BED.

Application filed March 7, 1925. Serial No. 18,926.

This invention relates to the construction of beds whereby the temperature of the air surrounding the sleepers' body vmay be controlled, or the other characteristics of air changed as desired, as, for example, by the addition of moisture or various vapors or gases.

We attain our object by means of the constructions hereinafter described and illustrated in the accompanying drawmgs m which Fig. 1 is aside elevation, partly broken away, showing a bed constructed in accordance with this invention; and

Fig. 2 a vertical section of the same.

In the drawings like numerals of reference indicate corresponding parts in the'difierent figures.

1 is a bedstead, which may be of any ordinary form. Over the bed is supported a canopy which comprises a dome 2, preferably of frusto-pyramidal form, and a 3. The dome is formed of an suitable material impervious to air, pre erably bri ht sheet aluminum, while theskirt is forme of a suitable textile fabric through which air may pass more or less freely. This canopy may be supported in any convenient manner- In order that the bed may be independent so, of an exterior support and thusbe readily porta le, we prefer to extend upwardly two of the legs of thereto a U- haped frame 4 suitably connected with the dome 2. Within the dome is supported a heating element 5, preferably electric. The dome is also provided with certain partitions to cause the air heated by the heating element 5 to ass downwardly towards theupper surface of the bed before passing upwardly and out of one or more air vents-6 in the top of the dome. These vents may be supplied with chimneys 7 in which are located dampers 8 by means of which the rate of exit of heated air, may be controlled- The partitions referred to are preferably formed by a frusto-pyramidal reflector 9 substantially parallellmg the sides and top of the dome2. The heating element is preferably located adjacent the top of this reflector, and-a shield 10 may be located below the heating element to cut off the direct downward radiation of the heating element. With this arrangement air passes through the bedstead and-to connect the material of the skirt and a'dually rises 66' to take the place of air heated y the heatin element 5 which follows the course indicated by arrows. With this arrangement we find that theair above the sleeper is constantly changed,-while its temperature is modified so by the heating device shown. With this arrangement, by suitabl controlling the heatingelement, an equab e temperature may be obtained within the canopy so that bed clothes may be dispensed with, if desired, 66 and the sleeper obtain the advantage of a constant flow of heated air over his body. It is also evident that the characteristics of this air as to temperature may be varied as desired, and that remedial vapors or gases 7 may be generated through the medium of the heating apparatus.

A wire mesh screen 11 is preferabl located at the bottom of the dome to brea up the air currents as much as possible, also 76 to intercept anything liable to injure the patient in caseof trouble with the heatlng means.

While, under some circumstances, bed clothes may be dispensed with in other 80 cases, they would be indispensable, and I therefore provide means whereby the margins of the clothes may be suitably tucked in without interfering with the skirt .of the canopy. For this purpose I provide a low 86 wall 12, which preferably extends alon each side and across the bottom of the bed from points adjacent but not close up to the head of the bed. This wall is preferably formed of heavily quilted material so as to possess 90 a considerable measure of vertical stiffness while it is readily bent into the U-form shown and its lower edge secured to the mattress at the margins of the un ersurfaces thereof. The skirt 3 hangs closely over this wall, while the bed clothes may be tucked in between the wall and the edge of the mattress.

Thisarrangement is not only a plicable for use in the manner hereinbefore escribed,

but provides convenient means for giving light treatments to patients, light emitting means of desired characteristics being substituted for the heating element 5.

What we claim is A canopy adapted to besupported over a bed comprising a dome substantially impervious to air having an air vent at its top;

a porous flexible skirt connected therewith;

means for admitting air beneath the canopy;

heating means within the dome provided with a reflector located within the dome and spaced therefrom and adapted to throw the heat downward towards the bed. the heated air then flowing upward through the space between the reflector and the dome to the air vent; and a shield below said heating means & adapted'to intercept the direct down- 10 ward rays of the heating element.
