"Referring to the drawin g' for a complete tion" there showi'n'; a tank lotion-the dye. or

. other treatingliquoris provided being-su eported by a suitable frame structure 11:" I e 'For acomplete understanding of the na- Fig. i tiona view. similar tothat of Fig. 1 but'i-llustrati-ng the formation'of theliquid cushion; I

and side walls merging with each other and,

forming a curved or cylindrical bottom part which may be provided with a conduit 12 for admitting and draining off the liquor. A cover plate 13 overlies the tank, thus forming an entirely enclosed interior compartment.

. doorway.

The interior of the tank compartment is somewhat elongated in vertical dimension facilitating loading-and unloading of the drum.

The receiver drum 16 is preferably in the form of a cylinder having foraminous walls I to permitpassage of the treating liquor and axis of the drum being mounted for rotary movement within the tank. The drum also is preferably constructed of non-corrodible sheet metal and may be divided into a plurality of interior compartments so as to separate the goods into different-lots thus to facilitate handling and treatment thereof. For this purpose in the embodiment shown, a partition 17 extends across the interior of the drum dividing it into two separate compartments, each of which is provided with a doorway having a closure 18. The drum is mounted in the tank by means of a swinging supporting frame structure including spaced triangular brackets 19, onebeing disposed at either end of the drum and mounted for swinging movement about one apex on a driving shaft 20 suitably mounted in bearings secured to the tank frame. The drum is mounted on the free or swinging apices of the brackets 19 by means of a drum shaft 21 forming the and extending beyond the end'walls thereof for connection to the respective brackets 19. The drum is thus mounted for up and down swinging movement within the tank with the end -brack-' ets 19.

Some convenle'nt' holstmg mechanism for raising and lowering the drum is desirable,

the embodiment shown including connecting -links 22 connected at opposite ends of the drum and to cranks 23 mounted upon a shaft 24 positioned above the drum. [This shaft may be driven through a worm wheel 25 mounted thereon and a worm 26 driven by a shaft 27 which may be operated either by hand or by power. It will be observed that the liquor tank is proportioned so as to per:

, mit raising or lowering of thedrum therein while sai'd drum will be fully enclosed in raised, intermediate or lowered positions.

I Agitating movement of rotation, which may be continuous in either direction or oscillatory, is imparted to the drum through suitable mechanism such for example, in the embodiment shown, as the large spur gear 28 mounted adjacent one end of the drum upon shaft 30 is driven through a worm wheel 31 mounted thereon which in turn is driven by a worm mounted upon a shaft 32 within a housing 32, the shaft being driven from the driving shaft 20 through a pair of intermeshing bevel gears 33. S1nce the driving mechanism for the drum is mounted upon the swinging drum supporting frame, it will therefore be operative to rotate the drumin raised or lowered position or in any intermediate position within the tank.

For the purpose of effecting a satisfactory agitating or turning and separating or like mechanical action upon. the goods under treatment, andfor effecting control of the de-' gree of agitation undervarying' conditions of treatment and of character of goods, a novel receiver drum is provided including a novel arrangement of'agitators or batflesineluding agitator plates 34 extending inwardly from the peripheral walls of the drum and preferably mounted upon and supported thereby. There-may be any preferred number of these agitator plates to effect the desired mechanical'action, two being a satisfactory number in each compartment of a two-compartment drum such. as shown. .The agitator plates 34 may be of any suitable form of construction sufliciently strong towithstand the stresses thereon and to avoid damage to the goods under treatment. A convenient preferred construction is shown, being of flattened tubular form with rounded edge and secured inposition by means of screws or similar securing means 35 extend. ing into the outer edge wall of the tubular-- agitator member, said edge wall lying in contact with the inner surface of the peripheral wall of the receiver drum. This arrangement provides an entirely smooth outer surface which comes into contact with the goods under treatment, there beingv no protruding flanges or other projections which might baflies 36 are provided. These agitators,

which may be in the form of plates, transect the spaces of the receiver drum, the outer ,edges thereof being disposed inwardly of 'the peripheral wall of the drum and spaced fromthe'inwardly disposed edges of. the outer agitator plates 34. The inner and outer agitator plates are disposed in staggered relation relative to each other, that is, each outer agitator plateis spaced angularly from the adjacent inner agitator plate so as to facilitate passage of the goods under treatment throughout the receiver compartment and to efl'ect the desired mechanical action thereon.

A preferred manner of supporting'the inner agitators 36 is disclosed, includin outer supporting bars 37 extending longitu inally of the drum and supported in any desired manner in the drum walls. The outer edges of the agitator plates are connected to these supporting bars 37 while the inner edges are, supported by the longitudinal drum shaft 21.

The division partition or plate 17 is pro- 1 vided with apertures 38 extending r through and preferably positioned at some distance outwardly from. the center of the partition where the centrally dis osed baffics 36 are located but an imper orate area: 23 or, zone 39 is provided on this partition lying erahle rotation of the drum. The perforations-v 38through the partition 17 are grouped outwardly toward the drum periphery beyond the imperforate zone 39,'-and permit some circulation of the liquor between the adjacent drum compartments as the drum rotates, but circulation in this respect is considerably restricted; that is, circulation through the partition 17 from compartment to compartment is considerably restricted by the: imperforate 'zone 39. owever, the peripheral shell 18 of the drum is provided with perforations 40 leading therethrough to the several .9 receiver compartments and providing passageways permitting circulation of the liquor as the drum rotates in the treating liquor in the tank, this circulation taln'ng place out wardly from the receiving compartments into the tank and inwardly from the tank to the receiving compartments.

' Th1s arrangement of the bullies from several standpoints. One advantage is that the flow of the treating liquor to and from the several receiving compartments is uniform during operation of the receiver drum with consequent increased uniformity of'treatment of the goods within the several compartments. 'By means of this arrangement, the treating liquor within the liquor tank and within the several compartments is maintained uniform in mixture and in physical characteristics throughout the treatment.

By meansofthe' arrangement described, the

p and perforated compartment walls is advantageous circulation of liquor between the receiving compartments and the liquor tank is promoted and increased while the circulation from compartment to compartment is restricted.

All of the dyeor other treating liquor of the liquor tank is thus more effectively utilized and the whole body of the liquor is kept uniform, and redistribution is facilitated as parts of the liquor become partially exhausted.

- A further important advantage of the arrangement described is accomplished by the formation of the watercushion mentioned. When the drum is rotating in a clockwise direction in Fig. 2. as soon as the imperforate' zone 39 passes above the liquor line, the liq- 'uor is'entra-pped in the trough-like recess betweenthe partition and the baffle 36 thus forming the liquid cushion 41 into which the goods will move as rotation continues reducing direct contact with the metallic surfaces and not only'a-voiding injury to the goods which are often, of delicate character but also functioning to assist in the turning and separation of the goods, assuring more uniform treatment. This increased turning effeet is accomplished in part due to the 'tendency of the goods to ,flbat in the liquor of the liquid cushion, and in part due to the action of the bafile 36 and of drum rotation.

It will-be observed that the cushioning action of the liquid cushion 41 may be variant,-

dependent upon the position of the liquor level within the rotating drum; Take, for example, the condition wherein the liquor level is above the axis of the drum and nearly but not quite high enough tosubmerge the tumbler member 36 when the latter extends vertically upward, in which condition the effect of the liquid cushion will be very small, practically at a minimum. When, however, the liquor level is below the axis of the drum, as shown in Fig. 2, the effect of the liquid cushion is quite different, due, for one reason, to the fact that there is not much liquor above the partition '17 forthe goods to float in When said partition reaches horizontal position. The cushioning effect may thus be graduated between the firstand second mentioned conditions merely by raising thereceiving .dr-um as desired, by means of the drum hoisting mechanism. It will be observed, furthermore, that the cushioning arrangement de scribed exerts some cushioning influence, even though the cushion pocket-is entirely 'submerged when the drum is rotating low with in the liquor, due to the iin'perforate Walls jof-the tumbler 36 and the partition 17. This, cushioning effect would not be present under I conditions where either the partition or turm bler are perforated because such perforations wou' d permit free passage of the liquor.

A further advantage of the arrangemeht of bafiies and perforations in the-partition 17 is that a smooth rather than a perforated".

surface'is provided at the central part of the partition on which the goods may move as rotation of the drum progresses.

The operation of effecting the mechanical action upon the goods as the drum rotates will now be apparent. As the drum rotates in the treating liquor there is considerablemovement of the goods within the drum, and as the moving goods contact with the inner agitators 36 and the outer agitators 34 there is considerable tendency to turn, to separate and to open up the goods to the action of the treating liquor, even when each compartment of the drum is entirely submerged in the liquor. This agitating action may be materially increased however when the liquor does not entirely fill the compartment due to the tendency of the goods to float or come to the surface. Largely because of this floating tendency, the agitation is accentuated when the liquid surface is low within the receiver compartment, the lower the surface the greater the' agitating effect, and the higher the surface the smaller the agitating effect.

It will be observed that the goods will be lifted upon the rising side of the partition or compartment wall 17 as the drum rotates, and there will be considerable similar lifting effect also by the outer agitator plates or baffles 34. After the goods have been lifted by the partition 17 to a certain elevation, they will tumble toward and over the inner baffle or agitator 36 and against the liquid cushion 41 which cooperates to effect the desired mechanical action as the goods fall by gravity. Similar mechanical action is also effected upon the goods which are lifted by the outer agitator plate 34 which lags angularly behind the inner agitator plate 36. In the latter instance, the goods will fall from the angularly lagging plate 34 toward and at least partially into contact with the inner agitator plate 36 and cushion 41, thus effecting the mechanical action referred to. If the liquid is so high within the compartment as to sub merge the inner agitator plate 36 at the moment the goods tumble as described, said goods'will, of course, not fall into direct contact with the inner agitator plate due to their buoyancy or tendency ,to float inthe treating liquid, and the turning and tumbling or like mechanical action upon the goods .will, therefore, not be so great. Also the mechanical tumbling and tur'ningaction upon the goods is additionally promoted as the goods fall from the inner bajiies 36 outwardly against the outer bafliles34 at the descending side of the receiver drum. This tumbling mechanical action upon the goods thoroughly turns and separates them, thus facilitating the equal treatment of all parts thereof. Due to the tumbling mechanical action caused by the baflies 34: and 36 as above described, these members may be termed tumbler members or tumble-boards.

By means of the construction and arrange ment described, itwill be seen that the me- I chanical action upon the goods under treatment may be varied or controlled at will to meet varying conditions of service by simply necessary to vary the level of the dye or other .liquor within the dye tank. It is therefore a simple matter to control the treatment to suit goods of different character or quality,

or to effect different results where such revenient and full use of the baffle and liquid cushion construction.

As above suggested, it will be apparent will have a greater or less mechanical effect upon the goods dependent upon the level of the liquor within the drum. Due to the buoyancy of the goods with a high liquor that the baffle as well asthe liquid cushion level, the baffle will have but little eficct in mechanically opening up the goods while with lower liquor levels, this action becomes more pronounced. In the hoist type of machine, this increase or decrease in mechanical action may be easily brought about in any degree from a maximum to a minimum merely by the simple operation of raising or lowering the drum within the liquor tank. In the non-hoist type of machine similar variation in the mechanical action may be brought about by adjusting the level of the treating liquor within-the liquor tank, but this is much more difficult of'satisfactory ac complishment than in the hoist type of machine. I

In some classes of production, it is satisfactory to maintain constant liquid level and therefore the non-hoist machine will operate 15 creasing the dye bath and Without interfering with formulas, permitting the dyer to secure just the degree and duration of mechanical action that may be required.

Since certain changes may be made in the above construction and different embodiments of the invention could be made Without departing from the scope thereof, it is intendraising or lowering the drum, it being una level of the treating liquor so as to vary the' ed that all matter contained in the above description or shown in the accompanying drawings shall be interpreted as illustrative and not in a limiting sense; a
