PROVISIONAL SPECIFICATION.
An Improvement in Machinery for Twisting and Laying of Ropes.
RICHARD HENRY ATTWATER General Mill Furnisher Manufacturer of Engine
Packings Asbestos etc. of 109 Church Street in the Town of Preston County of
Lancaster do hereby declare the nature of this invention to be as follows:-
Two circular discs of steel, iron, or other metal, with central flanges screwed to
an upright tube, up through the centre of which passes a fixed tube, on which it is
made to revolve. The discs are slotted at regular intervals with three, four or more
slots, for the bobbin carrier spindles to work in.
Between the two discs I fix an
inside tooth plate, & on the bobbin carrier spindles I affix wheels with
corresponding teeth to those in the plate, thus as the discs revolve carrying the
bobbins of yarn the wheels on the spindles engage with the tooth plate, causing a
reverse twist in the yarn, thus twisting & laying with one motion, the rope as it
is made being taken up by a suitable arrangement, the whole being bolted into a
square upright iron frame.

RICHARD HENRY ATTWATER Manufacturer of Engine and Pump Packings
in Asbestos Flax Cotton and other Material 109 Church Street Prestou and Atlas
Works Deepdale Road Preston 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 my invention consists of a square iron frame A. divided horizontally, into
four parts, on the top & the third, are plates with circular spaces B, on the second
is a fixed internal tooth plate C, on the fourth or bottom D, is a solid plate, having
bolted to its centre a short flanged tube, up through which passes a sliding tube F,
a little longer than the height of the iron frame, kept in position by set screws
through the flanged tube. Over this we have a loose tube G, reaching to the top of
the frame, on which we screw revolving circular discs H, that fill in the top & third
space; these discs are perforated with three, four, or more slots I, for bobbin
spindles, ou these spindles, midway between the two discs, we fix spur pinions K,
corresponding to the internal tooth plate, on the loose tube, between the bottom &
the third plate, there is a sprocket or other wheel L, for driving purposes. When
in motion this wheel carries with it the loose tube, on which the circular discs are
screwed, through the slots of which the bobbin & spur pinion spindles pass, thus as
the discs rotate, the spur pinious being in gear with the internal tooth place, causes
the spindles to revolve in an opposite direction to that of the discs, by this means
putting twist in the yarn on the bobbins, & laying them together in the form of a
rope, a suitable arrangement is made, by which the rope is coiled away as it is made.
The slots in the discs are so arranged that the spindles can be moved to allow of
changing the spur pinions, so that more or less twist can be put in, according to the
size of the robe.

page_text: Having now described & ascertained the nature of my said invention, & in what
manner the same is to be performed, I declare that what I claim is.
First. The internal tooth plate, &
Secondly. An arrangement of slots, & loose bushes for adjusting the bobbin
spindles for change wheels.
