Improvements in the Manufacture or Production of Lace Fabrics.
I JAMES YATE JOHNSON of 47 Lincolns Inn Fields in the County of Middlesex
Gentleman do hereby declare the nature of this invention (which has been
communicated to me from abroad by Alfred Julien Sagot of Calais in the Republic
of France Lace Manufacturer) 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 a new lace (net double gauge) and to the means for
producing the same as hereinafter described. It consists in obtaining a ground
or net resembling the ground or net made with one mesh to each carriage and
known as Endsor ground or "crève cœur" ground this ground being employed in
Spanish, Chantilly and veil lace usually manufactured with the lever loom.
Figures 1 and 2 of the annexed drawing illustrate by way of example designs
for different crossings of the threads in a fabric according to this invention. In
Figures 1 and 2 the straight vertical lines made with alternate dots and dashes
represent the shuttle or bobbin threads whilst the thick lines and the fine lines
passing from left to right and vice versa represent the warp or beam threads.
These designs correspond with the following drafts.

page_text: of such meshes being composed of three warp threads and without a bobbin
thread.
This mesh made with three warp threads is imitated upon in the sense that one
of these threads forms the straight part of the mesh whilst the other two threads
one passing to the right hand and one to the left hand form the transverse part of
the ground.
The second mesh is made with one bobbin thread and one or two warp threads
according to the size required.
The new lace net made according to this invention presents the appearance of a
net or ground made with a single mesh to each carriage and is distinguished from
all other or ordinary lace net double gauge by its resemblance to Endsor or
"crève-cour" lace.
At the same time and by means of the same process there are formed according
to this invention meshes of different dimensions or large and small meshes combined
together so as to obtain open work effect in a partial or continuous manner
according to the kind or richness of the lace to be imitated.
According to another part of this invention there is produced at the same time
as the new foundation and also by the combination of the aforesaid warp threads
with one another, various effects of lace fining and which are employed with or
without gimp. With this object a regular or irregular crossing of the warp threads
of any suitable closeness is produced in any part of the web simultaneously with
the production of the lace ground or net hereinbefore described and producing in
combination with the latter an effect of warp lace fining.
Having now particularly described and ascertained the nature of the said
invention and in what manner the same is to be performed declare that
what I claim is :-
1. As a new article of manufacture the lace net double gauge produced
substantially as hereinbefore described with reference to the accompanying
drawings.
2. In a lace net or ground the mesh composed of three warp threads and made
without a bobbin thread, by manipulating the warp threads and intertwining or
combining them one with one another, the said mesh having on ca 1 side of it a
mesh made with the bobbin threads and obtained in the mann and for the
purpose substantially as hereinbefore set forth with reference to thiccompanying
drawings.
3. In a lace net or ground of the class referred to in the prece
production of meshes of different sizes or large and small meshe sco.
for the purpose substantially as hereinbefore set forth.
