Machine for Untwisting and Ploking Ropes of Curled Fibre.
I, SAMUEL ALBERT FLOWER of No. 79 Clinton Avenue in the City of
Newark, in the State of New Jersey, United States of America, Manufacturer, 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:--
My invention consists of improved apparatus for untwisting and picking roped
and curled animal and vegetable fibres for upholstery and other purposes, reference
being made to the accompanying drawings in which :-
Fig. 1, is partly a side elevation and partly a longitudinal sectional elevation of
my improved machine.
Fig. 2, is a plan view of said machine in part.
In this invention I have combined one or more drawing and twisting heads
with feed rolls and a picker so that by running the said drawing and twisting
heads in the direction for untwisting the ropes, and then delivering the untwisted
ropes from each head to the picker the fibres may be rapidly picked apart for
upholstery use.
A represents drawing and twisting heads which may be of any common or
approved form of construction containing feed rolls for holding the ropes for
untwisting, and being geared for feeding the ropes, said drawing and twisting
heads preferably arranged side by side in a horizontal plane. b, represents feed
rolls adapted to feed a rope c, of curled fibres to each head; da pair of feed rolls
to receive the untwisted ropes from the drawing and twisting heads, and e a picker
cylinder for receiving the ropes from feed rolls d, and picking them apart.
findicates a doffer for discharging the picked fibres from the picker.
As indicated by the arrow a, it will be seen that the drawing and twisting heads
are made to rotate reversely to the twists of the ropes, so that said ropes being
held by the feed rolls b, against rotation and being held by the rolls h of the
drawing and twisting heads for turning, and also for feeding forward, they will be
untwisted between these two pairs of rolls, and then being delivered to the picker
in the untwisted condition may be readily picked apart.
The feed rolls, drawing and twisting heads, and the picker may be driven in any
approved way as usual in such machines. In this example I have represented a
belt i, as driving the front drawing and twisting head from an overhead shaft ; and
other belts kl for driving the feed rolls from said shaft. Other like overhead shafts
may be provided for driving the other drawing and twisting heads.
The untwisted ropes may of course be delivered from the feed rolls to other
picking devices or they may be delivered to receivers of any kind, to be retained
for subsequent picking, and the untwisted ropes may be delivered directly from the
rolls of the drawing and twisting head to the picker or other receiver with good
results, but in such case the said drawing and twisting head should have a funnel
shaped terminal.
The drawing rolls h have their journals suitably mounted in the curved slots n,
whereby they may be adjusted for larger or smaller ropes circumferentially to
the axis o, from which they are driven by the spur wheels P: each independently
of the other, for which bevel wheels are provided on opposite sides of the head
respectively, which gear with the bevel rim of the spur wheel & turning freely on
the hollow shaft u, of the drawing and twisting head, the wheel t being turned by

page_text: aspur wheel on the shaft w, to which motion is imparted by the spur wheel
geared with the spur wheel y on the shaft u, but this construction and arrangement
of the gearing of the drawing and twisting head is not included as a part of the
invention claimed in this case.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is :-
1. The combination of untwisting apparatus for roped fibres consisting of one or
more drawing and twisting heads, feed rolls for delivering the roped fibres thereto
and holding them for untwisting, and feed rolls for receiving and discharging the
untwisted ropes from the drawing and twisting heads substantially as described.
2. The combination of untwisting apparatus for roped fibres consisting of one or
more drawing and twisting heads having rolls for holding the ropes for untwisting,
and being geared for feeding them along, feed rolls 6 for delivering the roped fibres
thereto, and holding them for untwisting, feed rolls d, for receiving the untwisted
ropes from the drawing and twisting heads, and a picker for picking the fibres
apart substantially as described.
