог "wedge-surfaces," and fitting against these said "inclines
corresponding number of similar inclines" formed upon or attached to a suitable
wedge-bar in such a manner that when the said wedge-bar is moved in the direction
of its length one way by a cam or other suitable means, the "inclines" attached to
the said wedge-bar act upon the "inclines" attached to the "presser in" such a
manner that the presser" is forced down on to the "needle-beards" and they are
thereby pressed" and when the said wedge-bar is moved in the opposite direction the
presser is released and can be lifted so that the "needle-beards are not "pressed."

Figs. 6-17 to 21 sheets 6 and 9 show the arrangement.
وو
33
E is the "presser," as described in the first part of this invention. E 7 are suitable
inclines or inclined-surfaces, formed upon, or attached to the said "presser" E.
ES are similar "inclines," formed upon, or attached to a suitable " presser-wedge-
barE 9. To this said " presser-wedge-bar E 9, motions are imparted in the
directions of the arrows E 10, E 11. (Figs. 20 and 21) by a cam, or other suitable
means. Suitable springs E 12 are attached to the armis E1 of the "
presser" E, by
rods or wires E 13, (Figs. 6 and 17) in such a manner that they pull the " presser E
in the direction of the arrow E5 (Fig. 17). Thus it will be seen that when the
presser-wedge-bar" E9 is moved in the direction of the arrow E 11 (Fig. 21),
the " presser "E will rise, or retire from the "needle-beards" in the direction of the
arrow E 5 (Fig. 17) into the position shown in Fig. 20, and when the said "presser-
wedge-bar is moved in the direction of the arrow E 10 (Fig. 20) the "inclines "E S
on the "
pressure-wedge-bar" E9 will press upon the inclines" E7 on the
<< presser" E in such a manner that the " presser E is caused to advance in the
direction of the arrow E 4 (Fig. 17) into the position shown in Fig. 21 and to "press
the "needle-beards" as and when required.
66
"
"
The third part of my invention which I will describe consists of the construction
and use of a moveable "presser" worked by "inclines" as in the second part of this
invention, its movements being created and governed by a cam or other suitable
means, in such a manner that the "presser" is made to press upon the stems of the
needles and hold them down while the "thread-guides" or thread-guide-troughs"
are moved or "shogged across the needles, and thus there is less danger that a
needle (if it is strained, or bent, or lifted, or displaced) will be further displaced and
injured by the said "thread-guides" or "thread-guide-troughs' as they are
shogged." Then as soon as the "shog" is completed the "presser" is made to rise
to the right height for being ready to "press" the "needle-beards."
<
"
Figs. 6 and 17 to 24, sheets 6, 9 and 10, in combination with other drawings,
show this arrangement. Figs. 22 to 24 are three views of a cam and some adjacent
parts for producing the required motions in the "presser-wedge-bar" E 9 herein before
described. His a cam which is driven by the spur-wheel 1 on the main-shaft D.
H2 is a moveable frame which carries the "bowls" or "trucks" H 3, H 4.
27
Between
these two said "bowls" the cam H revolves. It will be seen that if the parts of
the two faces of the said cam H which work in contact with the two said "bowls" H 3
and H4, be suitably, shaped then as the said cam H revolves it will impart a
reciprocating motion to the frame H 2 in the direction of the arrows H 5, H6; such
motion being governed and determined by the form and position of the said shaped
parts of the said cam H. The said frame H 2 is supported and guided by a suitable
bracket H 7, and is attached to the herein before described "presser-wedge-bar" E9,
so that all motions imparted to the said frame H 2 by the said cam H are transmitted
through the said " presser-wedge-bar" E9, to the said " presser as herein
before described. Thus by suitably shaping the edges of the said cam H, I cause the
presser" E to press upon the needle-stems (as shown in Fig. 7 sheet 7) while the
"thread-guide-troughs are moved or shogged across the needles, and then as
soon as the "shog" is completed, the "presser" is caused to rise to the right height
for being ready to "press" the "needle-beards."
«
33
The fourth part of my invention which I will describe consists of the construction
and use of a supplementary hook-bar (for pulling or forming a fringe, or row of
extra long loops) arranged across the front of the machine and behind the fabric.
The said hook-bar is actuated by a suitable shaft and by racks-and-pinions, chains,
bands, or tapes, or other suitable means, and the hook-bar may be in some cases
balanced by suitable weights or springs, in such a manner that when the said shaft
is turned in one direction, the said hook-bar will rise into such a position that the
hooks are nearly up to the needles and their points touch the fabric. Then when the
said shaft is turned in the opposite direction, the said hooks are caused to hook into
the fabric and then by continuing to turn the said shaft in the same direction a row
of long loops is pulled to any desired length to form a fringe after which the said

page_text: loops are cut in a suitable manner. The said shaft may be turned by a ratchet, ratchet
wheel and lever, or by any other suitable means, or in some cases the motions of the
said hook-bar may be obtained by a rocking shaft and suitable levers or arms.
Figs. 1 to 4 sheets 1 to 4 and Fig. 6 sheet 6 show this arrangement.
Figs. 1 to 4 show the said supplementary hook-bar, which I call a "fringing-bar'
in its position in the machine. Fig. 6 shows a section of the same out of action,
and shows the bar (in dotted lines) in its position when beginning to pull a fringe.
Jis the said "fringing-bar." To this fringing-bar J I attach a row of hooks JJ.
(cast in "leads," or attached to the bar J by any other suitable well known means).
This row of hooks extends the full width of the needles of the machine. J2 is a
roller, or shaft which works in suitable bearings. J 3 is one of several steel tapes, or
bands, or chains, one end of which is fastened to the shaft J 2, at J 4, and the other
end is fastened to the hook-bar J by the tightening screw J. Suitable balance
weights J 6 (Figs. 1 and 2) are attached to the said hook-bar J by cords, or chains J 11,
running over suitable guide-pulleys. J 7 is a shield, cover, lid or guard, which may
turn upon the bearings, or centres J 8. When it is desired to pull a fringe the
shaft J 2 is turned (by a hand-wheel, ratchet and lever, or any other suitable well
known means) in the direction of the arrow J9 when the balance weights J 6 will
cause the hook-bar J to rise behind the fabric into the position shown by dotted lines,
and then the hooks J 1 will touch the fabric, and then if the shaft J 2 be turned in
the direction of the arrow J 10 the hook-bar J will be pulled down by the bands J 3
and the hooks J 1 will look into the fabric and a row, or
"course "of long loops can
be pulled to any length desired; which loops are afterwards cut and so form the fringe.
When the desired length of loops for a fringe has been pulled, if the "fringing-bar" J
and the hooks J1, be slightly lifted the fabric can be easily disengaged or
unhooked from the hooks J1, and then the " fringing-bar" J can be made to
descend into its former position behind the shield J 7, which will fall into its original
position and protect the hooks J 1 and "fringing-bar" J until it is again required.
In some cases instead of attaching the said "fringing bar" to the shaft J by steel
tapes, or bands, as shown, I attach, or connect then by racks and pinions, chains or
cords, or other suitable well known means.
It will be evident that the shaft J 2 may be placed in any convenient position in the
machine other than that shown, and the tapes, bands or chains connecting it with the
fringing-bar" may pass round a suitable guide-bar, or roller, or rollers, in or about
the position of the shaft J 2, and the same motions can thus be produced in the
"fringing-bar."
27
:
The fifth part of my invention which I will describe consists of a method of imparting all
the necessary "shogging" motions to the " thread-guide-bar" which carries the "thread-
guides ог thread-trough-guides" &c., and consequently to the threads or warp
by means of a straight rack, or racks, cast on, attached to, or cut in, the said bar in such a
manner that the teeth in the said rack, or racks, are of the same gauge or "pitch" as the
needles in the machine. Adjacent to this rack, or racks, I arrange two levers, or
combination of levers which

or "pawls" are so arranged that when the lever, or levers to which they
"pawls
ratchets
are attached are inoved in a certain direction, one of the said
will engage with the said rack, or one of the said racks, and cause it or them, and
consequently the bar also, to move a distance of one tooth, or needle. These two
said ratchets or pawls are also so arranged that when the one is moved it
causes the said rack, or racks, and consequently the "thread-guide-bar," with the
threads or "warp," to move or shog in one direction, and when the other
"ratchet or "pawl" is moved it causes the "thread-guide-bar" to move or "shog
in the opposite direction. Thus by moving one or other of the said two levers, or
combinations of levers, the "thread-guide-bar" is "shogged one tooth, or needle, at
a time either to the right or left as desired. Adjacent to the two said levers, or
combination of levers, l'arrange one, or more, suitably shaped cams fixed to the
main shaft (or to an auxiliary shaft of the machine). Between the said levers and
cam, or cams, I interpose a suitable "push-piece" in such a manner that when it is in
::

page_text: one position it connects the said cam or cams with one of the said levers, and when in
the other position it connects the said cam or cams with the other of the said levers.
Thus by shifting the said "push-piece" the direction of the "shog" (or movement of
the thread-guide-bar") is reserved. Upon or connected with the said "thread-
guide-bar," I arrange two suitable adjustable stops in such a manner that when the
said "thread-guide-bar" has "shogged" as many steps in one direction as desired,
one of the said adjustable stops moves (or causes to be moved) the said push-piece
into the position necessary for reversing the "shog." Thus the number of "shogs
to the right and to the left is governed by the said adjustable stops. Figs. 25 to 27
sheet 11 show this arrangement.

plan of same, and Fig. 27 is an elevation of some details hereinafter described.
C1 is the thread-guide-bar." K and K 1 are two racks cast on, attached to, or cut
in the same. The teeth in these said racks being the same "
gauge or pitch" as
the needles in the machine. K 2, K3 are two "ratchets 23
or pawls" which gear
into the said racks K and K 1. K4, K 4 are two short arms or levers which work upon
the fixed centres K 5, K5 and are jointed at the other ends to the "ratchets" or
"pawls" K2, K3. K6, K6 are two spiral springs attached to the ends of the
ratchets K2, K3. K7, K8 are two connecting-rods jointed to the said ratchets K2, K3
(and the arms K4 K 4) and working in suitable guides K 9. It will be seen that if
the connecting-rod K 7 be pushed in the direction of the arrow K 11 the ratchet K 2
will engage with the rack K as shown, and move or "shog" the "thread-guide-bar "C1
in the direction of the arrow K 13. Then when the pressure upon the connecting-
rod K 7 is released the spring K 6 will pull the ratchet back again ready to again be
pushed forward and to again" shog" the "thread-guide-bar" C1. K 14, K 14 are two
pins or stops, so arranged that as the ratchets K 2, K3 are drawn back by the
springs K 6 the said stops cause the said ratchets to lift clear of the said racks K
and K1, so that the ratchet K 2 is free to move the "thread-guide-bar" C1 in the
direction of the arrow K 13, and the ratchet K3 is free to move the said
"thread-guide-bar" C1 in the direction of the arrow K 12 when actuated by the
connecting-rods K 7, K 8. Opposite the ends of the two connecting-
rods K 7, K 8 are two cams K 15, K 16 fixed to the main shaft D. These two
cams are so shaped that they will impart the necessary motions to the said connecting
rods K7, K8 to work the ratchets K2, K3 as before described. K17 K 18, are the two
ends of a "push-piece" which is free to turn on the centre, or pin, K 19. The two
ends K 17 K 18 of the said "push-picco" are connected together by flat springs which
allow either of the two said ends to move in the direction of the arrows K 10, K 11;
either being independent of the other; and the said "push-piece" is arranged to turn
upon the centre K 19, so that when in one position the end K 17, is between the cam K 15
and the connecting rod K 7 and the other end K 18 is free, and when in the other
position, the end K 18 is between the cam K 16 and the connecting rod K 8; and the
other end K 17 is free. Thus when the said "push-piece" is suitably moved upon its
centre K 19 either the end K 17 or K 18 is interposed in its position to rack or "shog" the
"thread-guide-bar" C 1 when required. The said ends K 17, K 18 are made of such a
length and so arranged, that when the end K 17 is interposed between the cam K 15 and
the connecting rod K 7, the ratchet K 2 is set in motion, and when the end K 18 is
interposed between the cam K 16 and the connecting-rod K 8, the ratchet K 3 is set in
motion. Thus by suitably moving the said "push-piece" either the ratchet K 2 or the
ratchet K3 is set in motion at pleasure. K 20 is a lever working upon the centre K 21, one
end of this lever is attached to the said "push-piece" by suitable spring-attachments K 22.
The other end K 23 slides upon a suitably notched or recessed bar K 24 so arranged that
when the end K 23 of the lever K 20 is moved in the direction of the arrow K 12 it slips
into a suitable notch or recess; and then the end K 17 of the "push-piece" is put into
action and the ratchet K 2 is worked. And when the end K 23 of the lever K 20 is
moved in the direction of the arrow K 13, it slips into another suitable noich provided for
it in the bar K 24, and the ratchet K 3 is worked. Upon the "thread-guide-bar "C1 are
two adjustable stops K 25, K 26 arranged and adjusted so as to engage with the

page_text: end K 23 of the lever K 20. It will now be seen that when the ratchet K 2 is in
action the "thread-guide-bar" C1 will be "shogged" in the direction of the
arrow K 13 until the stop K 26 comes in contact with the end K 23 of the
lever K 20, when the said lever will be moved, and the ratchet K 2 will be thrown
out of action, and at the same time the ratchet K 3 will be put in action, and the
motion of the "thread-guide-bar" C1 will be reversed. Thus by adjusting the said
stops K 25, K. 26 the ratchets K 2 and K 3 are automatically set in motion, and the
"thread-guide-bar" (1 is "shogged any number of "shogs to the right, and
then any number of "shogs" to the left, as desired.

The sixth part of my invention which I will describe consists of the construction
and use of a cam, and other adjuncts as hereinafter described, for imparting the
necessary motions to the "thread-guide-bar." This said cam imparts a reciprocating
motion to a suitably-guided rod, so arranged that one end of the said rod engages
with, and is worked by, the said cam, and the other end is forked or opened out so
as to partly embrace a ratchet-wheel, the two ends of the said fork being suitably
shaped so as to form two suitable "ratchets" or pawls," which can be made to engage
with the said ratchet-wheel at, or near opposite sides, the said forked-end being
sufficiently opened so that when the said fork is moved to one side, the one end or
ratchet or pawl" is put into gear and the other is put out of gear and vice-versa.
Upon or connected with the said ratchet-wheel, I arrange two suitable adjustable
stops, so that when one end or "ratchet" or "pawl" of the said forked-rod has rocked
the said ratchet-wheel as many "shogs" as desired in one direction, one of the said
stops moves or causes to be moved the said forked-rod, so that the one end is thrown
out of gear, and the other end is thrown into gear, and so the motion of the said
"ratchet "-wheel, is changed automatically as desired. The said ratchet-wheel may be
connected to the thread-guide-bar" by any convenient means, such as a pinion
working into a rack, or any other well known method.

Figs. 28 to 30 sheets 12 and 13, with others of the drawings, show this arrange-
ment. Fig. 28 is a plan, Fig. 29 is an elevation, of this arrangement with some
adjacent parts, and Fig. 30 is a part plan with the ratchet-wheel L5 removed, and the
axle L 22 and parts of the main-bar F shewn in section. L is the cam referred to.
L1 is a forked-rod or frame, guided at one end by a pin L. 2, so as to be free to slide
"bowl "
on the bracket L3 in the directions of the arrows L9 and L 10. L4 is a
attached to the forked-rod L 1, and engaging with the cam L as shown. It will be
seen that the rod L 1 is forked or widened out at one end, so as to partly embrace the
ratchet-wheel L 5. The two ends of the said forked-rod L 1, are suitably shaped so as
to form two suitable ratchets or "pawls" L6 and L 7, or the said ratchets or "pawls
may be preferably made separate from and attached to the said forked-rod L1, and
adjustable as shown in the drawing. The forked-end or ratchet-end of the rod L1,
rests and slides upon two suitable bearings 1.8. The rod L 1 is caused to reciprocate
in the direction of the arrows L9, L 10 (Figs. 28 and 29) by the cam L. The forked-
end or ratchet-end of the rod L 1 is free to move also in the directions of the
arrows L11, L12 (Fig. 28). The amount of this motion is regulated by suitable
guides L 13, and the spring-bolt, wedge, or guide L 15, in such a manner that when
the rod L1 is moved in the direction of the arrow L 11, the ratchet L7 will engage
with and work the ratchet-wheel L 5, in the direction of the arrow L 21 and when
the rod 1 is moved in the direction of the arrow L 12, the ratchet L 6 will
At the middle
engage with and work the ratchet-wheel L 5 in the opposite direction.
of the ratchet-end of the rod L 1, 1 form a Vee or wedge-shaped surface L 14, and
engaging with this is a spring-bolt L 15, suitably guided and free to move only in the
directions of the arrows L9, L 10. The said bolt L 15 is caused to move in the
direction of the arrow L 10 and kept in contact with the vee-shaped surface L, 14, by
the springs L 16.
As represented in the drawing (Fig. 28) the ratchet end of the rod L1 is in the
position as far as it can go in the direction of the arrow L 11, and the vee-shaped end
of the holt L 15, pressing upon the ver-shaped surface L 14, of the rod L1 (by the
pull of the spring L 16) keeps it in that position until moved. If when the rod L 1 is
B

page_text: in this position it is moved by the cam L in the direction of the arrow L9, the
ratchet L 7 will engage with and move or "shog" the ratchet-wheel L5 in the direc-
tion of the arrow L 21. Upon the ratchet-wheel I5 are two suitable adjustable stops
or fingers L 17, L 18, and upon the rod I are two fixed pins. These stops or
fingers and pins are so arranged and adjusted that they will cause the ratchet-end of
the rod L1 to be moved in the directions of the arrows L 11, 12 and thus throw the
ratchets L6, 7' alternately in and out of gear automatically; and this action is as
follows: If motion be imparted to the rod L1 in the direction of the arrows L9, L.10
while it is in the position shown in the drawing, the ratchet L 7 will rack or "shog
the ratchet-wheel L 5 in the direction of the arrow L 21 until the stop L 17 comes into.
such a position that as the rod L 1' is moved in the direction of the arrow L 10, the
pin L 19, comes in contact with the stop or finger L 17, and the rod L1 is then moved
in the direction of the arrow L 12, so that the point of the vee-shaped surface on the
rod L 1, is pushed past the point of the bolt L 15, by which motion the ratchet L7 is
thrown out of gear and the ratchet 16 is thrown into gear, and the motion of the
ratchet-wheel L5 will be reversed during the next revolution of the main shaft. In
like manner the stop or finger L 18, is adjusted to throw the ratchet L 7 into gear, and
the ratchet L6 out of gear; and thus by adjusting the stops L 17 and L 18 the motion
of the ratchet-wheel L5 can be automatically reversed and re-reversed after any
number of "shogs" have been made. The motions imparted to the ratchet-wheel Lo
can be transmitted to the "thread-guide-bar" CI, and so to the "thread-guide-
troughs", by any well known convenient means. As shown in the drawings, the
ratchet-wheel L5 is attached to shaft or spindle L. 22. To the same spindle is attached
a pinion or segment of a pinion L 23 which gears into a suitable rack upon the
"thread-guide-bar" (1, thus it will be seen that all "shogging" motions imparted to the
ratchet-wheel I5, will be transmitted to the "thread-guide-troughs" and conse-
quently to the threads or "warp" as desired. It will be evident that the amount of
movement of the "thread-guide-troughs" at each "shog or movement of the
"ratchet-wheel "L5, will be regulated by the "pitch" of the teeth of the said "ratchet-
wheel L5 and the amount of motion of the cam L, which are constructed and
regulated to suit the "gauge" of the machine.
The Seventh part of my invention which I will describe consists of the construction
and use (for imparting the necessary motions to the "thread-guide-bar") of a cam or
cams with a push-piece" levers and "ratchets" or "pawls," in a similar manner to
the fifth part of my invention, in combination with a ratchet-wheel or wheels (or
segments of same) into which the said "ratchets " or "pawls "work, the said "ratchet-
>>
wheel or wheels are attached to a suitable shaft.

The said "ratchets or "pawls" being carried by suitable arms working upon the
same shaft as the said "ratchet wheel or wheels, and motion is imparted to the said
arms and "ratchets "

ing-rods, and the said "push-piece which connects one or other of the said connecting
rods with the said cam or cams as governed by suitable stops upon the said "ratchet-
wheel" or wheels. To the shaft which carries the said "ratchet-wheel" or wheels is
also fixed a toothed-wheel or a segment of the same. This toothed-wheel or segment
gears into a rack upon the "thread-guide-bar" and thus each movement of the cam.
or cams is transmitted through the push-piece" levers "ratchets" 01 pawls

guide-bar."

Figs. 31 to 33 sheets 14 and 15 show this arrangement. Fig. 31 is a part elevation
of the arrangement. Fig. 32 is a plan of same and Fig. 33 is a back view of paris
of same. M is a "ratchet-wheel" attached to a shaft M 1. Working upon the said
shaft M 1 (as close to the said "ratchet-wheel as convenient) are two independent
arms or "bell-crank-levers" M 2, M 3-one arm of the "bell-crank lever "M 2 carries
a ratchet or pawl" M4 and the corresponding arm of the "bell-crank-lever" M3
carries a ratchet or " pawl M 5. These two ratchets M 4, M work into the teeth
of the ratchet-wheel "M and are so arranged that when motion is imparted to
either the one or the other of the arms M2, M3 the one ratchet will turn the
..

page_text: "ratchet-wheel" M in one direction and the other ratchet will turn it in the opposite
direction. The ends M6, M7 of the said "bell-crank-levers " M2 M3 are provided
with suitable stops M 8, M 8 and suitable springs M 9, M 9 which are arranged so as
to allow the ends M 6, M 7 of the bell-crank-levers" M 2, M3 sufficient movement
in the direction of the arrows M 10, M 11 to cause the ratchets M4, M5 to rack the
"ratchet-wheel" M one tooth. Two suitable stops M 24, M 24 are provided and so
arranged that when the ratchets M 4, M5 are not in action the said stops M 24, M 24
hold the said ratchets out of contact with the teeth of the "ratchet-wheel" M.
M 12 is a suitable connecting-rod having two forked ends M 13, M 14 which work in
suitable guides M 15, M 15. The said connecting-rod M 12 is free to move in the
direction of the arrows M 10, M 11 and receives motion in the direction of the
arrow M 11 from the cam M 16 and is drawn back in the direction of the
arrow M 10 by the spring M 17. M 18, M 19 are two ends of a suitably arranged
'push-piece" (similar to that described in the fifth part of this invention) which
is free to move on the centre piu M 20 in such a manner that when it is in one
position the end M 18 is interposed between the end M 13 of the connecting-
rod M 12 and the end M 6 of the "bell-crank-lever" M 2, and when in the other
position the end M 19 is interposed between the end M 14 of the connecting-rod M 12
and the end M 7 of the bell-crank-lever" M3. Thus it will be seen that by moving
the said "push-piece" on its centre pin M 20 the connecting-rod M 12 is connected
with the "bell-crank-lever" M 2 or M 3 and the ratchets M4 or M5 are put in and
out of action as desired.
:.
*
To the boss of the said " push-piece sometimes apply a suitable spring M 25
which fits into suitable notches on the said boss in such a manner that it assists
in placing the said "push-piece "in one or other of the two positions described, and
retains the said "push-piece" in either position when so placed.
To the boss" of the said "push-piece" is attached an arm M 21 (Fig. 33) which
may be more or less elastic.
:6
Upon the ratchet-wheel" M are two adjustable stops M 22, M 23 arranged and
adjusted so as to engage with the end of the said arm M 21 in such a manner that as
the ratchet-wheel' Mis racked or << shogged" by the ratchet M-4 any desired.
number of times, the stop M 22 comes in contact with the said arm M 21 and throws
the end M 18 of the "push-piece "out of gear and consequently the end M 19 into
gear and the motion of the ratchet-wheel" M is thus reversed. In like manner the
adjustable stop M 23 reverses the motion of the "ratchet-wheel "M in the opposite
direction when desired. Thus by adjusting the stops M 22, M 23, any desired numbers
of "shogs" of the "ratchet-wheel "M in each direction can be made automatically.
The motions of the "ratchet-wheel " M can be communicated to the "thread-guide-
bar "C1 by similar means to that described in the sixth part of this invention, or by
any other suitable well known means.
"
The Eighth part of my invention which I will describe consists of the construction
and use of a cam or cams for imparting the necessary motions to the "thread-guide-
bar" suitably connected to two arms or levers each of which carries a "ratchet" or
pawl." The two said "ratchets or "pawls" work into a suitable "ratchet-wheel "
or wheels (or segments of same) at or near the opposite sides, in such a manner that
one "ratchet
or "pawl" will turn the "ratchet-wheel" or wheels in one direction
and the other "ratchet" or "pawl" in the other direction.
Between the said
"
"
"
".
< ratchets or "pawls" and the "ratchet-wheel" or wheels I
interpose a moveable shield or "stop-piece" in such a manner that when moved in
one direction it lifts the one ratchet or pawl out of gear, and lets the other
into gear and when moved in the opposite direction the acting "ratchet "or "pawl"
becomes idle and what was the idle ratchet
**
or "pawl" becomes the acting ratchet
or is thrown into gear.
""
"
Thus by moving the interposed shield or stop-piece the motion of the said " ratchet-
wheel" or wheels is reversed. The said "ratchet-wheel" or wheels inay transmit its
or their motion to the thread-guide-bar" by any convenient means such as a rack

page_text: and a pinion or two steel tapes or chains fastened to the trough-bar and to theopposite
sides of a pulley attached to the said "ratchet-wheel" or wheels.
The above named moveable shield or stop may be moved as required for changing
the direction of motion of the said "ratchet-wheel" or wheels (and consequently the
"shog" of the "trough-bar") by suitable adjustable stops attached to or connected with
the said "ratchet-wheel" or wheels in such a manner that the said adjustable stops
automatically govern the number of " shogs " of the "thread-guide-bar" to the
right and left.
Figs. 34 and 35 sheet 16 show this arrangement Fig. 34 is an elevation of the
arrangement and Fig. 35 is a plan of sanie. N is a "ratchet-wheel "attached to a
shaft N 1, similar to that described in the seventh part of this invention.
Working freely upon the said shaft N 1 are two arms or levers N 2 and N 3 which
carry two ratchets or
"pawls" N4 and N 5. The two said ratchets are arranged to
act upon the "ratchet-wheel" N in such a manner that the ratchet N4, when in
action, will turn or rack the "ratchet-wheel " N in one direction, and the ratchet N 5
will, when in action, turn the said ratchet-wheel N in the opposite direction. N 6 is
a cam fixed upon the main-shaft D. The ends of the two arms or levers N 2 and N 3
are kept in contact with the cam N 6 by the spring N 7 as shown. The part of the
said cam N 6 in contact with the said arms N2, N3 is suitably shaped so as to
impart motion to the two said arms N 2, N 3 in the direction of the arrows N 8
and N 9. N 10 is a moveable arm free to turn upon the shaft N 1. This arm carries
a shield or disengaging-piece N 11 at its end, so arranged that the said shield passes
down in front of the teeth of the said "ratchet-wheel.' It will be seen that if the
said shield be turned upon the shaft N 1 in the direction of the arrow N 8 it will
lift the ratchet N 5 out of contact with the teeth of the said "ratchet-wheel" N
and let the ratchet N 4 go into action and thus it will rack or "shog" the "ratchet-
wheel" N in the direction of the arrow N 9. Then if the said shield be turned
upon the shaft N1 in the direction of the arrow N 9, it will lift the ratchet N 4
out of action and let the ratchet N 5 go into action.
Upon the "ratchet-wheel" N are two adjustable stops N 12 and N 13 so arranged
and adjusted that as the "ratchet-wheel" N is moved round one or other of the said
stops N 12 or N 13. (depending upon the direction in which the said "ratchet-wheel"
is moving) will come into contact with the arm N 10 of the shield N 11. It will be
seen that as the "ratchet-wheel" N is moved round by the ratchet N 4 in the direction
of the arrow N 9, the stop N 12 will come into contact with the arm N 10 and shift
the said shield in such a manner that it will lift the "ratchet" N 4 out of action
and drop the ratchet N 5 into action and will reverse the motion of the "ratchet-
wheel" N. In a similar manner the stop N 13 shifts the shield N 11 and in so doing
lifts the ratchet N 5 out of action and drops the ratchet N 4 into action. Thus by
adjusting the two stops N 12 and N 13 the racking or "shogging" motions of the
"ratchet-wheel" N are automatically reversed and re-reversed after any desired
numbers of "shogs" have been completed. N 14 is a suitable spring arranged to
work into two suitable Vee-shaped notches in the end of the arm N 10 as shown,
and so adjusted that when it is in one notch the shield is in the right position for
one ratchet to be in action, and when in the other notch it is in the right position
for the other ratchet to be in action. Thus the spring N 14 holds the shield N 11 in
its right position until moved by one or other of the said stops N 12 or N 13.
The "shogging" motions of the "ratchet-wheel" N may be transmitted to the
"thread-guide-bar" C1 by a pinion or segment on the shaft N1 working into
a rack
upon the
thread-guide-bar" C1 as described in the sixth part of this
invention or by any other of the suitable well known means such as steel tapes or
chains.
ود.
The ninth part of my invention which I will describe consists of the construction
and use (in combination with the apparatus for "shogging" the "thread-guide-bar
as referred to in parts 5 to 8 of this invention) of a chain, or of a suitably equally
divided strap or band moved in such a manner that it advances regularly one or

page_text: more or less links or divisions for each revolution of the machine. Upon this
chain, strap, or band, I arrange suitable inclines" and in such a manner that they
engage with suitable levers and govern the order of the "shogging" or to and fro
movements of the "thread-guide-bar."
"
"
It will be evident that by suitably arranging the positions of the said "inclines"
upon the said chain, strap, or band, many variations of "shogs or movements of
the "thread-guide-bar" in either direction may be made, and consequently many
variations of patterns of work can be made automatically without stopping the
machine.
Figs. 36 to 38 sheets 17 and 18 show this arrangement. Fig. 36 is an elevation of
the arrangement. Fig. 37 is part plan of same and Fig. 38 is a section through
part of same as indicated.
P is a suitably divided chain or band, but I prefer to use what is properly known in
France as Chaine Vancanson" (or better known among makers of Knitting
machinery as Paget's chain") a portion of which is shown full size in Figs. 39
to 41 as adapted to this apparatus.
"
$
"
The said endless chain i' slides on a suitable "chain-guide" P 1, attached to a
convenient part of the machine. P 2 is a ratchet attached to the "ratchet-ro: " P 3.
The end or point of the said ratchet P2 passes through a suitable slot in the "chain-
guide" P 1 so that the chisel-shaped point or upper end of P 2 enters between and
acts upon the links or bars of the said chain P so as to draw it forward link by
link in the direction shewn by the arrows P 8 and P 19. P4 is a cam fixed to the
main-shaft D. P5 is a "Bowl" or "Truck or roller upon the end of the "ratchet-
rod" P3. This "bowl" P5 works upon the cam P4. A suitable spring P6 is
attached to the "ratchet-rod" P3 and keeps the "bowl" P 5 in contact with the cam P 4.
This cam (with the spring P 6) imparts motion to the ratchet P2 in the direction of
the arrows P7, P8 which motion enables the ratchet P2 to propet the chain P
forward in the direction of the arrow P 8 one link or bar for each revolution of the
main-shaft D. A suitable spring-retaining-ratchet" P9 is provided to prevent
the chain P from slipping back. Upon the chain P suitable "inclines" P 10
and P 11 are arranged in two rows, one row near each side of the chain. P 12 and
P 13 are two rocking-shafts. On these rocking-shafts are levers or arms P 14
and P 15 so arranged that one end of each is stopped by the stop P 16. The other
ends of these levers or arms are suitably shaped (and come directly over the two
rows of "inclines" P10 and P 11 on the chain P) in such a manner that as the
chain P is propelled forward by the ratchet P 2 one or other of the said inclines,
may at certain times lift one or other of the said levers and thus create a small
angular motion in one or other of the two rocking-shafts P 12 or P 13. Upon the
other ends of the said rocking-shafts P 12 and P 13 are fixed two arms or levers P 17
and P 18. It will be seen that as the chain Padvances and one of the "inclines" P 10
comes under the lever P 15 the lever P 18 is lifted, and when one of the
"inclines" P 11 comes under the lever P 14 the lever P 17 is lifted. R is a frame
working in suitable guides R 1 and R 2 and carrying a "bowl" or
" truck "> R 3.
This frame R is caused to move in the direction of the arrows R4 and R 5 by a
suitably shaped cam R6 which is fixed to the main shaft D. Two springs R 7 keep
the bowl 3 in contact with the cam R 6. The rod R has two "inclines or wedge-
shaped surfaces formed upon it at R 8 and R 9. R 10 is a connecting-rod working in
suitable guides and free to move in the direction of the arrows R 11 and R 12 and
passing just beneath the "inclines" R8 and R9 on the rod R. R 13 and R 14 are
suitable.stops, fingers or lugs" upon the said connecting-rod R 10.
23
23
R 15 and R 16 are suitably shaped "push-pieces" hanging from the levers P 17.
and P 18 by the rods R 17 and R 18. R 19 are suitable springs attached to the
bottom ends of the said rods R 17 and R 18. The said push-pieces R 15
and R 16 are so shaped and arranged and adjusted that when the lever P 17 is lifted
by one of the "inclines" P 11 as before described, the "push-piece" R 15 is lifted
(when the frame R and consequently the "incline "R8 is at its furtherest position in
the direction of the arrow R 5) into such a position see Fig. 38 that it is in contact

page_text: with the incline RS and the stop R 13. Then as the cam R 6 moves the frame R in
in the direction of the arrow R 4 the "incline" R8 moves the connecting-roll R 10
in the direction of the arrow R 12. In like manner when the push-piece" RTG is
lifted by the lever P 18 the incline R 9 moves the connecting-rod R 10 in the direction
of the arrow R 11. Thus it will be seen that when one of the "inclines" P 10 lifts
the end of the lever. P 15 the connecting-rod R 10 is moved in the direction of the
arrow R11 and when one of the "inclines "P 11 lifts the end of the lever P 14 the
connecting-rod R 10 is moved in the direction of the arrow R 12. Thus by suitably
arranging inclines" on the chain P the connecting-rod R. 10 can be made to move in
the direction of the arrows R 11 or R 12 automatically at any desired intervals of
any desired numbers of revolutions of the machine (and consequently any desired
numbers of the courses or rows of the fabric) have been made.
"
If the end R 20 of the connecting-rod R 10 be jointed to the "push-piece" K 17
and 18 in a suitable manner, Figs. 25 and 26 sheet 11 (described in the fifth part of
this invention) and the two stops K 25 and K 26 be taken out of action; then the
motions of the said connecting-rod R 10 will work the said "push-piece" and thus
the said "inclines" on the said chain P will govern the "shogging" motions of
the thread-guide-bar" C1 as herein beforo described.
K
In like manner if the end R 20 of the connecting-rod R 10 be suitably jointed to
the rod 1. Figs. 28 to 30 sheets 12 and 13 (described in the sixth part of this
invention) at a suitable point, such as L 14, and if the two fingers L 17 and L 18
be thrown out of action, then the two ratchets L6 and L7 will be thrown in and
out of action by the said "inclines" on the said chain P and the "thread-guide-
bar"C1 will be "shogged "as herein before described.
In like manner if the end R 20 of the connecting-rod R 10 be suitably jointed to
the end of the arm M 21 Figs. 31 to 33 sheets 14 and 15 (described in the seventh
part of this invention) and the stops M 22 and M 23 be taken out of action the
motions of the " push-piece and consequently the motions of the "thread-guide-
bar 1 will be governed by the said "inclines" on the said chain P as herein-
before described.
לי
"
In like manner if the end R 20 of the connecting-rod R 10 be suitably jointed to
the arm N 10, which carries the shield N 11, Figs. 34 and 35 sheet 16 (described in
the eighth part of this invention) and the stops M 12 and M13 be taken out of
action, the motions of the said shield N 11 and consequently the motions of the
thread-guide-bar" C 1 will be governed by the said "inclines" on the said
chain P as herein before described.
It will be evident that instead of using a chain, such as herein before described
and shown at Figs. 39 to 41 sheet 18, for carrying the "inclines" which impart
motion to the levers P 14 and P 15, a strap, tape, or band, may be used which may
have suitable projections upon it, or suitable holes in it, at suitable intervals apart
and arranged in such a manner that the said projections or holes will enable the
ratchet P2 to propel the said strap tape or band forward and some of the said
projections or holes will impart the necessary movements to the levers P 14
and P 15.
- Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I desire it to be under-
.stood that I do not confine myself to the exact details herein set forth as such may
be varied and 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 :-
"
"6
First. The construction and use of a r presser "notched or cut or built up with
grooves or tricks" for books to slide or work in, such a presser being centred or
hinged or otherwise guided in such a manner that the pressing-point or pressing-
edge of the "presser can be made to advance and retire to and from the "needle
beards" by a cam or cams or other suitable means, so that the "needle-beards"
are "pressed" at the right time and place as the needles retire and the "beards" are
לי

page_text: not pressed as the needles come forward to receive a fresh row of loops, substantially
as herein before described with reference to Figs. 6 and 17 to 21 sheets 6 and 9.
"

*
Second. The construction and use of a presser" plain or notched or cut or
built up with grooves or tricks for hooks to slide or work in, such a presser. being
centred or hinged or otherwise guided in such a manner that the "pressing
point, or prossing" edge of the " presser can be made to advance and retire to
and from the "needle-beards" such movement being produced by forming upon or
attaching to the said "presser a number of "inclines or wedge-surfaces" and
fitting against these said "inclines" are a corresponding number of similar
"inclines" formed upon or attached to a suitable wedge-bar. in such a manner that
when the said wedge-bar is moved in the direction of its length one way, by a cam or
other suitable means, the. " inclines" attached to the said wedge-bar act upon the
"inclines" attached to the "presser" in such a manner that the "
presser" is forced
down onto the needle beards" and they are thereby "pressed" and when the said
wedge-bar is moved in the opposite direction the " presser is released and can be
lifted so that the "needle-beards" are not "pressed" substantially as hereinbefore
described with reference to Figs. 6 and 17 to 21 sheets 6 and 9.
Third. The construction and use of a moveable "presser" worked by "inclines"
as in the second part of this invention, its inovements being created and governed by
a cam or other suitable means in such a manner that the "
presser "is made to
or
"
press" upon the stems of the needles and hold them down while the "thread-guides
thread-guide-troughs" are moved or "shogged" across the needles and thus
there is less danger that a needle (if it is strained or bent or lifted or displaced) will
be further displaced and injured by the said "thread-guides" or "thread-guide-
troughs" as they are "shogged." Then as soon as the "shog" is completed the
presser" is made to rise to the right height for being ready to "press" the "needle-
beards substantially as hereinbefore described with reference to Figs. 6 and 17
to 24 sheets 6-9 and 10.
"
Fourth. The construction and use of a supplementary book-bar (for pulling or
forming a fringe or row of extra long loops) arranged across the front of the machine
and behind the fabric. The said hook-bar is actuated by a suitable shaft and by
racks-and-pinions, chains, bands, or tapes or other suitable means and the hook bar
may be in some cases balanced by suitable weights or springs in such a manner that
when the said shaft is turned in one direction the said hook-bar will rise into such
a position that the hooks are nearly up to the needles and their points touch the
fabric. Then when the said shaft is turned in the opposite direction the said hooks
are caused to hook into the fabric and then by continuing to turn the said shaft in
the same direction a row of long loops is pulled to any desired length to form a
fringe, after which the said loops are cut in a suitable manner. The said shaft may
be turned by a ratchet, ratchet wheel and lever, or by any other suitable means, or
in some cases the motions of the said hook-bar may be obtained by a rocking-shaft
and suitable levers or arms, substantially as herein before descrit ed with reference to
Figs. 1 to 4 sheets 1 to 4 and Fig. 6 sheet 6.
.:
Fifth. The method of imparting all the necessary shogging motions to the thread-
guide-bar which carries the " thread-guides" or thread-trough-guides" &c. and
consequently to the threads or warp by means of a straight rack or racks cast, on
attached to, or cut in, the said bar in such a manne: that the teeth in the said rack
or racks are of the same 'guage" or "pitch" as the needles in the machine.
Adjacent to this rack or racks I arrange two levers or combination of levers which
carry two ratchets" or "pawls." These two " ratchets" or "pawls" are so arranged that
when the lever or levers to which they are attached are moved in a certain direction, one of
the said "atches" or "pawls" will engage with the said rack or one of the said racks, and
cause it or them, and consequently the bar also, to move a distance of one tooth or
needle. These two said ratchets " or "pawls" are also so arranged that when the
one is moved it causes the said rack or racks, and consequently the " thread-guide-
bar" with the threads or "warp," to move or shog in one direction, and when
the other ratchet" or pawl" is moved it causes the "thread-guide-bar" to move

page_text: "
or "shog" in the opposite direction. Thus by moving one or other of the said iwo
levers or combinations of levers the "thread-guide-bar" is "shogged" one tooth or
needle at a time either to the right or left as desired. Adjacent to the two said levers
or combination of levers I arrange one or more suitably shaped cams fixed to the
main shaft (or to an auxiliary shaft of the machine). Between the said levers and
cam or cams I interpose a suitable "push-piece" in such a manner that when it is
in one position, it connects the said cam or cams with one of the said levers, and
when in the other position, it connects the said cam or cams with the other of the
said levers. Thus by shifting the said "push-piece" the direction of the ". shog
(or movement of the "thread-guide-bar") is reversed. Upon or connected with
the said "
thread-guide-bar" I arrange two suitable adjustable stops, in such
a manner that when the said "thread-guide-bar has "shogged
as many steps
in one direction as desired, one of the said adjustable stops moves (or causes to be
moved) the said push piece into the position necessary for reversing the "shog."
Thus the number of "shogs" to the right and to the left is governed by the said
adjustable stops; substantially as herein before described with reference to Figs. 25
to 27 sheet 11.
22
Sixth. The construction and use of a cam and other adjuncts as herein before
described for imparting the necessary motions to the "thread-guide-bar." This said
cam imparts a reciprocating motion to a suitably guided rod, so arranged that one
end of the said rod engages with and is worked by the said cam, and the other end
is forked or opened out so as to partly embrace a ratchet-wheel, the two ends of the
said fork being suitably shaped so as to form two suitable " ratchets or pawls"
which can be made to engage with the said ratchet-wheel at or near opposite sides,
thesaid forked end being sufficiently opened so that when the said fork is moved to one
side the one end or "
33
ratchet or "pawl" is put into gear and the other is put out
of gear and vice-versa. Upon or connected with the said ratchet wheel I arrange two
suitable adjustable stops so that when one end or
"ratchet or "pawl" of the
said forked rod has racked the said ratchet wheel as many "shogs" as desired in one
direction, one of the said stops moves or causes to be moved the said forked-rod so
that the one end is thrown out of gear and the other end is thrown into gear, and
so the motion of the said ratchet-wheel is changed automatically as desired. The
said "ratchet-wheel" may be connected to the "thread-guide-bar" by any convenient
means such as a pinion working into a rack, or any other well known method;
substantially as herein before described with reference to Figs. 28 to 30 sheets 12
and 13.

Seventh. The construction and use (for imparting the necessary motions to the
thread-guide-bar") of a cam or cams with a "push-piece" "levers
33 and "ratchets "
or "pawls" in a similar manner to the fifth part of niy invention in combination with
a ratchet wheel or wheels (or segments of same) into which the said "ratchets " or
pawls" work, the said "ratchet-wheel" or wheels are attached to a suitable shaft.
The said ratchets
"
or "pawls" being carried by suitable arms working upon the
same shaft as the said "ratchet "-wheel or wheels and motion is imparted to the said
arms and ratchets
«
or pawls" by the said cam ог cams through suitable
connecting rods, and the said "push-piece" which connects one or other of the said
connecting rods with the said cam or cams as governed by suitable stops upon the
said "ratchet" wheel or wheels. To the shaft which carries the said "ratchet-
wheel" or wheels is also fixed a toothed-wheel or a segment of the same. This
toothed-wheel or segment gears into a rack upon the "thread-guide-bar" and thus each
movement of the cam or cams is transmitted through the said "push-piece" levers
ratchets pawls" "ratchet-wheel" or wheels and toothed wheel or segment
and rack to the said "thread-guide-bar"; substantially as herein before described
with reference to Figs. 31 to 33 sheets 14 and 15.
<

or
**
Eighth. The construction and use of a cam or cams for imparting the necessary
motions to the "thread-guide-bar" suitably connected to two arms or levers each of
which carries a "ratchet" or "pawl." The two said " ratchets or pawls" work
into a suitable "ratchet "-wheel or wheels (or segments of same) at or near the opposite
د"
"

page_text: 22
"
"
sides in such a manner that one "ratchet or "pawl" will turn the "ratchet-wheel "
or wheels in one direction and the other "ratchet " "
or pawl" in the other direction.
Between the said "ratchets " or "pawls and the "ratchet-wheel or wheels 1
interpose a moveable shield or stop-piece in such a manner that when moved in one
direction it lifts the one 66 ratchet" ог "pawl" out of gear and lets the other into
gear, and when moved in the opposite direction the acting "ratchet " or "pawl"
becomes idle and what was the idle "ratchet' or "pawl" becomes the acting
ratchet or is thrown into gear. Thus by moving the interposed shield or stop piece
the motion of the said "ratchet "-wheel or wheels is reversed.
The said "ratchet "-wheel or wheels may be transmit its or their motion to the
"thread-guide-bar" by any convenient means, such as a rack and a pinion or two
steel tapes, or chains fastened to the "trough-bar" and to the opposite sides of a
pulley attached to the said "ratchet" wheel or wheels.
وو
The above named moveable shield or stop may be moved as required for changing
the direction of motion of the said "ratchet "-wheel or wheels (and consequently
the "shog
of the "trough-bar") by suitable adjustable stops attached to or
connected with the "ratchet"-wheel or wheels in such a manner that the said
adjustable stops automatically govern the number of "shogs" of the "thread-guide-
bar to the right and left substantially; as herein before described with reference to
Figs. 34 and 35 sheet 16.
"
"
Ninth. The construction and use (in combination with the apparatus for "shogging"
the "thread-guide-bar" as referred to in parts 5 to 8 of this invention) of a chain
or of a suitably equally divided strap or band moved in such a manner that it
advances regularly one or more or less links or divisions for each revolution of the
machine.
Upon this chain, strap or band I arrange suitable "inclines" and in such a manner
that they engage with suitable levers and govern the order of the "shogging'
to and fro movements of the "thread-guide-bar."
"
or
It will be evident that by suitably arranging the positions of the said "inclines"
upon the said chain strap, or band, many variations of "shogs" or movements of the
thread-guide-bar" in either direction may be made and consequently many variations
of patterns of work can be made automatically without stopping the machine;
substantially as herein before described with reference to Figs. 36 to 41 sheets 17
and 18.
