Improvements in Spinning Machines specially applicable to the
Spinning of Cordage, Yarns, and Twine.
We, ARTHUR TREDGOLD LAWSON, Engineer, and THOMPSON CRAISTER, Manager,
both of Hope Foundry, Leeds, in the County of York, do hereby declare the nature
of this invention to be as follows:-
-
This invention relates to machines termed automatic spinners or "Jennys" and
its object is to increase the strength and stability of the flyer so that it can be run
at a very high speed whilst the vibration of the machine is diminished.
For this purpose the flyer has two end plates or discs connected by telescopic
rods, one disc being movable relatively to the other and carrying the bobbin to and
fro with it.
The outer rods are hollow and are fixed at one end to an annular plate of metal
surrounding the bobbin. The other rods work telescopically within the outer rods
and are preferably also made hollow from end to end not only for lightness but also
to allow of the ready escape of air from the inside of the outer rods.
The outer rods carry tubular thread guides so as to prevent the yarn from being
deflected by centrifugal force and to protect it from the friction of the air which at
high speeds is apt to fray it. The ends of the tubular thread guides carry sheaves
to lead the yarn from the feed or hauling pulleys and to deliver it onto the bobbin.
In place of one set of rods being made to work telescopically within the others
they may pass through holes in the annular plate.

We, ARTHUR TREDGOLD LAWSON, Engineer, and THOMPSON CRAISTER, Manager,
both of Hope Foundry, Leeds, in the County of York, 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:-

they may pass through holes in the annular plate.
Figure 1 is a side elevation of a machine embodying our invention.
Figure 2 is a sectional elevation to a larger scale of the flyer head and bobbin
with their appurtenances.
Figure 3 is a transverse section on the lines 3-3, 3-3 Figure 2.
Figure 4 is a transverse section on the line 4-4 Figure 2, half of the bobbin
being omitted.
Figure 5 is an elevation of a vertical flyer with lifter.
A is the framing of the machine. B the main shaft at one end furnished with
fast and loose pulleys C which receive motion through the main belt D. E is a
horizontal shaft running lengthwise of the machine, and deriving motion from the
main shaft B through the bevel gearing a b.
The shaft E carries a pulley F for driving the flyer G and another pulley I for
driving the bobbin J. A worm on the shaft E gears with a worm wheel c¹, on a
vertical shaft c, driving by hevel gearing an endless screw K which imparts a to
and fro or traversing horizontal motion to the bobbin headstock K'K' (see Figure 2)
and the disc G¹ to which are attached the rods dd. The disc G₁ is fixed to a
sleeve working in bearings in the bobbin headstock K. The rods H H¹ and d d
we prefer to make of steel or other metal tubing so as to combine lightness with
strength.
The outer rods H H act as the driver of the inner rods d d and the disc G¹
The flyer rods H H₁ are fixed at one end to the annular plate L and at the other
end to the disc G, which disc G is made in one piece with a sleeve working in
bearings in the pedestals M M¹ and having fixed to it the pulley N for driving the
flyer. The rods H H are hollow for a sufficient distance to receive and allow the
rods dd to slide longitudinally therein or the rods dd can be made to slide in
holes through the annular plate L as shewn in dotted lines at Figure 4.
The rods d d are turned on the outside so as to slide freely backwards and forwards
horizontally in the rods H H¹ and are hollow throughout their entire length so as
to allow the compressed air to escape.
The rods HH' each carry a metal tube 001 (Figures 2 and 3) having at each end
a small metal pulley e and f to receive the yarn from the hauling pulleys gg and to
deliver or guide the yarn on to the bobbin J.
Figure 5 is an elevation of a flyer made to work vertically as used in a twisting
or spinning frame the disc G being at the top and fixed to a sleeve running in the
bearings M and M. The disc G is supported and runs in a lifter or builder K
which is worked vertically up and down in the usual manner in twisting and
spinning frames.
Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed we declare that what we
claim is:-
1. A flyer having two end plates movable relatively to each other but connected
by rods.
2. A flyer having two end plates movable relatively to each other but connected
by rods sliding telescopically one on the other.

page_text: 3. The combination with the subject matter of the preceding claims of an annular
plate connecting together the ends of one set of rods.
4. The combination with the arm of a flyer of a tube for conveying the yarn
to the bobbin.
5. Flyers substantially as described and shown in the drawings.
