VAT FOR DYEING, &G.

- SPECIFICATION forming part of Letters Patent No. 780,402, dated January 17, 1905.

I Application filed September 9, 1904. Serial No. 223,890. l

To all whom, it may concern:

Be it known that I, JAMES Ai WILLARD, a citizen of the United States, residing at Chattanooga, in the county of Hamilton and State of Tennessee, have invented new and useful Improvements in Dyeing or Bleaching Vats, of which the following is a specification.

This invention relates to vats particularly adapted for dyeing and bleaching, and aims 1 o to construct a vat for such purpose which shall be simple in its construction, strong, durable, and efcient in itsuse, and comparatively inexpensive to manufacture.

With the foregoing and other objects in view the invention consists in the novel combination and arrangement'of parts hereinafter more specifically described, illustrated in the accompanying drawings, and particularly pointed out in the claims hereunto appended.

Ifn'describing the invention in detail reference is had to the accompanying drawings, wherein like characters of reference denote corresponding parts throughout 'the several Views, and in which- Fignre l is a sectional elevation of a vat constructed in accordance with this invention. Fig. 2 is a plan "view of the top or cover plate for the vat. Fig. 3 is a top plan view of the vat with the top plate removed. Fig. 4 is av longitudinal' sectional view of the top plate when used for bleaching purposes,.and Fig.

5 is aL longitudinal sectional view of the bot` tom plate when used for bleaching purposes. A vat constructed in accordance with this 3,5I invention for bleaching or dyeing purposesl dium, and said receptacle may be of any snitable contour and is provided in its bottom with an opening into which extends a dyeing or'bleaching medium supply pipe 2. The bottom of the receptacle 1 is also provided with an opening into which extends a steam-supply pipe 3, and upon the bottom of said receptacleA is arranged a perforated steam-pipe 4, whichv communicates with the steam-supply pipe 3. The function of the steam-pipes 3 and 4 is to supply'steam to the bottom of the vat, so as to heat the bleaching or dyeing medium when occasion requires. The receptacle l in the side thereof and at the top is formed with an outlet `5, said outlet 5 being always above the perforated top or cover plate to be hereinafter referred to.

Arranged above the mouth of the supplypipe 2 and within the receptacle l is a deflector 6, which is adapted to deflect the medium supplied by the pipe 2, so that saidv medium will properly pass through the mass of material being treated, which would not be the case if the detlector was dispensed with. Connected to orformed integral with the receptacle 1 in suitable relation with respect to the outlet 5 is a casing 7, forming an overflowchamber 8 and in which isarranged a filtering medium 9 in close proximity to'the outlet 5, said ltering medium 9 preferably being a plurality of wire screens. The function of the filtering medium 9 is to arrest the outiiow of any foreign bodies from the receptacle l, such bodies tending to clog the suction-pipe 10, which communicates with the chamber 8.- A The supplemental bottom, carrying the material to be treated, is supported within the receptacle l and consists of a plate corresponding in contour to said receptaclel and which is indicated by the'reference character 11 and suitably perforated throughout. Projecting from the bottomv of the plate l are a pair of annular supporting members 12, which are angular in cross-section, and said members l2 support the plate l1 a suitable distance above the bottom of the receptacle, forming thereby an auxiliary chamber for the reception of the dyeing or bleaching medium. The plate 12 is further provided with a plurality of eyes or other equivalent devices 13 to permit of attaching said supplemental bottom with a suitable hoisting device of any description, so that said supplemental bottom can be re- *moved from the machine after the material Ahas been treated, carrying the material therewith, and which will also permit of the transporting of said supplemental bottom with the material to any suitable point desired. Through the medium of the eyes 13 and the hoisting device the supplemental bottom can be replaced in position within the receptacle 1. The receptacle 1 is further provided with a removable top or closure and which consists of a plate 14, conforming in contour to the reeeptacle l and which is perforated throughout. Upon the upper face of the plate 14, at the edge thereof, a reinforcing brace member is secured, which extends entirely around the margin of said plate 14 and which is angular in cross-section. Secured to the upper face of the plate 14 is a series of segmentalshaped reinforcing members 16, which are also angular in cross-section, and, further, secured to the upper face of the plate 14 is a circular reinforcing member 17, which is also angular in cross-section and which surrounds a spider 18,eonnected by suitable holdfast devices to the center of the plate 14. The central portion of the spider is reinforced by the plate 19, attached to the spider and the plate 14. The closure is further provided with a plurality of eyes or other equivalent devices to permit of connecting therewith a hoisting device, so that said closure can be removed from within the receptacle 1. The closure also acts as a compression-plate for the material. Said closure is somewhat heavy and when placed upon the material and held down in a manner as hereinafter referred to the material carried by the supplemental bottom is compressed to substantially a solid mass. The means for retaining the closure in position consists of a plurality of lockingdogs 20, which are adapted to engage the reinforcing member 15 of the closure, and said dogs are so constructed and mounted that they can be swung into and out of the receptacle 1. The dogs 2O are each provided with a hollow sleeve 21 to permit of the mounting of said dogs 2O upon a plurality of vertically-extending slotted rods 22, which are secured at their lower ends to the heavy apertured lugs 23, connected with or formed integral with the outer face of the receptacle 1. The rods 22 are secured to said lugs 23 through the medium of the nuts 24. The locking-dogs 20 are retained in their locking position through the medium of the wedges 25, which extend through the slots of the rods 22, and when said wedges 25 are driven home they securely retain the locking-dogs in their engaging position with the closure.

When the vat is used for bleaching purposes, the lower face of the closure and the upper face of the supplemental bottom are covered, coated, or sheathed with copper, lead, or other suitable metals not affected by alkali or chemicals, as indicated by the reference character 26.

From the foregoing construction of vat adapted for bleaching and dyeing purposes a vat is set up which is unusually strong and durable, and a closure for the vat is set up which is so constructed as to resist the immense pressure necessary when circulating a liquid through the solidmass of material being treated. The constructing of the closure in the manner set forth prevents the bulging at the center thereof during the circulation of the liquid and the engaging of the lockingdogs with the margin of the closure, also prevents the closure from bulging at its edges. The closure when in position is always below the outlet of the receptacle, so that during the bleaching or dyeing operation the material remains submerged at all times, which is due to the fact that the quantity of liquid supplied to the vat is such that the level of the medium will never fall below the closure.

It is thought the many advantages of a vat for dyeing or bleaching purposes constructed in accordance with the foregoing description, taken in connection with the accompanying drawings, can be thoroughly understood, and it will furthermore be evident that changes, variations, and modifications can be resorted to without departing from the spirit of the invention or sacrificing any of its advantages, and I therefore do not wish to restrict myself to the details of construction as hereinbefore shown and described, but reserve the right to make such changes, variations, and modilications as come properly within the scope of the protection prayed.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is
