CLASS 61: Rescue Services.

A device is to be provided in the mobile fire extinguisher described below which ease of use and removal are combined in and with the help of chemicals to contain dangerous fires and extinguish them as quickly as possible should aim. . '

The drawing shows in Fig. 1 side view of the complete car, Fig. 2 the hydrometer, Fig. 3 view of the pipe feed respectively. Pipe discharge, FIG. 4 shows a view of the rear of the two boilers AA ¹ and FIG. 5 shows a cross section through the boiler.

On the front half of the wagon consisting of the wagon frame D with the wheels FF ¹ F ² F ⁸ (Fig. 1) are on an iron frame E, on springs / resting, two boilers AA ¹ . The branched supply pipe c opens into this, on which latter the main shut-off valve b and the valves e and e ¹ serving to shut off each individual branch are located. Before the division of the pipe c , the supply pipe m branches off to the upper boiler B ; the same pipe system is at the other end of the boiler for draining BEZW. Allowing the boiler contents to flow out is attached, ν and v ^l correspond to e and e ¹ , b to the tap w. There is a screw connection α on the inlet pipe c for coupling with the hydrant hose d. Furthermore, there is a manometer n on each boiler, an air cock g to let the air in the boiler escape, two drain taps 0 and p, 0 connected to each other by pipe q for setting the water to a certain level, ρ for completely emptying the boiler. A hydrometer w, Fig. 2, rotatable in all directions by means of a ball joint, is arranged on the rear wall. When using the same, the liquid is passed into the glass vessel by opening the tap t and, after checking the salt content, emptied by opening the tap α through pipe y. The front wall is verschliefsbar by a 45 ⁰ rotatable lid. A third, smaller one, B, is placed above the two kettles.

It is connected to the supply pipe c on the one hand by a pipe m that can be shut off by means of a tap, and on the other hand by pipe r, which can be shut off by tap s, to the outlet pipe x. The chemical liquid is pumped in through opening Z, the air contained in the boiler can escape through tap k; a water level indicator h marks the current level of the boiler content.

The rear half of the car forms a frame made of iron rails, made according to the purpose, which is used to hold the four cartridges CC ¹ C ² C ⁵ containing the fire extinguishing agent.

The cartridges themselves are by means of rollers towards β - and herschiebbar and by a second Holy, hinged rotatable to the lateral surfaces of the cartridge lid closed folgendermafsen:

The two cover surfaces are at the edges where they coincide with a sleeve which is cut out so that the remaining part of the one lid falls into the cutouts of the other half and

is now prevented from falling apart by a pushed through rod ε; a grip on the relevant rod requires more comfortable handling. These are the chief parts shown in the drawing; If the device is to be used, proceed as follows: The kettles are filled with water up to the tap ο , then the air tap g is opened, as is the lid i ; by the latter handling the space between the frame E ¹ and the boiler is bridged and the cartridge is pushed on the path thus formed into the boiler, in which the path continues, opened by removing the rod and, after emptying, pulled out again and passed through brought a corresponding device into the punctured position; the previously occupied space is now taken up by a new filled cartridge. Then cover i is closed, main tap b and tap e are opened, and the water flows in. After filling is complete, air cock g is closed. Then tap w and ν are opened, and the liquid, which is now mixed with the chemical salt, comes out of the boiler through pipe χ; the device is thus in operation until the salts are completely washed off, and the same procedure is used with the second kettle during this time. By hydrometer u Rann the mixing liquid are observed with respect to their tightness libitum. When boiler A is exhausted, tap e ¹ and v ^{1 are} opened, tap e is closed, and boiler A is thereby in function. The excess water is then drained from boiler Ά by opening the tap ο and the device is back in its former state. An agitator (Fig. 5) is also installed in both tanks. Two rods connected with gears & are simultaneously moved in opposite directions by a corresponding switching mechanism and carry fan-like brushes γ, which move against each other when rotated and take between them and crush the salt that may form lumps. It is assumed that the two. Boilers A and A, as well as B, properly filled and ready for use, come to the place of the fire, and that there are four intact cartridges on carriage part E ^1. Boilers A and A ¹ are intended for 250 l, boiler B for 100 l, and the cartridges for 100 kg of salt. Patent claim: Mobile fire extinguishing device for the use of extinguishing salts, in which the lid i of two boilers A and A ^1, when opened, form a bridge with a frame E ¹ carrying the fire extinguishing cartridges, so that the cartridges are inserted into the boiler on a straight path, then pulled out again after they have been emptied will. 1 sheet of drawings.
