3 Claims. 1

This invention relates to appliances for cooling liquids in automatic refrigerators and more particularly has ,for its object an appliance somewhat in the nature of an ice cube tray which can be used for quickly cooling liquids within or outside of the refrigerator.

A particular object of the invention is the adaptation of the ordinary ice cube tray well known in automatic refrigerators, so that it can be used for cooling liquids for beverage or other purposes without diluting the contents of such liquids.

It is well known that in using ice cubes for cooling'liquids, the melted ice cube naturally dilutes such liquids in considerable degree, especially in the case of carbonated beverages. A particular object of this invention is to provide a ready means to cool liquids without adding ice to the same.

Further objects of the invention will be apparent from the specification and the drawings, in

which Fig. 1 is a top plan view of my improved" appliance showing the tray and cover therefor.

Fig. 2 is a sectional view taken along the line 22 of Fig. 1.

Fig. 3 is a partial sectional view of the ice cube separator.

Fig. 4 is a sectional view of the cover along the line 2-2 but; with a detachable cover thereon, the tray and the ice cube separator being not shown.

Fig. 5 is a plan view of an ice tray itself with I the cover not shown.

Fig. 6 is an enlarged partial perspective view of the spout attached to the'trough in the cover in position with the tray.

III is the ice tray itself which in form is similar to the well known tray used for freezing ice cubes.

I l are the separators which in this case are.

concave at their tops since a portion of the chain i2 is cut out to provide for the insertions oi the cover It hereinafter described. The cover it has grooves or troughs it formed therein preferably integrally therewith, the series of troughs beginning with the inlet member is and ending with the outlet spout l'l. a

It should be noted from an examination of Fig. 2 that any liquid poured into the opening l6 will descend by gravity through the series of troughs to the spout I! where it will be discharged into an open container. The bottoms of the troughs contact the. cut-out portions of the separators and since the covers and the separators them- 2 liquid poured into the troughs will be immediately cooled by contact with the cover through the contact of the troughs with the concave por-- tion of the separators.

Also provided in the cover are the raised portions or convexities [8. Further provided in the cover is a plug I 9 by which the water for the tray itself is introduced. It should be noted that the cover itself may be hermetically fastened to the 10 tray as shown at in Fig. 2.

The raised portions I8 are used to provide a pocket for the air in the tray it being understood that the tray itself will not be completely flllle'd with water, sufllcient allowance being made to 15 allow for the natural expansion of the water when frozen into ice.

In the particular embodiment shown herein a rectangular tray of greater length than width is shown. but in other forms of trays, as in a square 2 tray, the grooves may be shown spirally with the delivery spout in the center and the exit spout at the side of the tray.

Where it is desired to cool carbonated beverages and to provide against escape of the carbonation, a snap-on cover 22 (Fig. 4) may be applied to the grooved top 01' the tray, the said cover being provided with a gasket 23 to render same airtight. This type of. cover would be removable so that the top of the tray at all times is readily cleanable.

As shown in Fig. 5, the tray I0 is provided with a cut-out portion 2| in the rear wall thereof to receive the spout H.

The spout I1 is firmly secured to the trough. I5

by spot welding or in any other suitable manselves are made 01 a metal with excellent heat conductivity properties, it will be seen that the ice tray having a metallic heat conducting elener. The spout l 1 being integral with the cover, the entire cover and trough I1 is hermetically sealed to the tray.

It will be seen that I have provided here an appliance in which milk, water, coflee or any other beverage can be readily cooled without diluting the contents. Further modifications will be apparent in the construction of this particular device without departing from the spirit thereof.

The grid shown is for illustrative purposes only and a grid with much more metallic surface can be used inasmuch as normally the top will be hermetically sealed to the tray and the tray will not be used for the purposes of furnishing ice merit therein, a cover for said tray hermetically closing said tray and arranged to receive heat from said metallioeheat conducting element, said cover being provided withga eries of grooves adapted to receive a liquid to be cooled in said grooves, which are provided with an inlet element and an outlet element, said grooves forming a continuous channel so inclined that liquid poured into the grooves will pass through the channel to the outlet by gravity.

2. Appliance for cooling liquids, comprising an ice tray having a metallic heat conducting element therein, a vcover for said tray hermetically closing said tray and arranged to receive heat irom said metallic heat conducting element, said cover being provided with a series of grooves adapted to receive a liquid to be cooled in said grooves, which are provided with an inlet element and an outlet element, said groovesforming a continuous'channel so inclined that liquid poured into the groove will pass through the channel to the outlet by gravity, and a detachable cover for said grooves.

3. Appliance for cooling liquids, comprising an ice tray having a metallic heat conducting ele- 25' ment therein, a cover for said tray hermetically 1 closing said tray and arranged to receive heat from said metallic heat conducting element, said cover being provided with a series of grooves adapted to receive a liquid to be cooled in said grooves, which are provided with an inlet element and an outlet element, said grooves forming a continuous channel so inclined that liquid poured into the grooves will pass through the channel to the outlet by gravity, said cover being also provided with a raised portion forming a pocket for the air in the tray.
