My invention relates to a new and 3111-,

proved type of home dry'cleaning device particularly suited to the rapid and economical dry cleaning of small garments and other textile.fabrics. It is particularly characterized by certain new features which are adapted to permit rapid and inexpensivedry cleaning, the removal of the fluid from the fabrics after dry cleaning, and-filtration of the dirty fluid. One object of my invention isto-produce a device which will permit the use of two ordinary open-mouthed containers as a. dry cleaning system and as described by reference to the accompanying drawing in which:

Figure 1 represents a sectional elevation of. the main portion of the device;

Figure 2'represen'ts a sectional plan view along the line 2 2 of Figure 1; and

Figure 3 represents an elevation of the device, including the containers, at one stage in itsoperation as a dry cleaning system.

the drawing in detail, a

' Referring screw thread 11,-preferably constructed of sheet metal, is adapted to receive corre- 1 sponding screw threads located on the mouth of an open-mouthed container 12. 'A generally similar butfo positelydisposed-screw thread 13 is adapte to receive acorrespond.

ing screw thread. on themouthbf an openmouthed container 14. Screw thread 11 is r to construct the device in such manner that integrally attached to a member 15 and screw threadl3 is integrall vjattached to a member -16; Members .15 an 16 are also in} tegrally attached to each other in such manner as to form a partial partition disposed between screw threads 11 and-screw'ihreads 13. It will be'understoodthat it is possible members 15 and 16 willybereplaced by a single member attached "to both screw threads 11 and-1? In anyevent, members 15 and 16, or a corresponding "similar mam-'1 ber, are perforated as shown at'17 so as to permit the free passage of liquid but not to permit the free passage of fabrics being cleaned. It will be understood that this perforated member may bereplaced by a wide A. JOHNSON, or rmxnmen, mnmors, assren'oa' To sa nitnnan 011.com

meshed screen or other type of foraminous partition.

g In a preferred embodiment the device illustratedin Figures 1 and 2 is used as the cover of the container 12, used for the handling and distribution of dry cleaning fluid. In this case it is, ofcourse, necessary to use.a discoid, impervious and fluid-tight gasket located in the position shown for annular gasket 18 in order to prevent the loss of fluid through perforations 171* In operatingthe system as a dry cleaning device the fabrics to be cleaned are inserted in container 12 and the cover, together with the gasket is replaced, whereupon container 12 is shaken or otherwise. agitated to give efiicient. dry cleaning. It is preferable, v

however, that the cleaning operation be "con ducted, using two containers. In order to accomplish this, annular gasket 18', which will permit the free passage of fluid through perforations 17, is used in place of the discoid gasket previously mention'ed V'ilhe fabrics to be cleaned are inserted in c011- tainer 12, screw threads 11 are positioned on the corresponding screw threads of container 12, and container 14 is placed in position by screwing into screw thread 13. It .is desirable to use a washer or gasket 19 'in order -.to obtain fluid-tight connection between container 14 and screw threads 13. When the two containers have been put in place the wholesystem may be agitated byshaking or otherwise, and the fluid will pass freely back and forth" from container 12 to container 1 1 while the fabrics being cleaned are retained 1n contalner 12. "This insures a morev thorough cleansing action,

since the'cleanin fluid does not travel with the fabrics but 1s repeatedly washed back and'forth through them'. .After the cleaning-"has been accomplished, the device is placed in position, as shown in Figure 3, ,with container 14 lowermost and container 12,;-in which the fabrics. are confined, in

inverted position. By allowing the system to stand 1n this osition the fluld will drain out of the fabrics through perforations 17 into container 14.

The device of my invention has a still further advantage in that it can be used to reclaim the dirty dry-cleaning fluid after the cleaning operation. This can be done by removing container 12, taking out the fabrics, unscrewing the screw threads 13,

and placing a felt pad, filter paper 0r other filtering disc 20 in position agalnst member 16' as shown in dotted form in Figure 1. Screw threads 13 are then repositioned on container 14 in such manner as'to hold filtering disc 20 in position. Container 12 is then replaced in screw threads 11 and the' that it can be sold and used as an independent unit, provided screw threads lland device comprising two open-mouthed containers faced mouth to mouth; an adapter" comprising a perforate partition and attachment meansaflixed to each side of said perforate partition for attachment to each of said two containers; and sealing means forming fluid-tight joints between each of said containers and said adapten' 3. A container for dry cleaning fluid comprising an open-mouthed vessel, a perforate partition, means for attaching said parti tion to the mouth of said vessel, removable imperforate means disposed between said perforate partition and the mouth of said vessel to form a fluid-tight barrier over the mouth of said vessel, and means for attaching said partition to a second open-mouthed vessel disposed in a mouth to mouth position with said first mentioned vessel.

. In witness whereof I have affixed my signature. a

13 are bothadapted to fit the ordinary type of glass container known as a Mason ar. Mason ars are very widely available in pint, quart, and two quart sizes, all having the same standard screw threads. The device of my invention can wellbe made so that both screw threads 11 and 13 will 7 fit these standard Mason jar screw threads and it can then be used by any housewife in conjunction with two Mason jars of suitable size. In any event, it will generally be desirable that screw threads 13 be adapted to fit a Mason jar, and container 14 will commonly be this type of container. Gasket 19 may suitablybe the commercial article known as'a Mason jar ring.

It will be understood that any of the dry cleaning fluids known to the art may be used in my device. Among these may be mentioned naphtha, carbon tetrachloride, tetrachlorethylene, trichlorethylene, s

metrical tetrachlorethane, ethylene dic 10 ride, propylene dichloride and mixtures of any of these.

Although I have described my invention limited except by the following claims:

I claim 1. Anadapter to permit the use of two open-mouthed containers faced mouth to 4 tachment mean aifixed to each side of said
