An object of the invention is to provide a refrigerator of generally improved construction.
Another object of the invention is to provide a refrigerator designed to retain perishable commodities in well-preserved condition for relatively long periods of time.
A further object of the invention is to provide a refrigerator constructed so that it may be readily kept in clean, sanitary condition.
Still another object of the invention is the provision of a refrigerator having a case structure designed so as to enable convenient access to the interior thereof and emcient closure.
A still further object of the invention is the provision of a refrigerator of the aforesaid character embodying a compact case structure having a display as well as a storage compartment.
Still another object envisages a refrigerator of the character described which is especially adaptable to modern practice of so-called selfservice."
Other objects and advantages of the invention will become apparent as the description progresses. t

Figure 8 is a partial view of the same showing details of construction,
Figure 9 is a view similar to Fig. 3 but showing said modified version, 4
Figure 10 is a fragmentary transverse section showing the drip-pan supporting structure, and
Figure 11 is yet another modified form of the upper compartment of the refrigerator, seen in transverse sectional view.
Referring to the drawings, whereinfor the purpose of illustration is' shown a preferred embodiment of the invention, 0" designates the refrigerator case in its entirety, the case preferably being in the form of a rectangular elongated structure. At each end of the case is provided a vertical wall l5, which maybe formed of wood covered with sheet metal or any preferred insulating construction. At the top portion, the front side edge of the end walls l5 are inclined toward the top as shown to advantage at Figure 2. The rear, or back, edge of said walls are straight since the refrigerator is intended to be used against a wall. The back wall I6 carriesa shelf S adjustably supported onto vertical standards secured to said wall, for display purposes.
At the front of the case is provided a bottom vertical frame section 20 provided with a plurality of rectangular door openings and to which are connected, through the medium of hinges 2|, a plurality of horizontally swinging doors 22 which may be fastened in tightly closed position by suitable latches or fasteners 23. The upper section of the front wall is in the form of a frame structure 25 providing a pair of elongated door openings. The inner edge of this frame structure, particularly the top and bottom rails, is rabbeted to form relatively narrow inwardly protruding uide strips 26. These strips serve to support a pair of inner door members 21 having straight exterior edges and disposed to fit within the grooves of the inclined frame. co-operate with complementary outer doors 28 to provide closures for the frame openings, the edges of the doors 28 being rabbeted to form exterior guide strips 29 designed to project so as to extend over the outer edge portions of the frame, as shown to advantage at Figures 3, 6 and 7. The complementary doors 21 and 28 preferably embody rectangular shaped wooden frames within which are fitted spaced panes of glass 30 and are constructed so that the inner doors, resting on the frame strips 26, will slidably fit within the grooved edge of the frame, between the strips 26 and the exterior doors 28, so that the complementary doors may be slidably actuated one over the other and are readily removable in any position by merely lifting the same from the framestructure, having in mind that these doors retain their position on the inclined frame by gravity.
The bottom 32 of the case is preferably supported on frame bars 33 so that it will assume a position above the floor. The top of the case, indicated at 34, is relatively narrow, in accord-' ance with the inclined upper side structure, and
These doors is preferably constructed so as to provide a forward protruding curved hood 35 containing lighting means, as for instance electric lamp 36, disposed exteriorly of an adapted. together with the inside lamp 38. to illuminate the interior of the case. Immediately below the top member 34 is provided a perforated interior top plate 31.
To the bottom section 20 of the front wall are connected a plurality of angular brackets 46 disposed at longitudinally spaced positions at the juncture of the top and bottom sections. The vertical leg of each bracket 40 is secured by screws that emcient air circulation and ventilation is provided in the case.
The form of the invention shown in Figs. '7'-89 embodies most of the elements described above, to the exception of the sliding doors 21-28 which are replaced by a glass pane 65 extending completely across the upper part of the compartor other fastening means to the wall structure,
while the opposite leg is disposed to project laterally thereof, as illustrated at Figures 35-9. 0n the inner portions of the set of brackets '40 is secured an elongated strip 42 extending approximately the full length of the case and having connected thereto, through the medium of hinges 43, a plurality of shelf sections 44. These shelves are disposed so that they may be swung to upward, out of the way positions, or to outward horizontal laterally projecting positions, as shown to advantage at Figure 9.
Within the upper portion of the case C is supported a cooling coil 46 preferably arranged so that the component sections extend approximately the full length of the case and are disposed in two superposed horizontal rows of four each, as shown at Figure 3. A second cooling coil 41 is arranged in the intermediate portion of the case, approximately midway between the top and bottom, and is composed of pipe sections extending approximately the full length of the interior of the case and arranged in a horizontal row which may consist of approximately nine sections. These cooling coils 46 and 41 connect with a supply pipe 48 and with a return pipe (not shown) these pipes extending vertically adjacent one end wall for connection with a refrigerating machine exteriorly of the case.
Above the cooling coil 41 is supported a horizontal partition 52 formed of sheet metal or the like and provided with a plurality of relatively small apertures 53. This partition extends lengthwise in the case and is supported by longitudinally extending strips 54 secured in the case and divides the interior chamber into a bottom storage compartment 55 and an upper display compartment 56.
Disposed immediately below the coil 41. so as to catch the drippings therefrom, is an elongated drip-pun 58 hinged at 6I to the rear wall I6 and supported horizontally in position by means of a plurality of bolts, or the like, 59 engaging the front frame 20. As shown to advantage at Figures 3,v 4-9 the pan is connected by a rubber hose an to a drain so that the pan 58 may be readily inclined toward the bottom 32 for frequent convenient cleaning to retain the same in sanitary condition.
Just above the sheet partition 52 is mounted an open-mesh partition 62, formed of wire or the like, arranged in an approximately horizontal position extending across and the ful1 length of the case to form a support for the commodities in the upper display compartment 56, yet permitt-ing eflicient circulation of air therethrough.
As will be'noted from Figures 3, 8, 9 and 11, ventilating ducts 64 are formed at spaced intervals through the top rail of the frame section 25, affording communication between the upper zone, divided from the display compartment by the perforated partition 31. and the exterior so meat 56 for approximately one half the height thereof. Thus, a space is left below the lower edge of said glass pane, free of obstructions, through which the goods displayed on the partition 62 are readily available. This form of the invention is especially desirable in those so-called self-service" stores, where the customer is expected to select and pick his own merchandise himself from conspicuous and strategically disposed counters. The constantly open spece below the glass plate is adapted to be closed, at night, by swinging upwardly the shelves 43, as shown in Fig. 9.
The other modified form of Fig. 11 is similar to that of Fig. 3, with the difference that the back wall I6 embodies a display panel at the top and now forms the front of the case. This panel is inclined and is supported in a frame section Il embodying double panes of glass I6.
This construction provides a refrigerator case of compact, highly efficient design, affording a maximum storage and display space as well as convenient accessibility to these compartments. The removable doors in the upper rear wall section enable convenient insertion or removal of relatively large commodities and also enable convenient cleaning. The cooling coils are disposed to preserve the contents with utmost efliciency.
It is to be understood that the forms of my invention herein shown and described are to be taken as preferred examples of the same, and that various changes as to the shape, size and arrangement of parts may be resorted to without departing from the spirit of the invention or the scope of the subjoined claims.
