2 Claims.
(01. 173-269)
This invention relates to improvements .in
washer lugs, such as are applicable to the ends
or terminal portions of wires or the like, to facili
tate and expedite anchoring of said ends or ter
minal portions to a fastener. Washer lugs ,are
most commonly used in the electrical ?eld, for
establishing electrical connection of a conductor
to, a binding post, contact screw, or the like.
An object of the invention is to provide a
washer lug having an improved form of folding
double head, including simple and effective means
to ensure accurate registry of the head elements
and of their respective binding post or screw aperl
shown by way of example comprising a pair of
bendable ears I8 and I9, formed upon ashank
20 integrally with the head element. Byplacing
the insulated portion of the conductor between
the ears l8—l9, and then bending the ears to
gether, the conductor may be securely clamped
to the washer lug, with the bared terminal end
of the conductor de?nitely locatedvrelative to the
head element [2. Thereafter, the other head ele
ment !3 may be folded over or bent to covering
relationship with respect to head element l2.
In order to ensure accurate registry of the head
