Fixed on said the machine, which serve to support in dedriving shaft 11 is a pulley orother transsired. associated relation the severaloperamission element 14, and fixed on said shaft and journaled in bearing devices 6 is a similar pulley or transmission element 15. A transmission belt or the like 16 running over the said ulleys or elements 14 and 15 serve to rotate t e disintegrating or teasing element at the desired high speed.

Located intermediate the inner or rear end of said apron or conveyor 4 and said disintegrating or teasing element is a mechanism for feeding to the latter the scrap or other material to be operated upon. This mechanism comprises a pair of transversely opposite longitudinally adjustable bearing housings 17 arranged upon said side frames 1, in which is journaled a transverse feed roller 18 located adjacent to the inner or rear end of said apron or conveyor 4. Journaled in and extending between said bearing housin s 17, intermediatesaid feed roller 18 and said disintegrating or teasing element is a rip ping roller 19 of smaller diameter, and located very close to the periphery of said disintegratin or teasing .element. Said gripping-r01 er 19 is provided with a gripping surface 20 comprised of a plurality of gripping points or projections, andsaid gripping sur ace may be variously produced Y nurling, milling or otherwise roughenlng the said gripping roller. The reference character 21 lndicates a vertically movable or ieldable bearing guided in ways or guitlies 22 provided in each housing 17 said bearings 21 being normally subjected to the downward thrusting pressure of springs 23. Journaled to extend between said bearings 21 is an idler feed roller 24, disposed above and engaging the upper side of said feed roller 18, and likewise journaled to extend between said bearings 21 is an idler gripping roller 25, disposed above and engaging the upper side of said gripping roller 19. If desired, the surfaces of said feed rollers 18 and 24, and of said idler gripping roller 25, may be covered with asleeve or tread 26 of resilient material such as soft rubber or other suitable material.

As an illustration of one arrangement of transmission means for driving said apron or conveyor 4, said feed roller 18, and said gripping roller 19, I have shown in Figure 1 a pair of longitudinally spaced transverse shafts 27 and 28 extending between said side frames 1. Mounted on said shaft 27 is a conepulley 29, and on said shaft 28 an oppositely directed cone-pulley 30. Running over said cone- pulleys 29 and 30 isa transmission belt 31 subject to the control of a belt-shifter 32, whereby the belt may be shifted transversely on the oppositely tapered surfaces of said .cone pulleys to vary the speed of power transmission through said elements. Fixed on'said driving shaft 11 isa worm drive 33,

34 supported in connection with a side frame 1, 1s a vertical shaft 35 having at its up er end a worm gear 36 operatively engaged y said worm gear 38 fixe at its lower end erative y engaged'with a on said shaft 27 whereby said variable speed mechanism above de-' scribed is initially driven at a reduced speed from said driving shaft 11. Said feed roller 18 is driven by a belt 39, from a pulley '40 fixed on said shaft 28. Said apron 4 is driven by belt drive 41 or its equivalent from said feed roller, while said gripping roller 19 is likewise driven by a belt drive 42 or its equivalent from said feed roller.

Located immediately below the above described feeding and ripping devices is an adjustable ieldable evice for holding the material su ject to the operation of the disintegrating or teas'ingelement. This device comprises a transverse presser plate 43 provided with a curved or concaved face 44 concentric with the adjacent circumferential worm drive 33, and havin a worm drive 37 0 T surface of said disintegrating or teasing element. Rigidly connected with said presser plate 43, preferably adjacent to its ends, are forwardly extending supporting rods 45. The reference character 46 indicates the front wall of a bottom plate 47 which extends downwardly and rearwardly beneath the disintegrating or teasing element, and which is suitably secured to and between the side frames 1 of the machine. Said front Wall 46 of said bottom plate 47 is provided with guideway openings 48 through which said supporting rods 45 slidably extend. Connected with said side frames 1 are supporting brackets 49 provided with guideway openings 50 which slidably support the free ends of said supporting rods 45. The free ends of said supporting rods 45 are screwthreaded to receive an adjustable stop-nut 51, which may be locked in desired adjusted position by a lock-nut 52. Arranged around each su porting rod 45 intermediate the back of sai resser plate 43 and said front wall 46 of the bottom plate 47 is a compression spring 53 which exerts a forwardly moving pressure u on said presser plate to hold the same yie dingly presented to the surface of said disintegrating or teasin element, and normally spaced from the latter at a suitable-distance as governed by the adjustment of the stop nuts 51. The arrangement and mounting of said presser plate and its supporting rods is such that the same bears a radial relation to the center or axis .ing a fac'e'of short metallic One end of. said covering or sleeve 54 is suitably secured to the back of said presser plate, while the other end is secured to. the front wall 46 of the bottom plate 47. The upper edge of said presser plate may be provided with the longitudinally extending upwardly projecting flexible lip' member 55, which prevents the material from escaping outwardl between the to of the presser plate and the gripping rol er 19, and which guides the material downwardly to extend across the face 44 of said presser plate 43.

Extending transversely beneath said disintegrating or teasing element is a transverse drnm 56 provided with a surface face comprised of short metallic bristles 57. The said drum 56 is adjusted relative to the under circumference or face of the disintegrat ing or teasing element, so that the metallic bristles of the former will intermesh, in passing, with the bristles of the latter whereby the latter are cleaned, and any fibers, threads or strings adhering thereto will be removed therefrom. A similar drum 58 havbristles 5 9 is also provided, and so supported in adjusted relation to the under surface of the disintegrating or teasing element as'to cause its bristles 59 to likewise'mesh, in passing, with the bristles of the disintegrating or teasing. element, for the same purpose. latter drum 58 is. spaced rearwardly from said drum 56. Arranged to extend between said drums 56 and 58, is a brush roller 60 having a surface of long metallic bristles 61. The bristles 61 of said brush roller 60 intermesh, in passing, respectively with the bristles of the drums 56 and 58, clean the same by removing therefrom any material or fiber adhering thereto. For proper operative effect the respective drums 56 and 58 are rotated at comparatively slow speed, while the disintegrating r teasing element rotates at very high speed, onsequently not only will the fibers of teased material be further brushed out as they pass. between said drums and the disintegrating or teasing elements, but, due to the drag of the former upon the latter, said fibers will be removed from the disintegrating or teasing element for discharge from the machine. The brush roller 60 is rotated at a higher. s eed than are the drums 56 and 58 so that its bristles will readily remove adhering material from the latter. Said brush roller 60 is rotated by a driving belt 62 from apulley 63 on said driving shaft 11, while said drums 56 and 58 are respectively driven by driving belts 64 and 65 from said brush roller 60, although it will be understood that any other suitable arrangement or type of transmission means may be employed.

The disintegrated and linted material, when freed from the disintegrating or teasing element passes outwardly between suit- The and serve to ably driven batting rollers 66 and 67, whence the hat of disintegrated material may be fed away from the machine by the discharge conveyor or endless belt 68, all of which is common practice. In operation, the textile scrap or other material to be operated upon, is fed forward by the belt 4 to the feed rollers 18 and 24-, between'which the same passes, to be fed thereby between the gripp ng rollers 19 and 25. The gripping roller 19 is provided with a gripping surface 20 which cooperates with the idler gripping roller to firmly grip the material while slowly feeding the same to the action of the teasing bristles 10 of the rapidly rotated disintegrating orteasing element or drum, so that immediately the scrap or material issues from between the gripping rollers, the teasing bristles begin to brush the same out-into the desired long staple lint. As this brushing out of the scrap or material proceeds, the same is carried downwardly across the face of the presser plate 43, which is adjusted relative to the ends of the'teasing bristles 10. so as to hold the material subject to the whipping and teasing action of said teasing bristles. Since, however, said presser late is yieldingly presented or backed, i the material crowds or bunches up, the plate moves away so as to relieve the resistance offered by the scrap or material to the teasing bristles 10, whereby the latter continues a comparatively gentle teasing or brushing out opera-- tion upon the fibers, rather than a tearing, ripping or disrupting action tending to break the long staple desired in the fibers of the finished lint. The presser plate being thus yieldable, and the teasing bristles 10 being of such length as to possess a resilient or springy quality, it follows that the united action of the gripping rollers, and teasing bristles 10, results in a rapid and yet comparatively gentle disintegration of the material treated, so that a lint of long staple fiber is produced and finally delivered in a bat from the machine. The yieldable presser plate presser plate provides the proper backing,

for the material while subjected to the action of the teasing bristles 10, so that the said material is not too strongly pressed toward said bristles 10, yet is nevertheless so presented and held as not to escape the re quired brushing out or teasing action necessary to the best results.
