Kirneya is caused by lifting a very heavy box of Kearneys.

Note that figures 9, 10, 11 “sleeve method” look like they may have been a predecessor to hydraulic-compressed splices.

Guys,
To a certain extent, we still use some of these tying techniques, although really only
for attaching lines to Insulators on poles or at service entries.
Crimp sleeves and split-bolts have done away
with most of the older jointing methods.

Guys, you have no idea of the "old school" methods of wiring. I have an American Electricians Handbook dated 1913! I also have a Hawkins Electrical guide that is dated 1927; and last but not least, I have a Practical Electrical wiring book that is dated 1947. You should see some of the methods that are explained in these books. All three books are in excelent condition. Signs with chasing lights had a drum and electric motor that turned the drum. The drum had "tits" like you would see on a music box and as the drum turned, the tits would make the limit switches turning on the lights in sequence. Wow, we have come a long way!

Signs with chasing lights had a drum and electric motor that turned the drum. So then that _IS_ how they work?!?! When I was a kid I'd stand under the metal awnings of some grocery stores with chasing lights around the rim and I'd hear a constant mechanical whir-whirr clank clank in rythm with the lights. I always thought it would be something similar to what you described Are these devices still made or have they been replaced by some sort of solid-state thing?

Directly for sign chasing, I doudbt it,
although the old (1987) school bus sitting
in the yard for storage, has a motor/contactor thing for the blinking lights as a schoolbus has.
To date still, the same sort of technology is used in the timers for appliances.
Of note, in high school, the shop teacher had
a little sign board with such a motor, and
the students got to dismantle the old scoreboard, which had appliance timer like motors/contacts for the timers and such
that are on a scoreboard .
