FIRE ALARM BOX
Robert B. Long, Dayton, Ohio
Application October 2, 1935, Serial No. 43,214
6 Claims. (Cl. 177-379)
This invention relates to a ?re alarm signal
box and more particularly to a removable hand
cuff attachment and the mechanism associated
therewith, adapted for use in a ?re alarm box.
An object of this invention is to provide such
an attachment for ?re alarm boxes that pre
vents the reporting of a false alarm without
determining who turned in the ?re alarm.
Another object of this invention is to provide
10: a device that is cheap, efficient and dependable.
Another object of this invention is to provide
a device that will not permit the reporting of
the ?re by use of mechanical devices instead of
manual manipulation.
With the above primary and other incidental
objects in view, as will more fully appear in the
speci?cation, the invention consists of the‘ fea
tures of construction, the parts and combina
tions thereof, and the mode of operation, or
their equivalents, as hereinafter described and
20 set forth in the claims.
Fig. 1 is a perspective View showing the ?re
alarm box door immediately after the cuff has
been removed.
Fig. 2 discloses an inside View of the door
25., embodying one type of mechanism for releasing
the cuff.
Fig. 3 is a fragmentary View of a portion of
the mechanism at the time that the mechanism
30, is in cuff releasing position.
Figs. 4, 5, and 6 are detail views of the cu?
mechanism, Fig. 6 being shown in section.
Fig. 7 discloses the preferred embodiment of
the cuff releasing dial and the parts associated
35; therewith.

that may be used instead of the mechanism
shown in Figs. '7 and 8.
Fig. 11 is a fragmentary, sectional view of
45‘ another safety device embodied in the modi?
cations shown in Figs. 2 and 9.
Fig. 12 discloses another modi?cation of the
cuff mechanism.
Fig. 13 is a fragmentary sectional view of one
50.‘ side plate and parts associated therewith, taken
substantially on the line l3—-I3 of Fig. 12.
Fig. 14 is a fragmentary view of the actuat
ing mechanism shown in Fig. 9 when moved
to other positions.
55-.‘ In the conventional ?re alarm boxes there is
found a ?re alarm signal mechanism that is
actuated when reporting a ?re. Most of the
mechanism is generally located in a housing
provided with a door having a lever or suitable
actuating mechanism extending therethrough, so
that the ?re may be reported without actually
opening the door.
This however varies, as in
some installations it is necessary to open the
door.
In the accompanying drawings the door 20 is 10
provided with a housing. or enclosure 22 having
an opening at its bottom receiving a handcuff
unit 24 held in position by suitable pins 26. The
handcuff unit 24 disclosed in Figs. 1, 4, 5, and 6
is a removable closure.
It is provided with an 15
opening 28 and is located in the opening below
the closure 22. The unit 24 has a pair of grip
ping jaws 32 and 34 that are released by a suit
able mechanism to be described later, so as to
grip the wrist of the operator as he turns the
knob mechanism 40, whereby the one reporting
the ?re carries the cuiT unit 24 on his wrist until
the gripping jaws 32 and 34 are released, as fully
described in my copending application Serial
Number 607,116, ?led April 23, 1932, for a Fire
alarm box attachment, now Patent Number
2,020,279, granted Nov. 5, 1935.
"
Referring to Fig. 2, wherein the inside of the
door has been disclosed, the actuating mecha
nism includes a lever 42 pivotably mounted on 301
the door at 44. This lever 42 supports a pin
46 upon which is rotatably mounted a sleeve
48 supporting a cam 50 ?xedly attached thereto.
As the knob 40 rotates the cam 50 in a counter
clockwise direction through a suitable driving 35
mechanism which will be described later, the
lobe 52 engages a stationary pin 54 which urges
the cam’ 50 to actuate the lever 42 in a clock
wise direction as viewed in Figs. 2 and 3 about
the pivot 44‘ against the spring 56. As the cam 40
50 is rotated in a counter-clockwise direction it
releases detent member 60 pivotally mounted at.
62, permitting the spring 64 to actuate member
60 inv a counter-clockwise direction, as viewed
in Fig. 2, thereby causing the projection 66 to 45?
release the cuff, as disclosed in my copending
application.
In some types of boxes it is necessary to open'
the door in order to reset the ?re alarm signal
transmitting mechanism. In others'the opening 50
of the door automatically transmits the signal.
In the modi?cation disclosed in Fig, 2, the latch
12 normally opened by the insertion of a‘key'
in the lock" shownon the front side-of the
door, as viewed" in Fig. 1, or by any suitable 5'5
2
(.1
2,106,849
handle or latch is automatically released when
been found that normally a person will actuate
the cam 50 is actuated, so as to release the
member 94 a limited distance but will not lock
detent 60. This is accomplished by a bell crank
lever 16 pivotally mounted at 18 having one arm
should p-erchance lock the mechanism. momen
80 mounted for engagement with the projection
84 of member 60, so as to rotate the bell crank
member 18 in a counter-clockwise direction, as
viewed in Fig. 2, causing the pawl 82 seated
in a suitable recess in member 12 to release it,
10 thereby permitting the door to be swung into
open position whenever the handcuff unit 24 is
released.
If the signal is transmitted in response to the
release of the cuff unit 24, the door is automati
15 cally unlocked to permit the ?remen to reset the
box.
If a system is used wherein the box must
be opened when relaying the signal, the cuff unit
24 will automatically lock itself on the reporter’s
wrist whenever the knob 40 is actuated to open
20
the door.
I
As may be best seen in Fig. 5, the jaws 32
and 34 preferably of tool resisting material, have
been lined with heat insulating material 86 and 88
such as vulcanized rubber, so that if the reporter
of a ?re happens to report a ?re during extremely
cold weather and his arm happens to be moist,
the jaws will not freeze to his arm. This is found
necessary for the safety of those reporting the
?res. A tubular sleeve 90 is mounted below the
opening 28 and is equipped with a resiliently
biased closure 92 normally in closed position to
prevent birds, bees and the like from forming
nests within the housing 22. Furthermore, the
sleeve 90 and the closure 92 keep dust and foreign
matter from accumulating in the box.
It is conceivable that a person might insert a
suitable object, such as a short pipe, a metallic
casing in the opening 28,0r a pair of clamps en
gaging the jaws to prevent movement thereof,
40 and then pass the arm through this opening to
turn in a false ?re alarm‘, the jaws 32 and 34
the mechanism.
Furthermore, if the operator
tarily in attempting to rotate the knob 40, the
operator would in all probability release» the pres
sure upon member 94 suf?ciently long to permit
the parts to operate. On the other hand, if a
person tampering and attempting to turn in a
false alarmv inserts a pipe or some other foreign 10
article into the opening 28 so as to prevent the
jaws 32 and 34 from snapping into closed posi
tion, such a person would in all probability actu
ate member 94 sumciently far to lock the mecha
nism. Certainly this would be the case in- the 15
event that instead of a pipe, clamping jaws were
inserted in opening 28. This would prevent the
jaws 32 and 34 to close upon the operator’s arm.
The clamping jaws thus inserted would actuate
member 94 in a clockwise direction, as viewed in 20
Fig. 5, so as to lock the mechanism. Member 94
is provided with a rubber facing I20 for the same
reason as the facing is placed upon the jaws 32
and 34.
When a knob like that disclosed in my copend 25
ing application Serial No. 607,116 is used, it is
conceivable that a person desiring to turn in a
false alarm-might remove his belt and use it to
drive the knob without inserting his arm into
the opening 28, thereby defeating the purpose of 30
the cuff unit 24, which would permit the violator
to escape without any obstructions. To eliminate
this difficulty the knob 40 is rotatably mounted
upon a pintle I22 ?xedly attached to member 42.
The knob is ?xedly attached to a gear I24 also 35
rotatably mounted upon. the pintle I22 and mesh
ing with a gear I 20 ?xedly attached upon a. stub
shaft I28 journaled in a shield I30 and driving
a gear I32 meshing with a gear I 34 ?xedly at
tached upon a tubular sleeve I36 driving the cam
arm through the opening and escaping without
50. The shield I38 is mounted for vertical move
ment in the guides I 38 ?xedly attached to the
Wall of the door 20, so that the shield may have
the cuff unit 24. In order to overcome this di?i~
substantially vertical movement with the cam 50. .
engaging the object, the operator slipping his
45 culty a lever 94 pivoted at 96 and biased in a
counter-clockwise direction, as viewed in Fig. 5,
by a suitable spring 98 normally projects a short
distance into the opening 28 and has limited
normal movement. This member 94 is preferably
50 located below the knob or dial side of the ?re
alarm system. Referring to Fig. 11, a detent I00
integral with member 94 is aligned with the
opening I02 and with a pawl I04, so that as mem
ber 94 is actuated in a clockwise direction, as
55 viewed in Fig. 5, the detent I00 will urge the pawl
I04 to the left, as viewed in Fig. 11. The detent
I04 pivotally mounted at I06 and urged in a
counter-clockwise direction, as viewed in Fig. 11,
is provided with an extension I I0 that limits the
60 movement of a pivotally mounted arm II2 to
prevent the operation of the ?re signalling device
and the release of the handcuff when thus locked.
By referring to Fig. 2, the latch arm I I2 is pivot
ally mounted vat H4 and provided with a dog
65 H6 normally seated against member 58. As
best seen in Fig. 2,..the latch H2 is urged in a
counter-clockwise direction by a spring II8.
Whenever the extension I I0 of the pawl I04 locks
member II2 so as to prevent it from rotating
70 in a clockwise direction about the pivot II4, it
is impossible to rotate the cam 50 and to actuate
the parts associated therewith. Thus, it will be
seen, that if the operator inserts his arm into the
opening 28, member 94 may move a limited dis
75 tance without locking the mechanism.
It has
The face of the shield I30 is cut away at I40 so
as to expose oppositely disposed portions of the 45
knob 40. As may best be seen by referring to
Fig. 8, the knob 40 is preferably split and pro
vided with an annular groove 542 in the periphery
thereof, into which extend diametrically ar-'
ranged members I44 and I46 which obstruct the
contour of the knob assembly 43. Members I44
and I48 are ?xedly attached to the shield I30 and
5.0
move therewith.
Referring to the modi?cation disclosed in Figs. 65.
7 and 8, the shield for the gears is supported upon
member I22 and moves up and down through a
slightly arcuate path in response to the reporting
of a ?re. Referring to Fig. 9 for example, the
cam 50 is precluded from moving downwardly by 60
a pin located below this cam. This is more fully
explained in the Long Patent No. 2,020,279.
However, as the cam 50 is rotated the lobe 52
engages the pin 54, at which time the notch in
the cam below the pivot 46 is rotated sufficiently 65
so as to register with the pin below the cam,
allowing the cam to move downwardly. As the
cam moves downwardly, the shield and the gears
mounted in the shield also move downwardly in
unison with the cam 59. in the Long patent the 70
cam 40 mounted upon member 31 was rotated
by turning the knob II). In the present modi?
cation the knob I0 has been removed and the
gear I34 substituted therefor. This gear meshes
with the gear I32 ?xedly attached to the gear 75

port of the mechanism. As members I 60 and
to the knurl knob 40, so that as the operator‘
rotates the knurl knob 40 the cam 50 in the appli
cation is rotated through the train of gears.
From the foregoing it may readily be seen that
it is practically impossible to insert a cord, a belt

I68 'are actuated from the dot-dash position
shown in Fig. 14 to the full line position, the
In order to preclude the use of a stick or some
10 other rigid member inserted through the open
ing 28 to engage the exposed portions of the
knob 40, a ledge or shelf I50 ?xedly attached to
the support of the guides I38, obstructs the path
between the knob 40 and the opening 28. Thus,
15 it will be seen, that in addition to preventing the
use of a belt and the like for falsely reporting a
?re, the use of a stick or any other rigid mem
ber for the operating of the knob 40 is prevented.
In Fig. 10 a knob I50 has been shown instead
20 of the knob 40 and the gears driven thereby to
gether with the knob. This knob I 50 is provided
with a substantially bell-shaped locking member
I52 pivotally mounted at I54 and’normally urged
in a counter-clockwise direction‘ by a spring I56
25 as viewed in Fig. 10. In normal position the
arcuate arm I58 of the bell crank'lever I52 is
?ush with the periphery of the knob, a portion
of which has been cut away to accommodate the
arcuate surface of member I58. The other arm
30 of the bell crank lever I52 normally engages a
notch in the pintle I22 so as to prevent rotation
of the knob I52 without the ?ngers of the oper
ator actuating the bell'crank lever I52 in a coun
ter-clockwise direction from the full line position
35 to the dot-dash position in Fig. 10. When the
operator actuates the bell crank lever from the
full line position to the dot-dash position the
cam I 80 retracts or urges member I68 to the
left, as viewed in Fig. 14 against the force of the
spring III to release the latch I62 when the actu
ator, which has not been shown, has been moved .
to its full stroke. Members I60 and I68 may be
actuated in a clockwise direction about the pivot
I18 by an adjustable link I12 pivotally mounted 10
at I14 to member 60.‘
> By adjusting the length of the arm I12, which
is preferably made of two sectors, one of which
is provided with a slot I16, the position of mem
ber I68 may be further adjusted. In addition 15'
to member I62 actuating the signal transmitting
device, the arm I90 may be provided with a suit
able signal actuating member I94 that is prefer
ably mounted on member I90. When a type box
is used where member I94 actuates the signal 20
transmitting device, the rod I12 may also be ad
justed to satisfy the requirements of the system.
In order to keep member I68 con?ned within a
predetermined path, a retaining member 200 ?x
edly attached at 202 and 204 to member I69 25:
limits the transverse movement of the arm I68.
In resetting the above described mechanism,
member 60 is preferably rotated in a clockwise
direction by a suitable Wrench or tool, not shown,
which rotates member I60 in a counterclockwise
cation has been shown,.disclosing a device com
arm is released from the notch in member I22
so as to permit free rotation of the knob I52.
40 If a belt is used by the operator to turn in a
plementing I20 in preventing the manipulation
of the ?re alarm signal system without the cuff
arcuate arm I58 sufficiently to release the latch,
thereby preventing the reporter of a false alarm
from manipulating the ?re alarm signal system
edge of the operation of the device may hold his
arm rigidly against the free ends of the jaws of
the cuif shown in Fig. 5. If su?icient force is
applied to the jaws, the jaws may be hindered
from engaging the operator’s arm and thereby
permitting the operator to slip his arm and hand
through the cuff. A member 200 shown in full
line position in Fig. 12 is slidingly mounted in
the casing of the cuff underneath member 94, as
shown in Fig. 13. This member 200 supports a
pin 202 projecting through a slot 204 diagonal
false alarm, such a belt will not depress the
45 by use of a belt, cord, string or the like.
In the modi?cation disclosed in Figs. 2 and 3
the extension I60 of member 42 is used to actu
ate the signal transmitting mechanism which has
not been shown. It has been found that various
types of ?re alarm boxes are in use, some of
50
which may have the signal transmitting mech
anism located elsewhere. In order to provide
actuating mechanism that is adaptable tola great
variety of boxes the mechanism disclosed in the
modi?cation in Fig. 9 may be used.
In this modi?cation in addition to member
42 being used as shown in the modi?cation in
Fig. 3, a member I60 is pivotally mounted at I10
and pivotally supports a latch I62 at I64. A
60 member I68 provided with a slot I69 is also
mounted upon the pivot I10; but may move
through a limited longitudinal movement.
Member I68 is constantly urged to the right, as
viewed in Fig. 14, by a spring I1 I, having one end
attached to a stud I13 ?xedly attached to mem
ber I68 and the other end mounted upon the
stud I15 ?xedly attached to member I60 and
projecting through a slot I11 in member I 68,
the stud I15 cooperating with the pivot I10 to
70 permit member I68 to‘ have a predetermined
movement with respect to its support I60. A
stud I19 carried by member I68 is engaged by a
cam I80 having its center at I10 and held in a
rigid position by a screw I84 threadedly engag
ing a bracket I8I ?xedly attached to the sup
30 I.
direction about the pivot I10 into the dot-dash
position shown in Fig. 14. The latch I62, which
was released during the clockwise movement of
member I60, may then be actuated into the dot
351
dash position shown in Fig. 14.
Referring to Figs. 12 and 13 another modifi
engaging the wrist of the operator. It is con
ceivable that a person having a thorough knowl
40
ly arranged in member 206, pivotally mounted
upon the pivot 96.. If member 200 is actuated
to the left, as viewed in Fig. 12, into the dot-dash .
position, the pin 202 cooperating with the slot
204 actuates members 206 in a clockwise direc
tion about the pivot 96, causing the detent 208
to ‘actuate member I04 shown in Fig. 11 into
locking engagement to lock member I I2, thereby 60
preventing the release of the signalling mech
anism. Member 200 is normally urged to the
right, as viewed in Fig. 12, by a suitable spring
2I0.
From the foregoing it is apparent that if an 65
operator tries to insert a cylindrical member to
prevent the cuff from engaging the wrist of the
violator, member 94 will in all probability be ro
tated in a clockwise direction so as to lock the
mechanism, preventing the transmission of the 70
signal. Likewise, if the operator should attempt
to urge his arm against the ends of the jaws he
would actuate member 200 into dot-dash posi
tion shown in Fig. 12, thereby preventing the re
porting. of the signal. In. either event, the cuff 75
4
2,106,849
would not be released and the falsereport would
not be transmitted. Anyone attempting to report
a ?re would normally insert the arm through the
opening 28 without actuating members 94 and
200 to lock the mechanism. If,,perchance, the
mechanism would be momentarily locked, the re
porter of a ?re in attempting to manipulate the
lock would in all probability move the arm into
such position as to release the mechanism, there
10 by permitting the reporting of the ?re. Thus, it
may be readily seen that a person attempting to
defeat the operation‘ of the cuff would be pre
cluded from operating the ?re alarm mechanism,
whereas a person desiring to report a ?re, if he
15 accidentally locked the mechanism, would in all
probability release the locking mechanism in at
tempting to actuate the ‘fire signal transmitting
device.
From the above description it will be apparent
20 that there is thus provided a device of the char
acter described possessing the particular features
of advantage before enumerated as desirable, but
which obviously is susceptible of modi?cation in
its form, proportions, detail construction and ar
25 rangement of parts without departing from the
principle involved or sacri?cing any of its advan
tages.
'
'

invention has been described in language more or
30 less speci?c as to structural features, it is to be
understood that the invention is not limited to
the speci?c features shown, but that the means
and construction herein disclosed comprise the
preferred form of several modes of putting the
