6 Claims. (Cl. 68-198) I This invention relates to apparatus for dyeing,

bleaching and similarly processing flbrous materials, such as yarn and thread in cop or package form; and particularly to means for facilitating the placing of the packages on the standpipes in a kier or the like.

One object of the invention is to provide extension means for the standpipes of the kier for supporting the topmost packages of the series strung thereon while permitting the material therein to be compressed.

Another object is to provide an extension member adapted to be maintained elevated above the end of a standpipe in the kier and to telescope longitudinally within the standpipe when the packages are compressed thereon to bring their material into uniform density.

Another object is to provide extension means for the standpipes with means for automaticallymaintaining it in extended position while permitting it to slide downwardly therein without exerting undue resistance to the compression of the packages.

Another object is to provide an extension member for the standpipes which is of simple construction and adapted for use to facilitate the placing of the packages on the standpipe and their removal therefrom without particular care or skill on the part of the op l' tor. Further objects of the invention are set forth in the following specification which describes a preferred form of construction of the extension member with one modification thereof as illustrated by v the accompanying drawings. In the'drawings:

Fig. 1 is a side elevation of a dyeing vessel or kier shown with its casing and cover as partly broken away to illustrate the yarn packages .held on the standpipes therein and the present improved extension member applied touse therewith;

Fig.2 is an enlarged axial sectional view showing the upper end of one of the standpipes of the kier with the present improved extension member applied thereto and illustrated in extended relationship with the ackages in place thereon;

Fig. 3 is a similar view showing theextension member in telescoped relationship with the packages compressed on the standpipe;

Fig. 4 is a further enlarged transverse sectional view on line 4-4 of Fig. 2 looking in the direction indicated by the arrow;

Fig. 5 is a view similar to Fig. 2 showing a different form of construction of the extension memher and its retaining means; and I Fig. 6 is a transverse sectional view of the same on line 66 of Fig. 5.

In the present approved practice of dyeing standpipes rising from a false bottom in a kier or similar vessel. A plurality of standpipes are arranged in communication with a chamber beneath the false bottom of the kier which is connected through a circulating system with a source of supply of the dye-liquor 'or other fluid for processing the material in the packages. Usually, a pump circulates the dye-liquor or other fluid through the chamber in the bottom of the kier to cause it to flowinto the perforated standpipes and be forced outwardly through their orifices into'the material of the packages surrounding the standpipes. The dye-liquor may be exhausted from the upper compartment of the kier. recirculated through its lower compartment and into the standpipes; or the reverse circulation may be set up with the liquid forced into the upper compartment of the kier, thence into the packages and down through the standpipes to be exhausted from the lower compartment of the kier.

In order that the yarn or other material in the packages surrounding the standpipes may be dyed uniformly it is necessary that the Packages be compressed longitudinally of the standpipes to bring all of the material to a uniform density. This is usually accomplished by providing resiliently-operated means on the cover of thekier adapted to seat against the topmost package of each series to compress the material in the whole series of packages when the cover is closed and fastened down against the open top of the kier. It is thus readily to be seen that in order to eflect a considerable compression of the yarn in the several packages mounted on the standpipes certain of the packages must be arranged above the upper end of each standpipe to adapt them to be slid downwardly as the material in all of the packages is compressed. The compression means is also designed to seal the opening at the upper end of each stack of packages to prevent the most package in the series.

rangement, however, the extension membercannot be employed as a holder or supporting means for centering the last few packages applied to the series above the end of the standpipe. That is to say, the packages last applied to the upper end of the stack must be located carefully in alinement with those beneath and thereafter the extension member is placed in position with its end plate or disk overlying the last package in the series.

It is the object of the present invention to provide an improved extension member which may be positioned in elevated position and maintained in extended relation to the upper end of the standpipe to serve as a guide for placing. thelast packages on top of the stack whlle being capable of allowing these last packages to be forced downwardly to compress the mass of material in all the packages surrounding the standpipe. For

this purpose I provide an extension member slid-- able longitudinally with respect to the upper end of the standpipe and having means for automatiially retaining it in its extended relationship 'while adapting it to be telesooped within the end of the standpipe when the packages are compressed by the closing of the cover of the kier.

vessel into an upper compartment 5 and a lower compartment 6. Acover I is employed for closing the open top of the kier with the'usual With such an ary a reticulated fabric sleeve or stocking s. The

helical spring I; distends the stocking s in cylindrical form to adapt the yarn to be wound therearound and the resiliency of the spring permits the tube or core 0 to be contracted longitudinally when the yarn mass is compressed lengthwise of the package.

Referring particularly to Figs. 2, 3 and 4, the present improved extension member 24 for the standpipes 3 comprises in a preferred form a the ends'of the cop-tubes C on which the packarrangement of bolts 8 for clamping it in closed position thereagainst. The kier 2 may be supported from legs or standards 9 and suitable supply and exhaust pipes, indicated generally at IU, communicate with its upper and lower compartments for the circulation of the dye-liquor or other fluid through the kier. The standpipes 3 are screwed into openings in the false bottom;

4 in communication with the lower compartment 6 and are perforated with a multitude of relatively small holes l2 spaced around their sides.

- in the sides of the sleeve IE to limit the sliding movement of the latter under the force of the spring 20. The arrangement of the compression means on the under side of the cover I is shown more in detail in United States Letters Patent No. 1,511,380 dated October 14, 1924. and therefore needs no further description herein.

The yarn or other material tobedved or e wise treated with liquid is wound into cylindrical packages P supportedon porous hollow CulcS ur tubes C which are preferably constructed to adapt them to contract longitudinally. Such a well known form of contractible cop-tube is described in Reissue Patent No. 13,223 of March 28, 1911, as comprising a helical band or spring b enclosed by -wise suitably secured thereto.

rods 26 are adapted to slide downwardly within the standpipe 3 in contact with its inner walls while exerting a friction thereagainst. As shown in Figs. 2 and 3, the upper end of the standpipe 3 is partially closed by means of a plug 38 having a reduced portion 3| threaded to engage threads on the interior of the standpipe. An axial bore 32 extends through the plug 30 for permitting egress of the fluid from the end of the standpipe to cause it to flow into the interior of the package or packages mounted thereabove, see Fig. 3. The rods 26 extend through bores 33 in the plug 30 which are spaced aroundthe central bore 32. Preferably, the bores 33 are spaced at a radial distance from the center o'f'the plug 30 slightly greater than the distance of the holes 28 from the center of the boss 25 in which the ends of the rods are mounted, whereby to cause the rods to exert a slight resistance to their sliding motion through the plug 30 to actas friction means for holding the extension member elevated to any positionto which it may be raised. The lower ends of the rods 26 are fastened together in spaced relationship by means of an annular membar or spreader 35, see Fig. 4, welded or other- The member 35 also serves as a stop or detent to limit the upward movement of the rods through the bores 33 inthe plug 30 whereby to prevent the extension member 24 from being disconnected from the standpipe 3. The under side of the boss 25 is provided with a. plurality of grooves extending radially from its axis to its periphery between the rods 26 to serve as ducts for permitting a free flow of the liquid through the axial bore 32 in the plug 30 should the boss become seated against the top of the plug. The method of operation of this form of construction of the invention is as next explained.

It will be understood that the standpipes 3 are arranged in concentric rows spaced around the interior of the kier 2 at intervals to provide for reception of the packages P stacked thereon with a slight amount of clearance between their peripheries. The standpipes 3 reach nearly to the edge of the opening at the top of the kier 2 and the extension members 24 provide for placing several packages above this level. That is to say, in

topmost packages on the standpipes. In com"- pleting the stacking of the packages P on the several standpipes 3 the boss 25 of each extension at 43 for receiving the cup-like plunger or thlmbl'e member 24 serves as a guide to direct the added packages into alignment with those beneath sothat the ends of their cores or cop-tubes C will be in register to provide for the free flow of the dye-liquor or other fluid therethrough.

After all the standpipes have been supplied with the packages P of yarn or other material in the manner as above explained the cover i of the kier. 2 is applied to its open top by lowering it with a tackle connected to an eye-bolt H at its center. As the cover 1 is lowered against the top of the kier 2 it is guided into place by dowel pins i3, shown in Fig. 1, to register its rim with that of the kier, and usually a ring it of packing material is provided to -seal the joint therebetween.

The clamping bolts 8 are then fastened to secure the cover in place. As the cover 1 is loweredinto closed position the compression plates or disks it will engage the bosses at the upper ends of the extension members is to slide the latter downwardly to telescope them into the standpipes 3. The compression disks ll will also contact with the ends of the topmost packages P surmounting the standpipes 3 and force the latter downwardly to compress the mass of yarn in the whole series of packages P. The compression is exerted by the springs 20 which may yield slightly during the compression as the mass of material in the packages is brought to a, uniform density. With the packages P thus held under compression in all of the stacks surrounding the several standpipes 3, the dye-liquor or other fluid may be circulated through the kier 2 by means of a pump, not herein shown, to force it radially through the packages either from their interiors outward whom the outside of the stacks radially inward. By compressing the yarn in the packages to a uniform density a more uniform or level dyeing result is secured, the fluid being prevented from escaping between the ends of adjacent packages or from flowing too freely through some portionsof the mass and thereby causing the yarn to be dyed with the color varying in shade.

In unloading the kier after the dyeing or other treatment of the yarn is completed the order of procedure is reversed. That is to sayl the clamping bolts 8 are released and the cover I raised ofi from the kier 2, the packages P then being removed from the standpipes 3 in any suitable manner. Thereafter the extension members 24 may be raised or slid upwardly in position to serve as guiding meansfor applying the next batch of package'sto the standpipes with the uppermost ones elevated above their ends. Since the extension members 24 are at all times connected with and prevented from being removed from the standpipes the danger of their misplacement, loss or damage is obviated.

Figs. 5 and 6 show a modified form of construction of the extension member in which the boss or guiding element 40 is supported at the end of a single rod 4| slidable through an axial hole in the plug 42 at the end of the standpipe 3. The friction means for holding the extension member in elevated orextended relationship with respect to the end of the standpipe 3 may comprise a spring-pressed element such as the plunger 44 engaging against the side of the' 'od 4|. For this purpose the plug 42 is bored radially 44 which is forced radially inwardby means of a helical spring 45 held in the bore 43 by a screw 48 threaded thereinto. With this form of construction the plug 42 may be provided with a plurality of bores M for egress of the fluid from the end of the standpipe 3.

In either formof construction as herein shown, or with other modifications in the structure and arrangement of the-parts, the present invention provides an, improved extension member for guiding a plurality of packages to locate them above the upper ends of the standpipes withtheir openings alined with those in the cop-tubes of the packages therebeneath, No especial skill or expertness is required to operate the device, the extension member being easily raised to elevated position by sliding its rods upwardly through the plug at the end of the standpipe. The friction means acting on therods of the extension mem= ber serves to automatically retain it in any posiit is to be understood that other modifications may be made in the structure and arrangement of the parts of the extension member and its supporting means without departing from the spirit or scope of the invention. Therefore, with-=- out limiting myself in this respect, I claim:
