E. V. HAYES-GEATZE MACHINE FOR' USE IN SCOURING EITHER wooL AND OTHER ANIMAL FIBERS OR VEGETABLE FIBERS Filed Dec. 21, 1931 EM E Patented June 20, 1933 UNITED STATES PATENT FFEE EUGENE VICTOR HAYES-GRATZE, OF LONDON, ENGLAND MACHINE IEOR USE IN SCOUBING EITHER WOOL AND OTHER ANIMAL FIBERS OR Application filed December 21, 1931, Serial No.

VEGETABLE FIBER-E;

This invention relates to a new or improved machlne for use in scouring either Wool and fibers,

other animal fibers or vegetable and for washing or cleaning yarns,

'5 textile fabrics or the like, and has for its primary objects reducing the time and number of vats at present required to effectually scour the fiber or cleanse fabrics or the like,

thereby saving floor space, power and labour and at the same time produce,

a better product, i. e. without stretchfibers, ing, strin in the case of ging or matting, than is posslbie with existing scouring machines.

The present invention comprises a vat or suitable c the fibers them in a ontainer having means for feeding into one end thereof and deliver scoured condltion at the other end,

means for subjecting the fibers preferably on entry to pressure jets or sprays of scouring solution or fluid, said jets or sprays being so arranged as to facilitate the breaking up or separation of the mass of fibers, and means for subjecting the fibers to an intermittent pressing or squeezlng action during their I travel through the scouring solution in the container, said means preferably consisting in passing ers and a the fibers between pressure rolltravelling belt or between the sur faces of a pair of travelling belts pressed to ether or an equivalent arrangement.

This in vention will be now more particularly described making reference to the accompanyi Figs. 1

A vat or container 41 is provided at its one end with wool or fibers into the machine.

adapted to engage and evenly feedthe wool or fibers down an inclined plane or chute a situate at the forward end of the vat a. A tube 0 provided with jets or nozzles is carried within the vat a near the chute a This tube is in communication with a supply of scouring liquid which is delivered to the jets or nozzles under considerable pressure. The jets or nozzles are so arranged as to cause the liquid issuing therefrom to impinge on and cause motion in the mass of fibers moving down the chute a thus tending to break up or separate the fibers one from the other and rid themin the case of wool from the bulk of suint, sand and other impurities. The jets of solu tion or fiuid tend to separate out the scouring solution and cause precipitation of the sand and other impurities, at the same time allowing the lighter matter, such as suint, to float to the top of the liquid. The vat a is provided with a perforated false bottom a and the sides and bottom a are preferably sloped as shown to form sumps into which the heavy impurities tend to settle and which may be emptied by means of valved outlets a Above and partly within the vat a and for the greater part of its length is mounted an endless belt (Z passing over drums (Z (Z one or both of which may be driven from any convenient source of power. The axle of the drum (Z is preferably driven by a belt in passing round a pulley m on said axle. The lower part of the belt d is arranged below the normal level g of the scouring solution in the vat a. The scouring solution may be caused to circulate or flow through the vat and may be drawn off through a strainer out let M. The lower part of the belt cl is given an undulatory movement during its travel by passing over and under a plurality of transversely arranged spring pressed rollers or drums e and rollers f. The said rollers exert a squeezing action on the fibers passing between the under surface of the lower part of the belt (Z and the peripheries of the rollers e. The bearings for the axles of the rollers e are preferably pressed upwardly by means of compression springs, as shown more particularly in Fig. 2. forated as shown more particularly in Fig. 2.

The belt (Z is preferably per- Between the rollers e are carried shaped trays g which are preferably perforated. The rear end of each tray 9 is at its sides slotted to fit over the axles of the rollers 6 so as to be free to rock thereon and the forward edge of the tray rests on the periphery of the roller immediately in front of it to act as a scraper.

The fibers on entering the solution are first acted upon by the jets issuing from the pipe- 0 which also cause the fibers-a-lso helped by the flow of the liquid through the vat-to move over the first roller 6 into contact with the under side of the belt (Z. The fibers are then carried along through the vat between the belt and the rollers being alternately squeezed and compressed and allowed to expand and absorb fresh liquor in each of the trays g.

After the fibers have passed to the outgoing end of the machine, they are automatically carried. to the rinsing or swilling vat 72 by any suitable form of conveyor. A convenient construction is that shown wherein an endless belt 71 passes over the last spring pressed roller 0, pulleys 2' above the surface of the liquids in both the vats a and 71/ and drum 2' the eriphery of which is or may be below the suri zice of the water or rinsing solution in the vat 71 The belt i is in contact with the belt (Z as it passes over the drum (Z and the fibers are prevented from riding round with the main belt (Z by 'means of jets 0 of liquid or air under pressure or by suitably placed scrapers. The fibers are then carried by the belt '2', being guided thereon by guides 71 beneath a spring pressed drum i which serves to express the major quantity of scouring solution from the fibers which are then deposited into the swillingliquid in the vat it.

Any fibers adhering to the belt 2' as it passes upward over the drum are removed by jets c of fluid under pressure. Other jets c of fluid under pressure tend to carry the fibers on to an endless belt 7:, which is carried by pulley 73 7a", is, W, k and 70 so that the fibers are conveyed through the solution in the vat h. Above the pulley 70 70 are arranged spring pressed rollers Z Z in order to squeeze the washing solution from the fibers in their upward passage out of the vat.

The partially dried fibers are then blown from off the surface of the belt is by air jets m into a container a.

The sides of the vat a (see Fig. 2) may be provided witlrgi'itters or troughso for the purpose of draining ofi the suint or wool fat that floats on top of the scouring solution. For this purpose, the gutters o are provided with perforations 0 near the level 3 of the liquid in the vat a. The suint is removed from the gutters 0 by outlet pipes 0 In the modification shown in Figs. 3 and 4, a pair of belts (Z, d, are used in place of a single belt at the fibers passing between said belts d, (Z either one or both of which may be perforated. In such case, the upper rollers f are preferably spring pressed downwardly on to supporting rollers 6 The belts between the pairs of rollers f and 6 may be opened out by means of stream lined shaped guide plates 7) arranged at the sides of and between the belts, their function being to guide and close the fibers together before the latter pass to thenext pairof rollers.

In the further modification shown in Fig. 5, a chain or linked belt 1' is arranged above and driven at the same speed as the main belt (1 which is supported by'rollers 6 The belt 7' carries a plurality of presser plates a hinged at s to saidv belt, which plates are provided with: ca'm or spring shaped upper parts adapted to contact with stationary rollers t as the belts are traversed.

It will be appreciated that the fibers, carried on the surface of the belt (,l, which is preferably perforated, are alternately compressed by the plates 5' against the surface of the belt (Z.
