page_text: LETTERS PATENT to Henry Yates, of Rue Lafayette, St. Pierre les
Calais, in the Empire of France, Manufacturer, for the Invention
of "IMPROVEMENTS IN MEANS OR APPARATUS APPLICABLE TO BOBBIN NET
OR TWIST LACE MACHINERY, OR OTHER MACHINERY ARRANGED AND OPERATING
IN A SIMILAR MANNER."
Sealed the 27th August 1869, and dated the 30th June 1869.
PROVISIONAL SPECIFICATION left by the said Henry Yates at the
Office of the Commissioners of Patents, with his Petition, on the
30th June 1869.
I, HENRY YATES, of Rue Lafayette, St. Pierre les Calais, in the
Empire of France, Manufacturer, do hereby declare the nature of the
said Invention for "IMPROVEMENTS IN MEANS OR APPARATUS APPLICABLE
TO BOBBIN NET OR TWIST LACE MACHINERY, OR OTHER MACHINERY ARRANGED
AND OPERATING IN A SIMILAR MANNER," to be as follows:-
My improvements relate to means or apparatus for carrying or throwing
an extra thread or extra threads across or partially across bobbin net or
twist lace machinery (or machinery arranged and operating in a similar

page_text: "
manner) in such position that the extra thread or extra threads so carried
or thrown across or partially across the machine may be "taken up
and woven into the fabric in course of manufacture.
In carrying out my improvements I employ a thread carrier or thread
carriers, supported in front or at the back of the warp threads, or in
front as well as at the back of the warp threads, and below the bobbin
carriages, except in machines in which the "circle" of the machines is
inverted, and the work as produced is carried downwards, in which case
the thread carrier or thread carriers will be arranged above the bobbin
carriages. These thread carriers are supported by and affixed to slides
or carriages, which are supported so as to be capable of sliding on bars
extending from end to end of the machine, and are so formed as to pass
between the warps and the front or back combs and bobbin carriages.
These slides or carriages supporting and carrying the thread carriers are
carried or thrown the desired distance across the machine by means of
a series of levers, which are linked together in manner similar to what are
commonly known as "lazy-tongs." To one of the levers at the end of this.
series of levers or "lazy-tongs" a bar or rod is connected, which is by pin.
joint connected to one of a pair of levers which at one end are capable of
movement on an axis, and at their other end are provided with trucks
or bowls capable of being acted upon by a cam or tappet to give the
required backward or forward motion to the bar or rod affixed to the
end of the lever at the end of the series of levers or "lazy-tongs," in order
to expand or contract this series of levers, and carry or throw the thread
or threads carried by the thread carrier the required distance across the
machine. Motion is communicated to the cam or tappet giving motion
to the series of levers or "lazy-tongs" by means of a ratchet wheel affixed
on the same axis, which is caused to revolve as required by means of
a clawker or driver connected to one end of a lever to which motion is
communicated by means of a cam or tappet affixed by preference on the
main or driving shaft of the machine. In place of employing a double
series of levers, as in "lazy-tongs," I in some cases employ a single series
or half the number of levers so employed, in which case cach lever of the
series is arranged to turn at its centre on an axis carried by a slide or
carriage capable of sliding on the bar supporting or guiding the slide
carrying the thread carrier. In some cases when more than one thread
carrier is used I employ a separate series of levers and parts connected
therewith to act on each thread carrier, or a series of thread carriers may

series of levers and parts acting therewith, and this will be particularly
the case when making a series of breadths of fabric on the same machine.
A spring or springs affixed to the end of one of the series of levers may be
employed to draw or force the same together, or apart, in place of
employing a pair of levers to be acted upon by the cam or tappet, giving
the required backward or forward motion to the bar or rod connected to
the end of the series of levers which give motion to the thread carriers..
When it is required to throw a thread or threads only partially across
the machine, I omit a bobbin carriage or bobbin carriages at the point
where the thread carrier will remain during the backward & forward
motions of the bobbins and carriages. The motions of the thread carriers
are so timed that they shall throw or carry the thread or threads across
or partially across the machine as required when the bobbins and
carriages are in the front or back combs, as the case may be. Instead of
employing a ratchet wheel driven by a "clawker or driver," as described,
to give motion to the cam or tappet actuating the series of levers which
operate to throw the thread carrier across the machine, motion may be.
communicated by cog wheels or other suitable gearing. By the appli-
cation of apparatus as described extra threads may be thrown across or
partially across the machine and worked into the fabric without
necessitating the stopping of any part of the machinery to give time for
the throwing of the thread or threads, or reducing. the speed of the
ordinary bobbin net machino, and various modifications of bobbin net
fabric may be produced, or fabrics may be made similar to those now
produced in the ordinary weaving loom.
SPECIFICATION filed in pursuance of the conditions of the Letters
Patent, and of an Order of the Lord Chancellor, by the said Henry
Yates in the Great Seal Patent Office on the 3rd January 1870.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, HENRY
YATES, of Rue Lafayette, St. Pierre les Calais, in the Empire of France,
Manufacturer, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Thirtieth day of June, in the year of
our Lord One thousand cight hundred and sixty-nine, in the thirty-

page_text: third year of Her reign, did, for Herself, Her heirs and successors,
give and grant unto me, the said Henry Yates, Her special
licence that I, the said Elenry Yates, my executors, administrators,
and assigns, or such others as I, the said Henry Yates, my exe-
cutors, administrators, and assigus, should at any time agree with,
and no others, from time to time and at all times thereafter during
the term therein expressed, should and lawfully might make, use,
exercise, and vend, within the United Kingdom of Great Britain and
Ireland, the Channel Islands, and Isle of Man, an Invention for "In-
PROVEMENTS IN MEANS OR APPARATUS APPLICABLE TO BOBBIN NET OR TWIST LACE
MACHINERY, OR OTHER MACHINERY ARRANGED AND OPERATING IN A SIMILAR
MANNER," upon the condition (amongst others) that I, the said Henry
Yates, my executors or administrators, by an instrument in writing
under my, or their, or one of their hand and seals, should particularly
describe and ascertain the nature of the said Invention, and in what
manner the same was to be performed, and cause the same to be filed in
the Great Seal Patent Office within six calendar months next and
immediately after the date of the said Letters Putent.
NOW KNOW YE, that I, the said Henry Yates, do hereby declare
the nature of the said Invention, and in what manner the same is to
be performed, to be particularly described and ascertained in and by
the following statement thereof, that is to say :-
My improvements relate to means or apparatus for carrying or
throwing an extra thread or extra threads across or partially across
bobbin net or twist lace machinery, or machinery arranged and
operating in a similar manner, in such position that the extra thread
or extra threads so carried or thrown across or partially across the
machine may be "taken up' "and woven into the fabric in course of
manufacture.
In carrying out my improvements I employ a thread carrier or thread
carriers supported in front or at the back of the warp threads, or in front
as well as at the back of the warp threads, and below the bobbin
carriages, except in machines in which the "circle" of the machine is
inverted and the work as produced is carried downwards, in which case
the thread carrier or thread carriers will be arranged above the bobbin
carriages. These thread carriers are supported by and affixed to slides
or carriages which are supported so as to be capable of sliding on bars
extending from end to end of the machine, and are so formed as to pass

page_text: is a thread carrier, which in the arrangement shown is arranged to
operate in front of the warp threads c' and below the bobbin carriages f
The thread carrier is supported by and affixed to the slide or carriage j',
which is supported with capability of sliding on the bar, which
extends from end to end of the machine in position to guide the thread
carrier in its traverse across the machine in front of the warps and
between the front combs e and the back combs e. Motion is communi-
cated to the carriage to carry or throw its thread carrier j and
consequently the thread carried thereby across or partially across the
machine by means of a series of levers %, which are connected together
at their ends by pin joints, as shown. are supports which pass
through each pair of levers, and by the aid of screw nuts, Figures
13 and 14, serve to hold the levers in their proper position, whilst at
the same time they form the axes upon which the levers turn. The
levers are supported by means of the supports *, one end of each of
which is arranged to slide on the bar 7, whilst the other is supported
with capability of sliding in the groove in the bar . m is a bar or
rod, which at one end is connected to one of the supports of the
series of levers k, whilst at the other end it is connected by pin joint m'
to one end of an lever n, which is capable of movement on its axis »',
and at its other end is provided with a truck or bowl in position to
be acted upon by a cam or tappet n³; n' is another lever turning on an
axis a³, and carrying a truck or bowl in position to be acted upon by
the cam or tappet a³; 7 is a rod or link, which at one end is fixed with
capability of movement on the axis of the truck or bowl n³, and at
the other end is affixed with capability of movement on the axis #" of
the truck or bowl n, in order to give simultaneous motion to the levers #
and to give the required backward and forward motion to the bar or
rod m to expand or contract the series of levers, and carry or throw
the thread or threads (carried by the carrier 5) across the machine; *

tappet by means of the ratchet wheel » affixed on the axis
cam or tappet ». The ratchet wheel is caused to revolve as required
by means of a clawker or driver o connected to one end of a lever p,
which at one end turns on an axis p', and is provided with a truck or
bowl p² in position to be acted upon to raise or lower the lever p by
means of a cam or tappet q, which is by preference aflixed on the main
or driving-shaft. b.

page_text: In Figure 1 the apparatus is shown in the position the respective
parts will assume when the thread carrier has passed from one side to
the other of the machine, and the respective parts of the apparatus for
throwing the thread or threads across the machine will remain in these
6 respective positions until the cam or tappet q in the course of successive
revolutions has caused the lever p to actuate the clawker or driver o
to cause the ratchet wheel ' and consequently the cam ³ to make
successive partial revolutions. The truck or bowl will then pass from
the point 1 over the surface 2 of the cam or tappet n to the point 3,
without altering the position of the respective parts of the apparatus for
actuating the thread carrier. The truck or bowl will then be raised
by the increasing diameter of the can or tappet n until it arrives at
the point 4, when it will have raised its end of the L lever and caused
the bar or rod m to actuate the series of levers k, and by this means a
thread or threads will have been thrown or carried across the machine,
and the parts will assume the position shown by Figure 3. a, a, are
supports to the bars j and 1.
Figures 4, 5, and 6 shew separate views of the thread carrierj on a larger
scale, by which it will be seen that a groove and guides are formed
thereon to receive and guide the thread or threads after they have
passed from the bobbin or spool through the warp slea d up to the
lower end of the carrier j, when they will pass up the groovej and be
drawn off through the loop or eye. Figures 7, 8, 9, 10, 11, 12, 13,
and 14 show detail views of parts also on a larger scale. Figure 15 shows
a sectional front view of a slight modification of my. Invention.
According to this modification the parts are arranged and operated
in exactly similar manner to that already described, except that in
this case I employ two series of levers to actuate the same thread
carrier j, one end of both sets being connected to the carriage of the
thread carrier j, whilst their other ends are connected to the bar j² at
opposite ends of the machine, and the bar instead of being stationary,
as in Figures 1 and 2, is affixed at and to one of the supports *,
at the opposite ends of each of the series of levers k, and this bar lis
caused to traverse to and fro with those supports by means of the
bar or rod which is affixed to it by pin joint at ", by which means
both series of levers are caused to traverse simultaneously to throw
and consequently a thread or threads across the
machine, and in their traverse one and then the other series of levers
or carry the carrier

page_text: will be alternately expanded and contracted; are pullics or guides,
which are formed with grooves in their circumference to receive and
guide the bar in its motion to and fro. The pullies or guides turn
on centres carried by brackets a from the main framing. In some
cases, when it is required to employ more than one thread carrier on the
same side of the warp threads, I employ a separate series of levers k
and parts connected therewith to operate each thread carrier, whilst in
other cases a series of thread carriers may be connected together so as
to be capable of being actuated by the same series of levers and parts
acting therewith, and this will be particularly the case when making a
series of breadths of fabric on the same machine. A spring or springs
may be employed affixed to the end of one of the series of levers
to draw or force the same together or apart in place of employing
a pair of levers, as at n and n', Figures 1 and 2, to be acted upon
by the cam or tappet to give the required backward or forward
motion to the bar or rod m connected to the end of the series of levers
k giving motion to the thread carrier j. When it is required to throw
a thread or threads only partially across the machine, I omit a bobbin
carriage or bobbin carriages at the point where the thread carrier will
remain during the backward and forward motions of the hobbins and
carriages. The motions of the thread carriers are so timed that they
shall throw or carry their thread or threads across or partially across
the machine as required when the bobbins and carriages are in the front
or back combs, as the case may be. Instead of employing a ratchet
wheel driven by a clawker or driver, as shown and described, to give
motion to the cam or tappet actuating the series of levers which
operate to throw the thread carrier across the machine, motion may be
communicated by cog wheels or other suitable gearing.
By the application of apparatus as described extra threads may be
thrown across or partially across the machine, and worked into the
fabric in course of manufacture, without necessitating the stoppage of
any part of the machinery to give time for the throwing of the thread
or threads or reducing the speed of the ordinary bobbin net machine,
and various modifications of bobbin net fabric may be produced, or
fabrics may be made similar to those now produced in the ordinary
weaving loom.
Having thus described the nature of my Invention, and means which
I adopt in carrying the same into effect, I would have it understood

page_text: that I do not confine myself to the precise details shewn and described,
as the same may be varied without departing from the peculiar character
of my Invention; but what 1 do claim is, the actuating a thread
carrier or thread carriers to throw or carry an extra thread or extra
threads across or partially across bobbin net or twist lace machinery, or
machinery arranged and operating in a similar manner, by means of a
series of lovers, substantially as described.
In witness whereof, I, the said Henry Yates, have hereunto
set my hand and seal, this Twenty-eighth day of December, in
the year of our Lord One thousand eight hundred and sixty-
nine.
HENRY YATES. (L.S.)
