LIQUID DISPENSING AND COMPOUNDING DEVIC Julian o. Barreda and Harold J. McLaughlin,
New York, N. Y.
Application March 26,
- This invention relates to liquid dispensing devices, and especially to a combined liquiddispensing and compounding device, the same being shown but not claimed in our co-pending application No. '711,934, filed February 19th, 1934.
It is well known that what is usually marketed under the name Milk, is in reality a compound or mixture of milk and cream; that the latter is lighter, or has less specific gravity, than milk; and that the cream soon rises to the top when the liquids are left for a while undisturbed; so, if the liquid-contents of the container are drawn through a faucet or outlet in absence of a compounding or mixing device, the heavier liquid will be drawn first, and afterwards the lighter will be drawn; the same being true with certain liquids besides milk and cream.
Therefore, one object of this invention is to provide a very efiective and practical means for compounding the liquids simultaneously with the drawing or dispensing of the same, and without the employment of stirring apparatus and power for operating the latter.
Another object of this invention is to provide the compounding member in such position and of such form that air (entering to take place of the dispensed liquids) rises through the body of liquids at numerous points near the bottom of the body of liquids, thereby agitating the liquids and tending to cause them to blend with one another while being dispensed.
Other objects and important features are pointed out or implied in the following details of description, in connection with the accompanying drawing in which:
Fig. 1 is a view partly in elevation and partly in vertical section, illustrating the invention applied in an inverted milk-can which constitutes the liquid container and has a part of one side broken out to show the compounding tube in one of its forms, the upper part of the compounding tube being in full elevation, while its lower part is in central vertical section.
Fig. 2 is a detail view in central vertical section, showing a modified form of the compounding tube.
Fig. 3 is an elevation of the compounding tube or tubular member shown in Fig. 2, but viewed from the right-hand side of Fig. 2.
Referring to the drawing in detail, wherein the reference numerals applied to the several parts are respectively referred toby similar reference numerals in the specification, the invention is described as follows:
A liquid receptacle or container 5, as in my cc- 1934, Serial No. 717,450 (01. 2Z167) pending application, is here shown in the form of an inverted milk-can having its cover '6 seated on a support 7 having an opening through which a dispensing spout 8 extends. In the partition 9, which forms the bottom of the container 5 and 5 the upper wall of a measuring compartment, an opening is provided. A compounding tubular member 11 or 11a is open at bothends and has its lower end secured to the wall 9 in the relation shown, or in such relation that it provides an outlet from the container into the measuring rejceptacle, while being secured to every point of the margin of the opening 10 so no fluid or liquid can pass through said opening except that which passes through the lower end of the member 11 01' 11a.
The lower end of the compounding tube or member is formed with a valve-seat 12 in which a valve closure 13 operates to open and close the outlet.
In the form of compounding member shown in Fig. 1, a seamless or true tube is provided with two graduated series of holes 14 and 14, each series being similar to the other in that the smallest hole is at the bottom, and the largest at the top, while the intermediate holes are successively larger and larger from the bottom to the top. The holes of one series are staggered in relation to those of the other series, and the spaces or distances between the holes of each series are such that the holes of one series substantially overlap the holes of the other series, as is seen in the upper part of Fig. 1. By this arrangement, the liquid at the surface can flow through a,hole of one series or the other at all levels of said surface in the container; so these two series of holes constitute, in effect, a substantially continuous inlet of the tube 11, such inlet extending substantially from top to bottom of the tube. It is desired that these holes also serve as air-inlets for the container, and to this end, the tube (11 or 11a) is inclined from its lower end to its upper end, and the holes are in the upper-inclined side of the tube 11, so as the air enters through the lower end of the tube (to replace the dispensed milk or liquid), it tends to rise perpendicularly, and thus passes out of the holes that constitute the inlet for the liquid. From the holes 14 and 14a, the air rises through the body of the liquid in the container, and agitates the cream (on the surface) so it will flow more readily toward and into the compounding tube.
Instead of making the compounding member out of a tube, it may be formed of a blank of sheet metal so that its longer edges 11b are slightly spaced from one another (as shown in Fig. 2) to provide an inlet or slot 110 that extends substantially from top to bottom of this tube-like or substantially tubular member 11a whose bottom and top are actually tubular, the top of the slotted part being expanded by a ring 11d, while its bottom is a ring lle, these rings soldered or otherwise secured to the intermediate main slotted part that includes the edges 11b. The upper part of the slot 110 is wider than the lower part, to compensate for the difference in pressure at the top and bottom of the liquid, and to compensate for the comparative thickness and immobility of the cream to that of the milk.
It is quite within the scope of this invention to substitute a single row of holes 14 or 14a for the two rows, and to locate the same where the slot 110 is shown; also quite within the scope of the invention to cut the slot lie in a tube that includes the part lie and eliminates the ring 11d; so it is seen that the invention is not limited to the precise structure and arrangement shown; for the invention is susceptible of numerous changes within the scope of the inventive ideas as implied and claimed.
What we claim as our invention is:
1. In a dispensing and compounding device, the combination of a container for holding and dispensing liquids o! difierent specific gravities, said container having an opening in its lower end, a tubular member having an open lower end fitting against all points of the margin of said opening while providing an outlet through the latter, said tubular member extending substantially to the upper end of said container and having a substantially continuous inlet that extends substantially from its upper end to its lower end, whereby said tubular member receives and dispenses the liquids of different specific gravities simultaneously.
2. The combination defined by claim 1, said tubular member being inclined from a vertical plane that extends up from the center of said outlet, the said substantially continuous inlet being disposed in the side of the tubular member next to said vertical plane.
3. The combination defined by claim 1, said tubular member being inclined and having an imperforate lower-inclined side and an upper-inclined side in which said inlet is disposed.
4. The combination defined by claim 1, said substantially continuous inlet being wider at its top than at its bottom and graduated in width from top to bottom, for the purposes specified.
5. The combination defined by claim 1, said tubular member being inclined from its top to its bottom and having an imperforate lower-inclined side and an upper-inclined side in which said inlet is disposed, said substantially continuous inlet being relatively wide at its top and gradually decreasing in width from top to bottom.
