*rnn s ra rns ra rn @FFTUT PROCESS OF MANUFACTURING YARN.

To all whom it may concern Be'it known that l, JAMES THAME,a subject of the King of Great Britain and Ireland, residing at London, England, have invented new and useful Improvements in Processes of Manufacturing Yarn, of which the following is a specification. This invention relates to improvements in the manufacture of yarn from fibrous material, c. g..'raw waste fibers such as from banana fiber, megass and the like or from waste from manufactured products made from fibrous materials such as cotton, jute, hemp, manilla, sulfite wood,-ramie and the like which may be partially or wholly obtained from such waste products as old rags, waste paper, rope, yarn, sacln'ng and the'like or from similar substances possessing or containing fibers or from which fibers of moderate length can be obtained.

' Referring to the drawings which form part of this specification, Figure l is a side elevation of a breaking engine as illustrative of a type whichmay be employed in my process. Fig. 1 is a plan of Fig. 1. Fig. 2 is a sectional elevation of the tank containing the oscillating trough. Fig. 2 is a plan of Fig. 2. Fig. 8 diagrammatically illustrates the various devices employed to convert the sliver taken from the trough shown in Fig. 2 into yarn. Fig. 4 is a plan of part of Fig. 3. Fig. 5 is a side elevation of one pair of the drawing rolls.

The material to be dealt with must be first cleaned in known manner by separating the dirt therefrom in the presence of water and then treated mechanically as hereinafter described by any suitable device producing a breaking down or separating action in such a manner as to insure that the fibers are separated one from the other, retaining as long a length as possible say from gto 2 inches, the breaking up of the fibers to the extent of forming a pulp product being carefully avoided. The fibers are drawn out mechanically for example by the action of the apparatus shown in Fig. 1 comprising a rotary roll a fitted with plates 7) working on a fixed bed plate or equivalently a box 0 containing plates similar to the plates 6 or blocks may be used in place of the plates, the roll a revolving in a tank or container 1 partially filled with water so as to draw the fibers out rather than to beat them into a pulp such as is produced for paper making.

A drum oi having spikes If on its periphery can also be rotatably mounted in the tank, said spikes co acting with a series of spikes c mounted in the block al to produce a combing effect in the fibers. A convenient form of apparatus for this purpose is an ordinary beatingengine adjusted so as not to break down the fibers beyond the point already indicated, the cleaning of the mate rial being effected during the breaking down process by a rotary drum 6 having a periphery f of wire mesh and a series ofinternal scoops g axially inclined to cause delivery in an axial direction. The drum 0 is partially submerged in the liquid in the beating engine so that the dirt which floats as a scum on the surface of the liquid will pass through the wire mesh periphery f, be collected by the scoops g and delivered laterally into the chute it while the fiber is prevented by the wire mesh periphery 7 from being carried away at the same time. The mixture of fiber and water so obtained is then run off into a tank j where it is kept agitated by paddles 7a or other known means to keep the fibers in a state of suspension in the water. The paddles areoperated by a crank mechanismZ. From this tank 7' the fibrous'mixture is run through an adjustable orifice m as a stream into an oscillating trough n with walls of wire mesh or partly of plain material and partly of wire mesh the oscillation or side movement of such wire mesh trough being obtained by cams, eccentrics 0 or any other suitable device, as shown in Fig. 2.

The wire mesh trough n is made to oscillate in a tank 10 but is arranged not to touch the bottom of same and the stream of water and fiber is fed down the wire mesh trough n of such a depth depending on the depth of submergence of the wire mesh trough a in the liquid in the tank 79 that the layer of fibrous material is submerged in same for the greater part of the length of the trough n which latter is slightly inclined so that the fibers are above the water level at the delivery end of the trough.

I may form the wire mesh trough n, of a fiexible material as an endless band as shown in Fig. 2 and give it a direction of move ment in the direction of fibers by supporting it on and driving it by drums Q. I may also arrange water jets r to play on the stream of fiber and water to assist in directing the fibers. I find that when the fiber in the wet state is fed into the oscillating Wire trough n that owing to the action of the water in the outer tank they arrange themselves in a parallel formation in a direction longitudinally with the trough and automatically form themselves into a sliver or yarn. On

reaching the delivery end of the wire trough n the sliver or yarn is taken hold of by a pair of plain or felt coveredrollers in Fig. 2 the drum g and the roller 8 are provided and the sliver received on to a wire or felt band 25 shown in Fig. 3 which is made to travel at the same rate as the fibers in the trough n. The sliver or yarn is slightly squeezed or the wire or felt band may be passed over a vacuum box to extract the bulk of the contained moisture and in its condensed form the yarn or sliver is passed to two sets of drawing rollers u dried round a steam heated drum w then spun or twisted by a twisting machine '0 and finally taken around another steam heated drum 2 for final drying and reeled ready for weaving. As shown in Figs. 3, 4 and 5 one set of draW- ing rollers has the upper roller adapted to have an axial movement given to it by an eccentric m in addition to the rotary motion by the pulley 3 claim 1. A process for the manufacture of yarn consisting of beating of waste material in water, separating the extraneous material from the waste while still in water, picking the Waste material While still in Water, beating up the waste delivered from the picking, parallelizing the fibers of the waste by'transverse oscillation in Water, condensing the said fibers, drying and twisting the same into yarn, and finally drying the yarn for reeling. r

2. A'process for the manufacture of yarn consisting'of beating of waste material in. Water, separating the extraneous materlal from the waste while still in water, picking the Waste material while still in Water, heating up the waste delivered from the picking, feedingthe fibers of the waste in a stream of water, parallelizing the fibers of the waste versely oscillating the said stream, the Water surrounding the-fibers having impartedto it a motion in the direction in which the said fibers are to be parallelized to feed the fiber along in said direction, condensing the said fibers, drying and twisting the same into yarn, and finally drying the yarn for reeling; H In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
