DRYING APPARATUS.

Application filed December 4, 1919, Serial No. 342,428. Renewed May 13, 1926.

This invention relates to apparatus for drying wet laundry of any kind or description in a very short time, without danger of burning such laundry.

My invention consists essentially of a structure composed of one or more inclined surface plates enclosed on all sides, with the exception of an opening for the admission of hot air arising from a flame or a heater beneath the drying apparatus. The apparatus is self-containedwithout any connection for a flame Within the apparatus itself, and the temperature within is substantially uniform all over, by making use of heated air or gas to come in contact with the drying surface plates. In the accompanying dra wing forming part of this specification, Figure 1 shows a cross sectional View; Figure 2, a sectional side elevation through AA of Figure 1; Figure 3, a cross section through 13-13 of a modified structure embodying my invention, and Figure 4: a side View of the same, partly in cross section through line DD. Figs. 5 and 6 show modifications of portions of the device. In the drawings, like letters represent like parts in all the figures.

(I, a, denote a plurality of inclined surface plates made of any suitable material, preferably, galvanized or enam'elled sheet iron, or sheet iron, dipped in some anti-rust solution.

5 is the bottom plate which closes the drier at the bottom except for an opening 0 to admit the heat into the interior.

cl, (Z, are end plates, which cover the ends of the inclined surfaces.

7) and (Z may be made of any suitable material, preferably a non-conductor, to prevent the dissipation of heat through the ends and through the bottom of the drier. If desired, Z), d, may be made of metal, covered on the interior, or exterior, with a nonconducting material or a non-conducting paint y, as shown in Fig. 2. a, a, are prefer..-

ably made of material termed as a good conductor, so that heat from the inside should readily be transmitted to the outside, which, when in use, is covered with the wet laundry. It can thus be understood that in this drier, heated air or. gas is relied on to keep the entire surface which is coming in contact with the wet laundry at a uniformtemperature, and the entire space within the drier is enclosed, except where necessary to admit the heating medium; this heatlng medium may be admitted from the bottom as shown, or through one or more openings in any portion of the apparatus. As the heat is chiefly, if not entirely, dissipated through these inclined surface plates, which come in contact with the laundry, the heat units within the apparatus are used for useful work with a minimum of loss' This could not be accomplished if a flame were directed against the surface plates (1, a, for it would cause overheating of the metal in some portions of the apparatus; and if the device had an opening at the top, or at the sides, or were entirely open at the bottom, a great deal of the heat would escape without doing any useful work.

To prevent the flame, or too great a heat, from touching the inside of the surface plates at, a, shields f, f, of any suitable material are interposed, wherever it is liable to cause overheating. When in use the drier is preferably placed directly over a burner of a gas range or any other heating means, the opening 0 resting over the flame. The arrows 0: representing the flame or the heat entering the drier.

7' represents a portion of the gas range with burners is, shown underneath the opening 0 of the drier.

Therefore, the flame will take the necessary oXy en for consuming the gas from Without t e apparatus, whereas the heating medium will rise directly into the drier and will, substantially, uniformly heat the in terior of the entire apparatus. The shield plates 7, 7", may be composed of any suitable material and'may consist of single plates, or of a plurality of plates with air spaces between the plates, as shown, or of metal, and a non-conductor a, like asbestos, placed between it and the surfaces they are to shield. If desired instead of being made as shown, they may simply consist of asbestos sheets fastened directly to the surfaces wherever the flame from the gas range may strike them or come too close to them, to prevent over-heating or hot spots as shown ill-Fig. 5. s, s, are supports by whiohthe shields are held in place.

The drier may be made in sections, detachable, or collapsible as shown in Figures 3 and l, to fold up when not in use. In Figures '3 and 4, g, 9, show the central members of hinges where the inclined surfaces fold together, while it shows ahinge or any other suitable attachment between the end plates 05 and the bottom plate 6. Instead of hinges, any suitableconstruction may be employed to detachably connect the various plates with each other. The bottom plate can also be hinged with a if desired, as shown in F 1g. 6, or in any convenient manner, or it may be curved around the edges as show-n at i, so as to be in sliding connection with some of the surface plates 0:, a. It is understood, of cou rse, that the end plates (Z, the surface plates a, and the bottom plate I), may be attached with each other either rigidly or in any known collapsible or detachable manner as is evident to anyone skilled in the art.

In the arrangement shown in Figures 3 and r, the four inclined surface plates are in hinged connection with each other, while the end plates and the bottom are hinged together. If desired to disassemble the drier when not in use, it is only required to take off nuts 0 and unhook catches p when the four inclined surface plates can be folded together, and the bottom plate and the end plates can be folded up. lVhen assembling, the bottom plate and the end plates may be placed flat on a table; then the surface plates at, a, are placed in position with the two outermost plates inside 2' of the bottom plate, then the two end plates are folded upward and are attached to a, a, by means of catches p or nuts 0, or any other suitable means.

If desired, the outside of the surface plates (1, a, may be covered with a wire netting or any other material to keep the wet laundry a certain distance from the said plates. This arrangement would however, not be as efficient as where the laundry comes in direct contact with the heated surface plates. At m is shown a projection running along the lower ends of the surface plates to prevent the laundry from reaching down to the top of the gas range, and at the same time it may serve to lead away the dripping water which may come down from the wet laundry. Since there is no burner with the apparatus, 110 outlet is required for the burned gases, and, in this manner the heat within the device is used to the best advantage. A small opening 1" may be provided at or near the bottom to observe the flame for adjustment, or to note if the shields are becoming overheated, in which case the gas flame may be turned lower, since only a very small flame is required. If desired this opening may be covered by meansof a piece of mica or'other suitable transparent ma.- terial. Even if open comparatively little, heat. would escape because itislocated near thebottom. p p

If found convenient, any suitable means may be provided for keepin the Literary may be found especially useful for handkerchiefs, towels, and the like. When not in use a hook or catch provided on the drier can be employed to hang the device up on the wall. if desired, the bottom may be closed up entirely, in which case the heat may be made to enter the device by heating the bottom plate. The shields, as seen from Figure 3, may be attached to the bottom or they may be formed of one piece with the bottom plate.

Having now described my invention, What I claim as new and desire to protect by Letters Patent is 1. In a drier a plurality of inverted V- shaped metallic surface plates composing the outside of the drier and a bottom plate with an aperture for admitting a heating medium from afheating device from with out the apparatus, for heating the inner side of said surface plates, their outer side being "used for drying.
