Description

It is well known that all fire extinguishers equipped with fittings, into which the blows that are STRICTLY protruding outward, surrounded by glands, go are unsatisfactory in that the glands dry out during storage, allow crystallization of the solution inside the apparatus, than from freehand movement. the impactor, cause it to bend or break upon impact and stop the apparatus, in view of which a fire extinguisher is proposed, in which the impactor, being accurately ground to the retaining head, is hermetically pressed thereto in the idle state by the coil spring, and by the action of the apparatus and also an internal pressure developed in the machine.

In the schematic drawing of FIG. 1 shows a diametrical section through the head of a fire extinguisher in an inoperative state; FIG. 2 shows the head from above and FIG. 3 - axial section of the fire extinguisher when struck by the HEAD at the beginning of the action.

The armature of the fire extinguisher consists of the HEAD 4, screwed onto the neck of the vessel of the fire extinguisher (Fig. 1-3) and fitted with a hollow outwardly protruding cylinder 5, opened laterally and fitted in the bottom with a central opening 6 for passage

hammer rod 7. A spiral spring 8 is attached to the hammer rod, which is fastened with a button 9 screwed onto the hammer end, equipped with a conical rim 13 held by RING 10 and screwed into the canal of the ARMON 4. The ring 10 has a slope 14 accurately ground on the edge of the rim 13. Other the end of the hammer is equipped with a button 12, TIGHTLY fitted to the underside of the cylinder 5 of the head. In the off state (FIG. 1), the coil spring 8 TIGHTLY presses the rim 13 of the head against the slope 14 and the button 12 in the cylinder, 5, thereby sealing the fire extinguisher. To bring the fire extinguisher into action, it is hit with button 9 (Fig. 3), then the bottom button 12 of the rod breaks the vessel with acid 15 and the gases developing inside the vessel, as well as the spiral spring 8 tightly presses: buttons 9 and 12 to their places, and the foam forming inside the vessel is ejected through the side opening 16.

Subject patent a.

Chemical fire extinguisher, distinguished by the purpose of warning: the possibility of bending or breaking the rod,. n 7 drummer (Fig. 1 and 2) when the fire extinguisher is activated, the said rod is placed entirely inside the head 4 of the fire extinguisher and its button 9 is pressed out by the coil spring 8,

 2 i is provided with a conical rim to rest against the corresponding slope of the ring 10, and instead of the missing gland, the lower button 12 of the striker fits tightly to the underside of the cylinder 5 of the head 4,
