Complete Specification Accepted, 14th Dec., 1888
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:-
The improvements relate mainly to knitting machines in which the needle bar
is divided into a number of short lengths each readily removable in the manner
described in the Specification of a Patent to William Cotton No. 3467 in the
year 1871.
Such machines are employed when work produced on another machine has
to have a piece spliced on to it as for example the foot of a stocking womens
vests &c. &c.
In machines of this kind it is desirable that the bar carrying the knocking over
bits should be capable of being raised or lowered to adjust their position according
to the work to be done, and machines of the kind known as Cotton's have in some
cases been made with the bar carrying the knocking over bits so capable of adjust-
ment when the bar has been set in front of the needles that is on the opposite side to
the sinkers.
This construction is however inconvenient as it interferes with the work being
carried away to the front. I remedy this by placing the bar carrying the knocking
over bits at the back of the bar carrying the needles and carrying it by supports
from lever arms below the lever arms by which the needles are raised and
lowered.
This leaves the space in front of the needles entirely open so that any of the
sections of the needle bar can be taken out or put in in the manner described in the
Specification of the Patent herein before mentioned.
If duplicate sections of the needle bar are provided work can be run on to one
whilst the other is in use in the machine.
As also there is in the machine plenty of space for work to lie in front of the
needles three or more pieces of work may be run on to the needles of a section.

COMPLETE SPECIFICATION.
Improvements in Knitting Machinery.
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 improvements relate mainly to knitting machines in which the needle bar
is divided into a number of short lengths each readily removable in the manner
described in the Specification of a Patent to William Cotton No. 3467 in the
year 1871.
Such machines are employed when work produced on another machine has
to have a piece spliced on to it as for example the foot of a stocking, women's
vests &c. &c.
In machines of this kind it is desirable that the bar carrying the knocking over
bits should be capable of being raised or lowered to adjust their position according
to the work to be done and machines of the kind known as Cotton's have in some
cases been made with the bar carrying the knocking over bits so capable of adjust-
ment when the bar has been set in front of the needles that is on the opposite side to
the sinkers.
This construction is however inconvenient as it interferes with the work being
carried away to the front. I remedy this by placing the bar carrying the knocking
over bits at the back of the bar carrying the needles and carrying it by supports
from lever arms below the lever arms by which the needles are raised and
lowered.
This leaves the space in front of the needles entirely open so that any of the
sections of the needle bar can be taken out. or put in, in the manner described in the
Specification of the Patent herein before mentioned.
"
If duplicate sections of the needle bar are provided work can be run on to one
whilst the other is in use in the machine,

page_text: As also there is in the machine plenty of space for work to lie in front of the
needles three or more pieces of work may be run on to the needles of a section
before it is placed into the machine. When placed into the machine work
can be. continued on the uppermost of these pieces of work whilst the others
lie out of the way at the bottom of the stems of the needles below the knocking
over bits.
The drawing hereunto annexed is a vertical section of so much of a knitting machine
constructed as above described as is necessary for shewing the manner in which I
carry out my invention.
A is the needle bar carried in the ordinary way at the top of arms B which are
supported by being jointed to arms C which extend from the needle bar shaft D.
This shaft is rocked in the ordinary way by arms extending from it and acted on by
cams on the cam shaft to raise and lower the needles at the proper times. The arms B
are also at their lower end jointed to rods E which rods are again jointed to levers F
that are acted on by cams on the cam shaft G.
By lifting the rods E and pushing them back the needles can be thrown forward
and put out of action in the ordinary way. Any one section of the needles can
in this way be thrown forward and put out of action whilst the other sections remain
in work.
When so thrown forward and put out of action work can be taken off from the
needles and fresh work run on to them or as above explained the sections of the bar
carrying the needles may be made to be readily detachable from the needle bar, A. so
that the bar. carrying the needles may be quickly taken off and another bar on which
work has previously been run be put in its place. Hare the knocking over bits carried
by leads I secured to a bar I which can move vertically up and down in guides J and
which at its lower edge is jointed to lever arms K' which extend from the knocking
over bit shaft K. Other arms K' extending from this shaft carry trucks L' which
rest against cams on the cam shaft G.
The height at which the knocking over bits are set can be adjusted by the guage
screws L which bear upon the axles of the trucks L'.
The cams against which the arms K² rest may be so formed as to give to the
knocking over hits a slight upward movement just at the time when a course of
work is being knocked over or they may rest simply upon circular discs on
the cam shaft and the knocking over bits be allowed always to maintain the same
position.
The carrying of the knocking over bits in this way is equally applicable to rib
frames as to plain frames."
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 :-
1. Placing the bar which carries the knocking over bits at the back of the needle
bar and carrying it by supports from lever arms from a shaft below the lever arms by
which the needles are raised and lowered.
2. The construction of knitting machinery substantially in the manner hereinbefore
described and illustrated in the drawing annexed.
