Definitions

  • the object of the invention is an improved. machine of the type aforesaid so as to obtain a higher degree of opening and cleaning and dust removal. 7
  • a machine for opening and cleaning fibrous materials comprises a hopper and casing containing a sloped spiked lattice adapted to carry the fibrous material upward and below an evener roller and thence to a heater in another part of the casing, with stripper means for and adjacent to said evener roller and suction means for extracting dust from the upper part of the feed sideof the hopper characterised in that the stripper means for the evener roller consists of a combined rotary suc-. tion cage and stripper whereby dust liberated from the fibrous material by the combined ac-.
  • tion of the evener roller and its stripper may be more effectively removed by removing it at the region of such liberation and without loss of useful fibre.
  • the machine aforesaid may be further characterised in that the combined rotary suction 4 5.
  • cage and stripper comprises a rotary suction cage, flaps on said cage adapted to act as strippers for the evener roller without holding the stripped material and a damper Within the suction cage adapted to confine the suction to the portion of 0 the cage periphery immediately facing the evener roller.
  • a machine for opening and cleaning fibrous materials comprises a casing, a beater housed 5 therein and working against dirt bars, and to,
  • beater the material is fed by a spiked lat-f tice characterised in that the casing is shaped: without a stripper edge so that only a portion of the material is delivered by the beater for car--' 'rying'forward, and so as to provide a space of sub-' stantial volume above the beater into which the remainder of the material is projected by the beater whereby at least some of it returns to the heater for further beating, means being provided such'as a partition to prevent such projected material from being thrown into the region above the spiked lattice.
  • the machine last mentioned may be further 5 characterised in that a plurality of beaters is pro-- vided arranged in series each without a stripping edge and so that each beater except the last of the series delivers some of the material forward to the adjacent succeeding beater and projects the remainder of the material into the space above the beaters from which it may return for further beating; or further characterised by'a suction cage arranged to receive that portion of the material from the beater or last heater to be carried forward; or further characterised by at least one suction cage in the space above the heater or beaters for the extraction of dust lib-f erated by the action ofthe beater or beaters pro'-' jecting the material into the said space.
  • v ig. 1 illustrates diagrammatically a machin for opening and cleaning fibrous material accord, ing to this invention
  • Fig- 2 illustrates diagrammatically a modifica tion of the machine shown in Fig. 1.
  • the rearward portion I of the machin constitutes a hopper in which the horizontal lattice 2 feeds the cotton towards a spiked lattice 3.
  • An evener roller 4, with spikes 4 . is located above the spiked lattice 3 and allows a certain proportion of the cotton carried upwards by the lattice to pass forwards while the rest is projected back into the binl
  • a stripper is provided for the evener roller.
  • a combined high speed suction cage and stripper 5 is provided in place of such a stripper.
  • the suction cage is provided on; its outer peripherywith leather flaps 5 which,
  • the flaps 5 may be of any other suitable material instead of leather.
  • the cover fits closely to the beater and is provided with a strip ping to ensure that practically all the cotton acted on by the beater is stripped from it and delivered to such means of furthrconvey ante may be adopted.
  • a second beater 811s provided withdujt the intervention r a sthtpihg'jede j er the heater and in series with the first, beater, w h the result that cotton delivered by the ust -beater is only in part acted upon hhmeftten by the second beater, the remainderbeing p jected upward'sinto a region 9 provided under a cover I w ch is raisedasubstan-ti al dista'hte atleast equal to the diameter of the beater, as shownin' the drawings above the heaters and has no stripn..; ed e f e second be fi :r that $1 is proyided with spikes 8 and
  • an upwardly e ending partition [3 is provided within thecasi that substantially divides the s 'ame intoa ng compartment and a hopper compartm nt said partition having an ,apertur l3 af-f ng limited intercommunication between said part'ments, the upper section jof the partition the aperture [3 being straight and sepam the region 9 from the regioii b'elow the bar ch 12 of the cover in which the vrir' roller e sect on ofithe partition. l3va'riab1' by such rn'ea' s is located while allowing room for the passage of the cotton to the beater l.
  • the upper straight section of the partition occupies, relative to the evener roller a position roughly the same as that occupied in known forms? of hopper feeders by a" vertical portion of the outer cover.
  • a machine for opening and cleaning fibrous" material's comprising a casing, a p'a'r'tition'jd'is;
  • said beating compartment having an upper wall at all points spaced away from the beater a distance at least equal to the diameter of said beater thereby to provide a substantial space above the beater, at least one additional beater being disposed in the beating compartment in series with said first beater whereby each beater except the last of the series delivers some of the material forward to the adjacent succeeding beater and projects the remainder of the material into the space above the beaters from which some of it returns to the said beaters for further beating, a suction cage being disposed in the beating compartment in position to receive material from the last beater for collection and delivery of the material from the beating compartment.
  • said beating compartment having an upper wall at all points spaced away from the periphery of the beater a distance at least equal to the diameter of the said beater thereby to provide a substantial space above the beater, a high speed suction cage being disposed in the space above the beater in position to extract dust from the material projected into said space by the beater.
  • said beating compartment having an upper wall at all points spaced away from the beater a distance at least aperture in the partition, an evener roller mountr ed for rotation in the hopper compartment above the upper end of the lattice in position to remove surplus material from the lattice thereby to determine the thickness of material carried forward on the lattice, a rotary stripper disposed in said casing above the lattice and adjacent said evener roller in position to return the said surplus material to the said lattice, and a rotatable beater and dirt bars cooperating therewith disposed in the beating compartment in position to receive material from the spiked lattice through the said aperture, said beating compartment having an upper wall spaced away at all points from the periphery of the beater a distance at least equal to the radius of the said beater thereby to provide a substantial space above the beater, and a high speed suction cage disposed in the said space of the beating compartment above the beater in position to extract dust liberated by the actio'n
