to linemen in connecting and disconnecting the
cable to the tie clamp.
What I claim is:
1. A tie clamp» for insulators, comprising, a cap
15
member having a compressible section adapted
to ñt over the head of an insulator, a clamping
band secured about said section„ a deck mounted
within said cap for abutting engagement with the
head of the insulator, a clamping element con
nected to the top of said cap, a like clamping ele#
ment pivoted to the ñrst mentioned element Yand
adapted to coact with the latter to clamp an elec
tric cable therebetween, toggle mechanism' mount
s
ed on said deck and connected to said second
mentioned clamping element, and an operating
lever pivotally connected to said cap and to said
toggle mechanism and operable for moving said
second mentioned clamping element into and out
of clamping position.
2. A tie clamp for insulators, comprising, a cap
member having a compressible section adapted to
ñt over the head of an insulator, a clamping band
secured about said section, a deck mounted within 10
said cap for abutting engagement with the head
of the insulator, a clamping element connected to
thetop of said cap, a like clamping element piv
oted to the ñrst mentioned element and adapted
to coact with the latter to clamp an electric cable 15
therebetween, toggle mechanism mounted on said
deck and connected to said second mentioned
clamping element, an operating lever pivotally
connected to said cap and to said toggle mecha
nism and operable for moving said second men
tioned clamping element _into and out of clamping
position, and a latch carried b_ysaidcap for lock
ing said lever in clamping position.
