DISPLAY CABINET Filed March 1l, 1938 3 Sheets-Sheet '3 Patented Dec. 24, 1940 UNITED. STATES PATENT OFFICE Reuben E. Ottcnhcimer, Baltimore, Md. Application Ml'h 11, 1938, Serial N0. 195,396 7 Ultimi. (Cl. 40-130) The present invention relates to display cabinets.
More particularly, the invention relates to cabinets of the display window type provided with sign bearing means substantially adjacent to but not obstructing the goods on display so ,that in a single glance the customer may coordinate the goods with its price and/or other information relating thereto.
10 In refrigerated display cabinets heretofore proposed, the identincation and price marking of goods on display have not been provided for in an adequate manner nor has there been any coordination of the goods with such data. In many cases price tags have been attached to the goods by pins, clips or other fastening means at the expense of the appearance of*` the display, and such devices not'only obstruct the goods but often become separated therefrom or turned at such an angle that it is dimcult for a customer to read them. In other cases. paper or similar signs have been pasted or crudely suspended upon various portions of a display cabinet, producing' an arrangement which is not onlyunsightly, but difllcult to replace when the goods to be vended is changed or when the prices themselves are. revised. Nor is it uncommon for signsrelating to goods on display to be mounted at such distances from the merchandise that a customer will find them only with aimculty if at au.
By the present invention it is proposed to provide a refrigerated display cabinet having a sign supporting surface substantially adjacent the display window in such a manner that the articles on display as well as the' signs supported on the a panel are below the eye level of an adultpf average height standing adjacent to the cabinet. In
this manner, the customer can inspect the goods on display and without unduly shifting his eyes,`
read the infomation regarding the nature of the products and their sale prices.
A highly satisfactory construction isafforded by a display. compartment having a sloping floor and a osloping multi-glazedwindow so that a customer will readily observe the contents. The
sign supportingsurface may be parallel to or angularly disposed to the window, but in any event, suiilciently -near the window to 'permit' ready scrutinyby a prospective customer survey- 50 metile goods.
It is also contemplated to provide illuminating means for the display compartment and the sign supporting surface so'as to render the goods and the information relating thereto clearly percep- 55 tible and attractive. Since in most cases the goods yat this stage of Iextremely low temperatures necessary on display in such a cabinet will be maintained at a subatmospheric temperature, provision has been made for thermally insulating the source or sources of light from the refrigerated section or sections of the cabinet. This has been accomplished by mounting the illuminating means externally of the refrigerated portion or portions 'of the cabinet, although in some cases, the i1- luminating means may be set into the cabinet so as not to project therefrom, in accordance with l0 so called flush construction.
The cabinet of the present invention may comprise a refrigerated storage compartment in addition to the refrigerated display compartment and provision has been made for maintaining such '15 compartments at different subatmospheric temperatures where desired or required by the character of the goods stored and on display. Moreover, an unrefrlgerated storage compartment has been provided, suitable for the reception of wrapping materials or other accessories 4commonly utilized in vending foods. The'refrigerated storage compartment may be provided with suitable sliding racks. shelves or trays to facilitate access by the vendor to the goods contained therein. Where itis desired to illuminate the storage compartment aswell as the display compartment and the sign supporting surface, a light transmitting panel may be used to partition the display compartment from the storage compartment so that a portion of the light may pass from the display section into the storage portion of the cabinet andthereby assist the sales person in locating desired material. The construction contemplated by the present invention is particularly adapted for use in the vending of frosted or frozen foodsl which have only relatively recently made their appearance on the market. Inasmuchas the nature, appearance, shapes, unit sizes and prices of such 40 /foods are entirely novel to the average consumer their development, it is essential that they be merchandized in such a way as to instruct prospective customers in each of these respects. Where the ordinary vehicles of ad-I vertising exclusively relied upon for thus edut eating the public, the length of time required would be dar too excessive and the expenses involved would be proportionately large. The cabinet arrangement proposed herein renders it feasible to actually display a reasonable number of examples of the actual packages for sale while maintaining the products at the comparatively for their preservation. Moreover, and of primary impor- 8096s contained in tance in this connection, the customer can inspect the food, unobscured by price ta-gs or other signs, and at the same instant observe the closely adjacent information regarding price, quality and other identifying and explanatory information concerning the novel products.
It will be evident, of course that the present construction is likewise entirely suitable for the vending of well known products such as ice cream in packages orin bulk, meats, vegetables, dairy products, etc., packed in their well known manner, but in these cases, the customer is already familiar with the appearance, condition and approximate prices of the goods. need for the present invention -is greatly intensifiedwhere, asin the case of frozen foods, the goods to be vended must first be made familiar to the public.
Inasmuch as it is preferable to present only examples of such products for actual display, it becomes important to amply provide for the storage of large numbers of diiferentkinds of the frozen foods and to furnish a source of illumination externally of the storage compartment so as vnot to reduce the effects of the refrigeration.
The illuminating means may be provided with suitable reflectors, screens, and/or other means to obtain colored or otherwise varied lighting effects. The light maybe thrown directly upon the sign supporting surface and the sign elements mounted thereon, or a translucent or transparent construction may be adopted to permit the light to pass from behind suitably constructed sign elements. Provision for Ventilating the cabinet illuminating Ameans may be provided to prevent undue heating losses and to avoid objectionable condensation.
The cabinets of the present invention are preferably of such overall dimensions that an adult sales person of average height can transact .business with the customer over the top of the cabinet so that it simultaneously serves as a counterand therefore it i-s advantageous to provide the cabinet with a fiat upper surface.
'The details of construction proposed by way of example will be evident upon reference to the attached drawings wherein:
Fig. 1 is a perspective of an illuminated cabinet having a display compartment and sign supporting panel;
Fig. 2 is a transverse section through an intermediate portion of the cabinet of Fig. l;
Fig. 3 is a fragmentary enlargement of a portion of the section of Fig. 2; I

or panel 28, a sloping rear frame 30 and a substantially flat top 3 2.
The sloping front wall is provided with a multiglazed window 34 permitting in-spection of the the display compartment I6, and adjacent to this window, one or more sign supporting surfaces or panels 38 adapted for'the reception of sign elements 40. Intermediate the window and the sign supporting surface or surfaces, there are provided as shown in Figs. 1, 2, 3 and 7, one or more lamp housings 4-2 for the reception of one or more light sources 44. The housing or housings serve to shield direct rays Accordingly, the
supplied with operating current through suitable conductors, not shown.
The display compartment 36 is separated from the remainder of the cabinet by a partition 48 which .constitutes the floor of the compartment and a partition 50 which is preferably of light transmitting material. The light transmitting partition is preferably supported in movable relationship with respect to the floor, as by means of a hinge or hinges 52. A knob or handle 54 is also provided `to facilitate adjustment of the partition for access to the display compartment. A frame 56 engages thepartition 50 when in the closed position depicted in Fig. 2 of the drawings in a manner -to substantially isolate the display compartment from the remainder of the cabinet and air'currents are thus restricted. The display compartment may be provided with a refrigerating element 58 suitably mounted in a recess 80 formed in the upper portion of the cabinet and substantially out of the line of vision of the customer.
An unrefrigerated storage compartment 62 has been shown in Fig. 2 of the drawings directly be'- hind the sign supporting surface 38 and immediately below the top 32 of the cabinet. This compartment will serve admirably for the storage of wrapping material, literature. or other accessories commonly needed in conjunction with the sale of food products.
Since the display compartment will ordinarily accommodate onlya few of the products to be vended from a cabinet of this type, a comparatively large refrigerated storage compartment 64 may be formed below the display compartment and separated therefrom by the oor 48 and light transmitting partition 58. 'This storage compartment is provided with a refrigerating element or elements 66 which may partially or completely encompass it, depending upon the refrigerating condition-s to be satisfied. To f acilitatcaccess to 4the articles stored within this compartment, its walls have been provided with a plurality of rows of tracks 68 for the reception of a similar number of rows of sliding or wheeled racks, trays or recep-v sale, and may or need not be equipped with sliding' containers.
The sloping rear frame 30 of the cabinet is fitted with one or more doors 'I2 mounted near the upper portion thereof, which may be opened for access to either or 'both lthe display compartment and the refrigerated storage compartment. The sloping relationship and the position of such door or doors with respect to the cabinet have 75 f cessibility poor.
been adopted to produce an optimum balance between accessibility and refrigeration losses. Where such doors are hung vertically, greater accessibility to the display compartment and refrigerated storage compartment might be possible, but in view of the relatively low temperature maintained within the cabinet, especially when used for frozen foods, the refrigeration losses upon opening the door would be excessive. On the other hand, were the doors suspended horizontally at the top of the cabinet the refrigeration losses would be nominal but the ac- By virtue of the position of 12 of the presentninvention, and because of the preferred relatively low height of the entire cabinet, a sales person can readily reach through the opened door to the most remote portion of either the dislay compartment, after moving the partition 50, or the refrigerated storage compartment. Moreover, since .the entire cabinet is preferably below the eye level of an adult of average height standing adjacent thereto, the at top 82 'serves admirably as a counter over which to transact .a sale and purchase. f
The sign elements 40, shown to best advantage in Fig. 3, may be received by channel-like elements 14 suitably carried by the sign supporting surface 88. The sign elements are preferably adapted for readyremoval andv replacement to accommodate changes in the articles for sale and revision of their prices. These elements 40 may be manufactured from paper or cardboard `or from light transmitting materials such as glass or Celluloid. The paths of the light raysemanating from the light source have been depicted diagrammatically by the arrows in Fig. 3. Supplemental reflecting means 18 may redirect stray light onto the sign elementsy and may simultaneously serve as a finish' strip or bead extending from the top of the cabinet. Provision has been made for the insertion of light screens 18 which may be of light transmitting material and. colored if desired, for the production of varied lighting effects. These light transmitting elements or screens 18 may be carried in channels 80 and 82 mounted on the cabinet andhousing respectively. Such screens preferably willbe removableso 'as to permit the distribution and/or color of light to be changed if desired. l
In the modification represented in Fig. 4 of the drawings, the light source 44 is positioned behind a iight transmitting sign supporting surface 38. The source has been shown as. substantially equidistant from all portions of the sign supporting surface, tending to promote uniform illumination of the signs. In this `case the 'sign elements 40 themselves will be cut-out or of light transmitting material. In order to permit passage of light to the display compartment without substantial loss of refrigeration, a multiglazed construction 84 is interposed between the light source and display compartment and forms at leasta part of the uppergwall of the compartment. The refrigerating unit 88 'in this construction, if required, will be suitably modified to permit the necessary distribution of light. Here again, a light transmitting partition l0 may be employed between the display compartment and the refrigerated storage compartment to permit the passage of light into the latter.
In the construction shown in Fig. 5. of the drawings a multi-glazed window 84 similar to that of Fig. 4 is utilized to permit the passage of light from the enclosed source 44 to the disthe door or doors play compartment and refrigerated storage compartment. In this form a light transmitting panel 88 is placed above the light source to permit direct illumination of the sign elements 40. The panel 86 may be clear or opalescent or col- `ored as may be desired. IIhis panel may be composed of several sections of similar or dissimilar materials in the same manner as proposed forthe members 18 of Figure 3.
The construction of Fig. 6 of the drawings utilizes the housing 42 for the light source 44 from which rays are directed into the display compartment 8 8.. Here again the sign supporting surface 88 is light transmitting in nature and the sign elements 40 themselves permit the passage of light. In addition to the supplemental reecting means 18, there may also be provided avreecting surface-88 substantially parallel to the sign supporting surface or otherwise conformed to effect an optimum light distribution for approaching uniform illumination of the several sign elements.
The modification shown in Fig. '1 of the-drawings contemplates the use of an unrefrigerated display compartment |00 suitable for the reception of dummy packages to simulate the goods for sale. In this case, the display compartment is separated from the refrigerated storage compartment by an insulating partition |02 which may form a floor |04 of stepped construction to receive several rows of goods in stepped arrangement. The window |08 may be provided with a suitable hinge |08 at its lower edge to permit access to the displaylcompartment and the lamp housing 42 with its lighting assembly may be supported directly from the frame of the window so as to be movable therewith to a position such as indicated in broken lines. The'storage compartment has been depicted as containing a plurality of refrigerating elements 68, which will be connected through Jsuitable tubing, not shown, to a compressor ||0. or other refrigerating system, mounted below the storage compartment in a compartment H2. Here again, the top of the cabinet as a whole will preferably be below the eye level of an adult of avere. e height standing adjacent thereto.
