Greatest Wonder Of the Nineteenth
Century.
a NEW BANk LOCK WITHOUT ANY KEY OR
hEY-HOLE.

From ths Albany Evening Journal, Feb 1sas.l
Ne thought we bad obtained the ne pzu1 ultra
OF arathmetical and mechanical ingenuity, when
We got our Railroad Tiniet Press, which regis.
ters and numbers every ticket it prints as intelli
gibly as q clerk with pen aud inf, and with more
infallible accuracy.
But We hare been shown today an invention
n which the principle Of arithmetical combina-
ton is carried ont and applied to new use with
surprising results. This is bank lock which
absolutely defes the skill Of Hobbs.
1t works in this wise. Around the door knob
Of the Bank IS small brass index, on which are
numbers from to 100. You lock the door and
then set the index to UNI. number you piease
(say M} By turning to the right. You then
to the left, and then third number (say 1o) By
turning it to the right aguin. You then give It
tHirl, and 70 of and leave it.
In the middle Of the night, up comes burg
lar with his dark lantern and skeleton keys. He
examines the lock. No use for skeleton keys,
for there is no kcy-hole to put them in No use
for ganpowder, for there is no place to pour it.
it. That is all. Clearly, his only why to get in,
is 10 turn the knob to the right number.
He begins to try. He turns it to every num-
ber On the index, from to 100, trying the door
each time No 80. lie turns it back to every
number from 100 to l. Still no 20. When he
reaches the right number, there is no click OF
any other intimation that be hus reached it, and
he is rs likely to 60 past it as to stop. Granting
oven that he accidentally hits on the first num-
ber, he must lose it in trying to find the second
and third. He has to find the right three num-
bers. and find them in the same order that you
set them and keep each when found-in other
words, he must fnd the right one out Of over q
million combinations Of figures! If the night
was Is long as Ae.husalahfs life, the morning
would fad him at his unarailing work.
At nine clock you come along. turn the han,
die to the right numbers in succession, open she
bank with perfect ease, and attend to business
It is Of no use to knock down the Cashier Oh
his way home at night, in order 10 rob him o
the key: lie has no key. The key, such as il
is, is left in the door, All the Cashier has, il tht
memory Of certain figures in his head, whers
they can't be got ut.
Neither does its excellence depend On com
plex and secret mechanism. 1t is very simple
ANYBODY eau understand it, and the more thor.
oughly he understands it, the more completely
hccomprehends the impossibility unlocking it.
One of the chief troubles Of most bank locks
is, that they get out Of order. 4 cog is worn,
or spring faters and the lock won't turn, anil
then the Bunk Officers are kept out Us ell as the
burglars. But this one has no springs. II can.
not falter. 1t must turn when the right mum.
bers are known, and no amount of strength can
turn it when they are not.
The undersigned begs leave to say that the
article alluded to above, is " Covert's Permuta.
ton Bank Lock-" patented Oct. s. 1855, which,
is in use BY Banks in the State Of New York
and elsewhere, where they have given entirt
satisfaction.
As all Banks and Bankers will Of course de-
sire to procure as early as possible, lock nifh-
