Improvements in or connected with Warp-looms.
'FICE CE
Communicated from abroad by CARL KREISSIG, LOUIS SONNTAG, Junior, and
OTTOMAR HARTIG, of the City of Gruna, in the Kingdom of Saxony, German
Empire, Gentlemen.
I, CHRISTEN REES BONNE, of 57 & 58, Chancery Lane, in the City of London,
Patent Agent, do hereby declare the nature of this invention, and in what manner
it is to be performed, to be as follows:
:-
In the Patent Specification Number 9470-1889 a method has been described of
producing false meshes in warp looms by means of latch needles, and the object
of the present invention is now to show how "false meshes can be produced in
warp looms worked with ordinary needles.
"
In the Specification above referred to it has been fully explained how it requires
almost the same amount of time to produce a row of false meshes as it does to
produce a row of regular ones, but according to our present invention we produce
the false meshes simultaneously with the ordinary meshes.
From the drawings herewith and the following Specification our method will be
readily understood.
When a row of meshes (w) Figs. (1 and 2) is finished, then the sinkers (p) Fig. (2),
drop, and with their hooks pull the goods on the needles backwards, thus locking
in. As soon as the sinkers () have got behind hook points n' (Fig. 3) then warp
guide (1), which has during the operation been pushed towards and underneath the
loom needles, makes a loop (e) over a loom needle, that is to say each thread (a) of
a mesh of the preceding row Figures (1, 2 and 3) is raised as shewn in Fig. (3),
laid over needles (n¹) and again lowered to (b). Hereupon the warp guide (1)
moves away under a loom needle (n Fig. 4) and each thread passes from (b) to (c)
and finally, while sinkers (p) have gone quite back on the needles, (Fig. 5) the
warp guide (1) is once more raised and pushed over a loom needle and a thread
from each passes upwards by (c) (Fig. 5) forms loop (e¹) and sinks down again
to (d). Each loom needle has thus received two loops (e) and (e), which, as shewn
in Fig. 5, lie a little away from each other, because the thread from (e) passes
downwards over loom needle (n¹) to (b) and across to (c) Fig. (5) in order to
form (el) on (n) whereby loop (e) remains attached to the sinker, while the
thread from (e) passes direct through the eye in needle, and consequently (e¹) is
drawn somewhat forward.
The sinkers now get in front (Fig. 6) pushing meshes (w) and the first loops (e)
forward, the warp guide (1) moving simultaneously outward from the row of
needles thus tightening the threads, which also pull the second loops (e¹) forward
into the needle hooks.
As soon as the hook points are between (e) and (e¹) (Fig. 6) then presser (ƒ)
comes down, so that sinkers (p) (Fig. 7) push firstly the loops (e) and then, when
raised, (Fig. 8) also the old meshes (w) on to the hooks, while loops (e¹) remain
hanging on the hooks.
The first loops are thus brought together with the old meshes (w), and form blind
meshes as (e) in Fig. (1). The presser (f) is thereupon removed and sinkers (p)
strike goods (w) with blind meshes (e) Fig. (9) from off the needles and in this way
is formed the new row of meshes as (el) Fig. 1.
The blind meshes for the preceding row have thus been formed during the
formation of this row of meshes without loss of time and the process is repeated
constantly

page_text: Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is:
The method of producing blind meshes on warp looms by the warp guide laying
its thread twice over the loom needles while a row of meshes is locked in, the first
time (e Fig. 3) when the sinkers have arrived a short way behind the needle hooks
and the second time (e¹ Fig. 5) during the further backward movement of sinkers
substantially in the manner as described and as shewn in the drawings.
