PROVISIONAL SPECIFICATION.
Improvements in the Manufacture of Torchon Lace.
I, CHARLES WILFRED BIRKIN, of Broadway, in the Town and County of Not-
tingham, Lace Manufacturer, do hereby declare the nature of this invention
(which has been communicated to me from abroad by Mallère Frères, of Beau-
mont le Roger, Eure, France, Manufacturers,) to be as follows:-
This invention relates to the manufacture of lace upon machines of the class
described in the Specification No. 11411 of 1894.
In the ordinary method designs and effects are produced by causing a single
thread to traverse (at an angle to the threads making the net) to and fro com-
pletely across the space to be covered by the design or effect.
This process is slow for this bobbin carrying the thread has to traverse a very
long distance compared with the length of lace produced and the bobbins
making the net have consequently to remain stationary at intervals waiting
for it.
According to this invention the speed of production is greatly increased by
using two or more threads working simultaneously to produce the design or
effect. As before each thread moves to and fro across the whole width of the
design or effect but in place of their convolutions being close together as with
the single thread, their convolutions alternate the one with the other, the
threads crossing each other at convenient points. Or the threads in place of
traversing the whole width of the design or effect may meet and interlock with
each other at about the middle and then return,

COMPLETE SPECIFICATION.
Improvements in the Manufacture of Torchon Lace.
I, CHARLES WILFRED BIRKIN. of Broadway, in the Town and County of Not-
tingham, Lace Manufacturer, do hereby declare the nature of this invention
(which has been communicated to me from abroad by Malhère Frères, of Beau-
mont le Roger, Eure, France. Manufacturers,) and in what manner the same is
to be performed to be particularly described and ascertained in and by the
following statement :-
This invention relates to the manufacture of lace upon machines of the class
described in the Specification No. 11411 of 1894.
In the ordinary method designs and effects are produced by causing a single

page_text: thread to traverse (at an angle to the threads making the net) to and fro com-
pletely across the space to be covered by the design or effect.
This process is slow for this bobbin carrying the thread has to traverse a very
long distance compared with the length of lace produced and the bobbins
making the net have consequently to remain stationary at intervals waiting
for it.
According to this invention the speed of production is greatly increased by
using two or more threads working simultaneously to produce the design or
effect. As before each thread moves to and fro across the whole width of the
design or effect but in place of their convolutions being close together as with
the single thread, their convolutions alternate the one with the other, the
threads crossing each other at convenient points. Or the threads in place of
traversing the whole width of the design or effect may meet and interlock with
each other at about the middle and then return.
Figure 1 is a diagram showing the old method of manufacture.
Figure 2 is a diagram showing the improved method and Figure 3 shows the
modification.
a are the threads producing the net and are the thread or threads producing
the design.
In place of only employing two threads b as shown in Figures 2 and 3 there
may be three or more.
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 what
I claim is: --
1. In the manufacture of lace on machines of the class referred to producing
the design or effect by causing two or more threads to traverse simultaneously
across the space to be covered by the design or effect at an angle to the threads
making the net.
2. The manufacture of lace substantially as described and illustrated in the
drawings.
