EUGEN WIDER, OF STUTTGART, VVRTEMERG, GERMANY.
AUTOMATIC r-lRla-ALARn/l.`
SPECIFICATION forming part of Letters Patent 110.419,902, dated January 21, 1890.
Application filed July 10, 1889.
To all whom it may concern:
Be it known that I, EUGEN WIDER, of Stuttgart, in the Kingdom of Vrtemberg and German Empire, have 4invented new and useful Improvements in Automatic Fire-Alarms, of which the following is a specification, reference being had therein to the accompanying drawings.
This invention relates to an automatic firealarm for dwellings, warehouses, factories, barns, &c. and it consists of an apparatus placed in such premises and operated at the outbreak of a fire, by means of one or more fuses, so as to eiect a'strong detonation and to operate, by the closing of an electric circuit, one or more electric gongs or bells in suitable localities.
Figure 1 is a plan of the apparatus, showing several parts in section on the line ab, Fig. 2. Fig. 2 is a side view showing the apparatusin section on the line H H, Fig. 1.
This fire-alarm apparatus is constructed, essentially, as follows: l
A is a metallic plate about ten centimeters long and eight centimeters wide, which is screwed to the wall, floor, or ceiling of the room at any convenient part. On this plate A is fixed a metallic chamber B, closed at one end by means of a tightly-fittin g cork plug el, with a pin or screw, to which is attached a metal plate e. The other end of this chamber has an opening for the reception of the fuses c c, which are connected to a detonating-cartridge within the chamber B. Opposite to the plugged end of the chamber B is placed a block l Z, through which movesa pin g,having the head f. This pin g slides in a suitable guide h, and its free end is opposite to one end of a contact-spring t, the other end of such spring being fixed to the block and connected by means of the wire oc with the electrical signaling apparatus. The other wire is connected to the finger k, which is likewise fastened at one end to the block.
The fuses c c, which are well prepared with saltpeter and phosphorus, are laid along the Serial No. 317,059. (No model.)
walls or in other suitable places in the dierent rooms, and their ends are placed, preferablynear the Iioor.
The action of the apparatus is as follows: At the outbreak of lire in a room or building supplied with fuses the iire cannot spread beyond the fuses without being noticed. If one of the fuses has caught fire, the latter will be transmitted in a few seconds to the metal chamber B, where it explodes the detonatingcartridge contained therein. According to the composition of the cartridge the detonation will be more 0r less loud, and will attract the attention of persons near it. At the same time the cork plug d is blown out of the chamber against the head f of the pin g, which thus pushes the spring c' into contact with the iinger k, closing the circuit and operating the gongs orbells or other annunciator, which continues until the circuit is again broken.
The signaling apparatus may be at the firestation or at any other convenient point.
It is desirable to adopt fuses and cartridges Which are not. readily aiected by moisture or change ot temperature to an objectionable degree.
lVliat I claim, and desire to secure by Letters Patent of the United States, isN
In an automatic fire-alarm apparatus, the combination of the annunciator in circuit, a spring-actuated circuit-closer z', a block Z, carrying the circuitcloser, a pin in line with and operating the circuit-closer and supported in the block, a detonatingcartridge carrying fuses at one end, and a plug at the other end of the cartridge and capable of being expelled with force by the explosion of the cartridge against the pin to operate the circuit-closer, substantially as described.
In witness whereof I have hereunto set my hand in presence of two witnesses.
EUGEN WIDER.
