Another object of this invention is to provide a device of the above character in which means are provided for regulating air flow in the vicinity of the light bulb to regulate the quantity of heat applied to the chamber to produce vapor at a rate necessary to maintain the desired rate of bubble production.
The above and other objects and features of this in vention will be in part apparent and will in part be obvious to those having ordinary skill in the art to which this invention pertains, from the following description, the accompanying drawings, and the appended claims.
In the drawing, FIG- 1 is a view'in elevation of an animated display ice embodying the instant invention and simulating the appearance of a beverage stein; and
FIG. 2 is a view in vertical section taken generally along the line 22 in FIG. 1, portions of the structure being broken away to more clearly illustrate details of construction; and
FIG. 3 is an enlarged fragmental view in vertical section of a portion of the structure shown in FIG. 2.
In the drawings and following specification, like reference characters indicate like parts.
The embodiment of the invention. illustrated in the drawings simulates the appearance of a beer stein and is suitable for use as an advertising display of substantial dimensions and in which the appearance of an effervescing beverage may be produced through the use of a sealed chamber partly filled with liquid. The embodiment illustrated in the drawings with particular reference to FIG. 2 has a frame 15. The frame 15 comprises a ring portion 16, a mounting bracket portion 17, and sling portion 18. The component portions 16, 17, and 18 of frame 15 may be fabricated or joined in unitary relation by means of welds or the like.
Frame portion 15 is secured to a member 19 which is integrally mounted in fixed relation to a wall or other suitable supporting structure. Member 19 may be an element such as an electrical junction box embedded in a wall. Mounting screws 20 have threaded shanks which extend in cooperating relation to lug191 and through clearance aperture 14 provided in mounting bracket portion 17. Heads 21 of screws 20 clamp the bracket 17 against electrical junction box 19 to secure the bracket 17 and the frame 15 in fixed relation thereto with ring portion 16 disposed in a substantially horizontal attitude. A socket 40 having mounting tab 41 is secured by'nv'et' 42 to frame sling portion 18. An incandescent light bulb 43 is in cooperating relation tosocket 40 and supported in centered subjacent relation to the central aperture 161 provided in frame ring portion 16. The peripheral margin of frame ring portion 16 is turned upwardly to form a rim flange 44 which assists in location and retention of a device supported upon frame ring portion 16 in a predetermined position.
Frame ring portion 16 is adapted to support a generally cup-shaped-chamber-defining transparent envelope 22, which may be of glass or other suitable material having properties of strength and chemical inertness to the substances with which it may be expected to come in contact. The envelope 22 comprises an outer shell portion 23 and an inner shell portion 24. Outer shell portion 23 is of generally cup-shape, having a bottom 25 and an upstanding wall 26 which terminates in rim or edge 27. The inner shell 24 comprises a hollow glass vessel having an upstanding wall 28 which extends upwardly and is joined to neck portion v29 by inwardly turned portion 14. Neck portion 29 extends upwardly to an outwardly flaring mouth portion 30, the peripheral edge of which is turned upwardly to form a lip-like cylindrical rim having an edge 31. The bottom of inner shell 24 comprises a conic ring form portion 32 extending in integral relation from the lower portion of wall 28 to the upper portion of depending lip 281. Depending lip 281 is joined by curve portion 34 to the peripheral portion of vapor-collecting dome 33.
Envelope 22 is assembled by placing mat or pad 35 inside outer shell portion 23 in a position in which it covers the central portion of bottom 25. The pad 3 5 shown in the drawing is a felt-like mat of glass fibers having a density and interfiber spacing of predetermined character which will be subsequently explained. After mat 35 is placed, as shown in FIG. 2, the inner shell 24 is advanced into co-axial relationnto .andwithin cuter she'll portion 23. The thickness and density of pad 35 and the axial dimension of shell 24 are such that the curve portion 34 presents an annular rim or depending portion of a diameter approximately the diameter of bulb 43, a'nnu'larly of vapor-collecting dome 33 so as to compress pad 35 in the manner shown in FIG. 2. It will be noted as shown in FIG. 2, the central portion of mat 35 under vapor-collecting dome 33 is substantially uncompressed and is in spaced relation to the central portion of dome 33 while portion 34 is pressed into mat 35 when the edges 27- and 31 of the respective shell portions 23 and 24 are in adjacent relation suitable for fusing of the rim portions 27, 31 of said shells to join the inner and outer shells into a unitaryenvelope which encloses a cupshaped-shel-l-form chamber 38. As shown in FIG. 2, a filling neck 36 is provided as an integral portion of inner shell portion 24 and the bore 37 extending therethrough, provides communication between the free atmosphere and chamber 38.
A suitable fluid 45 such as a methylene chloride in liquid form is introduced through bore 37 into chamber 38. I have found that the quantity of methylene chloride introduced in the embodiment illustrated in the drawing may occupy a volume of the order of two-thirds of the volume of chamber 38. Thereafter, the remaining volume of chamber 38 is preferably filled substantially with methylene chloride vapor 46 and filler neck 36 is fused shut at 39 to seal envelope 22 and preclude the escape of methylene chloride from chamber 38.
When envelope 22 has been assembled, filled, and sealed, as described, it is adapted for use in display devices simulating the appearance of transparent containers of eifervescing fluids. It is to be noted that the thin shell of fluid 45-disposed between walls 26 and 28 has substantially the same appearance to an observer as would the outer envelope filled with such fluid in the absence of inner shell 24. The fact that the presence of inner shell 24 is not readily apparent in a device such as is shown in FIG. 1, is due in part to the fact that a thin opaque band 47 conceals the gas filled portion of chamber 38 and the envelope 22 defining same by reason of the fact that the lower edge 48 of the opaque band 47 extends below the upper surface 49 of the liquid in chamber 38.
As shown, suitable conductors of electrical energy wires 5051, extend from socket 40 to a source of electricity (not shown), such that incandescent light bulb 43 is illuminated by electrical energy supplied through wire conductors 5051. Such operation of lamp bulb 43 produces light and heat. Since the envelope 22 is transparent, some of the light emitted from bulb 43 passes upwardly through the envelope and illuminates the liquid contained therein.
The heat produced by bulb 43 rises upwardyy and heats the central portion of the bottom 25 of outer shell portion 23. The area heated is primarily the area overlain by mat 35 which tends to restrict fluid flow in the vicinity of the heated portion of bottom 25. When the liquid 45 contained in chamber 38 is methylene chloride, such local application of heat raises the temperature of bottom 25 to the boiling point of methylene chloride, approximately 104 Fahrenheit, and boiling or vaporization of the liquid commences. The flow of liquid methylene chloride into the heating zone is restricted by the mat 35 as Well as the previously formed methylene chloride vapor substantially filling the interfiber spaces in at least the central portion of the mat 35. A portion of such vapor rises into dome 33 displacing any liquid methylene chloride therein. As the vaporization of methylene chloride progresses in the mat 35, vapor will be forced outwardly in a generally radial direction through the interfiber spaces of pad 35 from which the vapor escapes in the form of bubbles 52, 53. These bubbles 52, 53, upon escape from met 35 move upwardly through the liquid methylene chloride .45 and interface .49 .to, the gas-filled portiqn 9f Chamber 38 designated by the reference character 38G. Condensation of methylene chloride vapor occurs in chamber portion 386 and as apparent from FIG. 2, condensate is free to drain into the liquid filled portion of chamber 38 whereby the movement of vapor upwardly through the liquid methylene chloride will eventually be at a rate in equilibrium with the rate of return of condensed methylene chloride from chamber portion 38G. It may also be noted that Where the curve portion 34 is in compressing relation to mat 35, there will be gaps or spaces through which vapor may travel between the fibers of mat 35 and the surface of inner shell portion of envelope 22. The bubbles 52 of vapor which escape through apertures or spaces between the inner shell portion 24 of envelope 22 and mat 3-5 tend to issue as streams of individual bubbles 52 while those bubbles 53 of vapor which escape by passage between the fibers of the mat spaced from the envelope tend to issue in a random fashion as bubbles'53 which do not appear to be released in stream form. The size range of bubbles 52, 53, which escape may be regulated by the density of the mat, that is, the interfiber spacing, and to some extent by the degree of heating applied to the mat-occupied region. The degree of heating affects the quantity or volume of vapor produced and thus the volume and number of vapor bubbles 52, 53 produced to rise upwardly through the liquid 45.
A cup-like shell portion 54 is provided to decoratively house the lower portion of envelope 22, frame portions 16, 18, light bulb 43, and socket 40.
To secure cup-like screen portion 54 in desired relation to the other portion of the device shown, a suitable vertical shaft motor 55, which may be of the synchronous clock type adapted to have an output shaft speed in the range of a few revolutions-per-minute, is mounted upon frame sling portion 18 in which an aperture 181 has been provided to allow downward projection of motor shaft 56. A suitable collar 57 may be secured to motor shaft, 56 by set screw 58. Collar 57 is adapted to cooperate with screen portion 54 so as to couple the latter to motor shaft 56 for rotation in unison therewith. An ornamentai retaining nut 59 in threaded relation to a portion of collar 57 prevents disengagement of screen 54 from collar 57. As shown in FIG. 2, screen 54 may be of a cuplike shape having a rim of slightly larger diameter than the frame ring portion 16 and the lower portion of envelope 22 adjacent thereto. Such dimensioning of screen 54, results in a narrow annular slot 61 through which circulating air may rise. To regulate the rate of air circulation, apertures 62 are provided in the bottom 63 of screen 54. Air may pass through apertures 62 due to heating of air within cup-screen 54 when light bulb 43, as well as motor 55, which are wired in parallel for unison operation, are in operation and produce heat. Since only a portion of the heat produced is utilized in the vaporization of liquid beneath vapor dome 33, the air moving upwardly through apertures 62 serves to carry away excess heat through slot 61 by convection.
Since conditions under which devices of the instant character must operate will vary from place to place, I prefer to provide apertures 62 of substantially maximum possible desired size and then provide regulator 65 having aperture 66 which may be shifted relative to screen bottom 63 to alter the effective area of apertures 62 and thereby effect regulation of the quantity of heat supplied to the bottom 25 of envelope 22 beneath pad 35. The even distribution and/ or dissipation of heat is enhanced by the fact that screen portion 54 is rotated by operation of motor 55.
When the device shown in the drawings is used as an attention-attracting display, advertising material v(not shown) may be placed upon various portions thereof, particularly upon the exterior surface of screen 54 which screen in such case, would preferably be of translucent character, so that light bulb 43 would also serve to backlight such indicia as may appear on screen 54.
As shown in FIGS. tans-2, the upper portions of en velope 22 are concealed by'opaque band 47. Band", which may be ofthin opaque-material applied to theexterior surface of envelope 22, .or may be an integral por-. tion of a cap-like structure 70 formed of any suitable m le terial such as die cast synthetic resins, metals, or the like. Band 47 may simulate the appearance of a collar of beer foam upon the top of the fluid simulating the appearance of effervescing beer contained in and visible through the exposed portions of the transparent walls of envelope 22. The cap portion 70 may have as an integral portion thereof a simulated hinge portion 71 and handle 72. If desired, I have found the portion 47 may be formed to snugly receive and engage the upper portion of envelope 22 and thus serve as mounting means for the portions 70, 71, 72, which, as shown, are in unitary relation thereto.
Having thus described an illustrative embodiment of the invention, it will be apparent to those having ordinary skill in the art to which this invention pertains, that various changes may be made in the embodiment of the invention without departing from either the spirit or scope thereof in view of the appended claims.
