ART OF AND MEANS FOR DEOZDOIBJIZIN'G FABRICS AND GARMEN'I'S OLEANBED BY .VOLA'IILE LIQUIDS.

Application med lay 5,

To all whom it may concm:

Be it known that I JOHN J. JnNKINs, a

citizen of the United tates, residing at Los Angeles, in the county of Los Angeles and State of California, have invented a new and useful Improvement in the Art of and Means for Deodorizin Fabrics and Garments Cleansed by V0 atile Liquids.

In the art as heretofore practiced, it has been customar to clean fabrics, wearing natural moisture ori 1819. Serial N10. 295,016.

nection in the. rear to'allow steam at acertaln pressure to enter 'the'outer shell, thus forming a blanket of steam and at the same time, replacing the molecules of volatile solvents left in the textile fabrics or fibres by the moisture produced by the condensing of the steam eliminating fire risk, rejuvenating the textile fabrics or fibres, replacing. the 'nally contained in these, before the had een subjected to the apparel, and t e like, by washing with or action of the V0 atile solvents, giving them immersing in a volatile liquid such as pethe proper feel or hand and making troleum distillates wood naphtha, benzol, these textile materials absolutely odorless. carbon tetrachlori e, and other liquids of a like nature.

After this step in the process, the textile l sists in treatihg the fabrics in the drum for a period with a blanket of live steam and then to drive off the live steam by hot air, and an object of this invention is to provide simple means adapted to serve this purpose and to be easily applied to old and also to newdrying apparatus in which the revolvin drum is used.

he invention is broadly new, basic and pioneer in that I apply to the fabrics to be dried and deodorlzed, a blanket of live steam as distin ishedfrom a mixture of steam and hot air; and this I do by providing within a narrow portion or neck of the hot air ipe a perforated steam pipe so constructe connected and arran ed that when the steam is turned on in sue pipe ..it will practically exclude air from the portion of the air pipe between the perforated pipe and the inlet to the perforated drum, so that for a portion of the treatment, the drum will be filled with a blanket of live steam to the exclusion of the hot air.-

An object is to deodorize the cleaned particles and fabrics more effectively in a short period of time than by old processes and former apparatus.

An object of this invention is to make cheap and simple provision whereby well known apparatuses that are now on the market can'be provided with a steam con- But I do not limit myself to any particular point or part of the apparatuses to which I ma apply my steam connection- Ot er objects, advantages and features of invention may appear from the accompanying drawings, the subjoined detailed description and appended claims.

The accompanyin drawings illustrate the invention as applie in a conventional a paratus for dryin the cleaned materi s.

Figure 1 is a pfim of the improved apparatus, parts being broken away to expose construction.

Fig. 2 is an enlarged axial section of the steam pipe shown in Fig. 1.

,Fig. 3 is a transverse section on line indicated at m Fig. 1.

Fig. 4 is a VICW of the combined steam radiator and injector detached.

In the form of apparatus shown a drum 1 having-perforations 2, and a hinged door 3 is mounted inside a housing,.enclosing the drum and formed of a closed section 4 and a door 5 and a closed rear section 6, there being an air inlet 7 communicating with the drum 1 at the to and an outlet 8 at the bottom of the rum, and an air heating conduit 9 is arranged at the rear side of the housing and is provided with descending and ascending steam .coils 10 and 11 connected by the bottom limb12 and supplied with steam from the valved pipe 13 through a valve 14 opening from a live steam pipe 15, which is connected with a ing, and the exhaust steam finds its escape through the pipe 17 at the 1: p of said coils.

The heating conduit 9 extends upward and over the air inlet 7 to the drum, and

- known and my improvement consists in applying to the air conduit a steam injecting pipe 22, which is shown as being provided along one side with steam outlets 23, from which the steam is blown across the air passage in .the conduit 19, By this means steam is mingled with the air which is a1- 4 lowed to pass through the drum at certain condensed steam is fully a third limb with the stuffing box 25.

periods of my newly discovered process.

In order to apply the invention to former constructions in a simple and expeditious manner, I provide the steam supply plpe with a cross pipe joint 24, one limb 0 which is screwed onto the steamsupply pipe 15, another is supplied with the valve 14, nnld e fourth limb of the pipe joint 24 is supplied with a nip le 26 onto which is fitted the elbow valve 2 that supplies steam from the pipe 15 to the injecting pipe'22 between the heating coil and the inlet 7 to the drum.

The fan and the drum are connected by the spur and pinion ears 28 and 29 from power, not shown. 11 practical use, before the articles to be deodorized are placed in the drum 1, the valve 14 is opened long enough to assure perfect circulation of steam in the coils, while the valve 27 is closed. When such circulation is effected, the valve 14 is closed and the valve 27 is opened in order to blow out whatever steam ma have been condensed in the pipe 22 an within the drum 1 and the ousing therefor. As soon as the ejection of such assured, the valve 27 is closed and power is applied for a few moments in order to revolve the drum and thus to evaporate therefrom whatever moisture may have accumulated thereon or in- .side thereof. The door 3 of the drum is sure a blanket of steam within the apparatus, and the power for revolving the drum is turned on. The result is that after treatment of this kind for twenty or thirty minutes the remnants or. residue from the] cleaning substances have all been bodily driven out from the materials. Thereupon arments the valve 27 is again closed and only a blast of air from the fan 20, which air is heated by the coils 10, 11 and 16, is introduced in the apparatus for a period of twenty or thirty minutes, more or less, during which time the drum is rotated with the result that when the door 5 is opened, there is-no remnant of volatile cleansing liquid to become inflamed upon openin the drum; and the process is made perfect y safe.

The materials, after the treatment thus disclosed, are thenremoved and'are found to have a superior softness to the touch and to beperfeetly free fromany odor of the cleansing liqu1ds.

It is thus seen that allthat is necessary to supply either a new or an old time drying apparatus of the character shown, with means for the purpose set forth, is to provide the steam coil in theconduit 9 with the steam projecting pipe 22 provided along one side with steam outlets from which the steam will be blown across the air passage 7 in the conduit and to provide a valve connection between said pipe .22 and the live steam supply pipe 15. Said valved steam pipe 22 1s rought into and out of action inependently of the action of the heating coil and the heating coil is brought into and out of action independently of the perforated valved steam pipe 22. The hot air pipe 9 is arranged at its lower portion to extend underneat the bulging periphery of the cylindrical housing 4 and is wider at such portion as is clearly seen in Fig. 3 and is on a level with the axis of the drum contained in said housing; and the steam connection therein is formed of two coils 10 and 11 arranged front and back; the front coil 10 being composed of seven turns and the back 0011 extending above the level of the front coil for about the same number of turns. The rear wall of the air pipe is vertical and parallel to the front wall thereof so that the air pipe is narrow at the place w1l 1e(11'e the perforated steampipe 22 is ap- By this construction and arrangement, when the elbow valve 27 is open, the passage throu h the pipe9 is flooded with steam and t e flow of air therethrough from around the coils below is practically susended so that the contents of the drum are or the meantime treated with hot live steam without atmospheric air, and I term such 22 and the blast of hot air is again passed through the drum the hot steam in said pores will be carried off together with the odiferous substances.

I. claim: 1. The improvement and deodorizing textile fabrics or fibers drive the steam and odiferous substances from the drum and fabrics.

2. In a deodorizing apparatus of the character set forth the combination with the heated air conduit, the heating coil therein, the live steam pipe for said 0011, and a valve for controlling the flow of steam from the live steam pipe to the heating coil; of a in the art of drying p pe pipe arranged in the conduit above the main portion of said heating coil and provided with openings arranged to discharge steam across said conduit, and a valve connection between said steam pipe and the live steam 3. In a drying apparatus the combination with the revolving drum, the housing for said drum, and exhaust means; of an air supply opening through said housing into sai rum and having a contracted por tion; means for heating air in the air pipe below said contracted ort-ion, and controllable means for injectm live steam across the contracted portion or the purpose'ot' excluding air from the drum for a period of time and for temporarily supplying the drum with hot steam to form a blanket of steam for the contents of the drum.

In testimony whereof, I have hereunto set my hand at Los Angeles, California, this 22nd day of April, 1919.
