EMIL EHLER, OF IIENRICO COUNTY, VIRGINIA.
FIRE-ALARM.
SPECIFICATION forming part of Letters Patent No. 593,536, dated November 9, 1897.
Application filed March 13, 1897.
1'0 all whom it may concern.-
Be it known that I, EMIL EHLER, a citizen of the United States, residing in Henrico county, State of Virginia, have invented a certain new and useful Fire-Alarm, designed to give notice when a fire occurs, of which the following is a full description, reference being had to the accompanying drawings, in
which like parts are represented by like letters.
My invention consists of a fusible cord running through a house. in and through aspecially-devised metal pipe, as hereinafter described, and out through the wall to the outside of the house, where the fusible cord is connected with torpedoes or cartridges made of powder or dynamite, which are to be exploded in case of a fire, and thus give an alarm. The metal pipe is formed by connectin g together small sections of screw-threaded pipe by means of screw-threaded T-couplings, the openings in the latter being used to insert small pieces of fusible cord and connect the same with the main fusible cord, and thus form a transit for the fire to the main fusible cord.
In the accompanying drawings, Figure l is a perspective view of the interior of a house or dwelling, showing one form of the application of my fusible cord with its protective casing thereto. Fig. 2 is a perspective View of the exterior of a house or other building, showing the protective casing with its fusible cord passing through one side thereof and the torpedoes connected thereto. Fig. 3 is a perspective view of a detail of my device, showing the torpedo incased in its protective covering; and Fig. & is a perspective view of another detail, showing the arrangement of the screw-threaded pipes connected by means of T-couplings, the main fuse passing through the pipe and connections from the main fuse exposed through apertures in the T-couplin gs.
To the ceiling or other suitable support F of the interior of a building I secure suitable depending brackets H, adapted to support sections of screw-threaded pipes A, joined together by means of screw-threaded T-couplings 13, provided with apertures K. The main pipe passes from the interior of the building through a suitable opening in the wall to the outside of the same, as shown in Serial No. 627,289. (No model.)
Fig. 2, where the sections are joined by apertured T-couplings similar to those used in the interior of the building. Through the main pipe A passes the fusible cord E, which extends throughout the length of the same, and to which are attached cartridges or bombs D by means of branch fuses A of different lengths, connecting the same through the apertures in the T-couplings to the main fuse E.
Through the apertures in the T-couplings shown in the interior of the building are exposed short fuses O, communicating therethrough with the mainfuse E, and intended in case of fire to ignite and transmit the fire to the main fuse, which will burn along the interior of the pipe until it reaches the bomb, which then explodes and thereby gives the alarm.
I11 case several bombs are used the alarm will be sounded at periods of different intervals.
The pipes A are provided for the purpose of affording a protective covering for the fuse and thereby prevent its falling and communicating the fire to the other parts of the building. The apertures in the T-couplings also act as vents, through which sufficient oxygen will be supplied to the burning fuse to insure its combustion and the fire reaching the torpedo.
Suitable cases, of rubber or other material, are provided for the bombs or cartridges, and the fuses are provided with pipe-coverings A to protect them from the effects of the elements.
The device may be carried through several rooms or several stories before being carried through the wall to the outside of the house. In stores, warehouses, or other large buildings it is better to have two or more on each floor, according to the width of the room, and to carry them directly out through the wall to the outsideof the house.
Having described my invention, I claim as new 1. In a fire-alarm, the combination of afusible cord running through a house, by means of and through a metal pipe formed as described by connecting sections of screwthreaded pipes together with screw-threaded T-couplings, the fusible cord being'connected with a torpedo or cartridge made of powder or dynamite, and placed on the outside of the cord passing through the pipe its entire length, a bomb or cartridge attached to the I 5,
fusible cord on the outside of the building, short fuses connected with the main fuse and exposed to the flames through the apertures in the pipe, all substantially as described, 'and intended and adapted to sound an alarm by the explosion of the bomb.
In witness that I claim the foregoing as my own I have hereto affixed my signature in the presence of two Witnesses.
EHIL EHLER.
