The name actually refers to a glue the company had developed and sold in the 1930s to repair speaker cones, so there is an electrical connection.
The unit works very well. Insert the wire- looks like it could handle up to about a number 6- squeeze the handle and the left jaw clamps the wire, while the right jaw pulls the insulation coating off.
Patent here.
Long ago we did a post on the same device, labelled Trig-o-matic which appears to have been another company owned by the inventor.

So etwas ähnliches wird heute noch produziert
i would think it would be an expensive tool to make. There are so many simpler tools to cut and strip wire.
For production work though this type of tool helps insure uniformity and consistency...it's easy to cut halfway through a copper wire using some types of manual strippers.
When I googled it this came up: https://progress-is-fine.blogspot.com/2014/12/speedex-trig-o-matic-wire-stripper.html
Ha, Dave! I read the previous post and wondered if I should combine the two, I guess the inventor had a couple of businesses, and sold slightly different versions through both companies. The posts should be combined.

This is the one I've been using for over 30 years now and I love it. It's fully automatic and it's never cut any strands, at least that I ever saw.

Molded into the handle is "LICENCED BY ELCONTROL-ITALY" and this patent number:

It's so nice to use because you just stick the wire in and squeeze the trigger. No lining anything up and no adjustments but a tensioning screw that I've never had to touch since the MATCO guy adjusted it for me in his truck the day I bought it. I've picked up a few copies at garage sales but none of them work like this one.
