Wow! If you know anyone with a lighthouse you can sell the bulb to themOriginally posted by SidneyClockCo.:
Milwalukee Wis. is where they were made.
The bulb has a special screw in you can see the photos click on link and then double click photo to enlarge. Mine has a Hubbel screw in for the bulb and reads 660W250V The bulb has two slot to fit in. I'll photo the box and stuff better tonight. Pat. May 13 1902
Hope this helps.
Bulbs will do that, as will other devices. This sounds more like a baretter.Originally posted by Klossee:
The 660 watt is the standard rating for screw type light bulb base. It's a maximum safety rating of the socket. With out seeing the wiring schematic I would guess the bulb to be to be some sort of a surge current limiting device.
Less current!Originally posted by Richard Moore:
Just guessing, but the lamp probably acts as a ballast. As the magnetic field of the coil's large inductance builds up, more current will flow,
Only thing seems to be that there are only two actual contacts, interleaved with each other.the lamp will light brighter and finally most of the voltage applied will be dropped across the lamp instead of the coil. The effect would be to (relatively) slowly build up and then decrease the AC magnetic field inside the coil, where the object to be demagnetized, like a screwdriver, goes.
A further guess is that the slider on the right side is attached to the contact on a carbon pile resistive load that regulates the maximum strength of the field.
Probably looked impressive, Scottie, or maybe voltages in US varied? Dunno. England used to have DC mains in some areas up to the 1950s.Originally posted by Scottie-TX:
Wull, "Sure it does". An' I know it's easy to say now that all th' smoke's cleared - but I never could see th' purpose/interest in buffering surge voltage/current here. I mean - this' a chunka wire here! Certainly have enjoyed the digression tho.
Never mind, Tom, you could always switch them off as well...... :biggrin:Originally posted by Klossee:
OK mike I'll buy it. I never even thought of DC current. The slider is the only way it would work with DC. Over here AC DC is a rock group.
Looks good, CJ - slider as I thought.Originally posted by SidneyClockCo.:
Hello Ladies and Gents :biggrin:
Hey is the rest of photo's
Hope they came out ok.
