Complete Specification Accepted, 14th Dec., 1888
1, 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:-
The object of my invention is to enable two or more differing portions of one piece
of work that is being formed on a knitting machine to be narrowed on both of their
sides.
To effect this I use in addition to the ordinary pair of point bars a second or
more pairs of point bars carried by independent lever aruis in a similar manner
to that described in the specification of a Patent granted to William Cotton
No. 989 in the year 1880 wherein two sets of point bars are described as being
used in a machine for producing ribbed work one set working with the machine
needles and the other with the frame needles.
The points carried from the two or more sets I. now make to work in one plane and
to work with one row of needles.
As the two or more sets of point bars are carried by independent lever arms each
set can be raised or lowered independently of the other-or either one
turned back and put out of action so that the free movement of the points of the
can be
other set or sets cannot be interfered with by it.
In such machines and in other machines in which a number of thread layers are used
and where it is required that some of the thread layers shall at times have a different length
of traverse to others I limit the extent of traverse of some of the thread layer bars
by a stop plate which can be set inwards by a screw as heretofore and the traverse
of the others I limit by a stop plate or plates set inwards by an additional screw
box or boxes mounted upon the ordinary one much in the same way as two screw
boxes are used for another purpose in the machine described in the Specification
of a Patent granted to William Cotton No. 6088 in the year 1882.
In this way all the stops can be set inwards or outwards simultaneously by the
irst screw box or the second ones only can be worked by the second screw or
་་

page_text: screws. Or the first stop can be set inwards or outwards whilst the second stop
or stops although set inwards or outwards together with it is correspondingly
moved in the opposite direction by the second screw and so practically remains
at rest.
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 :-
The object of my invention is to enable two or more differing portions of one piece
of work that is being formed on a knitting machine to be narrowed on both of their
sides.
To effect this I use in addition to the ordinary pair of point bars a second or more
pairs of point bars carried by independent lever arms in a similar manner to that
described in the specification of a Patent granted to William Cotton No. 989 in the
year 1880 wherein two sets of point bars are described as being used in a machine for
producing ribbed work one set working with the machine needles and the other with
the frame needles.
The points carried from the two or more sets I now make to work in one plane and
to work with one row of needles.
As the two or more sets of point bars are carried by independent lever arms each
sét can be raised or lowered independently of the other-or oither one can be turned
back and put out of action so that the free movement of the points of the other set or
sets cannot be interfered with by it.
Figure 1 of the drawings hereunto annexed is a vertical section of a row of needles
of a knitting machine with narrowing point mechanism arranged as above described
working therewith. Figure 2 is a part front view of the same.
A A are the needles-B are points carried by fingers from a point bar 1 which
can be slidden end wise through bearings in arms C which are secured to a shaft D
carried in bearings at the ends of arms E. These arms are fixed to a shaft F which turns
in fixed bearings on the frame of the machine. The shaft F can be rocked by the
action of cams on the cam shaft of the machine as explained in the specification of the
above mentioned patent to give the required movements to the points whenever they

page_text: are brought into action. The arms C also carry a second point bar 2 from which
other points not shown are similarly carried. They also carry slides G acted upon
whenever required by lever arms G on rods G to bring points into action for widen-
ing as will be well understood. The arms C can be turned upwards on the shaft D
so as to be out of the way at times when narrowings are not being made.
3 and 4 are the point bars carrying the second set of points H. The point bars are
similarly carried by arms from the rocking shaft F.
By using the points B for narrowing or widening one side of a piece of work and the
points II for the other side of a piece of work the narrowings or widenings on the
two sides can be effected simultaneously. Two parts of the same piece of work can
also be simultaneously narrowed or widened. The parts at which narrowings or
widenings take place are determined by the movements of the ordinary and by extra
screw boxes.
In machines provided as above described with two or with more pairs of point bars
and in other machines in which a number of thread layers are used and where it is
required that some of the thread layers shall at times have a different length of traverse
to others I limit the extent of traverse of some of the thread layer bars by a stop plate
which can be set inwards by a screw as 'heretofore and the traverse of the others I
limit by a stop plate or plates set inwards by an additional screw box or boxes mounted
upon the ordinary one much in the same way as two screw boxes are used for another
purpose in the machine described in the Specification of a Patent granted to William
Cotton No. 6088 in the year 1882.
In this way all the stops can be set inwards or outwards simultaneously by the first
screw box or the second ones only can be worked by the second screw or screws.
Figure 3 is a plan of so much of one end of a knitting machine provided with two
screw boxes as is necessary to show how this part of my invention may be carried into
practice. Figure 4 is an end view of the same. Figure 5 is a cross section of the
two screw boxes and Figure 6 is a side view of a stop plate which stands up from the
fixed frame and carries some of the stops for arresting the movement of the thread
layer bars.
A is the slide of the ordinary screw box which can be slidden endwise along a
bed secured to the fixed frame of the machine-it carries the bed B of a second
screw box as shown-C is the screw by which the slide A is traversed to and fro
and D the screw which is carried by the bed B and gives motion to the slide, E
which this bed carries.
In the arrangement shewn in the drawings a stop plate E¹ which extends from
this slide carries three stops for acting upon three of the thread layer bars but it
might carry stops for acting on any one or other of the thread layer bars as desired.
In the mechanism shewn in the drawings there are seven thread layer bars
1, 2, 3, 4, 5, 6 and 7 any of which can be put in or out of action as desired in the
ordinary way.
The endway movement of some of the thread layer bars when in work is arrested
by stops carried by a plate F fixed to the frame of the machine the movement.
of other of the bars is arrested by stops carried by a stop plate A' which extends
from the slide A-and the movement of others arrested by the stops on the stop
plate E' carried by the slide E.
The bar 1 passes through on opening in the plate F and is acted on by a stop 1ª on
the stop plate A¹ or the opening in the plate through which the bar is free to pass may
be closed by a slide 1° this slide will then itself form the stop for the end of the bar to
strike against.
The bar 2 passes through an opening in the fixed plate F, through an opening in the
stop plate A', so that its end may be acted on by a stop 2ª carried by the stop plate E¹.
The opening in the plate F through which this bar passes may also be closed
by a slide 2b which is used for holding the rod when not at work.
At the opposite end of the machine the bar would strike against a stop carried by a
fixed plate similar to the plate F.
The bar 3 strikes against a stop 3ª carried by the plate Fat the opposite end by the
•

page_text: -
machine it would strike against a stop on the slide of a second screw box similar to
the slide E.
EL
The bar passes through an opening in the plate F and its end comes against
stop 4 on the stop plate A¹ or a stop 4 carried by a slide G which slides in guides in
the plate F can be moved into the path of its travel.
The bar 5 passes through an opening in the plate F through an opening in the
stop plate A and comes against a stop 5ª carried by the stop plate 'E'. Ora
stop 5 carried by a slide H which slides in guides in the stop plate 'A' can be
brought into its path."
The bar 6 passes through the plate F and stop plate A' and cones' against a stop 6
carried by the stop plate E'.
The bar 7 comes against a stop 7ª carried by the plate F.
The stops 2 and 5 are carried by a slide J which slides into guides in the stop plate E¹
so that the stops can readily be taken away whenever desired when they might
otherwise be in the way-the stop 6ª is similarly carried by a slidė K which can be
withdrawn whenever necessary.
The screw C is left handed and can whenever required have a step by step rotating
movement given to it by the pegs of a peg wheel I on its axis being acted on by
a driver N to which an up and down movement is given as described. in the
specification of the Patent No. 608883.
The screw D can whenever desired have a step by step rotating movement given to
it by a ratchet wheel O on its axis being acted on by a driver P-it can also be quickly
turned by hand by a tooth wheel D' upon it gearing into a tooth wheel Q on the axis
of which is a crank handle by which it can be turned.
The screw D is right handed so that when turned by its driver it moves the slide E
in the same direction that the slide A is moved when the screw is turned by its
driver.
Either one or other of the drivers can be put into working position or both can be
put out of action by turning the cam plate R into one or other of three positions. It
can be retained in either of these positions by a spring catch S entering one or other
of three notches in its circumference.
Apparatus arranged as above described is especially adapted for making stockings
with the leg picee and instep striped in three colors and with the heel and toe pieces
narrowed and to make such stockings in one continuous length of work.
For making the striped leg piece the bars 1, 4 and 5-the stops 1 4 and 5 being
then used for controlling the movement of the bars and the bars being allowed to
traverse a distance sufficient for moving the thread eyes which they carry from one
side to the other of the full width of the leg piece.
When the heel pieces and instep are to be commenced the same bars and stops may
be used for forming the striped instep the traverse of the bars being then reduced to
width of instep by racking in the screw C to the width of instep required. At the
same time the bars 2 and 3, 6 and 7 are brought into action for forming the heel pieces
the stop plate E¹ being racked inwards from time to time as the requisite narrowings
in the heel pieces are made.
Any of the bars can be used when making the narrowings at the end of the toe
piece.
When the toe piece has been completed the operation can be reversed and a reversed
toc piece be next formed widenings being made in place of narrowings then a striped
instep is made and the two heel pieces when completing the instep and afterwards a
leg piece so that the work goes on continuously.
The thread layer 7 may also be used for putting in a splicing thread either in the
heel pieces or in the leg above the heel pieces.
Knitting mechanism constructed with a number of thread layer bars and with an
additional screw box carried by the slide of the ordinary screw box can be used for
forming many varieties of forms of work whenever narrowings have to be made
at two parts of the work whether these two narrowings are made at different times or
simultaneously.

page_text: It is more especially applicable for making pants womens vests &c. where it is
lesired at times to narrow or widen both sides of two parts of each half pant or other
article that is being made in the manner described in the Specification of a Patent
granted to William Cotton No. 3409 in the year 1874. With the apparatus in the
Specification of that Patent, when the piece has to be narrowed at both of its outer
sides the extra narrowing fingers have to be turned up out of the way and have to be
soparately set when it is wanted to make the two divided parts of the piece. This is a
most tedious arrangement and requires care in working.
With apparatus constructed with two narrowing machines as herein described all
the extra points can be taken out of work without altering their position and do not
require resetting when again brought into work.
As above stated also I do not restrict myself to the use of two screw boxes only as
3 or more might be similarly used and the stop plates carried by each of them
arranged to carry stops to act on any or all of the thread layer bars.
The extra screw boxes are equally applicable to rib frames as to plain or striped
frames.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, 1 declare that what I
claim is :-
:-
1. The construction of knitting machines with two sets of point bars both working
with the same row of needles and capable of being worked independently one of the
other:
2. The construction of knitting machines with two sets of point bars carried by
independent lever arms so that they can be raised or lowered independently one of the
other substantially as described.
3. The construction of knitting machines with an additional screw box or boxes for
controlling the action of the thread layer bars so that narrowings or widening may
be made on the two side edges of two parts of one piece of work.
4. The construction of knitting machines with an additional screw box or boxes
substantially as herein described the slide of one carrying the bed of another.
5. The arrangement of mechanism substantially as herein before described for con-
trolling the movement of the thread layer bars of knitting machines.
Dated this 6th day of November 1888.
