This invention relates to apparatus com.- prised in a system for cleansing fabrics of various kinds, especially those of delicate types, by the use of volatile detergent liquids, the invention having reference particularly to apparatus whereby the volatlle liquids may be used safely and without waste of the liquids, either in laundries or other establishments, and be ada ted for using other than volatile detergent liquids.

Objects of the invention are, first, to provide fabric-cleaning apparatus whereby inflammable volatile li uids, recognized in many cases as su erior etergent agents, may be employed wit out danger of explosion and without waste of the liquids; second, to provide apparatus whereby the most delicate fabrics may be cleaned without injury thereto by the use of any suitable detergent liquids or vapors, either hot or cold; and, third, to provide apparatus whereby the cleansin of fabrics, such as carpets, rugs, clothing, bankets, laces, ribbons or other articles, may be accom lished without requiring laborious manna effort in the process.

With the above-mentioned and minor objects in view the invention consists in fabriccleaning ap aratus comprising a renovator consisting of a tightly closed vessel, in which the operation of cleansing may be performed, provided with means for pressing or squeezing or otherwise mani ulating the fabrics, a closed reservoir for t e volatile detergent liquid, a pump for supplying the renovator vessel with liquid from the reservoir, a condenserifor reducing the gaseous fluid from the renovator to a liquid state to be returned to the reservoir, and settling tanks wherein the volatile liquid may be separated from foreign matter resulting from the cleansing operations to be returned to the reservoir. And the invention consists further in the novel parts, and in the combinations and ticularly described and claimed.

Referring to the drawings, Figure 1 is a diagrammatic view showing the dlflerent elements of the invention in sideelevation and connected together in operative arrangement;

Fig. 2, a fragmentary vertical longitudinal sectional view of the renovator showing particularly one form of means therein forsqueezing or presssing the fabrics; Fig. 3, a fragmentary transverse vertical sectional view'of the renovator and the pressing apparatus; Fig. 4, a top plan view of the presslng apparatus detached from the renovator vessel and, Fig. 5, a horizontal sectional view of the renovator vessel and a modified form of pressing apparatus therein Similar reference characters in the different figures of the drawings designate corresponding elements or features.

In a practical embodiment of the invention a closed reservoir A is rovided and placed in any suitable convenient situation,

arrangements of parts as hereinafter paror holding volatile liquid, such as gasolene or the like, to be drawn out as may be required, the reservoir being preferably at a relatively low level so that the liquid must be pumped therefrom.

A renovator com rises essentially a closed vessel B together with suitable means therein for holding the fabrics and for squeezing them in the detergent liquid as part of the v cleaning operations. The vessel may be of any suitable size and shape, and it has a dished bottom a, the ends b and b of the vessel being designed to support thesqueezing apparatus, and the top 0 eing preferably crownmg in form. One side of the vessel has a doorway or opening (2 normally closed b a door e having acklng e and hung on hinges f and f, suitable fasteners 9 being provided for securin the door tightly to the body of the vesse when closed.

The squeezing apparatus may be variously constructed, the referred form thereof com prising a fabric older C having a suitable rame including substantial ends h and h, the end h being provided with a hub 'i, and the end 71. provided with a journal 11 mountedin a journal-box 7' that is secured to the inner side of the end I) of the vessel. The end I) of the vessel is rovided with a packing-box 7c and gland l t at serve together as a journalbearing for a rotative shaft or axle m that extends through the packing-box and is 'detachably secured to the hub i for turning the fabric-holder C over and over, the shaft being provided with a handle n for its control and operation. The fabric-holder has wire-netting sides p and is provided with doors (1 and g at opposite sides thereof having netting or apertured panels 7/, one door bein connected to the frame of the fabricolder\by hinges r and the other door being connected to the frame by hinges r". Each door is attachable at its free edge .to the frame by suitable clasps or fasteners, each of which may comprise a'hinge-part 8 attached to the frame, and a companion hinge-part s attached to the door, there being a pin t for connecting the two hinge-parts together, to be withdrawn for releasing the door. A hook or holder u is mounted in the vessel B, preferably under the top 0 thereof for holding 0 en either the door 9 or the door q when p acing articles into the fabric-holder or removing articles therefrom, the holder being designed to also prevent accidental rotation of the fabric-holder. The vessel B is preferably placed at a greater elevation than the reservoir A, and at any suitable distance therefrom.

A suitable slab D, composed referably of marble or similar stone, is p aced. in the fabric-holder C for pressing the liquid and dirty matter in solution out of the fabric while the fabric rests on either the door q or the door'q as illustrated in Fig. 3, but in some cases the slab may be omitted when from the peculiar nature or condition of the fabric the slab may not be desirable.

A supply-pi e E having a sto -valve F is connected to tlie vessel B and a so to a convenient type of pump G suitably located, there being a suctlonipe E extending from the pump nearly to t e bottom of the reservoir A, for transferring the detergent liquid from the reservoir to the renovator vessel, in such quantity as may be desired, the vessel being provided with gages v and v, for indicating the volume of liquid therein. A gipe H is connected to the top 0 of the vessel and is provided with an outlet valve I through which air may escape from the vessel, or through which air may enter to the vessel as occasion may re uire. The bottom a of the vessel is provide with a stop valve 'w throu h which liquid and refuse matter may be drawn from the vessel. The pipe H is provided with a stop valve J and between the valve and the vessel it is connected by a cross-over pipe y having connection with the pipe E, the pipe y being provided with a stop valve 00 near the pipe E and also with a valve K near the pipe H although in some cases either one of the valves 0; or K may be dispensed with. The ipe 1 may be used if it be desired to pump iquid into the top of the vessel B.

A condenser is provided which comprises nected a a suitable vessel L for holding cooling li uid, and a coil M arranged in the vessel, t lore being a pipe I1 connecting the coil with the valve J. The vessel L is )rovided with a valve L through which cod water may be admitted to and held in the vessel, and an outlet connection L is provided at the .top of the vessel for the escape of water which may become warm and rise in the vessel. A pipe N is connected to the upper part of the coil M and is provided with a stop valve 0. The lower end of the coil is provided with a stop valve P, and a pipe Q of suitable length extends from the valve to the reservoir A. The vessel L is situated at greater elevation than the reservoir, so that there may be gravity flow from the coil to the reservoir.

A pipe R. provided with a stop valve S is connected to the vessel B through which water, either hot or cold, may be conducted to the vessel from any suitable source. Also a pipe '1, having a drain cock 6 enters the lower part of the vessel B and is connected to a radiating coil U that is arranged in the vessel, so that steam or hot water may be introduced into the coil from a suitable source through the pi e T, the end of the coil having a stop va ve 7 from which extends a blow-ofi pipe 8.

A separating tank V is provided and arranged in a suitable position below the lane of the bottom of the vessel B. A pipe T extends-from the pipe T into the. lower part of the tank V and 1s connected to a heatlng coil 'X that is arran ed in the tank, the end of the coil having a b ow-off valve 9. The tank V is rovided with an outlet valve 10 with whlcha suitable pump Y is connected, there being a pipe 11 extending from the pump to the reservoir A and having a valve 12 therein. A pipe 13 is connected to the valve 10 and has a lateral branch rovided with a valve 14 to which a pi e 15 is connected that extends to the tank A valve 16 is connected to the pi e 13 and has a Y-shape pipe 17 connecte( thereto to which is conipe 18 extending to and connected witli the reservoir A. A valve 19 is connected to the'lower end or stem of the pipe 17, and a pipe 20 extends from the valve to a settling tank Z that is rovided and suitably situated so that liquic may flow thereto from the vessel B. A'pipe 21 is connected to the valve 0 and extends to the tank V, being connected to the top thereof and provided with a valve 22 near the top,- although in some cases be dispensed the valve may with.

The separating tank V is adapted to be used for separating the lighter refuse matter from the volatile liquid by heating the liquid so that it may pass off as gaseous vapor, the pump Y to be used for removing any li uid that may remain in the tank after the re use matter settles away from the liquid. The settling tank is adapted to receive the heav ier refusematter from the vessel B to permit the matter to settle down from the liquid, the heavier matter to be drawn off from the vessel before drawing the lighter matter into the separatim tank V. The reservoir A and the tanks Wand Z are provided with suitable wash-out plugs 2 which may be removed for draining the vessels.

In lieu of the s ueezing or pressing apparatus heretofore (escribed, the journal-box i may he omitted from-the vessel B, and a wire-netting fabric-holder 23 may be suitably su )ported horizontally in the vessel B below the plane of the packing-box k. A rod 24 is extended through the packing-box and the gland Z and is provided with a handle 25 at the outer end thereof, the inner end of the rod having a frame 26 attached thereto in which a roller 27 is journaled so as to roll on the holder 23 or over fabric that may be placed upon the holder. Various other specific forms of devices may be employed for the purpose of pressing the detergent liquid from the fabrics during the cleaning operations.

In practical use the process of cleaning may vary somewhat, in some cases it being unnecessary to use volatile liquid. When alkaline detergents may be satisfactory they may be supplied directly to the vessel B through the doorway d or through the,p1pe R, or, if desired, such li uid may be kept in the reservoir A in lieu o the volatile liquid which the reservoir is designed to hold. When it is desired to charge the renovator the door 6 should be opened, then by means of the handle n the fabric-holder C should be turned so as to be horizontal, then the up ermost door thereof should be opened an secured, as in Fig. 3 when a uantity of fabric maybe placed upon the sla D, after which the door of the fabric-holder should be closed and secured. Then the fabric-holder should be turned over so as to be inverted and the other door thereof opened, when the fabric will be under the slab, as indicated in Fig. 3, and then other fabrics may be placed upon the slab and the door closed, after which the door 6 may be closed tightly. N ow the detergent liquid may be supplied in suitable quantity to the vessel B, by either means above mentioned after which the liquid may be heated by means of heated li uid or fluid introduced into the coil U, and w ile the detergent liquid saturates the fabrics the fabric-holder may be turned over again and again so that the slab will squeezethe liquid repeatedly out of the fabric and thereby wash out the dirty matter from the fabrics.

After carrying out the operation sufliciently with the use of volatile li uid the gaseous fluid or vapor from the liqui may be permitted to pass off through the pipe H and 'ing the detergent li uid therefrom.

be condensed in the coil M to pass as liquid to the reservoir A. Also the remaining volatile liquid may be run oil in the same manner if sufficient water he admitted into the vessel B throughthe valve S to float the volatile liquid to the to e; or, the remaining liquid and especially t iat containin'g the dirty matter in suspension, may be drawn oil into either the tank V or the tank Z, and after drawing off the heavier portion of the liquid, the valves 14 and 19 may be closed so that the purer or cleaner liquid may pass through the pipe 18 to the reservoir A. That which may be admitted to the tank Z may settle and the liquid may be allowed to return as gaseous fluid into the vessel B when empty and closed or to the reservoir A. The liquid that may be admitted to the tank V may be heated and vaporized, and the vapor conducted through the pipes =21 and N to the condenser to return to the reservoir A as liquid. Any clear liquid remaining in the tank V may be transferred therefrom by thepump Y and the pipe 11 to the reservoir A, it being understood that the pipe 11 has no connection with the tank Z.

When the modified form of s ueezin a paratus shownin Fig. 5 is rovir ed, the fa rics are to be placed upon t e netting 23, and the rod 24 should be operated longitudinally, thus causin the roller 27 to pass to and fro upon the fa rics, thereby repeatedly s ueez- )ther operations and resu ts will be understood, when not obvious, from the foregoing descri tion.
