4 Claims.

My invention is concerned with drinking vessels or glasses, and its primary object is to provide them with a self-contained source of light, the rays from which are directed into the beverage within the vessel and induce in it beautifully luminous effects, especially in colored or effervescent liquids.

To effect this purpose, I employ a drinking vessel having a beverage holder of glass or some [0 other light-transmitting material, this holder being supported upon a hollow base member.

Immediately below'the beverage holder and in the top of the base member, I place a small electric lamp, for my source of light. Within the base member are arranged a necessary electric battery and suitable means, such as a .switch, for

closing a circuit through the lamp and battery and controlling the flow of electricity.

Rays of light emitted by the lamp pass upward through the beverage holder, whose bottom thus functions, for the purposes of my invention, as a light-transmitting element or lens. Since this lens may be cast in any desired shape, it is apparent that the rays of light entering the beverage may be given any desired directive pattern and may create any one of innumerable luminous effects Thus, for use with an effervescent beverage, the lens may be so made that a bright shaft of light is sent up through the center of the beverage, brilliantly illuminating the rising bubbles of gas. On the other hand, for use with a dark red beverage, it may be so constructed that light rays are concentrated toward the outside of the beverage, and a bright-glow beneath a darker top achieved. Innumerable designs andefiects are conceivable.

My present embodiment of this invention is disclosed in Figs. 1 and 2, the latter being a sectional view along the vertical axis IIII of Fig.

1; Fig. 3 is an enlarged sectional view along the vertical axis 11-11 of Fig. 1, showing a modified form of switch; and Figs. 4, 5, 6, and 7 are plan views taken from the line IV-IV of Fig. 3, and show the modified switch from beneath. Y

5 In the embodiment disclosed in Figs. 1 and 2, a glass beverage holder I is supported upon a hollow base member 2, there being upon the bottom of beverage holder l a circular flange 3 which makes engagement with the outer surface of base memher 2. I now employ a screw connection 4 in .joining these two members, but it is apparent that many other common devices could serve equally as well. I

Base member 2 is composed of a broad circular foot 5, a relatively thin stem or shank B, and a similar connection.

flat top I. At present for this base member I use brass, which gives a light, thin, and cheap construction; yet, I contemplate the possible use of other metals, or materials such as plasticized resin, or even glass. in which latter case base 5 member 2 might be cast integrally with beverage holder I.

An electric lamp 8 is detachably supported by top 1 of base member 2, passing through an aperture in said top; Also supported by top 1 is a 10 reflector 9 which serves to direct rays of light from lamp 8 upward.

A metallic cup Ill is detachably secured to the lower portion of base member 2 by a screw or One function of cup I0 is 15 to support a battery l2, which efiect it accomplishes through an intermediate insulating cylinder H, battery l2 being thus forced tightly up against the bottom contact of lamp 8. The bottom of cup I!) is provided with an aperture l3 2( and a vertical flange M, which depends from the edges of said aperture. A non-conductive pushbutton 15, capable of easy vertical reciprocation, passes through aperture 13 and flange l4. Fixed vertically within push-button I5 is a metallic pin 2:

it, to the top of which is fixedly attached a fiat electrical contact plate l'l, which, when pushbutton l5 drops down, rests upon and makes electrical contact with the metallic bottom of cup I0. Push-button I5 is of such length that its lower 30 end projects below the lower edge 18 of base member 2, whenever plate I! makes contact with the bottom of cup Ill. Within cup ill and contacting both battery I! and-plate I1 is a spring N, which acts as an electrical conductor and 35 tends to force plate l'l down into contact with the bottom of cup l0. With the mechanism thus shown, whenever the drinking vessel is raised from a-supportingtray or table, spring l9 forces plate ll down into contact with the bottom of 45 cup I0 and creates an electrical circuit from battery l2 through lamp 8, base member 2, cup In, plate I! and spring l9. Upon the other-hand, whenever the drinking vessel is placed upon a tray or table, push-button I5 is forced upward, 45 contact between plate I1 and the bottom of cup I0 is broken, and thecircuit through lamp 8 ceases to exist.

While at present I prefer the above described switch for controlling the emission of light, it is 5G apparent that equally desirable luminous effects may be achieved through the substitution of somewhat diflerent switches. Thus, if it is desired to illuminate the beverage only while the drinking vessel is resting upon a table, I use an 65 automatic1push-button switch whose action is just the reverse of that which I have described,

or. if it is desired to make the emission of light independent of the position of the glass relative to a supporting table, a positive switch is substituted. A switch which accomplishes several of these alternatively desired results is illustrated in Figs. 3 through 7. In Fig. 3, metallic cup ID has an aperture |3 as in the embodiment illustrated in Fig. 2, but a vertical flange 38 extends upwardly from the edges of aperture I3, instead of downwardly as in Fig. 2. A non-conductive pushbutton 3|, capable of easy vertical reciprocation, passes through aperture I3 and flange 3|) and has fixed vertically within it a metallic pin 32, which extends slightly below the bottom of pushbutton 3|. A flat electrical contact plate 33 is fixedly attached to the top of metallic pin 32. Extending horizontally through non-conductive push-button 3| and securely attached to metallic pin 32 is a metallic pin 34, which acts as an electrical contact in a manner hereinafter to be described. Just .above metallic pin 34, push-button 3| is cut away slightly to form a recess 35 topped by a shoulder 36. Fixed vertically in the bottom of cup In is a small metallic pin 31, which supports and acts as a fulcrum for a rotatable metallic plate 38. Plate 38 is stepped downwardly at 39.

As shown in Figs. 4, 5, 6, and 7, metallic plate 38 is roughly in the form of a segment of a circular plane, having pin 31 as its axis. An aperture 40 in plate 38 is, with metallic pin 32, equidistant from axial pin 31 and is of sufiicient size to receive the end of metallic pin 32, but not of sufficient size to receive the lower end of nonconductive push-button 3|.

When it is desired that the drinking vessel be illuminated only when it is raised from a supporting tray or table, plate 38 is rotated to the position illustrated in Fig. 4. Push-button 3|, being entirely disconnected from plate 38, acts in the same manner as push-button l5 described in Fig. 2. When the drinking vessel is raised, spring l9 depresses push-button 3| and makes an electrical contact between plate 33 and flange 30, whereupon an electrical circuit is set up through lamp 8.

When it is desired that the drinking vessel be illuminated only when it is resting on a table or tray, plate 38 is rotated to the position illustrated in Fig. 5, the edge of plate 38 entering recess 35 in push-button 3|. When the drinking vessel is resting upona table, push-button 3| is forced upward until contact is made between horizontal pin 34 and plate 38, whereupon an electrical circuit is set up through lamp 8. On the other hand, when the drinking vessel is raised from the table, spring l9 forces plate 33 downwardly, breaking the contact between pin 34 and plate 38. Pushbutton 3| descends only until shoulder 38 comes to rest upon the top of plate 38; and it remains in this non-circuit forming position.

When it is desired that the drinking vessel be illuminated none of the time, plate 33 is rotated to the position shown in Fig. 6. The lower end of metallic pin 32 falls within aperture 39, and non-conductive push-button 3| comes to rest upon plate 38 in such position that no electrical circuit can exist, plate 33 being maintained above flange 3|).

When it is desired that the drinking vesssel be constantly illuminated, plate 38 is rotated to the position shown in Fig. 7, so that pin 32 rests upon the upper' side of plate 38, which position effects a circuit through lamp 8.

Returning to a more detailed description of beverage holder I have stated above that its bottom is cast with a circular flange 3, for purposes of joinder with base member 2. The outer surface 24 of flange 3 is preferably frosted to hinder the emission of any light from this area and also to conceal the mechanism contained within. The bottom portion of holder l which is surrounded by circular flange 3 (or roughly that lying between lines 28 and 2|), constitutes, for the purposes of my invention, a lens 22 which transmits into the beverage light emitted by lamp 8. As before stated, lens 2| may be cast in any one of innumerable shapes in accordance with the known physical laws of lenses. Through an application of these laws, any desired pattern of light rays may be directed into the beverage and any desired luminous effect achieved. Thus, in some drinking vessels, I so construct lens 22 that numerous rays of light are bent toward the vertical axis of beverage holder and a brilliant shaft of light rises through the center of the beverage. In others, lens 22 concentrates most of the rays of light toward the outer portions of the beverage. evenly distributed. Moreover, the side walls of beverage holder I may be cast in numerous forms and shapes, to concentrate or reflect light and to help create desirable luminous effects.

In this embodiment, it is noteworthy that the electrical circuit is positively insulated from the beverage; there-is no direct contact between them, and any liquid which spills over the edge of beverage holder I can not pass beyond a drip flange 23 formed near the bottom of beverage holder Also beverage holder is detachably supported by base member 2, an arrangement of some advantage, since it permits easy removal of beverage holder for washing and the immediate use or base member 2 with another beverage holder, thus reducing the requisite number of base members.

According to the provisions of the patent statutes, I have explained the principle and construction of my invention, and have illustrated and described what I now consider to represent its best embodiment. However, I desire to have it understood that, within the scope of the appended claims, the invention may be practiced otherwise than as specifically illustrated and described.
