Burglar Proof Safes.

Ibtt A~>~
AZ the Exchange Bank may be seen TWO OF
B,con's burglar-proof safes, with Coyert's pa
tent Formulation lock.
These safes are made Of plates OF the best
boiler iron, with intermediate plates IF the best
English spring steel, and having neither key
hole nor ~crcvicc, are hti' dill ard powder
proof. But their chief recommendation: is IN
the ingenious ana simple invention known rs
"Covert's patent Formulation hank lock,
which the Rochester Union and American
says:
"Wa as invented to Supplya iesideratum so ar-
parent to all who know anything Of safe locks,
and we think it fully answers the demand.
That bankers think 50, too, is clearly Indicated
by their readiness to introduce this lock as
soon us they witness its operation. Tins lock
has no kew, and there is 10 key hole Tor the
reception of explosive materials or picNS.
When applied to burglar.rroof safes, it is Oh
the inside of the door, beyond the reac;i oil
mischief from without, and is operated BY
common knob attached to I small cast steel
arbor. The turnin. of this knob controls the
lock in every movement. GRAVITY ard springs
are not known as agencies in the operation.
There arc but six movable pieces, ana 'll move
easily, no matter who turns the knob; but The
bolts cannot be withdrawn except by tho con
sent of the person who last adjusted the lock.
He alone has possession Of the three magic
numbers which control the whole. In the
largest locks of this pattern there are three
million und three hnMdred MomsGna changes
or combinations. The operator may select any
.L..a f .bo-n nT,yDhnrS Spt The IDpk and
another person might experiment for 4 year,
serhaps q lifetime, without beng able 10 work
out the combination. There are three simple
metallic wheels, called tunble-s, revolving on
the arbor Of the lock, and the operator adopts
a number for each. When numbc. one has
been set in its place by turning the knob for.
number two; then go forward again and
arrange number three. There is no click or
sound to indicate that either tumblcr is right;
the figures or the dial, around the knob, tell
that, and the least variation from the rule will
fail the operator.
SIN short, he must know the three success
sire numbers at which he sets his lock from
within, or he cannot withdraw the bolt. The
change of combinations can dc made hy the
operator at any time when the door of the
vaul. is open, in five minutes, without removing
the lock from the door-but the cover Of the
lock within cannot be removed to make new
combinations by any one who does not know
the numbers on which the lock was last set
This is an ingenious feature, to protect the lock
from thougltless persons who might change
the combinations without authority FROM the
operator.
There are other positive advantages posses
.n1 l,. tht. 1npls p,.nr r,pSt rnu- ~ lEa IL
can be easily understool-in no part
liable to wear outs 50 far within the sale rs
TO be protected from damage by fire il the safe
is exposed to great heat. 1t costs no more than
the best locks in use, and less than many OF
them, and is not liable to break. There is no
KEY to be lost, stolen, or taken hy violence
from the custodian. What better security can
be afforded against burglars or dishonest per-
sons of any kind than this?
''Therc are three patents N this lock, all
within 4 year.
We witnessed the locking and unlocking Of
these safes at the Exchange Bank, and more
perfect machinery was never employed, even in
the most delicate inventions.
The operation Of the present Redemption
Law, locking up the money of thc banks III Sc
cure vaults and safes, is making large sales Of
these valuable safes throughout Virginia. The
