Improvements in Apparatus for the Manufacture of Electric Cables.
We, WILLOUGHBY STATHAM SMITH, of 13, Courtfield Road, South Kensington,
in the County of Middlesex, Telegraphic Engineer, and WILLIAM PUDDICOMBE
GRANVILLE, of 36, Oakfield Road, Stroud Green, in the same County, Electrician,
do hereby declare the nature of this invention to be as follows:-
-
This invention relates to the manufacture of cables whether solid or air space
in which the core consists of two or more segments twisted together and contain-
ing conductors.
The segments are separately wound on the bobbins of an ordinary twisting
frame their ends being led up to a fixed head containing suitable rolls as herein-
after described. This head preferably consists of a number of rings to which the
supports of the rollers are removeably fixed so that other rollers can be readily
substituted for making different sized cables.
The first ring carries a pair of rollers for each segment one roller being grooved to
receive it and the other being cylindrical to bear against its flat face.
The second ring carries a pair of rollers each having a disc fixed to it, these
discs separate the flat surfaces of the segment from each other.
The third ring carries a pair of grooved rollers which press the flat faces of the
segments together.

segments of the core are led up to a head consisting of four rings ef g and h.
Figures 8 and 9 are elevations at right angles to each other of this head to a
larger scale and Figures 10, 11, 12 and 13 are plans of the four rings in the
positions shown at Figure 6.
The ring e forms the base and carries an inner ring el. The ring f carries two
pairs, of rollers one roller fl of each pair having a semicircular groove to receive
the half core and the other f being cylindrical. The ring carries a pair of
rollers g each having a disc, fixed to it. These discs separate the segments d' d
The ring carries a pair of grooved rollers h¹h which press the flat faces of
the segments together. j Figures 6 and 7 is a grooved pulley over which the
completed core is led to a winding reel in the usual way.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed, we declare that what we
claim is:
1
1. The pairs of rollers, one for each segment one roller of each pair being
grooved and the other being cylindrical to bear against the flat surface of the
segment substantially as described.
2. The rollers having discs fixed to them for separating the flat surfaces of the
segments from each other substantially as described.
3. The combination of the subject matter of Claims 1 and 2 substantially as
described.
4. Apparatus for the manufacture of electric cables substantially as described
and shown in the drawings.
