APPARATUS FOR BONDING THE ENDS OF
WIRE ROPES
Frank E. Stahl, Tonawanda, N. Y., assignor to
Columbus McKinnon Chain Corporation, Ton
awanda, N. Y., a corporation of New York
Application March 17, 1936, Serial No. 69,342 _
6 Claims. (01. 113-99)
My invention relates in general to apparatus
In Fig. 1, I show the end iii of a length IQ of
for holding wire rope which is being cut and sub
wire rope it which has been severed and bonded
sequently welded. Reference is to be had to ap— in my apparatus. As here shown, the ends of
plication Serial No. 69,341 upon Methods of bond
the wires and strands have been welded together
5 ing the ends of wire ropes which contains sub
ject matter common to this application.
‘It is well known to those skilled in the art that
in all wire rope, except that which is initially
preformed, the wires and strands will ?y apart
10 and become unraveled when the rope is cut
through, thus making it necessary when cutting
‘or splicing such rope to provide a number of
seizings.
Furthermore, when the rope is to have an an
15 chor attached to the extreme outer end thereof,
such seizings obviously cannot be used because
they must be located as near the outer end as
possible.
‘
‘
The principal object of my invention has been
20 to provide an apparatus for holding wire rope as
it is being out without having to provide and to
apply seizings to the ends of the rope.
Another object has been to provide an appa
ratus in which the individual wires and strands
25 at the end of the rope may be securely held
against unraveling without the use of seizings
while being bonded together.
Another object has been to provide an appa
ratus which shall be inexpensive to manufacture
30 and convenient to use.
The above objects and advantages have been
accomplished by the device shown in the accom
panying drawings. In the drawings, where I show
the wire rope broken off, it is to be understood
35 that the broken~off part is either connected to
the reel of wire rope (not shown) or to the sev
ered length, the other end of which has been pre~
viously bonded. In the drawings:

and a cap H has been welded over the top, thus
providing not only a bond for the strands and
wires, but closing the end of the rope, sealing in
the hemp cord, if the rope is so provided, and thus
providing an end which is stiff and rigid and one
which cannotkunravel.

My invention which is shown in Figs. 2 to 8,
inclusive, comprises a bench vise l2 having a front
movable jaw l3 and a rear stationary jaw M.
The movable jaw is operated by means of the
vise screw l5.
15
Arranged between the jaws l3 and M of the
vise are two clamping blocks iii and two clamping
blocks i'l arranged in pairs. The blocks iii are
arranged at that side of the vise which receives
the wire rope it as it comes from the reel (not
shown), and the blocks l“! are arranged at the
opposite side of the vise jaw for the purpose of
clamping that portion of the rope which is to-be
come the severed length 59. The blocks are so
proportioned and positioned that a space 29 is
provided between them for the accommodation
of any suitable mechanical cutting tool, or an
oxy-acetylene ?ame. One of the blocks i6 is
pivotally secured to the coacting jaw 23 by means
of a pivot pin 26, and the other block is likewise
pivotally secured to its coacting jaw it by means
of a similar pivot pin 26, see Fig. 6. Each of these
pivot pins is arranged with its axis at right angles
to the axis of the wire rope or to the axes of the
grooves 33 of the blocks, such pivot pins being
disposed preferably near the bottom of the block
and in the central portion thereof, and each is
preferably driven into a suitable aperture formed
in the block. The pins have their ends protrud
ing beyond the outer surfaces of the blocks and
are pivotally ‘disposed in apertures 2‘! formed in
the jaws of the vise. Each of the blocks l5 and
H is provided in its inner working face with a
semi-cylindrical groove 33 for the accommoda~
tion and‘clamping of the wire rcpe. The blocks
it are held in de?nite spaced relation with each
other by means of a bolt 26, and the blocks i?
are likewise held together by means of a similar
bolt 28 (see Fig. 5). Each of these bolts passes
through an aperture 29 in one of the blocks of
each pair and into a screwthreaded aperture 30
in the opposite block of the same pair. The head
3! of each of the bolts is disposed in a countersunk
aperture 32, the depth of the aperture being so
proportioned in relation to the head M of the bolt 55

that the blocks of each pair can open slightly so as
to permit the free passage of the Wire rope there
rope, because of the fact that such a ?ame must
between, but the parts are, however, so propor
tioned that the blocks of each pair will be limited
rope together at the rope ends and in the forma
tion of the caps II. After the wire rope has been
in their relative movement so that they cannot be
clamped by the two interspaced pairs of blocks,
separated from each other far enough to allow
the rope to become disengaged from the grooves
33 and thereby fall out from between the blocks.
as shown in Figs. 2 and 3, it is ready to be sev

clearance between them when the rope is clamped.
One of the blocks I1 is pivotally attached to
the vise jaw I3 by means of a screw 36, and the
other block I 1 is likewise pivotally attached to the
to the length of the screw 36 that there is some
After the Wire rope has been severed, as shown
in Fig. 7, the screw I5 of the vise I2 is loosened
slightly and the workman then grasps the por
tions of the rope extending outwardly from each
of the pairs of blocks I6 and H, and by bearing 15
down upon these portions causes the pairs of
blocks I6 and I ‘I to be rotated, the blocks I6 ro
tating about the pivot pins 26, and the blocks I‘!
rotating about the pivot screws 35. The blocks
are rotated through substantially 90°, which will 20
bring the ends of the two portions of the rope
above the upper edge of the jaws I3 and M of
the vise, as shown in Fig. 8. These severed ends
space between the bottom of the aperture and
will also project slightly beyond the pairs of
the bottom surface of the head of the screw,
blocks I6 and I'E, in the position shown in Fig. 8. 25
The workman now, by the use of the oxy-acety
lene ?ame, will burn off the gobs 42 from each
of the rope ends, thus making a substantially
even end. The workman will then also, by the
use of this ?ame, weld together the wires and 30
strands of the upturned ends and will also de
posit metal upon such ends, thereby forming the
caps II, shown in Figs. 1 and 8. In such welding
and in the formation of the cap, the wires and
jaw I4 thereof by means of a similar screw 36
(see Fig. 4). Each of the screws 36 is slidably
and rotatably mounted in an aperture 3'! formed
in each of the blocks IT and screw threaded to
its respective vise jaw.
The head 38 of each of
these screws is disposed in a countersunk aper
ture 39 formed in each of the blocks, the depth
of which aperture is so proportioned in relation
1. VI
which will permit some motion between each of
the blocks and its coacting vise jaws. By this
arrangement, each of the blocks I ‘I will be held
to its respective vise jaw in such manner that
when the movable vise jaw I3 is opened, the
blocks I‘! attached thereto will be moved there
with and separated from the other block IT at—
tached to the jaw I4. By this construction the
end of the rope which is being loosely held by the
block I6 may easily enter between the blocks I‘!
when another length of rope is to be severed and
bonded.
A stop pin 4| is provided for the blocks I6
and a similar pin 4| is provided for the blocks
IT. Each of these pins passes through both of
the blocks of each pair and extends a slight dis
tance beyond the outer faces of each block, so
as to contact with the upper surfaces of the vise
jaws I3 and I 4 and thereby act as stops to limit
the inward rotation of the blocks upon their
pivots, as shown in Figs. 2, 4, and 5.
When my apparatus is to be put into use, the
vise jaws are opened and the wire rope I8 is
threaded in between the blocks I6 and also in
between the blocks II, the rope coming from the
reel (not shown) being moved during such
threading operation in the direction of the ar
strands of the rope are welded together so as to 35
make the extreme end of the rope one single
integral piece, so that when the welded rope is
released from the clamping action of the pairs of
blocks I6 and H, the wires and strands cannot
40
become unraveled or ?y apart.
It is to be understood that after the rope has
been severed and before the ends thereof are
welded, the jaws of the vise are loosened just
sufficiently to permit the operator to rotate the
pairs of blocks I6 and I1 about their pivots, but
not enough to release the clamping action of the
4.5.
pairs of blocks upon the wire rope to such a de
gree as to permit the rope to become unraveled.
After the severed ends of rope have been weld
ed, as above described, the vise jaws are released 50.
and the pairs of clamping blocks are again ro~
tated on their pivots in reverse direction so as
rows shown in Figs. 2 and 3. The rope is ex
tended on through the blocks until the place
where it is desired to sever the rope is located
to bring them to their initial positions where the
stop pins 4| will contact with the tops of the vise
jaws. The length of rope I9 (capped at each 55
in the space 20 between the pairs of blocks I6
and IT, a trough and stop (not shown) being
provided, if desired, for the reception and sup
end) is now removed from between the blocks
I‘I. If the jaws have not been sufficiently re
leased so as to permit the free passage of the rope
port of the wire rope as well as for the gauging
00 of the length thereof. After the rope has been
between the blocks, the jaw I3 is further opened.
As this jaw is opened, it will separate the blocks
I'I because of their attachment to the jaws by
the pivot screws 36, and thus permit the free
drawn through the blocks I6 and H the prede
termined length, the screw I5 of the vise I2 is
used to move the jaw I3 toward the jaw I4 and
to thus ?rmly clamp‘ the wire rope between the
coacting blocks I6 and the coacting blocks I'I.
As hereinbefore stated, the pairs of blocks I6
and I‘! are separated so as to provide a space
20 therebetween in which the rope may be sev
ered by any suitabale means. A saw, either
hand or power operated, may be used to sever
the rope, and in some cases it may be necessary,
when a saw is used, to provide a slot (not shown)
in the vise jaws for the reception thereof. I
have found, however, that an oxy-acetylene
?ame is a very convenient means of severing the
passage of the rope therebetween.
The wire
rope I8 coming from the reel (not shown), with
its end capped, is now moved along between the
blocks I6 and between the semi-cylindrical re
cesses of the blocks IT. The rope is continued
on until the end engages with the stop (not
shown) for the gauging of the next length I9,
whereupon the vise jaw I3 is again clamped in 70
position, thus securely holding the rope between
the jaws I6 and I1 ready to be severed at the
place in the space 20 between the pairs of blocks,
as hereinbefore described.
For convenience, in the appended claims, I 75
