PROVISIONAL SPECIFICATION.
Improvements in Arrangements and Means for Driving the Flyers
and Haul Pulleys in Twisting Frames.
I ABRAM COMBE, of Falls Foundry, Belfast, Ireland, Machinist, do hereby
declare the nature of this invention to be as follows:-
The improved arrangement and combination of parts hereinafter described for
driving the flyers and haul pulleys in twisting frames, is specially applicable and
relates to that class of twisting frames in which the several yarns or threads to be
twisted together are passed over or through guides, arranged around the centre of
the tube, through which the yarns are drawn, by means of hauling pulleys in the
flyer as described in the Specification of Letters Patent No. 8018 of the year 1888,
granted to the present applicant.
The objects of this invention are to secure a positive predetermined difference in
speed between the flyer and the centre wheel, which gives axial rotary motion to
the haul pulleys in the flyer, and thereby to ensure positive and uniform twist being
imparted to the yarns or threads which are being twisted together.
These objects, positive relative speeds and uniformity of twist are attained by
improved arrangement for driving the flyers and haul pulleys as follows:-
The driving shaft of the machine extends the length thereof and is at right
angles to the sockets which carry the flyers, and on said shaft are placed worm or
screw wheels opposite to each flyer, which wheels gear with corresponding worm or
screw wheels on the flyer.
To drive the tubes carrying the centre wheels which drive the haul pulleys, a
shaft is used parallel to the driving shaft, having on it worm or screw wheels
opposite each tube, which gear with corresponding worm or screw wheels on the
tubes.
This second shaft is driven from the driving shaft first referred to by spur
gearing as follows :-
A wheel on the first driving shaft gears into a stud wheel cast or secured to
which is another wheel gearing into a wheel on the second shaft.
By these means the relative speeds of the flyer and of the haul pulleys are made
"positive," and as any of the four spur wheels which connect the driving shaft with
the second shaft which drives the centre tubes, can be used as "change wheels,"
the relative speeds of the shafts can be altered and adjusted according to require-
ments to a nicety and the amount of twist imparted to the thread can consequently
be varied with facility and certainty and as desired.

COMPLETE SPECIFICATION.
Improvements in Arrangements and Means for Driving the Flyers
and Haul Pulleys in Twisting Frames.
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:
The improved arrangement and combination of parts hereinafter described for
driving the flyers and haul pulleys in twisting frames is specially applicable and
relates to that class of twisting frames in which the several yarns or threads to be

page_text: twisted together are passed over or through guides arranged around the centre of
the tube, through which the yarns are drawn by means of hauling pulleys in the
flyer as described in the Specification of Letters Patent No. 8018 of the year 1888
granted to the present applicant.
The objects of this invention are to secure a positive predetermined difference in
speed between the flyer and the centre wheel which gives axial rotary motion to
the haul pulleys in the flyer, and thereby to ensure positive and uniform twist being
imparted to the yarns or threads which are being twisted together.
These objects, positive relative speeds, and uniformity of twist are attained by
improved arrangements for driving the flyers and haul pulleys as follows:-
The driving shaft of the machine extends the length thereof and is at right
angles to the sockets which carry the flyers, and on said shaft are placed worm or
screw wheels opposite to each flyer which wheels gear with corresponding worm or
screw wheels on the flyer.
To drive the tubes carrying the centre wheels which drive the haul pulleys, a
shaft is used parallel to the driving shaft, having on it worm or screw wheels
opposite cach tube which gear with corresponding worm or screw wheels on the
tubes.
This second shaft is driven from the driving shaft first referred to by spur gearing
as follows:——
A wheel on the first driving shaft gears into a stud wheel cast or secured to
which is another wheel gearing into a wheel on the second shaft.
By these means the relative speeds of the flyer and of the haul pulleys are made
"positive" and as any of the four spur wheels which connect the driving shaft with
the second shaft which drives the centre tubes, can be used as "change wheels "
the relative speeds of the shafts can be altered and adjusted according to require-
ments to a nicety, and the amount of twist imparted to the thread can consequently
be varied with facility and certainty and as desired.
Such being the nature and object of my said invention the following is a complete
description of same reference being had to the accompanying drawings forming a
part of this Specification in which,
Fig. 1 is a sectional elevation of so much of a twisting frame as is necessary to
illustrate the improved arrangements for driving the flyers and haul pulleys.
Figs. 2 and 3 arc side elevations of each end of the machine.
Fig. 4 is a detail of the ordinary "register plate" 16 drawn detached.
The driving shaft 1 of the machine extends the length thereof and is at right
angles to the sockets 2 which carry the flyers 3 and on said shaft 1 are placed worm
or screw wheels 4 opposite to each flyer 3 which wheels 4 gear with corresponding
worm or screw wheels 5 on the flyer 3.
To drive the tubes 6 carrying the centre wheels 7 which drive the haul pulleys 8
a shaft 9 is used parallel to the driving shaft 1 having on it worm or screw wheels 10
opposite each tube 6 which gear with corresponding worm or screw wheels 11 on
the tube 6.
This second shaft 9 is driven from the driving shaft 1 by spur gearing a wheel 12
on the first driving shaft 1 gears into a stud wheel 13 secured to which is another
wheel 14 gearing into a wheel 15 on the second shaft 9.
By these means the relative speeds of the flyers 3 and of the haul pulleys 8 are
made "positive" and as any of the four spur wheels 12. 13. 14. 15 which connect
the driving shaft 1 with the second shaft 9 which drives the centre tube 6 can be
used as change wheels the relative speeds of the shafts 1 and 9 can be altered and
adjusted according to requirements to a nicety and the amount of twist imparted to
the thread can consequently be varied with facility and certainty as desired.
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
The general construction, combination and arrangement of parts, comprising

page_text: flyers, hauling pulleys, and toothed and worm gear for driving the same, as herein
fully described and substantially as illustrated by drawings annexed.
