More specifically, the attachment in my co
pending application Serial No. 483,317 is an au
tomatically operable circuit make and break de
vice which is characterized by an inclined wire
rod or member adapted to underlie a bank of par_
allel correspondingly inclined harness wires, there
being adapter means for supporting this Wire ele
ment or rod on a predetermined part of the con
ventional loom frame, and further, a current con
ductor electrically connected with the wire and
adapted to be connected to a suitable part of the
conventional loom stop'mechanisrn. The adapter
The channel-shaped loom frame bars A of the
loom B have disposed thereabove the inclined
bank of harness wire C, the latter being con
nected to the regular jack structure D and pass
ing down over the pulleys E on the frame and be
ing attached to the harness F. These are all con
ventional parts.
The novel and improved attachment is denoted
by the numeral 6 and this comprises an` adapter
in the form of a bendable metal rod 1. This is
inclined and formed at its lower or left-hand end
with a loop 8 adjustably secured by a bolt and nut
fastener 9 to the adjacent web of the correspond
ingly adjacent frame bar A. This adapter is pro
' vided at opposite ends with insulators I0 and Il.

which is adapted to be removably mounted be

For reasons discovered from trial and error I
have found it possible and expedient to revise

form of a coiled circuit make and break Wire ele
