HEATING APPLIANCE 2 SHEETS-SHEET 2 Filed Oct. 17, 1951 Patented Mar. 10, 1953 HEATING APPLIANCE Alfredo Alvarez, J unin, Argentina Application October 17, 1951, Serial No. 251,719 In Argentina November 29, 1950 3 Claims.

This invention relates to improvements in heating appliances, the main object being that of" providing said heaters with suitable means whereby they may be used as clothes-drying apparatus when required, without affecting the appearance of the heating appliance or the parts thereof.

A serious problem is found in most homes during the rainy season, since it is not possible to hang the clothes in open spaces and it is therefore necessary to dry the clothes by adopting very inconvenient, non-sanitary and sometimes dangerous methods. Under such circumstances, the clothes are frequently hung in bathrooms, kitchens or other sheltered spaces. The drying of the clothes in such cases is obviously slow and often insanitary due to occasional dropping of the clothes onto a floor which may not always be clean, and dangerous when the clothes are put to dry over a kitchen stove, which is sometimes done in order to obtain a quicker drying of clothes which are needed urgently, since they may be easily burned due to the presence of fire spots generally existing in such stoves.

Several clothes-drying equipments are known,

based on different principles and, while they are generally satisfactory, dueto the highcost thereof they are not within. the reach. of relatively modest homes.

A study of the. problem disclosed that gen.- erally the garments which are most urgently needed are the smaller garments or babies clothes which could be dried on a device forming part of. a heating appliance, thereby giving the latter a, double use without affecting the appearance thereof when the deviceis used as a stove, and therefore it was possible to devise the improvements ofthis invention.

A heating appliance has beendevised, circular in, horizontal section, formed with a central conduit having slidably mounted therein a cylindrical, member, said, member carrying pivoted thereto a plurality ofarms which in their inoperative position are housed vertically in said conduit; an actuating means fixed to said cylindrical member and a plurality of cords depending from the free ends, of the arms, the latter being capable of assuming different planes in view of the fact that, they are. pivoted to said cylindrical member slidable in. the. above-mentioned conduit'. Completing the assembly, the appliance has means for fixing the cylindrical member'in its operative position and means for graduating the different positions capable of being assumed by said arms, whereby the cords on which the garments are to be hung may be stretched in the same manner as an ordinary clothesline. The assembly of arms and cords will remain located over the heating appliance, whereby the clothes hung on the lines will receive a current of air heated by the sources of heat. When it is desired to use the device as an ordinary heater, it will be suificient to collapse the arms so that they are postioned vertically, whereupon the assembly is enclosed in the conduit, where it will remain concealed.

In order that the invention may be more clearly understood and readily carried out, a preferred embodiment thereof has been illustrated. by way of example in the accompanying drawings, in which:

Fig. 1 isan elevational view of the heating appliance, with the clothes-hanging assembly concealed in the corresponding housing.

Fig. 2 isa cross-sectional view taken along the lines A-B in Fig. 1 and showing the, position of the collapsed arms in the conduit.

Fig; 3 is a view illustrating the: arms drawn out of the housing, together withthe actuating means, and showing theadjusting screw-holding the assembly in such position, the arms being shown in collapsed vertical position.

Fig. 4 shows the same devices of. Fig. 3, but with the arms extended, the dotted linesindicating the cords on which the clothes are to be hung and the different positions: capable of being assumed by said arms.

The same reference characters are used to indicate like or corresponding parts or elements throughout the drawings.

With reference to the drawings, the equipment comprises a heating element a. constituted in this instance by electrical heaters l These-heaters l are located at the focal points of respec tive parabolic reflectors 2, the surfaces 3 of'which are highly polished for a better reflection of the heat rays emittedby the resistors I.

The resistors l are vertically positioned and held by respective supports 4 provided on the base 5 and head 6 also parabolic in shape and 1 3 having reflecting properties. The resistors are supplied with electricity by connecting same to the main line through the terminals l, the circuit thereof comprising a regulating and cut-off switch 8.

The parabolic reflectors 2 are joined together by their sides 9 and through the respective bases 5 and the parts constituting the heads 6.

Due to the shape of the reflectors 2, when they are joined together by their sides they will form a cavity in which is used for including therein a cylindrical tube ll (Fi 2) communieating with the exterior through an orifice l2 formed in a cover piece I 3. Said tube H extends beyond said orifice l2 and near the end thereof it is provided with supports [4 on which there is pivoted a handle [5. This assembly is supported by a base [6. The resistors l are protected by means of a plurality of rings I! which are firmly attached to the sides of the reflectors 2.

An assembly b is inserted in the bore of tube ll, said assembly being constituted by a cylindrical member l8 coinciding with the cross-sectional area of said tube. A rod I9, preferably cylindrical, emerges from the center thereof, said rod terminating in a cap provided with a finger-ring 2|. A plurality of rods 22 are pivoted to said cylindrical member l8. Slidably mounted and surrounding the rod Hi there is provided a further cylindrical member 23, substantially smaller in diameter than the cylinder l8 and on which there are pivoted a like number of rods 24, the ends 25 of which are pivoted to the respective rods 22, at a point between the ends thereof.

On the portion of the tube ll projecting through the orifice 12 in cover 13, there is provided a threaded perforation adapted to receive a screw 26 capable of firmly engaging the cylinder I8 and holding the tube IS in its operative position. Also, the cylindrical member 23 is traversed by a screw '21 constituting the means for fixing the arm assembly in given positions.

Depending from the arms or rods 22 there is provided a plurality of cords 28 (shown in dotted lines in Fig. 4) on which the garments to be dried may be hung.

When it is desired to use the appliance as a clothes-drying device, the handle l5 should be moved from the position shown in Fig. 1 to the position illustrated in Fig. 3. The assembly b 'is pulled upwardly by means of ring 2! until the cylindrical member i8 is positioned at the mouth of the tube l I, where it is held by means of the adjusting screw 26, whereupon the arms 22 are extended to the desired position and fixed by means of the screw 2'! on the slidable member 23. The device will then be ready for use and the clothes to be dried may be fastened on the cords 28. When it is desired to use the equipment as a stove or heater, the operations are reversed, i. e., the screw 21 is loosened, the arms 23 are 001- lapsed until they remain vertical, the adjusting member 26 is unscrewed and the whole assembly b is housed in the bore of tube I I, where it will remain concealed.

It is evident that in carrying out the invention, many changes, modifications and/or alterations will occur to those skilled in the art, without departing from the scope of the invention as clearly set forth in the following claims.
