Patented May 19, 1942 LIQUID DISPENSING APPARATUS Emil Schwarzkopf, Chicago, Ill. Application September 11, 1941, Serial No. 410,467
In my prior application, Serial No. 386,435, entitled Liquid dispensing devices, filed April 2, 1941, I have disclosed an attachment fora bottle or other container, adapted to permitliquid to be drawn from the container and air to be admitted to replace the liquid that is dispensed.
The present invention, relates to devices of that general type and may be said to have for its object to improve the construction and operation of the same.
The construction illustrated in application is such that there is a he aforesaid onsiderable length of spout or nozzle between thedischarge outlet and the valve inlet to the same igom with- Accordingly, after the valve is closed and all of the liquid has apparently been drained from the spout or nozzle, there may still remain in the interior of the latter a small quantity of liquid which subsequently results in dripping. Such dripping, even if it beonly a drop or two, may be objectionable if it falls upon a counter. or other support for a container from which i the liquid is being dispensed. Also, where the liquid that is being dispensed consists of wine, for example, suflicient residue may remain in the nozzle or spout, at the outlet from the latter, to attract fiies, which may place the device in an unsanitary condition.
The present invention may be said to have for its object to overcome the unsatisfactory characteristics of the dispensing device, just described.
In carrying out my invention, I make the effective length of the spout or nozzle very short,
thereby reducing to a minimum the quantity of liquid that may be so slow in being discharged that the ordinar user fails to wait until the last drop has left the spout or nozzle. Furthermore, I provide a little drip pan which automatically closes with the shutting off of the flow of liquid to the spout or nozzle, and which automatically opens in time to be out of the way of liquid fiowing down through the spout or nozzle, at the beginning of a dispensing operation.
The various features of novelty whereby my invention is characterized will hereinafter be pointed out with particularity in the claims; but, for a full understanding of my invention and of its objects and advantages, reference may be had to the following detailed description taken in connection with the accompanying drawing, wherein:
Figure l-is an elevational view of a bottle having one of my improved dispensers applied thereneck end of the bottle and the dispenser, on a much larger scale, taken on a plane at right angles to) the plane of \Fig. 1; and Fig. 3 is a view similar to Fig. 2, showing only a fragment of the lower end of the dispenser with the parts in dispensing positions, whereas in Fig. 2 the parts are in bottle-sealing positions.
Referring to the drawing, l represents a cap adapted to be screwed upon or otherwise fastened to the neck A of a bottle, or the like. The cap has a long sleeve-like central projection 2. The wall of the cap at the inner end of the sleeve 2 is provided with a series of holes or passages 3 through which liquid may flow from the bottle when the latter is inverted. Screwed upon the free end of the sleeve is a cap 4 the end wall of which is in the form of an annular part or ring which only partially closes the end of the sleeve. Extending through and slidable inthe ring-like wall of the cap 4 is what may be termed a long, cup-shaped cylindrical shell 5 open at its lower end and closed end. This shell is provided with a series of holes or ports 6 through the cylindricalwall thereof and with any desired number of air passages 1 extending lengthwise through the same in the interior of the annular wall. Screwed upon the upper end of the shell is a cup-shaped element 8 which'forms with the top of the shell a little the lower end of the spring resting on the member 8 and the upper end engaging with the body portion of the cap I. This spring is under an initial compression so that it tends constantly to force the, unit, comprising the parts 5, 8 and 9, down until the edge around the open end of the inverted cup-shaped member 8 rests on apacking ring ll overlying the annular flange portion [2 of the member 4. The parts are soproportioned that when the slidable unit is in its lowermost position, as in Fig. 2, the ports 6 'lie' below the upper surface of the flange l2, so that the packing ring II and the member 8 serve as a valve which completely out 0 communication between the interior of the sleeve 2 and the ports 6.
The slidable unit is adapted to be moved inat its upper wardly or upwardly by means of. a receptacle pressed upwardly against a pair of suitable cross arms l4 forming part of or rigidly attached to a cylindrical slide l5 surrounding the lower or outer end of the sleeve 2 and its cap 4. The member l5 has therein a plurality of elongated vertical slots l6. Screws I'I extend loosely through these slots and into the thickened lower or ring-like end or head portion of the member 4. The part l5 has at its lower or outer end a partial head comprising a thickened ring-like section l8 that has a slidable fit on the lower end of the shell 5. When the member I5 is moved up from the position shown in Fig. 2, it lifts the slidable dispensing unit that is normally held down by a spring l0.
Underlying the lower end of the ring-like part 18 of the slidable actuator I5 is a drip pan l9 which is connected to ears 20, depending from the part l8, by a horizontal hinge pin 2|; the parts being so proportioned that when the drip pan is swung through an angle of ninety degrees from its closed position, it lies well to one side of the mouth or outlet opening from the shelllike spout or nozzle 5, thereby avoiding any contact with liquid that is flowing out of the latter.
A suitable spring 22, carried by the device, acts constantly to hold the drip pan firmly in its raised, working position, in contact with the under face of the part l8 on the slide l5.
In order to be able to get the drip pan away before liquid begins to flow from the spout or nozzle, I provide a lost motion between the actuator l5 and the spout or nozzle, during which the drip pan is shifted into its idle position. The immediate means for shifting the drip pan against the resistance of its spring comprises a lug 24 projecting radially from the lower end of the shell 5 and an internal lug 25 on the drip pan immediately underlying the lug 24 at times when the drip pan is serving as a closure for the mouth of the spout. These lugs are arranged in a radial plane at right angles to and intersecting the hinge pin 2|. In order that the lug 24 will always be properly located, it is caused to project into a vertical groove 26 in the ring-like part l8; this groove serving both as a locating device and as a guide during the relative vertical sliding movements between the members 5 and I5.
Therefore, when the slide I5 is moved up, the shell 5 being still held in its down position by the spring ID, the lug 25 strikes the lug 24 and, the latter being stationary, the lug 25, and therefore the drip pan, must yield; the drip pan swinging around its hinge pin as the latter is carried up with the actuator.
Not only must there be a lost motion between the actuator l5 and the shell 5, but the actuator is preferably yieldingly held in its down position except during the act of dispensing. In the arrangement shown, the shell 5 is provided with an external annular flange 21 that lies at some distance above the ring-like head of the cylindrical actuating member l5. Between this flange and the part I8 is a light coil spring 28 which surrounds the shell; this spring being considerably weaker than the spring In so that it must first be closed to bring its coils in contact with each other when the actuator is' moved up, before the spring can be caused to yield and permit the slidable dispensing unit to be raised bodily. The parts are preferably so proportioned that when the slidable dispensing unit is moved up to admit liquid to flow out through the same, such movement is arrested at the proper point through the engagement of a cushioning ring 29, lying upon the flange 21, with the under side of the stationary flange l2.
As previously stated, the air pipe 9 extends into the vicinity of the bottom of the bottle, where it is provided with a check valve 30 that is opened through engagement with the bottom wall of the bottle when the elements are in their dispensing positions.
It will be seen that if the bottle, with one of my improved apparatuses attached thereto, is held in an inverted position, the check valve in the air pipe is closed because it stands clear of the bottom wall of the bottle. Also, the valve for controlling the flow of liquid is closed. as indicated in Fig. 2, and the drip pan is up. The distance between the ports 6 in the shell 5 and the discharge end of the shell isvery short, so that after the flow of liquid has been shut off, following an operation of the dispensing device to deliver liquid into an extraneous receptacle, the spout or nozzle quickly drains itself. However, should a very small quantity of liquid remain after the receptacle is removed, this is prevented from leaving the dispenser as it will be caught by the drip pan. Thus, the surface on which the container for the liquid is supported is protected against drippings. Not only that, but the end of the spout or nozzle, including both the air inlets and the liquid outlet, is effectively covered and shielded against contact with insects or dirt, thereby avoiding condemnation of liquid, subsequently dispensed.
It will be seen that normally the bottle or other container is sealed and communication with the outside atmosphere is prevented, whether the bottle be in an. upright or any other position. With the container inverted, as shown. a glass may be filled with wine, for example, by simply placing it underneath the cross arms and pushing it up. It will be seen that the cross arms are L-shaped, so that their horizontal elements lie at a considerable distance below the outlet end of the spout. This distance is great enough to permit the cover or drip catcher to swing open without coming in contact with the glass. At the end of this preliminary movement, the hinge ear 3| which is an integral part of or rigidly fixed to the drip pan or catcher lies in engagement with the end edge face of the lug 24; thus causing the drip pan or catcher to be locked in its idle position. As the actuator I5 continues its upward movement, it and the slidable dispensing unit move together until the ports 8 rise above the valve seat on the flange l2 as in Fig. 3; thus permitting wine to flow through the port 6 and out of the spout into the glass. As is the case with the device disclosed in my prior application, the check valve 30 in the air pipe is opened through engagement of the stem thereof with the bottom of the bottle so that air may enter above theliquid in the bottle rapidly enough to permit a,
free, full flow of liquid from the spout or nozzle. When the glass is again lowered, thefnarts are restored to the positions illustrated inFig. 2
through movements that are the reverse of those previously made in bringing about a flow of liquid. Since the drip pan is as largein diameter as is the lower end of the sliding actuator l5, it does not actually come into contact with the spout which is much smaller in diameter.
derstood that although there is very little likelihood of liquid entering the air passage, any liquid which should happen to do so would be caught by the drip pan in the same way as any drippings from the spout proper.
