This invention refers to dyeing, washing and like apparatus for textile goods, including felt hat bodies, but relates chiefly to dyeing apparatus of the type in which the dye liquor is-caused to circulate throughthe goods first in one direction and then in another direction, and in which the dye liquor enters and leaves the dyeing chamber at constantly varying points.

The object of the present invention is an improved construction of such type of apparatus andan improved method of circulating the dye (or wash) liquor, whereby more thorough, even and rapid dyeing (or washing) can be effected. According to the invention, a stationary vat is employed having a perforated floor part. Below said floor part is an enclosed chamber forming part of or additional to the vat, and within such chamber are liquor circulating devices whereby the liquor in said chamber and vat is caused to flow upwards and through the perforated floor at one side'of the vat, then horizontally through the vat to the other side, and then downwards through the perforated floor back into the said chamber, the circulating devices being preferably capable of rotary or angular movement so that the dye liquor shall flow in constantly changing directions with respect to the floor of the vat, the liquor flowing in a directly opposite direction after a half rotation of the said devices. 30 In addition to the said circulating devices, there may be one or more pumps below the said perforated fioonwhich will operate periodically to produce sharp upward impulses on the liquor, r in addition to the said'norm'al'fiow, thereby add ing to the efiiciency of the apparatus. In the accompanying drawings: Fig. 1 illustrates a sectional elevation of one example of the improved apparatus. Fig. 2 illustrates an enlarged sectional elevation, and I Fig. 3 alike plan of a part of the liquor circulating devices appearing in Fig. 1, but as shown separate from the vat.

Fig. 4 is a sectional elevation hereinafter described.

In the example shown in Figs. 1-3, the improved apparatus comprises the stationary, opentopped vat or container at provided with a per- 50 forated fioor part b, the perforations preferably extending over the whole area of the floor part. Below the floor part b, the vat is contracted in diameter to form a frusto-conical chamber 0, the whole vat being mounted on pillars or standards 4 of a modification v to the fast pulley k whereupon the propeller m d rising from a base e. Connected to the lower horizontal face of the part c of the vat, and. also connected to a frame-ion the base e are concentric elbow pipes g, h, the larger pipe It being closed at one end by a plate 72. provided witha central gland M, and the smaller pipe having its 5 end short of such plate so as to leave afree passage from one pipe to the other. 7

Carried in bearings'i mounted on the frame f is a horizontal shaft y carrying fast and loose pulleys k k for the drive (not shown), and carrying stepped pulleys Z, such shaft also extending through the gland 71 into the pipes g, h and carrying at its inner enda propeller m which lies within and closely fits the inner pipe 9, or which could be arrangedin the pipe h.

A further horizontal shaft n mounted alongside the frame f carries stepped pulleys 0 complemental to the pulleys Z, and driven therefrom by a belt Z and also carries a worm pf which meshes with a. worm wheel q'on' a verticalshaft r; Such vertical shaft 1' is mounted in bearings f at the end of the frame'f, a thrust bearing 1' being provided to take the weight, and the shaft extends upwards through a gland h on the elbow pipe h, into the frusto-conical chamber 0. At v the upper end of the shaft 1" there is fitted a cowl or spout member s havinga h'ousing formation to fit over and enclosethe end-of the inner elbow pipe 9, and a further housing formation to fit over a part of the annular space between the pipes g and h. The members has a notch or spout a substantially of V shape in elevation, below which notch or spout isformed a box-like housing s which lies over the said annular space. The member s also has fins or vanes t extending to the wall of the chamber 0.

In operation the 'materials or articles to be dyed or washed are placed in the' vat a, above the perforated floor I), and the machine'is filled with the dyeing or washingliquor up to the desired level, the liquor filling the pipes g and h, the conical chamber 0 and so much of the vat a as is necessary to cover the materials or articles.

The driving belt (not shown) is then moved is rotated and causes a flow of liquid up the central pipe g, the liquor being forced through the Vnotch orspout s and through the perforated floor b,'and after flowing through the goods being treated, returning via thefioor b into the outer elbow pipe h and back to the propeller, and soon. At the same time, the shaft 2" and the cowl or housing s are rotated so. that the positions of the points at which the liquor passes upwards quickly.

are isolated from each other, that is to say, the

box-like housing s below the V notch 8 serves to separate the outgoing stream from the suction in the outer elbow pipe h. At the same time there is a relatively large area of the elbow it open to the liquor, which prevents undue obstruction to the circulation.

The cowl s and fins t may extend up to the floor b or may stop short of the same as shown.

In another example of the invention, and as illustrated in Fig. 4, each pipe g, h, at its upper end carries a curved elbow-like spout, the spout of the inner pipe extending in a'direction opposite to and passing through the wall of the spout of. the outer pipe. The two spouts are more or less integral, and are adapted to rotate as one upon the top end of the shaft r over the pipes g, h. Extending laterally from the combined spouts are the plates or fins not shown in Fig. 4, but identical in shape with those shown in Figs. 1-3, which extend across the chamber below the dye vat, and at their edges lie near to and follow the contour of the innerface of chamber 0.

In any of the examples, the-direction of rota-.

tion of the screw propeller may be made reversible at intervals so asto propel the liquor first in one direction and. then in' the opposite direction. g i

In some cases a heating coil may be inserted in the inner elbow pipe to heat the liquor.

When the impulse pumps are used belowthe perforatedfloor (or cage) they will usually each consist of an open-endedcylinder, with the open end uppermost, anda piston or plunger operated to move down slowly. and ;move upwards In'one example the piston is spring actuated, the spring being slowly compressed and then quicklyreleasedg 1 .In place ofa screw propeller, a rotary or reciprocating pump may beprovided.

The improved apparatus'ischiefly for use in dyeing felt or fur hat bodies, but it may also be used in the washing or other liquid treatment of other articles or goods. It may for instance be usedin laundering.
