iough an ice Fink 1S Seeefieo @n sleepeis can be "7 mais ldegree than is the bed 1, and it should have better heat conducting properties than does such bed. It may comprise a granular material such as is commonly used in the production of tennis courts or sports areas. 'Ihus for example, where the rink is to be adapted for use as a tennis court when not used as an ice rink the surface layer 3 may be formed of any of the materials which are commonly used at the present time for forming hard tennis courts, amongst which there may be mentioned tine sand, more or less line brick dust, tine red colored slag or in some cases fine grained clay or earth or mixtures of these. should be suitable for sports purposes such as for sprinting or jumping when not in use as an ice rink this upper surface layer may be formed of other materials which are employed at the present time for the production of surfaces for these purposes. This material has in accordance with the invention a smaller porosity than the material` of the bed 1 in order that, when the ice rink is to -be brought into operation, water placed on the surface does not permeate this layer too quickly. On the other hand, the material must have a definite, if small, porosity for the above given thermo-technical reasons and in order to assure a flowing olf and draining of the surface layer in a comparatively small time so that the rink can be put out of operation by stopping the refrigerator machine and the surface employed as a sports area, within a relatively short time thereafter. The layer 3 can, as will be seen from the drawings, be essentially thinner (for example, 3 cm. clear above the tubes) than the bed 1.

The characteristic of the invention lies in the provision of two layers for the ice rink of which the lower one is of high waterpermeability and porosity and good heat insulating capacity while the other upper layer is essentially of smaller porosity, of good heat conductivity and can be employed as a sports surface. The cooling tube system is arranged within one or other of these two layers or partly in one layer, and partly in the other.

As the invention also contemplates the use of the upper surface for sports purposes particularly as a tennis courtl it is desirable that the upper layer should have a suitabliY good resiliency. In order to attain this and to'prevent displacement ofthe tube or pipe system the latter is, according to the invention laid upon sleepers in the same wav as railway rails are laid upon sleepers. The sleepers should be according to the invention suitably resilient, as by being made from wood, or they may be made from metal for ex'anuile iron. This further modification of the invention is illustrated in Figs. El to llore l is the bed which is prepared in the same manner as has been described with reference to Where it is desired that the rink` Fig. 1. On this bed are laid the sleepers 4.- on which the tube system 2 is disposed, and finally, the surface layer 3 is laid, whose properties have already been described with reference to Fig. 1. In this view wooden sleepers 4 are indicated.

In Fig. 4.- the disposition of the sleepers and the tube system is shown by Way of example, and here iron sleepers 4 are represented. In Figs. 4: and 5 the connection of the tube system to the refrigerator instrument is illustrated. 5 represents the entrance pipe for the cooling material for example cooled brine and 6 is the return pipe for this cooling material, 7 and 8 are controlling valves. The pipes 5 and 6 are connected in any desired way with suitable refrigerating apparatus.`

From the foregoing description and the drawings it will be understood that these embodiments are merely given by way of example of the invention and are further merely given as schematic diagrams.

The invention above described as characterized in the subsequent claims can naturally be altered in different ways and constructed somewhat differently.

I claim:

1. In an artificial ice rink, the combination of a water-permeable porous and heat insulating material formed into a bed, a cooling pipe system laid on such bed and a surface layer disposed above the cooling pipes which is formed from a granular material whose porosity, water-permeability and heat insulating capacity is essentially less than that of the bed but through which water may slowly pass to drain the upper surface.

2. In an artificial ice rink, the combination of a bed formed of slag, a cooling tube system disposed thereon and a surface layer which has less porosity, water-permeability and heat insulating capacity than that of the bed but through which water may slowly pass to drain the upper surface.

3. In an artificial ice rink, the combination of a bed formed of blast furnace slag with a superposed cooling tube system and a surface layer which is of less porosity, water-permeability and heat insulating capacity than that of the bed but through whichV water may slowly pass to drain the upper surface.

4. In an artificial ice rink, the combination of a bed formed of water-permeable, porous and heat insulating material, a superposed cooling tube system and a surface layer which is formed of a granular material whose porosity, water-permeability and heat insulating capacity is essentially less than that of the bed and is also thinner than the said bed but through which water may slowly pass to drain the upper surface.

5. In an artificial ice rink, the combination of a bed formed of water-permeable, porous and heat insulating material, a tube disposed on sleepers on said bed and a sur face layer arranged thereon which is formed from a granular material whose porosity, water-permeability and heatk insulating capacity is essentially less than that of the hed but through. which water may slowly pass to drain the u per surface.

t, In an artificial ice rink, the combinatie of a bed formed of highly water-permeable, porous and heat insulating material, a tube system disposed upon resilient sleepers on said bed and a surface layer disposed thereon formed from granular material whose :c rcsity, water-permeability and heat L. ating rcapacity 1s essentially less than that of the hed but through which water may slowly pass to drain the upper surface.

7 2 In an artificial ice rink, the combination of la bed formed of a highly water-permeable, porous and heat insulating material, a tube system disposed on resilient iron slee ers on said bed and a surface layer dispose thereon which is'formed from gra lar material whose porosity, water-permea ility and heat insulating capacity is essent ally less than that of the bed but through w ch watermay s slowly pass to drain the up r surface.

8. In an artificial ice rink, e combination of a bed formed of highly water-permeable, porous and heat insulating matenal, a tube system disposed onl wood sleepers on said bed and a surface layer disposed thereon which is formed from granular material `whose porosity, water-permeability and heat insulating capacity is essentially less than that of the bed but through which water may slowly pass to drain the u per surface.

9. In an artificial ice rin a bed composed of a lower permeable layer, a less permeable surface layer throu h which water may slowly pass and means or freezing water which may be spread over the surface layer, such means belng located in the bed in a position app'oximatmg the zone where the two layers mee r I 10'. In anarticial ice rink, a bed formed 'of a lower layer of permeable material permittng the drainage of water, a less permeable surface layer and a system of cooling coils located within the bed at the zone approximatin that where the two beds meet, the permea ility of the surface layer being such as to permit water to remain thereon for a suicient time to congeal to a solid ice surface when the cooling coils are in operation and to drain-away through such layer when the cooling coils are out of operation.
