where the supporting` structure is in the torni ot" a ha' as here shown. the edges of the dish are notched to receive the side portioua oi the ha r, and the laag may he eecured to the disk or washer of cardboard by appllviueo'luc to the disk betore it is placed in position. By the use oi one or more of these washers the container may he properly positioned with relation to the other parteI to cornprluaite for any variations in the size@` of the diti'creut containers, or to elevate the container to the proper point with relation to the breaking device.

llnder uoruial eontlitione the pressure ap plied to the container, as above described will couipk-teliY shatter the saine, 'but should. there be ineuilicient liquid within the container, or should it lor any other reason tail to hlealr under the pressure, it ie desirable that other nreane Should he provided for breaking the saine. This we have accomplie-lied hy forming the disk l0 ot l, and 15 ot' il? 3, of a Width greater than the adjacent portions oit the respective containers. Thus if the Stopper is forced into the container for its lull length Without hrealo iugthe same. the laterally projectingw pote tions; of the elisir will come in' contact with the edge ot the container and crush it. .lin this manner the breaking of the vial, or oontainer, ie rendered absolutely certain.

ln order that it may he determined from outward appearance Whether or not the eX- tingri 'eher is charged andreadv for service, we have provided means for locking the plunger against returning' to its normal position after it has been operated, thus holding` the knob, or 'button il clos-e to the Cylinder head and indicating` that the device has been operated. This may be accomplished in various Ways, but in the present instance, we have secured to the Cylinder head above the disk l0 two depending.,v resilient lingers, 2G, which when unrestrained will diverge downwardly as shown by the dotted lines on Figu l, hut theyv may he moved inwardly and caused to enter openings in the dish; l0 aud stopper Z when the latter are in their normal positions. 1When the plunger has been moved inwardly far enough to break the container the disk will he moved liar enough to release the resilient fingers which will spring out of alineinent with the openings in the (liek, hut will lio in the path of the edge portions; thereof, thus etteetively ,preventing the upward movement of the plunger. inasmuch ai; these fingers are inaccessible from the exterior of the casing it is oliviou; that the plunger cannot he returned to ite normal position Without removing the cylinder head. The lingers 2G also serve to lock the disk and the Stopper aggainet rotation.y thus preventie(e,- the die placement o1' breaking; ot the vial in the handlin-g o1 the extinguisher.,

To facilitate the .placing of the disk in poeition, We 'have threaded the discharge opening; throughout its length, and have mounted therein a threaded plug 29 having an opening ot the same size as the openingv rEllie paper closure ieA ap-Y plied to theinner end of this plug to close the openingrtherein, and the plug' is th-eu Screwed into the discharge opening, aiiter which the nozzle ie placed into position.
