The Cambria freeman. [volume] (Ebensburg, Pa.) 1867-1938, 1892-03-18

compartment holding TWO IlcT> OF HlA
travs, each. So before closing we have
only to slide the trays into the safes,
and everything is secured"
THAT Is very convenient" the re-
porter acknowledged, and it seems to
be very secure"
All. but that is only the first step
toward security the jcwcler eX-
claimed. We do not put all our money
on one card. You have seen that the
safes are Is strong as they can bc made.
That is all that steel can do for us.
Now we call in electricity TO stand
guard. Each safe is connected by sep
aratc wires with the Burglar Alarm
Company. If an explosion or any other
Jar aGould move one OF thcm six
tc.nth o. an inch ont of its place. "A
b-il would ring in the headquarters Of
tn & company. and within ninety sec
ondss two p lie mon would b. here If
ANYBODY should turn the comhina-
tiou knob 4 hairs breadth that would
have the same effect | used to have
the wires run into my slccpinG-room,
bUt | found that TWO or three times a
year there would bc some trouble with
crossing wires, and l would lie called
out in 4 hurry in the middle OF the
night, and it gave me too much worry.
50 ! had the wires connected with the
burglar Alarm Company, and now
when | go home do not give the goods
another thought"
Mr. Jcwcler here closed the safe
doors and turned the little knob that
locks them.
''Vc can lock or unlock them hun
drcd times a day" ne continued, but
when we once lock them for the night
they are not opened again till next
morning. When set the combination
for the night, just before going home,
! give an electric signal to the burglar
alarm people. and that instant the
alarm Is set. If | should forget any
thing. and should open the safe my
sci. after giving the signal, there
would be two policemen here in a min
ute and half. exactly the same as
though burglar were at work. Now
do you suppose | can go home with an
easy mind?'
PERI city" the reporter assented;
your goods are certainly safe
But that i only the second step to-
ward security" Mr.. Icweler said. Let
me show you the third"
He closed the folding doors of the
walnut cabinet.
Tap one of those panels with your
fingers, please he said
The sound that followed was muffled
and heavy. entirely unlike the sound
made by tapping q thin wooden panel
These slight cabinets are not as de
fcnsclcss as they look" the jeweler
continued Those panels are made Of
pastcboard, and other parts of the cab
incts, although of wood on the outside,
have paateboard within"
And why paste board?" the reporter
asked.
Because paste board is a better non
conductor than wood The panel you
tapped is made of three thiclnesSes of
paStcboard and two thickneSScS of tin
foil. First there is the outer pasteboard
panel. which Is stained and grained To
initiate walnut; then n layer of tin
foil; then a second sheet of paste board;
then a second layer of tin foil; and
finally a third sheet of pasteboard,
which forms the back of the panel
The first sheet of tin foil Is connected
with the positive pole of an electric
battery. the second sheet of tin foil i
connected with the negative pole al a
battery. With the sheet of paste
board between them the metallic
sheet do not touch, and there i. no cir
cult But let burglar begin to opcr-
ate upon the cabinet, and run knife
or Il gimlet or anything else through
the panel. and the metallic tool. touch-
ing both sheets of tin foil, instantly
completes the circuit, Il bell rings in
the burglar alarm office, and two po-
hccmcn come, as before"
is that ALP" the reporter asked
No. not quite Mr. Jeweler smil-
ingly replied. BESIDES these little ap-
plances we have q faithful watchnau
in the store all night. Part or hi
work Is 10 press a little electric button
every half hour from the time we lock
th. front door at night till W. orcn it
in the morning. Thereby he tells the
burEular alarm people that hc Is awake
and ON duty. If he lets sixty seconds
p .yonI the half hour pass without
pressing the button, the two policemen
come to see what Is the matter. Just aS
i aomcbody had tampcrcd with the
safes"
There wer" no more precautions. and
the jcwclcr and the reporter emerged
from the inn or regions Of gold and pre-
ciouS stones.
Thank you very much, '' said the re-
porter.
Good day, said the jcweIer. Come
arIn: but always come in the day
time. ~. Y. sun.
