KNOCKDOWN HEAT BATH APPLIANCE Filed March 15, 1933 2 Sheets-Sheet 2 Patented Oct. 30, 1934 UNITED STATES PATENT OFFICE This invention relates to a knock-down heat bath appliance, one wherein a pliable canopy complies to and can be draped over a knock-down frame operatively supported on a stool disposed within the canopy, the canopy having a central opening and an adjoining zipper closed slot or separation, whereby the opening may be made to fit around the neck of the occupant of the stool, there being an indicator or gauge carried by the top of the canopy adjacent the separation or slot for indicating the degrees of heat within the canopy.

Said appliance also has for its purpose the provision of a heating unit including a support to be removably suspended from the bottom of the stool and including a cord having a hand switch within the canopy and a plug at the end of the cord for cooperation with any electrical outlet in the wall of a room for furnishing current to the unit, whereby heat may be generated within the canopy, the switch acting to turn on and off the current.

Another purpose of the invention is that the support for the heating unit includes a deflector in the form of an insulator between the heating unit and the bottom of the stool. This deflector and insulator consists of a plate removably suspended from the under surface of the stool seat and is provided with a marginal flange, there being heat insulating means secured to the plate within the flange said heat insulating means including two thicknesses of asbestos, one of a soft character, the other being exteriorly and of a hardened character, thereby preventingthe heat from being transmitted from the circular plate to the seat of the stool, the plate of such support being of a diameter that will direct the heat outwardly and upwardly on such an angle from the under portion of the seat of the stool, as to prevent the heat from being transmitted to the plate and then to the under surface of the seat of the stool.

It is to be understood that the particulars herein given are in no way limitative, and that while still keeping within the scope of the invention, any desired modification of details and proportions may be made in the construction of the appliance according to circumstances.

The invention comprises further features and combination of parts to be hereinafter set forth, shown in the drawings and claimed.

In the drawings Figure 1 is a View in perspective of the im-' proved knock-down heat bath appliance con-- structedin accordance with the invention showing the appliance in use, there being an occupant therein.

Figure 2 is a vertical sectional view through the canopy showing the stool in perspective, part of the canopy in perspective with the occupant therein.

Figure 3 is a sectional view through the stool showing part of the supports for the frame.

Figure 4 is a horizontal sectional view on line 4-4 of Figure 2.

Figure 5 is a view of the supporting frame for the canopy collapsed.

Figure 6 is a View with a portion of the seat 2 in section and the metal shield 44a in section, the marginal flange 35 in edge elevation, and other attendant parts associated therewith in elevation, more clearly disclosing the structure.

Referring to the drawings 1 identifies a stool, which comprises a seat 2 which may have any suitable finish and provided with a downward marginal flange 3. Riveted or otherwise secured to the flange at 4 at the four corners of the stool are legs 5, which are made of angle iron, and riveted to the legs at '7 near their lower ends are angle iron braces 8. The legs may be provided with any suitable finish while the braces may be finished in any conventional manner. Adjacent the two front corners of the flange of the seat' extensions 10 of sockets 11 are fastened by any suitable means preferably electrically welded, certain of the rivets for the front legs passing through the extension of the sockets. To the flange of the seat at the rear thereof an extension 12 of a third socket 13 is electrically welded. A plurality of supports 14 for a canopy supporting ring 15 is provided. Each of these supports 14 comprises a long section 16 and a short section 17 pivotally united at 18. The long section consists of relatively heavy twisted wire as shown, the loop at the lower end receiving the pivot 19. The upper portions of the relatively heavy twisted wire diverge upwardly into arms 20 which terminate in eyes 21 to receive the canopy supporting ring, there being flxed collars 22 on the ring adjacent the remote sides of the eyes of the arms to prevent any displacement thereof. The short sections of the supports have down turned ends which engage into the sockets carried by the flange of the stool seat.

A canopy 23 includinga circular part 24 and a skirt 25 is provided. The circular part corresponds in diameter tothe supporting ring and engages therewith, while the skirt drapes down over the frame. The approximate center of the circular part has an opening 26 which fits around the neck of the occupant, while the circular part has a separation 27 extending radially from the central opening, and the edges of the separation 27 may be closed by a suitable zipper fastener 28. Adjacent this separation an indicator or gauge 29 is provided, from which the occupant can easily observe the temperature of the interior of the canopy.

A tongue 30 is electrically welded to the under surface of the seat of the stool, the free part of the tongue being spaced from the seat. A bracket 31 is provided having flanges 32 constituting guides to engage with the tongue for suspending the bracket. Secured to lateral ends of the arms of the bracket by screws is a deflector 33. This deflector comprises a metal plate 34 with a marginal flange 35 and secured to the plate 34 are suitable discs of

heat insulators

36,and 37, the insulator 36 being of soft asbestos and the insulator 37 being of hardened asbestos with a lower exterior finish. A support 38 for a heating element'39 is'provided. Thissupport comprises a metal ring 40 and a porcelain dependent 41 secured'together at'42. The securing screws for the lateral ends of the arms of the bracket pass into the ring. The porcelain dependent has the usual threaded socket for the heating element, there being the usual protecting cage 44 clamped about the restricted end of the porcelain dependent. In Figure 6 instead of the cage 44 a very slightly tapered metal shield 44a is clamped about the restricted end of the porcelain dependent and is provided with perforations 44b which allows'the excessive heat to escape and be deflected by the deflector 33. A suitable cord 45 including interior conductors (not shown) pass hand switch 47 having the conventional type of

push buttons

48 and 49, whereby the current may be turned on and off. In using the apparatus the frame may be con- 9 nected to the sockets of the stool, then the canopy can be draped over the frame, it having been first placed over the user while sitting on the stool, the hand switch being within the canopy, so that after closing the separation in the circular part of the canopy the switch may be turned on for supplying current to the heating element. The occupant remains within the appliancefor a time sufficient to create a thorough sweat, it being possible for the occupant to observe the gauge or indicator in order to observe the temperature on the interior.
