.To all whom it may concern.-
Be it known that I, FRANK H. FOWLER, a citizen of the United States, residingin the city and county of San Francisco, State of California,have invented an Improvement in Faucets and Valves; and I hereby declare the following to be a full, clear, and exact description of the same. My invention relates to a dischargenozzle or faucet which may be applied to cans or receptacles of any kind containing liquid from which it is desired to withdraw'the contents from time to time. In the present case I have shown it as especially applicable to cans containing oil.
It consists of a dischargepipe or nozzle with an interior spring-actuated controlling-valve, an air-vent connecting with the nozzle, a means for operatin g the valve and controlling the air-vent simultaneously, and in certain details of construction which will be more fully explained by reference to the accompanying drawings, in which- Figure 1 is an exterior view of the dischargenozzle, showing the application to an oil-can. Fig. 2 is a vertical section through the same. wing its construc- As shown in the accompan A is a nozzle or spout projecting from the can or receptacle, so as to serve for the discharge of the liquidcontained therein, the spout being preferably inclined downwardly and outwardly from the receptacle when the latter is in position to discharge the liquid. The inner end of the spout has a partition B, which closes the upper portion of it, leaving the lower portion open for the discharge of liquid. The upper portion of the partition has a small opening I), which connects directly with an air-passage 0, extending along the inner surface of the plate D, through which the dismade. This air-passage is made just where it connects with the opening band tapers graduallyto its upper end,where is made very small, as shown at c. This is for the purposeof reventing the ingross of'liquid when the spout is opened for ts discharge, the pressure of the air coming ying drawings,
- in through the larger opening at the lower end overcoming any tendency of the liquid to enter the small opening 0 after the discharge has once commenced, so as to produce a vacuum within the can. If a small portion of the liquid should commence to flow through this passage when the discharge first begins, it will pass into the nozzle A and discharge with the main body of the liquid, but this discharge through the air-passage, if any, will cease as soon as the liquid flows sufiiciently to begin to produce a vacuum within the can, after iwhich the liquid will continue to flow through the larger opening and the air replaces it through the smaller one.
In order to control the liquid-discharge, I haveshown a valve or closing-stopper E,Which may be made of cork or any other suitable materialfnot easily acted upon by the oil or other liquid contained in the vessel. This valve is secured to the end of an elastic arm F, the rear end of the arm being fixed to the plate through which the nozzle opens at such .a distance from the valve as to allow the necessary movement to open the valve whenpressure is applied to it, the elasticity of the spring again closing it as soon as the pressure is removed. In order to actuate this device, I have shown a stem G passing through a sleeve H, .havin g its inner end connected with the spring and having a milled head or other means I fixed to its outer end, by which it is easilyjoperated. \Vhen this stem is pushed inwardly, it forces the spring and valve back, and thus exposes the discharge-opening of the nozzle. When released, the action of the spring is sufficient to'close the valve and force the stem outward to its normal position. The stem passes through the air-passage (1, pie viously described, and when the stem is in its normal position it also closes the air-passage, bjeeause it is of suflicient diameter to fill the passage. When the stem is pushed inwardly, so as to open the valve, a portion of the stem, which is cut away or made smaller, as shown at 11, for that purpose, is brought into line transversely with the air-passage, thus making the air-passage continuous. The device may thus be operated by pushing the stem inwardly, so as to simultaneously open the liquid-dischargevalve and to make the air-passage continuous for the inlet of air.
In some cases, as for heavy liquids, I may make the nozzle A large enough at the base to allow the air-vent to pass through the up- ICO gage the inclined surface J upon the sleeve .valve is closedand when it is opened, I have shown a small lug or projection 1 which when the valve is closed may be turned so as to en- H, through which the stem passes, and this will act to draw the valve closely against the inner end of the nozzle or the opening thereto, and thus prevent any discharge or leakage at that point. By turning it in the opposite direction it isbrought in line with a longitudinal slot, or channel 7c, made in the sleeve,
- and the stem may then be pushed'inwardly,
the lug following the channel k. lis a notch madein ,one side of this slot or channel at such a point that when the stem has been pushed inwardly andthe valve fully opened the stem may be turned so as to engage withthis slot or depression, and thus retain the valve in its open position, so that the liquid may bedischarged as long as desired without any need for pressing upon the stem to keep the valve open.
When applied to oil-cans or packages in which the oil or other liquid is sold r01: use, the plate D, carrying the nozzle, valve, and valve-stem, may be soldered or otherwise secured in a depression made in the top of the can, and,-if desired, the exterior projecting parts may be surrounded by a protecting-casing which may have a screw-cap to cover; it similar tQ thOSe ordinarily employed int e tins in which oil is delivered, but this is 0 part of my invention, the latter referring particularly to the nozzle, valve, air-inlet, and control mechanism hereinbefore describe Having thus described my invention, what I claim as new, and desire to secure by Letters,
Patent, is- 1 1. The combination, with a spout or nozzle for discharging liquids from containing vessels, of a spring-actuated valve situated interior to the vessel and adapted to close the inner opening of the spout, a stem connected with the arm of the valve and having a locking-lug, a sleeve on the exterior of the vessel,
through which the stem passes, having a groove or channel and lateral slots or channels into which said lug may be passed,and an air passage connecting with the upper part of the spout or nozzle and extending into the vessel.
2. A device for discharging liquids from containing vessels consisting of a spout or nozzle, the lower portion opening directly into thevessel, the inner end of the upper por ion having an air-passage connected with the yessel by an opening therethrough said passage extending inwardly and upwardly, and having anopening in its upper end of smaller diameter than the one connecting with the nozzle, a valve adapted to close the liquiddischarge opening from the interior, a springarm with which said valve is connected, and
a stem connected with the spring-arm and slidable through a sleeve exterior to the vessel, with a means by which it may be actuated to open or close the valve. V
3. A device for discharging liquids from containing vessels consisting of a nozzle, the lower portion of which connects directly with the interior of the vessel and the upper portion closed by a diaphragm at the inner end,
an air-passage connecting with. the nozzle through an opening in the upper part of the diaphragm and extending upwardly wlthln the containing vessel, converging to a small inlet-opening at theinner end, a valve adapted to close the liquid-discharge fixed to an elastic arm Within the vessel, a stem movable through a sleeve in the side of the vessel connected with the elastic arm having an exterior head or means by which it may be forced inwardly to open the valve, said stem passing through the air-inlet opening and having a groove or passage made transversely across 'it adapted to coincide and make a continuous passage in the air-inlet when the valve is opened and to move from the air-inlet so that the-stem closes the passage when the valve is closed. v
4. A device for discharging liquids from containing vessels consisting of a spout or nozzle, the lower half of which has an opening into the vessel and the upper part of the inner end closed by a diaphragm, an air-inlet passage extending within the vessel having its lower end connected with the spout by a hole through the upper part of the diaphragm and its upper end opening .into the vessel, an elastic arm fixed within the vessel having a valve at one end adapted to be closed against the interior of the nozzle-opening by the elasticity ot' the arm, a stem connected with the arm and slidable through a sleeve having the outer end exterior to the vessel whereby it may be pressed so as to open the valve and allow it to resume its normal position when the valve is closed, a locking-lug upon the stem slidable in a groove or channel in its incasing tube and adapted to engage with slots or inclines made in the tube so that by turning the spindle, it may be locked when the valve is closed or when it is opened.
In witness whereof I have hereunto set my hand.
