This invention relates to household and com mercial ice refrigerators, and the principal object of the invention is to provide a novel ice grid which will increase the efficiency of the ice for 5 ~ refrigeration purposes, the grid exposing only the in connection with a refrigerator casing of the “one door” type having side walls A, top B, bot tom C and'a. back D, and having a single door E at, the front which when opened gives access’ to the ice compartment above the grid, and like wise access to the food compartment disposed‘ below the grid. However my grid may be used in connection withvother types of ice refrigerators bottom surface of the ice block to the circulating air within the refrigerator casing by a unique arrangement of parallel metal plates disposed having two or more doors, also with refrigerators edge wise to the ice block, which arrangement 10 considerably increases the cold surface area along which the air passes, the air currents rising at the sides of the refrigerator casing and entering the grid from the end and passing along the grid plates to the center of the grid from whence the having certain doors installed for icing. pur poses only. 10' » The ice compartment, in' the upper portion of‘ the casing, is shown as provided at‘ the‘ sides A-—A and back D with a rustless' lining ‘l, the lower ends of which at the sides A'—-A of the air currents drop into the food compartment, 15 thereby causing the ice to melt substantially from cabinet are de?ected inwardly as at la to form a support or bracket for the ice grid, hereinafter the bottom side of the block only. Another object of the invention is to provide described. While the bracket portions ‘la are a novel ice grid comprising a series-of relatively shown integral with the lining ‘l the same may if’ desired be formed separately therefrom and 20 long parallel metal grid plates disposed edge wise to the block of ice, and-extending from side secured to the Walls;A—-A in any desired man. to side of the ice compartmenmvvith shorter' ner. The lower ends-of the'bracket portions ‘la metal grid plates interposed between the pairs of longer plates, together with an interlocking mem 25 ber disposed transversely of the grid plates and serving to render the grid rigid, to divert melt age, and to control air circulation. ' A further object is to provide a grid having plates increasing in depth from side to center, 30 and provided with recesses at'their centers, the walls of which serve to divert the drip of ice melt age into aidrip pan disposed below the grid; said recesses also serving to provide an unobstructed 15' are ?anged inwardly as, at lb towards the center ‘ of the casing and then bent reversely as at 1c to clamp therebetween the inner ends of' plates 25 1d extendingfrom the sidewalls A-Axof: the casing, the-plates ‘(d not only serving to stiffen ' ‘ the shelf supporting "flanges lb of the bracket ' portions 1a and to maintain same properly spaced from the side walls of the casing, but also.serv— 30 ing to deflecttthe upwardly rising warmer‘ air cur rents» at the sides, A-—A of the casing below the grid inwardly towards and along the grid‘plates, ' passage for air currents in passing downwardly as shown by the arrows in Fig. 1. The ice grid-comprises a series of parallel rela 35 through an axially disposed slot in the drip pan 35 tively long plates 4' with shorter plates 3 inter into the food compartment. I will explain the invention with reference'to posed between theplates-ll as shown in Fig. 2, the the accompanying drawings which illustrate one, plates 3 and 4‘being disposed'ledgewiseto' the bottom- of 'a blockof ice, and rigidly connected practical embodiment thereof to enable others fa together by means of the-interlocking bar- l, tie vmiliar with the art to adoptand use the same; 40 plates 5, and'deflector' plate Z'as hereinafter de and. will summarize in the claims the novel fea tures of construction, and novel combinations of. scribed. The ends of‘ the longer plates 4 are ' notchedto provide’ shoulders 4a adapted to rest parts, for which protection is desired. upon the flanges ‘lb of the bracketportions'la.‘ In said'drawings: In order to connect the plates 4 together; tie Fig. 1' is a vertical section through a refrig 45 erator cabinet of the “one door” type, provided plates 5 extend over the tops of the plates 4 at with my novel ice grid, the section being taken ‘ their ends, the tie plates being ?anged dOWI1_-. wardly over the ends and under the bottoms‘of upon, the line l—|, Fig. 2. v the shoulders 4a- and secured thereto by welding Fig. 2 is a horizontal section through the re i - frigerator cabinet showing the arrangement of; or the like. The upper edge of each longer plate 4 is hori zontal, while the lower edge of each plate 4 slopes 2-2, Fig. 1. Fig. 3 is a vertical section through the'refrig- ' downwardly fromeachend towards the center, erator cabinet and grid taken on line ‘3-—3,' Fig. 1. the plates thus increasing in depth from the ends’ towards the center. vAt the center of the lower‘ 55 55%. I. In the drawings my novel ice grid is illustrated the ice grid, the section being taken on the line "2,134,085 edge of each plate 4 is a relatively large triangu ' " k ‘ at 9d to overlie the ?anged portion 42 of the front plate 411) of the grid, as illustrated in Fig. 3. Be low the lower end of and spaced from the plate 9d is a plate 9e extending downwardly to meet and stiffen the ?ange 9b which forms a shelf for supporting the front end of the drip pan 6 as shown in Fig. 3. Drip pan 6 is preferably of the insulated type and consists of upper and lower ?anged sheet lar recess 4b for the purpose of permitting con densation on the plate 4 to be carried to either side of the recess and fall uponja drip pan 6 below the grid, hereinafter described. The shorter grid plates 3, as shown in Figs. 1 and 2, are only about half the length of the plates 4 and have their ends 3a (Fig. 1) cut on a bevel sloping upwardly towards the center of the casing. The plates 3 otherwise have the same metal members 6a, 6b with. a layer of insulation shape and con?guration as the corresponding 60 therebetween, the upper pan. 6a serving as portions of the plates 4, and are likewise provided‘ ‘the lower half of the air ?ue and also as the with relatively large triangular recesses in their lower edges corresponding in size and shape with drip pan.. The lower pan 6b merely serves to protect the insulation 60 and to present a clean metal surface at the top of the food compart 15 ment. The drip pan 6 is spaced away from the side walls A-A of the refrigerator casing and is 15 the recesses 41) in the longer grid plates 4. , Extending across the tops of the assembled plates 3 and 4 at the center of the grid and dis posed at right angles to the plates is an inter-. provided with a slot 6d at its center which slot locking bar I serving three‘purposes; ?rst, to ‘ extends the full length of the grid; and has a ?ange 6e around its edges retaining the meltage 20 ice grid in placing the block in the'ice compart water. To assist the ?ow of air along the plates 20 permit the block of ice to initially slide over the ment; second, to resist any tendency of the ice block to shift laterally within the ice compart ment in event the grid is not level; and third, to 25 tend- to split the ice block into two parts which" will separate and slide laterally away from the de?ector plate 2 hereinafter described. The in terlocking bar I may be secured to the-plates 3 and 4 in any desired manner preferably by notch 30 ing the lower edge of the same to receive the up per edges of the plates 3 and 4 which may then ‘ be welded thereto. Obviously the upper edges of the plates 3 and 4 could be notched instead of bar I, if desired. The de?ector plate 2 extends transversely of 35 3 and 4 and also to assist in carrying off drainage water the sections of the drip pan at opposite sides of slot 6d slope downwardly towards the center of the casing. The front end of the drip pan 6 is supported upon'the ?ange 9b of the center rail 9, while the rear end is supported by angle clips secured to the rear wall D of the re frigerator casing, the drip pan 6 sloping generally downwardly toward the rear of the casing (85 30 shown in Fig. 3) so that the meltage water will ?ow into the drain tube 8. , The air circulation is illustrated by the arrows in Fig. 1, the warmer air passing upwardly along . the side walls A—A of the food compartment, and w the grid and serves three purposes; ?rst, to di inwardly towards the center of the casing in the 35 vert the meltage water to either side of the ?ue ' air ?ue formed between the bottom of the block opening 6d; second, to serve as the upper part of the air ?ue; and third, to support and locate the 40 shorter plates 3 of the grid; and as the de?ector plate is secured to all ‘of the plates 3 and 4 a very of ice and the drip pan 6, the air then passing along the grid plates 3 and 4, the major parts of the surfaces of which plates are exposed to the Warm air. The chilled air is then passedv down 40 substantial construction is provided. The de: wardly through the slot Ed in the drippan and '?ector plate 2 is slightly angular in cross-sec is thus returned to the food compartment at its tion (Fig. 1) with the'apex of the angle disposed center. in a vertical plane passing throughthe center of 45 The recesses 41) in plates 3 and 4 at their each of the plates 3 and 4, and the. side edges of , centers permit any condensation collecting on 45 the de?ector 2 terminate at points substantially above the widest portions of the recesses 4b in thelower edges of the plates 3 and I4. Prefer 50 ably the de?ector plateZ passes through, cor said plates tp be carried to either side of the 're- , cesses and to fall upon the drippan 6. . ‘The brackets ‘la, which maybe integral with or-separate from the refrigerator lining .1, extend respondingly shaped openings or slots ‘in the as- ' along each side wall A from the frontto the rear sembled plates 3 and 4 and is secured thereto by and serve to support the ice grid. These brackets welding; and if desired the de?ector :2 may be ': 1a slope downwardly and inwardly so as to con secured by welding to the interlocking bar I. 55 , ' ?ne the block of ice to the space directly over the At the rear end of the grid is a plate 43: (Fig. 3), 3 grid inasmuch as the ice chamber itself is soma the lower end of which is ?anged downwardly and rearwardly'as at 41,! and extends under the lower edge of the lining 1 on the back wall D of the casing; while at the front end of the grid is a plate 4w having its lower end ?anged down wardly and forwardly as at 4.2 to extend up toa portion of the center rail which is disposed across the front of the refrigerator casing. V The center rail preferably comprises a plate 9 65 extending across the entire front of the refriger ator casing between the side vwalls_A---A'at the height of the ice grid, the plate having its upper , edge ?anged obliquely downwardly as at 9:; tog wards the ice grid to assist in maintaining the 70 block of ice centered on the grid. The. lower“ end of the plate 9 is ?anged inwardly as at 9b. Below the lower edge of the ?anged portion 9a is a plate 90 which forms a continuation of the . ?ange 9a and slopes downwardly and rearward7 75 . ly, and has its lower edgeflanged downwardly as. what larger than the blocks of ice. Obviously 55 these inclined surfaces will tend to forcev the ice block directly over the grid, as will also the downwardly and rearwardly, plates 9a, 90 of the 7 center rail 9 which form continuations, of the 60 bracket portions ‘la. vThe ice grid is illustrated herein in connection’ with a so-called “one door” refrigerator, although 1 _ it is obviously applicable for use in refrigerators . of two or more doors, and also to refrigerators ‘ having certain doors installed for icing purposes only.’ I claim: . 65 . ’ ' g V ,1.
