Description of Prior Art One device known in the art comprises apparatus simulat;ng the appearance of a natural object, statuary, or like object~, the interior of which includes means for circulating a chilling medium therethrough. The apparatus proports to chill the exterior surace to any desired extent, however, in fact, the apparatus is capable of creating only a very thin layer of frost or ice crystals. It is entirely in-capable of forming a substantial layer of ice.
Also known in the art are imitation ice ornaments. One such ornament utilizes a tran~parent hollow body made of synthetic resin in place of real ice. Refrigerating means chill the surface of the hollow body only insofar as necessary to cause water vapor to condense on the outer surface, creating the illusion of melting ice. Such an apparatus is also incapable of forming a substantial layer of ice.

it being understood, howev~r, that this invention is not limited to the precise arrangements and instrumentalities shown.
Figure 1 is a side view in partial section of an apparatus for forming ice sculptures or the like according to this invention, the ice sculpture being in the form of an ice pole; and, Figure 2 is a diagramatic representation of an alternate embodiment of the apparatus shown in Figure 1, wherein the ice sculpture is in the form of a snowman.
A 3_ ~ ~ ~ 74~ ~
Detailed Description of Preferred Embodiment An apparatus 10 for forming ice sculptures or thP like according to this invention is illustra~ed in Figure 1. The apparatus 10 comprises a lower housing 12 and upper projecting member 14, on which a layer of ice may be formed. The apparatus is provided with means 16 for refrigerating member 14. The refrigerating means 16 is illustrated diagramatically, with a portion thereof being disposed in the housing 12 and a portion thereof being disposed in member 14.
Member 14 comprises a helix of stacked pipe coils 18, surrounding and supported by a central support member 20, having a hollow core 22 9 and covered by a sleeve member 24.
The pipe helix 18 is the evaporator for the refrigerating means 16, and is preferably metal, such 2S copper. The hollow central support member 20 is preferably an insulating material, such as a foam or plastic material. The sleeve member 24 is preferably a ma~erial which is highly thermally conductive, such as aluminum. It is important that sleeve member 24 be in substantial surface contact with the outer surface of the pipe helix 18.
Core 22 of support member 20 provides a conduit for the return pipe 2-5 of the pipe helix 18.
The remaining elements of refrigerating means 16 are conventional components, and are disposed in housing 12.
These components include compressor 26, expansion valve 28, a filtering and drying element 30, a liquid receiving means 32, a condensor 34, and a fan 36 for the condensor 34. The refrigerating means 16 utilizes conventional refrigerating fluids, such as freon. The direction of fluid flow of ~ ~ ~7 ~
the refrigerant is indicated by the arrows. As indicated, the refrigerant is compressed and pumped by compressor 26 through condensor 34, where it is cooled by fan 36, through expansion valve 28, up the pipe coil helix 18, down return pipe 25, through filtering and drying means 30, into the liquid receiving means 32, and back through compressor 26.
As a result of forming the evaporator of the refrigerating means in a stack of coils, and surrounding ~he stack of coils by a highly thermally conductive material in substantial sur-face contact with the stack of coils, it is possible to form a substantial layer of ice on the outer surface of the ther-mally conductive sleeve, even in environments not otherwise conducive to the formation of layers of ice, such as inside heated buildings or the like.
One of the many applications for the apparatus illustrated in Figure 1 is as an ice pole or a "North Pole" to be used by stores and shopping malls in conjunction with Christmas displays and appearances by Santa Claus. To this end, the apparatus may be provided with control means 38 and tempera-ture range control means 40. The control means 38 may be provided with a 24 hour clock timing mechanism, operated by dial 42. The temperature range control means 40 is provided with a temperature sensor 43, adjacent the output of the con-densor 34, and is controlled by dial 44, conveniently located adjacent the control dial of the 24-hour clock. The apparatus is energized through power cord 46, and protected against overload and danger from electrical shock by circuit breaking means 48.
In furtherence of the decorative application of the apparatus, it may also be provided with light means 50.
Light means 50 may, for example, be a large frosted light ~ J7 ~ ~ ~ 7g~
bulb, or an ordinary ll~ht bulb mounted in a frosted globe.
Light means S0 is mounted by means of plug 52, in the top of member 14, and is connected to control means 38 by circuit connection means 54, also passing through core 22 of central support member 20.
During the course of operation of the ice forming apparatus, frost will first appear on the outer surface of sleeve 24. After some time, successive layers of frost will form a substantial layer of ice. It is possible that some water will not be frozen, but will drip down sleeve member 24. This will certainly be the case when the apparatus is shut off. Accordingly, upper member 14 is mounted in a basin or depression 56, formed in the top of housing 12.
Basin 56 is provided with one or more drain holes 58, whi h channel the liquid water through tube 60 into removably mounted tray 62. The provision of an additional drain hole within the periphery of upper member 14 provides an outlet for any water which may condense and drip inside support member 20.
Use of the apparatus taught in this invention makes it possible to form an ice sculpture or the like in virtually any shape which can be defined by the combined structure of a stacXed coil hèlix and a corresponding thermally conductive sleeve member in substantial surface contact with the pipe helix. In some cases, it may be difficult or uneconomical to form the sleeve member in a particular shape. Therefore, some apparatus may be constructed without an outer sleeve member. Such an alternative structure is shown diagramatically in Figure 2. Figure 2 illustrates an ice sculpture in the form of a snowman. The apparatus 10' comprises a lower housing 12 and an upper projecting member, comprising stacked spherical layers 14'. The diameters of the coils of the pipe helix 18' vary in size in accordance with the desired or predetermined shape of the ice sculpture. The light means 50' may be adapted in the form of a face, wlth light ~2~
shining through the ~y~s, nose and mouth of the snowman.
The light means 50' may rest upon the top of the central support member 20', which may also be of the overall corresponding shape. In order to support the pipe coils in the lower half of each spherical layer, it may be desirable to form corresponding grooves around the outside surface of the central support ~ember, in which the coils of pipe may be disposed.
Generally speaking, the stacked pipe helix will be self-supporting in the vertical direction but may require support against lateral displacement of particular coils in the helix. As an alternative, it is also possible to form the outer sleeve 24 with grooves corresponding to the pipe helix, thereby providin~ support and guidance for the coils of the helix, without need for a central support member.
The present invention may be embodied in other specific forms without departing from the spirit or essential attributes thereof, and accordingly, reference should be made to the appended claims, rather than to the foregoing specification as indicating the scope of thé invention.
