Banjo Top-Crest Builders (Patent) Plate. An original cast bronze builders plate for
"The American Automatic Banjo Co. of N.J." |
The reddish colored bin at bottom left
holds the endless 5-tune music roll, which feeds upward through
the rollers and over the tracker bar (visible directly above the
red colored music roll storage bin). The electric motor (barely
visible to the right of the roll storage bin) is belted to the
pump assembly, which is located at the back of the machine. |
Two string picker assemblies are situated
on either side of the banjo, with the actual picking arms and
the tiny templates that describe their picking orbits supported
by the ornate nickel-plated metalwork. Each of the four
independent pickers is operated by a single, large pneumatic,
delivering a quick motion, with more than enough motive power to
do the job. |
Close-up of the left-side banjo picking mechanism. The two flat
springs forward of the pneumatics and ornate bracket offer
sliding resistance to the pivoted picker wires. This resistance
causes the pickers to follow "elliptical" orbits described by
tiny templates located about two inches inward from the banjo
end of the supporting bracket. |
