IMPROVEMENTS IN STRAIGHT KNITTING-MACHINES
Year: 1884

page_text: I, ERNEST DE PASS, of 68 Fleet Street, in the City of London, Fellow of the
Institute of Patent Agents, do hereby declare the nature of said invention for
IMPROVEMENTS IN STRAIGHT KNITTING-MACHINES, communicated to me from abroad
by La Société Verdier, Moreau, et Compagnie, of 5 rue du Conservatoire, Paris,
France, to be as follows:-
This Invention relates to certain improvements applicable to the manufacture of
various kinds of knitted goods, and more especially to stockings which, by way of
example, I proceed to describe.
The said improvements relate chiefly to the production of fancy knitted goods
in several colours, and to the production of strengthened knitted articles, whether
on a stripe on the axis of the web, and upon the whole, or a portion of this stripe,
or upon the parts of the said web situated to the right and left of the said stripe,
and upon the whole or a portion of the said parts.
In one method of manufacturing a stocking according to this Invention, a stripe
on the axis, and of any suitable width, occupies the whole length of the web; this
stripe is in one colour, whilst the parts on the right and left of the said stripe are
of another colour.
In a second method, the stripe on the axis only occupies a suitable portion of
the length, and at its ends diminishes in the form of a series of steps; it is of one
colour, whilst the remaining portion of the web is of another colour. The steps
may be more or less pronounced, and may, if desired, be merely in the form of
almost straight oblique lines.
"
In a third method, the portion of the stripe on the axis (analogous to that just
described). is strengthened relatively to the remainder of the web surrounding it,
which gives a stocking strengthened at the knee. To obtain this strengthening
it is sufficient to 'take, not as hereinabove described, yarns of different colours-
but yarns of different thicknesses, the thickest being that which forms that part of
the stripe situated on the axis. The knees of drawers, the elbows of under vests,
tights, etc. etc. may also be strengthened in this way.
In a fourth method, the strengthening is effected on the parts situated to the
right and left of, the stripe on the axis, in such manner, that the toe, the sole and

page_text: "
the heel of the stocking (this latter to as great a height as may be desirable) are
strengthened, that is to say, formed by thicker yarn, whilst the remaining portion
of the web, and especially the portion of the stripe on the axis corresponding to
the instep is not strengthened.
In another method the strengthening is effected by means of the difference in the
thickness of the yarns, in the same way as described in the fourth' method, except,
that for the part of the sole corresponding to the hollow of the foot, that is to say,
for a part of the sole less brought into action than the other parts.
These indications given, the number of which might be multiplied, shew that
fancy goods in several colours and the strengthened goods previously referred to,
may be thus produced, by means of these improvements, by the juxtaposition of
yarns of different colours or sizes. By means also of these improvements such
strengthened goods may also be produced by the superposition of the yarns.
The machine to which these improvements are supposed to be applied is a'
Dutch-machine of the known type, consequently provided with a saddle having
two driving legs: On the frame of this machine are fixed suitable supports for the
purpose of supporting on the front of the said machine, an added mechanism,
or mechanism differing from that of the so called Dutch-machine, this being also
provided with its saddle having two driving legs.
To the saddle of the Dutch-machine is added a second saddle, this latter being
provided with an arm, by the aid of which, and by screws the two saddles are
firmly connected together and united by a common connection are-taken as a
whole-hereinafter termed the "double saddle."
In the Dutch-machine, the chief parts consist of the saddle, the left-hand slur,
the left yarn-holder carrier, the heeler, the right yarn-holder carrier, the right slur,
the counter, (wheel for the pitch-chain with its ratchet wheel and the tooth of the
counter).
c
The added mechanism which is superposed on the Dutch-machine cousists,
amongst other parts, of the saddle, à left hand slur, a single yarn-holder carrier, a
right-hand slur, supports fixed to the frame of the Dutch-machine and supporting
the whole of the added mechanism, except one bar whose special supports are fixed
on the curved parts of the Dutch-machine. The supports of both the Dutch-
inachine and the added mechanism admit of horizontal development as may be
required, either to the right or left; the same of course holds goods as regards the
various parts connected to these supports.
.
The heeler of the Dutch-machine is made so as to be moveable, that is to say, so
that it may be placed on the corresponding bar, or be removed therefrom, as
desired; this, as will hereinafter be seen is indispensable for the working of the
whole of the improved mechanism in question; this operation is, moreover, assisted
and regulated by various flat or spiral springs.
For the production of fancy goods in different colours, let it be supposed that
the motion is communicated from the left to right to the double saddle, the left
hand slur of the added mechanism first raises the driving leg on the right of the
added saddle in such manner that this leg seizes the yarn-holder carrier of the
added mechanism at the desired point and carries along this carrier until the said
.leg encounters the right hand slur which, at the same time arrests the said carrier.
and causes the said leg of the saddle to escape. If the motion be communicated
from the right to left, the left driving leg of the added saddle acts in the same
way in reverse order relatively to the same slurs. On these slurs are mounted
sliding parts; these sliding parts which are in the form of an angular bracket may
be fixed by means of pressure screws in different positions on the corresponding
slurs, and so, as to bring into or out of action, as may be desired, articulated pawls
with which these, slurs are provided. These pawls, take into teeth formed in the
two ends and on the top and bottom faces of a rack bar supported in the bottom
ends of the supports on the Dutch-machine, relatively to which its position may be
regulated by means of screws, the pressure screws serving to maintain it fixed in
tlie, desired position. The articulated pawls, of both the added slurs have joint.

page_text: pins, which project on the inner side and are operated by two grooved rods, held
at their ends by S-shaped pieces, which pieces are jointed to the ends of two
balance or oscillating levers fixed on a horizontal shaft, supported in bearings
provided on the supports fixed to the Dutch-machine; at its right hand end this
shaft is fitted with a hand-lever by means of which a movement of oscillation may
be communicated to the balance levers, the effect of which is to cause the grooved
rods to move away from or draw nearer to each other. The hand lever may, if
desired, be operated by means of a counter with pitch chain, or by means of any
other auxiliary mechanism of the same kind an example of which is hereinafter
given.
.
The pawls carry projecting parts terminating in horizontal pins, which, when the
sliding parts are caused to advance sufficiently, travel up slightly inclined planes,
in which the said sliding parts terminate (at the same time raising the corresponding
pawls) until these pins engage in semi-circular recesses formed in the ends of the
sliding parts. The pawls, of which the pins are thus engaged, are drawn away
sufficiently from the teeth of the rack that they may no longer engage therein. If
it be desired to widen the stripe on the axis, then. the upper pawls are thrown out
of action in the manner just indicated, and inversely, the lower pawls are left free:
to act, in order that, by reason of the motion communicated by means of the hand
lever to the grooved rod, the slurs, of the added mechanism, shall draw away from
one another. If, on the contrary, it be desired to narrow the stripe on the axis,:
the lower pawis of said mechanism are thrown out of action, leaving the upper
pawls free to act, and the movements of the grooved rod will cause the slurs to
draw towards each other. Behind these slurs are jointed cranked pieces whose ends
fall into the working space of the Dutch-machine, and there serve as slurs for the
driving legs of the saddle of the said machine; these parts may, if desired, be turned
down, and therefore no longer intervene in the working space of the Dutch
machine. The added carrier is so arranged as to operate, or not, as may be desired,;
at the same time as the carriers of the Dutch-machine, or the one or the other of
these carriers may operate. For this purpose, a pressure screw is kept screwed up,
or unscrewed, which allows of the end of the carrier being pivotted, and of its
being turned down. During the time the stripe on the axis is not being made the.
added carrier, the cranked pieces and the carrier of the Dutch machine are put out.
of action for entering the stocking only, in order to make a passage for the carrier
of the Dutch-machine, which alone operates in the said entering; it is when this
carrier thus works alone that the heeler of the Dutch machine is placed in the said
entering of the stocking to allow of escape being made. The bar, hereinbefore
mentioned connected to the corresponding bar of the Dutch machine by the special
supports, serves to lift the tube holder of the carrier of the added mechanism;
a bar fixed by its ends on the supports supporting the whole of the added
mechanism, keeps the head of the added saddle in movement, not bearing too
heavily on the saddle, and preventing injurious play.
The preceding indications suffice to explain how, by means of the double saddle,
and of the three carriers employed singly or in combination, fancy knitted goods in
several colours, or strengthened, may be produced by the juxtaposition of yarns of
different colours and sizes, by employing, 1, a first yarn which works into the whole
width of the stocking: 2, a second yarn which produces the strengthening by
becoming superposed on the first, and which, to this end, only works on the part of
the stripe on the axis, or on the parts situated to the right and left of the said
stripe which it is proposed to strengthien.
In order to obtain, by super-position of the yarns, the stocking strengthened at
the kuce, as before mentioned, the cranked pieces are turned down, the heeler of
the Dutch-machine is placed in its usual position on the right where it will escape,
and thus all the operations herein before indicated for entering the stocking will be
repeated except that the added carrier will be left working which will consequently
work on the part of the web that has to be strengthened at the same that the
carrier of the Dutch machine will work over the whole of the width of the said

page_text: web. To obtain. likewise, by superposition of the yarns, stockings strengthened as
described in the 4th and 5th methods, the added carrier is caused to work over the
whole width of the web, and for this purpose the added slurs are put back suitable
distances towards the left and right hands; the Dutch-machine is then arranged as
for making the heel, that is to say, with its heeler placed in the middle of the rack
bar of the said machine, and its slurs so arranged in position that the right and left
yarn holders of its carriers fall into selvage exactly at the same points between the
needles as the yarn holder of the carrier of the added mechanism: that is to say, in
such manner that the carrier of the Dutch-machine falls at the same point as the
added carrier at the left extremity of the web, and that the carrier of the Dutch
machine falls at the same point as the added carrier at the right hand extremity of
the web.
+
To effect diminishing, the two following methods may be adopted-1st The
slurs of the added mechanism having been made to correspond exactly with the
slurs of the Dutch-machine, these slurs are placed two by two in firm connection
with each other so as to form two groups, and that by means of the rigid connecting
stays; whose ends are screwed on to the said slurs; these stays are placed in the
same direction and serve the same purpose with regard to the slurs (that of
a common connection) as the legs (of the added saddle) with regard to the double
saddle. Then spiral springs are unhooked-one end of each of these being con-
nected respectively to the added slurs, the other end keeping engaged the pawls,
which serve for widening the web-in such manner that the said pawls are
disengaged from the teeth of the rack corresponding thereto. In this way these
slurs are, upon each diminution, readily placed in suitable position by the action of
the machine itself. 2nd, The second method of diminishing, consists in removing the
cranked pieces and substituting other pieces also connected to the rear face of the
added slurs; these pieces project like the cranked pieces above mentioned into
the working space of the Dutch machine, and terminate on the side of this machine
in escaping surfaces of the same form as the corresponding ones of the added slurs,
in such manner that they serve the same purpose with regard to the saddle of the
Dutch-machine as the added slurs, with regard to the added saddle. Then the end
of the handle of the tooth of the counter is connected by a rod either to the end
of the hand lever, or to that of a lever fixed like the hand lever, on a suitable
part of the shaft.

page_text: COMPLETE SPECIFICATION.
I, ERNEST DE PASS, of 68 Fleet Street in the City of London, Fellow of the
Institute of Patent Agents, do hereby declare the nature of said invention for
IMPROVEMENTS IN STRAIGHT KNITTING MACHINES, communicated to me from abroad
by La Société Verdier, Moreau et Compagnie, of 5 rue du Conservatoire, Paris,
France, and in what manner the same is to be performed, to be particularly
described and ascertained in and by the following statement, reference being had
to the accompanying drawings, and to the letters and figures marked thereon, that
is to say
This Invention relates to certain improvements applicable to the manufacture of
various kinds of knitted goods and more especially to that of stockings, which, by
way of example, is taken in the following description.
The said improvements relate chiefly to the production of fancy knitted goods in
several colours, and they also allow of the production of strengthened knitted
articles; whether on a stripe on the axis of the web and upon the whole or a
portion of this stripe, or upon the parts of the said web situated to the right and
left of the said stripe, and upon the whole or a portion of the said parts..
Figs. 1, 2, 3, 4 and 5 (which represent stockings opened out) will give a general
and sufficient idea of the results that may be obtained, although the number of
possible combinations for each of the kuitted articles in question is of course
infinite, as will be readily understood on perusal of the present description. In
these figures the parts hatched at different inclinations, or cross lined, differ from
each other either in colour or in the strengthening.
Thus, in the stocking represented in Fig. 1, a stripe on the axis x, x, of any
width, capable of being varied at will, occupies the whole length of the web; this
stripe is of one colour whilst the parts on the right and left of the said stripe are
of another colour, according as to whether these two last mentioned portions are to
be, or not, of the same colour, thus fancy articles in two or three colours could be
produced.
In the stocking represented in Fig. 2, the stripe on the axis x, x, only occupies a
suitable portion of the length, and at its ends diminishes in the form of a series of
steps of variable number; it is of one colour, whilst the remaining portion of the.
web which surrounds it is of another colour. (The steps referred to may be more
or less pronounced and may if desired be merely in the form of almost straight
oblique lines).
In the stocking represented in Fig. 3, the portion of the stripe on the axis x, x,
(analogous to that of Fig. 2) is strengthened relatively to the remainder of the web
surrounding it which gives a stocking strengthened at the knee. To obtain this
strengthening it is sufficient to take-not as hereinabove described, yarns of'
different colours-but yarns of different thicknesses, the thickest being that which.
forms that part of the stripe situated on the axis x, x. It must of course be
understood that the knees of drawers, tights, the elbows of under vests, etc., may
also be strengthened in this way.
In the stocking represented in Fig. 4, the strengthening is effected on the parts.
situated to the right and left of the stripe on the axis x, x, in such manner that'
•

page_text: 4
the toe, the sole, and the keel of the stocking (this latter to as great a height as
may be desirable) are strengthened, that is to say, formed by thicker yarn, whilst
the remaining portion of the web, and especially the portion of the stripe on the
axis corresponding to the instep or upper part of the foot, is not strengthened..
In the stocking represented in Fig. 5, strengthening by means of difference in
the thickness of the yarns is effected in the same way as for the stocking repre-
sented in Fig. 4, except for the part of the sole corresponding to the hollow of the
foot, that is to say, for a part of the sole less brought into action than the other
parts.
These indications given, with the aid of some examples, the number of which
might easily, but without any very great advantage, be multiplied, shew that fancy
goods in several colours, and the strengthened goods previously referred to, may be
thus produced by means of these improvements by the juxtaposition of yarns of
different colours, or of sizes. By means also of these improvements such strengthened
goods may also be produced by superposing the yarns.
The machine to which these improvements are supposed to be applied is a Dutch
machine of the known type, consequently provided with a saddle furnished with
two driving legs. On the frame of the machine are fixed supports of a special
form, for the purpose of supporting on the front of the said machine, an inserted
mechanism or additional mechanism distinct from that of the so called Dutch
machine, this additional mechanism being also provided with its saddle having two
driving legs.
In the description hereinafter given of the figures of the annexed drawings, the
capital letters designate parts constituting the so called Dutch machine and the
small letters the parts constituting the additional mechanism. In all these figures
similar letters of reference indicate like parts.
Fig. 6, is a perspective view of the saddle A, of the Dutch machine, and of the
saddle a, of the additional mechanism, this latter a, being provided with an arm a¹,
by the aid of which and by three screws engaged at first in the holes a², then into
the corresponding holes of the saddle A, the two saddles are firmly connected
together, and thus united by a common connection are-taken as a hole-herein-
after termed the double saddle A, a.
Fig. 7 is a partial elevation of the Dutch machine and of its chief parts, amongst
which are indicated the saddle A,-the left slur B, with jointed pawl-the left
yarn holder carrier C-the heeler D-the right yarn holder carrier E-the right
slur F, with jointed pawl-the bar G serving to raise the tube holders of the
carriers C, E the rack bar J-the grooved bar K-and the counter P, (wheel for
pitch chain with its ratchet wheel and tooth of the counter).
Fig. 8 is a side view of these last mentioned parts.
Fig. 9 is an elevation of the additional mechanism which is superposed on the
Dutch machine hereinabove referred to. For the purpose of greater clearness, in
this figure the bar G of the Dutch machine has been omitted, its supports H, I,
being shewn in section. Amongst the parts of the additional mechanism are
indicated:—the saddle a, connected by means of the arm a¹, and the screws a³, to
the saddle A; the left slur b, with jointed pawls; the yarn holder carrier c; the,
right slut with jointed pawls; the supports d, e, fixed on the frame of the Dutch
machine and supporting all the additional mechanism (excepting however the bar g
which serves to raise the tube holder of the carrier c, the special supports h, i, of
which are, for the purpose in view, fixed on the curved parts of the supports H, I,
of the analogous bar Ĝ of the Dutch machine). It will be further observed that
the supports d, e, h, i, are shewn in this figure and in figure 10 (to be hereinafter
referred to) as capable of being adjusted horizontally to the right or left any
desired extent; the same of course holds good with respect to the parts connected
with these supports.
Fig. 10, is a part sectional plan corresponding to Fig. 9, the section being taken
through the broken line 1, 2, 3, 4 of Fig. 9.
"
Fio 11 is a partial end elevation corresponding to Fio 9.
.:

page_text: Fig. 12 is a general sectional elevation through line 5, 6 of Fig: 9. In this
figure the following parts of the Dutch machine are indicated:-at Ŏ the needles;
at P* the upper plates; at Q* the lower plates. At R R³, the yarns passing to the
carriers are shewn in dotted lines.
Fig. 13, is a part sectional elevation also taken through line 5, 6 of Fig. 9, and
Fig. 14 is a sectional plan through line 7-8 of Fig. 13.
Figs. 13 and 14 have more particularly for object to represent in detail the yarn
holder carrier c.
Figs. 15 and 16 are respectively a front view and a side view of the heeler D,
made removeable, that is to say, so that it may, when desired, be placed on the
bar J, or be removed from this bar, which is indispensable, as will hereinafter be
seen for the working of the improved mechanism in question. This working is
moreover assisted and regulated by the action of various flat and spiral springs.
For the production of fancy goods in different colours, the motion being supposed
to have been communicated from the left to the right to the double saddle A, a, the
slur b, first raises the driving leg on the right of the added saddle a, in such manner
that this leg seizes the carrier c, at the desired point and carries along this carrier c,
until the said leg encounters the slur f, which at the same time arrests the said
carrier c, and causes the said leg of the saddle a, to escape. In the contrary case,
the motion being supposed to have been communicated from the right to the left,
the driving leg on the left of the saddle a, acts in the same way, but in reverse
order relatively to the same slurs f and b. On these slurs are mounted sliding
pieces 61, 62, for the slur b, and f and f³, for the slur f; these sliding pieces which
are in the form of an angular bracket may be fixed by means of thumb screws
61*, *f*, f** in different positions on the corresponding slurs b, f, and so as
to bring into or out of action, as may be desired, the jointed pawls with which
these slurs are provided, viz. 63, 64, for the slur b, and f³, f*, for the slur f. These
pawls take into teeth formed in the two ends and on the top and bottom
faces of the rack bar j,. supported in the bottom ends of the supports d, e,
relatively to which its position may be regulated, by means of screws,, the thumb
screws d, e¹, serving to maintain it fixed in the desired position. The jointed
pawls b³, b, f,f4, of the slurs b, f, have joint pins bs, be, ƒ³, fe, which project on
the inner side and are operated by two grooved bars k, l, held at their ends by
S-shaped pieces k¹, k², 11, 12; these S-shaped pieces are jointed to the ends of two
balance or oscillating levers m', m³, fixed on a horizontal shaft m which is supported
in the bearings d², d³, e², e³, provided on the supports d, e; at its right hand end
this shaft m, is fitted with a hand lever m², by means of which a movement of
oscillation may be communicated to the balance levers m³, m³, which movement
has for effect to move away from or draw nearer to each other, the grooved
bars k, l, The lever mt, which is here taken to be operated by hand, may be
equally well operated by means of a counter with pitch chain, or by means of
any other auxiliary mechanism of the same kind, an example of which is herein-
after given.
The pawls 63, 64, ƒ³, f' carry projecting parts terminating in horizontal pins
67, 68, f, f, which pins ascend (at the same time raising the corresponding pawls)
along the slightly curved inclined planes in which the sliding pieces 61,62, f', ƒ³,
terminate, when the said sliding parts are caused to advance sufficiently to the
right or to the left, this going on until the said pins become engaged in the semi-
circular recesses provided at the ends of the sliding pieces.
The pawls of which the pins are thus engaged, draw away sufficiently from the
teeth of the rack j, that they may no longer engage therein. This being under-
stood, let it be supposed that it be desired to widen the stripe on the axis, then the
upper pawls b³, c³, are put out of action in the manner just indicated, and on the
contrary, the lower pawls b', f', are left free to act, in order that, by reason of
the motion communicated by means of the hand lever m', to the grooved bar l,
the slurs b, f, shall draw away from one another. If, on the contrary, it be desired
to narrow the stripe on the axis, the lower pawls b, f*, are thrown out of action,"

page_text: leaving the upper pawls b³, f³, in action, or free to act, and the movements of the
grooved bar k, will cause the slurs b; f, to draw towards each other. Behind these
slurs b, f, (see Figs. 10 and 13) are jointed the pieces 6º, f; the ends of which fall
into the working space of the Dutch machine and may there serve as slurs for the
driving legs of the saddle A; these pieces may if desired, be brought down in
the direction of the arrows, and consequently no longer intervene in the working
space of the Dutch machine. It may be observed that the carrier c, is fitted up so
as to operate or not, as may be desired, at the same time as the carriers of the
Dutch machine, or one or the other of these carriers. For this purpose (see Figs. 13
and 14) it suffices to keep a thumb-screw c¹, screwed up, or to unscrew the same
which allows of the end of the carrier being pivoted, and of its being brought
down in the direction of the arrow to the position shewn in dotted lines. During
the time the stripe on the axis is not being made, the carrier c, the piece 6º, the
carrier E, and the piece fº, are put out of action for entering the stocking, for
example, in order to inake a passage for the carrier C, which operates by itself in
the said entering; it is when this carrier C, thus works by itself that the heeler D,
is placed in position to allow of escape being made. The bar n, fixed by its ends
on the supports d, e, has only for object to guide and retain the head of the saddle a
in its movement, not bearing too, heavily on the saddle A and preventing injurious
play.
The preceding indications suffice to explain how, by means of the double
saddle A, a, and of the three carriers C, E, c, employed singly, or in combination,
there may be produced by the juxtaposition of yarns of different colours, or of
different thicknesses, fancy goods in several colours, or strengthened in the manner
of those shewn in figs. 1, 2, 3, 4 and 5.
I will now indicate how these improvements in knitting machines allow of the
production by superposition of the yarns of strengthened knitted articles like those
represented in figs. 3, 4 and 5, by employing: 1. A first yarn which works into
the whole width of the stocking: 2, a second yarn which produces the strengthening
by becoming superposed on the first and which, for this purpose, only works on the
part of the stripe on the axis, or on the parts situated to the right and left of said
stripe which it is proposed to strengthen.
In order to obtain, by superposition of the yarns, the stocking strengthened at
the knee, as shewn in Fig. 3, the pieces 6º, f, are let down, the heeler D, is placed
in its usual position on the right where it will effect escape, and thus all the opera-
tions hereinabove indicated for entering the stocking will be repeated except that
the carrier c, will be left working at and during the desired time which will conse-
quently work on the part of the web that has to be strengthened at the same time
that the carrier C, will work over the whole of the width of the said web: To
obtain likewise by superposition of the yarns stockings strengthened as shewn in
Figs. 4 and 5, the carrier c is caused to work over the whole width of the web and
for this purpose the slurs b, f, are put back suitable distances towards the left:
and right; the Dutch machine is then arranged as for inaking the heel, that is to
say, with the heeler D placed in the middle of the rack J; of, the said machine,
and the slurs B, F, of the said machine are so arranged in position that the right
and left yarn holders of the carriers C, E, fall into selvage exactly at the same
points between the needles as the yarn holder of the carrier c; that is to say, in
such manner that the carrier C falls at the same point as the carrier c, at the left
extremity of the web, and that the carrier E, falls at the same point as the carrier c;
at the right hand extremity of the web.
To effect diminishing the two following methods may be adopted: -1. The
slurs b, f, having been brought to correspond exactly with the slurs B, F; these
slurs are placed two by two in firm connection with each other so as to form two
groups b, B, f, F, this connection being effected by means of rigid connecting pieces,
the ends of which are screwed on to the said slurs; these connecting pieces are.
placed in the same direction and serve the same purpose with regard to the slurs
(that of a common connection) as the arm a), with regard to the saddles A, a.

page_text: Then the spiral springs 610, f10, (one end of which is connected respectively to the
slurs b, f, the other end keeping engaged the pawls b', f, which serve for widening
the web) are unhooked in such manner that the said pawls are disengaged from the
teeth of the corresponding rack j. In this way these slurs b, f, are upon each
diminution, readily placed in suitable position by the action of the Dutch machine
itself. 2. The second method of diminishing consists in removing the pieces bº, ƒº,
and substituting other pieces also connected to the rear face of the slurs b, f, but
are only capable of falling in a direction contrary to that of the pieces bº, ƒª;
these new pieces project into the working space of the Dutch machine like
those b, f, and terminate on the side of this machine in escaping surfaces of
the same form as those of b, f, in such manner that they serve the same purpose
with regard to the saddle A, as the slurs b, f, with regard to the saddle a. Then
the end of the handle Q, of the tooth of the counter P, is connected by a connecting
rod either to the end of the hand lever m*, or to that of a lever fixed like this hand
lever, on a suitable part of the shaft m.
Having thus described the invention and the means for practically carrying it
out, as communicated to me by my foreign correspondent, such invention relating
to the production of fancy knitted articles in various colours by the juxtaposition
of yarns, as also knitted articles strengthened by the juxtaposition or super-
position of yarns, I declare that what I claim is
The employment in combination with a Dutch, or other straight knitting
machine, of an additional mechanisın carried by the frame of the straight knitting
machine and composing as its principal parts:-a saddle-a jointed thread carrier
holder-two slurs with jointed upper and lower pawls, provided with means
allowing the said pawls being, when desired, placed in or out of action, and with
parts capable, when desired, of effecting escape into the working space of the
straight knitting machine, a rack bar provided with teeth on its upper and lower
faces-two grooved bars connected together operating the jointed pawls of the
slurs aforesaid, either direct by hand or by an intermediate counter, pitch chain
or other accessory organs of this kind,-the saddle of the additional mechanism and
the saddle of the straight knitting machine being in firm connection the one with
the other, as also the lifting bars of the tube holders of the carrier of the additional
mechanism and of the two carriers of the straight knitting machine; the slurs
of the additional mechanism being moreover capable, in certain cases, of being
connected to the slurs of the straight knitting machine, as also may the special
mechanism of the counter of the straight knitting machine be connected to the
special mechanism for driving the grooved bars of the additional mechanism, all
substantially as herein described and as illustrated in the accompanying drawings.
