IMPROVEMENTS IN TWIST LACE MACHINERY
Year: 1884

page_text: I, HENRY BLACKFORD PAYNE of Wyvill Terrace Hyson Green of the Town and
County of the Town of Nottingham Lace Manufacturer do hereby declare the
nature of my invention for "IMPROVEMENTS IN TWIST LACE MACHINERY
to be as
follows:-
"
Herefore a great drawback has existed in certain twist lace machinery commonly
known as "Levers Machines" " Go-through machines" and "Curtain machines"
by reason of the "bobbins" and carriages " used in some of the fine point
machines being so thin as to render it impossible to wind thick silk cotton or other
thread upon them.
By my improvements, hereinafter described, bobbins and carriages can be used
double the thickness or more, at the same time maintaining the guage of the
machine.
I will now describe the manner in which I carry my invention into effect.
In the "Levers," "Go-through" and "Curtain" machinery the "carriages"
which carry the bobbins are arranged side by side across the whole width of the
machine. These carriages ride in two comb bars (a front comb bar and a back
comb bar) and are actuated by catch bars, landing bars and other mechanism as is
well understood.
There are also two "point bars" used in the present machinery which take the
twist up from the tops of the carriages as they pass through the warp threads
which is also well understood.
In order to gain sufficient room for a carriage and bobbin double the thickness of
those used in machines at the present time I arrange the carriages in two or more
tiers one above the other as may be most advantageous.
For example I will take a 10 point "Levers" machine arranging the carriages in
two tiers only one above the other.
In a 10 point machine there are 20 carriages to the inch when they are in
position in the machine.
In order to use carriages and bobbins double the thickness, at the same time
working the same number of carriages to the inch (viz 20) I work one carriage
above the other-The carriages ride in comb bars as usual only there are two sets
of comb bars, and catch bars.
It will be seen that by working carriages in tiers (one above the other) gives, by
working them in two tiers just double the amount of room for each carriage.
When these two tiers of carriages are in position in the comb bars (which are
also one above the other back and front of the machine) the distance between the
pointed part or lead of the carriage (which is thinner than the top part of the
carriage, and rides in the comb) on the bottom tier is exactly two gaits.
The carriages in the top tier are also the same distance apart only the points or
leads of the carriages are placed above and just between those of the bottom tier
and consequently taking the two tiers of carriages together the distance between

page_text: the points or leads of each carriage alternately from the two tiers is exactly one
gait.
By this arrangement and method of working of the carriages I am able to
employ carriages and bobbins double the thickness thereby affording double the
room for the purpose of winding thick silk cottons or other thread upon the
bobbins.
This arrangement and working of the carriages necessitates the alteration of the
action of the point bars.
The take up of the points is extended.-Instead of the point bars taking the
twist up from the tops of the carriages they take the twist up from the perforated
bars which govern the position of the warp and other threads-therefore the
carriages pass through the warp and other threads when they are perfectly
perpendicular thus avoiding all possibility of wrong-gaiting as is frequently the
case in gimping in fine point machines. In fact the perpendicularity of the warp
and other threads acts as a guide to the carriages entering their proper gait.
The action of the point bars is reversed to that of an ordinary machine. Insteal
of the front point bar falling when the carriages are coming into the front comb
bar, the back bar falls and thus gets a clear passage to the bottom from whence it
takes up the twist-the back point bar falling when the carriages come into the
front comb bar.
In order to make room for the point bars to descend and secure their proper
position between the warp and other threads governed by the perforated or other
bars the sets of comb bars at the back and front are drawn away either alternately
or together as they are relieved of the carriages by means of suitable mechanisin
constructed for that purpose.
I do not limit myself to the use of two point bars as for certain purposes it
would be necessary to use more than two.
Mechanism is also applied to prevent the point bars from descending should the
catch bars miss the carriages thereby avoiding any damage which otherwise might
accrue to the points.
"
The tiers of carriages work together i.e. from back to front of the machine just
in the same way as the single tier is worked in machines of this kind at the present
time but I would have it understood that I do not confine myself to this as in
making certain classes of very heavy and other goods I work each tier of carriages
(in the case of two tiers being used) in opposite directions to one another and in
cases of more than two tiers I work them relatively in any direction I may find
most alvantageous.
For some purposes I may find it desirable to introduce weft threads into the
fabrics from selvage to selvage.
'
By my improved means of arranging and working bobbins and carriages double
the thickness or more in "Levers Go-through" and "curtain" machines I am
enabled to wind two or more threads of the same or different colours upon one
bobbin and at the same time getting a good length of cotton or other substance
upon the bobbin by reason of the extra size and greater space afforded by my
improvements.
When two or more threads of the same or different colors are wound upon one
bobbin a corresponding number of holes are provided at the top of the carriage
through which each thread passes.

I will now describe the manner in which I carry my Invention into effect.
In the "Levers" "Go through

When two or more threads of the same or different colors are wound upon one
bobbin a corresponding number of holes are provided at the top of the carriage
through which each thread passes.

into practice I will proceed to describe the same more in detail and with reference
to the drawings hereto annexed.
DESCRIPTION OF THE DRAWINGS.
Figure 1 is a transverse section of the machine shewing all the principal parts
illustrating the mechanism by means of which I carry my improvements into
effect.
a¹ and a represent two rows of carriages and bobbins in position in the machinė.
One row of carriages being above the other.
b' and b2 are the front and back comb bars of the top tier of carriages a¹.

page_text: The carriages ride in combs (63 and 6') which are secured in leads and fixed to
the comb bars 6¹ and b².
The top comb bars (61 and 6') are secured to feet c¹ in the front and c³ in the
back.
These feet are firmly secured to the bottom comb bars c³ and c. Thus the top
comb bars receive their action through the action of the bottom comb bars.
which
The bottom comb bars (c³ and c) which carry the comb leads and
receive the bottom row of carriages a³ are suspended on joints or arms ḍ and ď³
which work on the axis d.
The comb bar c³ is connected to the rocking shaft by means of the link e¹ and
the lever e².
This shaft e receives its motion by means of the curved lever e' being coupled to
the elbow truck bearing lever et by means of a connecting rod e³.
This truck bearing lever e' is worked by a suitable cam Figure 3 which is fixed
to the cam shaft x.
The back comb bar c has the same motion as the front comb bar c³ such motion
being given by means of the link fl and the lever f' which lever is secured to the
shaft f.
This shaft. f receives its motion by means of the curved lever f³ being coupled to
the double ended truck bearing lever f' by means of the short connecting rod f³.
This truck bearing lever f* is worked by means of a cam Figure 3 similar to
that working the truck bearing lever et.
There are two landing bars g¹ and g³ receiving the bottom row of carriages a².
These landing bars are suspended on the joints or arms d³ and d' which are hung
upon the axle d.
•
'
The landing bars g¹ and g³ are connected to the rocking shafts g³ and g* by means
of the links g and go and the levers 97 and 98.
These shafts g and g' receive motion by means of the elbow lever gone end of
which is secured to the connecting rod go and lever g¹¹ the other end being
connected to the rod g" which is worked by a crank g¹³ fixed to the front shaft Z.
The two bottom catch bars h¹ and h² are connected to the landing bars g₁ and 92
by means of a double jointed catch bar foot h³ and hª and thus receive their action
from the landing bars g¹ and g³.
The top catch bars h³ and he are secured to the single jointed catch bar feet h³
and h³.
These single jointed catch bar feet h7 and 8 are secured to the curved feet h°
and h¹0 at the top end, the bottom end of which feet h° and h¹º are secured to the
landing bars g¹ and g³ from whence the motion to the top catch bars he and h° is
effected.
Each catch bar is provided with a lifter h¹¹ h¹ worked by cam Figure 4 in the
usual way.
The point bars and are secured to and worked by, the point bar arms ³
and which are secured to the truck bearing levers j³ and which receive motion
from cams Figure 5 secured to the cam shaft x.
The knocking out arms 7 and 78. are connected at one end to the point bar
arms and j', the other end being connected to the truck bearing levers and 10
which receive the necessary knocking out motion from cams Figure 6 secured to.
the cam shaft a
The motion of the point bars is extended to take up the twist from the tops of
the perforated steel bars k instead of the tops of the carriage see j³ figure 2.
The point leads " and 1 are secured to the point bar in the manner shewn in
the Drawing Figure 2.
From the previous description and drawings a competent mechanic acquainted
with this class of machinery will readily understand how to apply my improvements
to the different arrangements "of "Levers” “Go through" and "Curtain twist lace
machine."

page_text: I would remark that the mechanism previously described for actuating the
several bars comb bars carriages and bobbins may be considerably varied without
departing from my invention consequently I do not limit myself thereto.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed I declare that I make
no claim to any of the mechanical parts separately which are well known and in
common use but what I claim is
First. The improved arrangement and working of bobbins and carriages in two
.or more tiers one above the other in "Levers" "Go through" and "Curtain" twist
lace machinery.
"
Second. The improved combination and working of bobbins and carriages in
"Levers Go through" and "Curtain" twist lace machinery substantially in the
manner hereinbefore described and represented in the drawings annexed.
Dated this 9th day of March 1000.
