Application filed March 6,1907. Serial No. 360,941.

To all whom it may concern:

Be it known that 1, WILLIAM H. McNU'r'r,

' specification.

This invention has reference to valved spouts for var ous kinds of cans or receptacles, and especially relates to what are sometimes termed squirt-cans or oil-cans, al-

though it is especially designed to be used for volatile and explosive fluids like gasolene fluids are employed for cleaning clothing and or naphtha; that are used by printers, for cleaning type and various other things; and also used by tailors and others where such fabrics.

It is an object of the invention to provide a spout member for a can containing a valve that is normally retained tightly closed and will remain open only While pressure is exerted thereon by the user, the valve closing immediately upon the pressure being removed.

A further object of the invention is to pro-. vide a form of valved spout in which when; the valve is closed after use, such gasolenethat does not run out of the spout will pass back into the can, and not remain in the spout member. And in conjunction therewith safety members in the nature of perforated plates or wire gauze are provided on .both sides of the val'vein the spout member.

In the accompanying drawings representing one embodiment of the present invention,

Figure 1 illustrates a filler can in side elevation. Fig. 2 is a fragmentary view enlarged showing in section the valve spout. Fig. 3 is a section on the line 3-3 of Fig. 2. Fig. 4 is an enlarged detail view of a portion of the spout member, and Fig. 5 is a fragmentary plan view of the parts shown in Fig. 2.

The invention is shown in Fig. 1 as applied to a can 8 having a handle 9 and a filling cap 10 at the top. The spout member denoted generally by 11 is shpwn secured to the can top adjacent the cap 10.

The spout member comprises essentially two telescoping tubes, one of which carries the valve seat, while the other is secured to the valve whereby the sliding movement will open and close the valve on its seat. Means such as a coil's ring are provided to normally retain the va ve closed on its seat.

When the members are shifted against the force of the spring, the 'valve is opened and the gasolene can be poured'out upon inverting the can but immediately upon release of the telescoping tube member; the spring will close the valve and no -more gasolene can 1 flow out, and its vapors areprevented from escaping, as well as flame 1s.prevented from access to the vapor in the can.

In the construction herein illustrated, the top of the can has a threaded opening 12, in

which screws a tube member having an enlarged chamber at its intermediate portion. The tube comprises a neck portion 1S atone end connected with a threadedneck portion 14 at the other end, by an enlarged portion 15 constituting a valve chamber. The neck 14 is threaded. to screwinto the threaded openinIg;.12 ini the can, ,that'may be elongated to provide a suficient threading,portion. The neck is screwed into the can until the bottom of the'chamb'er 15 rests .on top of the, can.

A. tube 16 telescopes on'the neck portion 13 and may be provided with a pouring extension 17 that is shown curved and somewhat funnel shaped or reduced. A valve in the form of a disk 1.8 operatesiin the chamber 15 by being secured to a stem'19, connected at the top by a cross bar 20 with the-outer telescoping tube 16; the bar 20 passing through slots 21 and 22 in the neck tube 13,- permitting the outer tube' to slide to-move the valve to and from its seat. A rim 23 is preferably provided at the top of thechamber- 15, being practically an extension into the chamber of the neck 13, which forms the seat for the valve 18; the valve being preferably provided with leather or other suitable washer for tightly closing the opening. The sliding tube 16 may be provided with wings, 24 and 25 for engagement by tirefirigers ofthe operator to move the valve to open position; its movement being limited by the engagement of these wings with the top of the chambered member 15-as indicated in broken lines in Fig. 2. The valve is normally retained closed by a spring. In the construction illustrated a coil spring 26 surrounding the valve stem 19 below the valve, engages an apertured plate 27 screwed into the lower neck 14, the plate having a central bore through which the valve rod slides. The minute openings in this plate form a safety device preventing flame or heat from igniting vapor in the vessel, If desireda gauze cone 28 may be provided on1 the lower side of the ICO plate 27 for a similar purpose. A similar safet member 29 is also placed in the outlet mem er 16, that may be either perforated through the spout tube.

metal or Wire gauze, preferably both.

From this construction it will lie seen that when it is desired to pour from t e can, it is. inverted and the valve opened by pressing on the wings on the slidingrmember, which will push the valve inward om its seat, ermitting the gasolene toflow from the 0 amber Back-draft is eflectually prevented by the two safety members vprovided in the pouring device. The valve being released, will at once seat itself, the remaining gasolene will flow out of the telescoping tube members. Upon righting the can, the gasolene remaining in the chamber portion '15 will flow down into the can through the erforated plate 27 and gauze 28. Should a 're or intense heat occur-near the can, the vapors formed are permitted to es cape by meansof a fusible member provided below the valve, preferably in the chamber 15. As shown in Fig. 4, a disk 30 is secured in an opening in the side of the chamber b a 'fusible ring 31, preferably of solder; he heat will melt this ring and the disk will blow out, permitting escape of the vapors generated. Yet should these vapors ignite they cannot back-fire into the can by reason of the aperture members 27 and 28.

Having thus described my invention, I claim: r

1. The combination with a can, ofv an outlet member secured at an openin in the can and having an intermediate chamo ered part, the

outlet member having a valve closing its admission to the outlet of the chamber. the outlet member having a telescoping portion connecting with said valve, a spring arrai'iged to press the valve against said opening,'and apertured (liaphragms in the outlet:

member, one on each side of'the chambered part.

2, The combination with'a can having an opening therein, of an outlet member comprising .a tubularportionha'ving an enlarged chamber at an'lntermediate part,- a valve opening in the can I opening therein, of a tubular member having -a chamber at an intermediate portion and fitted into said opening, a valve arranged to close the openin from the chamber into the outlet portion 0 the tube, a plate within;-

nute openings extending across the opposite f ,PQIUOII of the tube, a stem for said valve sliding in a bore in the latter'plate, a spout tube shdln on the outlet portion said tube. a cross ar connecting the spout member with the valve stem, the inner telescoping member havin slots through which the cross bar is slidab e to permit movement of the telesco ing member to open and cl'o'sethe valve, an a coil spring on the valve stembetween the apertured plate and the valve valve against its seat.
