To alz whomit concern .Be it known that 1, JAMES H. SNITT, a

subject. of the King of'England, residingat Philadelphia, in the county of Philadelphia and State of Pennsylvania,have invented cert-am new and useful Improvements in Processes of Dyeing, of'which the follow dye liquor in a yat at a point nearthe surface of the latter and in moving ,the goods to,.be dyed av circular. path around the point of agitation andinto and out of; the dye liquor in a manner tocause the liquor to pass first in one direction through the goodsiand then, in a reverse direction so as to thoroughly penetrate and impregnate the goods with the dye liquor, at the same time without the usual. knotting or 1 inj uring of the goods. Other objects and stepswill. be more'fully pointed out-in the followinggdescription and with reference to "the accompanying drawingfoi ming a part of vthis specification. The apparatus employed in carrying, out this process is similar to that of co-pending application Serial Number-,657\ ,0 8 t, and as seen in the drawing of this invention 0on sists in .a vat 1 which contains ,the', dye liquor: ,The bottom 2 of the vat issemicircular in .CI-OSSJSQCtlOII and between this bottom and the peripheral wall 3 of the cars rier for the goods is leftsufiicient spacezfor free circulation of the dyeliquor. The carsuitably connected ,tocircular .imperforate end walls 5 and.imperfora te radialparth tions v6. .The latter divides the carrier into compartments A,B, O,.D,-E, and F. The end walls 5 of the carrier are journaled-on a shaft 6 and any suitable means-"may be employed for rotating ,thef'carrier thereon in the direction indicated by arrow Z.

Radiating from the shaft 6 are imperforate circulating blades 7, which with imperforate end walls 8 constitute the agitating or circulating means. Any means may be provided for rotating the shaft and agitator in the direction indicated by the arrow. X; that is, in a direction reverse to that in which the carrier rotates.

:Inlcarrying out the processfthe carrier and ag tatorvalre rotated as respectively indicatedbyfthe arrows Z and X the vat being previously filled 'with' dye or other liquor. The goods, tobe dyed are compacted into the compartments A, 13,0, 1), E and F,

but leftloos'e enough nqt ito interfere with the ,free, passage therethrough of the .dye

liquor. VVhenthe compartment A is at the zone Gr, the compartments'F, E and D are respectively at the zones L, K, andJ, and

all submerged or-partly so in the dye liquor,

The agitators 7 rotating in 'the direction of the arrow X, draw the dye liquor through the compartment A from the erterior thereof to the center of the carrier as indicated by arrows and from the center, tl1e agitators draw the .dye liquor through the compartment, I) to the exterior-of the carrier-as indicated by ,arrows. The perforated walls of the oompa-rtments permit, this circulation. Like wise, the agitators draw' the dye; liquor through the compartment F from the exteridr of the carrierto the center of the carrier; and ,force the dyeliquon froni the center of the carrier through'the compart ment E to the exteriorof thecarriera' This circulation of the dye liquor by the agitator is confined to the paths indicated,by the end walls; and partitions, which inthemain should. be imperforater It will be' observed that the circulation of thejdyejli 'quor is most perfect when one of the partitions Gb'ecomeslocatedin the vicinity of' amedial line between the zones L and 5K, as illustrated, and when soflocated,the partition offers .an obstruction around which the dye liquoris compelled to flow thereby maintaining a continuous circulation of the liquor from left toright in the'upper por- -tion-o f theyat. and fromrightto left along the, bottom ,wall. 2 of the vat.

liquorifrom the compartments A, 13,0 and D or the portions thereof not submerged drains into the central chamber of the carrier, except for a small portion that escapes through the exterior walls of the same. As the carrier slowly rot-ates to bring the compartments F, E, D, and C adjacent the zones G, L, K and J respectively, the dye liquor circulates from the carrier exterior through the compartments F and E to the The dye carrier center, and from the carrier center 45 tion, in passing the goods to be dyed through tending to break the direct flow at certain is claimed as new and desired to be secured points, but in general the circulation of the dye liquor will'be as described, and the bulk of the liquor will take the paths of flow indicated.

At the zones L and G, the dye. flows throu h the goods in one compartment in one dlrection. This dye liquorthen drains from the said compartment as the latter leaves the vat, and as the com artment is again submerged at the zones J and K, the dye liquoragain flows through the goods, but in a reverse direction. The carrier turns slowly so as not to roughen or tangle the goods in the compartments and to not interfere with the described circulation of the dye liquor. On every revolution of the carrier,

the dye liquor passes twice through the goods in the compartments, once in one direction and then in a reverse direction.

.. ,Of course it will be understood that the invention is not restricted to dyeing, but is applicable generally to impregnating such as washing, coating or otherwise. The mvention is particularly adapted to treatingknit' goods, as stockings, but may beem- .ployed for treating any other goods or articles.

Having fully described the invention, what by Letters Patent is 1. A process of dyeing, consisting in agitating the dye li nor to produce currents thereof toward an from the point of agitasaid currents to-cause the currents to pass first in one direction and then in an oppo site direction through the goods, and in obstructing the flow of the liquor between the point of agitation and a point adjacent the outer limittherefrom in the path of travel of the goods. I i

2. A process of dyeing, consisting in agi tating the dye 1i nor to produce currents thereof toward an ,from the pointof agitation, in rotating the goods around the point of agitation to cause the currents to pass first in one direction and then in an opposite direction through the goods, and in obstructing the flow of the liquor between a point adjacent the point of agitation. and a point adjacent the outer limit therefrom in the path of travel of the goods.

3. A process of dyeing, consisting in agitating the dye liquor to produce currents thereof toward and from the point of agitation, in rotating the goods around the point of agitation into and out of the liquor to cause the currents to pass first in one direction and then in an opposite direction in one direction and then in an opposite direction through the goods.

5. A process of dyeing, consisting in agitating the dye liquor to produce currents thereof toward and from the point of agitation, in immersing the goods-in the liquor on one side of the point of agitation and withdrawing them on the opposite side thereof thereby causing the currents to pass in one direction and then in an opposite direction through the oods, the direction of agitation being opposite to that of travel of .the goods.

6. A process of dyeing, consisting in agitating the dye liquor to produce currents thereof toward and from the point of agitation, in surroundingthe point of agitation with the goods to be dyed, separating the goods into lots in a manner to prevent flow of the liquor directly from one lot into the other, and in moving the goods about the point of agitation to cause the lots treated by one of said currents to be subjected to the other thereof. y

In testimony whereof I afiix my signature in presence of two witnesses.
