PATENT OFFICE.
N. Y., AssIGNoE To ErMsELE AND FRANK FARWELL, OF SAME PLACE.
IMPROVEMENT IN FIRE-.EXTINGUISHERS- Specification forming part of Letters Patent No. 154,539, dated September 1, 1874,; application liled July 10,1814.
To all l,whom -itrmafy concern:
Bc it known that I, ABNER H. ANGELL, of Y the city of New York, county and State of New York, have invented a new and useful Improvement in Acid-Bottles for Fire-Extinguishers, reference being had to the accompanying dr( wings forming part of this specigas is generatedvby the action of an acid upon a carbonate, and in which the acid is liberated for action upon the carbonate by breaking the bott-le containing it; and consists in a bottle having a tapering recess made in its base, into which is fitted a correspondingshaped plug or wedge,ywhereby, by forcing the bottle upon thel plu g, the walls of the base are spread asunder and the bottle broken.
Fig. 2 represents a glass bottle ot ordinary general construction. ln the base of this bottie. is formed a tapering recess, A, extending, preferably, entirely across the bottle. This is done in the manufacture, by pressing the glass while hot into the desired shape, or by a properly-formed mold. Fig, l shows a View of the bottle and Wedge turned a quarter round from the position seen in Fig. 2. B is the frustum of a wedge, made, prefer( bly, of metal. 'lhe inclination of its sides should correspond to that of the sides of the recess. The base is wider than the base of the recess Aand there is some space between the top ofthe frustum and the upper surfaceor angle of the recess. rlhis bottle being set down upon this Wedge-shaped plug, the latter f1tting into the recess, it is evident that, by the pressure upon the top of the bottle, the Wedge will be driven into the recess, thereby spreading the Walls of the recess asunder and breaking the bottle.
The wedge may, for convenience of holding the bottle in place upon it when in the extinguisher, have standards or arms C D secured to its ends, the bottle being placed between them. These standards extend upward and are secured to the apparatus usually employed to apply the pressure to the top ot' the bottle,
lWhich is ordinarily a screw-rod extending` through the top of the extinguisher.
I do not limit myself to the precise form of the recess and plug here shown and described. Itis only essential that they shall be so formed,
relatively, that, pressing the bottle down upon the plug, the latter will act as awedge to spread asunder the base of the bottle, and thereby break it. Y
The combination of a bottle having a tapering recess in its base with a tapering plug placed in the said recess, substantially as and for the purpose specified.
Witness my hand this 7 th day of July, 1874.
