(Cl. 68-435) ABSTRACT OF THE DISCLOSURE A dyeing apparatus for textile goods wherein a foraminated basket, carrying motor driven paddles, is normally positioned in an open top vat and is mounted to be pivotally moved upwardly for discharging the dyed goods therefrom by the use of fluid pressure operable means adapted to be moved from a normal retracted position to an extended position to effect the dumping of the goods.

The present invention pertains to an improved paddle dyeing apparatus for use in dyeing textile goods, and more particularly, to a paddle dyeing apparatus wherein the handling of the textile goods during loading and unloading is greatly facilitated, thus increasing the overall efficiency of the dyeing operation.

Accordingly, it is a primary object of the present invention to provide an improved paddle dyeing apparatus for textile goods, which is adapted to be readily loaded with undyed textile goods from one side and which the unloading of goods after dyeing from the opposite side is facilitated.

A more specific object of the present invention is to provide an improved paddle dyeing apparatus for textile goods in which the unloading of goods after dyeing is facilitated by the provision of means for pushing a'basket containing dyed goods upwardly to an extended or unloading position.

A further specific object of the present invention is to provide an improved paddle dyeing apparatus for textile goods in which means are provided for pushing a basket containing dyed goods upwardly from a dyeing position for unloading, with provision for stopping the basket in an intermediate position for purposes of draining dye liquor from the dyed goods, and wherein snagging of or damage to textile goods upon their movement in the basket is substantially reduced.

FIGURE 9 is an enlarged section view through a foramen and the wall of the basket of the apparatus of FIGURE 1.

Referring now more particularly to the drawings, a paddle dyeing apparatus, indicated generally at 10, is shown, which is adapted for the dyeing of textile goods.

The dyeing apparatus of the present invention includes a vat 11, which is adapted to contain a dye liquor or other liquid media with which textile goods are to be treated, and includes a front wall 12 and a back wall 13.

The vat 11 has a generally half cylindrical configuration, and is supported by a base including side standards 14, 15 and structural open box members 16, 17, the function of which will be made clear hereinafter. Dye liquor may be introduced into the vat through a dye pipeline 20, from any suitable source (not shown), and drain pipelines 21 and a drain valve 22 are provided in order to drain dye liquor and other textile material treatment media from the vat 11 upon the completion of treatment. As water will from time to time be used to clean the vat 11 or to treat goods in the dyeing apparatus, a water pipeline 23 is provided and, as it will upon occasion be necessary to heat the treatment media contained Within the vat 11, a steam pipeline 24 is provided. The water pipeline 23 and steam pipeline 24 are connected to suitable sources of these fluids (not shown).

A foraminated basket, indicated generally at 25, is provided for containing the goods to be treated in the dyeing apparatus. The basket 25 is of a shape substantially conforming to the interior configuration of the vat 11, and has a front wall 26 and a back wall 27. The basket 25 is pivotally connected to the vat 11, at the upper extremity of the front walls 12, 26 of the vat and basket. Preferably, this pivotal connection is obtained by providing hearing or journal plates 30, 31, positioned on opposite sides of the vat 11 and secured to the standards 14, 15. A pintle rod 32 is secured to the upper extremity of the front wall 26 of the basket 25, and carried within the journal plates 30, 31, to define an axis for pivotal movement of the basket over a range of positions from a normal position within the vat 11 to an extended position outside and above the vat 11 (FIGURE 1). The basket 25 is foraminated, preferably throughout all wall surfaces, at least to a level equal to the height of dye liquor within the vat 11 at the time dyeing is to take place. Thus, with the basket 25 in the normal, or lowered position, the dye liquor contained Within the vat 11 freely flows into the basket 25 to come into contact with textile goods contained therein.

In order to agitate textile goods contained within the basket 25, and thereby assure proper dyeing or fiuid treatment of the goods, the dyeing apparatus of the present invention is provided with a plurality of paddles 33. The paddles extend along the longitudinal axis of and are mounted around a shaft 34, for rotation therewith, and the shaft is rotatably mounted on the upper portion of the basket 25 in suitable bearings 35, 36 to extend parallel to the front wall 26 of the basket 25. Suitable power means, such as an electric motor 37, is provided for driving the shaft 34 in rotation, through a suitable reduction gear transmission 40, to thereby rotate the paddles 33 and agitate goods during dyeing. Preferably, the motor 37 is mounted :on the basket 25, for movement therewith, to substantially simplify the mechanical problems of permitting such movement of the basket 25. In order to obtain satisfactory dyeing of certain types of goods the agitation of the goods by the paddles 33 should vary from time to time. According, the apparatus 10 includes an electrical control device 38 (FIGURE 2) such as a timing mechanism, effective to reverse the direction of rotation of the motor 37, shaft 34 and paddles 33 at predetermined intervals, as indicated by arrows in FIGURES 7 and 8.

Inasmuch as the dye liquors to be used in dyeing textile goods are frequently of a corrosive nature, and as generally known, the ambient atmosphere Within a dye house includes fumes of such corrosive dye liquors, precautions are taken to protect the apparatus from corrosive effects to the greatest degree possible. More particularly,

splash guards 41 are provided around the upper periphery of the basket 25, and a guard 42 encloses the power means for driving the shaft 34 and paddles 33 in rotation. Preferably, such guards 41, 42 and all possible portions of the dyeing apparatus 10 are formed of stainless steel.

In order to move the basket 25 to selected positions, and thereby facilitate the unloading of dyed goods from the front side of the dyeing apparatus, this invention contemplates the inclusion of fluid pressure operable means operatively connected to the basket 25 for pushing the same upwardly to desired positions ranging from the nor-. mal position for dyeing operations to an extended position in which goods are removed from the basket 25. More particularly, the dyeing apparatus of the present invention includes two extensible hydraulic cylinder devices 50, 51, disposed at opposite sides of the dyeing apparatus 10. The cylinder devices 50, 51 may be substantially conventional devices, constructed with a cylinder, a piston moving within the cylinder, and a connecting or piston rod extensible relative to the cylinder upon application of fluid pressure to the piston within the cylinder. The upper end of each cylinder device 50,51 is pivotally connected to the basket 25, rearwardly of the pivotal connection of the basket 25 to the vat 11 (FIG- URES 1, 3 and 5). The lower end of the each cylinder device 50, 51 is pivotally connected to a side standard of the dyeing apparatus, by means of a trunnion pin extending through the standard and associated box member (FIGURE 6). As the cylinder devices 50, 51 are thus connected to the apparatus 10, the connecting rods of the cylinder devices are in a retracted position and housed within the cylinder at the time that the basket 25 is in the normal position for dyeing operations. As it is at this timethat the greatest danger of splashing of dye liquor is present, and thus of corrosive damage to the cylinder devices, the cylinder devices 50, 51 are thus pro-. tected from damage by corrosion.

The fluid pressure operable means additionally includes a pump for supplying operating fluid under pressure and a control valve .system for controlling the application of fluid to the cylinder devices 50, 51 (FIG- URE 3). In order to protect these elements of the fluid operable means from corrosion damage, the pump P and an electric motor M driving the pump are preferably positioned outside the dye house area, and awayfrom the corrosive atmosphere of the dye house. Hydraulic pressure is supplied from the pump through hydraulic lines 53 to, control mechanism 54, and thence to the cylinder devices 50, 51.

In order that the fluid pressure operable means be operated only when required to move the basket 25, the control mechanism 54 provides a particular interconnection for the elements of the fluid pressure operable means. More particularly, the control mechanism 54 incorporates a four-way or reversible valve, effective to apply fluid pressure developed by the pump P to the cylinder devices 50, 51 in such a manner as to cause the devices to push the basket 25 upwardly from the dyeing position to the unloading position, or to draw the basket 25 downwardly from the unloading position to the dyeing position. Upon movement of the valve into a position at which fluid pressure is to be applied to the cylinder devices 50, 51, an electrical switch S is closed to apply electrical current to the motor M and operate the pump P to deliver the required fluid pressure. When the valve mechanism is in an intermediate, or neutral, position so that fluid pressure is not applied to the cylinder devices 50, 51 the switch S is open, and the motor M is not energized to drive pump P. Therefore, the fluid pressure operable 4 means is operated only as required to move the basket 25. When it is desired to move the basket 25 between the dyeing and unloading positions, suitable hydraulic fluid is supplied to the cylinder devices 50, 51, to effect extension of the cylinder devices. The pivotal connections at the upper and lower end of the cylinder devices 50, 51 accommodate the changing relative positions between those devices and the side standards 14, 15, and basket 25 of the dyeing apparatus 10.

In operation, the basket 25 is lowered to the dyeing position, within the vat 11, and dye liquor is admitted into the vat to the desired level for a dyeing operation. Thereafter, textile goods to be dyed may be introduced-over the back walls 13, 27 of the vat 11 and basket 25, to be submerged in the dye liquor and agitated by the paddles 33, which are driven in alternate directions of rotation under the control of a timing device. Thereafter, when dyeing is completed, the hydraulic control device 54 is actuated to simultaneously start the pump supplying hydraulic fluid to the cylinder devices 50, 51 and apply pressurized hydraulic fluid to the pistons within those.

cylinder devices. The basket 25 is thereupon lifted to an intermediate position, in which the basket is above the dye liquor bath contained in the vat, so as to permit drainage of excess dye liquor from-the goods contained within the basket 25, but not to the extreme position. Upon the completion of drainage, hydraulic pressure is again applied to the cylinder devices 50, 51 to push the basket upwardly into the extended position and thereby dump the dyed goods into a truck or carrierpositioned at the forward side of the dyeing apparatus 10.

In order to further facilitatethe unloading of dyed goods from the apparatus 10 of the present invention, the present invention contemplates a particular manner of forming the foramen in the foraminated basket 25. More particularly, the edges of each foramen, as defined by the materials surrounding the opening, are embossed and rounded toward the inner side of the basket 25 walls (FIGURE 9). Such an embossed foramen presents no roughened or sharp edges on the inner surface of the walls of the basket 25, and thereby permits dyed goods forth a preferred embodiment of the invention and, al-

though specific terms are employed, they are used in a generic and descriptive sense only and not for purposes of limitation, the scope of the invention being defined in the claims.
