SPECIFICATION forming part of Letters lPatel-1t No. 729,333, dated May 26, 1903. Application led Julyy 30, 1902. Serial No. 117,646. l (No model.)

To all whom t may concern:

Be it known that we, ABRAHAM .IIAAS and EDGAR BARUCH, citizens of the United States,

and residents of San Francisco, in the county of San Francisco and State of California, have invented a new and Improved RawLIVool- \Vashing Apparatus, of which the following is a full, clear, and exact description;

The invention relates to apparatusl for washing raw sheeps wool and similar ibers,

and its object is to provide a new and im!y proved raw-wool-washing apparatus which is simple and durable in construction, very effective in operation, easily manipulated, and arranged to permit its use in local wool-grow-- ing centers, to allow of washing' or cleansing raw sheeps wool andl other textile iibers With- A practical embodiment of the invention isv represented in the accompanying drawings,

forming a part of this specification, in whiclr similar characters of reference indicate corresponding parts in both views.

Figure l is a front elevation of the improve-, ment, parts being shown'in section; and Fig.

2 is a side elevation of the same. Y

The improved apparatus is'inounte'd-on a suitably-constructed frame A, which supports an extractor B, preferably in the form of a cylinder closed atthe lower end and provided at its upper end with a removable cover B for introducing or removinga wire cage C, containing the raw sheeps woollor like liber Dtobetreated, i; .I The upper end of the extractor B is connected by a pipe F,`having a valve E', with the lower end of a reservoir F,for containing benzin or a similar hydrocarbon cleansing compound for dissolving the fats andV greases contained in the raw sheeps wool yheld inthe cage C,"inserted in the extractor B. The bottom of the latter is connected by a pipe G, having a valve G, with a caldron I-I, in the shape of a closed vessel, containing in its bottom a steam heating-coil I, having one outer end I provided with a valve I2 and connected vwitha steam-supply pipe J, leading from a boiler yor similar source of steam-supply. A branch steam-pipe K leads from the supplypipe .I into the lower end of the extractor B, land the said steam branch pipe K is provided with avalve K', normally in a closed position.

From the top of the caldron H leads a pipe L, connected at its upper end with a condenser Nin the shape of a plurality of coils extending within a water-tank O, through which passes water or other cooling medium supplied by a pipe O and carried off by a discharge-pipe O2. The lower end of the condenser N terminates in a pipe N', connected with the upper end of the reservoir F,

whichlatter is provided at its bottom with a gage F' for determining the presence of water of condensation, as hereinafter more fully described, and ythe said reservoir F is also provided with a gage-glass F2 for indicating itheplevel of the liquid contained in the reser- .with the pipe L, leading to the condenser N.

The caldron H is provided with a chargingfunnel Q, having a valve Q.

rlfhe operation is as follows: The raw' sheeps wool or similar ber is placed into the cage C, and then the latter, with the wool, is

introduced into the extractor B, after which lthe cover B/ thereof is closed and the valve 'E/ ris then opened to allow the benzin to iiow by its own gravity from the overhead reserv-voir F through the pipe E into the extractor B in contact with the wool, so as to dissolve fats and greases adhering to the wool fibers and at the same time loosen dirt and other impurities. The liquid benzin percolates through the wool and finally passes through vthe pipe G into the caldron II, carrying with it the dissolved fats and greases as well as other impurities.

In the caldron I-I the benzin is separated from the fats, greases, dirt, and. other extraneous matter by heat emanating from the coil I, which heat evaporates the benzin, and the vapors now pass from the caldron I-I up through the pipe L into the condenser N, in


which the benzin vapors are converted back into liquid form, passing by the pipe N' into the reservoir F to be reused in the extractor B, in the manner above described. This operation is continued until the greases and fats of the wool have been completely dissolved and removed from the extractor.

As shown in the drawings, the ealdron Il is located below the extractor B, so that the liquid benzin and the substances dissolved therein flow by gravity from the extractor into the caldron whenever the valve G is opened. If desired, the valve G may be closed and the liquid benzin containing the dissolved fats and greases may be siphoned from the extractor ll, and ii'or this purpose a self-starting siphon G2 is provided, connected at its short leg with the pipe G and at its long leg with the ealdron ll, the said long leg having a valve G, which may bc closed whenever desired.

The pipe G is provided with a test-cock l to indicate the condition of the benzin and the substances dissolved thereinthat is, when the benzin shows comparatively clear at the test-cock, then the fais and greases have been removed from the wool and carried to the caldron ll. 'hen this has been done, then the valves l2, G, G, and E are closed and the valve K in the pipe K and the valve P in the pipe P are now opened, so that steam passes from the supply-pipe .l through the pipe K into the lower end of the extractor B and through the wool contained therein, so that any benzin adhering to the wool, cage C, or wall of the extractor l5 is vaporized and carried with the steam by way of the pipes P and L to the condenser N to be condensed therein. The water of condensation flowing by the pipe N into the reservoir F readily separates from the benzin, and this water can now be drawn o through the gage-cock F, which also indicates when the water has been completely Withdrawn from the reservoir and the latter only contains benzin. Then the benzin has been. expelled from the extractor B, as described, then the valves K and P are closed and the cover B is then opened and the cage C, with the cleansed wool, is removed, and the cage is refilled with raw clipped wool and again inserted in the extractor B. The above-described operation is then repeated-that is, the valves E', G, and I2 are opened to subject the wool in the extractor to the action of the liquid benzin to allow the benzin and the fats and greases dissolved by it to pass to the caldron ll, in which the benzin is vapor-ized and separated from the fats and greases and other extraneous matter, as above explained.

The bottom of the caldron H is provided with a discharge-faucet H for discharging the fats, oils, and other impurities from the caldron II whenever it is desired to do so.

From the foregoing it will be seen that the benzin employed is used over and over again, so as to permit of cleansing the wool at a comparatively low cost.

Having thus described our invention, we claim as new and desire to secure by Letters Patentl. In an apparatus of the class described, the combination of a main frame, an extraetor mounted centrally thereof, a cage for containin the material to be treated and adapted to be inserted in said extractor, a reservoir situated above said extractor and connected therewith, said reservoir supplying benzin to the extractor, a caldron below said extractor, means for siphoning the benzin from the extractor to the caldron, a heating-coil in said caldron, a condenser above the reservoir communicating with the caldron and said reservoir, and means for introducing a charge of steam upward through the material in the extractor, as set forth.

2. In an apparatus of the class described, the combination of a main frame, an extractor provided With a cage for the material, mounted centrally of said frame, a reservoir for a liquid cleansing compound mounted above and connected with said extractor, a caldron provided with a heating-coil mounted beneath the extractor, a pipe leading from the bottom of said extractor, a self-starting siphon having a short leg connected with said pipe and its long leg with the caldron, a valve for said siphon, a reservoir mounted above the extractor, a condenser above the reservoir, said condenser communicating with the caldron ,the vapor passing from the caldron being liqueiied in the condenser, means for drawing off the water from the condenser, and means for conveying the liquid cleansing compound from the condenser to the reservoir, substantially as set forth.

In testimony whereof we have signed our names to this specification in the presence of two subscribing witnesses.
