STRAND FORMER FORl PARALLEL WIRE,
CABLES
David S. Fine, New York, N. Y.
Application February 16, 1937, Serial No. 126,054
6 Claims.
This invention relates to the spinning oi sus
pension cables and has particular reference to a
strand former for parallel wire cables.
In spinning parallel wire cables, the individual
5
strands which are to form the cable must be spun
and positioned in order to properly make the
cable. It is highly desirable to spin the strands
in the positions that they will permanently oc
cupy as the strands then have predetermined
cross-sections and fit in the strand holding means
in the desired manner. In addition, it is possible
to dispense with the machinery required to move
the spun strands into position.
After the strands are spun and positioned, they
must be individually adjusted to the proper
amount of sag between supports. The strands,
spun in accordance with the teachings of the
prior art, are not easily moved relative to each
other as they are immediately adjacent and bear
20 ing upon each other.
One of the objects of this invention is to facili
tate the spinning of strands in their permanent
positions.
Another object is to maintain the desired cross
25 sections of the strands and the proper relative
positions of the strands.
Another object of this invention is to permit
one strand to readily be moved relative to the
remainder of the strands.
The above and further objects will be made ap
30
parent by reference to the following description
and to the accompanying drawings, in which:
Figure 1 is a perspective of one embodiment of
the device oi my invention;
35
Figure 2 is an end elevation of a unit formed
from several of the devices of Figure l;
Figure 3 is a plan of the unit of Figure 2;
Figure 4 is an end elevation of the units oi
Figure 2 positioned in a saddle, several strands
40 being received in one of the units; and
Figure 5 is an elevation of a saddle carrying a
cable and the devices of my invention.
Referring more particularly to the drawings,
the numeral 2 indicates generally a strand form
45 er which is made from a tubular member or a
plate 4 in which` a strand is to be spun. rThe wall
of ti e tubular member 4 is provided with a
straight, longitudinally directed slot or aperture
'à which extends the length thereof. The aper
50 ture i5 is adapted to permit a taut or stretched
(Cl. 14-22)
to correspond with the predetermined cross-sec
tion of the strand to be formed therein.
A saddle 8 is provided to receive and support
the cable which will be made from the strands
formed in a plurality of the strand formers 2. Cil
The strand formers 2 are extremely short in rela
tion to the length of the saddle 8 and a plurality
of them are preferably provided to receive and
position each strand in the saddle 8. Before
placing the strand formers in the saddle 8, they
are preferably formed into a plurality of units by
bars I0 or similar means being welded thereto.
The units may contain varying quantities of
strand formers 2. The apertures 6 in the tubular
members 4 must be positioned adjacent the upper
surfaces of the strand formers 2 when they are
formed into these units. The tubular members
4 comprising one unit should be in a plane and
have their bores parallel. However, before plac
ing one unit on top of another, the strands to 20
occupy the lower unit must have been spun there
in. The units are placed in the saddle 3, one at
a time, and are adapted to have a plurality of
strands simultaneously spun therein. ri‘he next
unit to be placed in the saddle 8 is constructed 25
and arranged to cover only strand formers that
have strands therein. The tubular members coin
prising a unit ordinarily should be welded to
gether at Il (Figure 2) in addition to being se*
cured together by the bars lli. The weld at il
makes the unit stronger and easier to handle
than a unit held together only by the bars I0.
The saddle 8 is adapted to receive the strand
formers 2 and position them therein to make a
parallel wire cable of the desired cross-section.
Means, such as blocks l2 and lock screws I4, are
carried by the saddle 8 for securing the strand
formers 2 in their desired positions. The strand
formers 2 are temporarily held in the saddle 3 by
the weight of one or two wires so that they keep
themselves positioned after a strand has once
been started to be spun therein.

embodiment of my invention, it will be under
