9 Claims. 1

My present invention relates to laundering apparatus, and more particularly to such an apparatus suited to domestic or commercial use including dry cleaning and the like.

One of the objects of my invention is to provide a laundering apparatus by which articles to be cleaned are held in shape during the washing and drying operations.

Another object of the invention is to provide a laundering apparatus wherein shrinking or stretching of the washed articles is minimized.

It is a further object of this invention to provide a laundering apparatus in which articles of different colors may be washed at the same time, but kept separated so as to prevent fading from one to another.

My invention also has for an object the provision of an apparatus for laundering articles in such a way that the washing and drying are successively accomplished in a single machine and the necessity of separately ironing the articles is eliminated.

As another object, the invention comprehends the provision of an apparatus for laundering articles without breaking buttons or tearing them off, as often happens in the usual processes and apparatus for laundering.

The invention has for another object the provision of laundering apparatus of the character described which may be constructed as a unitary assembly having a neat appearance.

Other objects and advantages of the invention will be apparent from the following description and the accompanying drawings in which similar characters of reference indicate similar parts throughout the several views.

Figs. 16, 1'7 and 18 are side elevational views of three complementary sizes of parts of the laundering apparatus like that shown in Fig. 3.

In the exemplary embodiment of my laundering apparatus disclosed in the accompanying drawings, I have shown its adaptation to a cabinet 20 as depicted in Figs. 1 and 2. In this cabinet a laundering tub 22 (Fig. 4) is mounted near one end and closed by a cover 23. Although optional, I have provided folding top leave-s 24 and 25 which fold inwardly against the topof the cabinet, as shown in Fig. 1, when the apparatus is not in use for laundering, and extend outwardly at the ends of the cabinet to provide bench space during the laundering operation. For supporting the leaves when extended, folding brackets 26 and 2'! are provided at each end of 'the cabinet and are hinged to fold against the end of the cabinet when the apparatus is not in use and project outwardly from the cabinet ends to support the leaves, as shown in Fig. 2.

3 By preference, compartments 28 are provided within the cabinet for the storage of laundering material and the like, which compartments are.

normally closed by

doors

29 and 33.

In the disclosed embodiment of my invention, the laundering tub 22 has a substantially cylindrical side wall 32 and a substantially flat bottom 33. At the mid-portion of the bottom 33 of the tub, a hollow spindle housing 3 extends upwardly within the tub to a position above the normal liquid level in the tub. The spindle housing is' tubular and open at both ends. Within the housing 34 a hollow spindle 35 is journaled for rotational movement by bearings 35 and 31 disposed near the opposite ends of the housing. At its upper end the spindle 35 has a polygonal driving portion 38 which projects axially therefrom; while at its lower end the spindle extends outwardly from the housing and is drivingly connected to a driving mechanism comprising a gear box 39.

For driving the spindle, gears which may be of a conventional type enclosed within th gear box 39 are driven by a prime mover such as a motor til through driving instrumentalitie-s which, in the present instance, are indicated as

pulleys

42 and 53 and a belt 4 which encompasses the pulleys. By preference, the gears within the gear box 39 are so constructed and arranged that the operation of the spindle may be controlled by the manual actuation of a shift lever 45 having a handle 46 exposed within the cabinet, as shown in Figs. 4 and 5. Preferably,

the handle 46 has three operating positions; an I off position in which the spindle is stationary although the motor is operating; a wash position in which the spindle is driven with an oscillatory movement, traveling part of a revolution in each direction; and a spin position in which the spindle is rotated at a speed sufiicient to throw washing fluid from the washed articles by centri- At itsupper end the spindle housing 34 is provided with amp 5%? which surrounds the extending end of the spindle 35 and closes the upper end of the spindle housing. At the upper end of the spindle and above the cap 59, a plurality of air passages 52 are drilled radially through the side wall of the hollow spindle in circumferentially displaced positions. An air pipe 53 extends upwardly through the gear box 39 "and to a position within the hollow spindle which is desirably above the normal liquid level in the tub. The air pipe 53 communicates with a heater 5E and a blower 55 so that when the blower and heater are turned on, heated air is forced upwardly through the pipe 53 and outwardly through the air passages '52 at the top of the spindle. A switch 555 is conveniently disposed within the cabinet, "as shown in Fig. 5, for controlling the operation of the heater and blower.

At one side of the spindle housing in the bottom or the tub a drain opening 5? is provided and is controlled by-a drain plug 58 actuated by a manuany operable control k-nob'59 within the compartment 28 of the cabinet. 7

A Agyrator 68 has a hollow cylindrical portion 62, the'internal diameter of which is larger than the external diameter of the spindle housing. At its lower end the gyrator has an outwardly extending base flange 63, the external diameter of which is somewhat smaller than the internal diameter of the tub. The upper end of the hollow cylindrical portion 52 of the gyrator is closed except for a central polygonal opening 65 which fits onto the polygonal driving portion 38 of the spindle and rests against a shoulder 65 on the spindle to support the gyrator with its base flange 63 spaced from the bottom of the tub. A plurality of circumferentially spaced fins 65 project outwardly in a radial direction from the cylindrical portion of the gyrator at circumferentially spaced positions. By preference, the fins 66 are substantially flush with the top or" the cylindrical portion of the gyrator and taper outwardly toward the bottom, with relatively thin rib portions 61 at their lower ends which extend outwardly to the outer edge of the base flange 63.

Between the fins 66 slots 63 are provided in the cylindrical portion 62 for the passage of air when the blower is in operation. The shoulder 65, upon which thetgyrator rests, being above the air passages 52 in the spindle and the internal diameter of the hollow spindle portion 62 of the gymtor being larger than the spindle, heated air from the pipe 53 passes through the passages 52 into the space between the gyrator and spindle housing and flows outwardly through the slots 68 and beneath the gyrator for drying purposes after the laundering has been completed and the tub drained.

Rather than to throw the articles promiscu'ously into the tub for laundering in the usual manner so that they are crumpled and wrinkled during the laundering process, it is one of the features of my laundering method and apparatus that the articles are held in a smooth state during the entire laundering process. By thus holding the articles smooth and in their finished stat during the laundering and until they are thoroughly dried,. they are not only subject to thorough cleaning but the necessity of ironing all or a large number of the usual articles of household laundry is eliminated.

For the purpose of holding the articles of laundry in a smooth state during the laundering operation, and in the presently disclosed form of my invention, I have provided a plurality 'of cylindrical drums l0 and 12, as shown in Figs. 3, 4,6, 9, 16, 17 and 18, which are of sizes adapting them to nest together in concentric and spaced relationship within the 'tub 22. Except for their dimensions, the structure and relationship of parts of each of the drums are similar to the others so that a description of one will suffice for all, with the understanding that like reference numerals refer to the similar parts of the various drums. The main supporting structure of each drum comprises a cylindrical side wall 13 of perforated sheet material such as metal, plastic, screen or the like, open at one end, as shown in Fig. 4, and having secured to its other end a cross type of supporting web I'M, at the center of which is a spacing insert the endof the side wall. The ring 18 is notched at circumferentially spaced positions corresponding to the spacing of the fins 66, as shown in Figs. 16, 17 and 18; the notches being of a size to fit over the rib portions 61 of the fins. When the spacing inserts I of the drums are placed upon the driving portion 38 of the spindle in their proper position according to the sizes of the drums, the reinforcing rings I8 engage the base flange 63 of the gyrator to provide additional support for the drums, and the engagement between the rib portions 6! and the notches '19 of the reinforcing rings 18 provide additional driving connections between the gyrator and the drums.

Thus, when the spindle and gyrator are driven with either the gyratory or circular motion during the washing or spinning operations, the drums are driven therewith. The articles to be laundered are placed smoothly over the outer surfaces of the cylindrical side walls I3 of the drums. In order to aid in placing and securing the articles BI) which are to be laundered, upon the surface of each drum, as indicated in Fig. 9, I have provided in my disclosed embodiment of the invention a multiplicity of relatively fine short pins 82 which project outwardly from the outer surface of the cylindrical side wall an are intermingled with perforations 83, and upon which pins the articles of various sizes and shapes will be held.

I In addition to the pins for holding the articles in place upon the drum during the laundering operation. I have provided a plurality of segments 84 of perforated sheet metal, plastic or the like which conform to the curvature of the outer surface of the drum and are circumferentially spaced substantially to cover the outer cylindrical drum surface with axially extending divisions between the segments. Each segment is secured to the lower edge of the drum by a hinge 8-5, which hinges allow movement of the segments from a position contiguous to the drum surface to a position axial to the drum at one end thereof, as shown in Figs. 3 and 9. In the open position in which the segments extend axially from the open end of the drum, the cylindrical outer surface thereof is exposed for the placement or removal of articles.

When articles are placed upon a drum for laundering, they are stretched smoothly over the drum surface with the pins 82 projecting into or through the cloth. If an article is larger than the drum in an axial direction, it is folded to fit the drum in length. Circumferentially, the articles are wrapped around the drum. If an article is too long to be accommodated by the drum in a single turn, it may'be wrapped so as to overlap.

It may be readily understood that with the disclosed structure, the smaller articles may be so placed as to be held separately and in spaced relationship to one another. After placement upon the drums, the segments are folded to their closed position in which they overlie the outer surface of the drum and the articles thereon. This additionally secures the articles in place and holds them in a smooth state during the laundering operation. Manually operable clips 86, which, in the present instance, are indicated as swingably supported studs 81, fit into slots 88 at the ends of the segments 84. They are provided with cooperating nuts 89 which are tightened to secure the segments in their closed positions, as shown in Figs. 3, 7 and 8,

Any number of drums, up to the machine capacity of the particular laundering apparatus,

may be used at any one time to hold the articles to be laundered. In the disclosed embodiment of my invention, the capacity of the apparatus is three drums. As shown in Figs. 4 and 6, these drums are spaced radially of the gyrator and tub. When the washnig operation is in progress, the gyrator and the drums are both moved with an oscillatory motion, which motion together with the action of the gyrator fins upon the washing liquid, forces the Washing .iluid through the perforations of the drum side walls and segments and through the articles which are carried thereby. The cleaning of the articles is thereby efiected. After washing, the cleaning liquid is drained from the tub and the drums are spun to force the cleaning fluid therefrom by centrifugal force. With a large part of the cleaning fluid thus removed and either while the drums are being spun or while they are stationary, the blower and heater are turned on to force heated air through the perforations in the drums and the articles until they are completely dried. Being cleaned and dried while they are held in a smooth state, the necessity of ironing many or all of the articles is ,eliminated or, at least, the labor of ironing is very materially reduced by the initial smoothness of the articles.

The drums 69, 10 and I2 are separately insertable and removable from the tub by placing or lifting them in order of size when the cover. 23 .is removed. For convenience in handling the drums while they are being loaded or'unloaded, I have provided a support on the top of the cabinet for holding the drums in a horizontal position, as shown in Fig. 9. In the present embodiment of my invention this support includes a metal strap 95 slidable vertically in a channel 92 secured to a wall 913 f the cabinet and adapted to be secured in an adjusted position by a thumb screw 84 which is threaded into the strap and rides in a longitu inal slot in the channel 92., At its upper end the strap 90 carries an antifriction bearing 96 having its outer race secured between a shoulder 91 and a retaining ring 98, which ring is held in place by fastening means, such as screws 99. The inner race is secured to an axially projecting polygonal fitting It!!! by a screw IE2; the polygonal fitting I90 being adapted to fit into the central openings I6 of the retaining rings at one end of a drum. The extended height of the strap in each instance is adjusted to suit the size of the drum. When the strap is not in use for holding one of the drums, it and the polygonal fitting IGG are retractable into an opening Ill-3 (Fig. 2) in the top of the cabinet.

For supporting the other end of any one of the drums while it is being loaded or unloaded, I have provided a channel type bracket I04 which has one end connected to the cabinet by a hinge I05 adjacent an opening its in the surface of the folding leaf 25. At spaced positions, the bracket I04 rotatably supports rollers I81 which engage the outer surface or" the drum at the end opposite the strap 90, providing asupport which permits rotary movement of the drum. When the rollers are not in use, the bracket I64 is folded into the opening I36 in the leaf 25 to an out-of-the-way position in Which the exposed surface of the bracket is desirably flush with the surface oft-he leaf.

From the foregoing description of my laundering method and of the structure and operation of the exemplary type of laundering apparatus which is disclosed herein, it may be readily understood that many advantages grow out of th'ehold-j ing of the articles in a smooth state and in fixed relative positions during the laundering operation. Such articles are not only heldin shape during the Washing and drying, but shrinking and unintentional stretching of the washed articles are minimized. The washing and drying are successively accomplished in. a single ma.- ch'ine and Without the necessityof passing the artiolesthrough a separate wringer or even moving them until they are completely washed and dried. Ironing of many or allofrthe laundered articles is eliminated. Furthermore, there is nothing-about the apparatus or its use which has any 'tendency'to break buttons or tear them from the material to which they are .fastened. These many features are provided .by laundering apparatus which is adaptedto construction as a unitary assembly having neat appearance as well as utility. It is understood'and is hereby emphasized that although the disclosed apparatus incorporates a gyrator for effectively circulating the cleaning fluid through the articles during the washing operation, there may be instances in which other structure or arrangements may be utilized while still maintaining the advantages of holding the articles in asmooth state during the laundering. It is also to be noted that by the smooth and compact placement of the articles in prearranged positions on. thedl'ums, a large-volume of laundry may be handled in any one laundering operation of the apparatus.

While I have'illustrated a preferred embodiment of my invention, many modifications may be made without departing from the spirit of the invention, and I do not wish to be limitedzto the precise details of construction set forth, but desire to avail myself of all changes within thescope of the appended claims.
