MACHINE FOR BLENDING WOOL Filed Feb. 4, 1945 Patent'ecl `uly 28, y1953 OFFICE Y MACHINE FOR BLENDING WOUL Jack Dunbar Townsend, VLowry Bay,
New Zealand y Application February 4, 1948, Serial No. 6,312
In New Zealand January 24, 1947 9 Claims.
The invention relates to machines for performing the operation of what is commonly re-l ferred to' as the blending of wool, for thepurpose pf enhancing the commercial value of same, and which consists in opening out the wool and ensuring the intimate mixing of the constituent fibres of portions of varying shades or colours so as to give the wool a more or less uniform appearance throughout, with portions thereof of less desirable appearance so distributed through the wool that the latter in bulk is of improved appearance.
Known machines provided for the aforesaid purpose comprise rotary drums with rows of teeth thereon, operating over grids, the Wool tov be dealt with being fed between Vfluted feed rollers from which the wool passes to the toothed drums and is acted upon solely by the teeth thereof while passing from the feed rollers, which are fixed as regards distance from the drums, and which give rise to the objection that all vwools of varying lengths of staple are not able to be successfully dealt with by the same'machine.
The object of the invention is to provide improvements in the aforesaid type of machine, so as to enable one machine to successfully deal with wools of varying lengths of staple, irrespective of whether the blending is to be performed (o1. isa-'96) by the opening out and intimate mixing of difl Y ferent portions of the same wool or of different vwools.
A wool blending machine provided with the improvements comprising the invention, incorporates one or a plurality of toothed drums, adapted to operate over grids and in conjunction with feed rollers, and is characterised by the provisions of means, capable of being adjusted towards or from the drum teeth in accordance with the length of staple ofthe wool under treatment, for the purpose of retarding` the Wool against the action of the drum teeth.
In one instance, the Wool retarding means can comprise feed rollers capable of being adjusted 'towards or from the drum teeth, and in another instance, said wool retarding means can comprise stationary teeth, capable of being adjusted towards or from the drum teeth.
The accompanying drawing illustrates the aD- plication of the improvements to a Wool blending Figure 2 is a plan View of same with th'ecovers i..
removed, while Figures 3 and 4 are detail views illustrating thev formr 4and arrangement of the drum teeth. and the stationary teeth, and
Figures 5 and 6 are detail views of the mechanismY for raising and lowering the grid frame inl order to obtain adjustment of the stationary teeth. Y
As illustrated, the machine comprises a main frame I having mounted thereon by means of cross shafts 2 Vand bearings 3, a primary drum 4 and a secondary drum 5, adapted to be rotated in the direction indicated by the arrows in Figure 1,1by belt drives applied to pulleys 6 on the shafts 2.
. Each drum 4 and 5 has secured to and spaced equi-distantly around its periphery, rows of teeth I shaped as illustrated in Figure 3,'the number of rows of teeth on drum 5 differing from the number of rows on the other drum, so as to insure more effective blending of the wool.
The drums 4 and 5 are finely balanced and are machined perfectly true at their peripheries, the teeth 1 on each and both drums being in perfect alignment through the length of the machine and beingv designed to avoid damaging the wool.
, Fluted feed rollers 8 disposed one aboveA the other are provided adjacent the primary drum 4 at the feed end of the machine, the bearings for the upper roller 8 being adjustable in the lsame housing 9 as the bearings for vthe lower roller 8, and being maintained in contact with thelatter by spring means in conventional manner, such arrangement and mounting of the feed rollers allowing for rise and fall of the upper roller 8 to suit the quantity of wool going through the rollers 3 to the drum 4.
The feed rollers are driven througha crossed belt reduction drive I0 from the shaft 2 ofthe primary drum 4, and reduction chain drives II, tothe shaft of the lower roller 8.
Wool to be processed by the machine, is delivered to the feed rollers 8, by an endless conveyor I2, made to pass around rollers I3, which with the housings 9 for the bearings of the feed rollers 8, are mounted on a secondary frame I4 slidable on the main frame I towards or from vthe primary drum 4. j Ihe endless conveyor I2 can be of any suitable form,` its front: roller I3 being driven through a chain drive I5 from the opposite end of the shaft of the lower feed roller 8 to which the drive I I is applied.`
The location of the front roller I3 of the con- 'veyor I2 as regards clearance from the feed rollers 8, to suit the type of conveyor I2 being used, is capable of adjustment by screw adjusting means at I6, While similar adjusting means can be provided at I1 to tension the conveyor I2 as required, while undue sagging of the upper side of the conveyor I2 can be prevented by means of a rigid spreader plate support.
The feed rollers Bare capable of being adjusted towards or from the toothed primary drum 4, to provide for the treatment of wools having staples of varying lengths, by the teeth T of the drum 4. while the wools are still gripped by ,and as they pass between the feed roller 8, by sliding the frame I4 on the main frame I, screw locking means I8 being provided between the frame Il and the frame I, to maintain the former in a selected position on the latter, and as the rollers I3 and housings 9 are al1 mounted on the frame I4, the relationship of the conveyor I2 to the feed rollers 8, and the tensioning of the conveyor I2, are not affected by alteration of the location of the rollers 8 in relation to the Adrum 4.
The provision of feed rollers 8 adjustable as aforesaid, enables a considerable range of wools of long and comparatively short staples to be suc.- cessfully dealt with, but where the wool staple `is so short that even with the feed rollers B adjustable as aforesaid, the desired treatment can not be effected, provision is made for the opening out and miXing of the wool portions or Wools, to be erformed between the teeth 'I .of the drums 4 and and other teeth I9 held stationary during the operation of the drums 4, 5.
As previously mentioned, the teeth 'I on th drums il, 5 are in rows thereon, and the stationary teeth I9 are also in rows, the latter being positioned and held, and the teeth I9 thereof so spaced, that the teeth 'I of the drums d, 5 pass between them, the spaces between the moving teeth 'i and the stationary teeth I9 being such that the wool is thoroughly dealt with to effect the blending without detriment thereto.
Provision is made for adjusting the stationary teeth towards or from the drums 4 .5 to suit different lengths of wool, or .to so position VSaid stationary teeth I9 that they will take no part in the operations-ras, for instance, where the wool is wholly dealt with by the teeth l on the drum 4, while gripped by the feed rollers 8..
One or more toothed rotary .drums can be employed, and there may be one or more rows of sta-.- tionary teeth I9 in relation to each drum, said last mentioned rows being mounted on a frame and spaced about the peripheries of the'drums 4,5.
The frame 26 is adjustable vertically in the frame i to bring the teeth I9 into the desired relationship with the teeth I of the drums 4, 5, or to cause the teeth IS to be lowered completely c-lear of the teeth 1. Vertical adjusting screws 2I held in brackets 22 on the frame I are operated through nuts 23 secured on brackets .24 ofthe frame 2e. The screws 2I are geared together ,by .bev-el gearing 25 and shafts 25 on both sides of :the frame I. All the screws 2| can be operated simultaneously from a single 4operating point von cross shaft 21vwhichis operably connected to each shaft 26 to raise or lower the frame 20, evenly.
.Grids comprising a grating made up of a plurality of parallel bars indicated at 30 areprovided on the frame 20 between the rows of teeth I9 and at the sides of the latter to conform to the contour of the drums, said grids 30 being of any suitable formation and being interchangeable as required, the provision of the grids allowing loose dirt and foreign matter removed from the Wool, to be disposed of, and so avoid Same nding its way later into the scouring liquor.
The machine can be provided with a conveyor for discharging blended wool from the machine, `and, with necessary casing, guards, control means and other parts essential for its operation.
