HEATING AND DISPLAYING CABINET Filed March 12, 1952 4 Sheets-Sheet 4 ll W ATTORNEY 4 Patented Oct. 22, 1935 :EUNITED STATES PATENT OFFICE My invention relates to cabinets especially adapted for the attractive display and suitable heating of commodities. v

It is frequently desirable to maintain com- Q modities, such as nuts, pastry and others, dn a heated condition while being exposed for sale and as many commodities are deteriorated by long exposure to a temperature as great as that which they should attain at the time of sale 30 and consumption, it is most advantageous that the reserve stock exposed for sale should be retained at a temperature below that of those commodities at the time of sale.

The device of my invention accomplishes the 13 above and other desirable conditions and presents a means whereby commodities may be attractively exposed for sale and in which the commodities may be subjected to temperatures necessary for the best retention of their propm erties.

In the accompanying drawings illustrating one form of the device of my invention, similar parts are designated by similar numerals.

Figure 1 is a perspective view of one form of :5 a device of my invention.

Figure 2 is a section through the line 22 of Figure 1.

Figure 3 is a top view of the upper portion of the-device of Figure 2.

a urFigure 4 is a front view of the device of Fig- Figure 5 is a rear view of the device of Figure The particular form of the device of my ina vention illustrated in the accompanying drawings consists of two casing side members and II having the extended members l2 and 13, the latter members allowing of a space behind the device for the storage of commodities upon the 40 counter, or table, upon which the device rests.

A back casing m'ember l4 extends upwardly from the bottom member and supports a removable downwardly and forwardly tray consisting of the bottom, or'fioor, 16, the sides l1, l8. l3, and 20, the latter resting upon the bottom member 15. Guide plates 21, 2|, spaced from the upper faces of the sides l8 and i9 allow of the slidable removal of the glass plate 22. The bot- 50 tom 16 of this commodity tray has a plurality of

recesses

23, 23, the recesses extending into the sides l1 and 20, thus allowing the placement of

partitions

24, 24, as desired. The entire commodity tray can be displaced and removed by 55 inserting a finger, or other suitable device through the hole 25,111 the bottom member l5 and moving it upwardly.

Guide plates

26, 26, carried by, and spaced from, the upper faces of the sides Ill and H allow of the slidable removal of the downwardly 5 and forwardly inclined glass plate 21. The upper portion 28 of the glass plate 21 is translucent and has letters 29, 29 printed, or painted, thereon for purposes described later.

The warming element of the device. is con- 10 structed as foliows:

A perforated metal bottom plate 30 has the upturned sides 3|, 3i and a perforated metal top plate 32 has the downwardly turned

sides

33, 33. The

opposite side portions

35, 35 of the 15 top' plate 32 extend outwardly to rest upon the

extended supports

34, 34, fixedly attached to the side members l0 and l I. Supporting strips 36. 36 extend along two sides of the heating element.

A plurality of

metal strips

31, 31 extend transversely of the heating element and are separated from the bottom 30 and the top 32 by means of sheets of

asbestos

38, 38 The elements of the device are held in unity construction by the

screws

39, 39. Lateral movement of the heating unit is prevented by screws 40, 43 passing through holes in the extended

members

35, 35 of the top 32 and threaded within holes within the

supports

34, 34. 7

Within the casing constructed as above described are a number of electric devices 4i, 4| of any well known suitable construction, such as heaters of the type commonly known as strip heaters. As adequate for my invention, these heating devices are shown in the drawings simply as a seriesof horizontallyzspaced horizontally extending flattened tubular members. These heater members 4!, 4|, are spaced below the top plate 32 and are spaced above the bottom plate 30. Thus air may pass freely upwardly, through 40 the perforated bottom plate 30, around the heat er members 4|, 41, by which it is heated, and through the perforated top plate 32. As speciflc means necessary for the electrical heating of my device is not a part of my invention, and

as it may be greatly varied, I simply describe it as being accomplished through the medium of the

electric conduit wires

42, 42 within the cable 43, controlled by a switch 44.

A plurality of

rods

45, 45 are removably carried bythe sides i 2 and 13.

Electric light bulbs

46, 46 are positioned below the heating element and behind the translucent portion 28 of the glass plate 21.

It will be noted that commodities placed in 5a the commodity tray can not be removed without removing the

glass plates

22 and 21, the upper portion of the device is not thus protected,

and hence commodities placed between or upon the rods 45, are capable of ready removal.

The operation of the device is as follows, assuming that nuts are the commodities displayed:

Loose nuts of various kinds, or bags thereof, are placed in the several compartments of the commodity tray and the glass covers 22 and 21 placed in position as shown. Bags of the nuts are placed upon the top plate 32, between the

rods

45, 45, and also may be placed upon these rods, or any other suitable support. The heaters 4|, 4| are then placed into operation and the

electric light bulbs

46, 46 illuminated, by means of the switch 41.

It will be noted that, because of the construc tion of my device, the bagged nuts between and upon the

rods

45, 45 will be heated considerably higher than those in the commodity tray, a condition of great importance as the continuous high heating of the nuts in the commodity tray prior to disposal will greatly injure their properties, while at the same time it is desirable to have them in heated condition when dispensed.

The letters and words 29, 29 will be made attractively visible through the medium of the elec tric light bulbs 4, 46.

My device, therefore, presents a means whereby commodities may be attractively exposed for --sale, while being desirably heated without undue iniury.

I do not limit myself'to the particular size, shape, number, arrangement or character of the elements of my device as specifically shown and described as these are given simply as a means for clearly describing the device of my invention.
