' ILLUMINATED SKATING RINK Filed March 19, 1953 4 Sheets-Sheet 4 INVENTOR. ALPHEUS E. DICKSON A TTOPNE Y5 ILLUMINATED SKATING RINK Alpheus E. Dickson, Los Angeles, Calif., assignor to National Theatres, Inc., Los Angeles, Calif., a corporation of Delaware Application March 19, 1953, Serial No. 343,479 9 Claims. (Cl. 62-12) This invention relates to skating rinks and particularly to skating rinks for use in theatrical productions where it is desired to obtain beautiful and startling illumination effects.

Heretofore skating rinks have been illuminated from beneath the ice but such rinks have been impractical and extremely expensive and difficult to maintain.

Rinks have been provided with glass bottoms, over which water is frozen. Illumination has been supplied by light sources placed beneath the glass bottom. Such rinks have been impractical both from a construction and maintenance point of view.

Other illuminating means have been concealed in tubing and have been embedded in the surface of the rink. Rinks illuminated in this way have presented serious problems of maintenance and servicing.

The object of this invention is to obviate the difiiculties of bottom illuminated skating rinks above mentioned.

Another object is to provide a practical, easily maintained rink which is adequately illuminated from beneath the surface of the ice.

Another object is to provide such a rink in which the lighting means may be easily serviced and in which burned-out illuminating means may be easily changed.

Another object of the invention is to provide a plurality of rinks which may be arranged in novel fashion in order to provide a suitable setting for a theatrical production.

Other objects and advantages of the invention will be apparent from the following description of the invention, which is shown and described here in the preferred form which has been found to be satisfactory in actual use and which is shown by way of illustration of the invention without any intention of limiting the inevntion to the form shown.

Fig. 7 is a front elevational view of the form of invention shown in Fig. 6, and

Fig. 8 is a detailed view partly broken away of one of the rinks employed in the invention shown in Figs. 6 and 7.

The invention consists generally in providing a suitable watertight pan which is provided with suitable freezing coils for freezing water in the pan. Directly above these coils are disposed a plurality of transverse glass tubes which are embedded in the surface ice of the rink. These tubes may be closed at one end and are open at the other end which extends in Watertight relationship through one side wall of the watertight pan which holds the ice. These tubes hold the illuminating means which consists preferably of a plurality of light bulbs or tubes which are connected in parallel and which, with their connectors, are inserted into the tubes, so that they may be easily removed for servicing without interfering with the ice surface.

In Fig. 1 the rink is indicated generally at 1. It consists of a pan or waterproof container 2, which has a bottom 3 and continuous side walls 4, which are preferably copper. These walls are supported by suitable supporting beams 5 and flooring 6 and insulation 7. Disposed adjacent the bottom of the pan are the freezing coils 8 which extend transversely of the rink and are connected by suitable headers 9. The freezing solution is circulated through these coils, which are preferably embedded in a layer of sand 10, which lies substantially flush with the upper surfaces of the coil.

Disposed above and extending transversely of the coils are glass tubes 11. These lie directly on the surface of the sand, which is preferably painted with a white paint. Directly below each tube 11 is a strip 12 of aluminum foil which serves as a reflector to direct the light upwardly. The tubes 11 are frozen in the surface ice 13 adjacent the surface of the rink.

A suitable gutter 14 with drain 15 is provided to take care of overflow during filling of the rink.

The tubes 11 extend through'apertures 16 in one side wall 4 of the pan or container. Suitable sealing gaskets 17 and 18 are provided to make the joint between the Wall 4 and the tubes 11 watertight. The tubes 11 extend outwardly at one edge of the rink which is preferably the front of the stage. The ends are housed in a suitable housing 19 which has a supporting wall 20 with an aperture 21 and gasket 22. A facing member 23 closes the front of the rink or stage to conceal the ends of the tube. It is held in place by suitable bullet fasteners 24 .so it may be readily removed for servicing the illuminating means. 7

The illuminating means consists of a plurality of elongated tubes 25, such as neon tubes. These tubes, with their connectors 26 and 27, lie within the tubes 11,-and the tubes 25 are connected in parallel so that if one tube becomes inactive or burns out during a performance, the total effect on the illumination will not be particularly great.

In addition to using neon tubes of various colors, which are particularly effective and which do not generate enough heat to materially affect the surface of the ice, it is possible to use ultraviolet light-producing bulbs or black light for use in connection with actors clothed in luminescent costumes.

When it is desired to change any of the lighting or to change burned-out bulbs, it is a simple matter to remove the facing member 23 and to pull the tubes or bulbs 25 and their connectors 26 and 27 from the tubes 11. Burned-out tubes may be replaced or different tubes may be inserted for giving different lighting effects.

It will be noted that the construction above described is particularly satisfactory because the lighting elements are readily available for service. The structure is pro- 0 vided with adequate support for the weight of the pan,

the sand, the cooling coils, the lights and the actors.

In Figs. 6, 7 and 8 is illustrated a form of the invenan aea tion which has been found to be'particularly attractive for theatrical production. A plurality of individual rinks 101 are provided. They are in general of the same construction as the rink above descr'ibed-but are smaller in size and are supported by suitable legs'102-which may vary in height to give a stepped effect between rinks, as indicated in Fig. 7-. With such an arrangement, it is possible to have the center rink 101 slightly higher than the other rinksand ata higher elevation. The performersinay work up to the center rink using the other rinks as steps, and during the production all-of'the rinks may be occupied by different performers.

The above described invention is a practical and effective medium of presenting skating shows. Adequate illumination is supplied at the surface of the ice and the coils used for the freezing medium may be standard metallic coils and it is possible to use standard freezing solutions without any regard for transparency since the lighting comes from above the coils. It is easy to make sure that the entire rink is watertight and of adequate strength to support'not only the elements ofthe rink, but a large group of performers. Itis likewise easy to change lighting effects and to service the lighting medium to replace burned-out elements or those which have become inactive for various reasons.

' A preferred form of the invention has been described, although it will be clear to those skilled in the art-that other forms of the invention could be employed without departing from the spirit or essential attributes of the invention. This form of'the invention has been shown by way of illustration only and not by way of limitation.
