REFRIGERATOR.

Application filed October 16, 1926.

This invention relates toimprovements in refrigerant containers for refrigerators and I especially to containers which are used for holding a mixture of salt and ice.

Among the objects of this invention, are to provide an ice container which,-

(a) Will be simple in construction;

(6) May be easily filled;

(0) lVill separate the refrigerant and provide for the easy passage of air therethrough, and

(d) Will provide a maximum amount of cooling surface with a minimum of expense.

The means by which these and other objects are accomplished, and the manner of their accomplishment, readily will be seen in the following description on reference to the accompanylng drawlngs, in which Fig. 1 is a sectional prospective View of one end of a refrigerator with a refrigerant container therein, the end of the ice container having been cut away to show the interior construction thereof.

Fig. 2 is a longitudinal section of the con tainer being the line IIII of Fig. 3,'and

Fig. 3 is a sectional elevation on the line III-III of Fig. 2.

Referring now to the drawings in which the various parts are referred to by numerals, 10 is the casing of the refrigerator made in any usual manner. 11 is a door in the top thereof through which door the refrigerant container may be raised or lowered and through which door it may be filled with a refrigerant such as ice and salt. This container comprises a bottom 12. perforated sides 13 and one perforated end 14-. The opposite end 15 of this container being the one away from the end of the refrigerator in whichthe container is located and being the end shown in Fig. 3, is preferably without perforations.

Disposed within the container are inclined shelves 16, which preferably extend from end to end thereof and are suitably attached to the side and end walls, as by rivets 17, 18, the shelves being; provided with flanges 1.9 and 20, to permit of such attachment. The container is preferably supported above the bottom of the refrigerator as by supports 21, which rest on the bottom.

It will be understood that while only one Serial No. 141,931(

container is shown the refrigerator box may be made with spaces at both ends for the refrigerant containers and one container be used at each end of such a box, or if it be desired, the container or containers may be otherwise located therewithin.

In use the door 11 is removed and the container lowered into the refrigerator and is then filled with crushed ice and salt. When so filled part of the ice and salt will be retained on each of the shelves and part in the central part thereof resting on the bottom. Even when freshly filled spaces will be left through which air may circulate, and as the ice melts such condition is accentuated. The warm air within the refrigerator rises to the top and as it comes in contact with the refrigerant container, is cooled, causing it to drop. The open spaces between the masses of refrigerant al lows the air to pass through the container as well as around the outside of the same and establishes a large cooling surface. The disposition of the shelves allows this air to pass downward and partially to be diverted outward through the perforations in the sides of the containers. It also allows additional air to pass directly downward through the centerof the container and the circulation of air thus set up, eventually causes a very thorough and eflicient circulation of the air within the refrigerator itself, and, an extremely efficient cooling action.

Much effort has previously been expended in an endeavor through the use of tubes and other devices, to open up a passage-way through the refrigerant whereby a large cooling surface may be exposed to the action of the air, a result which has been efficiently and simply obtained in the present construction by the separation of the refrigerant within the container so that free circulation except in. so far as such details may be spef cifically setout in the claims.

Having thus disclosed the invention, what is claimed is A refrigerant container, comprising a bottom, sides having perforations therer through, andends, and a plurality of oppowhereby a central open space is left be tween said shelves to permit filling said consitely disposed shelves each permanently set ainer Without removal of said shelves.

cured to a sicle and the said ends and extendmg upward from szud SlClG at an angle thereto, saicl shelves being considerablyless than half the Width 9f said container Intestimony of the foregoing I affix my signature.
