2 Claims.

This invention relates to apparatus for treat ing yarns and like materials and more particularly to apparatus of the closed kier type for treating such materials in-package form.

' are often of a corrosive nature. \Vhere the material to be treated is in the form of packages or other convenient unit form, it is desirable to apply a predetermined substantial pressure to the packages in order that all portions thereof may be uniformlysubjected to the action of the treating liquor.

According to the present invention, the apparatus includes a tank or kier formed of a suitable metal or metals. The sides of the kier are formed of one or more plates bent to form a tubular structure and the bottom is constituted by one or more members secured to'the side walls as by welding. Disposed in the kier is-a diaphragm 'member or holder plate which supports one or more perforated standpipes adapted to receive the packages of material to be treated and which also assist in directingthe flow of liquor through the packages. A presser plateortop plate is guided by each standpipe and bears against the top package of each stack. The presser plate may be urged against the top package by pressure exerted by the cover when closed. Alternatively, the presser plate may be attached to an actuating rod extending through the diaphragm member. and bottom wall of the kier and connected to. a suitable power device located out-' side of the kier, such as a piston and cylinder.

The presser plate thus can be moved downwardly to apply pressure to all of the stacks of packages simultaneously and can be retained in any desired position to maintain the packages under Suitable equalizing depresser plate and the several stack of packages whereby equal pressure is applied to each of the stacks.

An object of the invention is to provide a tank or kier for use in treating yarns and like materials, which tank can be easily and economically fabricated and which is rugged and capable of withstanding relatively high pressures.

Another object of the invention is the provision ofa kier having associated therewith apparatus for compressing packages of material I within'the' kier, which apparatus does not interfere with the opening and closing of the kier cover.

Another object of the invention is the provision of kier dyeing apparatus having power operated mechanism for evenly and uniformly compressing stacks of packages within the kier simultaneously and for maintaining them under readily controlled compression.

Various other features and advantages of the invention will be apparent from the following particular description and from an inspection of the accompanying drawings.

Although the novel features which are believed to be characteristic of this invention will be particularly pointed out in the claims appended hereto, the invention itself, as to its objects and advantages, and the manner in which it may be carried out, may be better'understood by referring to the following description taken in conproximately medially of one form of kier con-9 structed in accordance with the invention; v Figl. 2 is a top plan view of the kier shown in Fig.

Fig. 3 is a horizontal sectional view taken along line 3-3 of Fig. 1; and

'Fig. 4 is a vertical sectional view taken through another form of kier and showing also a novel power operated mechanism forcompressing the stacks of packages.

In the following description and in the claims, various details will be identified by specific names for convenience, but they are intended to be as generic in their application as the art will permit. Like reference characters denote like parts in the several figures of the drawings.

proper or the tank I is constructed preferably from a metal, such as stainless steel, which is not attacked by corrosive liquors, particularly those which are commonly used in the treating of textile materials. I have found that the so-called stainless steels are particularly'well adapted for forming kiers in view of their great strength, their suitability for welding, and their resistance to corrosion by liquors customarily used in treateat;

ing textile materials. However, the kier may be formed of any suitable metal, such as iron, steel, bronze, aluminum, Monel metal and others. The other portions of the apparatus may be formed from the same material as the kier or some other suitable material.

The side wall 2 of the kier is constituted by a metal plate bent into cylindrical form and welded to form acylindrical structure. In some cases it may be found desirable to use two or more plates but generally a single plate having a single weld-' ed joint will be found to be suitable. The bottom wall of the kier is constituted by a dished platelike member 3 having a boss 4, formed integral therewith or as a separate member Welded thereto. The bottom 3 is secured to the'lower portion of the side wall 2 as by welding, and preferably, the weld is a continuous onewhich not only pro? vides a joint of great strength, but also prevents the escape of liquor from the kier even under substantial pressure. V i

A ring 5, preferably of L-shaped cross-sectional shape, may be welded or otherwise suitably secured to the lower portion of the kier, which ring serves to strengthen and reinforce the lower end of the kier and provides convenient means for attachment of a plurality of supporting legs 6.

An inlet opening 7 is provided in the side wall 2 and an inlet conduit 8 registers therewith. An inlet opening 9 is provided in the bottom 3 and an inlet conduit Ill which may be in drawn or fabricated pipe extends therethro-ugh for admit-1 ting liquor into the kier. The conduits 8 and Ill may be secured to the kier I as by welding.

A removable diaphragm member l l, which may be formed as a stainless steel casting or as a fabricated member, is disposed in the lower portion of the kier and includes an upper walll2 and a lower wall i3 defining therebetween a manifold chamber I4. Where the member H is fabricated the walls l2 and I3 may be welded attheir peripheries. The lower wall l3 has an outlet opening l5 surrounded by a boss 58 which may be an integral portion of wall l3 or a separate member welded thereto. The boss l6 seats on the boss 4 surrounding the opening 9 in the bottom 3 and the opening I5 registers with the opening 9 in the bottom; the bosses may be connected by bolts H, which thus secures the diaphragm member H in position.

It will, be seen that the diaphragm member ll divides the interior of the kier to form a lower chamber l8 defined by the lower wall 13 and the kier bottom 3 and a treating chamber l9 defined by the upper wall l2 and the kier side wall 2. The diaphragm member H is of slightly less di-. ameter than the interior of the kier and, when. in position, terminates short of the side wall 2 of the kier to leave an annular passage 20 providing communication between the lower chamber l8 and the treating chamber i9. One or more tubular portions 2| integral with the upper and lower walls 52 and I3 of the diaphragm member II de-, fine passages 22 extending from the lower chamber l8 to the treating chamber l9.

A plurality of threaded openings 23 surrounded by depending flanges 24 are provided in the top wall l2, and a tubular standpipe 26; is threaded in each of these openings. Each standpipe is provided with a series of perforations 2? distributed throughout substantially its entire length. The standpipes 21 are adapted to receive one or more packages 28 of material to be treated, which packages are of generally ring-like form with central openings 29 whereby the packages may be telescoped on to the standpipes and arranged one upon the other to form a vertical stack. A suitable presser flange or cover plate 30 is provided for covering the top package of the stack and for maintaining the stacked packages under a suitable pressure.

The top plate 30- has an upstanding portion 3| adapted to abut the lower side of a cover 39 when the latter is in closed position on the kier, as hereinafter more fully described. A skewerlike extension 32 depends from and may be formed integral with the top plate 30 and is adapted to telescopingly enter the standpipe 26 for positioning the top plate 30. 'A standpipe head or end 33 has a reduced portion 34 threadedinto the upper end of the standpipe 26 and has a bore '35 adapted to receive the extension 32.

The head or end 33 may be tapered to facilitate telescoping the package 28 on the standpipe 26.

groove 31 in which is heated a gasket 38. A disclike cover 39 is provided for closing the top of the kier, Which cover is adapted to seat on the gasket 38, and has a liner plate 40 which may. be integral therewith or welded thereto, and which is adapted to fit snugly in the kier I. The cover 39 preferably is formed from a plate of in: corrodible material, as for example, stainless steel.

Surrounding and secured to the upper end of the kier wall 2 is 'a ring or band 4| on which is secured a suitable number of brackets 42. Swiveled in each bracket 42, as by a pivot member 43, is a bolt 44 adapted to enter a correspondingly position notch 45 in the cover 39 when the latter is in position on the kier. A nut 46, which may be provided with a suitable handle, is threaded on the bolt 44 for locking the cover 39 in position..

Secured to and depending from the cover is a pair of positioning pins 41 adapted to extend through openings 48 in lugs 49 secured to or integral with the ring 36. Also secured to the cover as by welding is a ring 54 by which the cover can be manipulated.

A sampling .pipe 5! may be extended through the cover 39 and is secured as by welding or threading and welding. A bleeder pipe 52 extends into the side wall 2 of the kier and may be secured as by welding or threading and Welding. Preferably the bleeder pipe is disposed immediately under and in abutment with the ring 36, as shown.

The operation of the apparatus thus far described is as follows:

Packages 28 of yarn, thread or other material are telescoped on to the several standpipes 26 and the cover plates 30 are assembled on the holders by inserting the extensions 32 in their respective The cover plates 30 drop down standpipes 26. into engagement with the top packages of the stacks and serve to close the central opening therein.

The cover is assembled on the kier by registering the pins 4'! with the openings 48 in the lugs 49 and the cover is locked in position by inserting Y the bolts 44 in the notches 45 and tightening the.

passages 22 and the annular passage into the treating chamber I9. The liquor then is forced through the packages 28 and the openings 21 in the standpipes and, then flows downwardly through the standpipesand into the manifold chamber I4 from whence it flows into the outlet pipe I0 and out of the kier; It will be understood that, if desired, the direction of flow may be reversed, in which case the liquor isintroduced through conduit 9 and flows in a direction reversely to that above described, the liquor being expelledthrough the conduit 1.

Referring now to Fig. 4, there is shown apparatus including a somewhat modified form of kier and having associated therewith, a modified mechanism for compressing, the stacks of packages. I

The kier IOI is formed with aside wall I02 which preferably is constituted by one or more plates of stainless steel or other suitable material,

' and a bottom wall which may be formed of similar material is secured to the side wall I02, as by welding. The ki'er is supported in a suitable manner, as for example, by aplur'ality of legs I04 secured to the bottom wall I03 and/orthe side wall I02.

The bottom wall I03 is formed with a central opening I05 surrounded by a flange or boss I06, and a closure member I01 has a projecting portion I08 snugly seated in the opening I05. The

' closure member I01 has a flange I09 which is secured to the boss I06 as by bolts I II). Formed in the closure member I01 is an opening II5 with which. registers a conduit H6 provided with a flange I I1 which is suitably secured to the closure member I01.

The bottom wall I03 is provided with a boss portion II 8 defining an outlet opening H9 in which is suitably secured an outlet conduit I20.

Disposed inthe lower portion of the kier is a diaphragm member I25 having an upperwall I26 and a lower bottom wall I21 defining therebetween a manifold chamber I32. Depending from the lower wall I21 is a conical flange I28 adapted I, to seat in a conical seat I29 formed in the closure passage I3I provides communication between a lower chamber I33 defined by the lower wall I21 and the bottom I03 and a treating chamber I34 defined by the upper wall I26 and the kier side wall I02.

The upper wall I26 is provided with a plurality of threaded openings I35, each of which receives a standpipe I36 which is supported in vertical position by the diaphragm member I25. Each standpipe I36 is provided with a series of perforations I31 distributed throughout its length which provide communication with the interior of the standpipe.

Each standpipe is adapted to receive a stack of packages I40 and a presser flange I4! is telescopingly received on the standpipe and adapted to bear against the top'package of the stack. -A presser plate I42 is provided for applying pressure simultaneously to all of the pressure flanges MI and is'formed with suitably-disposed openings I with equal force.

wherebythe plate I42 can-be telescoped over-all of the standpipes I36. r

A spring I43 may be interposed between each presser flange MI and the presser plate I42 .whereby the pressure may be transmitted from the presser plate to the several pressure flanges Preferably, the. opening I45 in the presser plate I42 is of sufiicient size to provideconsiderable clearance for the presser plate I42 thereby to prevent binding. For this reason, it may be found desirable to provide a seating plate I44 to serve as an abutment for the upper end ofthe. spring I43. I

The presserplate I42 is carried by a control rod I having a reduced threaded end I5I extending through an opening I49 in the presser plate; a nut I52 secures the plate in position. The actuating rod I50 is received in and guided by an upright guide tube I53 suitably secured in an opening I54 in the upper wall I25 as by a flange I55 attached to the upper wall 126. The rod I50 is guided in a bearing member I56h'aving a recess I51 adapted to contain a sealing material I58. An adjustable gland I59 is forced against the packing I58 by one or more screws I60 to'therebyseal the rod I50 in the bearing I56. V I

The rod- I50 is axially slidable in the bearing I56 and its travel downwardly is limited by a I collar I6I secured to the lower face of the presser plate I42 and positioned to abut the top end of the guide tube I53.

The rod I50 extends through'the opening II5 in the closure member I01 and projects through an opening I1I in a boss I10 which preferably is integral with the conduit II6. guided in a sealed bearing I12 generally similar to the bearing provided at the top end of the tube I53. It will be noted that this arrangement of Widely separated bearings firmly supports the rod, I 50 against displacement or bending.

The rod I50 extends through an opening I14 in a cylinder I15 and is provided with a piston I11 snugly fitting the cylinder I15. The opening 114 is sealed by a sealed bearing I18 generally similar to the bearing I12. The lower'end' of the cylinder I15 maybe closed by an end plate I16 in a suitable manner. The cylinder I15 may be rigidly positioned relatively to the kier by one or more connecting bars I82 attached to the cylinder. and to a convenient portion of the kier, as for example, the closure member I 01.

"Conduits I80 and I8'I- lead into the cylinder I15 on opposite sidesof the piston I11 respectively, whereby an actuating fluid, such as steam, compressed air or the like, can be admitted on either side of the piston to effect upward or downward movement as may be desired.

Secured to the upper end of the side wall I02 is a ring I90 having an annular groove I9I in which is seated a gasket. I92. A disc-like cover I93 is adapted to rest on the gasket I92, The ring I90 is provided with a plurality of projecting lugs or ears I94 in each of which is pivoted an eye bolt I96 swinging on a pivot pin I91. Each eye bolt is adapted to enter a notch or slot I98 in the cover I93 and receives a nut I99 by which the cover may be clamped securely in position.

Extending through the cover is a sampling pipe 200 which may be secured in the cover as by welding or threading and welding. A handle ring ml is also secured to the cover as by welding.

A bleeder pipe 202 extends through the side wall I02 of the kier and may be secured as by welding or threading and welding. Preferably, 75 I the'pipe 202 is disposed immediately under the ring I and may be secured thereto as by welding.

The operation of this form of apparatus is as follows: v r

The packages of material to be treated are telescoped on to the standpipes 136 in stacks, as shown in Fig. 4, whereafter the presser flanges I4I, springs I43 and seating plates I44 are telescoped on their respective standpipes. The presser plate I42 is then placed down over the standpipes with the standpipes extending through the openings I45, the central opening I49 in the presser plate being telescoped over the threaded end I5I and the securing nut I52 being threaded on to the rod I50. Thereafter, the cover'I93 is placed in position and secured by the eye bolts I92.

After the cover has been secured, a pressure fluid is introduced under predetermined pressure, through the conduit I80, into the interior of the cylinder I15, which causes the piston I TI to be depressed and draw the rod I50 downwardly. This depresses the presser plate I42 to thereby exert pressure on the springs I43 which in turn force the presser flanges I4I against the top packages of the respective stacks. Thus all of the packages in the stacks are placed under substantially equal compression.

When the desired compression of the packages has been effected, a suitable treating liquid, as for example, dyeing liquor, is introduced into the conduit H6 and flows through the opening I29 and the chamber I32 and into the several standpipes I 36. The liquor passes through the perforations I31 and outwardly through the packages into the treating chamber I34. The-liquor then returns through the annular passage I3I and chamber I33 and is discharged through the conduit I20. Inasmuch as the piston I" is positioned positively by the compression fluid, the packages are maintained under constant compression throughout the treating operation.

If desired, the flow of treating'liquor can be reversed, in which case it passes into the conduit I20 and inwardly through the packages and returns to the standpipes and the chamber I32 and passes out through the conduit I I6.

When the treating operation is'completed and the treating liquor drawn off, the pressure on the packages is released by releasing the pressure on the fluid above the piston and by introducing a pressure liquid through the conduit l8! which drives the piston Ill and connecting rod I50 upwardly. The presser plate can then be removed and the seating plates I44, springs I43 and presser flanges I4I removed, whereupon the packages I40 can be removed from their respective standpipes.

It will be seen that the present invention provides kier dyeing apparatus which is relatively simple and inexpensive to build but which is rugged and capable of standing up under the customary conditions of use. Allof the parts which are subject to contact with the treating liquors are formed of incorrodible material, such as stainless steel, and thus the apparatus is not readily attacked by the treating liquors.

The diaphragm member also provides a convenient support for the standpipes and serves, with the standpipes, as a rigid, positively positioned support for the packages of textile mate-,

The novel mechanism for compressing the packages permits any degree of controlled prede-' termined pressure to be applied simultaneously to all of the stacks of packages. The equalizing arrangement insures that all of the packages'in all of the stacks will be under identical pressures and thus all portions of the material treated will be uniformly impregnated and acted upon by the treating liquor.

The mechanism for compressing the packages is entirely separate from the kier cover and does not interfere in any way with the opening or closing of the cover, Hence, the packages can be compressed either before or after the kier is closed. Furthermore, the kier can be opened or closed without the necessity of manipulating any connection between the cover and the package compressing mechanism.

While certain novel features of the'invention have been disclosed and are pointed out in the annexed claims, it will be understood that various omissions, substitutions and changes may be made by those skilled in the art without departing from the spirit of the invention. I a
