REVOLVING-TOP FLAT CAEDI'NG MACHINE.

Application filed August 3, 1925. Serialv 130. 47,959.

This invention relates to revolving top flat carding machines. In the usual construction of a flat carding machine, a sliver of cotton is impressed forwardly at the feeding end of the machine by a feed roll, from which the cotton is taken by a cylinder designated as a licker-in, revolving in the opposite direction to the feed roll while a carding cylinder picks up the sliver at the point on the licker-in which is substantially diametrically opposite the feed roll. The sliver of cotton is carded on the cylinder and carried between revolving flats where it is treated at the end of the flats by a stripper, the sliver then being removed by a doffer in the usual manner. The licker-in and feed roll co-operate to remove foreign particles through the co-operation of a roller having comparatively small dimensions.

It is an object of the present invention to provide slots in the housing or cover plate of a fiat carding machine upon opposite sides of the licker-in, to permit motes and short lint to be removed by knives, adjacent the slots and by means of an air blast which forces the motes and short lint from the sliver through said slots asthe sliver is carried along by the carding cylinder adjacent the licker-in and at points where the lickerin is in close contact with the said feed roll, adiusta-bly mounted rollers being disposed adjacent the slots and suitably covered for picking upthe short lint and the foreign matter discharged through the slots.

Another object of the invention is the provision of a slot formed at the V-shaped juncture of the licker-in cover and the back knife plate, the edge of the cover at this pointbeing cut away to provide an elongated transverse slot and a pair of knives having a shearing action over the sliver on the carding cylinder andthe film of lint carried by the licker-inr a draft of air which has'been produced by the revolving cylinder being driven through the slot to cause. the loose ends of the short lint to be carried through the slot which have been removed by the knives at the opposite edges of the said slot.

A further object of the invention is the provision of slots, knives and rollers for removing short lint and foreign matter from the carding engine at points along the card ing engine adjacent the feed roll, and also at points adjacent the dofter, so that a particularly clean sliver is provided at the discharge end of the carding engine which will be equivalent in quality to that produced by the ordinary double carding process.

This invention will be best understood from a consideration of the following detailed description, in view of the accompanying drawing forming a part of the specification: nevertheless it is to be understood that the invention is not confined to the disclosure, being susceptible of such changes and modifications which shall define no material departure from the salient features of the invention as expressed in the appended claims.

In the drawings Figure 1 is a view in perspective of the feeding end of a flat carding machine, showing my invention applied thereto Figure 2 is a longitudinal vertical section of a flat carding machine showing my invention in operative position,

Figure 25 is a side view in elevation of a carding machine constructed according to the principles of my invention.

Referring to the drawings, in the usual flat carding engine, a carding cylinder 10 forming the carding device proper has a plurality of teeth 11 on its surface which are adapted to be drawn through the sliver for laying the lint in straight lines and for removing motes. The sliver is fed to the teeth 11 of the cylinder 10 by a licker-in 12, at a point where the licker-in and cylinder are in operative relationship with each other. The cover 14 for the licker-in and the curved front knife plate are normally in close contact above the licker-in 12 and cylinder 10 providing a V-shaped formation as shown at 16. A knife 17 on the lower edge of a stripping plate 15 removes motes and short lint from the sliver which is carried around the cylinder 10. Revolving flats 18 are employed for the usual purpose. The usual feed roll 19 normally supplies the sliver to the licker-in at a point indicated by the numeral 20, the sliver being drawn from a roll of sliver 21.

In the present device an edge of the cover 14 at the V-shaped connection 16 is removed to provide a restricted slot 22 and an additional knife 23 on this edge of the cover. The co-operating knives 17 and 23 are adapted to :remove :motes and short lint from the sliver which are forced through the 'restricted slot 22 into engagement with a revo'lv ing roller 25 which has a linen-cover to provide sufiicient frictional engagement with the lint coming from the slot 22 to collect and roll the lint upon the face oft-he roller.

t will be appreciated that the carding cylinder creates sullicient air draft to force the lint and motes through the opening 22 during the operation of the engine.

The roller is provided with projecting spindles 26 and 27 which are received within U-shaped bearings 28. Each hearing is formed by providing" upstandingears at one end of a plate 29. The plates are secured by means of bolts 30 to the frame of the engine. Each-o1. the plates 29 is provided with a .slot 31 whereby the -.U-shaped journal 28 maybe adjusted as desired. The spindle .26 is extended and .isadapted to be received within a slot 32 formed at one end oi? .a bearing plate 33. A gear 3 l is rigidly connected with the spindle 26 and :meshes with a 1ge-ar 35. This gear in turn meshes witha gear 36. The gear 36 is driven by a .r ear '37 mounted on a shaft 38 which normally forms for driving element of the carding engine. The bearing 33 .is provided with a perforation39 adapted to be received by the shaft 38 and intermediate its ends .andnt its lower edge an extension 40 .is provided .hav ing a slot 41 extending from said extension and through a portion .of the body of the ,plate 33. A set-screw d2 passes through the slot and is supported by the engine frame so that the plate may be adjusted in predetermined positions when desired, by oscililating said plate on its pivotal point with the shaft 38.

Gears

35 and 36 are carried respectivelyyby stub shafts l3 and id mounted on the bearing plate 33.

The cover plate 1% of the l-icker-in is cut away to provide-arestricted transverse slot s5 and a :lrnite-edge d6. T hislrnife edge and consequently the slot adapted to remove what motes and short lint have not been removed by the knife edges 17 and 23 defining the slot 22. The lint is collected on a roller 47 located above the slot 45 and is provided with spindles d8 mounted in Ll-shaped bean .ings .9. The bearings 49 are substantially :a pair of spaced ears connected to a base .lint passing through the slot4'5 is collected on the surface of the roller 47 which is "I ..-rewise covered wlth linen in order to provide the slot 45 and aid 'thedoor being below a plate 73.

suficient frictional surface to collect the lint. As the diameter of the roll which being constantly covered by the lint, increases, the

lilshafi ed bearin 's e l/ ermit the spindles 48 lint which are ordinarily carded to produce a refined sliver. The fact that the roller 47 is movable in theslotted bearing d9 permits the roller to drop when free of lint adjacent l in preventing the dis charge of lint from theslot and thus act as a choke.

At the back end of the engine and below the pn ley 54. which is associated with an end of the revolving flats 18, I providea pair of slots and 56st oppositesides of a door A knife edge 58 is provided at the "lower end of the hack knife plate 59, which is adapted "to further remove short lint and motes from the sliver. The slot 56 is provided to Dermit lint -r. motes to be discharged which :is collected upon a roller 60 which is likewise covered with linen to provide sufficient trictional surface for the collection of the lint as it is dischar ed through the restricted slot 'The rollers are provided wit-l a spindle 61 mounted in Ushaped brackets '62,

which are similar in construction to the from the sliver.

Gear 34 being in mesh with the 'gear .35 is driven by said gear and since the diameter of the roller '25 is increased as it takes up and lint, the 'lJ-shaped bearings 28 permit the spindles 26 and 27 to rise in the bearings, and also in the slot '32 in the plate 33, while maintainingthe gear 34 in mesh with the gear 35. It will be appreciated that while ll-shaped bearings permit movement of rollers to accommodate the increased diameter of said rollers, due to the addition of lint, that it will be necessary to construct .these hearings in such a manner that the rollers may be sufi'iciently elevated where it is intended that the lint be permitted to accumulate to increase the size of the rollers considerably so that the gears on the ends of the shafts .Wlll be maintained in mesh with the respective driving err.

The rollers 25, l7 andfGO are closely associated with their respective transverse slots in order to choke the slots and prevent too great a quantity of air being forced through the same by the air draft produced by the revolving carding cylinder 110. I
