FIRE-EXTINGUISHER.

SPECIFICATION forming part of Letters Patent No. 682,069, dated September 3, 1901. Application tiled October l, 1900. Serial No. 31,679; @lo model.)

To all whom t may concern:

Be it known that I, THOMAS F. I-IANDLY, a citizen of the United States of America, residing at Allegheny, in the county of Allegheny and State of Pennsylvania, have invented certain new and useful Improvements in Fire-Extinguishers, of which the following is -a specification, reference being had therein to the accompanying drawings.

This invention relates to certain new and useful improvements in nre-extinguishers, and has for its object to construct an'extinguisher wherein the maximum neutralization of the acid with the liquid may be obtained, the acid contained within the acid-receptacle being discharged into the liquid at a point some distance from the liquid-outlet and a thorough mixing of the acid and liquid attained.

Briefly described, the invention comprises, in connection with the liquid receptacle, which may be of the usual form, a cage which is supported from the closure-cap of the liquidreceptacle, an acid-receptacle arranged within the cage and adapted to float upwardly within the same when the receptacle is inverted, a seal suspended from the closure-cap of the receptacle and depending within the cage to seal the acid-receptacle when in an upright position, and a gravity-lock which holds the acid-receptacle in the sealed position while the extinguisher as a whole is in the upright position, but which breaks the seal or permits the disengagement of the mouth of the acid-receptacle from its sealing engagement with the seal and the acid-receptacle to float upwardly in the receptacle, discharging its contents as it floats when the extinguisher is inverted. Means is also provided for preventing the resealing of the acidreceptacle with the sealing-cap as the contents of the extinguisher are discharged and the acid-receptacle settles upon its seal, all of which construction, with the various other details entering into my invention, will be hereinafter specifically described and then particularly pointed out in the claims.

This application should be considered in connection with a companion application filed by me, Serial No. 683,552, for which Letters Patent were granted November 6, 1900, Patent No. 661,215.

In describing the invention in detail reference is had to the accompanying drawings, forming a part of this specitieation,and where- 5 in like numerals of reference indicate corresponding parts throughout the several views, in Which- Figure l is a side View of an extinguisher, partially in vertical section, showing the acidreceptacle in the sealed position. Fig. 2 is an inverted side elevation, partially in vertical section, showing the seal broken, theJ acidreceptacle having floated upwardly in the cage and in the act of discharging its contents into the solution within the receptacle. Fig. 3 is a detail perspective view of the gravity-lock and seal for theacid-receptacle, together with the closure-cap for the receptacle, the latter being partly broken away to better illustrate the position of the gravitylock. Fig. 4t is a vertical sectional view ot' the closure-cap of the receptacle and of the gravity-lock, showing the latter sealing the acid-receptacle, which is partly broken away.

In the adaptation of my improvements to tire extinguishers of this type I make no change in the ordinary construction of the liquid-receptacle l, the closure-cap 2, and discharge hose and nozzle 3, which parts I have shown to better illustrate the operation of the device.

Rigidly secured to the underneath face of the closure-cap 3 is a cage 4, which in the form herein shown is constructed of four 8 wires connected at their lower ends to a ring or other suitable-base and at a point near their upper ends contracted `toward a common center, s0 as to form the offset or shoulder 5, and the wires extended vertically from this inclined offset or shoulder to the closurecap to form the neck 6 of the cage.

It will of course be evident that I do not confine myself to the construction of a cage made of wires, as described. In practice I have found such form of cage a cheap, simple, and practical one, and therefore illustrate this form in this application.

My improved seal for the acid-receptacle and the gravity-lock for maintaining the seal until such time as the extinguisher is inverted consists of a sealing-disk 7, somewhat in the form of a frustrated cone, provided with an annular iiange 8, extending below the sealing- ICO face 9 of the disk, so as to engage with the periphery of the neck of the acid-receptacle 10. This acid-receptacle 10 is arranged within the cage 4 and is ordinarily in the form of acommon bottle, in which event the annular flange 11, usually provided at the top of botile-necks, will be peripherally engaged by the annular iiange 8 of the sealing-disk. The sealing-disk is suspended from the closurecap 2 by means of a centrally-arranged post 12, secured to the closure-cap centrally thereof and screwed into or otherwise engaging the sealing-disk 7. The acid-receptacle is held in the sealed position during the time the extinguisher is in an upright position by means of a pair of pivoted clamping-arms 14 and a gravity-operating annulus, ring, or collar. The clamping-arms 14 are secured by links 15 to opposite sides of the sealing-disk and are each provided at their lower ends vwith lugs 16, extending outwardly at right angles to the arms proper to form a seat and support for the ring or collar 17. The pivotal connection of the links 15 with these arms is at a point slightly above the central line of their length, and the arms are curved outwardly, as at 18, so as to be engaged by the ring or collar 17 when the extinguisher is inver-ted, the curved ends of the arms when thus engaged by the ring or collar 17 being forced inwardly between the wires or bars of the cage. The arms also carry on their inner faces, at a point slightly below the connection of the links 15 therewith, clamping-lugs 19, having their free ends 2O concave, as shown, so as to fit neatly around or partially around the neck of the acid-receptacle, which, when the bottle form of receptacle is employed, they engage at a point directly below the annular flange 1l of the bottle-neck.

In order to prevent sealing of the acid-receptaclel at a time when the contents of the extinguisher have been almost discharged and the acid-receptacle has been lowered with the lowering of the solution until its mouth reaches the sealingdsk, I provide a link or pin 21, which is pivotally connected to an eye 22, secured centrally of the sealing-face 9 of the disk 7. This arm or link when the acidreceptacle is sealed, the extinguisher being in the upright position, depends or hangs downwardly into the neck of the acid-receptacle, as shown in dotted lines in Fig. 4 of the drawings, and is of a length sufficient to permit its lying upon the annular flange 8, which position it will assume upon the inversion of the receptacle, as shown in Fig. 3 of the drawings.

In operation the receptacle containing the` solution is filled to the desired height. The acid-receptacle has been placed within its cage, which is secured to the closure-cap 2 together with the gravity-lock and the seal, the latter engaging the mouth of the acid-receptacle, where it is held by the gravity-lock, the annulus, ring, or collar 17 resting upon the lugs 16 and holding the clamping-lugs 19 in engagement with the neck of the acid-re ceptacle, as shown in Figs. 1 and 4 of the drawings, with the pivoted arm or link 2l extending down into the neck of the acid-receptacle. The acid-receptacle is thus held sealed as long as the extinguisher remains in the upright position, but upon the inversion thereof the ring or collar 17 falls by gravity into engagement with the curved ends 18 of the arms 14, forcing these curved ends inwardly and the lug ends 16 outwardly,withdrawing the clamp-1 ing-lugs 19 from their engagement with the neck of the acid-receptacle and permitting the acid-receptacle to rise or float upwardly in the cage, discharging its acid as it floats and continuing the discharge of the acid into the solution until such time as the acid receptacle is emptied.

The position which theV elements comprising the gravity-lock assume when the extin guisheris in the inverted position is clearly shown in Figs. 2 and 3, and the position of the same, together with the position of the acid-receptacle when the latter is sealed, is clearly shown -in Figs. 1 and 4 of the drawings, and it is thought a further detailed description of the operation is unnecessary.
