page_text: I, WILLIAM HENRY SMITH-GOARD, of Calais, in the Republic of France, Manu-
facturer, 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:-
-
This invention relates to improvements in the lace machine for making relief
effects on the threads running between the ties and in which it is only necessary
to have one bobbin thread with the warps.
The spots are made by the bobbin threads and are either between or on the ties
formed by the meeting of the threads. The novelty is that the spots can be made
where there is only one bobbin thread employed in conjunction with the warp
threads, whereas it has hitherto always required at least two bobbin threads.
To make it more clear the accompanying drawings are annexed.
Fig. 1. Shows various examples of spots as mentioned above.
Fig. 2. Transverse section of the inside of a lace machine showing the position
of appliances for this improvement.
Fig. 3. Longitudinal elevation of a part of the appliance introduced into this
machine.
Between the two rows of combs A and A¹ of an ordinary machine and below
them are placed the metallic bars 13 to which are fixed the blades which pass
from the bars B upwards between the carriages and rest on the work bar C.,
The number of blades b used in the bars B will vary according to the distance
required between the spots, there may be one to each carriage or one to two
carriages or one to three or to every fourth and at greater distances if required
by the design, the whole of the blades forming a sort of comb through which the
carriages 1) pass as they travel from the front to the back comb bars and vice versa;
carrying the bobbin threads which with the warp threads form the mesh or
groundwork.
The thickness of the blades b is suited to the gauge of the machine and the space
between the carriages D, and the width of the blades according to the importance
of spot required.
The bars B in which the blades are fixed are worked by the jacquard and in
such a way as to make the bobbin threads work round them, and the twists are
successively drawn by the points PP¹ and accumulate the material which forms
the spot at the point X, the racking up being stopped while the twists are accumu-

page_text: lating for more or less motions according to the size of spot required, the warp
threads are used with the bobbin threads to form the groundwork, and to hold in
place the spots when made and leaving the top of the blades.
These blades have been used in the lace machine but have always been stationary,
whereas in this invention the blades are worked by the jacquard in such a way
that the bobbin threads twist round them, and by this means produce a spot with
the bobbin threads instead of the warp threads.
The novelty consists in the jacquarding of the blades 13 which takes the bobbin
threads and twists them round the blades to produce raised effects in the lace at
any point either at intersections or between them with the bobbin threads.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed, declare that what I
claim is:-
1. In a lace machine the placing of moveable blades between the comb bars
worked from right to left, or from left to right, round which the bobbin threads
are twisted to produce raised work in the lace, on or between the ties by means of
one bobbin thread (or more if desirable) for the pattern, substantially as described.
2. In a lace machine the placing of the blades in several bars which are
between and below the combs, the same being worked by the jacquard or a similar
appliance to give the necessary motions to twist the bobbin threads to produce
raised effects, substantially as described.
3. In a lace machine the apparatus for forming spots constructed and arranged
substantially as described.
