UNITED STATES PATENT OFFICE.
WILLIAM MILLER, OF GLASGOlV, SCOTLAND.
FIRE-EXTINGUISHER.
SPECIFICATION forming part of Letters Patent No. 395,069, dated December 25, 1888.
Application filed October 25, 1887. Serial No. 253,286. (No model.)
To aZZ whom it may concern.-
Be it known that I, \VILLIAM MILLER, a resident of Glasgow, Scotland, and a subject of the Queen of Great Britain and Ireland, have invented a new and useful Improvement in Fire-Extinguishers, of which the fol lowing is a specification.
My invention relates to fire-extinguishing apparatus of the kind in which a carbonate or bicarbonate dissolved in or contained with water is confined in a vessel along with an acid, which acid is kept separate until the apparatus has to be used, but is then made to mix with the carbonate or bicarbonate and water and causes the evolution of carbonicacid gas, resulting in the forcible expulsion of the solution and gas through a pipe and nozzle provided for the purpose of directing the jet on the fire.
My object is to construct such apparatus in an improved manner, in an extremely portable and convenient form, and so as not to be liable to premature action of the acid, while capable of being set in action with great facility when required.
lfill'G-QXtlll guishin g apparatus made according to my invention is shown in the accompanying explanatory drawings, Figure 1 being a longitudinal section, and Fig. 2 a transverse section. Figs. 3 and i are longitudinal and transverse sections, showing modifications of some parts of the apparatus.
The vessel A of my improved apparatus is a long tube-l ike cylinder of a size which can be conveniently gr sped in the hand, and which may be made of tinned iron or steel or other suitable thin metal. (overs B C are soldered or otherwise fixed on the ends, and to what may be regarded as the upper end, l3, there is fixed a wire loop, I), by which the apparatus can be hung upon a nail in a convenient position for being taken hold of when required for use. Through the same end, B, there projects the nozzle E of a pipe, 11, which extends inside nearly to the other end,awiregauze strainmr, G, being fixed on the other end to preventthe pipe from being choked. The nozzle E is closed by a tightly-fittingrubber cap, H, which is withdrawn when the apparatus is about to be used.
The sulphuric or other acid is contained in a small glass bulb, J, which is hermetically closed, and is placed within a small cylinder, K, fixed to a bridge-piece, L, fixed across the vessel A, andliaving a hole made through its middle. The acid-bulb J is introduced through the end cover, 0, which is made with an internally-screwed neck provided with a screwclosing plug, M, the carbonate or bicarbonate and water being introduced through the same opening before the acid-bulb J is put in. To the inner side of the plug there is fixed a short tube, N, having inside of it a loose bolt, P, of cast-iron or other heavy substance.
My improved apparatus is set in action by simple concussion transmitted through the shell of the vessel, there being no rod working through a packed or unpacked orifice, leakage through which can hardly be prevented. When required, the vessel A is simply grasped in the hand and its end M is struck smartly against a tloor or any firm hard substance. The concussion of the blow, acting through the loose bolt P, causes the breakage ot the acid-bulb J, and the acid in it immediately acts on the carbonate or bicarbonate and produces the desired result.
It is not essential. to have a loose bolt, l as simple concussion is quite su'lficient.
In the modification shown in. Figs. 3 and ii, the end O is closed by a plain cap, Q, instead of a screw-plug, M, this cap Q being soldered in its place when the vessel has been charged. A tube, N, of thin metal is fixed to the inside of the cap Q, and the acid-bulb .I is in contact with the inner end of it. \Vhen required, the breaking of theacid-bulb J is easily effected by smartly striking the end cap, Q, once or oi'tener, against the floor or any firm hard substance.
\Vhen the screw-plug M is used the hanging loop I) may be fixed at the same end of the "essel, so that the plu may be uppermost when the apparatus is hun up; and it may be mentioned that when the loose bolt P is used a blow with or on either end of the vesselis equallyelt'ective in breaking the acid-bulb J.
