It will also be noted that the entire interior of the heating unit 15 is encased with an insulating material which prevents the escape of heat to the atmosphere and delivers practically all of the heat generated to the fluid in the basin 10.

It will thus be seen that there has been provided a practical and economical arm bath which is adapted. for various uses to which it is desired to keep fluid at a constant temperature throughout a period of time.

It is realized that the invention is susceptible to various changes and modifications coming well within the scope of one skilled in the art, and it is not, therefore, desired to limit the invention to the precise embodiment herein shown and described, but only by the scope of the appended claims.

What is claimed as new and desired to secure by Letters Patent is:

1. In a device of the character described, a basin,

a heating unit beneath said basin comprising, a rectangular receptacle having an aperture in its top wall shaped to conform to said basin to receive the bottom portion thereof, a lining for the interior of said receptacle comprised of heat insulating material, brackets on the interior of said casing forming a support for said basin with a part of the basin projecting into the interior of said casing, a heating element within said casing and means to vary the amount of heat emitted by said heating unit.

2. In an arm bath, the combination of an elongated basin, a cover for the basin having provision for the insertion of an arm into the basin, a heating and supporting unit for the basin comprising a rectangular box closed on all sides and provided with an opening in its top wall to receive the basin, said opening being shaped to conform to the basin, and to have a close fit therewith, means projecting from the side walls of the box to support the basin, electric heating means within the box, and a switch on the exterior of the box to control the heating means.
