Application filed October '7, 1897. Serial No. 654,426; (lilo model.)
To allhwhom it may concern.-
Be it known that I, GEORGE F. TONG, a citizen of the United States, residing at Sacramento, county of Sacramento, State of California, have invented an Improvement in Can- Faucets; and I hereby declare the following to be a full, clear, and exact description of the same.
My invention relates to a combined discharge-faucet and air-supply device which is especially designed for use in conjunction with air-tight cans, and particularly with that class of cans in which coal-oil, gasolene, naphtha, and similar products are sold and.
from which it is desirable to draw thecontents in such quantities as may be needed without the trouble of transferring to other cans or receptacles.
My invention consists in the parts and the constructions and combinations of parts hereinafter described and claimed.
In the accompaning drawings, Figure 1 is a vertical section showing an inverted can and my faucet connected therewith. Fig. 2 is a sectional view of the faucet-plug. Fig. 3 is a View of the can incondition for ordinary transportation with its sealing-cap in position.
In putting up oil, gasolene, and that class of products for the market it is common to employ rectangular cans A, which contain about five gallons.- In one corner of these cans is fitted a screw-threaded sheet-metal nozzle having a closing-cap which-retains the contents for transportation. Various attachments have been made for the purpose of drawing thecontents of these cans directly through the nozzle; but it is difficult to provide a draw-0d cock of any description which will not leak or drip and which will withdraw the entire contentsof the can.
In my invention I make the nozzle Bscrewthreaded upon the outside to receive the sheet-metal cap B',which fits overit and screws down to form-a closec'a'p or covering for the nozzle in the usual manner.
nozzle is diverged, as shown, so that the cap C. This faucet has the end threaded to fit the threads B and it has a flange, as shown The base of-the at O, with an annular groove or chamber into which is fitted a cork or other suitable pack-' ing D, which is not readily attacked by the liquid contained in the can. When the faucet 'is screwed down, this packing-ring fits snugly upon the outer end of the nozzle B and makes a tight joint therewith out of line of direct pressure of the'liquid, and this will prevent leakage at this point. I
The faucet-barrel 0 extends a short dis tance in a straight line with the nozzle B, then turns at approximately right angles, so as to carry the key orplug E, which is fitted intdthis portion, outside of the edge of the can, and the faucet-barrel then turns again into a position approximately parallel with sentiallya reverse curve. After having been screwed into position the can A is inverted and set upon any convenient shelf, the can projecting sufiiciently beyond the edge of the shelf to make room for the nozzle B and the faucet to extend down in front of the shelf.
Through the horizontal portion of the fancet-barrel is. made the tapering seat portion, which is adapted to receive the plug E. This plug is ground and fitted. into the tapering seat in the usual way for faucets, and has two openings made through it, one. opening c in c' in the line throng-lithe faucet above the opening e. This passageis for the admission withdrawn and prevent a. vacuum within the In order to provide for ,ftheadmission of air, I have shown a pip'e F, which extends into the interior of. the can to .apointvery near nozzle. This pipe extendsdown into the vertical portion of the barrel .0, then turns in line parallel with the horizontal portion forming'a connection through the passage e inthe into the vertical discharge portion of the barrel, asshown. I It will be-understood that this passage may be made in. any suitable manner. .I have found it cheaper ,andmore conto the main faucet barrellQ.

the cap B is reiiiov'edftheiaucetbarrel is in.-
troduced and screwed into place, the pipe F extending down to near the bottom of the can A when the faucet-barrel has been seated, so
as to make a tight joint upon the washer D. The can is then inverted and set upon a shelf with the faucet projecting downwardly from the nozzle. In this condition it will be manifest that some oil will at first remain within the air-pipe F, and when the cock is turned for the first time if no other provision is made some of the oil within this air pipe would spurt out through the small opening G. The oil in this pipe F will be prevented from spilling out through the hole G, because any oil in the part of the pipe between the hole G and the interior of the can will be sucked up by the vacuum produced by the withdrawal of the oil from the interior of the can. The small body of oil which remains in the part F of the pipe below the opening G will be drawn downward by the suction produced by the weight of the body of oil flowing out through the lower curve of the fancet. As soon as the pipe F is once clear of this oil air will be admitted through the opening G and will pass pp throng the pipe F into the upper part of the can, thus taking the place of the oil as fast as the latter is withdrawn. The two passages e e being in line with each other it will be manifest that both the discharge and air-inlet openings will be opened and closed simultaneously. When the plug is turned to cut off the liquid discharge and the air supply, air will pass through the opening G into the discharge end of the faucet, thus allowing the liquid therein to flow out at once and preventing drip.
As the faucet-plug becomes worn and sinks into the tapering seat in which it is fitted, it is necessary to provide some compensation for this. I therefore make the discharge- Z passages e e through the plug of an oval shape 5 as plainly shownin Fig. .2,and; this keeps the passages always in proper line with the discharge and air-inlet openings, although the plug may by wear settle a conup and down,
siderable distance within its seat.
Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-
1. The combination with a can having an exterior and interior screw-threaded nozzle projecting from one end, a faucet-barrel, one portion of which is screw-threaded to fit the nozzle and provided with an exterior closingaxially in line joint, said first section being with the nozzle whereby the contents of the can are discharged directly thereinto, a hori-' zontal outwardly-projecting portion of the faucet-barrel having a closing-plug fitting a seat transversely across it, a downwardlycurved discharge portion, an air-pipe having a vertical portion extending interior toAahe vertical portion of the faucet-barrel apd to the opposite end of the can, and a horizontal portion extending above the horizontal portion of the 'fauoet-barrelpassing through the plug-seat having the outer end curved downwardly and entering the downwardly-curved discharge portion of the faucet-barrel, and a faucet-plug turnable'in the seat having independent openings coinciding with the discharge-passage of the faucet-barrel and the superposed air-passage, whereby the turning of the plug opens or closes the two simultaneously.
2. Areversely-curved faucet-barrel having the inner end adapted to fit and form a joint vertically with the corresponding vertical nozzle of an inverted containing-can, a horizontal outwardly-projecting portion of the faucetbarrel, a downwardly-projecting discharge end, a tapering seat with controlling-plug fitting therein within the horizontal portion of the barrel, an air-pipe extending from the upper part of the interior of the reversed can downwardly within the first portion of the faucet:harrel, thence extendin horizontally approximately parallel with t e horizontal portion of the faucet-barrel and above it, thence curving downwardly and entering the vertical discharge portion ofthe barrel, a faucet-plug having openings corresponding respectively with the main opening of the faucet-barrel and with the opening of the supplemental air-pipe whereby both passages are opened or closed simultaneously, and an opening in the outer portion of the smaller pipe, whereby air is admitted through said pipe to the interior of the can while the liquid passes out through the main faucet-barrel.
3. A reversely-curved faucet-barrel having the inner end of the vertical portion adapted to fit and make a tight joint with the corresponding nozzle of an inverted can, a correspondingly-shaped air-pipe extending upwardly to near the top of the inverted can and above the horizontal portion of the fancet, a plug fitting a seat in said horizontal portionhaving openings corresponding with and controlling the liquid-discharge and airinlet passages, an opening in the air-pipe exterior to the controlling-cock whereby air is admitted into the can as the liquid escapes, said air-pipe being bent to enter the discharge end of the faucet whereby the flow of the liquid produces a vacuum in said pipe and prevents the escape of any liquid therein through the air-inlet opening.
In'witness whereof I have hereunto set my hand.
GEO. F. TONG.
