Improvements relating to Machinery for Spinning, Twisting, or
Doubling Cotton or other Fibrous Substances.
A communication by ANTON LORINSER, of Dietenheim, near Laupheim,
Wurtemberg, in the Empire of Germany, Manufacturer.
1, WILLIAM PHILLIPS THOMPSON, F.C.S., M.I.M.E., of the Agency for
Foreign Patent Solicitors, 6, Lord Street, Liverpool and 6 Bank Street,.
Manchester both in the County of Lancaster and 323 High Holborn in the
County of Middlesex, Civil Engineer, 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 :-
This invention relates to the suspension of the bobbins or cops in twisting and
similar machines, and by means of these improvements considerable advantages.
are obtained in comparison with the previous method of putting the same
on skewers.
The invention will be best understood by aid of the accompanying sheet of
illustrative drawings which shows the bobbins or cops suspended in a twisting
machine or frame.
Figure 1 being a front view, and
Figure 2 a side view of such frame.
It will be seen that, on these drawings, A represents the bobbins and a their
hooks by means of which they can be suspended. is a strip provided with catches.
or holes on which the bobbins are hung. B is the framing to which the strip bis
fastened, shows the threads passing from off the bobbins A. to the rollers C.
Instead of the bobbins being stuck with their heads in a bottom plate and the
threads being first carried upwards over a bar and from thence back again to the
thread guide rollers, they are suspended directly over the latter and fastened
to such bar by a ring attached to each of them in such a way that the threads run,
directly downwards."
By reason of the greater mobility in all directions of the bobbins thus obtained
as well as in consequence of the diminished friction of the thread or yarn, since
there is no occasion to lead the same over the upper bar, the thread can never
catch in the holder when the bobbin is run off as in the old method, as the holder
gives way in the opposite direction and the thread becomes free.
Any breakage of the thread even with the finer kinds of yarn is thereby entirely
avoided.
This is of very great importance when 3, 4 or even more threads are twisted.
when compared with the old method of putting the bobbins on spits or skewers as
tanglements could not be avoided and breakages of thread resulted. If, however,
with this new method of swinging in a suspended manner the bobbins, a breakage of
the thread should take place, such in no way affects the adjacent threads, as the
end of the thread running from the bobbin merely hangs straight down, whilst
with the present method of placing the bobbins on spits or skewers when a thread
breaks, the part of the same which is carried over the upper bar, may easily fall
back and become entangled or cause a breakage in the adjacent threads.
The bobbins too can be placed in position and hung more easily by this new
method, as it will not be necessary to adjust the twisting rollers, and run out
bobbins may be easily replaced by fresh ones, access by hand to the threads being
easily obtained, without having to fear a breakage of the same as in consequence
of the swinging suspension of the bobbins, the latter easily give way.
Further, the great waste of material hitherto entailed is avoided as the bobbin.
runs off totally, and there is also a not inconsiderable saving in operatives' wages.

page_text: This new method of suspending the bobbins or cops in a swinging manner may
also be used in connection with any old or new machine, and the cost of con-
struction comes somewhat cheaper than the former method of sticking them on
pegs or skewers.
Having now particularly described and ascertained the nature of the said inven-
tion, 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-
The improvements relating to machinery for spinning, twisting or doubling
cotton or other fibrous substances, which consist in arranging the bobbins or cops
loosely in a suspended and swinging manner, and in conducting the threads directly
downwards to the twisting rollers, substantially as hereinbefore described.
