REFRIGERATOR.

Application. filed May 25,

Our invention relates to a combined refrigerator and kitchen counter more especially intended for the refrigeration of fish and especially designed for use on railroad dining cars and therefore adapted to the restricted and more or less extreme conditions encountered in the kitchen portion of the cars; the refrigerator being so constructed that it may be employed as a kitchencounter.

Our improved refrigerator is especially designed for mechanical refrigeration obtained by mechanical units of well known construction and has for its object the provision of a construction wherein proper circulation of air will be provided without, however, permitting the entrainment of moisture from the fish holding compartments into the remainder of the refrigerator and the contamination of other food products contained in the refrig erator.

The objects and advantages of our inven tion will be more readily comprehendedfrom the detailed description of the accompanying drawings, wherein- Figure 1 is a sectional elevation of our improved refrigerator and counter, with the front wall broken away.

Figure 2 is a longitudinal sectional View taken on the line 2-2 of Figure 1 looking downwardly. I

Figure 3 is a verticalsectional view taken on the line 3-3 of Figure 1 looking in the direction of the arrows.

Figure '71. is a detail sectional view taken on the line l-l of Figure 1, looking in the directi on indicated by the arrows.

Figure 5 is a detail sectional view of one corner of a fish holding tray or container and its supporting runway.

The refrigerator and kitchen counter comprises an outer wall 10 which may be of suitable wood of proper thickness, or metal, havan inner spacedwall llwhicluifmade ofwood, is preferably covered with sheet metal. The spaces intermediate of the walls at the sides,

. top and bottom are filled with suitable insulating material such as cork board, indicated at12, of suitable thickness to thoroughly insulate the refrigerator; the cork-board being preferably sealed with a non-odorant cold seal cement. The refrigerator, preferably at a central point and adjacent to the top, rovided with the mechanical refrignnit comprising the usual fluid hold.

ing container 13 with its fins and coils indicated at 14, secured in place in any suitable manner. As the refrigerating unit is of a well known construct-ion detailed description and illustration thereof need not be entered into.

Disposed transversely of the refrigerator and extending from front wall to rear wall are a pair of spaced apart bafiles or

partitions

15, 15 consisting of suitable insulating mate'- rial, such as cork board covered with sheet metal the partitions or baflles being arranged in spaced relation with the top and bottom of the refrigerator so as to provide the

air passages

16 and 17 above and below the partitions or bafiies to permit proper circulation of air. The partitions or

bafiies

15, 15 on the opposite faces and at points intermediate of the top and bottom edges thereof are provided. with the inwardly and downwardly sloping

bafile portions

18, 18, terminating adjacent to the vertical center line of the refrigerator in spaced relation to provide an air throat or passage 19 therebetween.

The bottom of the refrigerator adjacent to the partitions or baflles 15 and on what may be termed the inner sides thereof are pro vidod with suitable angle irons 20 extending transversely from front to rear of the refrigerator with the ends of the angle irons bent downwardly and secured on the bottom 21 of the refrigerator. The angle irons 20 are arranged in pairs on opposite sides of the vertical center line and therefore on opposite sides of the air passage 19. These angle irons provide suitable supports and run-ways for the fish holding trays or drawers 22 which extend from front to rear of the refrigerator. The trays are preferably of sheet metal, having bottom and'side walls and open tops;

with the forward ends thereof preferably provided with a suitable hand-grasp as at 23, see Figure 1,'to enable the trays or containers to be slid outwardly from the refrigerator when the doors 24 (see Figures 2 and 4) have been opened. The fish containers or trays 22 along the bottoms and at the sides adjacent to the bottom are preferably provided with a num- .ber of arcuate bosses or round protrusions 25, preferably of brass in order to permit the trays or containers to readily slide on the angle irons or runways 20 and to offer a small contact area with the angle irons so as to ii revent stinking of the trays to the angle irons therewith), we provide the baffle members 18' with the sheet metal spring plates or resilient strips 26 which extend from front to rear of the refrigerator. The upper ends of these strips are properly secured to the baffles 13,

while the lower free longitudinal edges are bowed or bent lnwardly as shown in Figure 1 so as to have snug sliding relation with the sides of the fish containers 22, thereby closing off communication between the space above the fish containers and the air duct or passage 19'. Vi e also provide the partitions or baffle walls 15, beneath the baffles 18, with similar sheet metal spring plates 2?, whose free lower longitudinal edges are bowed or flexed inwardly to press against the adjacent side of the fish containers and provide sliding contact. The strips 27, like strips 26, extend the full width of the refrigerator from front to rear. It is apparent that with this construction air is practicall prevented from circulating around the fish containers and as a result contamination of the other food prod ucts prevented.

, The partitions'or walls 15 at suitable points intermediate of the tops and bottoms are shown provided with suitable angles 28 and with inwardly disposed lips 29 at the bottoms to provide rests for the shelves 30. The shelves 30 are shown consisting of suitable mesh screen preferably bound in a metal frame for reenforcement and to permit the shelves to he slid in and out on the

ledges

28 and 29; the opposite sides of the shelves 30 being supported by the

angle strips

31,31 secured to the side wall of the refrigerator. These shelves preferably extend from front to rear of the refrigerator, as shown in Figure 2, providing food-holding compartments made accessible by suitable doors as at 32, see. Fig ures 2 and 3, which'may be hinged as at 33 to swing toward one side. The doors, like the walls of the refrigerator, preferably consist of wood or metal and suitable insulating material or cork board as shown at 32 in Figures 2 and 3, and adapted to fit into the arranged to provide a somewhat larger passage 16 at top than, the s ze of passage 17 at the bottom thereof in order to inducearapid circulation of air.

- WVith the construction shown, the cold air from the refrigerant-holding compartment drops or passes downwardly through the passage1'9 toward the bottom of the refrigerator along the adjacent sides of the fish containers or trays 22, arranged on each side of passage 19, and beneath the bottoms thereof toward the opposite ends of the combined refrigerator and counter. As the shelves 3-0 are of wire mesh or suitable foraminated material, the air is permitted to rise toward the top of the refrigerator and caused to pass through the passageways 16 into the refrigerant holding compartment where is is again chilled and caused to drop down through passage 19; a constant rapid circulation of air being thus brought about. it is apparent from the construction shown in Figure 1 that the cold air merely passes about two sides of the fish containers, namely tlieside walls disposed toward the cold air duct 19 and the bottoms and is not permitted to pass along the sine of the fish containers disposed adjacent partitions 15 because of the closure strips 26 and 27.

In practice, we prefer to provide a separate closure or door for the refrigerant-l'iolding compartment, which may be formed in sections as disclosed in dotted lines in Figure l with the two side sections 35 preferably secured in place by suitable screws, while the intermediate section 36 may be liingedl'y se cured in place to permit ordinary inspection of the refrigerating unit. The sections 35 may be readily removed with the intermediate section 36 in the event it is found necessary to remove or replace the refrigerating unit. It is evident that instead of employing a single door for each pair of food-holding compartments formed by the shelves 30, separate door sections may be employed and other minor details of construction altered without, however, departing from the spirit of our invention, which has been described in terms employed merely as terms of description and not as terms of limitation.
