55-. In the conventional fire alarm boxes there is found a fire alarm signal mechanism that is actuated when reporting a fire. 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 fire 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 gripping jaws 32 and 34 that are released by a suitable 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 fire 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, filed 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 mechanism includes a lever 42 pivotably mounted on 1 the door at 44. This lever 42 supports a pin 46 upon which is rotatably mounted a sleeve 48 supporting a cam 50 fixedly attached thereto. As the knob rotates the cam 50 in a counterclockwise 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 clockwise direction as viewed in Figs. 2 and 3 about the pivot 44 against the spring 56. As the cam 4 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 in a counter-clockwise direction, as viewed in Fig. 2, thereby causing the projection 66 to 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 fire alarm signal transmitting mechanism. In others'the opening of the door automatically transmits the signal. In the modification disclosed in Fig, 2, the latch 12 normally opened by the insertion of akey' in the lock" shownon the front side-of the door, as viewed" in Fig. 1, or by any suitable 5'5 handle or latch is automatically released when the cam 50 is actuated, so as to release the detent 60. This is accomplished by a bell crank lever 16 pivotally mounted at 18 having one arm 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, 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 automatically unlocked to permit the firemen 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 reporters wrist whenever the knob 40 is actuated to open 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 fire happens to report a fire 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 fires. A tubular sleeve 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 engaging the jaws to prevent movement thereof, and then pass the arm through this opening to turn in a false fire alarm, the jaws 32 and 34 engaging the object, the operator slipping his arm through the opening and escaping without the cuff unit 24. In order to overcome this difliculty 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 located below the knob or dial side of the fire 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 member 94 is actuated in a clockwise direction, as 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 movement of a pivotally mounted arm II2 to prevent the operation of the fire signalling device and the release of the handcuff when thus locked. By referring to Fig. 2, the latch arm I I2 is pivotally mounted at H4 and provided with a dog 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 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 distance without locking the mechanism. It has been found that normally a person will actuate member 94 a limited distance but will not lock the mechanism. Furthermore, if the operator should p-erchance lock the mechanism. momentarily in attempting to rotate the knob 40, the operator would in all probability release the pressure upon member 94 sufficiently long to permit the parts to operate. On the other hand, if a person tampering and attempting to turn in a false alarm inserts a pipe or some other foreign article into the opening 28 so as to prevent the jaws 32 and 34 from snapping into closed position, such a person would in all probability actuate member 94 sumciently far to lock the mechanism. Certainly this would be the case inthe 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 operators arm. The clamping jaws thus inserted would actuate member 94 in a clockwise direction, as viewed in 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 copending 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 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 fixedly attached to member 42. The knob is fixedly attached to a gear I24 also rotatably mounted upon. the pintle I22 and meshing with a gear I 20 fixedly attached upon a. stubshaft I28 journaled in a shield I30 and driving a gear I32 meshing with a gear I 34 fixedly attached upon a tubular sleeve I36 driving the cam 50. The shield I38 is mounted for vertical movement in the guides I 38 fixedly attached to the Wall of the door 20, so that the shield may have substantially vertical movement with the cam 50.
The face of the shield I30 is cut away at I40 so as to expose oppositely disposed portions of the knob 40. As may best be seen by referring to Fig. 8, the knob 40 is preferably split and provided 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 fixedly attached to the shield I30 and move therewith.
Referring to the modification disclosed in Figs. 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 fire. Referring to Fig. 9 for example, the cam 50 is precluded from moving downwardly by 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 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 cam 40 mounted upon member 31 was rotated by turning the knob II). In the present modification the knob I0 has been removed and the gear I34 substituted therefor. This gear meshes with the gear I32 fixedly attached to the gear 7 I26, meshing with the gear I24 fixedly attached to the knurl knob 40, so that as the operator rotates the knurl knob 40 the cam 50 in the application 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 In order to preclude the use of a stick or some other rigid member inserted through the opening 28 to engage the exposed portions of the knob 40, a ledge or shelf I50 fixedly attached to the support of the guides I38, obstructs the path between the knob 40 and the opening 28. Thus, it will be seen, that in addition to preventing the use of a belt and the like for falsely reporting a fire, the use of a stick or any other rigid member for the operating of the knob 40 is prevented.
In Fig. 10 a knob I50 has been shown instead of the knob 40 and the gears driven thereby together with the knob. This knob I 50 is provided with a substantially bell-shaped locking member I52 pivotally mounted at I54 andnormally urged in a counter-clockwise direction by a spring I56 as viewed in Fig. 10. In normal position the arcuate arm I58 of the bell crank'lever I52 is flush 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 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 fingers of the operator actuating the bell'crank lever I52 in a counter-clockwise direction from the full line position 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 arm is released from the notch in member I22 so as to permit free rotation of the knob I52. If a belt is used by the operator to turn in a false alarm, such a belt will not depress the arcuate arm I58 sufficiently to release the latch, thereby preventing the reporter of a false alarm from manipulating the fire alarm signal system by use of a belt, cord, string or the like.
In the modification disclosed in Figs. 2 and 3 the extension I60 of member 42 is used to actuate the signal transmitting mechanism which has not been shown. It has been found that various types of fire alarm boxes are in use, some of which may have the signal transmitting mechanism located elsewhere. In order to provide actuating mechanism that is adaptable to a great variety of boxes the mechanism disclosed in the modification in Fig. 9 may be used.
In this modification in addition to member 42 being used as shown in the modification in Fig. 3, a member I60 is pivotally mounted at I10 and pivotally supports a latch I62 at I64. A 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 fixedly attached to member I68 and the other end mounted upon the stud I15 fixedly attached to member I60 and projecting through a slot I11 in member I 68, the stud I15 cooperating with the pivot I10 to 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 engaging a bracket I8I fixedly attached to the support of the mechanism. As members I 60 and I68 'are actuated from the dot-dash position shown in Fig. 14 to the full line 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 actuator, 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 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 member I68 may be further adjusted. In addition to member I62 actuating the signal transmitting device, the arm I90 may be provided with a suitable signal actuating member I94 that is preferably mounted on member I90. When a type box is used where member I94 actuates the signal transmitting device, the rod I12 may also be adjusted to satisfy the requirements of the system. In order to keep member I68 confined within a predetermined path, a retaining member 200 fixedly attached at 202 and 204 to member I69 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 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 dotdash position shown in Fig. 14.
Referring to Figs. 12 and 13 another modification has been shown,.disclosing a device complementing I20 in preventing the manipulation of the fire alarm signal system without the cuff engaging the wrist of the operator. It is conceivable that a person having a thorough knowledge 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 suflicient force is applied to the jaws, the jaws may be hindered from engaging the operators 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 diagonally 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 direction 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 preventing the release of the signalling mechanism. 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 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 rotated in a clockwise direction so as to lock the mechanism, preventing the transmission of the 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 position shown in Fig. 12, thereby preventing the reporting. of the signal. In. either event, the cuff would not be released and the falsereport would not be transmitted. Anyone attempting to report a fire 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 reporter of a fire in attempting to manipulate the lock would in all probability move the arm into such position as to release the mechanism, thereby permitting the reporting of the fire. Thus, it may be readily seen that a person attempting to defeat the operation of the cuff would be precluded from operating the fire alarm mechanism, whereas a person desiring to report a fire, if he accidentally locked the mechanism, would in all probability release the locking mechanism in attempting to actuate the fire signal transmitting device.
From the above description it will be apparent that there is thus provided a device of the character described possessing the particular features of advantage before enumerated as desirable, but which obviously is susceptible of modification in its form, proportions, detail construction and arrangement of parts without departing from the principle involved or sacrificing any of its advantages.
