DYEIN G APPARATUS.

Specification of Letters Patent.

Patented Sept. 26, 1911.

To all whom it may concern:

Be it known that I, VILLIAM R. SMITH, of Buffalo, in the county of Erie and State of New York, have invented certain new and useful Improvements in Dyeing Apparatus, of which the following is a specification.

This invention has for its object to provide a simple and effective apparatus for dyeing fibrous materials of various kinds,

and particularly fibrous material in the form of yarns or threads, contained in a receptacle which is immersed in a body of dye liquor.

The invention is embodied in an apparatus in which the inclosed fibrous material to be dyed is subjected to contact withthe dye liquor, not only by being submerged therein, but also by being rotated while submerged in the liquor, the rotation of the body of fibrous material to be dyed being caused by movement of the liquor in a tank or reservoir.

The invention consists in the improvements which I will now proceed to describe and claim.

Of the accompanying drawings z-Figure 1 represents a top plan view of a dyeing` apparatus embodying my invention; and Fig. 2 represents a section on line 2-2 of Fig. l.

Similar reference characters indicate the same or similar parts in all the figures.

In the drawings, 12 represents a horizontal endless tank composed of a bottom 12, an outer curb 12b, and an inner curb 12C, the said curbs being endless and preferably in the form of flattened ellipses so that they form an endless horizontal passage of substantially elliptical form in which the body of dye liquor may be confined and circulated. Means are provided for circulating the dye liquor, said means, as here shown, comprising two paddle wheels 13, the shafts 14: of which extend across the relatively straight portions of the tank, and are provided with bevel gears 15 meshing with a bevel gear 16 on a driving shaft 17.

The described mechanism is adapted to rotate the paddle wheels simultaneously in opposite directions and thus cause a continuous circulation of dye -liquor in the tank, as indicated by arrows in Fig. 1.

18,18 represent cylindrical rot-ary baskets adapted to contain the material to be dyed, and made of open Work material such as Woven wire or perforated sheet metal, so

that the liquor may pass freely through the basket-s and the material contained therein. Each basket is adapted to rotate on a vertical axis 19 supported at its lower end by the bottom of the tank and engaged at its upper end with a suitable bearing on a cross bar 20, which may be removably connected with the tank to permit the removal of the basket. Each basket is preferably of annular form, the inner side of its storage space being formed by a perforated wall 18 which is concentric with the outer wall. The basket may be removably mounted on the axis 19, or it may be suitably engaged therewith and filled and emptied without removal from the tank, a suitable removable cover being provided.

The baskets are entirely submerged in the body of dye liquor, and are rotatable by the movement of the liquor in the tank so that all sides of each basket are presented to the advancing stream of liquor. In the construction here shown the rotation of the baskets is due primarily to the fact that the axis of each basket is located nearer the inner curb 12c than the outer curb 12b so that there is a relatively wide space between the outer side of the basket and the outer curb. The moving body of liquor therefore exerts a greater pressure on the outer side of the basket than on the inner side, and thus causes the rotation of the basket.

The baskets are preferably located in the abruptly curved portions of the tank, as shown by Fig. l, so that the liquor flowing along the relatively straight portions of the tank is deflected by the curved portions of the outer curb. against the outer sides of the basket, thus increasing the speed of rotation of the basket beyond that which it would have if the basket were located in a relatively straight portion of the tank.

When the described apparatus is used for dyeing wool, the material may be in the form of sliver disposed in tops or cheeses and placed in the baskets. It is obvious, however, that fibrous material of any kind and in any form may be dyed by the apparatus.

It is obvious that the tank may be provided with one or more baskets, and that when the tank is of elliptical form as shown, each of the abruptly curved portions may have one or more baskets.

Y Copies of this patent may be obtained for The location of the axis of the basket nearer one side of the tank than the opposite side Would be suficient to cause the rotation of the basket by the moving liquid it' the basket were located in a relatively straight portion of the tank. YThe deflection of the moving liquid by the outer side of the abruptly curved portion of an elliptical tank, Will cause the rotation of a basket located in said portion, Whether the axis of the basket be located nearer one side than the other or equidistant from said sides.

l. An apparatus of the character stated comprising an endless horizontal tank, means for moving liquid horizontally therein, and a basket mounted to rotate on a substantially vertical axis in the tank and rotatable by the movement of the liquid therein. y

2. An apparatus of the character stated comprising an endless horizontal tank, means for moving liquid horizontally therein, and a basket mounted to rotate on a substantially vertical axis in the tank, said axis being nearer one side of the tank than the opposite side, whereby liquid moving in the tank is caused to rotate the basket.

character stated substantially vertical axis in the tank, said tank having a substantially straight portion and an abruptly curved portion, and the basket being located in said curved portion, whereby liquid moving in the tank is deflected against the outer side of the basket and caused to rotate the latter. y

4. An apparatus of the character staten comprising an endless horizontal tank, means for moving liquid horizontally therein, and a basket mounted to rotate on a substantially vertical axis in the tank, said axis being nearer one side of the tank than the opposite side, and the tank being formed with a substantially straight portion, and

with an abruptly curved the basket is located.

In testimony whereof I have affixed my signature, in presence of tivo Witnesses.
