PROVISIONAL SPECIFICATION..
An Improved Machine for Laying and Twisting Twines, Lines
and Cords, and the like.
I HERBERT NELSON; HARRIS of St. Michaels Foundry Bridport in. the.
County of Dorset Engineer do hereby declare the nature of this invention to be as
follows
For the purposes of my invention I have end frames with a spindle mounted in
cross-bars on either side, one may be called the laying spindle and the other the
finishing spindle these are driven by means of belts and two independent shafts
which, are
are in their turn driven from the main shaft by means of gear, the speed of
either of these independent shafts may be altered at will: first refer to the
so-called-laying spindle which runs in suitable bearings.
On the top bar I mount a pulley on a sleeve through- which the main spindle
passes. 1, either make this pulley conical or to revolve, above this I fix to the
spindle a cross-tree with two, three or more arms, the top of the spindle running in
a suitable bearing.
On the aforesaid cross-tree I have two, three or more frames open to slide on the
said arms, in each of tliese frames I have a hollow spindle to one end of which I affix
a fly to carry the laying bobbin vertically I also affix to it a friction roller, at the
other end I affix a suitable frame in which are mounted two or more cylindrical
grooved rollers open to revolve. The friction rollers carried in the aforesaid
frames are kept in contact with the pulley by means of bow-springs. On the
spindle revolving it carries with it cross-tree and frames. The friction rollers
running against the pulley causes them to revolve in the opposite direction to the
main spindle. The yarn etc. is taken from the bobbin up through the hollow
spindle passed round the cylindrical grooved rollers till a suitable grip is
obtained, is there twisted and layed, and passed through a suitable head to
the drawing rollers (there are two pairs of these rollers, both pair cylindrical
and grooved) and from thence to a fly which puts in the necessary additional twist
in the ordinary y
way.
The drawing rollers are driven by a suitable train of gearing and their speed can
be altered at will.

To obtain the necessary drag or tension upon the yarns I have an adjustable
means of applying friction to the aforesaid cylindrical grooved rollers around which
the yarn is passing.
Should one of the yarns or threads break, the two opposite spindles and the
drawing rollers engaged in that particular work stop the mechanism is as
follows-The yarn is passed through an eye in a pin, keeping that pin suspended,
should the yarn break, the pin drops and comes in contact with a lever causing
those spindles and drawing rollers to stop as aforesaid.

An Improved Machine for Laying and Twisting Twines, Lines
and Cords, and the like.
HERBERT NELSON HARRIS St. Michaels Foundry, Bridport Dorset Mechanical
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:--
My invention is an improved machine for laying & twisting twines, lines cords
and the like providing suitable mechanism for driving the laying spindles, also for
stopping the mechanism belonging to each set of spindles in the event of one
or more yarns breaking, also providing a suitable tension or drag, to keep the yarn
tight whilst being operated upon.
In the accompanying drawings Fig. 1 is an end elevation. Fig. 2 a front
elevation, showing one main laying spindle. Figs. 3 & 4 are enlarged elevations of
the laying bobbin carriage. Fig. 7 a plan of tension or drag. Fig. 6 a plan of a
carriage & arm.
I have two end frames 1 braced together by the bars 2, 3 & 4 off the end of
one stands the stool 5. I have 3 bearings in the lower end of the main frames,
carrying shafts 6, 61, 62, the outer end of shaft. 6. being carried by stool 5,
on shaft 6 mount pulleys 15 for main driving, and pinion 14 for driving
shafts 6' & 63, also bevel pinion 17 for driving shaft 16. Shafts 61, 62 are driven
by the gearing 9, 10, 11, 12,--9, 10 being change wheels, on 6', 6' are mounted
pulleys 7 & 8 for driving the spindles A, B, by means of belts on the fast & loose
sheaves A-B¹.
The drawing rollers are driven by bevel wheels 17, driving vertical shaft 16,
driving bevel wheels 18, driving cross shaft 19 to the outer end of which is
fixed a change wheel 20 driving the roller shafts through the gearing 24, 24",
25, 25, 26, 26, 27, 27, Fig. 1. & II.
I now come to spindle A on this I fix the driving sheaves A. I fix a bevel
pinion running in bevel wheel D, which runs on a stud carried by bracket D¹
into pinion E. E is a long sleeve open to revolve on spindle A. Pinion E &
pulley are one with the sleeve. Above this fix cross-tree F having 2, 3 or
more arms F1, F2 on these arms slide the carriages G, which carry the friction
sleeve G¹, tension carriage G2, hollow spindle G³ & flyer & bobbin G, G.
On the top of spindle A is an eye H conical at the lower end & straight at the
top end I put vertical grooves in the conical part for the yarn &c. to pass along,
each groove terminating at a hole through the straight part, the top is steadied by
running in a bearing formed & held by the bracket I which is made fast to bar 3.
I have also a smaller bracket J on the bracket I carrying the sheave J' to keep
the twine &c. central.
It will be seen that on spindle A. revolving pinion C, cross tree F, are carried
with it but sleeve E' runs in the opposite direction caused by the action of wheel D,
therefore the laying bobbin spindles G³ rotate in the opposite direction to the
spindle A & at an accelerated speed to which they would do were the pulley E
at rest.
Fig. III. IV. V. VI. I will now describe the carriage G, which is a frame made
to slide on the arm F, carrying in its top end the hollow spindle G³ & in its lower
end the bearing G on the top of spindle G³ I fix the frame G carrying
the tension rollers K, mid-way is fixed the sheave G & at the lower end the
flyer the step of this flyer runs in the bearing G. At the lower end of flyer I
have a pin to suit the bore of the bobbin in use, at the top end a sliding plate with
a like pin, the plate is lifted to remove or replace bobbins & is pressed on the
bobbin to hold it tight enough, to prevent its revolving until pulled by the yarn;
by the springs G³, G'

page_text: The frame G2 carries 2 or more cylindrical grooved rollers K open to revolve on
spindles K, at the end I have a bush K³ open to slide but not revolve on
spindles K this is forced against K by the springs K & causes friction when the
rollers are caused to revolve, to obtain the necessary amount of friction to suit
heavy or light yarns I set up the springs by means of nuts K' which screw on
the bush K3 or on the spindles at the end of the springs.
This tension or drag forms the subject matter of a separate application
for Letters Patent.
Fig. III. On the top of the carriage G is plainly shown a wire L bent to shape
with an eye at G¹³ & swinging on the pins G, this is kept upright by the
yarn passing through the eye G¹³, the wire is also bent so as to project over the pin
Fig. IV. which is slung by the wire at L. As will be seen this pin is held
in suspension by the yarn at G if the yarn should break the pin drops & strikes
the lever L, knocking it out of the slot or notch in L'.
The course of the yarn from the laying bobbins to the finishing bobbins is
as follows.
Fig. III. From the bobbin G round the wire Go up through the hollow
spindle G³ through the eye G2 passes round the tension rollers a sufficient number
of times to obtain the desired grip is there twisted passes through the eye (3 to
the eye H through which it passes & is there layed, is drawn over the frame by
the rollers 22,28 & has the extra twist put in by the flyer B2 in the ordinary
manner.
The flyer B² its bobbin, transverse plate & transverse motion being like that in
every day use needs no details.
I have explained the cause of the pin L3 striking the lever L which swings on
the pin L carried by the bracket L' through which the rod L' also passes in this
rod a cross slot or notch is cut for the lever L to enter on the pin L³ striking
the lever it leaves the slot in rod L' which frees the stopping gear which I
will now describe.
Fig. I. & II. I have to each set of main spindles a shaft M³ Fig. I. across the
machine free to turn in eyes M Fig. 11. to this shaft I fix arms M' fitted in
clutches 22 at opposite sides of the machine M³ is fastened to rod L' & the other
arms N' & N to rods M & M³ respectively to the bottom of which are fixed belt
forks M6 M7.
It will be seen that the rod L' being free is caused to rise by the spring M³ placed
under the arm M³ the shaft caused to move round, the arm M throws the clutch 22"
out of gear, & the rods M M lift the belts onto the loose sheave at A'; B₁ thus
stopping one set of spindles & drawing rollers.
The drawing rollers are as shown 22, 23, 28, 29 Fig. I. around which the twine
passes to obtain the necessary grip.
The handle N is used to put the spindles in motion when required.
The spindles A & B are driven in either direction at pleasure.
The rollers 23 & 29 are not driven, but caused to revolve by & with the twine.
The carriages G are kept to their work by the springs.
Having now particularly described and ascertained the nature of my inven-
tion, & in what manner the same is to be performed, I declare that what I
claim is
1st. The cross-tree F, carriage G, hollow spindles G³, vertical laying bobbin G,
flyer G, tension rollers & frame G, as described & illustrated on the accompanying
