In the embodiment of the invention selected for purposes of illustration, there is disposed within a heat insulated provision compartment of»-a re 30 frigerating apparatus, a cooling means or evapo rator, disposed adjacent the top thereof and di vidin‘g the space betweenvthe side walls at -the upper portion of the provision compartment >into two spaces preferably of unequal. size, with a 35, shelf extending transversely of the provision com partment below the cooling means and arranged to support a defrosting tray immediately below the cooling means and ymovable shelves or baskets upon each side of the cooling means, all of the 40 shelving being constructed and arranged so as to permit a substantially unimpaired circulation of air within the provision compartment and in heat exchange relationship with the cooling means and whatever provisions may be disposed upon 45 said shelves. ' . f For a better understanding of the invention, reference may be had to the following specifica tion taken in conjunction with the accompany ing drawings of which there are four sheets, and 50 wherein: _ > Fig. 1 is a front elevational view of the upper portion of a heat insulated provision compart ment provided with cooling means internally thereof and illustrating the relative disposition 55 of the shelves, baskets and defrosting tray with respect to the cooling means, the door of the pro the line II--ll thereof; , Fig. 12 is a vertical sectional vie'w of a4 por tion of the shelfbasket illustrated in Fig. 10, and 25 illustrating a detail thereof and taken on theline l2-I2 of Fig. 11; ` _ Fig. 13 is a perspective view of another form of shelf basket and which is adapted -to be sup ported upon the shelf illustrated in Fig. 3, and 30 to be disposed upon that side of the‘cooling means , opposite that on which the shelf> basket illus trated in Fig. 10 is disposed; Fig. 14 is a horizontal sectional view of a por- - tion of the shelf basket illustrated in Fig. 13, and 35 taken along the line I4-I4 thereof; _ Fig. 15 is a rear elevation of the lower portion of the shelf basket illustrated in Fig. 13, and taken along the line I5-l5 of Fig. 14; Fig. 16 is a side elevational view illustrating 40 a‘modiñed form of the shelf basket illustrated in Fig. 10; _ Fig. 17 is a horizontal sectional view of the bot tom of the modiñed form of shelf basket illustrat 45 ed inFig. 16; and Fig. 18 is a perspective view of the removable bottom portion of the modified form of- shelf basket illustrated in Figs. 16 and 17. Referring now to Figs. 1 and 2 of the drawings, there is illustrated a portion of a refrigerating 50 apparatus of the domestic _type provided with a heat insulated provision compartment 20, the compartment being provided _with a relatively large opening through which access may be ‘had’ thereto and which opening is adapted to be 55 closed by a door 22. The heat insulated provision Icompartment 20 may be provided 'with a cooling vision compartment being in part broken away; . Fig. 2 is a vertical section through the lower i' means, indicated generally 'at 24, and disposed _ portion of vthe provision compartment and illus GQ trating in elevation one of the shelf baskets in one within the upper portion of the compartment 2_0, spaced `from the side walls thereof, and exposed als/1,106 2 to the air within the compartment 28 so that the air may circulate in heat exchange relationship therewith. The cooling means or evaporator 24 is adapted to absorb the heat from the provision compartment 2D and may comprise a portion of a conventional refrigerating system of the compressor, condenser, expander type. The evaporator 24 preferably is provided internally The shelves 40 and the shelving means within the lower portion of the provision compartment also may be supported by pins carried by the side walls of the provision compartment, and in the case of the shelves 40, also by pins carried by the side of the evaporator 24. As illustrated in Fig . 7, 8 and 9, the wires 58, which extend between the front and rear portions of the main frame mem thereof .with a freezer compartment through 10 which access may be had through the door 26, with a manually operated switch 28 which con trols the operation of the compressor driving means, and with an adjustable control switch 30 which is adapted automatically to control the ber of the shelf 32, may be curled around the outside edge of the frame member as illustrated at 56 and welded or otherwise secured thereto. This construction provides a smooth finished ex terior surface for the shelf, provides a better joint between the main frame of the shelf and the shelf 15 operation of the refrigerating system for main wires thereof, and eliminates exposed sharp or 15 jagged edges which would make the shelf diñicult to handle and clean. The wires 50, the guides 42 and 44, the rails 46 and the reinforcing frame member 48 ‘may be secured together by welding taining the temperature within the rprovision compartment within desired limits. In addition to the shelving means disposed within the bottom portion of the heat insulated 20 compartment 20, there is provided a shelf 32, extending transversely of the provision compart ment and spaced below the bottom of the Vevap orator 24, so as to accommodate upon the shelf 32, a defrosting tray 34 below the evaporator 24 25 for receiving the drip therefrom, such as occurs when the evaporator is being defrosted. The shelf 32 is also arranged to support upon the upper side thereof and between the evaporator and the sides of the provision compartment, a pair 30 of removable shelves or baskets 36 and 38. The . space above the basket 36 may be divided by a pair of shelves 48 which extend between the side walls of the provision compartment and the evap orator 24, while the space above the basket 38, preferably is left unobstructed so as to provide a space along side of the evaporator 24 particularly designed for the storage of bottles in an upright condition. The baskets 36 and 38, the shelves 4l) and 32, and the shelving means within the 40 lower portion of the provision compartment pref erably are formed, of Wire so as to permit the free and substantially unimpaired circulation of air within the provision compartment, it being under stood that air within the compartment circulates in heat exchange relationship with the evapora tor 24 and with the food stuffs and other ma terials disposed within the compartment, and it is essential if adequate refrigeration is to be pro vided within the entire compartment, that no 50 impediment be offered to the circulation of air . Within the provision compartment 28. The shelf 32 comprises, referring to Figs. 3 through 9, a rectangular frame of relatively heavy wire, bridged at one end by a pair of guides 42 55 which are adapted to slidingly or niovably sup port the basket 36, and at the opposite end by a second pair of guides 44 upon which the basket 38 is adapted to be supported for sliding move ment, a pair of rails 46 which are adapted to 60 support the basket 38 against tipping,> a reinforc ing frame member 48 extending between one of the rails 46 and .an opposite portion of the heavy rectangular frame of the shelf 32, and a series of relatively> light wires 50 extending be tween the front and rear portions of the rec tangular frame member of the shelf 32 and be tween the guides 42 and the guides 44 and upon or soldering or in any other suitable manner. the elevation of the shelf 32. The defrosting tray 34, at the back thereof, may be provided with 25 a recess portion 60 complementary to the shape of the light bulb 58 and for accommodating the same. The basket 38, as appearing in Figs. 13, 14 and 15, which is adapted to be movably supported 30. upon the right hand end of the shelf 32, looking at Fig. 1, is provided with a bottom shelf portion 62 and an upper shelf portion 64, the bottom shelf portion being enclosed except for an opening im mediately below the shelf portion 64 on the 35 evaporator side of the basket 38, and thel upper shelf portion being provided with a guard portion 66 extending therearound so as to prevent the accidental displacement from the shelf portion 64 of bottles which may be supported thereon 40 during movement of the basket 38 into and out of the provision compartment. . The basket 38, as illustrated,lis formed of a bottom frame member 68, apair of side frame members 18 joined to the bottom frame member 45 68 at the front and rear thereof, a plurality of vertical frame members 12 connectingl horizon tally disposed portions of the side frame members 'l0 with the bottom frame member 68, a plurality of horizontally disposed reinforcing frame mem 50 bers 'I4 connecting the side frame members 10, the vertical frame members 12 and opposite por tions of the bottom framemember 68, and a handle 'I6 connecting opposite vertically disposed portions of the side frame members 10 at the 55 front thereof. A series of relatively small wires T8 are secured to the horizontal frame members 14 and the bottom frame member 68 for enclos ing the front, bottom and rear of the basket 38, the horizontally disposed portion of the series of 60 wires 18 forming _the shelfrportion 62. A plu rality of horizontally disposed wires 80 are se cured to the frame members 12 and 10 for clos ing in the sides of the basket 38 except for the opening which lis provided on the evaporator side of the basket 38 immediately below the shelf which shelf portion, provided by the series of wire portion 64. The shelf portion 64 is formed by a ' series of wires which are secured to certain of 50, the defrosting tray 34 is adapted to be sup the horizontally disposed cross frame members ported, the outside wires of the series of wires 50 74, and which cross frame members are disposed at an elevation substantially below that of the horizontally disposed portion of the side frame members 10. being formed >`to providel guides 52 for guiding the defrosting tray. , The side walls of the provision compartment may be provided with any suitable means, such as pins 54 upon which the shelf 32 is supported. , 20 A light 58, again referring to Figs. 1 and 2, is provided Within the compartment 28 and sup ported adjacent the rear wall thereof just above The longest sides of the frame member 68 are v v adapted to be slidingly supported by ¿ the guides 3 2,184,106 44 so as to permit movement of the basket'38 from a position immediately above the shelf to a position where a major portion thereof will over hang the front of the shelf and project through the opening of the food storage compartment so that provisions may be removed from the shelf portions 62 and 64 of the carriage 38, access to . the shelf portion 62 being provided through an ., opening in the evaporator side thereof. The 10 frame member 68, at the rear thereof, is provided with a guide member 82 secured to the under side thereof, the laterally extending portions of which , are adapted to engage the underside of the rails 46 for securing the carriage 38 against tipping 15 when the same is moved forwardly on the shelf 32. The rails 46, at'the rear thereof, are spaced far apart so as to permit the engagement of the about the front of the shelf as a pivot and the forward bottom portion of the basket 36 may be rested .upon 'the outside of the throat lining of the provision door opening. As the top of the shelf basket 36 is open, access may be readily had to the various sub-compartments therein, it being observed that the partitions between these various sub-compartments, formed by the series of wires |00, and at such time as the shelf basket 36 is disposed in the position illustrated in Fig. 2, act 10 as shelves, one arranged substantially above the other. Th'e flat transverse frame members 90, extending between the side frame members 88 at the top of the shelf basket 36, form a rail or fence across the front of the partitions at such time as the shelf basket 36 is disposed in a posi tion such as that illustrated in Fig. 2, for pre venting the accidental displacement of any pro guide member 82 wit-h the under side of the rails 46, and a stop member 84 is secured to the rails í. visions contained Within the sub-compartments 20 46 adjacent the front thereof for limiting the in the shelf’basket 36. The shelf basket-36 is 20 forward movement of the carriage 38. substantially` of a depth equal to the distance be In Figs. 10, 11 and 12, there is illustrated tween the shelf 32 and the next adjacent shelf 40 another form of shelf basket, somewhat like the thereabove, and it may readily be observed that one illustrated in Fig. 15, and which shelf bas the shelf basket 36 provides a container by means ket is adapted to be supported upon the shelf of which a very efficient utilization of the space 32 on the left hand side of the evaporator 24, between such shelves may be had as well as looking at Fig. 1. The shelf -basket 36 is of wire making it extremely convenient to obtain access construction like the shelf basket 38 and com to anything stored in any of the sub-compart prises a relatively heavy wire bottom rectangular ments of the shelf basket 36. In Figs. 16, 17 and 18, there is illustrated a. 30 30 frame member 86, a pair of side frame members 88, a plurality of cross' frame members 90 con necting oppositely disposed portions of the side frame members 88 and the bottom frame mem ber 86, one of the frame members 90 at the front 35 of the shelf basket 36, being formed to provide a hand grip 92, a plurality of vertically disposed frame members 94 connecting the sidey frame members 88 with some of the cross frame mem bers 90, a series of vwires 96 secured to some of 40 the cross frame members 90 and covering the front and bottom of the shelf basket 36 and por tions of the top and rear thereof, other series 98 of wires enclosing the opposite sides of the basket 36 and secured to the vertical frame members 04 and to the front and rear vertically disposed por 45 tions of the side frame members 88, and another series »|00 of wires extending transversely of the basket 36 for dividing the same into a plurality of compartments and secured to certain of the ver tical frame members 94. The baskets 36 and also 38, it will be observed, are thus constructed en tirely of wire suitably secured together, such as by a spot welding or soldering which provides strong rigid baskets fcï supporting provisions, and through which baskets the circulating air 55 within the provision compartment may freely pass. ' » modiñed form of construction for the shelf bas ket 36 wherein the bottom of the shelf basket is made so as to be separable from the remaining portion of the shelf basket. In this modification, a substantially rectangularly shaped shelf sec 35 tion |06 is provided, and which section |06 is adapted to be supported in the guideways 42 so as to form with the remainder of the shelf 32, a shelf construction wherein portions thereof dis posed at the same elevation are relatively mov 40 able. The shelf section |06 is provided with a pair of members |02 which are adapted to en gage the transversely extending portion of the frame member of the shelf 32 at the front there of so as to limit the forward movement of the shelf section |06. . ' The upper portion of this modified form of shelf basket construction is generally like the constructionlof the shelf basket 36 except that the upper portion, indicate'd‘generally at |08, is 50 provided with an independent frame so as to be structurally rigid when independent of the shelf section |06. The upper portion |08 is provided with a pair of hooks ||0 spaced apart a'nd at thel rear thereof for engaging the back of the frame of the shelf section |06, andthe front portion of' the upper section |08 is provided with a pair The side portions of the bottom frame member ~ of spring clips ||2, which are adapted to snap 86 are adapted to be engaged by the guides 42 for supporting the basket 36 for sliding move 60 ment. The portion of the bottom frame mem ber 86, extending across the rear of the basket 36, is provided with a pair of spaced brackets |02 winch serve as a stop for limiting the forward movement of the basket 36 relative to the shelf over the front portion of the shelf section |06 and thereby secure the upper portion |08 to the 60 shelf section |06, so that when the parts are thus assembled,- they will be substantially like the shelf basket 36 and may be used in exactly the same way. The principal object of providing the portion of the main frame >member of the shelf 32 between the pins |04, which pins |04 serve removable upper portion |08 is to permit the shelf section |06 to be used independently when the basket feature is not desired. In this in stance, the handle ||4 may be provided on the to prevent lateral shifting of the basket 36 when shelf section |06. by engaging the> transversely extending front the members |02 are engaged with the front por 70 tion of the frame member4 of the shelf 32, because at this time, the side portions of the frame mem ber 86 of the basket 36 have been moved for wardly-out of engagement with the guides 42. 75 The basket 36n may then be tipped downwardly v , The shelf 32, it will be observed, supports in 70 addition to the defrosting tray 34, the shelf bas kets 36 and 38. The shelf basket 38, in addition to providing a movable carriage or support for relatively tall objects, such as bottles, provides below the bottle support, a storage 'place for 75 9,134,106 4 various small sized provisions, and because of the movability of the shelf basket 38, access may readily be had to anything stored within the bas ket 38. The open work construction of the shelf baskets 36 and 3B does not impede the free cir culation of air within the provision compartment and enables such circulating air to pass in heat exchange relationship with anything disposed 10 within such basket 36 or 38. While the invention has been described with some detail, it is to be understood that the de scription is for the purpose of illustration only and is not definitive of the limits of the inventive idea.
