page_text: Referring to Fig. 4, which is a diagrammatic view of the safe-connections,
12 shows the main battery which may be of any of the constant closed circuit
types, and 13-14 are the conductors leading therefrom; the conductor 13 has no
connection with the safe, but continues on past it to the alarm box 15.
The conductor 14, however, passes up behind the safe and in the path of a
contact-stud 16 fixed in the back of the box and terminates in a spring contact
arm 17 located in the path of a switch 18.
The circuit extends through said switch to the opposite spring-contact 19 and
conductor 20, across the path of the contact-stud 21, fixed in the back of the safe,
thence over the conductor 22 to the alarm-box.
From the stud 16 in the back of the safe, a conductor 23 extends to a switch-
point 24 fixed on the door of the safe and from said point 24 over a conductor 25
to a spring contact-point 26 fixed on the top of the safe and in the path of the
door 2.
27 represents a similar contact-point fixed in the top of the safe and in the
path of the point 26; and from it à conductor 28 extends to the switch-point 29
and thence over a conductor 30, to the contact-stud 21, before mentioned.
The switch 18 is fixed in the back wall of the recess in which the safe is located,
and it is provided with a square shank 31 which extends through an aligned
orifice in the back of the safe and by means of a suitable key the switch'is operated
from the inside of the box.
Referring to Fig. 6, the circuit extends over the conductor 13 through the
electro-magnet 32 and from the non-magnetic contact point 33 in its core to its
armature 34, and through said armature to the conductor 22 which completes the
closed circuit of which the battery 12 and the safe 1 form a part, and when this
circuit is closed, and which is its normal condition, the magnet 32 is energized or
charged to hold the armature in contact with it, if however, the circuit be broken
at any point, the retractile spring 35 withdraws the armature from the core, and
it remains in this position until the circuit is closed where it was originally opened
and also at this point which of course, must be done by hand. by moving the
armature up to the magnet and closing the circuit through the armature and
contact point 33.
36 represents an adjustable contact screw fixed in the path of the back of 'the
armature 34, and from said armature a conductor 37 extends to one' pole of an
ordinary even circuit battery 38, and from the opposite pole a conductor 39 extends
to the binding post 40, of an ordinary vibrating bell 41 located wholly within the
box 15.
42 represents the opposite binding post of said bell 41 and from it a conductor 43"
extends to a switch-lever 44, arranged to make contact with a plate 45 fixed in
its path.
From said switch lever 44 a conductor 46 extends to the binding post 47 of a
second vibrating bell 48, also located within the box 15; but its hammer arm '49"
extends through an orifice 50 in the front 51 of said box 15, to sound an alarm on
the gong 52, fixed on the outside of the box.
From the opposite post 52 of said bell 48, a conductor 53 extends to the post 40 4
of the bell 41 first mentioned, and from the switch plate 45; a conductor 54 extends
to the contact-screw 36, and which completes the local or alarm circuit.
It will thus be seen that if the main or closed circuit in which the safe is located
as heretofore described, be interrupted, the armature 34 will be released'
and its spring 35 will draw it back and close the local circuit through the screw 36:5
The front of the box 15 is provided with a "Yale" lock 55; and by means of a
switch-lever 44, the local circuit may be broken when for any reason it shall no
not
be desirable for it to operate. This switch-lever 44 is connected to the barrel of
a "Yale" lock extending through the front of the box and of course, it can only
be manipulated from the outside by means of its 'appropriate key."
5
The gong 52 as heretofore stated; is located on the outside of the box 15, so as
to sound an alarm within a considerable radius of the box, but should' said g
gong

page_text: be surreptitiously removed or silenced, the bell 41 would still continue to ring as
it with its battery and connections is located wholly within the box and the whole
is proof against any unauthorized interference. In some instances I include the
box 15 and its front or door, in the closed or safe circuit, so that an attempt to
force the door would interrupt the circuit the same as if the safe were tampered
with and start the alarm.
In the diagrammatic view shown in Fig. 4, provision is made for an auxiliary
alarm box 55 which is identical in construction with the alarm box 15 of which
it is a duplicate, and it forms a part of the main or closed circuit in the same
manner.
•
This auxiliary alarm may be located at the watchman's post in a building, a
police station or in fact any point where there is an attendant constantly on duty.
It will be understood that the alarin' or open circuit is entirely protected and
concealed within the alarm boxes 15 and 55, while the closed or safe circuit may
with its battery, be exposed and any tampering with the battery, conductors, or
safe that would interrupt said circuit, if only for an instant will sound the alarm,
which will continue ringing until the alarm circuit is broken, and the safe circuit
closed by the mechanical closing of the armature 34 in the alarm box. It will
also be noted that the conductor's 57 and 58 by which the auxiliary box 55 is in
series with the box 15, are a part of the closed circuit, and consequently if said
conductors 57 or 58 be cut or broken, the local battery in the auxiliary box 55
will be closed and its alarm sounded the same as if the' conductors 13-14-22
were cut or broken.
Referring to Fig. 5, it will be seen that when the safe 1 is in place, the
conductor 14 22 is open at the points 17 and 19, but closed through the
studs 16-21, in the safe.
59 represents a switch-lever on the inside of the door, and it is operated by the
barrel of an ordinary "Yale" lock 60, so that when the rightful party desires
access to the safe, he first turns the switch-lever 59 to close the circuit between
the points 24-29, and consequently cut the circuit breaker 26-27 so that the
safe door 2 may be opened by its key 61 in the usual manner without interrupting
the circuit or sounding the alarm after the door of the safe is closed, the
switch 59 is then turned as before, to cut in the circuit breaker 26-27, should an
attempt be made to forcibly remove the safe from its recess in the wall of the
building or other structure in which it is located, the circuit would be broken at
either or both of the studs 16-21, and the 'alarm sounded as heretofore described.
If, however it is desired to legitimately remove the safe for any purpose, the door
is first opened in the usual manner, a suitable key inserted on the stud 31 and the
switch 18 turned so as to close the circuit between the points 17 and 19, thereby
cutting out the safe which may then be removed without interrupting the circuit
or sounding the alarm.
Although I have specifically described the construction and relative arrange-
ment of the several elements of my invention, I do not desire to be confined to the
same, as such changes or modifications may be made as clearly fall within the
scope of my invention, without departing from the spirit thereof.
In practice, it will be understood that while the alarm boxes 15 and 55, are
made of chilled steel and are practically burglar proof, the safe itself is, as far as
possible, both burglar and fire proof, being formed of chilled steel with any
suitable heat resisting lining, so as to preserve the contents in case of fire.
Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performed, I declare that what
I claim is: -
1. A safe protection system, comprising a closed electric circuit, a safe forming
component part of said circuit, and means as described for sounding an alarm
upon the interruption of the said circuit, as and for the purpose set forth.
2. A safe protection system, comprising a closed electric circuit, a safe arranged

a component part of said circuit, and means for cutting said safe out of the circuit
from the interior of the safe, so that the latter may be removed from the circuit
without sounding the alarm, as and for the purpose set forth.
8. A structure provided with a recess, retaining lugs 9-9 fixed in the walls of
said recess, a safe adapted to engage said recess, a series of spring pawls fixed to
