Nov. 8, 1949 D. D. ROBERTS BED WARMER Filed June 22, 1948 Dar/jug D. Roberts INVENTOR BY @Mm Patented Nov. 8, 1949 UNITED STATES PATENT OFFICE BED WARMER Darling D. Roberts, Cross City, Fla.

Application June 22, 1948, Serial No. 34,501

1 Claim.

This invention relates to an improved device for use in conducting heat, particularly in a bed.

An object of this invention is to supply heat generated by conventional bulb within a bed, for use by individuals desiring or requiring additional heat within a bed.

An object of this invention is to supply a housing having at least one and preferably two sockets therein which accommodate conventional lamps in order that the heat produced by the lamps may be conducted between covers in a bed.

Another object of this invention is to provide an extremely simplified device of the character to be described which serves its intended function effectively.

Other objects and features will become apparent to those skilled in the art, following description of the preferred form of the invention,

illustrated in the accompanying drawings, wherein:

Figure 1 is a perspective view of the preferred form of the invention;

Figure 2 is a longitudinal sectional view of the invention shown in Figure 1, and;

Figure 3 is a sectional view taken transversely of Figure 1 and substantially on the line 3-3 thereof and in the direction of the arrows.

This invention relates to a novel means of supplying heat within a bed. Of course, the invention may be used in other connections other than in a bed, as it may be used wherever it is found desirable to supply heat.

As is well known it is an ancient custom to warm bricks, stones or the like and place them in a bed to heat a portion thereof, particularly in cold weather. Such custom has long passed in this country however, the custom has been superseded by the use of water bottles, heating pads and heated blankets. It is therefore within the purview of the present invention to provide a device of the class which may be included in that of the heating pad, hot water bottle, etc.

The specific structure of the invention includes a cylindrical housing In of transparent material which will permit radiant heat to extend therethrough and which will also conduct heat. This cylindrical housing has closures I2 and [4 respectively attached thereto at each end and has an annular reduced portion l6 and I8 on each respectively which is adapted to frictionally seat in the bore of the cylindrical member l0. By this construction the outer surface of the cylindrical member is flush with the closures l2 and M.

In each closure l2 and I4 respectively there is an identical structure provided. This identical structure includes an opening centrally thereof which accommodates a socket generally indicated at 22. This socket has a groove 26 adjacent one end thereof which is adapted to frictionally seat in the opening 20. Of course, the socket may be of a resilient material in order to firmly clamp in place.

A conventional lamp 28 is provided in the socket 22 and this lamp of course emits heat. The heat both radiant and conductive warms the adjacent articles which may be positioned at a location of propinquity to the invention.

A pair of conductors generally indicated at 30 extend from a suitable nipple 32 in the said socket 22 to a second identical socket generally indicated at 34 wherein a second lamp 36 is provided.

Of course, a suitable conductor of electric current 38 may extend from the socket 22 and may have the usual plug 39 at the end thereof in order to associate the same with a source of current.

Due to the extreme simplicity of the invention a further description is deemed unnecessary. It is understood of course that variations may be made without departing from the spirit thereof.

Having described the invention, what is claimed as new is:

A heater comprising a transparent sleeve having open ends, closures secured to the open ends of said sleeve, each closure having a reduced end portion, and the open ends of said sleeve disposed in said closure reduced end portions, each of said closures having an aperture, a first and a second socket of resilient material, each of said sockets having a groove therein, said grooves cooperating with the edges of said closures around said apertures forming means retaining said sockets in said apertures and said sleeve, heating elements disposed in said sockets, an electrical conductor disposed in said sleeve and secured to said sockets connecting said sockets for electrical communication, and an electrical outlet lead from one of said sockets.
