Phonograph Needles
by Bas Ingrouille
As an addenda to the article which I
wrote on
'How Phonograph Needles are
Made',
and which appeared recently in our
newsletter, I submit the following further information.
Besides the steel needles described
in the previous article,
3/4 inches long
and
made in three diameters to play loud,
medium and soft volumes, there were many
more varieties of needles produced.
For
instance, the standard steel needle was
also
made gold and copper plated, which
was supposed to increase the
volume
and
tone;
but this writer could find no appreciable difference in the plated
compared
with the plain steel variety.
The steel
needle was
made in longer lengths in three
diameters so the needle could be set in a
longer or shorter position in the needle
holder, giving more volume.
This did work
as advertised.
Steel needles were also
made with a tiny washer welded to the needle shaft, the closer the point the softer
the volume, the further
away
from the point
the louder the volume
and in between gave
medium volume.
These also worked as advertised.
Steel needles also came with a stubby
point and with long points.
Still others
were made with a wavy shape, advertised as
being easier on the record because they had
a spring effect.
Still others came with an
L shape which also purported to impart less
pressure on the record and therefore less
wear and longer record life.
Still others
were made with a spade type of point and
others with the shaft flattened out at varying distances
from the point to increase
or decrease the volume.
These also had the
desired effect.
Some needles were made with
the standard size shaft at the top and
a
reduced shaft at the point end.
This difference in size varied in length to increase or decrease the volume.
Another
type was the cushioned point type in which the point, inserted in the bottom
end of the needle, was cushioned in rubber for a better tone.
Other steel
needles came with three coloured shafts, red for loud, green for medium and
yellow for soft tone and volume.
Some needles were made to give longer life and more plays per needle.
These were advertised as Pfanstiehl needles.
Some were semi permanent, giving up to 40 plays per needle;
still others were called permanent needles
with the 'Pfanstiehl'
point
hardened in a furnace to
5000 degrees and then
hand polished
under a microscope.
These were more expensive, initially selling for $1.00 each.
A unique device was invented to play
hundreds of records.
It consisted of a very
small bobbin wound with very fine hardened
steel wire.
The bobbin was clipped to the
back of the needle holder and the fine wire
inserted
down
through
a fine hole drilled
in the back of the needle holder where it
was held in place by the set screw.
The
wire could be adjusted at varying lengths
to give louder or softer volume.
When the
end of the wire wore, it was cut off and
pulled
down to give a new surface for the
record.
This device worked fine except that
the wire, not being pointed,
was hard on
the records
and scratched
them badly and
ultimately the device was not very successful.
During the
1914-18 war, needles were
declared unessential
and manufacturers had
to stop manufacturing them.
Machine owners
turned to sewing machine needles, breaking
them off so the point could be used to play
their records.
These
needles were not as
hard as the steel needles and so didn't last
as long.
Others turned
to using thorns,
and
some hard wooden needles were turned out
with one end sharpened.
Victor put out
3 sided
bamboo needles that
could be cut off on an
angle to give a new
point.
You will see
that Victor's Exhibition reproducer has
a
3 cornered hole in the
needle holder to hold
these needles.
Special needles
were
made to play Pathe
records, with a sapphire
inserted in the end.
Similar needles were made
to play diamond discs.
These had a cut
diamond
inserted in the end.
To
play Pathe or
diamond
discs with these needles
one had to have a reproducer that
could be turned so it faced vertical to the groove in the record.
Some companies
made reproducers
with
2 heads that could be turned
and allow playing of all types of
records.
Brunswick was such a
company.
If no needle is available
to play Pathes on a 78 player,
and
if the reproducer head turns on
your machine,
the point from a fine
ballpoint pen with
a suitable-sized
needle inserted in the back of the
shaft to hold in the needle holder
will suffice
and work well without any wear on the record. This is not
suitable for playing diamond discs however.
