WASHING APPLIANCE FOR SMALL AND DELICATE ARTICLES Oct. 1, 1963 2 Sheets-Sheet 2 Filed May 4, 1962 INVENTOR fume-A $54577 United States Patent 3,165,376 WASHHQG AfPLlANQE FUR SMALL AND DELHZATE ARTl-CLE Elmer Haslett, 7W7 Groton Sh, Forest .liiis, NE. Filed May 4, i962, Ser. No. ESZJBEE 13 Claims. (1. 68Zl3) My invention relates to a device useful for washing very delicate and fragile things, such as sheer hosiery.

As is well known, most hosiery of silk, nylon, rayon, or other composition is generally washed by hand in basins, the sheerness and delicacy of these items being so great that the violent agitation of an ordinary mechanical clothes washer plus the abrasive action of contact with heavier and rougher articles and fabrics often causes tears, snags, and runs. Likewise, there is always the danger or tendency to damage, deterioration, distortion and shrinkage from excessive temperature exposures in washing these delicate things with other fabrics. Separate meshed bags for the protection of these delicate things when washed mechanically with other things are available with some improvement. While these delicate things are thus much safer when washed by hand in the basin, another danger is always present in that a rough edge of a basin stopper ring, a nicked edge of the basin drain, a rough fingernail, hangnail, or even badly chapped skin can cause rims and tears. Also, over half our Nation has hard water. And in washing both by machine and by hand in hard water, one of the biggest problems is that of soap curds. These soap curds (the familiar ring about the bath tub) result generally from coagulation: the chemical reaction of soluble calcium carbonate or magnesium carbonate with soap. The degree of this coagulation depends on several factors, but where heavy curds are present, they coat and adhere to the stockings or other items, destroying the sheen and lustre as well as lodging within the pores a foreign chemical agent for shortening the life of hosiery. The soap curd problem, while quite general, is less where certain detergents are used, or where water is previously softened by zeolites or other chemicals. On the other hand, many skins are allergic to deergents; and 50' mild soaps are used by preference.

Objects of the invention are to provide means useful for washing and rinsing very delicate, sheer and fragile items, such as ladies sheer hosiery, with which the danger of snags, runs and other damage to such items during washing and rinsing is substantially eliminated, with which such items are entirely insulated and protected from damage during washing and rinsing, and protected from contact with any sharp, rough, rigid or other surfaces that might tend to tear, snag, distort, or cause runs to occur in such items, which will act as a filter for the cleansing and rinsing solutions to prevent contact of coagulated soap curds with the items being washed and/or rinsed, and which will be relatively simple, compact, effective, practical, convenient, and inexpensive.

Other objects are to provide means for washing and rinsing delicate and fragile items, in the use of which for washing and rinsing such items, the hands of the user may be protected from the washing solution and rinsing water, and which enables the rapid and effective washing and rinsing of such items.

Other objects and advantages will be apparent from the following description of embodiments of the invention and the novel features will be particularly pointed out hereinafter in connection with the appended claims.

In the accompanying drawing:

FIGURE 7 shows another embodiment of the invention, with a hollow ring aflixed to the lid portion to fit within the top of the cylinder and function somewhat like apiston.

In the embodiment of the invention illustrated in FIGS. 1-6, I use as a container a substantially hollow, completely enclosed, elongated cube or block of unicellular, absorbent, porous, elastic or resilient, or foam material such as foam rubber, cellular polyester resins, polyurethane resins or materials having equivalent properties. The material used must have the properties also of being compressible, flexible, pliable, stretchable with the important inherent characteristic of restoring itself to its original shape after being temporarily distorted by compression, squeezing, or stretching. The unicellular material has many small cells within its interior communicating with one another from surface to surface, and hence is functionally the equivalent of one single, extensive, cellular network. As a result it is absorbent and porous, and liquids can pass through its walls. This is important so that liquids may pass through its walls rather freely. Among these materials, the unicellular and therefore porous and absorbent polyurethanes are highly satisfactory for this purpose.

Referring first to the embodiment shown in FIGS. 1-6, a right or regular parallelepiped shaped container or block 1 of elastic, cellular, porous material has a slit or cut 2 (FIG. 2) that extends parallel to and spaced from one end from one side nearly to but short of the opposite side,

that is not entirely across the container or block so as to leave an uncut area 3 that serves as a hinge for the end part above the cut 2. This part 4 functions as a cover which may be swung from the closed position of FIG. 2 to an open position such as shown in FIG. 1. While the cover 4 is in an open position, a cylindrical hole 5 is formed in the block 1 below the cut 2 and term nating somewhat above the bottom end face, so as to leave a continuous and unbroken but porous bottom wall 6.

The cover 4 also has a narrow, annular groove or chanml 7 (FIG. 3) formed or cut in its inner face and terminating short of the other, outer end face of the cover. The inner diameter of the channel 7 is that of the diameter of the hole 5. Secured across the portion of the entire inner face of the cover which is encircled by the annular groove or cut 7, is a disc 8 of water impervious, elastic, preferably flexible material, such as of rubber sheet material for example, this disc being confined, such as by cement, flat against the inner face of the cover. The diameter of the disc 8 is equal to or slightly less than the diameter of the channel 7 so that when the cover is closed, the disc 8 may enter and extend substantially across the upper open end of hole 5, as shown in FIG. 3.

Superposed on the exposed face of disc 8 is another disc 9 of sheet material that is inert to water and detergents, and which has a periphery with notches therein for both ornamental and useful purposes. The overall diameter of the disc 9 is preferably slightly greater than the diameter of hole 5 so that the notched margin will be deflected slightly as it enters the upper end of the hole 5 and provide friction to hold the cover in closed position. These discs act as projections that enter the upper end of hole 5 and center the cover properly with respect to hole 5.

When the top of the container or block so made is depressed in use, as hereinafter explained, the discs 8 and 9 will guide the part of the inner face of the cover that is encircled by the channel 7, and which is in effect a piston recessed in the inner face of the cover, down into the upper end of the hole 5 and thus prevent any lateral displacement of the cover on the body of the block which might damage the hinge portion 3 or open the hole 5.

The exterior bottom face of the container or block I. has a cavity or recess 10 in its central face area, which does not extend into the hole 5, and this recess it may advantageously be defined by an arcuate wall as shown. A disc 11 of Water impervious, flexible and preferably elastic sheet material is confined, such as by cement, over its face area against this wall defining recess fl), as shown, so that it acts as a water impervious liner for the recess. This disc 11 has an aperture 12 approximately centrally thereof and of substantial size. An ornamental flower or other ornament 13 may be afiixed to the top or outer face of the cover, and a suction cup 16 (FIG. 2) may be afiixed to the top or a side wall of the container, such as to the rear side wall thereof, by which the block or container maybe detachably confined by suction to a wall or tile of a room when not in use in washing articles, and washed stockings or delicate articles of wear may, for drying, be draped over the block so held to a Wall.

In the embodiment of the invention illustrated in FIG. 7 the construction is similar to that shown in FIGS. 1-6,

except that-instead of having the annular channel 7 and the discs 8 and 9 of FIGS. 1-6, a boss 14 having an outside diameter approximately equal to the diameter of hole 5 is fixed, such as by cement, to the inner face of the cover in a position to be aligned with and enter the upper open end of hole 5 when the cover is closed, and prevent sidewise movement of the cover when the block or container is compressed in use. While this boss 14 may be a cylindrical boss or projection, it is illustrated as an annular ring cemented to the inner face of the cover. In either event a ring 15 of water impervious sheet material is confined, such as by cement, to the center of the boss 14 or within the annular ring, so that water or detergent may not pass upwardly through the center portio not the cover when the block is compressed while partially immersed in a liquid.

In one example of use, nylon stockings or other items to be washed are placed in the hole 5 while the cover 4 is open, and then the cover is closed. A quantity of water and detergent or soap forming a warm sudsy solution about 2 inches deep is placed in the basin of a wash bowl A (FIG. 5) and then the block or container 1, with the items therein, is placed upright in the basin as shown in FIG. 5. Then one compresses the cover, as shown by the hand in FIG. 5, like an accordion and releases it repeatedly. When the block or container is compressed in this manner against the bottom of the container the conporous bottom wall 6 of the block into the chamber or hole 5 where it contacts and passes through and around the stockings or items contained in the hole 5. During this compression of the block to approximately half of its normal height (FIG. 5) air in the hole 5 is expelled through the porous side walls of the block. This expulsion of air from hole 5 is greatly accentuated by reason of the fact that the water impervious disc 3 (FIGS. 1-6) (or ring 15 of FIG. 7) moves down the hole 5 during the compression of the block and acts as a piston in hole 5 to expel air therefrom.

When the hand or fist releases the container or block, the collapsed block resumes or returns to its original shape and size, due to the inherent resiliency or elasticity of the material of which the block is formed. As the collapsed block returns to its original shape and size, the partial vacuum created in hole 5 by its enlargement due to such return to size, causes sudsy water to be drawn through the side and bottom walls of the container into the hole 5 to fill it in place of the previously expelled air. Each additional compression of the device against the bottom of the basin forcibly pumps sudsy water in from the recess 1% in the bottom of the block, and expels other sudsy water from the hole 5 with considerable force through the porous side walls of the block. The pressures on the liquid in the hole 5 creates jets or streams of sudsy water that pass through aperture 12. and penetrate and pass around the fabrics in the hole, which is the most eflicient manner of washing fabrics. The aperture 12 concentrates some liquid into a defined stream passing through the bottom wall of the conta ner.

During compression or collapsing of the block or container by downward hand pressure on the cover, the part of the cover encircled by the channel 7 moves down into and somewhat along the hole 5 as a piston to prevent sidewise movement of the cover 4 on the block 1, which prevents loss of textile material from the hole 5, dam-age to the hinge portion 3 of the cover, and possible entry of soap curds into the hole 5. When not in use, the discs 8 and 9 (boss 14 of FIG. 7) keep the cover closed by friction of the periphery of disc 9 against the side wall of hole 5.

The shape of a right or regular hexahedron or right or regular parallelepiped for the block 1 witha cylindrical hole 5 is advantageous because the larger thickness of the side wall at the upright corners gives more body to the block that assists in increasing the resiliency of the material and provides a more rapid return of the block to its normal shape after compression and release. The thinner portions of the side walls between the corners offer minimum resistance to the free circulation of cleaning solution or rinsing liquid during compressions and releases of the block. The porous walls of the container act as filters to prevent entry of any soap curds into the hole 5 and contact there with the items being washed.

After the items have been washed in this manner in a sudsy water, the block with items therein is removed from such water and the compression and release operation again repeated with plain or rinsing water to rinse the items while still in the 'hole 5. The items may have excess liquid expressed therefrom by removing the container with items confined therein from the liquid, and then squeezing the container between the hands as shown in FIG. 6. This squeezing may be performed after the washing in a detergent and before rinsing, and also after rinsing so that the items will then only be damp when removed from hole 5 for drying. This facilitates drying.

Since the basin of sudsy water 'or detergent solution need only have a depth much less than the height of the block or container, the washing and rinsing operations can be performed without the hand coming into contact with the detergent or rinsing water. This avoids damage to manicure of the skin and nails of the user. Of course, if one does not object to having the detergent or rinsing water contact the hands, the washing and rinsing liquids may be much deeper, even to a depth greater than the height of the container 1. While use of detergents and sudsy water for the cleaning has been described, other cleaning agents that do not damage the material of the block or container may be employed, so that limited, so called dry cleaning of delicate items is possible with this invention.

The rinsing operation can also be performed by holding the block or container 1, with its cover open, directly under a faucet and allowing clean water to flow into hole 5, with some of it overflowing and some or all of it passing through the porous side Wall of the container. Also by placing a rubber band or string around the container and over the cover, while the items to be washed are confined within the hole 5, the container with its cover so held closed may be placed in a mechanical washing machine and the items washed alone or with other laundry, without danger of damage -to the items. The action of the washing machine in tumbling the container about in the washing chamber will alternately compress and release the container so as to cause flow of the cleaning solution through the container walls and through and around the items in the hole 5.

While the device is especially useful in washing or cleaning delicate textile items such as sheer nylon stockings, it may also be used to clean other delicate items. It will also be understood that various changes in the details, steps and arrangements of parts, which have been herein described and illustrated in order to explain the nature of the invention, may be made by those skilled in the art within the principle and scope of the invention, as expressed in the appended claims.
