Improvements in Machines for Doubling and Winding Yarns and
Threads.
I HERBERT JOHN HADDAN, of the Firm of Herbert Haddan and Co., of
18 Buckingham Street, Strand, W.C. London, Consulting Engineer, do hereby
declare the nature of this invention, a communication to me from abroad by
Paul Lemaître-Bonduelle, of Rue Nationale 284, Lille, in the Republic of France,
Manufacturer 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 improvements in machinery for doubling and winding
yarns and threads and more particularly to the loose entwining of textile threads
with metallic ones for the purpose of obtaining a composite textile and metallic
thread for use in weaving.
The textile threads are first placed parallel with the metallic threads by winding
them off together from their respective bobbins onto a single bobbin so that they
lie on this bobbin side by side but not twisted. The threads thus prepared are
then twisted together and wound in cops on a machine as hereinafter described
which may consist of an ordinary winding machine with the necessary modifications
required by this process.
In the annexed drawings
66
Figs. 1 and 2 are respectively front and side views of a Hacking" winding
machine having the improvements adapted to it.
Fig. 3 is a longitudinal section of one of the bobbins b on which the threads have
been previously wound as above described, this bobbin being shown on a larger
scale.
The bobbins bare shaped so that the central portion forms a cylinder b¹ bounded
at the upper end by a rounded flange and at the lower end by a larger flange or
base plate & flat on its upper face and rounded on its lower face and provided with
an annular groove. for the reception of the cord C by which it is driven from the
central drum T. The bobbins b are made to revolve on a row of pins fixed vertically
on the framework of the machine and the two parallel threads R are led upward
from each bobbin through an eye h and thence to the arm g which guides the
threads as they are wound on the cop d in the usual conical manner.
The cop
tubes d are supported on stationary fixed pins and revolve thereon by the friction
of the conical disks K against the conical part of the cop. These conical disks
support the cops and as the latter lengthen under the progress of the winding the
pressure of the disks K, the axis of which remains stationary, gradually forces the
cop upward, maintaining the winding position at the same place. When the cop is
full this upward movement by the disks K will have lifted the cops off the ends
of the spindles or fixed pins and the cop will be thrown out side ways and will fall
from under its upper pivot d' which is carried by a bearing block suitably guided
and rests upon the pivot bearing at the upper end of the cop tube. Each cop is
thus automatically thrown out when full and is replaced by another cop tube by
the attendant workman who places the pivotal bearing of the cop tube under the
upper pivot pushing up the bearing block and allowing the cop tube to pass
onto the end of the fixed pin d and then allowing the tube to sink on the latter
and the upper bearing to fall with it until it comes to rest at the bottom, and the
winding having formed a cone permits the disk K to recommence its raising function,
and the before mentioned process is repeated.
The disks K are mounted on the shaft y which is connected by belt F to the
shaft of the drum T; the pulleys p p carry this belt. The drum T also drives
the bobbins 6 by the belt C. The shaft of the drum T is driven by power with

page_text: intervention of the usual speed varying gear necessary in winding cops conically.
The arm g which guides the twisted threads as they are wound on the cop is moved
up and down upon and with the oscillating movement of the shaft by the arm /
on said shaft with its wheel g' running on the heart cam z.
Having now particularly described and ascertained the nature of this said inven-
tion and in what manner the same is to be performed I declare that what I
claim is;
1. Improvement in doubling and winding machines, consisting in the drum T
serving to set in motion the bobbins by means of a continuous cord or similar
device, such movement producing the twining or twisting together of two or more
textile and metallic threads.
2. The herein described shape given to the bobbins b.
3. The combination of the above improvements with existing winding machinery
of the kind described, substantially as described and illustrated and for the purpose
set forth.
