SAFETY-CAN FOR HYDRO'CARB'ON LIQIDS.

To @ZZ whom it may concern:

Be it known that I, FREnEiircii J. BECKER, citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Safety-'Cans for Hydrocarbon Liquids; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the `art to which it 'appertains to make and use the same.

This invention has for its object to pro-- vide a safety or non-explosive can or receptacle for volatile 'combustible liquids such as benzene, gasolene, alcohol, sulfuric ether and the like, the object being to provide a device of this character which may be iilled and emptied from a single spout and in which pressure resulting from generation of gases or vapor due to heat is relieved and in which, furthermore, all parts 'are so secured together as to be capable `of withstanding a relatively high temperature, and consists in the features of construction and combi-y nations of parts hereinafter fully described and claime In the accompanying drawings illustrating this invention: Figure l is a fragmentary top plan view of a can or recep tacle Iconstructed in accordance with my invention. Fig. -Q-is a central vertical section Iof the same. Fig. -3- is a bottom plan view of the spout when removed from the can.

I am aware that a number of cans or receptacles for containing combustible liqnids, such as those above-named,have been provided and that in several thereof a single spout for filling and discharging liquids is employed, but, so far as I am informed, such cans have not been yequipped in certain details with means for permitting free passage of liquid in one direction and air in the opposite direction, nor have such cans, so far as I am informed, been constructed with a view to resisting high temperatures, such for example, as would be capable `of melting solder.

The object of my invention resides in providing means for readily assembling the va rious parts of the device by means other than solder and in the provision of means whereby a free inlet for air above the level of the liquid in the receptacle is attained in such manner as to prevent interference Specification of Letters Patent.

therewith by the iiow ofthe liquid being discharged, and, further in the provision of means whereby the valve stem is protected from injury by accidental dropping of the can.

The body A of the receptacle is 4of the usual cylindrical type made of sheet metal and provided with an inverted dish-ed `bottom B and conical top C, the latter being provided in its apex` with la central opening, the latter bei-ng preferably surrounded by a narrow horizontal flange D. Upon said flange D the similar ai-mula'r horizontal flange E of the spout F is adapted to rest,

said iange E being provided with a plurality `of projections G which rest upon the conical portion of the top C and rare adapted to be riveted to the latter. A sealed joint between the flanges D and E is effected by soldering or brazing the same together in any well-known manner. The spout F extends at an angle to the plane 'of the flange E and, in the instance illustrate'd, said angle approximates 4:5 degrees. Said spout is tapered so as to Icol'itra'ct the saine at its delivery end, the latter being trimmed off yon a horizontal plane and affording a seat for the valve IAI which is rigid with the ogee-curved stem I, the latter being pivotally secured between itsv ends by means of the pin J between parallel projections K on said spout. A spring L coiled about said pin J on opposite sides `of said valve stem I engages said projections K at its free ends and at its middle portion engages said valve stem I to maintain the valve H normally closed. At its other end said valve stem is equipped with a thumb plate M disposed adjacent thephandle N of the receptacle and which is adapted to be depressed to open said valve H. The said projections K project above the highest point in the said valve stem I and in the event that the receptacle is dropped said projections serve to prevent a blow being administered to said valve stem to bend or otherwise distort the same. Below said fiange E is a tubular extension O of said spout F but of smaller diameter and area. The lower portion of the wall of said tubular extension O projects into the spout F at a point lhigher than the plane of said flange E and forms one wall of the opening P through which liquid is adapted to be discharged from the receptacle, said opening lying in the plane of said flange Adjacent said opening there are cast integral with the flange E rivet lugs Y Q which are adapted to enter similarly loy gage the same over a greater area.

:free end the said-tubular extension O is pro- :vided with oppositely disposed flanges TV each of which is provided with an opening to receive rivets U-by means of which the gauze V is. secured inV place to cover the lower end of said tube.

In operationthe liquid is discharged from the opening P but as the latter is of smaller area than the delivery end of the spout and the vfree flow of liquid is further retarded by its passage through the gauze covering said opening, it is impossible for a suliieient Y amount'of liquidto flow from the receptacle toequal the delivery capacityV of the discharge end of the spout and thus afree passage -for incoming air to replace discharged liquid is assured. The incoming air passes f through the spout following theupper wall thereof and' passing thence through the tu-v vrbular extension Orinto the receptacle above the level of liquid in the latter. Y

VIt is; essential that cans of this Vnature shall not only be equippedwith sufficiently Vfine Amesh gauze or other foraminated metal covering all openings to prevent back-fire into the-same but that in the event of lire in a building and consequent subjection of the e Yreceptaclefto highv'temperatures `the'gases 40' and vapors generated shall be permitted to escape to'prevent explosion/due to -high Vpressure and further that'` the meltingfof any solder from'the joints shall not release the parts joined thereby from such secure engagement with each other asV to provide an opening of sufcientarea to permit back Y liash into the same] VHence I provide on eting all parts gether.V

my said can YanV 'outwardly opening valve Y whichv will yieldV topressure within the can and also provide means for effectively rivfof the device securely to- To enable the ldeviceto be made very cheaply and at the same time very `strong anddurable it is essential that the same be `cast in a single piece of a malleable material Vsuch as softV brass vand 'that' allV unnecessary' labor such as punchi'ng'or boring holes 'be vavo1ded as farfa's possible wlnle at the same time adequate means forsecuring the 1 gauze-in placenover*theopenings Vwith ease and rapidity Vbe'supplied. Owing to the l l,fact that each opening through the flange E aifords'opportunity for leakage and further that said flange should be ofasy small diameter as possible to economize soldering I have provided the rivet lugs c ast integral with the whole spout and bordering the discharge opening, said lugs being so arranged as to insure their ready withdrawal from the mold. By means of said lugs I not only save the labor incidental to boring holes and inserting rivets and the subsequent necessity for soldering around said rivets to insure sealed joints but also save additional space which would in this instance be required for the accommodation rofsaid rivets. It will be noted that two of said rivet lugs are practically semi-cylindrical, the flat walls thereof being Vflush with the side portions of the wall of the discharge opening.

In order that the valve be always maintained normally seated distortion of the stem thereof should be prevented and to this en d the projections on the spout are pro` vided and made to project above the highest point in said stem so that in the event that the can is dropped the said projections will receivel all blows which otherwise might distort said stem. It will be noted that the said projections also vreinforce and protect the spout from distortion.

I claim as my invention: i

l. In a receptacle of the kind specified, an inlet and discharge spout mounted upon the can body and communicating with the latter at its point of connection therewith, a straight tubular extension on said spout extending into the can body and communieating with said spout at a point higher than the latters point of communication with said can body, foraminated metal disposed at the. points of communication of said spout andsaid tubular extension with said can body, and an outwardly opening, normally closed spring actuated hand operated valveY controlling the delivery end of said spout.
