4. Increasing its contact more or less immediate with the thread; and
5. Increasing the damping surface by the aid of grooves arranged in any
convenient and suitable manner, whereby a larger quantity of the liquid takes part
in the absorption.
These combinations, it is worthy of remark, enable me, by means of one or the
other or of all, to graduate the quantity of liquid brought into contact with the
thread, exactly according to requirement.
In case all these means prove insufficient to give a satisfactory result, I
supplement the rotary movement of the cylinder by the addition of a longi-
tudinally reciprocating movement in the direction of the cylinder-axis, in such
a manner as to increase still more the damping, during this movement; by this
means there would be the further advantage of more neatly ensuring the folding
in and adherence of the fibres of the thread, since the latter, in addition to the
wetting and preparation would further be in some sort moved or upset. Finally the
approximation of the fibres and the removal of the excess liquid absorbed, prior to
the time when the thread is wound on the spindles, is ensured by the aid of nippers,
acting on plugs of cloth, felt linen, rubber or other the like material, through which
the thread passes.
These pincers rotate on a pivot longitudinally placed in the direction of their
faces, and located on the thread-guide plate; while in operation they receive an
oscillating movement from the thread served by them.
The adoption of means to damp the material to be spun at a temperature
different from that of its surroundings; to cause the thread to approach to or
recede from, the surface of the wetting fluid, according to requirement; to
augment or diminish the speed of rotation of the rolling surface; and, in fine,
with this, all the arrangements for graduating the wetting, to increase the
damping, to remove the surface liquid, as well as to regulate the surface-level
of the liquid in the vat-all these are quite new.

page_text: It is in virtue of these improvements that the process is rendered applicable
to spinning-machines, and it is for that reason that the applicant reserves to
himself the exclusive property of the invention, which comprises also the
improvements effected in the means of preparing the thread or cord.
By way of example simply, and the better to define the principle of the invention,
while reserving all rights of industrial property in the use of this process and in the
use of the related machines, of no matter what form, I will now give the description
of one of the modes of application and use of this new system with reference to the
accompanying drawings wherein
Fig. 1 is a side elevation of apparatus constructed according to this invention,
partly broken away to illustrate details of its construction.
Fig. 2 is a vertical section on the line 2, 2 of Fig. 1.
Fig. 3 is a vertical section on the line 3, 3 of Fig. 1.
Fig. 4 is a plan of the bearing shown in elevation in Fig. 3.
Fig. 5 is a view of a detail of Fig. 3, drawn to a larger scale than that of the
last-named figure.
Fig. 6 is a view of the parts shown in Fig. 5, but at right angles to the position
in which they appear in the latter.
Fig. 7 is an elevation of a thread-clip H hereinafter again referred to.
Fig. 8 is a plan of a thread-guide plate also hereinafter again referred to.
Fig. 9 is a diagram illustrating the application of my invention to a spinning-
machine.
Like letters indicate like parts throughout the drawings.
A is a tube or cylinder in the nature of a horizontal rotary shaft, set in motion
in bearings B by a force taken from some driving portion of say a spinning
machine. On this are secured a series of drums or rings, cylindrical in shape a, b,
c, d, e, f, g, h, and of any kind, smooth, corrugated or ribbed, but hollow and com-
municating by perforations A' made for the purpose in the walls of the tube A
with the interior cavity of the latter, as shown in the cross section Fig. 2. The
number of such rings or drums should be the same as that of the separate ends
of threads on the spinning machine.
In the cavity of the above-named tube A or rotary shaft steam, is if necessary,
injected to warm both shaft and drums beneath the shaft, at a distance suitable
to the size of the drums which are dipped into it, is a trough G containing the
liquid intended for the damping or preparation of the threads, which are fed
through the apparatus. The liquid is so supplied to the trough G that its level
may be regulated in relation to the drums, and raised or lowered, so as to increase
or diminish the depth to which the said drums dip into it; this regulation of the
liquid may be effected by any convenient means.
The threads slide, as shown by the thread C in Fig. 3 over the drums or
rings a,
b&c., (the form of which as stated and as shown in the drawings, may be
varied) and, by the aid of regulating screws B' B the bearings B and consequently
the shaft A can be so adjusted that the said threads are caused to adhere
more or less closely to the surface of the drums or rings round which they pass.
The thread passes on its way from the drums through a thread clip H constituted
as follows (see Fig. 7)
On a pivot I let into the thread-guide plate K shown separately in plan in
Fig. 5 are mounted two jaws L, only one of which is shown in the drawings,
pressed together by a small spring N; between these jaws are held small pieces of
cloth, or felt, or equivalent, between which the thread passes, in such manner that
the entire clip or nippers, while pressing on the thread is in continual vibration and
oscillates on its pivot, owing to the passage of the thread.
The thread issuing from between this clip has its moisture wiped from it and
passes downward by way of the thread-guide plate K to the spindle to be wound
on the bobbin.
Thus it will be seen that the thread does not in any way pass through the
trough G which has no other use than to act as a "drinking trough" for the

page_text: discs a, b, &c. for the latter to take up the requisite quantity of fluid, to be com-
municated or imparted to the thread C passing over the disc, the position of
which is controlled by the screw B2 so that the thread may be saturated with
liquid or may absorb and take up more or less of the same and afterwards pass to
grippers H which wipe or remove from it the excess of the liquid and allow of its
being rolled on the bobbin.
The accompanying drawing shows only one of several methods of applying the
invention which may be varied in numerous ways, without any departure from its
principle or scope.
This process is applicable in the following cases;—
I. In application to existing spinning machinery:
II. For use in the preparation of sewing-thread or cord, as a distinct machine,
and not only as an adjunct to other thread-preparing apparatus.
Having now particularly described and ascertained the nature of the said inven-
tion, and in what manner the same is to be performed, 1 declare that what 1
claim is ;-
1. A new method of wetting and preparing threads and cords of all kinds of
vegetable fibre as well directly as in the spinning thereof.
2. The application of this new method to all spinning machinery.
3. The devices for regulating the wetting and preparation of the thread
according to the circumstances and conditions of the case the requirements the
custom and the nature of the thread.
4. The subsidiary devices in case of need to increase and remove the surplus of
the wetting and preparation of the threads as well as to attach the loose fibres to
the threads while ensuring their folding-in and adherence.
Finally the entire process with its elements and its adjuncts for the purposes set
forth substantially as indicated and described in this Specification.
