declare the nature of this invention to be as follows:-
This invention relates to the class of twisting frames in which tho yarns to be
twisted together are drawn into the flyer by hauling pulleys carried by the flyer.
The flyers hitherto employed for such purpose are "closed" Byers that is to say the
flyer arms are connected at both ends and provided with bearings or supports at each
end of their axis.
According to this my said invention I employ a combination of open legged flyer
and hauling pulleys the flyer having a special construction of head or supporting and
driving tube.
The open legged flyer carries the hauling pulleys inside and the extremities of the
legs are left open so that the bobbin traverses freely beyond the ends of the legs or
curls of the flyer.
The flyer and its carrying and driving socket are made in two or more pieces
attached to each other the one consisting of the flyer proper and the other of a tube
fastened to the top of the flyer forming a supporting tube or socket for the flyer of
sufficient length to give steadiness to it and to afford space for the requisite bearings
and space for the pulley employed for driving the flyer.
The bobbins may be carried upon sockets that revolve upon studs which are fixed
in the builder or traversing rail and which are caused to move or traverse concentrically
with the flyer.
The requisite drag to cause the bobbins to take up the twisted yarns is applied to
the socket that carries the bobbin which is temporarily connected to the socket.
By the combination of specially constructed open flyer and hauling pulleys a more
convenient working frame is obtained, the doffing operation is simplified, the weight
of the flyer is reduced, a higher speed, when desired, can be obtained, than is
practicable with the flyer, supported at both ends, and with the mechanism for
traversing the yarn on the bobbin inside the flyer as heretofore.

page_text: I, ABRAM COMBE of Falls Foundry, Belfast, Ireland, Machinist 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 class of twisting frames in which the yarns to be
twisted together are drawn into the flyer by hauling pulleys carried by the flyer..
Heretofore the flyers employed for such purpose were "closed" flyers that is to say
the flyer-arms-were-connected-at both ends and provided-with-boarings-or-supports at
each end of their axis.
According to this my said invention I employ a combination of open legged flyer
and hauling pulleys the flyer having a special construction of head or supporting and
driving tube, this combination will be understood by referring to the drawings here-
with-in conjunction-with-the-following.description.
Such being the nature and object of this my said Invention the following is a
complete description of same reference being had to the accompanying drawings:-
Fig. 1 is an elevation partly in section illustrating portion of a frame having my
improvements applied thereto.
Fig. 2. is an enlarged view of part of fig. 1.
Figs. 3-4-5 and 6 of sheet 3 are details or parts detached and drawn to an
enlarged scale.
The open legged flyer 1 carries the hauling pulleys 2 inside, the extremities 3 of
the legs 1 are left open so that the hobbin 4 traverses freely within and beyond the
legs and curls 5 of the flyer 1.
The flyer 1 and its carrying and driving socket 6 are made in two or more
parts 6-7 attached to each other, and to the driving pulley 8 by a key 9, the one
portion of this socket 6 being composed of the upper part of the flyer and the other of
a tube 7 fastened to the top of the flyer 1 forming together a supporting tube or socket
for the flyer of sufficient length to give steadiness to it and to afford space for the
requisite bearings 10-11 and space for the pulley 8 employed for driving the flyer.
The bobbins 4 are driven by the twisted yarns and are carried upon sockets 12
that revolve upon studs 13 which are fixed in the builder or traversing rail 14, the
bobbins 4 are caused to move or traverse concentrically with the flyer by means of a
rack 15 and pinion 16 to which alternative rotary motion is given by a mangle wheel,
quadrant or heart.
The hauling pulleys 2 with wheels 17-18 attached are carried upon studs 19-20
which are fastened to the arms of the crosspiece 21 connected to the lower part of the
socket 6 of the flyer 1 by the screw of pin 22.
The hauling pulleys are caused to rotate axially by the difference between the speed
of their orbital revolution and the speed of the central pinion 27 which is carried by
the internal tube 23 and works in the bushes 25-25, and driven by the V pulley 26
as its upper end, the central pinion 27 gearing into the wheels 17-18 on the hauling
pulleys.

page_text: The requisite drag to cause the bobbins 4 to take up the twisted yarns is applied to
the socket 12 that carries the bobbin 4 which is temporarily connected to the socket 12
by means of a pin or key 12 but I do not limit the invention to any special mode of
traversing the bobbin nor of regulating the drag thereon as any of the various known
arrangements may be used.
By the combination of specially constructed open flyer and hauling pullies a more
convenient working frame is obtained, the weight of the flyer is reduced, a higher
speed when desired can be obtained than is practicable with the flyer supported at
both ends and with the mechanism for traversing the yarn on the bobbin inside the
flyer as heretofore.
Having now particularly described and ascertained the nature of this my Inven-
tion, and in what manner the same is to be performed I declare that what I
claim is :-
The improvements in twisting frames comprising an open legged flyer having
olongated bearing when employed therewith are hauling pulleys and a traverse
motion for the bobbin all in combination and substantially as illustrated by annexed
drawings and herein fully set forth.
