We, JOHN DALBY, 41 Oldham Street, Sneinton, Nottingham, Machinist, and
WILLIAM HUNT 285 Mansfield Road Carrington Nottingham, Machinist, do hereby
declare the nature of our invention to be as follows:-
Our improvements are applicable to straight bar knitting machines known as
Cottons Patent. But instead of securing the jacks in combs, cast in leads, by passing
a wire or wires through the jacks and combs, we secure the jacks in position by the
following means, at the back of the needle bar and sinker bar, we secure a flat plate
one to each division of the machine, the ends of the plates being carried by the
standards, upon each plate we place a right angled bar capable of adjustment and
having the upperside of the horizontal member grooved to receive a brass trick bar,
at the front and back of the trick bar, the upperside of the member stands somewhat
higher than the bottoms of the tricks in the brass bar, upon such higher portions the
bottoms of comb blades slide, being retained in position by the brass trick bar before
named, the front upper ends of the comb blades being held by vertical tricks in a
brass bar secured to the back of the vertical member of the right angled bar, each
comb blade is provided with an axle stud projecting from one side, upon each stud a
jack of suitable shape rocks. When the whole length of comb blades and jacks for
each division are placed in position they are firmly held in the two trick bars by means
of one or more clamping plates, the front edge of each of which presses upon the
back lower edge of the comb blades, each clamping plate being secured to the right
angled bar before named by two or more screws passed through the plate and a strip
of leather or other suitable material placed between the plate and the comb blades.
We are thus enabled to remove either a comb blade or a jack when either is bent
or strained and substitute a fresh one without disturbing the division.
And instead of a fixed knocking over bar or a vertically moving knocking over
bar we employ hooked knocking over bits cast in leads or secured in tricks, screwed
or otherwise secured to a knocking over bar, the ends of which slide upon brackets
secured to the standards, and when required the bar also slides upon an intermediate
bracket or brackets, secured to the framing of the machine, each sliding knocking
over bar is hinged on its underside to two or more hand links, by which it can be
moved towards the front of the machine for the convenience of the attendant, each

upon an axle pin carried by the upper end of an arm secured on a shaft rocking in
bearings carried by the framing, the shaft is provided with two or more truck bearing
levers each operated by a cam on the cam shaft.
By such means we are readily enabled to carry the loops of the fabric round the
heads of the needles by the arches of the hooked knocking over bits, with less pressure
than has heretofore been employed thereby producing a superior and more elastic
fabric.

improvements in Knitting Machines.
We JOHN DALBY 41 Oldham Street Sneinton Nottingham Machinist and WILLIAM
HUNT 285 Mansfield Road Carrington Nottingham 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:
DESCRIPTION OF THE DRAWINGS.
Figure 1 shows a full sized sectional view of portion of a knitting machine with
our improvements applied thereto.

page_text: But instead of securing the jacks in combs cast in leads by passing a wire or wires
through both jacks and combs."
We secure the jacks in position by the following means, at the back of the needle
bar and sinker bar we secure a plate A, one to each division of the machine, the ends
of the plates are secured to brackets A¹ cast on the standards, upon each plate we
place a right angled bar B capable of adjustment and having the upper side of its
horizontal member grooved to receive a brass trick bar B₁ at the front and back of
this bar the upper side of the member stands somewhat higher than the bottoms of the
tricks in the brass bar, upon such higher portions, the bottoms of comb blades C rest,
being retained in position by the trick bar, the front upper ends of the comb blades
have each a projection which are held by vertical tricks on a brass trick bar B² which
lies in a groove in the back of the vertical member of the bar B, each comb blade is
provided with an axle stud ( projecting from one side, upon each stud a jack D of
suitable shape rocks.
When the whole length of comb blades and jacks for each division are placed in
position, they are firmly held in the two trick bars by means of two or more clamping
plates B³ to each division, each plate being provided on its lower side with a strip of
leather or other suitable material, the front edge of which presses upon the back lower
edge of the comb blades as each plate is forced down by two or more screws B* each
of which passes through the plate and leather and is screwed into the bar B.
And
We are thus enabled to remove either a comb blade C or a jack D'when either is
bent or strained and substitute a fresh one without disturbing the division.
instead of a fixed knocking over bar or a vertically moving knocking over bar, we
employ hooked knocking over bits E cast in leads "as shown in the drawings" or
secured in trick bars screwed or otherwise secured to a knocking over bar E¹ the ends
of which slide horizontally upon brackets E² secured to the standards, and when the
width of the division requires it, the bar also slides upon an intermediate bracket or
brackets secured to the framing of the machine, each knocking over bar is hinged on
its underside to two or more hand links E³ each of which is slotted on its lower edge
to enable it to be lifted clear off, or be placed upon an axle pin E, when the links are
lifted clear off the pins by the attendent he is enabled to draw the knocking over bits E
carried by the bar E¹ towards the front of the machine clear of the needle bar when
a new needle lead is required in place of a broken one, or for other purposes, the axle
pins are each carried by the upper end of an arm E' secured on a shaft E which
rocks in bearings secured to the standards, the shaft is provided with two or more
truck bearing levers E each operated by a cam F¹ secured on the usual cam shaft F.
When the cam shaft is traversed to the right while the fabric is being narrowed, the
cams F will be clear of the trucks, which will lie on the cam plates F until the
narrowings or widenings are completed.
The movements of the hooked knocking over bits in combination with the needles
and loop forming sinkers "which are operated in the usual way
" are as follows:-
The needles being raised to their highest position and the hooked knocking over
bits being in the position shown at Figures 1 and 2 the thread is laid across the needle
just under the eyes as shown at 1 Figure 6 at the same time the slur cock operated in
the usual way strikes every alternate jack D which throw forward their sinkers G into
the position 2. The catch bar H carrying the locker bar I moves forward and carries
with it the other intermediate sinkers G, at the same time the needles are moved
slightly towards the front of the machine to enable the sinkers to form loops of equal
length then the catch bar falls to engage with the back upper ends of the whole of the
sinkers it then moves partly back taking the whole of the sinkers with it, at the same
time the needles fall back to press their beards into the eyes as the needles are lowered
and while the beards are being pressed the arched knocking over bits are moved to 3,
the needles having moved to 4, to land the loops well on to the beards of the needles
the knocking over bits move to and the needles fall to 6 and follow the course shown
by the dotted line to 7 and rise up to their first position ready for the thread to be
laid for the succeeding course, the hooked knocking over bits resuming their first
position as the needles rise such movements being repeated at each course.

page_text: By such means we are readily enabled to carry the loops of the fabric round the
heads of the needles by the arches of the hooked knocking over bits, with less pressure
than has heretofore been employed thereby producing a superior and more elastic
fabric.
The arches of the hooked knocking over bits receiving a bulk of fabric and 1. pre-
venting it from turning over the heads of the needles thereby enabling the attendant
to clear the fabric while it is being made and avoiding the necessity of employing
transferring bars for clearing purposes.
Having now particularly described and ascertained the nature of our said
Invention and in what manner the same is to be performed we declare that what we
claim is
1st. For the adjustable angle bar B provided with two trick bars B' and B' in which
comb blades C are placed and secured by clamping plates, each comb blade being
provided with an axle stud Cupon which a jack rocks substantially as described and
illustrated in the Drawings annexed.
2nd. For the knocking over bar E' carrying leads of arched or hooked knocking
over bits E and sliding horizontally being hinged on its lower side to hand levers E³
each of which engage with an axle pin E carried by an arm E' rocking with a
shaft E provided with a truck bearing lever F7 operated by cams F1 and F secured
on the usual cam shaft.
