FOAM OB FBO'IH DISSIPATOR- Specification o! Lettera Patent.
Patented Aug. 30, 1921.
Application filed August 5, 1918. Serial No. 248,333.
To all 'whom it may concer/n.
Be it known that I, OscAn OmzvALL, a citizen of the United Statesand a resident of the borough of Manhattan, in the county, city, and State of New York, have invented certain new and useful Improvements in Foam or Froth Dissipators, of which the following is a specification.
This invention relates'to devices for breaking up the froth on liquids as well as for separatin the gases from the same, and it is especia 1y available to dissipate the foam found in milk and liberate the air contained therein.
The main object of the invention is to produce a device of the nature set forth which shall efficiently perform the function of breaking up the film that usually.
surrounds the bubb in milk and separatin the released gases or air therefrom.
urther objects are to provide la device of the character described that is of simple and durable cnnstruction, and the parts of which are readily removable for purposes of inspection or cleansing as well as quickly replaced.
Other vention will become apparent cation proceeds.
With the aforesaid objects in view, the invention consists of. the novel combinations and arrangements of parts hereinafter described in their preferred embodiments, pointed out in the subjoined claims, and illustrated on the annexed drawing wherein like parts are designated by the same reference characters throughout the several v1ews.
In the said drawing f Figure I is a sectional elevation of a device constituting one. form of the present invention, some of the elements thereof being partly broken; and
Fig. II
objects and advantages of the inas the specifiis a cross sectional plan view of the same form of the device, the section being taken on the line II-II looking in the direction pointed out by the arrows in the latter figure.
Generally described, the invention comprises a tank or vessel, the bottom whereof has an inlet admitting the liquid which is to have the foam or froth and the gases or air entrained inthe same broken up and separated. Surrounding the inlet for the liquid is a primary bubble intercepter con sisting of nested perforated elements throughvwhich the fluid must flow and operating to break up most of the foam or froth bubbles. After the liquid has gone by the first intercepter it encounters a secondary bubble intercepter over which the fluid passes in a thin film. This serves to extract the most minute bubbles and release the last vestige of gases or air from the same. The degasified and frothless fluid is then drawn off. The invention also includes in its organization an air vent or escape for the liberated gases or air and a valve automatically closing the latter and thereby pre'- ventin overflow of the liquid in case it rises a normally within the vessel.
The advantages of the invention as here outlined are best realized when all of its features and instrumentalities are combined in the one and same structure, but, useful devices ma be produced embodying less than the who e.
It will be obvious to those skilled in the art to which the invention appertains, upon becoming conversant with the details thereof, that the same may be incorporated in several different constructions. The accompanying drawing, therefore, is submitted onl as showing the preferred exemplification of the invention.
In the embodiment of the device under consideration, the numeral 1 .denotes a container formed by a side wall 2, preferably cylindrical, and a bottom 3, having a flange 4 thereon to which the wall 2 is connected as by turning up the lower end 5 of the latter around the said flange 4.
Substantially at the center of the container 1, is arranfved an inlet pipe or conuit s, through wlieh the liquid to be freed from froth or foam is conducted in an upward direction.
Over the inlet 8 are placed a plurality of inverted basket-like or bell-shaped elements 9, 10 and 1l nested together. These elements are respectively provided with numerous sharp-edged perforations 12, 13 and 14 in their sides and tops. The perforations in the several elements are of varying' size, thv largest being in the innermost element 9, those next in dimension occurring in the element 10, and the smallest in the outermost element 11. y
Although the said bell or basket-like elements are shown cylindrical and provided with perforations both in the sides amd heads, as well as nesting with their lower between the two anges 39 and 40 which are clamped into tight contact therewith by bolts 42, or other suitable means.
The cover 37 preferablyat its highest point, is provided with a contracted neck or opening 45 which may be in the form of a small tube, the lower end 46 whereof, as shown, can be utilized as a seat for a valve 47, carried by a fioat 48 through the intermedia y of a stem 4,9. The latter has at its outer or top end a cap or closure 50 which ordinarily overlies the opening or neck 45 with the exception of small apertures 51 formed in the upper part of this neck for allowing the escape of the volume of gas or air separated from the liquid in the normal or ordinary use of the apparatus. It is understood that the gas or air liberated from the froth and foam which Separates from the liquid rises and collects in the upper part of the container beneath the cover 37.
The stem 49 carrying the valve 47 and cap 50 is preferably guided by wings or ribs 52 projecting inwardly from the neck 45, the gas and air of course, being free to pass between them.
In case there is. an excessive supply of liqpid to the container or the liquid for any ot er cause, rises to the top thereof, its es- Y the neck 45 will be prevented by the valve 47, which is lifted against its seat when the float 48 is buoyed up by the liquid. Consequently there will be no loss of liquid.
The operation of the device will be perfectly obvious from the foregoing description.
lVhile a certain preferred embodiment of this device has been shown and described, it will be understood that changes in the form, arrangements, proportions and details thereof may be made, without departing from the scope of the invention as defined y the appended claims.
Having described my invention what I desire to secure by Letters Patent and claim 1.
