To this end andwi-nwaccordance with.'the teach- ,ings of: the presentijinvention the refrigerating .unitsandsupportswtheretorxform the-partitions by which :the-:.-rack =is divided: into a plurality-of independentqgenerally rectangular: open top binsor compartments.

The: supports; .being ,rmovable', permit adiustmentcof-rthedeneth 10f: the individnal=com-- natments, ethewidthwf .whiohweompantmentds preferably more or less permanent in a particular installation. Spacing members such as are used to cover the pipe can be provided in several lengths in a particular rack, thereby forming compartments of different sizes and by interchanging these members and malging corresponding adjustment of the supporting members smaller and larger bins can be repositioned in the rack as desired.
Referring now to the drawings in more detail, particularly Figs. 1 and 2, it will be seen that the rack of the type to which the present invention relates consists of a bottom plate I from opposite sides of which generally vertical walls 2 and 3 extend being joined at the ends of the base plate by end walls 4 and 5 respectively. The bottom plate l is preferably composed of metal or, if of wood, provided with a metal upper facing. The box-like structure so formed is supported upon a suitable base 5, the details of which form no part of the present invention, this support 5 supporting the base plate at an angle with respect to the horizontal which angle approximates 15 thereby to elevate the rear side 3 of the rack somewhat above the front 2. Frequently along the front edge 2 of the rack is a glass front panel 1 in which are display cards giving the price and other pertinent data relative to the contents of the bins. Extending upwardly from the rear side 3 of the rack may be a mirror 8 along the upper side of which is a suitably shaded source of light 9 by which the contents of the rack are illuminated. The rack just described will be recognized as a more or less standard fruit and vegetable display rack now commonly used in chain stores and the like.
As will be seen in Figs. 1-4 inclusive the boxlike rack is divided into generally rectangular pockets by the refrigerating apparatus of the present invention, such apparatus consisting of a plurality of pipes arranged in vertical rows l0, ll, 12 and 13, which rows are shown to extend from end to end of the rack. Cross connecting pipes I4 and I5 connect the individual pipes together to form a coil through which a refrigerating medium may enter through pipe' 16 and flow through the bottom ones of the pipes in each of the rows, thence to the next pipes and so on leaving the coil through the pipe l1. As shown each of the pipe rows H], ll, 12 and I3 contains four individual pipes located one above the other; this arrangement being subject to variation within the teachings of the invention.
The pipes thus forming the refrigerating coil are supported by suitable supports 20 which are preferably generally U-shaped members that extend between and abut against the sides 2 and 3 of the rack. These U-shaped members, preferably formed of metal, contain rows of perforations 2| through which the pipes project. The members 20 are disposed with the open end of the U downwardand flanges 22 are extended outwardly and rest upon the bottom or base plane I of the racl; to support the pipes thereabove.
The holes 2| are of such dimension that the supports 20 may be moved longitudinally of the pipes without difficulty.
Fitting between adjacent supports 20 and over each row of pipes therebetween, such as for example row H, is a spacer 25 composed of metal and of generally U-shaped section. This spacer 25 is of such dimension as to snugly fit over and engage the pipes in the row as shown in Fig. 3. The ends of the spacer 25 abut against adjacent onesof the supports 20, thereby fixing those supe *2 ports longitudinally of the pipes. Spacers 25 have flange-like projections 26 located at their bottom edges, which projections rest upon the flanges 22 of the supports 20 thereby spacing the spacers slightly ofi of the bottom plate I of the rack.
The number of supports will depend upon the desired dimensions of the compartments to be formed and upon the length of the rack. In Fig. 1 a few supports 20 are shown, and it will be understood that supports will be provided as required. As will be apparent, the distance between adjacent supports 20 will depend upon the length of the spacers 25 and the dimensions of the compartments or bins in the rack will likewise be so governed. By providing at the edges 2 and 3 of the rack a spacer 21 which is essentiallyjust half of the spacer 25, the pipes in run ID of the coil will be covered andthe compartment 30 will be bounded by smooth planar metallic walls capable of efiiciently transmitting heat from the produce to the refrigerating coils by conduction. Compartments! will be similarly bounded by adjacent supports 20 and adjacent spacers 25 and compartment 32 by the supports 20, the spacer 25 on the pipes in run l2 and the side spacer ad jacent the front wall 2 of the rack.
At the ends 4 and 5 of the rack cross-connecting coils l4 and I5 are covered by suitable plates which essentially consist of half the supports 20.
The compressor-condenser unit employed forms no part of the present invention as there are a number of such units available on the open market. As shown the compressor 35 is driven by a suitable motor 36, and draws refrigerant through the pipe l1 and forces it through pipe 31 into the condenser 38 where the refrigerant is liquefied and returned to the coil through pipe Hi, there being suitable control valves interposed in the customary manner.
In certain instances, such as for example, to ripen fruit that is received too green for immediate sale, it may be advantageous to apply heat -to the display rack. For such operation pipes l 6,' l| and 31 are connected so that the coil in the rack becomes the condenser and the condenser 38 becomes the evaporator.
From the foregoing it will be apparent that the refrigerating apparatus of the present invention' is capable of being installed in existing racks or in new racks of the same dimensions. The apparatus itself forms dividers that bound the individual. compartments by smooth planar metallic walls through which heat may be conducted efi'iciently. The refrigerating apparatus does not in any way interfere with the manner in which the merchandise is displayed both directly and through images reflected by the mirror. The refrigerating apparatus can be built economically without sacrificing quality and can be maintained in clean, sanitary condition without difficulty.
While I have chosen to show my invention by illustrating and describing a preferred embodiment of it, I have done so by way of example only as there are many modifications and adaptations which can be made by one skilled in the art within the teachings of the invention.
Having thus complied with the statutes and shown and described a preferred embodiment of the invention, what I consider new and desire'to have protectedby Letters Patent is pointed out in the appended claims.
