To all whom it nuu concern-.-

Be it known that I, LUDwIe Sol-Ion, a subj ect of the Emperor of Austria-Hungary, residing at Vienna, in the Province of Lower Austria and Empire of Austria -Hungary, have invented a new and useful Improvement in Safety-spouts for Receptacles Containing Volatile Inflammable Liquids, of which the following is a specification.

My invention relates to receptacles for keeping and carrying volatile inflammable liquidssuch as spirits, ether, benzin, sulfid of carbon, and the like; and it has for its object to provide a closing device for the oriiices of such receptacles which in the case of the vapors issuing from the receptacle being accidentlly ignited with certainty prevents combustion from spreading into the interior of the receptacles.

According to my invention the inlet and outlet orifices to be provided with the safetyspout have necks inserted into them, a diaphragm of fine wire fabric or finely-holed sheet metal being interposed into each neck. Between the diaphragm and the receptacle the passage or bore of the neck is by preference narrowed and adapted to be controlled by a cylindric slide-valve screwing into the side of the neck, across this latter, and provided with a conic front end, to which corresponds a seat formed in the side ,of the passage. The free end of the neck has its outside provided with male screw-threads and its inside with female screw-threads in order to admit of a cap being screwed on, the cylindric rim of which has female screw-threads, while its central nipple has male screwthreads. Between the cylindric rim and the central nipple a suitable packing is secured to the ca In t e annexed sheet of drawings, Figure 1 is a sectional elevation of the lower part of a sheet-metal cask the outlet-orifice of which is provided with my safety-spout and Fig. 2 is a sectional elevation of a sheet-metal can, into which the inflannnable volatile liquid is allowed to flow from the cask. Figs. 3 and 4 are sectional views of a screw-cap and screwstopper, respectively.

It will be seen that a neck or tube is soldered into the outlet-orifice a of the sheetmetal barrel 1), the said neck being composed of two lengths c and d, screwed together and finally connected by solder.

Into the inner joint between the two lengths c and d is inserted the diaphragm f, made of fine and dense wire fabric or of finely-perforated sheet metal. This diaphragm is either made of a metal not subject to oxidation or provided with a coating which prevents oxidation, as its being destroyed by oxidation in only one point would render it ineffective.

Between the diaphragm f and the cask I) the passage or bore of the neck is narrowed at gin order to adapt it to be closed by means of a pin or cylindric slide-valve h of greater diameter than the channel g and screwing into a bore crosswise t0 the said channel. The front end of the pin h is made conical and en ters a correspondingly-shaped seat formed in the side of the passage g. It will be seen that by partly unscrewing the pin h one may more orless withdraw its conical point from corresponding seat, and thereby open the passage to any desired degree. The outer end of the valve 7), is protected by a screw-cap j, provided with a hole '5, through which a cord or wire 1 destined to carry a leaden seal as, may be threaded. hen such a cord or wire y is used for preventing the valve h from being opened during transport or storage, the said cord or wire y is also passed through the eye 1:, made integral with the length 0 of the neo The outer end of the outlet-neck is under ordinary circumstances closed by a screwcap 7r, Fig. 3, provided at the center of its inside with a screw-threaded nipple Z. To the female screw-threads of the rim of the cap correspond the male threads of the outside of section cl of the neck, while the male threads of the nipple Z are destined to engage the female threads at the inside of the length (Z of the neck. Between the nipple Z of the cap 7c and its rim the bottom of the cap is at m covered with a packing chosen according to the nature of the liquid to be kept in the receptacle. In Fig. 1 it is supposed that this cap 7c, commonly closing the outlet-neck and provided with a solid bottom, has been removed and replaced by a cap-n, into a central orifice of whose bottom a spout n is soldered. The lower end of the said spout n is again provided with the safety device comprising the tube or neck, consisting of the two lengths c and d and the diaphragm clamped between them.

The can 0, into which the volatile inflammable liquid coming from the cask b is to flow, has its inlet-orifice again provided with the neck consisting of the lengths c and d, between which the wire-fabric diaphragm f is clamped and which is adapted to be closed by a screw-cap k, Fig. 3, with a central screwthreaded nipple Z. The spout p of the can 0, too, has its mouth fitted with. the tubes 0 and d, screwed together and clamping the sievediaphragm f. The screw-plug i), Fig. 4, having a packing 11,, secured to its collar, serves' for closing the spout 9.

With the described safety-stopper one may kindle benzin flowing out from the spout n and allow it to flow in the burning state into the can 0 without any fear of endangering the contents of the can or the cask.

The sieve-diaphragms f in inlet-necks are to advantage made cup-shaped, turning the convex side downward, and provided with a plane sieve-flange, through which the air displaced by the liquid which enters the can or receptacle can escape.

When filling a receptacle provided with the described safety-stop er, care must be taken that the level of the iquid should be placed below the sieve-diaphragm. Any surplus liquid poured in inadvertently should be decanted.

tile inflammable liquids, the combination with the tap-hole of an outwardly-projecting neck, a wire-gauze diaphragm inserted into the outer end of the neck, a spout adapted to be secured to the neck, a wire gauze diaphragm inserted into the outer end of the spout, and a valve adapted to close the said neck between the receptacle and diaphragm,

substantially as and for the purpose described.

In witness whereof I have signed this specification in presence of two witnesses.
