THOMAS F. HANDLY, OF ALLEGHENY, PENNSYLVANIA.

FIRE-EXTINGUISHER.

Specification of Letters Patent.

Patented Apr. 5, 1910.

Application led December 21, 1905. Serial No. 292,757.

To all whom it may concern:

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

This invention relates to certain new and useful improvements in tire extinguishers, and relates more particularly to that type of apparatus commonly known as a chemical ire extinguisher.

My invention aims primarily to provide an adjustable cage for acid receptacles, such as are employed in combination with a suitable casing containing an alkali solution, to produce gas having expelling force suiicient to extinguish a fire. In this connection, I have devised an adjustable cage adapted to support bottles of various sizes and contours.

To this end, the invention in its broadest aspect involves in combination with a cage, positive and reliable means for adjusting the cage and supporting a bottle or receptacle within a confined space relative to the casing, also means for eiiecting a dischargebf the acid when the fire extinguisher is inverted whereby the alkali solution or fluid contained within the extinguisher will be thoroughly impregnated with the acid and form an extinguishing solution.

Another very important feature of my invention resides in the simplicity of construction which I have used. throughout the various forms struction employed entirely dispensing with the cumbersome cages heretofore used.

With the above and other objects in view, which will more readily appear as the nature of the invention is better understood, the same consists in the novel construction, combination and arrangement of parts to be hereinafter more fully described and claimed, and referring to the drawing accompanying this application, like numerals of reference designate corresponding parts throughout the several views, in which z- Figure l is a front elevation of my improved cage for tire extinguishers, illustrating the same detachably secured to the lid or cap of an extinguisher, Fig. 2 is a vertical sectional view of the same, Fig. 3 is a verof the invention, the simple con-V.

tical sectional view of a movable stopper used in connection with the acid rece tacle of the cage, Fig. 4 is a cross sectiona view taken on the line -m of Fig. 1 looking in the direction of the arrow of said figure, Fig. 5 is a. similar view taken on the line y-y of Fig. l, looking in the direction of the arrow of said figure, Fig. G is a vertical sectional View of a modified forni of sto per, Fig. 7 is a front elevation of a slight y modified form of cage, Fig. 8 is a similar view of still another form of cage, Fig. 9 is a side elevation of the same, Fi 10 is a cross sectional view taken on the Iine aa of Fig. 7, Fig. 11 is a detail side elevation of a portion of a cage, illustrating the same to be used in connection with an adjustable retaining ring, Fig. l2 is a plan of a retaining ring, Fig. 13 is a bottoni plan of a poi'- tion o f a cage equipped with an adjustable retaining ring.

It is well known, that bottles of any given capacity or chamber-area are, as a rule, manufactured in different shapes, heights, etc., and the capacity or chamber-area oi one bottle may be exactly the same as that of another bottle of an entirely different shape. It is the aim of my invention to provide a cage for fire-extinguishers with means for engaging, and steadily-supporting, bottles of different diameters, heights, cross-sectional contours, or other diiering features, but having the same internal capacity or chamber-area- In the accompanying drawing, I have illustrated a conventional form of cap or lid l, such as is generally used upon chemical fire extinguishers, the cap bein provided with a depending screw threade stem 2 in order that it may be secured to my improved cage. It has been the practice to provide the cap with a ca e which supports an acid bottle or receptac e, while the casing is provided with an alkali solution adapted to be impregnated by the contents of the bottle or receptacle, when the casing is inverted.

My invention particularl resides in the construction of an adjustab e cage which is detachably connected to the cap or lid 1 of the extinguisher, and in the accompanying drawings, I have illustrated various forms, all of which are within the scope of the invention, and are adjustable in one respect or the other.

Reference first being had to Figs. 1, 2, 4 and 5, it will be observed that my improved cage consists of a mixing cup 3 having depending arms 4, 4 and 5, 5, said arms being slightly bent outwardly, as at G, 6. The mixing cup is provided with a central screw threaded recess 7 adapted to receive the screw threaded stein 2 carried centrally of the cap or lid 1. The mixing cup, which is preferably cylindrical, but may be any shape, is ada ted to bear against the underneath face o the cap 1 when secured thereto, the top of the mixing cup forming a substantial bearing surface when the extinguisher is inverted. The depending arms 4 adjacent to the mixing cup are provided with a retaining ring S), said ring being supported centrally of said arms by outwardly extending ribs 10, l0 carried by the arms 4, 4.

In practice, the mixing cup, together With the arms 4, 4 and 5 5 and the retaining ring are formed integral and to further brace the arms, I employ a transversely disposed frame 11 which is carried by the arms 4, 4 and 5, 5 beneath the retaining ring 9 the frame 11 being preferably arranged a slight distance below Where the arms are bent outwardly, as at 6, 6. A particular feature of my invention resides in the formation of the frame l1 which is substantially rectangular in plan view, the frame being formed by side rails 12, 12 and end rails 14, 14, the juncture of said rails forming rectangular corners 15, so as to embrace a bottle or receptacle substantially rectangular in cross section. The side rails 12, 12 are curved outwardly, as at 16, 16, to embrace a bottle 17 of cylindrical form as illustrated in dotted lines in Fig. 5 of the drawings. The end rails 14, 14 are also formed with out- Wardly extending ortions 18, 18, thus adapting the frame 1 to also iit a bottle 1E) rectangular or oval in cross section. By the construction of the frame 11, it will be observed that almost any shaped bottle or receptacle can be mounted in the frame 11 and retained therein and prevented from becoming displaced from my improved cage.

The lower ends of the arms 4, 4 and 5, 5 form legs to support the cage and the cap 1, when they are disconnected from the casing of the extinguisher. In connection With the lower ends of the arms 4, 4 and 5, 5, I use an adjustable bottom plate 20, forming a support or rest for the bottle said plate being circular in lan vieW and having its edges provided with slots 21, 21 to receive the ends of the arms 5, 5, and with bayonet shaped slots 22, 22 to receive the lower ends of the arms 4, 4. The ends or legs of the arms 4, 4 have their inner or confronting faces provided with a plurality of notches 23, 23 and in these notches the shoulders or sides 24, 24, of the bayonet shaped slots 22, 22 are adapted to engage. The plate 20 is adapted to support the bottle or receptacle 25 mounted in the cage, and is positioned according to the depth of the bottle or receptacle.

In placing an acid receptacle or bottle Within the cage the neck of the bottle or receptacle extends upwardly through the rctaining ring 9, While the body of the receptacle or bottle is embraced by the frame 11 and supported by the plate 20. It Will be observed that tlie top of the bottle protrudes slightly into the mixing cu 3 and in connection with the neck of tie bottle or receptacle I use a stopper 26, said stopper be ing constructed of lead or a metal not aii'ected by the acid or contents of the bottle or receptacle 25. The stopper is adapted to fit loosely over the top ot the bottle and is provided with a depending stem 27, which is detachably secured to the stopper as at 28, in order that the stem may be removed and a larger stem placed therein in case a larger sized bottle or receptacle is used, the stein being ada ted to lit Within the neck of the bottle an revent the stop er from beconiin displaced relative to tie cage or receptac e, as Will be presently described. In some instances the stem 27 may be provided With a sleeve 29 in order to increase tlie cross area of the stem to fit larger sized receptacles or bottles than that shown.

Reference will now be had to Figs. 7 and 10 of the drawin s, wherein I have illustrated a less comp icated structure than the cage heretofore described, the arms 5, 5 and the frame 11 being entirely dispensed with. The mixing cup 30 is provided with two dependin arms 31, B1, and a retaining ring 32 similar to the cage heretofore described, and the lower ends of the arms 31, 31 are connected together by a plate 33 and provided With a plurality of inwardly extending lugs 34, 34, which serve to support a false or adjustable bottom 35. The pe riphery of the false or adjustable bottom "35 is provided With diametrically opposed recesses 36, 36 to engage between the lugs 34, 34 of the arms 31, 31, said recesses corresponding substantially to bayonet shaped slots. The plate 35 is provided With four upwardly extending angular lugs 37, 37, the edges 88, 38 of said lugs forming a surface to embrace a c lindrical bottle, While the angularity of t e lugs forms a surface to embrace a rectangular or oval receptacle. The lugs are ada ted to embrace the bottom sides of a bott e or receptacle, While the retaining rin 32 is adapted to embrace the neck of a ottle or receptacle and when a bottle or receptacle is properly positioned Within the cage, it will be observed that it will be impossible for a bottle to become displaced from the cage. unless the false bottom or plate 35 is removed from its supporting lugs 34.

A slight modification of my improved cage for extinguishers is illustrated in Fig?. 8 and 9 of the drawings, where it will be o served that depending arms 39, 39 of the mixin cup 40 are of a less length than the arms eretofore described, but still support a retaining rin 41 similar to the rings 9 and 32. n or er tosu port a bottle between the arms 39, 39 an Within the retain ing ring 41, I use a plate 42 similar to the plate 35, but provided with upwardly extending arms 43, 43 instead of the recesses 36, 3G of the plate 35. The upper ends of the arms 43, 43 are enlarged, as at 44 and provided with a plurality of transverse Slots 45 which are adapted to engage pins 46, 46, carried by the enlarged lower ends 47, 47 of the arms 39, 39. After a bottle or receptacle has been placed within the retaining ring, 41, the plate 42 can be moved to en age the bottom of the bottle or receptacle an the arms 43, 43 locked in engagement with the depending arms 39, 39 of the mixing cup 40. By providing a plurality of slots 45, the plate 42 can be easily adjusted to engage bottles or receptacles of various depths, to hold them in proper position relative to the retaining ring 41.

Another feature of my invention resides in making a portion of the cage, namely the retaining ring, adjustable this feature being clearl il ustrated in Figs. 11 to 13 inclusive. he arms 48 48 of the mixing cup 49 are provided with inwardly extendin pins 50, 50, said pins engaging slotted curve plates 51, 51 carried 'b the ribs 52, 52 of a retainin rin 53. Tlie retaining ring 53 can be adjuste relative to the mixing cup 49 and when a bottle or receptacle havin a short or long neck is mounted in either o the frames previously described, the retain ing rin can be properly adjusted upon the neck o the receptacle to securely hold the same and limit the movement of the bottle or receptacle within the ca e.

I believe the o eration o placing a bottle or receptacle wit in my im roved cage to be obvious, but in order t at t e movement and operation of the extinguisher, when inverted may be fully understood, I will assume that the bottle is held in the position shown in Figs. 1 land 2 of the drawings. When the extinguisher is inverted, the sto per 26 will descend into the mixing cup of t e ca e and the contents of the receptacle ori bottIe will be precipitated into the mixing cup, and will ceminingle and impregnate the alkali solution carried in the casing of the extinguisher. The position of the bottle or receptacle within the retaining ring of the cage ma ermit of a slight movement of the bott e, ut not sufficient to permit the neck of the bottle to rest upon the bottom of the mixing cup, thereby permitting the con tents of the bottle or receptacle to enter the mixing cup and. the casing of the extinguisher.

From the foregoing description, it will be observed that I have devised novel means for supporting a bottle or receptacle in a proper position relative to the casing or cap of an extinguisher, said means being adjustable, thereby not necessitating the use of one form of bottle.

The modified forms of construction illustrated in Figs. 7 to 13 inclusive, greatly simplify cages heretofore used, consequently reducing the expense of manufacture and freeing them from all danger of being improperly assembled in an extinguisher.

In connection with the adjustable bottom plate 20, I desire to call attention to the fact that in connection with the false or adjustable bottom 35 together with the lugs 37, the late may be termed irregular, owin `to t e fact that it can. support bottles o various contours, this being accomplished by making the lu of a sufficient height to snugly engage t e lower edges of a bottle or receptacle and prevent the same from shifting upon the p ate 35. The means for supporting the plate 35, namely the lugs 34, are carried by the inner faces of the depending arms 31, 31, but it will of course be understood that these lu s can be carried by the outer faces of the date 35 and the recesses 36 ma be of a sugicient size to engage said lugs,th1s construction simply providing a larger bottom plate than that shown.

I also desire to call attention to the detachable depending stem carried by the stopper, this stein being employed to govern the flow of acid from the bottle or receptacle of the cage, the cross area of the depending stem being reduced when a lar er flow is desired and enlarged when a esser flow from the bottle or receptacle is necessary. As some bottles have larger necks than others, I have found it necessary to detach ably connect the depending stem in order that the same may be changed to govern the fionT from the bottles or receptacles used.

The advanta e resulting in providing a cage capable o receiving and steadily supporting bottles of different diameters, or cross-sectional contours, or of different heights but all of the same internal capacity or chamber-area, will be a parent, since it is not always possible to o tain a bottle of a desired capacity in a shape to iit a receptacle or ca e constructed so as to receive only a bottIe of a specific sha e. For instance, if the extinguisher is s ipped from the factor with a bottle of five ounce capacity and o circular cross-sectional form, and the cage would accommodate only bottles of this form it will readily be perceived that should the bottle be broken during the use of the extinguisher, or at any other time, it would be a serious inconvenience to the owner, if he were unable to re-charge With any other bottle oi the same capacity, than one of the same shape and contour as the original bottle. With the construction of my improved cage, all such inconvenience is climmated, and danger of inability to promptly recharge the extinguisher is obviatcd.

I preferably construct my improved cages together with their appurtenant parts o a material not susceptible to the chemical action of any Huid or ingredients in which they may bc subn'ierged, and While l have herein illustrated the preferred form of construction, it is obvious that such changes in the minor details, size and proportion of my improved cages, as are permissible by the appended claims, may be resorted to Without departing from the spirit and scope of the invention.
