T 0 all whom t 'mrtg/concern: Y j c Beit known that I, EARL XV. 'lVINi-rNs, a citizen ofthe United States of America, residing atv Detroit, in the county of TWayne and State of Michigan, have invent-ed cer-y tain new and useful improvements in Jfinti-- freezing Plugs, of which thefollowing is a specification, reference being had therein to the Y accompanying drawings.
This invention relates to safety plugs for liquid containers and the object of the invention is to provide a safety device applicable to4 all liquid containers to prevent bursting thereof, through freezing of their contents, said device having a special value as applied to water pipesand Vto the water jackets of explosive engine cylinders.
In the drawings:
Figure -1 is a sectional elevation showing the application of the invention to an ordinary jug or a bottle;
Figure 2 is a cross section of the water jacket of an engine to which the invention is applied;
Figure 3 is arsectional view showing the application of the -invention to a water pipe.
Figures 4 and 5 are views of two diaphragms weakened to insure bursting when subjected to predetermined pressures.
In these views the reference character l designates a jug or bottle having a cork or stopper 2 engaging its mouth. The upper end portion of a tube 3 iseXtended centrally through the stopper Q, and fixedly secured to said stopper in any suitable manner. y Said tube extends downwardly into the central portion of the receptacle land its lower end is there closed by a cap 4 formed of a material having a considerable less strength than the wall of the receptacle. Thus, when the contents'of the receptacle begin to freeze,
t-he resultant pressure within the receptacle` Vwill fracture the cap l rather than the receptacle itself and the pressure will'then be relieved.
Referring now to FigureQ, 5 designates the, water jacket of an explosive engine, and 6 is a tubular plug having screw-threaded engagement with a wall of said water jacket adjacent the bottom thereof, said plug terminating at its inner end in the central portion of the lower part of the water jacket. A clamping ring '7 is screwed upon the inner end of said plug and serves to clamp the disc shaped closure 8 against said end, a packing ring 9 being preferably engaged between the Y marginal "portion of said lclosure and said ring'.' Thel disc 8, is formedof a material having ample strength to resist suchpressures as may ordinarilyf arisel within the 'water jacket chamber, said Idisc nevertheless,
being considerablyweaker than the wall'of i the water jacket. .Thus said disc may be v formed of lead or some other soft metal proportioned in thickness to insure yielding upon creation within the water jacket charnber of a pressure considerably less than that' required to fracture the wall thereof. Thus, when the contentsof the water jacket commence to freeze the pressure will not be permitted y to build up to a dangerous point before fracture of the closure 8 occurs, per- Vinitting the major portion of the water within said jacket to escape through the plug 6. Tn Figure 3, 10 designates anordinary water pipe, and l1 a. fitting interposed in Y said pipe, providing a chaniber'having an area considerably greater than that of the pipe. The wall of said fitting is adapted for screw-threaded engagement by a plug 12,
extending into the central portionof the ittingand provided at Vits inner end with the closure 13' having a predetermined strength considerably less than that of the iitting itself, the construction and mounting of said closure corresponding to that of the plug 6 and closure 8 already described. The plug l2, however may be provided with an internally threaded outer portionl?)a for engagement by a waste pipe 14:, which will conduct the escaping water to any desired point, when bursting of the .closure .13 occurs through anA initial freezing of the waterin said pipe. y
In each of the applications of the invention, as above described, it will be noted that the plug is extended some'distance into the receptacle, this beingdonev for the reason Y' that freezing occurs first adjacent the receptacle walls and therefore will build up a pressure within the receptacle sufficient to break the closure carried by the inner end of the plug before the tempcratureof the liquid in conta-ct with said closurehas been reduced pended upon to yield under the predetermined conditions, and mayl resist the increasing pressure resulting from progressive phragms as shown in Figures 4 and 5, the
former being weakened b-y an `annular chan-V nel 15 andthe latter by partially shearing out its vcentral portion so as to produce :L
'relatively thin neck portion A16 i v VVlmt claim as my invention 1s:
Y n e. device of the class described, the coinbination with a liquid container havingqa-n opening therein, of L hollowy plug engaging the opening in said container, a tube projeeting inwardly from said plugand terminetingY about the center o' said container, a
disk-shaped closure engaging the inner end of Vsaid tube and having a predetermined strength less thanthat of said tube and the Wall of saidV container, and a clamping ring engaging the edges of said closure land holding ythe latter in place, said closure being' weakened adjacent to the edges thereof.
In testimony whereof ai'x my signature.
