In addf tion, the lower edge of the partition I3 is provided with a. spoutl 24 at its central portion'and the rear edge of the partition is provided with a raised bead 25 at either side of the spout 24 to restrict the flow of water to the spout 24. As indicated in Figures 4 and 7, the bead extends completely around the partition I3. It will be understood that the spout 24 overlies the upper end of the drain pipe I'I so that water formed by the melting of the ice is caused to flow out of the refrigerator through the drain pipe.

The partition I3 is supported from the inner walls of the refrigerator by means of screws 26, as best seen in Figure 4, the upper plate 2D having down turned flanges at the sides of the partition, as best seen in Figure 7, these flanges being provided with slots indicated at 2! to be engaged over the screws 2S. This assembly provides for ready removal of the partition when desired.

Extending forwardly from the rear wall of the cooling compartment is an apron 30. The apron 30 may extend completely across the back of the refrigerator, but at all events it extends completely across that portion thereof which is adapted to receive a block of ice. The forward edge of the apron 30 overlies the rear edge of the partition I3 so that water intercepted by the apron 3|] drops olf its forward edge onto the partition I3 adjacent its rear edge.

As best seen in Figure 2, the partition I3 is mounted in the refrigerator so that it is inclined downwardly and rearwardly at a substantial angle. This angle may be between 5 and 10 and is preferably in the neighborhood of 7 from the horizontal. This inclination of the partition I3 serves a dual purpose. In the first place, it provides for flow of water deposited therein from melting ice toward the rear end where it passes over the spout 24 and hence out the drain pipe I1.

More important, however, is its function in controlling the flow of air in the refrigerator. Cooled air is caused to flow by the inclination of the partition downwardly at the rear of the refrigerator and upwardly at the front thereof, as indicated by arrows in Figure 2. The front and rear edges of the partition I3 are spaced a substantial distance from the inner surface of the door and from the inner surface of the back wall of the refrigerator, respectively, so as to permit a substantial flow of air through the spaces defined thereby.

By providing substantial insulation between the upper and lower surfaces of the partition I3 two importantY additional advantages are achieved. In the rst place, the provision of this insulation maintains the lower surface of the partition I3 at substantially the same temperature as the other walls of the food storage compartment. It will be appreciated that in the absence of such insulation the upper wall of the food storage compartment would be maintained at a relatively lower temperature, either by direct conduction from the cooler air in the cooling compartment or by dropping of water resulting from melting ice thereon. This would have the effect of providin-g a surface at the top of the food storage compartment on which moisture would tend to condense and the condensate would then drip downwardly upon food in the food storage compartment, since the temperature of the partition would not be suilciently low to freeze the moisture --deposited thereon. This undesirable eifect is completely avoided by the provision of the substantial insulation referred to.

A secondary undesirable effect is also avoided v by the provision of the insulation which maintains the lower surface of the partition I3 at sub.. stantially the same temperature as the other walls of the food storage compartment. This second- Y ary undesirable effect which is avoided is a restricted circulation of air within the food storage compartment itself. It will be appreciated that if the lower surface of the partition I3 were relatively Ycolder than the other walls of the food storage compartment, air passing downwardly at the rear of the food storage compartment would then circulate upwardly at the front of the icebox and certain of this air would strike the lower surface of the partition and would thereby bev cooled and would set up a restricted circulation in the food storage compartment so that the amount of air `passing upwardly from the food storage compartment to the cooling compartment would be seriously reduced.

It was previously mentioned that the partitionV I3 is shaped so thatA its upper surface is inclined downwardly from the side edges thereof toward the center thereof. This causes the water dripping from the melting ice to flow to the center vthereof and thence out the spout 24. It also has a further advantage in that it tends to distribute cool air, as will now be pointed out. It was stated at the outset that the cooling compartment was provided with a mechanical refrigerating unit or ice cooling means as circumstances required. The

arrangement is such that when the mechanical refrigerating unit is in use the cooling effect thereof is located at one side of the cooling compartment. In like manner, when ice is relied upon for cooling, the cooling thereof is effective only in the other side of the cooling compartment. By providing a partition which inclines downwardly from its side edges, air which is cooled by either of the cooling agencies alternatively employed is directed noi-l only toward the rear of the icebox but also toward the central portion thereof.

It will be appreciated that the provision of theV ondary circulation solely within the food storage compartment.

It will therefore be seen that the present construction provides a very efficient combination ice and mechanical refrigerator in which the cooling effect ofthe particular cooling agency em ployed is substantially augmented by the controlled flow of air in the refrigerator.

While I have illustrated and described a pari ticular embodiment of my improved combination lice and mechanical refrigerator, it will be understood that this has been done solely to enable those skilled in the art to ypractice the invention, the scope of which is indicated by the appended claims.

2. A combination ice mechanical refrigerator comprising a box having an open front, a door closing said open front, a cooling compartment at the top -of said box, a mechanical cooling unit at vone side of said compartment, a member for supporting ice at the other side of said compartment, air ow controlling means dividing the interior of said box into said cooling compartment and a lower food storage compartment comprising a plate spaced from the rear wall of said box and the door thereof, said plate being transversely inclined downwardly and inwardly from the side edges thereof to direct downwardly moving cold air from either side of said cooling compartment toward the center of the box, said plate being downwardly and rearwardly inclined from the front edge thereof to direct cooled air rearwardly of the box, and a ledge extending forwardly from the rear wall of said box at the bottom of said cooling compartment effective to direct downwardly moving cold air from said cooling compartment onto said plate, said plate serving also as a drip pan and having a pouring spout at its rear edge centrally thereof.

3. A combination ice mechanical refrigerator comprising a box having an open front, a door closing said open front, a cooling compartment at the top -of said box, a mechanical cooling unit at one side of said compartment, a member for supporting ice at the other air ow controlling means dividing the interior of said box into said cooling compartment and a lower food storage compartment comprising a plate spaced from the rear wall of said box and the door thereof, said plate being transversely inclined downwardly and inwardly from the side edges thereof to direct downwardly moving cold air from either side of said cooling compartment toward the center of the box, said plate being downwardly and rearwardly inclined from the front edge thereof to direct cooled air rearwardly of the box, and a ledge extending forwardly from the rear wall of said box at the bottom of said cooling compartment effective to direct downwardly moving cold air from said cooling compartment onto said plate, said plate serving also as a drip pan and having a pouring spout at its rear edge centrally thereof and a drain pipe located to receive water from melted ice below said spout.
