such as will enable others skilled in the art to i which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters or figures of reference marked thereon, which form a part of this specification.
My invention relates to portable fire-extinguishers; and it consists in the following. improvements, which will be fully understood from the following description, taken in connection with the annexed drawings, in which- Figure 1 is a diametrical section through my improved fire extinguisher, illustrating my improvements. Fig. 2 is a horizontal section through the device in the plane as illustrated by dotted line w m in Fig. 1. V
Referring to the annexed drawings by letters, Cdesignates the shell of the devioe,which is provided with a removable cover, 0, adapted to rest upon shoulders 0 integral with the said shell. This shell has a number of radial partitions, C, vertically disposed,which form separate acidulated-water receptacles, O, which will be hereinafter again referred to. These radial partitions terminate at a point, as more fully shownin Fig. 2, so as to allow a space for the cover or casing E to be placed in position against the edges of the said partitions. In the center of the said shell 0 is suitably suspended a cylinder, A, numerously perforated near its lower end and provided with a vertical partition, d, which extends to a hermeticallysealed cap or cover, 0. This cylinder is designed to receive any suitable alkali, which, when mixed with the acidulated water, will produce carbonic-acid gas. External to this cylinder A is another cylinder, B, having a funnel-shaped bottom, 0', at the base of which is an annular flange, G, adapted to afford a bearing for a removable casing, E, which,when it is in place, incloses the said cylinder B.
At the lower terminus of the funnel of the cylinder B is an extension, which tightly em- (No model.)
braces'the upper end of a vertical pipe, D,
which rests by its notched lower end upon the bottom of the shell 0, and is provided with two valveseats, upon which are adapted to u play vertically two puppet-valves, a 12. Both valves open upwardly and are provided with stop-collars on their lower ends, as shown in Fig. 1.
Surrounding the lower open endof the tube D is a cage, 0 to prevent sediment from clogging the lower end of said tube. This cage is preferably hemispherical, and is in commnni cation with the four acidulated-water receptacles O.
- Fromthe vertical pipe D radiates a pipe, 0", which communicates with a vertical cylinder, D, in which is applied a piston, a, and a piston-rod, the latter being provided with a packing at the upper end of the cylinder, and
also with a handle, as clearly shown in Fig. 1.
Now, in operation, the pumpcylinder D is put in motion and valve or opened by this upward stroke of the piston a. quantity of the acidulated water from the compartment G of the shell 0 into the pipes D O and the pump-cylinder D. The piston a is now pressed down,which operation forces the acidulated water through the trap-valvebinto the cylinder B, where it mixes with the alkali in cylinder A and rapidly produces carbonicacid gas. Now, again by depressing the plunger ta the carbonated water will be forced through the discharge-pipe c on the fire. The removable cover 0 allows free access to the in terior of the shell 0, and by removing the case 1 commingling of which produces carbonic-acid gas,which,when mixed and injected on a fire, will extinguish it.
Having described my invention, I claim- 1. In a fire-extinguisher, the combination, with the outer casing provided with a removable cover, of radial partitions terminating to afford a space for the insertion of the inner cover, E, subdividing the interior portion of this she1l,forming acid-receptacles,a centrally- This draws a IOL) arranged perforated alkali-receptacle, a cylinder, B, inelosing this reccptacle,provided at its lower end with npwardly-lifting valves, a suitable exhausting and forcing pump communicating with a pipe, D, between said valves, and an ejecting-pipe leading from the lower part of the said cylinder outward, substantially as described.
2. The combination, in a fire-extinguisher, ofa easing provided with a removable cover and radial partitions, an alkali-chamber perforated near its lower part and provided with a vertical partition, acyliuder external to said chamber provided with npwardlylifting trapvalves, a straincrbelow these valves, an ejecting-pipe above the valves, and a suction and forcing pump, substantially as described.
In testimony whereof I affix my signature in presence of two witnesses.
