4 Claims.
(Cl. 173-263)
My invention relates to a connection cap for
electric conductor wires, more particularly for
joining electric conductor wires at their ends,
and the objects of my invention are:
First, to provide an insulation cap for cov
ering and connecting the ends of electric con~

portion between the points 2 and 3 to provide
sharp engaging portions for securing and con- 5

Having thus described my invention, what I
claim as new and desire to secure by Letters
Patent is:
1. In an electric conductor wire connection
cap, a spirally wound spring wire, a relatively
soft rubber cap like covering in which said wire
is embedded, provided with a central recess
shaped to expose the inner surface of said spirally
Wound wire for receiving the wires to be con
nected, and a ?at loop member integrally con
nected with the small end of said wire and the
whole embedded in a relatively ?at integral
portion of said covering.
2. In an electric conductor wire connection
15 cap, a spirally wound spring wire, a relatively
soft rubber cap like covering in which said
wire is embedded provided with a central re
cess shaped to expose the inner surface of said
spirally wound wire for receiving the wires to be
connected, a flat loop member integrally con»
nected with the small end of said wire, and an
enlarged coil integrally connected with the
larger end of said spiral and the whole embedded
in an integral portion of said covering.

3. In an electric conductor wire connection
cap, a relatively soft resilient insulation cap
member provided with a relatively flat handle
portion at one end and a hub portion at its op‘
posite end and with a central wire connection
receiving bore, a spring wire in spiral form, em
bedded in the interior of said cap with its inner
side exposed by said bore, and said spiral wire
extended at its smaller end in loop form em
bedded in the relatively flat handle portion of
said cap.
4:. In an electric conductor wire connection
cap, a relatively soft resilient insulation cap
member provided with a relatively ?at handle
portion at one end and a hub portion at its op
posite end and with a central wire connection 15
receiving bore, a spring wire in spiral form, em
bedded in the interior of said cap with its inner
side exposed by said bore, said spiral wire ex
tended at its smaller end in loop form embedded
in the relatively ?at handle portion of said cap, 20
and a greatly enlarged coil portion integrally
connected with the larger end of said spiral and
fully and completely embedded in the hub por
tion of said cap.
