eration, comparatively inexpensive to manufac
This invention relates to devices for discourag
ing false ?re alarms, and has for its main ob
ject to provide a device of the character men
tioned in which a normally open marking mem
5. ber will close and. lock on the wrist or another
portion of the arm of the operator of a ?re alarm
device, said marking member otherwise permit
ting‘ the actuating of the alarm device and also
the withdrawal of the arm of the operator but
, 10 said marking member remaining closed and
locked on the arm of the operator so' that the
operator himself may not open and remove the
same.
'
It is a well-known fact that an enormous num
15 her of false ?re alarms are sent every year caus
ing great expense to the various communities,
great annoyance and labor to the Various ?re
departments, and danger, harm and injury to the
public by the delays caused in the operation of
20 the ?re forces, and the purpose of this invention
is to provide means whereby every operator of
a ?re alarm box will have a marking device
locked on his arm by which the operator of the
alarm may be recognized. Appropriate author
25 ities like the ?re department, police, etc. in the
district of the respective ?re alarm boxes will be
provided, according to my invention, with means
to open the locked marking member from the
arm of the person giving the alarm, so‘ that peo
30 ple having an honest cause and reason to give
the alarm will not be annoyed, while a person
giving the false alarm will be marked in a con
35
40

spicuous manner and will' be recognized and
caught, so that my invention will detain people
from giving a false alarm.‘
Another object‘ of my invention is .to provide
a device as characterized hereinbefore which will
be harmless in its ‘operation causing no injury
to the person using the same and permitting him
perfect freedom in the operation of the ?re alarm
device as well as leaving the same‘ after the
alarm is given while the marking member may
afterwards be opened and removed, as by‘ a key
carried by the arriving ?remen.
.Still another‘ object of my invention is to pro
vide a device of the type‘ indicated which will
be adapted either to permit access to the alarm
proper or to operate the same’directly, in each
case simultaneously with the operation of the
marking member releasing elements.
Still further objects of this invention will be
apparent as the speci?cation of the same pro
ceeds and among others, I may mention: to pro
vide a device of the character described which
55 will be, simple in constructiomef?cient in op
ture and install and which will be adapted to be
installed in combination with existing ?re alarm
boxes.
In the drawings forming a part of this spec 5
i?cation and accompanying the same:

’
Referring now to the drawings more in detail
by characters of reference, the numeral 20 in
dicates a ?re alarm box in general and the nu
meral 2i indicates my device for preventing false
?re alarms in general, being applied to and in
front of the ?re alarm box proper 20.
The ?re alarm box 20 may be of ‘ any con
struction, well-known in the art and may be op
erated by any means ‘and methods also Well
known in, the art, as for instance, by rotating a
grip or handle 22 (Fig. 4) in the front of the ?re
alarm box proper 20.
My device for discouraging false ?re alarms, in
this embodiment thereof, is housed in a casing
or box 23, hingedly secured to the front of the
?re alarm box 20, as at 24. A spring-operated
latch bolt, 25 is applied to' the rear of the box
40
2
2,121,206
23 being adapted to snap underneath the loop
?re alarm box proper 20 through the latch bolt
26 on the front of the ?re alarm box 29, auto
matically locking my device 2| on the ?re alarm
25 and loop 26, as will be obvious. In case a
person desires to set the ?re alarm box proper
28, he will insert his hand into my device through
the opening 28 and grasp the handle 34, where
upon he will press said handle and the other
end 32 of the arm 3| in a downward direction
until the knife-like elements 36 will engage in
box 28 when the same is in a closed position.
In
the front wall 2'! of my device, 2. preferably cir~
cular opening 28 may be provided through which
the hand of the operator may be inserted into
the inside of the box 23.
To an appropriate part of the bottom 29 of
10 said box 23 is secured an upstanding member
38 on which is pivoted a rocking arm 3!, the
outer end of which is formed into a disc 32 in
which is arranged a rotatable post 33, being
operable by a grip 34 and carrying at its lower
15 end 35 a knife-like wing member 36.

ous that through this operation pin 43, the 10

of the marking member will be moved upwardly

position indicated in Fig. 10, the wrist of the
user being encircled by the two members in the

the action of spring 58.

receiving element 48 by the sliding pin 55 oper
ated by the wire 56, as will be obvious to those
versed in this art.
45
Substantially opposite to and underneath the
rotatable wings or knives 36, wing channels 51
are arranged on a rotatable post 58 at the bot
tom 29 of the box 23,'normally being urged by
a spring 59 in the box 68 in the same direction
50 as said wing knives '36 are urged by their spring
38, its movement being limited by the stop pin 6 I.
A second lower ?exible wire member 62 is en
gaging in an adjustable manner the ?rst men
tioned lower wire 54, as at 63, being guided in
55 the tube '64 and secured to the left hand side
channel member 51, as at 65, and an upper sec
ond ?exible wire 66 is attached to the end of
the ?rst upper wire 56 in a similarly yielding
or adjustable manner and then guided by the
60 tube 61 in a downward direction and its end 68
secured to the right hand rotatable channel
member 51. Finally a third ?exible wire 69 is
also secured to the bottom of the right hand
rotatable channel 51 and is guided upwardly in
tube 18 on the back wall ‘H of the box 23 emerg
ing through an opening 12 to the outside of
said back Wall ‘H, as at 13 (Fig. 4), and there
being attached to the spring operated latch bolt
25, so that the same may be withdrawn through
said wire 69 when said wire is moved in an in
ward direction.
In this embodiment of my device the use and
operation thereof is as follows: Normally the box
23 containing the parts of my false alarm dis
- couraging device is locked on the front of the
Wire 68 and withdraw the latch bolt 25, thereby
releasing the box 23 from the ?re box proper
28. The operator now may swing the box 23
into the open position shown in Fig. 4 with 40
draw his hand therefrom and operate the handle
or rocking grip 22 of the ?re alarm proper 28.
The lower and upper halves 46 and 41 of the
marking member will however be locked to one
another and will remain closed on the wrist of 45
the user, this locking being e?ected by a lock
ing pin 80 (Fig. 12) carried by the lower mem
ber 46 and urged by a spring 8| into engage
ment with the teeth 82 of the upper member 41,
as will be obvious. Said pin will permit an 50
upward riding of the lower member 46 on the
branches 15 of the upper member 41 but prevent
a withdrawal thereof.
Upon the arrival of the ?remen or other au
thorities, provided with an appropriate key, the 55
pin 88 may be released from the teeth 82 and
the lower member 46 removed from the upper
member 41, thereby freeing the wrist of the
user from said marking member.
One form of said key is indicated in Fig. 12, 60
and in this embodiment thereof, an opening 83
is provided in each side of the lower member
46 giving access to the key, generally indicated
by the numeral 84, to the spring pressed hinged
arm 85 carrying the locking pin 88, and said key 65
may comprise a sleeve member 86, a slidable
pin-like member 81 and a coiled spring 88 inter
posed between the sleeve 86 and the head 89
of the pin 81. The outer end 98 of the pin is
turned at right angle into a projection as shown
in Fig. 12. In use, the spring 88 is compressed
by the thumb of the user between the head 89
and the sleeve 86, the projection 98 at the end
of the pin is then inserted into the space 9| in
the respective side of the lower member 46 in
2,121,206
a horizontal position until it reaches beyond the
lower end of the hinged lever or arm 85, where
upon it will be turnedupwardly, as shown in
Fig. 12, so as to catch said lower end of the arm
85 and then the spring 88 released, sleeve‘ 86
being still held’ pressed to the side of the member
49 so that the expansion of the spring 88 will

gagement with the teeth 82 and permit the re
