PROVISIONAL SPECIFICATION.
Improvements in and in the Manufacture of Ropes for Use in Core
Making and Packing Purposes.
I, JOHN BUTLER, of 16, Cottrill Street, Pendleton, Salford, in the County of
Lancaster, Commercial Traveller, do hereby declare the nature of this invention
to be as follows:-
<<
It relates to the class of loose ropes made from hay, straw, or the loose shavings
known as
woodpulp," which have hitherto been used in foundries for wrapping
corebars in coremaking and similar purposes and relates more particularly to the
latter viz.woodpulp ropes which it is my object to render more dependable,
satisfactory, and cheaper, than heretofore. To accomplish this I use not only
the new woodpulp, but also waste woodpulp which has been used for other purposes
(such as packing cases), waste straw, lay, shavings, or any other suitable fibrous
material.
The material is first damped in a suitable kier and then undergoes a rougli
carding process so as to lay the fibres as straight as possible.
While still damp it is passed through a suitable twisting machine, furnished
with suitable bobbin flyers which pass suitable thread or strings of suitable material
round the outside of the rope to prevent it from untwisting when dry.
For packing purposes the rope may be used plain or passed through suitable
grease or liquid and afterwards pressed into the requisite shape by grooved rollers
or other suitable means.
PLETE SPECIFICATION (AMENDED).
Improvements in and in the Manufacture of Ropes for Use in Core
Making and Packing Purposes.
I, JOHN BUTLER, Commercial Traveller, of 16, Cottrill Street, Pendleton, Salford.
in the County of Lancaster, 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:-
It relates to the class of loose ropes made from hay, straw, or the loose shavings

page_text: known as wood wool, which have hitherto been used in foundries for wrapping
core bars in core making and similar purposes and relates more particularly to
the latter viz: wood wool ropes, which it is my object to render more dependable
satisfactory and cheaper than heretofore. To accomplish this I use not only the
new wood wool but also waste wood wool which has been used for other purposes,
such as packing goods in packing cases, waste straw, hay shavings or any other
fibrous material. The material is first damped in a suitable kier and then under-
goes a rough carding process so as to lay the fibres as straight as possible. While
still damp it is passed through a suitable twisting machine furnished with suitable
bobbin flyers which pass suitable threads or strings of suitable material round
the outside of the rope to prevent it from untwisting when dry, for packing
purposes the rope may be used plain or passed through suitable grease or liquid
and afterwards pressed into the requisite shape by grooved rollers or other suitable
rolls.
In carrying out the object of my invention, I proceed in the following way:
Figures 1 and 2 represent machine in elevation & plan.
A, Fig. 1, rough carding process, B, Fig. 1, hollow mandril in conjunction
with twisting arrangement B. Fig. 3, having sheave pulleys C, D, E, C & E
being fixed and .D, being capable of adjustment by a screw, the 3 pulleys are
carried between -2 cheeks or plates fixed to the hollow mandril B as shewn at F
Fig. 3, by the adjustment of pulley D. I am enabled to increase or lessen the
bight required for twisting the various sizes of fibrous materials, D', Fig. 1, is
a steam jacketted kier which can be removed when not required. When in use
the spun rope is passed through the sleeve E, the sleeve having a conduit on either
side G, G. leading the grease, oil or liquid composition from hopper. D', the
conduits G, G, are provided with 2 valves H, H, to regulate the flow of the com-
position or liquid on to the rope.
Having passed the spun rope through the sleeve E', I also pass it through a
second hollow mandril I, provided with suitable bobbin flyers which bind the rope
strands with suitable string or threads, after which I pass the rope through suitable
grooved rollers J, Fig. 1 and K, L, Figs. 4 and 5 being interchangeable any pair
can be used as shewn at J. The rope being now finished is coiled on to drum M,
Fig. 1, the drum being actuated by the longitudinal shaft O, Fig. 1, which shaft
is regulated for speed by the change wheels P, driven from shaft N, Fig. 1.. Q is
a pulley carrying 2 belts one open and one crossed these drive the bobbin flyers
in different directions, the rolls J, Fig. 1, are kept in position by lever & weight R,
the hopper S is for mixing the various waste materials with the longer fibres &
by suitable attachment of feed any percentage can be blended with the ropes.
Having now particularly described the nature of my invention and in what
manner the same is to be performed, I declare that what I claim is
1st. The improved method and apparatus for the utilizing of waste material
in the making of ropes, substantially as described and shown hereinbefore and in
the accompanying drawings for the purposes set forth.
2nd. The combined apparatus, substantially as described and shown herein-
before and in the accompanying drawings for the purposes set forth.
3rd. The improved method of and apparatus for twisting wood wool" and
other ropes substantially as described and shown hereinbefore and in the accom-
panying drawings for the purposes set forth.
4th. The improved method of binding wood wool" and other ropes with
threads or strings and the apparatus therefore, substantially as described and
shown hereinbefore and in the accompanying drawings for the purpose set forth.
Dated this 13th day of May 1895.
