"A FOIL FOR CRACkSMEN
Electrical Safe Covering Claim
ed to be Burglar Proof.
oAN BE ALSO APPLIED TO VAULTS

Cabinet shown at an Exhibition Ex-
periment which Is Snid to Resist
Such Methods as Burning Six Lay
ers of Chrome Steel Through In
Two Minutes and "a Quarter.
"Science Applied to Burglary would
not have been ali inappropriate haLhe
for an exhibition experiment conducted
at tho ST lanes hotel in Washington
the other afternoon, says the PoSt Oh
that city. In order to show what the
I'M to date safe blower could do, sew
eral sheets of chrome steel We're burned
through by searchlight carbon at
tached TO an electric current, thus
demonstrating that the great bank
vaults are not altogether secure from
the assaults of the craftsman.
There was also on exhibition an elcc-
trical cabinet which is built for the
purpose of covering safes, making
them absolutely proof against burglars
and the electric current above men
toned. The apparatus is entirely me-
chanical in its operation ana cannot
be affected by conspiracy OF watchmeh
or others. The system can be apphed
to safes or vaults also furnishing
protection against day raids. When
applied to vaults, they are electrically
lined internally, having the vault doors
covered externally with quarter sawed
oak doors and frames, supplied with
electric lining, contact points ana IN
dictator. showing condition of the cur
rent at all times and serving as guide
for opening and closing. When APP
Dlied to safes. the same are entirely
inclosed externally with quarter sawed
oak cabinets, with front doors all cleo
trically lined.
The lining forms two complete cir
cults and is connected to the alarm box
by a patented braided cable, consist
ing of thirteen diminutiye strands OF
separately insulated wires, all braided
together. The entire guarded system
is operated by a closed circuit in con-
nection with relay instrument, which
controls a local alarm circuit in an
alarm box.
A chronometric time lock and bat
teries from which the current is de-
rived are located in a vault or guarded
structure. The alarm box is most sub
stantially constructed of five ply drill
proof chrome steel, is SO by % by IS
inches, electrically lined, contains re-
lay instrument, polariZed switch, bat
teries and the eighteen inch diameter
gong. 1t is carefully protected against
any atmospheric influences and may
be located as desired. The usual CHS
tom is to place it in front of the bank
building
All relay and indicator instruments
are made with jewel bearings and
phosphor bronze springs. Any inter
ference at any point of the system in
any way will cause an alarm to sound
at once, which can be heard at a great
distance The system can be connect
ed with other points besides the alarm
box. 1t is claimed that it is a physical
impossbility to defeat the system and
that it is the only one for which this
claim can be Substantiated The
working of the system is guaranteed
from year to year.
A DOle lE2 iHcueS III uldlHeleI was
burned through six layers of chrome
steel in two minutes and fifteen Sec
Onds. The apparatus for this purpose
weighs but twenty pounds, and the
carbon may be attached to any ordi-
nary arc light electric wire. The com
pany owning this system claims that
its cabinets are absolutely proof
against this method or any other of
modern burglary. The experiment was
conducted by Mr.. Fred Schrauder of
the Bankers Electric Protective COM
pany, assisted by Mr. H. o. Megaard.
Among those presently Mr.. j. G.
Moore of the National Metropolitan
bank, Mr.. A. S. Brice of the Riggs Ma
tional bank and Mr.. John P. Bergin,
vault, safe and lock expert of the
United States treasury. All were
greatly pleased with the working OF
tAe cabinet.
