(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.

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 2,106,849 3 I26, meshing with the gear I24 ?xedly attached. 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 :3 any type of a string so as to actuate the knob 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.
