I, HENRY HARRIS LAKE, of the firm of Haseltine Lake & Co, Patent Agents
Southampton Buildings, in the County of Middlesex 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:-
"
The present invention relates to a method of enabling power-looms to be
operated uninterruptedly so as to produce pieces of fabric of unlimited length, and
at the same time to avoid the necessity for warping and beaming the warp. By
dispensing with the latter operation, which in the method of working heretofore
adopted has taken up much time, a great saving in labour and wages is effected.
The improved method is essentially characterized by the fact that, on the one
hand, the warp threads are continuously introduced into the loom, directly from
spools or bobbins, the necessary tension being applied by apparatus arranged
between the bobbins and the loom; and, on the other hand, the fabric produced on
the loom is continuously conducted away, this being effected by means of special
winding apparatus placed before the loom.
The said invention is carried into practice in the manner, and with apparatus,
hereinafter described.
In the accompanying drawing
Figure 1 is a vertical section, and
Figure 2 is a plan of the said apparatus.
A is the frame carrying the bobbins, B the tension-apparatus, C the loom, and
D the winding-apparatus.
The frame A carries the bobbins a in several rows above and beside one another,
which bobbins are mounted on spindles, as in a warping frame, upon which they
turn when the thread is unwound.
The threads unwound from the bobbins first pass through suitably arranged
separators or openers b and c into the tension apparatus B.
"
The tension apparatus consists of the guide-rollers d, d, e and f and the pairs of
pressure rollers g and h which are all supported in a suitable frame so that they
can.turn...

page_text: The warp-threads from the bobbins pass between the rollers d, d, then between
the pressure-rollers g, g provided with fine longitudinal grooves, then around the
guide-roller e, then between the second pair of pressure-rollers h, and finally
around the guide-roller f into the loom C.
Between the pairs of rollers d and g, and also between the rollers fand the loom,
cross bars i are advantageously inserted.
The upper rollers of the pairs of rollers g and h bear upon the lower rollers, and
their journals are supported in bearings which are connected by links with the
loaded levers m having their fulcrums at n
The position of the weights o upon the levers n determines the pressure with
which the upper rollers g and h act against the lower rollers.
Near each of the rollers g and his arranged a shaft p which is provided at each
end with a lifting lug p and a hand lever p². Each lower roller g and his
provided with a crank q. Now, should it happen that one of the threads passing
through the tension apparatus B is broken at a point between the rollers d and the
pressure rollers h, the upper pressure roller g is raised by the levers m through the
medium of the lifting lugs p'; the thread can then be tied and put back in its
place, whilst one end of the broken thread remains stretched by the pair of
pressure-rollers h.
When a thread breaks between the rollers g and the loom, the
upper pressure-roller h is raised by the lifting lugs p¹, the thread is then tied and
put in again, whilst the other end of the torn thread remains stretched by the pair
of rollers g. If, by the breakage of a thread in the loom, it becomes necessary to
draw back the warp threads, this is effected by turning the cranks q.
The warp-threads coming from the tension apparatus are woven in the usual
manner, in the loom C. Whilst, however, in the usual mode of weaving the
finished fabric is wound upon the cloth-beam situated in the lower part of the
loom; the fabric in this case passes from the breast beam r around a transporting-
rollers provided with fine needles, the guide-roller t, a guide roller situated in
the lower part of the loom below the stand for the weaver, and a roller v to the
cloth-roller w of the winding apparatus D. The roller wis driven, independently
of the loom, by a pulley and strap from the driving mechanism.
The winding apparatus is advantageously provided with measuring apparatus
(for instance as at x in the drawing) which indicates the length of the fabric
wound upon the roller wand rises automatically with the increasing diameter of
the roller w.
As soon as the thread of a bobbin a is exhausted, the end of said thread is tied
to the end of the thread of a new bobbin which is put in the frame A in the place
of the empty bobbin.
In order to perceive when the thread of a bobbin is exhausted, the following
arrangement has been made :-:
1
In spooling the thread upon the bobbins, a certain quantity of a differently
coloured thread is spooled-on first, the end of this thread being.connected with the
commencement of the required thread. If, for example, white yarn is to be wound
upon a spool or bobbin, a piece of black yarn is first spooled-on, its end being
connected with the white yarn; the white yarn is then spooled-on. Now, when
the white thread is used up, black thread (as at z Figure 2) will appear indicating
to the operator that the white thread is used and that a new bobbin must be put
In this manner the feed of the warp threads is made continuous.
on,
Having now particularly described and ascertained the nature of my said
Invention, and in what manner the same is to be performed, as communicated to
me by my foreign correspondent, I declare that what I claim is :-
First. The above described method or manner of providing for the uninterrupted
working of a power-loom and the manufacture of pieces of fabric of unlimited
length, and enabling the warping and beaming of the warp to be dispensed with,
which method consists in taking the warp-threads for the fabric directly from
the bobbins, placing an adjustable tension-apparatus between the bobbins and the

page_text: loom, and a winding-apparatus in front of the loom, which winding apparatus,
being driven independently of the said loom, winds the fabric continuously upon a
roller as it is manufactured.
Second. In the method claimed in the preceding claiming clause the employment
of a tension-apparatus, consisting of the guide-rollers d d, e and f and the pairs of
pressure-rollers g and h, the upper rollers of which pairs can be variably loaded
and also lifted from the lower rollers in order to enable, in case a thread should
break, the said thread to be tied and replaced.
