in the principal hotels and public places on
trial. So far. those thatare up have dem
Onstrated their usefulness in a measure
far beyond anticipation. They are being
attached entirely to the Sunset iOng-dis-
lance telephones and work with success.
Fine reason for this is that the fong-dis-
lance telephones are the more sensitive
and better aid the operator in detecting
the sound of.the fallen coin through the
SLOT and thus its value. $50:
- The nSticsaitss t.iffarenes hatween the
new Invention and inc old wall telephone
is in the lower portion, or box, in which
the battery fer the traDsmitter is kept. 1t
Is much larger, being about the same size
as an ordinary gSail-box. Along the front
edge of the box are FIVE slots made for in
sorting the coins. The first one on the
right-band side is the dime slot. the second
the nickel, the third tie quarterdollar, the
fourth the half dollar and the fifth the
dollar. The haad phone, or ear-lrumpet,
hangs at its usual place at the side, II he
upper box and bells are similar 10 those of
any other telephone :. -.
Justto the, rear Of the Slot line, and'in
the center of the.frout half of the hox,.fs
fixed a bellows, the top end of which is
connected 10 a nickel-pta ted tube inning
along the arm TO the .transmitteT.e Directly
underneath the sl0ts:i a. double row ar
rangement of bells and gongs, inclosed fn
the front half of the box. Tie bells are so
arranged that by dropping a dime in the
slot for that purpose a bigh-nOte bell
sounds, followed Immediately by a eathe-;
dral gong. They are made to ring by tRe
dime falling upon the bells. This sound Is;
carried up through the. bellows 10 to she
nickel tube through the .:tTansmitter To the
ears of the operator on whose line the ma
chine is working. When nickel is placed

placed a. card giving his table of sounds.
On hearing a bell or bells she kpews that

slot, please" If he demonstrates and
asks to have 1t charged be will be kindly
told that the books are closed and that he
must pay tell to the silent collector before
he will be connected. The perfection in
the arrangement Of the machiiIe makes il
one of the very few Of its kind to which
notice of prosecution for ATTEMPTS to de-
fraud will not be attached. To cheat or
rob 1t is an imposslblity. as the number
of bells ringing and their sound will al
ways tell the exact amount deposited in
the slot. -. -
The receptacle for the coin after Il falls
from the bells is arranged as IN ii treasury
vault, The small drawer or pan catching
the coin is securely locked with a Yale
lock inside the main box. W hich is alsJ
locked In the same manner. AT the right
hand side Of the box is an oblong door
leading into the separate compartment in
which the battery is stored. The whole is
incl0sed in walnut case, nicely finished
and presenting an ornamental appearance,
except Tor its bulky size.
The introduction of the slot machine
will be blessing TO the telephone COM
panies and general public alike. In the
frs place it will do away with the abom-
Unable practice of non-subscribe rs stepping
in KIT door ~ s.borrow the use of your
telephone" Outlines subscriber, while
not feeling like refusing a customer or
friend. is not. only. annoyed and incon-
venienced himself. but. some one at an
other end of the line who is waiting to
speak TO him on business is likewise ham,
pered. This class of people has also been
a source of loss Of revenue to the telephone
companies. They use their instruments
ard batteries without any revenue being
derived therefor. The slot machine will
put stop TO all these practices.
