The operation of such stovesreq'uires that the fuel container is. comparatively frequently replaced or. atleast refil,l,ed.- .This involves removal of, the. burner and the parts joined thereto such as a control valve and a support for a cooking vessel.
component of such a certain distance before it closes the valve. which stoves of the kind here involved are generally operated, lock nuts or washers and similar retaining or safety means involving the use of tools and/or requiring a certain technical skill are not suitable.
One of the objects of the Still another object of the invention is to provide a novel and improved safety means which engages the container with a frictional grip when the burner is screwed into position thereby effecting an impositive lock between the burner and the container.
Other and further objects, features and advantages of the invention will be pointed out hereinafter and set forth in the appended claims forming part of the application.
In the accompanying drawing a preferred embodiment of the invention is shown by by way of limitation.
In the drawing:
Fig. l is an isometric view of a gaseous fuel burning stove equipped with safety means according to the inven-' tion.
Fig. 2 is an elevational view of the upper part of the stove on an enlarged scale showing the burner and the parts joined thereto in position ready for screwing the burner into position, and
Fig. 3 is an elevational view similar to Fig. 2, but showing the burner and the parts joined thereto in the screwedin or operational position.
Referring now to the figures in detail, the stove as illustrated comprises a container 1 for a liquid petroleum gas,
Due to the conditions under suchas liquid propane, for example; a burner 3 having a threaded;portion:.3,f forscrewing the burner intothe top off'the container,latcontrolvalvel witha valve member 'Ihislsock'etis provided, with avalve seat 10and an opening 11 inthe side walL. 12 isa, pin, connected to the closing-valve andby. means .of: thispin 12 the valve S'is opened against theaction-ofaspring 13 when the threaded portionfi' of the burner is screwed intothe mounting socketi9... 14 is .a safety valve mounted on 1. 15 are airports-for combustionflsupporting air.
' By way. of. example and without limitation, apparatus like thatrillustrated in Figs. 1, 2 and 3 and described above hasbeen constructeddnwhich. the diameter of the, casing 1 is about fivea-nd one-half inches and'the overall.height isU-aboutasevemand threet-eighths inches, the

unit is secured in position of the entire ensemble is screwed-in position of the burner with frictional pressure as is indicated at 7 in Fig. 3 by the axial deformation of the sleeves.
As is apparent from the previous description, the legs or more specifically the part thereof engageable with the container are axially yieldable. It is evident that the not prevent turning of the burner by an intentionally applied force overcoming the friction between the sleeves and the container wall. As is apparent, the safety means intended, fications in the appended claims.
What is claimed as new and desired to be secured by Letters Patent, is:
1. In combination with a gaseous fuel burning stove having a fuel storage container provided with a burner burner, a cooking vessel support secured to said burner above said container, a plurality of rigid legs each secured at one end to said support and, having an opposite end extending toward the top of said fuel storage container, and elastic sleeves secured to and protruding axially beyond said opposite end of said legs into frictional engageof said fuel storage container to frictionally limit rotational movement of said burner relative to said socket.
2. In a gaseousfuel burning stove including a fuel storage container having a burner mounting socket at the opposite extremity thereof, said socket housing a valve normally biased toward a closed position, a burner thread. ingly secured in substantially sealed engagement within said socket maintaining said valve in an open position to permit the flow of fuel therethrough from said container to said burner, and a cooking vessel support secured to said burner above said container, the improvement including a safety device for impeding the rotational movement of said burner out of sealed engagement withsaid socket comprising, in combination, rigid legs fixedly joined at one end to said support and having an opposite end depending therefrom toward the top of said fuel storage container, and elastic sleeves fitted upon and protruding axially beyond said opposite end of each of said legs, each protruding sleeve portion adapted to frictionally engage with the top of said fuel storage container'to limit rotational movement therebetween.
aezasas 3. In a gaseous fuel burning stove including a fuel storage container having a burner mounting socket at the upper extremity thereof, said socket housing a valve normally biased toward a closed position, a burner threadingly secured in substantially sealed engagement within said socket maintaining said valve in an open position to permit the flow of fuel therethrough from said container to said burner, the improvement including a safety device for impeding the rotational movement of said burner out of sealed engagement with said socket comprising, in combination, a cooking vessel support secured to said burner above said container, rigid legs fixedly joined at one end to said support and having an opposite end depending therefrom toward the top of said fuel storage container, and elastic sleeves fitted upon and protruding axially beyond said opposite ends of each of said legs, each protruding sleeve portion adapted to frictionally engage with the top of said fuel storage container to limit rotational movement therebetween.
