We JAMES SMITH and JOHN SMITH of the Firm of E. Smith and Sons, De Ligne
Works, Radford, Nottingham, Lace Manufacturers, do hereby declare the nature of
this invention to be as follows:-
Our improvements consist in producing twist lace fabrics, either nets or breadthis
having a plain ground or a spotted ground capable of being produced on double tier
twist lace machines either of the rolling locker principle, or the double locker principle,
by the following means.
We employ a warp supplied from one or more beams, the said warp being of any
required colour, the bobbin threads in the whole of the carriages we supply with
threads of divers colours placed alternately in groups of equal number. By such
means we are enabled to produce plain or spotted nets or breadthis, having diagonal
squares, checks or plaids, or combinations of diagonal squares, checks, or plaids of
divers colours, alternately, by traversing the front tier of carriages and bobbins from
the right to the left, or from the left to the right, the back tier of carriages being
traversed the reverse way, the crossings of the bobbin threads producing the required
patterns.

Improvements in Twist Lace Fabrics.
Wo JAMES SMITH and JOHN SMITH, of the Firm of E. Smith and Sons, De Ligne
Works, Radford, Nottingham, Lace Manufacturers, 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 :-
Our improvements consist in producing novel effects on twist lace fabrics, either
nets or breadths having a plain ground or a spotted ground, capable of being produced
on double tier twist lace machines, either of the rolling locker, or double locker
principle or any other variety of machine in which the bobbins and carriages are
traversed to produce twist lace by the following means.
We employ a warp of any required colour or colours and divide the width of the
machine into groups of carriages and bobbins carrying threads of divers colours, the
number of bobbin threads of each colour varying according to the size of square, or
check required. Each group we may divide into two or more divisions (not necessarily
of equal numbers) according to the number of colours employed, then by placing the
carriages, and bobbins with their threads in the machine in whole groups or divided
groups of colours alternately, so that there may be an equal number of groups of
each colour, we are enabled to produce diagonal squares, checks or plaids, or
combinations of diagonal squares or checks of divers colours alternately by traversing
the front tier of carriages and bobbins with their threads from right to left or from
left to right the back tier of carriages, bobbins and threads being traversed the
reverse way, the crossings of the coloured bobbin threads producing the required
patterns.
Having now particularly described and ascertained the nature of our said
Invention, and in what manner the same is to be performed, we declare that what
we claim is —
The production on plain or spotted traversed twist lace of diagonal squares, checks
or plaids, or combinations of diagonal squares, or checks of divers colours alternately,
substantially as described in the foregoing specification.
