DYEmG MACHINE. I

Application led October Our invention relates to certain improvements in the dyeing maching for which application was filed by us on the 9th v,day of July, l1925, Serial No. 42,520. n i The object of the present invention 1s to improve the means of driving the paddles, so as to more thoroughly circulate the dye liquor, and to provide means for supplying the vats with dye liquor independently of the means for supplying water thereto. In the accompanying drawings: Fig. lis a plan view of our improved 'dyeing machine; s

Fig. 2 is a longitudinal sectional v1ew on the line 2-2,'Fig. 4;

Fig. 3 is an end view; and Fig. 4 is a transverse sectional view on the line -4-4, Fig. 1.

The vat 1 is elongated and has a curved bottom 2. Partitions 3 divide the vat into a series of compartments. The artitions are perforated vto allow the dye iquor to circulate through all of the compartments,

but the materialto be dyed is confined in its particular compartment.

In the bottom of the vat are perforated sections 4, under which are perforated steam pipes 5. In the present instance two pipes are shown, one extending from one end of the vat, and the other extending from the opposite end thereof. The steam heats the dye liquor in the vat.

The coloring matter is introduced into the vat by means of small pipes 6, which extend diagonally from each of the vats to a partition. At this point each two branches 7 one kdischar 'ng into one compartment, and the other d1scharging into an adjoining compartment, as shown in o Fig. 2. By this construction the coloring matter is introduced into the vat in small quantities at different points. At the outer end of each pipe is a valve 8, and above the valve is a funnel 9.

On each end of the vat is a bearing 10, and on the central partition `is a bearing 11. A longitudinal shaft 12 is mounted in the bearings. rI he shaft inthis instance does not rotate.

On the shaft 12 are fourpaddle-wheels 13, one for each compartment of the vat. Each wheel has solid side members 14 and paddles 15 attached thereto in any suitable manner. The

paddlesl may e modified without departing from the main features of the invention.

pipe has articular construction of the 2, 1925. Serial No. 60,085.

Mounted on a bracket 16 at one end of the vat is a reversing electric motor 17,. which drives a longitudinal shaft 18 at the side of thevat through gearing 19, shown by dotted lines in Fig. 3. The gearing is located in an enclosing casing 20.

The shaft 18 has its bearing in brackets 21 secured to the vat, vas shown in Fig. 1. Onv the shaft are bevel gears 22, which mesh with bevel gears 23 on transverse shafts 24 mounted in a bearing 25 .on certain partitions of the vat. Each shaft 24 drives two paddle-wheels through a bevel gear 26 on the shaft, and bevel gear wheels 27 on the paddle-wheels, so'v that the paddle-wheels rotate upon the fixedshaft 12.'

By the above construction, one paddlewheel of each pair rotates in one direction, while the other paddle-wheel rotates in the opposite direction, and when the motor reverses, `the direction of movement of allA paddle-Wheels is reversed. This causes tle` dye liquor in each compartment of the vat to circulate in a direction opposite to that in an adjoining compartment and through the perforated. partitions, insuring even dyeing.

The machine is especially adapted for dyeing stockings, and other knit or woven fabrics, and wool and fur felts.

In ordinary practice, when stockings are to be dyed, they are placed in bags-or are otherwise arranged in batches, and each compartment contains a certain number of bags or batches.

lVe claim:

1. The combination in a dyeing machine, of a vat a series of transverse partitions in the vat formingcompartments; a series of paddle-wheels,- one paddle wheel for each compartment, said paddle-wheels being arranged in pairs; and means for driving the wheels of ,each pair in opposite directions.

2. The combination in a dyeing machine, of 'a vat; a perforated transverse partition inthe vat forming compartments' a paddlewheel in each compartment; a 7bevel gear wheel on each paddle-wheel; a transverse shaft having a bevel gear wheel. meshing with the gear-wheels on the paddle-wheels@ and means for driving the transverse Shaft to cause lhe paddle-wheels to rotate in opposite directions.

3. The combination in a dyeing machine, of a vat; a series of perforated transverse partitions in the vat; a longitudinal shaft mounted on the vat; two pairs of paddle- Wheels mounted on the shaft, the paddle- Wheels being located in the compartments of the vat; a longitudinal shaft at the side of the vat; means for driving the shaft; and transverse shafts geared to the longitudinal shaft and to each pair of paddle- Wheels.

4. The combination in a dyeing machine, of a vat having a series of perforated transverse partitions therein; steam pipes in the bottom of the vat; a small pipe for admitting coloring matter to the vat, said pipes having branches opening into the compartments; a longitudinal shaft on the vat; a paddle-Wheel in each compartment and mounted on the shaft; a longitudinal driving shaft at the side of the vat; bevel gears thereon; transverse shafts having bevel gears at one end meshing with the gears on the driving shaft and having bevel gears at their opposite ends; and a bevel gear on each paddle-wheel meshing with the gears on the transverse shaft.
