FIRE-ALARM-BOX ATTACHMENT.

Specification-of Letters Patent. Patented-Dec. 21, 1915.

Application filed. May 26, 1915. Serial No. 30,886. v.

To all whom it may concern Be it known that we, AN'roNI CUDosKY and LUDWIKA CUDOSKY, subjects of the Czar of Russia, residing at Passaic, in the county of Passaic and State of New Jersey, have invented certain new and useful Improvements in Fire-Alarm Box Attachments, of which-the following is a specification.

. This invention relates to certain new and useful improvements in fire alarm box attachments.

The primary object of this invention is to provide a device for reducing the number offalse firefalarms in fire alarm systems where street operated alarm boxes are employed.

A further object of the invention is to providethe usual fire alarm box with an attachment whereby .the arm of any person 20" operating the alarm is securely handcuffed until released by an ofiicial of the fire department. I j p A still furthergobject of the invention is to provide an automatic wrist engaging device upon-the door of a fire alarm box which being manually set by the firemen, is automat-ically released by any person turning in an:alarm so that any person who'turns n a false alarm will'be retained at the alarm box until released or arrested by the proper ofiiciali I With; these general objects in view and others that will appear'as the nature of the.

inventionis better understood, the same consists inrthe novelcombina tion and arrange, ment *of parts hereinafter more fully described, illustrated in the accompanying drawings, and pointed out in the appende claims' I In the drawings forming a part of this application and in which like-designating charactersrrefer to corresponding parts throughout-the several views, Figure l is 1 an interior elevational view of the door of i 45 a. fire alarm box provided with the present device, the elements shown in their normal unlocked position. Fig. 2 is a similar viewshowing the elements in their locked positions. "Fig. 3 is an interior view of a fire alarm boxprovided with the present device,

the door being open. Fig. 4 is a horizontal sectional longitudinal view through the fire alarmboxzwhen closed. Figs. 5 and 6are I perspective views of the two wrist-engaging means, and Figs. 7 and 8 are perspective views of the locking racks employed. there-. with.

Referring more in detail to the drawings,

.the present invention is illustrated in connection with a fire alarm box 10 having-a.

hinged door 11, the latter being adapted to be secured in its closed position bymeans.

of a suitable hasp12 engaging over a staple 13. within which a padlock (not shown.) may be inserted. I

Itis to be noted that the alarm boxes-10,- are provided in any number in the fire; alarm system and that a central alarm maybe sounded by operating any one of the boxes, such operation being effected inany desired and well-known manner, such as by completing an electric circuitv between the.

terminals 12 and 13 provided within the:

boxes, such a completion of the circuit being accomplished by swinging a switch. lever; 14

1 by means of a pivoted knob 15 so as to' bridge the said terminals.

The boxdoonll has a front opening 16 therein which is normally covered by aslide l7 pivoted as at 18 within the boxand re siliently retained in its closed position by. means of a coil spring 19. A turn knob20.

is secured upon the outer end of the slidepivot 18 exteriorly of the door 11 whereby the slide maybe opened to the position illus-v trated 1n Fig. 2'against the action of; the

spring 19- and thus allowing the hand tobe "spaced ends 26 attached to compression] springs 27, the opposite ends of the said s rings being secured as at 28 adjacent the,

A latch link 81 is pivoted to across bar 32 of the yoke 25- and is posi- A rack 29is lontioned in abutting engagement with the said lug 29 when the yoke 25 is normally arranged unobstructingthe door andv plate openings and at which time the springs 27 are under tension. 7

A hook shaped wrist engaging member 33 has a curved end 34-slidably arranged v rearwardly of the plate 23 and isslidably positioned underlying theyoke bar 32 and within a strap 35 secured to the door which strap also acts as a guideafor the link 31.

- A-rack 36- is longitudinally secured with- I in th'edoorll and has a stop notch-37 adjacent the outer end and aplurality of teeth o within the notch 37 of the rack 36 when the i hook end 34 is withdrawn from the 'door 3S=upon its upper face. The said hook 33 has an angular 'end 39 adapted for seating opening. A tension spring 40 is secured be: tween the hookend '39 and the bracket 41 carried by the door and upon disengaging the-hook from the notch 37, the spring draws the hook end 39 overthe rack teeth 38until the said end 39 seats within a re t'aining notch 42 adjacent the 'free end of the' said rack36. o I

Y Agperson for instance who desires -to turn in a false alarm fWlll turn the outside knob 20'and open the slide 17 and insert his hand through thedoor opening 16 and plate opening 24 and will grasp the switch knob 15 5 and turn the same for closing the switch of, the alarm circuit, while simultaneously therewith, the rocker lever 34 will be pivotally moved for elevating the lever'finger 46. This; upward movement of ,..the finger 46 =;*1jai'ses" the free end of theyoke link 31,

I thereby releasing the same from the end shoulder- 2W of the rack 29 and whereby the link-end 47 will ratchet over the rack't'eeth 30, the'yoke 25' being moved inwardly of the l door opening by means of thesprings 27.

The yoke members 1 will thus be positioned as shown in Fig. 2 and the'link end 47, thereof, will' e'n'g'a'ge'one ofthe rack teeth 30 opening the door preventing any return movement of the yoke.
