ACID-BOTTLE GAGE FOR FIRE-ExTlNG-m uns.

Specification of Letters Patent. Patented March 31, 1908.

Application filed April 30, 1906. Serial No. 314,534.

To all whom it may-concern:

Be it 'known'that I, JosEPH M. MILLER, a

the acid bottle.

, Chemical fire extinguishers of the class to which this invention relates, usually consist of a casing or tank having an opening at its upper end and containing a liquid suitable for fire extinguishing purposes. A bottle containing an acid or chemical is supported in a fixed position in the upper part of the casing with its mouth spaced away from the cap which closes the casing, the mouth of the bottle being usually closed by a loose cap. The liquid in the casing also contains an agent which, when mixed with the chemical in the bottle, causes a rapid formation of gas, the pressure of which is used for discharging the liquid from the casing. The mixing of these chemicals is usually accomplished by inverting the casing and permitting the chemical in the bottle to How out.

The main objects of this invention are to provide a simple and improved form of cage for supporting the acid bottle in fire extinguishers of this class, and to provide a construction for such cages which will permit I the bottle to be readily inserted or with drawn from the cage, to be supported in a fixed position within the casing, to be readily removed from or inserted in the cage without withdrawing the cage from the casing, and to provide a resilient form of clip capable of holding a bottle in a partly lifted position in the cage for convenience in filling the same. I accomplish these objects by the device shown in the accompanying drawings, in which:

Figure l is a side elevation, partly broken away, of an acid bottle cage constructed y according to this invention, the casing of the partly broken away.

fire extinguisher being shown in section and Fig. 2 is a side elevation of the cage showing the bottle supported in a partly lifted position. Fig. 3 is a perspective viewof the cagewith the bottle re,

moved.

In the construction shownin the drawings, the casing 1 of the fire extinguisher is provided at its upper end with an openin or throat-2' having a threaded neck 3. he cap of the fire extin uisher, which closes .the opening 2 is of well own constructionend is not shown in the drawin s. The ihterihr.

of the neck 3 is provided with a pluralityof lugs 4 which form shoulders for supporting the bottle holder or cage. The cage -con-' sists of a ring 5 which is of suitablesize to fit within the neck and rest upon the lugs 4. A bottom 6, is secured in parallel relation with the ring 5 and is ri idly connected therewith by a pair of uprig t side supports.

7 which are fastened to the bottoni at opgosite ends of one of the arms thereof. spring clips 8 formed of resilient wife are rigidly fastened to the opposite ends of the otherarm of the bottom 6 and extend upwardly so as to provide a ca e for confining an acid bottle 9 bet-ween said vertical wires when seated upon the bottom 6. The clips 8 are bent inward at 10 near their upper ends so as to extend over the shoulder 11 of the bottle and support the samewhen the casing is inverted.

The clips 8 are bent outwardly above the bends -10 so that they will spring outward to permit the bottle to be inserted into position.

The usual loose cap 12 is provided for closing the neck of the bottle and has the shank 13 which extends into said neck to prevent the cap from falling out oi -place when the extinw guisher is inverted or turned on its side. l

The operation of the device shown is as follows: The bottle is inserted into the ca e by passing the same downward through t e ring 5 and pushing it down .until the clips 8' engage its shoulder and hold it firmly H1 positlon. The yielding structure of the clips 8 causes the same to hear u on the bottle to prevent its rattling, and a so to accommodate themselves to variations in the. size of the bottles. iVhen the casing 1 is inverted after its outer cap has been screwed into place, the bottle is supported by the clips 8 so that the cap ll? of the bottle will fall away from the mouth sufliciently to permit the fluid contents of the bottle to run out and mix with those of the casing.

For convenience in filling the bottle, -it may be artly lifted from the cage and will be held 3 the clips 8, inasuch osition, as shown in Fig. 2. '1 his permits it to be filled without entirely removing it from the cage. A further advantage of this partly lifted structure is that the bottle may be removed or held in a partly lifted position or replaced. into the cage without the removal of the cage from the casing. This feature .is of great "advantage to the persons who refill the bottle with acid-in that it reatly reduces the amount ofhandling of the ottle and reduces the liability of getting acid upon the'hands.

What I-claim as my invention and desire ,to ,s'ecure by Letters Patent is:

In a fire extinguisher,- the' combination of a casing having an u wardly opening neck with an internal seat or 'a'ring, a ring supported on saidseat, a pair of rodsde endin o'm' thering, a bottom supported y sai' rods, a second rial, having their upper, ends diverging and terminating below and free from said ring,

air of rods of spring mateand each havin an inwardly projecting shoulder, I a bott e adapted to pass freely through said .ringlwhile said ring is on-said seat, and being eld upon said bottom by said shoulders with the bottle mouth upward, said shoulders being adapted to also support said bottle in a partly Withdrawn position, with its mouth projecting above the ring; While-said ring is on said seat, and the bottle holder formed of said ring, rods and bottom being adapted to be lifted bodily.

from said casing with said bottle. Signed at Chicago this 28th day of April 1906.- v JOSEPH MQMILLER.
