Improvements in Reeds for Looms.
I, EDMOND MAURICE BERGNER of 19, Rue d'Uzès, Paris, France,
Manufacturer, 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 an improved reed applicable to all kinds of looms
and having for object to produce the entwinement together of two or more
warp threads.
Reference is to be had to the accompanying drawings forming part of this
specification which illustrate my improved device by way of example only,
Figure 1 being a partial front elevation and Figure 2 a cross-section of
the reed.
Figures 3-4 5 6 and 7 are detail views shewing in elevation and section the
action of the reed for effecting the twisting of the threads.
The same letters of reference denote like parts in all the figures.
The dents a of the improved reed have central holes b, which may be formed by
drilling, wherein perforated spherical thread guides, formed by beads c, are
imprisoned one between each two adjacent dents a, the beads being of slightly
larger diameter than the space between the dents and capable of rotating about
their axes and being all at the same height. Through each bead is passed the
one d of the two warp threads, the other warp thread e passing between the dents
of the reed either above or below the beads c. The beads c may be made of metal,
glass, or other suitable material. The dents a are spaced according to the nature
of the work to be done and are fixed to top and bottom bars f
The reed thus constructed is mounted in a batten capable of moving both up
and down and laterally. Thus arranged, supposing the warp threads to be in the
position shewn in Figure 3, the winding of the threads d which pass through the
beads c about the free threads e may be effected by moving the batten to the left,
then lowering it as in Figures 4 and 5, the reed being then returned to the right
and afterwards raised as in Figures 6 and 7, so as to be returned to its initial
position. This operation is performed as many times as it is desired to make turns
of threads d about threads e. To untwist the threads the operation is performed
in the inverse direction.
In order that the threads shall not remain twisted at the side opposite the
operator it is necessary that as many turns should be made to the right as to the
left. For example, if it is required to make a fabric presenting meshes of a certain
size, these meshes would be produced by causing the threads to make a certain
number of turns, four turns for instance, but it is then necessary that the fabric.
which follows each mesh should contain four shoots of weft so as to enable the
warp threads to be brought back to their initial position.
In combination with the improved reed is another reed of the count required for
making the ground or middle portion of the fabric, the twisted warps being
designed for making a border to the fabric.
It is to be understood that my improved reed which enables a new mode of
intertwining of the threads to be carried into effect may be applied to all kinds of
looms without altering the mechanism of the loom, for producing all kinds of fabrics
whether light or heavy.

page_text: Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed I declare that what I
claim is :-
1. The herein described reed for looms whereby, to effect the twining together
of warp threads, said reed consisting of a series of equally spaced apertured dents
in combination with perforated spherical warp thread guides imprisoned in the
apertures of the dents so as, whilst guiding or retaining the warp threads which
pass through them, they may turn freely and give passage between them and the
dents to the other warp threads passing between the same dents as specified.
2. The herein described reed for looms whereby to effect the twining together
of warp threads, said reed consisting of a series of equally spaced apertured dents
in combination with perforated spherical warp thread guides imprisoned in the
apertures of the dents so as to guide or retain the one set of threads and give
passage to the others as described, the reed being so mounted as to be capable of
receiving vertical and lateral motion for the purpose of effecting the entwining
of the threads in the manner specified.
