town of Nottingham for an invention of "IMPROVEMENTS IN THE CARRIAGES
OF BOBBIN NET OR TWIST LACE MACHINERY.”
PROVISIONAL SPECIFICATION left by the said Henry Blackford Payne at
the Office of the Commissioners of Patents on the 22nd February 1882.
HENRY BLACKFORD PAYNE of the Town and County of the Town of Nottingham.
"IMPROVEMENTS IN THE CARRIAGES OF BOBBIN NET OR TWIST LACE MACHINERY."
My improvements in the carriages employed or used in bobbin net or twist lace
machines relate to certain hereinafter mentioned means for covering or guiding the
threads over the bobbin at that particular point or place where the warp or other
threads are likely to catch and thus preventing the bobbins from cutting out the
warp or other threads in their usual course of working.
The carriages now employed in the above machines have a spring for keeping
the bobbins in their proper position the said springs being of an uniform thickness
and a little finer than the thickness of the carriage.
Now the first part of my improvements consists in having that part or portion
of the spring which is opposite that particular point or place of the bobbin where
the warp or other threads are first likely to catch stamped pressed or flattened so
that the stamped presser or flattened portion of the spring shall project from each
side of the surface of the carriage at that point or place of the bobbin that
requires covering.
The above description only covers or protects the bobbin at the front or one half
of the carriage.
According to my Invention I use the same means to cover or protect the bobbin
at the back part or other half of the carriage only in this case I use the spring
at the back or in any other position which may be found most advantageous for
the purpose.
When the protecting cover is not used as a spring the end where the nib would
be is soldered in the carriage.

page_text: In accordance with my invention I also use a continuous or half circle spring
with the nib in the middle and made and applied at the ends similarly to the
above.
The second part of my improvements relates to the use and application of a
double verge at the back part of the carriage for a certain distance in combination
with the spring first mentioned above or vice versa or in any other suitable position
as may be found most advantageous the said double verge being for the same
purpose of covering or protecting the bobbin and passing of the threads at that
particular point or place mentioned above.
My improvements also relate to the use and application of all and every of the
above arrangements which may be found most advantageous for particular and
various purposes to effect the covering of the bobbin and protection of the threads
at that particular point or place where the warp or other threads are likely to
catch either by soldering on stamping punching or any other equivalent means by
which projections or coverings can be applied for the purposes aforesaid except
those claimed in the Specification of Letters Patent granted to J. R. Hancock and
W. Smith dated 29th October 1881 No. 4733.
My improvements enable me to use carriages of one uniform thickness thus
dispensing with the expense of grinding but I find it advantageous according to
this part of my invention to grind the carriages only on one side for the reason
that it enables me to apply my improvements to existing machinery and retain
the customary thickness and strength of the comb.

the said Henry Blackford Payne in the Great Seal Patent Office on the
21st August 1882.
HENRY BLACKFORD PAYNE of the Town and County of the Town of Nottingham,
"IMPROVEMENTS IN THE CARRIAGES OF ROBBIN NET OR TWIST LACE MACHINERY.
My improvements in the carriages employed or used in bobbin net or twist lace
machines relate to certain hereinafter mentioned means for covering or guiding the
threads over the bobbin at that particular point or place where the warp or other
threads are likely to catch and thus preventing the bobbins from cutting out the
warp or other threads in their usual course of working.
The carriages now employed in the above machines have a spring for keeping
the bobbins in their proper position the said springs being of an uniform thickness
and a little finer than the thickness of the carriage.
Now the first part of my improvements consists in having that part or portion
of the spring which is opposite that particular point or place of the bobbin where
the warp or other threads are first likely to catch stamped pressed or flattened so
that the stamped pressed or flattened portion of the spring shall project from each
side of the surface of the carriage at that point or place of the bobbin that requires
covering.
.
The above description only covers or protects the bobbin at the front or one half
of the carriage.
According to my invention I use the same means to cover or protect the
bobbin at the back part or other half of the carriage only in this case I use the
spring at the back or in any other position which may be found most advantageous
for the purpose.
When the protecting cover is not used as a spring the end where the nib would
be is soldered in the carriage.
In accordance with my invention I also use a continuous or half circle spring
with the nib in the middle and made and applied at the ends similarly to the
above.
The second part of my improvements relates to the use and application of
double verge at the back part of the carriage for a certain distance in combination.
with the spring first mentioned above or vice versa or in any other suitable
position as may be found most advantageous the said double verge being for the
same purpose of covering or protecting the bobbin and passing of the threads at
that particular point or place mentioned above.
My improvements also relate to the use and and application of all and every
of the above arrangements which may be found most advantageous for particular
arrangements of lace machines used for various purposes to effect the covering
of the bobbin and protection of the threads at that particular point or place
where the warp or other threads are likely to catch either by soldering or stamping
punching or any other equivalent means by which projections or coverings can
be applied for the purposes aforesaid except those claimed in the specifications
of Letters Patent granted to J. R. Hancock and W. Smith dated 29th October
1881 No. 4738 and to William Spowage dated 3rd November 1881 No. 4815.
My improvements enable me to use carriages of one uniform thickness thus
dispensing with the expense of grinding but I find it advantageous according to
the part of my invention to grind the carriages only on one side for the reason that
it enables me to apply my improvements to existing machinery and retain the
customary thickness and strength of the comb.
And in order that my invention may be clearly understood and readily carried
into practice I will proceed to describe the drawings hereto annexed.

page_text: DESCRIPTION OF THE DRAWINGS.
Figure 1 shows the side view of a carriage of a bobbin net or twist lace machine
in which the spring at the front is flattened or expanded at the part a a so as to
project from the surface of the carriage on each side thereof such projecting
surfaces at their highest part being higher than the surface of the bobbin thus
acting as a cover thereto to prevent the edge of the bobbin from catching the
warp threads as the carriage passes through the threads from front to back of the
machine or vice versa. These projecting surfaces rise gradually from the surface
of the carriage to their highest point and then descend to the surface of the
carriage thus forming a double incline or curved surface projecting from each side of
the carriage (as shewn by the edge view of a carriage at Figure 4) which will
glide through or between the threads without any sudden action or check upon the
threads the warp threads are thus guided over the bobbins by the covering or
projecting surfaces without being injured.
A similar spring or it may be a wire is let into the back part of the carriage the
part from b to b being flattened or expanded in like manner to the part a a of the
spring at the front as previously described to serve as a cover on that part of the
carriage. The top end or nib may either be free to act as a spring or be soldered
or otherwise fixed in the surface of the carriage when fixed or soldered in the
carriage it adds great strength to the breast of the carriage either back or front or
both as may be desired and the position of the spring and projecting surfaces may
be so placed as to act in the most advantageous and effective manner to suit the
particular machine to which they are applied.
The projecting surfaces previously described may be so formed as to serve as a
cover or as a lead to a cover to protect the bobbin.
If desired a half circle spring with the nib in the middle may be used the sides
of the spring being expanded on each side of the carriage to form projecting
covering surfaces as previously described.
Another part of my improvements relates to the use and application of a double
verge at the back of the carriage for a certain distance in combination with the
projecting surfaces of the spring as previously described or vice versa and arranged
in any suitable position as may be most advantageous when applied to any
particular machine. The double verge is so formed as to project from the sides of
the carriage at any particular point required for the purpose of protecting the
⚫ bobbin and guide the passing of the threads over it.
The double verge is produced by beating out the carriage at that particular
point or place required to cover the bobbin and then it is ground out so
as to form a groove for the bobbin to ride in and thus form a cover to protect the
threads.
The same result may be obtained by soldering or riveting a thin steel or other
metal plate on each side of the carriage so as to form a double verge and cover for
the bobbin the front part of the carriage having a spring formed with projecting
surfaces for the purpose previously described.
Figure 2 shows a carriage in which the front and back edges or breasts of the
carriage or the inside edge of the carriage are stamped pressed or flattened out at cc
and d d so as to form projecting surfaces on one or both sides in such manner as to
cover and protect the bobbin in its passage between the threads in accordance with
this part of my improvements such projecting surfaces being graduated in extent
from one end to the other so as to glide readily between the threads.
The top part of the carriage at e may also be stamped pressed out and flattened
to form projecting surfaces to form a cover or lead to a cover to guide the bobbin
through the threads.
Figure 3 shows a carriage formed with a projecting curved line of metal ƒ ƒ
produced either by grinding stamping pressing riveting on soldering or other-
wise just above the combs also to serve as a cover or lead to a cover in

page_text: combination with any or either of the arrangements previously described for this
purpose.
According to another part of my improvements I grind that part of the carriages
which pass into and out of the combs on one side only by which I am enabled to
apply my improvements previously described to existing machinery and thereby
retain the customary thickness and strength of the combs.
Another part of my improvements consists in providing a support for the bobbin
at the bottom of the carriage or in any other suitable position to be used in
combination with my improvements in carriages as previously described such
support being knocked down out of the solid stamped pressed punched soldered or
riveted on or otherwise formed for the purposes of serving or acting as a support
only for the bobbin such bobbin (in the event of its being a little swelled out or
expanded) being likely to get down lower than the verge and over the carriage
when the carriage is thinner than those hitherto used.
Having thus described the nature of my invention and the manner of
performing or carrying the same into practice, I would remark that I do not
intend to limit myself to the exact details herein before described so long as the
novel features of my Invention are retained. At the same time I do not claim any
of the parts separately which are well known and in common use. I am also
aware that a Patent has been granted to William Spowage dated 3rd November
1881 No. 4815 the Specification of which describes the application of studs on the
carriages to prevent wrong gateing I therefore make no claim thereto, but what
I claim is;-
First. The improved method of forming and applying a cover or protecting
surfaces to the carriages of bobbin net or twist lace machines by using springs
broader than the thickness of the carriage or by expanding the springs on each
side of the carriage at the front and back in order to guide the warp or other
threads over the edge of the bobbin substantially in the manner and for the
purpose bereinbefore described and represented in Figure 1 of the drawings hereto
annexed.
Also the use and application of a spring or wire when soldered or otherwise
fastened in the carriage at both ends as a support or mode of strengthening the
breast of the carriage either back or front or both substantially as hereinbefore
described and represented in the drawings annexed.
Second. I claim the stamping pressing flattening or causing part of the edge
or breast or the inside edge of the carriage to project out at the front and back to
form a covering or lead to a covering substantially as and for the purpose herein-
before described and represented in Figure 2 of the drawings hereto annexed.
Third. I claim the arrangement and application of a double verge to act as a
cover to the bobbin for protecting the warp or other threads substantially in the
manner and for the purpose herein before described.
Fourth, I claim the grinding of the carriage top and bottom on one or both
sides so as to leave a projecting line of metal at the bottom of the carriage just
above the combs or in any position for forming a cover or lead to a cover to the
bobbin substantially as and for the purpose herein before described and
represented in Figure 3 of the drawings hereto annexed.
I also claim the stamping pressing riveting or soldering on or otherwise forming
a projecting line of metal upon the carriage to act as a cover or lead to a cover in
combination with springs and other parts substantially in the manner and for the
purpose herein before described and represented in Figure 3 of the drawings
hereto annexed.
Fifth, I claim the grinding on one side only of that part of the carriage which
rides in the comb substantially as and for the purpose hereinbefore described.
Sixth, I claim the providing of a support g for the bobbin at the bottom of the
carriage or in any other suitable position to be used in combination with my
improvements in carriages such support being knocked down out of the solid
stamped pressed punched or riveted on or otherwise formed so as to serve or act

page_text: as a support for the bobbin only substantially in the manner and for the purpose
herein before described and represented in the drawings hereto annexed.
Seventh. I claim the use and combination of all or any of the methods for
covering or protecting the bobbins and warp or other threads of bobbin net or
twist lace machinery as also the use and combination of all or any of the methods
employed as leads to coverings substantially as and for the purposes herein before
described and represented in the drawings annexed.
In witness whereof I the said Henry Blackford Payne have hereunto set my
hand and seal this Fifteenth day of August in the year of our Lord one
thousand eight hundred and eighty two.
