Tucked Fabric.
We, THOMAS KIDDIER, JAMES KIDDIER, and JOHN WILLIAM KIDDIER,
all of Bell Street Works, Arkwright Street, in the Town and County of the Town
of Nottingham, Hosiery Machinists, do hereby declare the nature of this invention
to be as follows:-
The object of our invention is to enable various patterns and designs of tuck
work to be produced such as required on the back of the hand of gloves or on hose
or other knitted fabric. To effect this we cause one or any desired number of the
needles to be held out from the ordinary presser at intervals to form the desired
patterns. To hold them back from the presser we cause the stems of such needles
as are not to have loops pressed off from them to be brought against projections on
a bar which is just below the level of the ordinary knocking over bits. The bar we
make capable of being moved forwards and backwards to bring it into or out of
acting position. When drawn back the loops on all the needles will be knocked off
in the ordinary manner but when moved forward the needles which are held back
by the projections upon it will retain their loops.
The bar may be moved forwards at the required times by a second bar at the
back of it to which an endway motion is imparted and which when drawn endwise
in one direction is by inclines also moved forwards and then moves forwards the bar
carrying the projections. Springs may be used to press back this latter bar when
the end way moving bar is moved in the opposite direction. Motion may be trans-
mitted to the endway moving bar from a lever acted upon by a serrated cam wheel
to which a step by step revolving motion is given by a ratchet wheel and pawla_ted
on by a cam on the main cam shaft.
If fabrics of a complicated nature be required the bar carrying the projections
may be shifted endwise as well as or instead of backwards and forwards so that at
one time the projections may act upon some needles and at other times upon others.
To shift the bar end wise into the positions required the bar may at each course and
just after loops have been pressed off from the needles be shifted end wise in one
direction to the full extent of its traverse and then be allowed to be drawn back by
the action of a spring to bring its end against one or other of a number of steps or
notches on a stop plate-this stop plate can be raised or lowered by the action of a
cam to which a step by step revolving motion is imparted.
The form of the stop plate and the cam may be changed to produce various
patterns the projections upon the bar may also be readily removeable to be changed
for others set in different positions.

Improvements in Rotary, Knitting Machines for Producing
'Tucked Fabric.
We THOMAS KIDDIER, JAMES KIDDIER, and JOHN WILLIAM KIDDIER,
all of Bell Street Works, Arkwright Street, in the Town and County of the Town
of Nottingham, Hosiery Machinists, 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 our invention is to enable various patterns and designs of tuck work
'to be produced such as required on the back of the hand of gloves or on hose or
tother knitted fabric. To effect this we cause one or any desired number of the
needles to be held out from the ordinary presser at intervals to form the desired
patterns. To hold them back from the presser we cause the stems of such needles
as are not to have loops pressed off from them to be brought against stops or
projections on a bar which is just below the level of the ordinary knocking over bit.
The bar we make capable of being moved forwards and backwards to bring it into
or out of acting position. When drawn back the loops on all the needles will be
iknocked off in the ordinary manner but when moved forward the needles which are
held back by the stops or projections upon it will retain their loops.
The bar may be moved forwards at the required times by a 'second bar at the
back of it to which an end way motion is imparted and which when drawn endwise
in one direction is by inclines also moved forwards and then moves forwards the
'bar carrying the projections. Springs may be used to press back this latter bar
when the endway moving bar is moved in the opposite direction. Motion may be
-transmitted to the endway moving bar from a lever acted upon by a serrated cam
wheel to which a step by step revolving motion is given by a ratchet wheel and
pawl-acted on by a cam on the main cam shaft.
If fabrics of a complicated nature be required the bar carrying the projections
i may be shifted end wise as well as or instead of backwards and forwards so that at
one time the projections may act upon some needles and at other times upon
others, its position may then be controlled by a notched stop plate and pattern
-surface..:
The form of the stop plate and pattern surface may be changed to produce
\various patterns the projections upon the bar may also be readily removeable to be
changed for others set in different positions.

DESCRIPTION OF DRAWINGS.
In the drawings annexed we shew the manner in which we prefer to carry out
this invention.
Figure 1 is a vertical section of parts of a rotary knitting machine.
Figure 2 a front view of the same.
Figure 3 a plan of slide bars.
Figure 4 is also a vertical section of parts, and
Figure 5 à front view of such parts.
Z is the ordinary presser formed by the front edge of the fixed sinker bar.
Y are the sinkers. ✗ are the needles on the needle bar X' which as usual is
carried at the top of a lever W jointed at W¹ to a lever V which when rocked by
a cam on the main cam shaft a raises and lowers the needles.
The lower end of the lever W is also as usual coupled by a link T to a lever S
rocked by a cam on the cam shaft and by it the needles are caused to be brought
against the presser Z to close their beards or moved away from it to allow the
hearde to anou

The bars
to the pattern required. n is the second bar at the back of the bar s.
are supported on brackets Q affixed on the tie bar r and can be moved backwards
and forwards in these brackets.
u are springs bearing against the front of the bars and pressing both bars back-
wards. p (see Figure 3) are inclines on the back of the bar n to give a forward
movement to both bars when the bar n is drawn endwise, the inclines then coming
against a portion of the brackets Q. In place of the bar n being moved horizontally
a bar having a vertical movement may be employed.
In the arrangement shewn in the drawing the barn has an endway movement
given to it at the proper times in the following manner.
On the main cam shaft a Figure 1 is affixed a cam 6 acting on a truck c carried
by a lever d which for convenience may be the ordinary shogging lever. The
lever d is by the link e coupled to the lever f and gives to it a to and fro motion.
The upper end of the lever carries a pawl y working into a ratchet wheel h
affixed to a star wheel i which thus receives a step by step revolving motion
and gives motion through the truck j and bell crank lever k to a connecting rod
coupled to another bell crank lever m which is coupled to the slide bar n.
For simple patterns the bars may be restrained from moving endwise by stops
fixed to it one on either side of one of the brackets Q.
If fabrics of a complicated nature be required we provide an additional wheel v
Figures 4 and 5 worked after the manner herein before described, the wheel v is
provided with an endless chain to on which are mounted a number of studs
according to pattern required, these are arranged in two rows and are capable of
being affixed in any desired position on the chain. On the main cam shaft a is
affixed a cam y working two trucks z and a' mounted one on each of the bell cranked
levers, c', these levers carry or have coupled to them projections d¹e. The
cam y when it acts on the trucks z and a' causes the projections d'e¹ to be held
away from the projections on the pattern chain. When the cam y has passed
beyond the trucks the ends of the levers which carry the trucks are drawn inwards
towards the cam shaft by the action of springs not shewn in the drawings-and the
projections d' are thereby brought against projections on the endless chain.
The lever b¹ is connected through the link and lever j' to the connecting link ¹
operating on a stop plate and the bars is at all times held up to this stop plate
by the action of a spring not shewn in the drawings.
The lever c' operates on the slide bar n through the connecting rod / and
lever m.
The stop plate is formed with steps or notches g¹ which act as abutments to
limit the end wise traverse of the bars according to the pattern required.
The action is as follows:-
When the cam y acts on the truck a' carried by the lever c it draws the bar n
end wise and locks the bar s in the manner before explained at the same time moving
the projection e¹ to its furthest distance from the endless chain-the projection d
is also similarly moved to its furthest distance from the chain after the bars has
been locked in position.
The chain is now moved one step in the manner before explained-a new stud
is in this way brought opposite to the projection d' and in some cases another is
brought opposite to e. If no stud has been brought opposite to e¹ then when the
cam y has passed beyond the trucks z and a' the bar s is unlocked by the arm of
the lever which carries the truck a' being drawn inwards towards the cam shaft
at the same time the arm of the lever 6' which carries the truck z is also drawn
inwards towards the cam shaft until the projection d' strikes against the stud which
has been brought opposite to it and the bars is thereby brought into the position
required for the next course its position being dependent upon the height of the
stud against which the projection d' rests and when the cam y again acts upon the
truck the bars is locked in this position during the time that the machine is
pressing a course of work or if the bar is required to be held forward while
20

page_text: several courses are pressed then at each movement of the pattern chain a pro-
jection is brought opposite to the projection-el-and-whilst these courses are being
made the bar n receives no endway movement and the bars remains locked.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed,.we declare that what we
claim is :-
1. The construction of rotary knitting machines in such a manner that tuck work
can be produced upon them by such needles as are not to have loops pressed off
from them being brought against stops situated just below the level of the knocking
over bits and so being held away from the ordinary presser whilst the other needles
are pressed against this bar in the usual manner.
2. Carrying the stops upon a bar which can be moved backwards and forwards to
put the stops into or out of action.
3. Carrying the stops upon a bar which can be moved endwise as well as or
instead of being moved backwards and forwards.
4. The arrangements of mechanism for producing tuck work in rotary knitting
machines substantially as herein before described and illustrated in the drawings
annexed..
