(01. 62-31) This invention relates to ice refrigerators and Fig. 2 is a plan view of the rack shown in Fig. 1; its general object is to facilitate the operation of Fig. 3 is a_ sectional view of the rack on the introducing a cake of ice into the ice compart line 3-4 of Fig. 1; ment and upon the ice rack for initial icing and Fig; 4 is a detail enlarged sectional view; r; for re-icing. Refrigerators are now being made with the ice supporting bars of the ice rack located in a plane below the sill of the ice compartment door so that when the cake of ice in use has melted down 11, to or about the level of the sill a fresh cake of ice can be slid into place on top of the cake then in use. In one type of refrigerator for which my invention is adapted the ice rack is located be tween the ice compartment and the food com l5 partment, and the circulation of air in the food compartment contacts the ice at the bottom of the cake and the cake melts level, or substan tially level, at the top so that if care is exer cised in re-icing as soon as the top of the cake ‘ is at or about the level of the door sill the fresh ‘20 cake can he slid into place very easily on the cake in the ice compartment. The rack bars are located below the level of the door sill and in re-icing the cake may be left partly supported 25 on the top of the front rail of the ice rack and in a tilted position on the ice cake in the refrigera tor. In initial icing the ice cake may be unevenly placed on the ice rack bars and left in a tilted position on the ice rack, partly resting on the g front rail of the ice rack, or the cake may be slightly oversize and left in a tilted position. It is desired to have the ice cake rest ?at upon the ice rack in initial icing, or upon the ice cake remaining on the rack in re-icing, especially in refrigerators of the under-ice circulation type, one form of which is shown in my copending ap plication Serial No. 69,802, ?led March 20, 1936. The object of my invention is to insure that the cake of ice introduced into the ice compart 4 ment in initial icing or in re-icing shall be received and supported on the ice rack in a level position. Another object is to provide a rack having rack bars located below the level of the door sill of d the ice compartment with bars extending from front to rear thereof and forming skids to receive the ice cake and to support the ice cake tempo rarily above the other rack bars. A further object is to provide means where by my invention can be applied readily to refrig erators now in use. In the accompanying drawings— Fig. l is a vertical sectional view of a portion of a refrigerator showing my invention embodied 55 in the rack thereof; Fig. 5 is a sectional view of a rack showing my 5 invention applied thereto; _ Fig. 6 is a sectional view on the line 8-. of Fig. 5i and » Fig. 7 is a perspective view of the attachment employed for embodying my invention in racks 10 now in use. Referring ?rst to Figs. 1-4, 8 indicates a refrig erator cabinet having an ice compartment 9 and a door l0 therefor, and a food compartment H and a door I 2 therefor. A front ledge l3 and a 15 back ledge H are arranged at the front and at the back of the cabinet between the ice compart ment and the food compartment and below the level of the sill ii for the ice compartment door Ill. The ice rack comprises a front rail I 8, a back 2° rail l1, and a plurality of parallel rack bars l8 secured to and supported on the front and back rails. ‘The ice rack is supported in the cabinet upon the ledges i3 and I 4 with the top of the bars l8 located below the level of the sill I5. The front rail inclines forwardly and is made of sheet metal which is bent over to provide a rounded top It’ located inward of the sill and preferably just a little above the level of the sill. The front rail of the refrigerator provides a convenient skid rail in introducing the ice cake into the ice com partment. Keepers is are fastened to the back wall of the cabinet and engage openings 20 in the back rail I‘! to prevent the rack from tilting 3,. upward at the back when an ice cake is skidded over the front rail into position on the ice rack or upon a reduced cake remaining upon the rack. Modern ice refrigerators are made with ice com partments and doors of proper dimensions to re " ceive ice cakes of predetermined weight which 40 are, generaly speaking, of predetermined dimen sions. It is important that the ice cake should melt evenly and maintain a substantial level at the top and that the‘ refrigerator should be re iced by the introduction of a fresh cake before the ice in the refrigerator has been exhausted and while a reduced cake of su?icient thickness to cover the ice rack remains. When the top of the ice cake reaches the level of the door sill it will indicate time for re-icing and the thickness 60 of the reduced cake will furnish ample margin of time for this purpose. The rack bars are made of metal and penetrate the ice cake, forming ice ?ns between the bars, and if the body of the cake 55 2 2,118,185 completely melts away the ice fins would be sep arated and ?nally drop through between the rack bars into the usual drain pan, and waste ice; but if re-icing is done before the body of the ice cake has completely melted away and while the reduced cake is an inch or more in thickness and the fresh cake is placed ?atly and evenly on the reduced cake, there will be an adherence between the re duced cake and the fresh cake sufficiently to pro-. v10 duce a continual normal operation without sep aration and dropping of the ice ?ns when the body of the reduced cake is completely melted. For these reasons it is important, as before stated, that the fresh cake should be placed squarely and 15 ?atly upon the rack in initial icing and in re-iclng. The dimensions of the ice cake and of the ice compartment and the door therefor, with a little care on the part of the iceman, insure the square positioning of the ice cake in the ice compartment, 20 but because the rack bars are located a substan tial distance below the level of the door sill it is possible to initially ice or to re-ice and leave the cake tilted rearwardly in the ice compartment. And this tilted position may not be readily notice strip 24 has a ?ange 24’ which rest upon the rack bars 21 whereby the frame is supported upon the rack, and the frame has slots 28 to engage keepers which are provided on the back wall of a refrigerator cabinet to project over the back rail in of the rack bar to keep it from tilting up at the back when an ice cake is skidded into the ice com partment over the front rail. In both forms of my invention the rack bars and the attachment are made conveniently of galvanized sheet metal. The rack bars are shown in one form which has been found satisfactory but the invention may be used with rack bars or other forms and with racks differing otherwise in construction than herein shown and described. The skid bars receive and support the cake of ice in level position for initial icing and, if they are exposed, for re-icing, and they insure that the ice cake will be positioned levelly with respect to the ice cake when placed in the ice compartment. 20 I have shown the invention as it may be em bodied originally in an ice rack and as it may be adapted by attachment to an existing rack, but ‘I do not limit the invention to the particular It is form, construction and arrangement of parts 25 objectionable to have the ice cake tilted in the ice shown'and described and reserve the right to compartment directly upon the rack or upon a make any changes necessary or desirable to adapt reduced cake on the rack because the desired the invention to different kinds and sizes of re frigerators and for other purposes within the under-ice circulation will not be properly main 30 30 tained and the cake will melt unevenly and more scope of the following claims. I claim: rapidly and the e?iciency of the refrigerator is 1. An ice rack for refrigerators comprising a likely to be impaired. I provide the rack with skid bars 2| which ex ‘ plurality of parallel rack bars, and a pair of skid tend in parallel relation from front to back of the bars arranged with their tops parallel with and rack. The top of these skid bars is preferably above the rack bars to receive and support a cake 35 about the level of the sill of the ice compartment of ice. 2. An ice rack for refrigerators comprising a door and of the top of the front rail and back rail of the rack. However, I prefer to have the plurality of rack bars secured together in sub top of the front rail of the rack which provides stantially parallel relation, certain of said rack bars being spaced apart and extending above the 40 40 a skid for the ice cake slightly above the door sill and the skid bars 2|, as shown in Fig. 1. The tops of the other rack bars with the tops of said front rail thus provides a support for the ice cake certain bars in a single plane. 3. An ice rack for refrigerators comprising a while it is being inserted in the ice compartment and thereby protects the sill from damage from front rail and a back rail, rack bars secured to the cake and facilitates placing the cake properly said rails, the tops of certain of said rack bars 45 being adjacent the top of the front rail and the on the rack. The skid bars can be made conveniently, as tops of the other rack bars being located below shown in Figs. 1-3, by increasing the height of at the top of the front rail and the tops of said cer least two of the rack bars, and when the ice cake tain rack bars. _4. An ice rack for refrigerators comprising a 50 50 is located upon these two skid bars 2| in initial icing the skid bars will quickly melt into the front rail and a back rail, and a plurality of rack cake until the latter is resting upon the other bars secured at their ends to said ‘rails and ar bars l8. In re-icing the fresh cake will rest upon ranged in substantially parallel relation, cer the skid bars 2| which rapidly melt therein until tain of said rack bars having their tops adjacent 55 the fresh cake rests upon the reduced cake on the tops of the said rails and the tops of the 55 the bars l8. These skid bars 2i facilitate the other rack bars being located adjacent the bot operation of positioning the ice cakes squarely in toms of said rails. 5. A refrigerator comprising an ice compart the ice compartment and temporarily support the cake in a level position so that the cake will ment and a door and a door sill therefor, an ice rack comprising a plurality of rack bars, cer 60 60 maintain its square and level position in the re tain of said rack bars having the bottoms thereof frigerator. To adapt my invention to refrigerators now in in alignment with the bottoms of the other of use I provide an attachment, Figs. 5-7, in the said rack bars and extending above the tops of the form of a frame comprising skid bars 22 secured other rack bars, and means for supporting the 85 to the front strip 23 and the back strip 24. This rack at the bottom of the ice compartment with frame is adapted to be placed on the rack of a the tops of said certain rack bars in substantially refrigerator which is not initially equipped with the same plane with the sill of the door and the skid bars,- and when so positioned the front strip tops of the other rack bars substantially below will rest against the front rail 25, Fig. 5, of the the horizontal plane of the sill of the door. 6. A refrigerator comprising an ice compart 70 rack. the back strip will rest against the back ment and a door and a door sill therefor, an ice rail 26 of the rack, and the skid bars 22 will over lap slightly the top of ‘two of the rack bars 21, rack comprising a front rail, a back rail and a Fig. 6, to provide skid bars comparable with the plurality of bars connected at their ends to said skid bars 2| of the unit rack shown in Figs. 1-4. rails, certain of said rack bars extending above 75 The front strip 23 has a ?ange 23’ and the back the tops of the other rack bars and having their 75 25 able to the iceman, especially in re-icing. 3 z tops adjacent the top of the front rail, and means and comprising a pair of skid bars adapted to for supporting said rack at the bottom of the ice receive and support. acake of ice above the other compartment with the tops of the front rail and bars, one of said skid bars being arranged in of said certain rack ‘bars in substantially the juxtaposition to and cooperating with one of said same plane! with the 'door sill. rack bars and the other of said skid bars being 7.
