RIGGING CONNECTOR ELEMENT

My invention relates to an arrangement of rig
ging and a rigging connector element adapted
pendently to support a high lead block by a
length of cable upon a spar tree or similar sup
port in logging. The principal object of myl in
vention is to provide a rigging connector ele
ment designed to accomodate a length of cable
v
tion of cable I or so-called wire rope, having fer
rules 2 and 2’ fixed to the ends thereof. Said
actual'length of cable is selected such as to en
circle a-spar tree 3. Said length of cable droops
somewhat in looping about said spar tree and
thus is adapted to be fixed about various diamf f
etered trees. The rigging connection 4 with
which my invention Yis specifically concerned,
comprises an integral body 5, is more or less hol
having enlarged ferrules secured to the ends
thereof. Said rigging connector element is
adapted to receive said ferruled ends of the cable 16 low. ÀIt has two obliquely disposed elongated
expeditiously and to hold them securely. The
recesses 6 and 6' formed therein. The angular
rigging connections are arranged so that after
disposition of said recesses is shown best in Fig.
said ferruled ends of the cable are seated in ap
2. The angular alinement of said rigging con
propriate recesses therefor, and a high lead block
is secured in place by a bolt connected to the
nection and the disposition of the recesses is
arranged for a spar tree of a diameter, say
shackle thereof, said ferruled ends are prevented
thirty inches and the recesses are disposed with
from being removed until after said high lead `
block is ñrst detached.
A further and more specific object of my in
vention is to provide a rigging connector element
of this character which is adapted to accommo
date some angular movement of the ferruled
ends, not only to provide articulation; but also
to be ñtted to spar trees of different diameters.
To this end I provide recesses adapted to receive 25
the ends of the cable and extending outwardly
therefrom as is illustrated in Fig. 2. That por
the ferruled end of the cable through an open
mouth thereof and a' slot formed at one side
thereof. Said slot is adapted to pass a length of .
cable laterally, but to prevent a ferruled end pass
ing therethrough. The walls of said recess con
verge from the open mouth thereof towards the
socket end for engaging one end of the ferrule
seated therein and said latter end is rounded to
provide an action more or less similar to av ball
and-socket joint.
.
Other and further details of my invention are
hereinafter described with reference to the ac
tion of the exterior of the body lying between
said recesses is indicated as 1. Said portion 'l
is rounded, as is shown in ñgure, so as not .to
dig into and scar the barked surface of a spar
tree.
Extending substantially in alinement trans
versely of the open mouths Ea and 6a’ of recesses
6 and 6', respectively is a pair of alined fasten»
ing holes 8 and 8' adapted to receive va bolt .9
for passing through and securing shackle l0 for
high lead block Il to the rigging connector ele
ment. When said bolt is fastened thru said
fastening holes and is secured by nut 9a, neither
of the ferrules may be forced out of their recesses.
In other words, said bolt keys said ferrules in
their recesses to prevent their retraction.
The sidewalls of recesses 6 and 6’ converge
from their open ends 6a and Ea', respectively
thereof toward the rounded seats 6b and 6b'

by means of a length of cable, a rigging connector
is slightly greater than the diameterof the fer
element, and a shackle providing articulated
rules, while the diameter of the recess adjacent

seats v6a and 6a’ corresponds substantially to the
and said high lead block;

is shown in Fig. 2, the ferruled end of a cable
may be arranged as is shown in Fig. 2 and pulled
up so that the rounded end 2a of the ferrule may Ul
seat upon the seat 6b of the recess. When both
