. FIRE-CONTROLLING APPARATUS.

Application. filed September 1, 1920. Serial To. .0",387.

To all whom it may concern:

Be it known thatl, EFREM Mir-rALoviorI, a citizen of Russia, residing at Chisholm, county oi St. Louis and State of Minnesota,

have invented certain new and useful Improveinents in Fire-Controlling Apparatus, of which the following is a specification.

This invention has as its object the provision of means whereby the location of a be readily ascertained, and audible and visible signals given calling attention to the occurence in anetfeetive manner.

A further object is to provide means for opening a spray head in the compartment in which the fire occurs soas to present a spray of water adapted to quench the fire and thereby prevent damage from being done. I

These and other like objects are attained by the novel construction and combination of parts hereinafter described, and shown in the accompanying drawings, forming a material part of this disclosure, and in which- Figure 1 is a sectional plan view showing a conventional type of building, having a plurality of compartments and indicating the application of the apparatus.

Figure 2 is a side elevational view showing a visible signal means and the operating device connected therewith.

Figure 8 is a side elevational view of one of the audible signal devices.

Figure l is a vertical sectional view taken on line 4& of Figure 5, ot'the spray dispensing device.

Figure 5 is a similar vertical sectional view taken on line 55 of Figure 4, showing the parts in another plane.

4 igure 6 is a fragmentary side elevational view showing an auxiliary type of audible signal.

Figure 7 is a top plan view of the parts shown in Figure 3.

Figure 8 is a top plan view of the auxiliary audible signal means, and

Figure 9 is a longitudinal sectional view taken on line 9-9 of Figure 8.

Referring to the drawings in detail, the numeral 10 indicates the front wall of a conventional type of building, containing windows 11, and having a plurality of interior partitions 12, forming compartments or rooms 13.

Extending inward from the rear wall 14-. of the building are eyes 15 the same being tire within a compartmented building may vers being normally impelled forward, due

to the effect of fiat springs 21 in the manner best indicated in Figure 2. I

Mounted in the levers 19 are flag staffs 23, carrying flags 24:, adapted to be projected outwardly through the front ofthe casing, upon the rope or cord 16 becoming severed, as by a fire in the rooms through which the cord passes, thus calling the attention of passers by to the existence of a fire within the building, and constitutinga visible signal which can be seen from a considerable distance from the exterior of the building in any direction.

Arranged transversely and centrally in each of the several compartments or rooms 13 are other cords25, one end being secured to tension springs 26', set inthe upper por tion of the room, while the opposite ends of the cords 25 engage within, casings 26, se-

cured near the ceiling upon the opposite side of the room.

The inner endsof the cord 25 are directly engaged with levers 28, pivoted upon pins 29, mounted in brackets 30, the levers 28 beingheld normally upward against the pull of the cords 25 by springs 31, while theup-- per ends of the levers 28 are bevelled, as at 32, and adapted to make contact with bevelled projections 33 extending downward through slots 34: formed in the casings 3-5,

arranged contiguous to the casings 26.

The bevelled lugs 33 form one element of a bell-crank lever, the other element 36 being pivoted near its outer end to an arm 37,

formed with a bar 38, held in the casing 85,

which is provided with a cover 39, secured by the hinges 40 near the top of the casing in such manner that the same may be moved therefrom.

Engaged by a pivot a1 is a link 42, pivoted by the pins 43 to a bracket 44, arranged in the bottom of the casing 35, the bracket having a pair of upstanding lugs 46 and i7 respectively. Through the latter lug extends a plunger @8 having a sharpened conical point 49, and fixed upon theplunger is a collar 50, normally pressed torwarchdue to the spring 51,, abutting between the collar and lug 46, while extending from the plunger ll" is the b m 38, the same being provided with an operating handle 52, so as to present means whereby the lever and link 4L2 may be brought into alignment as indicated in Figure 3.

The joint pin 41, between the lever and link 42, is raised whenever the projection 33 is raised, which occurs by contact or the bevelled surface 32 of the'lever 28, thereby permitting the spring 51 toiorce the point 4L9 sharply forward and make contact with the head or a cartridge 54, held in a keeper 55, formed with the bracket 44:, the cartridge being maintained in position by the pin or bolt 56, the cartridge used being preferably a blank, which upon being detonated produces a loud sound calling attention to the confiagration existing within the compartment. Y

A projection 58 is formed on the lower end of. the lever28, and when the spring 31 is permitted to operate, it forces the projection sharply downward makii'ig contact with a plunger 60, which upon being depressed against the spring 31, moves the plate62 against contacts 63 and 64, the former passing into a casing 65, to thebinding post 66, while another binding post 67 conveys current derived from any external source of low voltage electrical energy through the wire 68, to one of the terminals 69, of an ordinary bell armature 70, thereby actuating a hammer 71 so as to make contact with the bell 7 2 causing the same to ring so long as the circuitis closed by the depressed plunger 60..

,The contact plate 62, when in a lowered position, also comes into engagement with the contacts 74: and 75, connected with the lead wires 7 6 and 77 so that the current entering through the connection 78 is distributed through the connections, thereby closing an auxiliary circuit directly connected with the fire compartment alarm system,

From the foregoing it will be seen that a visible alarm as indicated in Figure 2, is operated upon the inception ofa fire sufficient to consume the cords 16 in any part of the building, and coincidently with disruption of the cords25, in any of the several rooms, causesthe explosion of a car tridge, torpedo, or the like, creating a sound adapted to attract attention which is maintained by the continuous ringing or the bell "Z2 attractin' ithe attention of the passers by, while the fire department may be called. by having the wires 76 and .77 properly connected. H p v .,Tl1e, cor ds,25, entering thecasings 26, are also. engaged with levers 80 after passing over the pulleys 81, these levers being mounted upon pivots 82 and carrying their outerends pins 83 by which are connected links 84 adjustably engaged at 85, with arms 86, pivotally engaged at 87 withvfixed projections 92, secured within the cas Carried by the opposite ends o1 the levers 80 are blocks 95. supporting springs 96 adapted to actuate valves 105 controlling the passage within the pipes 97, these pipes being fed by inlets 98 from any convenient source of supply, as a tank upon the root, or service pipe of the building.

The outer end of the pipes 97 terminate in a downturned spray head 100 of the usual type, adapted to, dispense water from the pipe over a considerable radius when the valve is in an open positions A feeder pipe 101 is connected with the main pipe 97 at one end, has its lower, angular end 32 so disposed as to admit a small quantity of water into the container 88, causing it to tilt the arm 86 upon its fulcrum and normally raise the lever 80,1110- mentarily until thevalve 89 has become,

opened releasing the contents, whereupon the same effects are repeated.

From the foregoing it will be seen that an eiiective device for dispensing water in the form of spray into any of the several compartments has been disclosed, operative upon the burning of the transversely disposed cords 25 due to the effect of the fire within the compartmena and providing an effective and automatically operated means for controlling and quenching a fire in its incipient stage.

Having thus described my invention what I claim as new and desire to secure by Letters Patent,- is- V 1. In a fire controlling apparatus, the combination with a cord engaged at one end within the room of a building and a casing supported upon the outer walls of said building into which said cord enters, or a lever mounted in said casing at its lower end, connections between said lever and said cord. a spring adapted to force said lever outwardly, and a flag carried by said lever adapted to be normally disposedlwitl1- in said casing, said flag being liberated upon the disruption of said cord.

2.,In fire controlling apparatusg tlie combination with a hollowcaj'sing secured upon the, outer wall of building, a lever pivoted in the lower end or said hollow casing, means adapted to force the free-end or concealed position, and to the opposite side of a compartment within said building at its other end, said cord being subject to disruption by heat from a conflagration for causing the flag to be displayed.

3. In a fire controlling apparatus, the combination with a casing arranged upon one side of a room, a cord entering said casing, means for attaching said cord at the opposite side of said room, a lever pivotally mounted in said casing, a spring combined with said lever whereby said cord is held normally in a taut condition, a signalling means and means for releasing said signalling means upon the movement of said lever, said1 lever being freed by rupture of said cor 4c. In a fire controlling apparatus, the

combination with a casing attached to one ently attached to the opposite wall of the room, a release lever pivoted in said casing to which said cord is attached, means for tensioning said cord and normally moving said lever outwardly, a signalling means, a lever whereby said signalling means is normally held in a retracted position, and means for releasing said lever When said cord is disrupted.

In testimony whereof I have afiixed my signature.

EFREM MIHALOVICH.
