Money, Cinciti, Ohio, assignor to The Crosley Radio Corporation, Cincinnati, Ohio, or corporation of Ohio Application January 15, 1935, Serial No. 1,909 (c1. cz-ce) My invention relates to'the provision of means vention has some points in connection with such of cold air from domestic refrigerators, and at the same time increase rather than decrease the relation to refrigerators in general. 5 convenience thereof in use. When the door of a refrigerator is opened and immediately closed again, there is not much in crease of heat due to in?ux of outer air and ef ?ux of cold air within the refrigerator. How 10 ever, upon holding the door open for longer pe riods of time, this loss becomes more of a factor. What happens is that the cold air flows out from 15 a door, which are distinctive, as well as having The refrigerator of the mechanical type,- as a illustrated, has a casing i which is insulated and surrounds a compartment 2, in which compart ment is located the refrigeration unit 3, having ice trays It therein. This unit is located in the upper part of the compartment so as to set up 10 proper circulation of air therein, to maintain the entire compartment cold. " the bottom of the refrigerator, to be replaced by The door, as shown, has a body t, which has a warm air from without flowing in at the top. It is my object to impede the flowing of cold air out of the bottom of the refrigerator by means hollow chamber 6 in its inner side, surrounded by a wall of insulated nature. In this hollow 15 chamber there is arranged a rack of open wire of a plate which is movable and preferably hingedly connected to the refrigerator across the lower portion thereof and inside of the door thereof. This plate willthen maintain a pool for ready availability when the door is open. -.The insulation strip or “breaker" strip sepa frigerator where objects are kept which must be at the lowest temperature, and at the same time will make it hard for cold air to ?ow out of the the outside of the box, is shown ‘at d. The shelves t within the refrigerator can be ar» ranged as noted, leaving at least part way across the refrigerator a relatively high space it for storlng‘of bottles of milk or other beverage, large 25 20 of the coldest air in the lower portion of the re 2 UK with West Reissue Patent No. 19,008, and my in to impede in a simple and effective way the loss refrigeration compartment. It is my object, further, to make of this plate when it is opened to gain easier access to the lower portion of the refrigeratorcompartment, a shelves ‘l, on which many articles can be located, ' ' rating conductively the compartment lining from pieces of meat and the like. in the particular form shown, this space is only shown as extend ing partly across the bottom of the refrigerator. Located on hinges i i set between the box wall and the breaker strips near the bottom of the merely placing intervening articles on the said refrigerator compartment, is a plate it, which is of a size to close oft" from the outside the lower ‘ tray. ' I believe, furthermore, that the presence of this . portion of the said compartment. Urdinarily this plate across the lower portion of the refrigerator plate will be as high as the high space for bottles, etc. above referred to. 35 35 compartment, when the door is open, will deflect Spring socket plates it or other suitable retain= air currents from without so that there will be a reduced tendency of cold air spilling out of the ing means serving to engage the edge of the plate, in this instance a knob its, and keep it in erect compartment above the plate. _ position as shown in Figure 1, will be provided I accomplish my objects by that certain con 40 struction and arrangement of parts of which an on one or both of the side walls of’ the refrig 4.0 . example will be speci?cally described and the erator compartment. The plate need not be movably mounted in the novelty of which will be set forth in the append manner noted, as some other means for remov ed claims to which reference is hereby made. ably retaining it in place would serve. How In the drawing: tray upon which articles can be moved in order '30 to make it. easier to select a given article by Flgure 1 is a vertical section taken centrally of a refrigerator at the compartment portion thereof. Figure 2 is a perspective of the lower portion 50 of a. refrigerator with the plate open. Figure 3 is a fragmentary section along the line M of Figure 1. Figure i is a fragmentary section along the line of Figure 1. , I have illustrated my invention in connection 55 with a door which is constructed in accordance ever, by articulating the plate at the bottom it 45 can be used as an article supporting tray. To this end one way of arranging the structure will be to place rubber bumpers/ill, it, on the outside of the plate. which bumpers will rest upon the , breaker strip when the plate is turned down, and 60 hold the plate in a horizontal position. The convenience, of being able to arrange ar tlcles on the tray is apparent, but it has particu» lar advantages at the bottom of ‘the food com partment because of its use in relieving conges- 55 i auavss tion of articles there, while removing or insert ing others. The plate when erected will probably not be 1. In a domestic refrigerator having an undi vided food compartment, a refrigeration unit in the upper portion of said food compartment and lowered except occasionally in the use of the re frigerator. It will not interfere with access to the ice trays, nor to the upper shelves, and the shelves in the door will, of course, be available. a door for said compartment, a plate hingedly mounted on a horizontal axis at‘ the front por even in hot climates to provide any vent holes retaining said plate in horizontal position when tion of the bottom of said food compartment, and means for retaining said plate in an erect posi In connection with the shelved door compart tion, said plate being of a size to extend substan ment, the tray will act to assist in maintaining _ tially across said food compartment and of a a separate current of air in the door compart height to terminate near but below the lower por ment. I do not believe that it will be necessary tion of said refrigeration unit, and means for in the plate to assist in refrigeration action in . said door is open so that said plate may act as the door compartment. Also, if shelves were l6‘ placed on the inside of a door, rather than in a ' compartment in a recess therein, the presence of the plate would assist in setting up a di?'erent current of cold air washing the door from that which moves through the body of the refrigerator. So far as saving in loss of cold air when open ing the door is concerned, it should be noted that the easy way for cold air to get out of the food compartment is at the bottom, and that it is at the bottom where the coldest air is normally found. The plate not only impedes ?ow of cold air out of the refrigerator which drains the cold est portion of the compartment, but it greatly impedes the loss of cold air from above because of the air currents within and without the box tending to maintain themselves. Having thus described my invention, what I claim as new and desire to secure by Letters Pat eat, is:— ‘ a temporary ‘shelf. ’ 2. In a domestic refrigerator having an undi 15 vided refrigerated compartment, a refrigeration unit in the upper portion thereof, and a door for said compartment, a plate hingedly mounted on a horizontal axis at the front portion of the bot tom of said compartment, means for retaining 20 said plate in an erect position, said plate being of a size to extend substantially across the said food compartment and of a height to terminate near but below the lower portion of the refrigeration unit, means to hold said plate in horizontal po 25 sition when said door is open so that it may act as a temporary shelf, shelves in said food com partment and shelves on said door, said shelves in said compartment and on said door being so proportioned in length as to leave space for said 30 plate in upright position in said refrigerated compartment when said door is closed.
