SPECIFICATION forming part 0f Letters Patent No. 432,573, dated July 22, 1890. Application -filed March 13, 1890. Serial No. 343,740. (No model.)

To all whom, it may concern: Beit known that we, ISAAC SMITH and .Io-A sEPH SMITH, citizens of Great Britain, resid` ing at Halifax, in the county of York, Eng# land, have invented certain new and useful Improvements in Apparatus for IVashing or Scourin g Tool and other Fibrous Substances, also for Mordanting, Dyeing, and Extracting Animal from Vegetable Fiber; and we do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

t In constructing a machine according to our invention we employ any suitable form of s vessel provided with a perforated false bottom. This perforated false bottoni is elevated at Y the outlet end of the machine, the height of which practically determines the depth of liq-v uor contained in thesaid vessel. c The scouring, dyeing, or other liquor is introduced at the feeding end of the machinein a continuous stream, escaping or running over the bridge at the outlet end of the machine. The fiber to be treated is introduced into the vessel and floats on the top of the liquor; but a seriesof revolving rollers or perforated cylinders are employed for the purpose of immersingor dipping the fiber into the liquor as it is being carried alongby the stream. Finally the fiber floats to the bridge, where it enters between one or m ore pairs of squeezing-rollers 5 but between the squeezing-rollers and the bridge there may be a revolving perforated cylinder or roller and an endless apron. The sediment from the fiber passes through the perforated false bottom, so as to keep the liquor pure, but the overflow-liquor falls into a vessel placed underneath the scouring-vessel,

from whence it is removed by a pump'and understood, we will now make reference to ,the accompanying sheets of drawings illusdanting, dyeing, and extracting animal from.

vegetable fiber. Fig. 2 is a longitudinal seei tion through amachine similar to Fig. l, with the vessel for delivering the liquor in ashower applied to it.

A represents a vessel provided with a false bottom B, preferably perforated at C. This false bottoni B is elevated at the outlet end of the machine, as shown at D, and the scouring or ot-her liquor which is being employed may be contained in the lower vessel E, from which it is pumped through the pipe F into the scouring or dyeing vessel A, or the liquor may be introduced into the said vessel from other sources. The quantity of liquor in the vessel A is determined by the height of the bridge D. It is therefore apparent that if a continuous stream of liquor is enteringinto the feeding end of the vessel A it will over- Ilow at D at the same rate as it is entering at the feeding end, and as the false bottom B at the feeding end of the machine is made at an angle, as the drawings indicate, the liquor is caused to flow quickly across the vessel A, for purposes hereinafter described.

The fiber to be treated is vfirst of all placed on the endless traveling apron II, from which it falls upon the liquor in the vessel A, the

flowing stream of such liquor carrying the fiber floating on its surface to the opposite end of the machine; but in order to prevent the liber traveling as quickly as the flowing stream revolving immersion-cylinders I are employed, driven by the endless chain or cord J, for the purpose of immersing or dipping the Heating liber inte the liquor, thereby retarding or holding the iberback; but meanwhile the flowing stream runs through and permeates the fiber, and, as the dippingicylinders are perforated, the scouring or dyeing liquor forces its way through the perforations, escaping out of the opposite side of the dippingcylinders, thereby removing the fiber which may be adhering to the periphery of the said perforated cylinders. Vhen the IOO iioatin g liber reaches the bridge D, it is Washed over by the liquor, which liquor escapes through another revolving perforated cylinder K, falling into the lower vessel E. The iiber afterward gets onto the endless traveling apron L, passes through the squeezingrollers M, from which it is removed by small revolving roller N onto the endless apron O, aftcrwhich it may fall into a suitable receptacle placed to receive it, or the said fiber may pass through a machine corresponding to that already described, for the purpose of beingsubjected to another like process. The sediment washed from the fiber will pass through the perforations C into the chamber P, and can be removed therefrom by removing the stopper Q. There is also aperforated dish R in the lower vessel to receive the impurities from the liquor falling therein.

In combination with the machine above described, and illustrated in Fig. 1,we may use an upper vessel S, (see Fig. 2,) having a perforated bottom, so that the liquor contained therein will escape through such perforations and fall in the form of a spray or shower upon the fiber Iioating on the top of the liquor in the vessel A. In this case the scouring or dyeing liquor falling into the lower vessel A is pumped back into the upper vessel S, instead of into the lower vessel, as illustrated and described with regard to Fig. l, and in order to increase the impetus of the flowing stream one or more pipes 'l may be connected to the under side of the upper vessel E, so that in addition to the shower of liquor such liquor may pass down the said pipe T, acceleratin g or increasing the speed of the iiowing liquor.

So far the invention has been described as applied to scouring, mordal'iting, and dyeing fibers; but we use a machine, as shown in Figs. l or f3, for the purpose of extracting animal from vegetable matter, the process or operation being the same as in the washing 0r dyeing,with this exception, that the liquor employed is a solution of bichloride of calciuln prepared by the admixture of hydrochloric acid or other suitable acids for the purpose of destroying vegetable matter contained in the ber.

We claim as our invention- 1. In apparatus for treating fibers, the combination, with a shallow vessel provided with a bridge at its rear end and with perfor-ations in its bottom and a chamber for sediment under the said perforations, of an inlet for liquor at the front end of the said vessel,whereby the fiber may be carried along by the liquor and iioated over the said bridge at its rear end, substantially as set forth.

2. In apparatus for treating fibers, the combination, with a shallow vessel provided with a bridge at its rear end,of an inlet for liquor at the front end of the said vessel, whereby the ber may be carried along by the liquor and Heated over the said bridge, and revoluble cylinders journaled above the said vessel for retarding the motion of the floating Iiber and pressing it below the surface of the liquor, substantially as set forth.

3. In apparatus for treating fibers, the combination, with a shallow vessel provided with a bridge at its rear end,of an inlet for liquor at the front end of the said vessel, whereby the fiber may be carried along by the liquor and floated over the said bridge, and a vessel provided with a perforated bottom and supported over the front end of the aforesaid vessel for causing a shower of liquor to descend upon the surface of the fiber, substantially as and for the purpose set forth.

In testimony whereof we affix our signa tures in presence of two witnesses.
