COMPLETE SPECIFICATION
Improvements in the Manufacture of Silk Thread
1 CLAUDE KENNEDY MILLS, of 23 Southampton Buildings, in the County of
London, Patent Agent, do hereby declare the nature of this invention, a com-
munication to me from Messrs. Tresca Frères & Crè. of 8 Rue du Griffon, Lyons
in the Republic of France, Silk Manufacturers, and in what manner the same
Is to be performed to be particularly described and ascertained in and by the
following specification
-
In the Specification of Letters Patent dated April 5, 1892 No 6550 a new
product is claimed which has no twist and is obtained directly by two agglomerations
of the threads or fibres which compose it. The first agglomeration or doubling has
for its object to unite a certain number of filaments coming from the cocoons, and
to form therefrom ordinary untwisted threads of silk, and the second agglomeration
which takes place immediately after the first and on the same apparatus, has for its
object to unite several threads or filaments of this untwisted silk thread to form a
thread absolutely round and without any twist.
The mechanism which permits of agglomerating in succession first the filaments
or strands of the cocoons and secondly the untwisted threads of silk resulting there-
from, is a rubber of convex form turning rapidly around its axis, and on the surface
of which bear or press the filaments or threads to be agglomerated and which
filaments or threads are supported in gurdes
In the present application, is described an essential arrangement to be observed
and without which the product cannot attain to perfection
This arrangement consists
1. In establishing the contact of the threads with the rubber, on one side only of
its axis.
2 In causing this contact to commence as near as possible to the axis and in
causing it to finish near its circumference
Figure 1 of the accompanying drawing shows these conditions realised on the
thread a, composed of filaments or fibres a passing through the guides b and d
This thread moving in the direction indicated by the arrow, commences to touch
the rubber c, a little above its axis of rotation ay and leaves at near its circum-
ference The action of the rubber takes place in this case with a very slight speed,
Increasing progressively until its maximum is reached, which is very favorable to
the regular tounding of the thread and causes it to retain all its splidity
If the thrend were to pass in the direction indicated at b c d Figure 2, it would
be acted upon too suddenly an a very high speed, if it were to pass in the
direction b cd, it would be submitted to two actions in opposite directions. which
would destroy each other In both cases, the resultant thread would possess neither
the solidity, nor the regularity required for its employment.
The above conons may be fulfilled whatever be the form and position of the
rubbers by suitable arrangement of the guiffes b and d
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
dain, is
1 In the manufacture of untwisted silk thread of the character herein referred
to the essential arrangement consisting in effecting the contact of the thread on the
of rotation of this latter, and in canst

page_text: this contact to commence near to the axis where the speed of the rubber is very slow
and to finish near the circumference where its speed is at its maximum, substantially
as berein shown and described
2 The improvements in the manufacture of untwisted silk thread substantially
as herein shown and described
