INDY HAMFEST SWAG, PART THREE
A "what-is-it?" box. I was pretty sure I knew...
...Inside, a power transformer, top-hat diode, a lot of R and C and a relay (not visible in this photo) suggested what it might be. Two pots and a three-circuit jack on the front were a clue. A pair of insulated screw terminals on the back, marked "S" and "T" were the final giveaway: it's an all-passive-component automatic code keyer! The two pots are for speed and "weight," the timing ratio between dits (dots) and dahs (dashes).

Just a calibrated knob, you say? Have a look at the other side!
It's a nice old vernier dial, made by Crowe up in Chicago. (You can just read "CRO..." behind the drive at the lower center-left.) They've been gone for decades but their knobs and dials, etc. still show up. It's good stuff. Paid a couple of bucks. (The one mounting leg that looks broken was made that way. I don't know why.) It needs a little fixed scale to be a true "vernier" dial and I may have one the right size.

Pretty nice haul so far!
ReplyDeleteI have several of the National "Velvet Vernier" dials. I was given several LARGE boxes of "stuff" for helping to clean up an SK's shack. I keep the nicest ones, and sold some of the less pretty ones.
I assumed the open mounting ear on a dial like that was to allow a panel-mounted drive to line up with the shaft on a chassis-mounted control. But I can't for the life of me figure out how it works, not with two closed ears like that.
