HERBERT NELSON HARRIS Mechanical Engineer St. Michaels Foundry
Bridport Dorset. I do hereby declare the nature of this invention to be as follows,
and refer particularly to my drawings and Complete Specification No. 12034 dated
August 1st 1890:-
I keep the general arrangements the same as before, but drive the sleeve & pulley
(that drives the laying bobbins) at any speed and in either direction at will or it is
held at rest.
I also place the tension rollers on the top of the bobbin spindles, the laying
bobbins & flyers next, and the driving sheaves at the bottom.
The said laying bobbin spindles and therefore the bobbin & flyer I drive off the
said pulley either with round or flat band or belt.

COMPLETE SPECIFICATION.
Improvements in Machines for Laying and Twisting Twines, Lines,
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 for improvements in machines for laying & twisting twines, lines,
cords & the like providing suitable mechanism for driving the laying bobbins; also
mechanism for stopping 1 set of spindles & their accompanyments in the event of one
or more yarns &c. breaking also providing a suitable tension or drag to keep the
yarn tight whilst being operated upon.
In the accompanying drawings
Fig. I is an end elevation.
Fig. II a front elevation showing the driving gear & one main laying spindle.
Fig. I an enlarged view of one of the laying flyers & its accompanying
mechanism.
Fig. I & II I have main frames A braced together by the bars C, C³, C², C³, C4, C³
off the end of one is fixed the bracket B. I have four bearings in the main frame
carrying shafts 1, 7, 10, B', the outer end of shaft I being carried by bracket B. On
the outer end of shaft 1 I mount pulleys 2 for main driving also wheel 3 for driving
shaft 10 through the wheel 9 & change pinion 11, this is fixed to the end of shaft 10,
also wheel 4 for driving shaft 7 through the wheel 6 & change pinion 8, this is
fixed to the end of shaft 7. Also pinion 5 for driving shaft 15 through the
gearing 12, 13, 13 (see Fig. II) 14 to change pinion 15 this is fixed to the short
shaft 15" on the other end of which is fixed wheel 17 gearing with wheels 16, 18,
which are fixed to shafts 16, 18" along which are arranged the drawing rollers.
Also wheel 19 for driving shaft B through gearing 20; gearing & reversing
plate 21, gearing 22, 23, 23" 24 to change pinion 25 which is fixed to the end of
shaft B'.
Along shafts 7 & 10 are arranged bevel wheels 26, 27 two to each of the
pinions 28, 29 for reversing the motion, pinions 28, 29 are fixed to the lower ends
n

page_text: of vertical shafts D, D' which are carried in bearings in the bars C6, C7, C8, C³, on
these shafts are fixed pulleys D2, D3 driving by belts D1, D³ onto the fast & loose
sheaves D, D' these driving at will spindles E, E'.
Having now described how motion is given to spindle E I will describe its
mountings on spindle E just above the bar C is mounted pulley F in one with 34,
free to revolve on spindle E, F is groved to receive either round or flat cords or
belts for driving onto sheaves F'; above these are fixed crosstrees G, G' with 2, 3,
or more arms according to the number of yarns &c. to be operated upon in the
outer end of each arm are bearings G2, G3, G₁ carrying the flyer H &c. as
shown.
It will be seen that on spindle E revolving the crosstrecs are carried with it, likewise
flyer H &c. Should the pulley F be held at rest the flyer H will revolve on its
own axis in the opposite direction to the spindle E, at an accelerated speed, but the
speed of the pulley F being changable in either direction by means of the shaft B¹
the speed & direction of which is at will therefore the speed of flyer H may be
increased or decreased at will putting just so much twist into the yarn &c. as may
be desired, or pulley F may be held at rest.
On the top of spindle E is an eye J conical at the lower end & straight at the top
I put grooves in the conical part for the yarn &c. to pass along each groove leading
to a hole through the straight part, the top is steadied by running in a bearing
formed in bracket J' which is made fast to bar J. I have also a smaller bracket J³
on the bracket J carrying the sheave J to keep the twine &c. central.
Fig. III. E is the main spindle, F pulley for driving F1, 34 is capable of being
driven at any speed and in either direction by means of shaft B', the bevel wheel 30.
driving pinion 31 which is fixed on the lower end of spindle 32 (see Fig. 1) to the
upper end of which is fixed pinion 33 (see Fig. 1) in its turn driving 34.
To place the hobbin H on the rod H I lift plate Ho & tilt the rod outwards
on the hinge at its bottom end, place the bobbin on the rod push it upright again
drop the plate H on to the rod which it enters & is pressed down by the springs H
these also apply enough pressure to the bobbin to prevent its revolving unless pulled
round by the yarn &c.
The flyer H is round in section of the legs at the bottom end is the spindle H
running in bearing G³; to carry the sheave F; & has a step bearing at G at the
upper end is the spindle H12 running in bearing G2. His hollow to allow the
yarn to pass up through to the tension rollers to the spindle H is fixed the tension
frame H2 carrying one, two or more groved rollers H8, H' open to revolve on
pins H, H between the side of the frame & the rollers is plate I', pressed up to
the rollers by spring I which is carried in the spring box I & adjusted by means
of the screw 1. It will thus be seen that when the yarn is passed round the rollers
a sufficient number of times to obtain the necessary grip, any required amount of
drag can be applied.
On each of the arms of the crosstree G¹ will be plainly seen the wire L bent to
shape & swinging on pin L with an eye L' also projecting over & holding suspended
the pin L³, as will be seen when the yarn is tight it holds back the eye L' therefore
the pin is suspended should the yarn break the pin drops, strikes the lever L
knocking it out of the slot in the rod K at L'.
The course of the yarn from the laying hobbins to the finishing bobbins is
plainly shown in Fig. I from the bobbin H' round the leg of flyer H up through
the hollow spindle H round the rollers H8, H a sufficient number of turns to
obtain the desired grip is twisted by the action of the rollers revolving passes
through eye I, through the eye I' (see Fig. III) to the eye J through which it
passes the 2,3 or more strands are here layed together drawn over the machine by
rollers J, J & has the extra twist put in by the flyer J in the ordinary manner.
The flyer J its bobbin, traverse plate & traverse motion, being like that in every
day use needs no details.
I have explained the action of the lever L leaving the slot L' in K; the rod K
passes through the bracket K¹ & is at the top end fastened to the lever M² this is

page_text: pinned to the lever M, fastened to the shaft M, this is carried & free to turn in
eyes M on this shaft also is fixed levers M³, M, M; M3 & M4 are formed for
clutch forks J', J8, M' operating the rod K. To the bottom ends of K & K² are
pinned the levers N, N¹. Thus when rod K becomes free to fall the shaft M is
moved round, the levers M3, M4 throw out the clutches J7, JB & the levers N, N¹
lift the belts onto the loose sheaves at D, D', the end of lever N also throwing out
the clutch N³, thus stopping one set of spindles & their accompanying parts at one
time.
The handle P is for putting the spindles in motion again after a break.
Having now particularly described and ascertained the nature of my inven-
tion & in what manner it is to be perforined, I declare that what I claim is
1-The cross trees G, G' carrying laying bobbins H', flyer H, sheave F' tension
frame & rollers H2; as described and illustrated in the accompanying drawings.
2-The mechanism consisting of 1, 2 or more rollers, with springs and adjust-
ments for applying a variable tension to the yarns acting as the twisting agent
in one; as described and illustrated on the accompanying drawings.
3-Shaft B', bevel wheel 30; bevel pinion 31, pinion 33, wheel 34, pulley F, as
described &c.
4 The application of a round or flat cord or belt for imparting motion to the
laying bobbins & flyers as described & illustrated on the accompanying drawings.
5-The mechanism for stopping one set of spindles & its accompanyments in the
event of one or more yarns breaking; as described and illustrated on the accom-
panying drawings.
6-The general arrangement of a machine for making twines, lines, cords & the
like; as described & illustrated on the accompanying drawings.
Dated this 21st day of March 1892.
In witness thereof I have hereunto set my hand.
