Description:

My invention relates to improvements in tap handles for beer tap valves and is an improvement on the type of tap valve handle shown in Patent No. 2,046,325 for Liquid dispensing device issued to me July 7, 1936.

Unquestionably a perfectly spherical tap handle is the most convenient shape for a beverage dispenser or barkeeper to use in dispensing beer or other beverage from a bar or counter. I have shown in said patent heretofore referred to how to incorporate an advertising sign in said tap handle without detracting seriously from said perfectly spherical shape and in such a manner that the advertising plate or member incorporated therein will not cut the barkeeper's or other beverage dispenser's hand.

The present invention relates to improvements on the device shown in said application by providing an advertising sign which will tend to fill out said sphere and in my preferred embodiment substantially complete the sphere for ease of operation by the barkeeper or other beverage dispenser and, one in which the advertising, characters or insignia therein may be readily observable from in front of substantially the entire length of the bar. For this purpose I provide a transparent sign member having a convex outer surface and a rear surface having the edge on the rearmost portion thereof, said rear surface having depressions of the shape of advertising insignia extending forwardly therein and coatings of coloring matter applied to the bottoms of said depressions defining said insignia. I have found that if the outer surface of such a member be made convex, particularly spherically convex, that when the sign is viewed from in front, the said advertising insignia characters are readable through the front face of the transparent member and appear refracted from' substantially the outer convex surface of said transparent member in the same degree of convexity as said outer surface, so that substantially all of said indicia may be observed when viewed from substantially any direction in front of said base, more particularly if said outer convex surface be spherically convex. I have found in practice that such signs can be read at angles approaching 90* from the perpendicular to the plane of said member, thus increasing largely the visibility of such signs and the impression they make on anyone viewing them. The outer convex surface appears to refract the light rays in a greater degree than if a plane outer surface be employed, which refraction may be increased by concaving the inner surface of said transparent member. The ideal type of such a member is the meniscus concavoconvex lens with both the concave rear and the convex front surfaces being spherical when the angle of refraction and stereoptic effect may be increased and regulated in the desired degree, although it is obvious that any suitable type of outer convex surface may be employed and any suitable type of plane or cancave inner surface may be employed.

A further feature of my invention resides in the fact that the depressions are preferably provided with certain parallel side walls thereof inclined in substantially a single direction and a supplemental coating of coloring matter of a different shade is applied to said inclined walls so that when the device is viewed from in front, said differently shaded side walls may provide a perspective shading effect.

I have also discovered that good results can be obtained if the transparent member hitherto described is mounted on an opaque surface of the base and I have also discovered that pleasing effects involving substantially the same degrees of refraction to produce the illusion of convexedly transparent images on the outer surface of the transparent member may be produced if the transparent member is mounted on a translucent light diffusing surface on said base and a light source is mounted in rear of said light diffusing surface. I preferably employ a similar type of 'handle member as shown in my prior patent aforesaid having a neck for mounting on the tap valve operating means and a partially spherical gripping portion or base having a flat portion at the front thereof, preferably inclined upwardly from the vertical, of the general type shown in my aforesaid patent and I mount my improved transparent sign member on said flat portion in a suitable manner, and preferably provide an outer surface on said transparent member of similar spherical convexity to that of said gripping portion to substantially complete said sphere for ease of operation by the barkeeper or other 45 beverage dispenser, for this purpose, the transparent member being circular and preferably coinciding with the circular plane surface formed by said flat portion on said gripping portion.

The improved transparent member may be mounted in place of the plate shown in said prior patent in similar fashion thereto, but as said transparent member has in any'event, an outer convex surface, it will tend to fill out said sphere and an opaque reflecting surface may be either provided on said flat portion or between said fiat portion and transparent member as shown.

A further feature of my invention is to provide a device in which light may be refracted outwardly through a light diffusing surface on said gripping member comprising said fiat portion to provide a more startling advertising effect by a lighted tap handle. It is apparent that if the tap handle be made hollow it provides an ideal shaped mounting member for said light behind said light diffusing flat surface and if desired the interior of the partially spherical gripping portion may be silvered to provide in addition a concave reflector for the light source.

These and such other objects of my invention as may hereinafter appear will be best understood from a description of the accompanying drawings, which illustrate two embodiments thereof.

In the drawings, Fig. 1 is a front elevation of an illuminated tap handle constructed in accordance with my Invention.

Fig. 2 is a side elevation thereof.

Fig. 3 is a vertical sectional view thereof, with a portion only of the gripping member being shown in elevation.

Fig. 4 is a rear elevational view of the transparent member of my invention provided with a translucent light diffusing surface attached thereto and broken away for the purpose of illustrating the depressions extending forwardly in said transparent member from the rear surface thereof.

Fig. 5 is a cross sectional view of said transparent member taken along the line 5-5 of Fig. 4.

Fig. 6 is a perspective view of an alternative embodiment of my invention employing an opaque background on the flat portion of the gripping member on which the transparent member is mounted and with the outer surface of the transparent member of less convexity than to substantially complete said sphere.

ig. 7 is a cross sectional view of the transparent member employed in the embodiment shown in Fig. 6.

In the drawings, wherein like characters of reference indicate like parts throughout, 10 and 18' generally indicate embodiments of tap handles constructed in accordance with my invention.

In the descrilition when referring to the parts of the embodiment shown in Figs. 1-5, I will employ unprimed reference characters and when referring to similar parts in the embodiment shown in Figs. 6 and 7 I will employ primed reference characters.

The tap valve handle 10 or 10', in both embodiments includes, a seat 15 or 15' having a preferably integral hollow neck portion 8 or 8' projecting upwardly therefrom for mounting on the tap valve operating means as shown in my said prior patent. I employ a partially spherical base or gripping and display portion 12 or 12', preferably integrally mounted on said neck 8 or 8'. The seat 15 or 15' is preferably provided with the central bolt receiving socket projecting upwardly therein for screwing on a bolt projecting from the tap valve operating means as shown in said patent. The partially spherical gripping and display portion 12 or 12' is preferably integral with said neck 8 or 8' and includes an at least hemi-spherical portion I I or I' on the rear thereof for operative gripping in the palm of the hand or by the fingers and having the flat portion 13 or 13' at the front thereof, preferably tilted upwardly relative to the vertical as shown in said patent and being of substantially circular shape, In the embodiment shown in Figs. 1-5, said flat portion I3 may be provided with a translucent light diffusing surface 14, or with the opaque light diffusing surface 14' as shown in Figs. 6 and 7.

My invention includes a transparent member IS or 16' for use in advertising signs having a convex outer surface It or 18' and a rear surface 20 or 20' having the edge 22 or 22' thereof on the rearmost portion thereof. Said rear surface 20 or 28' is provided with the depressions 24 or 24' of the shape of advertising insignia 28 or 28' extending forwardly therein and a coating 26 or 26' of coloring matter applied to the bottoms of said depressions defining said insignia. Said transparent member 16 or 16' may be made of any suitable transparent material such as glass, transparent resin, Lucite, etc.

A main feature of my invention comprises this transparent sign member 16 or 16' having a convex outer surface 18 or II' and a rear surface 20 or 20' having the edge 22 or-22' thereof on the rearmost portion thereof, with said rear surface provided with said depressions 24 or 24' and the coatings 26 or 26' of coloring matter applied to the bottoms of said depressions defining said insignia. I have discovered that If said outer surface of the transparent member be made of a convex shape, that when the -transparent member 16 or 16' is viewed from in front, said advertising insignia provided by the coatings 26 or 26' of coloring matter at the bottoms of said depressions 24 or 24' will appear refracted as the advertising insignia 28 or 28' with a convex curvature similar in convexity to that of the convex outer surface 18 or 18' from substantially the outer convex surface IS or 18' of said transparent member 16 or IS' so that substantially all of said advertising indicia may be observable when viewed from substantially any direction in front of said base as shown in Figs. 2 and 6. The coating 26 or 26' may consist of any suitable type of paint, lacquer, or other coloring matter suitably colored by pigment or otherwise.

The rear surface 20 or 20' of said transparent member 16 or 16' may be plane as the rear surface 20 of the embodiment shown in Figs. 1-5.

I have discovered that by making the outer surface convex that the angle of refraction is increased to make the advertising matter or indicia 28 or 28' appear refracted from the outer convex surface 18 or IS'. The angle or refraction, however, of the light rays and hence stereoptic effect may be further increased if the rear surface 28' is concaved in addition, as in the embodiment shown in Figs. 6 and 7.

In the preferred embodiments shown, the outer surface 18 or 18' is preferably spherically convexed In both embodiments to provide a solid spherical sector of the type commonly known as a lens, although my invention may be employed on lenses, other than of true solid spherical sector shape. In the embodiment shown in Figs. 6 and 7 the rear surface 20' also comprises a partially spherical concavity, preferably with a different degree of curvature from that of the outer surface 18', the relative degrees of curvature and hence convexity and concavity of the respective surfaces 18' and 20' varying the refractory power 7" and hence stereoptic effect of the transparent member 18 or 16'. The transparent member 18 or 16' is preferably mounted in any suitable manner on the base 12 or 12'. In the embodiment shown in Figs. 6 and 7, the base 12' is provided with an opaque portion 14' over and to which the transparent member is suitably mounted. In the embodiment shown in Figs. 1-5, the transparent member 16 mounted over a suitable translucent light diffusing surface 14 andi an electric light bulb, or other suitable light source 30 is mounted in rear of said translucent light diffusing surface 14 to provide a source of light 30 behind the transparent member 16 to artificially light the said transparent member 16 to cause it to attract more attention. In this embodiment, the interior of the base or gripping portion 12 is preferably hollow as shown and the light source 30 comprises an electric light bulb suitably mounted in the hollow interior 13 of said gripping portion 12, and in order that the light source itself may not be reflected and refracted through the transparent member 16 the translucent light diffusing surface 14 is interposed between said light source 30-and said transparent member 16. The interior of the hollow partially spherical portion may be suitably silvered, or otherwise mirrored as at 34 to provide a concave reflecting surface to reflect and converge the rays thereof through said light diffusing surface 14 and through said transparent member 16, for this purpose the light source 30 being mounted on a suitable base in said neck 8 and suitably lighted from a suitable source of electricity by power provided through the wires 38 projecting downwardly through said neck 8 and out through said seat 15. In both embodiments the circular edge of the transparent member preferably coincides with the circular edge of the flat portion 14 of said base or gripping portion 12 so as to tend to fill out a perfect sphere and in the embodiment shown in Figs. 1-5 the outer convex surface 18 of the transparent member is of the same degree of spherical convexity as that of the gripping portion I to substantially complete the sphere. I have attained good results, however, as in the embodiment shown in Figs. 6 and 7 if the outer surface 18' of the transparent member 16' employed therein is of less convexity than that of the gripping portion II', being only of sufficient convexity to make the refracted illusion of the advertising indicia observable from up and down the length of the bar as shown in Fig. 6.

My invention provides satisfactory qualities, even if the light source and translucent light diffusing portion 14 be omitted and the translucent portion be replaced by a suitable opaque reflecting background 14', the advertising insignia being readily observable in convex shape as appearing from the outer convex surface 18' of said transparent member, as shown in Fig. 6, the outside light reflected by said opaque surface 14' and refracted through said transparent member 16', being sufficient to bring out the advertising insignia 28' in the desired fashion, when observed from in front of substantially the entire length of the bar as illustrated in Figs. 2 and 6.

As stated, however, in the embodiment shown in Figs. 1-5, I produce substantially the same effect with an additional source of light behind it and the advertising effect is somewhat more startling.

A further feature of my invention comprises the increasing of the perspective effect produced by the advertising letters or insignia provided by the depressions 24 or 24' and the coloring matter 26 or 26' on the bottoms thereof. If the walls 40 or 40' of said depressions are not painted they may refract a silvery sheen to the edges of the advertising insignia.

I may, however, in accordance with my invention provide certain parallel side walls 42 or 42' of said depressions inclined in substantially a single direction and if coatings of coloring matter 44 or 44' of a different shade from that of the coatings of coloring matter 26 or 26' in the bottoms of said depressions be applied to said inclined side walls 42 or 42', said differently shaded inclined side walls of said advertising insignia in said depressions 24 or 24' will thus provide a perspective shading effect increasing the perspective effect and reality of the illusion of making said advertising insignia appear refracted from substantially the outer convex surface of said transparent member and provided, when so refracted, with an exaggerated perspective effect of depth as shown in Figs. 2 and 6.

For ease of mounting the transparent member 16 or 16' over the flat portion 14 or 14' of said gripping portion 12 or 12' it may be provided with the spring ring 50 or 50'. The transparent member 16 or 16' or the spring ring 50 or 50' may be mounted over the flat portion 14 or 14' as shown in said prior patent, or in any suitable manner. If the spring ring 50' be omitted, the flat opaque light reflecting surface 14' may comprise an integral surface of said gripping portion 12' or the surface 14' of a separate member such as an opaque light reflecting plate of similar configuration and similarly attached to said gripping portion as said transparent plate 14 is attached to said gripping portion 12.

It is apparent therefore that I have provided a novel type of tap handle constructed to display advertising matter in a startling and novel fashion to have it observable from in front of substantially the entire length of the bar or other dispensing counter with the advantages explained above.
