Description
dimitri tatw JOHN F. BOYNTON, OF SYAOUSE, NEW YORK.
Lette/rs Patent No. 96,876, dated November 16, 1869.
IMPROVED FIRE-EXTINGUISHER.
vThe Schedule referred to in these Letters Patent and making part of the same.
I, JOHN F. BOYNTON, of Syracuse, in the county of Onondaga, and State of New York, have invented certain lmprovemeutsin Fire-Extinguishers, of which the following` is a specification.
My invention relates vto that class of machines in which astri-am of' water, or water holding salts in solution, and highly -clntrged with carbonio-acid gas, is injectedupoii thej'fre'by the pressure 'of such gas,` generatedwithin such machine by the decomposition of suitable chemicals.
In the drawings- Figure l represents a sectional view of' my apparatus, and
Figure 2, an elevation of the same.
My apparatus consists of a closed vessel, A, provided Wth au opening in the top for the admission of water, ehemicals,'&c., and a tube, d, and stop-cock at the bottoni, through which the conte'ut'so'f the vessel may be discharged.
'lo the outside of the vessel A, near the top, is attached a generating-vessel, b, which communicates with the said -vessel A by means of' tubes, 'zc x', which may be provided with stop-cocks, if' desired.
This generating-chamber consists of a small vessel, of metal-or other suit-able material, and contains a capsule, `ofglass or other ma terial, which may be broken or pierced within it, by means of pressure from the Screw-rod c. In case a metal capsule is used, I make a small projection on the bottom of the generating" chamber, to pierce through the metal \vlieu press\1re is brought to bear upon the capsule by the screw- -To charge the apparatus, the vessel A is filled with a solution of sonic suitable carbonate, said solution entering the generating-chainber a through pipes xx. The capsule b is filled with acid and placed in the genmating-chamber w, after which the top is secured, and the apparatus is ready for use. On turning the screwrod c, its lower end is caused to press against, and break or pierce the capsule b, liberating the acid, which, xnixing\ with the carbonate-solution, decomposes it, and creates theirequired pressure in the generator and vessel A. Thesulphuric acid with which the capsule is` generally filled, being much heavier than the carbonate-solution, readily flows from the generator into the'vessel A, containing the carbonatesolution, through'the connecting-tube cv, while the water flows from the vessel A into-the generatingchamber through the tube x', thus producing a speedyand thorough mixture of the acid with the'ca'rbonated water.`
I claim, as my in'vention- The combination of' the vessel 'A with the generator e and capsule b, substantially as herein described.
JOHN F. BOYNTON..
