CHEMICAL FIRE-EXTINGUISHER.

SPECIFICATION formingpart of Letters Patent No. 475,050, dated May 17, 1892. Application tiled December 10, 1888. Renewed October 12, 1891. Serial No. 408,417. (No model.)

To all whom it may concern,.-

Beit known that l, RUSSELL ARNOLD BAL- LOU, of Boston, in the county of Suffolk and State of Massachusetts, have inventedcertain new and useful Improvements in Chemical Fire-Extinguishers, of which the following is a specification.

This invention relates to chemical extinguishers composed of a casing having a disro cliarge-nozzle and one or more fragile vessels in said casing, said holders cont-aining d1fferent chemicals, which are mixed by the breakage of the vessels and by their mixture generate gases which escape forcibly through the f5 nozzle and carry with them the liquid with which the casing is supplied.

Extinguishers of this class are provided with means whereby the fragile vessels may be broken whenever desired; and my present zo invention has for its object to provide iinproved means for this purpose and improved means for holding the fragile vessels or bottles in place in the casing. n

To these ends my invention consists in the improvements which I will now proceed to describe and claim.

Of the accompanying drawings, forming a part of this specification, Figure 1 represents a vertical section of the casing and aside ele- 3o vation of the bottle holding and breaking devices. Fig. 2 represents a view of the same parts, taken from a ditfherentpoint. FigI 3 represents a section on line .fr Qc, Fig. 1. Fig. 4 represents a section on line y y, Fig. 1. Fig. 5 represents a perspective view of a portion of the apparatus. n

The same letters of reference indicate the saine parts in all the figures.

In the drawings, a represents the casing or 4o main receptacle, the same being provided with a removable cap or cover b, screwed to the body of the receptacle and provided with a discharge-nozzle c and wlth a valve (Z, from the casing of which a tube e extends down.

wai-diy nearly to the bottom of the casing. The plug portion d of the valve has a stem f, projecting above the cover and there provided with a handle f. When the said plug is turned to its open position, it permits the 5o passage of gas and liquid upwardly through the tube e and out through the nozzle, and

when said valve is turned to its closed position it shuts off the nozzle from the interior of the casing. To the lower end of the valveplug is affixed an arm g at right angles with the plug d', said arm being moved by the rotation of the plug.

The construction thus far described is the same as that shown in Letters Patent of the United States, No. 354,617, dated December 6o 21, 1886; but in that patent the arm g is shown as employed to retain a spring-impel'led bolt or bottle-'breaker when the valve Y is closed, said bolt being released by the arm g when the valve is opened and forced by a spring against the bottles t' t', which are supported by the tube e below the valve. l

In carrying out my present invention I secure to the outer end of they arm g a vertical rod le, the lower end of which is secured to a 7o similar arm g', connected by a pivot m to a lug n, affixed. to the vertical tube e. The rod lois thus adapted to be moved laterally by the rotation of the valve-plug d. To said rod are attached arms or blades o 0, which coincide with the bottles t' t', and are arranged so that when the rod lo is moved by the opening movement of the valve-plug they will bear against and break the bottles, thus liberating the contents thereof. This device constitutes a more posi- 8o` tive bottle-breaker than the spring-projected bolt above described, there being no possibility of failure to break both bottles at each opening of the valve. The bottles are supported by ring-shaped holders r r, rigidly attached to the tube e and embracing the contracted lower ends of the bottles, and by vcrticallyadjustable ring-shaped holders s s, which embrace the contracted upper ends of the bottles and are attached to slidest t, which 9o are vertically movable in guides or sockets u u, attached to the tube e. The slides tt are preferably flexible strips of metal bent into U form, the ends of the strips being attached to the holders s s. This construction enables the sides of the strips to bear with a yielding pressure against the sides of the sockets u u, and thereby sustain the holders s s by friction at any height to which they may be adjusted, so that if the holders s s are roo raised above the position they occupy when holding the bottles to permit the insertion of Y ing devices, ot' the arm g on the plug of said the bottles they will remain in said position while the bottles are being inserted and can afterward be pushed down to hold the bottles, as shown. The rod 7c maybreak the bottles by direct contactwith the same, in which case the blades or projections o may be dispensed with. v l

Instead of attaching the lower end of the rod. la to an .arm g', made as a separate piece, the said lower end may be bent linwardly, as indicated by the oblique dotted lines in Fig. 1.

1. The combination, with the casing or receptacle having the valve d, discharge-nozzle c, discharge-.tube e, and suitable bottle-hold,

Valve, the bottle-breaking rod k, securedV to said arm'and having a pivotal connection at its lower end with a Xed, support, as set forth.

2.` The combination, withthe casin gs, ofv the holdersf, rigidlysecured Awith-in the' casing,

the socketsu, affixed abovesaid holders to a rigidsupport, and the holdersfsg havingV the sition, as set forth.

spring pieces or slides t, adapted to enter said sockets and by their frictional Contact therewith to hold said holders s at any desired po- 3. The combination of the casing, the tube or support e within the saine, provided with sockets u, the holders r, affixed to said support, the holders s, having the. spring pieces or slides-t, adapted to enter said sockets and `by their frictional contact therewith to hold said holders s at any desired position, and a Y suitable device operated from the outside of the easing, adapted to break bottles or other fragile vessels supported by said holders s and o", as setforth.

In testimony whereof I have signed my naine to this specification, in the presence of two subscribing witnesses, this 5th day of October, A. D. 1888. A- l -RUSSELL ARNOLD BALLOU.` f Witnesses:
