PROCESS OF AND APPARATUS FOR GENERATING DIOXIDE OF CARBON FOR EXTINGUlSHlNG FIRE.
SPECIFICATION forming part of Letters Patent No. 263,015, dated August 22, 1882.
I Application filed September 20, 1881. (No model.)
To all whom ct may concern:
Be it known that I, JOHN F. BoYNToN, ot' the city, county, and State of New York, have invented certain new and useful Improvements in Apparatus for and Processes of Generating and Utilizing Carbonic Acid and otherGases, of which the following is a specification.
My invention relates chiefly to the production of dioxideiof carbon by a novel process and apparatus therefor, the object of the improvement being to form the gas atlow pressure in a closed vessel and in large but continuous volume, and to arrest the chemical action at the will of the operator for extinguishing fires.
Several distinct inventions for extinguishing fires by carbonic-acid gas combined with the spray or vapor of water are in well-known holder without breaking it; and still others require that the entire apparatus be turned upside down to allow the acid freedom to mix with the salt or'its water-solution, and so on.
All these contrivances involve three objectionable and uncontrollable features: first, that when once put in use the generating of the gas must go on continuously until-the chemical action is exhausted, whether needed or not;- and, second, the consequent extreme and often dangerous pressure exerted thereupon; and, third, that the sulphate of soda is formed as a hydrated crystallized compact salt adhering to the sides and bottom of the cylinder, requiring disagreeable labor and time for its removal in fitting the vessel for another charge. Most of the metallic generators referred to are made portable, to be carried on the back or otherwise. Others are made larger and placed on wheels, and even on carriages to be drawn by horses, in all of which 'cases the objections named apply with augmenting force as the volume of the generator is increased.
My improvements consist in the construction and novel use of a cylindrical vessel of metal, placed on its side upon and against friction-rollers in proper bearings, so that the cylinder may be rotated circumferentially, and having on its inner surface longitudinal or spiral flanges, continuous or in section, secured to and projecting from the sides. I mount one or more such cylinders in proper framewith sheet-lead or other proper material to resist the acid. The cylinder or generator thus placed on its side is capable of being rotated vwhile in action by a hand-crank, as shown in the drawings. 1 And my improvement further consists in a novel treatment of the elements from which I produce dioxide of carbon at low pressure for extinguishing tires within a vessel the interior of which is always in open communicat-ion with the exterior air. As the generating-vessel used in my process acts by the revolving method, so long as it is in action the gas is freely developed, and when the fireman stopsthe rotation and the acid-supply is cut off the generation of gas is arrested but whether thevessel be in operation or not, it is always intended'to be open to the external air through the nozzle and exit-pipe, whereby the pressure within the generator will be that, derived from the m's a tergo resulting from the chemical decomposition, setting free the said gas. (See drawings, Fig. 1.).
Figure 1 shows a plan of a single cylinder, a, with its attachments; and Fig.2 represents an end elevation of three cylinders combined on a truck-frame, I), designed to be placed on wheels for transportation by horses.
0 c are bearers, of caoutchouc or other proper yielding material, secured to supporting-blocks fixed to the frame I), and on which the cylinders.
rest and are transported when not in use.
d d are friction-rollers secured in the framework of the apparatus at the sides of the ends of the cylinders to steady them in position and facilitate their rotation.
V e e are actuating friction-rollers under the centers of each end of the cylinders, and rotating on journals in blocks that slide vertically in the frame b, or otherwise, by an elevating and depressing lever or screw, 6 e, by which the cylinder may be raised clear from the bearers 0, so that it will be supported on the pulleys or rollers 6, having strong journals, their outer ends made to project beyond their bearings to receive a hand-crank, h, fixed in position only when the cylinder is to be rotated, which is efiected byfriction between the bearing-surfaces ofithepulley and the edges of the cylinder end s fvvhi clisurfaces may, if necessary, be provided with interlocking gear or other device to insure rotation; and, instead of the cylinder being raised by the actuating-pulley e away from the support 0, those supports may be loweredby any convenient device, so as to allowthe cylinder to bear upon the pulleys, asfirst' stated;
g 9 represent man-hole plates, alike in each end of the cylinders, the centers of which plates are perforated to take a union gas-joint and short screw-capped pipe, 8, to'receivea gaseouducting hose, Lat one end and the acid-charging tube 70 at the other end, as shown at Fig. 1.
o shows a man-hole plate on theside of the cylinder, which :has another capped orifice on the opposite side, (not shown in Fig. l
The carbonate salts placed inproper-sized charges are stored in a magazine-box on the carriage, and the sulphuric acid, of notless than G6 Baurn specific gravity, as containing least Water of constitution, is stored in leaden or other proper flasks placed in a second magazine-case, also on the carriage.
To operate'the machine one or more of the charges of the carbonate salts taken from the magazine areplaced in the cylinder by one or more of the man-holes, and a flask, m, of acid,
laid upon a proper place of restupon the machine, has its conductiugtube In of rubber attached, the opposite end of which is united to the cylinder by the short pipe 8 or otherwise,
a short bend in this tube being collapsed as a sealing-valve at 1, held by any convenient clampingidevice. The cylinder is now raised away from the support 0 by the hand-wheel e and the crank 12. adjusted in position.
The acid may be released by removing the clamp at r and turning the crank h. The friction at 0 will cause the cylinder to rotate by a slight force only, mixing the acid and carbonate, the generatedgas flowing freely by the hose and nozzle 'i as dioxide of carbon free from presence of or admixture with Water, except that portion which may have been held in the acid, and formed in a vessel with its outlet at all times open to the atmosphere, and in the absence of internal pressure other than that produced by the generation of said gas.
In practice it is designed that the rotation be alternately from right to left by single or half turns only. Cessation of the crank motion or closing of the acd-tube should arrest erators are used they should be worked alternately, shutting off one while employing the other.
To clear the cylinder from spent salts, remove the man-hole plate at o andinvert the cylinder. The residuum will flow out and a slight stream of water by anotherman-hole will quickly Wash clean the interior.
By the described process I am enabled to generate dry dioxide ofcarbon, one cubicfoot of which is suffioient to render about ten cubic feet of atmospheric air capable of extinguishing flame.
The described apparatus is designed for use without internal pressure other than that due to the weight of the column of gas in the conducting-hose; but, as a precaution against undue pressure from accidental closing of the outlets or otherwise, I attach to each cylinder a safety-valve and pressure-gage.
It will further be seen that my rotating cylinder as arranged and operated is also adaptable for use in generating dioxide-of-carbon gas under pressure with water as wellas without.
What I claim, and desire to secure by Letters Patent, is
1. In an apparatus for generating dioxide of carbon for extinguishing fires, the cylinder a, mounted upon proper frame-work and arranged to be rotated circumferentially, in the manner substantially as set forth.
2. The described mode of extinguishing fires in buildings or other places by the use of ordinarily dry dioxide of carbon, which consists in liberating said gas by the action of a suitable acid and carbonate salt, without the intervention of water or other liquid medium, said gas being liberated under ordinary atmospheric pressure and placed under such conditions of elevation of apparatus to the height required as to deliver said gas upon a fire in buildings or other places.
