GEORGE w; BANKER, OF BROOKLYN, NEW YORK.

NOZZLE, STOPPER, AND SPOUT.

SPECIFICATION forming part of Letters Patent No. 245,047, dated August 2, 1881.

I Application filed September 15, 1879.

and spout for metallic cans or other vessels,

and particularly for those intended for use in the shipment of oils and other fluids; and it consists in a nozzle, stopper, and spout composed of the parts having the form, and combined and arranged to operate, as hereinafter particularly described. 7

Figure 1 is a vertical central sectional view of the parts embodying my invention, and showing the spout and nozzle tightly closed by the stopper, whereby the can is closed and in shape for transportation. Fig. 2 is a similar view of the parts, showing the stopper removed and with the spout held erectupon the nozzle when the can is open, and its contents may be discharged through the nozzle; and Fig. 3 is a similar view of the parts, showing the spout wholly removed and the nozzle'closed by the stopper.

A is the nozzle, which preferably has the wide circumferential flange a, by means of which it can be soldered to a suitable opening in the can-lid. The nozzle is furnished with a screw-thread, or, upon its exterior face, as shown, and has an annular recess, a formed about the central opening orvent, a in its top plate, adapted to receive the packing-ring a, which may be of cork or other suitable material.

B is the spout, preferably in the form of a goose-neck, as shown, and atits lower or butt end it is provided with the annular flange b, having the upwardly-turned shoulder or pro.- jection b on its upper surface, and the downweirdly-projecting edge b ,which edge I)? is adapted to fit down upon the packing axwhen said spout is erected upon the nozzle over the opening a thereof, as shown in Fig. 2.

O is a cap having a central opening, 0, in its top, adapted to admit the passage'through it of the spout, and withaserew-thread, c, on its interior face, whereby it may be screwed down upon the nozzle, as shown. When said cap is thus screwed tightly down upon thenozzle around the erected spout the under face of the top of said cap will impinge upon the shoulders I) of the flange b of the spout, and the edge Z; of said flange will thus be forced tightly down upon the packing-ring a, and a joint between the spout and the nozzle be thus constituted, which will prevent any leakage at this point. When the parts are thus arrau ged, as shown in Fig. 2, the contents of the can may be freely discharged'through the spout.

The diameter and dimensions of the opening a in the top of the nozzle should be such as will permit the spout B to be passed in an inverted position wholly through said opening, up to the line of the flange b. When itis desired to close the nozzle the spout B is removed by wholly unscrewing the cap 0, and the spout is then inverted and passed downward through the opening a in the nozzle until the shoulder 12' of its flange b rests upon the packing a*, as shown in Fig. 1.

D is a stopper, which is in the form of a disk, having an annular downwardly-projecting flange, d, and is of a somewhat greater diameter than the flange b of the spout. This stopper is placed over the butt-end of the inverted spout and incloses the flange 12 thereof, and the rim of'its flange d impinges upon the packing a, as seen plainly in Fig. 1. The cap 0 is then screwed down upon the nozzle, and the under face of its top will press upon the upper face of the stopper, and thus force said stopper down, so that the rim of its flange d will fit closely upon the packing a, and so that the under face of the stopper will press upon the upturned edge I) of the flange b, and thus act to also force the shoulder b of said flange b down upon the said packing a. The spout B will thus be conveniently stowed wholly within the can, and the can be tightly sealed at its nozzle, and therefore be in shape for transportation without danger of injury to the spout or the liabilityof the leakage at the nozzle of the contained fluid, the opening or vent a of the nozzle being doubly sealed by the shoulder 12 of the flange of the spout and the flange d of the stopper, both forced and held closed by simply placing the stopper D over the opening a with its flange d resting upon the packing a, and the cap 0 be then screwed onto the nozzle, when the said stopper will 5 be forced down and its flange will be pressed tightly upon the said packing, as scenin Fig. 3. I do not claim, broadly, the combination,with a can or other vessel, of a nozzle having a top plate with a central aperture and packingto ri-ng,-a screw-cap, anda spout havinga flange upon its butt-end; but I desire to limit my claim hereunder to the specific parts having the peculiar form, and constructed and combined to operate as herein particularly de- 15 scribed.

What I claim as my invention, therefore, and desire to secure by Letters Patent, is-

The combination of the screw-threaded cannozzle A, having the central opening, a, of the dimensions specified in its top plate, and the 20 packing ring a*, together with the spout B, having flange b, with the shoulder b, and downwardly projecting edge I), the screw cap 0, and the stopper D, having the annular flange d, all constructed and arranged to operate sub- 2 5 stantially as and for the purpose described.
