I 0 all whom it may concern Be it known. that 1, WILLIAM Burns, subject of the King of Great Britain, residing in Bradford, in the county of York and Kingdom of England, have invented certain new and useful. Improvements in Textile Spinning, Drawing, Slubbing, Roving, and the like Machines, of which the following is specification.

The present invention relates to improvements in textile spinning, drawing, slubbing, roving and the like mach nes, and is applicable to any machine normally treating textile fibre lying between the carding or opening machine and the finishing spinning device.

According to the present invention a fibre is taken up from a pair oi feeding or draft or the like rollers by means of an air stream and is guided by it axially down passage to the place where it is to be spun or otherwise operated upon.

Means may be provided to prevent the escape of the conducting stream oi? air at the place where the fibre sliver or end is picked up. This means may comprise stationary packed surface operating with the rotating feeding surfaces or it can comprise further baffling streams of pressure air preventing leakage at these points.

The present invention is more particiilarly described with reference to the accompany ing diagrammatic drawings, in which Figure 1 is a general arrangement of the invention as applied to a spinning frame.

Figure 2 is a detail of one form of construction in sectional elevation.

Figure 3 is a corresponding view of a modification.

Figure 4 is a corresponding plan view of Figure 5 is a sectional. elevation of a "fun ther modification.

Figure 6 is corresponding plan view of Fig. 5. I I

Figure 7 is a diagrammatic view oi .111 other arrangement.

A. pair of drawing rolls 1, 2, of any de sired known construction have a guide tube 3, arranged below them which leads to the spinning place. Air is led into a chamber 1, formed in the intermediate space between the tube 3, and the two rolls 1, 2, by means of an inlet pipe 5. This chamber or space 4:. is packed by means of leather glands such as 6.

It will consequently be seen. that the sliver or yarn passing axially down between the two rolls will be taken up by the air stream and must of necessity be conducted down the air tube 3. Consequently a sure feeding of the sliver is obtained even after breakage has occurred without any mechanical. or hand operation.

The arrangement shown in Fig. 2, shows the rolls driven by a leather or like band 7 but this may be of any desired form. A plate 8, which may be faced with leather, rubber or the like material closes the back and front of the chamber 4, against leakage. Further the rolls 1, 2, may be slatted and air led in through their centres radially outwards the sole outlet being through the tube 3.

In the construction shown in Figs. 3 and 4, the air chamber is packed by means of a pair of gland members 9, 10, which may be spring controlled and air is led to the space 11, between them from an air trunk 12, which may be in communication with the inlet pipe 18, with a view to preventing leakage at this place. Further air is led in through the hollow spindles 141, of the drawing rolls to pass through passages 15, therein to grooves or spaces 16, arranged between the sides of the drawing rolls and the side walls 17, similarly for packing purposes, that is to say to present bafiling or packing air pressure pre venting leakage at this place of: the main current from the conduit 13. (inc or both of the rolls may be faced with leather or other material such as 18.

A further form of construction is shown with reference to Figs. 5 and 6 where air pressure from conduits 19 is passed to the packing space 20 and also passes to side passages 21, leading into channels or groovings 22, formed in the sides of the drawing rolls, a labyrinth packing so being formed against leakage of the air stream operating tl e displacement of the sliver or fibre.

The construction as applied to cap spinning arrangements of ordinary form is shown with reference to Fig. 7, in which the drawing rolls 2S, feed sliver 24;, axially down a rotating tube 25, driven by a band 26, or any desired means. This tube 25, extends from a chamber 27, formed as above described and fed with pressure air from a main 28. The air therefore can only escape down the rotating tube 25, and takes the sliver or fibre with it irrespective of its continuity. Spinning is efiected by centrifugal force as'the sliver passes under the lower edge 29 of the spinning; cap 30- to-be spun I number of spinning'devices in series, that isto say, an air stream passing "from a main trunk'or conduit to the chamber between a pair oi drawing rolls 34L, le'adst'he fibre axially down the tube35, which fibre is then spun at this place whilst theair stream exhausts into an enclosure-36, allowlng it to pass into the condult 37, ieedingagainthe next pair 01'? drawing" rolls '38.

' In the particular arrangement shown the air stream passes from pairs of drawing rolls through pairsxof' axial passages but of course three or more may be arranged in parallel as desired and can beconnect'ed'in- 1n the presence of two subscrlblng witnesses.

series.

Any desired means may be- -used= for 0btaining a movingair' stream that isto say that the air stream will exist by reason of a difi'erencein pressure between two terminal points, this difference being' obtain ed by difference in pressure either above or below atmospheric pressure as desired.

I declare that what I claim is 1. V A textile spinning machine comprising drawing rollers, a guide tube having its axis intersecting the line of contact of said rollers, means to spin the fibre at the end of said guide tube,- means to convey the textile sliver from said drawing rollers through topack the sides of said drawing rollers to prevent air leakage.

" 2. A;- textile spinning machine comprising drawing rollersgan air tight chamber'at the delivery side ofsaid rollers, an outlettube leading from said chamber having its axis intersecting the line of' contact 0t said rollers, spinning means at the end of said tube and means to establish differences in pressure between-"said chamber andthe outlet end oil the tube.

In witness whereof; I have hereunto signed my name this 19 day'of Deon-1921,
