20 Hz vibrator type ringing generator made in 1953 and stored safely away in a government
warehouse
until we bought them. What a find.
110 vdc input generates a 65v, 20 cycle,
50ma signal that will ring any telephone. Naturally this
is a vibrating inverter style. 2" x 2-7/8"H x 3-3/8"W. Four corner
mounting studs. Four insulated I/O terminals on bottom. Hermetically sealed.
Make your own telephone company. Great
kids project. 110vdc input easily made by rectifying AC, add
a filter cap and go. |

Believe it or not, this TA-1 handheld
ringer generator is a spare part for Patriot and Howitzer
Missle Systems. So states the military nomenclature. 1990's
vintage. May be hand charger for bomb detonator in which case
a capacitor is charged with a few cranks, enough voltage for
the blast cap.
Push on the spring loaded arm and enough
voltage is created to ring a telephone for a second or two.
In the top image you can see the magneto, sandwiched in ferrite
/ laminated core, centered between two coils. |
