4 Claims.

7 This invention relates to a combined electric lamp and utility heater, wherein the heater may be used for the preparation of hot refreshments while entertaining guests in the living room without interruption, or for preparing meals by a bedridden person, while the lamp is used to illuminate the living room or bedroom.

It is an object of the invention to provide a lamp stand or pedestal with an electric heating element which will not detract from the artistic appearance of the lamp pedestal.

It is another object of the invention to provide a heater combined with a lamp which will not materially increase the cost of manufacture of the lamp.

It is a further object of the invention to provide a combined lamp and heater wherein the heater may be converted into an article support without interfering with the utility of the heater.

It is a still further object of the invention to provide the heater of a combination lamp and heater with a conveniently located switch whereby a person may connect or disconnect the heater with an electric circuit without arising from a. chair located adjacent the combination lamp and heater.

A still further object of the invention is to mount a heater on a lamp pedestal without overbalancing the lamp pedestal.

In the drawing accompanying and forming a part of this application,

Figure 1 is an elevational view of a bridge lamp having combined therewith a utility heater.

Figure 2 is a fragmentary View, on an enlarged scale, and partly in section to show the mounting of the utility heater on the pedestal of the lamp, electrical connection of an electric heating element to a source of supply, and means to convert the heater into an article support.

Figure 3 is a plan view of the electric heating element of the heater; and

Figure 4 is a perspective view of a cover constituting the means for converting the heater into an article support, the cover being partly broken away to show the structure of the same.

In illustrating the embodiment of the invention in the accompanying drawing, there is shown a floor lamp of the type known commer cially as a bridge lamp comprising a pedestal 5 of tubular material having a supporting base consisting of a plurality of foot members 6 of scroll formation connected to one end of the pedestal.

An electric lamp socket 1 arranged with a pull chain actuated switch, as indicated at B, and having a lamp shade 9, is supported on the end portion of the pedestal opposite the base 6 by a hollow arm bracket if) having at one end a pair of parallelly extending members rotatably 5 mounted on the pedestal, as at H, and the opposite end adapted to support the socket I by a tubular member fixed at the opposite ends in the socket and bracket, as shown at E2 in Figure l. The lamp socket is electrically connected to a 10 source of electricity by an electric conductor [3 having a blade contact terminal plug M at one end and engaged and extended into the bores of the pedestal 5, the bracket H3 and the supporting member 2 with the opposite end of the conductor connected to the terminals of the socket. To provide the pedestal with an electric heater without detracting from the appearance of the lamp pedestal or interfering with the distribution of the weight or" the lamp pedestal whereby it will not become top heavy, a portion of the pedestal intermediate the lamp bracket l0 and the base 6 and usually near the base, is offset or bent laterally of the longitudinal axis of the pedestal to U form, as at I5 in Figure l.

The heater comprises a dish shaped casing member it, in the present instance of semispherical shape, but which may be of suitable angular form corresponding to the design of the lamp and pedestal. The lower or closed portion of the member i6 is arranged with an opening I! centrally thereof and connected to a tubular portion is having at one end an exterior shoulder i9 to engage the outer surface of the lower portion of the member l5 and facilitate the connection between the member I6 and the tubular portion 58, as by soldering or Welding. The bore of the tubular portion i8 and opening ll are in alinement with each other. The opposite end of the tubular portion H is cut at an angle corresponding to the angle of the juncture between the portion of the pedestal 5 adjacent the base 6 and U portion 85, as clearly shown at 25] in Figure 2, whereby the tubular portion 5 8 is mounted on the pedestal and permanently attached thereto by soldering or welding. The wall of the pedestal 5 engaged by the tubular portion 58 is arranged with an opening 2% in alinement with the bores of tubular member l8 and the pedestal portion 5 adjacent the base 6, to permit the passage of an electric conductor 22 connected to the conductor [3 and having terminal portions extended into the casing member l6. One wire of the conductor 22 is connected to a terminal of switch mechanism indicated in a general way at 23 and mounted in the member [6 relative to an opening in the wall thereof for the passage of an actuating lever of the switch mechanism, as shown at 24 in Figure 2. The other wire of the conductor 22 is connected to a contact of a pair of contacts in the form of pins 25 mounted on and insulated from a leg portion of an angle bracket 26 having the other leg portion thereof mounted on the wall of the member 16. The other contact pin 25 is connected by a wire 21 to the terminal of the switch mechanism 23 opposite to the terminal thereof connected to conductor 22. The bracket 26 is mounted in the member it to position the contact pins 25 in a vertical plane adjacent to a horizontal shoulder extending around the open end and below the edge of the member it, as at 28.

The heating element of the heater comprises a disk or plate 29 of heat refractory and electric insulating material and of a diameter to engage the shoulder 28 of the member IE, The upper face of the plate 29 is arranged with a continuous sinuous groove having the ends tl'Tereof terminating adjacent and in parallel relation to each other, as shown at 30 in Figure 3. An electric resistance coil Si is engaged in the groove 30 with the opposite ends of the coil connected to tubular or socket contact members 32 fixed in the plateat the ends of the groove 30 and having the socket portions projecting from the face of the plate opposite the grooved face to engage and make contact with the contact pins 25 mounted in the member I6 when the plate 29 is engaged on the shoulder 28, as shown in Figure 2. By the arrangement of the releasably electrical connection between the heater coil 3| and the contacts 25, it is possible to remove the heater plate 29 from the supporting member 16 to permit the repair of the switch mechanism 23 or the contacts 25. The thickness of the plate 29 and the length of the portion of the member l6 extending above the shoulder 28 are substantially the same so that the grooved face of the plate 29 will be flush with the edge of the member H5. The coil 3| is of less size than the depth of the groove 30 so that the coil will lie below the grooved face of the plate 29.

The heater [6, 29 may be readily converted into an article support by a cover plate 33 having the peripheral portion arranged with a depending flange having a curled or beaded edge, as shown at 34 in Figure 4. The diameter of the plate 33 is such as to have the flange slidingly engage the outer surface of the portion of the member l6 above the shoulder 28, as clearly shown in Figure 2. When it is desirable to use the heater as an article support, the heating element 29, 3! is removed from the member l6 before placing the cover plate 33 on the member [6 to avoid the placing of the heating element in circuit with the source of electricity by an accidental actuation of the switch 23.

The heater i6, 29 will be mounted centrally V of the vertical axis of the pedestal and there fore, there will be no possibility of tilting over the pedestal by placing a cooking utensil on the heater plate 29.

The lamps of the type illustrated in the drawing are usually positioned adjacent a chairand the location of the switch 23 in the member I6 will permit the person seated in the chair to readily control the connecting and disconnecting of the heating element 3| with a source of electricity.

The switch 23 may be arranged as a four way switch to control the circuit of both the lamp socket I and the heating element 31, so that the lamp socket may be placed in circuit when the heating element is out of circuit, the heating element may be placed in circuit when the lamp socket is out of circuit, and both the lamp socket and heating element may be simultaneously placed in or out of circuit.

It should be understood that the heating element shown and described hereinbefore may be used with any lamp socket supporting pedestal having the general characteristics of the lamp and pedestal shown in the accompanying drawing and that the invention is not restricted to the particular lamp pedestal illustrated in said drawing.

Having thus described my invention, I claim:

1. In a combined illuminating and cooking means, a pedestal of tubular form in cross section having straight end portions and an offset portion intermediate the end portions, one end portion being arranged with a supporting base at the free end, a tubular extension projecting from the end portion arranged with the supporting base, an electric lamp socket supported on the end portion of the pedestal opposite the end portion arranged with the base and having electric conductors extending through the straight and ofiset portions of the pedestal, a dish shaped member mounted on the tubular extension to extend into the space formed by the offset portion, and an electric heating element supported by the dish shaped member and having electric conductors extending through the tubular extension and connected to the conductors of the lamp socket.

2. In a combined illuminating and cooking means as claimed in claim 1, a manually operative electric switch mounted in the dish shaped member and connected to the electric conductors of the heating element.
