Y. Application June 18, 1935, Serial No. 27,167 2 Claims. (01. 177—378) 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 45 50 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: Fig. 1 is a diagrammatical plan View of a ?re alarm box with my device built in front thereof; Fig. 2 is a diagrammatical elevation of the device shown in Fig. 1, while 10 ' Fig. 3 is a fragmentary diagrammatical front elevation of my device showing the opening through which the hand of the operator may be - inserted, and Fig. 4 is a diagrammatical front elevation of 15 the ?re alarm box to which my device, has been applied, showing my device in an open position.

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. the general shaped members 51. It will be obvi ous that through this operation pin 43, the 10 lower resting channel 45 and the lower half 46 of the marking member will be moved upwardly as indicated by the arrow 14, said lower half 46 riding on the toothed branches 15 of the In a box . upper half 41 until it will arrive into about the 15 31, secured to the disc 32, a coiled spring 39 tends to rotate the post 33 in one direction, the motion thus imparted to the post 33 and its as sociated parts being limited by the pin 39, as 20 will be obvious. position indicated in Fig. 10, the wrist of the user being encircled by the two members in the space 16 by the said members, the upper half 41 being prevented from upward movement by the action of spring 58. 20 The inner end 48 of the arm 3| may operate After the grip 34 and its associated parts just in the slot 4| of an upstanding cylinder 42, being described have been moved downwardly, and the in engagement with the lower end of a slidable end 48 upwardly, the grip 34 will be turned pin 43, normally urged in a downward direc» against the tension of the spring 38 and the 25 tion by the spring 44. A channel shaped sup knife members 36 will carry the channel mem 25 porting member 45 is secured to the top of the bers 51 around against the further tension of pin 43 in which rests in its normal position the the spring 59, away from the stops 39 and El, lower female element 46 of a ring-like marking the rotating of said channel members 51 carry member, adapted to partly encircle the wrist of ing with them the respective wires 62, 54 and the user, the upper male element or half 41 66, 56, respectively, and pulling the pins 53 and 30 whereof is normally arranged in an upper chan 55 from the lower and upper halves 46 and 4?, nel shaped arcuate part 48 secured to the lower respectively, of the marking members and so end of an upper pin 49 being downwardly pressed releasing said halves from their resting chan by the spring 50 in an upper cylinder 5|, se nels 45 and 48, respectively. At the same time, 35 cured to the top 52 of the box 23. said turning of the grip 34, and ultimately of 35 . The lower half 46 of said wrist encircling ring the channel members 51, will exert a pull on the member is normally secured in its resting posi tion in the channel element 45 by a sliding pin 53, secured to and operated by a wire element 40 54, and the upper half 41 of said marking mem-' ber is normally secured in its channel shaped 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 ‘automatically pull the locking pin 80 out of en gagement with the teeth 82 and permit the re 10 moval of the lower member from the upper mem ,3, upper‘arcuate piece‘; a lower spring acting to nor mally hold the lower rod and its connected lower arcuate piece in the lowermost position, each of said arcuate pieces being formed with a channel having ‘a hole in one side thereof; a marker or hand-cuff comprising upper and lower telescop ing parts resting in the respective arcuate pieces and having holes registering with said holes of the arcuate pieces; extensions on said upper part, corresponding holes being provided in the lower 10 ber.
