I Application filed'september 8, 1911. Serial No.648,298.

ing anaXial ice compartment therein and revolving shelves arranged around the said ice compartment.

A further object is to provide a novel means for the circulation of air within the refrigerator.

This invention is embodied in certain novel constructions and arrangement of parts as hereinafter described and as pointed out in the appended claim, the invention be- .ing illustrated in the accompanying, drawing, wherein similar reference characters indicate similarparts, and wherein the refrigerator is shown in vertical section through the center thereof.

Referring in detail to the drawing, the casing of the refrigerator comprises the outer shell or wall 5 and the inner shell or wall 6 forming a compartment therebetween and having an opening 12 through the top thereof. A door opening 14: passes through the side of the said casing. A nipple 15 is'provided on the top of the outer wall 5 through which the compartment between the walls 5 and 6 may be filled with water or any other suit-able fluid and a cap 16 is provided for closing the passage through the said nipple. The casing of the refrigerator is cylindrical in form and the opening 12 in the top thereof is arranged at the center or at the axis of the refrigerator casing. A cylindrical perforated support 3 depends from the said opening and is provided at its lower endwith a plurality of peripheral. openings 4. This support forms the ice compartment and within thev same is arranged a cage 13 which seats on r the lower end thereof and is spaced from the sides of the said support. This cage is adapted to hold the. ice therein and keep theice outof contact with the sides of the support. A cover 11 is inserted into the upper end of the support 3 and. forms a closure for the opening 12. This cover when removed allows the insertion of ice into the ice compartment. mounted on the support 3 and a circular shelf 1 is mounted on each of the said rings to rotate or revolve around the support,the periphery thereof being spaced from the casing .of the refrigerator. A drain pipe 7 is connected to the bottom ofthe support 3 and passes into the sleeve 8 which passes through the bottom of the casing and is provided with the usual cup 9 onthe lower end thereof for permitting the escape of drain water but preventing the inlet of air. The casing is preferably mounted on legs 10 and a drain valve 17 is provided on the lower end or bottom thereof for' permitting the compartment between the shells '5 and 6 to be emptied.

The edibles or other objects to be preserved are placed on the shelf 1, which by being rotated can be completely filled around the same. The air within the refrigerator circulates in a novel manner, the warmer air rising around the peripheries of the shelves andthe cold air passing downward between the cage 13 and the support to pass through theope'ning 4 at the lower end ofthe sup- --port thus forming a continuous circulation of air and'permitting the air to pass intothe support" and around the ice of the cage. The ice in being contained in the cage is prevented from coming in contact with the support. 7 This circulation of air thoroughly cools the air within the refrigerator the water or other liquid contained withinthe casing of the refrigerator becomes cooled and remains cool and sweet. The air in being permitted to pass through the support 3 prevents sweating of the inside of the refrigerator.

' The refrigerator is economical for the rea son that it necessitates only a small supply of ice to retain the interior at a low degree oftemperature, is convenient in its use and is hygienic and simple in its construction.

What is claimed is A plurality of rings 2 are In ar'efrigerator, a cylindrical casing having a door-opening in its side, a cylindrical foraminous support depending therein, a cage arranged within the support and spaced from the sides thereof and adapted to contain the ice, a plurality of rings secured to the support, and a circular shelf arranged on each of the said'rings and having its periphery spaced from the sides of as my own, I have hereto aflixed my sigthila casilng, Whe'eby thke cold alior may cifiinature in the presence of tWo Witnesses. cu ate oWnWar ly in t e space etwcen t e cage and support and the air pass upwardly WILLIAM BURK' 5 between the shelves and the casing to form \Vitnesses:

a continuous circulation around the shelves. C. L. DU PoY,
