The many claims made by the first ~ in
ventor of the telephone can easily be dis
posed of by the fact that an ardent lover
over 200 years ago contrived to communi-
cate with his, no doubt, equally anxious
lady love by the use of common piece of
cord connected to a membrane covering
the end of two cups. The greatness of
this discovery was afterwards grasped by
keen intellects, and the result is perfect
network of telephone wires in every city in
the world. The Bell telephones fill long
distance requirements, but are too costly
for the demands of private houses, short
business lines, factory work, private lines
from house to Office and many other uses.
The demand of the times causes a need for
short line private telephones at small
rentals. In order to meet this want many
manufactures have sprung into existence
from time to time, but finally collapsed to
the verdict of worthlessness. To use the
words of the inventor of the Shaver Tele-
phone, Inventors striving for cheapness
have sacrificed acoustic properties, and
failed accordingly" This condition Of
things has precluded business men from
the general usage of short line telephones,
they simply waiting for system which
will not work well one day and fail the
next, mostly. as Mr.. Shaver says, for the
following reasons
ga mechanical or acoustic telephone
that will work we'll under all conditions Of
wind and weather, whatever the route de-
sired, has been heretofore unknown. Many
attempts have been made, but all have
been comparative failures, owing to the re-
verberation of the line-wire caused by
wind and rain the lack of means for
maintaining an even tension, and equaliz-
ing the contraction and expansion of the
hne-wire, caused by changes of temperature
and the inability to turn angles, thus limit
ing the use practically, to short and nearly
straight lines"
That these objections are overcome in
the "Shaver Invention has been amply
proven in New York and Boston alone,
these two cities being cited on account of
the difficulties attached to usages and con-
struction. In New York this telephone is
used by the Produce Exchange, Morgan
Iron Works (John Roach), Eighth Avenue
Railroad Company, American Express Co.,
N. Y, L. E. and Western r. r. Co., and
many others, and their testimony as I.
worth is of the highest. One of the pecu-
liarities of this telephone is it's sounding
qualities one can sit near the telephone
and, by facing the diaphragm, distinctly
converse without rising from chair at
desk, the invention being patterned after
natures self.
1t is we'll known fact the human ear
receives the vibrations of sound by means
of double cone of branching nerves, by
this means the vibrations striking upon a
comparatively large surface may all be con-
veyed to one point upon the brain. In
like manner, the inventors of the Shaver
system constructed a cone and truss
system of branching wires, by the use of
which q sound coming along the wire
would take several directions and spread
out SO as to set in motion the whole sur
face of the diaphragm. thus making the
sound much louder than had ever been ac-
complished before, and when used as
transmitter the sound of the voice striking
upon any part of the diaphragm finds a
direct road to the main line, and thus the
full power of the voice is utilized in vibrat-
ing the wire.
There is no doubt that for the USE of
business men, where short lines are re,
quired, this system is not only effective, but
cheap, aud the demand for the telephones
of this patent has been immense. Thou
sands of ines are to-day earning rental
of from So TO So 90 per months, with oruers
coming in as rapidly as the line men can
erect them, although in the country,
around factories and at private residences,
the lines can be purchased outright and
erected by the purchaser at little cost.
