Application February 9, 1952, Serial 'No. 270,802

1 My invention relates to improvements in clothes dryers. It has for one object to provide a portable extensible clothes dryer wherein clothes are dried in smooth unwrinkled condition and wherein drying is rapidand effective.

Another object of my invention is to provide an apparatus which may serve interchangeably as a Y dryer and as a kitchen table.

Other objects will appear from time to time throughout the specification'and claims.

This application is a continuation in part of my co-pending application Serial No. 167,37 2 filed June 10, 1950, now abandoned. y

My invention is illustrated more'or lessdiagrammatically in the accompanying drawings,

wherein I Figure 1 is a perspective of the device inopen position with the supporting part of the screen;

Figure 2 is a perspective of the devicein the closed position; a l

Figure 3 is a plan view of the open dryer;

Figure 4 is a section along the line 44 of Figure 3;

Figure 5 is a section on an enlarged scale alon the line 55 of Figure 3;

Figure 6 is a section on an enlarged scale along the line 5-6 of Figure 4.

Like parts are indicated by like characters throughout the specification and drawings.

My dryer comprises a rectangular box I having a hinged cover 2 pivotedon one side of the box. It rests on a base 3. Pivoted at 4 on the cover 2 above the hinge is a closing flap 5. The back of the box including the depth of the cover 2 and a substantially equal depth below the horizontal partition e; beneath the cover 2 is cut away. This opening is closed by the flap5 when the cover is in the folded or inoperative position. The cover is hinged at l at both ends of the box'so that it can be folded outwardly from the position shown in Figure 2 to the position shown in Figures 1 and 4. When in this position, screens -8 and 9 bound the upper side of the suction chamber l0 defined within the top of the box and the cover.

l I indicates sharp edged crossmembers projecting upwardly from the cover 2 and the horizontal 18 Claims. (Cl. 34 -239) partition 6 to support the screen. The screen is attached to the outer periphery of the cover and of the box as indicated by the holding clamps 50 held in place by'screws 5| so that the edges of the screen are permanently attached to three sides of the cover and three sides of the box. The abutting edges of the screen are wrapped around angle bars l2 which extend respectively across the box and the cover and are anchored at l2| so that when the cover is in the open position, the elie'ctive opposed edges of the screen abutting being in sufficiently close contact .to permit no passage of solids between them but there {being sufficient clearance so that air may pass upwardly between the members I2. Struts l3 in the cover and struts M in the box hold the'cross members 12 in position against the tension of the screen. Thus there is a continuous generally fiat clothes supporting screen supported in the box'andthe cover and defining the upper portion of the suction chamber 19. These screens are located slightly below the upper level of the vertical walls of box and cover. It is onthis screen that clothes to be dried may be loosely thrown or preferably spread out in one or more layers.

I5 is a suction passage bounded by the outer wall I 6 of the box I on one side and by a vertical interior wall I on the other side. This suction passage communicates with the suction chamber It] and extends substantially from end to end of the box. The wall I1 is centrally apertured and shrouded at Hi to communicate with a motor chamber 19. Contained withinthe motorchamber 19 is an electric motor 20 mounted on a support 22 driving a shaft 23 which in turn carries a suction fan 24.

The intake side of thesuction fan is so associated with the shroud I8 that when the fan is rotated by the motor 20, air is drawn in through the screens 8, 9 into the suction chamber [0 through the suction passage I5, the shroud l8 and discharged into the motor chamber 19, thus exerting a suctionpn and drawing air through the fabric which is (to be dried, supported on the screens 8 and 9.

The motor chamber i9 is bounded on the side opposite to the partition ILthat is on the back of the box as it is in its normal position against the wallfof the laundry by a vertical partition '25 centrally aper-tured and shrouded at 26. ,The

, shroud 26 is so related to the intake side of a second stage fan 21 mounted on the shaft 23 so that air from the motor chamber I9 is drawn by the fan 21into the discharge chamber .28, thence through ports 29 on the side and back of the box 7 so as to insure that the air discharged by the two fabrics to dry, are laid in a number of layers on the screens 8 and 9, and the fans are rotated to exert a suction, the air is drawn through the various layers of fabric, extracts the water from them and accomplishes an exceedingly rapid drying of the fabric. Asmany as nine, ten or a dozen layers of bath" towels can be satisfactorily dried in this manner and since they are laid out in smooth and level condition on the screen, such articles when dried are ready to be folded and put away without ironing. That situation is equally the dried fabrics and the suction drawing air through the fabric results in thoroughly adequate drying without any heating whatever. The arn'- bient air surrounding the apparatus when drawn through layers of fabric, one or more layers, is.

entirely adequate and sufficient to dry the clothes.

When the dryer is in the collapsed position as shown in Figure 2, the flap on the front of the dryer closes the opening between the cover and the case or box. When the dryer is in the open position as shown in Figures 1 and 4, the flap 5 hangs down below the opening and offers no interference whatever.

When the dryer is in the collapsed position of I Figure 2, it makes a sightly, inconspicuous piece of laundry furniture and the smooth top may be used just as any table is used in the laundry. The arrangement is such and the fact that the cover and box are hinged together at two widely spaced points only results in a structure where the screen is tight at all times and when the box or dryer is in the open position, the two screens are in alignment and provide a continuous foraminous supporting surface on which goods to be dried may be placed.

The suction duct [5 extends the entire length of the box and so the entire width of the suction chamber l0. Thus there is an even and smooth flow of air through the goods to be dried through the screen and through the suction chamber l0 to the duct [5.

Under some circumstances it may be that not enough material will be presented for drying to cover the entire combined area of the screens 8 and 8. If this is the case, the fabric mantle 30 wound on a roller 3| is drawn out and laid over a portion ofthe screen so as to furnish a resistance to air flow. It will be understood that drying is accomplished by causing the air to actually pass through the fabric rather than to .pass around it and so if there are substantial gaps left between pieces of fabric, those gaps must be closed. Un-

der some circumstances this canvas 30 may cover only part of the screen. Under other circumstances, experience has taught it is desirable to cover the entire screen, perhaps with clothes to be dried beneath it or perhaps with clothes over it as the case may be.

In order to insure that a sufficient closure over the entire area is provided, I provide also around the outer periphery of the screens 8 and 9, a fabric strip 32 which makes a complete seal with the clothes laid on the screen or with the fabric 30 as the case may be. It will be understood that the fabric 30 and the sealing strips 32 are both of them air pervious. It is not desired to prevent the flow of air, merely to insure a resistance to the air flow throughout the entire area so that the movement of air through the clothes on the entire area will be generally uniform or at least sufficiently uniform to insure a passage of air at high velocity under suction through all the clothes presented to the dryer.

52 is a hand hole registering with a slot 53 in the horizontal surface of the cover so as to provide a smooth and unobstructed surface while making it possible for the operator to reach over and rotate the cover into the operating position. 55 is an aperture in the end wall of the housing enclosing a switch button 56 whereby the motor may be started and stopped.
