Science Applied to Burglary" would
not have been an Inappropriate name
for an exhibition experiment conducted
at the ST. James hotel In Washington
the other afternoon, says the Post Of
that city. In order to show what the
up to date safe blower could do, sew
eral sheets of chrome steel were 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 cracksman.
There was also on exhibition an cleo
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 and cannot
be affected 10y conspiracy of watchmen
or others. The system can be applied
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 and in

for opening and closing. When ap-
piled to safes. the same are entirely
incloscd 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 patented braided cable consist
ing of thirteen diminutive strands of
separately insulated wires, all braided
together The entire guarded system
Is operated by closed circuit in con
nection with a relay instrument which
controls a local alarm circuit I'm an
alarm bON.
4 chronometrlc 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 live ply drill
proof chrome steel. ls IS by % 10y Is

that II is !he only one for which this
claim can be- substantiatcd. The

pany ownltg this system claims that
It's cabinets are absolutely proof
against this method or any other Of
modern burglary. The experiment was
conducted 10y Mr.. Fred Schrauder OF
the Bankers Electric Protective com
pa g, assisted by MIR. III. o. Megaard.
Among those present were Mr.. j. G..
Moore OF the National Metropolitan
bank, Mr. 4. s. Brice OF the Riggs M.
tional bank and Mr.. John T.. Bergln.
vault, safe and lock expert OF the
United States treasury. All were
greatly pleased with the working Of
the cabinet.
The Chicago postofiice and other
federal buildings throughout the -coun.
try are to be equipped with this sys
tom OF protection. Mr.. Schrauder Will
take the apparatus 10 New Orleans
and attend the National Association Of
Bankers convention Nov. II, IL and
13. Exhibitions OF burning through
steel will be given IN the lobby OF one
OF the hotels there.
