I, CHARLES Henry Aldridge, of Pinfold Gate, Loughborough, in the County
of Leicester, Hosiery Machinist, do hereby declare the nature of this invention to
be as follows:-
In the Specification of a former Patent granted to W. Cotton No. 6088 in the
year 1882 was described an automatic machine for making with one set of narrowing
points brought into action in two successive narrowing courses two rows of parallel
narrowings at a distance apart from one another so as to produce stockings or socks
with what is known as the French foot.
In this class of machine two screw boxes were used for making the parallel rows
of narrowings one. mounted on the top of the other a wheel or plate was also
provided for controlling the distance between the two rows and for controlling the
making of what is known as the "peak" where the narrowings are brought together
to a point.
· According to this invention instead of mounting the one screw box on the top of
the other so that the top one is shifted by the movement of the lower one I place
them side by side or in other convenient position so as to be independent one of the
other.
The traverse of the thread layer rod I control by the slide of the main or
ordinary screw box-the traverse of the point rad I control by a slide which can be
moved backwards and forwards by the movement of a lever or cam mounted on the
slide of the additional screw box.
When making the two rows of parallel narrowings at each side of the French
foot the thread layer rod is at the first of the two successive narrowing courses
racked inwards a distance of two needles by the slide of the main box thus at once
placing the thread carrier in proper position over the jack sinker ready for the next
course of work so doing away with an additional motion which had to be given to
the "snapping" for taking up the extra thread caused by the double dip of the
points.
The whole set of points are by the rocking of the lever or cam set inwards so as
all to be brought into position to take loops from the needles.
When the points have descended and taken the loops they are racked forward one
needle by the slide of the additional screw box and then place the loops again on
the needles. At the second narrowing course-the cam or lever is rocked into
a position to allow the slide which carries the stop for the point rod to be drawn
back to a stop on the slide of the additional screw box so that when the points
descend fewer of them take loops from the needles. When they have taken their
loops the slide of this screw box is racked forwards one needle and the points again
place the loops on to the needles-afterwards the slide is racked back a distance of
one needle so that when a double narrowing has again to be made there will be one

box is at the end of the second of the narrowing courses racked back a distance of
two needles instead of one and that the slide which carries the stop for the point rod

COMPLETE SPECIFICATION.
Improvements in Straight Bar Knitting Machines.
I, CHARLES HENRY ALDRIDGE, of Pinfold Gate, Loughborough, in the
County of Leicester, Hosiery Machinist, 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 :-
In the Specification of a former Patent granted to Wm. Cotton, No. 6088, in
the year 1882, was described an automatic machine for making with one set of
narrowing points brought into action in two successive narrowing courses two rows
of parallel narrowings at a distance apart from one another so as to produce
stockings or socks with what is known as the "French foot."
In this class of machine two screw boxes were used for making the parallel rows
of narrowings, one mounted on the top of the other, a wheel or plate was also
provided for controlling the distance between the two rows and for controlling
the making of what is known as the "peak" where the narrowings are brought
together to a point.
According to this invention instead of mounting the one screw box on the top
of the other so that the top one is shifted by the movement of the lower one,
place them side by side, or, in other convenient position so as to be independent one
of the other.
The traverse of the thread layer rod I control by the slide of the main or
ordinary screw box. The traverse of the point rod I control by a slide which can
be moved backwards and forwards by the movement of a lever or cam mounted on
the slide of the additional screw box.
When making the two rows of parallel narrowings at each side of the "French
foot" the thread layer rod is at the first of the two successive narrowing courses
racked inwards a distance of two needles by the slide of the main box thus at once
placing the thread carrier in proper position over the jack sinker ready for the
next course of work so doing away with an additional motion which had to be given
to the "snapping" for taking up the extra thread caused by the double dip of the
points.
The whole set of points are, by the rocking of the lever or cam, set inwards,
so as all to be brought into position to take loops from the needles.
When the points have descended and taken the loops they are racked forward

page_text: one needle by the slide of the additional screw box and then place the loops again
on the needles.
At the second narrowing course-the cam or lever is rocked into a position to
allow the slide which carries the stop for the point rod to be drawn back to a stop
on the slide of the additional screw box so that when the points descend, fewer of
them take loops from the needles.
When they have taken their loops the slide of this screw box is racked forwards
one needle and the points again place the loops on to the needles-afterwards the
slide is racked back a distance of one needle so that when a double narrowing has
again to be made there will be fewer of the points come into action and this goes
on so long as the two rows of narrowings are being made parallel with one
another.
When the two rows of narrowings are to be brought together, so as to meet at a
point, the same movements are repeated except that the slide of the additional
screw box is at the end of the second of the narrowing courses racked back a
distance of two needles instead of one and that the slide which carries the stop for
the point rod instead of being allowed to be drawn back to the stop on the slide
of the additional screw box comes back against a stop on the slide of the main
screw box and other mechanism is employed for shifting the point inwards a
distance of one needle when they have taken their loops, thus the cam or lever
gradually acts less and less upon the slide which carries the point rod stop until
the two rows of narrowings meet together.
Mechanism constructed as above described can by adjusting the stops be readily
adapted for making either ordinary narrowings or what are known as "crow's
feet" narrowings either at the selvedge or in the centre of other pieces of work.
This arrangement will be better understood by referring to Figures 1 to 3,
Sheets 1 to 3, attached hereto.
In these drawings only such parts are shown as are actually necessary for the
proper understanding of the mechanism described, so as to avoid confusion. The
other parts and details are such as are in constant use and well known in straight
bar knitting machines.
Figure is a part end elevation of the mechanism, Figure 2 is a part back view
of the same and Figure 3 is a part plan of the same.
-
A is the screw of the main screw box, A' is its fixed slide bed or bracket which
is. attached to the end standard, or framing of the machine. B is the screw of the
second screw box. B' is its fixed slide bed which may be attached to the fixed
bed, or bracket, A¹ by suitable brackets B³ (Figure 1). The main screw A is
racked by the clawker A working into the rack wheel A². The said clawker A³
is worked in the usual manner by the cam A (on the main shaft X) acting upon
the "truck" A which is attached to the racking arm or lever A. The second
screw B is racked in one direction by the clawker B which is jointed to the
racking arm A and acts upon the rack-wheel B2 and in the opposite direction by
the clawker C which acts upon the rack-wheel C'. The said clawker Cis jointed
to the upper end of the lever C which lever works, or rocks upon the axle C³ and
is actuated by cams C and C' as herein after described. A suitable slight friction
(spring-washer or other convenient arrangement) may be applied between the
lever C and its axle C³ so that the lever C will remain in any position in which
it may be placed by the cams C₁ and Co.
The nut, or screw-box, A' (of the main screw A) carries. the stop bracket.D.
This bracket is provided with a suitable stop screw D₁ to stop or govern, the
traverse of the thread layer rod D³.
Working in the fixed slide bed B₁ there is a moving slide B to which the nut,
or screw box of the screw B is attached. Thus by racking or turning the screw 13
the slide B is racked, or moved. Upon the said slide B is fixed an axle B' which
carries a cam, or-cam-lever B. The said cam-lever B' is connected to the lever C
by the rod B. E is a second moving slide which also works in the fixed slide B'.
Fixed to the slide E is an axle E' (Figures 2 and 3) which carries a truck," or

page_text: "
roller, E. The said truck E' works upon the end of the cam B. A suitable
tension spring E³ is connected to the two moving slides B and E in such a
manner that the slide E is drawn towards the slide B and the truck E' is
thereby brought into contact with the cam B'. Thus when the lever C is moved
by the cam the slide E will be drawn (by the spring E) towards the slide B',
and when the lever C² is moved by the cam C. the slide E will be moved by the
cam B away from the slide B'. The slide E carries an upright" or bracket E
upon each side of this bracket are the "majors or collars E which are fast upon
the narrowing point rod E. Thus the movements of the slide E are com-
municated to the point rod E and consequently to the narrowing points attached
thereto.
"

Attached to the slide E is a bracket-E' (Figures 2 and 3). This bracket carries
an adjusting screw E which is arranged so as to come against the bottom end of
the bolt D in the stop bracket D, at such times and in such a manner as herein
after described. The bottom end of the said bolt D³ is made shape so as to
pass-through-the bracket D, -and-the-1 nose D of the bolt-D (Figure 3) then.
projects beyond the outside face of the bracket D as shown in Figure 3. The
said bolt D lies in a vertical groove in the bracket D and is held in its place by
a suitable spring D and pin D as seen in dotted lines in Figure 1 in some cases
may
also be made to lift out of action. Its lower end is free to receive a small
swinging, or rocking movement in the direction of the arrow D³ (Figure 3).
it
Upon the stop D is an axle D' which carries a lever D°. The end D* of the
lever D is suitably shaped and arranged so that when the end D of the lever D'
is lowered it comes into contact with the nose D' of the bolt D³ (Figures 1 and 3)
and pushes the lower end of the bolt D³ inwards in the direction of the arrow.
D'
(Figure 3).
To the other end of the said lever D is connected a rod, or link, D' the lower
end of which embraces, and is free to slide upon,.a rod D. The said rod D is
carried by a bracket D₁ which is attached to, or part of, one end of a lever D¹².
This lever D works upon the rod, or shaft, F, (Figures 1 and 2). The lower
end of the said lever D is provided with a truck D³ which is actuated by the
cam D14
Now it will be seen that when the gauge screw Es of the slide E (Figures, 2
and 3) is in contact with the bolt Is the cam D will produce a movement (through
the lever D1, the link D' and the lever D) in the slide E, and consequently in the
point rod E' and the narrowing points also.
Jointed to the outer end of the rod D10 (or to other convenient position on the
bracket D or lever D") is a rod Co the top end of which is suitably connected to
the clawker C and is so adjusted that when the cam D moves the lever D³, the
clawker C is lifted out of contact with the rack wheel C¹ thus leaving the screw B
free to be racked by the clawker B*.
A short shaft, or axle, G (Figures 1 and 2) is carried by a suitable bracket from
the fixed slide A'.. Fast upon the said shaft G there are two arms G¹ and G.
The arm G has an axle, or pin, G³, and the arm G2 has an axle, or pin, G.
The said arms G' and G' are so arranged that when the lever C is moved by the
cam C³, it comes into contact with the axle G³, and moves the arm G and
consequently the arm G³ also. The axle Gis thus pressed against the clawker A
and holds it out of contact with the rack wheel A2 so that while the lever
remains in its forward position (as placed by the cam C) the screw A is not racked.
In order to better understand the action of the several parts of the mechanism
herein before described we will take the case of making a "French-foot" and note
the action of the several parts seriatim.
The diagramn Figure 4, Sheet 4, shows roughly the formation or the position and
direction of narrowings in the toe part of a "French-foot."
Let the dotted lines a b and c d represent the two rows of parallel narrowings at
each side of the foot, and from bd to e, the "peak." The number of points in the
narrowings fingers are sufficient to cover all the needles from the selvedge to the

page_text: inner narrowing c; and the narrowing machine. goes down twice in succession and
66 narrows" during two consecutive revolutions of the main shaft.
At the first of the two successive narrowing courses the cam B' is in the position
shown in Figure 3, so that the whole set of points are in position to take loops
from the needles from f to c, Figure 4. When the points have taken the loops
they are racked in one needle by the clawker B*. At the same time the main
screw A is racked by the clawker A' so that the slide stop D and consequently the
carrier rod D is racked in a distance of two needles, thus at once placing the
thread carriers in the correct position over the "jack-sinkers" ready for laying
the next course of work.
The points then place the loops back on to the needles i.e. they complete their
first "one-needle-narrowing." As soon as the first narrowing is completed the
cam C moves the lever C; by this movement the clawker A8 is thrown out of
action (as herein before described) and the cam B7 (Figure 3) is turned upon its
axle B and the spring E pulls the slide E (and consequently the narrowing points
also) back to the stop screw E (Figure 3) in the slide B. The points now descend
again and this time take fewer loops from the needles (i.e. f to a, Figure 4). When
they have taken these loops they are racked in one needle by the clawker B and
they then place the loops on the needles again and so complete their second "one-
needle-narrowing." When the second narrowing is completed and the main
shaft X is shogged back into its normal position, the cam C acts upon the levér (2
which is thereby placed in the position shown in Figure 1 and the cam B' moves
the points inwards ready for the next double narrowing. By this last movement of
the lever C2 the clawker C engages with the rack wheel C on the screw B and
racks it (and consequently the slides B and E and the points also) back, or out, a
distance of one needle, so that when the next double narrowing is made there will
be one loop less taken off the needles. These movements are repeated all down the
parallel narrowings from a c to b d (Figure 4). During this time the screw box A'
will have moved forward a distance of two. needles for each double narrowing
whilst the slide B' will have moved forward one only. The screw box A' will
therefore overtake the slides B and E and by the time bd (see Figure 8) is
reached the stop D' will have been brought into position for Es to come back
against it. The two rows of narrowings have now to be brought together so as to
form the "peak "bd to e (Figure 4). To do this the same movements are repeated
except that the slide B (Figure 3) is (at the end of the second of the two successive
narrowing courses) racked back by the clawker C a distance of two needles instead
of one so that at the end of two consecutive narrowings it will have returned to
the same position as when these two narrowings commenced and the slide E instead
of being stopped by the stop screw E on the slide B³ (Figure 3) when the first
narrowing is completed, it is stopped by the gauge screw E coming into contact
with the bolt D'. When the points take their loops for the second narrowing with
the slide E stopped by the bolt D³ the racking of the slide B will not shift the
points, as the slide E is not then in contact with the slide B; but here the cam D
moves the lever De (on the stop bracket D) whereby the lower end of the bolt Da
is moved inwards.(as hereinbefore described) and the slide E and consequently the
points: also are moved, or racked, one needle and thus the second successive
narrowing is completed. In this way as the screw box A is at each double
narrowing advancing two needles whilst B is advanced and then returns to its
former position the truck E² on slide E is acted upon less and less by the cam B7
until at last B' ceases to act upon it altogether. At this point the two rows of
narrowings will have been brought together and the peak is complete.
The clawker C is caused to rack the slide B back one needle when forming
the parallel narrowings and two needles when forming the "peak" in the following
manner :-
:
On the main screw-box or nut A' is a bracket H to which is attached an
adjustable strip H. This strip can be adjusted endwise by means of a screw and
nut in a slot as shown..

page_text: Projecting below the clawker C is an incline C7 Figures 1 and 2. During the
formation of the parallel narrowings the strip H' will be in such a position that
the incline C will slide upon it. By these means as the clawker C is drawn back
by the lever the incline C will prevent it from dropping into the tooth
immediately below, but will permit it to drop into the second tooth. The. rack.
wheel C is then racked only one tooth, or needle.
When the main screw box A7 has been racked in as far as the part where it is
desired to start the peak, the strip H' is so adjusted that the incline C on the clawker C
will no longer touch it. The clawker C then drops into the tooth immediately
below it and the rack wheel C¹ is then racked two teeth, or needles, back instead
of one.
When it is desired to make plain, or ordinary narrowings the clawker_B* may be
thrown out of action by any convenient means and the slide E may be coupled
direct to the screw box A' by a bolt, or other convenient attachment, not shown.
By these means the main screw A only is in action when on plain work.
It will be observed that the foregoing description has dealt with the mechanism
at only one end of the knitting machine, but it will be readily understood that the
mechanism at the other end of the machine is practically the same.
In some cases where a "split foot," "split toe" or what is known as a "three
quarter toe "with cross stitch is required carry the stops and catches for con-
trolling the traverse of the thread layer rods upon a slide which can be shifted
end wise to and fro a short distance along the top of the slide of a screw box which
extends preferably over the top of the slur bar. The end wise movement is given
to the top slide at each course whilst the bottom by which it is carried. is racked
inwards from time to time in conjunction with the slides of the other screw boxes
used for forming the narrowings. In this way the making of a "split foot" "split
toe or "three quarter toe
with cross stitch can be continued at the same time
that these parts are being shaped by the making of narrowings.

Figures 5 to 7 Sheet 4 show this arrangement-Figure 5 is a part end view of
the mechanism-Figure 6 is a part back view of the same, and Figure 7 is a part
plan of the same.
J is the end of the "slur bar." Upon this "slur bar" is a slide or saddle K.
Below the said bar J is a screw K' which is carried in suitable bearings K' K².
The said screw K' works in a nut or screw box K3 which is attached to the saddle K.
On the outer end of the screw is a rack wheel K which is worked, or racked, by
the clawker K (Figure 5). The said clawker K³ can be conveniently jointed to
the racking lever A Figure 1 and is so arranged that as the ordinary narrowing
slides are racked in, the saddle K is racked in also. In the top of the saddle K is
a slide K to which is attached a bracket K' for supporting the bolt stop K³.
The carrier rod N passes through the said bracket K. On the end of the
carrier rod N is a suitable stop piece K. D is part of the slide stop on the screw
box A shown in Figures 1 to 3 and D' D' are stop screws for the ends of the
carrier rods M and N. It will be seen that the bolt K carries a stop screw K1
which is placed in such a position that when the bolt is down as shown the
screw K10 will catch the stop piece K on the rod N. Thus the rod N is stopped
in one direction by the stop screw D₁ and in the other direction by the stop
-screw K10. In the end of the slide K and at right angles to it is a horizontal
bolt M' having a stop screw M² which stops the carrier rod M when the bolt M'
is in the position shown.
When the stop screw M³ is not required the said bolt M1 may be moved forward
so that the stop screw M will be out of the way and the rod M will then be
stopped by the selvedge stop D'.
At the lower end of the bracket K' there are two lugs or projections K" K"
Figures 6 and 7, on the saddle K are two other lugs carrying the stop screws K.K¹4
against which the lugs K" K" strike and by which the amount of movement of
the top slide K is governed. In a vertical slide at the back of the saddle K is a
bolt L. The lower end of this bolt L embraces a rod or crank pin L' which is

page_text: carried by an arm L' on the shaft L³. A rocking motion is imparted to the
shaft L by a suitable cam placed at any convenient part of the main shaft. Thus
by the motion of the said cam a vertical movement is imparted to the bolt L. The
top of the said bolt L passes between the two lugs K" K" and is so shaped with
incline surfaces (as seen in Figure 6) that when it rises it presses upon the
lugs K" or K" and shifts them (and consequently the stop screw K10 and M² also).
from the stop screws K" or K" a distance of two needles into the central position.
as shown in Figure 6 and holds them in this central position.
In some cases instead of racking the slide K by a separate screw K' the slide K
niay be connected to the main screw box A' by a bolt or other convenient means so-
that when the screw box A' is racked the slide K will be racked with it..
"
In order to better understand the mechanism above described we will consider
its motions when in action. Let the diagram Figure 8 Sheet 4 represent part of a
"split-foot" and let the parts marked with parallel lines represent the parts or
sides made of one sort of yarn, and let the plain part of the diagram represent the
part made of another sort of yarn. Let the edge marked , represent the left..
hand selvedge as the work comes off the machine and the right hand selvedge
and let and y represent the lines of cross stitch.
I
=
It should here be observed that the mechanism shown in Figures 5 to 7 represents.
the right hand or No. 2 end mechanism. The left hand or No. 1 end mechanism is.
precisely the same with the exception that the bolt K is applied to the middle.
carrier rod D2 instead of to the back rod N as shown.
Three carrier rods are used in making the "split foot." The carriers on the.
front rod M lay the thread for the centre portion to y Figure 8. The carriers.
on the back rod N lay the thread on the right hand (when looked at from front of
inachine) or No. 2 side ie. y to: Figure 8. And the carriers on the middle rod D
lay the thread on the left hand or No. 1 side i.e. e to x. Their movements are as
follows:-
First we will note the motion of the front carrier rod M. The thread carrier
will start from Figure 8 the slide M' having first been pushed in to bring stop M
into action and slide K³ pushed down to bring the stop screw K10 into action and
will lay a thread to y where it is stopped by the stop screw M². The bolt L will
then be up as shown in Figure 6 and holding the slide K' in its central position.
When the sinkers are retiring ready for drawing the next course and the needles
are descending to knock over the work the bolt L is lowered and the friction on the
carrier rod M the draw bar not having completed its motion causes it to press on the
stop screw M2 whereby the slide K is moved until the projection K" upon it comes.
The carrier rod M is then in its

correct position to start its return course i.e. one "lead" beyond where it finished
its last course. On completing this return course it will be stopped and regulated
by the corresponding stop and mechanism at the other end of the machine.
Now we will note the motion of the back carrier rod N. The carriers on this rod.
will start from the selvedge z where it has been stopped by the selvedge stop D'
Figures 6 and 7 and will lay its thread from toy where it is stopped by the stop.
piece K' on the rod N coming in contact with the stop screw K
When it strikes the stop screw K the bolt L is up as shown in Figure 6, and the.
slide K' will therefore be in its central position.
When the sinkers are retiring the bolt L is lowered and the friction on the carrier-
rod N causes the stop piece K to press on the stop screw Kid whereby the slide K®
is moved up to the stop screw K". The carrier rod N is then in its correct position
to start the return course i.e. one "lead" beyond where it finished the last course.
In precisely the same manner the carrier rod D* is governed by the corresponding
mechanism at the other end of the machine.
Although the movements of the carrier rods have been described separately it will
I be understood that the three carriers start to lay their threads simultaneously.
When the "split-foot" is required to be carried beyond where the "toe-narrowings
commence so as to make a "split toe" or "three quarter toe" the clawker K
19-

page_text: Figure 5 is put into action so that the saddle. I will be racked in synchronously
with the ordinary slide stop D.
It will be seen in this case that when the saddle K is moved or narrowed inwards
the front carrier rod M will be moved in by the stop screw M Figures 6 and 7-but
the back and middle rods require other mechanism to draw them in. P is a hook,
or catch, which works on a pin, or axle, P¹ and is held up by a spring P' and is so
adjusted that when the stop piece K on the carrier rod N is against the stop
screw K, the latch P can pass over the stop piece K' and hold it against the stop
screw K. The top of the bolt L has a hook shaped extension 1 which passes
over the top of the latch P so that when the machine goes into narrowing a second
cam actuates the shaft L³ and lowers the bolt L sufficiently for its hooked end P
to pull down the latch P and hold it there while the saddle K is racked and so the
latch P pulls or narrows in the middle (and back) rod and thus the middle and back.
carrier rods are narrowed in simultaneously with the front carrier rod.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what I
claim is:
