ELEOTBIQALLY-HEATED DISPLAY CABINET.

Application filed April 8, 1921. Serial No. 459,567.

To all whom it may co neevm."

Be it known that 1,. WILLIAM L. BROWN, a citizen of the United States and resident of Wichita, in the county of edgwick and State of Kansas,- have invented certain new and useful Improvements in Electrically- Heated Display Cabinets, of which the following is a specification.

My invention relates to electrically heated cabinets for holding and displaying peanuts, chestnuts, or other edibles that are intended to be kept and sold in allot condition. The object is to provide a heated cabinet that will display the goods, protect them from dust, and keep them heated to a practically uniform temperature. By employing electricity as the heating agent, I avoid the inconvenience, ba-d odor, and extra cabinet space that would be caused by the use of a fuel burner.

Referring to the accompanying drawings: Fig. 1 is a rear elevation of a c-abinetembodying my invention, portions of the door being broken out to expose the heating element and one of the lights; Fig. 2 is a diagram of the electrical connections in the cabinet; Fig. 3 is a sectional plan view taken on line IIIIII of Fig. 1, breaking a portion of the perforated heater shield; Fig. 4

is another section on line 111, viewed upwardly.

The cabinet as shown comprises the base 1, the corner posts 2, andthe top 3. The bottom plate 1 is wood, and is covered. by a sheet metal plate 4, having its edges upturned on three sides, forming flanges 4" (Fig. 3). a

The posts 2 are grooved for holding the edges of glass walls 5, which form the front and two sides of the cabinet. A door frame 6 is mounted on hinges 7 between the rear posts 2, and is fitted with a glass pane 8, and a latch 9 which holds the door in closed position.

The top 3 is secured to the posts 2 either fixedly or removably. Mounte centrally on said top is a translucent dome 10 which covers an electric lamp 12 (indicated). A second electric lamp 14 is mounted on the lower side of the top 3, for illuminating the interior of the cabinet. The top light 12 ismainly for advertising purposes.

15 denotes a glass shelf, supported by brackets 16 (Fig. 3). This shelf forms a convenient support for the commodity being sold after the same has been placed in sacks.

shown.

An electric heating element 17, Fig. 3, is placed on the bottom plate 4, though the conducting wire, if bare, will, of course, be insulated from said plate the latter being metal. a

With this heater continuously energized, the temperature of the air in the cabinet would soon become too high, except in very cold weather. In order to hold the inside temperature below an excessive degree, I purpose to employ a make-and-break thermostat, connecting same in series with the heating element and with a source of electric current. Preferably, I locate the thermostat, marked 18, at the top of the cabinet; Fig. 4 showing it as secured to the to plate 3.

he connections are diagrammed on Fig. 2,

in which the two wires 19 represent a lamp cord connected with a commercial lighting circuit. The wires supplying the thermostat 18 and the heater 17, are connected as Thus the operation of the heater will be unafiected by the condition of the lamps 12, 14 as to on or off.

When the temperature becomes too high, the thermostat will open the heater circuit and will hold the same open until the temperature has fallen to the point for which the thermostat has been adjusted; when the circuit will be re-closed and the heating process resumed.

Preferably, the top of the cabinet is to be without openings, excepting the small holes made to'pass the electric cord 19 into the cabinet.

As shown on Fig. 3, a suitable shield 20 is secured to the base over the heating element, for holding the nuts from contact with the heating element. This shield is perforated, as shown at 21, to permit circulation of air through the shield. s

The loose nuts are placed upon the bottom plate to a depth of several inches. They will in time become uniformly heated from the heating element 17. Sacks filled with the nuts are laid on the shelf 15, where they will be kept hot and ready for dispensing.

The entire metal plate 4, upon which the heating'elemcnt rests, will be raised in temperature by heat emitted by the heater 4, and said plate will thus constitute an extended heating surface whereby the nuts not directly above the element 4- will be heated.

Having now described my invention, I
