`.and in Great Britain'August 28,1929 s claims. (o1. ies-f2)k z This invention relates to fire extinguishers of thekind employinga chemical agent or fluid contained in areceptacle of frangible materialV such' as glass. The-chief object-of thepresent invention is to provide an improved re extinguisher of the above kindthat ,is particularly applicable for .usein conjunction with prime movers either stationary orcarried on road, rail or othervehicles. v A

According to the invention the 'receptacle containing the chemical re extinguishing agent or uidisV completely mounted in a. supporting .unit comprising a bracket member kor holder adapted to be secured to any convenient support, for eX- ample to a stationary part .within the vengine compartment or" a vehicle,l Vmeans operable from a distance being provided wherebyy in rthe-event of fire, the receptacle can be ybroken to release the chemical agent or uid `Thesaid-bracket member preferably carries the receptacle iny a readily removable manner `so that the latter may be used, when required,` as a portable fire extin,

guisherV and the construction ofthe bracket member may beof an adjustable;nature,;such as of two or more part form, so -that the location of the receptacle relatively toi-the engine of the vehicle for example maybe altered tosuit varyingconditions which obtainfwith dierent types of such vehicles with the object; of vreleasingthe liquid in as close proximity .to the seat of the fire aspossible. p In order that the said invention may be clearly understood and readily carried into effect the same `will now be describedmore fully with reference to the accompanying drawing in which:-

Figure l is a front viewofapreferred formof the bracket member, receptacle, and means for breaking the receptaclev to rrelease t the contents thereof. 9 Figure 2 is aside elevation of Figurejl, and Figure 3 illustrates a detail tobedescribed. The supporting unit l.or bracket member comprises an elongated support A adjustably secured to which is a casing B for the receptacle C, IIhe support A is in the form of an open ended trough having apertured wing plates a at one end Whereby the support caribe secured' to theV dashboard within the bonnet of a motor-car and apertures a? through one of which a bolt D passes which secures acasing carrier E to the support. The carrier is secured to the casing at its upper ends and is shaped at its lower end so as to t the support A and so that it may be secured to they support in the position illustrated in Figures 1 and 2 or at right angles thereto.. The apertures a2V cle.

permit adjustment of the carrier and casing longitudinally of the support. .The receptacle C and thecasing B are in the forinof cylinders andthe latter comprises a receptacle holder Z) and a closure b1 therefor, the closure being hinged tothe 60 holder at b2 on anhoriaontal axis and provided with a fastener o3. Secured by adhesive or otherwise within the holder are two semi-circulary and fairly thick strips F ofv resilient material, preferably'rubber or, the kind known by the registered 65 trade mark Sorbo, and within the closure two K corresponding strips F1 Aare secured so that when the receptacle C'is .placed in the holder and the closure .isfastened in position the strips F, F1, will be compressed andi/vill firmly grasp the recepta-l 7C' Opening lthe closure will release the receptacle so that yit can be used as a portable re eX` tinguisher.. Located within the casing and around'the middle of the'receptacle isa band H of piano wire bent inwardly into projections h. The wire is threaded atone end which is secured by nuts h1 tothe carrier. E. The other end of the p wire is attached by a connection j to one end of a wirefJ forming part of a B wdenwire device I (the Word Bovvden being a registered. trade 80 mark) the outer jacket Jl or" which istattached to the carrier E by a connection jl. The other end of thev wired is connected to a pedal lever or other suitable device (not shown)V whereby it may be 'operatedsothat'thepiano wireis con-y o A tracted about the receptacle which is broken or crushed by theprojections h thereby releasing the fireY extinguishing agent or fluid which flows lthrough an aperture K in the Vlower part of the holder and from the ends thereof. Any ofthe nre extinguishinglagent or vnuid falling into the support A escapes through the perforations a2.

lf desired Athe "arrangement may be such that all vthe iluidfalls into athe support A which may have numerous perforations therein.

In a modified form of the invention illustrated inl Figure the manually operated means comprise anla'rrn mounted on a pivot R1 'carried by the support A.- The connecticny' is secured to the 10U rear end of thev arm and when the latter is operated it'sront end enters through the aperture K in 'thevholder b and breaks the receptacle. *'Iphe pivot is mountedin apertures R2 in the sides of the support A, the apertures crrespondin'g to the 105 perforations a2 so as to permit adjustment of the arm R in accordance with the positiony of the holder respect to the support. The connection jl, can besecured adjacent toanyone of the perforations a2. 110

'What I claim and desire to secure by Letters Patent of the United States is:-
