' brous constituent and forgetting rid of the'nonusable wood and skin or unwanted detached particles commonly styled shive.
The invention concerns an apparatusto whichthe flax straw or the like (if necessarypreviously treated) can be fed or delivered mechanically or otherwise, and which has some features in common with the well-known Crighton or-vertical opener used in the cotton trade.
The proposed apparatus differs from a Crighton opener in a number of respects, as for example, in that the beater and surrounding-grids or cage are not located in a closed outer casing, but in a. casing which can breathe inorderto allow the shive (which is comparatively light,
trash carried in cotton) to be carriedthrough the open work cage and deposited'in the-casing capable of breathing by the action of a generated air current. In order to assist in opening and cleaning the fiax straw, and to generate the air current, a revolving propeller or impeller isle.-
[ cated at or near the bottom of the beater; and; such impeller operates in a fluted dish or annularcurrent andalso to permit the flax straw massor the like to be delivered thereinto.
The surrounding grids or cage to the revolving 40 beater are not like the Crighton grids, but are so fashioned or of a character to suit the service, and different kinds of simple reticulated grids may be used, the same constituting an openwork cage-surrounding the revolving beater, the 45 upper rotating elements of the latter drawing in air and opened material from the top ofthe cage.
The outer casing surrounds the cage, the beater and the impeller, and is of such size or dimen- 50 sions as to produce an ample compartment to receive the trashand such casing is not, air tight or closedbuthas-pervious areas. From the top ofthe apparatus there may be an air trunk or tube or receiving outlet which can be coupled 55 toacage structureor any equivalent receiving,
as contrasted with the weight of'impuritiesand;
acting partly as a fan to-discharge the delivery or conveying apparatus, and whichmay. I
combine one or more pervious cage contrivancesin a housing with stripping, damping or other provision, and by which the cleaned, openedand collected fibrous material can be delivered into. any receptacle or other apparatus or to means to. carry or otherwise transport the deliveredfibre to theplace desired. Similar or suitable means may be providedfor feeding the fibrous materialv to the apparatus.

An apparatus for the purposes described and embodying the foregoing features will now be. described and explained with reference to the ac-. companying drawings, wherein Fig. 1- shows a sectional elevation of the clean-.-

Fig. 9a is a detail section of inclined bars of the grid shown in Fig. 9 and elsewhere.
Fig. 10 is an enlarged and broken view of the driven upright shaft, the beater and the striker arms.
There is used a housing compartment or cas ing a. This has movable or removable walls or panels 0, the panels being of a pervious nature, as for example canvas or openwork fabric panels can be used mounted in frame-work supports, the frame-work supports being secured by hinged catches (1. There is a fluted dish or annular trough hereafter referred to as a roughened trough b and this is shown as having ribs marked b see Figs. 1, 4, 7 and 8, such roughenedtrough I) having an inlet or feed slot 17 This roughened trough b is stationary and is supported a short distance from the floor of the casing a and air can obtain admission to the interior thereof through the open base. Within the roughened trough b is disposed an impeller (shown as consisting of inclined blades 0 fixed to inclined ribs c cast on the boss 0 the same being fixed to a rotatable shaft 0 the lower end of which is supported in a step bearing 0 This rotatable shaft 0 can be driven through a pulley c and also supports a revolvable beater d preferably of an inverted conical type the spaced discs of which are shown as carrying strikers d variously inclined or arranged. The vertical shaft 0 is driven at a high speed so that the impeller c and revolvable beater d are rotated at a high speed. The impeller 0 draws the flax straw or the like, and also air along the feed pipe e, via "the feed slot 17 into the roughened trough b', the impeller opening the flax straw by the action of the blades against the flutesor ribs b ofthe roughened trough b, throwing the opened fibre andthe shive upwards into the surrounding open-work cage g where the. beater d, operates.
The fibre is there further acted upon the bulk of the air induced by the impeller .is discharged outwards through the grids in the lower part of the open-work cage g which surrounds the beat:
er d, the air discharged therethrough carrying.
the shive (unwanted material) along with it so that same can be deposited in the casing a..
The cleaning and separation is effected by centrifugal and beating action in the presenceof a plentiful supply of circulating air. The comparatively light waste is thrown out and deposited in the casing a, as, duerto .the pervious panels a air can readily circulate and pass through the surrounding open-work cage structure marked as a whole 9 outwards and inwards, because the surrounding casing a is not sealedor closed as is a Crighton opener. Therefore air is freely circulated through the surrounding open-work cage g, because the casing a. can breathe and so the opening apparatus can function effectively to permit the throwing out and deposit of the shive within the casing a with pervious panels 0). F
The revolving beater d is so constructed an provided with strikers and the whole arrangement is such that it has a tendency to ensure an effective opening as also a fan or lifting action, and its upper revolving elements by exercising a fanlike action draw air through the upper part of the open-work cage g which air assists the forwarding of the cleaned and opened material to the outlet as at f.
The grid structure of the cage 9 may consist set of frames g spaced steel bars of narrow blade-like cross-section 9 may be mounted and these are inclined to the vertical producing upright gaps whilst the other alternate frames 9 may be fitted with woven wire grids 9 presenting rectangular or other apertures, the drawings showing square apertures. Through these gaps and apertures the shive is carried by the circulating air current generated by the impeller c and assisted by the beater d and this shive settles in the casing a and can be emptied out for example by opening the pervious frames or doors The Fig. 3 illustrates, by way of example only, an approved feed and delivery arrangement for use with the opening apparatus described. In this, the fibrous material to be treated is fed to trunk or pipe I and passes to a revolving cage or condenser 2 to the interior of which a fan 3 is coupled.
The material is removed from the cage 2 by a revolving ribbed stripper 4 and passes along the pipe e to the slot b in the roughened trough b. The delivery arrangement is similar, the opened fibrous material passing along the trunk or pipe 5 to a cage or condenser 6 with coupled fan I, a ribbed stripper 8 discharging the open fibrous material. The means for feeding the fibrous material to the cleaning and opening apparatus and for delivering same can be greatly v varied.
The encircling screens of the open-work cage g for the revolving beater d are in any case of such a construction that they tend to resist the passing through of valuable opened fibre, and the grid sections are capable of being readily detached orchanged to suit a change in size or shape of gap or aperture in the grid elements":
appropriate to the particular class of material,
but the character and arrangement of grid structure shown is appropriate for dealing witlrflax straw.
