Patented Apr. 6, 1948 DRYING MACHINE on THE AIR CIRCULAT- mo, ROTARY DRUM, AND ENCLOSING CASING TYPE Elbridgc W. Forney, Canton, Ohio Application September 2, 1943, Serial No. 500,981

2 Claims. (Cl. 34-439) This invention relates to a washin machine- It is primaril aimed to combine in such a machine or produce a single machine orunit which will not only wash clothes but also will enable rinsing, cleaning, starching, and drying of the clothes, without the necessity of removing the clothes from the machine or touching them by hand.

It is further aimed to provide such a machine using a cylinder with novel means for moving the clothes and dropping them, also enabling the admission of air and effecting the pouring of liquid thereon. v Still further it is aimed to provide in such a machine a cylinder with means to rotate it, and means disposed axially thereof at the opposite ends, one of which is capable of. being opened or closed, depending on the particular operation and whether or not air'is to be blown through the machine.

One more important object is to provide a machine wherein through its operation clothes which have been dryed will be ejected automatically.

I further provide novel means for the introduction of water and cleaning materials, for the dissemination of the heat from a motor to the interior of the cylinder or drum, and means for the drainage of water from the machine.

Various additional objects and advantages will become apparent from a consideration of the description following taken in connection with accompanying drawings illustrating an operative embodiment,

In said drawings:

Figure 1 is a view of the improved machine in end elevation;

Figure 2 is a vertical longitudinal section taken 'on the plane of line .2--2 of Figure 1;

- Figure 3 is a vertical section taken on the plane of line 3-3 of Figure 2;

Figure 4 is a vertical section taken on the plane of line 44 of Figure 2;

Figure .5 is a detail section taken on the line 5-5 of Figure 2; i

Figure 6 is a detail section taken on the line 6-6 of Figure 5;

Figure 7 is a detail view partly in elevation and partly in section looking toward the closure for the clothes-discharge opening;

Figure 8 is a detail section taken on th line 8--8 of Figure l;'and

Figure 9 is a detail perspective view of the sediment receptacle used in the washing chamber.

Referring specifically to the drawings wherein like reference characters designate like or similar parts, my improved machine employs a casing generally designated i0 which may be of any suitable size or shape and which preferably is rectangular or square as shown, having depending legs at ll preferably equipped with usual castors l2. A suitable cover or closure is provided at I3, for instance hinged as at M to one side and a handle l6 being used on the cover or closure l 3 to facilitate manipulation.

Suitable aligned openings are provided in two 2 of the side walls of the casing i0, and fastened therein are similar bearing frames IT and i8. preferably of U shape in cross-section with outermost flanges i9 welded or otherwise suitably secured against the outer surfaces of the adjacent side walls.

The other outwardly extending flanges of said bearing frames i1 and i 8 are shown at 20 and are inwardly spaced from such adjacent side walls. Such bearing frames l1 and iii are preferably round, and joumaled thereon for rotation is a suitable foraminous or perforated cylinder 2! in which the clothes or articles under treatment are adapted to be contained during washing or any of the other operations permissible in the machine. Such cylinder 2! has aligned central openings in its ends marginally followed by outwardly extending annular flanges 22, which are preferably thickened by interposed rings 23 fastened thereto, which rings are directly journaled on the bearing frames i1 and I8 overlapped by the flanges 20 and the adjacent side walls of the casing or tub Iii.

Extending inwardly and radially from the cylindrical wall of the perforated cylinder 2i are any desired number of agitators or nozzles 24. These nozzles are of any desired size and generally taper inwardly, being open at the periphery of the cylinder so that water or fluid and air may be collected in the nozzle as the cylinder rotates and may pass therefrom and discharge through outlet openings 25 at a side thereof onto the clothes or other articles.

The clothes or articles to be washed or otherwise treated in the machine are introduced into the cylinder through the bearing ring it. It is to be noted that such. bearing ring is equipped with any suitable closure 26, preferably imperforate and hinged to the casing III as at 21, while inwardly of the closure 28 is an open mesh or perforated closure 28 also adapted to cover the bearing frame i8. Said closures 26 and 28 are capable of individual operation, and each has any conventional latch means to secure it against accidental opening. The closure 28 is hinged at 29 to the bearing ring l8.

Water, detergent materials, starch, or the like may be introduced into the machine through the bearing ring ill or through an inlet as at 29' provided adjacent the top of one of its side walls.

Within the casing l0, beneath and substantially concentric with the cylinder 2i, is a concave bottom 30 which combines with portions of opposite side walls of the casing to form a trough adapted to be filled with water or a cleansing liquid to the level indicated by line 32. A drain cock 33 is mounted in one of said side walls just above the level of the lowermost part of bottom 30 and by which the liquid may be drained from said trough.

A shelf 35 is fastened to the exterior of one side wall of the casing I0 and extends outwardly therefrom; in combination with a hood 36 also fastened to such wall it forms a housing for a motor such as an electric motor 31, access to the latter and adjacent parts being permissible through an opening normally covered by a closure 38, hinged at 39 to the hood and secured in place by a resilient latch at 40 carried by the shelf 35.

The main shaft 4| of said motor 31 has a pulley 42 keyed thereto and also a fan 43 keyed thereto, in line with the opening of the bearing frame H; which latter is covered by metallic mesh, gauze, or the like as at 44. The closure 38 contains an inlet opening for air which is 'drawn therethrough by fan 43 and directed through the mesh fabric 44, through cylinder 2| and out through the opening of the bearing l8, when closure 26 is in an open position,

As perhaps best shown in Figure 4, an endless belt 45 traverses the pulley 42, and pulleys 46 are keyed on shafts 41 disposed parallel to each other and extending across the casing I0 and journaled in suitable bearings 48 in the adjacent end walls of such casing.

Keyed on shafts 41 are pulleys 49 whoseperipheries are in direct driving contact with the periphery of the cylinder 2|. The peripheries of the pulleys 49 may be of rubber or any other material frictionally to engage the periphery of the cylinder, and in order to stabilize the latter each pulley 49 preferably has an outwardly extending flange 50 at one end, overlapping the end of-the cylinder 2 I.

The agitators 24 separate the clothes and prevent their rolling into a ball or bun-die, as well as acting as nozzles to admit water and air freely to the clothes, breaking the rolling orbit of clothes, causing them to separate right and left of the orbit and lifting the clothes and dropping them into the water and in the path of air currents from the fan.

Particular attention is called to the fact that the present machine may be used for washing and cleaning clothes and as well forrinsing clothes, starching them, and drying them, all within the same machine, without removing the clothes therefrom or touching them by hand. When washing clothes the casing contains water to the line 32 so that the clothes will be immersed therein, being pulled through'the same and dropped thereinto through the revolving of the drum or cylinder 2|, the water containing soap or any other detergent desired. At the same time the clothes while undergoing the washing, as well as all other operations, are subjected to the action of air induced by fan 43 and also heated to a certain extent by the motor 31. After cleaning and washing the liquid may be drained through the outlet 33. In rinsing the action is the same, with the exception that only clean water is contained in the casing up to the level 32, and after use may be drained through the connection 33.

In starching the clothes the action is the same as in connection with washing and rinsing, ex-

.4 cept that the water contains a suitable amount of starch. I'n drying the clothes, however, the action is the same as for washing andrinsing, except that no liquids are present, and the door 26 is open whereby the fan 43 drives air'through the cylinder and clothes, agitating therein and out through the perforated or foraminous door 28, carrying moisture therewith. Starch-breaking is effected by the continual agitation or action of the clothes when drying, since such agitation keeps the clothes pliable and does not allow stiifening thereof when drying although they still contain the starch. When the clothes are wet they are too heavy'to be blown out of the machine by the fan 43. However, when the clothes are sufliciently dry they are sufficiently light for the fan 43 to blow them out and expel them through the bearing frame 18, with the mesh or foraminous closure 28 open.

Various changes may be resorted to provided that they fall within the spirit and scope of the invention.

I claim as my invention:

l. A machine of the class described comprising a casing having opposite walls each provided with an opening, a cylinder disposed ,within the casing and having side walls provided with central flanged openings, annular frame members fixed in the casing wall openings and having outwardly opening annular channels for receiving and journaling the flanges of the cylinder openings for rotatably mounting the cylinder in the casing, the opening of one of the flange members providing means for applying'clothes and removing clothes from the cylinder, and a closure for said opening.

2. A machine as in claim 1, means disposed externally of the casing for inducing and directing a stream of air axially therethrough, the other frame member forming an entrance for the air, means for revolving the cylinder, and means disposed internally of the cylinder and'adapted to engage and elevate articles of cloth, contained in the cylinder, and to release said articles so as to be conveyed by gravity across the air stream.
