‘
In accordance with a preferred form of the
invention, the front disk 2 is secured in ?xed posi
tion to the shaft I, and the rear disk 3 is secured
to said shaft Iin such manner that it may readily
be adjusted longitudinally, but not rotatably,
thereof.
7
.
To this end, as illustrated in Fig. 5, the shaft I
may have its diameter at the end thereof ‘reduced
as shown at Ia so as to form a seat for the hub 20
of the disk 2, said hub 2a being maintained in 10
position by a nut member 5, and rotation of said
hub 2a with respect to- said shaft end- In. being
suitably prevented, as by a key 6, Fig. 2, which is '
received in adjacent slotted portions of the hub _
2a. and the reduced shaft end Ia.
>>
As shown in Figs. 1 and 5, the disk 3 is formed
with a hub So having an internal diameter such
that said hub may be freely moved longitudinally
of the shaft I in the manner hereinafter de-‘
scribed.' Coactable with opposite faces of the hub 20'
3a are the respective nut members 7 and‘ 8 which
are threaded to a threaded section lb of the
shaft I. Rotation of the disk 3 on the‘ shaft I is
suitably prevented, as by a key 9 which is re
ceived in adjacent slotted portions of the hub 3a
and said shaft I. As will readily be understood,
one of the nuts 7, 8 may be loosened, whereupon -
the disk 3 may be moved longitudinally along the
shaft i toward the loosened nut and then the
other nut may be tightened so as to clamp said
30
disk 3 in its position to which adjusted. The ar
rangement thus described constitutes a satis
factory means for adjusting the distance between
the two disks 2 and 3 for the purpose hereinafter
described.
35
As shown, the above noted guide plate 4 com
prises a hub 4a which carries one or more clamp
ing screws I0 utilizable for positively retaining
said guide plate 4 in an adjusted position on the
shaft I. Further, as shown, the guide plate 4 is 40
provided with a plurality of passages 4b distrib
uted just within the periphery thereof.
In accordance with the invention, the herein
before described disks 2 and 3 are adapted to carry
a plurality of spindles I l which are suitably
spaced with respectto the shaft I outwardly of
the periphery thereof. Each end of each spindle
II is supported by a spindle-supporting assembly
of novel construction as hereinafter to be de
scribed.
Thus, as shown particularly in Fig. 3, each
spindle-supporting assembly comprises a set of
coacting members I2 and I 3, the adjacent faces
of these members preferably being shaped as
shown so as to form a seat for the reduced spindle
end Ila to be associated therewith,

As shown on the drawings, the forming head of
my invention comprises a main shaft I which is
adapted to carry a front disk 2, a rear disk 3 and
which, individually, are disposed diametrically of

Further, by reference to Figs. 3 and 4, it will be
noted that the structure of either ‘disk 2 or 3, im
, mediately adjacent opposite faces of each’slot I4, _,
is provided with the-respective threaded passages
which receive the screws I6, respectively. Each
15 screw I8 is provided with a head I8a and, as
shown in Figs. 3 and 4, a pair of these heads I6a
coact with the adjacent upper surfaces of each
assembly member I3. Further, the structure of
either disk 2 or 3, at the bottom of each slot ll,
20 is provided with a threaded passage which, as
1 shown in Fig. 5, receives a screw I‘I having a head
, I‘Ia coactable with the adjacent face of the as
’.sembly member I2. The reasons leading to‘ the
provision of the adjusting arrangement compris
25 ing the‘ screws I6 and I‘! will be hereinafter re
"ferred to in detail.
‘In accordance with the invention, each of the
upper members I! of the various spindle-support
othersrnember or insert I3 is associated with the
rear disk 3 when positioned as shown in Fig. 8, a
left lay wire or strand is produced.
'
As hereinbefore stated, the disk 3v may be
moved either toward or from the disk 2 by ‘un
loosening the nut member ‘I. or 8 and then tight
ening the unloosened nut member against the 15
face of the disk hub 3a. As‘will readily be under
stood,'this may be done while the single [,wires
or strands W are operably associated with the
respective spindles “but, preferably, after said
single wires or strands W have been slackened 20
to some extent at theLIeft of the‘ disk 3. By so
doing, the“‘lay" or pitch of said wires or strands
W may be decreased or increased to thereby facili
tate the proper, positioning of the shaped or set
wires or strands in cable or rope formation C 25
at the sizing die I8.
‘
‘
'
An adjusting operation of the character de
scribed above is performed in those cases when.
ing assemblies serves as a guide'for a wire or ' the “lay” or pitch of the wires or strands is tof

To this end, each member I3, is formed
with an open slot I3a extending approximately
longitudinally of the shaft I. Further, as shown,
one side wall I3b of the slot I3a preferably is
curved as shown in Fig. a while the opposite side
be decreased or increased to a slight extent. If
the “lay” or pitch is_ to be decreased or increased
substantially, or if the helix diameter is to be-v
changed, it becomes necessary to substitute a
new set ~~of spindles II for those already in the
forming head. This is done by widely separating 35

in connection with my invention because decreas

through the forming head arrangement. These,
respective wires or strands W, because decreasing
wear of the spindles, and because decreasing the
power required for passing wires or strands
as will be understood, are features of importance
in connection with my invention. Further, in 75
amass-i
connection with an arrangement of this char
acter and as shown in Fig. 5, the reduced ends

face such, for example, as illustratedin Fig.’ 10 '
may be associated with each insert ii.
In Fig. 11, I have illustrated a modified form
of spindle-supporting or -_bearing assembly
adapted particularly for association with each
slot ll of the front disk 2 although, if desired,
spindle-supporting assemblies such as illustrated
Under some circumstances, the spindles H may ‘in Fig. 11 may be associated with the respective

may be employed. Thus, each end “D of a'
“are! the spindles H should be of such length
that the above noted adjustments of the disk 3
may readily be effected without rendering the
rotatable bearings for the various spindles un
satisfactory from an operating view point.
spindle H of Fig. 6 may be of square or other
suitable con?guration, such end being received
in a corresponding seat between the members l2,
15 l3 of the spindle-supporting assembly.
.
‘
As stated, the inserts or members ll of the
spindle-supporting or -bearing assemblies are de
tachable from the slots II, this being readily
accomplished after the various screws i5 have
20 been removed. This is highly advantageous be
cause these members l3, at their curved surfaces
I3b, take‘ the abrasive .wear of the wires or
'strands. Even though formed of suitable wear
resisting material, they are subject to considera
25 ble wear and must be replaced at times, this,
obviously being accomplished in a ready manner
as stated.
I Further, as disclosed, the bottom surface of
each slot i3a of an insert member [3 is disposed,
preferably, substantially ?ush with respect to the
peripheral surfaces of the respective spindles II.
This is advantageous because facilitating the
proper passage of the wires or strands along the
spindles ll.
‘
.
The .hereinbefore described screws I 8 may be
retracted whereupon the screws i1 may be oper
ated to change the position of the spindle bearing
assemblies in their respective slots as desired.
In so doing, the spindles ii are moved either
40 toward or from the shaft 1 without any sub
stantial change in the inclination of said spindles.
This is done so that the shaped wires or strands
automatically take the proper positions in the
sizing zone, the arrangement rendering this ad
justment possible being of distinct importance in
connection with the invention. The adjustment
of the spindles II as just described is accom
plished advantageously by reason of the provision
of the alined pairs of slots I l in the respective
disks 2 and 3, the slots ll of each pair of slots
being inclined and disposed in substantially par
allel relation so as to provide parallel, inclined
trackways for movement of the bearing assem
blies under the control of the respective screws l‘l.
As herein disclosed, the disks 2, 3 are of dish
formation and. therefore, the above noted pairs
of parallel, inclined slots ll may readily be pro
vided. In addition, as will be noted, each of the
disks '2, 3 is provided with a plurality of strength
ening ribs 23 disposed on the front disk surfaces
so as to resist fracture of the disks when sub
jected to the strain of the wires or strands 1mder
going the setting ‘operation. By virtue of the
provision of these ribs 23, the disks 2 and 3 may
be maintained at minimum thinness with the
result that the slots lia may be of minimum
length to thereby decrease friction, wear, etc.
In order further to decrease friction and wear,
each insert or member I 3 may-comprise a roller
2| of wear-resisting metal, Fig. 9, this roller be
ing disposed at a suitable angle, for example,
a right angle tothe path of travel of the wire or
strand which engages therewith. Alternatively,
further to reduce friction and for other desirable
75 purposes, a roller 22 having a curved, sloping
prises upper and lower members 24 and 25. The
upper member 24 may comprise either a right
’ or left slot 24a and, if desired, a roller 2|, 22 or
equivalent as hereinbefore described may bev
associated with said slot 24a. The lower mem
ber 25 is formed with a plurality of circular re
cesses 25a having cooperative therewith a cir
cular tooth or pin'26 upstanding from the head
"a of the adjusting screw l1. Positioning pins
21 are associated with the members 24, 25 and 20
said upper member 24 comprises opposite ?at
tened sections with which the respective screw
heads lid coact.
With the arrangement of Fig. 11, the screws
5 6 may be retracted whereupon the members 24,
25 may be elevated from. the tooth 26 and par
tially rotated in one direction or the other. Then,
said members 24, 25 may be re-seated, a dif
ferent recess 25a receiving the tooth 26, and the
screws Ii returned to clamping position. In this 30
manner, the spindle-supporting assembly may be
clamped in a desired position circumferentially of the associated spindle I I.
.
Assuming that the end slot I4 of the front disk
2 is equipped with a spindle-supporting assem- '-‘
bly as illustrated in Fig. 11, one or more of these‘
assemblies may be adjusted as just described to
increase or decrease the helix diameter and to
somewhat change the ‘path of ‘travel of one or
.more of the single wires or strands W whereby a
the various single wires or strands assume‘ a
better ?tting relation just prior to or at the
time that they enter the die l8. An arrange
ment of the character illustrated in Fig. 11 is
useful particularly in connection with non-cir- .
cular single wires or strands although such an
arrangement is also useful with circular single
wires or strands.
As shown in Fig. 2, it is desirable that the
front face ‘of the disk 2 exhibit a plurality of ,
concentrically arranged marks 28 which are seg
ments of circles concentric with respect to the
shaft I." These marks 28 may be calibrated in
a predetermined manner so as to assist the op
erator when adjusting the spindles H under the ,
control of the respective screws l'l.
When an adjustment is effected by movement
of the disk 3 either toward or from the disk 2
as hereinbefore ‘described, it will be understood
that the various screws I6 should be retracted to 60
some extent so as to permit the spindle-support,
ing assemblies to take new non-binding positions.
and, before operation of the machine is resumed,
the screws IT and i6 should be tightened to
positively retain the respective spindle-support
ing. assemblies in proper bearing positions. It
will be understood-that adjusting operations of
L
the character just described are important in
connection with the spindle-supporting assem
blies associated with the disk 3 and, likewise, such 70
adjustments may be important in connection
with the spindle-supporting assemblies for the
disk 2.
The arrangements of my invention are particu
larly useful in connection with the shaping'or 75

are six spindles and a corresponding number of
bearing assemblies for each spindle end. As well,
if desiredpa greater or less number of spindles
may be utilized as desired. -
