One object of the invention is to provide an improved cooling cabinet which is so constructed 5 that a positive and unrestricted ?ow of cooling medium is maintained around and in contact with the objects to be cooled. Figure 5 is an enlarged horizontal cross-sec tional view taken on the line 5-5 of Figure 3. In. the drawing, the numeral Ill designates an elongate rectangular cabinet or housing, which is, formed of an outer shell II and an inner shell 5 l2 spaced from each other and suitably con nected together.’ The space between the walls , and bottoms of the shells is ?lled with an insu An important object of the invention is to pro lating material‘ l3, such as cork, or the like. vide an improved cooling cabinet 01' the charac .1o ter described having partitions mounted therein The inner-shell I2 is made of a material suit- 10 for forming a plurality of compartments for re _ able for holding a liquid cooling medium, such ceiving objects to be cooled, said partitions being as salt brine.‘ Short legs or blocks III’ are pro vided at the corners of the bottom of the cabi foraminous whereby the ?ow of the cooling me to support said cabinet on the ?oor or other dium throughsaid compartments‘is unrestricted , net surface. A sliding cover ll’ of theusual type 10 15 by the partitions. is arranged to close the top of the cabinet. Another object of the invention is to provide an improved coolin'g cabinet having a chamber for receiving objects to be cooled and an elongate restricted passage communicating with the chain; 20 her and having a cooling element therein, so that when a cooling medium is circulated through the chamber and passage, said medium is sus A vertical baille ll, havinga height substan tially the same as the side walls of the cabinet, is mounted transversely within the cabinet near one end thereof, whereby the interior or said go cabinet is divided into. a large liquid containing compartment A and a dry cooling compartment tained in intimate relation with the cooling ele v1B. A three-sided casing I5 is mounted within the ~ ment while traversing the passage whereby the large‘ compartment A, and has its end walls con nected with the side wall of said compartment; 25 a eiIect of the cooling element upon the medium is ‘whereby a substantially rectangular chamber 0 _ N) ampli?ed and the maintenance of an even. tem is formed at one side of the compartment A.

The invention will be more readily understood from a reading of the following speci?cation and central vertical partition I! extends longitudinal ly of the chamber between the battle l8_and the opposite end wall It thereby dividing the cham ber‘into two parallel sections. 40 (A pInrality-oFIoi-aminous partitions 20 are mounted in relation within each section of the chamber'C and extend transversely there- of. ' Each partition is formed'of a section of by reference to the accompanying drawings,v in' hardware cloth 2|, or other suitable foraminous. 45 which an example of the invention is shown, and metallic frame 22. The partitions are preferably removable, being adapted to ?t in channel mem wherein: ' , Figure l is in isometric view, partly in eleva material. having its edges con?ned within a - tion and partly in section, of a cabinet construct- ~ bers 23 provided on the walls of the chamber and ‘,0 ed in accordance with the invention, Figure 2 is a plan view of the cabinet,‘ Figure 3 is an enlarged transverse vertical sectional view taken on the line 3--3 of'?gure 2, Figure 4 is a transverse vertical sectional view ;5 taken on the-line 4-—4 of- Figure 2, and _ the longitudinal partition i9, whereby they may 50 be readily and quickly inserted or removed to divide each section of the chamber into compart ments'. Openings 24 are provided" in the end wall ii of the casing whereby communication is established 55 2 2,109,714 between each section of the chamber C and the passage E. Similar openings 25 are provided in the baf?e l8 for establishing communication be tween the sections of the chamber C and the space between said baiiie and the end wall H of the casing. The openings 24 and 25 are prefer ably covered with hardware cloth or other foraminous material. A circular opening 26 is provided centrally of the end wall ll of the casing 10 and an annular ?ared collar 21 surrounds the opening and extends into the chamber. An impeller or fan 28 is mounted within the opening 26 on a shaft 29 which extends outwardly therefrom through a ?uid tight bushing 30 in 15 the end of the cabinet. A pulley 3| is mounted on the outer end of the shaft and belts 32 con nect the pulley with the drive shaft of’ a motor 33, whereby the impeller is driven by said motor. The blades of the impeller are arranged to force 20 a cooling medium within the cabinet from the passage F into the chamber C in the direction of the arrows (Figure 2). It is noted that the impeller is located in alinement with the longi tudinal partition I! whereby a cooling medium, 25 such as brine, actuated by the impeller, is directed equally into the sections of the cham ber C. A cooling element 34 is mounted within the elongate passage D and includes a coil formed of a plurality of longitudinally disposed pipes 35 80 spaced vertically within said passage. The ends of the coil extend outwardly through suitable bushings in the end of the cabinet and are con nected to a source of refrigerant (not shown). Drains 38 are provided in the bottom of the a therebetween within each section of the chamber C may be readily and quickly varied. Manifestly, circulation of the cooling medium through the ‘compartments is unrestricted due to the fact that the partitions are made of a foraminous mate rial. It is noted that the provision of the cooling coil 34, within the elongate passage D reduces the amount of space usually occupied by such coils to a minimum, thereby increasing the amount 10 of space within the cabinet available for use as a cooling chamber. Also, such an arrangement makes for a more compact structure, thereby re ducing costs of materials and manufacture. Due to the fact that the cooling medium en 15 gages the baf?e M, a heat transfer is made possible whereby the interior of the chamber B is cooled. Since no liquid cooling medium enters this chamber, objects which cannot be immersed in a liquid may be readily cooled therein. -It is pointed out that due to the position of the impeller 28 with relation to the longitudinal partition l9 within the chamber C equal streams of cooling medium are forced through each section of the chamber, thereby insuring the 25 inmaintenance of an even temperature therein. What I claim and desire to secure by Letters Patent is: 1. A cooling cabinet including, a housing hav-_ ing a. chamber therein for receiving objects to be cooled, a longitudinal partition within the cham ber and dividing the same into sections, a cooling element within the housing and outside the cham ber, means at one end of the chamber for cir compartments A and B whereby liquid in said culating a cooling medium through the sections of the chamber and into contact with the cooling compartments may be removed therefrom. In use the large compartment A is filled with - element, said medium being constantly re-cycled a liquid cooling medium, such as salt brine or ‘the through the chamber and over the element, and like, and bottles, cans or other obi ectsto be cooled removable foraminous partitions within the sec are placed within the compartments formed by tions of the chamber for forming a plurality of the foraminous partitions 20 within the chamber compartments therein and permitting an unre C. > The impeller, actuated by the motor 3!, stricted flow of cooling medium through said forces the cooling medium equally through both sections of the chamber C and outwardly through 45 the openings 2| in the end wall of the easing into the passage E. The medium is then forced from the passage E in the direction of the arrows (Figure 2) into the elongate passage D having . the cooling coil 34 mounted therein. The brine 50 is cooled while traversing the passage D and is directed therefrom into the passage F from which it is moved by the impeller 28 through the open ings 25 into the chamber C, whereupon the cycle is repeated. 56 , Such circulation of the cooling -medium, con stantly re-cycling said medium through the cool ing chamber C, the passage E, over the cooling coil in the passage D, and leading through the passage F to the chamber C, obviously serves to 60 maintain an even temperature within the cabinet. In traversing the elongate narrow passage D, the cooling medium is sustained in intimate rela tion with the cooling ‘coil positioned therein, be cause of the restricted passageway therethrough. 65 Due to such intimate relation and the length of the passage it will be seen that the cooling effect of the coil upon the medium is amplified and the maintenance of an even temperature is facili tated. 70 - The provision of the partitions 20 makes it I possible to divide the chamber C into a large number of compartments for separating various sizes or kinds of objects to be cooled from each other. Since the partitions are removable it will 75 be seen that the size of the compartments formed compartments. ' 2.
