Application filed April 18, 1928. Serial No. 831.827.

and exact description of the invention, such.

as will enable others skilled in the art to m which it appertains to make and use the same, reference being had to the accompanying drawings, and to the figures of reference marked thereon, specification.

This invention relates to clothes driers and the primary object thereof is to, provide an improved form of clothes drier so constructed that the clothes may be contained within a clothes chamber through which atmospheric air may pass, the air being heated by a heater having ducts sur-- rounding the clothes chamber but in communication therewith. This is important since the clothes will absorb the fumes of x the products of combustion whereever they come into contact and experience has taught that whereever the products of combustion contact with the clothes, the clothes show the result of such contact, particularly if white W goods is being dried.

It is an im ortant feature of my invention that the ow through the heating ducts be relatively slow to permit the clothes chamher to absorb the maximum B. t. u.s from as the products of combustion before they pass to atmosphere.

lit is understood that only atmos heric air comes into contact witlr" the clothes from which the moisture is being evaporated.

- 4 Therefore, the heated atmosphere has a more or less sterilizing efiect on the clothes and leaves them sweet and clean when they are taken from the clothes chamber.

ll have'provided means for retarding the flow of the products of combustion through the heating ducts and these can be so arranged that the rate of flow of the heated. air can be such that the maximumeficiencyv will result. o v v I havezalso constructed the clothes drier so that the clothes chamber will be uniformly heated throughout, this bein important so that all of the clothes can e dried at the same time rather than to have local 5 application of heat at difierent parts of the which form a part of this .ered by adeck12sp closed by the doors clothes chamber, it being apparent' that if the clothes chamber had va iable heat zones, some of the clothes woul dry while the vice would be unsuitable for practical use.

I have also provided means whereby the clothes'can be'introduced into the clothes chamber in a convenient manner, there being racks in the clothes chamber which may be extended outside the ,drier to receive the clothes preparatory to their introduction into the drier. r

' The novel construction of the invention will be apparent by referenceto the followmg description in connection with the ac-' companying drawings, in which- Fig. 1 is a perspective view of a clothes drier constructed in accordance with my invention, parts being broken away to show thefheat ducts, the air inlets for the combustion chamber, and the rack for holding the clothes.

others would still remain wet. Such'a de- The casing is shown as substantially rectangular having sides land 2, a back? and an open doors 5. and 6. The doors may be fastened by suitable bolts 7 and 8 operated by a swingingthrow lever 9 controlled from the outside of the drier.

The drier is also provided with a top 10 havingan elongated slot or opening 11 covaced away from the top so that outlet opemngs are provided,

Within the casing is a clothes'chamber also substantially rectangular. It consists of side walls 15 and 16, and an open front and is accessible throu h the opening t 5 an 6. The top 18 of the clothes chamber is provided with a longi-- tudinally disposed opening or slot 19 with the slot 11 so that the air through haus't thro htheopenings 13 and 14. The walls 15 an 16 of the clothes chamber, extend from the front to therear. of the cas ing and they are spaced from thew 1;

assin'g front 4, adapted to be closed by'the or spaces 13 and 14:

in l ne the clothes chamber can a so exand 2 to provide longitudinal spaces 20 and 21 which are co-extensive with the length of the drier.

The bottom 22 of the clothes chamber is located a substantial distance above the bottom 23 of the casing to provide a space 'divided into two subjacent chambers 24 and 25.. The subjacent chamber 25 is the combustion chamber and it has located therein a burner 26, by means of which the bottom of the chamber 24can be heated. The bottom 23 for the combustion chamber is provided with a plurality of air inlet openings 27, admitting only enough air to support the bottom combustion. This air is heated in the combustion chamber. 25 and slowly passes up the ducts or spaces 20 and. 21 and out through the converging spaces 29 and 30 to the exhaust spaces 13 and 14.

The top of the clothes chamber converges slightly toward the top of the casing so that the spaces 29 are slightly restricted to tend to hold back the products of combustion and, therefore, retain them for:.the maximum time in the ducts, allowing the air in the clothes chamber to absorb 'the maximum amount of heat to evaporate the moisture from the clothes.

. The bottom 31 of the fresh air chamber 24 is provided with upwardly converging portions 32 and 33 againstwhich the products of combustion first contact so that the hottest part of the bottom of the fresh air chamber will be at the center.

The ends of the casing are provided with fresh air inlet openings 34 and 35 whereby fresh air may be admitted into the fresh air chamber 24 and then pass through the openings 36 in the bottom chamber. Theifresh air passes up through of the clothes chamber and con tacts with the clothes supported on the drying racks and then passes out through the port 19.

The clothes can be supported on a rack structure consisting of a triangular bracket having downwardly converging frame members 38 and 39 at one end and 40 and 41 I at the other. The members 38 and 40 are connected by guide rods 42 and the members a 39 and 41 are connectedwith similar longitudinal guide rods 43. These support the clothes-supporting bars. The clothes-supporting bars .are designated 44 and they carry hooks 45 and 46. The hooks 45 may be closed around the supporting guide rods 42. The hooks 46, however, will be open to engage over the hooked ends 47 of the rods 42 so that the hooks 46 can be removed from the ends 47 to permit the clothes-supporting v rods or bars 44 to be slid outwardly through the opening in the drier.

have provided a bar-supportin rack for holding the bars 44 in their exten ed positions when the clothes are being drled.

plate 22 of the clothes so that the member 49 cannot be pulled out of the guide 50 whichis shown in Fig. 5.

When the parts areassembled and the burner is lighted, the doors 5 and 6 will be opened, the clothes bar-supporting rack will be extended" as shown in Fig. 1 and one of the bars 44 will be drawn out to the position' shown in Fig. 1 with its forward ends supported on one of the projections 52. The clothes will then be applied to the bar 44, the bar will be slid back into the drier and the hook 46 will be hooked on one of the projections 47. Then another bar 44 will be extended to receive the clothes and in this way the clothes-supporting rack will be filled. Then the clothes bar supporting rack will be ushed back into the drier and the .doors 0 osed. The heat generated in the combustion chamber 25 will pass up through the ducts 20. and 21 at a relatively slow. rate and the products of combustion will be slowly choked between the two top members 18' clothes chamber will be uniformly heated and the hot air will pass through the clothes and out through the neck or opening 19. During the passage of the heated air, the moisture will be evaporated from the clothes and in a relatively short time,&the clothes will be completely dried.

Since the products of combustion do not come into contact with the clothes, it is obvious that they will not have the odor of the burnt gases and I have found in actual experience that by segregating the products of combustion from the alr which comes into contact with the clothes, white clothes bleach out without any appearance of yellowness which is sometimes observed in clothes dried by artificial means.

The air removes any odor from the clothes as all of the wash water is evaporated and the fact that fresh air passes through the clothes after they are dried and at a high temperature insures their being thoroughly aerated and practically sterilized.

naoo ea The device is simple in construction, inexpensive to manufacture and will efiiciently perform the functions for which it is intended. I

What I claim and desire to secure by Letters-Patent is:
