HEATING ATTACHMENT FOR LAMPS Filed May 29, 1944 Patented Aug. 3l, 1948 AUNI-Trl) STATES eATENT OFFICE v HEATING ATTACHMENT FOR LAMPS Llewellyn M. Roberts,` Northfield, Vancouver l Island,l British Columbia, Canada Application May 29, 1944, Serial No. 537,825

3 Claims. (Cl. 126-258) This invention relates to heating attachments for illuminating lamps, and has for the primary object the provision of a device of this character which may be easily and quickly adapted to an oilburning illuminating lamp and which provides an eflicient support for a container on the lamp for heating small amounts of water to be used for domestic purposesby the heat derived from the lamp and which Will in no way affect the proper functioning of the lamp or the carrying of the lampfrom place to place.

With these and other objects in View as Will become more apparent as the description proceeds, the invention consists in certain novel features of` construction, combination and arrangement of parts as will be hereinafter more fully described and claimed.

For a complete understanding of my invention, reference is to be had to the following description and accompanying drawing, in which Figure `1 is a side elevation illustrating a heating attachment for lamps constructed in accordance with my invention.

Figure 2 is a top plan view illustrating the attachment.

Figure B is a sectional view taken on the line 3-3 of Figure 1.

Figure 4 is a fragmentary vertical sectional View showing the means for directing the hot gas and air of the lamp to the container supported by the attachment.

Referring in detail to the drawing, the numeral 5 indicates an oil burning illuminating lamp of a conventional construction including the usual base 6 in which the supply of fuel oil is located, a burner 'l and a transparent chimney 8. A lamp of this kind Will throw off considerable heat escaping at the upper end of the chimney 8 and it is the purpose of the present invention to utilize this heat for the heating of small quantities of water to be employed for domestic purposes.

The present invention is in the form of an attachment including a support 9 which may be readily adapted to the chimney 3 and removably held thereon against accidental displacement by yieldable tie elements I0 each including a hook shaped member II and a coil spring I2 provided with a hook I3 to engage under the burner 1. The hook shaped member II engages with the support. The support includes a plurality of superimposed annular bands I4 adapted to surround and wedge upon the chimney 8, except the uppermost band which is slightly spaced from the upper end of the chimney, as clearly shown in Figure 4. The bands are connected by vertically arranged strips or members I5. so that the support is more or less of a rigid construction. The lowermost band I4 has olsets I6 to be engaged by the hooks of the hook-shaped member I Iof the tie elements Ill to prevent displacement from the support.

An annular rest I'I of a diameter larger than the diameter of the uppermost band I4V is connected thereto by spaced members Iextending radially from the inner periphery of said rest and terminating adjacent the central point of thelatter, as shown in Figure 2.

Any type of container may be-arranged on the rest, preferably of .a tea-kettle type, as shown` at 2B', the lower portion of which is reducedin diameter and provided with"v annular corrugations so that the contents of the kettle will more readily become heated by the heat from the lamp chimney passing over the corrugations.

To concentrate theheat about thel lower portion of the kettle, and still not interfere with the draft for the burner provided by the4 chimney a. hot4 gas andair` directing band 2| is provided which is concentrically mounted on the annular rest Il andattached thereto by means of av plurality of spaced members 22 projecting radially from the inner periphery of said band.- The diameter of the band 2| is slightly greater than the external diameter of the kettle 20 so that the hot gases from the chimney may rise upwardly and travel against the lower portion of the kettle especially the corrugated portion thereof.

Thus it will be seen that an attachment has been provided readily adaptable to an oil burning lamp of a conventional construction so that the heat from the lamp may be utilized for heating the contents of a container arranged upon the .attachment without interfering with the natural draft of the chimney for the proper com- -bustion of the fuel at the burner. Further, it will be seen that the attachment is held against accidental displacement, however, it may be readily detached from the lamp whenever desired. It will also be noted that when the attachment is applied to the chimney it does not materially destroy to any great extent the illuminating value derived from the lamp.

While I have shown and described the preferred embodiment of my invention, it will be understood that minor changes in construction, combination and arrangement of parts may be made Without departing from the spirit and scope of the invention as claimed.

Having thus described my invention, what I claim is:

1. In an attachment for a fuel-burning illuminating lap including a burner, a support comprising a plurality of spaced vertically arranged members, a plurality of bands arranged in spaced superimposed coaxial relation with respect to each other and connected to said members, an annular rest for the accommodation of a receptacle thereon mounted upon the uppermost of said bands and connected thereto, said rest having a plurality of spaced members extending radially from the inner periphery thereof `and terminating adjacent its central point, a heat-retaining band provided with a plurality of spaced members projecting radially from the inner periphery thereof concentrically mounted on said rest, the ends of the radially extending members on said heat-retaining band being attached to the outer periphery of said rest, and a plurality of spaced yieldable tie elements having one of their ends attached to the lowermost of said bands and the other of said ends to said burner.

2. In an attachment for a fuel-burning illuminating lamp including a burner, a support comprising a plurality of spaced vertically arranged members, a plurality of horizontally disposed bands arranged in spaced superimposed coaxial relation with respect to each other and connected to said members, an annular rest for the accommodation of a receptacle thereon mounted upon the uppermost of said bands and connected thereto, said rest having a plurality of spaced members extending radially from the inner periphery thereof and terminating adjacent its central point, a heat-retaining band provided with a plurality of spaced members projecting radially from the inner periphery thereof concentrically mounted on said rest, the ends of the radially extending members on said heat-retaining band being attached to the outer periphery of said rest, said heat-retaining band being of a, diameter greater than the external diameter of said rest, and a plurality of. spaced yieldable tie elements having one of their ends attached to the lowermost of said bands and the other of said ends to said burner.

3. In an attachment for a fuel-burning illuminating lamp including a burner, a support comprising a plurality of spaced vertically arranged members, a, plurality of bands arranged in spaced superimposed coaxial relation with respect to each other and connected to said members, an annular rest for the accommodation of a receptacle thereon mounted upon the uppermost of said bands and connected thereto, said rest having a plurality of spaced members extending radially from the inner periphery thereof and terminating adjacent its central point, a

heat-retaining band provided with a plurality of spaced members projecting radially from the inner periphery thereof concentrlcally mounted on said rest,the ends of. the radially extending members on said heat-retaining band being attached to the outer periphery of said rest, and a plurality of spaced yieldable tie elements having oneof their ends attached to the lowermost of said bands and theother of said ends to said burner, each of said tie elements embodying a hook-shaped member and a coil spring provided with a hook on an end thereof connected to said hook-shaped member, the hooked end of the latter engaging the lowermost of said bands and thehook of said spring engaging the base of said burner.
